Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a stamping die with adjustable depth. Background Technique

[0002] A stamping die is a tool used for metal stamping processing. It applies pressure to a metal sheet to deform it and form the required shape. The stamping die mainly includes two parts: the upper part and the lower part of the die. By applying pressure to the sheet, it is cut, punched, or formed in the shape of the die. It is widely used in industries such as automobiles, electronics, and household appliances, and can efficiently and precisely produce a large number of identical metal parts.

[0003] The stamping die needs to cooperate with the upper die and the lower die. Under the pressure of the upper die, the material is stamped into the required shape. At this time, the punching head of the upper die usually completely presses into the depression of the lower die. However, the depth of the stamping die cannot be adjusted, resulting in the thickness of the raw material after stamping not being able to be changed, thus causing the use effect of the die to be single and unable to meet various use requirements. For this reason, technical personnel in this field have proposed a stamping die with adjustable depth to solve the above problems. Summary of the Utility Model

[0004] In order to make up for the above deficiencies, the utility model provides a stamping die with adjustable depth, aiming to improve the problem that the depth of the stamping die in the prior art cannot be adjusted, resulting in the thickness of the raw material after stamping not being able to be changed, thus causing the use effect of the die to be single and unable to meet various use requirements.

[0006] Furthermore, the air blowing assembly includes a sleeve fixedly connected to the top of the support frame. A piston is slidably connected inside the sleeve. A connecting rod is fixedly connected to the bottom of the piston. A first one-way valve is installed at a through hole on one side of the top of the sleeve, and a second one-way valve is installed at a through hole on the other side of the top of the sleeve. A blow pipe is fixedly connected to the outside of the second one-way valve.

[0007] Furthermore, a lower mold is fixedly connected to the middle of the top end of the stamping seat. Guide rods are fixedly connected to the four corners of the top of the lower mold, and buffer springs are sleeved on the outside of the guide rods.

[0008] Furthermore, protective pads are fixedly connected to the four corners of the bottom of the upper mold, and the inside of the upper mold and the outside of multiple guide rods are slidably connected.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Refer to Figure 1 , Figure 3 and Figure 5, an embodiment provided by the present utility model: a stamping die with adjustable depth, including a stamping seat 1. A support frame 3 is fixedly connected to the top of the stamping seat 1. A hydraulic cylinder 4 is fixedly connected to the top of the support frame 3. The output end of the hydraulic cylinder 4 penetrates the bottom wall of the support frame 3 and is fixedly connected to an upper die 5. An installation groove 6 is formed in the bottom of the upper die 5. An installation plate 7 is installed inside the installation groove 6. A stamping head 8 is fixedly connected to the bottom of the installation plate 7. Two clamping grooves 14 are formed on both the front and rear sides of the installation plate 7. Limiting grooves 9 are formed on both the front and rear sides inside the upper die 5. A tension spring 10 is fixedly connected inside the limiting groove 9. One end of the tension spring 10 is fixedly connected to a moving block 11. Connecting rods 12 are rotatably connected to both the left and right sides of the moving block 11. The other end of the connecting rod 12 is rotatably connected to a clamping block 13. A pull rod 15 is fixedly connected to the other side of the moving block 11. The moving block 11 is slidably connected inside the limiting groove 9. One end of the pull rod 15 extends to the outside of the upper die 5. One end of the clamping block 13 penetrates the outer wall of the upper die 5 and is engaged with the inside of the clamping groove 14. Both the installation groove 6 and the installation plate 7 are provided in an I-shaped configuration, and the shapes of the installation groove 6 and the installation plate 7 match each other.

[0025] Specifically, the stamping seat 1 can make the contact area between the die and the bottom surface larger, so that it is more stable during stamping. The support frame 3 is fixed to the stamping seat 1, so that the support frame 3 can play a supporting role. Then, after the hydraulic cylinder 4 is installed, it can push the upper die 5 to move during operation to achieve the stamping operation. By pulling the pull rods 15 on both the front and rear sides of the upper die 5, the pull rods 15 drive the moving block 11 to slide inside the limiting groove 9. The limiting groove 9 can limit the movement of the moving block 11 to ensure the stable operation of the structure. At the same time, the moving block 11 stretches the tension spring 10, and then drives the two connecting rods 12 to rotate, so that the clamping block 13 connected to the other end of the connecting rod 12 moves, so that the clamping block 13 is disengaged from the clamping groove 14. In this way, the installation plate 7 can be separated from the upper die 5, realizing the disassembly of the stamping head 8, facilitating the replacement of stamping heads 8 with different thicknesses according to needs, and enabling the adjustment of the stamping depth, improving the flexibility of the die use, and thus producing products with different thicknesses.

