Description

Technical Field

[0001] This utility model belongs to the field of letter bending machine technology, and in particular relates to a punching mechanism for a letter bending machine. Background Technology

[0002] A letter bending machine is an automated advertising device controlled by software and processed by a program to automatically bend the outline of illuminated metal letters. Currently, in advertising production, the surface processing of illuminated metal letters is mainly completed by engraving machines, plasma cutting machines, or laser cutting machines. With the rapid development of the advertising production industry, advertising equipment for surface processing has entered a mature development stage. The emergence of letter bending machines is bound to bring a revolutionary breakthrough to the advertising production industry. Through software control, letter bending machines can accurately fold the edges of metal letters and achieve high-precision fitting with the letter surface and base plate, greatly increasing the strength and aesthetics of illuminated letters. However, existing letter bending machines do not have the function of punching holes in the material before bending, which makes it difficult to meet the needs of the ever-developing illuminated letter industry.

Detailed Implementation

[0025] like Figure 1-6 As shown: A punching mechanism for a bending machine includes a base plate 1, on which two vertical plates 2 are fixedly connected. The two vertical plates 2 are arranged parallel to each other at a certain distance. A mounting plate 3 is fixedly connected to the side of each vertical plate 2 near the material. A first punching device 4 and a second punching device 5 are arranged between the two mounting plates 3. The first punching device 4 and the second punching device 5 are arranged symmetrically. A pushing device 6 for driving the first punching device 4 and the second punching device 5 is arranged between the two vertical plates 2. A driving device 8 for driving the first punching device 4 is arranged below the pushing device 6. A guide assembly 7 is also provided on the two vertical plates 2.

[0026] The first punching device 4 includes a first punch mounting plate 401, a guide groove is provided between the two mounting plates 3, the first punch mounting plate 401 is slidably connected to the guide groove, a first die mounting plate 402 is fixedly connected to the side of the first punch mounting plate 401 away from the pushing device 6, and a first material passage 403 is provided between the first punch mounting plate 401 and the first die mounting plate 402.

[0027] The second punching device 5 includes a second punch mounting plate 501, which is slidably connected to a guide groove. A second die mounting plate 502 is fixedly connected to the side of the second punch mounting plate 501 away from the pushing device 6. A second material passage 503 is provided between the second punch mounting plate 501 and the second die mounting plate 502. The second material passage 503 is correspondingly provided with the first material passage 403.

[0028] This design facilitates the passage of materials between the first material passage 403 and the second material passage 503. By adjusting the vertical position of the first punch mounting plate 401 and the second punch mounting plate 501 in the guide groove, materials of different widths can pass through the first punching device 4 and the second punching device 5.

[0029] Both mounting plates 3 have elongated holes 301. Two fixing screws 408 are installed in both the first punch mounting plate 401 and the second punch mounting plate 501. The fixing screws 408 pass through the corresponding elongated holes 301 and are locked with nuts, which makes it easy to fix the first punch mounting plate 401 and the second punch mounting plate 501 to the mounting plate 3. This also makes it easy to fix the first punching device 4 and the second punching device 5 to the mounting plate 3 after the position is adjusted.

[0030] A support sleeve 404 is fixedly connected inside the first punch mounting plate 401 and the second punch mounting plate 501. A punch 407 is fixedly connected inside the first die mounting plate 402 and the second die mounting plate 502. A punch assembly is slidably connected inside each of the two support sleeves 404. One end of the punch assembly is connected to the pushing device 6, and the other end of the punch assembly is slidably connected to its corresponding die 407.

[0031] This design allows the punch assembly to be used in conjunction with the die 407, facilitating punching operations on materials.

[0032] Material guides 409 are fixedly connected to both the first die mounting plate 402 and the second die mounting plate 502.

[0033] This design prevents waste material from scattering everywhere. The waste material falls down along the feeder 409 onto the base plate 1, making it easy for staff to collect and clean.

[0034] The pushing device 6 includes a push plate 601, which has two first roller holes 6011. The first roller holes 6011 are oblong holes and are horizontally arranged. Two first support columns are fixed between the two vertical plates 2. A first roller 602 is rotatably connected to each of the two first support columns. The first roller 602 is slidably connected to its corresponding first roller hole 6011.

[0035] Push blocks 603 are provided on both sides of the push plate 601. Two second support columns are fixed between the two push blocks 603. A second roller 604 is rotatably connected to each of the two second support columns. Two second roller holes 6012 are opened in the push plate 601. The second roller holes 6012 are oblong holes and are inclined. The second roller 604 is slidably connected to its corresponding second roller hole 6012.

[0036] With this design, the vertical movement of the pusher block 603 can push the pusher plate 601 to move horizontally, thereby driving the punch assembly to move horizontally to perform punching operations on the material.

[0037] The punch assembly includes a punch 405, which is slidably connected to its corresponding support sleeve 404. The punching end of the punch 405 is slidably connected to its corresponding die 407. A punch pad 406 is fixedly connected to the other end of the punch 405. A mounting groove 6013 is provided at one end of the push plate 601 near the punch assembly. The punch pad 406 is slidably connected to the mounting groove 6013.

[0038] This design facilitates the horizontal movement of the punch 405 driven by the push plate 601, and also facilitates the movement of the punch 405 together with the first punching device 4 and the second punching device 5 when adjusting their vertical positions.

[0039] The angle between the inclined surface of the second roller hole 6012 and the vertical surface of the push plate 601 is 9°±1°.

[0040] The guide assembly 7 includes two connecting plates 701, which are fixedly connected to their corresponding upright plates 2. A third support column is fixedly connected between the two connecting plates 701. Two third rollers 702 are rotatably connected to the third support column. The third rollers 702 are slidably connected to their corresponding push blocks 603. A spacer 703 is provided between the two third rollers 702 and is fitted onto the third support column.

[0041] With this design, when the push block 603 moves up and down, the third roller 702 and the upright plate 2 work together to limit and guide it.

[0042] The drive device 8 includes a mounting base 802, which is fixedly connected to the base plate 1. A lead screw 801 is rotatably connected inside the mounting base 802. The bottom ends of the two push blocks 603 are fixedly connected to the mounting block 803. A lead screw nut 804 is fixedly connected inside the mounting block 803. The lead screw nut 804 is threadedly connected to the lead screw 801.

[0043] A motor 806 is fixedly installed below the base plate 1 via a motor bracket 805, and the output end of the motor 806 is connected to the lead screw 801 for transmission.

[0044] During operation, the motor 806 drives the lead screw 801 to rotate, which in turn drives the push block 603 to move up and down through the mounting block 803. The second roller 604 moves up and down with the push block 603, which in turn pushes the push plate 601 to move horizontally, which in turn drives the punch 405 to move horizontally. The punch 405 works in conjunction with the die 407 to punch the material.

[0045] For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of this utility model, based on the teachings of this utility model, still fall within the protection scope of this utility model.
