Reversing device for train wheel transport

Abstract

The invention discloses a train wheel transport direction changing device, which belongs to a transfer device for workpieces in the metal rolling process. The conveying mechanism of the device is provided with a roller frame, rollers and a conveying motor; the rotating mechanism is provided with a slewing bracket, a slewing support, a rotating motor and a rotating base; Basically, the roller table frame of the conveying mechanism is placed on the support seat on the upper end surface of the slewing bracket, the lower end of the roller table frame of the conveying mechanism is rotated and connected to the oil cylinder of the lifting mechanism, and the oil cylinder pipeline of the lifting mechanism is connected to the hydraulic mechanism, the conveying motor, the rotating The motor and the hydraulic mechanism are electrically connected with the electric control device respectively. The advantage is that when the conveying mechanism of the device is lowered, the front end face is flush with the discharge roller table of the machine tool and the conveying roller table of the detection line, which reduces the butt joint gap between the two, and is suitable for train wheels of different specifications, especially small diameter wheels. Avoid slipping and falling accidents during transportation.

Description

technical field [0001] The invention belongs to a transfer device for workpieces in the metal rolling process, in particular to a production and transportation roller table for train wheels. Background technique [0002] In the wheel production plant, the rolled and formed train wheels are sent to the machine tool for finishing, and then sent to the inspection line for flaw detection and surface strengthening treatment. The structure of the delivery roller table for finishing processing is the same as that of the inspection line. , connected back and forth. In order to make the process layout compact and make reasonable use of the factory space, some factories set the finishing discharge roller table vertically with the inspection line roller table, and set up a direction changing device at the junction of the discharge roller table and the inspection line roller table to change the direction of the wheels to ensure Production went smoothly. At present, the direction chang...

Problems solved by technology

The existing problem is that in order to ensure the smooth transmission of the train wheels on the discharge roller table of the lathe to the conveying roller table of the detection line, the conveying chain plate of the conveying mechanism and the conveying roller table of the detection line are in the same plane. Considering the rotation of the direction changing device, the driving chain When the sprocket, driven sprocket, and conveyor chain plate are arranged, there is a certain turning distance between them and the conveyor roller table; in addition, the sprocket drive has a certain arc at the transmission end to increase the gap between the conveyor chain plate and the conveyor roller table. With the production of more and more train wheel specifications, the wheel diameter range is between φ600---φ1250, and the size is different. The large-diameter wheels can pass smoothly, but when the small-diameter train wheels pass through the reversing device, the wheels are easy. The gap between the conveyor chain plate and the conveying roller table slips, or even falls off the road. It is necessary to stop production to deal with the accidents of wheel slipping and falling off the road, which will affect the normal production and restrict the reasonable production. In severe cases, it will cause scratches on the surface of the wheel and affect the appearance of the wheel. quality; in addition, wheel slipping can easily cause sprocket and chain plate wear, replacement is troublesome, time-consuming and labor-intensive, labor-intensive, spare parts consumption increases, and production costs increase
