Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy casting processing technology, and in particular to an aluminum alloy casting gating cutting device. Background Technology

[0002] In the field of aluminum alloy casting machining, gating cut is a critical process after casting formation, directly affecting the final quality of the casting and the accuracy of subsequent assembly. Traditional aluminum alloy casting gating cut processes suffer from several technical challenges: Firstly, the flexibility of cutting parameter adjustment is insufficient. The cutting blade angle, cutting position, and depth of traditional devices mostly rely on manual adjustment, which is not only cumbersome to operate but also difficult to achieve precise control. It cannot adapt to the processing needs of different specifications and shapes of gatings, especially for non-right-angle or irregularly shaped gatings, where cutting deviations are prone to occur.

[0003] Secondly, the processing safety and environmental control are inadequate. Aluminum alloy shavings generated during the cutting process are prone to flying at high speed, which may pose a risk of scratches to operators and will also scatter into the processing table and equipment gaps, polluting the working environment. At the same time, shavings adhering to the surface of castings or cutting parts may also affect the subsequent cutting accuracy and increase cleaning costs.

[0004] Therefore, in order to meet the requirements of precision, safety and efficiency in the cutting of aluminum alloy castings, there is an urgent need for a special cutting device that integrates multi-dimensional adjustment, waste chip centralized treatment and stable positioning functions.

Combined with the waste chip treatment and safety protection functions of the protective component, it can stably and efficiently complete the cutting of aluminum alloy casting gating. It is suitable for batch processing scenarios of castings of various specifications.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A cutting device for the gating system of an aluminum alloy casting includes a casting support base. The casting support base is rectangular and has several limiting support bars evenly distributed inside it. Two fixed brackets are symmetrically arranged on the upper surface of the casting support base. A top plate is fixedly arranged at the top of the two fixed brackets. A driving mechanism is arranged on the surface of the top plate. A cutting mechanism is arranged at the bottom of the driving mechanism. The cutting mechanism includes a fixed frame, an adjusting threaded rod rotatably connected to the inner side of the fixed frame, an adjusting seat threadedly connected to the surface of the adjusting threaded rod, an adjusting motor fixed to one end of the fixed frame, a rotating shaft of the adjusting motor fixedly connected to the end of the adjusting threaded rod, a positioning shaft rotatably provided on the lower surface of the adjusting seat, a cutting mounting seat fixedly connected to the bottom end of the positioning shaft, a cutting saw blade rotatably connected to the inner side of the cutting mounting seat, and a rotary motor for driving the cutting saw blade provided on the outer side of the cutting mounting seat, and a protective component provided on the surface of the cutting mounting seat; The protective assembly includes an arc-shaped air guide shroud fixedly connected to one side of the cutting mounting base, and an air intake pipe connector is fixedly embedded on the upper surface of the arc-shaped air guide shroud.

[0007] In a preferred embodiment, the arc-shaped flow guide is positioned corresponding to the cutting saw blade, which is located inside the arc-shaped flow guide. The bottom of the arc-shaped flow guide has a waste chip discharge port, and the arc-shaped flow guide is used to discharge waste chips to the bottom of the casting support.

[0008] In a preferred embodiment, the drive mechanism includes a strip-shaped guide shell fixedly connected to the upper surface of the top plate, a drive threaded rod rotatably connected to the inner wall of the strip-shaped guide shell, a movable seat threadedly connected to the surface of the drive threaded rod, and an electric telescopic rod fixedly installed inside the movable seat.

[0009] In a preferred embodiment, the telescopic end of the electric telescopic rod is fixedly connected to a lifting block, the bottom end of the lifting block is fixedly connected to the upper surface of the fixed frame, and the lifting block is slidably connected to the inner wall of the movable seat.

[0010] In a preferred embodiment, the protective assembly further includes an air pump fixedly connected to the side of the movable seat, the output end of the air pump being fixedly connected to an air guide hose, and the end of the air guide hose away from the air pump being fixedly connected to the air inlet end of the air inlet pipe connector.

[0011] In a preferred embodiment, a drive motor is fixedly mounted on the end of the strip-shaped guide shell, and the rotation shaft of the drive motor extends into the interior of the strip-shaped guide shell and is fixedly connected to one end of the drive threaded rod.

[0012] In a preferred embodiment, the top end of the positioning shaft extends into the interior of the adjusting seat and is fixedly connected to a worm gear. A positioning motor is fixedly installed on the outside of the adjusting seat.

The drive mechanism, with its drive motor rotating the drive threaded rod, enables the horizontal movement of the moving base, precisely adjusting the horizontal position of the cutting saw blade. Simultaneously, the electric telescopic rod drives the entire cutting mechanism to rise and fall, adjusting the cutting depth. This multi-dimensional adjustment allows the device to adapt to cutting gating systems of aluminum alloy castings of different specifications and shapes, improving its versatility.

