Detailed ways

The utility model provides a turning and forming device for special-shaped parts. The technical solutions of the present utility model will be described in detail below in conjunction with the accompanying drawings, so as to make it easier to understand and grasp.

A turning and forming device for a special-shaped part, as shown in FIG. 3 , the special-shaped part 1 includes a shaft body part 11 and a zigzag extension part 12 extending radially along the shaft body part 11 , and the shaft body part 11 is provided with an axial through hole 13 .

In the traditional processing technology, it is necessary to first prepare the embryo body of the special-shaped part 1 without the axial through hole 13, and then manually form the axial through hole 13, which is difficult to ensure the axial accuracy of the axial through hole 13, and The processing efficiency is very low.

In this case, as shown in FIG. 1 , the turning and forming device includes a feed shaft 2 , a running unit 3 for fixing the feed shaft 2 , a cutting mechanism 4 for radially cutting the feed shaft 2 , and an axial through hole 13 Shaped axial cutting mechanism 5.

The outer contour of the material shaft 2 matches the outer contour of the special-shaped part 1 . As shown in FIG. 2 , the operation unit 3 includes a clamp 6 that matches the outer contour of the material shaft 2 .

Specifically, first, according to the outer contour features of the profiled part 1, a specific material spool 2 is obtained, and the material spool 2 is a continuous main body and a non-cut individual.

Then, a specific clamp 6 is made according to the outer contour of the profiled part 1 , and the clamp 6 can stably clamp the material shaft 2 without clamping damage to the zigzag extension 12 .

The operation unit 3 realizes stable clamping and axial stabilization of the material shaft 2. After the axial through hole 13 is formed by the axial cutting mechanism 5, the shaped shaped part 1 is cut by the cutting mechanism 4 to ensure the axial direction. The forming accuracy of the through hole 13 also realizes the continuous production of the special-shaped part 1, and improves the product accuracy and production efficiency.

In a specific embodiment, as shown in FIG. 1 , the operation unit 3 includes a carrier 31 with a reciprocating operating displacement, and an auxiliary holder 32 for assisting the carrier 31 to perform displacement switching on the material shaft 2 . 31 and the auxiliary clamp base 32 are respectively provided with clamps 6 .

Specifically, when the exposed material shaft 2 running on the carrier 31 performs cutting and unloading of the shaped shaped part 1 , the material shaft is fixed by the auxiliary holder 32 , the clamp 6 of the carrier 31 is opened, and faces away from the axial cutting mechanism 5 . The direction is shifted to the appropriate clamping area to clamp the material shaft 2, and then the auxiliary clamping seat 32 releases the material shaft 2, and the carrier seat 31 clamps the material shaft 2 and then moves toward the axial cutting mechanism 5 to carry out the special-shaped part forming operation. This reciprocation realizes automatic production.

The switching displacement of the carrier 31 can be controlled to the axial dimension of a single profiled part 1 , so that the design can realize single step production without the aid of a displacement sensor.

The clamp 6 includes a first clamping end and a second clamping end with an opening and closing displacement, and a loading groove matching the outer contour of the material shaft is formed between the first clamping end and the second clamping end. Of course, it is not limited to several clamping ends, as long as the loading groove can be formed. As shown in FIG. 2 , in order to avoid clamping interference, two sides of the clamping end are different in height, so as to avoid the end block of the zigzag extending portion 12 .

In a specific embodiment, one end of the axial through hole 13 is provided with a conical chamfer 7, and the cutting end of the axial cutting mechanism 4 includes a cutting portion for forming the axial through hole and a conical chamfer forming. of the molding section.

In the drawings, the illustration of the cutting portion and the forming portion is omitted. Specifically, the cutting end only needs to be provided with an axial through hole 13 and a tapered chamfer 7 for one-step forming and turning.

Finally, the axial cutting mechanism 4 has an axial reciprocating displacement and a rotational turning displacement. With this design, there is no need to use the axial displacement of the operation unit 3 to assist the forming of the axial through hole 13, and the operation unit 3 only needs to be responsible for the stable clamping and feeding of the material shaft 2, which increases the turning stability.

From the above description, it can be found that the utility model is a turning and forming device for special-shaped parts, which can realize automatic continuous production of special-shaped parts, has high production efficiency, and improves the forming accuracy of axial through holes. Compared with the machining center, it has the characteristics of low equipment cost, which reduces the equipment investment and molding threshold for the production of special-shaped parts. The overall design is concise and ingenious, with strong pertinence, which can realize mass and efficient production of specific special-shaped parts.
