In order to improve design and drawing efficiency, reduce the difficulty of design structure, and facilitate inspection, stamping die designers will use secondary development programs for auxiliary drawing.
CAD is the most common design software in the design of two-dimensional stamping dies. Naturally, there are more secondary development softwares that match it. Among them, the most familiar to designers is "PressCAD". More than 80% are aware of this secondary development program.
Although the mold design becomes simple after loading the program, the software itself is more complicated. In addition, you will encounter various problems in the use of the program. Here, I will talk to you about some common problem solutions about PressCAD.
1. Use the command to change the diameter of the attribute circle hole, but the brush annotation diameter has not been changed?
Method: The size label must be used to change it to be effective. As shown
2. There are layers, why are all the painted primitives of the same color?
Method: You can check whether the primitive is not divided into the corresponding layer at the beginning of drawing or whether the color of the primitive is following the layer. As shown below
3. A question mark is displayed when you brush the comment, and font adjustment is required to solve it?
Method: Enter the command STT or click the icon, or create a complete template yourself and save it. Ensure that all future drawings are in the template drawing to avoid problems.
4. Can't connect using AJ command?
Method: After entering the concatenation command, you can enter "S" according to the prompt for partial concatenation, or you can use BO or BV to create closed primitives to achieve the purpose of creating concatenated primitives.
5. Sometimes all the data of the template is displayed as "0" in the comments of the brush?
Method: You can enter the command ST to change the text style, set the character height to 0 and click OK, and then try again after application.
6. What is the difference between automatic center mark and automatic mark in automatic mark?
Method: Automatic labeling of circle center will only label the coordinates of the center of the circle and the shape of the template, while automatic labeling will label the center of the irregular hole and the arc.
When you know all the functions in the program, how do you start to draw a complete set of molds? (Drawing process)
Method: The design process still needs to follow one's own ideas and drawing methods, but presscad is added to assist in the process of expression. Taking continuous mold design as an example, when we unfold the product, we can use "Calculate Usage Rate" and "Strip Arrangement" to assist in determining material utilization and layout.
When we don’t know which function is better to use, we need to have a deep understanding of the function of the command when we don’t know which function is better to use for the commonly used design functions "alien creation", "differential layering", and "drawing". as follows:
Alien creation
Its characteristic is that the setting is simple and clear, and it is fast to draw, but the holes produced on each layer only have differences in the gap, and the template for the holes to be produced cannot be customized, and the holes cannot be produced. It is most suitable for use in Make a simple straight punch with a special shape.
Alien Layered
It makes up for the shortcomings of "alien creation", but it sets a bit more. It needs to be selected multiple times to complete, and only the shape of the entry is produced. If there is no inner hole, you usually have to animate the auxiliary graphics you want by hand.
Into the child drawing
It is suitable for special-shaped punches that need to be drawn. In addition, complete the following settings before drawing:
(1) Select the required line cutting gap control method: such as output in annotation mode
(2) Select the correct type of mold: such as continuous mold
(3) Set the thickness of the template to be used
No plug-in can replace people to design independently, so don't think that you can learn a plug-in. This is just to make our drawing easier and faster, not a complete replacement. Being able to apply the software comprehensively to the design will greatly improve the drawing efficiency.
Mold design is easy to learn, the key is how to go in the right direction. Efforts are important, but they are in vain in the wrong direction. Think, it's all a problem! Do it, there will be results!