[0015] 2. Ensuring Processing Safety and Environmental Cleanliness: Efficient Waste Collection and Discharge: The cutting saw blade is located inside the arc-shaped guide shroud, which blocks the waste generated during cutting, preventing waste from splashing and causing injury to operators. Simultaneously, an air pump blows air into the arc-shaped guide shroud through a flexible air hose. Combined with the arc-shaped structure of the shroud, waste is guided from the waste discharge port at the bottom to the bottom of the casting support base for convenient centralized collection and treatment. This reduces waste pollution to the processing environment and also lowers the risk of waste adhering to castings or equipment and affecting processing accuracy. Operational Safety Protection: The arc-shaped guide shroud physically shields the cutting saw blade, reducing the possibility of operators directly contacting the high-speed rotating saw blade and improving operational safety.

[0016] 3. Enhanced processing stability: Stable casting positioning: The casting support base has a rectangular frame structure, and the evenly distributed limiting support bars inside can provide stable support and limit the aluminum alloy casting, preventing the casting from shifting during the cutting process and ensuring cutting accuracy.

[0017] 4. Improved Processing Efficiency: Automated Adjustment: Cutting position, angle, and depth can all be automatically adjusted via motors and threaded rods, eliminating the need for manual adjustments, saving adjustment time, and improving cutting preparation efficiency. Continuous Operation Guarantee: Efficient waste removal avoids frequent shutdowns for cleaning due to waste accumulation, ensuring continuous cutting and improving overall processing efficiency.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-4 A cutting device for the gating system of aluminum alloy castings is mainly composed of a casting support base 1, fixed brackets 3, a top plate 4, a drive mechanism 5, a cutting mechanism 6, and protective components 7. The casting support base 1 is a rectangular frame, serving as the basic load-bearing structure of the entire device; several limiting support bars 2 are evenly distributed inside it to place and limit the aluminum alloy casting to be processed. Two fixed brackets 3 are symmetrically fixed to the upper surface of the casting support base 1, and the top ends of the two fixed brackets 3 are connected to the top plate 4, which provides the mounting carrier for the drive mechanism 5. The bottom of the drive mechanism 5 is connected to the cutting mechanism 6, used to drive the cutting mechanism 6 to achieve multi-dimensional movement; the cutting mechanism 6 is equipped with protective components 7 for waste chip handling and safety protection during the cutting process.

[0025] It is worth noting that the drive mechanism 5 includes a strip-shaped guide shell 501, a drive threaded rod 502, a movable seat 503, an electric telescopic rod 504, a lifting block 505, and a drive motor 506. The strip-shaped guide shell 501 is fixed to the upper surface of the top plate 4, and its inner wall is rotatably connected to the drive threaded rod 502. The movable seat 503 is threadedly connected to the surface of the drive threaded rod 502, and the movable seat 503 can move axially along the drive threaded rod 502. The drive motor 506 is fixed to the end of the strip-shaped guide shell 501, and the rotation shaft of the drive motor 506 extends into the interior of the strip-shaped guide shell 501 and is fixedly connected to the end of the drive threaded rod 502. The rotation of the drive motor 506 directly drives the drive threaded rod 502 to rotate.

[0026] It should be further explained that an electric telescopic rod 504 is fixed inside the movable seat 503. The telescopic end of the electric telescopic rod 504 extends downward and connects to the lifting block 505. The bottom end of the lifting block 505 is fixedly connected to the upper surface of the fixed frame 601 in the cutting mechanism 6, and the lifting block 505 is slidably connected to the inner wall of the movable seat 503. When the electric telescopic rod 504 extends or retracts, the lifting block 505 can slide up and down along the inner wall of the movable seat 503, thereby driving the entire cutting mechanism 6 to rise and fall.

[0027] It is worth noting that the cutting mechanism 6 includes a fixed frame 601, an adjusting threaded rod 602, an adjusting seat 603, an adjusting motor 604, a positioning shaft 605, a cutting mounting base 606, a cutting saw blade 607, a rotary motor 608, a worm gear 609, a positioning motor 610, and a worm 611. The top of the fixed frame 601 is fixedly connected to the lifting block 505, and the adjusting threaded rod 602 is rotatably connected to its inner side. The adjusting seat 603 is threadedly connected to the surface of the adjusting threaded rod 602, and the adjusting seat 603 can move along the axial direction of the adjusting threaded rod 602. The adjusting motor 604 is fixed to one end of the fixed frame 601, and the rotating shaft of the adjusting motor 604 is fixedly connected to the end of the adjusting threaded rod 602. The rotation of the adjusting motor 604 can drive the adjusting threaded rod 602 to rotate.

