Description

A kind of rail head connecting type joint clamping plate of AT rail

Technical field

This utility model is related to railway equipment manufacture field, specifically, is related to a kind of technology of AT rail joint clamping plates Field.

Background technology

From the beginning of 2005, both at home and abroad each track switch manufacturer expands automatization's rail in AT rail heel end forging and stamping operation Part feeding is transformed, and system is clamped, moves up and down, moving left and right automatically to rail member and 180 ° of scopes are rotated, and realizes rail member The actions such as automatization comes out of the stove, traversing positioning, longitudinal register, withdrawing pattern, reset, blanking.But the system mechanics structural principle is limited, respectively Track switch producer design function is only capable of meeting the production operation of more than 6.2 meters rail members.

At present the common cut lengths of AT rail former materials is 25 meters, and the type rail member is processed elongated for making point tongue And heart rail, wherein tongue product accounting up to more than 90%, because tongue forging and stamping automatization rail member feed system is only capable of meeting 6.2 meters The production operation of above length, and in the point tongue of all kinds of patterns, AT steel-rail rail-road switch rail member accounting of the length less than 6.2 meters More than 45%.When blanking former material residue rail member length is less than the length, rail member can only make scrap iron process, cause each track switch factory steel Rail former material utilization rate declines, and track switch production cost increases, and firms profitability is limited.

Rail head of rail connecting type joint clamping plate is to realize rail member using clamping plate and lateral holding screw at rail head of rail position Connection, it is not used in rail track, is according to each track switch producer heel end die mould mechanized production system rail member method of clamping And the Novel joint connected mode of stand-alone development, it is therefore intended that after rail member is lengthened, while ensureing the rail of heel end die mould feed system Bottom holding action is unaffected, so as to complete the heel end forging and stamping production of product rail member of the length less than 6.2 meters.

Utility model content

The technical problems to be solved in the utility model：

Product rail member of the length less than 6.2 meters is allow clamped by heel end die mould mechanized production system, so that long Product rail member of the degree less than 6.2 meters can be processed using heel end die mould mechanized production system.

The technical solution of the utility model：

A kind of rail head connecting type joint clamping plate of AT rail, the joint bar length direction be divided into product rail member section and Technique matches somebody with somebody rail section two parts；The joint bar is divided into the long limb side of joint bar and joint bar phocomelic side two in width Point, wherein connecting the benchmark that is installed by rail member of joint bar phocomelic side.

Product rail member segment length's limb side in rail head, web of the rail position preset clearance 2mm, and laterally, rail top surface vertically to Arrange a number of trip bolt；The technique presses the processing of rail profile pattern with rail section in the web of the rail, rail head scope, does not reserve Gap.

Technique is fastenedly connected with rail section by the technique of joint bar with rail with joint bar.

The gap that product rail member exists by joint bar with product rail member, product rail member is inserted directly into joint bar；Produce After product rail member is contacted with technique with rail, by lateral holding screw by product rail member and joint bar clamping fastener.

The long limb side of joint bar of the joint bar and joint bar phocomelic side two parts are separate and separable , by joint bar top arrangement joint bar attachment screw, realize the long limb side of joint bar and joint bar phocomelic side It is fixedly connected.

Joint bar lower surface is with rail flange of rail identity distance from more than coverage during rail clamp flange of rail clipping operation；Joint Clamp maximum effect region when clamping plate combination outline rotates less than dolly clamping rail.

Beneficial effect：

The technical solution of the utility model has rational in infrastructure, simple and practical, highly versatile, convenient for installation and maintenance to wait special Point, it is adaptable to steel rail track switch fine-forging technology production line, can be widely applied to rail part heel end forging field.

Using the technical solution of the utility model, solve below original 6.2 meters of AT rail length that clout can only be by waste material The caving-in bash of process, improves AT rail former material utilization rates, reduce further enterprise's track switch production cost, realizes drop originally Potentiation.

Meanwhile, the rail member scope of application of existing steel rail track switch fine-forging technology production line has been expanded, meet less than 6.2 meters rail members Rail member automatization feeding action request, make enterprise's heel end die mould mechanized production system possess processing less than 6.2 meters heel ends forging The technical conditions and production capacity of pressure rail member.
