Abstract

The utility model relates to a rolling slider device which comprises a slide strip and a slider; rolling bearings are symmetrically arranged on both sides of the slider, and are contacted with the slide strip in a rolling way; and the rolling bearings are arranged on a cylindrical pin which passes through the slider. The rolling slider device has a simple structure, and is easy to realize, an original linear bearing is replaced by the combination of the rolling bearings and the slider, so that the impact load bearing capability is improved, the service life of a slider part is prolonged, and the cost is reduced.

Description

The rolling slide block device

Technical field

The utility model relates to steel tube straightening machine, is specifically related to steel tube straightening machine subsidiary engine automatic loading and unloading device and uses the rolling slide block device.

Background technology

Present steel tube straightening machine basically all is an automatic loading/unloading, realizes through the automatic loading and unloading device of subsidiary engine, and the slider part of the automatic loading and unloading device of subsidiary engine adopts the ball linear bearing usually.The steel pipe material loading utilizes the cylinder transfer motion power that links to each other with connecting rod usually, drives many feeding platforms simultaneously and goes up and down, and holds up steel pipe and delivers on the linked transmission track through guide pad; Because effect of inertia can produce bounce-back by the bump track after steel pipe puts down, and can strike charging and discharging mechanism after the bounce-back; Therefore charging and discharging mechanism is produced horizontal impulsive force, and linear bearing is a kind of linear motion system, its bearing ball contacts with spool being; So maneuvering load is little, therefore frequently suffer side knock to cause damage easily, and regular well damage have influence on ordinary production; And it is higher to change the linear bearing cost, is unfavorable for enterprise operation.

The utility model content

The utility model provides a kind of rolling slide block device, the slider part that the has solved steel tube straightening machine subsidiary engine automatic loading and unloading device flimsy problem of load that withstands shocks.

For realizing above-mentioned purpose, adopt following technical scheme:

A kind of rolling slide block device comprises draw runner and slide block, and said slide block both sides are symmetrically installed with rolling bearing, and said rolling bearing rolls with draw runner and contacts.

As further prioritization scheme, said rolling bearing is installed on the straight pin that passes slide block.

The utility model is simple in structure, is easy to realize, adopts the combination of rolling bearing and slide block, substitutes original linear bearing, has improved the ability of the load that withstands shocks, and has prolonged the service life of slider part, has reduced cost.

Description of drawings

According to embodiment and accompanying drawing the utility model is done further explain below.

Fig. 1 is a ball linear bearing slide block sketch map;

Fig. 2 is the utility model structural representation;

Fig. 3 is the cutaway view at A-A place among Fig. 2;

Fig. 4 is the front view of part 3 among Fig. 2.

Among the figure:

1, draw runner; 2, linear bearing; 3, slide block; 4, rolling bearing; 5, straight pin.

The specific embodiment

Shown in Fig. 1 to 4, provided a specific embodiment of the utility model, Fig. 1 is the loading and unloading slider part that adopts linear bearing 2; Because the maneuvering load of linear bearing 2 is less; And when steel pipe loading and unloading operation, unavoidably linear bearing 2 being produced side knocks, its bearing ball is with axle and a little causes damage easily; Have influence on normal production, and replacement cost is higher.Fig. 2 to 4 is depicted as and adopts slide block 3 and four rolling bearings 4 to substitute linear bearing, and four rolling bearing 4 symmetries are installed on the straight pin 5 that passes slide block 3, rolls on draw runner 1 through four rolling bearings 4; Realize the up-down of feeding platform; Bear the lateral impact forces in the loading and unloading process by rolling bearing 4 and straight pin 5, not only prolonged the service life of slide unit, and rolling bearing 4 all adopts standard component with straight pin 5; With low cost, replacing and maintenance are all more convenient.

The utility model fitting tight, simple in structure being easy to again realized, reduced maintenance cost the service life of having improved the slider part of steel tube straightening machine subsidiary engine automatic loading and unloading device, improved production efficiency.

Claims

1. a rolling slide block device comprises draw runner and slide block, it is characterized in that, said slide block both sides are symmetrically installed with rolling bearing, and said rolling bearing rolls with draw runner and contacts.

2. a kind of rolling slide block device according to claim 1 is characterized in that said rolling bearing is installed on the straight pin that passes slide block.
