Forming method of flat square on flat fork shaft

Abstract

The invention discloses a forming method for an upper flat-square of a bottom fork shaft. The forming method comprises a heating device, a feeding part, a heating part and a conveying part are sequentially arranged on a support from top to bottom, and the feeding part comprises a rotary disc, a fixing shaft and a hopper. A plurality of sliding grooves for storing the bottom fork shaft are formed in the rotary disc and penetrate through the rotary disc in the radial direction of the rotary disc, a vertical through hole is formed in the fixing shaft and can communicate with the sliding grooves, and a stepping motor for driving the rotary disc to rotate is fixedly installed on the support. The heating part comprises a heating coil, the heating coil is located below the rotary disc, and the heating coil and the through hole are coaxially arranged. A dark box is arranged below the heating coil, a blind hole is formed in the dark box, and a photoelectric sensor is arranged at the bottom of the blind hole. The photoelectric sensor is in electric connection with the stepping motor. The conveying part comprises a conveyor belt, a plurality of vertical pipes are arranged on the conveyor belt, and check blocks are arranged in the middles of the vertical pipes and are slidably connected with the vertical pipes in the transverse direction. Heat expansion blocks are arranged between the vertical pipes and the ends, away from the vertical pipes, of the check blocks, and labor burden of workers is relieved.

Description

technical field [0001] The invention relates to a forming method of a flat fork shaft. Background technique [0002] The flat fork shaft is a fixed shaft installed on the motorcycle bracket. One end near the flat fork shaft is provided with a circle of radially protruding protrusions, which are called flat squares. The flat square is generally formed integrally with the flat fork shaft. The existing method is to heat the position on the raw material of the flat fork shaft that needs to be formed into a flat square through the coil, then place the heated raw material on the punching machine, and squeeze the raw material axially through the punching machine, so that the heating part is radially Raised to form a flat square. During processing, the worker needs to put the raw material into the heating coil for heating. After the heating is completed, the worker takes the raw material out of the coil by hand, and then places it on the punching machine. Workers' operations are ...
