Technical field
The utility model relates to large-sized multiple-skew roller pipe, bar straightener technology, relates in particular to a kind of multi-cross roll straightening machine locking device.
Background technology
Along with deepening continuously of reforming and opening up to the outside world, particularly after the China joined WTO, economical to the globalization development, large-scale pipe bar equipment for straightening is competed fierceness more on the market at home and abroad.All trades and professions make the scale day by day of equipment for straightening scale, maximization, intellectuality to the wilderness demand of large-scale pipe bar aligning product, also are the inexorable trends of development in future.
At present, steel industry is extensively employed new technology and new technology, solves because the technical barrier that maximizes and produced.The multi-cross roll straightening machine of traditional small dimension is to be one with locking cylinder and balancing cylinder, be installed in the upper spider, realize two kinds of functions by an oil cylinder, hydraulic control is complicated and unreliable, and exists the piston stroke of locking cylinder can be according to the size design of aligning specification limit, and often piston stroke is very long, processing time consuming is taken material, complex process, difficulty of processing is big, the very complicated shortcoming of locking link.
Summary of the invention
For overcoming the deficiencies in the prior art, the utility model provides a kind of multi-cross roll straightening machine locking device, and it is big to have a cylinder diameter, and stroke is short, and is simple in structure, dependable performance, advantage such as hydraulic control is reliable.Be fit to the locking of big specification tube bar straightening machine top roll, not only ease of assembly but also the comprehensive sealing effect and service life of having improved the seal of locking cylinder.
For realizing aforesaid goal of the invention, the utility model adopts technical scheme as described below:
Described a kind of multi-cross roll straightening machine locking device, comprise: cylinder body, slide, rotating disk, threaded and dish spring recover mechanism, the cylinder body of described locking cylinder is arranged in the slide, fix by bolt and slide, the cylinder body top is provided with pressing plate, the cylinder body inboard has the many places seal groove, places the combination seal of some quantity; Piston is positioned at cylinder body, and described threaded passes piston, cylinder body, slide and rotating disk, is fixed together by nut I and nut II; Be provided with the dish spring in the described piston and recover mechanism.
Described a kind of multi-cross roll straightening machine locking device, the piston inboard has the many places seal groove at the different-diameter place, places the sealing ring of some; Be provided with the dish spring hole of some quantity in the piston.
Described a kind of multi-cross roll straightening machine locking device, dish spring recover mechanism and are made of dish spring, bearing pin in the piston dish spring hole, and described dish spring is connected with cylinder body with piston by bearing pin.
Described a kind of multi-cross roll straightening machine locking device, the inside and outside footpath of the internal diameter of the cylinder body of described locking cylinder and piston has sealed groove, is embedded seal.
Owing to adopt aforesaid technical scheme, the utlity model has following beneficial effect:
A kind of multi-cross roll straightening machine locking device belongs to the locking device that multi-cross roll straightening machine tightens up slide and rotating disk.It is big to have cylinder diameter, and stroke is short, and is simple in structure, dependable performance, and advantage such as hydraulic control is reliable is fit to the locking of big specification tube bar straightening machine top roll.Because this locking device adopts multi-level Seal Design, has both made things convenient for assembling, has eliminated mismachining tolerance, the comprehensive sealing effect and the service life of having improved the seal of locking cylinder again simultaneously.

Among the figure: the 1-slide; The 2-cylinder body; The 3-piston; The 4-threaded; 5-nut I; The 6-pressing plate; The 7-combination seal; 8-dish spring; The 9-bearing pin; The 10-sealing ring; The 11-bolt; The 12-rotating disk; 13-nut II;
The specific embodiment
As shown in Figure 1: a kind of multi-cross roll straightening machine locking device belongs to the locking device that multi-cross roll straightening machine tightens up slide and rotating disk.It mainly comprises assemblies such as cylinder body 2, piston 3, threaded 4, nut I5, pressing plate 6, combination seal 7, dish spring 8, bearing pin 9, sealing ring 10, bolt 11, nut II13.Cylinder body 2 designs of described locking cylinder are placed in the slide 1, and are fixing with slide 1 with bolt 11, and its top design has pressing plate 6, helps combination seal 7 operate as normal.Cylinder body 2 inboards have the many places seal groove, place the combination seal 7 of some.Piston 3 is positioned at cylinder body, by threaded 4, nut I5 and nut II13 cylinder body 2, piston 3, slide 1, rotating disk 12 is fixed together.Piston 3 inboards have the many places seal groove at the different-diameter place, place the sealing ring 10 of some.In piston 3, be provided with dish spring 8 and recover mechanism.Be processed with the hole of some in the piston 3, dish spring 8 is placed on the inside, dish spring 8, piston 3 and cylinder body 2 are coupled together with bearing pin 9.The inside and outside footpath of the internal diameter of described cylinder body 2 and piston 3 has sealed groove, is embedded seal.This locking device adopts multi-level Seal Design, has both made things convenient for assembling, has eliminated mismachining tolerance, the comprehensive sealing effect and the service life of having improved the seal of locking cylinder again simultaneously.
During work, behind the hydraulic oil that pours certain pressure in the oil pocket, piston 3 rises, and drives nut I5 and threaded 4 risings, and nut II13 drives rotating disk 12 and rises, and rotating disk 12 and slide 1 are compressed, and plays the purpose of locking.
When needs unclamp, system decompression, piston 3 returns, and nut I5, threaded 4, nut II13 and rotating disk 12 descend, and obtain the purpose that slide 1 and rotating disk 12 unclamp.Simultaneously, can design the stroke and the pressure of dish spring 8, make the pretightning force of dish spring 8 overcome the frictional force and the oil pressure of sealing ring effectively, better reach the stroke that returns setting according to operating position.
This new type of locking device, the advantage such as it is big to have a cylinder diameter, and stroke is short, and locking is firmly simple, and mechanical dish spring returns, and can effectively overcome frictional force and the oil pressure of sealing ring, and backstroke is accurate, and hydraulic control is reliable. Be fit to the locking of big specification pipe, bar straightener top roll rotating disk and slide, overcome the flywheel moment that produces in the process of aligning, the roller corner that is fixed makes roller and pipe, bar that good contact wire can be arranged.
