Description

Tightness adjusting device for wire drawing machine

Technical Field

The utility model belongs to the technical field of copper line processing technique and specifically relates to indicate an elasticity adjusting device that wire drawing machine was used.

Background

In the production process of thin copper wire, need draw rough copper wire through greatly, well draw and draw for a short time and reduce its diameter gradually, well draw and need send the copper wire to use in little wire drawing machine around the take-up reel after accomplishing, and traditional little wire drawing machine import department only is equipped with fixed guide pulley, at the unwrapping wire in-process, because the elasticity degree of take-up reel, coiling radius etc. differ, make the smooth and easy degree that the copper wire is qualified for the next round of competitions also differ, if the unwrapping wire speed of take-up reel is greater than the speed of acting as go-between of wire drawing machine, will make the copper wire take place lax phenomenon, the copper wire can break away from fixed guide pulley when getting into the wire drawing machine import, thereby cause the copper wire to be scratched and appear substandard product or waste product, influence the quality of product.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

An object of the utility model is to provide an elasticity adjusting device that wire drawing machine was used can adjust the elasticity that the copper line entered into the wire drawing machine, guarantees that the copper line is all the time on the guide pulley, avoids the copper line to be scratched, guarantees the quality of product. In order to achieve the above purpose, the utility model adopts the following technical scheme:

(II) technical scheme

The utility model provides an elasticity adjusting device that wire drawing machine was used, includes supporting seat and guide pulley, the guide pulley is fixed through the pivot on the supporting seat, both sides are equipped with the arc hole of bending down on the supporting seat, the pivot card is established just pivot diaxon end extends the arc hole on the arc hole, the supporting seat both sides all are equipped with the mounting hole, two the downthehole card of mounting hole is equipped with the bolt axle, be connected with the spring between bolt axle head and the pivot axle head, the mounting hole arrives the distance of arc hole highest end is greater than the distance of mounting hole to arc hole lowest.

Furthermore, the two shaft ends of the rotating shaft and the bolt shaft are provided with fixing holes, and lengthened cotter pins are installed on the fixing holes.

Furthermore, annular grooves are formed in two shaft ends of the rotating shaft and the plug pin shaft, and the spring is clamped in the annular grooves.

(III) advantageous effects

Compared with the prior art, the utility model has obvious advantages and beneficial effects, particularly, the copper wire leads the guide wheel to be at the highest end of the arc-shaped hole through the pulling force under the normal state of the utility model, and the spring is stretched at the moment; under the state of lax, thereby the spring makes the guide pulley make the copper line by the flare-out along arc hole gliding toward drawing back, can adjust the elasticity that the copper line enters into the wire drawing machine, guarantees that the copper line is on the guide pulley all the time, avoids the copper line to be scratched, guarantees the quality of product.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

The present invention will be further described with reference to the accompanying drawings and the detailed description.

Referring to fig. 1 and 2, a tightness adjusting device for a wire drawing machine includes a supporting seat 1 and a guide wheel 2, the guide wheel 2 is fixed on the supporting seat 1 through a rotating shaft 3, arc-shaped holes 11 bent downward are provided on both sides of the supporting seat 1, the arc-shaped holes 11 have better buffering effect than a common vertical hole, the rotating shaft 3 is clamped on the arc-shaped holes 11, two shaft ends of the rotating shaft 3 extend out of the arc-shaped holes 11, mounting holes 12 are provided on both sides of the supporting seat 1, a latch shaft 4 is clamped in the two mounting holes 12, a spring 5 is connected between the shaft end of the latch shaft 4 and the shaft end of the rotating shaft 3, the distance from the mounting hole 12 to the highest end of the arc-shaped holes 11 is greater than the distance from the mounting hole 12 to the lowest end of the arc-shaped holes 11, which is equivalent to a quarter of an ellipse, the highest end of the arc-shaped holes 11 is located at the end of a long shaft, and the lowest end of the arc-shaped holes 11 is located at the end of a short shaft, the mounting hole 12 is in the centre of the ellipse.
