Description

Technical Field

[0001] This utility model relates to the field of aluminum extrusion technology, specifically to an aluminum extrusion press with a protective mechanism. Background Technology

[0002] Aluminum profile extrusion is a metal processing technology that extrudes heated and softened aluminum material through a die cavity into a specific cross-sectional shape. It is suitable for producing aluminum profiles with complex structures and high dimensional accuracy requirements. The extrusion process is usually propelled by a hydraulic cylinder installed in the rear frame, which pushes the pusher to drive the die and feed the aluminum material into the die head. The aluminum material is subjected to pressure in the die cavity and the mold cavity, resulting in plastic flow and finally forming a continuous aluminum profile.

[0003] Currently, in common aluminum profile extrusion presses, the aluminum material is positioned manually or by a simple limiting structure before being pushed into the die head. Because the aluminum material is lightweight and has poor rigidity, it is prone to shaking or shifting during the force-driven process. Once the aluminum material shifts, it will not only fail to enter the cavity accurately, but it will also easily cause problems such as uneven force on the die head, profile deformation, and irregular cross-section. At the same time, it will also affect the service life of the die and increase the scrap rate.

[0004] Therefore, there is an urgent need for aluminum extrusion presses with protective mechanisms to address the aforementioned technical deficiencies. Utility Model Content

[0005] The purpose of this invention is to provide an aluminum extrusion press with a protective mechanism to solve the problem mentioned in the background art that aluminum material is prone to swaying or deviating during the force-driven process.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an aluminum product extrusion press with a protective mechanism, comprising a base plate and a front frame, the left side of the base plate being the front frame and the rear side of the base plate being the rear frame, a fixed seat being fixedly connected to the top of the base plate, a support being fixedly connected to the top of the fixed seat, and a protective mechanism being provided inside the support; the protective mechanism includes a wall groove formed in the outer wall of the support, a servo motor being fixedly connected to the bottom of the support, a turntable being fixedly connected upward to the servo motor, push-pull arms being hinged to both sides of the bottom of the turntable, the push-pull arms extending to the outside of the wall groove and being hinged to movable plates respectively, a protective plate being fixedly connected to the top of the movable plate, and guide wheels being installed on the inner sidewalls of the protective plate.

[0007] As a further technical solution of this utility model, the top of the support is machined with a work station, and aluminum material is placed in the work station.

[0008] As a further technical solution of this utility model, the push-pull arms are arranged in parallel, and the turntable is a rhomboid disc.

[0009] As a further technical solution of this utility model, each of the moving plates is welded with a sliding sleeve at its bottom end, and a guide rod is fixedly connected inside the support. The sliding sleeves are respectively sleeved on the outside of the guide rod and move.

[0010] As a further technical solution of this utility model, the protective plate and the movable plate form an "L"-shaped protection, and the two sets of guide wheels are symmetrically distributed about the horizontal center line of the support.

[0011] As a further technical solution of this utility model, a mold cavity is fixedly connected inside the front frame, a mold head is fixedly assembled inside the mold cavity, a cavity is machined inside the mold head, and the aluminum material is aligned with the center of the mold head.

[0012] As a further technical solution of this utility model, a hydraulic cylinder is fixedly connected to the inner wall of the rear frame, a pusher is fixedly connected to the piston end of the hydraulic cylinder, and a pressure mold is fixedly connected to the pusher.

[0013] As a further technical solution of this utility model, four sets of guide pillars are arranged around the oil cylinder, and the pusher is movably sleeved on the outside of the guide pillars.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the aluminum extrusion press with protective mechanism not only prevents the aluminum material from shaking or shifting when it is pushed in the support, but also reduces the tedious steps of dismantling and resetting the protective mechanism, improves the efficiency of batch processing, and achieves stable extrusion effect.

[0015] (1) By setting up a protective mechanism, before the die pushes the aluminum material into the die head, the servo motor drives the turntable to rotate clockwise, and the two sets of push-pull arms pull the protective plate to move relative to each other. When the guide wheel touches the side of the aluminum material, it stops clamping. It can guide and push the aluminum material before it begins to enter the die head, which plays the role of limiting and sliding protection, preventing the aluminum material from shaking or deviating when it is pushed in the support, so that the aluminum material can pass through the cavity smoothly to complete the extrusion. It has the function of protecting the aluminum material from extrusion.

[0016] (2) By setting up a movable plate, the guide wheel can be horizontally guided on the side according to the size of the aluminum material. It can provide a suitable guiding and protective effect for aluminum materials of different specifications, so as to avoid the gap on both sides of the aluminum material being too large or too small due to a single fixed size, thereby improving the guiding stability, reducing the tedious steps of dismantling and resetting the protection, and improving the efficiency of batch processing.

