A kind of automobile engine suspension bracket and preparation method thereof

Abstract

The invention aims at providing an automobile engine mounting bracket and a manufacture method thereof. The automobile engine mounting bracket comprises a base, a support plate, a bracket, an installing hole and a suspending hole, wherein a bending part is arranged on the support plate. According to the automobile engine mounting bracket, the special bending part is adopted, and thus parts structures in an automobile can be avoided, larger operation space is provided for automobile design, especially for a compact automobile, a better design flexibility is achieved; and meanwhile, the shape and the structure ensure enough support strength, and thus the stability of an automobile engine mounting assembly is ensured. The invention also provides a manufacture method of the mounting bracket. By using a specially designed discharging block, the stability in a machining process is ensured; and due to the arrangement of a locating hole and a locating edge, a corresponding locating module is arranged on a matched forming mould, the machining precision can be well ensured, and excessive thinning and cracking on the thickness of parts materials during machining are avoided, and better practicability is achieved.

Description

technical field [0001] The invention relates to the mechanical field, in particular to an automobile engine suspension bracket and a preparation method thereof. Background technique [0002] At present, in order to ensure that there are no cracks and no excessive thinning during stamping and forming (thinning < plate thickness * 15%), the engine suspension support is usually designed as a symmetrical structure. This can ensure that the steel plate is evenly stressed during stamping, and can effectively avoid the risk of punching cracks and thinning. However, in the actual application process, due to the need to avoid surrounding parts, or when combined with the unique design inside the car body, the support frame with a symmetrical structure cannot meet the needs, and the support frame with an asymmetric structure is difficult due to uneven force during stamping. Forming is easy to crack and thin at the bend, so it cannot meet the design requirements and cannot meet the ...
