Heating device for making bending fire curve

Abstract

The invention discloses a heating device for making a bending fire curve. The heating device comprises a base (10), a rotating shaft (20), at least two cantilever rods (30) and a guide plate (50); therotating shaft (20) is fixedly connected to the base (10); the at least two cantilever rods (30) are hinged in sequence and comprise a first connecting end (31) and a second connecting end (32), thefirst connecting end (31) and the second connecting end (32) are arranged end to end, the first connecting end (31) is connected with the rotating shaft (20) in a pivoted mode, and the second connecting end (32) is provided with a fire curve heating head (40); and one end of the guide plate (50) is connected with the rotating shaft (20), the other end of the guide plate (50) is opposite to the second connecting end (32), the guide plate (50) is provided with a guide end face (51), and the second connecting end (32) is suitable for moving along the guide end face (51). The heating device is small in heating range, low in heat energy loss, accurate in fire curve displacement during bending, simple in structure, high in reliability and convenient to operate, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a heating device for making a bending curve. Background technique [0002] In mechanical processing, it is often necessary to bend angle steel, steel plate, etc. During bending, it is necessary to heat the fire curve. The fire curve means that some components on the iron tower need to be bent before they can be installed normally. For example, steel plates, in a certain This position is heated by fire, and then the required angle is completed at a specific position according to the requirements of the process or drawings. This curved position is the fire curve; in the prior art, the general heating methods include open flame, high-frequency heating furnace, etc., but it will The heating range is large, the heat energy loss is large, and the displacement of the fire curve in bending is large. The special heating only heats the fire curve, but it needs to manually control the h...

[0002] In mechanical processing, it is often necessary to bend angle steel, steel plate, etc. During bending, it is necessary to heat the fire curve. The fire curve means that some components on the iron tower need to be bent before they can be installed normally. For example, steel plates, in a certain This position is heated by fire, and then the required angle is completed at a specific position according to the requirements of the process or drawings. This curved position is the fire curve; in the prior art, the general heating methods include open flame, high-frequency heating furnace, etc., but it will The heating range is large, the heat energy loss is large, and the displacement of the fire curve in bending is large.

The special heating only heats the fire curve, but it needs to manually control the heating of the gas cutting torch to the fire curve. First, there are manual deviations in heating, and second, the production efficiency is low.