[0026] Refer to Figure 1 and Figure 4, on both sides of the left side of the top of the support frame 3, there are blowing components arranged. The blowing components are used to remove debris on the surface of the mold. The blowing components include a sleeve 16. The sleeve 16 is fixedly connected to the top of the support frame 3. A piston 18 is slidably connected inside the sleeve 16. A connecting rod 19 is fixedly connected to the bottom of the piston 18. A first one-way valve 20 is installed at the through hole on one side of the top of the sleeve 16. A second one-way valve 21 is installed at the through hole on the other side of the top of the sleeve 16. A blowing pipe 17 is fixedly connected to the outside of the second one-way valve 21. The bottom end of the connecting rod 19 passes through the bottom wall of the support frame 3 and is fixedly connected to the top of the upper mold 5. The other end of the blowing pipe 17 extends above the lower mold 2 and is provided with a nozzle.

[0027] Specifically, by fixing the sleeve 16 on the top of the support frame 3, it can ensure that its internal structure remains stable during operation, and then the movement of the connecting rod 19 is driven by the movement of the upper mold 5. When the upper mold 5 moves downward, the connecting rod 19 will pull the piston 18 downward, so that air can enter the inside of the sleeve 16 through the first one-way valve 20. When the upper mold 5 moves upward, the connecting rod 19 will push the piston 18 upward, and then the air inside the sleeve 16 is discharged from the second one-way valve 21 and sprayed out from the nozzle at the end through the delivery of the blowing pipe 17, which can blow away the debris remaining on the surface after the mold stamping, reduce the influence of the debris on the material stamping, improve the precision of the product after stamping, and ensure the product quality.

[0028] Refer to Figure 1 and Figure 2 , in the middle of the top end of the stamping seat 1, there is a lower mold 2 fixedly connected. At the four corners of the top of the lower mold 2, there are guide rods 22 fixedly connected. Buffer springs 23 are sleeved outside the guide rods 22. At the four corners of the bottom of the upper mold 5, there are protective pads 24 fixedly connected. The inside of the upper mold 5 and the outside of multiple guide rods 22 are slidably connected.

[0029] Specifically, the movement of the upper mold 5 is guided by multiple guide rods 22, so that the movement direction of the upper mold 5 will not deviate during stamping, and it can be accurately docked with the lower mold 2, improving the stamping accuracy. At the same time, the buffer springs 23 sleeved outside the guide rods 22 cooperate with the protective pads 24 fixed at the bottom of the upper mold 5, which can reduce the impact force during stamping, improve the anti-collision ability of the mold, and thus extend the service life of each part.

[0030] Working principle: When using this mold, if you want to change the stamping depth, you can pull the pull rods 15 on the front and rear sides of the upper mold 5, so that the pull rods 15 drive the moving block 11 to slide inside the limit groove 9, and at the same time stretch the tension spring 10. Through the movement of the moving block 11, the two connecting rods 12 rotate, and then drive the movement of the clamping blocks 13 connected to the other ends respectively, so that the clamping blocks 13 are disengaged from the clamping grooves 14, so that the mounting plate 7 can be separated from the upper mold 5, realizing the disassembly of the stamping head 8. Then replace the stamping head 8 with different thicknesses, and repeat the above steps during installation. Subsequently, insert the mounting plate 7 into the installation groove 6, and make the clamping block 13 insert into the clamping groove 14 through the contraction of the tension spring 10, thus realizing the installation and fixation of the stamping head 8. In this way, the depth of the upper mold 5 punching into the lower mold 2 when punching down can be changed, so as to realize the adjustment of the stamping depth, improve the flexibility of the mold use, and facilitate replacing the stamping head 8 with different thicknesses according to needs, so as to produce products with different thicknesses.

[0031] Secondly, when the mold is stamping, the hydraulic cylinder 4 is used to push the upper mold 5 to move downward, and then drive the movement of the two connecting rods 19, so that the connecting rods 19 drive the piston 18 to slide inside the sleeve 16. At this time, air will enter the inside of the sleeve 16 from the first one-way valve 20. When the upper mold 5 moves upward after stamping, the connecting rod 19 can push the piston 18 upward, and then discharge the air inside the sleeve 16 from the second one-way valve 21, and spray it out from the nozzle at the end through the delivery of the air blowing pipe 17, so that the debris on the surface of the mold can be sprayed off, avoiding the influence of the debris on the material stamping, improving the accuracy of the product after stamping, and ensuring the product quality.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
