Description

Technical Field

[0001] This invention relates to the field of metal processing technology, specifically to a cutting and separating device for the gate of a metal die casting. Background Technology

[0002] After metal die casting is formed, the casting body is connected to the gating system through the gate, which needs to be removed to obtain the finished casting. Currently, commonly used gate removal methods include manual knocking, punching, and mechanical sawing. Manual knocking is inefficient, labor-intensive, and easily damages the casting body; punching is more efficient, but it is suitable for specific shapes and lacks flexibility; mechanical sawing is widely used due to its adaptability, but existing cutting equipment still has the following shortcomings in practical use.

[0003] First, the ability to adjust the cutting posture is limited. Metal die castings come in various shapes, and the location and angle of the gates vary. The cutting blades of existing equipment can usually only feed in a fixed direction, making it difficult to perform multi-angle displacement cutting around the casting. The processing efficiency for castings with multiple gates on complex structures is low, often requiring multiple clamping or manual assistance to flip the casting.

[0004] Secondly, there is insufficient protection for the casting body during the cutting process. The high-temperature chips and flying debris generated during cutting can easily impact the surface of the casting, causing scratches or heat-affected zones. At the same time, if the cut-off gate head falls directly, it not only poses a safety hazard but also makes it difficult to collect and recycle waste.

[0005] Third, the coordination between conveying and cutting is not high. Most equipment requires manual handling to move castings to the cutting station for positioning and fixing, making it difficult to achieve continuous assembly line operation and affecting overall production efficiency.

[0006] Therefore, there is an urgent need for a gate cutting and separation device that can flexibly adjust the cutting posture, effectively protect the casting body, automatically collect gate waste, and realize assembly line transportation, so as to improve the efficiency and quality of post-processing of metal die castings.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1.

By setting up a flexible deflection mechanism, a rotating retaining ring mechanism and a material discharge baffle mechanism, the material discharge baffle can fit against the outer surface of the casting and form a protective barrier for the casting body during cutting to prevent the cutting chips from splashing and scratching the casting. At the same time, the material discharge baffle can collect and guide the cut-off gate material head to a designated collection area to avoid the gate splashing directly and causing safety hazards and waste.

[0019] 4. The flexible deflection mechanism, through the telescopic cooperation of the internal elastic element and slide bar, combined with the rotation of the deflection seat, enables the rotating retaining ring mechanism to adaptively conform to the outer surface of castings with different inclination angles and contours, thereby improving the versatility and fit of the protection and collection mechanism.

[0020] 5. The conveyor system uses a conveyor belt to achieve continuous conveying of metal die-casting parts. In conjunction with the first linear motors symmetrically arranged on both sides and the upper cutting mechanism, it can realize continuous automated operation of cutting, protection and collection, and improve the overall production efficiency.

[0036] The rotating retaining ring mechanism 7 includes an outer ring 701 fixedly connected to the deflection rod 608, an inner ring 702 rotatably connected to the inner side of the outer ring 701, a gear ring 703 fixedly connected to the outer side of the inner ring 702, a motor base 704 fixedly connected to the outer side of the outer ring 701, a fifth motor 705 provided on the motor base 704, a gear 706 fixedly connected to the output shaft of the fifth motor 705, the gear 706 and the gear ring 703 meshing, the inner ring 702 has N first threaded through holes 707 vertically, and the outer ring 701 has N second threaded through holes 708 vertically. The material discharge baffle mechanism 8 includes a first mounting sleeve 801, on which a first bolt 802 is provided. The first bolt 802 passes through the first mounting sleeve 801 and is threadedly connected to a first threaded through hole 707. A material discharge baffle 803 is rotatably connected to the outer side of the first mounting sleeve 801. The material discharge baffle 803 is rotatably connected to a displacement shaft 804.

A second bolt 807 is provided on the second mounting sleeve 806 and passes through the second mounting sleeve 806. The second bolt 807 is threadedly connected to a second threaded through hole 708.

[0037] Specifically, the blanking baffle mechanism 8 includes a first mounting sleeve 801. The lower end of the first mounting sleeve 801 is inserted into the corresponding first threaded through hole 707 on the inner ring 702 and fixed by screwing the first bolt 802 into the first threaded through hole 707. The outer side of the first mounting sleeve 801 is rotatably connected to a blanking baffle 803 via a hinge pin. The blanking baffle 803 is an arc-shaped plate used to conform to the outer surface of the casting and catch the cut-off gate. A displacement shaft 804 is rotatably connected to the blanking baffle 803. The displacement shaft 804 is rotatably connected to a displacement rod 805. The other end of the displacement rod 805 is rotatably connected to a second mounting sleeve 806. The lower end of the second mounting sleeve 806 is inserted into the corresponding second threaded through hole 708 on the outer ring 701 and fixed by screwing the second bolt 807 into the second threaded through hole 708. When the inner ring 702 rotates relative to the outer ring 701, the circumferential relative position between the first mounting sleeve 801 and the second mounting sleeve 806 changes. The displacement rod 805 pushes and pulls the discharge baffle 803, causing it to rotate around the hinge point on the first mounting sleeve 801, thereby adjusting the inclination angle of the discharge baffle 803 to accommodate castings with different profiles or to adjust the collection angle.

