Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to a quick die-changing device for facilitating the positioning of stamping dies. Background Technology

[0002] When installing and using stamping dies, the dies need to be fixed on the worktable. In existing technology, dies are generally clamped using a die clamp. Chinese patent application number 202322145058.2 discloses a hydraulic die clamp for die changing, including an L-shaped sleeve bracket. A guide shaft is fixedly connected to the inner wall of the L-shaped sleeve bracket, and a rotating clamping block is rotatably connected to the outer wall of the guide shaft. A guide rectangular hole is provided on the inner wall of the L-shaped sleeve bracket, located below the rotating clamping block. A splitting mechanism is installed inside the guide rectangular hole. The splitting mechanism includes a linkage screw disposed inside the guide rectangular hole, a sleeve support block slidably connected to the guide rectangular hole on the outer wall of the linkage screw, a linkage slide plate connected to one side of the sleeve support block, and a sleeve disassembly plate and an inclined bracket arranged sequentially from right to left above the linkage slide plate. The patent document's design for disassembling and assembling the rotating clamping block is not convenient enough. Furthermore, because the support base is fixedly welded to a designated track, the position of the rotating clamping block is not adjustable, making it unsuitable for clamping molds of different sizes. Therefore, the shortcomings are quite obvious, and a solution is urgently needed. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a quick mold changing device that facilitates the positioning of stamping dies.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A quick die-changing device for easy positioning of stamping dies includes a base, a slide block slidably connected to the top surface of the base, a moving drive mechanism mounted on the base and used to drive the slide block to reciprocate, two support plates arranged parallel to both sides of the front end of the slide block, a clamping driver mounted on the slide block, a detachable insert shaft horizontally penetrating the two support plates, a clamping block detachably disposed between the two support plates, and a clamping limiting mechanism disposed on the slide block and used to engage with both ends of the insert shaft. The middle part of the clamping block is detachably rotatably connected to the insert shaft, one end of the clamping block extends out of the two support plates, and the other end of the clamping block is hinged to the drive end of the clamping driver via a locking assembly.

[0006] Furthermore, the support plate has a through hole, and the middle of the clamping block has a rotating hole for coaxial communication with the through hole, through which the insertion shaft passes.

[0007] Furthermore, the locking assembly includes a sleeve, a locking bolt, and a nut. The sleeve is located at the drive end of the clamping driver. Two hinged ears are arranged parallel to each other at the end of the clamping block. The sleeve is located between the two hinged ears. The hinged ears have hinged holes coaxial with the sleeve. The screw of the locking bolt passes through the sleeve and the hinged holes of the two hinged ears and is threadedly connected to the nut.

[0008] Furthermore, both ends of the insert shaft are recessed with slots, and the locking end of the locking and limiting mechanism is used to lock into the slots.

[0009] Furthermore, the locking and limiting mechanism includes two locking and limiting components symmetrically arranged on both sides of the slide, which are used to lock with both ends of the insert shaft.

[0010] Furthermore, the snap-fit ​​limiting assembly includes a fixed plate disposed on one side of the slide block, a guide rod horizontally mounted on the fixed plate, a limiting plate disposed on the free end of the guide rod, a sliding plate slidably sleeved on the guide rod, a snap-fit ​​limiting arm connected to the sliding plate, and an elastic element elastically disposed between the sliding plate and the fixed plate. The snap-fit ​​limiting arm is used to snap-fit ​​with the end of the insert shaft, and the sliding plate is located between the limiting plate and the fixed plate.

[0011] Furthermore, the elastic element is a spring, which is sleeved on the outside of the guide rod.

[0012] Furthermore, the top surface of the base is recessed with a groove, and the bottom surface of the slide is protruded with a slider, which is slidably disposed within the groove.

[0013] Furthermore, a guide frame is installed inside the chute, and the slider is slidably connected to the guide frame.

[0014] Furthermore, support blocks are provided on both sides of the slide, and the bottom surface of the locking and limiting arm is slidably connected to the top surface of the support block.

