Description
Technical Field
[0001] This utility model relates to the field of stamping devices, specifically a stamping device for pressing multi-step metal sheet metal parts. Background Technology
[0002] A stamping device is a mechanical device that applies external force to sheet metal, strip metal, tube metal, and profile metal through a press and a die, causing plastic deformation or separation to obtain workpieces of the required shape and size. The device mainly consists of a press, a die, and an auxiliary system. Due to its advantages of high efficiency, high precision, and low cost, stamping devices are widely used in many fields such as automobiles, aerospace, and electronics, and are one of the key equipment for realizing the forming and processing of metal materials.
[0003] When pressing metal sheet metal parts into multi-step shapes, traditional stamping equipment usually uses multi-station dies or progressive dies. First, the metal sheet metal part is placed in the initial station of the die. The press drives the upper die to move downward, applying pressure to the sheet metal part, causing it to undergo plastic deformation under the constraint of the die cavity to form the first step. Then, the sheet metal part is transferred to the next station by mechanical transmission or manual handling, and stamped again, in sequence to complete the forming of multiple steps.
[0004] However, when this traditional stamping device extrudes sheet metal parts, the resulting step difference is usually fixed. This limitation makes it difficult to adjust the step difference parameters to meet diverse design requirements during the production process of sheet metal parts, resulting in a relatively limited range of sheet metal parts produced. Utility Model Content
[0005] Therefore, the purpose of this utility model is to provide a stamping device for pressing multi-step metal sheet parts, so as to solve the technical problem that the types of metal sheet parts processed and produced by traditional stamping devices are relatively limited.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a stamping device for pressing multi-step metal sheet metal parts, comprising a first stamping plate and a second stamping plate, a fixed seat fixed to the top of the first stamping plate, two sets of hydraulic cylinders installed at the top of the fixed seat, a second stamping plate provided at the bottom of the first stamping plate, a stamping block provided inside the second stamping plate, two sets of fixed blocks fixed to both sides of the stamping block, a spring installed at the bottom of the fixed block, a slot provided at the bottom of the stamping block, and a first pad and a second pad installed inside the slot.
[0007] By adopting the above technical solution, the problem of the limited variety of metal sheet metal parts produced by traditional stamping equipment is solved. When producing sheet metal parts with a step difference of 2cm, the hydraulic cylinder drives the first stamping plate to move downward, so that the distance between the first stamping plate and the second stamping plate is 2cm. Then, multiple sets of fixing bolts are taken out from the first fixing hole. The spring in the compressed state pushes the stamping block upward through the fixing block until the stamping block contacts the bottom of the first stamping plate. Then, the first pad is inserted into the slot, and the fixing bolts are installed in the second fixing hole, so that the fixing bolts are inserted into the fixing groove of the fixing block. Finally, the above steps are repeated to adjust the stamping block inside the first stamping plate, so that the device can produce sheet metal parts with a step difference of 2cm.
[0008] The present invention is further configured such that multiple sets of fixing grooves are formed inside the fixing blocks, and fixing bolts are installed inside the fixing grooves.
[0009] Preferably, after the stamping block has been adjusted, the fixing bolt fixes the stamping block through the fixing block, making the stamping block more secure.
[0010] The present invention is further configured such that multiple sets of first fixing holes and second fixing holes are respectively provided on both sides of the second stamping plate, and the height of the first fixing holes is lower than that of the second fixing holes.
[0011] Preferably, when the height of the stamping block protruding from the second stamping plate is 1cm, the fixing groove on the fixing block corresponds to the second fixing hole; when the height of the stamping block protruding from the second stamping plate is 2cm, the fixing groove on the fixing block corresponds to the first fixing hole.
[0012] The present invention is further configured such that the height difference between the first fixing hole and the second fixing hole is equal to the thickness difference between the first pad and the second pad.
[0013] Preferably, when producing sheet metal parts with a step difference of 2cm, simply insert the first pad into the slot. The first pad supports the bottom of the stamping block, and the fixing bolt is installed in the second fixing hole. The fixing bolt reinforces the stamping block through the second fixing hole.
