[0026] See also Figure 1-Figure 5 , the utility model provides the following technical solutions:

[0027] like Figure 1-Figure 3 As shown, a hardware bending device comprises: an operating table 1, a mold bending mechanism 2 is detachably mounted on the upper surface of the operating table 1, and a plurality of threaded holes 101 are provided on the upper surface of the operating table 1. The threaded holes 101 are annular in design, and can be threadedly inserted into the mold bending mechanism 2 to adjust the opening spacing;

[0028] Among them, a hydraulic push rod 3 is fixedly installed on the upper surface of the operating table 1, and a mounting plate 301 is fixedly installed on one end of the piston rod of the hydraulic push rod 3.

The top clamping mechanism 4 can clamp the bent hardware between the top pressure column 302 and the top clamping mechanism 4.

[0029] Through the design of the mold bending mechanism 2, the hydraulic push rod 3, the mounting plate 301, the top pressure column 302, the top clamping mechanism 4 and the threaded hole 101, when bending the hardware, the hardware can be pressed from the top pressure column 302 and the inclined sliding surface of the top clamping mechanism 4 to the upper surface of the mounting plate 301, and the top clamping mechanism 4 pressed by the hardware will apply a top pressure to the hardware, so that the hardware can be clamped between the top pressure column 302 and the top clamping mechanism 4, and in the process of clamping the hardware, the staff only needs to press it in through external force, so that it has the effect of convenient installation, and the pressing method is safer, which reduces the risk of operators being pinched or squeezed, and improves the safety of operation. Compared with reciprocating screw rod, the staff can press in to achieve clamping more quickly, thereby improving the clamping speed and production efficiency. After the hardware is clamped, the hydraulic push rod 3 can be started to push the hardware at one end of the pressing column 302 to press against the center of the two sets of mold bending mechanisms 2, and with the continuous pressure of the hydraulic push rod 3, the hardware can be pressed and bent until it is bent to the required arc, and then the hydraulic push rod 3 can drive the bent hardware to be pulled back to its original position. Then the staff only needs to pull the top clamping mechanism 4 to the other end to free the bent hardware from clamping restrictions, so that the staff can take it out, and the process of taking out the hardware is more convenient and neat than twisting multiple turns of the screw rod.

[0030] like Figure 4-Figure 5 As shown, the mold bending mechanism 2 includes a connecting plate 201, which is detachably mounted on the upper surface of the operating table 1 through hexagonal bolts and butterfly bolts 202, and a bending top pressure wheel 203 is rotatably mounted on one end of the connecting plate 201.

[0031] The connection plate 201 can be threadedly installed into different threaded holes 101 through the butterfly bolts 202 to change the opening spacing between the two sets of bending and pressing wheels 203 .

[0032] The top clamping mechanism 4 includes a C-shaped frame 401, which is fixedly mounted on the upper surface of the mounting plate 301. One end of the C-shaped frame 401 is slidably inserted into a limiting column 406. The limiting column 406 can be completely slidably inserted into the C-shaped frame 401. One end of the limiting column 406 is fixedly mounted with a clamping plate 405. The clamping plate 405 can clamp the bent hardware between the top pressure column 302 and the clamping plate 405.

[0033] The upper surfaces of the pressing column 302 and the clamping plate 405 are both provided with inclined sliding surfaces with equal angles, which can push the clamping plate 405 during the process of pressing the hardware.

[0036] Through the design of the connecting plate 201, the butterfly bolt 202, the bending top pressure wheel 203, the pull handle 403, the spring 404 and the clamping plate 405, when bending the hardware, the hardware can be pressed from the top pressure column 302 and the inclined sliding surface of the clamping plate 405 to the upper surface of the mounting plate 301, and the clamping plate 405 pressed by the hardware will exert pressure on the spring 404 at the rear end, and the spring 404 will exert an elastic force on the clamping plate 405, and the clamping plate 405 will clamp the hardware between the top pressure column 302 and the clamping plate 405 through the elastic force, and in the process of clamping the hardware, the staff only needs to press it in through external force, so that it is convenient to load. The hydraulic push rod 3 can be started to push the hardware at one end of the pressing column 302 to press against one end of the two sets of bending pressing wheels 203 after the hardware is clamped, and the pressing column 302 can push the hardware into the center between the two sets of bending pressing wheels 203, and the hydraulic push rod 3 can be continuously pressed to bend the hardware until it is bent to the required arc, and then the hydraulic push rod 3 can drive the bent hardware to be pulled back to its original position, and then the staff only needs to pull the handle 403 to drive the clamping plate 405 to separate from the surface of the bent hardware, so that the bent hardware is not restricted by the clamping, and the staff can conveniently take it out;

[0037] Before bending the hardware, the staff can change the opening spacing between the two sets of bending top pressure wheels 203 by rotating the connecting plate 201 and threading the connecting plate 201 into the threaded holes 101 at different positions through the butterfly bolts 202, so that the opening and closing angles of the bent hardware can be adjusted, and then the bending size of the hardware can be adjusted.

[0038] According to the above technical scheme, the working steps of this scheme are summarized and sorted out: when bending the hardware, the hardware can be pressed from the inclined sliding surface of the upper surface of the top pressure column 302 and the clamping plate 405 to the upper surface of the mounting plate 301, and the clamping plate 405 pressed by the hardware will exert pressure on the spring 404 at the rear end, and the spring 404 will exert an elastic force on the clamping plate 405, and the clamping plate 405 will clamp the hardware between the top pressure column 302 and the clamping plate 405 through the elastic force, and in the process of clamping the hardware, the staff only needs to press it in through external force, and after the hardware is clamped, the hydraulic The push rod 3 pushes the hardware at one end of the pressing column 302 to press against one end of the two sets of bending pressing wheels 203, and the pressing column 302 can push the hardware to explore the center between the two sets of bending pressing wheels 203, and with the continuous pressure of the hydraulic push rod 3, the hardware can be pressed and bent until it is bent to the required arc, and then the hydraulic push rod 3 can drive the bent hardware to return to its original position. Then the staff only needs to pull the handle 403 to drive the splint 405 to detach from the surface of the bent hardware, so that the bent hardware is not restricted by clamping, and the staff can easily take it out.

[0039] In summary: the clamping method by pressing in is simpler than rotating the screw, and has obvious advantages in terms of improving production efficiency, reducing labor intensity, simplifying operation, improving stability and enhancing safety.