[0015] The beneficial effects of this utility model are as follows: In practical applications, the stamping die is placed on the base. The moving drive mechanism drives the slide block, along with the clamping driver, the locking and limiting mechanism, and the clamping block, to move closer to the stamping die until the end of the clamping block is above the lower die holder of the stamping die. Then, the clamping driver drives the clamping block to rotate around the insertion shaft, so that the clamping block clamps and positions the lower die holder of the stamping die on the base. When it is necessary to change the stamping die, the clamping driver drives the clamping block to rotate in the opposite direction around the insertion shaft, so that the clamping block releases the stamping die. Then, the moving drive mechanism drives the slide block to move closer to the base. The clamping driver, locking and limiting mechanism, and clamping block are moved away from the stamping die, allowing for die replacement. When the clamping block needs replacement, the locking assembly is first disassembled, then the locking and limiting mechanism is used to release the insert shaft, allowing it to be pulled away from the clamping block and the two support plates. The old clamping block can then be removed and replaced with a new one. The insert shaft passes through the middle of the new clamping block and the two support plates. The locking and limiting mechanism engages both ends of the insert shaft. The locking assembly then locks the end of the clamping block to the drive end of the clamping driver, making the end of the clamping block hinged to the drive end of the clamping driver. This invention allows for adjustment of the clamping block's position to clamp and position stamping dies of different specifications, and the clamping block is easy to disassemble and replace.

[0021] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0022] like Figures 1 to 3As shown, the present invention provides a quick mold changing device for easy positioning of stamping dies, which includes a base 1, a slide 2 slidably connected to the top surface of the base 1, a moving drive mechanism 3 mounted on the base 1 and used to drive the slide 2 to reciprocate, two support plates 4 parallel to the front end sides of the slide 2, a clamping driver 5 mounted on the slide 2, a detachable horizontal insertion shaft 6 passing through the two support plates 4, a clamping block 7 detachably disposed between the two support plates 4, and a clamping limiting mechanism 8 disposed on the slide 2 and used to clamp the two ends of the insertion shaft 6. The middle part of the clamping block 7 is detachably rotatably connected to the insertion shaft 6, one end of the clamping block 7 extends out of the two support plates 4, and the other end of the clamping block 7 is hinged to the driving end of the clamping driver 5 via a locking component 9.

[0023] In practical applications, the base 1 is mounted on the workbench, and the stamping die 28 is placed on the base 1. The moving drive mechanism 3 drives the slide 2, along with the clamping drive 5, the locking and limiting mechanism 8, and the clamping block 7, to move closer to the stamping die 28 until the end of the clamping block 7 is above the lower die base of the stamping die 28. Then, the clamping drive 5 drives the clamping block 7 to rotate around the insertion shaft 6, so that the clamping block 7 clamps and positions the lower die base of the stamping die 28 on the base 1. When it is necessary to replace the stamping die 28, the clamping drive 5 drives the clamping block 7 to rotate in the opposite direction around the insertion shaft 6, so that the clamping block 7 releases the stamping die 28. Then, the moving drive mechanism 3 drives the slide 2 to move closer to the stamping die 28. The clamping driver 5, the locking and limiting mechanism 8, and the clamping block 7 move away from the stamping die 28, allowing the stamping die 28 to be replaced. When the clamping block 7 needs to be replaced, first disassemble the locking assembly 9, then release the insert shaft 6 through the locking and limiting mechanism 8, allowing the insert shaft 6 to be pulled away from the clamping block 7 and the two support plates 4. At this point, the old clamping block 7 can be removed and replaced with a new clamping block 7. The insert shaft 6 passes through the middle of the new clamping block 7 and the two support plates 4. The locking and limiting mechanism 8 locks the two ends of the insert shaft 6. Then, the locking assembly 9 locks the end of the clamping block 7 to the driving end of the clamping driver 5, making the end of the clamping block 7 hinged to the driving end of the clamping driver 5. This utility model can adjust the position of the clamping block 7 to meet the clamping and positioning of stamping dies 28 of different specifications, and the disassembly and replacement of the clamping block 7 are convenient.

[0024] In this embodiment, the support plate 4 has a through hole, and the clamping block 7 has a rotating hole in the middle for coaxial communication with the through hole. The insertion shaft 6 passes through the through hole and the rotating hole. This structural design facilitates the assembly and disassembly of the insertion shaft 6.

