Description

Technical Field

[0001] The utility model relates to the technical field of aluminum bar heating furnaces, and particularly relates to a preheating device for an aluminum bar heating furnace. Background Technique

[0002] Aluminum bar heating refers to the heating process of aluminum bars before forging and extrusion. Usually, an aluminum bar heating furnace is used for heating. The heating temperature can reach up to 650 °C, and the rated operating temperature is 550 °C, which can ensure uniform through-heating of aluminum bars before forging and extrusion. Moreover, the aluminum bar heating furnace has the characteristics of fast heating speed, stable continuous production, and simple and easy maintenance.

[0003] Most of the existing aluminum bar heating furnaces directly heat the aluminum bars without a preheating process, which easily causes the aluminum bars to break suddenly during the processing due to sudden heating, affecting the subsequent forging and extrusion processes. Moreover, when the aluminum bars are directly heated, the temperature change range is relatively large, and the heating time needs to be increased, which easily affects the heating efficiency of the aluminum bars and is rather inconvenient. In the prior art, it is not convenient to preheat multiple aluminum bars at the same time, and usually, the aluminum bars are not transported and loaded manually, and the degree of automation is relatively low. Therefore, we have developed an aluminum bar heating furnace for aluminum profile processing. Content of the Utility Model

[0004] The purpose of the utility model is to provide a preheating device for an aluminum bar heating furnace, which is not only convenient for preheating multiple aluminum bars, but also can automatically transport and load the aluminum bars, and has a relatively high degree of automation, so as to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution:

[0006] A preheating device for an aluminum bar heating furnace, including a preheating furnace body. A preheating chamber is arranged inside the preheating furnace body. The preheating chamber is inclined to one side. Multiple aluminum bars are arranged inside the preheating chamber. An aluminum bar inlet is arranged at the upper end of the preheating chamber. An aluminum bar outlet is arranged at one side of the lower end of the preheating chamber. The aluminum bar outlet corresponds to the feeding port of the heating furnace in position. A through hole is arranged at the other side of the lower end of the preheating chamber. A box body is arranged at the position of the preheating furnace body on one side of the through hole. A jacking mechanism for easily jacking out the aluminum bars is arranged inside the box body.

[0007] Further, the jacking mechanism includes a motor and a jacking rod. The motor is fixedly arranged inside the box body. A turntable is fixedly arranged at the output end of the motor. A strip-shaped frame is arranged above the turntable. A guiding block is slidably arranged inside the strip-shaped frame. The lower end of the guiding block is fixedly connected to the upper edge of the turntable. The jacking rod is slidably arranged inside the through hole. A sliding hole matching with the jacking rod is arranged on the side wall of the box body. One end of the jacking rod is fixedly connected to the strip-shaped frame.

[0008] Further, a circular stopper is fixedly provided at the upper end of the guiding block.

[0009] Further, the diameter of the circular stopper is larger than that of the guiding block.

[0010] Further, sliding sleeves are fixedly provided at both ends of the strip-shaped frame. A sliding rod is slidably arranged inside the sliding sleeve, and both ends of the sliding rod are fixedly connected to the box body.

[0011] Further, a buffer plate is provided on the lower side wall of the preheating chamber. Springs are provided between the four corners of the buffer plate and the side wall of the preheating chamber.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] For the preheating device of the aluminum bar heating furnace, by providing a preheating furnace body, aluminum bars, a box body, a top rod, a circular stopper, a guiding block, a strip-shaped frame, a turntable, a sliding rod, a motor, a sliding sleeve, a preheating chamber, springs, a buffer plate, an aluminum bar outlet, and an aluminum bar inlet, multiple aluminum bars are placed into the preheating chamber through the aluminum bar inlet. When the aluminum bars roll to the bottom of the preheating chamber, they hit the buffer plate. The buffer plate squeezes the springs to provide buffering for the aluminum bars. Start the motor, and the output end of the motor drives the turntable to rotate. When the turntable rotates, it drives the guiding block to rotate. While the guiding block rotates around the motor, it reciprocates within the strip-shaped frame. The guiding block drives the strip-shaped frame to reciprocate, and the strip-shaped frame drives the top rod to reciprocate. The top rod continuously ejects multiple aluminum bars out of the preheating chamber through the aluminum bar outlet. Since the position of the aluminum bar outlet corresponds to the feed inlet of the heating furnace, the aluminum bars directly slide into the heating furnace. This not only facilitates the preheating of multiple aluminum bars but also can automatically convey and feed the aluminum bars, with a relatively high degree of automation.
