Description

Technical Field

[0001] This utility model relates to the field of beveling machine technology, and in particular to a single-sided beveling machine using a rolling shear. Background Technology

[0002] Before welding, the edges of sheet metal need to be beveled according to processing requirements, necessitating the use of a beveling machine. Beveling primarily employs milling and rotary shearing. The difference lies in the cutting tools used: milling uses a milling cutter, while rotary shearing uses a rotary cutter. These two methods result in distinct bevel shapes, allowing workers to choose the appropriate machine based on their process requirements. However, existing rotary shearing beveling machines typically require manual feeding when processing small sheet metal parts, leading to low efficiency and safety issues. Utility Model Content

[0003] The purpose of this utility model is to provide a single-sided beveling machine that uses a roller shear to process the edge of a plate to form a bevel that meets the requirements of the welding process. It eliminates the need for manual feeding by workers, effectively improving processing efficiency and safety.

The rolling shear assembly 300 includes a rolling shear motor 310, a drive box 320, and rolling shears 330. The drive box 320 has an output shaft 340 rotatably mounted on one side facing the first mounting plate 210. The rolling shears 330 are fixedly mounted on the end of the output shaft 340. The outer wall of the drive box 320 below the output shaft 340 is rotatably connected to the top of the first mounting plate 210. The bottom of the first mounting plate 210 is provided with a first adjustment assembly 350, which is installed and connected to the drive box 320. The first adjustment assembly 350 is used to control the rotation of the drive box 320. The rolling shear motor 310 is fixedly mounted on the bottom of the drive box 320, and the output end of the rolling shear motor 310 is drivenly connected to the output shaft 340 to drive the output shaft 340 to rotate. The feeding assembly 400 includes a first feeding assembly 410 and a second feeding assembly 420.

[0026] The base 100 of this invention is placed on the ground or a base surface. Several casters 110 allow the base 100 to move, and the caster brakes fix the base 100 in the working position. The shock-absorbing component 120 effectively reduces the impact of vibration on the main frame 200 during production. During production, the sheet material is inserted between the first feeding component 410 and the second feeding component 420. The lifting component 430 drives the lifting platform 422 to descend, causing the first feeding wheel component 411 and the second feeding wheel component 423 to abut against the bottom and top surfaces of the sheet material, respectively. This clamps and fixes the sheet material on the feeding component 400, and the end of the sheet material engages with the rolling shear 330. Then, the first adjustment component 350 is controlled to adjust the angle of the drive box 320, thereby adjusting the relative position of the roller shear 330 and the board, so that the board can form a bevel that meets the requirements. Then, the roller shear motor 310 is turned on, and the roller shear motor 310 drives the output shaft 340 to rotate the roller shear 330. The roller shear 330 will process the edge of the board, and at the same time, the roller shear 330 will push the board to move along the feeding component 400.
