Abstract
The utility model discloses a composite pressure head component for sealing of circular pipes and belongs to the technical field of powder metallurgical hot isostatic pressing. The component comprises two composite pressure heads and two protection pads, each composite pressure head comprises a U-shaped operating face and a V-shaped cut, and the V-shaped cut of each composite pressure head is provided with one protection pad. The composite pressure head can be used for uniformly and reliably pressing and sealing circular pipes and cutting conveniently and is simple in structure.
Description
Technical field
The utility model relates to a kind of pipe sealing compound pressure head assembly, seals the compound pressure head assembly in particular for the hydraulic tongs of press seal aluminium pipe with pipe.Belong to powder metallurgy hot isostatic pressing technique field.
Background technology
The powdered metallurgical material jacket that needs to pack into before carrying out high temperature insostatic pressing (HIP) carries out vacuumize degassing, vacuumize degassing meets the requirements of the vacuum state that deaeration pipe must be sealed after the vacuum to keep in the jacket, the requirement of subsequent thermal isostatic pressing process be could satisfy, fine and close material or goods obtained.
At present the sealing of deaeration pipe is still carried out first the multi-pass press seal with general scissor Sealing pliers mostly, cut off again deaeration pipe and welded closure; For aluminum pipe in addition just at first hammering pound flat press seal, and then cut off deaeration pipe and welded closure.With scissor Sealing pliers carry out press seal and hammering pound the mode of flat press seal can be because the variation of the human factors such as operator's experience, state cause the reliability of deaeration pipe sealing lower, press seal can occur in real work frequently sternly do not cause the situation of jacket gas leakage, high temperature insostatic pressing (HIP) failure to occur, cause heavy losses.
Summary of the invention
In order to overcome the deficiency of existing press seal tool and method, the utility model provides a kind of hydraulic tongs for the press seal pipe to seal the compound pressure head assembly with pipe, this mould can cooperate existing hydraulic tongs to use, and utilizes the hydraulic tongs applied pressure to reach reliable press seal to pipe.
A kind of pipe sealing compound pressure head assembly, this assembly is comprised of two compound pressure heads and two protection cushion blocks, and each compound pressure head has a U-shaped working face and a V-arrangement edge of a knife simultaneously, and the V-arrangement edge of a knife of each compound pressure head is furnished with a described protection cushion block.
Described protection cushion block has the groove that can hold the V-arrangement edge of a knife.
Described protection cushion block is with alignment pin.
The protection V-arrangement edge of a knife was not crushed out of shape when described protection cushion block was used for press seal.
Described U-shaped working face is comprised of a rectangle plane and two ends one section cylinder tangent with it.
The described V-arrangement edge of a knife and described U-shaped working face are symmetrically distributed in the two ends of compound pressure head.
Described U-shaped working face is used for pipe is flattened, seals, and the described V-arrangement edge of a knife is used for pipe is cut off.
Described pipe is the aluminium pipe.
The hydraulic tongs that the utility model provides seals compound pressure head with pipe, and the use of fluid,matching pressing tongs is used for the press seal pipe.
The utility model designs a pair of flat envelope and shears compound pressure head as the pressure head that pipe is exerted pressure, under the promotion of hydraulic tongs push rod, compound pressure head U-shaped working face with move closer to after circular tube external wall contacts, seal needed gap and (be generally 0.5 ~ 2mm until reach pipe, decide on pipe wall thickness and seal request), general press seal 2 ~ 3 passages can seal the aluminium pipe.Behind the press seal, the pressure release of hydraulic tongs push rod with 180 ° of compound pressure head upsets, moves closer to after making its V-arrangement edge of a knife and circular tube external wall contacting, until pipe is cut off.The protection V-arrangement edge of a knife was not crushed out of shape when the protection cushion block was used for press seal.Pressure head appearance and size and the material of selecting can be carried out suitable variation according to the specification of pipe diameter, wall thickness and hydraulic tongs to be sealed.
The beneficial effects of the utility model are that the compound pressure head assembly that the utility model provides can carry out consistent, reliable press seal to pipe, and cuts off easily, and is simple in structure.

The specific embodiment
The following examples can make those skilled in the art more fully understand the utility model, but limit never in any form the utility model.
A kind of pipe sealing compound pressure head assembly, this assembly is comprised of two compound pressure heads and two protection cushion blocks, and each compound pressure head has a U-shaped working face and a V-arrangement edge of a knife simultaneously, and the V-arrangement edge of a knife of each compound pressure head is furnished with a described protection cushion block.
Described protection cushion block is with alignment pin.
Described U-shaped working face is comprised of a rectangle plane and two ends one section cylinder tangent with it.
The described V-arrangement edge of a knife and described U-shaped working face are symmetrically distributed in the two ends of compound pressure head.
Described U-shaped working face is used for the aluminium pipe is flattened, seals, and the described V-arrangement edge of a knife is used for pipe is cut off.
The hydraulic tongs that the present embodiment provides seals compound pressure head with pipe, and the use of fluid,matching pressing tongs is used for the press seal pipe.
In Fig. 2, under the promotion of hydraulic tongs push rod, compound pressure head U-shaped working face with move closer to after circular tube external wall contacts, seal needed gap and (be generally 0.5 ~ 2mm until reach pipe, decide on pipe wall thickness and seal request), general press seal 2 ~ 3 passages can seal the aluminium pipe.The protection V-arrangement edge of a knife was not crushed out of shape when the protection cushion block was used for press seal.
In Fig. 3, under the promotion of hydraulic tongs push rod, the compound pressure head V-arrangement edge of a knife with move closer to after circular tube external wall contacts, until pipe is cut off.
The above; it only is the better specific embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
