Abstract

A kind of heavy and medium plate mill guide and guard backplate with mistake proofing bit function, including guide and guard backplate, described guide and guard backplate one end is equipped with guide and guard backplate claw, guide and guard backplate claw upper end is equipped with the guide and guard backplate hook for being used for being hooked in the small guide and guard backplate upper groove of working roll, prevents guide and guard backplate from outwards rocking the groove gone out on the small guide and guard backplate of working roll in impact process is rolled and misplacing.The utility model drop reduces the phenomenon that rolling mill guiding backplate dislocation faults frequent occurs, and solves the problems, such as rolling mill guiding backplate mistake groove, improves the yield of heavy and medium plate mill.

Description

A kind of heavy and medium plate mill guide and guard backplate with mistake proofing bit function

Technical field

It the utility model is related to a kind of heavy and medium plate mill guide and guard backplate with mistake proofing bit function.

Background technology

Guide and guard backplate before and after being improved after heavy and medium plate mill roll change, the claw of guide and guard backplate touch the small guide and guard backplate of working roll Connection step, during Rolling Production, guide and guard backplate is passively with working roll rise and fall, guide and guard backplate in operational process Wear liner, increases guide and guard backplate and the small guide and guard backplate joint gap of working roll, causes guide and guard backplate in the small guide and guard shield of working roll Connection area on plate is less and less, and area is smaller, and the frictional force that unit is born is bigger, aggravates the abrasion of claw.Work as contact surface Product it is small to a certain extent when, guide and guard backplate just easily misplaces, cause guide and guard backplate dislocation after by hydraulic cylinder it is automatic on It is raised to above working roll, due to increasing the guide range of guide and guard backplate and guide groove after rising, causes guide and guard backplate to be stuck in work Make on roller, can not decline, so as to cause working roll not replace, also easily occur to twine after steel plate lacks guide and guard in the operation of rolling Around work roll table equipment breakdown.

Utility model content

Its purpose of the utility model, which is that, provides a kind of heavy and medium plate mill guide and guard backplate with mistake proofing bit function, solves The working clearance increase of guide and guard backplate and working roll in itself, steel plate stamping, which is hit, easily causes the small guide and guard backplate of working roll to be protected with guide and guard The problem of plate support pawl departs from so as to not reach the working clearance needed for production, easy occurrence of equipment accident.

Adopt the technical scheme that to achieve the above object, a kind of heavy and medium plate mill guide and guard shield with mistake proofing bit function Plate, including guide and guard backplate, described guide and guard backplate one end are equipped with guide and guard backplate claw, and guide and guard backplate claw upper end, which is equipped with, to be used to be hooked in Guide and guard backplate hook in the small guide and guard backplate upper groove of working roll, prevents guide and guard backplate from outwards rocking punching in impact process is rolled The groove that goes out on the small guide and guard backplate of working roll and misplace.

Beneficial effect

The utility model has the following advantages compared with prior art.

The utility model has the advantages that solving the working clearance increase of guide and guard backplate and working roll in itself, steel plate stamping is hit Easily cause the small guide and guard backplate of working roll to depart from guide and guard backplate claw so as to not reach the working clearance needed for production, easily occur The problem of equipment breakdown, improve the yield of heavy and medium plate mill.

Brief description of the drawings

Below in conjunction with attached drawing, the utility model is described in further detail.

Fig. 1 is the structure diagram of the utility model；

Fig. 2 is utility model works schematic diagram.

Embodiment

The present apparatus includes guide and guard backplate 1, and as shown in Figure 1 and Figure 2, described 1 one end of guide and guard backplate is equipped with guide and guard backplate claw 2, 2 upper end of guide and guard backplate claw is equipped with the guide and guard backplate hook 3 for being used for being hooked in small 4 upper groove 5 of guide and guard backplate of working roll, prevents from leading Plate 1 is protected outwards to rock the groove 5 gone out on the small guide and guard backplate 4 of working roll in impact process is rolled and misplace.

The inner side of the guide and guard backplate hook 3 is incline structure.

Guide and guard backplate hook 3 is hooked in the groove 5 of the small guide and guard backplate 4 of working roll in the utility model, while is being led Protect the thickness of the outside increase 10mm of plate support pawl 2, the contact surface of increase guide and guard backplate claw 2 and the small guide and guard backplate 4 of working roll Product, the gap regardless of guide and guard backplate 1 Yu groove 5, guide and guard backplate hook 3 are hooked in the groove 5 of the small guide and guard backplate 4 of working roll In, prevent the phenomenon that guide and guard backplate 1 misplaces with the small guide and guard backplate 4 of working roll and occur.
