Convex spherical pad through graphite cast iron can improve bulk strength and wear resistance to prolong its life, reduce use cost, simultaneously, lubricate and cool off the convex spherical pad through strip -type oil groove, further improve life.
Description
Technical field
The utility model belongs to metal shaping equipment technical field, is specifically related to a kind of connection joint of rolling mill screwdown device.
Background technology
The connection joint of rolling mill screwdown device is the flexible vitals transmitting power, and its quality overall performance to screwdown gear transmitting roll-force plays vital effect.But the convex spherical pad in existing connection joint adopts copper product to make, its material is softer, easy wearing and tearing, the work absolute altitude of screw mandrel concave surface pad and convex spherical pad is caused to reduce, concave surface pad outer rim is interfered with thrust block seat pedestal and is contacted, and formation is spinned, time serious, concave surface pad outer rim also can embed in thrust block seat pedestal, and convex spherical pad cannot successfully be departed from screw mandrel concave surface pad.Meanwhile, the convex spherical pad changed can not reuse due to wearing and tearing, can only work as copper scrap and reclaim, and cause spare part expense to remain high, use cost is high.
For the problems referred to above, be necessary to improve the structure in existing connection joint, improve convex spherical pad bulk strength and anti-wear performance, screw mandrel concave surface pad and thrust block seat pedestal are not interfered, thus effectively reduce cost of equipment, stop pressure head and to spin accident, guarantee production direct motion.
Utility model content
In view of this, the purpose of this utility model is the connection joint providing a kind of rolling mill screwdown device, causes so that the convex spherical pad solving prior art existence is easy to wear the problem that absolute altitude change causes pressure head to spin and use cost is high.
The purpose of this utility model is achieved through the following technical solutions:
The connection joint of rolling mill screwdown device, comprise thrust block seat, be fixed on convex spherical pad in thrust block seat bore and the concave spherical surface pad bonded to each other with convex spherical pad, equal pressure pad, bearing structure and supporting construction is disposed with below described convex spherical pad, be connected and fixed with screw mandrel above described concave spherical surface pad, described convex spherical pad is that graphite cast iron material integrally casting is shaping, the convex surface of described convex spherical pad is provided with multiple by the outward extending bar shaped oil groove in convex surface center, the oil supplying hole that described bar shaped oil groove is arranged with through convex spherical pad is communicated with.
Further, the width of described bar shaped oil groove strengthens outward gradually along the convex surface center of convex spherical pad.
Further, between described concave spherical surface pad and the bore of thrust block seat for gap is arranged.
Further, described gap is one side gap 0.5-3mm.
The beneficial effects of the utility model are:
The utility model is by the convex spherical pad of graphite cast iron material, its bulk strength and anti-wear performance can be improved, thus extend its service life, reduce use cost, meanwhile, by bar shaped oil groove, oilhole, lubrication and cooling is carried out to convex spherical pad, improve friction condition, further raising service life, reduce the interference of concave surface pad and thrust block seat pedestal, thus effectively reduce cost of equipment, stop the accident of spinning.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on will be apparent to those skilled in the art to investigating hereafter, or can be instructed from practice of the present utility model.Target of the present utility model and other advantages can be realized by description below and obtain.
Accompanying drawing explanation
In order to make the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model is described in further detail, wherein:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of the utility model convex spherical pad.
Detailed description of the invention
Hereinafter with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail.Should be appreciated that preferred embodiment only in order to the utility model is described, instead of in order to limit protection domain of the present utility model.
As shown in the figure, the connection joint of the rolling mill screwdown device of the present embodiment, comprise thrust block seat 1, be fixed on the convex spherical pad 2 in thrust block seat 1 bore and the concave spherical surface pad 3 bonded to each other with convex spherical pad 2, equal pressure pad 4 is disposed with below described convex spherical pad 2, bearing structure and supporting construction, be connected and fixed with screw mandrel 5 above described concave spherical surface pad 3, described convex spherical pad 2 is that graphite cast iron material integrally casting is shaping, the convex surface of described convex spherical pad 2 is provided with multiple by the outward extending bar shaped oil groove 7 in convex surface center, the oil supplying hole 6 that described bar shaped oil groove 7 is arranged with through convex spherical pad is communicated with, this oil supplying hole 6 is communicated with the extraneous circulatory system, lubricating oil is made to continue through bar shaped oil groove 5, continue the working face lubrication and cooling to convex spherical pad 2, improve friction condition, further raising service life, reduce the interference of concave spherical surface pad 3 and thrust block seat 1.
The present embodiment is by the convex spherical pad of graphite cast iron material, its bulk strength and anti-wear performance can be improved, thus extend its service life, reduce use cost, simultaneously, by bar shaped oil groove, oilhole, lubrication and cooling is carried out to convex spherical pad, improve friction condition, improve service life further, reduce the interference of concave surface pad and thrust block seat, thus effectively reduce cost of equipment, stop the generation of the accident of spinning, production is carried out smoothly.
In the present embodiment, the width of described bar shaped oil groove 5 strengthens outward gradually along the convex surface center of convex spherical pad 2, can increase with the disc diameter passed and increase, thus increase Cooling and Lubricator area, improve Cooling and Lubricator effect.
In the present embodiment, for gap is arranged between described concave spherical surface pad 3 and the bore of thrust block seat 1, after convex spherical pad 2 weares and teares, even if concave spherical surface pad 3 declines enter the bore of thrust block seat 1, both also can not produce interference, further increase the security of operation, preferred gap is one side gap 0.5-3mm or double-faced clearance 1-6mm, and this interference occurs hardly.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of the technical program, it all should be encompassed in the middle of right of the present utility model.
