Abstract
The utility model discloses an upper blade adapter guiding device of a plate shearing machine, comprising a guide track and a roller, wherein, the guide track is arranged on the external both sides of the upper blade adapter; four rollers are arranged in a guide track groove symmetrically; two bottom rollers are fastened to a frame by a supporting shaft; two upper rollers are arranged on the frame by an eccentric shaft and a flexible shaft; the upper blade adapter can not bear preload in the frame and can move limberly. The utility model has the advantages of simple structure, low cost, convenient adjustment and high efficiency.
Description
The utility model relates to metal forming machinery, is the guider of plate shearing machine upper tool post.
The lock formula plate shearing machine of at present domestic and international manufacturer production, the guider of upper tool post is generally rail plate or rolling guide.The rolling guide that is adopted all is again a bikini, be guide rail with roller between be at 3 and contact, roller is arranged on the frame, upper tool post is provided with guide pass, the both sides of upper tool post are all tightly clamped by three rollers on the frame, wherein upper and lower two roller wheel bearings are at the upper tool post rear portion, and middle roller wheel bearing is in the upper tool post front portion.For making two rollers that upper tool post is close to the rear portion when zero load or the load all the time to guarantee kinematic accuracy, be provided with elastic support make in roller be bearing in the upper tool post front portion tightly.Like this, have bigger preload between roller and guide rail all the time, this just causes abrasion to increase, and the size of member strengthens.Because bigger preload exists, when adjusting gap blade, change the position of upper roller, a cover force-increasing mechanism just must be set just can adjust operation.
The purpose of this utility model is: a kind of simple in structure, guider of sliding freely, reducing abrasion plate shearing machine upper tool post easy to adjust is provided, and it has cancelled original elastic support and force-increasing mechanism, is a kind of two point form rolling guide.
To achieve these goals, the guider of plate shearing machine upper tool post of the present utility model is made up of guide rail and roller two parts.Guide rail is arranged on the both sides external of upper tool post, and the guide rail of every side constitutes by " L " type guide pass and guide rail cover plate.Roller has four, be symmetrically distributed in the guide-track groove of both sides, wherein, two bottom rollers are arranged on the frame by bolster separately, two upper rollers then eccentric support axle by separately are arranged on the frame, by the central siphon of flexibility two eccentric support axles are joined together.This guider does not have elastic support, does not have preload, and roller has little clearance in guide rail, and for satisfying the scissors required precision, this gap generally is controlled in the 0.05mm, and upper tool post moves in frame flexibly, the shear efficiency height.Owing to do not have preload,, when needing to adjust gap blade, when frame one side rotation eccentric support axle is adjusted, just easily, do not needed force-increasing mechanism when the steel plate of shearing different-thickness.
Characteristics of the present utility model are: simple in structure, with low cost, easy to adjust, and the shear efficiency height.
Below embodiment of the present utility model is described, accompanying drawing is structural representation, has shown upper tool post and roller, among the figure:
1-blade 2-bolster 3-roller
4-guide rail cover plate 5-bolt 6-eccentric support axle
7-upper tool post 8-central siphon
Knife rest is that the A3 steel plate is welded into.Roller and guide rail cover plate adopt GCr15 steel material, quenching C48.Be the surface abrasion resistance that the guide rail that makes upper tool post contacts with roller, a GCr15 steel plate, quenching C48 have installed in this place.
Guider of the present utility model adopts on Q11Y-6.35 * 3100A type hydraulic shearing machine.It also can adopt for the sliding part of other metal forming machinerys.
Claims (1)
