Description

Technical Field

[0001] This utility model relates to the field of roller pressing machinery and equipment, and in particular to a roller pressing and cutting device for preventing the adhesion of scrap materials. Background Technology

[0002] Many automotive parts, such as car bumpers, glass tracks, and radiator crossbeams, are manufactured using roll forming technology. The roll-formed blanks need to be cut to length according to design requirements. In the existing roll forming cutting process, the blank is cut by the downward movement of a moving blade. During the cutting process, magnetic debris is generated. This debris adheres to the moving blade, causing abnormal wear and blade ejection, reducing the blade's lifespan. Blade ejection can also lead to product scrap.

[0003] Therefore, the industry urgently needs a roller blank cutting device that can prevent scrap material from adhering to the moving blade during the roller cutting process. Utility Model Content

[0004] The purpose of this invention is to provide a roller-pressed blank cutting device that can prevent scrap material from adhering to the moving blade, so as to ensure that abnormal wear of the moving blade and the occurrence of top blade accidents are not caused.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A roller-pressing cutting device for preventing material adhesion includes a stationary blade, a stationary blade mounting block, a guide column, a moving blade mounting seat, a hydraulic cylinder mounting seat, a hydraulic cylinder, a high-pressure air pipeline, a moving blade, and a base frame. Two identical stationary blades are provided, mirror-image arranged, with a gap between them to accommodate the vertical movement of the moving blade. Both stationary blades are fixedly mounted on the base frame via the stationary blade mounting block. Each stationary blade has a contoured material cavity and an air blowing hole. The guide column is mounted on the base frame, and the moving blade mounting seat moves vertically along the guide column. The hydraulic cylinder mounting seat is located at the upper end of the base frame, and the hydraulic cylinder is fixedly mounted on the hydraulic cylinder mounting seat. The moving blade is mounted on the moving blade mounting seat, which is driven vertically by the hydraulic cylinder.

[0007] The aforementioned roller cutting device for preventing material adhesion has an oil spray pipe located above the stationary blade, facing the cutting edges of both the stationary and moving blades.

[0008] The aforementioned roller cutting device for preventing material adhesion has an air blowing hole on one of the two stationary blades, and the air blowing hole is located in the center of the stationary blade.

[0009] In the aforementioned roller cutting device for preventing material adhesion, the air blowing hole is inclined with its lower end facing downwards from the stationary blade. A thread is provided at the upper end of the air blowing hole, and the air blowing hole is connected to a high-pressure air pipeline through the thread.

[0010] This utility model has the following advantages:

[0011] This invention features an air blowing hole on the stationary blade. During operation, high-pressure gas is delivered to the air blowing hole via a high-pressure gas pipeline. The high-pressure gas continuously blows away magnetic debris generated during the cutting process. Simultaneously, an oil spray pipe is installed on the cutting blade holder, and the oil sprayed from the pipe smoothly discharges the cut debris. This invention, through high-pressure gas blowing and oil spraying, prevents debris generated during the cutting process from adhering to the moving blade, thereby improving abnormal wear of the moving blade, eliminating blade tipping, increasing the service life of the moving blade, and reducing the occurrence of product scrap.

Detailed Implementation

[0016] This utility model discloses a roller-pressing and cutting device for preventing the adhesion of scrap materials, such as... Figure 1 , Figure 2 As shown, two stationary blades 1 are mirror-image arranged and mounted on the base frame 10 via stationary blade mounting blocks 2. A contouring cavity 1-2 is located in the center of each stationary blade 1. The rolled blank produced in the previous process passes through the contouring cavity 1-2 for cutting. The contour shape of the contouring cavity 1-2 matches the cross-sectional shape of the blank to prevent deformation during the cutting process. The moving blade 9 is mounted on a moving blade mounting seat 5, which is driven by a hydraulic cylinder 7 to reciprocate up and down along the guide column 3 for cutting operations.
