Description

Technical Field

[0001] This application relates to the field of sign processing technology, and in particular to a corner cutting device for sign processing. Background Technology

[0002] Signage is used to create directional signs with text, images, and other content to indicate direction and provide warnings. To ensure the aesthetics and safety of the signs, the four sharp corners are usually rounded off during processing. This requires a corner-cutting device. Existing corner-cutting devices typically consist of a hydraulic cylinder, a connecting plate, four cutters, a bracket, and a base plate. In use, the hydraulic cylinder's hydraulic rod drives the four cutters downwards through the connecting plate to cut the four sharp corners of the sign. However, the four cutters are usually fixedly mounted on the connecting plate, making them unsuitable for signs of different sizes, thus limiting their applicability. Utility Model Content

[0003] To address the limitation that the four cutters of existing corner-cutting devices are mostly fixedly mounted on the connecting plate and cannot be applied to signs of different sizes, this application provides a corner-cutting device for sign processing.

[0004] The corner-cutting device for sign processing provided in this application adopts the following technical solution:

[0005] A corner-cutting device for sign processing includes a base plate, a bracket, and four screws. The bracket is fixedly installed at the edge of the top of the base plate by a mounting component. A hydraulic cylinder is fixedly installed at the top of the bracket, and the telescopic rod of the hydraulic cylinder moves through the bracket. A movable plate is welded to the end of the telescopic rod of the hydraulic cylinder. A guide for limiting the movable plate is provided on one side of the bracket. The two ends of the four screws are respectively welded to eight inner sidewalls of the movable plate. Movable blocks are movably fitted on the outer surfaces of the four screws, and one side of each of the four movable blocks is in contact with the other four inner sidewalls of the movable plate. An arc-shaped cutter is welded to the bottom of each of the four movable blocks. A nut A and a nut B are threaded onto the outer surfaces of each of the four screws. The top of the base plate has four rows of holes, each of which corresponds to one of the four arc-shaped cutters.

[0006] Preferably, the mounting component consists of a mounting block and four bolts A. The inner bottom wall of the mounting block contacts the top surface of the substrate, and the side wall of the mounting block contacts the back side of the bracket. All four bolts A are threaded through the mounting block, with two bolts A being threaded to the substrate and the other two bolts A being threaded to the bracket.

[0007] Preferably, the guide member consists of a guide rod and a sliding hole. The guide rod is welded to one side of the movable plate, and the sliding hole is opened on the other side of the bracket. One end of the guide rod movably passes through the sliding hole, and two sides of the guide rod are respectively attached to two inner sidewalls of the sliding hole.

[0008] Preferably, mounting feet are welded to the four corners of the bottom of the substrate, and bolts B are threaded through the top surfaces of the four mounting feet.

[0009] Preferably, a scale is attached to the top surface of the movable plate, and each of the four scales is engraved with a scale value.

[0010] Preferably, a fixing block is welded to both ends of the top of the substrate, and a bolt C is threaded through one side of each fixing block.

[0011] In summary, this application includes the following beneficial technical effects: After moving the positions of the four movable blocks according to the size of the sign, the four arc-shaped cutters at the bottom of the four movable blocks are positioned one-to-one with the four corners of the sign. At this time, rotating the four nuts A and four nuts B respectively abuts against the two sides of the four movable blocks, fixing the four movable blocks. Then, the hydraulic rod of the hydraulic cylinder drives the four movable blocks and the four arc-shaped cutters to move down through the movable plate. After the four arc-shaped cutters extend into the four holes, the purpose of cutting the corners of the sign can be achieved. Compared with the prior art, it has the effect of cutting corners on signs of different sizes. Attached Figure Description

Detailed Implementation

[0016] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be described in further detail.

[0017] Example 1:

