Problems solved by technology
[0002] In the production process, it is often necessary to process some workpieces with relatively complex shapes, such as a Z-shaped spring workpiece. For the Z-shaped workpiece bending process, if a general mold is used, it usually needs to go through two processes. If this is the case, the positioning is difficult and the production efficiency also lower
Moreover, for an asymmetrical workpiece like the Z type, the punch of the mold is greatly damaged during the working process, resulting in a reduction in the service life of the mold

The invention discloses a spring curve mould which comprises a mould base, a concave mould and a convex mould. The spring curve mould is characterized in that the concave mould is arranged on the mould base, the convex mould is arranged above the concave mould, a spring is arranged at the lower portion of the concave mould, the top of the spring is connected with a lower mould, locating plates capable of laterally moving are arranged at the top of the concave mould, the locating plates are located on the two sides of the lower mould, and the limiting position reached when the convex mould descends is higher than the lowest point of the corner of the lower mould. The spring curve mould is simple and reasonable in structure, practical and stable, can complete processing of an asymmetry workpiece at one time, so that production efficiency is improved, meanwhile the limiting position reached when the convex mould descends is set to be higher than the lowest point of the corner of the lower mould, and the convex mould is protected, so that the service life of the mould is prolonged. The spring curve mould can process workpieces of different shapes by replacing the lower mould, thereby being wide in application range.
Description
technical field [0001] The invention relates to a mold, in particular to a spring bending mold. Background technique [0002] In the production process, it is often necessary to process some workpieces with relatively complex shapes, such as a Z-shaped spring workpiece. For the Z-shaped workpiece bending process, if a general mold is used, it usually needs to go through two processes. If this is the case, the positioning is difficult and the production efficiency Also relatively low. Moreover, for an asymmetrical workpiece like the Z shape, the punch of the mold is greatly damaged during the working process, resulting in a reduction in the service life of the mold. Contents of the invention [0003] Purpose of the invention: the purpose of the invention is to provide a spring bending die. [0004] Technical solution: In order to achieve the above object, the present invention adopts the following technical solution: [0005] A spring bending die, comprising a die base, ...
