[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-4 , the present invention discloses a fast bending device for hardware processing, including a processing machine 1. The top of the processing machine 1 is fixedly installed with an adjustable lower die 2, and the top of the adjustable lower die 2 is fixedly installed with an adjustable upper die 3 and a positioning device 4.

[0024] The adjustable lower die 2 includes a mounting die 201. A placing groove 203 is opened at the top of the mounting die 201. A bending groove 202 is placed inside the placing groove 203. A driving cavity 204 and a side chamber cavity 205 are opened inside the mounting die 201, and the driving cavity 204 and the side chamber cavity 205 are connected.

[0025] The inner wall of the driving cavity 204 is rotationally connected with a driving gear 206 through an inner wall power supply. A follow-up rack 207 is engaged and driven on the outside of the driving gear 206. An insertion pin 210 is fixedly installed on the outside of the follow-up rack 207 through a moving plate 209. The moving plate 209 extends into the side chamber cavity 205 through the connection between the driving cavity 204 and the side chamber cavity 205. The insertion pin 210 is located inside the side chamber cavity 205. The top of the insertion pin 210 is connected to the side end of the bending groove 202. The side chamber cavity 205 and the placing groove 203 are connected through an insertion opening 211. The insertion pin 210 is movably clamped with the insertion opening of the bending groove 202 through the insertion opening 211.

[0026] The rapid bending device for hardware processing can quickly disassemble and assemble between the bending groove 202 and the installation mold 201 by driving the driven rack 207 in the driving groove through the driving gear 206 inside the driving groove by setting the adjustable lower mold 2, so that the adjustable lower mold 2 can replace bending grooves 202 of different sizes, enabling the bending device to adapt to hardware of different shapes and sizes, avoiding the need to replace different molds when bending different hardware, significantly improving the practicality of the bending device, and thus reducing the processing cost of hardware.

[0027] The adjustable upper mold 3 includes an external frame 301. A cylinder is fixedly installed at the top end of the external frame 301, and a lifting plate 302 is fixedly installed at the movable end of the cylinder. The bottom end of the lifting plate 302 is movably connected to a bending arc block 303.

[0028] Specifically, a cross bar 208 is fixedly installed on the inner wall of the driving cavity 204, and the outer side of the driven rack 207 is slidably connected to the surface of the cross bar 208.

[0029] In this implementation, by using the driven rack 207 to slide along the surface of the cross bar 208, the movement of the driven rack 207 becomes more stable.

[0030] Specifically, a jacking cavity 212 is opened on the inner wall of the installation mold 201, and a jacking plate 213 is movably connected to the inner wall of the jacking cavity 212 through a hydraulic cylinder.

[0031] In this implementation, start the hydraulic cylinder, so that the movable end of the hydraulic cylinder drives the jacking plate 213 to lift, so that the jacking plate 213 jacks out the bending groove 202 located inside the placement groove 203, enabling the staff to replace the bending groove 202.

[0032] Specifically, the positioning device 4 includes a driving box 401. An electric push rod 402 is fixedly installed on the inner wall of the driving box 401, and a positioning plate 403 is fixedly connected to the movable end of the electric push rod 402.

[0033] In this implementation, start the electric push rod 402, so that the movable end of the electric push rod 402 drives the positioning plate 403 to displace, so that the positioning plate 403 assists in clamping the side end of the hardware, and the hardware is fixed on the installation mold 201.

[0034] When in use, first place the hardware on the installation mold 201, and place the position to be bent of the hardware above the bending groove 202. Then start the electric push rod 402, so that the movable end of the electric push rod 402 drives the positioning plate 403 to displace, so that the positioning plate 403 assists in clamping the side end of the hardware, and the hardware is fixed on the installation mold 201;

[0035] Subsequently, the adjustable upper die 3 is started, so that the movable end of the cylinder drives the bending arc block 303 to gradually descend through the lifting plate 302, and the bending arc block 303 starts to bend the hardware part below;

[0036] When it is necessary to replace the bending groove 202, the built-in power source drives the driving gear 206 to rotate, so that the driving gear 206 starts to drive the follower rack 207 to engage and transmit, so that the follower rack 207 drives the insertion pin 210 to displace through the moving plate 209. Since the moving directions of the two follower racks 207 are opposite, the movements of the two insertion pins 210 are also opposite. Therefore, the insertion pins 210 start to move away from each other inside the side chamber 205, so that the insertion pins 210 gradually move away from the bending groove 202 through the insertion ports 211, so that the fixing state between the bending groove 202 and the installation die 201 is released at this time;

[0037] Subsequently, the hydraulic cylinder is started, so that the movable end of the hydraulic cylinder drives the ejector plate 213 to lift, so that the ejector plate 213 ejects the bending groove 202 located inside the placement groove 203, so that the staff can replace the bending groove 202, and the staff also needs to replace the bending arc block 303 at the bottom end of the lifting plate 302 to adapt to the corresponding bending groove 202.

[0038] In summary, for the rapid bending device for hardware part processing, by setting the adjustable lower die 2, the driving gear 206 inside the driving groove is used to prompt the follower rack 207 to drive the insertion pin 210 through the moving plate 209 to quickly disassemble and assemble between the bending groove 202 and the installation die 201, so that the adjustable lower die 2 can replace bending grooves 202 of different sizes, so that the bending device can adapt to hardware parts of different shapes and sizes, avoiding the situation of needing to replace different dies when bending different hardware parts, significantly improving the practicability of the bending device, and thus reducing the processing cost of hardware parts.

[0039] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
