Conveying method of car hub spinning production line

Abstract

The invention discloses a conveying method of a car hub spinning production line. The conveying method comprises the following steps that 1) a hub blank to be preheated is placed on a second conveyingbelt; 2) a first mechanical arm clamps the hub blank to be preheated from the second conveying belt; 3) a second mechanical arm firstly stretches into a furnace door to clamp the heated hub blank, and then the first mechanical arm stretches into the furnace door to place a hub blank to be preheated on a circular conveying rail; 4) the circular conveying rail conveys the hub blank to be preheatedto be rotationally preheated in a furnace, the hub blank to be preheated becomes a preheated hub blank after preheating is finished, and the preheated hub blank is conveyed to the furnace door; and 5)the first mechanical arm firstly stretches into a spinning machine to clamp a spun semi-finished hub, and then the second mechanical arm stretches into the spinning machine to place the preheated hubblank. The whole conveying method is designed according to the improved layout of the production line, the conveying method is smooth and ordered, the conveying benefit is greatly improved, and therefore the production rate is increased.

Description

technical field [0001] The invention relates to the technical field of automobile wheel hub manufacturing, in particular to a conveying method for an automobile wheel hub spinning production line. Background technique [0002] The wheel hub is a cylindrical metal part in the car tire that is centered on the shaft to support the tire. In layman's terms, it is the part where the axle is installed in the center of the wheel. It is an important part that connects the brake drum, the wheel disc and the half shaft. At present, the manufacturing of conventional wheels mostly adopts spinning forming. The spinning production line includes a preheating furnace and a spinning machine. The preheating furnace is used for preheating the workpiece to form a preheated wheel blank. The preheated wheel hub blank is subjected to spinning process to form the wheel hub semi-finished product. The furnace cavity of the existing preheating furnace is a rectangular structure, and the quality of the ...

Problems solved by technology

However, it not only occupies a large space in the longitudinal direction, but also the entrance and exit are located in different positions, so a preheating furnace needs to be equipped with at least two manipulators for placing and picking up parts, and the spinning machine also needs to be equipped with a Manipulators, so the whole production line needs at least three independently operating manipulators, which has the problems of higher equipment cost and insufficient production efficiency. At the same time, there are either operators at the entrance and exit, or one operator moves back and forth at the entrance and exit, causing inconvenience in operation. question
