Description

Technical Field

[0001] This application relates to the field of aluminum profile processing technology, and specifically discloses a complex cross-section aluminum profile forming equipment. Background Technology

[0002] Aluminum profiles are industrial materials made of aluminum alloy produced through hot extrusion. Due to their excellent properties such as lightweight, corrosion resistance, and easy recyclability, they are widely used in various aspects of life. For example, aluminum profiles are processed into handles and frames for household appliances and automobile bodies; structural components are also common applications of aluminum alloy profiles.

[0003] In the production and processing of aluminum profiles, they need to be processed into aluminum profile products of different shapes and specifications according to the needs of different application scenarios. Under normal circumstances, aluminum profiles of different shapes are extruded by an extrusion press. The principle is to put the aluminum alloy billet into the extrusion press, apply strong pressure through the die cavity, force the metal to undergo directional plastic deformation, and extrude it from the die hole to form a profile with the required cross-sectional shape.

[0004] For aluminum profiles with complex cross-sections, due to their complex end faces, single extrusion can cause problems such as difficulty in demolding and complex structure of processed parts. Therefore, multi-segment continuous extrusion molding is usually adopted. However, for aluminum profiles with multiple protruding ribs, the ribs are difficult to fix during the molding process, which leads to deviations in molding accuracy. Therefore, in view of this, the inventor provides a molding equipment for aluminum profiles with complex cross-sections to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problem that in the traditional process of forming complex cross-section aluminum profiles, the ribs make it difficult to fix the aluminum profiles, resulting in deviations in forming accuracy.

[0006] To achieve the above objectives, the basic solution of this utility model provides a complex cross-section aluminum profile forming equipment, including a worktable, a lifting plate disposed above the worktable, and a lifting cylinder disposed on the worktable and driving the lifting plate to move vertically. The worktable is provided with a first mold, the lifting plate is provided with a forming cylinder, and the piston rod of the forming cylinder is vertically downward and is provided with a second mold adapted to the first mold.

[0007] The workbench is also vertically slidably connected with several fixed blocks that are level with the height of the first mold, and the lifting plate is provided with clamping blocks corresponding to the positions of all the fixed blocks;

[0008] It also includes a drive component for driving the vertical movement of each fixed block.

[0009] The principle and effect of this basic scheme are as follows:

[0010] Compared with the prior art, this utility model sets up multiple fixing blocks and clamping blocks to cooperate, so that during the forming process of aluminum profile, the fixing blocks at different positions contact the aluminum profile with each other, thus avoiding the position of the aluminum profile ribs and clamping the aluminum profile. This makes it easier for the first mold and the second mold to extrude the aluminum alloy, thereby solving the problem that in the traditional forming process of complex cross-section aluminum profiles, the influence of ribs makes it difficult to fix the aluminum profile, resulting in deviations in forming accuracy.

[0011] Furthermore, the drive assembly includes several hydraulic chambers respectively disposed on the worktable, sliding rods slidably connected to each hydraulic chamber, and oil passages for supplying or drawing oil into each hydraulic cylinder. The fixing blocks are respectively disposed on the top of each sliding rod. This arrangement allows the supply or drawing of oil into each hydraulic cylinder to drive the sliding rods to move vertically, thereby causing the fixing blocks to move vertically and come into contact with the aluminum profile.

[0012] Furthermore, the oil circuit includes a main oil pipe and branch oil pipes located between the main oil pipe and each hydraulic chamber. Each branch oil pipe is equipped with an electrically controlled valve. The main oil pipe is connected to an oil tank and is equipped with an oil pump. This configuration facilitates the supply or extraction of oil to each hydraulic cylinder using the drive of the oil pump.

[0013] Furthermore, adjacent fixed blocks are slidably connected. This allows adjacent fixed blocks to guide each other, thereby improving the compactness of the overall structure.

[0014] Furthermore, one side wall of the fixing block is provided with several sliding grooves, and the other side wall of the fixing block is provided with a guide block adapted to the sliding grooves. This arrangement allows the sliding grooves and guide blocks to cooperate, limiting and guiding the relative sliding of the fixing block.

[0015] Furthermore, each of the fixing blocks has a groove on its top, and a pressure sensor is installed in the groove. The pressure sensor is used to detect the pressure when the fixing block contacts the aluminum profile, thereby making it easier to control the movement of each fixing block.

