Abstract
Description
Technical Field
[0001] The present invention relates to the field of conical roll rolling, and in particular to a device and method for assisting in rolling metal rings with equal thickness of conical rolls. Background Art
[0002] Metal ring parts (such as bearing rings, gear ring blanks, flange rings, etc.) are key basic components and are widely used in the fields of mechanical equipment, wind power energy, and aerospace. Generally, the blanking process or conical roll rolling process is used to produce thin-walled metal rings with a high diameter-thickness ratio. However, the traditional blanking process and conical roll rolling process have the following defects: 1. The blanking process requires first rolling the material to the required thickness, then performing stamping and cutting, melting the remaining waste into plates, rolling the plates to the required thickness again, and then performing stamping and cutting. The production process is complex and the material utilization rate is low; 2. According to different required product specifications, corresponding blanking dies need to be designed, which increases the production cost; 3. In the conical roll rolling process, since the contact area between the conical roll and the strip is a non-linear conical surface engagement, the coupling of the radial and axial components of the rolling force easily induces axial movement of the ring, resulting in phenomena such as tail whipping, wrinkling, and non-ring formation; 4. In the conical roll rolling process, since the ring is prone to axial movement in the roll gap and the roll gap thickness is unstable, the circularity of the formed ring is poor. Summary of the Invention
[0003] The present invention provides a device and method for assisting in rolling metal rings with equal thickness of conical rolls, which are used to solve problems such as tail whipping of the strip, low ring forming accuracy, and insufficient material utilization rate existing in the traditional process.
[0004] To achieve the above object, the present invention provides the following solutions: The present invention provides a device and method for assisting in rolling metal rings with equal thickness of conical rolls, including: A rear tension mechanism, a material receiving mechanism, and a frame (19), which are arranged on a bottom plate (7); A conical roll (20) and an inlet and outlet limit adjustment mechanism, which are arranged on the frame (19); The rear tension mechanism and the inlet and outlet limit adjustment mechanism can adjust their positions so that the strip is in the same straight line and at the same height before entering the roll gap.
[0005] Further, the rear tension mechanism assembly includes: A set of slide rails (6), which are fixed on the bottom plate (7) and are used for position adjustment of the rear tension mechanism; A rear tension frame (1), which is equipped with a set of bearing seats with bearings (2) and a tension shaft; One end of the tension shaft is equipped with a feeding disk (4) and a handwheel (5). The handwheel (5) presses against the feeding disk (4) to provide a fastening force for the feeding disk (4). The other end of the tension shaft is connected to an FZ-6-K type magnetic powder controller (3). The FZ-6-K type magnetic powder controller (3) cooperates with a KTC800A type tension controller to provide tension for the device in a constant current mode. The tension provided by the tension mechanism is as follows: Where: F is the tension (unit: N), M is the torque provided by the tension controller (unit: ), R is the diameter of the feeding disk (unit: m), and I is the current input to the tension controller (unit: A).
[0006] Further, the inlet and outlet limit adjustment mechanism includes: An inlet butterfly cover plate (9), an inlet wedge-shaped tunnel plate (8), an inlet middle connecting plate (18), an XY fine adjustment platform (14), an inlet bottom connecting plate (17), a frame connecting plate (12), an outlet channel cover plate (10), an outlet channel base (11), an outlet rotating platform (16), an outlet middle connecting plate (13), and an outlet bottom connecting plate (15); The inlet butterfly cover plate (9) and the inlet wedge-shaped tunnel plate (8) together form a strip inlet channel to provide four-directional limit constraints on the strip in the up, down, left, and right directions. The small end is wedge-shaped along the thickness and width directions, enabling the outlet end of the device to be closer to the inlet end of the cone roll gap, avoiding the phenomenon of the strip tailing off; The inlet middle connecting plate (18) has a 5×5 countersunk thread and through-hole array for connecting the inlet wedge-shaped tunnel plate (8) and the XY fine adjustment platform (14); The connection between the inlet wedge-shaped tunnel plate (8) and the XY fine adjustment platform (14) mates with the countersunk threads and through-holes at different positions on the inlet middle connecting plate (18) to achieve rough adjustment of the position of the inlet limit adjustment mechanism; The two screw knobs of the XY fine adjustment platform (14) can achieve fine adjustment of the position of the inlet limit adjustment mechanism with an accuracy of up to 0.001 mm. The fastening knobs on both sides can fix the XY fine adjustment platform (14) after the position is adjusted.
