[0002] In order to remove burrs on parts caused by machining, to facilitate assembly of parts, and to prevent the ends of parts from cutting people, it is generally necessary to chamfer the ends of parts. Steel sheets are usually chamfered with ordinary small bench drills, and the chamfering depth is controlled by the strength of the operator's hand-held swing joystick, which will lead to poor consistency after chamfering. When chamfering large steel sheets, it is difficult for operators to lift the steel sheets by themselves; at the same time, during the chamfering process of steel sheets, debris often remains on the workbench, which will lead to quality risks such as workpiece padding and hole deepening. All of these will affect the efficiency and quality of steel sheet chamfering.

[0003] Therefore, designing a device that has good chamfering consistency, controllable chamfering depth, low requirements on personnel skills, and can automatically chamfer steel sheets is a problem that needs to be solved urgently at this stage. Summary of the invention

[0004] The purpose of the present invention is to provide a steel sheet processing chamfering device, aiming to solve the technical problem in the prior art that the chamfering depth of the steel sheet is controlled by the force of a hand-held swinging joystick, which leads to poor consistency after chamfering.

Placing the steel sheet in the feed trough 11 and pushing the steel sheet to move can save the operator's effort, and there is no need to lift the steel sheet and align it with the bench drill for chamfering. The steel sheet can be grinded in sequence by passing through multiple grinding components 21 in sequence, avoiding the uneven grinding end caused by grinding the steel sheet at one time.

[0026] Specifically, refer to Figure 1 to Figure 4 As shown, the grinding mechanism 20 includes a plurality of bevel grinding assemblies 30, a straight edge grinding assembly 40 disposed at the rear end of the bevel grinding assembly 30, and a driving mechanism for driving the bevel grinding assembly 30 and the straight edge grinding assembly 40 to rotate. In this embodiment, the bevel grinding assembly 30 performs preliminary grinding on the end of the steel plate to make the end of the steel plate triangular, and then the straight edge grinding assembly 40 grinds the end of the steel plate after the bevel grinding assembly 30 grinds the sharp corner of the triangle flat to complete the chamfering. The steel sheet is grinded in turn by the bevel grinding assembly 30 and the straight edge grinding assembly 40 to avoid a one-time grinding of the steel sheet resulting in an uneven grinding end.

[0027] More specifically, refer to Figure 1 to Figure 4 As shown, two bevel grinding assemblies 30 are provided to grind the ends of the steel plate at 30 degrees and 45 degrees at one time.

The steel plate passes between the two grinding disc wheels 32, and the two grinding disc wheels 32 grind the upper and lower surfaces of the end of the steel plate, and then passes through the grinding roller, the tip of the steel plate is smoothed by the grinding roller, and the chamfer is completed. The steel sheet can be polished in sequence by passing through multiple grinding assemblies 21 in sequence, so as to avoid the steel sheet being polished once and causing the polished end to be not smooth.

[0029] More specifically, refer to Figure 1 to Figure 4 As shown, the included angles between the grinding disc wheel 32 and the material chute 11 are 30 degrees and 45 degrees respectively.

[0030] Specifically, refer to Figure 1 to Figure 4 As shown, the bevel grinding assembly 30 also includes a threaded sleeve 33 sleeved on the bevel drive shaft 31 and threadedly connected to the bevel drive shaft 31, and the grinding disc wheel 32 is arranged at one end of the threaded sleeve 33 close to the feed trough 11. A fixed sleeve 34 is also extended from the end of the threaded sleeve 33 away from the feed trough 11, and a plurality of fixed screw holes 35 are arranged on the fixed sleeve 34.
