Problems solved by technology

The disadvantage of single-process production is that the production process of the bottom plate is long, the occupied equipment and operators are many, and the production efficiency is low.
After repeated positioning of multiple processes, the dimensional accuracy of the produced bottom plate is difficult to meet the requirements of the design drawings; the forming of the hole is processed by two processes of punching (pre) hole and reaming with a drill bit. The surface roughness and the position and size of the hole are not up to the design requirements.

Embodiment 1

[0025] Example 1. Such as Figure 1-Figure 11 As shown, the precision porous base plate for sealing is composed of 8 holes, bosses and ribs. The stamping method of the base plate is: the strip material is fed into the mold according to the step distance through the automatic feeder, and the press (punch) Next, complete the following steps: step 1 punching, step 2 guiding, step 3 guiding, step 4 punching waste, step 5 empty step, step 6 empty step, step 7 punching waste, step 8 Step empty step, step 9 punching pre-hole, step 10 punching pre-hole, step 11 empty step, step 12 extrusion platform, step 13 empty step, step 14 extrusion rib, step 15 empty step, step 16 Step empty step, step 17 fine punching, step 18 empty step, step 19 blanking, while blanking step 19, steps 1 to 18 are also carried out simultaneously, so that the press (punch) moves At one time, the stamping and forming of a bottom plate can be completed. Steps 1 to 19 are carried out simultaneously in one pair o...

Abstract

The invention provides a method for stamping a precisely porous bottom plate for sealing. In the method, strips are acted by a press, so that an upper mold and a lower mold of a mold move mutually under the action of the strips, and when the strips are acted by the press, the bottom plate is stamped by the following steps of: 1, punching; 2, guiding; 3, guiding; 4, punching scraps; 5, idling; 6, idling; 7, punching scraps; 8, idling; 9, pre-punching; 10, pre-punching; 11, idling; 12, extruding; 13, idling; 14, extruding ribs; 15, idling; 16, idling; 17, performing fine punching; 18, idling; and 19, blanking. The method has the characteristics of high production efficiency, high dimensional accuracy, high quality consistency and the like, and the requirements of positional precision and surface roughness of bores on the bottom plate can be effectively met.

Description

technical field [0001] The invention relates to a stamping forming method, in particular to a stamping forming method of a precision porous bottom plate for sealing. Background technique [0002] The precision porous bottom plate for sealing is an important part of the sealing component. The bottom plate has an inner hole for sealing with the lead-out end and a shape (boss, ring rib, etc.) for sealing with the outer shell. In order to improve the sealing performance of the product, the bottom plate High requirements are put forward for the dimensional accuracy and surface roughness of the inner hole and shape (boss, ring rib). The existing precision porous bottom plate for sealing is a single-process production, and the processing of the bottom plate is mainly completed through processes such as punching (pre) hole blanking, extrusion, bead extrusion, edge trimming, and hole expansion. The disadvantage of single-process production is that the production process of the botto...
