General steps of plastic parts designPlastic parts are designed on the basis of industrial modeling. First, see whether there are similar products for reference, and then carry out detailed functional decomposition of products and parts to determine the main process problems such as parts folding, wall thickness, demoulding slope, transition treatment between parts, connection treatment and strength treatment of parts.1. Similar reference


Before design, first look for similar products of the company and peers, what problems and deficiencies have occurred in the original products, and refer to the existing mature structure to avoid problematic structural forms.2. Determine the part discount, transition, connection and clearance treatment between partsUnderstand the modeling style from the modeling drawing and effect drawing, cooperate with the functional decomposition of the product, determine the number of parts (different surface states are either divided into different parts, or there must be over treatment between different surfaces), determine the over treatment between parts' surfaces, and determine the connection mode and fit clearance between parts.
3. Determination of part strength and connection strengthDetermine the wall thickness of the part body according to the product size. The strength of the part itself is determined by the wall thickness of the plastic part, the structural form (the plastic part in the shape of a flat plate has the worst strength), the stiffener and the stiffener. While determining the single strength of parts, the connection strength between parts must be determined. The methods to change the connection strength include: adding screw column, adding stop, adding buckle position and adding reinforcing bone against top and bottom.4. Determination of demoulding slope
The demoulding slope shall be comprehensively determined according to the material (PP, PE silica gel and rubber can be demoulded forcibly), surface state (the slope of decorative grain shall be greater than that of smooth surface, and the slope of etched surface shall be 0.5 degrees greater than that required by the template as far as possible, so as to ensure that the etched surface will not be damaged and improve the yield of products), transparency or not determines the demoulding slope of parts (the transparent slope shall be greater).Material types recommended by different product series of the companySurface treatment of plastic parts
Wall thickness selection of plastic partsFor plastic parts, the uniformity of wall thickness is required, and the workpiece with uneven wall thickness will have shrinkage traces. It is required that the ratio of stiffener to main wall thickness should be less than 0.4, and the maximum ratio should not exceed 0.6.Demoulding slope of plastic parts
In the construction of stereoscopic drawing, where the appearance and assembly are affected, the slope needs to be drawn, and the slope is generally not drawn for stiffeners.The demoulding slope of plastic parts is determined by the material, surface decoration status and whether the parts are transparent or not. The demoulding slope of hard plastic is greater than that of soft plastic. The higher the part, the deeper the hole, and the smaller the slope.Recommended demoulding slope for different materials
Numerical values of different accuracy in different size rangesDimensional accuracy of plastic partsGenerally, the accuracy of plastic parts is not high. In practical use, we mainly check the assembly dimensions, and mainly mark the overall dimensions, assembly dimensions and other dimensions that need to be controlled on the plan.
In practice, we mainly consider the consistency of dimensions. The edges of the upper and lower covers need to be aligned.Economic accuracy of different materialsNumerical values of different accuracy in different size ranges
Surface roughness of plastics1) The roughness of the etched surface cannot be marked. Where the plastic surface finish is particularly high, circle this range and mark the surface state as mirror.2) The surface of plastic parts is generally smooth and bright, and the surface roughness is generally ra2.5 0.2um.
3) The surface roughness of plastic mainly depends on the surface roughness of mold cavity. The surface roughness of mold is required to be one to two levels higher than that of plastic parts. The mold surface can reach ra0.05 by ultrasonic and electrolytic polishing.FilletThe fillet value of injection molding is determined by the adjacent wall thickness, generally 0.5 1.5 times of the wall thickness, but not less than 0.5mm.
The position of the parting surface shall be carefully selected. There is a fillet on the parting surface, and the fillet part shall be on the other side of the die. It is difficult to make, and there are fine trace lines at the fillet. However, fillet is required when anti cutting hand is required.Stiffener problemThe injection molding process is similar to the casting process. The non-uniformity of wall thickness will produce shrinkage defects. Generally, the wall thickness of reinforcement is 0.4 times of the main body thickness, and the maximum is no more than 0.6 times. The spacing between bars is greater than 4T, and the height of bars is less than 3T. In the method of improving the strength of parts, it is generally reinforced without increasing the wall thickness.
The reinforcement of the screw column shall be at least 1.0mm lower than the end face of the column, and the reinforcement shall be at least 1.0mm lower than the part surface or the parting surface.When multiple bars intersect, pay attention to the non-uniformity of wall thickness caused by the intersection.Design of stiffeners for plastic parts
Bearing surfacePlastic is easy to deform. In terms of positioning, it should be classified as the positioning of wool embryo. In terms of positioning area, it should be small. For example, the support of plane should be changed into small convex points and convex rings.Oblique roof and row position
The inclined top and row position move in the parting direction and perpendicular to the parting direction. The inclined top and row position shall be perpendicular to the parting direction, and there shall be sufficient movement space, as shown in the following figure:Treatment of plastic limit process problems1) Special treatment of wall thickness
For particularly large workpieces, such as the shell of toy cars, the wall thickness can be relatively thin by using the method of multi-point glue feeding. The local glue position of the column is thick, which is treated as shown in the following figure.Special treatment of wall thickness2) Treatment of small slope and vertical surface
The die surface has high dimensional accuracy, high surface finish, small demoulding resistance and small demoulding slope. In order to achieve this purpose, the parts with small inclination of the workpiece are inserted separately, and the inserts are processed by wire cutting and grinding, as shown in the figure below.To ensure that the side wall is vertical, the running position or inclined top is required. There is an interface line at the running position. In order to avoid obvious interface, the wiring is generally placed at the junction of fillet and large surface.Treatment of small slope and vertical surface
To ensure that the side wall is vertical, the running position or inclined top is required. There is an interface line at the running position. In order to avoid obvious interface, the wiring is generally placed at the junction of fillet and large surface.Problems often to be solved for plastic parts1) Transition processing problem
The accuracy of plastic parts is generally not high. There must be transition treatment between adjacent parts and different surfaces of the same part.Small grooves are generally used for transition between different surfaces of the same part, and small grooves and high-low staggered surfaces can be used between different parts, as shown in the figure.Surface over treatment
2) Clearance value of plastic partsParts are directly assembled without movement, generally 0.1mm;The seam is generally 0.15mm;
The minimum clearance between parts without contact is 0.3mm, generally 0.5mm.3) The common forms and clearance of plastic parts are shown in the figureCommon forms and clearance taking method of stop of plastic parts

