Turnup side riveting die of automobile clutch cover assembly

Abstract

The invention discloses a turnup side riveting die of a CP type automobile clutch cover assembly. The riveting die comprises an upper die holder and a lower die holder, the upper die holder and the lower die holder are arranged in a guide mode through guide sleeves and guide columns, the guide sleeves and the guide columns are cooperated, an upper bearing plate is fixedly arranged on the lower surface of the upper die holder, a base plate is fixedly arranged on the upper surface of the lower die holder, a cylindrical shell is fixedly arranged at the lower end of the upper bearing plate, a reset ring is arranged at the lower end of the shell, guide wheels are arranged at the lower end of the reset ring, the reset ring is provided with a conical cavity, a core shaft is fixedly arranged on the upper bearing plate, and the core shaft is sleeved with a middle guide plate and a middle core base in a sliding mode. According to the die, positioning is reliable, in order to reduce the riveting clearance, cover tongue piece bending and flattening are required to be completed in a pair of dies when a diaphragm spring is in the flattening state, and it is ensured that the compression size of an elastic supporting ring is in the specified size tolerance, and a cover, the diaphragm spring and the elastic supporting ring do not abnormally deform.

Description

technical field [0001] The invention relates to a CP type automobile clutch cover assembly turn-up riveting die. Background technique [0002] In order to meet the technical requirements of riveting and riveting, a foreign company adopted a double riveting process for a DST-type clutch cover assembly with a similar structure, adding one more process and one piece of equipment, which affected production efficiency. There are also some small companies that use the arc-shaped extrusion deformation of the mold to complete the riveting at one time. Due to the irregular deformation, the support is circular and oval, and the product quality cannot be guaranteed. Contents of the invention [0003] The purpose of the present invention is to provide a CP type automobile clutch cover assembly turn-over riveting die, the die requires reliable positioning, in order to reduce the riveting gap, it is required to complete the cover tongue in a pair of dies when the diaphragm spring is i...
