Abstract
Description
Technical Field
[0001] This application relates to the field of aluminum profile extrusion press technology, and in particular to a residual shearing mechanism for an aluminum profile extrusion press. Background Technology
[0002] Currently, aluminum profile extrusion presses are industrial equipment that force aluminum alloy billets through a die to form profiles with specific cross-sectional shapes using high temperature and high pressure. The core process involves placing an aluminum rod heated to 400-500℃ into an extrusion cylinder. A hydraulic system drives the extrusion rod to push the aluminum material through the die orifices. After cooling and shaping, complex cross-section aluminum profiles for doors, windows, tracks, radiators, and other applications are obtained. This equipment consists of an extrusion main unit (die, extrusion rod), a hydraulic power system, a heating device, and an auxiliary traction and straightening mechanism. It features high-efficiency forming (extrudes tens of meters in a single pass), high material utilization (waste can be recycled), and flexible die changing, and is widely used in construction, transportation, electronics, and other fields.
[0003] In the existing technology, after the aluminum profile extrusion press extrudes the profile, it is necessary to use a shearing device to shear the extruded residue. The current shearing mainly involves using a shearing rod to push the shearing blade against the extrusion die inlet of the extrusion press to shear the extruded aluminum profile bar residue. After the aluminum profile is sheared, the shearing blade returns to its original position, and then the subsequent aluminum profiles are sheared.
[0004] Regarding the aforementioned technologies, the inventors believe that when the shearing blade is fixed on the shearing rod, it usually drags across the cut surface of the profile during the shearing blade's return stroke, thus affecting the flatness of the extruded profile's cut surface. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a residual shearing mechanism for an aluminum profile extrusion press, which solves the technical problem that when the shearing blade is fixed on the shearing rod, it usually drags to the cut surface of the profile during the shearing blade return, thus affecting the flatness of the sheared surface of the extruded profile.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A residual shearing mechanism for an aluminum profile extrusion press includes: a frame for supporting the residual shearing mechanism; a cutting blade mounted on the frame for cutting aluminum profiles; a drive assembly mounted on the frame for driving the cutting blade to cut the aluminum profiles; and a retraction assembly mounted on the frame for driving the cutting blade to move horizontally.
[0008] Furthermore, the drive assembly includes a drive cylinder mounted on the frame, and one end of the piston rod of the drive cylinder is connected to the cutting blade.
[0009] Furthermore, the retraction assembly includes a retraction cylinder, a lifting rod is provided on the frame, the lifting rod is mounted on the frame, the retraction cylinder is mounted on the lifting rod, a slider is slidably mounted on the lifting rod, a drive cylinder is mounted on the slider, and the piston rod of the retraction cylinder is connected to the slider.
[0010] Furthermore, a connecting rod is provided on the frame, the connecting rod is slidably mounted on the frame, the lifting rod is mounted on the connecting rod, and a connecting spring is provided between the connecting rod and the frame, with both ends of the connecting spring connected to the frame and the lifting rod respectively.

[0012] Furthermore, the frame is provided with a driving gear and a driven gear, the frame is provided with a drive motor, the driving gear is mounted on the drive motor, a conveyor belt is provided between the driving gear and the driven gear, the conveyor belt is sleeved on the driving gear and the driven gear, a rotating shaft is provided on the driven gear, and a cam is mounted on the rotating shaft.

[0014] In summary, this application includes at least one of the following beneficial technical effects for a residual shearing mechanism used in an aluminum profile extrusion press:
[0015] In use, the cutting blade is mounted on the frame, and the drive assembly drives the cutting blade to cut the aluminum profile. After the cutting blade has finished cutting the aluminum profile, the retraction assembly drives the cutting blade to retract. When the cutting blade retracts to the side away from the frame, the drive assembly drives the cutting blade to lift up, and then the retraction assembly drives the cutting blade to reset. Then the next set of aluminum profiles is cut. This reduces the cutting blade from dragging on the cut surface of the aluminum profile when it retracts, thereby improving the flatness of the extruded profile shear surface.
[0016] By setting up a drive cylinder and a retraction cylinder, the cutting knife can be made more convenient for cutting aluminum profiles.
[0017] The drive motor drives the active gear to rotate the driven gear, and the cam on the rotating shaft and the guide rod at one end of the connecting rod slide along the guide groove of the cam, which improves the ease of movement of the cutting blade on the frame. Attached Figure Description

