Description

Technical Field

[0001] The utility model specifically relates to the technical field of rapid die change, and specifically is a rapid die change device for a forming die. Background Art

[0002] The rapid die change device plays an important role in modern manufacturing, especially in production scenarios where the die needs to be frequently changed; the rapid die change device greatly shortens the die change time: the traditional die change method may take several hours, while the rapid die change device can greatly compress this time, improving the utilization rate of equipment and production efficiency; it improves production flexibility: enabling enterprises to more quickly respond to changes in market demand and flexibly adjust the types and specifications of products produced; it reduces the manpower requirement: reducing the labor intensity of operators and the manpower input required during the die change process;

[0003] Currently, when the traditional forming die is in use, it is integrally arranged with the processing equipment, which effectively guarantees the processing quality and working efficiency during the processing. However, in current production, it is necessary to replace the forming die according to production needs to facilitate the production and processing of different products. However, since most current dies cannot be disassembled, or when disassembling and replacing, it takes a lot of time, which will result in low working efficiency.

[0004] After retrieval, Chinese Patent Publication No. CN202110433261.2 discloses a rapid die change device for a forging die; it includes a fixed die base and a sliding die base. The opposite surfaces of the sliding die base and the fixed die base are working surfaces, and the sliding direction of the sliding die base is perpendicular to the working surface. A fixed die is installed on the working surface of the fixed die base, and a sliding die is installed on the working surface of the sliding die base. It also includes two groups of positioning components respectively installed on the sliding die base and the fixed die base. The positioning component includes a positioning disk, and the positioning disk is provided with a positioning groove for installing the fixed die or the sliding die. The positioning component also includes a positioning member. The positioning member includes a slider slidably connected to the circumference of the positioning disk. The slider includes a sliding portion and a connecting portion. The connecting portion is used to connect with the positioning disk, and an arc-shaped groove for clamping the fixed die or the sliding die is provided on the side of the connecting portion facing the positioning groove;

[0005] Although the structure in the above patent can achieve the replacement effect, when replacing the sliding die, since the bottom of the sliding die is suspended, a supporting device needs to be added during replacement. When the sliding die is disassembled and contacts the supporting device, the supporting device may affect the surface of the sliding die, and the integrity of the surface of the sliding die cannot be effectively guaranteed; moreover, the structure in the above patent cannot effectively achieve the effect of simultaneously disassembling the fixed die and the sliding die, which will result in a longer replacement time and affect the working efficiency of the equipment.
