Embodiment Construction

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are the Some embodiments of the invention are not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0019] The principle of the present invention is as follows: the present invention has changed the previous processing method of spring rolling and forming, and appropriately relaxes the strict restrictions on the shape of the spring including roundness and helical lead, because these restrictions have little influence on the elastic effect of the spring, but A simple...

Abstract

The invention provides a non-rolling forming forging and pressing die for a spring and a forming method. The forging and pressing die comprises a first die body and a second die body. The two-time forging and pressing process is achieved through the first die body and the second die body respectively, process equipment for spring machining is greatly simplified, the spring can be machined on a common crank press, and special spring machining equipment is not needed. In addition, the conventional rolling process belongs to a process method similar to grinding or rolling, but the forging and pressing process method of the spring is truly implemented, a high-efficiency spring processing mode is formed, and the method is more suitable for large-scale spring part manufacturing in assembly line work.

Description

technical field [0001] The invention belongs to the technical field of rolling and forming methods for springs, and in particular relates to a forging die and a forming method for non-rolling and forming of springs. Background technique [0002] The forming method of spring is generally rolling, and rolling requires special machine tools or equipment, because the longitudinal feed and rotational motion required for rolling are coupled, so these machine tools often require complex transmission systems, and, Some spring rolling systems also require many manipulators to operate. In order to reduce the cost of equipment and simplify the production process, it is necessary to use simple molds on more general equipment to adapt to the high-efficiency processing of springs. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide a non-rolling forming method of spring and its forging die, the forming method has few steps and simple p...
