Description

Technical Field

[0001] The utility model relates to the technical field of stamping machines for cable assembly production, and more specifically, it relates to a stamping machine for cable assembly production. Background Art

[0002] In the existing cable assembly production technology, the stamping process of metal sheets often relies on manual operation. This traditional method not only has a high labor intensity but also low efficiency, which has an adverse impact on production efficiency and the health of workers. Manual stamping not only has limited speed but also poor consistency, easily leading to unstable product quality, increasing the defective rate, and thus increasing production costs.

[0003] In addition, in the prior art, the installation and disassembly operations of the upper die core and the lower die core of the stamping machine are usually rather cumbersome. When it is necessary to replace the die or perform maintenance, the operator needs to spend a lot of time and effort to complete this process, which not only prolongs the downtime of the production line but also increases the operation difficulty and affects the continuity and efficiency of production.

[0004] To solve these problems, some stamping machine devices adopt some mechanisms to achieve the quick disassembly and assembly of the upper die core and the lower die core. These mechanisms are designed to simplify the replacement and maintenance processes and improve production efficiency. However, these mechanisms often have a simple structure and low connection strength, resulting in unstable die installation. This unstable installation may cause the die to shift during the stamping process, affecting the stamping accuracy and even potentially leading to safety accidents. Summary of the Utility Model

[0029] It should be pointed out that unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs.

[0030] In the present invention, unless otherwise stated, the orientations such as "upper, lower" are usually in the directions shown in the drawings, or in the vertical, perpendicular or gravitational directions; similarly, for the convenience of understanding and description, "left, right" are usually in the left and right shown in the drawings; "inside, outside" refer to the inside and outside relative to the contours of the respective components, but the above orientation terms are not used to limit the present invention.

[0031] Please refer to Figures 1-6 , a stamping machine for cable assembly production, including a machine tool 1, characterized in that: a stamping device is arranged inside the machine tool 1, a quick-change device is arranged inside the machine tool 1, the quick-change device includes a clamping rod 2, a thread groove 3, a connecting rod 4, a control sleeve 5, a connecting sleeve 6 and a spring 7, the clamping rod 2 is connected to the outside of the connecting sleeve 6 through the spring 7, the thread groove 3 is opened on the outside of the connecting rod 4, the connecting sleeve 6 is detachably sleeved on the outside of the connecting rod 4, the control sleeve 5 is movably sleeved on the outside of the connecting sleeve 6, a strengthening mechanism is arranged on the outside of the connecting rod 4, the strengthening mechanism includes a relief groove 8, a limit frame 9, a threaded sleeve 10, a limit plate 11 and a limit sleeve 12, the relief groove 8 is opened on the limit sleeve 12, the limit frame 9 is fixedly connected to one side of the control sleeve 5, the threaded sleeve 10 is detachably sleeved on the outside of the connecting sleeve 6 through threads, the limit plate 11 is fixedly arranged inside the limit frame 9, and the limit sleeve 12 is movably sleeved on the outside of the connecting sleeve 6.

[0032] A fixing plate 13 is arranged on the outside of the connecting sleeve 6, a jack 14 is opened on the fixing plate 13, an inserting rod 15 is arranged on one side of the control sleeve 5, and the inserting rod 15 is adapted to the jack 14.

[0033] A first push spring 16 is movably sleeved outside the connecting sleeve 6. One end of the first push spring 16 is connected to the control sleeve 5, and the other end of the first push spring 16 is in contact connection with the limit sleeve 12.

[0034] A second push spring 17 is sleeved outside the connecting rod 4, and the second push spring 17 is movably installed inside the connecting sleeve 6.

