Thread rolling machine

Abstract

The invention relates to forming roller machining, in particular to a thread roller. The thread roller comprises a machine body, a gearbox and an electric cabinet. The machine body comprises an upper main machine body and the lower main machine body. The upper main machine body, the gearbox and the electric cabinet are all fixedly disposed on the lower main machine body, a variable-frequency motor is arranged in the lower main machine body, and two rotary output shafts are arranged in the gearbox; the two ends of the upper main machine body are arranged on the side walls of the machine body respectively, a fixed main shaft base is fixedly arranged on the inner side of the side wall, at one end of the upper main machine body, of the machine body, a hydraulic cylinder is fixed to the inner side of the side wall, at the other end of the upper main machine body, of the machine body, a piston of the hydraulic cylinder is connected with a movable main shaft base, a sliding guide rail is disposed on the upper main machine body, the movable main shaft base slides along a sliding guide rail, a fixed main shaft is arranged in the fixed main shaft base, a movable main shaft is arranged in the movable main shaft base, the movable main shaft is connected with a rotary output shaft of the gearbox through a universal joint II, and the fixed main shaft is connected with the rotary output shaft of the gearbox through a universal joint I. Machining precision and consistency of threads are improved, and automatic work of the thread roller can be achieved easily.

Description

technical field [0001] The invention relates to forming roll processing, in particular to a thread rolling machine. Background technique [0002] At present, the configuration of domestic thread rolling machines is relatively low, and the degree of digitalization and humanization is low. Its structure mostly adopts split fuselage. Due to its poor rigidity, the split fuselage needs to be connected by tie rods to enhance the rigidity of the fuselage. However, due to the existence of tie rods, the operation space will be greatly reduced, and the installation of automatic mechanisms is limited, making it difficult to realize automation; The spindle speed of the existing thread rolling machine is mostly adjusted by the multi-stage speed of the hanging wheel box. The operation panel is a button station structure, and the proximity switch is used to send signals for timing. There are discontinuous adjustments of the spindle speed, the operation panel is not intuitive, and the adjus...

[0002] At present, the configuration of domestic thread rolling machines is relatively low, and the degree of digitalization and humanization is low.

Its structure mostly adopts a split fuselage. Due to the poor rigidity of the split fuselage, a tie rod connection is needed to enhance the rigidity of the fuselage. However, the existence of the tie rod will greatly reduce the operating space, and the installation of the automation mechanism is limited, making it difficult to realize automation; The spindle speed of the existing thread rolling machine is mostly adjusted by the multi-stage speed of the hanging wheel box. The operation panel is a button station structure, and the proximity switch is used to send signals for timing. There are discontinuous adjustments of the spindle speed, the operation panel is not intuitive, and the adjustment of the sending position is not accurate. And other issues