[0007] Further, it also includes: The cone angle of the cone roll (20) The diameter of the cone tail The upper and lower cone rolls are arranged symmetrically, parallel, and coplanar along the generatrix of the cone roll to form a uniform and equal-thickness roll gap. The frame connecting plate (12) is at an angle of 49° to the horizontal plane and is symmetrically distributed, perpendicular to the central axis of the cone roll; The inlet bottom connecting plate (17) and the outlet bottom connecting plate (15) are placed horizontally, and one end is connected to the frame connecting plate (12).
[0008] Furthermore, it also includes: The channel inlet sides of the outlet channel cover plate (10) and the outlet channel base (11) are wedge-shaped in the thickness direction, so that the inlet ends of the outlet channel cover plate (10) and the outlet channel base (11) extend into the outlet end of the conical roll gap. The channel inlet of the outlet channel cover plate (10) and the outlet channel base (11) is slightly higher than the channel outlet, the included angle between the channel profile projection line and the horizontal line is 3°, the channel has a downward trend, reducing the frictional force generated by gravity of the formed ring in the channel, and also preventing the strip from bending at the channel outlet due to the influence of gravity, thereby improving the stability of the strip in the roll gap. The channel of the outlet channel cover plate (10) and the outlet channel base (11) is a perfect circle, the channel width is 0.5 - 1 mm larger than the width of the metal ring, the center of the channel is located on the extension line of the symmetry line of the two conical roll gaps, and its radius is consistent with the designed radius of the metal ring.
[0009] Furthermore, it also includes: The outlet rotating platform (16) has multiple specifications of counterbores and threaded holes, connecting the outlet channel base (11) and the outlet middle connecting plate (13), and is also used for the rotation and fixation of the outlet channel cover plate (10) and the outlet channel base (11). The outlet middle connecting plate (13) is provided with a 3×3 threaded hole array for connecting with the XY fine adjustment platform (14), and its interface with the outlet rotating platform (16) is designed with a circular contour, so that the outlet middle connecting plate (13) is far away from the conical roll (20), preventing interference between the outlet middle connecting plate (13) and the conical roll when the XY fine adjustment platform works. The outlet bottom connecting plate (15) has a 3×4 threaded hole array, and the XY fine adjustment platform realizes the rough adjustment of the position of the outlet limit adjustment mechanism by connecting with different threaded holes of the outlet bottom connecting plate (15).
[0010] Furthermore, the receiving mechanism includes: The receiving tray (21), the receiving frame (22) and the motor (23) are arranged on the bottom plate (7). The receiving tray (21) is of a disc-shaped structure, connected to the motor (23) through a coupling, and the motor drives the receiving tray to rotate synchronously with the rolling process. The motor speed can be adjusted steplessly to match the discharging speed of the conical roll, preventing the accumulation of the formed rings from hindering the subsequent production.
[0011] The present invention also provides a method for assisting the equal-thickness roll gap rolling of a metal ring by a conical roll, applying the device for assisting the equal-thickness roll gap rolling of a metal ring by a conical roll, including the following steps: S1: Pass the strip through the inlet wedge-shaped tunnel plate (8) and the conical roller (20), and adjust the positions of the rear tension mechanism and the inlet and outlet limit adjustment mechanisms so that the strip is in the same straight line and at the same height. S2: According to the required inner diameter of the ring, correct the positions of the rear tension mechanism and the inlet and outlet limit adjustment mechanisms so that the strip is rolled into the conical roller (20) at a reasonable position along the generatrix from the cone apex angle. S3: According to the required thickness of the ring, adjust the roll gap thickness of the conical roller (20), set the rotational speed of the conical roller, and adjust the rotational speed of the material receiving mechanism motor to match the discharge speed and the rotational speed of the material receiving mechanism. S4: Start the rolling mill, and pass the formed ring strip through the outlet channel base (11) for stable rolling.
[0012] Compared with the prior art, the present invention has the following advantages and technical effects: 1. The upper and lower conical rollers are arranged symmetrically, parallel and coplanar along the generatrix of the conical roller to form a uniform and equal-thickness roll gap, improving the thickness uniformity of the formed strip. 2. The rear tension mechanism provides rear tension for the strip, and the inlet limit adjustment mechanism provides a limiting function for the strip to prevent the "tail swinging" and "undulating" phenomena that occur during the rolling process of the strip. 3. The outlet limit adjustment mechanism not only plays a limiting role, but also solves the "dragging" phenomenon of the strip in the roll gap caused by the gravity of the formed ring, improving the stability of the strip in the roll gap. 4. The material receiving mechanism can match the ring forming speed of the conical roller, reduce the influence of the formed ring on the subsequent rolling, and improve the quality and sustainability of the ring forming by the conical roller.
