A thin-walled tube radial forming processing system

technical field

The utility model relates to processing equipment, in particular to a thin-walled pipe radial forming processing system.

Background technique

Thin-walled parts have been increasingly widely used in various industrial sectors because of their light weight, material saving, and compact structure. However, the processing of thin-walled parts is a difficult problem in the field of mechanical processing. The reason is that thin-walled parts have poor rigidity and weak strength. Thin-walled plate-like parts are prone to warping and pits during processing, which makes the flatness and parallelism of the parts less than the required precision. Thin-walled tube-mounted parts have problems such as difficult clamping, prone to distortion and deformation, and easy to cause the parts to be flattened, so that the accuracy of the roundness, cylindricity, and parallelism of the parts cannot meet the requirements.

Utility model content

The guide column and the extrusion mold are arranged around the axis of the mandrel.

The guide column is fixedly installed on the support platform.

The core mold is in interference fit with the blank.

The utility model has the following advantages:

1. The system is simple in structure and easy to use. The transmission direction of the force is changed through the wedge connection, and the feed in the vertical direction is converted into the feed in the horizontal direction, so that the stamping process of thin-walled tubular parts can be realized. The stamping device Control multiple extrusion molds to move synchronously to provide power, and apply force to the parts from multiple directions at the same time, which can effectively prevent the parts from rotating during processing, and the force is uniform, so that the processing accuracy is high, and there is no need to add additional power devices to Control the feeding of multiple molding dies, and can realize one-time molding, which is conducive to automatic production and can reduce the labor intensity of operators;

2. By using the mandrel to increase the rigidity of the parts, it can effectively prevent the bad deformation of the parts, and at the same time, it can effectively prevent the rotation of the parts so as not to affect the processing accuracy, and the clamping speed is fast and reliable;

3. By using the core mold and the extrusion molding mold to cooperate with the processing, the forming precision of the parts is high;

4. It can process a wide range of parts. By arranging the extrusion molding dies evenly, it can process completely paired thin-walled pipe parts. It can also arrange the extrusion molding dies in a way corresponding to the parts to process special Shaped thin-walled tubular parts.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described, and the protection scope of the utility model is not limited to the following:

As shown in Figure 1, a thin-walled tube radial forming processing system, it includes a support table 1, a number of guide columns 2, a number of extrusion molds 3 and core mold 5, in this embodiment, the extrusion The compression molding die 3 is provided with a forming surface 31, the core mold 5 is provided with a core mold surface, and the guide post 2 and the extrusion molding die 3 are arranged around the support table 1 in a ring shape. In this embodiment, the guide post 2 and the extrusion mold 3 are annularly arranged around the axis of the core mold 5 to ensure that the distance from the molding surface 31 on each extrusion mold 3 to the axis of the core mold 5 is the same, and the guide column 2 is fixedly installed On the support platform 1, the guide column 2 is wedge-shaped connected with the extrusion molding die 3, and the extrusion molding die 3 is connected with the transmission device A. The transmission device A is a stamping mechanism in this embodiment, and the transmission device A is used to control The extrusion molding mold 3 moves downward, and the core mold 5 is arranged above the support table 1. The core mold 5 is connected with the transmission device B, and the transmission device B is used to control the downward movement of the core mold 5 so that the core mold 5 can pass through the blank 4 , in this embodiment, the core mold 5 is used to clamp the blank 4, and the core mold 5 and the blank 4 have an interference fit, so as to ensure that the blank 4 can be firmly clamped on the core mold 5 to avoid The blank 4 moves or rotates at will, and the blank 4 is formed by cooperating with the core model surface through the forming surface 31 and extrusion. The transmission device B can be a pneumatic transmission device, a hydraulic transmission device or a mechanical transmission device, and the support table 1 is used to support the blank 4.

The working process of the utility model is as follows: the blank 4 is transferred to the support table 1 through the feeding mechanism, the mandrel 5 is controlled by the transmission device B to move downward, and the mandrel 5 penetrates into the inner hole of the blank 4. The diameter is larger than the inner diameter of the blank 4, the core mold 5 can reliably clamp the blank 4, and when the core mold 5 enters the blank 4, the position of the blank 4 can be adjusted to an accurate position through the cooperation between the core mold 5 and the blank 4.

When the core mold 5 is in contact with the support table 1, the core mold 5 stops moving, and the transmission device A is used to control the extrusion molding mold 3 to move downward. Since the extrusion molding mold 3 and the guide column 2 are connected in a wedge shape, when extrusion When the forming die 3 moves downward, it will move towards the direction close to the blank 4 at the same time. When the forming surface 31 on the extrusion forming die 3 touches the blank 4, the pressure will continue to pass through the forming surface 31 and the core model on the core mold 5. Surface fitting is used to extrude the blank 4 .
