Pole type workpiece heating furnace

Abstract

The invention discloses a pole type workpiece heating furnace which comprises a furnace body, wherein the front end of the furnace body is provided with a feeding hole, the rear end of the furnace body is provided with a discharging hole, a workpiece platform is arranged in the furnace body, at least two rows of longitudinally arranged stepping beams are arranged in the workpiece platform in a penetrating manner, a stepping mechanism used for driving the stepping beams to step is arranged on the lower part of the furnace body, a fireproof layer is arranged on the periphery of the inner side of the furnace body, a nozzle is arranged on the top of the furnace body, the upper surface of each stepping beam is of a zigzag structure, fireproof bricks are built on the upper surface of the workpiece platform, a discharging platform is arranged on the lower part of the discharging hole, an incline is arranged on the discharging platform, a plurality of discharging clamping plates which are transversely arranged and distributed along the longitudinal direction are arranged on the incline, the discharging clamping plates are hinged on the incline and sinking grooves in which the discharging clamping plates can be turned are arranged on in the incline. The planes of the zigzag structures ensure that stabilizing poles are neatly arranged in the stepping beams or furnace body in a process of conveying into a furnace cavity for heating, therefore, the stabilizing poles can be heated uniformly without easily deforming, the working efficiency can be increased, and the product quality is improved.

Description

technical field [0001] The invention relates to a heating furnace for long rod workpieces. Background technique [0002] The stabilizer bar is an important component in the car suspension. In the current heating furnace for long rod workpieces, the stepping machine structure is generally adopted. The walking beam is an I-beam, and the walking beam and the furnace bottom are both flat. During the heating process, the stabilizing rod is easy to fall into the furnace Rolling causes uneven heating of the stabilizer bar and local deformation of the stabilizer bar, which is not conducive to the thermoforming and quenching process of the stabilizer bar after the heating process; there is also a closed heating furnace for heating, although it can be heated evenly, it is difficult to take materials from the furnace , needs to be manually taken out from the heating furnace, the work efficiency is not high and the optimum quenching temperature of the stabilizer bar is often lost, whic...
