Abstract

The utility model relates to a die for accurately extruding an inner hole on a hydraulic machine tool. The die includes an upper shoe and a lower shoe, a guide pole and a guide sleeve are arranged between the upper shoe and the lower shoe, the die is characterized in that an extruding bar is arranged on the lower end of the upper shoe, and a concave die is arranged on the lower shoe at a corresponding position. The extruding bar includes an extruding rod, the lower side of the extruding rod is provided with extruding loops and spacers sleeved mutually in interval, and the external diameters of the extruding loops are decreased in sequence from top to bottom. The beneficial effects of the utility model are that it is possible to fulfill multiple extrusions by one stroke, the processing hole has a high precision, the size is accurate, and the quality is table; it is possible to meet the processing requirement of different holes by replacing the extruding loops; operation is simple, production efficiency is high, and the extruding bar is replaced easily.

Description

A kind of precision is squeezed punch die
Technical field
The utility model relates to a kind of accurate mould that squeezes the hole of endoporus that is used for realizing on the hydraulic machine.
Background technology
At present, the accurate endoporus of stamping parts is used wider, but the processing technology more complicated, inefficiency.A common flange hole is done a few cover frocks possibly and is squeezed the hole successively, and wherein one process dimension just is not inconsistent may influence subsequent production, or even the change of frock, so not only increased processing cost, and production efficiency is low.Though adopt Cutter Body Processing with Machining Center can guarantee the precision in hole but the processing cost height.
Summary of the invention
Technical problem to be solved in the utility model is to provide the precision that a kind of crudy is good, production efficiency is high, easy to use to squeeze punch die at the deficiency of above-mentioned prior art existence.
The technical scheme that the utility model adopted is: include upper bolster and die shoe, be provided with guide pillars and bushes between upper bolster and the die shoe, it is characterized in that the extruding rod is installed in the lower end of upper bolster, correspondence is installed die on the die shoe.
Press such scheme, described extruding rod comprises pressure ram, is installed on the extrusion ring and the spacer ring of socket at interval below pressure ram, and the external diameter of extrusion ring successively decreases from top to bottom successively, and the lower end configuration lock jack panel of pressure ram is used for the locking of extrusion ring; Described extrusion ring is provided with 3~5.
Press such scheme, described extruding rod connects firmly with upper bolster mutually by upper fixed seat and upper padding plate; Described die connects firmly by lower fixed seat and lower bolster and die shoe.
Press such scheme, in the middle of the described die through hole is set, be installed on the edge cover in the through hole, edge cover internal diameter is identical with the extrusion ring maximum outside diameter.
Press such scheme, fixedly unloading block is housed, be used for the spacing and backstop of work piece in lower fixed seat one side.
The utility model beneficial effect is: 1, finish the multiple tracks extruding by one stroke, and the endoporus precision height of processing, size guarantees easily, steady quality; 2, by changing the extrusion ring of various outer diameter, can satisfy the process requirements in different size aperture; 3, simple to operate, the production efficiency height, the replacing of extruding rod is easy to maintenance.
Description of drawings
Fig. 1 is the sectional structure chart of an embodiment of the utility model.
Fig. 2 is the partial sectional view of extruding rod among embodiment of the utility model.
The specific embodiment
Below in conjunction with the specific embodiment and accompanying drawing the utility model is further described.
Include upper bolster 17 and die shoe 1, be provided with guide pillar 11 and guide pin bushing 12 between upper bolster and the die shoe, guide pillars and bushes disposes mutually and is connected with upper bolster with die shoe respectively, the extruding rod is installed by upper fixed seat 15 and upper padding plate 16 in lower end at upper bolster, described extruding rod comprises pressure ram 14, pressure ram is the axle shape, below pressure ram, be installed on 3 extrusion rings 13 and 3 spacer rings 10 of socket at interval, the external diameter of extrusion ring successively decreases from top to bottom successively, the external diameter lapse rate (reduced diameter rate) of every grade of extruding circle is 0.3~0.5%, the extrusion ring external diameter of going up most is identical with the aperture of machining hole, the lower end configuration packing ring 8 and the locking nut 7 of pressure ram, be used for the locking of extrusion ring, can further improve the abrasion resistance properties and the crowded hole quality of extruding circle in the periphery titanizing of extrusion ring; Corresponding pressure ram is installed die 4 on the die shoe, and die connects firmly with die shoe by lower fixed seat 3 and lower bolster 2, in the middle of the described die through hole is set, and is installed on edge cover 5 in the through hole, and edge cover internal diameter is identical with the extrusion ring maximum outside diameter.In bottom plate one side fixedly unloading block 6 is housed, fixedly the upper end of unloading block is provided with stop block, is used for the spacing and backstop of work piece 9.
The utility model can realize that a plurality of holes process simultaneously, can enhance productivity greatly installing many extruding rods and die on the die holder up and down according to actual conditions.
