Description

Technical Field

[0001] The utility model relates to the technical field of steel structure production, in particular to a cutting device for steel structure production. Background Art

[0002] Steel structures are mainly made of steel materials such as steel sections and steel plates, including steel beams, steel columns, steel trusses and other components. These components are tightly connected together through various connection methods (such as welds, bolts or rivets) to form a stable overall structure. Steel structures are building structural elements made of steel. They are usually used to construct various types of buildings and structures, including industrial buildings, commercial buildings, residential buildings and public facilities. Steel structures have been widely used in modern buildings due to their high strength, good plasticity and toughness, fast construction, excellent seismic performance and reusability.

[0003] Steel structures are usually cut by flame cutting or plasma cutting. In the prior art, when performing circular cutting operations on steel structures, a circular cutting bracket is usually used to clamp the cutting gun for cutting. However, when the existing circular cutting bracket is used, its base is used as the center of the circle. After the cutting is completed, the position of the bracket needs to be changed for the next circular cutting operation. The position change operation is frequent, which affects the cutting efficiency. In addition, due to the limitation of the base volume, it cannot cut circles with smaller diameters. The scope of application is not wide enough, which affects the use effect. Therefore, there is an urgent need for a cutting device for steel structure production that is easy to operate and has a wide range of applications to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0027] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example:

[0029] like Figures 1 to 6 As shown, a cutting device for steel structure production includes a base 3, an electromagnet 9 is embedded at the bottom of the base 3, a vertical rod 1 is arranged on the upper side of the base 3, a cross bar 4 is fixedly arranged on the top of the vertical rod 1, a movable sliding sleeve 12 is sleeved on the cross bar 4, a connecting rod 5 is fixedly connected to the lower side of the ring surface of the movable sliding sleeve 12, a supporting frame 6 is movably connected to the lower end of the connecting rod 5, a threaded screw 21 is penetrated inside the supporting frame 6, a handle 20 is assembled at the right end of the threaded screw 21, a slide plate 22 is screwed on the threaded screw 21 through a thread, and a positioning rod 22 is rotatably connected to the lower side of the slide plate 22 through a pin shaft. Tube 7, the bottom of the positioning tube 7 is a conical structure with an opening, a notch 19 is opened on the right side of the ring surface of the positioning tube 7, a cutting gun 8 is placed inside the notch 19, and the head of the cutting gun 8 is located at the opening of the positioning tube 7. This design solves the problem that when the existing circle cutting bracket is in use, its base 3 is used as the center of the circle. After the cutting is completed, the position of the bracket needs to be changed for the next circle cutting operation. The position change operation is frequent, which affects the cutting efficiency. In addition, due to the volume limitation of the base 3, it cannot cut smaller diameter circles, and the scope of application is not wide enough, which affects the use effect.

[0030] The shaft seat 2 is fixed on the upper side of the base 3, and the vertical rod 1 is rotatably connected to the shaft seat 2 through a bearing. This design allows the vertical rod 1 to rotate freely relative to the shaft seat 2, which is convenient for rotating and adjusting the direction and position of the cutting gun 8, and can adjust the cutting gun 8 to other positions to be cut on the steel structure to meet different cutting needs, without the need for complicated disassembly and assembly processes, thereby saving time and labor, and greatly improving the flexibility and ease of use of the device.

[0031] A horizontal ear plate 10 is provided on the annular surface of the vertical pole 1, and an adjusting bolt a11 is threaded through the ear plate 10. This design forms a locking structure through the ear plate 10 and the adjusting bolt a11, providing a locking function for the vertical pole 1, enabling the device to rotate to an appropriate position for locking, reducing vibration and deviation during the cutting process, and ensuring cutting stability.

[0032] A limit slot 13 is provided on the upper side of the ring surface of the crossbar 4, and a limit block 15 is fixed on the upper side of the inner wall of the movable sleeve 12. The limit block 15 fits into the limit slot 13 and can slide therein. The movable sleeve 12 can drive the connecting rod 5 and the cutting gun 8 thereon to move horizontally, and the setting of the limit slot 13 and the limit block 15 plays a role of limit guide for the movement of the movable sleeve 12, preventing it from rotating and deviating.

