Abstract
The utility model relates to a multi-wedge flange thickening spinning belt pulley for an automobile engine water pump, which solves the problems of the prior flange single thickening spinning belt pulley that the thickness of the thickening part is not uniform and nonuniformity stress is easily generated and the groove shape material is not fully filled, resulting into groove shape angle deformation and relative high reject rate. The flange thickening spinning belt pulley comprises a flange and a spoke, wherein the thickness of the spoke is 2.25-2.5mm and the thickness of the flange is 3.2-3.5mm and a V shaped groove is formed by spinning the flange plane circle wall. The beneficial effects are that: when the belt pulley has relative high requirement for the flange thickness, the relative thin blank is processed and the flange is independently thickened and the multi-wedge flange thickening spinning belt pulley product is formed by spinning the thickened plane circle wall and the thickness is uniform, the stress is uniform and the material is saved, the whole weight of the belt pulley is reduced and the underfilling phenomena of the groove filler is solved and the yield of the product process is increased.
Description
Technical field
The utility model belongs to the spinning belt pulley technical field, and particularly a kind of a kind of motor car engine water pump of making by spinning with steel plate thickens spinning belt pulley with many wedges wheel rim.
Background technique
Belt pulley is a kind of important mechanical transmission component.Traditional belt pulley is to adopt casting technique to make the belt pulley blank, is processed to form belt pulley through surface cut again, and its shortcoming is a waste material, and machining accuracy and surperficial mechanical strength are lower.In recent years, the belt pulley rotary pressure technology has obtained using widely, the belt pulley that adopts rotary pressure technology to make, and light in structure, material is economized, and surperficial mechanical strength is higher, and the dimensional accuracy height.Usually, adopt rotary pressure technology processing belt pulley, be by waiting Plate Steel one rotary press modelling on spinning machine, the wheel rim that is spun to is consistent with the thickness of spoke, under the situation that belt pulley has higher requirements to flange thickness, in order to guarantee rim of pulley thickness, can only adopt thicker blank to process, this has just increased the overall weight of belt pulley, has also increased belt pulley rotary inertia when work, adds the consumption of macro-energy.
The applying date is on June 28th, 2008, application number is that the patent application of CN200810022382.2 discloses a kind of multi-wedge type pulley forming method, this method has proposed four procedures through punching press, flange, pre-shaping and moulding, in spinning process, annular groove by the flange wheel is realized drum wall, and drum wall is thickened, make many wedges V-shaped groove belt pulley by pre-shaping and moulding then.But many wedges wheel rim that this application does not propose a concrete moulding thickens the spinning belt pulley product.In addition, said method comes down to by axial pressure and the radially spacing of assistant formation flange wheel drum wall to be thickened, the wall unevenness of the drum wall after thickening even, cause certain difficulty for follow-up wedge slot pre-shaping and moulding, be easy to generate discontinuity and the flute profile material is filled out discontented phenomenon, cause producing flute profile angular distortion situation, reject rate is higher.
Summary of the invention
Technical problem to be solved in the utility model is, overcomes the deficiencies in the prior art part, and a kind of motor car engine water pump that provides a kind of concrete wheel rim of making by rotary pressure technology with steel plate to thicken separately thickens the spinning belt pulley product with many wedges wheel rim.
The technical solution adopted in the utility model comprises wheel rim and spoke, in the middle of spoke, be provided with center hole and mounting hole, the thickness of described spoke is 2.25～2.5mm, the thickness of described wheel rim is 3.2～3.5mm, on wheel rim flat circle perisporium, be spun to the V-type groove, be spun to lower edge and upper edge in two ends up and down at the V-type groove.
The bottom land of described V-type groove is 1.2～1.5mm apart from the thickness of wheel rim inwall.
The utility model beneficial effect compared with prior art is: under the situation that belt pulley has higher requirements to flange thickness, can adopt thin blank to process, in the course of working wheel rim is thickened separately, this has just reduced the overall weight of belt pulley, thereby light in structure, material is economized, surperficial mechanical strength height, and dimensional accuracy height.

Embodiment
Provide embodiment of the present utility model below in conjunction with accompanying drawing.
As shown in drawings, the technical solution adopted in the utility model comprises wheel rim 1 and spoke 2, in the middle of spoke 2, be provided with a center hole 3 and four mounting holes 4, the thickness of described spoke 2 is 2.25～2.5mm, the thickness of described wheel rim 1 is 3.2～3.5mm, on wheel rim 1 flat circle perisporium, be spun to V-type groove 1-1, be spun to lower edge 1-2 and upper edge 1-3 in two ends up and down at V-type groove 1-1.
The bottom land of described V-type groove 1-1 is 1.2～1.5mm apart from the thickness of wheel rim 1 inwall.
V-type groove 1-1 on described wheel rim 1 and spoke 2 and the wheel rim 1 and V-type groove 1-1 be lower edge 1-2 and upper edge 1-3 steel plate one rotary press modelling on spinning machine at two ends up and down, and concrete making step is as follows:
1, blanking: plate is put into the blanking die of stamping press, process the circular flat blank material of the size that suits the requirements;
2, stretch: stretch among the upper die tooling of circular flat blank material being put into stamping press and the bed die, make reclinate rim section of edge formation of circular flat blank material;
3, integer: the blank after will stretching pushes among putting into the upper die tooling of stamping press and bed die, makes wheel rim form drum wall;
4. thicken: the blank that will form drum wall is put among the upper die tooling and bed die of spinning machine, described upper die tooling and bed die have ring side bumper edge, to play the effect that the restriction blank extends up and down, at upper and lower mold cramping blank and when driving its rotation, will be in the radially feeding of flat wheel of wheel rim arranged outside, when flat wheel is fed into when blank and bed die are close to, under the acting in conjunction of axial force and left and right sides radial force up and down, make thickness uniform in-plane peripheral wall of wheel rim formation;
5. pre-shaping: clamp at upper and lower shaping die under the situation of part blank rotation, radially feeding is taken turns in pre-shaping, forms initial multiple wedge slot on the flat circle perisporium;
6. moulding: clamp at upper and lower forming die under the situation of part blank rotation, briquetting roller is feeding radially, is spun to many wedges wheel rim and thickens the spinning belt pulley product.
