[0045] Further, the top of the mounting column 202 is fixedly connected with a first hydraulic cylinder 203a, the piston shaft of the first hydraulic cylinder 203a passes through the top of the mounting column 202 and is fixedly connected to the top of the moving block 203, the bottom of the moving block 203 is fixedly connected with a return spring 203b, the bottom end of the return spring 203b is fixedly connected to the inner bottom of the mounting column 202, the first hydraulic cylinder 203a is used to apply an external force to the moving block 203, so that the moving block 203 drives the lifting arm 204 to move vertically, and the return spring 203b is set to facilitate the resetting of the moving block 203;

[0046] A rotating shaft 206a passes through the top center position of the sleeve rod 206 in a vertically rotating manner, and a first knob 206b is fixedly connected to the top of the rotating shaft 206a. A bevel gear 206c is sleeved on the bottom end of the rotating shaft 206a and the center position of the outer wall of the first screw rod 207. The bevel gears 206c are meshingly connected. The first knob 206b and the rotating shaft 206a are configured to drive the bevel gear 206c to rotate, and the meshing connection between the bevel gears 206c is used to drive the first screw rod 207 to rotate.

[0047] The operation process of this embodiment is as follows: first, the bending block 205 is replaced according to the bending demand, and the connecting block 205a at the top of the bending block 205 is respectively passed through the front and rear ends of the surface of the lifting arm 204, and the first knob 206b is rotated. The first knob 206b drives the bevel gear 206c to rotate synchronously through the rotating shaft 206a. Under the action of the meshing connection between the bevel gears 206c, the first screw rod 207 is rotated synchronously, and then under the action of the threaded connection between the first screw rod 207 and the inner rod 207b, the inner rod 207b moves to the outside of the sleeve rod 206, and when one end of the inner rod 207b is clearance-fitted in the inside of the clamping groove 205b, the first knob 206b is stopped from being rotated, and the fixing of the bending block 205 is completed;

[0048] Next, the spacing between the support blocks 209 is adjusted by rotating the second knob 208b, which drives the second screw rod 208a to rotate synchronously.

When the spacing between the support blocks 209 reaches a preset distance, the second knob 208b is stopped from being rotated, and the spacing between the support blocks 209 is adjusted.

[0049] Finally, the metal parts to be bent are placed on the support block 209, and the first hydraulic cylinder 203a is started, so that the piston shaft of the first hydraulic cylinder 203a drives the moving block 203 to move vertically, and then the lifting arm 204 drives the bending block 205 to apply external force to the metal parts, thereby realizing the bending of the metal parts. Specific embodiment 2

[0051] See also Figure 1 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 As shown, based on the first embodiment, auxiliary components 3 for assisting the loading and bending of metal parts are provided on both sides of the top of the workbench 1. At the same time, the auxiliary components 3 can also be set to limit the metal parts being bent.

[0052] Specifically, the mounting blocks 301 in the auxiliary component 3 are respectively movably connected to the inner sides of the grooves 101 located on both sides of the top of the workbench 1 in the transverse direction, and a heat conducting plate 302 is fixedly connected to the outer wall of one side of the mounting block 301. The heat conducting plate 302 is made of heat conducting material. A plurality of groups of mounting holes 302a are provided on the outer wall of the heat conducting plate 302 away from the mounting block 301 at equal intervals in the longitudinal direction. The insides of the mounting holes 302a are all fitted with electric radiation tubes 303 in clearance. One end of the electric radiation tube 303 is fixedly connected to a fixing plate 303a. The heat is quickly transferred to the metal parts through the setting of the heat conducting plate 302, and the electric radiation tube 303 is installed through the setting of the mounting holes 302a. The electric radiation tube 303 emits heat after being energized, thereby heating the metal parts. The fixing plate 303a is used to connect the plurality of groups of electric radiation tubes 303 to each other, thereby facilitating their rapid loading and unloading.

[0053] The second hydraulic cylinder 304a is fixedly connected to both sides of the bottom of the mounting block 301, and the piston shaft of the second hydraulic cylinder 304a passes through the bottom of the mounting block 301 and is fixedly connected to a lifting plate 304b. The lifting plate 304b is movably connected to both sides of the inside of the mounting block 301, and the front and rear ends of the upper surface of the lifting plate 304b are welded with mounting plates 304c. The front and rear ends of the upper surface of the mounting plate 304c are fixedly connected with multiple groups of fixing seats 304d at equal intervals in the horizontal direction. A guide wheel 304 is rotatably connected between the front and rear adjacent fixing seats 304d. The top of the guide wheel 304 passes through the through slot 301b located at the top of the mounting block 301. The second hydraulic cylinder 304a and the lifting plate 304b are arranged to drive the mounting plate 304c, and the guide wheel 304 is installed by the arrangement of the mounting plate 304c and the fixing seat 304d. The arrangement of the guide wheel 304 can reduce the friction coefficient between the metal parts and the mounting block 301, thereby facilitating the loading and unloading of the metal parts to be bent or after bending.

[0054] A plurality of groups of L-shaped seats 301a are fixedly connected to the front and rear end surfaces of the mounting block 301 at equal intervals in the horizontal direction. The front and rear ends of the top of the mounting block 301 are movably connected to a limit plate 305. A threaded rod 305a is rotatably connected to the center position of the back surface of the limit plate 305. One end of the threaded rod 305a away from the limit plate 305 is threadedly penetrated through the L-shaped seat 301a in the middle and is fixedly connected to a third knob 305b. The limit plate 305 is used to limit the metal parts to prevent them from shifting during the bending process. At the same time, the threaded rod 305a and the third knob 305b are used to adjust the position of the limit plate 305, thereby facilitating the limiting of metal parts of different sizes.

[0055] Furthermore, mounting feet 302b are welded at the front and rear ends of the outer wall of one side of the mounting block 301, and the lateral arms of the mounting feet 302b are respectively fixedly connected to the front and rear ends of the lower surface of the heat conducting plate 302. The mounting feet 302b are triangular in shape, and the mounting feet 302b are made of heat insulating material to prevent the heat on the heat conducting plate 302 from being transferred to the mounting block 301. The heat conducting plate 302 is installed by setting the mounting feet 302b.

[0056] Limiting rods 305c are welded on both sides of the back surface of the limiting plate 305, and the ends of the limiting rods 305c away from the limiting plate 305 respectively penetrate the L-shaped seats 301a on both sides and are threadedly sleeved with nuts 305d. The setting of the limiting rods 305c and the nuts 305d realizes the movability of the limiting plate 305 on the mounting block 301 and limits the movement distance of the limiting plate 305.

[0057] The operation process of this embodiment is as follows: first, the metal parts to be bent are placed on the heat conducting plate 302, and the power of the electric radiation tube 303 is turned on, so that the electric radiation tube 303 emits heat after being powered on, and the heat is transferred to the metal parts through the heat conducting plate 302, thereby heating the metal parts.

[0058] Then, the second hydraulic cylinder 304a is started, and the piston shaft of the second hydraulic cylinder 304a drives the lifting plate 304b and the guide wheel 304 to move up and down, so that the top end of the guide wheel 304 passes through the through slot 301b and contacts the bottom of the metal component, and applies an external force to the heated metal component, so that the metal component moves to the bottom of the bending structure;

[0059] Finally, the third knob 305b is turned, and the third knob 305b drives the threaded rod 305a to rotate synchronously, and under the action of the threaded connection between the threaded rod 305a and the L-shaped seat 301a, the limit plate 305 moves. When the limit plate 305 respectively contacts the front and rear ends of the metal component, the third knob 305b is stopped, and the metal component is bent through the bending structure.
