Description

Technical Field

[0001] This utility model relates to the field of CNC ring rolling machine technology, and in particular to an adaptive adjustment mechanism for the roller gap of a CNC ring rolling machine. Background Technology

[0002] Ring rolling mills are essential equipment for expanding and shaping annular forgings, and are widely used in machinery manufacturing, aerospace, and other fields. During the ring rolling process, precise control of the roller gap plays a crucial role in the dimensional accuracy, surface quality, and production efficiency of the annular forgings.

[0003] Currently, the existing roller gap adjustment methods for ring rolling mills mainly have the following problems: most of them adopt manual adjustment or simple mechanical adjustment structures. The adjustment process depends on the operator's experience, making it difficult to achieve fast and accurate adjustment. This not only results in low efficiency, but also the adjustment accuracy cannot meet the production requirements of high-precision ring forgings, leading to large product size deviations and high scrap rates. Therefore, a CNC ring rolling mill roller gap adaptive adjustment mechanism is proposed. Utility Model Content

[0004] The purpose of this invention is to provide an adaptive adjustment mechanism for the roller gap of a CNC ring rolling mill, which solves the problems mentioned in the background art, where most of the adjustment is done manually or by simple mechanical means. The adjustment process relies on the operator's experience, making it difficult to achieve fast and accurate adjustment. This not only results in low efficiency but also fails to meet the production requirements of high-precision ring forgings, leading to large product size deviations and high scrap rates.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A CNC ring rolling mill roller gap adaptive adjustment mechanism includes a frame, two extension blocks fixedly connected to the top of the frame, an adjustment mechanism fixedly connected to the surface of the extension blocks, a fixed roller mounted on one lower surface of the frame, limit mechanisms mounted on both sides of the fixed roller, and an anti-detachment mechanism inserted into one side of the fixed roller. The adjustment mechanism includes a hydraulic rod fixedly connected to the surface of the extension blocks, a connecting frame fixedly connected to the end of the hydraulic rod, a movable roller rotatably connected inside the connecting frame, a PLC controller electrically connected to one side of the hydraulic rod via a power line, and a laser rangefinder electrically connected to one side of the PLC controller via a power line. The limit mechanism includes positioning rollers mounted on both sides of the fixed roller, fixed frames rotatably connected to both sides of the positioning rollers, and a cylinder A fixedly connected to one side of the fixed frame. The anti-detachment mechanism includes a positioning plate inserted into one side of the fixed roller, an auxiliary rotating roller mounted on the lower surface of the positioning plate, and a cylinder B fixedly connected to one side of the positioning plate.

[0006] As a further embodiment of this utility model, a rotating motor is fixedly connected to one side of the movable roller, and a heat dissipation box is installed on the surface of the rotating motor. The heat dissipation box serves to protect the rotating motor.

[0007] As a further embodiment of this utility model, the laser rangefinder is installed on the upper surface of the fixed roller, and the detection end of the laser rangefinder is located directly below the movable roller. The laser rangefinder serves to measure the gap.

[0008] As a further embodiment of this utility model, the lower surface of the positioning plate is provided with two limiting holes, and a limiting rod is slidably connected inside the limiting holes. The limiting rod serves to limit the positioning plate.

[0009] As a further embodiment of this utility model, upright plates are fixedly connected to both sides of the limiting rod, and a base is fixedly connected to the bottom of the upright plate. The base serves as the upright plate.

[0010] As a further embodiment of this utility model, a base plate is fixedly connected to one side of the base, and the base plate is fixedly connected to the bottom of the cylinder A. The cylinder A is used to drive the positioning roller to move.

[0011] As a further embodiment of this utility model, a sliding groove is provided in the middle of the upright frame, and the movable roller is slidably connected inside the sliding groove. The sliding groove serves to support the movable roller.

[0012] This utility model provides an adaptive adjustment mechanism for the roller gap of a CNC ring rolling mill, which has the following advantages: 1. The adaptive adjustment mechanism for the roller gap of this CNC ring rolling machine is designed so that, during operation, a laser rangefinder is installed on the upper surface of the fixed roller. The laser rangefinder emits a laser beam, which contacts the movable roller at the top. The laser beam reflects back to the rangefinder immediately after touching the movable roller. Through an ultra-high-speed time calculation chip, the time difference of the laser's round trip is accurately converted into real-time gap distance data between the fixed and movable rollers, and transmitted to the PLC controller at millisecond speeds. The PLC controller then controls the hydraulic rod to start, driving the movable roller at the bottom of the hydraulic rod to adjust its height. This achieves the effect of automatically adjusting the gap between the movable and fixed rollers, eliminating the need for manual operation and improving production efficiency.

[0013] 2. The adaptive adjustment mechanism for the roller gap of this CNC ring rolling machine, through the setting of a limiting mechanism and an anti-detachment mechanism, allows the circular workpiece to be placed on the fixed roller during use. Then, cylinders A and B are activated. Cylinder A drives the two top positioning rollers to press tightly against the surface of the circular workpiece, while cylinder B drives the positioning plate at the end to insert into the end of the fixed roller. The auxiliary rotating roller installed on the lower surface of the positioning plate also presses against the surface of the circular workpiece, thereby achieving the effect of limiting the circular workpiece and preventing it from falling off. This avoids equipment collision damage caused by workpiece displacement or falling off during the ring rolling process, reducing equipment downtime and maintenance costs. Attached Figure Description

The heat dissipation box 8 protects the rotating motor 7. The laser rangefinder 305 is installed on the upper surface of the fixed roller 4, and the detection end of the laser rangefinder 305 is located directly below the movable roller 303. The laser rangefinder 305 is used to measure the gap.

[0018] In this invention, the working steps of the device are as follows: First step: During use, a laser rangefinder 305 is installed on the upper surface of the fixed roller 4. The laser rangefinder 305 emits a laser beam, which contacts the movable roller 303 at the top. After the laser beam touches the movable roller 303, it is immediately reflected back to the rangefinder. Through an ultra-high-speed time calculation chip, the time difference of the laser's round trip is accurately converted into real-time gap distance data between the fixed roller 4 and the movable roller 303, and transmitted to the PLC controller 304 at millisecond speed. The PLC controller 304 then controls the hydraulic rod 301 to start, which drives the movable roller 303 at the bottom of the hydraulic rod 301 to adjust its height. Second step: When using it, place the ring workpiece on the fixed roller 4, and then start cylinders A503 and B603. Cylinder A503 drives the two top positioning rollers 501 to stick tightly to the surface of the ring workpiece, and cylinder B603 drives the end positioning plate 601 to insert into the end of the fixed roller 4. The auxiliary rotating roller 602 installed on the lower surface of the positioning plate 601 also sticks to the surface of the ring workpiece.
