Abstract
The utility model discloses a U-shaped rib compressing cover die, which is used for compressing U-shaped ribs. The U-shaped rib compressing cover die comprises a bending machine cutting head (4), wherein a circular arc-shaped die is sleeved at the cutting edge of the bending machine cutting head; and the circular arc of the outer side of the circular arc-shaped die is equal to the bending inner diameter of a U-shaped rib. According to the technical scheme of the U-shaped rib compressing cover die, the design requirement of the compressing accuracy of the radius of the inner side of the U-shaped rib can be met completely, and the U-shaped rib compressing cover die is simple in structure, low in machining cost, light in weight and convenient to assemble and disassemble; and the U-shaped rib compressing cover die can compress the U-shaped ribs with different radii by replacing the thicknesses of lagging plates on inner and outer sides, so that the cost of manufacturing the die is reduced greatly, and the compressing efficiency of a compression machine is improved.
Description
Technical field
The utility model relates to a kind of U rib compacting cover die of making the U type rib of railway steel bridge orthotropic plate and highway steel case back base plate.
Background technology
Rail iron trusses cross bridge floor board and highway bridge steel case beam are Longspan Bridge common structural forms, use more and more widely.Need welding U type ribbed stiffener to increase the rigidity of floorings or roof and floor on steel truss girder bridge panel and steel case back plate or the base plate; More and more universal along with domestic and international steel bridge beam, the also corresponding diversification of the U rib form on the steel bridge deck, U rib radius also changes more thereupon; U rib compacting tool set can't be satisfied the demand at all; If to every kind of special customized a kind of mould of U rib compacting, its cycle is long, cost is high.The duration of present engineering is more and more anxious, and customized mould can't satisfy the construction period of this project at all.The compacting cover die that design is fit to different U rib radiuses is just becoming current exigence.
Summary of the invention
Goal of the invention: the purpose of the utility model is the deficiency to prior art; Provide a kind of, can satisfy the precision of the inner radius designing requirement of compacting U rib fully, and simple in structure, processing cost is low, mold weight is light, installation and removal easily the U rib suppress cover die; This U rib compacting cover die can be through changing the thickness of medial and lateral cage plate; The U rib of compacting different radii type has greatly reduced the making die cost, has improved forcing press compacting efficient.
Technical scheme: in order to realize the foregoing invention purpose, the technical scheme that the utility model adopted is:
A kind of U rib compacting cover die comprises the bender cutter head, and the place is socketed with circular-arc mould at described bender cutter edge, and the bending internal diameter of the outer arc of described circular-arc mould and U rib is suitable.
Described circular-arc mould comprises inboard cage plate and outside cage plate; Described outside cage plate is coated on the inboard cage plate outside; Between inboard registering and bender cutter head, be provided with the backing plate that is used to increase circular-arc mould and bender cutter head adhesion, the external arc of described outside cage plate is suitable with the bending internal diameter of U rib.
Described backing plate and bender cutter head are welded to connect.
Be intermittent weld between described backing plate and the bender cutter head, every separated 300mm spot welding once.
Along the inboard cage plate width dimensions of the edge direction of bending cutter head is 150mm, and outside cage plate width dimensions is 80mm.
Carry out seamless assembly unit during the assembling of U rib compacting cover die and get final product, the medial and lateral cage plate all adopts steel plate compression moulding, and the medial and lateral cage plate is processed according to bender cutter head angle of inclination and cutting edge camber line; Backing plate is processed by steel plate according to the closed intensity of medial and lateral cage plate and cutter, and inboard cage plate is processed according to width dimensions 150mm, and outside cage plate is processed according to width dimensions 80mm; After machining; The medial and lateral cage plate is socketed on the bender cutter head, its adaptation is replenished, it is fully combined with the bender cutter head with backing plate; Through composition backing the medial and lateral cage plate is fixed on the bender cutter head; Notice during electric welding that whenever at a distance from 300mm spot welding once, 2 meters long spot welding quantity are no more than 6 places in order to be interrupted electric welding.
Beneficial effect: the utility model compared with prior art, its beneficial effect is:
1, the principle of circular-arc mould of the utility model and the socket of bender cutter head, circular-arc mould is divided into inboard cage plate and outside cage plate, has solved circular-arc Mould Machining difficulty, the difficult problem that process equipment is rare; Reduce difficulty of processing, improved die production efficient;
2, after the utility model adopts circular-arc mould and the assembling of bender cutter head; Embedding is used to increase the backing plate of circular-arc mould and bender cutter head adhesion; Backing plate and bender cutter head are welded to connect, and have solved the big problem of circular-arc mould abnormity curve installation difficulty;
3, the medial and lateral cage plate is processed respectively, has reduced the difficult point of integral plate machined moulding, has characteristics simple in structure, that processing cost is low, the production cycle is fast;
4, the medial and lateral cage plate has the advantages that all by the bullodozer roll-forming processing cost is low, the production cycle is fast, has also simplified the manufacture process of mould simultaneously;
5, be intermittent weld between backing plate and the bender cutter head, can change the medial and lateral cage plate according to the radius bend of different U ribs, it is convenient to change, and has greatly reduced the making die cost, has improved forcing press compacting efficient.
