Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum alloy processing, and particularly relates to an aluminum alloy profile extrusion device. Background Art

[0002] Aluminum alloy extrusion is a manufacturing process used to convert aluminum alloy materials into parts or products with a defined cross-sectional profile.

[0003] First, the aluminum alloy billet needs to be heated to a certain temperature to increase its plasticity and facilitate extrusion; then the extrusion rod begins to push the billet, forcing it to pass through the die fixed at the outlet of the extruder, and then the aluminum alloy billet is formed into the desired shape and size through the die under the pressure of the extrusion rod; finally, the extruded aluminum alloy profile is cut.

[0004] However, since the billet is generally cylindrical, it is very easy for the billet to roll when the extrusion rod pushes the billet, making it impossible for the center of the billet to be aligned with the center of the mold, thereby affecting the quality of the product; and since the billet is heated to a high temperature before extrusion, if the deviated billet is manually corrected, the worker may be burned if the operation is not careful. Therefore, an aluminum alloy profile extrusion device is needed to solve the above problems. Utility Model Content

[0005] The purpose of the present utility model is to provide an aluminum alloy profile extrusion device to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: an aluminum alloy profile extrusion device, comprising:

[0007] work platform;

[0009] Centering components, two of which are provided and symmetrically distributed around the first slide rail;

[0010] The centering assembly includes a moving block, a second slide rail for sliding the moving block, and a clamping block, the second slide rail forms an acute angle with the first slide rail, the moving block is slidably arranged on an end portion of the connecting rod away from the pushing block, the moving block is connected to the clamping block through a telescopic rod at an end portion away from the connecting rod, and a spring is also arranged between the moving block and the clamping block.

[0011] As a preferred solution, the clamping block forms an annular groove on a side facing the first slide rail, which is adapted to the circumferential side of the aluminum alloy billet to be extruded.

[0012] As a preferred solution, the working platform includes a receiving member for placing the aluminum alloy billet to be extruded, and the receiving member is arranged between the pushing block and the first slide rail.

[0013] As a preferred solution, the working platform also includes an extrusion die, which is arranged on the moving track of the pushing block on the first slide rail, and the distance between the first slide rail and the second slide rail gradually decreases in the direction toward the extrusion die.

[0014] As a preferred solution, the working platform also includes a limit block, which is installed on the supporting part. Two limit blocks are provided, and the two limit blocks are symmetrically distributed with the first slide rail as the center. The space formed between the two limit blocks is used to accommodate the aluminum alloy billet to be extruded.

[0015] As a preferred solution, the connecting rod and the telescopic rod are both perpendicular to the first slide rail in the horizontal direction.

[0017] The utility model is provided with a pushing assembly and a centering assembly, wherein the pushing assembly includes a pushing block, a first slide rail and a connecting rod, and the centering assembly includes a moving block, a second slide rail and a clamping block. The centering block and the pushing block are connected by a connecting rod, so that the pushing block drives the two moving blocks to gradually approach each other during the process of pushing the blank, so that the blank is gradually clamped by the two clamping blocks.

[0026] See also Figure 1-4 The utility model provides an aluminum alloy profile extrusion device, comprising:

[0027] Working platform 1;

[0028] The pushing assembly 2 includes a pushing block 21 and a first slide rail 22 for sliding the pushing block 21. The first slide rail 22 is fixedly mounted on the work platform 1. Connecting rods 23 are fixed on opposite sides of the pushing block 21.

[0029] Centering components 3, two centering components 3 are provided and are symmetrically distributed with the first slide rail 22 as the center;

[0030] The centering assembly 3 includes a moving block 31, a second slide rail 32 for sliding the moving block 31, and a clamping block 33. The second slide rail 32 forms an acute angle with the first slide rail 22. The moving block 31 is slidably disposed on the end of the connecting rod 23 away from the push block 21. The moving block 31 is connected to the clamping block 33 at the end away from the connecting rod 23 via a telescopic rod 34. A spring 35 is also provided between the moving block 31 and the clamping block 33.

[0031] The clamping block 33 is formed with an annular groove 331 on a side facing the first slide rail 22 to match the circumferential side of the aluminum alloy billet to be extruded;

[0032] The working platform 1 includes a receiving member 11 for placing the aluminum alloy billet to be extruded, and the receiving member 11 is arranged between the pushing block 21 and the first slide rail 22;

[0033] The working platform 1 further comprises an extrusion die 12, which is arranged on a moving track of a first slide rail 22 by a push block 21, and a distance between the first slide rail 22 and the second slide rail 32 gradually decreases in a direction toward the extrusion die 12;

[0034] The working platform 1 further includes a limit block 13, which is mounted on the receiving member 11. Two limit blocks 13 are provided, and the two limit blocks 13 are symmetrically distributed around the first slide rail 22. The space formed between the two limit blocks 13 is used to accommodate the aluminum alloy billet to be extruded.

[0035] The connecting rod 23 and the telescopic rod 34 are both perpendicular to the first slide rail 22 in the horizontal direction.

[0036] The working principle and use process of this utility model:

[0037] First, the pre-heated and sawn aluminum alloy billet is transferred to the receiving member 11 and placed between the two limit blocks 13. Then, the push block 21 is driven to move on the first slide rail 22 to apply a thrust to the aluminum alloy billet on the receiving member 11, causing the aluminum alloy billet to begin to move toward the extrusion die 12.

[0038] At the same time, since the two moving blocks 31 and the pushing block 21 are connected by the connecting rod 23, the two moving blocks 31 also move on the corresponding second slide rails 32, and since the two second slide rails 32 form an angle with the first slide rail 22, the horizontal distance between the two second slide rails 32 and the first slide rail 22 gradually decreases in the direction toward the extrusion die 12. In this way, the spacing between the two moving blocks 31 also gradually decreases. At the same time, the spacing between the two clamping blocks 33 also gradually decreases. After the annular groove 331 contacts the cylindrical side surface of the aluminum alloy billet, as the pushing block 21 continues to move, the telescopic rod 34 begins to contract, and the spring 35 continues to contract under pressure, thereby achieving the purpose of centering and clamping the aluminum alloy billet between the two limit blocks 13;

[0039] It is worth mentioning that since there are two centering components 3 and they are symmetrical with respect to the first slide rail 22, when the pushing block 21 applies thrust to the aluminum alloy billet, the aluminum alloy billet is always in the middle position of the first slide rail 22. In this way, there is no need for workers to manually straighten the offset aluminum alloy billet, thereby improving the degree of automation of the equipment.

[0040] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
