Description

Technical Field

[0001] The invention relates to the technical field of stamping dies, in particular to an intelligent auxiliary design method for automobile covering part dies. Background Art

[0002] Intelligent manufacturing of mold groups refers to the use of advanced automation technology, computer-aided design, computer-aided manufacturing, artificial intelligence and other technical means to achieve efficient, high-quality and low-cost production methods in the mold manufacturing process.

[0003] In this process, the design, manufacturing and testing of the mold set are all crucial. Among them, the choice of material is an important decision-making factor when designing the mold. Different materials have different physical, chemical and mechanical properties, which will affect the service life of the mold, manufacturing cost and the performance of the final product.

[0004] Molds made of different materials need to be processed and verified. In the prior art, molds of different materials need to be replaced manually during the mold design process, which has low work efficiency. Therefore, the patent with announcement number CN113275465B discloses a fast stamping mold with a variable stamping shape, which mainly controls the rotation of the first motor by the control panel to drive the mold replacement device to rotate, thereby replacing the mold. The control panel controls the rotation of the second motor to drive the rotating shaft to rotate the rotating seat downward, and the control panel controls the electric telescopic rod to push the mold above the pad, which reduces the time for workers to replace the mold and improves the efficiency of the workers. Although the patent can realize automatic replacement of molds according to different parts (equivalent to the replacement of molds of different materials in the present invention), it requires multiple sets of transmission structures for transportation during replacement, which has low practicality and high energy consumption.

[0005] When stamping the mold, heat is generated, which makes it difficult to quickly take out the parts, resulting in a long mold design verification cycle. When the above patent presses the mold down through the pressure plate, the nozzle will spray the coolant in the water tank to cool the mold. The sprayed coolant will flow into the water tank from the water inlet on the pad and then be discharged through the drain to prevent the staff from being scalded when they directly touch the parts. Although the patent solves the problem of cooling the mold and parts, the use of a single water cooling method will consume a lot of water resources, and spraying the coolant directly on the mold surface will accelerate the deformation and damage of the mold.

[0006] In the present invention, the stamping effects of molds of different materials are quickly verified during the mold design process through an auxiliary design device. In addition, the present invention can automatically adjust the clamping force according to the physical properties of the molds of different materials, and can also adjust the spraying amount of the coolant according to the clamping force. At the same time, the spraying method is adjusted to improve the verification efficiency in the mold design process. Summary of the invention

[0052] The first upper mold 5, the second upper mold 6 and the third upper mold 7 are placed inside the placement rack 4. The upper surfaces of the first upper mold 5, the second upper mold 6 and the third upper mold 7 are provided with convex grooves to be clamped with the limiting clamping plate 103, and the lower surfaces of the first upper mold 5, the second upper mold 6 and the third upper mold 7 are fixedly connected with guide columns 11; the lower mold 8 is placed above the workbench 3; the surface of the workbench 3 is provided with slots 9 and positioning holes 10, and the slots 9 and the positioning holes 10 are arranged in several groups on the surface of the workbench 3.

[0053] Furthermore, several groups of guide posts 11 are arranged on the lower surfaces of the first upper mold 5, the second upper mold 6 and the third upper mold 7, and several through holes are opened on the surface of the lower mold 8. The positions of the guide posts 11 correspond to the through holes and the positioning holes 10 respectively, and the through holes on the surface of the guide posts 11 and the lower mold 8 are arranged in a conical shape, which has a guiding function and is conducive to the fitting of the mold group.

[0054] Among them, the first upper mold 5 is made of plastic. The thermal expansion coefficient of plastic is large and is significantly affected by temperature. During the processing, the volume and shape of the plastic will change due to temperature changes. In order to avoid demolding of the plastic and the mold, it is necessary to ensure that the clamping force is sufficient when clamping the plastic mold; the second upper mold 6 is made of metal. Metal has good thermal conductivity and is easy to generate heat during the processing, resulting in changes in the mold temperature. In order to ensure processing accuracy and prevent mold deformation, the mold clamping force of the metal material needs to be moderate; the third upper mold 7 is made of composite material. Composite material is composed of a variety of materials. Its mechanical properties and processing process are very different from other materials. It has good thermal stability and needs to appropriately reduce the clamping force.

[0055] A through groove is arranged inside the driving piston rod 308 , and one-way valves are arranged inside the water inlet pipe 302 , the drain pipe 303 , the exhaust pipe 306 and the driving piston rod 308 .

[0056] Working principle: an external motor is arranged on the surface of the active rotating shaft 104, and the motor converts electrical energy into kinetic energy to drive the active rotating shaft 104 to rotate; the first upper mold 5, the second upper mold 6 and the third upper mold 7 are placed above the conveyor belt 106 inside the placement rack 4, and the lower mold 8 is placed above the workbench 3. The lower mold 8 has a stable support on the surface of the workbench 3, and the lower mold 8 can be replaced manually. The material of the replaced lower mold 8 needs to correspond to the first upper mold 5, the second upper mold 6 and the third upper mold 7.

[0057] When it is necessary to verify the designed mold sets of different materials; such as Figure 5 As shown, if the first upper mold 5 is verified, the external motor is started to drive the active rotating shafts 104 on both sides to rotate forward, thereby conveying the first upper mold 5 and the third upper mold 7 to the right together, and the second upper mold 6 on the limiting clamping plate 103 is squeezed to the right through the first upper mold 5, so that the second upper mold 6 is gradually separated from the limiting clamping plate 103, and the first upper mold 5 is gradually clamped with the limiting clamping plate 103 through the convex groove; when the limiting bar 107 pushes the first upper mold 5 to completely clamp with the limiting clamping plate 103, the conveyor belt 106 is disengaged from the first upper mold 5, and the motor is turned off at this time.

