Abstract

The invention relates to a spline shaft hot forging device. The spline shaft hot forging device comprises an upper die, a lower die and a cylinder locking device. The upper die is composed of a punch, four screws, a positioning plate and an upper guide sleeve. The upper guide sleeve and the positioning plate are connected and fixed through the four screws. The punch is arranged at the central position between the upper guide sleeve and the positioning plate. The positioning plate is connected with a punching device. The lower die is composed of a lower female die, a lower material fixing die, a bolt and a lower die holder. The lower female die and the lower material fixing die are arranged at the central position of the lower die holder. The lower female die is located above the lower material fixing die. The bolt is located on one side of the lower die holder. The cylinder locking device is composed of a round sleeve and a reciprocating stroke cylinder. The round sleeve is connected with the movable head end of the reciprocating stroke cylinder. The opening end of the round sleeve is located in the protruding head end of the lower die holder. The spline shaft hot forging device has the beneficial effects that machining procedures can be reduced, the machining cost is low, and the forge piece error range is small.

Description

technical field [0001] The invention belongs to the technical field of hot forging processing devices, in particular to a spline shaft hot forging processing device. Background technique [0002] The general forging processing method is: hot forged spline shaft products are generally forged on a flat forging machine; the flat forging machine has two mutually perpendicular parting surfaces, and the main parting surface is between the punch 12 and the die 11. The other parting surface is between the two divisible halves of the die, and the die forging process is as follows: figure 1 ; [0003] Put the heated bar in the cavity of the fixed die M1, and determine the length L1 of the blank with the front baffle or the rear baffle; figure 1 As shown in -a; the main slider and the clamping slider of the flat forging machine move at the same time, when the die 11 clamps the bar (such as figure 1 -b), the main slider continues to move, the part of the bar length L1 is deformed und...
