Abstract

The utility model discloses a pushing-rolling molding mold structure of a special-shaped steel pipe. The pushing-rolling molding mold structure mainly comprises a pipe bending wheel mold, a main shaft, a clamping wheel, a hinge pin, a clamping wheel seat, a handpiece crank arm, a guide wheel seat, a machine body and a guide wheel, wherein the main shaft is arranged at the upper end of the handpiece crank arm; the pipe bending wheel mold is arranged on the main shaft; the clamping wheel seat is arranged close to the left side of the lower end of the main shaft; the clamping wheel is arranged in the clamping wheel seat through the hinge pin; the guide wheel seat is arranged on the machine body; an installation guide wheel is arranged in the guide wheel seat through the hinge pin; and the clamping wheel and the guide wheel have the same structure, and can be replaced by each other. Due to the adoption of the pushing-rolling molding mold structure, the problem of subsequent assembling quality due to poor consistency and poor exchangeability of a pipe fitting caused by manual hot bending and the problems of the need of painting putty for remedying a defect due to poor appearance quality, and the like are solved, the production efficiency is greatly improved, and the manual production cost is lowered.

Description

A kind of steel tubes push away the volume forming die structure

Technical field

The utility model belongs to the panel beating field of steel tubes bending forming, and what relate to a kind of steel tubes pushes away the volume forming die structure.

Background technology

At present, some machining enterprises in China, the brake forming conventional machining process of non-round medium thickness pipe generally adopts the technology mode of manual hot bending, this processing mode not only production efficiency is low, labor strength is big, and the unstability of its machine-shaping tend to cause part and soldering member size inconsistent, make that its interchangeability is relatively poor, bring some problems to the later stage assembling, and coating process need increase and beats the putty operation and remedy the apparent defective of profiled member.

The utility model content

What the purpose of this utility model was to provide a kind of steel tubes pushes away the volume forming die structure, utilizes to push away to be rolled into the pattern tool, can significantly promote the pipe fitting bending quality, increases substantially production efficiency, reduces artificial production cost.

The technical solution of the utility model is: a kind of steel tubes push away the volume forming die structure, mainly comprise: bend wheel mould, main shaft, clip wheel, bearing pin, clip wheel seat, head are cranked arm, wheel stand, fuselage, guide wheel; The head upper end of cranking arm is equipped with main shaft, and bend wheel mould is installed on the main shaft, and the main shaft lower end side of taking back is equipped with the clip wheel seat, and clip wheel is installed in the clip wheel seat by bearing pin, and wheel stand is installed on the fuselage, and guide wheel is installed in the wheel stand by bearing pin.Clip wheel is identical with Guiding wheel structure.

The utility model can reach following beneficial effect: use this to push away the volume forming die structure, pipe fitting uniformity, the next postorder assembly quality problem of interchangeability difference band that manual hot bending causes have significantly been improved, and the presentation quality difference need be beaten problems such as putty supplies a gap, significantly improve production efficiency, reduced artificial production cost.

Fig. 2 is that (2: 1) schematic diagram is amplified in the H-H cross section among Fig. 1.

The specific embodiment

The utility model is described in further detail with reference to the accompanying drawings below.

As depicted in figs. 1 and 2: a kind of steel tubes push away the volume forming die structure, mainly comprise: bend wheel mould 1, main shaft 2, clip wheel 3, bearing pin 4, clip wheel seat 5, head crank arm 6, wheel stand 7, fuselage 8, guide wheel 10; Head 6 upper ends of cranking arm are equipped with main shaft 2, bend wheel mould 1 is installed on the main shaft 2, and the main shaft 2 lower ends side of taking back is equipped with clip wheel seat 5, and clip wheel 3 is installed in the clip wheel seat 5 by bearing pin 4, bend wheel mould 1 has the plane and rotatablely moves, clip wheel 3 have move up and down and the plane rotatablely move; Wheel stand 7 is installed on the fuselage 8, and guide wheel 10 is installed in the wheel stand 7 by bearing pin 4, and guide wheel 10 has horizontal rectilinear motion and the plane rotatablely moves.Clip wheel 3 is identical with guide wheel 10 structures.

In the present embodiment, shape tube 9 carries out the design of branch mould after pipe fitting rotates 31 °, form shape tube 9 mold cavities jointly by bend wheel mould 1 and clip wheel 3, guide wheel 10, thereby finish the brake forming of the space composite molding radian that 9 radians of shape tube and front window radian be together to form.

During work: behind shape tube 9 material loadings, bend wheel mould 1 and clip wheel 3, guide wheel 10 form die region clamping shape tube 9, at the mould rear feeding trolley is arranged, beam tube clamp device clamping shape tube 9 tail ends on it guarantee the tram of shape tube 9 in the mould clamping process; Promote the die region of shape tube 9 by feeding trolley in the moulding by bend wheel mould 1, clip wheel 3 and guide wheel 10, the formation of moulding radian is to be cranked arm by the head at bend wheel mould 1 and clip wheel 3 places 6 to rotate to an angle around main shaft 2, form the composite space moulding radian of finally finishing shape tube 9 with certain angle of guide wheel 10, wherein the size of angle is adjustable.

In addition, the utility model uses equal dies to require to finish by numerical control moulding change of program according to the product different designs, has certain flexible working ability, and production efficiency height, steady quality, uniformity, interchangeability are good, can satisfy the productive temp requirement of market fast transformation and new product debugging demand and batch process.