[0035] In this embodiment, when the upper mold core 20 or the lower mold core 21 needs to be maintained and replaced, the limiting sleeve 12 is first rotated in the corresponding direction, and the limiting sleeve 12 drives the clearance groove 8 to move. Then, after the position of the clearance groove 8 corresponds to the limiting plate 11, the control sleeve 5 is pushed, and the control sleeve 5 drives the limiting frame 9 and the limiting plate 11 to move, so that the limiting frame 9 and the limiting plate 11 pass through the clearance groove 8. At the same time, the control sleeve 5 and the limiting sleeve 12 cooperate to squeeze the first push spring 16. When the first push spring 16 is squeezed to the limit, the corresponding limiting plate 11 just moves to the side of the limiting sleeve 12, and then the limiting sleeve 12 is rotated so that the position of the clearance groove 8 and the limiting plate 11 no longer corresponds, thereby making the corresponding limiting plate 1 1 is engaged with one side of the control sleeve 5 to prevent the control sleeve 5 from moving. At the same time, the outer side of the clamping rod 2 loses the limit of the inner wall of the control sleeve 5, and then the connecting sleeve 6 is pulled in the corresponding direction. The side wall of the thread groove 3 squeezes one end of the clamping rod 2. Since one end of the clamping rod 2 is a rounded structure design, and the spring 7 only provides a weak reset force, the clamping rod 2 will be ejected to the outside of the thread groove 3. At the same time, the clamping rod 2 drives the spring 7 to stretch, and then the connecting sleeve 6 can be removed, and then the upper mold core 20 and the lower mold core 21 can be removed, and then the replaced upper mold core 20 and the lower mold core 21 can be installed to the corresponding position, and the corresponding installation groove 23 and the sliding groove 22 are aligned, and then the connecting rod 4 passes through the sliding groove 2 2 and the installation groove 23, and then the connecting sleeve 6 is sleeved on the outside of the connecting rod 4, and then the spring 7 will drive one end of the card rod 2 to re-engage in the threaded groove 3, and then the limit sleeve 12 is rotated, and then the limit sleeve 12 drives the clearance groove 8 to move. When the position of the clearance groove 8 corresponds to the position of the limit plate 11, the first push spring 16 is reset, and then the first push spring 16 pushes the control sleeve 5 to reset, so that the control sleeve 5 drives the limit frame 9 and the limit plate 11 to reset, and then the inner wall of the control sleeve 5 will limit the outside of the card rod 2 again, and at the same time, the second push spring 17 pushes the connecting rod 4, so that one end of the card rod 2 is close to the side wall of the threaded groove 3 to prevent the card rod 2 from moving, and at the same time, the insertion rod 15 set on one side of the control sleeve 5 will be inserted The control sleeve 5 is inserted into the socket 14 provided on the fixed plate 13, and then the control sleeve 5 is rotated. The control sleeve 5 will drive the fixed plate 13 to move through the insertion rod 15 and the socket 14, thereby driving the connecting sleeve 6 to move. Then the connecting sleeve 6 will drive the clamping rod 2 to move along the threaded groove 3, so that the connecting sleeve 6 and the connecting rod 4 cooperate to press the upper mold core 20 onto the upper mold base 18, and fasten the lower mold core 21 to the lower mold base 19. Then the limit sleeve 12 is rotated so that the position of the clearance groove 8 and the position of the limit plate 11 no longer correspond, so that the corresponding limit plate 11 and the limit sleeve 12 cooperate and form a limit on the control sleeve 5 through the limit frame 9 to prevent the control sleeve 5 from moving, thereby ensuring a fast and tight installation structure.

[0036] See also Figure 1 and Figure 3, as an implementation of the stamping device: The stamping device includes an upper die base 18, a lower die base 19, an upper die core 20, and a lower die core 21. The upper die base 18 is movably installed inside the machine tool 1, the lower die base 19 is detachably installed inside the machine tool 1, the upper die core 20 is detachably installed below the upper die base 18, and the lower die core 21 is detachably installed above the lower die base 19.

[0037] Sliding grooves 22 are provided on both the upper die base 18 and the lower die base 19, and mounting grooves 23 are symmetrically provided on both sides of the upper die core 20 and the lower die core 21.

[0038] A hydraulic cylinder 24 is provided at the top of the machine tool 1, a hydraulic rod 25 is provided at the output end of the hydraulic cylinder 24, and the bottom end of the hydraulic rod 25 is connected to the top end of the upper die base 18.

[0039] A slide rail 26 is provided inside the machine tool 1, and the upper die base 18 is slidably arranged inside the slide rail 26.

[0040] More specifically, when the device needs to be used, place the metal sheet above the lower die core 21, and then synchronously turn on the hydraulic cylinder 24. The hydraulic cylinder 24 drives the hydraulic rod 25 to drive the upper die base 18 and the upper die core 20 to descend, so that the upper die base 18 moves downward along the slide rail 26. The setting of the slide rail 26 ensures the stable movement of the upper die base 18. Then the upper die base 18 drives the upper die core 20 to close the die with the lower die core 21, thereby stamping the sheet, so that the sheet is stamped into shape. After stamping, the hydraulic cylinder 24 drives the hydraulic rod 25 to drive the upper die base 18 and the upper die core 20 to rise and reset. Then take out the sheet after stamping is completed, place a new metal sheet on the lower die core 21, and then continue the stamping and forming work according to the above steps. The settings of the sliding groove 22 and the mounting groove 23 facilitate the installation of the upper die core 20 and the lower die core 21.

