Abstract
The invention discloses an extruding die for a honeycomb ceramic filter and relates to the field of honeycomb ceramic filters. The extruding die for the honeycomb ceramic filter comprises a die body, pug squeezing-in holes, a die sleeve, a gap, steps and meshes. The edges of the die are all provided with the steps, and the die body is engaged with the steps arranged on the inner round edge of the die sleeve through the steps. In addition, the gap is arranged in the engagement position of the die body and the steps. The multiple pug squeezing-in holes are evenly formed in the upper face of the die body. The multiple meshes are formed in the lower face of the die body, and the pug squeezing-in holes are communicated with the meshes formed in the lower face of the die body to form a whole. The extruding die for the honeycomb ceramic filter is reasonable in structure design, easy to operate, convenient to use, and capable of effectively controlling the thickness of the outer wall of the honeycomb ceramic filter; in addition, in the manufacturing process of the honeycomb ceramic filter, the extrusion deformation of the hole shapes of the filter by pug is avoided, and the standardization is reached.
Description
Technical field
The present invention relates to a kind of ceramic honeycomb filter extrusion die, belong to ceramic honeycomb filter technical field.
Background technology
Ceramic honeycomb filter is a kind of vitals diesel engines at present aiutage being used for filter black smoke; the toxic black smoke gas that diesel engine is discharged utilizes ceramic honeycomb filter to realize; ceramic honeycomb filter is made up of the honeycomb structure with the Porous next door dividing many runners; the next door in hole is attached with catalyst; next door and the catalyst of the dusty gas passing hole containing black smoke particle react; when reaching uniform temperature; particle can burned removing, because this reducing the pollution of diesel engine vent gas.In order to better reach filtration black smoke, require very high to the permeability in ceramic honeycomb filter hole and outer wall minimal thickness.Want to make the ceramic honeycomb filter meeting requirements at the higher level, depend on the mould of making; The mould of existing making ceramic honeycomb filter adopts plane mould, when adopting this mould to prepare ceramic honeycomb filter, outer wall thickness is uncontrollable, the filter outer wall prepared is thin, intensity is low, in preparation process, the pug at edge can squeeze distortion the hole shape of ceramic honeycomb filter simultaneously, have impact on the quality of product greatly.
Summary of the invention
For the problems referred to above, the technical problem to be solved in the present invention is to provide a kind of ceramic honeycomb filter extrusion die.
A kind of ceramic honeycomb filter extrusion die of the present invention, it comprises mould, pug clamp-ons hole, die sleeve, gap, step, mesh, the edge of mould is provided with step, and the step that mould is arranged by step and die sleeve internal circle is engaged mutually, and occlusion place is provided with gap, is evenly provided with several pug above mould and clamp-ons hole, below mould, be provided with several mesh, and pug clamp-ons the mesh UNICOM below hole and mould, form an entirety.
As preferably, in described mould, be staggeredly equipped with mould net wall, and this mould net wall is arranged according to the different mesh specification of ceramic honey comb product.
As preferably, described mould is fixed on above die sleeve, die sleeve is fixed in frame, the pug prepared is placed on above mould, extrudes downwards with hydraulic machinery, mould is a single piece, one side is arranged to pug and is clamp-oned hole, one side is arranged to mesh in addition, and pug clamp-ons hole and mesh is UNICOM, and intersection forms circular cone hole shape.
Beneficial effect of the present invention: its reasonable in design, simple to operate, easy to use, effectively can control the outer wall thickness of ceramic honeycomb filter, and make in the process of ceramic honeycomb filter, the hole shape of filter can not be squeezed distortion by slurry, reaches standardization.

Detailed description of the invention
As Figure 1-Figure 8, this detailed description of the invention is by the following technical solutions: it comprises mould 1, pug clamp-ons hole 2, die sleeve 3, gap 4, step 5, mesh 6, the edge of mould 1 is provided with step 5, and the step that mould 1 is arranged by step 5 and die sleeve 3 internal circle is engaged mutually, and occlusion place is provided with gap 4, evenly be provided with several pug above mould 1 and clamp-on hole 2, several mesh 6 is provided with below mould 1, and pug clamp-ons mesh 6 UNICOM below hole 2 and mould 1, forms an entirety.
Wherein, in described mould 1, be staggeredly equipped with mould net wall 1-1, and this mould net wall 1-1 is arranged according to the different mesh specification of ceramic honey comb product; Described mould 1 is fixed on above die sleeve 3, die sleeve 3 is fixed in frame, the pug prepared is placed on above mould 1, extrude downwards with hydraulic machinery, mould 1 is a single piece, and one side is arranged to pug and is clamp-oned hole 2, and one side is arranged to mesh 6 in addition, it is UNICOMs that pug clamp-ons hole 2 with mesh 6, and intersection forms circular cone hole shape.
The operation principle of the specific embodiment of the invention: pug is clamp-oned hole 2 by the pressure of hydraulic machinery from pug and entered mesh 6 extrusion molding downwards, because mould 1 edge is provided with the outer wall that gap 4 between step 5 and die sleeve 3 inwall creates ceramic honeycomb filter when pug extrusion molding, by the thickness regulating the size in gap 4 can control ceramic honeycomb filter product outer wall, ensure that the intensity of product, and outer wall is the pug extruded by step 5 to be formed, the mesh size and distortion etc. near outer wall can not be affected, ensure that product quality.
More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
