A fully automatic cold rolling mill

Abstract

The invention discloses a full-automatic cold-rolling mill and relates to the field of cold-rolling mills. The full-automatic cold-rolling mill solves the problems of low automatic degree, low production efficiency and the like of an existing cold-rolling mill. The full-automatic cold-rolling mill comprises an automatic feeding device, a rotary feeding device, a blank tube rolling device, an automatic finished product discharging device and a control unit used for controlling the coordination work and communication between the devices, the automatic feeding device is capable of feeding automatically, measuring the length of the blank tube and feeding the measured blank tube to the rotary feeding device, the control unit regulates the running distance and fast forward distance of a blank tube clamping and feeding trolley on the rotary feeding device according to the data, and finally the blank tube is sent to the blank tube rolling device; after finishing rolling, a finished tube can be automatically discharged to a finished product zone. Through automatically regulating the running distance and fast forward distance of the feeding trolley, the full-automatic cold-rolling mill can realize continuous feeding in the feeding stage of the blank tube rolling, the manual intervention to the feeding trolley and machine interruption are not needed, the full-automatic production is realized, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of cold rolling mills, in particular to a fully automatic rolling mill that can realize continuous feeding of billet tubes and uninterrupted work of the cold rolling mill in the feeding stage of billet tube rolling without manual control and intervention of billet tube feeding. cold rolling mill. Background technique [0002] As a process equipment for cold rolling billet tubes, cold rolling mills are widely used in the pipe processing industry. However, most of the cold rolling mills in the prior art are not highly automated, and most of the automatic control is automatic. The two processes of feeding and automatic unloading, such as the invention named "Cold Rolling Mill with Automatic Feeding Device" and patent No. 201220251961.6 announced by the State Intellectual Property Office on December 19, 2012, the cold rolling The automatic control realized is only in the feeding process. Although it overcomes t...

[0002] As a process equipment for cold rolling billet tubes, cold rolling mills are widely used in the pipe processing industry. However, most of the cold rolling mills in the prior art are not highly automated, and most of the automatic control is automatic. The two processes of feeding and automatic unloading, such as the invention named "Cold Rolling Mill with Automatic Feeding Device" and patent No. 201220251961.6 announced by the State Intellectual Property Office on December 19, 2012, the cold rolling The automatic control realized is only in the feeding process. Although it overcomes the defect of manual feeding in the traditional cold rolling mill, but in the process of rolling the billet tube, due to the uncertain length of the billet tube, when the feeding is completed, Since the feeding trolley can only withstand the rear end of the tube billet, the feeding trolley must be returned to the original position (reset), and the next tube blank to be loaded into the core rod enters the feeding trolley, and then clamped After the core rod is clamped by the device, the feeding trolley starts to feed, so there is a period of auxiliary preparation time for the feeding trolley to retreat, loading, clamping, etc., so the previous billet tube must wait until it is completely rolled before the next billet tube Or manually control the rolling distance between the previous billet tube and the next billet tube during the rolling process of the billet tube, so that the cold rolling mill cannot work continuously

Therefore, it not only increases a lot of labor costs, but also reduces the production efficiency.
