Description

Technical Field

[0001] The utility model relates to the field of plate rolling machine equipment, in particular to a hydraulic swing plate rolling machine for preventing plate rebound. Background Art

[0002] The hydraulic swing plate rolling machine is a shaping machine tool that uses the hydraulic principle to roll plates. It drives the swing arm and upper roller to lift and swing through the hydraulic system to achieve continuous bending of the plate. During the rolling process, the rebound of the plate is caused by the release of its internal stress, which will affect the rolling accuracy and forming quality. Therefore, when the hydraulic swing plate rolling machine rolls the plate, a series of measures must be taken to prevent the plate from rebounding and ensure that the workpiece that meets the requirements is rolled.

[0003] Through research and analysis, we found that the structures of most current plate rolling machines are relatively basic, and are unable to properly press the sides of the plates according to the thickness, thinness and specifications of the plates. As a result, during the rolling process, the plates are affected by gravity, which easily causes the plates to bend downward, resulting in the molded plates being out of round. In addition, during the rolling process, the plates will be affected by inertia, and the rebound phenomenon that occurs is not conducive to the quality of subsequent finished products. Therefore, it is necessary to improve the deficiencies and defects in the existing technology. Utility Model Content

[0025] like Figure 4 As shown, an X-axis slide groove 21 is provided on the X-axis adjustment mechanism 2, and the X-axis slide groove 21 is installed and fixed on the side plate of the discharge end of the hydraulic rolling machine body 1. An X-axis screw rod 22 is rotatably connected in the X-axis slide groove 21, and an X-axis slider 23 is threadedly connected to the X-axis screw rod 22, and the X-axis slider 23 is slidably connected in the X-axis slide groove 21.

[0026] like Figure 4 As shown, the Y-axis adjustment mechanism 3 is provided with a Y-axis slide groove 31, which is fixed to the upper side of the X-axis slider 23. A bidirectional screw rod 32 is rotatably connected in the Y-axis slide groove 31, and two Y-axis sliders 33 are threadedly connected to the bidirectional screw rod 32. The Y-axis sliders 33 are slidably connected in the Y-axis slide groove 31.

[0027] like Figure 4 As shown, a scale line 34 is installed on the side of the Y-axis slide groove 31 away from the discharge end of the hydraulic plate rolling machine body 1.

[0028] Embodiment 2:

[0029] The difference between this embodiment and embodiment 1 is that:

[0030] like Figure 4 As shown, the Z-axis adjustment mechanism 4 is provided with a Z-axis slide groove 41, which is fixed to the upper side of the Y-axis slider 33. A Z-axis screw rod 42 is rotatably connected in the Z-axis slide groove 41, and a Z-axis slider 43 is threadedly connected to the Z-axis screw rod 42. The Z-axis slider 43 maintains a sliding connection with the vertical groove on the Z-axis slide groove 41.

[0031] like Figure 5 As shown, the upper and lower synchronous adjustment mechanism 5 is provided with a variable slide groove 51, which is fixedly connected to the Z-direction slider 43. A two-way screw rod 52 is rotatably connected in the variable slide groove 51, and two adjustment blocks 53 are threadedly connected to the two-way screw rod 52. The two adjustment blocks 53 maintain a sliding connection with the variable slide groove 51 in the vertical direction, and the adjustment blocks 53 are rotatably connected in the direction away from the Z-direction slider 43 with a limiting roller 54.

[0032] The outer edges of the X-axis screw rod 22, the bidirectional screw rod 1 32, the Z-axis screw rod 42, and the bidirectional screw rod 2 52 are all fixedly connected with hand cranks, which facilitates the operator to rotate the X-axis screw rod 22, the bidirectional screw rod 1 32, the Z-axis screw rod 42, the bidirectional screw rod 2 52, etc. through the hand crank.

[0033] Working principle: Before using this utility model, Figure 1 As shown, the anti-rebound component 1 6 and the anti-rebound component 2 7 can be adjusted in position according to the width of the plate to be bent and the curvature required to be bent. Specifically, Figure 4 As shown, after the X-axis screw rods 22 on the two sets of X-axis adjustment mechanisms 2 are rotated in one direction at the same time, the X-axis screw rod 22 can drive the X-direction slider 23 to slide in the X-axis slide groove 21 through the thread to adjust the position of the Y-axis slide groove 31 on the X-axis slide groove 21. After the bidirectional screw rod 32 on the Y-axis adjustment mechanism 3 is rotated, the bidirectional screw rod 32 can drive the Y-direction sliders 33 at both ends to move toward or away from each other through the thread, thereby making the two sets of Z-axis adjustment mechanisms 4 on the upper side move toward or away from each other synchronously on the upper side of the Y-axis slide groove 31. When the Z-axis adjustment mechanism 4 moves, the operator can visually observe the horizontal spacing between the two sets of Z-axis adjustment mechanisms 4 through the scale line 34. The advantage of this adjustment is that when the spacing between the two sets of Z-axis adjustment mechanisms 4 is adjusted to adapt to the width of the plate, the plate can be prevented from being deviated during the plate rolling forming process, thereby ensuring the maintained forming quality. The above steps can complete the synchronous adjustment of the two sets of anti-rebound components 6 in the X-axis and Y-axis directions;

[0034] When adjusting the anti-rebound component 1 6, after rotating the Z-axis screw rod 42 on the Z-axis adjustment mechanism 4, the Z-axis screw rod 42 can drive the upper and lower synchronous adjustment mechanism 5 on one side of the Z-direction slider 43 to move up and down through the thread, and after rotating the bidirectional screw rod 2 52 on the upper and lower synchronous adjustment mechanism 5, the bidirectional screw rod 2 52 can drive the limiting rollers 54 on one side of the two adjustment blocks 53 to move toward or away from each other in the vertical direction through the thread, so as to adapt to the needs of rolling plates under different bending conditions and different thicknesses. By repeating the above steps, the relative positions of the two sets of anti-rebound components 2 7 can be synchronously adjusted;

[0035] During the plate rolling process, the plate is rolled into a circle by the cooperation of the upper and lower rollers on the hydraulic plate rolling machine body 1, and the bent plate part is transmitted outward from one side of the discharge port, and the end of the plate passes through the two limit rollers 54 on the anti-rebound component 1 6, and the upper and lower limit rollers 54 rotate on both sides of the bending part of the plate respectively, which can prevent the plate from twisting and deforming during rolling. When rolling thick-walled workpieces, if the plate is not supported in time, the plate will bend downward due to the action of gravity, resulting in the arc out of roundness of the formed plate; as the plate continues to be rolled, the end of the plate passes through the two limit rollers 54 on the anti-rebound component 2 7, and the upper and lower limit rollers 54 keep rotating with the upper and lower sides of the plate, and their main function is to prevent the plate from jumping or rebounding during rolling. When rolling thin-walled plates, if there are no upper and lower limits of the limit rollers 54, the plate may jump due to inertia, resulting in wavy deformation of the formed workpiece.
