Description

Technical Field

[0001] The utility model belongs to the technical field of spindle forging, and specifically relates to a large-scale hydroelectric spindle forging machine. Background Art

[0002] The spindle refers to the shaft that receives power from an engine or a motor and transmits it to other parts. The spindle is usually formed by mechanical forging. A forging machine refers to the mechanical equipment used for forming and separating in forging processing. It is a machine that does work on the blank with the kinetic energy generated by a heavy hammer falling or forced high-speed movement, causing plastic deformation of the blank.

[0003] In the prior art, forging machines are mainly used for metal forming, so they are also called metal forming machine tools. Forging machines form metals by applying pressure to them. Being powerful is their basic feature, so they are mostly heavy equipment. Forging machines are composed of forging hammers, mechanical presses, hydraulic presses, conveyor belts, and upsetting presses. During the forging process, the forging hammer is usually driven up and down by the hydraulic cylinder of the hydraulic press. The spindle embryo is placed on the surface of the workbench and is formed by the repeated hammering of the forging hammer.

[0004] In the prior art, the spindle forging machines on the market usually consist of a frame, a cylinder, a conveyor belt, and a workbench. The forging hammer installed below is driven up and down by the cylinder at the top. When the spindle is transported to the designated position, it will be sent to the surface of the workbench through a push rod for forging operations. However, the push rod is usually installed on the side of the conveyor belt. If the push rod on the side fails and the position of the spindle is deviated, the spindle will hit the fixed cutting heads on both sides of the workbench, posing a safety hazard. Therefore, a large-scale hydroelectric spindle forging machine is proposed to solve the above problems. Content of the Utility Model

However, the push rod is usually installed on the side of the conveyor belt 24. If the push rod on the side fails and the position of the main shaft push is deviated, the main shaft will hit the fixed cutting heads 32 on both sides of the workbench 33, posing a safety hazard. Therefore, in view of the above problems, a large hydroelectric main shaft forging machine is proposed. During the shaft forging operation, when the main shaft is transported to the designated position through the conveyor belt 24, it will be blocked by the first push plate 23 assembled at the front end of the conveyor belt 24.
