Description

Technical Field

[0001] The utility model relates to the technical field of punching and cutting, in particular to a punching and cutting component. Background Art

[0002] Commutator copper bars are usually manufactured by punching. During the punching process, due to the open design of the punching station, after the punch punches down the waste, it is easy to bring the waste out of the station during the return process, so that the waste enters the punching die and affects the feeding, resulting in the copper bars of different lengths or failure to feed, affecting product quality and production efficiency. Utility Model Content

[0003] In view of this, the utility model provides a blanking assembly to solve the problem that the punch easily carries waste out of the workstation during the return process, causing the waste to enter the inside of the blanking die and affect the feeding, resulting in copper bars of different lengths or failure to feed, affecting product quality and production efficiency.

[0004] In order to solve the above problems, the utility model provides a punching assembly, comprising:

[0005] The punching die is arranged on one side of the punching punch, and the punching die has a hollow punching station. The top and bottom of the punching station are respectively provided with at least one limiting structure. There is a gap between the limiting structure arranged at the top and the limiting structure arranged at the bottom. The punching material is arranged in the gap, and the limiting structures are respectively abutted against the upper and lower end surfaces of the punching material.

[0006] Beneficial effect: By setting a limiting structure at the top and bottom of the punching station, the limiting structure abuts against the upper and lower end surfaces of the punching material. When the punching punch punches the material in the punching station, waste will be generated at the upper and lower ends of the punching material. The limiting structure can limit the waste generated by the punching within the gap, preventing the waste from entering the inside of the punching die with the return stroke of the punching punch and affecting the feeding, thereby effectively ensuring product quality and production efficiency.

[0007] In an optional embodiment, the shearing punch is provided with a clearance structure matching the outer contour of the limiting structure, and the clearance structure avoids the limiting structure.

[0008] Beneficial effect: By setting the yield structure, the punching punch can avoid the limiting structure during the punching process, thereby preventing the punching punch from colliding with the limiting structure and causing damage to the punching punch and the limiting structure.

[0009] In an optional embodiment, a side of the punching station away from the punching punch is a waste outlet, and the limiting structure is suitable for guiding the waste punched by the punching punch to the waste outlet for discharge.

[0010] Beneficial effects: During the blanking process, the blanking punch will blank waste on the upper and lower end faces of the blanking material. The waste will be pushed by the blanking punch and move towards the waste outlet. The limiting structure abuts against the waste, which can limit and guide the waste.

[0011] In an optional embodiment, a contacting structure is arranged horizontally within the blanking station. The contacting structure is located between the gaps, and both sides of the contacting structure are fixedly connected to the left and right side faces of the blanking station respectively, so that the contacting structure abuts against the side face of the blanking material away from the blanking punch.

[0012] Beneficial effects: The contacting structure can provide a lateral supporting force to the blanking material to prevent the blanking punch from breaking the blanking material. At the same time, the contacting structure can also limit the blanked product.

[0013] In an optional embodiment, a slideway extending horizontally is arranged on the side face of the blanking die facing the blanking punch. The slideway is located on both sides of the blanking station, and the blanking material is movably arranged within the slideway.

[0014] Beneficial effects: The blanking material can enter the blanking station through the slideway, achieving the effect of continuous feeding, which is beneficial to improving production efficiency.

[0015] In an optional embodiment, both sides of the contacting structure are respectively connected to the slideways on both sides, and the side face of the contacting structure facing the blanking material and the side face of the slideway parallel to the gravity direction are located in the same plane.

[0016] In an optional embodiment, the end of the limiting structure abutting against the blanking material has an arc surface.

[0017] In an optional embodiment, the cross-section of the limiting structure is triangular, and the angle of the triangle facing the blanking material is rounded. Description of the Drawings

[0028] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0029] like Figures 1 to 4As shown, this embodiment discloses a blanking assembly, including: a blanking die 1. The blanking die 1 is arranged on one side of a blanking punch 2, and the blanking die 1 has a hollow blanking station 3, and at least one limiting structure 4 is respectively arranged at the top and the bottom of the blanking station 3, and there is a gap between the limiting structure 4 arranged at the top and the limiting structure 4 arranged at the bottom, and a blanking material 5 is arranged in the gap, and the limiting structure 4 abuts against the upper and lower end surfaces of the blanking material 5 respectively.

[0030] Specifically, the punching die 1 is provided with a rectangular hollow punching station 3, and a limiting structure 4 is arranged on the top and bottom surfaces of the punching station 3. In the present embodiment, the limiting structures 4 on the top and bottom surfaces are arranged relative to each other. In other embodiments, the limiting structures 4 on the top and bottom surfaces may not be arranged relative to each other. The limiting structures 4 on the top and bottom surfaces are respectively abutted against the upper and lower end surfaces of the punching material 5 arranged in the punching station 3, and the punching punch 2 is arranged relative to the punching station 3. The punching punch 2 can move toward the punching station 3 and punch the punching material 5 in the punching station 3. Waste will be generated at the upper and lower ends of the punching material 5 during punching, and the limiting structure 4 will abut against the waste and limit the waste.

