Description
Technical Field
[0001] This utility model relates to the field of stamping structure technology for precision metal structural parts, and particularly to a stamping structure for precision metal structural parts. Background Technology
[0002] With the development of high-end manufacturing fields such as aerospace, semiconductors, and medical devices, the demand for precision metal structural parts (such as chip packaging frames, aviation connectors, and micro sensor brackets) is increasing. Their dimensional accuracy requirements have increased from the traditional millimeter level to the micrometer level, and surface roughness requirements also need to meet stringent indicators such as complex shapes and ultra-thin wall thicknesses. Traditional stamping technology is unable to meet the manufacturing needs of high-end products due to problems such as insufficient mold precision, low degree of automation, and rough control of process parameters, and there is an urgent need for targeted technological upgrades.
[0003] The applicant discovered through a search that a Chinese patent discloses "A stamping structure for precision metal structural parts," with publication (announcement) number "CN213495867U." This patent mainly achieves clamping of both ends of the stamping material by setting symmetrical clamping fasteners at the top of the mounting base, thereby improving the stability of the metal structural parts during processing and thus enhancing the precision of the metal structural parts. However, this patent cannot achieve automated clamping and fixing of metal parts. In actual use, manual clamping depends on the operator's technique, and differences in the force applied by different personnel may lead to positioning deviations of the metal parts. Therefore, we propose a stamping structure for precision metal structural parts. Utility Model Content

In actual use, manual clamping depends on the operation method, and the difference in force applied by different people may lead to the positioning deviation of metal parts.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a stamping structure for precision metal structural parts, comprising a base plate, a support frame fixedly mounted on the top of the base plate, a hydraulic cylinder fixedly mounted on the top of the support frame, a pressure module fixedly connected to the lower end of the hydraulic cylinder, a die holder fixedly mounted in the middle of the top of the base plate and directly below the pressure module, an automatic clamping assembly provided on the top of the base plate, the automatic clamping assembly comprising a U-shaped frame, a motor and a guide rod, a hollow groove opened on the front of the U-shaped frame, a top groove opened on the top of the U-shaped frame, the motor connected to a moving block via a bidirectional lead screw, and a clamping plate and a rubber pad connected to the moving block via a connecting block.
[0006] As a preferred embodiment, the U-shaped frame is fixedly installed on the top of the base plate, the motor is fixedly connected to the outer right wall of the U-shaped frame, one end of the bidirectional lead screw is fixedly connected to the output end of the motor, and the other end of the bidirectional lead screw is rotatably connected to the inner left wall of the hollow groove.
[0007] As a preferred embodiment, the outer wall of the bidirectional lead screw is rotatably connected to the inner wall of the U-shaped frame, the guide rod is fixedly installed inside the hollow groove and located on the rear side of the bidirectional lead screw, one end of the moving block is threadedly connected to the outer wall of the bidirectional lead screw, and the other end of the moving block is slidably connected to the outer wall of the guide rod.
[0008] As a preferred embodiment, the connecting block is fixedly installed at the top center of the movable block, the clamping plate is fixedly installed at the top of the connecting block, and the rubber pad is fixedly connected to the surface of the clamping plate.
[0009] As a preferred embodiment, a cleaning component is provided on the top and inside of the support frame. The cleaning component includes a valve pipe. A liquid collection groove is provided on the top of the base plate and on the outside of the die holder. The valve pipe is fixedly installed on the right outer wall of the base plate. A water pump is fixedly installed on the top of the support frame and on the left side of the hydraulic cylinder. The output end of the water pump is fixedly connected to an output pipe.
[0010] As a preferred embodiment, the output pipe is fixedly installed on the top of the support frame, the bottom of the output pipe is fixedly connected to a branch pipe, the lower end of the branch pipe is fixedly connected to a branch pipe, and the branch pipe is fixedly installed on the inner bottom wall of the support frame.
[0011] As a preferred embodiment, the bottom of the branch pipe is fixedly connected to a plurality of nozzles that are evenly distributed, the input end of the water pump is fixedly connected to an input pipe, and a liquid storage tank is fixedly installed on the top of the base plate and directly below the input pipe.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] 1. With the automatic clamping assembly in place, the operator starts the motor, which drives the bidirectional lead screw to rotate, thereby causing two sets of moving blocks to move synchronously towards or away from each other along the guide rod, so that the two sets of clamping plates open and close automatically. Compared with traditional manual operation, this design can eliminate human error, reduce human intervention, and avoid clamping deviation caused by differences in operating techniques, thereby ensuring stable positioning of metal parts during stamping and improving stamping accuracy. The rubber pad provides flexible cushioning, which not only prevents scratches on the surface of the metal parts, but also enhances friction. It can be adapted to precision structural parts of different materials and shapes, thus broadening the application range of the equipment.
