Novel safety bolt of sliding block of press machine

Abstract

The invention discloses a novel safety bolt of a sliding block of a press machine. The novel safety bolt comprises a positioning plate, a positioning block, a first connecting plate, a second connecting plate, a connecting pin shaft and a bolt column, and is characterized in that mounting holes, fixing blocks and a limiting block are arranged on the positioning plate, a bearing shaft is arranged between the fixing blocks, a mounting hole, a buffer pad and a limiting pin are arranged on the positioning block, one end of the first connecting plate is connected to the bearing shaft, the other end of the first connecting plate is provided with a connecting ring, one end of the second connecting plate is provided with a connecting ring, the other end of the second connecting plate is provided with a bolt sleeve, the connecting pin shaft penetrates through the connecting ring of the first connecting plate and the connecting ring of the second connecting plate respectively, and the bolt column penetrates through the bolt sleeve. According to the novel safety bolt, a shaft shoulder is arranged on the bolt column, a spring is arranged between the shaft shoulder and the bolt sleeve, and part of impact force generated by sudden drop of the sliding block can be buffered through the spring.

Description

technical field [0001] The invention relates to the technical field of a press, in particular to a novel safety bolt for a slide block of a press. Background technique [0002] The press is one of the commonly used equipment in the machining process. When the press breaks down, the slider of the press needs to be supported to prevent it from sliding down, so that the operator can perform maintenance and repair of the press. The traditional method is mostly in the There is a safety bolt composed of columns between the press slider and the press platform to fix the slider. However, there is no fixed position for the columns in this way. When the press fails, the operator needs to find the columns before pushing it up The slider is lifted, which reduces the work efficiency. The position of the column in the press is inconvenient to adjust, and the column cannot be in the best position, which reduces the bearing capacity of the column. When the slider drops suddenly, there is n...
