Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, specifically to a support device for preventing deformation during stamping of thin-walled precision sheet metal parts. Background Technology

[0002] Sheet metal processing is a crucial skill that sheet metal technicians need to master, and it is also an important process in the forming of sheet metal products. Sheet metal processing includes traditional methods and process parameters such as cutting, blanking, and bending, as well as various cold stamping die structures and process parameters, the working principles and operation methods of various equipment, and new stamping technologies and processes. The processing of metal sheets for parts is called sheet metal processing. Among them, stamping in sheet metal processing is a production method that uses the plastic deformation of metal under external force to obtain raw materials, blanks or parts with certain shapes, dimensions and mechanical properties. This is called metal stamping.

[0003] According to a sheet metal processing anti-deformation stamping equipment with application number 202320448730.2, a pressing mechanism is provided to assist in fixing the sheet metal, and a second hydraulic rod is provided to push the top head to move upward and contact the punching flange to apply pressure and flatten it, thereby avoiding the deformation of the sheet metal parts caused by stamping and affecting their quality. This method can effectively prevent deformation of each sheet metal part during stamping.

[0004] However, the aforementioned sheet metal processing anti-deformation stamping equipment has certain shortcomings. This equipment uses a hydraulic rod to push the top of the stamped sheet metal after stamping to flatten it. It cannot fundamentally solve the problem of preventing deformation of sheet metal parts during stamping, thus having certain deficiencies. Therefore, we propose a thin-walled precision sheet metal stamping anti-deformation support device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a support device for preventing deformation during the stamping of thin-walled precision sheet metal parts, thus solving the problems mentioned in the background section.

[0007] Furthermore, the anti-deformation support mechanism includes two support seats, a punch die seat, a first mounting plate, and a hydraulic rod. The two support seats are disposed inside the convex groove. The punch die seat is fixedly installed on one side of the support seats, and the two punch die seats cooperate with each other. A connecting block is fixedly installed on one side of the support seat. Two sliding pins are fixedly installed on both sides of the connecting block. Several inclined sliding grooves that cooperate with the sliding pins are opened on both sides inside the convex groove. The sliding pins are slidably connected to the inclined sliding grooves. The two first mounting plates are respectively fixedly installed on both sides inside the material discharge channel. The hydraulic rod is fixedly installed on the top of the first mounting plate. A slider is fixedly installed at the output end of the hydraulic rod. Limiting plates are fixedly installed on both sides of the bottom of the connecting block. Two sliding rods are fixedly installed in the middle of the two limiting plates. The slider is slidably connected to the sliding rods.

[0008] Furthermore, a support plate is fixedly installed on one side of the top of the processing table, a top plate is fixedly installed on the top of the support plate, a stamping machine is fixedly installed on the bottom of the top plate, a second mounting plate is fixedly installed on the output end of the stamping machine, and pressure plate mechanisms are provided on both sides of the bottom of the second mounting plate.

[0009] Furthermore, the pressure plate mechanism includes several damping telescopic rods and two pressure plates. The several damping telescopic rods are respectively fixedly installed on both sides of the bottom of the second mounting plate, and the pressure plates are fixedly installed on the bottom of the two damping telescopic rods.

[0016] This utility model provides a support device for preventing deformation during stamping of thin-walled precision sheet metal parts, which has the following beneficial effects:

[0017] This anti-deformation support device for thin-walled precision sheet metal stamping, through the design of a convex groove, a blanking channel, and an anti-deformation support mechanism, allows the connecting block and support seat to move upward by activating a hydraulic rod to push the slider during sheet metal stamping. As the connecting block moves upward, the sliding pin moves laterally a certain distance due to the inclined characteristics of the inclined slide groove, causing the two support seats and the punch die seat to move closer together and upward. This allows the support seats and the punch die seat to support the stamping part of the sheet metal from below. During the stamping process, the punch head cooperates with the punch die seat, which can support the bottom punching position of the sheet metal from the punching position, effectively preventing deformation and the formation of flanges, thus fundamentally solving the problem of sheet metal stamping deformation.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Please see Figures 1 to 7This utility model provides a technical solution: a thin-walled precision sheet metal stamping anti-deformation support device, including a processing table 1 and a stamping table 2. The stamping table 2 is fixedly installed on the top of the processing table 1. A convex groove 3 is opened inside the stamping table 2, and a material feeding groove 4 is opened inside the processing table 1. An anti-deformation support mechanism is set inside the convex groove 3 and the material feeding groove 4. By setting the anti-deformation support mechanism, the bottom stamping position of the thin-walled precision sheet metal part to be stamped can be supported from inside the convex groove 3, thereby avoiding the deformation of the sheet metal part caused by stamping.

[0028] The anti-deformation support mechanism includes two support seats 5, a punch die seat 6, a first mounting plate 10, and a hydraulic rod 11. The two support seats 5 are located inside the convex groove 3. The punch die seat 6 is fixedly installed on one side of the support seat 5, and the two punch die seats 6 cooperate with each other. A connecting block 7 is fixedly installed on one side of the support seat 5. Two sliding pins 8 are fixedly installed on both sides of the connecting block 7. Several inclined sliding grooves 9 that cooperate with the sliding pins 8 are opened on both sides inside the convex groove 3. The sliding pins 8 are slidably connected to the inclined sliding grooves 9. The two first mounting plates 10 are respectively fixedly installed on both sides inside the material discharge channel 4. The hydraulic rod 11 is fixedly installed on the top of the first mounting plate 10. A slider 12 is fixedly installed on the output end of the hydraulic rod 11. Limit plates 13 are fixedly installed on both sides of the bottom of the connecting block 7. The two limit plates 12 are fixedly installed on both sides of the bottom of the connecting block 7. Two sliding rods 14 are fixedly installed in the middle of part 3, and the slider 12 is slidably connected to the sliding rods 14. By opening the hydraulic rod 11, the slider 12 and the connecting block 7 and the support seat 5 are pushed upward. When the connecting block 7 moves upward, the sliding pin 8 slides in the inclined groove 9. Due to the inclined characteristic of the inclined groove 9, the connecting block 7 moves laterally by a certain distance. At the same time, the slider 12 slides outside the sliding rod 14, so that the two support seats 5 and the punch die seat 6 can be brought together and merged. Then the sheet metal part can be stamped. After the stamping is completed, the scrap material left inside the two punch die seats 6 remains. Then the hydraulic rod 11 retracts, and the slider 12 drives the connecting block 7 and the support seat 5 to reset, so that the two punch die seats 6 can be separated. This allows the scrap material inside to fall off by gravity, avoiding the situation where the scrap material is blocked inside the punch die seat 6.

