[0004] The above prior art is known through actual use. It mainly extrudes the aluminium alloy plate above the die by moving the extruding plate downward, so that the aluminium alloy plate is attached to the groove in the die to realize shaping. At the same time, the elastic limiting blocks are used to tightly press the two side plates of the aluminium alloy, so as to reduce the displacement of the aluminium alloy plate during extrusion. However, the elastic limiting blocks are used to tightly press the aluminium alloy plate, and the aluminium alloy plate will still deviate to some extent when it is extruded, which will cause inaccurate extrusion of the aluminium alloy plate. Therefore, the above prior art is improved according to the actual use. UTILITY MODEL CONTENTS

[0005] In view of the problem that the elastic limiting blocks are used to tightly press the aluminium alloy plate, and the aluminium alloy plate will still deviate to some extent when it is extruded, which will cause inaccurate extrusion of the aluminium alloy plate, the utility model aims to provide an extruding machine for aluminium alloy processing.

[0006] To achieve the technical purpose, the utility model provides the following scheme: an extruding machine for aluminium alloy processing, which comprises a frame. A movable extruding plate is arranged on the top wall of the frame. A die is arranged on the bottom wall of the frame, and a groove is arranged in the die. A positioning member is arranged on the outer edge of the groove. The positioning member comprises a vertical rod and an elastically movable circular plate.

[0008] Preferably, an electric telescopic rod is fixed to the upper end of the frame by a mounting bracket. The output end of the electric telescopic rod passes through the frame and is fixed to the upper surface of the extrusion plate to drive the extrusion plate to rise and fall. A through groove is provided at the upper end of the extrusion plate.

[0009] Preferably, a limiting rod is integrally provided at the upper end of the extrusion plate, and the upper end of the limiting rod passes through the upper end of the frame.

[0010] Preferably, the upper surface of the mold near the four corners of the outer edge of the groove is welded to the lower end of the upright. The upper surface of the mold is provided with a rectangular groove and a heat-conducting frame is fixed in the rectangular groove by bolts. A heating plate is provided on one side of the heat-conducting frame.

[0011] Preferably, heat-conducting sheets are welded between the inner side of the heat-conducting frame and the outer surface of the upright, and between the outer side of the heat-conducting frame and one side of the heating plate.

[0012] Preferably, a spring is sleeved around the periphery of the upright, the upper end of the spring is welded to the lower surface of the circular piece, and the lower end of the spring is welded to the upper end of the mold; Beneficial effects

[0013] In this utility model, the upright rod in the positioning component passes through the aluminum profile plate, which can position the aluminum profile plate. When the electric telescopic rod is activated and the extrusion plate moves down to extrude the aluminum profile plate above the mold, the aluminum profile plate can be tightly fitted with the groove in the mold without displacement, thus achieving precise shaping and greatly improving the shaping accuracy of the aluminum profile plate.

[0014] After the aluminum profile plate and the upright are fitted together, the bottom of the aluminum profile plate will press against the upper surface of the elastic circular piece. When the extrusion plate presses the aluminum profile plate, the aluminum profile plate will apply pressure to the elastic circular piece to compress the spring. After the aluminum profile plate is shaped, the extrusion plate separates from the mold, and the rebounding spring will push the circular piece to move the aluminum profile plate up and separate it from the mold, thus realizing the rapid and automatic demolding of the aluminum profile plate.

The heat will be transferred to each upright through the heat-conducting plate and frame to heat the aluminum profile plate, thereby preheating the aluminum profile plate. This allows the aluminum profile plate to be formed at a suitable temperature, improving the fluidity of the material and enhancing the shaping quality. Attached Figure Description

[0021] The utility model of this application will be further described in detail below with reference to the accompanying drawings and specific embodiments. In order to provide a clear and complete description of the technical solution, the following embodiments are selected for illustration; other embodiments obtained based on the content described in this application without creative effort are all within the scope of protection of this utility model.

[0022] In the following embodiments, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", "top / bottom" and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the purpose of clearly describing this embodiment, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, and therefore should not be construed as a limitation of this application.

[0023] like Figures 1 to 4 As shown, this embodiment of the invention provides an extrusion press for aluminum profile processing, including a frame 1. An extrusion plate 2 is movably disposed on the top wall of the frame 1, and a mold 3 is disposed on the bottom wall of the frame 1. A groove 4 is disposed inside the mold 3, and a positioning element 5 is disposed on the outer edge of the groove 4. The positioning element 5 includes a copper upright 51 and an elastically movable alloy circular piece 52. The upper end of the upright 51 passes through the aluminum profile plate 11, and the circular piece 52 is sleeved around the upright 51 to support the aluminum profile plate 11 and ensure the stability of the aluminum profile plate 11.