[0025] In this embodiment, the locking assembly 9 includes a sleeve 11, a locking bolt 12, and a nut 13. The sleeve 11 is disposed at the drive end of the clamping driver 5. Two hinge ears 14 are arranged parallel to each other at the end of the clamping block 7. The sleeve 11 is located between the two hinge ears 14. The hinge ears 14 have hinge holes coaxial with the sleeve 11. The thread of the locking bolt 12 passes through the hinge holes of the sleeve 11 and the two hinge ears 14 and is threadedly connected to the nut 13. This structural design facilitates the disassembly and assembly of the locking assembly 9, and also facilitates the hinge connection between the clamping block 7 and the drive end of the clamping driver 5.

[0026] In this embodiment, both ends of the insertion shaft 6 are recessed with slots 15, and the locking end of the locking and limiting mechanism 8 is used to lock with the slots 15. When the two locking and limiting ends of the locking and limiting mechanism 8 are respectively locked with the two slots 15 of the insertion shaft 6, the insertion shaft 6 will not detach from the support plate 4, thus improving the working stability of the clamping block 7.

[0027] In this embodiment, the locking and limiting mechanism 8 includes two locking and limiting components 16 symmetrically arranged on both sides of the slide block 2. The two locking and limiting components 16 are used to lock with both ends of the insertion shaft 6. Specifically, the locking and limiting component 16 includes a fixed plate 17 disposed on one side of the slide block 2, a guide rod 18 horizontally mounted on the fixed plate 17, a limiting plate disposed on the free end of the guide rod 18, a sliding plate 20 slidably sleeved on the guide rod 18, a locking and limiting arm 21 connected to the sliding plate 20, and an elastic member 22 elastically disposed between the sliding plate 20 and the fixed plate 17. The locking and limiting arm 21 is used to lock with the end of the insertion shaft 6, and the sliding plate 20 is located between the limiting plate and the fixed plate 17. In practical applications, the elastic force of the elastic element 22 drives the locking arm 21 to be stably locked together with the slot 15 of the insert shaft 6 via the slide plate 20. When it is necessary to release the insert shaft 6, a force that overcomes the elastic element 22 is applied to the slide plate 20 and / or the locking arm 21, causing the slide plate 20 and the locking arm 21 to move away from the insert shaft 6 along the guide rod 18, thereby separating the locking arm 21 from the insert shaft 6. At this time, the insert shaft 6 can be pulled out from the support plate 4 and the clamping block 7.

[0028] In this embodiment, the elastic element 22 is a spring, which is sleeved on the guide rod 18. The guide rod 18 guides and positions the spring, improving its working stability and facilitating its assembly and disassembly.

[0029] In this embodiment, the top surface of the base 1 is recessed with a groove 23, and the bottom surface of the slide block 2 is protruded with a slider 24, which is slidably disposed within the groove 23. During the sliding process of the slide block 2 relative to the base 1, the slider 24 slides in conjunction with the groove 23, thereby improving the stability of the reciprocating movement of the slide block 2.

[0030] In this embodiment, a guide frame 25 is installed inside the slide groove 23, and the slider 24 is slidably connected to the guide frame 25. By adding the guide frame 25, the slider 24 is prevented from directly contacting the inner wall of the slide groove 23, reducing the wear of the slide groove 23. When the guide frame 25 is worn, only the guide frame 25 needs to be replaced, reducing maintenance costs.

[0031] In this embodiment, support blocks 26 are provided on both sides of the slide block 2, and the bottom surface of the locking and limiting arm 21 is slidably connected to the top surface of the support block 26. In practical applications, the support blocks 26 provide support for the locking and limiting arm 21 and improve the stability of the reciprocating movement of the locking and limiting arm 21.

[0032] Specifically, the clamping driver 5 is a hydraulic cylinder.

[0033] Specifically, the slide 2 is provided with a cover plate 27, which covers the top port of the slide groove 23. By covering the top port of the slide groove 23 with the cover plate 27, it is possible to prevent dust and other debris from falling or accumulating in the slide groove 23.

[0034] All technical features in this embodiment can be freely combined according to actual needs.

[0035] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
