[0024] Please refer to Figures 1-4 The present application is a sheet metal bending side edge positioning bracket, which comprises:

[0025] The positioning structure comprises a first supporting plate 11, a second supporting plate 12 and a positioning column 14. The upper end of the first supporting plate 11 is movably connected to one side of the lower end of the second supporting plate 12. Symmetrical second positioning holes 16 are formed at equal distances on one side of the end of the first supporting plate 11. Symmetrical first positioning holes 13 are formed at equal distances on one side of the end of the second supporting plate 12. The lower end of the positioning column 14 extends into the first positioning hole 13 and the second positioning hole 16. An arc surface positioning groove 15 is formed on one side of the central position of the outer surface of the positioning column 14.

[0026] The first supporting plate 11 and the second supporting plate 12 are used in cooperation with the first positioning hole 13 and the second positioning hole 16 to install the positioning column 14. The positioning column 14 is used to limit the long strip-shaped sheet metal to be processed, so that the operator can have 2 points longitudinally and 1 point laterally, and the long strip-shaped sheet metal to be processed can be leveled, thereby ensuring the processing accuracy. In addition, the first supporting plate 11 and the second supporting plate 12 can be used interchangeably, thereby improving the applicability.

[0027] The mounting structure comprises a mounting port 23. The mounting port 23 is formed on both sides of the central position of one end of the first supporting plate 11 and the second supporting plate 12. The mounting port 23 on the first supporting plate 11 is embedded with a first leveling plate 21, and the mounting port 23 on the second supporting plate 12 is embedded with a second leveling plate 22.

[0028] The mounting structure further comprises a locking bolt 24 extending out of the mounting hole 23 and into the sheet metal bending equipment frame.

[0029] The mounting hole 23 cooperates with the locking bolt 24 to mount and fix the bracket, and the first leveling plate 21 and the second leveling plate 22 ensure the leveling treatment of the mounting hole 23 in the non-use state.

[0030] The mounting structure further comprises a locking bolt 24 extending out of the mounting hole 23 and into the sheet metal bending equipment frame.

[0031] The locking bolt 24 cooperates with the locking bolt 24 to mount and fix the bracket, and the first leveling plate 21 and the second leveling plate 22 ensure the leveling treatment of the mounting hole 23 in the non-use state.

[0032] The working principle is as follows: when the second bracket 12 is used to assist in sheet metal processing of the long strip-shaped sheet metal, force is applied to the first bracket 11, the appropriate angle is adjusted by rotating the thread, the first leveling plate 21 in the mounting hole 23 of the first bracket 11 is taken out, the locking bolt 24 is placed in the mounting hole 23, and the tightening force is applied to complete the structure fixation. At this time, the long strip-shaped sheet metal to be processed is limited by the positioning column 14 cooperating with the arc positioning groove 15, so that the operator has 2 points in the longitudinal direction and 1 point in the horizontal direction, and the long strip-shaped sheet metal to be processed can be placed flat. If the second bracket 12 is damaged, the first bracket 11 can be used.

[0033] The scheme ensures the stability of the operator's position during the bending process, improves the dimensional accuracy of the short side bending of the long strip-shaped sheet metal part, and the first bracket 11 and the second bracket 12 can be converted and applied to each other, improving the structural applicability and functionality.

[0034] Please refer to Figures 1-4 The embodiment further comprises a quick dismounting structure, the quick dismounting structure comprises an annular groove 41, a longitudinal groove 42 and a dismounting block 43, the annular groove 41 is arranged in the central position of the inner wall of the first positioning hole 13 and the second positioning hole 16, the longitudinal groove 42 is symmetrically arranged on the opposite sides of the inner wall of the first positioning hole 13 and the second positioning hole 16 and communicates with the annular groove 41, and the dismounting block 43 is symmetrically fixed on the opposite sides of the lower part of the outer surface of the positioning column 14 and extends into the longitudinal groove 42.

[0035] The abutment between the inner wall of the annular groove 41 and the dismounting block 43 can ensure the stability of the structure of the positioning column 14, and the longitudinal groove 42 can satisfy the extension of the dismounting block 43 into the annular groove 41.

[0036] The dismounting block 43 is smaller than the length of the inner wall of the longitudinal groove 42, and the outer surface of the dismounting block 43 is in contact with the inner wall of the annular groove 41.

[0037] Working principle: when installing the positioning column 14, the dismounting block 43 is extended into the annular groove 41 through the longitudinal groove 42, then a rotating force is applied to the dismounting block 43, so that the dismounting block 43 is rotated to other positions of the inner wall of the annular groove 41, and the fixing of the structure of the positioning column 14 is completed by the contact between the two, and the reverse operation can be performed to disassemble.

[0038] The scheme is convenient and fast to dismount, convenient to use, and improves the assembly efficiency
