Abstract
The utility model discloses a stepped expansion pipe mold special for a pipe expander. The stepped expansion pipe mold comprises a body, and is characterized in that a stepped expansion valve is arranged on the body; and furthermore, the stepped expansion valve is divided into two parts, namely a first expansion valve and a second expansion valve; and the first expansion valve is connected with the body. The expansion valve adopts a stepped mode, a set of expansion tool can finish the processing of a product with the size of the required secondary expansion hole when mounted at a time, and the mold is conveniently and rapidly used; and meanwhile, the mold cost is saved, the frequency of replacing the mold is reduced, the working efficiency is improved, the frequency for workers to replace the mold is reduced, and the labor intensity is lightened.
Description
Technical field
The utility model belongs to mould applications, specifically, relates to the special-purpose staged expand tube of a kind of electric tube expander mould.
Background technology
Along with the progress of society and people improve the requirement of quality of the life, the use of automobile is more and more universal, and automobile industry and auto parts and components processing enterprise have also obtained greatly opportunity to develop thereupon.At present, the automobile exhaust system expand tube processing mold in the automobile generally can only satisfy the needs that once expand, and travel range 5-7mm surpasses 7mm for bloated hole stroke, will change the bloated tool of second cover, just can reach dimensional requirement.Sometimes make a kind of product, just must use two covers, or even the above bloated punch die of two covers.Alternately change the punch die that expands back and forth, both wasted great amount of time, reduced efficiency, increase working strength of workers again.
Summary of the invention
The technical problem that the utility model will solve is to overcome above-mentioned defective, provide a kind of easy to make, can process multiple bloated hole, the special-purpose staged expand tube of the electric tube expander that reduces production costs mould.
For addressing the above problem, the technical scheme that the utility model adopted is:
The special-purpose staged expand tube of a kind of electric tube expander mould comprises body, it is characterized in that: said body is provided with the bloated lobe of staged.
Say further:
The bloated lobe of said staged is divided into the first bloated lobe and second bloated lobe two parts, and the first bloated lobe is connected with body.
Owing to adopted technique scheme, compared with prior art, the bloated lobe of the utility model is designed to staged; Satisfy installation once the bloated tool of cover and once can accomplish the bloated hole dimension product processing of required secondary, convenient to use, simultaneously; Practice thrift die cost, reduce the die change number of times, increase work efficiency; Reduce more mold exchange number of times of workman, reduce labor intensity.
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further simultaneously.
Description of drawings
Accompanying drawing is the structural representation of a kind of embodiment of the utility model.
Among the figure: the 1-body; The 2-first bloated lobe; The 3-second bloated lobe.
The specific embodiment
Embodiment:
The special-purpose staged expand tube of a kind of electric tube expander mould shown in accompanying drawing, comprises body 1, and said body 1 is provided with the bloated lobe of staged.The bloated lobe of said staged is divided into the first bloated lobe 2 and second bloated lobe 3 two parts, and the first bloated lobe 2 is connected with body.
Staged expand lobe can with the mould one, also can be fixed together through fixed connecting piece.Concrete which kind of connected mode that adopts is confirmed according to actual conditions.
In reality processing, the travel range of the utility model rises to 10-12mm, has realized the purpose in the different holes of expanding of the bloated tool processing of a cover; Avoided alternately changing back and forth the punch die that expands; Practice thrift great amount of time, improved efficiency, alleviated working strength of workers again.
Claims (2)
1. the special-purpose staged expand tube of an electric tube expander mould comprises body (1), it is characterized in that: said body (1) is provided with the bloated lobe of staged.
2. the special-purpose staged expand tube of electric tube expander as claimed in claim 1 mould is characterized in that: the bloated lobe of said staged is divided into the first bloated lobe (2) and second bloated lobe (3) two parts, and the first bloated lobe (2) is connected with body (1).
