Description

Technical Field

[0001] This utility model relates to the field of aluminum rod heating technology, specifically to an aluminum rod heating furnace for aluminum profile production. Background Technology

[0002] Aluminum rod heating furnaces are indispensable equipment in the production of aluminum profiles. They are mainly used to heat aluminum rods to a suitable temperature for subsequent extrusion molding processes. Types include gas-fired furnaces, widely used in large-scale aluminum profile manufacturers with abundant natural gas resources and high production efficiency requirements; resistance furnaces, suitable for smaller-scale manufacturers with high temperature control precision requirements; and induction furnaces, commonly used in high-end aluminum profile manufacturers with extremely high requirements for heating efficiency and temperature uniformity. Regardless of the heating method used, the basic working principle of the furnace is to transfer heat to the aluminum rod through heat transfer, raising its temperature. Specifically, when the furnace starts working, fuel combustion or electric current generates heat through the heating element. This heat is transferred to the aluminum rod through conduction, convection, and radiation, gradually raising the aluminum rod from room temperature to the required extrusion temperature.

[0003] In the prior art, if there is oil on the surface of the aluminum rod, oil fumes will be produced during heating, polluting the environment inside the heating furnace and potentially causing uneven heating. To solve this problem, we propose an aluminum rod heating furnace for aluminum profile production. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figure 1-3 A heating furnace for aluminum rods used in aluminum profile production includes a base 1. A heating furnace body 2 is fixedly connected to the upper end of the base 1. The heating furnace body adopts a double-layer stainless steel structure with heat insulation material in the middle to effectively maintain the stable temperature inside the furnace. A conveyor platform 7 is designed at the heating furnace body 2. The surface of the conveyor platform is specially treated with anti-slip and equipped with an automatic speed adjustment function to adapt to different production rhythms. Multiple aluminum rods are conveyed at the conveyor platform 7. A device seat 6 is set above the conveyor platform 7. The device seat 6 is connected to the outer wall of the heating furnace body 2 through a lifting device. The lifting device is equipped with a digital display screen and can accurately adjust the lifting height to the millimeter level. The lifting device includes a fixed frame 3 fixedly connected to the upper end of the heating furnace body 2. The fixed frame adopts a modular design for easy disassembly and maintenance. A hydraulic rod 4 is fixedly connected through the side wall of the fixed frame 3. The hydraulic rod adopts imported sealing elements and can work at a pressure of up to 20MPa. The extended end of the hydraulic rod 4 is fixedly connected to the upper end of the device seat 6.

[0020] The device base 6 has an arc-shaped groove running through its lower end. The arc-shaped groove is precision CNC machined with a radius accuracy error of no more than 0.05mm. Multiple cleaning rollers 9 are installed inside the arc-shaped groove. Multiple corresponding connecting plates 8 are installed on both sides of the device base 6. The surface of the connecting plates is anodized, which provides excellent corrosion resistance. Multiple connecting plates 8 on one side are fixedly connected to the side wall of the device base 6 using high-strength screws and anti-loosening washers to ensure that they do not loosen during long-term use. Multiple connecting plates 8 on the other side are connected to the side wall of the device base 6 through a connecting device. The connecting device includes a connecting groove running through the inner wall of the arc-shaped groove. The inner wall of the connecting groove is plated with a hard chrome layer, which greatly improves wear resistance and service life. A sliding column is slidably connected inside the connecting groove. The sliding column is made of graphite copper alloy, which has good self-lubricating properties. The sliding column and the inner wall of the connecting groove are elastically connected by a spring 12. The spring is made of 60Si2MnA material and has undergone a special heat treatment process. A positioning post 11 is fixedly connected to the side wall of the connecting plate 8.

[0021] Specifically, multiple connecting plates 8 are respectively set on both sides of each cleaning roller 9, and the distance between the two sides can be adjusted from 50-100mm to meet the needs of aluminum rods of different specifications. A motor 5 is fixedly connected to the side wall of the device base 6. The motor is a servo motor equipped with a reducer and encoder, and the positioning accuracy reaches ±0.01mm. The end of the output shaft of the motor 5 passes through the connecting plate 8 at the corresponding position and is fixedly connected to the side wall of one of the cleaning rollers 9. The output shaft adopts a spline connection to ensure high torque transmission stability. Multiple cleaning rollers 9 are arranged at equal intervals along the wall of the arc groove, and the spacing error is controlled within ±0.1mm to ensure cleaning uniformity. Friction cloth is attached to the side wall of multiple cleaning rollers 9.

[0022] It is worth mentioning that handles 10 are fixedly connected to the side walls of multiple connecting plates 8. The surface of the handles 10 is covered with a non-slip silicone layer and is equipped with an emergency stop button, which conforms to the ergonomic design.

[0023] In this invention, after the aluminum rod, driven forward by the conveyor table 7, moves to the device seat 6, the device seat 6 can fall down. After falling down, the device seat 6 can bring multiple cleaning rollers 9 into contact with the aluminum rod. One of the cleaning rollers 9 is driven to rotate by the motor 5, which can thus bring the aluminum rod in contact to rotate. With the cooperation of multiple cleaning rollers 9, the oil stains can be cleaned.

[0024] When the cleaning roller 9 needs to be replaced, the operator can pull the corresponding connecting plate 8 by the handle 10, so that the corresponding spring 12 will be stretched and deformed, and the positioning post 11 will be disengaged from the positioning groove on the side wall of the cleaning roller 9 to complete the disassembly.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
