In the use process of the equipment, a material belt on a discharging frame firstly enters a feeding mechanism 2, the material belt is fed into a first feeding guide rail 3 through the feeding mechanism 2 and then enters a second feeding guide rail 4, the material belt is cut according to a preset length by a cutting mechanism 5 in the process of entering the second feeding guide rail 4 from the first feeding guide rail 3, and the length of the cut material belt is controlled by the feeding mechanism 2. When the material belt is sent out from the tail part of the second feeding guide rail 4, the 2 groups of liftable positioning fixtures 12 are in a lifting state, a third feeding guide rail is formed by gaps between the front and rear 2 liftable positioning fixtures 12, when the material belt passes through the third feeding guide rail and passes through the upper part of the forming guide rail 6, the head end of the material belt is finally sent out of the third feeding guide rail for a certain distance, then the shaping cylinder 14 pushes the head end bending forming die 13 to move forwards, at the moment, the liftable positioning fixtures 12 still keep a lifting state, the material belt in the third feeding guide rail formed by the liftable positioning fixtures 12 is fixed by the liftable positioning fixtures, and after the material belt extending out of the head end of the third feeding guide rail is contacted with the head end bending forming die 13, the material belt is bent under the pressure effect of the material belt. The bending angle is controlled by the extending distance of the head end bending forming die 13, and after the head end bending forming die 13 extends to a preset distance, the shaping cylinder 14 retreats. When the material belt to be processed passes through the forming guide rail 6, the inner die 7 and the positioning ejector rod 8 are respectively positioned at the front side and the rear side of the material belt, and a gap is reserved between the inner die 7 and the positioning ejector rod 8, so that the material belt can pass through the gap. After the head end of the material belt is bent, the 4 liftable positioning fixtures 12 descend, at the moment, the forming stepping motor 9 works to drive the inner mold push rod 15 in front of the material belt to push out, the inner mold push rod 15 moves forwards along the forming guide rail 6 and pushes the forming mold structure, namely, the inner mold 7 and the positioning push rod 8 move backwards along the forming guide rail 6 together and pass through between the 2 movable rollers 36, and the material belt can be bent under the action of the acting force of the inner mold 7 and the extrusion force of the movable rollers 36. In the process of the forming die structure driving the material belt to move backwards along the forming guide rail 6, the movable roller 36 moves inwards by a certain distance under the action of the double-head driving cylinder, the material belt is further extruded, and the extruded material belt final forming structure is shown in fig. 10. After the molding is completed, the movable roller 36 is moved outward to open by the double-head driving cylinder thereof. Because the material belt is made of metal and has certain elasticity, the material belt can rebound outwards to form a structure shown in figure 11. Meanwhile, the material pressing cylinder 10 acts to drive the forming die structure to move forwards along the forming guide rail 6, the formed material belt can be pushed out under the action of the positioning ejector rod 8, and then the formed material belt is taken away. And then repeating the next processing.

Because the material belt may have burrs at the head end in the cutting process of the cutting mechanism, the head end of the cut material belt stretches out to the outside 2mm after entering the second feeding guide rail 4, and the distance of the stretching out of the material belt cannot reach the set value due to the existence of the burrs, so that the subsequent bending position is affected. Therefore, after the material belt enters the second feeding guide rail 4, the open metal sheet clamping head 18 clamps the left side and the right side of the material belt from the chute 19 under the action of the metal sheet clamping cylinder 17, and then the left cylinder 16 is positioned again to drive the material belt to move rightwards under the action of the left cylinder 16, so that the extending distance of the head end of the material belt is ensured to reach a set value. The method is repeated, and the accurate positioning of the material belt is ensured, so that the consistency of the bimetal structure obtained by subsequent processing is ensured.
The machine frame 11 is further provided with a material taking left cylinder and a material taking right cylinder 20, the head ends of the material taking left cylinder and the material taking right cylinder 20 are connected with a material taking up and down cylinder 21, the head ends of the material taking up and down cylinder 21 are connected with a material taking clamping cylinder 22, two head ends of the material taking clamping cylinder 22 are respectively provided with 1 material taking clamping head 23, and the material taking clamping heads 23 are located right above the junction of the extension line of the second feeding guide rail 4 and the forming guide rail 6. After the bimetallic strip forming structure, the upper and lower feeding cylinders 21 drive the feeding clamping cylinder 22 and the feeding clamping head 23 to move downwards, the feeding clamping head 23 clamps the formed bimetallic strip under the action of the feeding clamping cylinder 22, then the upper and lower feeding cylinders 21 move upwards, the left and right feeding cylinders 20 drive the bimetallic strip to move rightwards to the position above a material box arranged on the outer side of the machine body 1, and then the feeding clamping head 23 is opened to finish one-time feeding work. And the automatic material taking can be realized by repeating the steps.
The feeding mechanism 2 comprises 2 rollers 24 which are symmetrically arranged front and back, and the rollers 24 are connected with a feeding motor. The material belt passes through the 2 rollers 24 in the feeding process, and the material belt is conveyed rightward under the friction force of the rollers 24 in the process of driving the rollers 24 to rotate by the feeding motor. Under the mutual clamping action of the rollers 24, when the rollers 24 rotate the material belt, the rollers 24 stop the material belt immediately, so that the accurate feeding work of the material belt can be realized, and when the material belt is sent out from the discharging frame, the material belt is of a wavy structure, and the surface of the material belt can be leveled under the pressure action of the rollers 24.
The machine body 1 in front of the feeding mechanism 2 is also provided with a shaping mechanism, and the shaping mechanism is composed of 2 rows of shaping roller groups 25 which are arranged in a staggered way.

During the cutting process, the cutting cylinder 26 drives the front blade 27 to move forwards to be engaged with the rear blade 29, so that the material belt passing through between the 2 blades can be cut off. Because the cutting process can have 1 pressure to the material belt, the pressure can make the material belt head end of cutting off the department buckle, and the material belt head end of head end buckling just can't aim at the import of second pay-off guide rail 4 like this, so be equipped with the sheetmetal on back cutting edge 29 and pierce through hole 30, can guarantee that the material belt cuts off the in-process, and its head end can not take place to buckle.
A shaping angle adjusting screw 31 is also arranged between the head end bending forming die 13 and the shaping cylinder 14. The adjusting screw 31 for shaping angle can enable the head end of the head end bending forming die 13 to deflect, so that when the head end bending forming die 13 moves forwards, the position of the contact point between the head end bending forming die 13 and the material belt extending out of the liftable positioning clamp 12 is changed, and under the condition that the forward travel of the shaping cylinder 14 is unchanged, the position of the contact point between the head end bending forming die 13 and the material belt is changed, so that the forming angle of the head end of the material belt is changed.
