[0033] Furthermore, the hydraulic clamping assembly 22 includes a cylinder 221, which is fixedly connected to the top of the machine tool body 1, and the output end of the cylinder 221 is fixedly connected to the first telescopic rod 222, and the end of the first telescopic rod 222 away from the cylinder 221 is fixedly connected to the second slider 223, and the top of the machine tool body 1 is fixedly connected to a clamping box 227, and a fourth slide groove 226 is provided inside the clamping box 227, and a clamping block 225 is slidably connected inside the fourth slide groove 226, and a third slide groove 224 is provided on the side of the clamping block 225 close to the second slider 223, and the clamping block 225 is slidably connected to the third slide groove 224 to prevent the copper busbar from being unstable during the bending process.

[0036] Furthermore, there are two groups of clamping blocks 225 symmetrically distributed inside the clamping box 227 to stably clamp copper busbars of different thicknesses.

[0037] Example 2:

[0038] See also Figure 5, and in combination with Embodiment 1, it is further obtained that the bending mechanism 3 includes a second servo motor 31. The second servo motor 31 is fixedly connected to the bottom of the machine tool main body 1. The output end of the second servo motor 31 is fixedly connected with a gear disc 32.

[0039] In the actual operation process, when this device is in use, first place the copper bar between the four groups of rollers 2112. At this time, turn on the first servo motor 211 to make the threaded rod 212 rotate. When the threaded rod 212 rotates, the two sliding plates 213 on the threaded rod 212 and the first sliding rod 214 move relatively towards the copper bar along the inside of the first chute 215 opened inside the machine tool body 1. When the two sliding plates 213 clamp the copper bar, at this time, turn on the motor 218 to make the transmission shaft 219 on its output end rotate. When the transmission shaft 219 rotates, the first pulley 2110 fixedly connected to the top also rotates accordingly. At the same time, due to the transmission connection of the belt 2111 between the first pulley 2110 and the second pulley 2113, the second pulley 2113 also rotates. At this time, because the copper bar is squeezed and clamped by the four groups of rollers 2112, the other two groups of rollers 2112 also start to rotate. At the same time, under the rotation of the four groups of rollers 2112, the copper bar is driven to move forward. When the copper bar moves to one end of the machine tool body 1, control the cylinder 221 to make the first telescopic rod 222 pull the second slider 223 to slide forward along the third chute 224 on the clamping block 225. At this time, the two clamping blocks 225 slide relatively outward respectively on the fourth chute 226 opened inside the clamping box 227. When the copper bar moves between the two clamping blocks 225, control the cylinder 221 to make the first telescopic rod 222 pull the second slider 223 to slide backward along the third chute 224 opened on the clamping block 225. At the same time, drive the two clamping blocks 225 to move relatively inward along the fourth chute 226 opened inside the clamping box 227 to clamp and fix the copper bar. When the copper bar is stabilized, at this time, turn on the second servo motor 31, and the gear disk 32 at its output end rotates accordingly. When the gear disk 32 rotates, the two toothed plates 34 engaged with it slide relatively on the second sliding rod 33. At the same time, the extrusion groove 35 fixed above it also moves accordingly. When it moves to one side of the copper bar, control the second telescopic rod 37 through the two hydraulic cylinders 36 to make the two extrusion heads 38 move towards the two extrusion grooves 35 respectively. When the two extrusion heads 38 extrude the copper bar until it reaches the inside of the two extrusion grooves 35, the extrusion and bending of the copper bar are completed.
