Wheel rotary forging press die loading and unloading trolley

Abstract

The invention relates to a wheel rotary forging press die loading and unloading trolley which comprises a trolley frame, a primary sliding plate, primary rollers, a secondary sliding plate, an angle adjusting mechanism, a die placing plate, a rotating shaft, positioning pins, a position adjusting mechanism, secondary rollers, supporting rollers, trolley wheels and a locking mechanism. The die loading and unloading trolley is characterized in that the trolley wheels and the locking mechanism are mounted below the trolley frame, guide-track grooves are formed in the inner sides and the outer sides of a left side plate and a right side plate of the primary sliding plate, the primary rollers are positioned in the guide-track grooves in the inner sides and fixed onto the trolley frame, the secondary rollers are positioned in the guide-track grooves in the outer sides and fixed on the secondary sliding plate, the angle adjusting mechanism and the rotating shaft are mounted at two ends between the die placing plate and the secondary sliding plate respectively, the positioning pins are arranged on the primary sliding plate and the secondary sliding plate respectively, the position adjusting mechanism is mounted on the trolley frame, and the supporting rollers are mounted on the left side and the right side of the front end of the secondary sliding plate and can be supported on a wheel rotary forging press tabletop.

Description

technical field [0001] The invention belongs to the field of automobile wheel manufacturing, and relates to a trolley for loading and unloading molds of a wheel rotary forging press. Background technique [0002] The manufacturing process of automobile wheels includes casting, forging and spinning, etc. The wheel rotary forging press is the key equipment in the forging process of automobile wheels, mainly used to make billets. The wheel rotary forging press has two main shafts, upper and lower. The axis of the lower shaft is perpendicular to the horizontal plane, and is installed in the base of the wheel rotary forging press. inside the slider. The upper die of the wheel rotary forging die is installed under the upper main shaft of the wheel rotary forging press, and the lower die is installed above the lower main shaft. [0003] At present, the installation of the wheel rotary forging die is generally to place the die on a base with the same angle as the spindle mounting ...

AI Technical Summary

Problems solved by technology

[0004] The loading and unloading method of the above-mentioned wheel rotary forging mold uses a forklift to transport the mold, which requires a large operating space for the forklift to drive, but the internal space of the production workshop is small, and various equipment and lines are arranged, which is not convenient for forklift operation.

At the same time, the accuracy of the parking position of the forklift is very low, and it is difficult to accurately transport the mold to the ideal position. It is necessary to adjust the position of the forklift many times to align the mold with the installation position, and the loading and unloading efficiency is very low.

Moreover, using a forklift to load and unload the mold requires a special person to drive the forklift, which increases the demand for manpower

[0005] Due to the eccentric loading of the wheel rotary forging press when loading and unloading the mold, the simple loading and unloading mold trolley needs a heavy counterweight to prevent rollover, the structure is large and heavy, and there is no mold angle adjustment mechanism, which is very inconvenient to use