[0024] refer to Figure 2 The bottom wall of the frame 1 is integrally provided with a track 6. The mold 3 can be slidably installed on the outer periphery of the track 6 to enable the mold 3 to be quickly positioned and installed. The mold 3 is provided with a screw 7 with an internal thread, and one end of the screw 7 is pressed against the outer surface of the track 6 to lock the mold 3.

[0025] refer to Figure 1 and Figure 4An electric telescopic rod 10 is fixed to the upper end of frame 1 via a mounting bracket. The output end of the electric telescopic rod 10 passes through frame 1 and is fixed to the upper surface of extrusion plate 2 to drive the extrusion plate 2 to rise and fall. A through groove 8 is provided at the upper end of extrusion plate 2. A limit rod 9 is integrally provided at the upper end of extrusion plate 2 to prevent extrusion plate 2 from shifting. The upper end of the limit rod 9 passes through the upper end of frame 1. The upper surface of mold 3 near the four corners of the outer edge of groove 4 is welded to the lower end of upright rod 51. A rectangular groove is provided on the upper surface of mold 3, and a copper heat-conducting frame 55 is fixed in the rectangular groove by bolts. A heating plate 54 is provided on one side of heat-conducting frame 55. Copper heat-conducting sheets 56 are welded between the inner side of heat-conducting frame 55 and the outer surface of upright rod 51, and between the outer side of heat-conducting frame 55 and one side of heating plate 54. Heating plate 54 is fixed to the upper end of mold 3 by bolts.

[0026] Before the aluminum profile sheet 11 is extruded, it is preheated. The preheating temperature is generally around 400-500℃. This temperature range helps to reduce the deformation resistance of the aluminum profile sheet 11, making it easier to flow during the extrusion process, thereby better filling the groove 4 of the fitting mold 3. This effectively improves the surface quality and dimensional accuracy of the profile.

[0027] During the extrusion process, the temperature is best controlled between 480-520℃. If the temperature is too high, such as exceeding 550℃, it may cause the aluminum profile sheet 11 to overheat, resulting in a decrease in the mechanical properties of the profile and defects such as coarse grains. Conversely, if the temperature is too low, the fluidity of the aluminum profile sheet 11 will decrease, and the extrusion pressure will increase. This will not only affect the service life of the die 3 but also cause quality problems such as cracks and tears on the surface of the aluminum profile sheet 11.

[0028] refer to Figure 3 A spring 53 is sleeved around the outside of the upright 51. The upper end of the spring 53 is welded to the lower surface of the circular piece 52, and the lower end of the spring 53 is welded to the upper end of the mold 3.

[0029] Working principle: The aluminum profile plate 11 needs to have circular through holes at the four corners so that the upright rod 51 in the positioning part 5 can pass through the through holes to position the aluminum profile plate 11. When the electric telescopic rod 10 is activated and the extrusion plate 2 moves down to extrude the aluminum profile plate 11 above the mold 3, the aluminum profile plate 11 can be tightly fitted with the groove 4 in the mold 3 without displacement, thus achieving precise shaping and greatly improving the shaping accuracy of the aluminum profile plate 11.

[0030] After the aluminum profile plate 11 and the upright 51 are fitted together, the bottom of the aluminum profile plate 11 will press against the upper surface of the elastic circular piece 52. When the extrusion plate 2 extrudes the aluminum profile plate 11, the aluminum profile plate 11 will apply pressure to the elastic circular piece 52 to compress the spring 53. After the aluminum profile plate 11 is shaped, the extrusion plate 2 separates from the mold 3. The rebounding spring 53 will push the circular piece 52 to move the aluminum profile plate 11 upward and separate it from the mold 3, thereby realizing the rapid and automatic demolding of the aluminum profile plate 11.

[0031] Before use, the heating plate 54 can be activated to generate heat. The heat will be transferred to each upright 51 through the heat-conducting plate 56 and the heat-conducting frame 55 to heat the aluminum profile plate 11, thereby preheating the aluminum profile plate 11. This allows the aluminum profile plate 11 to be formed at a suitable temperature, improving the fluidity of the material and enhancing the shaping quality.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any minor modifications, equivalent substitutions and improvements made to the above embodiments based on the technical essence of the present utility model should be included within the protection scope of the technical solution of the present utility model.