[0022] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0023] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0024] This application discloses a residual shearing mechanism for an aluminum profile extrusion press.
[0025] Reference Figure 1 A residual shearing mechanism for an aluminum profile extrusion press includes a frame 1, on which a cutting blade 11 is mounted. A drive assembly 2 and a retraction assembly 3 are provided on the frame 1. The drive assembly 2 drives the cutting blade 11 to cut the aluminum profile. After the cutting blade 11 cuts the aluminum profile, the retraction assembly 3 drives the cutting blade 11 to retract, thereby reducing the risk of the cutting blade 11 dragging onto the cut surface of the aluminum profile during retraction.
[0026] Reference Figure 2The drive assembly 2 includes a lifting rod 21, which is horizontally positioned. The drive assembly 2 also includes a drive cylinder 22, which is vertically positioned, with a cutting blade 11 mounted on one end of the piston rod of the drive cylinder 22. In use, the drive cylinder 22 drives the cutting blade 11 to cut the aluminum profile. After the drive cylinder 22 has finished cutting the aluminum profile, the cutting blade 11 needs to retract to facilitate subsequent cutting of the aluminum profile.
[0027] To reduce damage to the end face of the aluminum profile when the cutting blade 11 retracts, the retraction assembly 3 includes a retraction cylinder 31, which is mounted on the lifting rod 21. A slider 32 is slidably mounted on the lifting rod 21, and a drive cylinder 22 is vertically mounted on the slider 32. One end of the piston rod of the retraction cylinder 31 is connected to the slider 32. After the cutting blade 11 finishes cutting the aluminum profile, the retraction cylinder 31 drives the cutting blade 11 to slide horizontally away from the aluminum profile. Once the cutting blade 11 is away from the aluminum profile, the drive cylinder 22 drives the cutting blade 11 to rise again, thereby reducing the friction between the cutting blade 11 and the end face of the aluminum profile.
[0028] To improve the efficiency of the cutting blade 11's movement during aluminum profile cutting, the drive assembly 2 also includes a connecting rod 23. The connecting rod 23 is vertically oriented and slides in conjunction with the frame 1 in the vertical direction. A lifting rod 21 is installed at one end of the connecting rod 23 in the vertical direction. During use, as the lifting rod 21 slides on the frame 1, it improves the efficiency of the cutting blade 11's movement towards the aluminum profile. When the cutting blade 11 moves close to the aluminum profile, the drive cylinder 22 drives the cutting blade 11 to cut the aluminum profile. This improves both the cutting efficiency of the cutting blade 11 and the end face finish of the cut aluminum profile.
[0029] To improve the stability of the connecting rod 23 sliding on the frame 1, a connecting spring 231 is provided between the connecting rod 23 and the frame 1. One end of the connecting spring 231 is connected to the frame 1, and the other end is connected to the connecting rod 23. By using the connecting spring 231 to tighten the connecting rod 23 on the frame 1, the stability of the connecting rod 23 sliding on the frame 1 is improved.
[0030] Reference Figure 3 Furthermore, a rotating shaft 24 is rotatably mounted on the frame 1, and a cam 241 is mounted on the rotating shaft 24. During use, the cam 241 rotates with the rotating shaft 24. A guide groove 242 is formed on the cam 241 along its edge. A guide rod 232 is rotatably mounted on the end of the connecting rod 23 furthest from the lifting rod 21. One end of the guide rod 232 is embedded in the guide groove 242 of the cam 241. During use, the guide groove 242 guides the guide rod 232, allowing the connecting rod 23 to rise and fall on the frame 1.
[0031] An adjustment plate 25 is provided on the frame 1. The adjustment plate 25 is rectangular in shape. Furthermore, an adjustment groove 251 is provided on one side of the adjustment plate 25 along its length. In addition, an adjustment bolt 252 is provided on the adjustment plate 25. One end of the adjustment bolt 252 passes through the frame 1 and the adjustment groove 251 in sequence. A nut 253 is threadedly connected to the end of the adjustment bolt 252 that passes through the adjustment plate 25. One end of the nut 253 is pressed against the adjustment plate 25.
[0032] A drive motor 26 is mounted on the adjusting plate 25. A drive gear 261 is mounted on the output shaft of the drive motor 26, and a driven gear 262 is mounted on the rotating shaft 24. A conveyor belt 263 is provided between the drive gear 261 and the driven gear 262, and the conveyor belt 263 is fitted onto the drive gear 261 and the driven gear 262. In use, as the drive gear 261 rotates, the drive gear 261 drives the driven gear 262 to rotate via the conveyor belt 263, and the driven gear 262 drives the rotating shaft 24 to rotate. During use, by adjusting the distance between the adjusting plate 25 and the frame 1, the conveyor belt 263 can be tensioned on the drive gear 261 and the driven gear 262.
[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
