[0025] The inside of the material box 7 is slidably connected with a pressing plate 19, the surface of the moving clamp 4 is fixedly connected with two extrusion blocks 6, the surfaces of the two extrusion blocks 6 are slidably connected with the inside of the material box 7, one end of the extrusion block 6 inside the material box 7 is flag-shaped, the surface of the extrusion block 6 is slidably connected with the surface of the pressing plate 19, that is, the inclined surface of the extrusion block 6 is provided with a groove, and the surface of the pressing plate 19 is provided with a protrusion matched with the groove, so as to connect the extrusion block 6 and the pressing plate 19 together.

[0026] The surface of the workbench 1 is fixedly connected with two limiting plates 8, the structures of the two limiting plates 8 are the same, the surface of the limiting plate 8 is fixedly connected with an L-shaped frame 13, the upper end of the L-shaped frame 13 is fixedly connected with the bottom of the material box 7, the surface of the limiting plate 8 is slidably connected with a side plate 12, the upper end of the side plate 12 is fixedly connected with the bottom of the moving plate 18, the surface of the side plate 12 close to the L-shaped frame 13 is embedded with a ball 11, the inner wall of the L-shaped frame 13 is also embedded with a ball 11, and the inner walls of the material box 7 are also embedded with balls 11, and then through the arrangement of the balls 11, the friction between the copper bars and the inside of the material box 7 and between the side plate 12 and the L-shaped frame 13 is reduced, so that the copper bars can smoothly slide in the material box 7 and between the side plate 12 and the L-shaped frame 13, and the smooth operation of the device is ensured.

[0027] Further, the surface of the limiting plate 8 is provided with a blanking groove 20, which provides a blanking channel for the copper bar. The surface of the limiting plate 8 is provided with a sliding groove 21, which is in communication with the blanking groove 20. The surface of the moving clamp 4 is fixedly connected with a fixed plate 10. The surface of the fixed plate 10 is slidably connected with a moving rod 9. The surface of the moving rod 9 is in sliding communication with the inner wall of the blanking groove 20. The surface of the moving rod 9 is provided with a moving groove 25. The depth of the moving groove 25 near the fixed plate 10 is deeper than the depth of the moving groove 25 away from the fixed plate 10. The surface of the moving rod 9 is provided with a movable groove 26 in the shape of a right trapezoid. The movable groove 26 is in communication with the moving groove 25. The depth of the inclined groove of the movable groove 26 gradually increases until it is the same as the depth of the deep groove of the moving groove 25. The depth of the other two side grooves of the movable groove 26 is the same as the depth of the shallow groove of the moving groove 25. The inner wall of the sliding groove 21 is fixedly connected with a fixed sleeve 23. The inside of the fixed sleeve 23 is slidably connected with a sliding rod 22. The surface of the sliding rod 22 and the surface of the fixed sleeve 23 are in sliding communication with the inner wall of the moving groove 25 and the inner wall of the movable groove 26. One end of the sliding rod 22 inside the fixed sleeve 23 is fixedly connected with a spring 24. The end of the spring 24 away from the sliding rod 22 is fixedly connected with the inside of the fixed sleeve 23, so as to reset the sliding rod 22. When the sliding rod 22 and the fixed sleeve 23 are in the moving groove 25, the moving rod 9 blocks the blanking groove 20, so that the copper bar cannot continue to fall along the blanking groove 20.

[0028] The surface of the moving rod 9 is also fixedly connected with a spring 24. The end of the spring 24 away from the moving rod 9 is fixedly connected with the inside of the fixed plate 10, so as to reset the moving rod 9.

[0029] Principle: in the process of feeding and discharging, the staff first pull the pull rod 16, and then drive the threaded rod 17 in the material box 7 sliding, make the compression spring 15 compression again, then put the copper bar between the clamp plate 27 and the inner wall of the material box 7, then no longer pull the pull rod 16, and then under the elastic force of the compression spring 15, the clamp plate 27 will be extruded and fixed between the clamp plate 27 and the inner wall of the material box 7, then make the moving clamp 4 move, make the moving clamp 4 gradually away from the fixed clamp 5, and then drive the extrusion block 6 in the material box 7 sliding, so that the inclined surface of the extrusion block 6 extrudes the pressing plate 19, so that the pressing plate 19 slides down in the material box 7, and then the pressing plate 19 extrudes the copper bar close to the inner wall of the material box 7, so that the copper bar slides down in the material box 7, and gradually slides out of the material box 7 through the gap between the moving plate 18 and the inner wall of the material box 7. In this process, the movement of the moving clamp 4 drives the moving rod 9 to slide in the sliding groove 21. Because the moving clamp 4 and the fixed clamp 5 are close to each other before, the fixed sleeve 23 and the sliding rod 22 are located in the deep groove of the moving groove 25 at this time, so that the fixed sleeve 23 and the sliding rod 22 move to the step between the deep groove and the shallow groove of the moving groove 25 with the movement of the moving rod 9. Because the step blocks the movement of the sliding rod 22, the sliding rod 22 and the fixed sleeve 23 slide along the inclined groove of the movable groove 26 at this time. Because the sliding rod 22 and the fixed sleeve 23 are in a fixed state and cannot move, the moving rod 9 is driven to move horizontally in the sliding groove 21, so that the moving rod 9 moves to the outside of the limiting plate 8 and stretches the spring 24 in the fixed plate 10, so that the moving rod 9 gradually no longer blocks the discharging groove 20. While the sliding rod 22 and the fixed sleeve 23 slide in the inclined groove of the movable groove 26, the inner wall of the inclined groove of the movable groove 26 extrudes the sliding rod 22, so that the sliding rod 22 gradually shrinks into the fixed sleeve 23 and compresses the spring 24. Then, with the sliding of the sliding rod 22 and the fixed sleeve 23 in the movable groove 26, the sliding rod 22 and the fixed sleeve 23 move to the horizontal groove of the movable groove 26. At this time, the moving rod 9 no longer blocks the discharging groove 20, so that the copper bar between the moving clamp 4 and the fixed clamp 5 after processing can continue to slide in the discharging groove 20 and fall into the collecting box 3 through the discharging port 14. Then the sliding rod 22 and the fixed sleeve 23 move to the vertical groove and the horizontal groove of the movable groove 26. At this time, under the elastic force of the spring 24 in the fixed plate 10, the moving rod 9 returns to its original state, and the sliding rod 22 and the fixed sleeve 23 enter the shallow groove of the moving groove 25. At the same time, the restoration of the moving rod 9 makes the moving rod 9 block the discharging groove 20 again. Then, with the moving clamp 4 away from the fixed clamp 5, the pressing plate 19 extrudes the copper bar from the material box 7, and then enters the discharging groove 20 along the side plate 12 and the L-shaped frame 13. Then make the moving clamp 4 close to the fixed clamp 5 to bend the copper bar, so that the extrusion block 6 and the pressing plate 19 gradually return to their original state.Meanwhile, the slide rod 22 and the fixed sleeve 23 directly move from the shallow groove to the deep groove along the track of the moving groove 25, and then the slide rod 22 restores to the original state under the elastic force of the spring 24, and simultaneously, the copper bars are bent along with the gradually closing of the moving clamp 4 and the fixed clamp 5, and thus the automatic feeding and discharging of the copper bars can be realized during the opening of the mold, so that the workers are not required to place and take out the copper bars in sequence, thereby improving the bending efficiency of the device for the copper bars and improving the use effect of the device, which is worth promoting.

[0030] Although the embodiments of the present application have been shown and described, it should be understood by those ordinary skilled in the art that various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
