Abstract
The utility model relates to the technical field of steel rolling, in particular to a supporting base. The supporting base comprises a supporting base main body and two supporting base bodies. The bottom ends of the two supporting base bodies are both of a plane structure, and a one fourth arc surface structure is respectively arranged on the two supporting base bodies. Two supporting base body installation grooves matched with the supporting base bodies are formed in the supporting base main body. The two supporting base bodies are fixed into the supporting base body installation grooves respectively. According to the supporting base, stress of the supporting base bodies and stress of the supporting base main body are even, and the service life of the supporting base bodies is prolonged.
Description
Technical field
The utility model relates to technical field of steel rolling, particularly a kind of supporting base.
Background technique
In hot-rolled coil is produced, the terminal check of roll bending plays an important role at aspects such as improving steel product quality, expansion kind, reduce costs and optimize steel rolling production process, becomes the restricted link in whole production process.The drop weight tearing shock test is a kind of important way of product made from steel check, and it has very high reference value aspect the pipe line steel examination and test of products, is the important evidence that the high-end variety steel such as pipe line steel is produced.While adopting ZCJ-40000 drop weight tearing impact testing machine to carry out dart drop impact test to the pipeline steel block hammer sample, at first the pipeline steel block hammer sample is placed on the bearing that drops hammer, then make the hammer body of 750kg freely fall from certain eminence, with the speed of 5-9m/s, sample is thrust.Between the bearing of cylindrical shape and support body, be that arc surface contacts, micro-elastic bending deflection can occur in the intermediate portion of the bearing of cylindrical shape under the impact that is subject to substantial load, and acutely clash into the bearing mounting groove of circular shape, make the bearing mounting groove diameter of circular shape become gradually large, cave in bottom surface, thereby caused bearing and bearing mounting groove not to fit tightly, make the bearing vacant state that mediates, be bearing with support body between contact and become 2 supportings, middle vacant state by original arc surface.Thereby during drop weight test, the Bearing Seat Force inequality, bearing intermediate portion stress is concentrated, and causes bearing frequently to rupture.Now, the arc groove bottom surface serious support body that caves in need to be changed and just the damage of sample bearing can be slowed down.
The model utility content
Technical problem to be solved in the utility model be to provide between a kind of bearing and support body stressed evenly, the supporting base of long service life.
For solving the problems of the technologies described above, the utility model provides a kind of supporting base, comprises support body and two bearings.The bottom of two described bearings is plane structure, and is respectively arranged with 1/4 arc surface structure on two described bearings.Be provided with two bearing mounting grooves that match with described bearing on described support body.Two described bearings are separately fixed in two described bearing mounting grooves.
Further, described support body comprises: base and two longerons.Two described longerons are over against setting, and two longerons are separately fixed on described base.The upper end of two described longerons is respectively arranged with a bearing mounting groove matched with described bearing.
Further, two described bearings are separately fixed in two described bearing mounting grooves by bolt.
The bearing device that the utility model provides, the bottom of two bearings is plane structure, be provided with two bearing mounting grooves that match with bearing on support body, between bearing and mounting groove on support body, for face, contact, increased the area of contact between the mounting groove on bearing and support body, make between bearing and support body stressed evenly, extended the working life of bearing.Bearing is bolted in the bearing mounting groove, has increased the stability between bearing and support body.
The accompanying drawing explanation
The support body structural representation that Fig. 1 provides for the utility model embodiment.
The seat structure schematic diagram that Fig. 2 provides for the utility model embodiment.
Embodiment
Referring to Fig. 1 and Fig. 2, a kind of bearing device that the utility model embodiment provides, comprise support body 1 and two bearings 3.Support body comprises: base 12 and two longerons 11.Two longerons 11 are over against setting, and two longerons 11 are separately fixed on base 12.The upper end of two longerons 11 is respectively arranged with a bearing mounting groove 2 matched with bearing 3.Referring to Fig. 1, the upper end of support body 1 is respectively arranged with two bearing mounting grooves 2.The bottom surface of two bearings 3 is plane structure, according to the GB requirement, is respectively arranged with 1/4 arc surface structure on two bearings 3, and the radius of arc surface is 14.3 ± 1.59mm.The shape of two bearing mounting grooves 2 is identical with the shape of two bearings 3 respectively, and two bearing mounting grooves 2 are matched with two bearings 3 respectively.In the utility model embodiment, two bearings 3 are separately fixed in two bearing mounting grooves 2 by bolt, and after two bearings 3 fix, 1/4 arc structure on two bearings 3 is over against setting.
The working principle of the bearing device that the utility model embodiment provides is as follows: at first that the pipeline steel block hammer sample is edge-on on bearing 3, and then make the hammer body of 750kg freely fall from certain eminence, with the speed of 5-9m/s, the pipe line steel sample is thrust.Hammer body is in the process of clashing into the pipe line steel sample, the pipe line steel sample applies downward power to bearing 3, owing to contacting for face between bearing 3 and bearing mounting groove 2, increased the area of contact between bearing 3 and bearing mounting groove 2, make between bearing 3 and support body 1 stressed evenly, extended the working life of bearing 3.In addition, bearing 3 is bolted in bearing mounting groove 2, has increased the stability between bearing 3 and support body 1, and is convenient for changing bearing 3.
The utility model embodiment has following beneficial effect:
1, the bottom of two bearings is plane structure, be provided with two bearing mounting grooves that match with bearing on support body, between bearing and mounting groove on support body, for face, contact, increased the area of contact between the mounting groove on bearing and support body, make between bearing and support body stressed evenly, extended the working life of bearing.
2, bearing is bolted in the bearing mounting groove, has increased the stability between bearing and support body, and is convenient for changing bearing.
3, simple in structure, cost is lower, be convenient in industrial a large amount of enforcement.
It should be noted last that, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to example, the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