[0014] The present invention is further configured such that the thickness of the first pad and the second pad is 1cm, and both the first pad and the second pad are made of alloy steel.
[0015] Preferably, when the first pad is inserted into the slot, the device produces a sheet metal part with a 2cm step difference, and when the second pad is inserted into the slot, the device can produce a sheet metal part with a 3cm step difference.
[0016] The present invention is further configured such that the outer wall of the first pad has two sets of protrusions, and the inner wall of the second pad has two sets of grooves.
[0017] Preferably, when both the first pad and the second pad are inserted into the slot, the protrusion on the first pad fixes the second pad, so that the first pad and the second pad will not slide during stacking.
[0018] The present invention is further configured such that the protrusion is arc-shaped and the diameter of the protrusion is the same as the diameter of the groove.
[0019] Preferably, both the protrusions and the grooves are rounded to facilitate stacking the first and second pads.
[0020] The present invention is further configured such that the inner wall of the fixing groove is provided with an internal thread, and one end of the fixing bolt is provided with an external thread.
[0021] Preferably, the fixing bolt and the fixing block are connected by threads, which makes it convenient for personnel to reinforce the stamping block.

This utility model solves the problem of the limited variety of metal sheet metal parts produced by traditional stamping devices by setting up a first stamping plate, a second stamping plate, a stamping block, a spring, a first pad, and a second pad. When producing sheet metal parts with a step difference of 2cm, the hydraulic cylinder drives the first stamping plate downward to make the distance between the first stamping plate and the second stamping plate 2cm. Then, multiple sets of fixing bolts are taken out from the first fixing hole. The spring in the compressed state pushes the stamping block upward through the fixing block until the stamping block contacts the bottom of the first stamping plate. Then, the first pad is inserted into the slot, and the fixing bolts are installed in the second fixing hole so that the fixing bolts are inserted into the fixing groove of the fixing block. Finally, the above steps are repeated to adjust the stamping block inside the first stamping plate, so that the device can produce sheet metal parts with a step difference of 2cm.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0034] The embodiments of this utility model will be described below based on its overall structure.
[0035] First embodiment:
[0036] Please see Figure 1 — Figure 5The system includes a first stamping plate 1 and a second stamping plate 2. A fixing seat 101 is fixed to the top of the first stamping plate 1, and two sets of hydraulic cylinders 102 are mounted on the top of the fixing seat 101. The second stamping plate 2 is located at the bottom of the first stamping plate 1. A stamping block 3 is located inside the second stamping plate 2. Two sets of fixing blocks 301 are fixed to both sides of the stamping block 3. A spring 305 is mounted at the bottom of the fixing block 301. A slot 201 is located at the bottom of the stamping block 3, and a first pad 4 and a second pad 402 are installed inside the slot 201. This system solves the problem of the limited variety of metal sheet metal parts produced by traditional stamping devices. For example, when producing sheet metal parts with a step difference of 2cm, the hydraulic cylinders 102 can be used to... The first stamping plate 1 is moved downwards, so that the distance between the first stamping plate 1 and the second stamping plate 2 is 2cm. Then, multiple sets of fixing bolts 306 are taken out from the first fixing hole 303. The spring 305, which is in a compressed state, pushes the stamping block 3 upwards through the fixing block 301 until the stamping block 3 contacts the bottom of the first stamping plate 1. Then, the first pad 4 is inserted into the slot 201, and the fixing bolt 306 is installed in the second fixing hole 304, so that the fixing bolt 306 is inserted into the fixing groove 302 of the fixing block 301. Finally, the above steps are repeated to adjust the stamping block 3 inside the first stamping plate 1, so that the device can produce sheet metal parts with a step difference of 2cm.
[0037] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 The fixing block 301 has multiple fixing grooves 302 inside, and fixing bolts 306 are installed inside the fixing grooves 302. After the stamping block 3 is adjusted, the fixing bolts 306 fix the stamping block 3 through the fixing block 301, making the stamping block 3 more firmly fixed.