[0014] 2. With the cleaning components in place, workers can start the water pump to draw cleaning fluid from the storage tank. The fluid is then transported to the nozzle via the input pipe, output pipe, branch pipe, and tributary pipe. The cleaning fluid is then sprayed at high pressure onto the inner wall of the die holder. This flushes away metal shavings, oil, and other impurities from the inner wall of the die holder, preventing residues from affecting the accuracy of the die surface and ensuring stable dimensional tolerances for subsequent stamped parts. The waste liquid after cleaning flows into the collection tank and is discharged through the valve pipe. This prevents waste liquid from splashing and contaminating the stamping area, reduces the risk of equipment corrosion, and avoids frequent manual cleaning. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see the appendix Figure 1 Appendix Figure 3and appendix Figure 4 A stamping structure for precision metal structural parts includes a base plate 1, a support frame 2 fixedly mounted on the top of the base plate 1, a hydraulic cylinder 3 fixedly mounted on the top of the support frame 2, a pressure module 4 fixedly connected to the lower end of the hydraulic cylinder 3, a die seat 5 fixedly mounted in the middle of the top of the base plate 1 and directly below the pressure module 4, an automatic clamping assembly 6 provided on the top of the base plate 1, the automatic clamping assembly 6 including a U-shaped frame 601, a motor 604 and a guide rod 610, a hollow groove 602 opened on the front of the U-shaped frame 601, a top groove 603 opened on the top of the U-shaped frame 601, a moving block 606 connected to the motor 604 through a bidirectional lead screw 605, and a clamping plate 608 and a rubber pad 609 connected to the moving block 606 through a connecting block 607.
[0024] Hydraulic cylinder 3 provides stamping power and drives press module 4 to move vertically through hydraulic system to achieve stamping of metal parts. Press module 4 is a stamping tool that directly contacts the metal parts. It transmits the pressure of hydraulic cylinder 3 to the metal parts to complete the stamping action. Die seat 5 is located directly below press module 4 and serves as a support and forming mold for the metal parts. It works with press module 4 to complete precision stamping.
[0025] U-shaped frame 601 is fixedly installed on the top of base plate 1. Motor 604 is fixedly connected to the outer right side wall of U-shaped frame 601. One end of bidirectional lead screw 605 is fixedly connected to the output end of motor 604. The other end of bidirectional lead screw 605 is rotatably connected to the inner left side wall of hollow groove 602. The outer wall of bidirectional lead screw 605 is rotatably connected to the inner wall of U-shaped frame 601. Guide rod 610 is fixedly installed inside hollow groove 602 and located behind bidirectional lead screw 605. One end of moving block 606 is threaded to the outer wall of bidirectional lead screw 605. The other end of moving block 606 is slidably connected to the outer wall of guide rod 610.
[0026] The top groove 603 is located at the top of the U-shaped frame 601, allowing the connecting block 607 to slide therein, so that the horizontal movement of the two sets of moving blocks 606 is converted into the clamping movement of the two sets of clamping plates 608.
[0027] The connecting block 607 is fixedly installed at the top center of the movable block 606, the clamping plate 608 is fixedly installed at the top of the connecting block 607, and the rubber pad 609 is fixedly connected to the surface of the clamping plate 608.
[0028] The rubber pad 609 is fixed to the surface of the clamping plate 608, which can increase friction, prevent metal parts from sliding, and provide cushioning to avoid the clamping plate 608 from scratching or indenting the surface of precision metal parts.
[0029] Specifically, through the automatic clamping component 6, the operator turns on the motor 604, which drives the bidirectional lead screw 605 to rotate, thereby causing the two sets of moving blocks 606 to move synchronously towards or away from each other along the guide rod 610, so that the two sets of clamping plates 608 open and close automatically. Compared with traditional manual operation, this design can eliminate human error, reduce human intervention, and prevent clamping deviation caused by differences in operating techniques, thereby ensuring stable positioning of metal parts during stamping and improving stamping accuracy. The rubber pad 609 provides flexible cushioning, which not only avoids scratches on the surface of the metal parts, but also enhances friction. It can be adapted to precision structural parts of different materials and shapes, thus broadening the application range of the equipment.
