Abstract
The utility model provides a two-sectional sizing working tape porthole die for an aluminum alloy extruded pipe, and belongs to the technical field of rail transportation facilities. The porthole die is characterized in that a second section of sizing working tape extends in back of a first section of sizing working tape of an upper die. The two-sectional sizing working tape porthole die for the aluminum alloy extruded pipe has the beneficial effects that the two sections of sizing working tapes are arranged on the upper die, and the second section of sizing working tape has the roles of modifying the circular degree of the pipe and removing metal particles formed on the inner surface of the pipe due to overheat during extruding, so that the follow-up treatment can be saved, the producing cost is reduced, and the production efficiency can be improved.
Description
Technical field
The utility model belongs to the Transit Equipment technical field.
Background technology
At present, when producing large-diameter aluminium alloy pipe, the diffluence combination die extrude tubes of use, diffluence combination die is made of upper die and lower die.Be subjected to the impact of mould structure and extrusion process characteristic, the tubing of producing under high temperature, high pressure oval phenomenon often occurs and inner surface is stained with a small amount of small metallic particles, affects product quality.For the metallic particles that the ellipse of eliminating product and inner surface are stained with, common way is that product is carried out follow-up processing, does like this to have more a procedure, increases production cost.
The patrix sizing work band of diffluence combination die commonly used is one section, and the internal diameter of the sizing work band shaping pipe of patrix, the external diameter of the sizing work band shaping pipe of counterdie, metal form tubing after by the space between the sizing work band of upper die and lower die, see Fig. 1.
Summary of the invention
The purpose of this utility model is: provide a kind of aluminum alloy extruded tube with two sections sizing work band diffluence combination dies, it can overcome and occurs oval phenomenon when producing large-diameter aluminium alloy pipe and inner surface is stained with a small amount of small metallic particles problem.
The technical solution of the utility model is: be extended with second segment sizing work band behind patrix first paragraph sizing work band.
The beneficial effects of the utility model are: patrix has two sections sizing work bands, second segment sizing work band wherein can play shaping tubing circularity, remove in the extrusion process because the effect of the overheated metallic particles that occurs at internal surface of pipe, no longer need follow-up processing, reduced production cost, enhanced productivity.
Description of drawings
Fig. 1 is the sizing work band structure cutaway view of existing combination die upper die and lower die;
Fig. 2 is the utility model front view;
Fig. 3 is the utility model A-A cutaway view;
Fig. 4 is that the utility model counterdie is with the X phantom of second segment sizing work band.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1, the 1st, the sizing work band, the 2nd of counterdie, the sizing work band of patrix;
As shown in Figure 3, the 3rd, counterdie, the 4th, patrix;
As shown in Figure 4, the 5th, the sizing work band, the 6th of counterdie, the first paragraph sizing work band, the 7th of patrix, the second segment sizing work band of patrix.
Patrix leaves a segment distance behind first paragraph calibrating strap 6, and then to add the preceding paragraph calibrating strap be second segment sizing work band 7.Metal is after extruding first paragraph calibrating strap 6 and becoming tubing, and by second segment sizing work band 7 time, second segment sizing work band 7 can play the ovalizing deflection of revising tubing, scrape the effect of the metallic particles that inner surface is stained with.
