Step ring rolling forming machine

Abstract

The invention discloses a stepped ring rolling forming machine, which includes an upper mold body (8) fitted on an upper template (23), a lower mold body (9) fitted on a lower template (19) and a core body ( 24) and the ejector mechanism, which includes the ejector rod (17), the ejector rod plate (14), the limit guide plate (16) and the ejector rod cylinder (13), and the lower template is provided with synchronous inward Or a slider (21) that moves outward, a return spring (11) is fixedly arranged between the slider and the lower mold body, and a movable block (10) that can pass through the lower mold body is fixedly connected to the slider ), the outer side of the slider is provided with a pressing block (22) that can touch or separate from the sliding block at the same time, and the pressing block can move up and down synchronously with the upper template. The invention not only has high manufacturing efficiency and low production cost; but also improves product quality, reduces labor intensity, saves working hours and a large amount of diesel oil, and the manufacturing efficiency is at least 6 times higher than the existing efficiency. more than doubled.

Description

technical field [0001] The invention relates to a pressure forming machine, in particular to a rolling forming machine for stepped ring packing. Background technique [0002] The step ring is the most widely used ceramic packing in the internals of industrial tower equipment. Since the inner cavity of the step ring has a cross structure staggered up and down, the step ring has four windows with two staggered crosses. Due to the limitation of the step ring structure, the manufacture of the step ring is currently mostly manual or semi-mechanical combination. The first part and the lower cross part are manufactured by hand or machine respectively, and then the parts are bonded and assembled by hand, and then fired at high temperature to form a whole. The existing manufacturing methods of stepped rings have the following problems: First, in the manufacturing process, due to the rigidity of the mold, the compaction force is small, so the compactness is not high, and the product ...

AI Technical Summary

Problems solved by technology

The existing manufacturing methods of stepped rings have the following problems: First, in the manufacturing process, due to the rigidity of the mold, the compaction force is small, so the compactness is not high, and the product is easily deformed during high-temperature firing, which reduces the quality of the stepped ring product; The second is that the production efficiency is low, the man-hours are many, and the production cost is high; moreover, in the process of mold cleaning and demoulding, a large amount of diesel oil needs to be consumed, etc.