As a machine tool mainly used to process box and shell parts, the machining center is worth hundreds of thousands to millions. It is generally the key equipment in the key processes of the enterprise. Once the machine is shut down, the loss is often great. Therefore, in order to give full play to the benefits of the machine tool, we must pay attention to the maintenance and repair work. Because most of the daily electrical faults of CNC machine tools are electrical faults, electrical maintenance and repair are more important.1) CNC system control part2) Servo motor and spindle motor


Focus on noise and temperature rise. If the noise or temperature rise is too large, find out whether it is a mechanical problem such as bearing or the parameter setting of its matching amplifier, and take corresponding measures to solve it. For example, if there is abnormal sound during the movement of the servo shaft, and there is no obvious parameter change after verification, it is suspected that the mechanical noise may be caused by the lead screw, coupling and non concentricity with the servo motor. Disconnect the motor from the coupling and operate the motor separately. If the motor still has noise, adjust the speed loop gain and position loop gain appropriately, Make the motor silent. If there is no noise, judge that it is the concentricity between the lead screw and the coupling, re correct the concentricity, and then connect with the motor. The problem can be eliminated.
3) Measurement feedback elementIncluding encoder, grating ruler, etc., check whether the connection of detection elements is loose and whether they are polluted by oil or dust.4) Electrical control part
Check whether the three-phase power supply voltage is normal; Check whether the electrical components are well connected; Check whether various switches are effective with the aid of CRT display diagnosis screen; Check whether all relays and contactors work normally and whether the contacts are in good condition; Whether the thermal relay, arc suppressor and other protective elements are effective; Check whether the temperature of components inside the electrical cabinet is too high. For poor contact of contactor contact, the contactor can be disassembled, the high-temperature oxide on the contact surface can be scraped off with a small file, then the sundries can be wiped out with absorbent cotton and alcohol, reassembled, and then the contact can be conducted with a multimeter.
5) Improve utilization
If the machining center is idle for a long time, when it needs to be used, first of all, each moving link of the machine tool will affect its static and dynamic transmission performance due to grease solidification, dust and even rust, reduce the accuracy of the machine tool, and the blockage of the oil circuit system is a big trouble; From the electrical point of view, the electrical control system hardware is composed of tens of thousands of electronic components, and their performance and life are very discrete. If it is not used for a long time, when power is suddenly transmitted, the components will be damaged in high current and strong voltage. Therefore, in a period of time without machining task, it is best to run the machine tool at a low speed, and at least power on the NC system frequently, or even every day.
I have encountered this situation: a horizontal machining center, using FANUC system. After running the warm-up program, it processed and found that the qualified parts were processed in the morning, and the processed parts were unqualified by noon. After inspection by the on-site processing personnel, the positioning and fixture on the machine tool are not deformed or loose. However, when the spindle box is not processed and stationary, it will deviate downward by 0.1mm along the direction of the gravity axis. The technician judges that the temperature compensation fails or the temperature sensor has poor contact. However, the phenomenon still occurs after replacing the temperature sensor and temperature module and re entering CNC parameters and temperature compensation parameters. After expert consultation, it was finally found that it was not the sensor problem, but that there was a 2-meter-long and 1-meter-wide skylight facing the main shaft and column on the machine tool. At noon, the sun directly shines on the main shaft and column, resulting in thermal deformation. After the skylight is covered, the spindle box returns to normal. This is a typical maintenance error caused by improper maintenance. Therefore, proper daily maintenance provides convenience for overall maintenance in the future.
