Description
Technical field
The present invention relates to a kind of be used for engine emission catalytic converter metal beehive rolling device.
Background technique
Along with the increasingly stringent of Abgasgesetz, exhaust catalytic converter with metal beehive higher technical requirements has been proposed also.Metallic carrier is generally formed (referring to Fig. 1 and Fig. 2) by cellular inner core 9 with shell 10.The metallic carrier that China produces at present is screw type cellular structure (referring to Fig. 1) substantially, this is the product of the external seventies, because its heat resistanceheat resistant creep and relatively poor, the poor durability of thermal deformation resistant ability, replaced by the cellular structure (referring to Fig. 2) of S type in a large number abroad.S type structure forms action of turbulent flow preferably and becomes metallic carrier basic structure with its reliable endurance quality.
Patent CN1078101C discloses a kind of rolling device and method of S type metal beehive.Place one to turn around device honeycomb inner core lamination (being that metal corrugated plate and metal plain film are superimposed), then by at least two arc mould sections, rotate around the axis respectively, and it turns to and turn around the device switched in opposite, closed and form one with the identical pattern of making of honeycomb ceramics profile.
The deficiency of these apparatus and method is that the rolling requirement of material of internal chip is very high.Chip is to adopt the siderochrome aluminium material in the honeycomb, and thickness is 0.02-0.1, makes corrugated plate and plain film respectively, is cut into the length of regulation then, and the alternate stack of corrugated plate and plain film rolls and forms.Homemade siderochrome aluminium material is compared with external siderochrome aluminium material, and its material component is identical can accomplish, but rolling level differs greatly.Homemade siderochrome aluminium material is less owing to manufacturer's scale, rolling, the annealing device condition restriction of employing, and thickness deviation that it is rolling and material hardness, conformity is far away from imported materials.Homemade inner core material is because the difference of rolling thickness, hardness, and its difference can be exaggerated behind rolling corrugated plate, and often two thickness differs the inner core material less than 0.01, and tooth depth differs 0.1 unexpectedly after being rolled into corrugated plate, and difference has been amplified 10 times.But homemade inner core material low price, less than 1/3 of materials overseas, and inner core material accounts for very big proportion in the metallic carrier manufacture cost.Because homemade material, thickness and hardness discreteness are bigger, thicker or harder inner core material sheet is after being rolled into corrugated plate, the tooth depth that the profile of tooth height is just relatively thinner or softer inner core material rolls into, although both are more or less the same, only several or surpass ten, under the situation of mass production, be difficult to detect one by one.And cellular inner core normally is made up of thousands of even hundreds thousand of holes (being profile of tooth), and accumulative total differs just big.
Said apparatus and method, after the plain film of equal length and the corrugated plate stack, if adopt the inner core material (too thick or too hard) of moulding tooth depth as material, because middle winding device is changeing, and outside two arc moulds section is closed by force and form the pattern of given size, causes honeycomb inner core profile of tooth to be out of shape by force.Become waste product; If adopt the low inner core material (too thin or too soft as material) of formed tooth, the honeycomb inner core is looser, has also become waste product.
Therefore said apparatus and method are difficult to use homemade inner core material.
Summary of the invention
The purpose of this invention is to provide a kind of manufacturing installation that is applicable to the S type metal beehive of homemade siderochrome aluminum slice, to solve prior art to rolling requirement height of the siderochrome aluminum slice of making metal beehive and the high problem of cost of production.
Technological scheme of the present invention is: comprise that fixing column 1 and two groups can the closed piecemeal mutually shaped segments 5 that forms pattern, be provided with two coaxial fixing rods 4 on the top of fixing column 1.Every group of described shaped segment 5 formed by three sections at least, be hinged to chain structure with pin between every section, this shaped segment 5 can be deformed into the bigger curve of curvature gradually by straight line or the less curve of curvature, two groups of described shaped segment 5 closed cross sections that form are circle, long-round-shape or oval-shaped pattern, and the sectional shape of described fixing column 1 is corresponding with the shape of this pattern; In the outside of described shaped segment 5 the pattern locking device is housed, is bent to closed pattern gradually with each section that drives shaped segment 5.
One folded metal corrugated plate and the flat plate body that superposes is positioned on the fixing rod of the static device that is used for fixing metallic laminations that a pattern opens, this fixing rod can be two metallic rod at a distance of certain distance, also can be a device with fork configuration.Be fixed with the inner disc of forming station then and be fixed with the outer dish of arc groove guide rail simultaneously around equidirectional rotation.The rotational velocity of outer dish is omited the rotational velocity faster than inner disc.The driveshaft outboard bearing enters in the groove of arc groove guide rail one by one, because the distance between groove and the fixing column configures, forces the closed piecemeal and locking of each segmental arc of pattern.Metallic laminations is in the closure piecemeal of pattern simultaneously, and the bending distortion forms and the identical S type honeycomb inner core of closed back pattern internal diameter.This metal beehive inner core has two turning points, and the siderochrome aluminum slice of corrugated plate and flat plate stack is the radial pattern distribution around these two turning points and forms S type metal beehive inner core.
Owing to adopt technique scheme; it rolls in the process; metallic laminations fixing column (being S type center) is static; both made the inner core tablet a little slightly long, in rotation process, the pattern of segmentation closure can be stretching the corrugation profile of tooth; make the stretching plain film that becomes of redundance profile of tooth; be fitted in honeycomb inner core periphery, so and S type center profile of tooth always transfixion can not be out of shape, improved Forming Quality and yield rate.
The fixing column of the metallic rod of chip or fork configuration is motionless in the clamping of the present invention, relies on the rotation of arc mould section and closure piecemeal to finish the process of rolling.The benefit of doing like this is, interior chip is clamped in metallic rod or fork configuration partly is subjected to less active force, can not resemble the prior art because its metallic rod or fork configuration act on the return portion of honeycomb inner core fully at spinning force, cause the corrugated plate of return portion to be evened up to make the duct distortion or stop up.
