Abstract
The utility model provides a rod piece pressing and bending die with a threaded female die loose piece. The rod piece pressing and bending die with the threaded female die loose piece comprises an upper die body, a lower die body and the female die loose piece. Inserts are inlaid in the upper die body and the lower die body, and a cavity used for containing the female die loose piece is formed in the side, the same with the lower die body, of the upper die body. The rod piece pressing and bending die with the threaded female die loose piece has the advantages that the problem that the thread part in a rod piece with threads is close to a bending point, so that forming is inconvenient is solved, meanwhile, the problem that an existing die can damage threads due to pressing is solved, stress of the threads close to the bending point is made to be even, and product requirements can be met. In addition, the rod piece pressing and bending die with the threaded female die loose piece is simple in structure, convenient to maintain, low in processing cost and high in production efficiency.
Description
Technical field
The utility model belongs to the molded processing technique field of metal cold, especially relates to a kind of rod member bending die of threaded die loose piece.
Background technology
Erecting device is the product of railway for the track switch conversion, and bar class connector product category wherein is various, and such workpiece blank is forging, needs bent into shape after machined threads.Former rod member threaded portion is distant apart from bending part, and mould adopts the curved bent into shape of upper and lower mould two.Along with the railway speed increase requirement, the threaded portion of part connecting rod is too near bending part, screw thread enters among die because rod member is different from the threaded portion diameter, die moulding part of the force as by member design threaded portion do not reach can't moulding, as be damaged by threaded portion design stressed screw thread that makes of screw thread in the press-bending process, can not meet the product design requirement.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of rod member bending die of simple in structure, easy to operate threaded die loose piece.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of rod member bending die of threaded die loose piece, comprise upper die and lower die and threaded die loose piece, on described patrix and described counterdie, is inlaid with and inserts, and the same side of described patrix and described counterdie is provided with for placing the die cavity of described die loose piece.
Further, described patrix is fixedly connected with lower shoe with upper plate respectively with described counterdie.
Further, described die loose piece is semicircle.
Further, be provided with the guide pillar for location between described patrix and described counterdie.
Further, on described counterdie, be equipped with for determining the positioner of workpiece installation initial position, described positioner comprises location-plate and is bolted on the locating piece on described location-plate.
Further, described patrix is fixed on described upper plate with straight pin and soket head cap screw, and described counterdie is fixed on described lower shoe with straight pin and soket head cap screw.
Further, described positioner is bolted on described counterdie.
Advantage and the good effect that the utlity model has are: adopt above technical scheme, solve threaded portion in threaded rod member and approached the problem that inconvenient moulding is put in bending, solved the problem that original mould weighs screw thread wounded simultaneously, make to approach the screw thread uniform stressed of bending point, can reach product requirement.In addition, the utility model is simple in structure, easy to maintenance, processing cost is low, production efficiency is high.

The specific embodiment
As shown in Figure 1; the utility model relates to a kind of rod member bending die of threaded die loose piece; comprise patrix 1, counterdie 2 and threaded die loose piece 7; be inlaid with and insert 5 on described patrix 1 and described counterdie 2, the same side of described patrix 1 and described counterdie 2 is provided with the die cavity 6 for placing described die loose piece 7.
Further, described patrix 1 is fixedly connected with lower shoe 4 with upper plate 3 respectively with described counterdie 2.
Further, described die loose piece 7 is semicircular die loose piece.
Further, be provided with the guide pillar 8 for location between described patrix 1 and described counterdie 2.
Further, on described counterdie 2, be equipped with for determining the positioner of workpiece installation initial position, described positioner comprises location-plate 9 and is bolted on the locating piece 10 on described location-plate.
Further, described patrix 1 use straight pin and soket head cap screw are fixed on described upper plate 3, and described counterdie 2 use straight pins and soket head cap screw are fixed on described lower shoe 4.
Further, described positioner is bolted on described counterdie 2.
The course of work of this example: at the press-bending initial state, rod member is placed on to die cavity 6 places of counterdie 2; one end is adjacent to locating piece 10 and determines the rod member placement location; the die loose piece 7 of threaded semicircle is positioned over rod member screw thread place, and reserves axial internal clearance at die loose piece 7 places.In the press-bending process, the die loose piece 7 of two threaded semicircles is closely connected with rod member screw thread place and swing and move axially with rod member all the time, effective protection threaded portion in forming process.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
