Abstract

The utility model discloses a tension control device of a wire cutting machine. The tension control device of the wire cutting machine is characterized by comprising a rope winding disc, a heavy punch, a swing arm and a pinch roller, wherein the rope winding disc is arranged in a rotating manner, and connected with the heavy punch for rotating the rope winding disc, the swing arm is arranged in a swinging manner, and connected with a rope connected on the rope winding disc, and the pinch roller is connected on the swing arm and compresses electrode wires arranged between a wire storing cylinder and upper and lower wire arm outlets of the wire cutting machine. The tension control device of the wire cutting machine is simple in structure and has constant tension control.

Description

A kind of tenslator of wire cutting machine

Technical field

The utility model relates to a kind of linear cutting equipment, is specifically related to a kind of tenslator of wire cutting machine.

Background technology

The wire electrode of wire cutting machine is in continuous cutting and continuous use; Because the influence of factors such as variations in temperature, wire electrode wearing and tearing, the tightening force of wire electrode can be lost gradually, will greatly influence the crudy of line cutting like this; So the constant tension that tenslator comes the control electrode silk must be set; In the prior art, have by spring thrust, the tenslator that adds spring thrust by the cylinder straight-line guidance is arranged, but all have complex structure, the inconstant defective of tension force.

Summary of the invention

In view of the problem that present known technology exists, the technical problem that the utility model will solve is the wire cutting machine tenslator that is to provide a kind of simple in structure, permanent Tension Control.

For solving the problems of the technologies described above, the utility model takes following technical scheme to accomplish:

A kind of tenslator of wire cutting machine; It is characterized in that: this tenslator comprises around rope dish, weight, swing arm and pinch roller; Around the rotatable setting of rope dish, be connected with the said weight that makes around the rotation of rope dish around Suo Panshang, swing arm can be swung setting; Swing arm is connected with the rope that is connected on the rope dish, said pinch roller be connected in the swing arm to be located at the wire cutting machine wire storage tube and up and down the wire electrode between the outlet of silk arm compress.

The gravity effect of the utility model through weight makes around the rope dish rotates; Through rope pulling swing arm, the swing arm swing makes pinch roller compress the tension force of control electrode silk to wire electrode, because the gravity of weight is constant around the rope dish; So the pressure through pinch roller acts on the wire electrode is also constant; Thereby reach the purpose of permanent Tension Control, simultaneously, the structure of the utility model is very simple.

Description of drawings

The utility model has following accompanying drawing:

Fig. 1 is the structural representation of the utility model.

The specific embodiment

Accompanying drawing has been represented the technical scheme and the embodiment of the utility model, combines accompanying drawing to further describe each relevant details and operation principle thereof of embodiment below again.

With reference to accompanying drawing 1; The tenslator of this kind wire cutting machine; Comprise around rope dish 6, weight 10, top link 4, following swing arm 8, pinch roller 3 and pinch roller 9; Around rope dish 6 rotatable settings, on rope dish 6, be connected with and make the said weight 10 that rotates counterclockwise around the rope dish, swing arm can be swung setting; Top link 4 is connected with the rope 5 that is connected on the rope dish; Following swing arm 8 is connected with the rope 7 that is connected on the rope dish, and the swinging end that said pinch roller 3 is connected top link 4 compresses the wire electrode 2 that is located at wire cutting machine wire storage tube 1 and go up between the outlet of silk arm, and the swinging end that said pinch roller 9 is connected down swing arm 8 compresses being located at wire cutting machine wire storage tube 1 and following arm wire electrode 11 between exporting.

After the utility model is installed; Because the gravity effect of weight rotates counterclockwise around the rope dish, through rope pulling pumping arm action; The swing arm swing makes pinch roller compress the tension force of control electrode silk to wire electrode; Because the gravity of weight is constant,, thereby reach the purpose of permanent Tension Control so the pressure that acts on the wire electrode through pinch roller is also constant.

Claims

1. the tenslator of a wire cutting machine; It is characterized in that: this tenslator comprises around rope dish, weight, swing arm and pinch roller; Around the rotatable setting of rope dish, be connected with the said weight that makes around the rotation of rope dish around Suo Panshang, swing arm can be swung setting; Swing arm is connected with the rope that is connected on the rope dish, said pinch roller be connected in the swing arm to be located at the wire cutting machine wire storage tube and up and down the wire electrode between the outlet of silk arm compress.
