Description

Technical Field

[0001] The utility model relates to the technical field of wire drawing machines, and specifically, to a large copper wire drawing machine. Background Art

[0002] A traction wire drawing machine is a mechanical device used for stretching and processing metal wire rods. It is mainly used for pulling and drawing large-diameter metal billets such as copper wires and aluminum rods through traction, gradually reducing the diameter, and making wire rods that meet the specifications required for subsequent processes. The traction wire drawing machine is a core device in the production processes of industries such as cables, metal products, and other industries that require wire rod pretreatment.

[0003] Due to the characteristics of diameter reduction by drawing of the traction wire drawing machine, it has high efficiency when processing wire rods with a relatively small total length such as aluminum rods. However, when processing coiled copper wires with a relatively large total length, due to the limited traction stroke, the phenomenon that the tension cannot be evenly distributed will occur, ultimately leading to the problem that the diameter of the finished wire rod is uneven. Summary of the Utility Model

[0004] The utility model provides a large copper wire drawing machine, which solves the problem of uneven diameter of the finished wire rod in the related art.

[0005] The technical solution of the utility model is as follows:

[0006] A large copper wire drawing machine includes:

[0007] A limit frame;

[0008] A slider, which is slidably arranged on the limit frame;

[0009] An adjusting roller, which is arranged on the slider;

[0010] A fixed roller, which is rotatably arranged on the limit frame, and the axis direction of the fixed roller is parallel to the axis direction of the adjusting roller;

[0011] A screw rod, which is rotatably arranged on the limit frame along the horizontal direction and is in threaded cooperation with the slider, and is used to drive the adjusting roller to slide;

[0012] A guide wheel, which is rotatably arranged on the adjusting roller.

[0013] As a further technical solution, it further includes a diameter measuring instrument, which is arranged on the limit frame and is located at one end close to the fixed roller.

[0014] As a further technical solution, it further includes a servo motor, which is arranged on the limit frame. The power output shaft of the servo motor is connected to the screw rod, and the diameter measuring instrument is electrically connected to the servo motor.

[0015] As a further technical solution, the guide wheel is slidably arranged on the adjusting roller.

[0016] As a further technical solution, it further includes a locking member, and the locking member is symmetrically sleeved on the adjusting roller with respect to the guide wheel for fixing the position of the guide wheel.

[0017] As a further technical solution, the guide wheel has a plurality of partition plates, and the partition plates are distributed along the axial direction of the guide wheel.

[0018] As a further technical solution, it further includes a guide rod, the guide rod is arranged on the limit frame, the guide rod is arranged parallel to the screw rod, and the slider is slidably sleeved on the guide rod.

[0019] As a further technical solution, the roller surface of the fixed roller has a limit groove, and the limit groove is a semi-circular groove arranged in a spiral pattern.

[0020] As a further technical solution, it further includes a rib plate, and the rib plate is vertically arranged on the limit frame.

[0021] As a further technical solution, it further includes a tension wheel, and the tension wheel is rotatably arranged on the limit frame.

[0022] The working principle and beneficial effects of the present utility model are as follows:

[0023] In the present utility model, the guide wheel is rotatably arranged on the adjusting roller. The copper wire first enters the guide wheel through the through hole on the limit frame, is spirally wound on the guide wheel and then extends to the fixed roller, and is spirally wound on the fixed roller and then extends out from the through hole on the limit frame. The screw rod can drive the relative sliding between the slider and the limit frame, thereby changing the distance between the adjusting roller and the fixed roller. When the distance between the adjusting roller and the fixed roller increases, the tension on the wire on the adjusting roller and the fixed roller increases, and the wire is subjected to a tensile force and its diameter decreases. Compared with the conventional traction type wire drawing machine in the prior art, the change of the tension acting on the wire in a large copper wire drawing machine in the present application is more linear, and the acting points are evenly distributed at each position of the wire. Therefore, the diameter of the drawn wire is more uniform. Description of the Drawings