[0038] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 The second stamping plate 2 has multiple sets of first fixing holes 303 and second fixing holes 304 on both sides. The height of the first fixing hole 303 is lower than that of the second fixing hole 304. When the height of the stamping block 3 protruding from the second stamping plate 2 is 1cm, the fixing groove 302 on the fixing block 301 corresponds to the second fixing hole 304. When the height of the stamping block 3 protruding from the second stamping plate 2 is 2cm, the fixing groove 302 on the fixing block 301 corresponds to the first fixing hole 303.
[0039] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 and Figure 5The height difference between the first fixing hole 303 and the second fixing hole 304 is equal to the thickness difference between the first pad 4 and the second pad 402. When producing sheet metal parts with a step difference of 2cm, the first pad 4 is simply inserted into the slot 201. The first pad 4 supports the bottom of the stamping block 3, and the fixing bolt 306 is installed in the second fixing hole 304. The fixing bolt 306 reinforces the stamping block 3 through the second fixing hole 304.
[0040] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 The thickness of the first pad 4 and the second pad 402 is 1cm, and both the first pad 4 and the second pad 402 are made of alloy steel. When the first pad 4 is inserted into the slot 201, the device produces sheet metal parts with a 2cm step difference. When the second pad 402 is inserted into the slot 201, the device can produce sheet metal parts with a 3cm step difference.
[0041] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 The outer wall of the first pad 4 is fixed with two sets of protrusions 401, and the inner wall of the second pad 402 is provided with two sets of grooves 403.

[0042] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 The protrusion 401 is set in an arc shape, and the diameter of the protrusion 401 is the same as the diameter of the groove 403. Both the protrusion 401 and the groove 403 are set in an arc shape, which makes it convenient for personnel to stack the first pad 4 and the second pad 402.
[0043] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 and Figure 4 The inner wall of the fixing groove 302 is provided with internal threads, and one end of the fixing bolt 306 is provided with external threads. The fixing bolt 306 and the fixing block 301 are connected by threads, which makes it convenient for personnel to reinforce the stamping block 3.
[0044] Second embodiment:

A first adjusting plate 5 and a second adjusting plate 502 are movably installed between the two sets of connecting blocks 501. The thickness of the first adjusting plate 5 is 3cm and the thickness of the second adjusting plate 502 is 2cm. When adjusting the height of the stamping block 3 on the second stamping plate 2, the first adjusting plate 5 is flipped to the top of the second stamping plate 2. The hydraulic cylinder 102 pushes the first stamping plate 1 downward. When the bottom wall of the first stamping plate 1 contacts the first adjusting plate 5, the hydraulic cylinder 102 stops. The setting and installation of the first adjusting plate 5 and the second adjusting plate 502 facilitate the adjustment of the distance between the first stamping plate 1 and the second stamping plate 2 by personnel.
[0046] In practical operation, when the stamping block 3 on the second stamping plate 2 is adjusted upwards, the hydraulic cylinder 102 drives the first stamping plate 1 to move downwards, making the distance between the first stamping plate 1 and the second stamping plate 2 2cm. Then, the multiple sets of fixing bolts 306 fixed inside the first fixing hole 303 are taken out. The spring 305, which is in a compressed state, pushes the stamping block 3 upwards through the fixing block 301 until the stamping block 3 contacts the bottom of the first stamping plate 1. Then, the first pad 4 is inserted into the slot 201, and the fixing bolts 306 are installed on the second stamping plate. The second fixing hole 304 on one side allows the fixing bolt 306 to be inserted into the fixing groove 302 of the fixing block 301, thereby completing the adjustment and fixing of the stamping block 3. If the stamping block 3 is adjusted upwards, the hydraulic cylinder 102 is controlled to drive the first stamping plate 1 to move, so that the distance between the first stamping plate 1 and the second stamping plate 2 is 3cm. Then the fixing bolt 306 is taken out from the second fixing hole 304, the spring 305 pushes the stamping block 3 upwards, and the personnel insert the second pad 402 into the slot 201, so that the second pad 402 and the first pad 4 are stacked.
