Problems solved by technology

It is characterized by no head and tail material, low cost, but no straightening to reduce the side bending process. The side bending is generally less than 2mm / m, which can only meet the requirements of general users. If it is less than 0.5mm / m, it needs to be equipped with a straightening machine. It will also increase the process waste at the head and tail. Like the previous drawing machine, the material waste is large and the cost is high.

Embodiment Construction

[0024] For the convenience of description, the present invention defines: "head side" is the direction in which the copper bar blank moves, "tail side" is its opposite direction, "left side" is the direction of the left hand side when facing the head side and back to the tail side, " Right” is the opposite direction to the left, such as image 3 shown.

[0025] The copper bar drawing and straightening equipment of the present invention comprises a drawing die 2, a tire puller 3, a reciprocating section cutting machine 4, a bending measuring mechanism 5, a length fixing mechanism 6, a thermoplastic packaging system 7 and a controller 8 . The controller 8 adopts the field bus to control the intelligent automatic drawing and straightening of the entire production line, cutting to length, measuring and straightening.

[0026] The drawing die 2 is connected with the servo motor, and the servo motor is connected with the controller 8. Under the control of the controller 8, the dra...

Abstract

The invention relates to drawing and straightening equipment of copper bars. The drawing and straightening equipment comprises a drawing die capable of being deflected, a traction machine, a cutting machine, a curve measuring mechanism and a controller. The drawing die is connected with a servo motor and can be controlled by the controller to be deflected by an angle. The curve measuring mechanism is composed of two midpoint distance measurement sensors and two locating devices on the two sides of the midpoint distance measurement sensors. The two locating devices make contact with the copper bars and locate the section, located between the two locating devices, of the copper bars. The two midpoint distance measurement sensors are symmetrically arranged on the left side and the right side of the copper bars, and the peaks of the front ends of the midpoint distance measurement sensors are located on the midpoints of the connecting lines between the contact points, making contact with the copper bars, of the two locating devices. According to the drawing and straightening equipment, the data collected by the curve measuring mechanism are fed back to the controller, the controller drives the drawing die to be deflected by a small angle so that lateral bending can be reduced, correction is completed in the drawing process, additional straightening equipment and processes are not needed, and the quality and the production efficiency are improved.

Description

technical field [0001] The invention belongs to the field of copper processing, and in particular relates to a drawing and straightening device used in the processing of copper bars. Background technique [0002] At present, the mainstream copper bar processing and production technology is to draw up the billet bar, continuously extrude into a row of billets, and the row of billets must be straightened and cut to length, and the finished product is packaged. During the drawing process of the copper bar, due to uneven material, friction, etc., one side will elongate more and one side will elongate less, resulting in the so-called "side bending". [0003] At present, a hydraulic drawing and straightening machine is used to draw, cut to length, straighten and remove the head and tail, and then pack and leave the factory. The feature of this hydraulic drawing and straightening integrated machine is that three processes are completed on one drawing machine: drawing, length cutti...
