Description

The radial forming processing system of a kind of light-wall pipe

Technical field

The present invention relates to process equipment, particularly the radial forming processing system of a kind of light-wall pipe.

Background technology

Thin-walled parts is applied in each industrial department increasingly extensively, because it has lightweight, feature such as saving material, compact conformation etc.But the processing of thin-walled parts compares stubborn problem in field of machining, and reason is thin-walled parts poor rigidity, and intensity is weak, the as easy as rolling off a log distortion of work in-process, makes the Form and position error of part increase, not easily ensures the crudy of part.Thin-walled plate part adds and easily occurs man-hour tilting, leaving the situations such as pit, makes part flatness, depth of parallelism equally accurate do not reach requirement.Light-wall pipe dress part then has clamping difficulty, to be easily distorted distortion, the problem that easily causes that part is crushed etc., makes the circularity of part, cylindricity, depth of parallelism equally accurate not reach requirement.

Summary of the invention

The object of the invention is to the shortcoming overcoming prior art, the radial forming processing system of the light-wall pipe providing a kind of structure simple, easy to use, this system can be used in the processing and forming of thin-walled tubular part, and its machining accuracy is high, part is not yielding.

Object of the present invention is achieved through the following technical solutions: the radial forming processing system of a kind of light-wall pipe, comprise brace table, several leads, several extrusion molding dies and the core for clamping blank, lead and extrusion molding dies are ringwise around being arranged in around brace table, lead is connected with extrusion molding dies wedge shape, core is arranged on above brace table, brace table is for supporting blank, extrusion molding dies is provided with forming surface, core is provided with core profile, and forming surface and core positive also make blank shaping by producing extruding.

Described lead and extrusion molding dies annular are around being arranged in core axis.

Described lead is fixedly mounted on brace table.

Described core and blank interference fit.

The present invention has the following advantages:

1. this system architecture is simple, easy to use, the direction of transfer of change power is connected by wedge shape, the feeding of vertical direction is changed into the feeding in horizontal direction, make to be achieved the punch process of thin-walled tubular part, multiple extrusion molding dies synchronizing moving is controlled to provide power by decompressor, from multiple directions, part is exerted a force simultaneously, can effectively prevent part from rotating man-hour adding, and uniform force application, make machining accuracy high, without the need to increasing extra power set to control the feeding of multiple mould, and can disposal molding be realized, be conducive to automated production, the labour intensity of operating personnel can be reduced,

2. the rigidity by using core to improve part, can effectively prevent part undesirable deformation, effectively can prevent parts turn in order to avoid affect machining accuracy, and clamping speed is fast, clamping is reliable simultaneously;

3. processing by using core to coordinate with extrusion molding dies, making forming parts precision high;

4. its part scope that can process is wide, can process completely to the thin-walled tubes part become by extrusion molding dies is evenly arranged, also extrusion molding dies can be arranged according to the mode corresponding with part, process the thin-walled tubes part with special shape.

Accompanying drawing explanation

Fig. 1 is the structural representation of the radial forming processing system of a kind of light-wall pipe;

In figure, 1-brace table, 2-lead, 3-extrusion molding dies, 31-forming surface, 4-blank, 5-core.

Detailed description of the invention

Below in conjunction with accompanying drawing, the present invention will be further described, and protection scope of the present invention is not limited to the following stated:

As shown in Figure 1, the radial forming processing system of a kind of light-wall pipe, it comprises brace table 1, several leads 2, several extrusion molding dies 3 and core 5, in the present embodiment, described extrusion molding dies 3 is provided with forming surface 31, core 5 is provided with core profile, lead 2 and extrusion molding dies 3 are ringwise around being arranged in around brace table 1, in the present embodiment, described lead 2 and extrusion molding dies 3 annular are around being arranged in core 5 axis ring, identical to the distance of core 5 axis with the forming surface 31 that this ensures on each extrusion molding dies 3, described lead 2 is fixedly mounted on brace table 1, lead 2 is connected with extrusion molding dies 3 wedge shape, extrusion molding dies 3 is connected with transmission device A, described transmission device A is punching mechanism in the present embodiment, transmission device A moves down for controlling extrusion molding dies 3, core 5 is arranged on above brace table 1, core 5 is connected with transmission device B, transmission device B moves down for controlling core 5, core 5 is made to pass blank 4, in the present embodiment, described core 5 is for clamping blank 4, described core 5 and blank 4 interference fit, ensure that blank 4 can firmly be clamped on core 5 with this, avoid blank 4 arbitrarily mobile or rotation, also make blank 4 shaping by producing extruding by forming surface 31 and core positive, transmission device B can select pneumatic actuator, hydraulic transmission or mechanical driving device, brace table 1 is for supporting blank 4.

The course of work of the present invention is as follows: be sent on brace table 1 by blank 4 by feed mechanism, control core 5 by transmission device B to move down, core 5 penetrates the endoporus of blank 4, external diameter due to core 5 is greater than the internal diameter of blank 4, core 5 can clamp blank 4 reliably, and enter at core 5 in the process of blank 4, coordinate the position adjusting blank 4 to accurate location by core 5 and blank 4.

After core 5 contacts with brace table 1, core 5 is stopped mobile, use transmission device A to control extrusion molding dies 3 to move down, because extrusion molding dies 3 is connected by wedge shape with lead 2, therefore when extrusion molding dies 3 moves down, can move, after the forming surface 31 on extrusion molding dies 3 contacts blank 4 to the direction near blank 4 simultaneously, continue to exert pressure, by the core positive on forming surface 31 and core 5 by extruded for blank 4.
