Description

Technical Field

[0001] The invention relates to the technical field of mold manufacturing design, and in particular to a hook punch wedge design method based on UG software, a medium and an electronic device. Background Art

[0002] In the production process of cold stamping sheet metal, the punching process angle that cannot be achieved by the vertical movement of the punch press needs to be converted into horizontal movement. The industry named this motion mechanism as a wedge. Due to the spatial position restrictions of sheet metal and production operation requirements, wedges are divided into multiple types, and hook punch wedges are one of them. In recent years, some hook punch wedge standard parts have been launched on the market, but they are expensive and have few models and specifications, which cannot meet the requirements of mold design. Therefore, the mold manufacturing industry mostly uses self-made designs, and the structural design engineers draw the required three-dimensional mechanism parts according to the sheet metal blanking process design.

[0003] However, the inventors of this application found that the above technology has at least the following technical problems in the process of implementing the technical solution of the invention in the embodiment of this application:

[0004] During the design and drawing process, it is usually necessary to use multiple UG commands in combination to draw multiple 3D parts such as sliders, drive blocks, return hooks, and limiters. During design, it is necessary to calculate the horizontal and vertical motions of the inclined wedge slider required for the sheet metal based on trigonometric functions. The designer needs to call the standard guide plate of the corresponding brand for the slider according to customer requirements and motions. This design method relies on experience and design level, and is difficult to design. In addition, manual drawing cannot preview the design effect of 3D parts globally. The various components of the mechanism are interrelated. Once the prediction is insufficient, the structure of all components will be modified. This design method is inefficient.

Step S2, based on the slider parameter information generated in Step S1, the slider parameter information includes length, height, width, blanking angle, punch position, nitrogen position, guide plate length, wear-resistant plate height, and pressure strip guide plate model; automatically arrange the guide plates, limit glue, and return hook components: in the UG function operation interface, select the generated slider, calculate the number of guide plates to be placed and the corresponding length through the length and width of the slider bottom surface and the length and width of the side guide plate mounting surface, and at the same time read the center position of the slider bottom surface and the slider side surface, and place the limit glue;

[0035] Predefine the corresponding installation area positions and fixed installation normals of the guide plate, limit rubber and return hook components to quickly locate the matching of the area center position.

[0036] The method for generating the slider and the driving block in step S1 includes:

[0037] Step S11, in the UG software function operation interface, select the bottom surface of the workpiece for sheet metal blanking; the angle formed by the projection vector of the normal vector of the bottom surface of the workpiece on the XOY plane is defined as angle A, and according to the use range of the hook punch wedge mechanism, angle A is within In the range of , it is classified into the following two cases, and the key parameters are obtained: the angle B between the bottom surface of the slider and the driving surface;

[0038] when When , the angle B between the bottom surface of the slider and the driving surface is
