Fire-blocking apparatus for feeding mechanism of pipe bender

Abstract

A disclosed fire-blocking apparatus for a feeding mechanism of a pipe bender comprises a fire-blocking plate and a fixing plate; the lower end face of the fire-blocking plate pushes down flame erupted by a fire-erupting device below a feeding idler wheel; two lateral sides, facing to a frame, of the fire-blocking plate are both provided with a groove; two edges of the fixing plate are bent for forming bent parts which are stuck by the grooves; the fixing plate is connected with an elevating assembly fixedly disposed on the frame; the elevating assembly comprises a screw and a supporting plate which are cooperated through threaded connection; and the screw passes through a connection plate, and the lower end face of the connection plate abuts against the upper end face of the support plate; and the connection plate is connected with the fixing plate via a supporting rod. According to the fire-blocking apparatus, the height can be momentarily adjusted according to the size of flame of the flame-erupting device, and operation is simple, convenient and relatively safe.

Description

technical field [0001] The invention relates to a fire blocking device for the feeding mechanism of a pipe bending machine. technical background [0002] The energy-saving lamp tube bends the straight tube through a tube bender, and the bending part of the straight tube needs to be heated and softened by a flame spraying device at a local high temperature before bending. The flame spraying device generally uses 5 to 6 oxyacetylene flame spraying heads, and the energy consumption Larger, does not meet the requirements of energy saving and emission reduction. The Chinese invention patent with the publication number CN103663942 discloses a fire baffle device for a U-shaped energy-saving lamp tube bender, which at least includes a fire baffle, and the fire baffle is arranged at the flame injection path of the flame nozzle device on the pipe bender, And the distance between the fire-stop surface on the fire-stop plate and the flame spout on the fire nozzle device is smaller than...

Problems solved by technology

[0003] However, in small and medium-sized production lines, a set of assembly lines is often used to produce different types of lamps, and different types of lamps require different heating temperatures for bending. By scientifically adjusting the flame size of the nozzle, the degree of energy saving and emission reduction can be further improved and production efficiency, but it is troublesome to adjust the height of the above-mentioned fire-stopping device after the flame size of the nozzle is changed, and its housing part will transfer heat to other parts under the high temperature of the flame of the nozzle, which is prone to burn accidents, and the adjustment of the fire-stopping device needs to wait until After each part is cooled, it affects the production efficiency