[0029] A support plate 15 is fixedly installed on one side of the top of the processing table 1. A top plate 16 is fixedly installed on the top of the support plate 15. A stamping machine 17 is fixedly installed on the bottom of the top plate 16. A second mounting plate 18 is fixedly installed on the output end of the stamping machine 17. Pressure plate mechanisms are provided on both sides of the bottom of the second mounting plate 18. By turning on the stamping machine 17, the second mounting plate 18 can be driven to move downward, thereby pressing the sheet metal part to be stamped onto the stamping table 2 through the pressure plate mechanism, so as to avoid the sheet metal part from shifting during stamping.

[0030] The pressure plate mechanism includes several damping telescopic rods 19 and two pressure plates 20. The several damping telescopic rods 19 are fixedly installed on both sides of the bottom of the second mounting plate 18, and the pressure plates 20 are fixedly installed on the bottom of the two damping telescopic rods 19. When the second mounting plate 18 is pushed down by the stamping machine 17, the pressure plate 20 at the bottom of the second mounting plate 18 will first contact the top of the thin-walled precision sheet metal part to be stamped on the stamping table 2. As the second mounting plate 18 gradually moves down, the damping telescopic rods 19 can retract and apply pressure to the pressure plate 20, so that the sheet metal part to be stamped can be pressed and fixed on the stamping table 2 by the pressure plate 20.

[0031] A return spring 21 is provided on the outer side of the damping telescopic rod 19, and the return spring 21 cooperates with the pressure plate 20. When the stamping machine 17 pushes the second mounting plate 18 down to press the sheet metal part onto the stamping table 2 through the pressure plate 20, the pressure plate 20 will squeeze the return spring 21 as the damping telescopic rod 19 retracts. After the stamping is completed, when the stamping machine 17 drives the second mounting plate 18 to move up and reset, the return spring 21 will rebound by its own elastic force, which can push the damping telescopic rod 19 to reset.

[0032] A punch head 22 is provided in the middle of the bottom of the second mounting plate 18. The punch head 22 cooperates with the punch die base 6. The punch head 22 can cooperate with the punch die base 6 to perform punching processing on sheet metal parts.

[0033] A scrap collection box 23 is provided below the processing table 1, and the scrap collection box 23 cooperates with the material discharge channel 4. By setting the scrap collection box 23, the scrap generated during stamping can be caught and collected during the discharge, which is convenient for subsequent processing.

[0034] After the two punch die bases 6 are engaged with each other, a stamping hole is formed in the middle. The middle of the two punch die bases 6 is an arc-shaped hollow. When the two punch die bases 6 are brought together, the arc-shaped hollow in the middle will form a stamping hole. The stamping head 22 engages with the stamping hole when stamping.

[0035] The punch die holder 6 extends to the bottom of the material discharge channel 4; by extending the punch die holder 6 to the bottom of the material discharge channel 4, the stamped scrap can be guided and discharged, avoiding the situation where the stamped scrap falls onto the first mounting plate 10 inside the material discharge channel 4 and cannot be effectively discharged.

[0036] The bottom of the pressure plate 20 is provided with an anti-slip pad; the protective pad at the bottom of the pressure plate 20 increases the stability when pressing the sheet metal parts and avoids displacement when stamping the sheet metal parts.

[0037] In summary, this anti-deformation support device for thin-walled precision sheet metal stamping only requires placing the sheet metal to be stamped on the top of the convex groove 3 on the stamping table 2. Then, by activating the hydraulic rod 11, the slider 12 and connecting block 7 are pushed upwards along with the support base 5. As the connecting block 7 moves upwards, the sliding pin 8 slides within the inclined groove 9. Due to the inclined nature of the groove 9, the connecting block 7 moves laterally a certain distance, while the slider 12 slides outside the sliding rod 14. This allows the two support bases 5 and the punch die base 6 to come together, forming a stamping hole in the center of the punch die base 6. Then, activating the stamping machine 17 pushes the second mounting plate 18 downwards. The pressure plate 20 at the bottom of the second mounting plate 18 will first contact the thin-walled precision sheet metal to be stamped on the stamping table 2. When the second mounting plate 18 gradually moves downward, the damping telescopic rod 19 retracts and applies pressure to the pressure plate 20, thus pressing and fixing the sheet metal part to be stamped onto the stamping table 2. As the stamping machine 17 pushes the second mounting plate 18 to continue moving downward, the damping telescopic rod 19 contracts after being squeezed, causing the stamping head 22 at the bottom of the second mounting plate 18 to continue moving downward, thus stamping the sheet metal part. The scrap material generated after stamping remains inside the punch die 6. Subsequently, the hydraulic rod 11 retracts, which drives the connecting block 7 and the support seat 5 to reset through the slider 12, thus separating the two punch die 6, allowing the scrap material inside to fall into the scrap material collection box 23 by gravity.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
