Device for making S-shaped metal honeycomb carriers

Abstract

The invention discloses a device for making S-shaped metal honeycomb carriers. The device for making the S-shaped metal honeycomb carriers comprises an inner disc; an outer disc is arranged on the outer edge of the inner disc; an axis hole and a fixed section are arranged on the inner disc; a fixed column is arranged in the axis hole; one end of the fixed section is connected with a pattern die through a spring device; the outer end of the pattern die is connected with a driving rod; a bearing is arranged at the outer end of the driving rod; an arc-shaped raised guide rail is arranged on the outer disc; the bearing extends into the arc-shaped raised guide rail; and the section of the fixed column and the section of the closed pattern die are circular or elliptic, and a rotation driving device is arranged on the outer disc. The structure of the conventional device is greatly simplified; the device has the advantages of cost saving, convenience in installation, capability of producing S-shaped metal honeycomb carriers of multiple specifications and simplicity in maintenance; and in the rolling process, the production efficiency of the device can be optimized, and the production cost can be reduced.

Description

technical field [0001] The invention relates to a manufacturing device for an S-shaped metal honeycomb carrier used for an exhaust catalytic converter of a motor vehicle engine. Background technique [0002] In order to meet the requirements of increasingly stringent emission regulations, higher technical requirements are also put forward for the metal honeycomb carrier used in the exhaust gas purification catalytic converter. The metal honeycomb carrier produced in my country basically adopts a spiral structure. Due to its poor thermal creep resistance, thermal deformation resistance and mechanical durability, it has been largely replaced by S-shaped metal honeycomb carriers abroad. At present, the S-shaped metal honeycomb carrier has become the basic structure of the metal honeycomb carrier because of its reliable durability and good turbulence formation, but the processing of the S-shaped metal honeycomb carrier is relatively difficult.

AI Technical Summary

Problems solved by technology

At present, the S-type metal honeycomb carrier has become the basic structure of the metal honeycomb carrier due to its reliable durability and good turbulence formation, but the processing of the S-type metal honeycomb carrier is relatively difficult.

[0003] Patent 200710148010.X discloses a manufacturing device of S-shaped metal honeycomb. The device adopts two groups that can be closed section by section to form a mold that has the same shape as the finished honeycomb body. However, the forming section of the device consists of at least three sections. Pin hinges are used between each section to form a chain structure. The production process of the equipment is relatively complicated, and a single machine cannot produce multi-standard S-shaped metal honeycomb carriers.

[0004] The S-shaped metal honeycomb rolling device disclosed in the patent CN1187784A adopts at least two arc-shaped mold segments to rotate around the axis respectively, and the fixed column in the central hole rotates around the opposite direction; because the fixed column in the central hole is rotating, and the two sides Forcibly closing the arc-shaped die section into a mold with a specified size will cause the tooth shape of the honeycomb inner core to be forcibly deformed and become a waste product; if the inner core material with a low forming tooth is used, the inner core will be loose and it will also become a waste product. Therefore, it is difficult for this device to use domestic core materials, and at the same time, a single machine cannot realize fast switching to produce multi-standard S-shaped metal honeycomb carriers
