Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1 and 2, the balanced lifting structure of the door plate of the cutting room of the multi-wire cutting machine of the present invention comprises a lifting door plate 1, a door frame upright post 3, a lifting guide rail assembly 2 and a coil spring assembly 4; the edges of the left side and the right side of the lifting door panel 1 are assembled with the lifting guide rail assembly 2; the lifting guide rail assembly 2 is fixedly arranged on door frame upright posts 3 arranged on the left side and the right side of the lifting door plate; the coil spring assembly 4 is mounted between the lifting door panel 1 and the lifting guide rail assembly 2.

Referring to fig. 1, 2, 5 and 6, in the balanced lifting structure of the door plate of the cutting room of the multi-wire cutting machine of the present invention, the coil spring assembly 4 includes a mandrel 4-2, a coil spring body 4-1 and two side baffles 4-4; the mandrel 4-2 is positioned between the baffle plates 4-4 at the two sides, is assembled with the lifting guide rail assembly 2 through a pin shaft 4-3 and is installed at the upper end of the lifting guide rail assembly 2, an oil-free lubrication bearing 4-5 is arranged between the mandrel 4-2 and the pin shaft 4-3, the coil spring body 4-1 is wound on the mandrel 4-2, and the tail pulling end of the coil spring body is fixed on the inner side wall of the lifting door plate 1 through a screw 5.
