  • the invention relates to forming methods of wheels, and particularly relates to forming methods of one-piece weldless wheels made of metal sheets..
  • the methods for manufacturing wheels made of metal sheets include that manufacturing wheel rims and wheel discs separately, and then integrating the wheel rims and the wheel discs into the whole wheels by welding.
  • the specific process may include the following steps:
  • the wheel made of metal sheets manufactured by the above methods has welding seams 3 between the wheel rim 1 and the wheel disc 2.
  • the wheel will not perform well on strength and rigidity, and fatigue breaks will be easily generated at the welding seams 3 and the butt welding seam 4.
  • the present invention is directed to provide a forming method of a one-piece weldless wheel made of metal sheets.
  • the method of the present invention can significantly reduce the manufacturing steps, and thus significantly improve the production efficiency and produce the wheels with high strength and rigidity performance as well as long service life.
  • the method of the present invention also can produce the wheels with high precision.
  • the strength of all of the force-bearing surfaces of the wheel manufactured by the method is equal, while the thicknesses of the wheel are different.
  • the method of the present invention does not include the step of welding, and the wheel manufactured by the method has no welding seam. Thus, air leakage will not happen in the wheel of the present invention and thus the air tight test can be omitted.
  • the present invention provides a forming method of a one-piece weldless wheel made of metal sheets, comprising the following steps:
  • the rolling of the forming method of a one-piece weldless wheels made of metal sheets according to the present invention is preferably a planar synchronous staggered rolling.
  • the staggered rolling refers to a kind of rolling that the rolling wheels are disposed mutually staggered in their initial positions in order to prevent the rolling trajectories of the rolling wheels on the surface of the circular blank from coinciding to ensure the surface of the circular blank more compact or denser.
  • the forming method of a one-piece weldless wheel made of metal sheets according to the present invention further comprises a step of forming the circular blank and punching a positioning hole which is used for positioning the circular blank stably into the rolling mould before the step (1).
  • the forming method of a one-piece weldless wheel made of metal sheets according to the present invention further comprises a step of extruding a center hole between the step (3) and the step (4).
  • the forming method of a one-piece weldless wheel made of metal sheets according to the present invention further comprises a step of extruding screw holes between the step (3) and the step (4).
  • the forming method of a one-piece weldless wheel made of metal sheets according to the present invention further comprises a step of extruding air holes between the step (3) and the step (4).
  • the forming method of a one-piece weldless wheel made of metal sheets according to the present invention further comprises a step (5) of punching a valve hole on the one-piece weldless wheel made of metal sheets.
  • rolling motions of the at least two rolling wheels in the step (1) comprise feed movements of the at least two rolling wheels in a horizontal direction and a rotation of each rolling wheel.
  • step (3) pressing the primary wheel rim in the radial direction of the wheel blank by using three lateral pressing rollers, in order to extrude and further form the primary wheel rim precisely, wherein the three lateral pressing rollers are arranged evenly along the circumferential direction of the wheel blank.
  • the present invention also provides a one-piece weldless wheel made of metal sheets manufactured by the above-mentioned forming method of a one-piece weldless wheel made of metal sheets.
  • the one-piece weldless wheel made of metal sheets of the present invention, wherein the one-piece wheel is made from carbon steel, aluminum, Mg-Al alloy or stainless steel.
  • the forming method of the one-piece weldless wheel made of metal sheets of the present invention is quite different from the methods of manufacturing the wheels made of metal sheets in the prior art.
  • the methods of manufacturing the wheels made of metal sheets in the prior art need to produce a wheel rim and a wheel disc separately and then weld the wheel rim and the wheel disc into a whole wheel having welding seams.
  • the present invention provides an integral forming process differentiating from the prior art. The differences in view of the prior art are mainly listed as follows:
  • the steps of the forming method of the one-piece weldless wheel made of metal sheets according to the present invention are much less than the steps of the prior art.
  • the forming method of the one-piece weldless wheel made of metal sheets according to the present invention can significantly improve the production efficiency.
  • the forming method of the one-piece weldless wheel made of metal sheets according to the present invention can produce a one-piece wheel by using the method including the steps of rolling and roll forming without butt welding, which greatly improves the rigidity, strength and lifetime of the wheel. Accordingly, the devices consumption, such as butt welding device, air extracting device and the like, can be omitted and power consumption of the devices can be saved accordingly. And the pollution (such as the spatter and the smoke) to the environment caused by the welding can be avoided.
