Description

Technical Field

[0001] This utility model relates to the field of cutting tools, and in particular to a precision die-cutting tool. Background Technology

[0002] Cutting tools are tools used for cutting and machining in mechanical manufacturing. The vast majority of cutting tools are machine-made, but some are hand-operated. Since cutting tools used in mechanical manufacturing are primarily for cutting metal materials, the term "cutting tool" is generally understood to refer to metal cutting tools.

[0003] A search revealed patent publication number CN218699625U, which discloses a precision die-cutting tool, comprising a tool body, a back blade, and a head blade. The back blade is located on one side of the tool body, and the head blade is connected to the top of the tool body. The other end of the tool body is connected to a transition head, which is disc-shaped. Reinforcing strips are connected to both sides of the connection between the tool body and the transition head, and a handle is connected to the other side of the transition head. The surface of the handle is decorated with anti-slip textures, and a limiting groove is provided at the other end of the handle. This utility model has a simple and reasonable structure, a novel design, and is easy and convenient to operate. It can effectively increase the cutting efficiency of the tool body and reduce the frequency of tool body replacement, thus possessing high practical value.

[0004] While existing technologies can fulfill certain cutting tool functions and meet the requirements of commonly used tools, they suffer from the following drawback: existing precision die-cutting tools lack the function of conveniently changing the cutting head. This leads to the cutting head being easily damaged when cutting some precision devices, or the need to change the cutting head repeatedly when processing devices of different sizes, which wastes a lot of time. In view of this, we propose a precision die-cutting tool that solves the above problems. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a precision die-cutting tool.

[0006] The technical solution of this utility model is as follows: A precision die-cutting tool includes a top cover, a rotating column, and a moving column. A rear cover is provided on one side of the top cover, and a rotating column is rotatably installed between the rear cover and the top cover. The rotating column has mounting grooves arranged in a circular array inside, and a moving column is inserted into the mounting groove. A mounting plate is fixed to the bottom of the moving column, and a fixing seat is fixed to one side of the mounting plate. An offset groove is provided on one side of the top cover, and the diameter of the groove is equal to the diameter of the moving column.

[0007] When using this device, it needs to be fixed to the machine tool using the mounting base and positioning holes. The device contains three types of cutting tools. During use, one tool can be selected. When the tool is in the ejected groove position, the limiting post is at its innermost position, and plane one and plane two are in contact. To switch tools, rotate the screw in the opposite direction, and the limiting post moves outward. As plane one and plane two gradually separate, the spring, along with the mounting plate, pulls the moving post back. Then, manually rotate the protrusion. During rotation, the spring stretches, and after the rotating post rotates 120 degrees inside the housing, the other cutting head faces the groove. After the spring returns, manually rotate the screw again, causing the limiting post to return to its innermost position, fixing the moving post's position. The other cutting head can then be used. This device features convenient precision cutting head switching, reducing unnecessary time wasted on cutting head changes and accelerating the work process.

[0008] Preferably, a guide rail is provided on one side of the inner wall of the top cover, the guide rail is connected to the groove, the part of the groove located on the inner side of the top cover is designed with rounded corners, and the part of the movable cylindrical surface that is in the groove is also designed with rounded corners.

[0009] Preferably, one end of the movable column is provided with a cutter head, which is fixed by rotation via a retainer.

[0010] Preferably, a spring is fixed to one side of the mounting plate, and the other side of the spring is fixedly connected to one side of the rotating column. The surface of the rotating column is provided with protrusions distributed in a ring array.

[0011] Preferably, a slot is provided on one side of the back cover, a limiting post is inserted into the slot, a limiting key is fixed at the upper end of the limiting post, a limiting groove is provided at the upper end of the inner wall of the slot, a rotating piece is fixed on one side of the limiting post, and a screw is rotatably installed on one side of the rotating piece, the screw passes through the slot and is threadedly connected to the slot.

[0012] Preferably, the limiting post has a second inclined surface on one side, a fixing seat on one side, an inclined surface on the side opposite to the limiting post, a flat surface on the top of the fixing seat, and a flat surface on the bottom of the limiting post.

[0013] Preferably, the top of the rear cover is fixed with a mounting base, and the mounting base has symmetrically arranged positioning holes inside.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] I. This utility model can install three precision cutting blades inside a rotating column inside the housing. When needed, simply rotate the rotating column, and with the spring force, you can initially switch between different blades inserted into the groove.

[0016] Second, based on the first beneficial effect, after the cutter head is inserted into the groove, the device needs to use the screw to rotate the limiting post to move inside the box. The cutter head is driven downward by the action of inclined plane one and inclined plane two until the plane one and plane two contact each other. Only then is the position of the cutter head perfectly fixed and will not wobble. At this time, the cutting work can be carried out smoothly.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0029] Example 1

[0030] Please see Figures 1-5 As shown, this embodiment is a precision die-cutting tool, including a top cover 1, a rotating column 12 and a moving column 13. A rear cover 23 is provided on one side of the top cover 1. The rotating column 12 is rotatably installed between the rear cover 23 and the top cover 1. The contact parts of the rotating column 12, the rear cover 23 and the top cover 1 are designed to fit together, so as to ensure the relative rotation effect of the rotating column 12. The rotating column 12 has a mounting groove 11 arranged in a ring array inside. The moving column 13 is inserted into the mounting groove 11. A mounting plate 9 is fixed at the bottom of the moving column 13. A fixing seat 16 is fixed on one side of the mounting plate 9. An offset groove 2 is provided on one side of the top cover 1. The diameter of the groove 2 is equal to the diameter of the moving column 13.