[0058] The punching machine 101 is started. The punching machine 101 drives the first upper mold 5 to slide downward through the punching rod 102 and the limit clamping plate 103. The first upper mold 5 slides downward and is clamped through the guide column 11 and the through groove on the surface of the lower mold 8, which improves the stability of the punching and plays a guiding role through the conical design. The punching machine 101 continues to move downward to perform the punching verification work.

[0059] During the rotation of the active shaft 104, the active shaft 104 drives the driven shaft 105 to rotate through the conveyor belt 106, and the driven shaft 105 rotates through the transmission belt 108 to drive the bidirectional screw rod 109 to rotate, and the bidirectional screw rod 109 rotates to control the two-side motion frames 211 to move toward each other on the surface of the workbench 3; at the same time, the punch rod 102 slides downward to drive the water tank 301 to move synchronously, and the spring 307 inside the water tank 301 always presses the driving piston rod 308 downward, so the water tank 301 slides downward to drive the driving piston rod 308 to slide synchronously, and the driving piston rod 308 drives the matching frame 212 to slide downward through the connecting seat 309;

[0060] like Figure 7As shown, the slide block 202 is driven to slide downward on the surface of the fixed column 201 through the matching frame 212, and the slide block 202 slides downward to drive the sliding tables 204 on both sides to move toward each other on the surface of the workbench 3 through the rubber rod 203, so as to laterally position the lower mold 8; at the same time, the slide block 202 slides downward to squeeze the lower end of the swing rod 208 outward through the hinge rod 207, and the upper end of the swing rod 208 swings inward under the limit of the moving frame 211, and the upper end of the swing rod 208 pushes the clamping plate 210 to slide inward through the push block 209, so as to squeeze the lower mold 8 of the same material as the first upper mold 5, so as to realize the clamping work;

[0061] Since the bidirectional screw rod 109 previously rotates to control the moving frames 211 on both sides to move inwardly toward each other, the hinge rod 207 pushes the swing rod 208 to swing at a larger angle, thereby increasing the clamping force on the first upper mold 5.

[0062] At the same time, since the downward movement of the matching frame 212 is achieved by driving the piston rod 308, and the movement of the driving piston rod 308 is achieved by the water tank 301 driving the spring 307 downward, after the clamping plate 210 and the lower mold 8 are stably clamped, the driving piston rod 308 is in a stuck state, and the water tank 301 that continues to move downward at this time gradually yields to the spring 307. As the height of the water tank 301 descends, the yield degree of the spring 307 is higher, and the spring 307 gradually forms a rigid state from an elastic state. During the downward movement of the first upper mold 5, the clamping plate 210 gradually evolves from an elastic clamping state to a rigid clamping state for the lower mold 8, realizing the change of the clamping force of the lower mold 8 from small to large, preventing the lower mold 8 from being deformed by the instantaneous clamping force before being fitted with the first upper mold 5, thereby improving the protection of the mold group.

[0063] When the water tank 301 is continuously moved downward and the driving piston rod 308 is stuck, the water tank 301 gradually pressurizes the coolant inside it downward, so that the coolant flows into the spray chamber 304 through the drain pipe 303, and the amount of liquid discharged is controlled by the time when the driving piston rod 308 is stuck. Since the moving frame 211 slides inward, the control distance of the hinge rod 207 is shortened, resulting in the early time of the driving piston rod 308 being stuck. In this way, the water tank 301 has sufficient pressure to discharge a large amount of coolant inside it. The first upper mold 5 made of plastic has a large thermal expansion coefficient and needs to be fully cooled to prevent deformation. The coolant flow rate is controlled in a targeted manner according to the material of the first upper mold 5 and the lower mold 8, which reduces the waste of coolant and improves the cooling effect.

[0064] When the stamping is completed, the punching machine 101 is started to reset. During the resetting process of the punching machine 101, the water tank 301 gradually releases the stored force of the spring 307, and the driving piston rod 308 gradually slides downward inside the water tank 301, and the gas inside the water tank 301 is discharged into the spray chamber 304 through the exhaust pipe 306, thereby pressurizing the coolant inside the spray chamber 304, and then spraying it through the spray pipe 205 to cool the mold group. The stamping of the coolant by the gas can make the coolant spray out in a mist form, thereby improving the uniformity of cooling the surface of the mold group; new coolant is injected into the water tank 301 through the water inlet pipe 302, thereby preparing for the next group of experiments.

[0065] Since the cooling of the mold set by the spray pipe 205 is performed at the same time as the resetting of the sliding table 204 and the first upper mold 5, the spraying area of ​​the mold set by the coolant sprayed by the spray pipe 205 is gradually expanded, thereby improving the cooling effect on the mold set.

[0066] When the third upper mold 7 needs to be verified, the external motor is controlled to reverse, and the first upper mold 5 is squeezed to the left through the third upper mold 7 to realize the replacement of the mold group; at this time, the bidirectional screw 109 is in a reverse state to control the two side motion frames 211 to slide outward. At this time, the thrust of the swing rod 208 by the hinge rod 207 is reduced, thereby reducing the swing range of the swing rod 208, and the clamping force of the clamping plate 210 on the mold group is correspondingly reduced; at the same time, the path of the swing rod 208 pushed by the hinge rod 207 is extended, and the coolant discharged from the water tank 301 is reduced. The existing mold made of composite materials has optimized its structure during the design process, has good heat dissipation, and does not require a large amount of coolant.