[0033] An adjusting bolt b14 is provided through the upper side of the movable sleeve 12, and the adjusting bolt b14 is screwed to the movable sleeve, and the lower end thereof extends into the limiting slide groove 13. The design provides locking kinetic energy for the movable sleeve 12 through the adjusting bolt b14, and can fix the movable sleeve 12 in the current position, preventing the movable sleeve 12 from driving the cutting gun 8 to move during the cutting process. When the adjusting bolt b14 is tightened, it can increase the friction between the movable sleeve 12 and the crossbar 4, thereby fixing the movable sleeve 12 in a specific position and improving the stability of the entire device.

[0034] The left end of the support frame 6 is connected to the connecting rod 5 through a rotating joint 17, and a micro bearing is installed at the connection between the rotating joint 17 and the connecting rod 5. The design enables the support frame 6 to be rotatably connected to the vertical rod 1 through the rotating joint 17 and the micro bearing, and then the cutting gun 8 can be driven to rotate during cutting, which is convenient for cutting the steel structure into a circle.

[0035] A laser pen 16 is fixedly provided at the lower end of the upright pole 1, and the laser emitted by the laser pen 16 is located on the axis of the upright pole 1. The laser pen 16 can emit laser light to the steel structure, and the laser provides a reference for the center of the cut circle, which is convenient for the operator to determine the center of the cut circle. The operator can observe and adjust the cutting position more intuitively, thereby simplifying the operation process and improving work efficiency.

[0036] The support frame 6 is provided with a scale 18 on both the front and rear sides, and the slide plate 22 is provided with a vertical pointer 23 on both the front and rear sides, and the pointer 23 is located outside the scale 18. The pointer 23 on the slide plate 22 can move with the movement of the slide plate 22, and the current position of the slide plate 22 can be accurately read by corresponding to the scale 18, so that the operator can intuitively understand the precise position of the cutting gun 8, conveniently control the radius length of the cutting circle, and thus perform precise cutting operations. By directly observing the position of the pointer 23 on the scale 18, the operator can quickly and accurately adjust the slide plate 22 to the desired position without the need for additional measuring tools, thereby improving work efficiency.

[0037] The working principle of the cutting device for steel structure production is as follows: first, the operator places the device on the steel structure to be cut, starts the electromagnet 9, and the electromagnet 9 generates magnetic force after being energized to firmly adsorb the device on the surface of the steel structure. Next, the laser pen 16 at the lower end of the vertical rod 1 is used to emit laser to determine the center position of the cutting circle. Then, according to the needs, the horizontal movement of the movable sleeve 12 on the cross bar 4 and the movement of the slide plate 22 inside the support frame 6 are used to drive the positioning cylinder 7 to move horizontally to accurately adjust the radial position of the cutting gun 8, thereby determining the radius of the cutting circle. After determining the cutting position and radius, the operator uses the adjusting bolt a11 to lock the position of the vertical rod 1 to prevent it from rotating during the cutting process. At the same time, the adjusting bolt b14 is used to lock the position of the movable sleeve 12 on the cross bar 4 to ensure the stability of the cutting gun 8 during the cutting process. The cutting gun 8 is placed in the positioning cylinder 7 through the notch 19, and it is ensured that the gun head of the cutting gun 8 is located at the opening of the positioning cylinder 7, ready for cutting. Start the cutting gun 8 and push the cutting gun 8 to rotate along the rotating joint 17 so that it can cut along a predetermined circular trajectory to achieve circular cutting of the steel structure. When the cutting is completed, close the cutting gun 8, unlock the locking bolt on the vertical pole 1, rotate the cutting gun 8 to the next position to be cut, and repeat the above steps to perform the next cutting operation.

[0038] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
