Description

Technical Field

[0001] This invention relates to the field of stamping die technology, specifically to a die fixing structure for stamping dies. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). They are called cold stamping dies (commonly known as cold stamping molds). Stamping is a pressure processing method that uses dies mounted on a press to apply pressure to materials at room temperature, causing them to separate or undergo plastic deformation, thereby obtaining the desired parts. The bases and shells of household metal products are formed by stamping using die stamping equipment.

[0003] According to the patent application "A Fixing Structure for Aluminum Plate Stamping Die (Publication No.: CN 218744205 U; Application No.: 202222909940.5)", the application addresses the problem that "in the process of processing aluminum plates with stamping dies, it is necessary to use corresponding irregular dies to stamp the aluminum plates and fix the irregular dies on the lower surface of the upper die, so that one stamping die can only process one irregular shape of aluminum plate, resulting in the need to use multiple stamping dies when processing multiple irregular shapes, which increases the overall processing cost." However, the device in the above application does not have a structure to limit the rocking mechanism during use. After the stamping die is installed, the fixing structure in the above device will gradually loosen over time, resulting in poor fixing effect. Summary of the Invention

[0018] Compared with the prior art, the present invention provides a die fixing structure for stamping dies, which has the following beneficial effects: 1. This stamping die uses a die fixing structure. Through the set fixing mechanism, the operator only needs to hold the rocker arm and rotate it to drive the first threaded rod to move downward within the inner ring of the first threaded cylinder, so that the positioning plate is completely engaged in the positioning groove to complete the fixing of the stamping die. The operation is simple and convenient for the operator to use. The operator can use the locking block and locking groove to position the stamping die during installation, so that the stamping die will not be misaligned with the worktable after installation. At the same time, the fixing rod is fixed to the front side of the worktable and slides to the rear side of the turntable through the limiting ring groove to limit the turntable, which increases the stability of the turntable during rotation and increases the structural strength of the turntable.

[0019] 2. The stamping die uses a die-fixing structure. Through the anti-rotation mechanism, the operator only needs to rotate the torsion ring to drive the friction block to move downward, so that the bottom of the friction block is in contact with the top of the turntable. This causes excessive friction between the top of the turntable and the bottom of the friction block, preventing the turntable from rotating further. This also prevents the worm gear from rotating after the stamping die is installed, increasing the stability of the stamping die after installation. The connecting sleeve plate fixed to the top of the second threaded rod is sleeved on the outer ring of the limit rod and moves up and down to limit the second threaded rod, preventing it from rotating and allowing it to move up and down only with the rotation of the second threaded cylinder.

[0020] 3. The stamping die uses a die fixing structure. With the reinforcement mechanism, the operator only needs to move the levers on the left and right sides inward to move the positioning rods on the left and right sides inward and retract them into the fixing box to complete the disassembly or installation of the stamping die. The operation is simple and convenient for the operator. At the same time, after the stamping die is installed, the slide will always maintain the force of moving outward under the action of the compression spring, which increases the stability of the stamping die after installation.

[0024] This invention provides a technical solution: Example 1

[0026] The fixing mechanism 1 includes a snap-fit ​​assembly 11, a connecting assembly 12, a transmission assembly 13, and a rocking assembly 14. The snap-fit ​​assembly 11 is disposed inside the stamping die 6, the connecting assembly 12 is disposed at the bottom of the worktable 4, the transmission assembly 13 is disposed to the right of the connecting assembly 12, and the rocking assembly 14 is disposed in front of the transmission assembly 13.

