Description

Technical Field

[0001] The utility model relates to the technical field of wire drawing machines, in particular to a clamping structure for wire drawing machines. Background Art

[0002] A wire drawing machine, also known as a wire drawing machine or wire drawing machine, is a widely used piece of machinery in industrial applications. It is a machine that can draw thick metal wire into wire of desired thickness. It primarily deforms the metal material along the stretching direction through tension, thereby producing a thin metal wire of the desired specifications. Existing wire drawing machines typically clamp the wire by expanding the tensioning pulley to increase the tension of the wire, which is then wound onto the winding drum, achieving a tighter tension and better clamping force.

[0003] However, the above method has certain defects. Due to the transmission of the driving structure to the rope, the existing clamping structure cannot be adaptively adjusted according to the tension of the rope itself, so that the rope cannot be effectively clamped by the rotation of the winding wheel itself, so that the rope is relatively loose on the winding wheel. Since the existing wire drawing machine has no adaptive adjustment, the user is often required to judge by observation and then make manual adjustments. This method takes a long time in actual operation and cannot effectively control the tension of the rope, so that a better clamping effect cannot be achieved.

[0004] Therefore, in order to be able to achieve adaptive tension adjustment of the rope according to the tension of the rope itself, and thereby facilitate the winding wheel to better achieve the clamping effect of the rope through its own rotation, a clamping structure for a wire drawing machine is proposed, which can achieve a better clamping effect on the rope without human intervention, thereby solving the technical problems existing in the above-mentioned prior art.

The rear end of the pulley transmission shaft is connected to the driving structure, and the pulley transmission shaft passes through the mounting sleeve. The first guide wheel is installed at the front end of the pulley transmission shaft, and a mounting plate is installed on the surface of the mounting sleeve. An opening is opened on the surface of the mounting plate, and the mounting block is installed on the rear side of the mounting plate.

[0008] Furthermore, a connecting plate 2 is installed on the right side surface of the wire drawing machine body, and a guide wheel is installed at the end of the connecting plate 2.

[0009] As a preferred technical solution, grooves are provided on both sides of the sliding seat, a mounting seat is installed in the groove, a ball is movably installed in the mounting seat, and the ball contacts the inner side of the opening provided on the surface of the mounting plate.

[0013] Compared with the prior art, the present invention provides a clamping structure for a wire drawing machine, which has the following beneficial effects:

[0014] 1. This clamping structure mainly drives the movable plate to rotate through the tensioning force of the rope itself. During rotation, it is detected by the conductive plastic potentiometer through the action of the gears and the transmission teeth, and the transmission ratio of the machine is detected. When the detected value is too large, it means that the tensioning force is large. If the detected value is too small, the tensioning force is small. If any of the phenomena occurs, the motor drives the threaded shaft to rotate, and then drives the sliding seat to move at the opening, so that the distance between the second guide wheel and the first guide wheel is adjusted, and then the tensioning force of the rope is adjusted. When the tensioning force reaches a moderate level, the rotation of the winding wheel itself can effectively improve the clamping effect of the rope achieved by the rotation of the winding wheel itself, and thus can be achieved without human intervention, which solves the problem that the clamping structure in the existing wire drawing machine cannot realize the adjustment of the adaptive tensioning force according to the tensioning force of the rope itself, and thus cannot achieve the clamping effect of the rope by the rotation of the winding wheel itself.

At this time, the line rope is tensioned by the line rope itself, and its movable plate 10 will be adjusted accordingly. At this time, the gear relationship between the gear 16 and the transmission tooth 24 is detected by the conductive plastic potentiometer 17.
