Feeding and discharging device for annular heating furnace

Abstract

The invention relates to the field of steel processing equipment, and particularly relates to a feeding and discharging device for an annular heating furnace. The feeding and discharging device comprises a rack, a trolley and a grabbing mechanism, wherein the trolley is arranged on the rack in a sliding mode, and the grabbing mechanism is arranged on the trolley; the grabbing mechanism comprises two parallel claw beams, the middle parts of the two claw beams sleeve the interior of a first double-hole bearing seat, the top of the first double-hole bearing seat is hinged to the bottom of the trolley, clamping pincers of which notches are opposite are respectively arranged one end of the two claw beams on the same side, the other ends sleeve the interior of a second double-hole bearing seat,a lifting air cylinder is arranged between the second double-hole bearing seat and the trolley, the telescopic end and the cylinder body end of the lifting air cylinder are respectively hinged to thetop of the second double-hole bearing seat and the bottom of the trolley, a clamping cylinder is arranged between the two claw beams, swing arms are respectively hinged to the telescopic end and the cylinder body end of the clamping cylinder, and the other ends of the two swing arms are fixedly connected with the two claw beams respectively. According to the feeding and discharging device, the degree of automation of feeding and discharging processes of the annular heating furnace can be increased, and remote operation control is realized.

Description

technical field [0001] The invention relates to the field of steel processing equipment, in particular to a loading and unloading device for an annular heating furnace. Background technique [0002] In the steel pipe manufacturing enterprise, to make the steel pipe shape, the steel pipe billet must be heated first, and then the steel pipe can be formed by the forming machine. Because the heating of the steel billet is different from that of other steel billets, the heating accuracy is very high, and all parts of the steel billet are required to be heated evenly, so as to prevent breakage, deformation, and uneven thickness distribution of the steel pipe during the drilling and straightening process. Uniformity, etc., so the traditional pusher type heating furnace cannot be used to heat it, because the heating of the traditional pusher type heating furnace is not very uniform. In the case of the traditional type, it is more heated in the middle, so the ring heating furnace ca...

AI Technical Summary

Problems solved by technology

This kind of annular heating wheel loading and unloading device is still directly operated by the staff. On the one hand, because of manual direct operation, it is easy to cause bumps on the blanks grabbed by the manipulator, which affects product quality.

On the other hand, because the environment at the inlet and outlet of the annular heating furnace is very harsh, with high temperature and large dust, it is generally difficult for the staff to operate there for a long time, especially the operator of the loading and unloading machine at the furnace mouth. If the pressure in the furnace is not well controlled, it may cause the fire to run out, causing the temperature of the furnace mouth to rise sharply, and there may be a danger of scalding the operator. However, due to the limitations of current domestic and foreign technical capabilities, it is difficult to completely control it. The furnace pressure of the heating furnace, so the remote control and automatic control of the loading and unloading machine is a main direction of development today