[0027] The snap-fit ​​assembly 11 includes a snap-fit ​​block 1101, which is fixedly connected to the bottom of the stamping die 6. A snap-fit ​​groove 1102 is provided on the top of the worktable 4 corresponding to the snap-fit ​​block 1101. A positioning plate 1103 is snap-fitted into the bottom of the stamping die 6. A positioning groove 1104 is provided on the bottom of the stamping die 6 corresponding to the positioning plate 1103. A first threaded rod 1105 is fixedly connected to the bottom of the positioning plate 1103. The first threaded rod 1105 is sleeved inside the worktable 4 and the bottom of the stamping die 6. The connecting assembly 12 includes a first threaded cylinder 1201, which is threadedly connected to the outer ring of the first threaded rod 1105. A convex ring 1202 is fixedly connected to the top of the first threaded cylinder 1201. A fixing collar 1203 is rotatably connected to the outer side of the convex ring 1202. The fixing collar 1203 is fixedly connected to the bottom of the worktable 4. The transmission assembly 13 includes a worm gear 1301, which is fixedly connected to the first threaded cylinder 1105. On the outer ring of 201, a worm gear 1301 meshes with a worm 1302 on its right side. A support cylinder 1303 is rotatably connected to the rear end of the worm 1302. A first connecting block 1304 is fixedly connected to the top of the support cylinder 1303 and is fixedly connected to the bottom of the worktable 4. A connecting shaft 1305 is fixedly connected to the front side of the worm 1302. A support ring 1306 is rotatably connected to the outer ring of the connecting shaft 1305. The top of the support ring 1306 is fixed... A second connecting block 1307 is connected to the bottom of the worktable 4. The rocking assembly 14 includes a turntable 1401, which is fixedly connected to the front side of the connecting shaft 1305. A rocker arm 1402 is fixedly connected to the front side of the turntable 1401. A fixing rod 1403 is fixedly connected to the front side of the worktable 4 at the position corresponding to the turntable 1401. A limit ring groove 1404 is formed on the rear side of the turntable 1401 at the position corresponding to the fixing rod 1403.

[0028] Furthermore, the operator only needs to hold the rocker arm 1402 and rotate it to move the first threaded rod 1105 downward within the inner ring of the first threaded cylinder 1201, so that the positioning plate 1103 is completely engaged in the positioning groove 1104 to complete the fixing of the stamping die 6. The operation is simple and convenient for the operator. The operator can use the locking block 1101 and the locking groove 1102 to position the stamping die 6 during installation, so that the stamping die 6 will not be misaligned with the worktable 4 after installation. At the same time, the fixing rod 1403 is fixed to the front side of the worktable 4 and is slidably connected to the rear side of the turntable 1401 through the limiting ring groove 1404 to limit the turntable 1401, which increases the stability of the turntable 1401 during rotation and increases the structural strength of the turntable 1401. Example 2

[0029] See Figure 6 and Figure 7 Furthermore, based on Embodiment 1, the anti-rotation mechanism 2 includes a support component 21, a friction component 22, and a limiting component 23. The support component 21 is disposed on the front side of the worktable 4, the friction component 22 is disposed on the inner ring of the support component 21, and the limiting component 23 is disposed on the top of the friction component 22.

[0030] Support assembly 21 includes a support rod 2101, which is fixedly connected to the front side of the workbench 4. A support collar 2102 is fixedly connected to the front side of the support rod 2101. A rotating ring 2103 is rotatably connected to the inner ring of the support collar 2102. A second threaded cylinder 2104 is fixedly connected to the inner ring of the rotating ring 2103. A connecting arm 2105 is fixedly connected to the top of the outer ring of the second threaded cylinder 2104. A torsion ring 2106 is fixedly connected to the outer side of the connecting arm 2105. Friction assembly 22 includes a second threaded rod 2201. Rod 2201 is threaded to the inner ring of the second threaded cylinder 2104. Friction block 2202 is fixedly connected to the bottom of the second threaded rod 2201. The bottom of friction block 2202 fits against the top of turntable 1401. Limiting component 23 includes connecting sleeve 2301, which is fixedly connected to the top of the second threaded rod 2201. Limiting rod 2302 is sleeved on the rear side of connecting sleeve 2301. Limiting rod 2302 is fixedly connected to the top of worktable 4. Limiting piece 2303 is fixedly connected to the top of limiting rod 2302.

[0031] Furthermore: the operator only needs to rotate the torsion ring 2106 to drive the friction block 2202 to move downward, so that the bottom of the friction block 2202 is in contact with the top of the turntable 1401, so that the top of the turntable 1401 and the bottom of the friction block 2202 generate excessive friction, making the turntable 1401 unable to continue rotating, so that the worm gear 1302 cannot rotate after the stamping die 6 is installed, thus increasing the stability of the stamping die 6 after installation. The connecting sleeve 2301 fixed to the top of the second threaded rod 2201 is sleeved on the outer ring of the limiting rod 2302 and moves up and down to limit the second threaded rod 2201, so that the second threaded rod 2201 cannot rotate and can only move up and down with the rotation of the second threaded cylinder 2104. Example 3

[0032] See Figure 8 and Figure 9 Furthermore, based on Embodiment 1 and Embodiment 2, the reinforcement mechanism 3 includes a reset component 31, a positioning component 32, and a moving component 33. The reset component 31 is disposed on the bottom outer side of the stamping die 6, the positioning component 32 is disposed on the outer side of the reset component 31, and the moving component 33 is disposed on the top of the reset component 31.

