Abstract
Description
Technical Field
[0001] This utility model relates to the field of die-cutting anti-overcutting technology, and in particular to a die-cutting limiting structure for preventing overcutting. Background Technology
[0002] A die is a special mold used for stamping and die cutting. It is usually made of steel blades embedded in a wooden board, rubber board or metal base. When using a die for die cutting, overcutting is easy to occur. In the existing technology, a support block of fixed length is usually set between the die and the mold base to limit the maximum movement distance of the die. However, with long-term processing, the support block is prone to wear, thereby reducing the die's ability to prevent overcutting. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies that only limit the maximum movement of the cutter using a support block, which reduces the ability to prevent overcutting after long-term use. Therefore, this invention proposes a die-cutting limiting structure to prevent overcutting.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] Design a die-cutting limiting structure to prevent overcutting, including a die base, a sliding rod slidably connected to the die base, a first auxiliary block fixedly connected to the side of the sliding rod, a locking block slidably connected to the sliding rod, several round rods slidably connected through the die base, a stop block fixedly connected to the end of each round rod, a first spring fixedly connected between the stop block and the die base, a movable ring fixedly connected between each round rod, a second auxiliary block fixedly connected to the side of each movable ring, the second auxiliary block slidably connected to the die base, an electric telescopic rod fixedly connected to the die base, a cutting element fixedly connected to the output end of the electric telescopic rod, and the cutting element engaging with the locking block.
[0006] Preferably, the cutting component includes a fixed frame, which is fixedly connected to the output end of the electric telescopic rod. A cutting blade is slidably connected inside the fixed frame. The bottom of the locking block abuts against the cutting blade, and the top of the locking block abuts against the fixed frame.
[0007] Preferably, a support ring is fixedly connected to the mold base, and a circular plate is fixedly connected to the surface of the support ring. An annular groove is formed between the circular plate and the mold base.
[0008] Preferably, the side of the first auxiliary block facing the circular plate is an inclined surface, and the side of the second auxiliary block facing the circular plate is an inclined surface, with the first auxiliary block and the second auxiliary block abutting against each other.
[0009] Preferably, an ear plate is fixedly connected to the surface of the mold base, and a second spring is fixedly connected between the ear plate and the slide rod.
[0010] Preferably, a limiting platform is fixedly connected to the surface of the mold base, and the limiting platform is slidably engaged with the slide rod.
[0011] Preferably, the moving ring and the cutter are arranged parallel to each other.
[0012] Preferably, the bottom of the cutter is annular, and the cutter corresponds to the annular groove.
[0013] The present invention proposes a die-cutting limiting structure for preventing overcutting. The beneficial effect is that when the cutter cuts downwards, if the moving distance exceeds the threshold, the cutter pushes the moving ring to move. The moving ring drives the second auxiliary block to push the first auxiliary block to move, thereby disengaging the locking block from the fixed frame and the cutter, releasing the limiting of the cutter, thereby releasing the cutting ability of the cutter and preventing the cutter from overcutting and damaging the die base.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Example 1
[0022] Reference Figure 1-4This utility model is a die-cutting limiting structure for preventing overcutting, including a die base 1, a sliding rod 2 slidably connected to the die base 1, a first auxiliary block 3 fixedly connected to the side of the sliding rod 2, a locking block 4 slidably connected to the sliding rod 2, a plurality of round rods 5 slidably connected through the die base 1, a stop block 6 fixedly connected to the end of the round rod 5, a first spring 7 fixedly connected between the stop block 6 and the die base 1, a moving ring 8 fixedly connected between each round rod 5, a second auxiliary block 9 fixedly connected to the side of the moving ring 8, the second auxiliary block 9 slidably connected to the die base 1, an electric telescopic rod 10 fixedly connected to the die base 1, a cutting element fixedly connected to the output end of the electric telescopic rod 10, and the cutting element and the locking block 4 being inserted into each other.
[0023] The cutting component includes a fixed frame 11, which is fixedly connected to the output end of the electric telescopic rod 10. A cutter 12 is slidably connected inside the fixed frame 11. The bottom of the locking block 4 abuts against the cutter 12, and the top of the locking block 4 abuts against the fixed frame 11. The side of the first auxiliary block 3 facing the circular plate 16 is inclined, and the side of the second auxiliary block 9 away from the circular plate 16 is inclined. The first auxiliary block 3 and the second auxiliary block 9 abut against each other.
