Abstract
The utility model discloses a pole mould is crowded to blade, comprises a punching head, the recipient, the extrusion is inserted, guide pin bushing and ejector pin, the recipient is opened along the axial has the through -hole, the through -hole includes by the lower supreme first locating hole that is linked together, the second locating hole, the hole, the radius of first locating hole is greater than the radius of second locating hole, the radius of second locating hole is greater than the radius of hole, the lower extreme that the extrusion was inserted is provided with fixes a position the boss with first locating hole matched with, upper end and second locating hole transition fit that the extrusion was inserted, and the up end that the extrusion was inserted top is leaned on on the transition face between second locating hole and hole. The utility model discloses an insert the lower extreme in the extrusion and set up the location boss, make its location accurate, stable, and the extrusion oral area design of inserting becomes and second locating hole, hole between transition face matched with terminal surface structure to the difficult wearing and tearing of oral area that feasible extrusion was inserted have improved the life that the extrusion was inserted greatly, have reduced the maintenance cost.
Description
Technical field
This utility model relates to a kind of mould, particularly relates to a kind of blade and squeezes bar mould.
Background technology
It is to carry out blade during Blade precision forging to squeeze a kind of mould of bar that blade squeezes bar mould, and it is typically made up of drift, recipient, extruding insert, guide pin bushing and push rod.As it is shown in figure 1, squeeze the fit structure schematic diagram of bar mould recipient and extruding insert for existing blade；The blade of this kind of structure squeezes bar mould, and the oral area of its extruding insert upper end is point limit, and it easily weares and teares, and service life is shorter, uses and is soon accomplished by changing, greatly reduces blade and squeeze the efficiency of bar, and increase maintenance cost, thus, is badly in need of solving.
Utility model content
The purpose of this utility model is for the problems referred to above, it is provided that a kind of blade squeezes bar mould, squeezes the extruding insert of bar mould and easily weares and teares solving existing blade, and service life is short, and maintenance cost is high, reduces the problem that blade squeezes bar efficiency.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of blade squeezes bar mould, including drift, recipient, extruding insert, guide pin bushing and push rod, described recipient has through hole vertically, described through hole includes the first hole, location being connected from the bottom to top, second hole, location, endoporus, the radius in described first hole, location is more than the radius in the second hole, location, the radius in described second hole, location is more than the radius of endoporus, the lower end of described extruding insert is provided with the positioning boss matched with the first hole, location, the upper end of extruding insert and the second hole, location interference fits, and the upper surface of extruding insert acts against on the transition face between the second hole, location and endoporus.
As a kind of preferred version of the present utility model, described drift is locked by upper latch segment.
As a kind of preferred version of the present utility model, described recipient is locked by lower latch segment.
Coordinate as a kind of preferred version of the present utility model, the positioning boss of described extruding insert and the first location interporal lacuna.
The beneficial effects of the utility model are, described a kind of blade squeezes bar mould by arranging positioning boss in extruding insert lower end, make its registration, stablize, and the oral area of extruding insert is designed to position, with second, the end face structure that the transition face between hole, endoporus matches, so that the oral area of extruding insert is the most easy to wear, substantially increases the service life of extruding insert, reduce maintenance cost, decrease maintenance times, improve blade and squeeze bar efficiency.

Detailed description of the invention
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by detailed description of the invention.It is understood that embodiment described herein is used only for explaining this utility model, rather than to restriction of the present utility model.
Refer to shown in Fig. 2 and Fig. 3, Fig. 2 is the structural representation that a kind of blade of this utility model squeezes bar mould；Fig. 3 is the fit structure schematic diagram of this utility model recipient and extruding insert.
nullIn the present embodiment，A kind of blade squeezes bar mould，Including drift 1、Recipient 3、Extruding insert 4、Guide pin bushing 6 and push rod 7，Described drift 1 is locked by upper latch segment 2，Described recipient 3 is locked by lower latch segment 5，Recipient 3 has through hole vertically，Described through hole includes the first hole, location being connected from the bottom to top、Second hole, location、Endoporus 31，The radius in described first hole, location is more than the radius in the second hole, location，The radius in described second hole, location is more than the radius of endoporus 31，The lower end of described extruding insert 4 is provided with the positioning boss 41 matched with the first hole, location，Described positioning boss 41 coordinates with the first location interporal lacuna，The upper end of described extruding insert 4 and the second hole, location interference fits，And the upper surface of extruding insert 4 acts against on the transition face 32 between the second hole, location and endoporus 31.
Above-mentioned blade squeezes bar mould, and oral area of its extruding insert 4 upper end is designed to end face structure, matches with the second location transition face 32 between hole, endoporus 31, not only increases positioning precision, and can extend its service life, simple in construction, is easily achieved.
Above example simply elaborates ultimate principle of the present utility model and characteristic; this utility model is not limited by above-described embodiment; on the premise of without departing from this utility model spirit and scope; this utility model also has various change and change, in the range of these changes and change both fall within claimed this utility model.This utility model claims scope and is defined by appending claims and equivalent thereof.
