Description

Technical Field

[0001] The utility model relates to the technical field of copper wire processing equipment, in particular to a high-efficiency wire cutting device for copper braided wires. Background Art

[0002] Copper wire is a common component in circuit breakers. In order to improve the anti-interference ability of the equipment, the copper wire is woven into braided wire. During the processing of the copper braided wire, it is not only necessary to weave the copper wires, but also to weld the two braided copper wires together, and then cut the welding position so that there are solder joints at both ends of the copper braided wire for subsequent use. The cutting device in the prior art has the following problems: First, after the copper braided wire is welded, a large amount of heat will be retained on the copper braided wire due to its good thermal conductivity, which will cause the solder joint position of the copper braided wire to soften, which may lead to poor cutting effect during cutting; second, during the cutting process, the solder joint position may be deformed due to the large downward pressure distance of the cutting head, thereby affecting subsequent use; third, during the cutting process, the copper braided wire may slide relative to each other, resulting in insufficient cutting accuracy. Summary of the invention

[0003] In order to solve the above problems, the utility model provides an efficient wire cutting device for copper braided wire, which can improve cutting accuracy, ensure that the copper braided wire is fully cooled, and avoid welding point deformation of the copper braided wire during cutting.

[0004] The technical solution of the utility model: an efficient wire cutting device for copper braided wire, comprising an equipment base, a feeding device connected to the equipment base, a wire pulling device connected to the equipment base, a cutting device connected to the equipment base and a controller, the feeding device comprising a feeding track connected to the equipment base, a limiting groove being provided on the feeding track, the limiting groove being adapted to the width of the copper braided wire to be processed, the wire pulling device comprising a first sliding base slidably connected to the equipment base, an electric clamping claw connected to the first sliding base and a first hydraulic cylinder for driving the first sliding base to move in a horizontal direction, the movement direction of the first sliding base being consistent with the direction in which the copper braided wire slides on the limiting groove The cutting device includes a second sliding base slidably connected to the equipment base, a third sliding base slidably connected to the equipment base, an upper cutting head fixedly connected to the second sliding base, a lower cutting head fixedly connected to the third sliding base, a first linear servo motor for driving the second sliding base to move in a vertical direction, and a second linear servo motor for driving the third sliding base to move in a vertical direction, the upper cutting head and the lower cutting head respectively correspond to the end positions of the feeding track, the upper cutting head is located directly above the lower cutting head, and the controller is respectively electrically connected to the first linear servo motor, the second linear servo motor, the first hydraulic cylinder and the electric clamping claw.

[0005] Using the above technical solution, first, the copper braided wire to be processed is placed on the limiting groove, and one end of the copper braided wire is exposed from the end of the limiting groove. Then, the controller controls the first hydraulic cylinder to drive the first sliding base to move in the direction of the feed track until the electric clamping claw corresponds to the position of the copper braided wire to be cut. Then, the controller controls the electric clamping claw to clamp the copper braided wire. Then, the controller controls the first hydraulic cylinder to drive the first sliding base to move in the opposite direction, so that the copper braided wire is pulled out. The next welding point on the copper braided wire is located directly above the upper cutting head. Below, the controller line controls the second linear servo motor to drive the third sliding base to move vertically upward, so that the lower cutting head contacts the copper braided wire, and then the controller controls the first linear servo motor to drive the second sliding base to move vertically downward, and the copper braided wire is cut by the upper cutting head and the lower cutting head. Compared with the traditional cutting device, the advantage of this is that the movement of the cutting head can be accurately controlled by controlling the movement of the upper cutting head and the lower cutting head by two servo motors, thereby avoiding deformation of the solder joint position of the copper braided wire during the cutting process.

[0006] The utility model is further configured as follows: it also includes a wire pressing device, which includes a fourth sliding base slidably connected to the equipment base, a wire pressing plate fixedly connected to the fourth sliding base, and a second hydraulic cylinder for driving the fourth sliding base to move in a vertical direction, the wire pressing plate is located directly above the limiting groove, the cross-sectional shape and size of the wire pressing plate are adapted to the limiting groove, and the controller is electrically connected to the second hydraulic cylinder.

[0007] By adopting the above technical solution, before cutting, the second hydraulic cylinder is controlled by the controller to drive the fourth sliding base to move vertically downward, so that the wire pressing plate presses the copper braided wire located on the limiting groove, thereby avoiding relative sliding of the copper braided wire during the cutting process, thereby improving the cutting accuracy.

[0008] The utility model is further configured as follows: it also includes a cooling device, a liquid circulation groove is provided inside the feed track, the cooling device includes a first connecting pipe connected to the liquid circulation groove, a second connecting pipe connected to the other end of the liquid circulation groove and a circulating water pump connected to the first connecting pipe and the second connecting pipe, and the circulating water pump is electrically connected to the controller.

[0009] By adopting the above technical solution, the circulating water pump is controlled by the controller to start working, and water flows from the first connecting pipe into the liquid flow groove and flows back to the circulating water pump from the second connecting pipe, thereby providing accelerated heat dissipation for the copper braided wire located on the limiting groove, ensuring that the copper braided wire can be cooled quickly, thereby further improving the cutting effect.

[0010] The utility model is further configured as follows: a photoelectric sensor fixedly connected to the device base is also provided on the device base, the photoelectric signal position emitted by the photoelectric sensor corresponds to the contact point position of the upper cutting head and the lower cutting head, and the controller is electrically connected to the photoelectric sensor. With the above technical solution, since the photoelectric signal position emitted by the photoelectric sensor corresponds to the contact point position of the upper cutting head and the lower cutting head, when the electric clamping claw pulls the soldering point position on the copper braided wire to the bottom of the upper cutting head, the photoelectric sensor sends an electrical signal to the controller, and the controller controls the first linear servo motor and the second linear servo motor to start working, and the upper cutting head and the lower cutting head complete the cutting work, which can further improve the cutting accuracy.
