[0002] Copper wire is an important component in the circuit breaker. The processing steps of copper wire include bending, cutting, flattening, etc. In the prior art, in order to meet the needs of mass production, these processes are usually completed automatically by mechanical equipment, especially the two processing steps of bending and cutting are completed by the same equipment, so that the specifications of each processed copper wire can be guaranteed to meet the requirements, and at the same time, the subsequent feeding work can be reduced. However, the processing equipment in the prior art has the following problems: first, multiple ejectors are required to be used to bend the copper wire during the processing process, the process is complicated, and the equipment needs to perform many actions, so the efficiency is relatively low; second, the copper wire is During the processing, it is easy for one end of the copper wire to be bent while the other end is raised, which will cause the bending angle of the copper wire to deviate. The processed copper wire does not fully meet the processing requirements, especially for some special copper wires used for circuit breakers. This copper wire includes a first end, a connecting part and a second end, wherein the first end is perpendicular to the second end and the connecting part, respectively, and the second end and the central axis of the connecting part are in the same horizontal plane, but the second end and the central axis of the connecting part form a certain angle. For copper wires with special requirements, there is no corresponding processing equipment in the prior art, so a new type of bending and cutting machine is needed. Summary of the invention

[0003] In order to solve the above problems, the utility model provides an integrated bending and cutting device for copper wire, which improves the bending accuracy of copper wire, improves the processing efficiency, and ensures the bending quality of copper wire. The technical solution of the utility model: an integrated bending and cutting device for copper wire, comprising an equipment base, a processing platform connected to the equipment base, a copper wire feeding track arranged on the processing platform, a bending device connected to the equipment base, a cutting device connected to the equipment base, and a controller, the bending device comprising a first bending block fixedly connected to the processing platform, a second bending block slidably connected to the processing platform, a sliding base slidably connected to the equipment base, a third bending block fixedly connected to the sliding base, a first hydraulic cylinder for driving the second bending block to move, and a linear servo motor for driving the sliding base to move, one side of the first bending block corresponds to the end position of the copper wire feeding track, and the movement direction of the second bending block is horizontal and toward Towards the position of the first bending block, the movement direction of the sliding base is the vertical direction, the position of the third bending block corresponds to the position of the copper wire feeding track close to one end of the first bending block, the first bending block is provided with a first inclined plane, and the second bending block is provided with a second inclined plane, the bevel angles of the first inclined plane and the second inclined plane are respectively adapted to the angle at which the copper wire needs to be bent in the horizontal direction, when the first bending block and the second bending block are in contact, the first inclined plane and the second inclined plane overlap, the cutting device includes a cutting head fixedly connected to the sliding base, the distance from the end of the cutting head to the bottom of the sliding base is smaller than the distance from the end of the third bending block to the bottom of the sliding base, and the controller is electrically connected to the linear servo motor and the first hydraulic cylinder respectively.

[0004] By adopting the above technical scheme, first, the copper wire to be processed is fed through the copper wire feeding track. When the end of the copper wire moves to the copper wire feeding track and the distance extending from the first bending block matches the required distance of the front end of the copper wire, the linear servo motor is controlled by the controller to drive the sliding base to move vertically downward. Since the position of the third bending block corresponds to the position of the copper wire feeding track close to one end of the first bending block, the third bending block will bend the copper wire 90 degrees in the vertical direction. Then, the first hydraulic cylinder is controlled by the controller to drive the second bending block to move in the horizontal direction, so that the copper wire is bent in the horizontal direction. The bending angle of the copper wire is consistent with the first inclined plane and the second inclined plane. The bevel angle is adapted to the size, so that the bending work of the copper wire is completed. Compared with the traditional bending method, in addition, after the bending action is completed, since the cutting head is connected to the sliding base, the sliding base continues to slide down a certain distance, and the cutting head will cut the bent copper wire segment. The distance between the cutting head and the third bending block depends on the length of the copper wire to be processed. First of all, the device uses a linear servo motor to improve the accuracy of the third bending block pressing down, and avoid the third bending block pressing down too fast to squeeze and deform the copper wire. In addition, compared with traditional equipment, the device requires fewer actions when bending, which can improve processing efficiency.

[0005] The utility model is further configured as follows: it also includes a material pressing device, which includes a first slider slidably connected to the processing platform, a first material pressing plate fixedly connected to the first slider, and a second hydraulic cylinder for driving the first slider to move in a vertical direction. When the first slider slides a certain distance, the bottom of the first material pressing plate can contact the upper surface of the copper wire feeding track, and the first material pressing plate is close to the feed port position of the copper wire feeding track, and the controller is electrically connected to the second hydraulic cylinder.

[0006] By adopting the above technical solution, when the feed length of the copper wire meets the processing requirements, the controller controls the second hydraulic cylinder to drive the first slider to move vertically downward, so that the first pressing plate presses the copper wire to prevent the rear end of the copper wire from warping up during the subsequent bending and cutting process, thereby improving the bending accuracy and cutting accuracy.

At this time, the position where the second pressing plate presses is the position of the copper wire close to one end of the first bending block. Therefore, the position stability of the copper wire during the bending process can be further improved, thereby further improving the processing accuracy.

[0010] By adopting the above technical scheme, when the upper floating block is in the initial state, the lowest point on the upper floating block maintains contact with the highest point on the lower floating block. When the third bending block moves vertically downward to bend the copper wire in the vertical direction, the controller controls the fourth hydraulic cylinder to drive the lower floating block to move in the horizontal direction, so that the lowest point on the lower floating block contacts the lowest point on the upper floating block. At this time, the upper floating block slides down to avoid deformation at the bending part of the copper wire, thereby improving the bending quality of the copper wire.

