Description

Technical Field

[0001] The utility model relates to the technical field of bending punches, in particular to a bending punch. Background Art

[0002] A bending punch is a tool used in metal processing, typically used to stamp and bend metal sheets to create parts or products of specific shapes. They are usually made of carbide or other high-strength materials to withstand high pressure and frequent use. The design of the bending punch can be adjusted according to the required shape and size of the finished product, thereby ensuring precise forming and processing during the manufacturing process.

[0003] The existing patent (publication number: CN204914548U) proposes a bending punch and stamping equipment, wherein the bending punch includes a punch body; the punch body includes a stamping surface facing the frame; the stamping surface includes a contact surface and a crimping surface; the contact surface is perpendicular to the stamping direction of the punch body, and the crimping surface is set at an obtuse angle to the contact surface.

[0004] The punch body is provided with a clearance groove between the abutting surface and the pressing surface; the abutting surface abuts the frame body to compress the frame body, and the pressing surface abuts the strap to bend the strap. The frame punched by the bending punch of the utility model can avoid cracks caused by local structural damage.

[0005] However, in actual use, the following deficiencies still exist, for example: the existing bending punch cannot detect whether the bottom of the bending punch is damaged. Damage to the bottom of the punch may cause uneven bending force, thereby affecting the bending angle and dimensional accuracy of the product. The damaged punch may leave scratches or indentations on the material surface, affecting the appearance quality of the product. The damaged punch needs to be frequently inspected and replaced, which increases downtime and reduces production efficiency. Punch damage may cause an increase in the material scrap rate during the bending process, requiring more material investment. Therefore, the utility model proposes a bending punch to solve the above problems. Utility Model Content

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a bending punch, comprising a bending punch, a detection component is provided on the bending punch, a quick-release component is provided on the top side of the bending punch, and a heat dissipation component is provided on the bottom side of the bending punch;

[0008] The detection assembly includes a first support plate and a slide groove, a slider is fixed on the first support plate, the slider is slidably connected in the slide groove, a second support plate is rotatably connected to the first support plate, a limiting groove is provided on the first support plate, a first limiting column is fixed on the second support plate, the second support plate is fixed in the limiting groove, and a damping rod is provided on the second support plate.

[0009] As a preferred embodiment, the first support plate is slidably connected to the bending punch, and the sliding groove is provided on the bending punch.

[0010] The beneficial effect of adopting the above-mentioned further scheme is: since the first support plate is slidably connected to the bending punch, the detection component as a whole can be connected to the bending punch, and since the slide groove is opened on the bending punch, the slider fixed on the first support plate can be slidably connected in the slide groove opened on the bending punch.

[0011] As a preferred embodiment, a clamping block is rotatably connected to the first support plate, a clamping seat is fixed on a side of the bending punch close to the clamping block, and the clamping block is fixed in the clamping seat.

[0013] As a preferred embodiment, the quick-release assembly includes a second limiting column, which is slidably connected in the bending punch. A fixing seat is fixed on the second limiting column, and a moving block is slidably connected in the fixing seat.

[0017] As a preferred embodiment, the heat dissipation component includes a copper plate and heat dissipation holes, the copper plate is fixed on the bending punch, the heat dissipation holes are opened on the bending punch, and heat dissipation fins are fixed on the copper plate.

[0018] The beneficial effect of adopting the above-mentioned further scheme is: since the bending punch is provided with heat dissipation holes, the heat dissipation area can be increased and the heat dissipation efficiency can be improved. Through the cooperation of the copper plate and the heat dissipation fins, the copper plate can conduct the heat inside the bending punch to the heat dissipation fins, and the heat on the bending punch can be dissipated faster.

[0019] Compared with the prior art, the advantages and positive effects of the present invention are:

[0020] In the present invention, the operator removes the card block from the card seat and moves the first support plate downward, so that the first support plate drives the second support plate to move downward together. When the second support plate moves down to a certain position, the first limit column is removed from the limit groove, so that the second support plate is released from the fixation on the first support plate, and then the second support plate is pulled upward so that the damping rod provided on the second support plate contacts the bottom of the bending punch. The bending punch presses the damping rod so that the damping rod can print the bottom outline of the bending punch. By observing the flatness of the damping rod, it is possible to check whether the bottom of the bending punch is damaged, thereby solving the technical problem of whether the bending punch is damaged and whether it affects the bending work.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] like Figure 1-Figure 4 As shown, this embodiment provides a technical solution: a bending punch, comprising a bending punch 1, a detection component 2 is provided on the bending punch 1, a quick release component 3 is provided on the top side of the bending punch 1, and a heat dissipation component 4 is provided on the bottom side of the bending punch 1;

[0032] like Figure 1-Figure 2 As shown, the detection assembly 2 includes a first support plate 21 and a slide groove 23, a slider 22 is fixed on the first support plate 21, the slider 22 is slidably connected in the slide groove 23, and the first support plate 21 is rotatably connected to the second support plate 24, a limiting groove 25 is provided on the first support plate 21, a first limiting column 26 is fixed on the second support plate 24, the second support plate 24 is fixed in the limiting groove 25, and a damping rod 27 is provided on the second support plate 24. During operation, the block 28 is first removed from the base 29 to allow the first support plate 21 to move freely, and then the first support plate 21 is moved downward. Since the first support plate 21 is connected to the second support plate 24, the second support plate 24 will also move downward. When the second support plate 24 moves down to the appropriate position, the first limiting column 26 is removed from the limiting groove 25 to release the fixation of the second support plate 24. Then, the second support plate 24 is pulled upward so that the damping rod 27 on it contacts the bottom of the bending punch 1. The bending punch 1 presses the damping rod 27, so that the damping rod 27 can print the bottom outline of the bending punch 1. By observing the flatness of the damping rod 27, it can be judged whether the bottom of the bending punch 1 is damaged. If the surface of the damping rod 27 is flat, it means that the bottom of the bending punch 1 is not damaged; if the surface of the damping rod 27 is uneven, it means that the bottom of the bending punch 1 may be damaged, thereby solving the technical problem of whether the bending punch 1 is damaged and whether it affects the bending work.

