Description

Device for extruding branch pipe on pipeline

Technical Field

The utility model relates to a branch pipe processing technology, especially a disposable branch pipe forming technique, specifically speaking are device of extrusion branch pipe on the pipeline.

Background

In the prior art, the branch pipe processing on the main pipeline is realized by adopting a method of welding a branch pipe table or a pipe forging machine to process a pipe nozzle. Welding defects easily exist in the branch pipe welding table, and due to the fact that welding seams exist between the branch pipes and the main pipe, overall performance of materials is uneven, and service life of products is affected; machining nozzles are not standard per se, and in addition, raw material waste is very serious in order to meet the wall thickness of the machining nozzle. Through reasonable design of a forming process and a forming die, the branch pipe and the main pipe are integrally connected, and the size and the precision of a product are ensured to meet the requirements of drawings.

SUMMERY OF THE UTILITY MODEL

The utility model aims at having the problem of inefficiency or the unable guarantee of quality to current branch pipe shaping, utility model a method of manifold takes shape on the pipeline provides a corresponding forming device simultaneously, guarantees that the branch pipe height that takes shape, wall thickness and branch pipe distribution satisfy the requirement of drawing and technical condition, replaces the product that adopts welding process or machine tooling branch pipe to make in the past, improves product wholeness ability to improve product productivity effect.

The technical scheme of the utility model is that:

a device for extruding branch pipes on a pipeline is characterized by comprising an upper die 1, a core rod 2, a punch 3, a cushion block 4 and guide holes 5, wherein branch pipe blind holes are distributed on the upper die 1, the size of each branch pipe blind hole is consistent with the size of a branch pipe preformed on the pipeline, and the distance between the branch pipe blind holes is consistent with the distance between the branch pipes preformed on the pipeline; grooves for fixing the punch 3 are processed on the core rod 2, and the distance between the grooves is consistent with that between the branch pipe holes.

Guide holes 5 are processed on the upper die 1 and the core rod 2, and guide columns are installed in the guide holes.

The utility model has the advantages that:

the utility model discloses the method is simple and easy, and device simple structure does benefit to the realization, through rational design mould and forming process, guarantees that the branch pipe height that takes shape, wall thickness and branch pipe distribution satisfy the requirement of drawing and technical condition, improves product wholeness ability to improve product productivity effect.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples.

The first embodiment.

A method for extruding branch pipes on a pipeline comprises the steps of firstly placing an upper die on the upper portion of a main pipeline, simultaneously supporting the main pipeline on a cushion block, arranging a blind hole matched with the branch pipe to be formed on the upper die, then inserting a lifting core rod into the main pipeline, arranging a groove for placing a punch on the core rod, and placing the punch in the groove; thirdly, connecting the upper die with the core rod by using a guide pin; and finally, starting the press to enable the core rod to move upwards along the guide pin, enabling the punch to penetrate through the main pipeline and drive the pipe to enter the blind hole of the upper die to form branch pipes, forming a series of small-size branch pipes in axially equidistant and circumferentially equiangular distribution along the main pipeline, and integrally connecting the branch pipes with the main pipe. In order to prevent the branch pipe from cracking in one extrusion forming process, the specific implementation can be realized by replacing different punches for multiple times to gradually form the branch pipe, and heat treatment is carried out after each extrusion forming process to eliminate stress.

Example two.

As shown in figures 1, 2 and 3.

A device for extruding branch pipes on pipelines comprises an upper die 1, a core rod 2, a punch 3, a cushion block 4 and guide holes 5, wherein as shown in figure 1, branch pipe blind holes are distributed on the upper die 1, the size of each branch pipe blind hole is consistent with the outline size of a branch pipe preformed on the pipeline, and the distance between the branch pipe blind holes is consistent with the distance between the branch pipes preformed on the pipeline, as shown in figure 2; grooves for fixing the punch 3 are processed on the core rod 2, and the distance between the grooves is consistent with that between the branch pipe holes. Guide holes 5 are processed on the upper die 1 and the core rod 2, and guide columns are installed in the guide holes.

The details are as follows:

the utility model discloses a key is in place on the specific recess of plug 2 drift 3, then place plug 2 on cushion 4 to fix plug 2 on hydraulic equipment, then insert a stick in the locating hole 5 of mould 1, pipe, plug 2 (as shown in figure 1), through upwards moving core wedge 2, realize taking shape of branch pipe.

The utility model discloses the part that does not relate to all is the same with prior art or can adopt prior art to realize.
