Modification of front gauge interlock mechanism of

Beiren J2205 machine front gauge interlock mechanism transformation

this paper will briefly introduce that beiren J impact testing machine will be more affected. 1. The problems occurred in the actual work of 2205 machine and the solutions:

according to the description of beiren J2205 offset press front gauge interlock mechanism, when the paper feeding mechanism is crooked, broken, and not in place, the interlock mechanism should work. At this time, the paper feeding machine stops, the front gauge does not lift, and the paper feeding teeth do not pick up the paper, The pressure closing mechanism has high pressure and the whole machine idles at low speed

after the installation and commissioning of a J2205 offset press, the interlock mechanism of the front gauge is sometimes good and sometimes bad. The paper feeder stops when the sheet is tilted on the same day, and the front gauge does not lift up, but the paper delivery teeth still hold the paper in their mouths, and the paper is rotten and handed over. Therefore, the rubber is often damaged by rotten paper. As a result, the maintenance personnel were asked to repair it. At that time, the interlock mechanism was increased by 9.6%, and the long hole of the first connecting rod (n73-70503) was spot welded. After grinding, the problem was solved

however, after a period of time, the same problem of inspecting the above experimental microstructure on the axiovert200mat optical microscope reappears. If we weld again according to the previous method, the problem can be solved, but it is too troublesome to repair welding often. We have made an in-depth analysis on this problem. The technical name and technical parameters try to improve to make it adjustable, that is, when the long hole or pin (n73-70501) of the connecting rod is worn, it can be made up by adjustment. The specific improvement methods are as follows

(1) expand the long hole on the connecting rod (n73-70503) to ensure that it can be put into the tool for adjustment

(2) drill a small hole with a diameter of 2mm at the position where the pin (n73-70501) slides back and forth in the long hole of the connecting rod. And set into a screw hole (3mm), and then install 1 screw and 1 nut. The tail of the screw is made into a long mouth for adjustment with a screwdriver. In this way, it can be adjusted and locked, which is much more convenient

(3) near the front gauge shaft (n73-70204), that is, at the notch on the curve block (n73-70204) in the interlock mechanism, there is a long back hill rod. Grind its end half to make it eccentric, which can also be adjusted conveniently. This paper will briefly introduce the problems in the actual work of beiren J2205 machine and the solutions:

according to the manual of the interlocking mechanism in front of beiren J2205 offset press, when the paper feeding mechanism has skew sheets, broken sheets, and is not in place, the interlocking mechanism should work. At this time, the paper feeding machine stops, the front gauge does not lift, the paper feeding teeth do not hold the paper, the pressure closing mechanism is high, and the whole machine idles at low speed

We have made an in-depth analysis on this problem and tried to improve it so that it can be adjusted, that is, when the long hole or pin (n73-70501) of the connecting rod is worn, it can be compensated by adjustment. The specific improvement methods are as follows

(1) expand the long hole on the connecting rod (n73-70503) to ensure that it can be put into the tool for adjustment

(2) drill a small hole with a diameter of 2mm at the position where the pin (n73-70501) slides back and forth in the long hole of the connecting rod.
