Embodiment

[0033] Embodiment: A kind of manufacturing method of wheel-shaped component

[0034] See attached figure 1 And attached figure 2 As shown, the wheel-shaped part includes a plastic wheel 1, and the circumference of the plastic wheel 1 is D 1 , the plastic wheel 1 is provided with a circle of rubber belt 2 along its circumference, and the manufacture of the wheel-shaped part consists of the following steps:

[0035] Step 1: Prepare Materials

[0036] The general-purpose compound rubber on the market is mixed into rubber, and the general-purpose plastic particles on the market are processed into plastic particles with a diameter of 0.07 mm.

[0037] The rubber compound refers to the uncrosslinked and fluid rubber material mixed with the compounding ingredients in the block, granular and powder raw rubber. It is the blank for making rubber products, that is, the semi-finished product. When mixing rubber, no temperature is added to make it incompletely formed. The shape of the...

Abstract

The invention discloses a manufacturing method of a wheel-shaped part. The method is characterized in that rubber compound and plastic particles serve as raw materials, the plastic particles are pressed into a plastic wheel disk, the rubber compound is extruded into rubber strips, the rubber strips are sleeved on the periphery of the plastic wheel disk in a head-tail lap joint mode, the plastic wheel disk on which the rubber strips are sleeved is placed in a high-temperature mold, a semi-finished product is formed, at the same time, pressure is exerted, after the semi-finished product is taken out from the mold, constant-temperature shaping is conducted immediately, and finally finish machining is performed. During production, rubber and plastic are not only in physical connection, but also in chemical connection during high-temperature shaping, so that after total shaping, the joint area between the rubber and the plastic is increased and the joint strength between the rubber and the plastic are enhanced, and the service life of the part is prolonged greatly.

Description

technical field [0001] The invention relates to a wheel-shaped component, in particular to a manufacturing method of a small-sized wheel-shaped component. Background technique [0002] Often need to use small-sized wheel on ski car, gardening machine and some implements, this type of small-sized wheel requires self-weight to be light, so that the primitive power that needs in use process is little. The main body of such small wheels is mostly light metal, and rubber is attached to the surface of the light metal to ensure the necessary friction and power transmission. However, the production cost of small wheels with light metal as the main body is high and the production process is complicated. , Gradually, plastics replaced light metals and were widely used in such small wheels, but after plastics replaced light metals, new problems appeared, because the polarities of rubber and plastics were different, which affected the relationship between rubber and plastics. Indirect ...