In position, the movement direction of the sliding base 9 is vertical, the position of the third bending block 10 corresponds to the position of one end of the copper wire feeding track 3 close to the first bending block 7, the first bending block 7 is provided with a first inclined surface 13, and the second bending block 8 is provided with a second inclined surface 14, the bevel angles of the first inclined surface 13 and the second inclined surface 14 are respectively adapted to the angle at which the copper wire needs to be bent in the horizontal direction, when the first bending block 7 and the second bending block 8 are in contact, the first inclined surface 13 and the second inclined surface 14 coincide, the cutting device 5 includes a cutting head 15 fixedly connected to the sliding base 9, the distance from the end of the cutting head 15 to the bottom of the sliding base 9 is smaller than the distance from the end of the third bending block 10 to the bottom of the sliding base 9, and the controller 6 is electrically connected to the linear servo motor 12 and the first hydraulic cylinder 11, respectively.

[0016] First, the copper wire to be processed is fed through the copper wire feeding track 3. When the end of the copper wire moves to the copper wire feeding track 3 and the distance extending from the first bending block 7 matches the required distance of the front end of the copper wire, the linear servo motor 12 is controlled by the controller 6 to drive the sliding base 9 to move vertically downward. Since the position of the third bending block 10 corresponds to the position of one end of the copper wire feeding track 3 close to the first bending block 7, the third bending block 10 will bend the copper wire 90 degrees in the vertical direction. Then, the first hydraulic cylinder 11 is controlled by the controller 6 to drive the second bending block 8 to move in the horizontal direction, so that the copper wire is bent in the horizontal direction. The bending angle of the copper wire is consistent with the inclination of the first inclined surface 13 and the second inclined surface 14. The angle sizes are adapted to each other, thus completing the bending of the copper wire, compared with the traditional bending method. In addition, after completing the bending action, since the cutting head 15 is connected to the sliding base 9, the sliding base 9 continues to slide down a certain distance, and the cutting head 15 will cut the bent copper wire segment. The distance between the cutting head 15 and the third bending block 10 depends on the length of the copper wire to be processed. First of all, the device uses a linear servo motor 12, which can improve the accuracy of the third bending block 10 pressing down, and avoid the third bending block 10 pressing down too fast to squeeze and deform the copper wire. In addition, compared with traditional equipment, the device requires fewer actions when bending, which can improve processing efficiency. It also includes a pressing device 16, which includes a first slider 17 slidably connected to the processing platform 2, a first pressing plate 18 fixedly connected to the first slider 17, and a second hydraulic cylinder 19 for driving the first slider 17 to move in a vertical direction. When the first slider 17 slides a certain distance, the bottom of the first pressing plate 18 can contact the upper surface of the copper wire feeding track 3, and the first pressing plate 18 is close to the feeding port of the copper wire feeding track 3. The controller 6 is electrically connected to the second hydraulic cylinder 19.

[0017] When the copper wire feed length meets the processing requirements, the controller 6 controls the second hydraulic cylinder 19 to drive the first slide block 17 to move vertically downward, so that the first pressing plate 18 presses the copper wire to prevent the rear end of the copper wire from warping during the subsequent bending and cutting process, thereby improving the bending accuracy and cutting accuracy.

[0019] When the feeding length of the copper wire meets the processing requirements and the first pressing plate 18 presses one end of the copper wire, the controller 6 controls the third hydraulic cylinder 22 to drive the second slider 20 to move vertically downward, so that the second pressing plate 21 presses the copper wire. At this time, the position where the second pressing plate 21 presses is the position of the copper wire close to one end of the first bending block 7. Therefore, the position stability of the copper wire during the bending process can be further improved, thereby further improving the processing accuracy.

[0020] The processing platform 2 is provided with an upper floating block 23 slidably connected to the processing platform 2 and a return spring 24 connected between the upper floating block 23 and the processing platform 2, the first bending block 7 is fixedly connected to the upper floating block 23, the equipment base 1 is provided with a lower floating block 25 slidably connected to the equipment base 1 and a fourth hydraulic cylinder 26 for driving the lower floating block 25 to move in a horizontal direction, the upper floating block 23 is provided with a third inclined surface 27, the lower floating block 25 is provided with a fourth inclined surface 28, when the lower floating block 25 slides a certain distance, the third inclined surface 27 and the fourth inclined surface 28 coincide, and the controller 6 is electrically connected to the fourth hydraulic cylinder 26.

[0021] When the upper floating block 23 is in the initial state, the lowest point on the upper floating block 23 keeps in contact with the highest point on the lower floating block 25. When the third bending block 10 moves vertically downward to bend the copper wire in the vertical direction, the fourth hydraulic cylinder 26 is controlled by the controller 6 to drive the lower floating block 25 to move in the horizontal direction, so that the lowest point on the lower floating block 25 contacts the lowest point on the upper floating block 23. At this time, the upper floating block 23 slides down, which can avoid deformation at the bending part of the copper wire, thereby improving the bending quality of the copper wire. After the bending work is completed, the controller 6 controls the fourth hydraulic cylinder 26 to drive the lower floating block 25 to reset, and the upper floating block 23 will automatically reset under the influence of the pulling force of the reset spring 24.
