Problems solved by technology

Adopting such a process method for production, on the one hand, the thermal deformation generated during welding makes it difficult to guarantee the welding quality; on the other hand, the increase in processing procedures not only increases the scrap rate, but also leads to an increase in production workers, production equipment and production sites, thus Increased production cost of the product

Embodiment Construction

[0014] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0015] Such as figure 1 As shown, the axial feed mechanism 1 adopts a feed screw pair. On the one hand, the connection plate 4 is integrated with the axial feed mechanism 1, and is driven by the motor 22 to move in the axial direction; 5 is integrated with the feed plate 6, the left end of the anti-rotation pipe 2 is fixed on the head box 23 of the machine tool, and the four anti-rotation rods 3 on the right end are slidably matched with the connection plate 4, so that the connection plate 4 cannot rotate and can only be rotated along the axis. and drive the feed plate 6 for axial linear feed. The feed ring is divided into two parts, left and right. Connection, the axial slider 11 is designed to be wedge-shaped, and its end is connected to the right feed ring 8, and rolls around the feed disc 6, and simultaneously makes a linear feed motion a...

Abstract

The present invention relates to a spin forming method and its spin forming machine. The said method is characterized by that at the time when the spin wheel rotates with the main shaft of machine toal, the said spin wheel can make radial feeding movement along the direction perpendicular to the axis of the machine tool, and the blank not only can make linear feeding movement along longitudinal and transverse directions, but also can perform deflection movement in the horizontal plane at the same time. This invented equipment includes a spin wheel seat capable of making the spin wheel implement axial and radial feeding movements and a blank fixing chuck capable of implement horizontal shifting and turning. This invention can be used in special machine tool and also can be mounted on general machine tool.

Description

(1) Technical field [0001] The invention relates to the technical field of spinning forming in plastic processing, in particular to a spinning forming method and a device thereof. (2) Background technology [0002] Spinning is an important forming technology in the field of plastic processing. The traditional spinning technology uses the feed motion of tools such as rotary wheels to pressurize the metal blank that rotates along the same axis with the main shaft of the machine tool, so that it produces continuous local plastic deformation and becomes the required hollow axis symmetry ( Rotary body) parts. The non-axisymmetric eccentric, inclined and curved thin-walled hollow parts with axes parallel to each other or at a certain angle are usually made by stamping process, after forming the upper and lower parts, and then welding. . Adopting such a process method for production, on the one hand, the thermal deformation generated during welding makes it difficult to guarante...
