Abstract
The invention discloses a manufacturing method for a conical bottom. The manufacturing method comprises the following steps that blanking is performed according to the dimensional requirement of the conical bottom, and a sector is obtained; the sector is bent into a cone, and the small-diameter end is placed into a small cylinder of which the diameter is 1/2 that of the sector; a cylinder of which the diameter is 1.2-1.5 times that of the conical bottom is placed on the cone formed by bending the sector; and pressure is slowly applied on the cylinder till the sector is closed to form the conical bottom, full-length welding is performed, and then manufacturing of the conical bottom is completed. By the adoption of the method, operation is easy, and meanwhile the machining precision of the conical bottom is guaranteed.
Description
Technical field
The present invention relates to a kind of manufacture method of conical bottom.
Background technology
When current conical bottom manufactures, after sector blanking completes, owing to there is no process equipment, bending, welding can only be carried out by hand, not only complicated operation, and the precision of the frustum of a cone can not be guaranteed.
Summary of the invention
In order to overcome prior art Problems existing, the object of this invention is to provide a kind of manufacture method of conical bottom, adopting the method simple to operate, ensure that the machining accuracy of conical bottom simultaneously.
Object of the present invention is achieved through the following technical solutions:
A manufacture method for conical bottom, is characterized in that the method comprises the following steps:
1) by the dimensional requirement blanking of conical bottom, sector is obtained;
2) sector is bent to taper, smaller diameter end is put in little cylinder, and this little drum diameter is the half of sector diameter;
3) on the bending taper of sector, the cylinder that a diameter is cone bottom diameter 1.2 ~ 1.5 times is put;
4) slowly exert pressure on the cylinder, until covering of the fan closes, form conical bottom, full weld, conical bottom completes.
In the present invention, the material of conical bottom is plastics or steel.
The cylinder that a diameter is cone bottom diameter 1.4 times is put on the bending taper of sector.Slowly exert pressure on the cylinder, rotate sector simultaneously, until sector closes.
This invention exploits easy manufacturing process, simple to operate, ensure that the machining accuracy of conical bottom simultaneously.
Detailed description of the invention
A manufacture method for conical bottom, the method comprises the following steps:
1) by the dimensional requirement blanking of conical bottom, sector is obtained; The material of conical bottom can be plastics or steel;
2) sector is bent to taper, smaller diameter end is put in little cylinder, and this little drum diameter is the half of sector diameter;
3) on the bending taper of sector, the cylinder that a diameter is cone bottom diameter 1.4 times is put;
4) slowly exert pressure on the cylinder, rotate sector simultaneously, until covering of the fan closes, form conical bottom, full weld, conical bottom completes.
The present invention is simple to operate, ensure that the machining accuracy of conical bottom simultaneously.
