Description

Technical Field

[0001] This application relates to the field of machine tool technology, specifically to a punching machine. Background Technology

[0002] Punching machines can be classified according to their level of automation into manual punching machines, automatic positioning / alignment punching machines, fully automatic punching machines, and super fully automatic punching machines. They can also be classified according to the type of material being processed into flexible circuit board punching machines and membrane switch punching machines, commonly used for punching switches in materials such as circuit boards, printed circuit boards, film boards, and films.

[0003] Existing punching machines use rollers to support the moving material and prevent it from deviating from its direction of movement when punching. Over time, the rollers can deform due to the weight of the material, causing thinner or lighter materials to deviate from their direction of movement. This leads to punching errors and a high scrap rate.

[0004] Therefore, how to reduce the waste rate of punching machines has become a technical problem that urgently needs to be solved. Utility Model Content

[0005] In view of the above problems, this application provides a punching machine to reduce the waste rate of punching materials.

[0006] According to one aspect of the embodiments of this application, a punching machine is provided, comprising: a machine base; a receiving assembly fixed to the machine base for pulling and collecting materials; a punching assembly fixed to the machine base for punching the moving materials; and a support assembly fixed to the machine base for limiting the displacement of the moving materials; characterized in that the support assembly comprises: a support member, which is rod-shaped and includes an elastic material for supporting the materials and restoring the deformation caused by bearing the weight of the materials after the materials are removed; and a pressing member, which is rod-shaped and cooperates with the support member to clamp the materials.

[0007] Preferably, the support includes: a rod-shaped elastic core, the end of which is fixed to the machine base; and a first outer cylinder, which is sleeved around the elastic core to support the material and rotates around the elastic core under the action of the moving material.

[0008] Preferably, the elastic core is a carbon fiber core.

[0009] Preferably, the crimping component includes: a rod-shaped support core, with both ends of the support core fixed to the machine base; and a second outer cylinder, sleeved around the support core, for cooperating with the first outer cylinder to clamp the material, and rotating around the support core under the action of the moving material.

[0010] Preferably, the support core is a carbon fiber core.

[0011] Preferably, the machine base includes a first support column; the punching machine also includes a pressing block, a fixing block and a support block connected sequentially from top to bottom, with the side of the fixing block fixed to the first support column; the pressing block and the fixing block cooperate to form a first through hole for engaging the support core, with one end of the support core having an interference fit with the first through hole; the fixing block and the support block cooperate to form a second through hole for engaging the elastic core, with one end of the elastic core having an interference fit with the second through hole.

[0012] Preferably, the machine tool includes a second support column and a first locking block; the first locking block is connected to the second support column; the other end of the elastic core is locked to the first locking block.

[0013] Preferably, the first snap-fit ​​block extends to a certain length, is located close to and parallel to the elastic core, and has a certain width.

[0014] Preferably, the punching machine further includes a second locking block and a pressing strip; one end of the pressing strip is connected to the pressing block, and the other end is connected to the second locking block; the other end of the support core is locked to the second locking block.

[0015] Preferably, the punching machine includes at least two sets of cooperating support components.

[0016] This embodiment of the application uses a support member and a pressing member to clamp the material, thereby limiting the displacement of the moving material from the direction of movement. By providing the support member with an elastic material, the support member can recover the deformation caused by bearing the weight of the material after the supported material is removed, maintaining the restraining effect of the support member and the pressing member on the material. When punching lighter or thinner materials, the material can be restrained between the support member and the pressing member, making it difficult for the material to deviate from the direction of movement. This maintains the accuracy of the punching machine in punching the material and reduces the waste rate of the punching machine.

[0042] The punching machine in this application can be a manual punching machine, an automatic positioning / alignment punching machine, a fully automatic punching machine, a super fully automatic punching machine, etc. It can also be a flexible circuit board punching machine and a membrane switch punching machine, etc. The specific type of punching machine is not limited in the embodiments of this application, but it can be preferably a fully automatic punching machine.

[0043] Please see Figures 1-7 This application provides a punching machine 1, which includes: a machine base 30; a material receiving assembly 40 fixed to the machine base 30 for pulling and collecting materials; a punching assembly 50 fixed to the machine base 30 for punching the moving materials; and a support assembly 10 fixed to the machine base 30 for limiting the displacement of the moving materials; characterized in that the support assembly 10 includes: a support member 11, which is rod-shaped and includes an elastic material for supporting materials and restoring the deformation caused by bearing the weight of the materials after the materials are removed; and a pressing member 12, which is rod-shaped and cooperates with the support member 11 to clamp the materials.

[0044] Optionally, the support member 11 can be a carbon fiber rod, and the pressing member 12 can be a roller or a carbon fiber rod.

[0045] The materials can be sheet materials such as circuit boards, printed circuit boards, film boards, and thin films.

[0046] The receiving assembly 40 includes a receiving roller and a drive motor. The receiving roller rotates under the drive of the drive motor to wrap the sheet-like material around its outer surface. The punching assembly 50 is movably connected to the machine base 30 and is used to punch the moving material at multiple positions. For example, if the material moves in a first direction on the horizontal plane, the punching assembly 50 can move in the first direction on the horizontal plane and in a second direction perpendicular to the first direction to punch the material in the horizontal plane.

