[0002] Aluminum is a light metal, and its compounds are widely distributed in nature. It is the largest type of metal among metal varieties. Aluminum has special chemical and physical properties. It is not only light in weight and strong in texture, but also has good ductility, electrical conductivity, thermal conductivity, heat resistance and nuclear radiation resistance. It is an important basic raw material for the development of the national economy. Aluminum rod is a kind of aluminum product. In the process of aluminum profile production, it is necessary to extrude the heated aluminum rod to obtain profiles of different shapes for subsequent use.

DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0035] See also Figures 1 to 10As shown, an embodiment of the present invention provides a novel aluminum rod extrusion forming device, which specifically includes an extruder 1, a forming mechanism 2 is installed on the extruder 1, a locking mechanism 3 is installed on the forming mechanism 2, a heating mechanism 4 is installed on the forming mechanism 2, a locking mechanism 5 is installed on the heating mechanism 4, a feeding mechanism 6 is installed on the extruder 1, and a collecting mechanism 7 is installed on the extruder 1. In this embodiment, the extruder 1 performs the extrusion forming of the aluminum rod through the cooperation of the forming mechanism 2 and the locking mechanism 3, and the extrusion of products of different shapes according to the needs is achieved through the rotation of the forming mechanism 2, and the switching block is efficient. Through the installation of the heating mechanism 4, the forming machine 2 is preheated, which is convenient for subsequent forming work, and the locking mechanism 5 is convenient for disassembly and maintenance. Through the installation of the feeding mechanism 6, it is convenient to transport and feed the aluminum rod, and the operation is convenient and efficient. Through the installation of the collecting mechanism 7, it is convenient to export and recycle the debris when conveying the aluminum rod, which is convenient for subsequent cleaning. Next, we will give the following detailed technical introduction to the specific structures and functions of the forming mechanism 2, the locking mechanism 3, the heating mechanism 4, the locking mechanism 5, the feeding mechanism 6 and the collecting mechanism 7 in the embodiment of the present invention.

[0036] See also Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 and Fig. 9 As shown, the molding mechanism 2 includes a mounting seat 201, and the mounting seat 201 is mounted at one end of the extruder 1. A groove 203 is provided at the top center line of the mounting seat 201. A rotating block 206 is rotatably connected to the mounting seat 201 through a rotating shaft 204. A motor 205 is mounted on one side of the mounting seat 201, and the output shaft of the motor 205 is connected to one end of the rotating shaft 204. The side wall of the rotating block 206 is provided with three annularly distributed grooves 207, and the three grooves 207 are respectively engaged and connected with the molds 202. One of the molds 202 extends into the groove 203. By installing the mounting seat 201, the rotating block 206 can be connected, and by installing the rotating block 206, the three molds 202 can be connected.

[0037] In this embodiment, with the cooperation of the groove 203, one of the molds 202 can be exposed to the outside, and the aluminum rod is extruded by the extruder 1 so that the aluminum rod enters the groove 203 and collides with the mold 202. With the cooperation of the mold 202, the aluminum rod is extruded into a specific shape. Through the operation of the motor 205, the rotating shaft 204 is driven to a certain angle, and the rotating shaft 204 drives the rotating block 206 to rotate a certain angle, so that the mold 202 on the rotating block 206 is switched. In this way, molds 202 of different shapes can be quickly switched as needed, thereby improving production efficiency.

[0038] To further optimize this embodiment, the groove 203 and the slot 207 are both "U"-shaped structures, and the length of the mold 202 is equal to the width of the rotating block 206. This can stabilize the engagement of the mold 202 and facilitate the mold 202 to be exposed to the outside, so that the aluminum rod can be extruded, and the mold 202 can follow the rotating block 206 to rotate and adjust the position inside the mounting seat 201.

[0039] See also Fig. 9 As shown, the engaging mechanism 3 specifically includes a positioning groove 301. Three positioning grooves 301 distributed in an annular manner are provided on the rotating block 206. The positioning groove 301 is located at the inner midline of the clamping groove 207. The positioning groove 301 is a "U"-shaped structure, and the diameter of the positioning groove 301 is larger than the diameter of the clamping groove 207. Three groups of limiting blocks 302 distributed in an annular manner are installed inside the rotating block 206. Two symmetrically distributed limiting blocks 302 form a group. The limiting blocks 302 are slidably connected to the inside of the rotating block 206 through multiple abutment springs 303. One side of the three groups of limiting blocks 302 extends to the inside of the positioning groove 301, and the cross section of the limiting blocks 302 is a trapezoidal structure.

[0040] In this embodiment, by opening the positioning groove 301, the mold 202 and the internal engagement of the slot 207 are stably achieved, and with the cooperation of the resistance spring 303, the limit block 302 has telescopic sliding, which is beneficial to the engagement of the mold 202. The limit block 302 contracts to install the mold 202, and after the engagement is stable, the limit block 302 resets to limit the mold 202. By pulling the mold 202, the mold 202 resists the limit block 302 to shrink and be disassembled.
