Description

A die used in the flanging and side punching process of automobile body parts

Technical field:

The utility model relates to the field of manufacturing process equipment, in particular to a mold used in the flanging side punching process of automobile body parts.

Background technique:

In the development and manufacturing process of automobile body parts, the mold development of body parts occupies a very important proportion. The mold development of body parts is not only expensive, but also has a relatively long cycle. The quality of body parts plays a key role in the quality of the body. At present, the number of mold sets for the development of a complete vehicle in the field of automobile body development is basically around 1,000 sets. The huge number of mold sets directly leads to an increase in the number of presses required, and a corresponding increase in production costs. The most direct manifestation is mold development. The cost increases, and the increase in the number of mold sets leads to a series of problems such as increased debugging workload and increased mold management work. Side flanging and side punching are very common mechanisms in mold structures, but they are usually used first. One set of molds is used for side flanging, and another set of molds is used for side punching. Two sets of molds are required to realize flanging and rear side punching. This product has a hole on the side wall of the part, and the precision requirement is relatively high, and the upward and downward flanging must be realized at the same time in this process. According to the conventional thinking, a set of molds is required to complete the upward and downward flanging first, and then use another set of molds to punch holes separately. However, limited by the customer's production line and labor costs, if you add a set of molds, you need to increase the cost of a set of molds, press machine usage fees and depreciation costs, stamping workers' wages, etc.