[0038] The placement and conveying mechanism 9 includes four supporting side plates 901 fixed on the fixed base plate 1. The top of the supporting side plates 901 is fixedly connected to a bearing plate 902. The bearing plate 902 is provided with two symmetrically arranged conveyor wheel grooves 903. A conveyor wheel 904 is rotatably connected to the bearing plate 902 within the conveyor wheel grooves 903. A conveyor belt 905 is connected between the two conveyor wheels 904. A sixth motor 906 is provided on the side of the bearing plate 902. The output shaft of the sixth motor 906 is coaxially fixedly connected to one of the conveyor wheels 904.

[0039] The workflow of this invention is as follows: I. Casting Conveying and Identification Positioning Stage The die-cast metal part enters the conveyor belt 905 of the conveying mechanism 9 from the previous process. The sixth motor 906 starts, driving the conveyor wheel 904 to rotate and the conveyor belt 905 to transport the casting to the cutting station. After the casting arrives at the station, the conveyor belt 905 stops. The vision sensor at the bottom of the lifting plate 202 scans and identifies the gate on the casting, obtaining the spatial position and height information of the gate. The control system plans the cutting path based on this information.

[0040] II. Protection and Collection Agency in Placement Phase The first linear motors 5 on both sides start synchronously according to the height of the casting, driving the flexible deflection mechanism 6 to rise and fall, so that the rotating retaining ring mechanism 7 reaches the appropriate position above the casting. If there is an inclination angle on the outer surface of the casting, when the material discharge baffle mechanism 8 contacts the surface of the casting, the deflection rod 608 can rotate adaptively around the deflection axis 607. At the same time, the slide rod 604 extends and retracts in the adjusting sleeve 601 and compresses or releases the elastic element 602, so that the rotating retaining ring mechanism 7 fits the outer contour of the casting as a whole.

[0041] The fifth motor 705 starts, driving the gear ring 703 to rotate via the gear 706, which in turn causes the inner ring 702 to rotate relative to the outer ring 701. When the inner ring 702 rotates, a circumferential displacement occurs between the first mounting sleeve 801 fixed thereon and the second mounting sleeve 806 fixed on the outer ring 701. This displacement is achieved by pushing and pulling the material discharge baffle 803 around the hinge point on the first mounting sleeve 801 via the displacement rod 805, adjusting the inclination angle of each material discharge baffle 803 so that it fits tightly against the outer surface of the casting, forming a protective barrier and a gate collection channel.

[0042] III. Automatic Gate Cutting Stage The second linear motor 201 of the lifting adjustment mechanism 2 is started, driving the lifting plate 202 to rise and fall, which in turn drives the rotary displacement mechanism 3 and the displacement cutting mechanism 4 to reach the target cutting height.

[0043] At the start of cutting, the motors of the displacement cutting mechanism 4 work in tandem based on the gate position information provided by the vision sensor. The first motor 301 drives the displacement shaft 302 to rotate, causing the entire displacement cutting mechanism 4 to rotate and shift around the casting, aligning the cutting blade 409 with the gate. The second motor 402 drives the first threaded rod 403 to rotate, causing the vertical mounting frame 404 to move horizontally along the transverse mounting frame 401, achieving radial feed. The third motor 405 drives the second threaded rod 406 to rotate, causing the vertical lifting block 407 to move vertically along the vertical mounting frame 404, achieving depth feed. The fourth motor 408 drives the cutting blade 409 to rotate at high speed, cutting and separating the gate. Under multi-axis linkage, the cutting blade 409 can continuously cut multiple gates around the casting.

[0044] The chips generated during the cutting process are blocked by the material discharge baffle 803 and will not splash onto the surface of the casting body.

[0045] IV. Waste Collection and Discharge Stage The cut-off gate material head falls onto the lower material drop baffle 803 and slides down the plate surface into the designated waste collection container, achieving automatic collection.

[0046] After cutting is completed, the motors of the displacement cutting mechanism 4 reverse their rotation, and the cutting blade 409 exits the cutting area and returns to its initial position. The second linear motor 201 drives the lifting plate 202 to rise, causing the displacement cutting mechanism 4 to detach from the working area above the casting. The first linear motors 5 on both sides drive the flexible deflection mechanism 6 to rise, causing the rotating retaining ring mechanism 7 and the material dropping baffle mechanism 8 to detach from the casting. The sixth motor 906 starts again, and the conveyor belt 905 sends the metal die casting with the gate cut completed out of the cutting station, while simultaneously conveying the next casting to be processed to the station, starting the next work cycle.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
