Abstract
The invention discloses a bending roller extension bar of a flat plate structure. Grooves are arranged on side faces of a flat plate, a roller bearing combined device is arranged in each groove. By the aid of the roller bearing combined devices arranged on the side faces of the flat plate of the bending roller extension bar, operation of taking out pipes subjected to bending changes from existing sliding friction into rolling friction, friction force among machined parts and the side faces of the flat plate is reduced greatly, service life of the bending roller extension bar is prolonged, production cost is lowered, and production efficiency is improved.
Description
Technical field
The present invention relates to the metalworking technology field, especially a kind of bending roller extension bar.
Background technology
When sheet metal processing long size pipe or square tube and other closed profiles, mostly adopt bender equipment, and the bending roller extension bar 2 that uses in existing bender 1 structure is the Flat Sluice plate structure, as shown in Figure 1; When cylinder or square steel machine, workpiece 3 basic formings, a kind of mode is to keep a slit than the large wide seam of bending roller extension bar 2 thickness, conveniently takes off from bending roller extension bar 2, goes the follow-up processing typing of healing up again; But because this slit is less more favourable to following process, another kind of mode is to allow the thickness of gap width less than bending roller extension bar 2, but when the section bars such as the large wall thickness of processing, small-bore, Materials with High Strength, this must cause the both sides in this slit and the both sides plane contact of bending roller extension bar, because the frictional force on both sides, slit and bending roller extension bar plane is too large, Special Equipment need to be set to be pulled and could take out, and the plate surface damage to bending roller extension bar is larger, cause production cost to increase, efficient is lower.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of bending roller extension bar, frictional force is little, convenient to remove between workpiece and its plate face.
In order to realize the foregoing invention purpose, the invention provides following technical scheme: a kind of bending roller extension bar, be slab construction, be provided with groove in this dull and stereotyped side, be provided with the roller bearing composite set in this groove.
Further, be equipped with the roller bearing composite set in two sides of flat board.
Further, this roller bearing composite set is made of bearing and cylindricality roller, and this bearing is made of bearing end seat and C profile shaft bearing sleeve, and cylindricality roller two ends are erected on the bearing end seat, and mid portion is embedded in the C profile shaft bearing sleeve; This cylindricality roller is radially gone up part and is stretched out this C profile shaft bearing sleeve.
Further, be embedded with several interior rollers and interior roller in the inwall of this C profile shaft bearing sleeve in conjunction with bar.
Further, this bearing end seat is provided with the ball that mates with cylindricality roller end.
Further, this bearing end seat is provided with the interior roller ball that mates with interior roller end.
Further, this roller bearing composite set is provided with several, and several cylindricality rollers are for being parallel to each other.
Further, the setting of mutually staggering of the roller bearing composite set on two sides.
Further, be provided with at this dull and stereotyped side and collude the act contiguous block, this colludes lifts contiguous block and can connect and collude the device of lifting work piece.
Compared with prior art, the present invention has the following advantages: the dull and stereotyped side at bending roller extension bar arranges the roller bearing composite set, so that the tubing after the Bending Processing takes out operation, change rolling friction into from existing sliding friction, greatly reduced frictional force between workpiece and the dull and stereotyped side, prolong the service life of bending roller extension bar, reduced simultaneously production cost, improved production efficiency.

The specific embodiment
Describe the present invention below in conjunction with accompanying drawing, the description of this part only is exemplary and explanatory, should any restriction not arranged to protection scope of the present invention.
A kind of bending roller extension bar 2 shown in Fig. 2,3 and 4 is slab construction, is provided with groove in this dull and stereotyped side, is provided with roller bearing composite set 4 in this groove.Two sides at flat board are equipped with roller bearing composite set 4, as shown in Figure 3.In addition in order conveniently to trigger work piece, be provided with to collude at the side of flat board and lift contiguous block 5, this colludes lifts contiguous block 5 and can connect and collude the device of lifting work piece, and as shown in Figure 2 one is colluded tool, can add another in its symmetric position again and collude and lift contiguous block 5; Bending roller extension bar 2 sides splicing with two the application consists of a larger area bending roller extension bar 2, and another colludes act contiguous block 5 and can be located on the corresponding side of another piece flat board.
This roller bearing composite set 4 is made of bearing and cylindricality roller 42, and this bearing is made of bearing end seat and C profile shaft bearing sleeve 40, and cylindricality roller 42 two ends are erected on the bearing end seat, and mid portion is embedded in the C profile shaft bearing sleeve 40; This cylindricality roller 42 is radially gone up part and is stretched out this C profile shaft bearing sleeve 40.Be embedded with several interior rollers 41 and interior roller in the inwall of this C profile shaft bearing sleeve 40 in conjunction with bar 43.
This bearing end seat is provided with the ball 44 with cylindricality roller 42 ends coupling.This bearing end seat is provided with the interior roller ball 45 with interior roller 41 ends coupling.
This roller bearing composite set 4 is provided with several, and several cylindricality rollers 42 are for being parallel to each other.The setting of mutually staggering of roller bearing composite set 4 on two sides, the roller bearing composite set 4 that arranges in the same side, spacing each other can be identical or different.
The roller bearing composite set 4 of projection is set in the dull and stereotyped side of bending roller extension bar 2 of the present invention, when workpiece is pulled out, the contact of the face in the conventional art or line contact friction is converted into rolling friction; This bending roller extension bar 2 is installed on the bender, can conveniently be applied in the stainless steel Bending Processing.
Because having reduced workpiece takes out difficulty from bender, reduced production cost; Simultaneously can directly workpiece be converted into excessive ring-type, namely the gap width after the processing when taking out from bender, can be omitted the follow-up operation of healing up less than the slab-thickness of bending roller extension bar 2, has shortened the process-cycle.
