Long aluminum bar heating production line

Abstract

The invention discloses a long aluminum bar heating production line. The long aluminum bar heating production line comprises a feeding mechanism, a transmission device, a heating furnace and a heatingfurnace temperature monitoring device; the feeding mechanism comprises a feeding frame, a pushing rod and a feeding compensating device; the feeding mechanism is connected with the transmission device through the feeding frame; the transmission device is located between the heating furnace and the feeding mechanism, and is right opposite to a furnace body opening of the heating furnace. The production line is provided with the feeding compensating mechanism, and the transmission mechanism is provided with a driving device so that the active material feeding and returning process can be achieved; and the temperature monitoring device is in a direct temperature measuring manner, and a large temperature measuring error is avoided. The long aluminum bar heating production line is used for aluminum profile machining.

Description

technical field [0001] The invention belongs to the technical field of aluminum profile production equipment, in particular to the technical field of aluminum profile production lines. Background technique [0002] The multi-rod furnace is a kind of aluminum rod heating equipment, which can heat the long aluminum rods placed in the heating furnace to the extrusion temperature, and then cut or saw them into short aluminum rods according to the required length of the end face of the aluminum profile, and then Used in feeding extruders. [0003] At present, due to the limitation of the production workshop space, the length of the feeding rack is less than the sum of the distance from the thermal shearing device to the exit of the heating furnace and the length of the aluminum rod, so the remaining material in the aluminum rod heating furnace is insufficient and the feeding mechanism cannot replenish the heating furnace in time Aluminum rods; after the aluminum rods are loaded,...

Problems solved by technology

[0003] At present, due to the limitation of the production workshop space, the length of the loading rack is less than the sum of the distance from the thermal shearing device to the exit of the heating furnace and the length of the aluminum rod, so the remaining material in the aluminum rod heating furnace is insufficient and the feeding mechanism cannot replenish the heating furnace in time Aluminum bar material; after the aluminum bar is loaded, it is necessary to use the transmission mechanism to send the aluminum bar into the heating furnace. The rods are fed into the furnace roller table individually, and then the motor drives the feed roller to make the aluminum rods be sent into the heating furnace. However, the transmission device of the existing aluminum rod heating furnace is hinged with stainless steel rollers and bearings located outside the furnace. It does not have the function of active feeding and returning; the aluminum rod is sent into the heating furnace through the transmission mechanism for heating. During the heating process, it is necessary to measure the temperature of the aluminum rod in the furnace, and the current temperature measurement method of the heating furnace is the heating furnace The temperature measurement method is thermocouple non-contact temperature measurement, and the thermocouple is directly fixed at a given position in the heating furnace.

Using this method to measure the temperature will produce a large error, especially when measuring the temperature of the aluminum rod heated in the furnace, which will directly affect the quality of the aluminum rod
