Problems solved by technology
[0002] In the production of seamless steel pipes, in order to increase productivity, it is hoped that the auxiliary working time of the punching machine outlet table will be shortened to speed up the production rhythm. There are two sets of feeding devices, such as the transfer mechanism of Shanghai Baosteel’s φ140 seamless steel pipe piercing machine exit table, which uses two sets of feeding arms that are not on the same axis to work crosswise, the feeding arm is long, and the transportation time is long; There must be a gap time between the feeding devices to avoid the running interference of the workpiece, so the auxiliary working time is long

Embodiment Construction
[0017] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0018] Figure 1 is a transfer mechanism and track diagram of the ejector rod circulation of the exit table of a piercing machine according to the present invention. The transfer mechanism is composed of a crank connecting rod mechanism and a crank slider mechanism, that is, a material receiving mechanism and a material supporting mechanism; the material receiving mechanism is composed of a crank shaft 6, a material receiving arm 7, a rocker 20 and a base 15, and the material receiving arm is The connecting rod, the base is the frame, and the "V" is welded on the head of the material receiving body. Due to the rotation of the crankshaft 6 and the constraints of the rocker 20, the running track of the point A of the material receiving arm 7 is as shown in the figure. indicated at the point. The supporting mechanism is composed of the eccentric ...

A cyclic transfer mechanism for the ejecting rod on the discharge bench of perforating machine is composed of crank-connecting rod unit and crank-slide block unit, that is, material receiving unit and material supporting unit. Said material receiving unit consists of crank axle, receiving arms (connecting rods), rocker, and base (machine frame). Said material supporting unit consists of eccentric axle, eccentric wheel on said eccentric axle, supporting body with slide slot, locating pin (slide block) in said slide slot, and base. A group of receiving arms is installed to the long crank axle. A group of supporting bodies is installed to the eccentric axle.
Description
technical field [0001] The invention belongs to steel rolling machinery, and in particular relates to a transfer mechanism for the circulation of ejector pins on the exit table of a piercing machine in the production of seamless steel pipes.
