Description

technical field [0001] The invention relates to shock absorber processing equipment and a processing method, in particular to a shaping and punching device and a method for shaping and punching a steering knuckle bracket of an oil storage tank. Background technique [0002] The welding assembly of the oil storage tube of the shock absorber (referred to as the oil storage tube assembly), including the oil storage tube, the spring lower seat and the steering knuckle bracket, the mounting hole with high dimensional accuracy needs to be punched on the steering knuckle bracket, if the steering The dimensional accuracy of the mounting hole of the section bracket cannot meet the requirements, and when the shock absorber is installed on the car, it will affect the adjustment of the inclination angle; the traditional process and punching method have the following deficiencies: [0003] 1. Adopt the method of punching first and then welding, that is, punching the steering knuckle bra...

Problems solved by technology

[0003] 1. Adopt the method of punching first and then welding, that is, punching the steering knuckle bracket first, and then welding the steering knuckle bracket to the oil storage tank; this method requires high welding dimensions, and the benchmark for punching the steering knuckle bracket is the same The positioning references when welding the steering knuckle bracket to the oil storage tank are inconsistent, and the final measurement method is based on the oil storage tank, so the shape and position tolerance of the hole will not meet the requirements; the steering knuckle bracket is punched first and then welded has been phased out;

[0004] 2. Adopt the method of welding first and then punching, that is, welding the steering knuckle bracket to the oil storage tank first, and then punching the steering knuckle bracket with the oil storage tank as the reference; the measurement reference of this method is consistent with the punching reference, and can Effectively ensure the size requirements of the hole. Since the steering knuckle bracket and the oil storage cylinder are welded together, when punching holes, only the oil storage cylinder is used as the reference positioning. In the tooling design, the oil storage cylinder is usually positioned. It is designed for horizontal plane positioning or V-shaped block positioning, but since the oil storage tank is a welded pipe, it also has irregularities, and there will be slight deformation in the early process of the oil storage tank, so whether it is horizontal plane positioning or V-shaped block positioning , will be affected by the local deformation of the oil storage cylinder and affect the positioning reference, which will eventually lead to large fluctuations in the size of the punching hole, which will seriously affect the quality and production efficiency of the product;

[0005] 3. Secondly, the opening size of the steering knuckle bracket of the shock absorber (see attached Image 6 There is a requirement in H) of the steering knuckle bracket. Since the steering knuckle bracket is stamped and formed, considering the thermal deformation and shrinkage when it is welded to the oil storage tank, the opening size of the steering knuckle bracket will be larger than the actual required size when it is welded to the oil storage tank. After the oil storage tank, reshape to a suitable size; the above 1 and 2 punching methods require special shaping after punching, which affects production efficiency