[0031] When using this device, it needs to be fixed to the machine tool using the mounting base 21 and positioning hole 22. The device is equipped with three types of cutting tools. When using it, one type of cutting tool can be selected for operation. When the cutting tool is in the position of ejecting from the groove 2, the limiting post 7 is in the innermost position. At this time, plane 19 and plane 2 17 are in contact. When it is necessary to switch cutting tools, turn the screw 4 in the opposite direction. The limiting post 7 moves outward. When the inclined plane 1 8 and inclined plane 2 18 gradually separate, the spring 10, along with the mounting plate 9, pulls the moving post 13 back. Then, manually turn the protrusion 3. During the rotation, the spring 10 is stretched. After the rotating post 12 rotates 120 degrees inside the top cover 1, the other cutting head 15 faces the groove 2. After the spring 10 rebounds, manually turn the screw 4 so that the limiting post 7 returns to the innermost position. The position of the moving post 13 is fixed, and the other cutting head 15 can be used for operation. This device has the function of convenient switching of precision cutting head 15, reducing the unnecessary time wasted in changing cutting head 15 during operation and speeding up the work progress.

[0032] Example 2

[0033] Please see Figures 1-5As shown, this embodiment, based on embodiment 1, further includes: a guide rail is provided on the inner wall of one side of the top cover 1, the guide rail is connected to the groove 2, the part of the groove 2 located inside the top cover 1 has a rounded corner design, and the part of the moving column 13 facing the groove 2 also has a rounded corner design. The guide rail is located inside the top cover 1, and its depth can be adapted to the length of the cutter head 15. The top of the guide rail can contact the top of the moving column 13. By using the design of rounded corners, the replacement of the cutter head 15 can be made smoother when rotating the rotating column 12.

[0034] The movable column 13 is provided with a cutter head 15 at one end. The cutter head 15 is fixed by rotating the retainer 14. The cutter head 15 is inserted into one end of the movable column 13, and then the retainer 14 is rotated to install and tighten it. This is a relatively traditional way of fixing the cutter head 15, and the details will not be described in detail.

[0035] A spring 10 is fixed to one side of the mounting plate 9, and the other side of the spring 10 is fixedly connected to one side of the rotating column 12. The surface of the rotating column 12 is provided with protrusions 3 arranged in a ring array. Under the action of the spring 10, the moving column where the cutter head 15 is located inside the top cover 1 will move backward. At this time, the spring 10 is in a stretched state. The spring 10 where the moving column 13 is inserted into the groove 2 is in a normal state. Under normal state, the moving column 13 where the spring 10 is located will insert a certain distance into the groove 2. This can ensure that when the operator rotates the rotating column 12, the cutter head 15 can move smoothly a certain distance outside the groove 2. Then, the fixed seat 16 and the limiting column 7 at the rear end are used to achieve a stable fixing effect.

[0036] A slot 20 is provided on one side of the back cover 23. A limit post 7 is inserted into the slot 20. A limit key 6 is fixed at the upper end of the limit post 7. A limit groove is provided at the upper end of the inner wall of the slot 20. A rotating piece 5 is fixed on one side of the limit post 7. A screw 4 is rotatably installed on one side of the rotating piece 5. The screw 4 passes through the slot 20 and is threadedly connected to the slot 20. The limit post 7 can move laterally inside the slot 20 by rotating the screw 4. The design of the limit key 6 and the limit groove can ensure that the limit post 7 will not rotate, ensuring the maximum area of ​​the inclined surface 1 8 and the inclined surface 2 18 fits together.

[0037] The limiting post 7 has a second inclined surface 18 on one side and a fixed seat 16 on the other side. The fixed seat 16 has an inclined surface 8 on the opposite side of the limiting post 7. The top of the fixed seat 16 has a flat surface 19, and the lower end of the limiting post 7 has a flat surface 17. The design of the inclined surface 8 and the second inclined surface 18 can drive the longitudinal movement of the fixed seat 16 by the lateral movement of the limiting post 7, so as to fix the cutter head 15 after it is inserted into the groove 2. After the cutter head 15 is inserted into the groove 2, the screw 4 is rotated to the lowest end so that the flat surface 19 and the flat surface 17 are in contact. At this time, the inclined surface 8 and the second inclined surface 18 are disengaged. Rotating the screw 4 further inward will not push the cutter head 15 to move. At this time, it can be ensured that the cutter head 15 has moved to the limit position and can participate in the cutting work.

[0038] The top of the rear cover 23 is fixed with a mounting base 21. The mounting base 21 has symmetrically arranged positioning holes 22 inside. The mounting base 21, together with the positioning holes 22, can achieve the effect of fixing the device so that it can be installed in the corresponding part of the machine tool.
