Description

Technical Field

[0001] This utility model belongs to the field of letter bending machine technology, and in particular relates to a folding 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 folding the bottom edge of the material before bending, which makes it difficult to meet the needs of the ever-developing illuminated letter industry.

Detailed Implementation

[0028] like Figure 1-9As shown: A bending mechanism for a bending machine includes two side plates 1 arranged in parallel at a certain distance. Both side plates 1 are fixedly connected to the base plate of the bending machine. A first support part 101 and a second support part 102 are provided on the upper part of the side plates 1. A material passage trough 103 is provided between the first support part 101 and the second support part 102. A bending upper die 2 is fixedly connected above the two first support parts 101. A pressing device 3 is provided between the two second support parts 102. A material passage channel for material passage is provided between the pressing device 3 and the bending upper die 2. The material passage channel is located above the material passage trough 103. A bending device 4 is provided below the pressing device 3. A driving device 5 for driving the bending device 4 is provided below the bending device 4.

[0029] The bottom surface of the upper folding mold 2 is provided with a folding surface 201, and an angle α is provided between the folding surface 201 and the bottom surface of the upper folding mold 2.

[0030] With this design, when the folding device 4 bends the material and presses it to fit the folding surface 201, the inclined folding surface 201 ensures a better bending effect for the material.

[0031] The preferred value for the included angle α is 3°±0.5°.

[0032] The clamping device 3 includes a pressure plate 301, which is slidably connected between two second support parts 102. Two cylindrical pins 302 are slidably connected between the pressure plates 301. An adjustment component is provided at one end of the two cylindrical pins 302 away from the pressure plate 301. A first spring 303 is sleeved on the cylindrical pin 302. The two ends of the first spring 303 abut against the pressure plate 301 and the adjustment component, respectively.

[0033] The first spring 303 is preferably a mold spring, which ensures that the clamping device 3 has a better clamping effect on the material.

[0034] In addition to this embodiment, the number of cylindrical pins 302 and first springs 303 may be two or more.

[0035] The adjustment assembly includes a support block 304, which is fixed between two second support parts 102. A sliding block 305 is slidably connected between the two second support parts 102. The end of the cylindrical pin 302 away from the pressure plate 301 is fixedly connected to the sliding block 305. The end of the first spring 303 away from the pressure plate 301 abuts against the sliding block 305. The sliding block 305 is located on the side of the support block 304 near the pressure plate 301. An adjusting bolt is threaded onto the support block 304. The adjusting bolt is used to adjust the sliding block 305 to be closer to or further away from the support block 304.

[0036] With this design, the position of the sliding block 305 can be adjusted by adjusting the bolt, thereby adjusting the compression of the first spring 303 and thus adjusting the clamping force.

[0037] The folding device 4 includes a roller seat plate 401, which is positioned above the driving device 5. Two roller seats 402 are positioned above the roller seat plate 401. The bottom surface of the roller seat 402 is provided with a sliding groove 4021, which is slidably connected to the roller seat plate 401. The top surface of the roller seat 402 is provided with an arc groove 4022, and a folding roller 403 is provided in both arc grooves 4022. The folding roller 403 is slidably connected to the pressure plate 301.

[0038] Two guide screws 404 are provided inside the roller seat 402. The guide screws 404 are threadedly connected to the roller seat plate 401. A second spring 405 is sleeved on the guide screw 404. The two ends of the second spring 405 abut against the roller seat plate 401 and the roller seat 402 respectively.

[0039] For guide screws, 404 stainless steel screws with equal height should be preferred.

[0040] The second spring 405 is preferably a butterfly spring, and multiple butterfly springs are fitted on each guide screw 404.

[0041] This design ensures that the folding roller 403 can stick tightly to the pressure plate 301 under the elastic force of the second spring 405; when the folding roller 403 is located below the folding upper die 2, there is enough pressure to achieve the folding operation on the bottom of the material.

[0042] A stop block 306 is fixed to the bottom surface of the pressure plate 301, and the bottom end of the stop block 306 extends to the side of the roller seat plate 401 away from the upper mold 2 of the folding edge.

[0043] With this design, when the folding device 4 moves away from the folding upper die 2, the roller seat plate 401 drives the contact block 306 away from the folding upper die 2, which in turn drives the pressure plate 301 away from the folding upper die 2, thus forming a material passage between the pressure plate 301 and the folding upper die 2, facilitating material passage; when the folding device 4 moves towards the folding upper die 2, under the elastic force of the first spring 303, the contact block 306 moves towards the folding upper die 2 together with the roller seat plate 401; when the pressure plate 301 presses the material, the contact block 306 also stops moving; the folding device 4 continues to move towards the folding upper die 2, and the folding roller 403 pushes the bottom of the material to press against the folding surface 201, realizing the folding operation of the bottom of the material.

[0044] The drive device 5 includes a support plate 501, which is fixed between two side plates 1. Two mounting plates 502 are fixed to the top surface of the support plate 501. The roller seat plate 401 is slidably connected to both mounting plates 502 through the guide rail slider assembly 503.

[0045] The guide rail slider assembly 503 includes a guide rail fixedly connected to the mounting plate 502 and a slider fixedly connected to the roller seat plate 401, with the slider and guide rail being slidably connected.

[0046] A mounting base 504 is fixedly connected inside the support plate 501. A lead screw 505 is rotatably connected inside the mounting base 504. A lead screw nut 506 is threaded onto the lead screw 505. A fixing plate 507 is fixedly connected to the lead screw nut 506. Two connecting plates 508 are fixedly connected to the side of the fixing plate 507 near the support plate 501. The connecting plates 508 are fixedly connected to the roller seat plate 401.

[0047] A motor plate 509 is provided on the side of the support plate 501 away from the fixed plate 507. The motor plate 509 is fixed between the two side plates 1. A motor 510 is fixedly installed on the motor plate 509. The output end of the motor 510 is connected to the lead screw 505 through a coupling.

[0048] During operation, the motor 510 drives the lead screw 505 to rotate, which in turn drives the folding device 4 to perform the folding operation on the bottom of the material.

[0049] 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.
