End pointing rolling machine for aluminum wire drawing

Abstract

The invention relates to the technical field of pointing rolling machines, and discloses an end pointing rolling machine for aluminum wire drawing. The end pointing rolling machine comprises a supporting plate, wherein supporting legs are fixedly connected to the four corners of the lower surface of the supporting plate, supporting columns are fixedly connected to the four corners of the upper surface of the supporting plate, and a transverse plate is fixedly connected to the top ends of the supporting columns; and a pointing device is arranged on the upper surface of the transverse plate, anadjusting device is arranged on the upper surface of the pointing device, a refrigerating device is arranged on the right side of the upper surface of the supporting plate, and the refrigerating device comprises a refrigerating barrel. According to the end pointing rolling machine for aluminum wire drawing, refrigeration is conducted through an arranged semiconductor chilling plate, cold air is transmitted through a cold guide block to refrigerate cooling liquid in the refrigerating barrel, the cooling liquid can still keep the refrigeration effect after being used for a long time, and the situation that the cooling effect is reduced is avoided, so that the refrigeration effect of the end pointing rolling machine is guaranteed, and the service life of the end pointing rolling machine is ensured.

Description

technical field [0001] The invention relates to the technical field of pointing machines, in particular to an end pointing machine for aluminum wire drawing. Background technique [0002] The pointing machine is an auxiliary equipment for copper, aluminum, and iron wire drawing equipment. It is mainly composed of rolls, reduction drives, etc., and is used for pointing operations before drawing various metal wires. After passing through the drawing die hole, the material can be drawn and processed. During the long-time pointing operation of the existing pointing machine, the roll will heat up, and most of the existing pointing machines are not equipped with cooling structures. [0003] For example, the Chinese Patent Publication No. CN107745014A provides a pointing machine for copper wire drawing, which is basically described as follows: it includes a pointing machine body and a feeding device, the pointing machine body includes a frame, and the top of the frame is installed ...

Problems solved by technology

[0003] For example, the Chinese Patent Publication No. CN107745014A provides a pointing machine for copper wire drawing, which is basically described as follows: it includes a pointing machine body and a feeding device, the pointing machine body includes a frame, and the top of the frame is installed with rollers. The upper roll and the lower roll are fixed on the roll mounting seat through bearings, and the feeding device is installed on the inlet side of the upper roll and the lower roll. The invention has cooling chambers in the upper roll and the lower roll, which is convenient for the upper roll and the lower roll. The cooling of the lower roll can work for a long time and improve the work efficiency, but the cooling effect of the device is still poor. The device cools the upper roll and the lower roll by recycling the cooling liquid. After the cooling liquid is used for a long time The cooling effect gradually deteriorates, thereby reducing the cooling effect on the upper and lower rolls, thereby reducing the working efficiency of the device
