Description

Technical Field

[0001] The utility model relates to the field of trimming moulds, in particular to a trimming mould with adjustable size. Background Art

[0002] The existing trimming dies for long-axis forgings are generally rectangular, with a pad set on the top of the trimming die frame. The trimming die can be used by fixing it on the pad. However, in order to allow products of more sizes to fall smoothly from the middle of the pad, the size of the central avoidance area of ​​the pad is larger. For trimming dies for forgings with smaller lengths, since the trimming dies are not supported by the pad at both ends in the length direction, the trimming dies will be deformed along the center line during use, resulting in unqualified products processed by the trimming dies.

[0003] In order to make the trimming die frame applicable to trimming dies of various sizes and avoid deformation of the trimming dies, the utility model patent with the authorization announcement number CN114713749A specifically discloses an adjustable trimming die base, including a base, a first support body, a second support body, a first movable beam and a second movable beam; the first support body and the second support body are both slidably matched with the base along the first horizontal direction. The upper parts of the first support body and the second support body are both provided with sliding long holes along the second horizontal direction, and the two ends of the first movable beam and the second movable beam are respectively arranged in the sliding long holes and slidably matched; the first support body, the second support body, the first movable beam and the second movable beam form a frame structure, and the middle parts of the first movable beam and the second movable beam have an upper convex structure, and the top surfaces of the first support body and the second support body and the top surfaces of the upper convex structures of the first movable beam and the second movable beam respectively form support surfaces for supporting the four sides of the trimming die. The adjustable trimming die base has higher adjustability and can meet the trimming requirements of trimming dies of different specifications. However, the adjustable trimming die base needs to change the structure of the trimming die itself, and the trimming die needs to set up its own support structure, which makes the trimming die structure complex and the cost high.
