Bar, connecting rod is made with paste extrusion mould 22, arranges two rod hinge connection axles on mould flange 221, the axis of rod hinge connection axle is put down
Row makees crank, the axle center of crank driving wheel 212 is articulated with support member 24 in the direction of extrusion with crank driving wheel 212.Crank drives
Take turns 212 eccentric parts to be articulated with the jointed shaft of connecting rod, eccentric arm is equal to circular helix radius, and rocking bar is hingedly connected to frame
21st, on connecting rod.In Fig. 5, to describe crank driving wheel, the rocker device under clear support member 24, support member 24 is represented by dotted lines.
Crank driving wheel, rocking bar are between support member 24 and paste extrusion mould 22.Driving crank driving wheel is additionally provided with frame 21
212 motors 214 rotated.
Honeycomb support 1 does not have area except extrusion forming link, other links and the conventional manufacturing process of honeycomb support 1
Not.During the extrusion forming of honeycomb support 1, paste extrusion mould 22 and pressurizing unit 29 are in the plane perpendicular to extrusion direction
Relative motion inside be present.The uniform translation along the circumference perpendicular to the plane of the direction of extrusion of paste extrusion mould 22, and lotion squeezes
Go out mould 22 itself not rotate, the radius of a circle that paste extrusion mould 22 translates is equal to benchmark circular helix rounding cylinder radius
R, the angular velocity omega of mould translation are：ω=2π/（P/v）=2 π v/P, v is extrusion idiosome speed in formula, cylindrical screw on the basis of P
The helical pitch of line.When idiosome extrusion length is P, the time used is P/v, and within the period, paste extrusion mould 22 is around circle
All translational motions one week.The communicated band transmission of idiosome of extrusion, transmission line speeds are identical with the speed for extruding idiosome.
The radius of the circumference of the uniform translation of paste extrusion mould 22 in the present embodiment is smaller, the week of circumference uniform translation
Phase is long, and the linear velocity that paste extrusion mould 22 translates is very small, generally well below extrusion idiosome speed v, so, lotion
For extrusion die 22 circumferentially in translation motion, paste extrusion mould 22 is very small on cross shear influence caused by idiosome,
Help to ensure that idiosome extrusion forming quality.There is stronger rush for hole wall in view of the fluid in cylindrical screw-type fluid through-hole
Brush act on, particularly the larger particulate matter of quality because centrifugal force it is larger the reason for, stronger souring, hole are produced between hole wall
Wall surface should have stronger anti-wear performance.Because the lower surface of the idiosome of honeycomb support 1 is not plane, but cosine waveform
Curve form, certain pliability should be had by supporting the transmission belt surface of idiosome, to protect finished surface.
The honeycomb support 1 of the present invention is in processing, the lotion required for preparing first, then will prepare the cream completed
Body, by the extrusion molding of paste extrusion mould 22, while extrusion, passes through motor 214 in the presence of pressurizing unit 29
Driving crank driving wheel 212 rotates, and then drives paste extrusion mould 22 to move in a circle, and the honeycomb support 1 being extruded is logical
Cross conveyer belt 231 to be transported away, by the collective effect of conveyer belt 231 and paste extrusion mould 22, due to the spy of lotion in itself
The supporting role of property and conveyer belt 231 to lotion, will not deform, pass through paste extrusion in itself when lotion is placed on conveyer belt 231
The overall honeycomb support 1 that the motion of mould 22 makes to be extruded is in cylindrical helical, so as to realize the shaping of honeycomb support 1.
