Method for Automatically Changing Steel Wires of Blank Cutting Machine

Abstract

The invention provides a method of automatically replacing a steel wire for a raw brick cutting machine. According to the method, when a steel wire rope on a raw brick cutting table meets a replacing condition, a first steel wire rope holding device and a second steel wire rope holding device are controlled to release the steel wire rope, and a second steel wire rope winding shaft is driven to wind until a new steel wire rope is located on the raw brick cutting table; then the first steel wire rope holding device and the second steel wire rope holding device are driven in sequence to tighten the new steel wire rope, and the tightening motion of the first steel wire rope holding device is 0.05 s to 0.5 s earlier than the tightening motion of the second steel wire rope holding device. By means of the scheme, the raw brick cutting machine can work without stop around the clock, the efficiency of making bricks is greatly improved, and the cost is saved. The tightening motion of the first steel wire rope holding device is 0.05 s to 0.5 s earlier than the tightening motion of the second steel wire rope holding device, and the new steel wire rope can be tensioned exactly.

Description

technical field [0001] The invention relates to the technical field of brick making machinery, in particular to an automatic wire changing method for a blank cutting machine. Background technique [0002] The blank cutting machine is an important part of the brick making equipment. The failure mode of the steel wire used in the blank cutting machine is mainly fracture when cutting the mud strip. On the one hand, the fracture is caused by the friction between the steel wire and the mud strip for a long time; During the cutting process, it encounters hard small particles and suddenly breaks. The traditional blank cutting machine needs to stop the operation of the entire brick making system when the steel wire breaks, and then manually replace the broken blank cutting steel wire. This not only greatly reduces the efficiency of brick making, but also wastes the electric energy consumed by the motor idling. [0003] At present, there are some wire changing devices on the market...

Problems solved by technology

This not only greatly reduces the brick-making efficiency, but also wastes the electric energy consumed by the motor idling.

[0003] There are some steel wire changing devices on the market at present, such as Chinese patent 200820029808.2, the invention name is a new type of automatic billet cutting machine, which is characterized in that the purpose of changing the steel wire is achieved by sliding the billet steel wire frame back and forth on the frame. This scheme is not only inconvenient to operate, It requires a lot of manpower, and when cutting half of the blank steel wire, specifically, half of the steel wire is in the mud strip, and the cutting is not complete, so the blank steel wire rack cannot be moved at all, so the purpose of changing the steel wire cannot be achieved