[0047] Among them, punching machine 1, for example Figures 1-7 The diagram shows at least two sets of cooperating support components 10.

[0048] In practical use, if the support member 11 is fixed to the machine base, the frictional resistance between the material moving with the support member 11 and the pressing member 12 is relatively large, which can easily cause significant friction on the support member 11 and the pressing member 12, resulting in surface wear of the support member 11 and the pressing member 12 and causing punching deviation. Therefore, preferably, the support member 11 includes: a rod-shaped elastic core 111, the end of which is fixed to the machine base 30; and a first outer cylinder 112, which is sleeved on the outside of the elastic core 111 to support the material and rotates around the elastic core 111 under the action of the moving material. Similarly, the pressing member 12 includes: a rod-shaped support core 121, the two ends of which are fixed to the machine base 30; and a second outer cylinder 122, which is sleeved on the outside of the support core 121 to cooperate with the first outer cylinder 112 to clamp the material and rotates around the support core 121 under the action of the moving material.

[0049] By setting the support member 11, which includes a rod-shaped elastic core 111 and a first outer cylinder 112, and the pressing member 12, which includes a rod-shaped support core 121 and a second outer cylinder 122, during the material movement, the elastic core 111 and the support core 121 are fixed to the machine base 30. The first outer cylinder 112 and the second outer cylinder 122 rotate around the elastic core 111 and the support core 121 respectively under the action of the material during movement, so that the material slides against the first outer cylinder 112 and the second outer cylinder 122 respectively, thereby reducing material separation. The friction between the first outer cylinder 112 and the second outer cylinder 122 is reduced, thereby reducing surface wear of the first outer cylinder 112 and the second outer cylinder 122 during use. Furthermore, by fixing the elastic core 111 and the support core 121 to the machine base 30, the first outer cylinder 112 and the second outer cylinder 122 rotate around the elastic core 111 and the support core 121 respectively under the action of the material during movement. This method is more stable than the method of simply setting the elastic core 111 and the support core 121 to be rotatably connected to the machine base 30.

[0050] Both the elastic core 111 and the support core 121 can be made of carbon fiber.

[0051] In the fixing structure of the elastic core 111 and the support core 121 on the machine base 30, preferably, the machine base 30 includes a first support column 31; the punching machine 1 also includes a pressing block 21, a fixing block 22 and a support block 23 connected sequentially from top to bottom, the side of the fixing block 22 is fixed to the first support column 31; the pressing block 21 and the fixing block 22 cooperate to form a first through hole 24 for snapping the support core 121, one end of the support core 121 is press-fitted with the first through hole 24; the fixing block 22 and the support block 23 cooperate to form a second through hole 25 for snapping the elastic core 111, one end of the elastic core 111 is press-fitted with the second through hole 25.

[0052] For fixing the other end of the elastic core 111 and the support core 121, preferably, the machine base 30 includes a second support column 32 and a first snap-fit ​​block 27; the first snap-fit ​​block 27 is connected to the second support column 32; the other end of the elastic core 111 is snapped into the first snap-fit ​​block 27; the punching machine also includes a second snap-fit ​​block 28 and a pressing strip 26; one end of the pressing strip 26 is connected to the pressing block 21, and the other end is connected to the second snap-fit ​​block 28; the other end of the support core 121 is snapped into the second snap-fit ​​block 28.

[0053] During the assembly of the support component 10, the elastic core 111 can be inserted into the first snap-fit ​​block 27 first, and then the elastic core 111 can be fixed in the second through hole 25. The fixing block 22 and the support block 23 can be fixed with bolts to form an interference fit between one end of the elastic core 111 and the second through hole 25. The support core 121 can be inserted into the first snap-fit ​​block 27 first, and then the support core 121 can be fixed in the first through hole 24. The pressing block 21 and the fixing block 22 can be fixed with bolts to form an interference fit between one end of the support core 121 and the first through hole 24. The whole assembly process is relatively simple and quick, and the elastic core 111 and the fixing core 121 are fixed with strong stability.

[0054] Preferably, the first snap-fit ​​block 27 extends to a certain length, is located close to and parallel to the elastic core 111, and has a certain width, so as to limit the deviation of the material by means of the first snap-fit ​​block 27 and the pressing strip 26, thereby further improving the punching accuracy of the punching machine 1 and reducing the waste rate of the punching machine 1.

[0055] Preferably, the crimping block 21 and the crimping strip 26 can be integrally formed to simplify assembly.

[0056] In this embodiment, the material is secured by the support member 11 and the pressing member 12 to limit the material from shifting in a direction other than the direction of movement. By providing the support member 11 with an elastic material, the support member 11 can recover the deformation caused by bearing the weight of the material after the material is removed, thus maintaining the limiting effect of the support member 11 and the pressing member 12 on the material. When punching lighter or thinner materials, the material can be confined between the support member 11 and the pressing member 12, making it difficult for it to shift in a direction other than the direction of movement. This maintains the accuracy of the punching machine 1 in punching the material and reduces the waste rate of the punching machine 1.
