Problems solved by technology

For the super-long parts such as integrally forged hand brake levers of railway wagons, which have a maximum length of more than 4.5m, it is difficult for general presses to have such a long worktable. Flashing occurs, causing trouble for subsequent cleaning, time-consuming and labor-intensive, and poor economic effect

Embodiment Construction

[0018] figure 1 It is the general assembly drawing of the roll forging machine, and the center distance of the rolls is A=1500mm. (1) The base is equipped with (2) motor base through bolts, and (2) motor base is equipped with (3) switched reluctance motor and (5) planetary gear reducer. (3) The switched reluctance motor and (5) the planetary gear reducer are connected together through a shaft coupling (4). (3) Switched reluctance motor drives (11) upper roll shaft and (15) lower roll through (5) planetary gear reducer, (6) intermediate drive pinion, (7) upper drive gear, (16) lower drive gear shaft, thereby driving (12) upper roll and (14) lower roll to rotate synchronously and reversely. (8) The floating gear and (7) the upper transmission gear are assembled through the groove on the end face and compressed with screws. (9) Inner frame and (13) Outer frame are connected into a whole by upper and lower (10) pull rods, guarantee that the overall rigidity of the machine is go...

Abstract

The invention discloses a Phi-1500 dedicated roll forging machine, which is used for an integral-forging hand brake pull rod on a roll-forging railway wagon. The Phi-1500 dedicated roll forging machine comprises a driving motor, a planetary reducer, a transmission gear system, a center distance adjusting device, a backlash eliminating device and a roller system. The Phi-1500 dedicated roll forging machine disclosed by the invention is directly driven by a switch reluctance motor and can drive a roller to synchronously and reversely rotate through the planetary reducer and a straight-gear transmission gear; and the center distance adjustment of the roller is carried out by adopting an oblique iron, the center distance is adjustable, the backlash generated during the center distance adjustment can be eliminated by adopting the corresponding backlash eliminating device, four roll forging dies can be arranged on the roller, and the maximum roll-forging length of a workpiece is 4100 mm.

Description

technical field [0001] The invention discloses a φ1500 special roll forging machine, which is used for integrally forging hand brake pull rods on railway wagons. Background technique [0002] In recent years, with the rapid development of railway transportation, the demand for high-speed and heavy-duty vehicles has become more and more urgent, which requires higher and higher requirements for vehicle components. [0003] As an important part of train lighting, the hand brake lever of railway freight cars has also greatly improved its strength and performance requirements. The hand brake lever of a traditional railway freight car is very long. Generally, the fork and the rod are processed separately, and then welded together. Due to manual welding, the quality of the weld joint fluctuates greatly, and the quality cannot be guaranteed. Railway failure often occurs during vehicle operation. The breakage of the hand brake lever of the truck from the welding joint has caused gre...