[0030] Please see the appendix Figure 1 Appendix Figure 2 and appendix Figure 5 A cleaning component 7 is provided on the top and inside of the support frame 2. The cleaning component 7 includes a valve pipe 702. A liquid collection tank 701 is provided on the top of the base plate 1 and on the outside of the die seat 5. The valve pipe 702 is fixedly installed on the right outer wall of the base plate 1. A water pump 703 is fixedly installed on the top of the support frame 2 and on the left side of the hydraulic cylinder 3. The output end of the water pump 703 is fixedly connected to an output pipe 704.
[0031] The liquid collection tank 701 is located on the bottom plate 1 outside the mold base 5. It is used to collect the waste liquid generated during the cleaning process and is connected to the valve pipe 702. The discharge of waste liquid is controlled through the valve pipe 702.
[0032] The output pipe 704 is fixedly installed on the top of the support frame 2. The bottom of the output pipe 704 is fixedly connected to the diversion pipe 705. The lower end of the diversion pipe 705 is fixedly connected to the branch pipe 706. The branch pipe 706 is fixedly installed on the inner bottom wall of the support frame 2. The bottom of the branch pipe 706 is fixedly connected to multiple sets of nozzles 707 that are evenly distributed. The input end of the water pump 703 is fixedly connected to the input pipe 708. The liquid storage tank 709 is fixedly installed on the top of the base plate 1 and directly below the input pipe 708.
[0033] The nozzles 707 are set at an angle, and the spray direction is precisely aligned with the inner wall of the mold base 5. The number, spacing and spray angle of the nozzles 707 are optimized according to the size and shape of the mold base 5, so as to achieve full coverage cleaning.
[0034] Specifically, through the cleaning component 7, the operator can turn on the water pump 703 to draw cleaning fluid from the storage tank 709. The fluid is then transported to the nozzle 707 via the input pipe 708, output pipe 704, diversion pipe 705, and branch pipe 706. The cleaning fluid is then sprayed at high pressure onto the inner wall of the die holder 5. This flushes away metal shavings, oil stains, and other impurities from the inner wall of the die holder 5, preventing residues from affecting the accuracy of the mold surface and ensuring stable dimensional tolerances of subsequent stamped parts. The waste liquid after cleaning flows into the collection tank 701 and is discharged through the valve pipe 702. This prevents waste liquid from splashing and contaminating the stamping area, reduces the risk of equipment corrosion, and avoids frequent manual cleaning.
[0035] The working principle of this utility model is as follows: This utility model is a stamping structure for precision metal structural parts. First, the operator starts the motor 604, which drives the bidirectional lead screw 605 to rotate. Since the threads on both sides of the bidirectional lead screw 605 are in opposite directions, during rotation, it drives two sets of moving blocks 606 to move synchronously towards or away from each other along the guide rod 610. The two sets of moving blocks 606 drive two sets of clamping plates 608 to move through two sets of connecting blocks 607, so that the two sets of clamping plates 608 can automatically open and close. When it is necessary to clamp the metal part, the two sets of moving blocks 606 drive the two sets of clamping plates 608 to move towards each other, thus completing the stable clamping of the metal part. When releasing the metal part, the two sets of moving blocks 606 drive the two sets of clamping plates 608 to move away from each other. Then... After the stamping work is completed, the staff turns on the water pump 703. The water pump 703 draws cleaning fluid from the storage tank 709. The cleaning fluid is transported to the output pipe 704 through the input pipe 708. The output pipe 704 transmits the cleaning fluid to the distribution pipe 705. The distribution pipe 705 then distributes the cleaning fluid to the branch pipe 706. Finally, the cleaning fluid is sprayed at high pressure onto the inner wall of the die holder 5 through the nozzles 707 that are evenly distributed and inclined at the bottom of the branch pipe 706. After the cleaning fluid washes away the metal debris, oil stains and other impurities on the inner wall of the die holder 5, the waste liquid flows into the collection tank 701 located on the outer bottom plate 1 of the die holder 5. The staff opens the valve pipe 702 in time to discharge the waste liquid in the collection tank 701, thus completing the cleaning of the die holder 5 and the waste liquid treatment.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
