Description

Technical Field

[0001] This invention relates to the field of seamless shearing of metal planar rings, and in particular to a fully automatic seamless shearing device and method for metal planar rings. Background Technology

[0002] Metal ring components (such as bearing rings, gear ring blanks, flange rings, etc.) are key basic components widely used in mechanical equipment, wind power energy, and aerospace fields. Currently, thin-walled planar metal ring components are mostly produced by rolling / rolling strip material into continuous ring-shaped blanks, which are then slit into individual pieces according to pitch. Common slitting methods include hydraulic / mechanical shearing, sawing, and laser / waterjet cutting. However, the above slitting methods have the following drawbacks: (1) The open-type shearing of hydraulic pliers / mechanical pliers is affected by unstable support and positioning, resulting in large slits, obvious double-sided cutting edges, and difficulty in controlling burrs and collapse corners. Furthermore, local compression and springback can lead to a decrease in roundness and end face. In continuous production, "back-pulling / slippage" is also prone to occur, causing miscutting and cycle fluctuations.

[0003] (2) Although laser / water jet can improve the end face to a certain extent, it has high requirements for online clamping and pitch positioning of small cross-section narrow rings. Improper clamping can easily lead to deformation. At the same time, the cut gap is still large, making it difficult to meet the "seamless" requirements of subsequent high sealing scenarios. In addition, the equipment and maintenance costs are high, and the requirements for environment and supporting facilities are strict.

[0004] (3) Existing production lines generally rely on manual feeding, alignment and pitch control. It is difficult to reliably match the single-piece cutting and forming cycle. The material utilization rate and yield rate are greatly affected by human factors, resulting in cycle fluctuation, high labor and time costs, and insufficient consistency and traceability.

[0005] Therefore, there is an urgent need for an automated slitting equipment that can be linked with continuous forming to achieve stable, efficient, and consistent cutting of continuous metal planar rings. This would ensure the roundness and end-face geometric accuracy of the rings while obtaining a "seamless" cut, significantly reducing labor and maintenance costs, and adapting to the rapid switching and continuous production of rings of various specifications. Summary of the Invention

[0006] This invention provides a fully automatic seamless shearing device and method for planar metal rings, which solves the problems of large shearing kerf, low shearing efficiency, reduced roundness and high labor costs in traditional planar metal ring shearing.

[0007] To achieve the above objectives, the present invention provides the following solution: The present invention provides a fully automatic seamless shearing device and method for metal planar rings, comprising: The machine frame (1) includes a storage mechanism, a feeding mechanism, a shearing mechanism, and a detection mechanism. The storage mechanism is located above the cylindrical support column of the machine frame, the feeding mechanism is spirally positioned on the cylindrical support column of the machine frame, and the shearing mechanism and the detection mechanism are arranged longitudinally along the generatrix of the cylindrical support column of the machine frame.

[0008] Furthermore, in the storage mechanism, a turntable (2) with a circular groove is placed above the storage motor (7), and a three-jaw chuck (3) is placed inside the turntable to support the stacked continuous metal rings (4). The three-jaw chuck (3) is connected to the storage motor (7) at the bottom of the frame. The bottom of the circular groove of the turntable (2) has a tape outlet with a slope. The storage motor (7) drives the three-jaw chuck (3) to rotate, and the continuous rings are fed into the feeding mechanism at a constant speed from the slope outlet.

[0009] Furthermore, in the feeding mechanism, a set of feeding pulleys (9) are placed on a spiral track (10) and arranged before and after the shearing groove. They drive the continuous metal ring (4) to feed along the spiral track (10) and press the continuous metal ring (4) into the spiral track (10) to prevent the continuous metal ring (4) from leaving the spiral track (10). The pulleys (9) are driven by a pulley motor (8). A cutting groove is provided at a pitch directly above the exit end of the spiral track (10). A pressing plane is provided at the end of the cutting groove to press the continuous metal ring (4) during cutting, so as to avoid the continuous metal ring (4) from "pulling back" and "dragging" during cutting, and improve cutting stability.

[0010] Furthermore, the shearing mechanism is divided into a material stop assembly and a cutting tool assembly; The baffle assembly is placed at the outlet end of the spiral track (10) and consists of a baffle cylinder (5) and a baffle block (6) to prevent the continuous metal ring (4) from sliding along the spiral track (10) during shearing; The cutting tool assembly is positioned directly above the stop assembly, at a distance of one pitch from the stop assembly along the spiral track (10). One end of the cutting tool clamping block (12) is connected to the cutting tool cylinder (11). The cutting tool clamping block (12) has two long bolts (16) with compression springs (13) through it. The two long bolts (16) are respectively connected to the cutting tool front pressure block (14) and the cutting tool rear pressure block (17). The cutting tool (15) is clamped at the bottom of the cutting tool clamping block (12). The cutting tool front pressure block (14) is a sloped wedge-shaped block with the same slope as the spiral track (10); The bottom surface of the tool rear pressure block (17) is a plane, which can fit against the pressing plane at the end of the tool shearing groove; The cutting tool front pressure block (14) and cutting tool rear pressure block (17) work together with the spiral track (10) to press the continuous metal ring (4) at the entrance and end of the shearing groove respectively during shearing, so as to prevent the continuous metal ring (4) from being "pulled back" or "dragged" during shearing, which would cause the ring to break.

[0011] Furthermore, the detection mechanism is a pressure sensor, which is placed on the side of the material blocking assembly that contacts the continuous metal ring. When the continuous metal ring (4) reaches the outlet end of the spiral track (10), the pressure sensor is triggered, and the material blocking assembly descends to the stop position.

[0012] This invention also provides a method for fully automatic seamless cutting of metal planar rings, which, using the aforementioned fully automatic seamless cutting device for metal planar rings, includes the following steps: S1: The storage motor (7) rotates, and the continuous metal ring (4) is fed from the storage mechanism to the feeding mechanism; S2: The continuous metal ring (4) enters the spiral track (10), and a set of pulleys (9) arranged on the spiral track (10) works to drive the continuous metal ring (4) to feed along the spiral track (10); S3: When the continuous metal ring (4) reaches the exit end of the spiral track (10), the pressure sensor is triggered, the storage mechanism and the feeding mechanism stop running, the tool assembly presses the continuous metal ring (4) at the inlet and outlet of the tool shearing groove, and the tool (15) cuts off the continuous metal ring (4). S4: The cutting tool assembly rises, and the storage and feeding mechanisms continue to operate, resulting in the cut metal ring. S5: Repeat the S1-S4 process.

[0013] Compared with the prior art, the present invention has the following advantages and technical effects: The shearing groove at the exit of the spiral track works in conjunction with the end clamping plane to achieve surface pressure stability constraint at the moment of shearing, significantly reducing the kerf gap and double edge, and reducing burrs and corner collapse; at the same time, it suppresses local springback and attitude deviation, and maintains the roundness and end face of the ring.

[0014] The material storage turntable feeds material at a uniform speed, and the spiral guide feed, together with the material blocking component and pressure sensor to trigger the arrival, forms a closed-loop control of "arrival-pressing-shearing-resetting", reducing empty shearing / mis-shearing; it realizes continuous single-piece cutting and synchronous forming cycle, significantly reducing labor and time costs.
