Abstract
The invention comprises a method of spinning a pulley using a tubular blank. A tubular blank (B) is placed in a spinning machine mandrel (10). The hub is formed by spinning down, or inward, one end of the tubular blank, while leaving the other end as a cup for either spinning a pulley or sprocket profile. This process results in natural thickening of metal at the hub by maintaining a constant volume of metal while reducing the diameter of the tube during the spinning process.
Description
Invention field
The present invention relates to the transmission of power pulley, relate more specifically to a kind of method that forms pulley by tubular blank spinning.
Background technology
Pulley and sprocket wheel extensively known and be used as a kind of between axle the device of transferring power.The transmission of power pulley can be made in many ways.Can process multiple laminated metal by mould pressing or pattern.In this method, the belt profile is to form in the radial motion of mould with respect to blank.
The United States Patent (USP) no.4 that is represented as people such as Hitchcock of this technology, 840,607 (1989), it has disclosed a kind of convex surface V-shape belt pulley of mould pressing, and this pulley is to utilize " can shape " blank, form at groove by the side along blank that pressurization forms to material in the zone.This invention can not provide flexibility on hub district thickness, also can not become single step technology.
Described prior art also depends on the blank of described can shape, and for web, this blank has suitable preform thickness.Only pulley is pressed into shape with existing preform web thickness.In addition, described preform requires to carry out the forming step of mould pressing step, thereby has increased the cost of finished product.The pulley dependence level of other prior art is shaped, and for example as United States Patent (USP) no.5, shown in 987,952, but this patent can not provide the plasticity of optimal laminated metal to flow for application described herein.This technology relies on from the middle part, lateral carries out rotary pressing processing to the lip-deep metal of circular blank, is shaped to form hub around a center rod until the metal that makes gathering.The described part of this technological requirement has certain diameter and requires its blank can assemble the metal of aequum.For the part with minor diameter or very long and/or thick hub, not having is enough to assemble institute's required amount metallic surface area.
Therefore, need a kind of method that can utilize tubular blank spinning to form pulley.Need be by inwardly assembling metal towards the hub end of tubular blank, forming the method for pulley by tubular blank spinning.Need to utilize the tubular blank that inwardly to assemble a large amount of gathering metals to come spinning to form the method for pulley.The present invention can satisfy these requirements.
Summary of the invention
Main aspect of the present invention is to provide a kind of method of utilizing tubular blank spinning to form pulley.
It is a kind of by inwardly assembling metal towards the hub end of tubular blank, being formed the method for pulley by tubular blank spinning that another aspect of the present invention is to provide.
Another aspect of the present invention is to provide a kind of method that is formed pulley by the tubular blank spinning that can inwardly assemble a large amount of gathering metals.
To point out or illustrate others of the present invention by the following description of this invention and respective drawings.
The present invention includes a kind of method of utilizing tubular blank spinning to form pulley.A kind of tubular blank is arranged in the axle of spinning machine.By forming hub downwards or to an end of internal rolling tubular blank, keep the other end simultaneously as a cup-shaped spare so that or spinning form the shape of pulley or sprocket wheel.This technology reduces the diameter of pipe simultaneously by keep the metal of constant basis during spinning process, thereby metal is thickeied naturally at the hub place.Subsequently, the edge with pulley is spun into desirable profile.
Description of drawings
Fig. 1 has shown a kind of profile of tubular blank.
Fig. 2 has shown the profile of the tubular blank on an axle.
Fig. 3 has shown when forming tubular blank, a kind of profile of forming rolls.
Fig. 4 has shown a kind of profile of the pulley that is shaped fully.
The specific embodiment
Fig. 1 has shown a kind of profile of tubular blank.Described tube-like piece or blank comprise the cutting members of pipe, or the bottom is by the deep drawn cup-shaped spare of punching.The length of tubular blank is L, and diameter is D
1, thickness is T
1
Fig. 2 has shown the profile of the tubular blank on an axle.By tubular blank B being arranged on the axle 10 with suitable dimension, begin described technology.Diameter D
1Can be enough between blank and axle, form slight interference fit, perhaps can blank be fixed on the axle by device known in the art.
Subsequently, by the headstock axle 10 and blank are rotated.Make forming rolls 12 radially and axially-movable by equipment known in the art, so that correctly form blank.In order to form pulley, axle is rotated.Forming rolls is moved to the position of being selected by the operator to be contacted with the sidepiece of tubular blank.When forming rolls inwardly moved, metal accumulated in tailstock hub position on every side to stablize swedged mode.Owing to by described technology the amount of metal is changed, therefore, when forming rolls inwardly moved, the diameter that reduces can make the hub portion thickening.
Fig. 3 has shown when forming rolls forms tubular blank, the profile of this forming rolls.As shown in the figure, with inside radial direction M
1Make forming rolls 12 motions.When forming rolls inwardly moved, metal was assembled in the forming rolls front, thereby at the diameter D of hub 14
2 Form hub 14 when reducing gradually.Make accumulation of metal and when forming rolls continues inwardly motion, form hub around tailstock 11.Forming rolls 12 can be followed the profile 15 of axle 10, so that partly give suitable shape to finished product.According to user's needs, the profile of web is tilted gradually, thereby form from the edge to the tapered profiles of hub district thickening.When forming rolls inwardly moves, also can adjust the path of forming rolls vertically, so that change the thickness of web 17.In this way, according to user's needs, the thickness of web tilted gradually, change or make its maintenance constant.Also web 17 spinning can be formed recessed or combined type or recessed/convex shape, with further reinforcement web.
Fig. 4 has shown a kind of profile of the pulley that is shaped fully.The inside diameter D of hub
3Width by tailstock 11 limits.The thickness of the metal of assembling at hub 14 places is T
2, it is much larger than green diameter T
1For the final hub that forms, subsequently, utilize along direction M
2The fine finishining roller 13 of motion forms the net shape of hub 14.Form the final profile or the shape of hub 14 according to the profile of fine finishining roller.Fine finishining roller 13 can have the desired any profile of user known in the art.The thickness of hub can remain T
2, or also can make it reduce to thickness T
3, to form a pulley.
In case form described parts, just take off this parts from axle, so that desired like that, edge or belt bearing-surface 16 finally are shaped by the user.Utilize a forming rolls (not shown) to form the belt bearing-surface.By metal forming apparatus, can make described belt bearing-surface form v shape band structure, multirib structure or other profile arbitrarily known in the art.
Though described a kind of form of the present invention herein, those skilled in the art obviously know: under the situation that does not break away from thought of the present invention described herein and protection domain, can fasten in the structure of parts and pass and make multiple change.
