Description

Technical Field

[0001] The utility model belongs to the technical field of plate clamping equipment, and specifically relates to a hydraulic double-roller clamping mechanism. Background Technique

[0002] A slitting line refers to a process for shearing plates in the metal processing industry. During the slitting line process, slitting line equipment is usually used to perform the shearing operation on the plates to obtain sheet materials with required dimensions and shapes. During the sheet material cutting process, it is necessary to clamp and position the sheet material.

[0003] In the existing technology, the sheet material is usually fixed at the shearing position by rotating bolts. However, since the thickness, hardness, and processing requirements of the sheet material are different, it may not be possible to use a hydraulic drive method to fix the sheet material when clamping the sheet material, resulting in difficulty in precisely controlling the magnitude of the clamping force. In this case, it is impossible to adjust the clamping force according to the characteristics of the sheet material, and it is also impossible to ensure that the sheet material receives an appropriate clamping force during the shearing process, which may cause the sheet material to slide or deform. In addition, the bolts for fixing the sheet material usually have difficulty in providing a uniform clamping force distribution, which will cause the sheet material to be unevenly stressed and may lead to tilting or deformation.

[0004] Regarding the problems in the related technology, no effective solution has been proposed yet. Content of the Utility Model

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0026] Refer to Figures 1-3 , a hydraulic double-roller clamping mechanism, including a support platform 1, a side plate 2 is fixedly connected to the top of the support platform 1, there are two side plates 2, and the two side plates 2 are symmetrically distributed with the central axis of the support platform 1 as the center. A clamping mechanism 3 for clamping and positioning the sheet material during the cutting process is provided on the side plate 2, and an adjusting mechanism 4 for horizontally penetrating the sheet material to the center above the support platform 1 is provided on the clamping mechanism 3;

[0027] The clamping mechanism 3 includes a hydraulic rod 31 fixedly connected to the top of the side plate 2. The hydraulic rod 31 is located at the center of the top of the side plate 2. The telescopic end of the hydraulic rod 31 is fixedly connected with a sleeve 32. The number of the side plates 2, the hydraulic rods 31 and the sleeves 32 is equal. One end of the sleeve 32 is rotatably connected with an upper pressure roller 33. The two sleeves 32 are located at both ends of the upper pressure roller 33. The outer side of the bottom of the side plate 2 is fixedly connected with a bottom block 34. A lower pressure roller 35 is rotatably connected to the bottom block 34. There are two bottom blocks 34, and the two bottom blocks 34 are symmetrically distributed with the central axis of the lower pressure roller 35 as the center, and the lower pressure roller 35 is located directly below the upper pressure roller 33. The end of the sleeve 32 away from the upper pressure roller 33 is fixedly connected with a lifting block 36. The lifting block 36 is located directly above the bottom block 34. The bottom of the lifting block 36 is fixedly connected with a positioning rod 37. Two positioning rods 37 are movably penetrated through each bottom block 34. The positioning rod 37 movably penetrates through the inside of the bottom block 34. The outer side wall of the positioning rod 37 is slidably connected with a slider 39. The top of the slider 39 is fixedly connected with a spring 310. The spring 310 is located between the slider 39 and the lifting block 36. The top of the spring 310 is fixedly connected with the bottom of the lifting block 36. After the hydraulic rod 31 operates, the sleeve 32 drives the upper pressure roller 33 to move and adjust, and the height of the upper pressure roller 33 is adjusted. The lifting block 36 and the positioning rod 37 increase the accuracy of the up and down movement of the upper pressure roller 33. After the slider 39 moves to fit with the bottom block 34, the lifting block 36 continues to move downward, and the spring 310 is compressed and deformed, further increasing the clamping ability of the upper pressure roller 33 and the lower pressure roller 35 on the sheet material, and at the same time, the clamping force on the sheet material can be adjusted, avoiding the consequence of the sheet material being deformed or damaged due to excessive clamping force, thereby increasing the stability of the sheet material during the shearing process.

[0028] Refer to Figures 2-3 , a positioning hole 38 is opened on the bottom block 34. The inner circumference of the positioning hole 38 is equal to the outer circumference of the positioning rod 37, and the inner circumference of the positioning hole 38 is smaller than the outer circumference of the slider 39. The positioning hole 38 facilitates the positioning rod 37 to penetrate through the inside of the bottom block 34, and the positioning rod 37 is slidably connected with the bottom block 34 through the positioning hole 38.