[0017] (3) The mold is equipped with a pusher, guide pillars, hydraulic cylinders, a rear frame, and a die. The hydraulic cylinder is installed at the rear frame. The hydraulic cylinder pushes the die against the aluminum material and pushes the aluminum material into the mold cavity. The guide pillars are distributed around the hydraulic cylinder to limit and guide the movement, ensuring the accuracy of the linear movement of the pusher and avoiding the occurrence of extrusion skew or eccentricity. When the aluminum material passes through the cavity, it will pass through the cavity under the strong extrusion force to complete the extrusion operation. The extrusion effect is stable.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4The present invention provides an embodiment of an aluminum extrusion press with a protective mechanism, comprising a base plate 8 and a front frame 1. The front frame 1 is located on the left side of the base plate 8, and the rear frame 12 is located on the rear side of the base plate 8. A fixed seat 7 is fixedly connected to the top of the base plate 8, and a support 6 is fixedly connected to the top of the fixed seat 7. A protective mechanism is provided inside the support 6. The protective mechanism includes a wall groove 14 formed on the outer wall of the support 6. A servo motor 15 is fixedly connected to the bottom of the support 6. A turntable 20 is fixedly connected upward to the servo motor 15. Push-pull arms 19 are hinged to both sides of the bottom of the turntable 20. The push-pull arms 19 extend to the outside of the wall groove 14 and are respectively hinged to movable plates 18. A protective plate 5 is fixedly connected to the top of the movable plate 18. Guide wheels 22 are installed on the inner sidewalls of the protective plate 5. A workstation 21 is processed at the top of the support 6, and aluminum material 4 is placed in the workstation 21.

[0025] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, before the die 13 pushes the aluminum material 4 into the die head 3, the servo motor 15 drives the turntable 20 to rotate clockwise, and the two sets of push-pull arms 19 pull the protective plate 5 to move relative to each other. When the guide wheel 22 touches the side of the aluminum material 4, it stops clamping. It can guide and push the aluminum material 4 before it begins to enter the die head 3, which plays the role of limiting and sliding protection, preventing the aluminum material 4 from shaking or deviating when it is pushed in the support 6, so that the aluminum material 4 can pass smoothly through the cavity 23 to complete the extrusion.

[0026] The push-pull arms 19 are arranged in parallel, the turntable 20 is a diamond-shaped disc, and the bottom of the moving plate 18 is welded with a sliding sleeve 17. The support 6 is fixedly connected with a guide rod 16, and the sliding sleeve 17 is respectively sleeved on the outside of the guide rod 16 and moves. The protective plate 5 and the moving plate 18 form an "L"-shaped protection. The two sets of guide wheels 22 are symmetrically distributed about the horizontal center line of the support 6.

[0027] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, by means of two sets of movable plates 18 that can move relative to or towards each other, the guide wheel 22 can guide the side of the aluminum material 4 horizontally according to the size of the aluminum material 4. It can provide a suitable guiding and protective effect for aluminum materials 4 of different specifications, so as to avoid the gap on both sides of the aluminum material 4 being too large or too small due to a single fixed size.

[0028] A mold cavity 2 is fixedly connected inside the front frame 1. A mold head 3 is fixedly assembled inside the mold cavity 2. A cavity 23 is machined inside the mold head 3. The aluminum material 4 is aligned with the center of the mold head 3. A hydraulic cylinder 11 is fixedly connected to the inner wall of the rear frame 12. A pusher 9 is fixedly connected to the piston end of the hydraulic cylinder 11. A pressure mold 13 is fixedly connected to the pusher 9. Four sets of guide pillars 10 are arranged around the hydraulic cylinder 11. The pusher 9 is movably sleeved on the outside of the guide pillars 10.

[0029] Specifically, such as Figure 1 and Figure 4As shown, a hydraulic cylinder 11 is installed at the rear frame 12. The hydraulic cylinder 11 pushes the die 13 against the aluminum material 4, pushing the aluminum material 4 into the mold cavity 2. The guide pillars 10 are distributed around the hydraulic cylinder 11, which play a limiting and guiding role, ensuring the accuracy of the linear movement of the push frame 9 and avoiding the occurrence of extrusion skew or eccentricity. When the aluminum material 4 passes through the cavity 23, it will pass through the cavity 23 under the action of strong extrusion force, completing the extrusion operation.

[0030] Working principle: First, the aluminum material 4 is heated to a set temperature to give it a certain degree of plasticity. Before the die 13 pushes the aluminum material 4 into the die head 3, the servo motor 15 drives the turntable 20 to rotate clockwise. The two sets of push-pull arms 19 pull the protective plate 5 to move relative to each other. When the guide wheel 22 touches the side of the aluminum material 4, it stops clamping. It can guide and push the aluminum material 4 before it begins to enter the die head 3, which plays a role in limiting and sliding protection, preventing the aluminum material 4 from shaking or deviating when it is pushed into the support 6. This allows the aluminum material 4 to pass smoothly through the cavity 23 to complete the extrusion. Then, the hydraulic cylinder installed on the inner wall of the rear frame 12... 11 provides thrust, and the die 13 pushes the aluminum material 4 into the die cavity 2. During the pressing process, the aluminum material 4 will gradually form extrusion pressure inside the die head 3 due to the constraint of the cavity 23. During the extrusion process, the front end of the aluminum material 4 first contacts the entrance position of the cavity 23. As the thrust increases, its internal structure begins to rearrange along the internal shape of the cavity 23. The metal material is in a viscous flow state under high pressure and moves forward along the wall of the cavity 23. After shearing, compression, deformation and other stresses, a dense and uniform profile cross section is formed, and finally it is extruded and formed according to the cross section shape of the cavity 23.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