  • the one-piece weldless wheel made of metal sheets manufactured by the forming method of the one-piece weldless wheel made of metal sheets according to the present invention is safer because there is no welding seam on the wheel, and thereby the regular air tight test on the wheel can be omitted.
  • the one-piece weldless wheel made of metal sheets manufactured by the forming method of the one-piece weldless wheel made of metal sheets according to the present invention can be used in passenger vehicles and commercial vehicles as well.
  • Figure 2 shows a schematic flow diagram of an embodiment of the forming method of the one-piece weldless wheel made of metal sheets according to the present invention.
  • Figures 3-14 respectively show each step of the flow diagram represented in Figure 2 .
  • a one-piece weldless wheel made of metal sheets is manufactured by steps as follows:
  • the step of roll forming is performed by a vertical cold rolling and roll forming machine shown in Figure 15 .
  • this vertical cold rolling and roll forming machine shown in Figure 15 is merely one kind of devices which can achieve the step of roll forming and cannot be deemed to be a limitation to the present invention.
  • the vertical cold rolling and roll forming machine in the embodiment includes a frame including upper beam 51, base 52, base support bracket 53 and six upright posts 54 fixedly disposed between the upper beam 51 and the base 52.
  • the six upright posts 54 are evenly disposed on a circumference centered on the axis of the vertical cold rolling and roll forming machine. Namely, the angle between two adjacent upright posts 54 is 60 degree.
  • Lower transmission assembly 55 is disposed on the base 52.
  • Three oil cylinder assemblies 56 are fixedly disposed on the upper beam 51.
  • the rods of the oil cylinder assemblies 56 fixedly connect to sliding blocks 57 connecting to an upper press head assembly 58.
  • the oil cylinder assemblies 56 can drive the upper press head assembly 58 to move along the axial direction (i.e.
  • Hydraulic motor(s) connect with the lower transmission assembly 55 and the upper press head assembly 58, in order to drive the lower transmission assembly 55 and the upper press head assembly 58 respectively rotate around the axial thereof in synchronization manner.
  • Three lateral pressing roller assemblies 59 are evenly arranged on a circumference centered on the axis of the vertical cold roll forming machine. That is, the angle between two adjacent lateral pressing roller assemblies 54 is 120 degree.
  • Each of three oil cylinders for the lateral pressing rollers connects to each lateral pressing roller assembly 59 respectively, in order to drive the lateral pressing roller assembly 59 to move in the radial direction of the circumference. These three lateral pressing roller assemblies can be moved synchronously or separately.
  • Hydraulic motor(s) for the lateral pressing rollers connects with the lateral pressing roller assemblies 59 to drive each of the lateral pressing roller assemblies to rotate around the axis itself.
  • the hydraulic motor(s) for the lateral pressing rollers can drive three lateral pressing roller assemblies to rotate synchronously or separately.
  • a convex roll forming mould 510 fixedly connects to the upper press head assembly 58.
  • a concave roll forming mould 511 fixedly connects to the lower transmission assembly 55.
  • the vertical cold rolling and roll forming machine further includes a control system which is not illustrated in the figures.
  • the control system may comprise displacement sensors respectively disposed on each feeding mechanism for the lateral pressing rollers, being used for detecting the feeding position of the lateral pressing roller assemblies; servo valves respectively connected to the hydraulic motor(s), the oil cylinders for the lateral pressing rollers and the hydraulic motor(s) for the lateral pressing rollers; PLC (programmable logic controller) connected to the displacement sensors, the servo valves and the oil cylinder assemblies, being used for controlling the rotating rates and feeding speeds of each element.
  • PLC programmable logic controller
  • the position of the lateral pressing roller assemblies in the axial direction (i.e. a vertical direction) of the vertical cold rolling and roll forming machine can be adjusted via an adjustment mechanism for the lateral pressing rollers which is connected to the lateral pressing roller assemblies.
  • the roll forming process using the above-mentioned vertical cold rolling and roll forming machine including the following steps:
  • Figure 16 shows a one-piece weldless wheel made of metal sheets, which is manufactured by above-mentioned steps. It can be seen from the figure that the shape of the one-piece weldless wheel made of metal sheets is the same as the shape of the wheel made of metal sheets in the prior art, while the one-piece weldless wheel made of metal sheets has no welding seam on the interim area between the wheel rim and wheel disc, which results in that the one-piece weldless wheel made of metal sheets has a much better performance on strength, rigidity and lifetime than the wheel made of metal sheets in the prior art.
