Abstract
The inventive belt pulley comprises bull and pony wheels integral formed by spinning of flat cold-rolled sheets. The process of manufacturing the belt pulley consists in: blanking; multistretching; shaping; spinning; punching and surfacing. The blanking is stretched into the semi-finished products for the two-stage coaxial multi-wedge pulley on the oil press by the multistretching and the times of multistretching can depend on the product conditions. The shaped and edged semi-finished pulley once-through complete the following process: spinning the big end and then spinning the small end by the spinning process.
Description
Technical field
The present invention relates to a kind of by the integrated two-stage coaxle multi-wedge type pulley of cold-reduced sheet and processing technology and equipment.The present invention is applicable to all belt pulley gearings, is particularly useful for automotive industry.
Background technique
The production of conventional belt wheel is to be that blank is through the machining moulding with cast iron, cast copper, cast aluminium and alloy, product is not only wasted resource, processing cost exceeds 30%-50% than extruded product, waste of material is more than 30%, and work under bad environment in the casting process simultaneously is unfavorable for environmental protection and wastes energy, cast main base in addition because of pore is arranged, it is inhomogeneous to cause base material ground, and the balance quality of belt pulley is poor, also need do Balance Treatment after the belt pulley processing.Is that blank is compared through the belt pulley of machining moulding with tradition with cast iron, cast copper, cast aluminium and alloy, be a kind of be raw material with the quality steel plate through the belt pulley of punching stretch extrusion modling repeatedly.Thickness difference minimum (generally in 0.005mm) in the cold working belt pulley unit blank area, through squeeze, quality is more even behind the spinning, so has fabulous quiet, dynamic balance performance, does not need to remake Balance Treatment fully.The good mechanical property of steel plate, intensity is big, has higher surface finishment and surface hardness by extruding trailing wheel rooved face, and the equivalent diameter belt pulley, adopt steel plate processing back volume weight to reduce greatly, reduced startup and braking moment. reached energy-saving effect.But the existing steel plate that adopts is generally single-stage by the belt pulley of cold working manufacturing, and two-stage coaxle multi-wedge type pulley is to be welded into one by the big belt pulley of the different machine shaping respectively of diameter and small belt pulley point, is the split shaping structure.And two-stage coaxle multi-wedge type pulley also will satisfy the requirement of two-wheeled concentricity except that two single-wheels are identical with the requirement of single-stage precision index.The two-stage coaxle multi-wedge type pulley of this minute body structure exists fastness poor, and it is big to beat, and two inter-stage coaxalitys are difficult to guarantee overall appearance (there is soldered on the surface) not attractive in appearance, shortcomings such as the perishable internal material of surface treatment.And, existing spinning machine is two, three station spinning machines, processing stations is few, processing secondary coaxle multi-wedge type pulley need repeatedly be changed spinning wheel, repeatedly adjustment level is revolved the position height, can not a clamping machine shaping, two inter-stage coaxalitys are difficult to guarantee, thereby the processing of incompatibility two-stage coaxle multi-wedge type pulley.
Summary of the invention
What technical problem to be solved by this invention provided a kind of one spinning shaping structure is two-stage coaxle multi-wedge type pulley and the processing technology and the spinning machine of base material with flat cold-rolled sheet (steel plate).The two-stage coaxle multi-wedge type pulley of this structure can overcome the above-mentioned defective of the similar belt pulley existence of existing split machine shaping, and easy processing, the precision height, and homogeneity is good, and is in light weight.The spinning function that is provided is carried out two-stage wedge groove spinning in succession behind disposable clamping, realize finishing second level wedge groove spinning under the constant situation in location.
Two-stage coaxle multi-wedge type pulley provided by the present invention comprises bull wheel and steamboat, and described bull wheel and steamboat are one-body molded by flat cold-rolled sheet spinning.
Said structure is comprised by the processing technology of the integrated two-stage coaxle multi-wedge type pulley of flat cold-rolled sheet: blanking, multiple tracks stretching, shaping, spinning, punching, surface treatment; It is that blanking is drawn into the two-stage coaxle multi-wedge type pulley semi-finished product on oil hydraulic press that multiple tracks stretches, and the number of times that multiple tracks stretches is decided on the product situation; Spinning be with through the semi-finished product belt pulley of shaping, side cut on a spinning machine once clamping finish following operation successively: the big end of spinning, spinning small end.
The further technological scheme of the present invention provides a kind of spinning machine of implementing spinning in the above-mentioned processing technology that adapts to, and this spinning machine comprises flanging cylinder component, pull bar, underdrive mechanism, counterdie, flanging mould, flanging worktable, patrix, lifting spinning wheel cylinder component, post rod mechanism, middle table assembly, master cylinder assembly, guide rod; Described flanging worktable has individual sliding sleeve for four jiaos, but vertical lift slides on 4 guide rods, and the flanging worktable is connected with flanging cylinder component oil cylinder by 2 pull bars, and oil cylinder piston and support are fixed, and the flanging mould is installed on the flanging worktable; Described lifting spinning wheel cylinder component includes the identical cover of three on the spinning machine worktable spinning wheel assembly that is arranged on of structure, lifting spinning wheel assembly comprises the spinning wheel seat, moves horizontally oil cylinder, moves horizontally frame, vertical lift oil cylinder, vertical movement frame, spinning wheel and spinning axle, move horizontally oil cylinder and the spinning wheel seat is rigidly connected, the piston rod that moves horizontally oil cylinder is with to move horizontally frame hinged, and vertical lift oil cylinder and vertical movement frame are rigidly connected and to move horizontally frame hinged.
The invention has the beneficial effects as follows: 1, the two-stage coaxle multi-wedge type pulley of one machine shaping with compare with the two-stage coaxle multi-wedge type pulley of small belt pulley spot welding all-in-one-piece split processing by the big belt pulley of the different machine shaping respectively of diameter have fastness good, beat little, two inter-stage coaxalitys are good, surface integral body, appearance looks elegant, surface treatment can not corroded advantages such as internal material; 2, processing technology smoothness, compactness; 3, spinning can a clamping be finished two-wheeled spinning, has overcome that existing spinning machine need more mold exchange and clamping produce the very big shortcoming of coaxiality error between two-wheeled by secondary.
Below in conjunction with drawings and Examples technology contents of the present invention is described further.
