Self-lubricating type stamping mold guide column special for punching machine

Abstract

The invention relates to the field of mold guide columns, in particular to a self-lubricating type stamping mold guide column special for a punching machine. The stamping mold guide column comprises alower shaft shoulder and an outer guide sleeve; mounting holes are formed in the inner side of the lower shaft shoulder, and a column body is movably installed on the outer side of the upper end of the lower shaft shoulder; a spring is arranged on the outer surface of the column body; the outer side of the lower end of the outer guide sleeve is fixedly provided with a steel ball guide sleeve, andsteel balls are movably installed on the inner surface of the steel ball guide sleeve; and an upper shaft shoulder is fixedly installed on the outer side of the upper end of the outer guide sleeve. According to self-lubricating type stamping mold guide column special for a punching machine, first oil separation outlets, second oil separation outlets, an oil guide pipe and a guide sleeve inner wall are arranged, the guide sleeve inner wall is not attached to the outer guide sleeve so that a cavity is formed, oil can be stored, oil can be discharged at the same time through the oil separation outlets which are alternately installed in a staggered mode, and therefore the lubricating effect is improved, multiple oil injection grooves are replaced by the single oil guide pipe, production costof the column body is reduced, and better application prospects are brought.

Description

technical field [0001] The invention relates to the field of mold guide columns, in particular to a self-lubricating stamping mold guide column dedicated to punching machines. Background technique [0002] The guide post is a guide element used in combination with components in the mold to ensure that the mold can move and guide the mold stroke with precise positioning. The large amount of use greatly enhances the durability and replaceability of the guide post in terms of guiding performance. The guide post and components are composed of the outer guide post assembly and the inner guide post assembly. They have a beautiful metallic luster and are cylindrical with shoulders. Generally, there are oil grooves. The number of oil grooves increases with the length of the guide post. The oil groove with the most limit is generally Eight, ensuring the lubrication of the guide post is a favorable prerequisite for maintaining the stable and efficient work of the punching machine. ...

AI Technical Summary

Problems solved by technology

[0003] The existing down-the-hole drilling rigs have certain disadvantages in use. The cylinder adopts multiple oil tanks to conduct oil, the effect is not obvious enough, and the production of the cylinder is more troublesome. Oil injection needs to be injected from multiple angles, which increases the workload and difficulty of manual oil injection. The integrated design of the outer guide sleeve has no internal cavity, no supporting equipment for oil storage, and frequent manual oil injection has brought certain influences. Therefore, we propose a self-lubricating stamping die guide column for punching machines
