Embodiment Construction

[0024] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0025] refer to figure 1 , figure 2 , a stamping part 100 for processing a corrugated sheet, the stamping part 100 has a corrugated stamping surface 100a, the corrugated stamping surface 100a is suitable for contacting the metal sheet to be processed and exerting force on the metal sheet, so as to stamp the metal sheet to form a wave The processed corrugated sheet has a corrugated surface matching the corrugated punching surface 100a. That is to say, for a given shape of the corrugated stamping surface 100a, only corrugated sheets with the same corrugated surface shape can be processed.

[0026] combined reference image 3 , Figure 6 , in this embodiment, the stamping part 100 includes a plurality of stamping parts 10, and each stamp...

Abstract

The invention discloses a stamping die and a stamping piece used for machining a corrugated sheet. The stamping piece is provided with a corrugated stamping surface, and comprises a plurality of stamping parts which are detachably connected, wherein each stamping part is provided with a sub-stamping surface, the plurality of stamping parts are suitable for being fixedly connected to enable the plurality of sub-stamping surfaces to form the corrugated stamping surface. By designing the different stamping parts, the different stamping parts are enabled to have the sub-stamping surfaces with different shapes, moreover, the different stamping parts are combined so that the corrugated stamping surfaces with different shapes can be formed; by utilizing the corrugated stamping surfaces with the different shapes to stamp metal sheets so that the corrugated sheets with different corrugated surface shapes can be machined; and according to the technical scheme, the overall shape of the stamping piece does not need to be changed, and the stamping piece does not need to be manufactured again so that a lot of time and cost can be saved.

Description

technical field [0001] The invention relates to the technical field of mechanical stamping dies, in particular to a stamping die and stamping parts for processing corrugated sheets. Background technique [0002] The wave plate has a wave surface and is usually arranged between two friction plates of the clutch disc. The friction plates of the clutch disc and the clutch cover transmit torque through frictional engagement. During the engagement process of the clutch disc and the clutch cover, the wave plate can produce elastic deformation, so that the engagement process can be smoother. Among them, the wave plates required by different types of clutches are not the same, and the shapes of the wave surfaces in the wave plates are also different. [0003] The corrugated sheet is usually formed by stamping with a stamping die. The stamping die has a stamping surface that matches the corrugated surface. The shape of the stamping surface determines the specific shape of the corrug...
