Sheet Metal Design Feature

The features have the nature of parameterization, and their features are expressed in the way of parameters. Engineers establish a feature library in advance, which includes the features of parts commonly processed by sheet metal, such as flat plates, holes and grooves of various methods. Planning is to first input all the information of parts, select the matrix features in the feature library, generate matrix features, and take this as the basis for feature equipment modeling. Then the required features are selected from the feature library, the feature parameters and positioning parameters are given through the feature parameter table and positioning parameter table, and the feature equipment is carried out to establish the shape feature model.

Design Criteria of Sheet Metal Structure

According to the problems encountered in the actual machining process, the problems needing attention in the structural design of sheet metal are discussed from the following aspects, and the corresponding design criteria are given. Selection Criteria of Sheet Metal Materials Sheet metal is generally used for the installation of equipment shell and electrical circuit, so it is very important for the selection of sheet metal. Proper selection is not only conducive to processing, but also can reduce the cost on the premise of ensuring the strength. (1) In order to ensure the material utilization rate and the minimum number of die changes in bending, the thickness specifications of plates on the same structure shall not exceed three at most. For structures with high strength requirements, the method of pressing reinforcement on thin plates can be adopted; (2) It should be avoided that the unfolding size of parts is equal to the outline size of raw materials: the shape of plate...

Four Basic Cold Processing Links to Optimize Sheet Metal Design

Generally, sheet metal parts have obvious advantages in strength, weight and cost, and have better point-to-point performance than traditional parts. Therefore, up to now, sheet metal parts have been gradually applied in China’s high-tech fields such as electronics and communication. At the same time, people have gradually put forward higher requirements for the quality and function of sheet metal parts, The proper optimization of the original sheet metal processing technology has become the focus of sheet metal processing personnel. According to the actual research, this paper believes that the optimization of processing technology should be carried out one by one from the application of four basic cold processing links of sheet metal processing. 1 Blanking First of all, as far as the blanking link is concerned, generally speaking, blanking refers to the separation of sheet metal materials through the stamping of the die, so as to realize the separation of she...

Semi-automatic Sheet Metal Production Line

At this stage, most of the production in the chassis and cabinet industry uses single machine production, including laser cutting machine, plasma cutting machine, plate shears, CNC punching, bending machine, oil press, riveting machine, argon arc welding machine, electric welding machine, laser welding, surface treatment equipment, etc. these equipment require a lot of labor and have low production efficiency. With the increasing labor costs and the increasingly standardized safety protection regulations, the chassis and cabinet industry urgently needs to change the current situation. Intelligent storage warehouse of sheet metal + automatic feeding + laser cutting machine + automatic cutting and automatic dividing. The other side of the warehouse can be punched by numerical control. It is best to use laser compound punching (manual cutting), automatic grinding, bending machining center (bending by robot), and another numerical control bending machine is equipped, fol...
