Description

Technical Field

[0001] The present application relates to the technical field of raw material preheating equipment, and in particular to a raw material rod heating device for producing iron teeth for track accessories. Background Art

[0002] Currently, if Figure 1 The iron teeth 9 shown are made by heating an iron rod, forging and trimming.

[0003] In the prior art, the iron rod is heated by a high-frequency quenching furnace. This quenching furnace has a fast heating speed, but its principle is to quench the surface of industrial metal parts. It is a metal heat treatment method that generates a certain induced current on the surface of the workpiece, quickly heats the surface of the part, and then quickly quenches it. Induction heating equipment is a device that performs induction heating on the workpiece for surface quenching. The principle of induction heating: the workpiece is placed in an inductor, which is generally a hollow copper tube that inputs medium-frequency or high-frequency alternating current (1000-300000Hz or higher). The alternating magnetic field generates an induced current of the same frequency in the workpiece. The distribution of this induced current in the workpiece is uneven, strong on the surface, very weak inside, and close to 0 in the core. By using this skin effect, the surface of the workpiece can be quickly heated. The surface temperature rises to 800-1000℃ in a few seconds, while the temperature of the core rises very little.

[0004] In order to increase the metal strength of the product, it is urgent to heat the raw material rod as a whole so that the core temperature of the raw material rod is also heated to a certain temperature. Therefore, our company has developed a heating device suitable for the rod body. Utility Model Content

[0026] Reference Figure 2 and Figure 3 A smoke exhaust pipe is connected to the top of one side of the strip-shaped furnace body 1 near the discharge port, a storage trough 6 is arranged on the top of the strip-shaped furnace body 1, the smoke exhaust pipe is connected to the storage trough 6, a feeding port and a smoke extraction port are arranged on the top of the storage trough 6, a discharge trough 7 is connected to the bottom of the storage trough 6, the discharge trough 7 is flat, a feeding assembly 8 is arranged at the feeding port of the strip-shaped furnace body 1, the discharge trough 7 is connected to the feeding assembly 8, and in order to facilitate the rolling of the raw material rods, the inner wall of the bottom of the storage trough 6 is a slope.

[0027] By discharging the tail smoke into the storage tank 6, the high-temperature tail smoke can preheat the raw material rods in the storage tank 6, thereby playing a role in waste smoke utilization and facilitating the subsequent treatment of the tail gas.

[0028] Reference Figure 3 and Figure 5 The feeding assembly 8 includes a receiving trough 81 with an upward opening, the top of which is connected to the discharging trough 7, the width of the inside of the receiving trough 81 can only pass one raw material rod, a clearance groove 811 is provided at the bottom of the receiving trough 81 corresponding to the position of the shifting rod 33, and a clearance opening 812 is provided at the bottom of the receiving trough 81 along the working direction of the strip furnace body 1, and a baffle 82 is provided near the upper side of the clearance opening 812, the baffle 82 is hinged on the receiving trough 81, and a plurality of elastic sheets 83 are fixed on the receiving trough 81, and the elastic sheets 83 can abut against the baffle 82.