[0031] In this embodiment, the punching assembly of the present application can limit the waste generated by punching through the limiting structure 4 during punching, thereby effectively preventing the waste from entering the punching die during the return stroke of the punching punch 2 and affecting the feeding, causing product quality problems.

[0032] Preferably, in the present embodiment, a limiting structure 4 is respectively provided at the top and the bottom of the punching station 3. In other optional embodiments, two, three or other numbers of limiting structures 4 may be respectively provided at the top and the bottom of the punching station 3.

[0033] like Figure 3 As shown, in some embodiments, the punching punch 2 is provided with a clearance structure 6 matching the outer contour of the limiting structure 4, and the clearance structure 6 avoids the limiting structure 4. The clearance structure 6 allows the punching punch 2 to avoid the limiting structure 4 during the punching process, thereby preventing the punching punch 2 from colliding with the limiting structure 4 and causing damage to the punching punch 2 and the limiting structure 4.

[0034] like Figures 1 to 4 As shown, in some embodiments, the side of the punching station 3 away from the punching punch 2 (not shown) is a waste outlet, and the limiting structure 4 is suitable for guiding the waste punched by the punching punch 2 to the waste outlet and discharge it.

[0035] In this embodiment, the side of the blanking station 3 facing the blanking punch 2 is the blanking opening, and the side of the blanking station 3 away from the blanking punch 2 is the waste outlet. During the blanking process, the blanking punch 2 will extend into the blanking opening and punch out waste on the upper and lower end faces of the blanking material 5. The waste will be pushed by the blanking punch 2 towards the waste outlet. The limiting structure 4 abuts against the waste, which can limit and guide the waste and guide the waste to be discharged from the waste outlet.

[0036] As Figures 1 to 4 shown, in some embodiments, a contacting structure 7 is provided in the blanking station 3 and arranged horizontally. The contacting structure 7 is located between the gaps, and both sides of the contacting structure 7 are fixedly connected to the left and right side faces of the blanking station 3 respectively so that the contacting structure 7 abuts against the side face of the blanking material 5 away from the blanking punch 2.

[0037] In this embodiment, the contacting structure 7 is arranged in the blanking station 3. The left and right sides of the contacting structure 7 are fixedly connected to the left and right side faces of the blanking station 3 respectively. The side face of the contacting structure 7 facing the blanking punch 2 abuts against the blanking material 5. The contacting structure 7 can provide a lateral supporting force to the blanking material 5, improve the strength of the blanking material 5, and prevent the blanking material 5 from being broken due to excessive force during the blanking process. After the blanking is completed, it can be used to support the product after blanking.

[0038] As Figures 1 to 3 shown, in some embodiments, a slideway 8 extending horizontally is provided on the side face of the blanking die 1 facing the blanking punch 2. The slideway 8 is located on both sides of the blanking station 3, and the blanking material 5 is movably arranged in the slideway 8.

[0039] As Figures 1 to 3 shown, in some embodiments, both sides of the contacting structure 7 are connected to the slideways 8 on both sides respectively. The side face of the contacting structure 7 facing the blanking material 5 and the side face of the slideway 8 parallel to the gravity direction are located in the same plane.

[0040] In this embodiment, a slideway 8 extending horizontally is provided on the side face of the blanking die 1 facing the blanking punch 2. The slideway 8 is located on both sides of the blanking station 3. The side face of the contacting structure 7 abutting against the blanking material 5 and the side face of the slideway 8 parallel to the gravity direction are located in the same plane, which can avoid a height difference between the contacting structure 7 and the slideway 8 and cause the blanking material 5 to be broken during the blanking process.

[0041] In some embodiments, the end of the limiting structure 4 abutting against the blanking material 5 has a circular arc surface.

[0042] As Figure 1 or Figure 2 shown, in some embodiments, the cross-section of the limiting structure 4 is triangular, and the angle of the triangle facing the blanking material 5 is rounded.

[0043] In this embodiment, the cross-section of the limiting structure 4 is triangular, and the angle of the triangle facing the punching material 5 is a rounded corner, which can reduce the friction force and prevent the waste material from being unable to move due to excessive friction force.

[0044] Specifically, the limiting structure 4 can also be set as a cylinder, and one end of the cylinder facing the punching material 5 has an arc surface, or it can also be set as a regular hexahedron, and one surface of the regular hexahedron facing the punching material 5 is an arc surface.

[0045] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
