Embodiment Construction

[0026] The present invention utilizes three-roll plate rolling machine to roll out AFDC ( figure 1 , figure 2 , the AFDE shown is a positive conical shell and image 3 The shown AFA'E'DE is a forward conical shell expansion diagram); at this time, the large end surface of the conical shell is an ellipse, and the sample is measured by the inner arc of the large end, as Figure 4 As shown, the conical shell is corrected on the three-roll plate rolling machine, so that the large end face is corrected as a circular end face; after the correction, the AFB part is cut off to obtain the eccentric cone shell ABDC.

[0027] The invention is applicable to eccentric conical shells with different angles.

[0028] The specific implementation steps of the present invention are as follows:

[0029] (1) Draw the front view according to the size of the neutral layer of the eccentric conical shell to be manufactured, namely figure 1 In the ABDC section. It is also possible to draw its top...

Abstract

The invention discloses a manufacture method of an eccentric cone shell, which adopts a method of adding supplementary material at the small port end of the eccentric cone shell to make a main view, avertical view and an expansion view of the required eccentric cone shell according requirements. By utilizing a three-roller plate bending roll to roll according to a method for rolling a positive cone shell, the big end surface of the cone shell is an oval; and then by utilizing an inner circular arc measurement sample plate at the big end to conduct correction to the cone shell on the three-roller plate bending roll so as to lead the big end surface to be corrected into a circular end surface and to cut off the supplementary material part after correction, the eccentric cone shell can be obtained. By utilizing the three-roller plate bending roll, the eccentric cone shells with different specifications can be processed, and the manufacture method of the eccentric cone shell has high efficiency and strong versatility, saves the cost, reduces the labor intensity, improves the work efficiency, and is applicable to the manufacture of the eccentric cone shells with different included angles.

Description

technical field [0001] The invention relates to a manufacturing method, in particular to a manufacturing method of an eccentric cone shell. Background technique [0002] At present, the known manufacturing method of the eccentric conical shell (that is, the horseshoe-shaped horn) is a compression molding method, which utilizes a press and a corresponding supporting mold to perform compression molding. From the working principle and process of this method, it can be known that the manufacture of eccentric cone shells of different specifications needs to be equipped with corresponding molds, which requires a large investment and low utilization rate of the molds. Especially for single piece and small batch production, it seems that the efficiency is extremely low. Second, in the process of pressing and forming, the staff need to adjust the position of the workpiece and the tire multiple times in order to complete the entire forming process. Third, if a batch of eccentric con...