[0020] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0021] The reference numerals in the accompanying drawings include: workbench 1, lifting cylinder 2, lifting plate 3, forming cylinder 4, second mold 5, clamping block 6, aluminum profile 7, base plate 8, base 9, fixing block 10, first mold 11, hydraulic chamber 12, sliding rod 13, sliding piston 14, guide block 15, pressure sensor 16.

[0022] A complex cross-section aluminum profile forming equipment, implementing, for example Figure 1 As shown: It includes a workbench 1, a lifting plate 3 located above the workbench 1, and a lifting cylinder 2 located on the workbench 1 and driving the lifting plate 3 to move vertically. The two lifting cylinders 2 are respectively located on both sides of the workbench 1. The free end of the piston rod of the lifting cylinder 2 is vertically upward and is fixed to the lifting plate 3 through the mounting base, so that the lifting plate 3 is driven to move vertically up and down through the action of the two lifting cylinders 2.

[0023] A base 9 is mounted on the middle of the workbench 1 via an mounting plate. A first mold 11 is mounted on the base 9. A forming cylinder 4 is mounted on the lifting plate 3. The piston rod of the forming cylinder 4 is vertically downward and is equipped with a second mold 5 that is compatible with the first mold 11, so as to perform forming processes such as edge bending and chamfering on the aluminum profile 7.

[0024] like Figure 2 As shown, drive components are evenly arranged on the base 9. Each drive component includes multiple hydraulic chambers 12 and oil pipes for supplying or drawing oil into each hydraulic cylinder. The oil pipes include a main oil pipe and branch oil pipes located between the main oil pipe and each hydraulic chamber 12. Each branch oil pipe is equipped with an electrically controlled valve. The main oil pipe is connected to an oil tank and is equipped with an oil pump. Each hydraulic chamber 12 has a sliding piston 14 slidably sealed at both ends. Each sliding piston 14 is connected to a sliding rod 13. The top of the sliding rod 13 of the same hydraulic chamber 12 extends out of the sliding chamber and connects to the same fixed block 10. Correspondingly, as... Figure 1 As shown, the lifting plate 3 is provided with clamping blocks 6 corresponding to the positions of all the fixing blocks 10.

[0025] like Figure 3 As shown, adjacent fixing blocks 10 are slidably connected to each other. Two sliding grooves are symmetrically provided on one side wall of the fixing block 10, and guide blocks 15 adapted to each sliding groove are symmetrically provided on the other side wall of the fixing block 10. A groove is provided on the top of each fixing block 10, and a pressure sensor 16 is provided in the groove.

[0026] In this embodiment, the controller receives the signal from the pressure sensor 16 and controls the opening and closing of each electrically controlled valve. When the pressure sensor 16 approaches and comes into close contact with the bottom surface or rib of the aluminum profile 7, the pressure on the pressure sensor 16 gradually increases. When the pressure reaches the set threshold, the controller controls the corresponding electrically controlled valve to disconnect.

[0027] After the aluminum profile 7 is placed on the base 9, the lifting cylinder 2 drives the lifting plate 3 to descend, so that the clamping block 6 is tightly attached to the top of the aluminum profile 7. Driven by the oil pump, the fixing blocks 10 are moved upward. The pressure sensor 16 on the fixing block 10 approaches and makes close contact with the bottom surface or ribs of the aluminum profile 7. When the detection value of the pressure sensor 16 reaches the set threshold, the controller controls the corresponding electric valve to disconnect, thus clamping the aluminum profile 7. After clamping, the forming cylinder 4 drives the second mold 5 to move downward. By utilizing the cooperation between the first mold 11 and the second mold 5, the aluminum profile 7 is processed into a suitable shape.

[0028] Compared with the prior art, this utility model sets up multiple fixing blocks 10 to cooperate with clamping blocks 6, so that during the forming process of aluminum profile 7, the fixing blocks 10 at different positions contact the aluminum profile 7, thereby avoiding the position of the ribs of the aluminum profile 7 and clamping the aluminum profile 7. This makes it easier for the first mold 11 and the second mold 5 to extrude and form the aluminum alloy. This solves the problem that in the traditional forming process of complex cross-section aluminum profile 7, the influence of ribs makes it difficult to fix the aluminum profile 7, resulting in deviations in forming accuracy.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
