Problems solved by technology

The main disadvantage of these traditional processing methods is low production efficiency, which is only suitable for single-piece and small-batch production
In addition, due to the large volume, some have to be processed by two segmented molding and then butt jointed into a whole, which not only makes the process more complicated, but also reduces the reliability of product strength.

Embodiment 1

[0012] 1. Cutting material: Figure 1a Shown is the end view of the width direction of the strip to be cut, and its width H should be equal to the required width of the two rim parts.

[0013] 2. Bending: firstly stretch the small bend of the rim mechanically, Figure 1b Shown are the dimensions required to place the Figure 1a The two long sides of the strip shown in are bent up to give the strip a grooved shape. Next, stretch the rim in a big bend, Figure 1c Shown is to Figure 1b The two long sides of the groove-shaped material strip in the middle are bent again, and the material strip is Ω-shaped.

[0014] 3. Then carry out rounding, and roll the strip after two stretches into figure 1 Cylindrical shape shown in d.

[0015] 4. Butt weld the interface E of the rolled cylinder ( figure 1 d).

[0016] Five, cut off, in figure 1 The center position shown in e cuts the cylinder into two sections, which become two rim parts, and then respectively welds with the groove...

Embodiment 2

[0017] Embodiment two: if Figure 2a As shown in -b, two rims and two retaining rings are processed at one time, and its processing method is: 1. Cutting, its blanking width should be equal to the width of the two rims and two retaining rings. 2. Rounding. After cutting the material, the strip material is first rolled into a cylinder on the plate rolling machine. 3. Butt weld the interface. 4. Roll the cylinder into the required shape on the corresponding rolling die. Five, in Figure 2b The profile is cut in the position shown into four wheel components, two rims and two retaining rings.

Abstract

The machining process of engineering machinery wheel assembly includes the following steps: cutting strip material in the width of even number times the required assembly width; rolling to form the required sizes and shape; rounding to form cylinder; butt welding; and cutting to form even number assemblies. The symmetrical machining process has balanced outer forces, no torque and good forming effect as well as high production efficiency and low cost, and is especially suitable for mass production.

Description

technical field [0001] The invention relates to a processing method for engineering machinery wheel parts, which belongs to the category of mechanical processing. Background technique [0002] Since the wheels of construction machinery vehicles are larger and heavier than those of ordinary cars, the processing of its wheel parts is also relatively difficult. At present, the components of engineering machinery wheels are usually processed by thermal forming or spinning forming, and only one wheel component can be processed at one time. The main disadvantage of these traditional processing methods is low production efficiency, which is only suitable for single-piece and small-batch production. In addition, due to the large volume, some have to be processed and formed by the method of butt jointing into a whole after two segmental molding, which not only makes the process more complicated, but also reduces the reliability of product strength. Contents of the invention [00...
