Abstract

A spoke-rim integrated wheel, which is formed by spokes (1) and a rim (3). The spokes (1) and the rim (3) are formed by integral rotary pressing, so the spokes (1) and the rim (3) constitute an integral wheel (5) with an integrated structure. The spokes (1) and the rim (3) are made of the same material by rotary pressing. The wheel is an integrally molded product without an assembly jointing surface and a welding seam filler, and the spokes (1) and the rim (3) of the wheel are machined from the same blank material, so the overall material properties are consistent. Moreover, as the whole wheel formed by the spokes (1) and the rim (3) has no assembly jointing surface, welding lines (2) or welding fillers, the whole transition surface between the spokes (1) and the rim (3) is continuous, flat and attractive.

Description

Spoke wheel rim integrated wheel

Technical field

The invention belongs to the technical field of large automobile wheels, and particularly relates to a spoke rim integrated wheel.

Background technique

Since the production of existing large-scale automotive steel wheels is basically made up of spokes and rims and then welded to form a combined steel wheel; the conventionally produced spokes and rims are manufactured on two production lines respectively. After the two parts are manufactured, they are assembled together on the assembly line, and welded and synthesized. As shown in Fig. 1, the conventional wheel is composed of two parts of the spoke 1 and the rim 3, and the spoke 1 and the rim 3 are connected by the welding line 2. The welding line is respectively distributed on the inner side and the outer side of the spoke 1 and the rim 3 joint seam; therefore, the wheel assembly is characterized by having a closed weld around the circumference of the wheel; since the wheel is welded, the pole is in use It is easy to break the wheel from the weld seam, thus hiding great safety hazards.

Summary of the invention

The object of the present invention is to provide a spoke-wound rim integrated wheel integrally formed without a welded joint structure in view of the deficiencies of the prior art wheel combination technology.

The invention is realized by the following technical solutions: the spoke rim integrated wheel is composed of spokes and rims, characterized in that the spokes and the rim are integrally formed by spin molding, so that the spokes and the rim are integral structural integrated wheels.

The spokes and the rim are composed of the same raw material spinning.

The beneficial effects of the present invention are as follows: Compared with the prior art, the present invention adopts an integrally formed product without a joint surface and a weld filler, and the spokes and rims of the wheel are processed by the same blank material. Therefore, the overall material performance is consistent; and the wheel composed of the spoke and the rim does not have any assembled joint surface, welding line and solder filler, so the transition surface between the entire spoke and the rim is continuous, smooth and beautiful.

The following are the specific names of the logos in the figure: 1 spoke, 2 weld line, 3 rim, 4 weld line, 5 integral wheel.

detailed description

As shown in FIG. 2, the spoke rim integrated wheel is composed of a spoke and a rim, and the spoke and the rim are integral wheels 5 integrally formed by spinning together using the same raw material, instead of the wheel combined with the spoke and the rim; Therefore the invention The integral wheel has no assembled joints, weld lines and solder fillers. The transition surface between the entire spoke and the rim is continuous, smooth and beautiful.

The processing steps of the integral wheel 5 of the present invention are:

In the first step, the circular blank is first placed.

The second step is sandblasting.

The third step is to punch the center positioning hole, 1. the workpiece is placed in the lower mold, 2. the outer circular coarse positioning center, the upper mold drives the punch downward, and the workpiece is punched with the center positioning hole.

The fourth step is to spin the “rough rotation”. 1. The workpiece is placed in the core mold, and the center is roughly fixed. 2. The upper pressure seat is lowered to position and compact the workpiece. 3. The spindle drives the workpiece to rotate, and the rotary wheel rotates. Pressure.

The fifth step is to spin the “fine rotation”. 1. The workpiece is placed in the core mold, and the quasi-center is finely tuned. 2. The upper pressure seat is lowered to position and compact the workpiece. 3. The main shaft drives the workpiece to rotate, and the rotary wheel rotates. Pressure.

The sixth step is to spin the “reverse rotation”. 1. The workpiece is placed on the core mold to fix the center. 2. The upper pressure seat drives the core mold down to position and compact the workpiece. 3. The spindle drives the workpiece to rotate. Spinning pressure.

The seventh step, the roll type, 1, the workpiece is placed on the workbench, and then enters, the lower roll type mold of the lower main shaft is inserted, 2, the front pressing mechanism presses the front end surface of the workpiece, 3, the upper main shaft goes down, the upper roll type mold Close to the outer circle of the workpiece, 4, the front pressure mechanism is withdrawn, the upper and lower spindles rotate at the same time, the rolling type starts, 5, the upper spindle feeds, and the workpiece is gradually deformed by extrusion until it is formed.

In the eighth step, the hole is punched, the bolt hole is placed, the workpiece is placed on the lower die of the punching hole, and the inner circle and the inner plane are positioned, and the punch is descended to punch the workpiece.

The ninth step, the center hole of the car, 1, the workpiece is positioned by bolt holes, 2, the hook pulls the workpiece, 3, the tool holder moves, the middle hole and the chamfer are processed.

In the tenth step, the bolt hole is thickened, the inner chamfering is performed, and the workpiece is positioned in the middle hole. After clamping with the chuck, the working table is ascended, and the multi-axle box performs rough reaming and chamfering on the workpiece.

In the eleventh step, the bolt holes are finely expanded, the outer chamfers, and the workpiece is positioned in the middle hole. After the chuck is clamped, the work table is advanced, and the multi-axle box performs fine reaming and chamfering on the workpiece.

The twelfth step, the finished product is tested and marked into the warehouse.

The integrated wheel of the invention is suitable for various types of automobile wheels manufactured by the steel size series, such as: 5.50F---16 6.00G---16 6.5G---16 7.00T---20 7.5V--- 20 8.00V---20 8.5V---20.
