Technical Field

[0001] This utility model relates to the field of press technology for straightening rollers, and in particular to a press for straightening diamond rollers. Background Technology

[0002] A roller straightening press is a device for correcting deformed diamond rollers. Announcement No.: CN221209459U discloses a roller straightening machine for production, including a base and a fixing frame. The fixing frame is fixedly located at the top center of the base. It also includes a positioning component and a straightening component. This utility model belongs to the field of roller production technology, specifically a roller straightening machine that can clamp and fix both ends of rollers of different lengths, solving the problem of roller rotation during calibration. It ensures straightening force through a hydraulic rod, improving the straightening effect. However, in practical applications, it has some shortcomings. The device relies on only one set of straightening components, resulting in low stability during use and a tendency for over-correction or incomplete correction. Improvements are needed. Utility Model Content

[0003] The purpose of this utility model is to solve the technical problems mentioned in the background art.

[0004] The present invention adopts the following technical solution: a press for straightening diamond rollers, comprising a mounting plate, a bracket fixedly mounted on the bottom surface of the mounting plate, a first rotating roller fixedly mounted on the surface of the mounting plate, a groove formed on the surface of the mounting plate, a slider slidably connected inside the groove, a second rotating roller fixedly mounted on the upper surface of the slider, a moving plate slidably connected to the bottom surface of the moving block, a first lead screw threadedly connected inside the moving plate, and a motor fixedly mounted at one end of the first lead screw.

[0005] Preferably, the number of the sliding grooves is five sets, and the five sets of sliding grooves are equidistantly distributed. Here, the ability to cover and adjust the entire length of the long roller is enhanced, the multi-point equidistant layout makes the pressure distribution uniform, avoids single-point overload, improves the stability of the slider movement trajectory, and prevents skewing and jamming.

[0006] Preferably, there are four sets of first-type rotating rollers and five sets of second-type rotating rollers. The first-type and second-type rotating rollers are equidistantly distributed and arranged alternately. Here, the four sets of fixed first-type rotating rollers provide a reference support surface, and the five sets of adjustable second-type rotating rollers form dense pressure points. The alternating arrangement creates a continuous and progressive straightening path, eliminating straightness deviations. The equidistant distribution ensures uniform transmission of straightening force and avoids stress concentration.

[0007] Preferably, the middle part of the first and second rollers is an arc-shaped surface. Here, the arc-shaped contour naturally fits the outer circle of the roller shaft, increasing the contact area and avoiding damage to the workpiece surface from sharp edges. This is particularly suitable for precision diamond roller shafts, adapting to the curved surface contact of roller shafts of different diameters and improving versatility.

[0008] Preferably, a fixing block is fixedly mounted on the surface of the mounting plate, and the surface of the fixing block has an arc-shaped groove, with limit grooves on both sides of the fixing block. Here, the arc-shaped groove provides an auxiliary positioning reference to ensure initial alignment of the workpiece, and the limit grooves constrain the movement trajectory of the moving block, improving adjustment stability.

[0009] Preferably, a movable block is slidably connected inside the limiting groove, a second lead screw is fixedly installed on the upper surface of the movable block, the second lead screw is threadedly connected inside the fixed block, and a turntable is fixedly installed at the top end of the second lead screw.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] 1. In this utility model, by starting the motor, the motor drives the No. 1 lead screw to rotate, which in turn drives the moving plate to move. The moving plate drives the slider to slide in the slide groove, so that the five sets of No. 2 rotating rollers press and straighten the roller shaft, thereby achieving simultaneous and all-round pressing of the roller shaft and preventing uneven force during the processing of the roller shaft.

[0012] 2. In this utility model, by rotating the turntable, the No. 2 lead screw is driven to rotate, so that the moving block slides inside the fixed block. The limiting groove restricts the moving block to slide inside the fixed block. The roller shaft is fixed and clamped by the arc surface, so as to achieve stable fixation of the roller shaft and prevent the roller shaft from shaking and deforming during the straightening process.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1

[0022] Please see Figure 1-2 This utility model provides a technical solution: a press for straightening diamond roller shafts, including a mounting plate 1, a bracket 2 fixedly mounted on the bottom surface of the mounting plate 1, and four sets of first-order rollers 3 and five sets of second-order rollers 6 fixedly mounted on the surface of the mounting plate 1. The first-order rollers 3 and second-order rollers 6 are equidistantly distributed and staggered. The four sets of fixed first-order rollers 3 provide a reference support surface, and the five sets of adjustable second-order rollers 6 form dense pressure points. The staggered arrangement forms a continuous and progressive straightening path, eliminating straightness deviations. The equidistant distribution ensures uniform straightening force transmission and avoids stress concentration. The middle part of the first-order rollers 3 and second-order rollers 6 is an arc-shaped surface, and the arc-shaped contour is parallel to the outer circle of the roller shaft. The fit is close, increasing the contact area and avoiding damage to the workpiece surface from sharp edges. It is especially suitable for precision diamond rollers, adapting to the curved surface contact of rollers of different diameters, improving versatility. The surface of the mounting plate 1 is provided with five sets of sliding grooves 4, which are equidistantly distributed to enhance the ability to cover the entire length of long rollers. The multi-point equidistant layout makes the pressure distribution uniform, avoids single-point overload, improves the stability of the sliding trajectory of the slider 5, and prevents skewing and jamming. The slider 5 is slidably connected inside the sliding groove 4. The second rotating roller 6 is fixedly installed on the upper surface of the slider 5. The bottom surface of the moving block 13 is slidably connected to the moving plate 7. The moving plate 7 is threadedly connected to the first lead screw 8. One end of the first lead screw 8 is fixedly installed with a motor 9.

[0023] Example 2

[0024] Please see Figure 3-4A fixing block 10 is fixedly installed on the surface of the mounting plate 1. An arc-shaped groove 11 is opened on the surface of the fixing block 10. Limiting grooves 12 are opened on both sides of the fixing block 10. The arc-shaped groove 11 provides an auxiliary positioning reference to ensure the initial alignment of the workpiece. The limiting groove 12 constrains the movement trajectory of the moving block 13 and improves the adjustment stability. The moving block 13 is slidably connected inside the limiting groove 12. A second lead screw 14 is fixedly installed on the upper surface of the moving block 13. The second lead screw 14 is threadedly connected inside the fixing block 10. A turntable 15 is fixedly installed at the top of the second lead screw 14.

[0025] Working principle: During operation, the roller shaft to be straightened is first placed in the arc-shaped groove 11 of the fixing block 10 of the mounting plate 1. The limiting groove 12 is used for initial centering and positioning. The rotating turntable 15 clamps the roller shaft together with the moving block 13 and the fixing block 10. The four sets of fixed first rollers 3 serve as the reference support surface to provide stable support. Then, the motor 9 is started to drive the first lead screw 8 to rotate, which drives the moving plate 7 to move along the five sets of equally distributed slide grooves 4. The five sets of second rollers 6 move towards the roller shaft synchronously through the slider 5. Their arc-shaped contact surfaces adaptively wrap around the workpiece surface, completing the diameter adaptation and initial straightening. At the same time, the staggered first rollers 3 and second rollers 6 form a continuous wave-shaped pressure path. Combined with the central arc surface to increase the contact area to avoid stress concentration, and with the flexible pressure transmission of the five sets of slide grooves 4, the entire section of the roller shaft is gradually straightened.
