Abstract

The present invention relates to a fabrication technology for weldless steel fellies. The present invention adopts the steps that intermediate blanks are formed from cast steel blank pipes by baiting, heating and rolling extending, and then, the steel intermediate blanks are made up fellies by rotary extrusion and shaping. Due to adopting the cast steel blank pipes as raw materials, large-caliber thin-wall weldless steel pipes are left out, which causes the cost to be reduced. During the machining process of heat rolling extending, the casting-state structure of the cast steel blank pipes is changed into smithing structure. The following rotary extrusion machining is cold machining, which not only can improve the machining precision of the fellies, but also can improve the material strength of the fellies about twenty percent by cold work machining. The fellies made by the technologic method do not have welding seams, and made-up wheels do not leak gas in the use process, which can be used for tubeless wheels of high-speed heavy-loading transport vehicles and has the advantages of high safety and reliability, oil consumption saving, etc. Rolling extending equipment, rotary extrusion equipment and shaping equipment which are made in China can be chosen for use during the fabrication process of the weldless steel fellies. The technology is the fabrication technology for weldless steel fellies for few investments and low production cost of products.

Description

A kind of no-seam steel felly making process
Technical field
The present invention relates to the manufacturing technology of steel automobile wheel, a kind of no-seam steel felly making process.
Background technology
Steel wheel is the wheel that is widely used at present on the automobile, particularly on truck.Steel wheel generally is made up of spoke and wheel rim two parts, makes respectively, and then welds together.Wherein the manufacturing process of wheel rim is concluded following several scheme: 1, shaped steel steel coil strip/welder's skill; 2, dull and stereotyped steel coil strip/weld/roll technology; 3, seamless steel pipe revolves/rolls technology.The wheel rim of scheme 1 and scheme 2 manufacturings forms with shaped steel or the weldering of band coil of strip, and the weld seam of a perforation is all arranged on the wheel rim.With this wheel that the wheel rim manufacturing of weld seam is arranged, in the use, be difficult to guarantee that the weld seam on the wheel rim is air tight under frequent alternate stress effect.So, this class wheel rim be mainly used in the underloading automobile inner tube-free wheel or in carry the having on the inner tube of a tyre wheel of automobile.Process program 3 is to use large-caliber thin-walled weldless (seamless) steel pipe (tube), is spun into the straight tube of unequal section through spinning machine, rolls the formation wheel rim with roll forming machine again.This wheel rim does not have weld seam, no matter in use be heavy duty or under the alternate stress effect, can not leak gas with the wheel of its manufacturing, and safety, reliable.This wheel rim can be applied on the inner tube-free wheel of high-speed overload haulage vehicle.But make wheel rim with process program 3, need the large-caliber thin-walled weldless (seamless) steel pipe (tube) of high-quality and the roll forming machine of import, production cost is very high.
Summary of the invention
The objective of the invention is to propose a kind of no-seam steel felly making process, can use more cheap raw material of price and the less home equipment of investment.
The step of this no-seam steel felly making process is: tubular blank is rolled over expand into intermediate blank, again intermediate blank is made wheel rim through spinning, shaping.Described tubular blank is the cast steel base pipeline section that the by volume constant principle of cast steel base pipe is cut into.Then cast steel base pipeline section is heated to forging temperature, rolles over expansion with Ring Rolling Machine again and form intermediate blank, the middle part internal diameter of intermediate blank is identical with the internal diameter at finished product middle part, and the two ends diameter is bigger, and becomes toroidal.The operation of described spinning be with spinning wheel from the middle part of intermediate blank to two ends mould pressing progressively.
This no-seam steel felly making process has saved large-caliber thin-walled weldless (seamless) steel pipe (tube) owing to adopt cast steel base pipe as raw material, and cost is reduced.Roll in the expansion process in heat, the as-cast structure of cast steel base pipe will be changed into the forging tissue.The rotary pressing processing of carrying out is cold working subsequently, not only can improve the machining accuracy of wheel rim, and can improve rim material intensity about 20 percent by cold-working processing.Wheel rim with this process manufacturing does not have weld seam, and the wheel of making in use can not leak gas, and can be used for the inner tube-free wheel of high-speed overload haulage vehicle, have safe and reliable, save advantage such as oil consumption.The all existing home equipment of equipment, spinning machine and shaping device is expanded in used rolling can be for selecting for use.Therefore, this technology is a kind of small investment, the no-seam steel felly making process that the production cost is low.
Description of drawings
Fig. 1 is the process route view of this no-seam steel felly making process;
Fig. 2 is the structure chart of automobile steel wheel made.
The specific embodiment
As shown in Figure 1, the step of this no-seam steel felly making process is: (a) cast steel base pipe blanking → (b) heating → (c) rolling expansion → (d) spinning → (e) shaping.
(a) blanking: the by volume constant principle of the effective sawing machine of cast steel base is cut into pipeline section.
(b) heating: the cast steel pipeline section is heated to forging temperature with heating furnace.
(c) roll over expansion: the pipeline section after will heating with Ring Rolling Machine is rolled over and is diffused into the intermediate blank size.Roll in the expansion process, as-cast structure is modified into the forging tissue.The shape of intermediate blank as shown in the figure, the internal diameter at middle part internal diameter and finished product middle part is identical, the two ends diameter is bigger, and becomes toroidal.
(d) spinning: will roll over power spinning machine and to expand the intermediate blank spinning obtain to finished size.In the spinning operation, used spinning block is two halves from the minimum punishment of diameter, the two halves mould therefrom between the two ends of base insert, lump together mutually, then with spinning wheel from the middle part of intermediate blank to two ends mould pressing progressively.
(e) shaping:, make its geometric accuracy reach the product design document requirement with the product shaping of sizing die after with spinning.
At last with punch press at the wheel rim upper punch aperture of door of giving vent to anger.
The process of spoke is: steel plate blanking → punching → spinning → and towards air vent → crowded counterbore → machined.
The spoke that processes is press fit into the ad-hoc location of the wheel rim that processes,,, promptly finishes wheel as shown in Figure 2 again through surface treatment with the argon arc welding.1 is wheel rim among Fig. 2, and 2 is spoke, and 3 is weld seam.

Claims (2)

1. no-seam steel felly making process, the steps include: intermediate blank is expanded in the tubular blank rolling, again intermediate blank is made wheel rim through spinning, shaping, it is characterized in that described tubular blank is the cast steel base pipeline section that the by volume constant principle of cast steel base pipe is cut into, then cast steel base pipeline section is heated to forging temperature, roll over to expand with Ring Rolling Machine again and form intermediate blank, the middle part internal diameter of intermediate blank is identical with the internal diameter at finished product middle part, the two ends diameter is bigger, and one-tenth toroidal, the operation of described spinning be with spinning wheel from the middle part of intermediate blank to two ends mould pressing progressively.
