Abstract
Description
Technical Field
[0001] This utility model relates to the field of cutting technology, specifically a centering roller cutting device. Background Technology
[0002] Centering rollers are key devices used in industrial production to center, position, or adjust the centerline of materials (such as metal sheets, strips, pipes, bars, etc.). They are mainly used in industries such as metallurgy, machining, and papermaking. During the production process, centering rollers need to be cut into the required size using a cutting device to facilitate subsequent processing.
[0003] When using a cutting device to cut a centering roller, the existing cutting devices clamp the material on one side but mostly do not have a material support function on the other side. As a result, after the material is cut into two pieces, the material on the other side rolls off due to the lack of support and limiting function, which can damage the outer side of the material or injure the operator. Therefore, a centering roller cutting device is proposed to solve the above-mentioned problems. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, this utility model provides a centering roller cutting device with advantages such as support and limiting. It solves the problem that when using a cutting device to cut a centering roller, the material on one side of the existing cutting device is clamped while the other side mostly lacks material support function. As a result, after the material is cut into two pieces, the material on the other side rolls off due to the lack of support and limiting function, which can damage the outer side of the material or injure the operator.
[0006] (II) Technical Solution
[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A centering roller cutting device is applied to a table body. An electric hydraulic push rod is fixedly connected inside the table body. A base is fixedly connected to the top of the electric hydraulic push rod. A rotating block is rotatably connected inside the base. A threaded rod is fixedly connected to the top of the rotating block. A handle is fixedly connected to the top of the threaded rod. A limiting rod is fixedly connected to the top of the base. A limiting block is fixedly connected to the top of the limiting rod. An upper pressure block is slidably connected to the outside of the limiting rod. Clamping blocks are fixedly connected to the opposite side of the base and the upper pressure block.
[0008] The beneficial effects of this utility model are: the height of the base can be adjusted by the electric hydraulic push rod, so that the two clamping blocks at the top of the base can contact the material. Then, the upper pressure block can drive the clamping block at the top to move down by the threaded rod and the sliding rod, so as to support and limit the other end of the material.
[0009] This centering roller cutting device has the advantage of supporting and limiting movement.
[0010] Based on the above technical solution, the present invention can be further improved as follows.
[0011] Furthermore, the outer side of the threaded rod is threaded with an upper pressure block, and the number of the bottom clamping blocks is two, arranged symmetrically from left to right.
[0012] The advantage of adopting the above-mentioned further solution is that the upper pressure block can be moved downwards via the threaded rod.
[0013] Furthermore, all three clamping blocks are arranged in an arc shape, with the top clamping block located at the geometric center of the bottom two clamping blocks.
[0014] The advantage of adopting the above-mentioned further solution is that, through the arc-shaped setting, the three clamping blocks can better fit with the material.
[0015] Furthermore, a clamping mechanism is fixedly connected to the top of the table, a cutting mechanism is provided inside the table, and a rotating mechanism is fixedly connected to the bottom of the cutting mechanism.
[0016] The advantage of adopting the above-mentioned further solution is that the centering roller can perform cutting through the cutting mechanism.
[0017] Furthermore, the bottom of the table is fixedly connected to four lifting table legs, which are arranged in a rectangular array.
[0018] The advantage of adopting the above-mentioned further solution is that the table height can be adjusted by raising and lowering the table legs.
[0019] Furthermore, a force-bearing block is fixedly connected to the opposite side of each of the two front lifting table legs and the two back lifting table legs. The same horizontal block is fixedly connected to the opposite side of each of the two force-bearing blocks, and an electric hydraulic push rod is fixedly connected inside the horizontal block.
[0020] The beneficial effect of adopting the above-mentioned further solution is that the four lifting table legs are made more stable through the force-bearing blocks and horizontal blocks. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] In the embodiments, by Figure 1-4 A centering roller cutting device is provided. This utility model is applied to a table body 1. An electric hydraulic push rod 2 is fixedly connected inside the table body 1. A base 3 is fixedly connected to the top of the electric hydraulic push rod 2. A rotating block 4 is rotatably connected inside the base 3. A threaded rod 5 is fixedly connected to the top of the rotating block 4. A handle 6 is fixedly connected to the top of the threaded rod 5. A limiting rod 7 is fixedly connected to the top of the limiting rod 7. A limiting block 8 is fixedly connected to the top of the limiting rod 7. An upper pressure block 9 is slidably connected to the outside of the limiting rod 7. Clamping blocks 10 are fixedly connected to the opposite side of the base 3 and the upper pressure block 9.
[0028] The outer thread of the threaded rod 5 is connected to an upper pressure block 9, and there are two bottom clamping blocks 10 arranged symmetrically on the left and right.
[0029] The upper pressure block 9 can be moved downwards via the threaded rod 5;
[0030] All three clamping blocks 10 are arranged in an arc shape, with the top clamping block 10 located at the geometric center of the bottom two clamping blocks 10;
[0031] The arc-shaped design allows the three clamping blocks 10 to better fit the material.
[0032] A clamping mechanism 11 is fixedly connected to the top of the table body 1, and a cutting mechanism 12 is provided inside the table body 1. A rotating mechanism 13 is fixedly connected to the bottom of the cutting mechanism 12.
[0033] The centering roller can be cut by the cutting mechanism 12;
[0034] The bottom of the table body 1 is fixedly connected to four lifting table legs 14, which are arranged in a rectangular array.
[0035] The table body 1 can be height-adjusted by raising and lowering the table legs 14;
[0036] The two front lifting table legs 14 and the two back lifting table legs 14 are fixedly connected to the opposite side of the force-bearing block 15. The two force-bearing blocks 15 are fixedly connected to the opposite side of the same horizontal block 16. An electric hydraulic push rod 2 is fixedly connected inside the horizontal block 16.
[0037] The force-bearing block 15 and the horizontal block 16 make the four lifting table legs 14 more secure.
[0038] Working principle:
[0039] The centering roller material is placed on top of the two bottom clamping blocks 10 via the clamping mechanism 11 and the cutting mechanism 12. When the height of the two bottom clamping blocks 10 is insufficient, the electric hydraulic push rod 2 is activated, causing the electric hydraulic push rod 2 to move the base 3 upward, which in turn causes the base 3 to move the two bottom clamping blocks 10 to the required position. Then, the clamping mechanism 11 is activated to clamp the material. Subsequently, the handle 6 is rotated, causing the handle 6 to drive the threaded rod 5 to rotate through the rotating block 4, which in turn causes the rotating block 4 to drive the upper pressure block 9 to move downward through the limiting rod 7, which in turn causes the upper pressure block 9 to drive the top clamping block 10 to move downward, so that the top clamping block 10 and the two bottom clamping blocks 10 clamp one end of the centering roller material, thereby preventing the other end from rolling off due to the lack of a limiting device when the material is cut into two ends.
