Embodiment Construction

[0030] figure 1 An apparatus for rolling a honeycomb body according to the invention is shown. The equipment includes a frame, a transmission system, and a forming die 1 and a tightening die 6 for roll-forming the honeycomb body.

[0031] figure 2 and 3 A detail of an apparatus according to the invention for rolling a honeycomb body is shown. Forming mold 1 comprises four parting molds (see image 3 ), these four parts can be opened and closed. For example, the four parting molds are supported on the frame like four jaws of a four-jaw chuck. Preferably, each parting mold can slide radially in its own slideway. They are biased towards opening by elastic members. Of course, it is also feasible to arrange the parting molds in other known ways.

[0032] Depend on image 3 It can be seen that in the opened state of the forming die 1, there is a gap A between the four parting dies, through which the corrugated belt and flat belt assembly 3 to be rolled can be sent into the...

Abstract

A system for manufacturing a honeycomb body is provided. Said system comprises: a forming mold (1) with a plurality of sub-molds, which are movable so that they can be opened and closed; a tightening mold (6) for tightening said forming mold (1); rolling pin(s) (2), which can be inserted into and pulled out of the inner volume of said forming mold (1) and can rotate around a rotation axis; wherein said tightening mold (6) has a shape that cooperates with the shape of said forming mold (1), so that an action of said tightening mold (6) causes tightening of said forming mold (1).

Description

technical field [0001] The present invention relates to a device and a method for rolling a honeycomb body, more particularly, to a device and a method for rolling an S-shaped metal honeycomb body. Background technique [0002] Honeycomb bodies are used in many fields, for example as filters. Honeycomb bodies are commonly used catalyst supports in the field of exhaust gas purification of motor vehicles and engines. The honeycomb body has a particularly large contact surface area, low air resistance, and excellent mechanical properties and catalytic engineering properties. In recent years, the S-shaped metal honeycomb body has attracted special attention. [0003] The metal honeycomb body is generally rolled from metal foil, and the honeycomb structure needs to be continuously tightened during the rolling process so that the honeycomb body has a definite internal channel structure. The manufacturing precision of the honeycomb affects its service life as well as other prope...
