Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-4 The utility model provides an embodiment: a metal strip bending machine for processing wooden box handles, comprising a bottom plate 1 and a frame 2 installed on the top of the bottom plate 1, and a lifting drive unit 3 is installed on the top of the frame 2, and an upper right-angle mold 5 is installed on the movable end of the lifting drive unit 3, and columns 7 are installed on both sides of the top of the bottom plate 1, and a support platform 8 is installed on the top of the column 7, and a lower right-angle mold 9 is installed on the top of the support platform 8, and square-mouth telescopic columns 11 are installed at the corners of the top of the bottom plate 1, and the bottom of the bottom plate 1 is installed at the same time. A truss plate 12 is installed at the top of two square-mouth telescopic columns 11 in the Y-axis direction, and an inclined roller feeding structure 10 is installed at the top of the two truss plates 12. A plurality of equally spaced spiral springs 1201 are installed at the bottom of the truss plates 12. The bottom ends of the spiral springs 1201 are fixedly connected to the top of the support platform 8. When the upper right-angle mold 5 and the lower right-angle mold 9 are closed, the upper right-angle mold 5 forces the inclined roller feeding structure 10 and the truss plate 12 to move downward, so that the plurality of spiral springs 1201 are in a compressed state.

[0018] The lifting drive unit 3 includes a hydraulic cylinder 301 installed on the top of the frame 2, and a connecting plate 302 installed on the top of the piston rod of the hydraulic cylinder 301. Guide columns 303 are fixed at the corners of the bottom of the connecting plate 302. The bottom ends of the guide columns 303 extend to the inside of the frame 2 and are fixedly connected to the top of the upper right-angle mold 5. A steel column 6 is installed on the top of the upper right-angle mold 5, and an upper mold plate 4 is installed on the top of the steel column 6. The bottom ends of the guide columns 303 penetrate to the outside of the upper mold plate 4 and are fixedly connected to the top of the upper right-angle mold 5. When controlling the lifting of the upper right-angle mold 5, the hydraulic cylinder 301 pushes the connecting plate 302 to lift, and the connecting plate 302 drives the guide columns 303, the upper mold plate 4, the upper right-angle mold 5 and other components to move. The hydraulic cylinder 301 can provide sufficient clamping force and stability to ensure stable forming of the metal strip.

[0019] The inclined roller feeding structure 10 includes a belt transmission box 1002 fixed on the top of the truss plate 12, and a plurality of inclined roller monomers 1003 rotatably installed at equal intervals on the outer wall of one side of the belt transmission box 1002. A belt transmission structure for connecting the ends of the plurality of inclined roller monomers 1003 is arranged inside the belt transmission box 1002. A servo motor 1001 for driving one of the inclined roller monomers 1003 to rotate is installed on the outer wall of the other side of the belt transmission box 1002. The belt transmission structure includes a synchronous wheel installed at one end of the surface of each inclined roller monomer 1003, and a synchronous toothed belt for connecting a plurality of synchronous wheels.

[0020] During the process of conveying the metal strip by the inclined roller feeding structure 10, the staff starts the belt transmission box 1002 to work, and the rotational power of the belt transmission box 1002 is transmitted to each inclined roller monomer 1003 through the belt transmission structure in the belt transmission box 1002, that is, the inclined roller monomer 1003 actively conveys the metal strip, and the inclined roller monomer 1003 can reduce the friction between the metal strip and the upper and lower molds, thereby reducing the loss of the metal strip;

[0021] The inclined roller unit 1003 is made of stainless steel. The stainless steel has good wear resistance and abrasion resistance, can reduce the wear caused by friction, and extend the service life of the inclined roller unit 1003.

[0022] When the embodiment of the present application is in use, the staff first puts the metal strip to be processed into the lower right-angle die 9. At this time, the two symmetrically arranged inclined roller feeding structures 10 support the two side edges of the metal strip respectively. Then the staff turns on the lifting drive unit 3 to work, and the lifting drive unit 3 drives the upper template 4, the steel column 6 and the upper right-angle die 5 to move downward until the bottom end of the upper right-angle die 5 enters the lower right-angle die 9. During this process, the steel column 6 simultaneously forces the truss plate 12 and the inclined roller feeding structure 10 to move downward, and the square-mouth telescopic column 11 and the coil spring 1201 are in a compressed state, and the metal strip undergoes plastic deformation under the clamping of the upper right-angle die 5 and the lower right-angle die 9 to form the required bending angle and shape. When the lifting drive unit 3 pulls the upper right-angle die 5 to move upward, the coil spring 1201 gradually restores its initial shape and actively forces the truss plate 12 and the inclined roller feeding structure 10 to move upward, so that the inclined roller feeding structure 10 will be formed. The formed right-angle metal strip is lifted out of the outside of the lower right-angle die 9, and at the same time the inclined roller feeding structure 10 starts to work. The inclined roller feeding structure 10 actively rolls the metal strip, so that the unbent part of the metal strip is fed into between the upper right-angle die 5 and the lower right-angle die 9, and the bending operation continues. The device uses the inclined roller feeding structure 10 to assist in conveying the metal strip between the upper right-angle die 5 and the lower right-angle die 9, which can effectively reduce the friction of the metal strip between the upper and lower dies, making the metal strip more stable during the conveying process, reducing the contact with the upper and lower dies, and reducing the risk of loss and surface scratches of the metal strip. The elastically liftable inclined roller feeding structure 10 and the truss plate 12 can move with the opening and closing of the upper and lower right-angle die 5, 9, to ensure the stability and stability of the metal strip during the conveying process, effectively avoid the metal strip from breaking or deforming during the conveying process, and ensure the integrity of the metal strip.
