Description

Technical Field

[0001] The utility model relates to the technical field of cutting devices, in particular to a cutting device for a pressure vessel. Background Art

[0002] Pressure vessels are generally cylindrical, with a few being spherical or other shapes. Cylindrical pressure vessels are usually composed of parts and components such as cylinders, heads, connecting pipes, flanges, etc. The higher the working pressure of the pressure vessel, the thicker the wall of the cylinder should be.

[0003] Cutting is a process in the production of pressure vessels. Cutting is also called cutting. It refers to the process of separating the required blanks from the raw materials with the lines crossed. There are two methods of cutting in the production process of pressure vessels: mechanical cutting and thermal cutting. Mechanical cutting mainly includes shearing, sawing, milling and punching, while thermal cutting mainly includes flame cutting.

[0004] The prior art patent document with publication number CN219944764U provides a cutting device for a pressure vessel, which drives a cutting disc to rotate by setting a driving motor to achieve the effect of cutting the pressure vessel, and drives an adjusting screw to rotate by setting a servo motor, and drives a threaded sleeve and a telescopic cylinder to move by rotating the adjusting screw, so as to facilitate adjusting the position of the cutting disc to cut different sizes.

[0005] In the above-mentioned prior art, although the cutting device drives the threaded sleeve and the telescopic cylinder to move by adjusting the rotation of the lead screw, so as to adjust the position of the cutting disk for cutting different sizes, the cutting device in the patented technology limits and fixes the pressure vessel by two clamps, and the cutter moves downward to cut the pressure vessel. During the cutting process, the pressure vessel may need to be rotated to cut at different angles of the pressure vessel, and then the pressure vessel needs to be reinstalled, which is time-consuming and labor-intensive, and reduces the cutting efficiency. Therefore, we need a cutting device for pressure vessels. Utility Model Content

[0028] The mounting assembly 8 includes a connecting groove 801, a positioning groove 802 is provided on the top of the cutting mechanism 7, and a positioning rod 803 is snap-connected to the inner wall of the positioning groove 802, a baffle 804 is fixedly connected to one side of the positioning rod 803, and a spring 805 is installed on one side of the baffle 804, and a pull rod 806 is sleeved on the inner wall of the spring 805.

[0029] Through the above technical solution, the manual wheel 301 drives the screw rod 302 to rotate, so that the clamping plate 303 moves inward to limit and fix the pressure vessel. During the cutting process, the motor 304 can be started, and the motor 304 drives the first gear 305 to drive the second gear 306 to rotate, which can then drive the workbench 2 to rotate, so that the pressure vessel fixed on the workbench 2 is rotated, thereby achieving the effect of rotating the pressure vessel after it is fixed. There is no need for the staff to disassemble, install and adjust again, thereby improving the cutting efficiency of the pressure vessel.

[0030] Specifically, a water spray mechanism 4 is provided on one side of the base 1 .

[0031] Through the above technical solution, the water spray mechanism 4 can be arranged to conveniently flush the waste chips generated after cutting into the collection box, thereby completing the collection of the waste chips.

[0032] Specifically, the manual wheel 301 forms a movable structure through the screw rod 302 and the clamping plate 303, and the threads on both sides of the screw rod 302 have opposite rotation directions, and the number of the clamping plates 303 is two.

[0033] Through the above technical solution, it is convenient to rotate the manual wheel 301 by hand to drive the screw rod 302 to rotate and move the clamping plate 303 at the same time. Since the two clamping plates 303 are symmetrically arranged on both sides of the screw rod 302, the rotation of the screw rod 302 drives the two clamping plates 303 to move relative to each other, thereby achieving the effect of relative movement of the two clamping plates 303.

[0036] Specifically, the base 1 forms a sliding structure through the sliding groove 307 and the sliding rod 308 , and the shape and size of the sliding groove 307 match the shape and size of the sliding rod 308 .

[0037] The above technical solution facilitates the synchronous sliding of the workbench 2 in the slide groove 307 through the slide rod 308 during the rotation process, so as to prevent the workbench 2 from tilting during the rotation process, thereby improving the stability of the workbench 2 during rotation.

[0038] Specifically, the shape and size of the inner wall of the connecting groove 801 matches the shape and size of the top of the cutting mechanism 7 , and the shape and size of the positioning groove 802 matches the shape and size of the positioning rod 803 .

[0039] Through the above technical scheme, it is convenient to connect the top of the cutting mechanism 7 with the moving block 6 through the set connection groove 801, and the connection is extended by two positioning rods 803 into the two positioning grooves 802 at the top of the cutting mechanism 7 to limit and fix it to prevent the cutting mechanism 7 from falling, thereby achieving the limiting effect.

[0040] Specifically, the positioning rod 803 forms a fixed structure through the baffle plate 804 and the pull rod 806 , and the baffle plate 804 is arranged between the positioning rod 803 and the pull rod 806 .

[0041] Through the above technical solution, it is convenient to pull the pull rod 806 to move the positioning rod 803. The positioning rod 803 extends into the positioning groove 802 for connection through the elastic pressure of the spring 805. Pulling the pull rod 806 compresses the spring 805 on one side of the baffle 804, which makes it easier to disassemble and install the cutting mechanism 7, and facilitates the staff to repair it later.

[0042] Working principle: When using the pressure vessel cutting device, first, when installing and cutting the pressure vessel, place the pressure vessel between the two clamping plates 303, then turn the manual wheel 301 by hand, the manual wheel 301 drives the screw rod 302 to rotate, the screw rod 302 drives the two clamping plates 303 to move relative to each other due to the opposite rotation directions of the threads on both sides, and then the clamping plates 303 limit and fix the pressure vessel, and then start the motor 304, the motor 304 drives the first gear 305 to rotate, the first gear 305 drives the second gear 306 to rotate due to the meshing action, the second gear 306 is connected to the workbench 2 to rotate the workbench 2, and then the pressure vessel on the top of the workbench 2 rotates, at the same time, the workbench 2 is rotated through the slide rod 30 8 slides synchronously in the slide groove 307 to prevent the workbench 2 from tilting during the rotation process, thereby improving the stability of the workbench 2 during rotation. After the cutting is completed, when the cutting mechanism 7 needs to be inspected and repaired, it is only necessary to pull the pull rods 806 on both sides of the moving block 6 by hand, and the pull rods 806 drive the positioning rods 803 on one side of the baffle 804 to move outward, and the positioning rods 803 are disengaged from the positioning groove 802, thereby releasing the fixation of the cutting mechanism 7, and then the top of the cutting mechanism 7 is pulled out of the connecting groove 801, and the positioning rods 803 are extended into the positioning groove 802 by the elastic pressure of the spring 805 for connection. For the subsequent installation, it is only necessary to loosen the pull rods 806 and re-limit the cutting mechanism 7, which completes all the work.