[0041] In summary, when the overall device is in use or operation: when it is necessary to maintain or replace the upper die core 20 or the lower die core 21, first rotate the limit sleeve 12 in the corresponding direction. The limit sleeve 12 drives the relief groove 8 to move. Then, when the position of the relief groove 8 corresponds to the limit plate 11, push the control sleeve 5. The control sleeve 5 drives the limit frame 9 and the limit plate 11 to move, so that the limit frame 9 and the limit plate 11 pass through the relief groove 8. At the same time, the control sleeve 5 and the limit sleeve 12 cooperate to squeeze the first push spring 16. When the first push spring 16 is squeezed to the limit, the corresponding limit plate 11 just moves to one side of the limit sleeve 12. Then rotate the limit sleeve 12 so that the positions of the relief groove 8 and the limit plate 11 no longer correspond, so that the corresponding limit plate 11 is engaged with one side of the control sleeve 5 to prevent the control sleeve 5 from moving. At the same time, the outer side of the clamping rod 2 loses the limit of the inner wall of the control sleeve 5. Then pull the connecting sleeve 6 in the corresponding direction. The side wall of the thread groove 3 squeezes one end of the clamping rod 2. Since one end of the clamping rod 2 is designed with a rounded corner structure and the spring 7 only provides a weak restoring force, then the clamping rod 2 will be pushed out to the outside of the thread groove 3. At the same time, the clamping rod 2 drives the spring 7 to stretch. Then the connecting sleeve 6 can be removed. Then the upper die core 20 and the lower die core 21 can be removed. Then install the replaced upper die core 20 and lower die core 21 in the corresponding positions, and make the corresponding installation grooves 23 and the sliding grooves 22 correspond. Then pass the connecting rod 4 through the sliding groove 22 and the installation groove 23. Then sleeved the connecting sleeve 6 on the outside of the connecting rod 4. Then the spring 7 will drive one end of the clamping rod 2 to be re-engaged in the thread groove 3. Then rotate the limit sleeve 12. Then the limit sleeve 12 drives the relief groove 8 to move. When the position of the relief groove 8 corresponds to the position of the limit plate 11, the first push spring 16 resets. Then the first push spring 16 pushes the control sleeve 5 to reset, so that the control sleeve 5 drives the limit frame 9 and the limit plate 11 to reset. Then the inner wall of the control sleeve 5 will limit the outside of the clamping rod 2 again. At the same time, the second push spring 17 pushes the connecting rod 4, so that one end of the clamping rod 2 is close to the side wall of the thread groove 3 to prevent the clamping rod 2 from moving. At the same time, the insertion rod 15 arranged on one side of the control sleeve 5 will be inserted into the jack 14 opened on the fixing plate 13. Then rotate the control sleeve 5. The control sleeve 5 will drive the fixing plate 13 to move through the insertion rod 15 and the jack 14, so as to drive the connecting sleeve 6 to move. Then the connecting sleeve 6 will drive the clamping rod 2 to move along the thread groove 3, so that the connecting sleeve 6 and the connecting rod 4 cooperate to press the upper die core 20 onto the upper die base 18 and fasten the lower die core 21 to the lower die base 19. Then rotate the limit sleeve 12 so that the positions of the relief groove 8 and the limit plate 11 no longer correspond, so that the corresponding limit plate 11 and the limit sleeve 12 cooperate and form a limit on the control sleeve 5 through the limit frame 9 to prevent the control sleeve 5 from moving, thus ensuring a fast and firm installation structure.

[0042] When the device needs to be used, place the metal sheet above the lower die core 21, and then synchronously turn on the hydraulic cylinder 24. The hydraulic cylinder 24 drives the hydraulic rod 25 to drive the upper die base 18 and the upper die core 20 to descend, so that the upper die base 18 moves downward along the slide rail 26. The setting of the slide rail 26 ensures the smooth movement of the upper die base 18. Then the upper die base 18 drives the upper die core 20 to be closed with the lower die core 21, thereby stamping the sheet material to make the sheet material stamping and forming. After the stamping is completed, the hydraulic cylinder 24 drives the hydraulic rod 25 to drive the upper die base 18 and the upper die core 20 to rise and reset. Then take out the sheet material after stamping and forming, place a new metal sheet on the lower die core 21, and then continue the stamping and forming work according to the above steps. The settings of the sliding groove 22 and the installation groove 23 facilitate the installation of the upper die core 20 and the lower die core 21.