[0018] Corner cutting device for sign processing, refer to Figure 1-3 Mounting feet 61 are welded to the four corners of the bottom of the substrate 1. Bolts B62 are threaded through the top surfaces of the four mounting feet 61. By rotating the four bolts B62 to connect with the threaded surface of the external worktable, the substrate 1 can be mounted on the external worktable. The bracket 2 is fixedly mounted on the edge of the top of the substrate 1 by a mounting component 3. The mounting component 3 consists of a mounting block 31 and four bolts A32. The inner bottom wall of the mounting block 31 contacts the top surface of the substrate 1, and the side wall of the mounting block 31 contacts the back side of the bracket 2. All four bolts A32 are threaded through the mounting block. 31, where two bolts A32 are threaded to the base plate 1 and the other two bolts A32 are threaded to the bracket 2, so as to achieve the purpose of fixing the bracket 2 and the base plate 1. Fixing blocks 81 are welded to both ends of the top of the base plate 1. Bolts C82 are threaded through one side of the two fixing blocks 81. There are four rows of holes at the top of the base plate 1. The nameplate is placed on the base plate 1, and the four corners of the nameplate are respectively above the four rows of holes. Then, the four bolts C82 are rotated so that one end of two bolts C82 abuts against the two sides of the nameplate, so that the nameplate can be positioned.

[0019] Reference Figure 1-3 A hydraulic cylinder 41 is fixedly installed at the top of the bracket 2. The hydraulic cylinder 41 is preferably... The telescopic rod of hydraulic cylinder 41 extends through bracket 2. A movable plate 42 is welded to the end of the telescopic rod of hydraulic cylinder 41. The bottom of the hydraulic rod of hydraulic cylinder 41 is located in the cavity of hydraulic cylinder 41, dividing the cavity of hydraulic cylinder 41 into an upper cavity and a lower cavity. Hydraulic cylinder 41 is controlled by an external hydraulic system. Two external oil pipes in the external hydraulic system are connected to an external directional valve. One external oil pipe is connected to the lower cavity of hydraulic cylinder 41, and the other external oil pipe is connected to the upper cavity of hydraulic cylinder 41. The external directional valve is connected to an external hydraulic pump through an external oil supply pipe. The external hydraulic pump is placed in an external oil tank. Another external oil discharge pipe connected to the external directional valve is inserted into the external oil tank. The pump is started via an external switch. After one of the external hydraulic pumps is started using the external switch, the external hydraulic pump draws oil from the external oil tank and enters the external directional valve through the external oil supply pipe. At this time, operating the external directional valve causes oil to enter the lower chamber of the hydraulic cylinder 41 through one of the external oil pipes. The oil in the upper chamber of the hydraulic cylinder 41 is transported to the external directional valve through another external oil pipe, and then discharged to another external hydraulic pump through the external directional valve and another oil supply pipe, and finally flows into the external oil tank. At this time, the oil in the lower chamber of the hydraulic cylinder 41 will push against the hydraulic rod of the hydraulic cylinder 41 to extend, and the hydraulic rod of the hydraulic cylinder 41 will drive the movable plate 42 to move downward. A guide 5 is provided on one side of the bracket 2 to limit the movement of the movable plate 42. Composed of a guide rod 51 and a sliding hole 52, the guide rod 51 is welded to one side of the movable plate 42, and the sliding hole 52 is opened on the other side of the bracket 2. One end of the guide rod 51 movably passes through the sliding hole 52, and two sides of the guide rod 51 are respectively attached to two inner sidewalls of the sliding hole 52. When the guide rod 51 moves downward with the movable plate 42, the guide rod 51 can only move vertically downward inside the sliding hole 52. At this time, the guide rod 51 can restrict the movable plate 42, so that the movable plate 42 will not rotate. The two ends of the four screws 43 are respectively welded to eight inner sidewalls of the movable plate 42. Movable blocks 44 are movably fitted on the outer surface of the four screws 43, and one side of each of the four movable blocks 44 is attached to the other four inner sidewalls of the movable plate 42. 43 supports and guides four movable blocks 44. Each of the four movable blocks 44 has an arc-shaped cutter 45 welded to its bottom end. A scale 7 is adhered to the top surface of the movable plate 42, with graduations printed on each scale 7. Referring to these graduations, the distance the movable block 44 has moved can be determined, ensuring that the four arc-shaped cutters 45 correspond one-to-one with the four corners of the sign. Simultaneously, the four rows of holes correspond one-to-one with the four arc-shaped cutters 45. Each of the four screws 43 has a nut A46 and a nut B47 threaded onto its outer surface. After moving the four movable blocks 44, rotating the four nuts A46 and B47 to engage with the sides of the four movable blocks 44 will fix them in place.Then, the hydraulic rod of the hydraulic cylinder 41 drives the four movable blocks 44 and four arc-shaped cutters 45 to move downwards via the movable plate 42. After the four arc-shaped cutters 45 extend into the four rows of holes, the four corners of the sign can be cut.
