Description
Technical field
The utility model relates to belt pulley and makes field, particularly a kind of no spoke automobile decoupling zero motor pulley mfg. moulding die.
Background technology
Since two thousand eight, traditional electric motor of automobile belt pulley is gradually by a kind of patented product---and automobile decoupling zero motor belt wheel assembly (One-way clutch Alternator Decoupler is called for short OAD) replaces.Because the latter has greatly increased the flatness of electrical motor gearshift, can fuel-economizing more than 2%～3%, and its anti-fatigue ability doubles, so market prospects are very wide.
Automobile decoupling zero motor belt wheel assembly (OAD) is the patent of LITENS (Leiden) company in invention in 2003 at first; Through improving, do the change of some structures afterwards, and provided a kind of structure compact more New O AD; Structure is different slightly between the two; Its principle and function are basic identical, and Leiden company has applied for the patent of invention of automobile decoupling zero motor belt wheel assembly (OAD) in the China's Mainland, and its patent No. is ZL 03816543.0.
The method of making belt pulley emerges in an endless stream; Be to form tubular blank with plate, pipe or casting earlier for a long time mostly; After cut is removed the manufacturing process of excess stock, and catch up from behind because of the characteristics of its high-quality, high efficiency, material saving with the technology of rotation cold extrusion manufacturing belt pulley in recent years., the existing manufacturing process of the belt pulley in the automobile decoupling zero motor belt wheel assembly (OAD) still rests on original state, and tracing it to its cause mainly is: well-known; Automobile industry parts manufacturing technology standard and technological requirement are higher than other general industry parts manufacturer's standards, and very thin thickness at the bottom of the pulley groove among the OAD, if with the such belt pulley of rotation cold extrusion manufacturing; Swing roller must radially apply very big pressure to material base; But because it does not have spoke, material base can't be by reliable grip in rotation cold-stamped moulds of industrial equipment, because rotation cold extrusion equipment only can give the material base clamping force in the axial direction; And the face area of steel pipe material base is very little; So can't be by reliable grip, when swing roller was exerted pressure to material base, material base must skid and cause the manufacturing process failure.In view of this, do not see the manufacturing process of processing the OAD belt pulley with the spinning method up till now as yet.In fact, all rotation cold-extrusion technologies manufacturing automobiles use belt pulley all to require belt pulley for spoke architecture is arranged, so that feasible process at present.
The pulley body structure of decoupling zero electric motor of automobile belt pulley assembly (OAD) mainly contains two kinds at present, and the related no spoke OAD belt sheave structure of the utility model is wherein a kind of---no spoke thin-walled long barrel shape structure.The characteristics of this structure are that its barrel-shaped external diameter surface has a plurality of high-precision grooves, and bottom land thinnest part wall thickness only has 1.3 mm, and the cross section is shown in dash area in the accompanying drawing 1.The existing manufacturing process of the OAD belt pulley of this structure be with seamless steel pipe as material base, process many grooves of its outer surface through multiple turning and process, see Fig. 1.Its shortcoming is: production efficiency is low economically, and utilization rate of raw materials is lower, and first-time qualification rate is lower, and processing cost is high; Qualitatively, its appearance groove is difficult to turning to very high fineness (noise hidden danger is arranged when causing the automobile engine high-speed cruising), and simultaneously because its intensity of belt pulley of turning can only be possessed self intensity of steel pipe, so the intensity of belt pulley is not high.
Summary of the invention
To the problems referred to above, it is high that the purpose of the utility model is to design a kind of production efficiency, and utilization rate of raw materials is high, a kind of no spoke automobile decoupling zero motor pulley mould that qualification rate is high, processing cost is low and belt pulley intensity is good.
For achieving the above object; The technical scheme that the utility model provided is: a kind of no spoke automobile decoupling zero motor pulley mfg. moulding die; Comprise mode structure and following mode structure; Described upward mode structure is the high rigidity swiveling wheel that has bearing; Described mode structure down comprises left and right clamping device and the left and right plug of high rigidity; The pipe that described left clamping device and right clamping device will be enclosed within on the left and right plug of high rigidity is fixedly clamped, and the corresponding groove of tool being and not being spoke automobile decoupling zero motor pulley on the described high rigidity swiveling wheel is characterized in that: have one in described right clamping device and the left clamping device at least for the radially clamping device of the power of radially holding tightly is provided to pipe.
Further; The a kind of of described radially clamping device is collet; In comprising, holds by described collet collet, collet overcoat, square type spring tightly; Hold collet in described tightly and contain the distinguish mouth of pipe that a confession pipe inserts and clamps, and link to each other with the collet overcoat through square type spring.
Preferably, holding collet contact pipe surface element position in described tightly, to have a plurality of wedge angles protruding.
Further, described radially clamping device another kind is the hydraulic pressure three-jaw chuck.
Preferably, it is protruding that described hydraulic pressure three-jaw chuck contact pipe surface element position has a plurality of wedge angles.
Further, described pipe is a seamless steel pipe.
The described die production of the utility model does not have spoke automobile decoupling zero motor pulley manufacturing process: adopt above-mentioned no spoke automobile decoupling zero motor pulley mfg. moulding die, also comprise the steps:
Step 1: right plug of high rigidity and right clamping device are removed to the right together, and pipe is inserted on the plug of a high rigidity left side;
Step 2: right plug of high rigidity and right clamping device are moved to the left and high rigidity left side plug and left clamping device matched moulds together, and pipe is axially clamped and radially clamps;
Step 3: high rigidity left side plug, left clamping device, the right plug of high rigidity, pipe, right clamping device are rotated together;
Step 4: the high rigidity swiveling wheel that has bearing moves to pipe; Touch passive rotation behind the pipe but still continue to move forward; Pipe is non-slip being rotated at a high speed by the maintenance always all the time of high rigidity swiveling wheel shear spinning feeding, is extruded until pipe to reach given size, is shaped to no spoke automobile decoupling zero motor pulley semi-finished product; Remove the redundance on semi-finished product both sides, must not have spoke automobile decoupling zero motor pulley finished product.
Further, the described pipe of step 1 is inserted on the plug of a high rigidity left side by manipulator.
Further, the mold clamping force of the described matched moulds of step 2 is 80 tons.
Adopt technique scheme; The utility model is made the decoupling zero electric motor of automobile belt pulley with no spoke thin-walled long barrel shape structure with rotation cold-stamped mode, because this OAD belt pulley uses mould to adopt rotation cold extrusion shaped, the product design of processing is attractive in appearance; In light weight; Noise is little, and rotary inertia is little, good dynamic balance.Save material 15% than former technology economically, processing cost reduces by 20%, and first-time qualification rate is near 100%, thereby overall economic benefit can improve nearly 50%; Can reach Ra0.5 in the surface smoothness of groove qualitatively, simultaneously because flow harden proves that through overload trial the intensity of belt pulley can improve 40%.The alternative original manufacturing process that has or not the decoupling zero electric motor of automobile belt pulley of spoke architecture of the utility model technology has realized the process of low-cost and high-quality.