[0029] Refer to Figures 2-3 , the lifting block 36 is located directly above the bottom block 34, the positioning rod 37, the positioning hole 38 and the slider 39 are coaxial. During the movement of the lifting block 36, the positioning rod 37 is driven to move downward, avoiding the deviation of the lifting block 36 during the movement, so that the upper pressure roller 33 is always directly above the lower pressure roller 35.

[0030] Refer to Figures 1-4, the adjusting mechanism 4 includes a frame plate 41 fixedly connected to the outer side wall of the lifting block 36. A threaded rod 42 is threadedly connected inside the frame plate 41. Two threads with opposite directions are provided on the outer side wall of the threaded rod 42. A sleeve block 43 is threadedly connected to the outer side wall of the threaded rod 42. There are two sleeve blocks 43, and the two sleeve blocks 43 are symmetrically distributed with the central axis of the frame plate 41 as the center. A moving block 44 is fixedly connected to the bottom of the sleeve block 43. The moving block 44 is located directly below the sleeve block 43. After the threaded rod 42 rotates, the sleeve block 43 drives the moving block 44 to move towards the direction close to the sheet material.

[0031] Refer to Figure 4 , a U-shaped frame 45 is fixedly connected to the bottom of the moving block 44. The longitudinal section of the U-shaped frame 45 is U-shaped. A roller 46 is rotatably connected inside the U-shaped frame 45. The moving block 44 drives the U-shaped frame 45 to move, so that the roller 46 moves and adjusts to fit both sides of the sheet material, and pushes the sheet material to move, so that the sheet material moves horizontally on the central axis above the support table 1.

[0032] Refer to Figure 4 , a hexagonal hole 47 is provided at one end of the threaded rod 42. A hexagonal rod 48 is inserted through the hexagonal hole 47 of the threaded rod 42. The hexagonal hole 47 is adapted to the hexagonal rod 48. A rotating block 49 is fixedly connected to one end of the hexagonal rod 48. After the hexagonal rod 48 is inserted into one end of the threaded rod 42 through the hexagonal hole 47, the rotating block 49 drives the hexagonal rod 48 to rotate, so that the threaded rod 42 rotates accordingly.

[0033] Refer to Figure 1 , a vertical steel 5 is fixedly connected to the bottom of the support table 1. There are four vertical steels 5, and the four vertical steels 5 are located at the four corners of the bottom of the support table 1. A bottom plate 6 is fixedly connected to the bottom of the vertical steel 5. The vertical steel 5 and the bottom plate 6 stably support the support table 1. Both the vertical steel 5 and the bottom plate 6 are made of steel.

[0034] Working principle: First, move the support table 1 to a suitable position on the longitudinal shearing line, so that the support table 1 is located on one side of the shearing area of the longitudinal shearing line for transporting the sheet material. The sheet material passes through the gap between the lower pressing roller 35 and the upper pressing roller 33. The bottom of the sheet material is attached to the outer side wall of the lower pressing roller 35. The hydraulic rod 31 operates, and the sleeve 32 drives the upper pressing roller 33 to move downward, so that the sheet material is respectively attached to the upper pressing roller 33 and the lower pressing roller 35. The positioning rod 37 and the positioning hole 38 increase the accuracy of the downward movement of the lifting block 36. At the same time, after the slider 39 moves and fits with the bottom block 34, the spring 310 is compressed and deformed, so that the clamping force on the sheet material can be adjusted, avoiding deformation or damage of the sheet material caused by excessive clamping force, and then facilitating the positioning of the sheet material during the cutting process on the longitudinal shearing line and increasing the stability of the sheet material cutting;

[0035] When the sheet material passes through the upper pressure roller 33 and the lower pressure roller 35, the hexagonal rod 48 is inserted into one end of the threaded rod 42 through the hexagonal hole 47. During the process of the height change of the lifting block 36, the adjusting mechanism 4 also changes accordingly. Rotate the rotating block 49, the threaded rod 42 rotates accordingly, the sleeve block 43 moves towards the direction close to the sheet material, the moving block 44 moves accordingly, and the U-shaped frame 45 drives the roller 46 to move to fit the side surface of the sheet material, thereby correcting the position of the sheet material, so that the sheet material moves and is transmitted at the center above the support table 1.

[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