[0033] The above solutions still have the problem that the bending punch 1 cannot meet the heat dissipation requirements when bending the workpiece and the bending punch 1 cannot be quickly disassembled after being damaged. Figure 1-Figure 2As shown: the first support plate 21 is slidably connected to the bending punch 1, and the slide groove 23 is provided on the bending punch 1. Since the first support plate 21 is slidably connected to the bending punch 1, the detection assembly 2 can be connected to the bending punch 1 as a whole. Since the slide groove 23 is provided on the bending punch 1, the slider 22 fixed on the first support plate 21 can be slidably connected in the slide groove 23 provided on the bending punch 1. The first support plate 21 is rotatably connected to the clamping block 28, and the side of the bending punch 1 close to the clamping block 28 is fixed with a clamping seat 29, and the clamping block 28 is fixed in the clamping seat 29. Since the first support plate 21 is rotatably connected to the clamping block 28, the side of the bending punch 1 close to the clamping block 28 is fixed with a clamping seat 29, and the clamping block 28 is fixed in the clamping seat 29, so that the first support plate 21 can be fixed on the bending punch 1, preventing the detection assembly 2 from moving as a whole and affecting the bending work during the bending punch 1 bending operation;

[0034] like Figure 1 as well as Figure 3 As shown, the quick-release assembly 3 includes a second limiting post 31, which is slidably connected to the bending punch 1, and a fixed seat 32 is fixed on the second limiting post 31, and a moving block 33 is slidably connected to the fixed seat 32. The operator rotates the knob 36, and the knob 36 drives the rotating block 35 and the rotating rod 34 to rotate, so that the rotating rod 34 can move in the moving block 33, so that the moving block 33 rotates, and the rotating rod 34 is slidably connected to the moving block 33, and the rotating rod 34 is rotatably connected to the rotating block 35, and the rotating knob 36 is fixed on the rotating block 35, and the rotating knob 36 is rotatably connected to the bending punch 1. Due to the rotation of the moving block 33, the moving block 33 can drive the fixed seat 32 and the second limiting post 31 to move outside the bending punch 1, so that the part of the second limiting post 31 extending outside the bending punch 1 can be fixed to the stamping equipment;

[0035] like Figure 1 as well as Figure 4 As shown, the heat dissipation component 4 includes a copper plate 41 and a heat dissipation hole 43. The copper plate 41 is fixed on the bending punch 1. The heat dissipation hole 43 is opened on the bending punch 1. The heat dissipation fins 42 are fixed on the copper plate 41. Since the heat dissipation holes 43 are opened on the bending punch 1, the heat dissipation area can be increased and the heat dissipation efficiency can be improved. Through the cooperation of the copper plate 41 and the heat dissipation fins 42, the copper plate 41 can conduct the heat inside the bending punch 1 to the heat dissipation fins 42, and the heat on the bending punch 1 can be dissipated faster.

[0036] Working principle:

[0037] like Figure 1-Figure 4As shown, during the operation, the block 28 is first removed from the holder 29 so that the first support plate 21 can move freely, and then the first support plate 21 is moved downward. Since the first support plate 21 is connected to the second support plate 24, the second support plate 24 will also move downward. When the second support plate 24 moves down to the appropriate position, the first limiting column 26 is removed from the limiting groove 25 to release the fixation of the second support plate 24. Subsequently, the second support plate 24 is pulled upward so that the damping rod 27 on it contacts the bottom of the bending punch 1. The bending punch 1 presses the damping rod 27 so that the damping rod 27 can print the bottom outline of the bending punch 1. By observing the flatness of the damping rod 27, it can be judged whether the bottom of the bending punch 1 is damaged. If the surface of the damping rod 27 is flat, it means that the bottom of the bending punch 1 is not damaged; if the surface of the damping rod 27 is uneven If the bending punch 1 is damaged, the bottom of the bending punch 1 may be damaged. When the bending punch 1 is damaged, turn the knob 36 of the new bending punch 1. The knob 36 drives the rotating block 35 and the rotating rod 34 to rotate, so that the rotating rod 34 can move in the moving block 33, so that the moving block 33 rotates. Due to the rotation of the moving block 33, the moving block 33 can drive the fixed seat 32 and the second limiting column 31 to move outside the bending punch 1, so that the part of the second limiting column 31 extending outside the bending punch 1 can be fixed on the stamping equipment. Since the bending punch 1 is provided with a heat dissipation hole 43, the heat dissipation area can be increased and the heat dissipation efficiency is improved. Through the cooperation of the copper plate 41 and the heat dissipation fins 42, the copper plate 41 can conduct the heat inside the bending punch 1 to the heat dissipation fins 42, so that the heat on the bending punch 1 can be dissipated faster.

[0038] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