[0024] The operation process of this embodiment is as follows: the plate to be processed is placed on the surface of the mold base 1, and the fixed frame 11 is moved downward by the electric telescopic rod 10. At this time, the locking block 4 is inserted between the fixed frame 11 and the cutter 12 to lock the two. That is, when the electric telescopic rod 10 moves the fixed frame 11 downward, the cutter 12 in the fixed frame 11 moves downward synchronously to die-cut the plate on the mold base 1.
[0025] To prevent overcutting during the die-cutting process, which could damage the cutter 12 or the die base 1, the first spring 7 continuously pushes the baffle and the round rod 5 upwards, maintaining a certain distance between the moving ring 8 and the die base 1. When the cutter 12 moves downwards beyond a predetermined value, i.e., after contacting the moving ring 8 again, it continues to move downwards, pushing the moving ring 8 downwards and stretching the first spring 7. The downward movement of the moving ring 8 causes the second auxiliary plate to move downwards. At this time, the second auxiliary plate pushes the first auxiliary plate to move to the right. The movement of the second auxiliary plate pushes the slide rod 2 and the locking block 4 to move to the right. Under normal circumstances, the locking block 4 is engaged. Between the fixed frame 11 and the cutter 12, when the fixed frame 11 moves downward, it can drive the cutter 12 to cut the bottom plate. At this time, as the locking block 4 moves to the right, the locking block 4 disengages from the fixed frame 11 and the cutter 12. When the electric telescopic rod 10 continues to push the fixed frame 11 downward, it can only push the fixed frame 11 to move. After the locking block 4 disengages, the cutter 12 does not have the ability to cut. After it abuts against the moving ring 8, it remains stationary and can cut downward. When the movement exceeds the threshold, the locking block 4 releases the limit on the cutter 12, thereby causing it to lose its cutting ability and avoiding damage to the cutter 12 and the die caused by over-cutting.
[0026] Example 2
[0027] After the retaining bracket 11 is reset, the locking block 4 needs to be re-engaged between the retaining bracket 11 and the cutter 12 to prevent over-cutting. This back-and-forth operation is rather cumbersome. Therefore, please refer to... Figure 1-3 Based on the first specific embodiment, a support ring 13 is fixedly connected to the mold base 1, a circular plate 16 is fixedly connected to the surface of the support ring 13, an annular groove 17 is provided between the circular plate 16 and the mold base 1, an ear plate 14 is fixedly connected to the surface of the mold base 1, a second spring 15 is fixedly connected between the ear plate 14 and the slide rod 2, a limiting platform is fixedly connected to the surface of the mold base 1, the limiting platform and the slide rod 2 are slidably engaged, the moving ring 8 and the cutter 12 are arranged parallel to each other, the bottom of the cutter 12 is annular, and the cutter 12 corresponds to the annular groove 17.
[0028] The operation process of this embodiment is as follows: The bottom of the cutter 12 is annular and corresponds to the annular groove 17. When performing die cutting, the board is placed on the surface of the mold base 1, and the cutter 12 moves downward to cut the board on the mold base 1. Since the annular groove 17 is provided between the mold base 1 and the circular plate 16, the cutter 12 can still move downward in the annular groove 17 after cutting the board, thereby avoiding damage to the mold base 1 when the cutter 12 cuts the board.
[0029] When the cutter 12 cuts through, the locking block 4 disengages from the fixed frame 11 and the cutter 12. The electric telescopic rod 10 then drives the fixed frame 11 to rise again. At this time, the fixed frame 11 drives the cutter 12 to reset. The second spring 15 continuously pushes the slide rod 2 to move to the left, keeping the first auxiliary block 3 and the second auxiliary block 9 in contact. When the cutter 12 disengages from the moving ring 8, the first auxiliary block 3 and the second auxiliary block 9 reset simultaneously. The reset of the second auxiliary block 9 drives the slide rod 2 and the locking block 4 to move to the left, so that the locking block 4 re-locks between the fixed frame 11 and the cutter 12, limiting its movement. When the fixed frame 11 continues to press down, the cutter 12 can still cut the plate. After contacting the locking block 4 for limiting, the fixed frame 11 rises and the locking block 4 resets, thus avoiding repeated pushing of the locking block 4 to reset it and improving work efficiency.
[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
