Abstract

The utility model discloses a slider guiding device of a press machine, which belongs to the technical field of press machines. The utility model comprises a guide post and a guide sleeve, wherein the guide post is sheathed in the guide sleeve, a plurality of steel balls are arranged between the guide post and the guide sleeve, the excircle surface of the guide post and the surface of the inner circle of the guide sleeve are provided with a plurality of corresponding axial rolling slots, the axial rolling slots are uniformly distributed in the circumferential direction, the steel balls are matched with the axial rolling slots and the arranged among the axial rolling slots on the guide post and the guide sleeve. When the utility model is operated, the guide post and the guide sleeve form a relative slide, the steel balls roll in the axial rolling slots for supporting and guiding, the roller balls and the rolling slots form line contact, the contact surface is large, the utility model can bear a larger load and the motion of the steel balls in the axial rolling slots is flexible. The utility model can be used for press machines, and has the advantages of strong bearing capacity and good guide characteristic.

Description

A kind of press ram guider

Technical field

The utility model relates to a kind of forcing press, particularly the guider of press ram.

Background technology

In the prior art, the guider that a kind of press ram is arranged, mainly constitute by guide pillar, guide pin bushing and steel ball etc., described guide pillar and press ram position relative fixed, guide pin bushing and fuselage fix, and guide pin bushing is socketed on the guide pillar, some steel balls are arranged between the guide pillars and bushes, when the guide pillars and bushes relative motion, steel ball rotates, and plays supporting and guide effect; Because the cylindrical of guide pillar and the interior circle of guide pin bushing are smooth cylindrical surface, steel ball is contacted for point with both, its contact area is little, and therefore, its bearing capacity is poor.

The utility model content

The purpose of this utility model provides a kind of guider of press ram, makes its guiding good, and bearing capacity is strong.

The purpose of this utility model is achieved in that a kind of press ram guider, comprise guide pillars and bushes, described guide column sleeve is connected in the guide pin bushing, be provided with some steel balls between guide pillar and the guide pin bushing, the outer round surface of described guide pillar and the internal circular surfaces of guide pin bushing are provided with some corresponding axial slot rollings, described some axial slot rollings are along circumferentially evenly distributing, and steel ball is suitable and be positioned at axial slot rolling on the guide pillars and bushes with axial slot rolling.

In the utility model when work,, guide pillars and bushes slides relatively, and steel ball is axially rolling in the slot rolling, plays supporting and guide effect, and for line contact, its contact-making surface is big, can bear bigger load between ball and the slot rolling, and steel ball moves flexible in axial slot rolling.The utility model can be applicable on the forcing press, and it is strong to have bearing capacity, the advantage that guidance quality is good.
