Abstract
The invention discloses an insulating layer knurling manufacturing technique of insulating wall for silencer, motor and vehicle body, which comprises the following steps: (1) plugging aluminium board or aluminium film according to the size of element appearance standard; (2) making the aluminium board or aluminium film rotate and roll to form refracting face through knurling manufacturing device; (3) punching and ripping the aluminium board or aluminium film; (4) shaping the aluminium board or aluminium film through punching equipment. The invention can fit for rolling and moulding of different thicknesses, different layers of aluminium board or aluminium film, which improves the manufacturing efficiency greatly and saves utility of raw material.
Description
Technical field
The present invention relates to a kind of auto parts machinery processing technology, especially relate to a kind of technique for processing knurl of thermal shield and heat insulation course.
Background technology
At present automobile industry is mainly the aluminium sheet of different-thickness or the aluminium film of the different numbers of plies for the set thermal insulation board thermal insulation layer material therefor in silencer, engine and vehicle body position, it mainly utilizes the reflective insulation principle of heat shielding, cut off the transmission of heat, it also has the effect of certain part every noise simultaneously.After aluminium sheet, all employing amounts of aluminium film type are cut, form each plane of refraction heat dissipating layer by each operation moulding coverage mode of mould, each refraction point face all adopts complicated processing technology to form sags and crests face up and down, forms by the hydraulic test compacting, and the production work efficiency is not high.Aluminium sheet, aluminium film to different product, the different numbers of plies need different moulds to suppress, and the Mold Making cost is higher.Aluminium sheet, aluminium film add man-hour because of being subjected to former prefabricated profile factor, shrink unbalance stress during compacting, easily produce the plane of refraction crackle, influence radiating effect and durability.
Summary of the invention
The purpose of this invention is to provide a kind of technique for processing knurl of thermal shield and heat insulation course, this processing technology can the moulding of disposable many planes of refraction annular knurl, and can adapt to aluminium sheet, the aluminium film calendering forming of different-thickness, the different numbers of plies.
Technical problem to be solved by this invention is achieved by the following technical solution: it may further comprise the steps: (1) presses aluminium sheet or aluminium film the dimensional requirement blowing of part profile specification; (2) aluminium sheet to be formed behind the blowing or aluminium film are passed through the annular knurl processing unit (plant), warp annular knurl roll shaft is up and down turned round to cycle rotation spreading formation plane of refraction; (3) aluminium sheet to be formed or the aluminium film that will form plane of refraction passes through pressing equipment punching cutting edge; (4) aluminium sheet after the punching cutting edge or aluminium film are passed through pressing equipment compression moulding.
The invention has the beneficial effects as follows:
1,1/3 of one pair of former compacting tool set value of the employed plant equipment less than of whole annular knurl technology, but can be applicable to all products.2, by adjusting knurling roller distance between axles up and down, can adapt to the aluminium sheet or the aluminium film calendering forming of different-thickness, the different numbers of plies.3, form consistent wide cut by part specifications during feeding, stressedly evenly can not produce the spreading crack, reduce the processing link waste.4, disposable many planes of refraction annular knurl moulding, production efficiency improves greatly, has saved raw-material utilization rate simultaneously.
Description of drawings
The present invention is further illustrated below in conjunction with accompanying drawing
Accompanying drawing is depicted as the annular knurl processing unit (plant) of the present invention structural representation of annular knurl roll shaft up and down.
The specific embodiment
Technique for processing knurl of thermal shield and heat insulation course may further comprise the steps: (1) presses aluminium sheet or aluminium film the dimensional requirement blowing of part profile specification; (2) aluminium sheet to be formed behind the blowing or aluminium film are passed through the annular knurl processing unit (plant), warp annular knurl roll shaft is up and down turned round to cycle rotation spreading formation plane of refraction; (3) aluminium sheet to be formed or the aluminium film that will form plane of refraction passes through pressing equipment punching cutting edge; (4) aluminium sheet after the punching cutting edge or aluminium film are passed through pressing equipment compression moulding.The aluminium film of the aluminium sheet of different-thickness, the different numbers of plies can pass through the moulding of the disposable many planes of refraction annular knurl of annular knurl processing unit (plant), can bond with adhesive between the aluminium film of multilayer number.By the accompanying drawing annular knurl processing unit (plant) structure of annular knurl roll shaft up and down as can be known, last annular knurl roll shaft 1, annular knurl roll shaft 2 surfaces are equipped with convex structure 3 down, and convex structure 3 height are 0.3-0.8mm, each convex structure formation plane of refraction.The annular knurl processing unit (plant) is by the motor-driven gear, drive transmission mechanism by gear, transmission mechanism drives the roll shaft of annular knurl up and down 1,2 that has been processed into plane of refraction and turns round to cycle rotation, aluminium sheet to be formed, aluminium film are delivered to up and down 1,2 on annular knurl roll shaft, be rolled into the plane of refraction finished product through roll shaft by the kind of drive.Adjust the spacing of annular knurl roll shaft 1,2 up and down, can adapt to the aluminium sheet or the aluminium film calendering forming of different-thickness, the different numbers of plies.
Embodiment: (1) presses the aluminium sheet of 0.5mm the dimensional requirement blowing of part profile specification; (2) aluminium sheet to be formed behind the blowing is passed through the annular knurl processing unit (plant), warp annular knurl roll shaft is up and down turned round to cycle rotation spreading formation plane of refraction; (3) will form the aluminium sheet to be formed of plane of refraction by pressing equipment punching cutting edge; (4) aluminium sheet after the punching cutting edge is passed through pressing equipment compression moulding.
Claims (1)
1. technique for processing knurl of thermal shield and heat insulation course is characterized in that this technology may further comprise the steps:
(1) aluminium sheet or aluminium film are pressed the dimensional requirement blowing of part profile specification;
(2) aluminium sheet to be formed behind the blowing or aluminium film are passed through the annular knurl processing unit (plant), warp annular knurl roll shaft is up and down turned round to cycle rotation spreading formation plane of refraction;
(3) aluminium sheet to be formed or the aluminium film that will form plane of refraction passes through pressing equipment punching cutting edge;
(4) aluminium sheet after the punching cutting edge or aluminium film are passed through pressing equipment compression moulding.
