Technical Field

[0001] This utility model relates to the field of wheel rim processing technology, and in particular to a wheel rim pressing mold for forklift pneumatic tires. Background Technology

[0002] The rim pressing mold for forklift pneumatic tires is a specialized tooling equipment mainly used to firmly and precisely press the rim (wheel ring) and hub (or spokes, disc) together to form a complete forklift wheel assembly.

[0003] However, in the existing technology, most wheel rim pressing molds do not have a buffer mechanism in the lower mold. Therefore, excessive pressure during the pressing process can easily damage the mold, thereby reducing the pressing effect of the wheel rim. Moreover, after pressing, the wheel assembly is mostly removed manually, which poses certain safety hazards. In addition, the wheel rim is heavy and inconvenient to handle, which is time-consuming and labor-intensive, greatly reducing the pressing efficiency of the wheel rim. Utility Model Content

In this utility model, the wheel hub is placed on the support plate, and then the wheel rim is fitted over the wheel hub to align the two. Then, the hydraulic cylinder is activated to drive the upper die head to move downward, so that the positioning mandrel is embedded in the center of the wheel hub. Then, pressure is applied to the wheel rim to press it evenly into the locking groove of the wheel hub, completing the edge rolling or engagement. During the pressing process, the buffer spring and buffer rod are embedded into the buffer groove with the pressure to buffer the impact force of the pressing, so that the upper die head can better press the wheel rim, reduce the impact force to damage the support plate and the pressing table, and improve the pressing effect. After the pressure reaches the set value or the stroke is in place, the pressure is held for a moment, and the hydraulic cylinder drives the upper die head to return. The first electric push rod pushes the support plate to move the wheel assembly out of the pressing groove, so that the support plate is flush with the outer surface of the pressing table. No manual snapping is required, which greatly improves safety and processing efficiency.