[0028] The lower surface of the adjusting seat 603 is rotatably connected to the positioning shaft 605, which can rotate around its own axis. The bottom end of the positioning shaft 605 is fixed to the cutting mounting seat 606. The inner side of the cutting mounting seat 606 is rotatably connected to the cutting saw blade 607, and the outer side is fixed to the rotary motor 608. The rotating shaft of the rotary motor 608 is fixedly connected to the rotating shaft of the cutting saw blade 607, which is used to drive the cutting saw blade 607 to rotate at high speed to achieve the cutting action.

[0029] It should be further explained that the top end of the positioning shaft 605 extends into the interior of the adjusting seat 603 and is fixedly connected to the worm gear 609; the positioning motor 610 is fixedly fixed to the outside of the adjusting seat 603, and the rotating shaft of the positioning motor 610 extends into the interior of the adjusting seat 603 and is fixedly connected to the worm 611, with the worm 611 meshing with the worm gear 609. When the positioning motor 610 rotates, the worm 611 drives the worm gear 609 to rotate, which in turn drives the cutting mounting seat 606 and the cutting saw blade 607 to rotate synchronously through the positioning shaft 605, thereby realizing the adjustment of the cutting angle.

[0030] It is worth noting that the protective component 7 includes an arc-shaped flow guide 701, an air inlet connector 702, a waste chip discharge port 703, an air pump 704, and an air duct 705. The arc-shaped flow guide 701 is fixed to one side of the cutting mounting base 606, and its position corresponds to the cutting saw blade 607. The cutting saw blade 607 is entirely located inside the arc-shaped flow guide 701, forming a wrap-around protection for the cutting saw blade 607. The air inlet connector 702 is fixedly embedded on the upper surface of the arc-shaped flow guide 701, and a waste chip discharge port 703 is opened at the bottom. The orientation of the waste chip discharge port 703 corresponds to the bottom of the casting support base 1, and it is used to guide the flow of waste chips.

[0031] It should be further explained that the air pump 704 is fixed to the side of the movable base 503, and its output end is connected to the air guide hose 705; the end of the air guide hose 705 away from the air pump 704 is fixedly connected to the air inlet end of the air inlet pipe connector 702, forming an airflow channel. The airflow generated by the air pump 704 can enter the interior of the arc-shaped guide shroud 701 through the air guide hose 705 and the air inlet pipe connector 702. Working principle: 1. Casting placement and positioning: The aluminum alloy casting to be processed is placed on the limiting support bar 2 of the casting support seat 1. The limiting support bar 2 supports and limits the casting to prevent displacement of the casting during the cutting process.

[0032] 2. Cutting position adjustment: Start the drive motor 506, which drives the drive threaded rod 502 to rotate within the strip guide housing 501. The moving seat 503 moves axially along the drive threaded rod 502, thereby driving the cutting mechanism 6 to move synchronously until the cutting saw blade 607 reaches the horizontal cutting starting position of the casting runner. Then, start the adjustment motor 604, which drives the adjustment threaded rod 602 to rotate. The adjustment seat 603 moves along the fixed frame 601 to fine-tune the horizontal position of the cutting saw blade 607 to ensure alignment with the cutting path of the runner.

[0033] 3. Cutting angle adjustment: According to the cutting requirements of the gating system, start the positioning motor 610. The positioning motor 610 drives the worm gear 611 to rotate. The worm gear 611 drives the meshing worm wheel 609 to rotate. The positioning shaft 605 rotates synchronously with the worm wheel 609, thereby driving the cutting mounting base 606 and the cutting saw blade 607 to rotate to the preset angle, thus completing the cutting angle adjustment.

[0034] 4. Cutting Operation: The rotary motor 608 is started, and the cutting saw blade 607 begins to rotate at high speed. Simultaneously, the electric telescopic rod 504 is activated, pushing the lifting block 505 downwards along the inner wall of the moving seat 503. The entire cutting mechanism 6 descends, causing the cutting saw blade 607 to contact the casting runner and begin cutting. During the cutting process, the drive motor 506 continuously drives the cutting saw blade 607 to move horizontally according to the cutting path, completing the cutting of the entire runner.

[0035] 5. Waste chip handling and protection: During cutting, the air pump 704 is started simultaneously. The airflow generated by the air pump 704 enters the arc-shaped guide shroud 701 through the air guide hose 705 and the air inlet pipe connector 702. Since the cutting saw blade 607 is located inside the arc-shaped guide shroud 701, the waste chips generated during cutting are blocked by the arc-shaped guide shroud 701. Under the propulsion of the airflow and the guidance of the arc structure, the waste chips are discharged from the waste chip discharge port 703 and fall to the bottom of the casting support 1, realizing the centralized collection of waste chips.

[0036] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
