Abstract
A punch comprises a body, an alloy ring is mounted on the outer periphery of the front end of the body, and the outer end face of the alloy ring and the front end face of the body are positioned in a same plane. The punch is heat-resistant and wear-resistant, fine in impact toughness, and reasonable in structural design, and the front end of an ejector pin is made of alloy materials and other parts of the ejector pin are made of common materials, so that cost is reduced and the punch can be widely used beneficially.
Description
Technical field
The utility model relates to a kind of mould, relates in particular to a kind of drift.
Background technology
At present, known hot forged mould structure is directly made by a kind of mold materials, and manufacturing process roughly is mould steel material base, roughing, heat treatment, surface treatments such as mill processing and nitrogenize.Because drift is work under the environment of HTHP power, therefore to itself material requirements ten minutes harshness, its overall structure needs heat-resistant antifriction, and the shaping impulsive force is big, also needs good impact flexibility.For the quality and the service life of improving drift, the integral material of drift needs nickel, tungsten, and precious metals such as molybdenum constitute, and its price is very expensive.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, provides a kind of front end to be inlaid with the drift of alloy hoop.
The utility model solves the technical scheme that its technical problem adopts: this drift, comprise main body, and the periphery of body front end is equipped with alloy hoop, and the outer face of this alloy hoop and the end face of body front end are positioned at same plane.The front end of this structure and hot forging contact portion are inlaid with alloy hoop, and this alloy hoop adopts interference fit to be pressed in the drift, and the mode of being pressed into can be a hot jacket, and cold cover or mechanical method of press-fitting make drift both take into account heat-resistant antifriction, have good impact flexibility again simultaneously.
The front end of main body is provided with cooling holes, and this cooling holes one end runs through from the front end face of main body, and the other end runs through from the side of main body.This cooling holes is used to carry cooling fluid, and cooling fluid flows to from the side of ejector pin, flows out from front end, and cooling-down effect is better.
The effect that the utility model is useful is: the utility model had both been taken into account heat-resistant antifriction, had good impact flexibility and reasonable in design again simultaneously; The fore-end of ejector pin adopts alloy material; Other parts adopt general material, have reduced cost, help being widely used.
Description of drawings
Fig. 1 is the whole cutaway view of the utility model.
Description of reference numerals: main body 1, alloy hoop 2, cooling holes 3.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
With reference to accompanying drawing: this drift, comprise main body 1, the periphery of main body 1 front end is equipped with alloy hoop 2, and the end face of the outer face of this alloy hoop 2 and main body 1 front end is positioned at same plane.The front end of this structure and hot forging contact portion are inlaid with alloy hoop 2, and this alloy hoop 2 adopts interference fit to be pressed in the drift, and the mode of being pressed into can be a hot jacket, and cold cover or mechanical method of press-fitting make drift both take into account heat-resistant antifriction, have good impact flexibility again simultaneously.The front end of main body 1 is provided with cooling holes 3, and these cooling holes 3 one ends run through from the front end face of main body 1, and the other end runs through from the side of main body 1.This cooling holes 3 is used to carry cooling fluid, and cooling fluid flows to from the side of ejector pin, flows out from front end, and cooling-down effect is better.
Though the utility model is through illustrating and describe with reference to preferred embodiment,, those skilled in the art should understand, and in the scope of claims, can do the various variation on form and the details.
Claims (2)
1. a drift comprises main body (1), it is characterized in that: the periphery of said main body (1) front end is equipped with alloy hoop (2), and the end face of outer face of this alloy hoop (2) and main body (1) front end is positioned at same plane.
2. drift according to claim 1 is characterized in that: the front end of said main body (1) is provided with cooling holes (3), and these cooling holes (3) one ends run through from the front end face of main body (1), and the other end runs through from the side of main body (1).