[0033] The reset assembly 31 includes a fixed base 3101, which is fixedly connected to the bottom of the outer ring of the stamping die 6. The bottom of the fixed base 3101 is in contact with the top of the worktable 4. Fixed boxes 3102 are fixedly connected to the four outer corners of the fixed base 3101. A slide cylinder 3103 is slidably connected inside the fixed box 3102. A compression spring 3104 is fixedly connected inside the slide cylinder 3103. The positioning assembly 32 includes a positioning rod 3201, which is fixedly connected to the outside of the slide cylinder 3103. A positioning ring 3202 is sleeved on the outer ring of the positioning rod 3201. A fixing frame 3203 is fixedly connected to the outside of the positioning ring 3202. The fixing frame 3203 is fixedly connected to the top of the worktable 4. The moving component 33 includes a moving rod 3301, which is fixedly connected to the top of the slide cylinder 3103. A moving slide groove 3302 is provided on the top of the fixing box 3102 corresponding to the position of the moving rod 3301. A limiting arc piece 3303 is fixedly connected to the top of the moving rod 3301. The inner side of the limiting arc piece 3303 is in contact with the top of the fixing box 3102. A paddle 3304 is fixedly connected to the top of the limiting arc piece 3303.

[0034] Furthermore, the operator only needs to move the levers 3304 on both sides inward to move the positioning rods 3201 on both sides inward and retract them into the fixed box 3102 to complete the disassembly or installation of the stamping die 6. The operation is simple and convenient for the operator. At the same time, after the stamping die 6 is installed, the slide cylinder 3103 will always maintain the force of moving outward under the action of the compression spring 3104, which increases the stability of the stamping die 6 after installation.

[0035] In actual operation, when this device is used and the stamping die 6 needs to be installed, the operator first moves the levers 3304 on both sides of the stamping die 6 inward. The inward movement of the levers 3304 drives the moving rods 3301 on both sides to move inward through the limiting arc plate 3303. The inward movement of the moving rods 3301 drives the positioning rods 3201 on both sides to move inward through the slide cylinder 3103, so that the positioning rods 3201 on both sides retract into the fixed box 3102. Then, the staff uses the locking block 1101 and the locking slot 1102 to place the stamping die 6 on the top of the workbench 4, so that the bottom of the stamping die 6 fits against the top of the workbench 4. Then, the staff releases the limiting work of the left and right side levers 3304. At this time, the left and right side slide cylinders 3103 drive the positioning rod 3201 to move outward under the action of the compression spring 3104. The positioning rod 3201 moves outward and fits into the inner ring of the positioning ring 3202. At this time, the positioning work of the stamping die 6 is completed. Next, the worker inserts the first threaded rod 1105 from top to bottom into the stamping die 6 and the worktable 4. Then, the worker holds the rocker arm 1402 to rotate the turntable 1401. The rotation of the turntable 1401 causes the connecting shaft 1305 to rotate. The rotation of the connecting shaft 1305 drives the worm gear 1302 to rotate the worm wheel 1301. The rotation of the worm wheel 1301 drives the first threaded cylinder 1201 to rotate. The rotation of the first threaded cylinder 1201 causes the first threaded rod 1105 to move downwards in its inner ring until the positioning plate 1103 is engaged with the stamping die through the positioning groove 1104. Stop rotating the rocker arm 1402 when the die is at the bottom position of the die 6. Then, the operator rotates the torsion ring 2106. The rotation of the torsion ring 2106 drives the second threaded cylinder 2104 to rotate through the connecting arm 2105. The rotation of the second threaded cylinder 2104 drives the second threaded rod 2201 to move downward. The downward movement of the second threaded rod 2201 drives the friction block 2202 to move downward. The downward movement of the friction block 2202 makes it fit against the top of the turntable 1401 and rubs against the turntable 1401, making the turntable 1401 unable to rotate anymore. At this point, the installation of the stamping die 6 is completed.
