Detailed Description
The structure of the integral rough rolling pressure head provided by the embodiment is shown in figures 1-3.
Roughing is a process in which several layers of steel plates are stacked together and hot rolled into a sheet thinner than 2mm by a two-roll mill. When the pressure head 11 is roughly rolled, the pressure head 11 in the rough rolling process is an indispensable structure, and the pressure head 11 is utilized to press the steel plate under the action of large rolling force. As shown in figure 1, the structure of the existing pressure head 11 is that the center part of the pressure head 1111 is hollow, and a bottom plate 1212 below the pressure head 1111 is easily broken under the action of large rolling force due to uneven stress, so that a single-side roll gap is deviated, and the side bending of the strip steel is caused. Therefore, the indenter 11 of the prior art is not reliable enough.
In order to improve the problem that the stress of the pressure head 1111 is uneven in the prior art, the concept of the scheme is that the pressure head 11 is set to be a solid structure so as to improve the problem that the stress is uneven, and the scheme is as follows:
this integral rough rolling pressure head 11, including pressure head 11, pressure head 11 includes 11 roofs of pressure head, 11 middle levels of pressure head and 11 bottom plates of pressure head, and 11 roofs of pressure head, 11 middle levels of pressure head and the 11 bottom plates of pressure head connect gradually, can understand, and pressure head 11 comprises 11 roofs of pressure head, 11 middle levels of pressure head and 11 bottom plates of pressure head triplex, and 11 roofs of pressure head, 11 middle levels of pressure head and the 11 bottom plates of pressure head can be fixed connection in proper order, also can adopt the mode of bonding to connect.
Wherein, 11 middle levels of pressure head are solid to make pressure head 11 that 11 roof of pressure head, 11 middle levels of pressure head and 11 bottom plates of pressure head constitute be solid structure, it should be explained that 11 roof of pressure head and 11 bottom plates of pressure head also need be solid structure, under the effect that receives the external force, under big rolling force effect promptly, solid pressure head 11 atress is balanced, and 11 bottom plates of its pressure head are difficult for the fracture, in order to be used for improving 11 uneven problems of atress of pressure head, avoid causing the side bend of belted steel because of 11 bottom plate fracture of pressure head.
In the middle of practical application, because 11 bottom plates of pressure head receive pressure for a long time, 11 bottom plates of pressure head need bear outside frictional force, under the effect of big rolling force, 11 bottom plates of pressure head are impaired seriously easily often, consequently, this scheme sets up to dismantling between 11 bottom plates of pressure head and the 11 middle levels of pressure head and connects to be convenient for to 11 bottom plates of pressure head's change, improve 11 pressure head's life.
Exemplarily, corresponding threaded holes 3 are formed in the middle layer of the pressure head 11 and the bottom plate of the pressure head 11, and the bottom plate of the pressure head 11 and the middle layer of the pressure head 11 are provided with screws 4 in the threaded holes 3 in a penetrating manner. It will be appreciated that the threaded rods 4 are threaded into corresponding threaded holes 3 to effect a connection between the base of the ram 11 and the middle of the ram 11.
It should be noted that, in order to prevent the screw rod 4 from affecting the use of the pressure head 11, one end of the screw rod 4, which is far away from the top plate of the pressure head 11, is flush with one side of the bottom plate of the pressure head 11, which is far away from the top plate of the pressure head 11, so that the screw rod 4 can be prevented from protruding out of the bottom plate of the pressure head 11, and the placement of the bottom plate of the pressure head 11 is not affected.
Threaded hole 3 is equipped with two sets at least, and screw rod 4 is equipped with two at least, and for example, threaded hole 3 can be equipped with three, and screw rod 4 can be equipped with three. In this scheme, be equipped with two sets ofly at least with screw hole 3, screw rod 4 is equipped with two at least, can improve the stability of being connected between 11 bottom plates of pressure head and the 11 middle level of pressure head between the two.
The utility model provides a pair of integral rough rolling pressure head 11, pressure head 11 wherein comprises pressure head 11 roof, pressure head 11 middle level and pressure head 11 bottom plate triplex, and pressure head 11 roof, pressure head 11 middle level and pressure head 11 bottom plate connect gradually and constitute rough rolling pressure head 11, wherein, pressure head 11 middle level is solid. It can be understood that the rough rolling pressure head 11 formed integrally is an entity device, the hollow part is changed into an integral type, the problem of uneven stress of the pressure head 11 is solved, and the side bending of the strip steel caused by the fracture of the bottom plate of the pressure head 11 is avoided.
In addition to the above embodiments, the present invention may have other embodiments; all the technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope claimed by the present invention.
