Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe cutting, in particular to a steel pipe cutting device. Background Technique

[0002] A steel pipe is a metal material made of steel with a hollow cross-section and a length much greater than the outer diameter. In the fields of construction, bridges, etc., a cutting device is needed to cut the steel pipe into different lengths to meet the requirements of different building and bridge structures.

[0003] A Chinese patent with the publication number CN113909555A discloses a steel pipe positioning and cutting device, belonging to the field of steel pipe cutting; a steel pipe positioning and cutting device includes a support mechanism, a pressing mechanism, a rotating mechanism, a cutting mechanism and a limiting mechanism; two pressing mechanisms are installed on the upper end of the bottom plate, and the pressing mechanism includes a first fixed seat that can be lifted, and a rotating wheel is rotatably connected to the first fixed seat. The two rotating wheels are respectively located directly above the first support plate and the second support plate. A rotating mechanism is installed on the upper end of the bottom plate, and the rotating mechanism is used to drive the steel pipe to rotate; when the device is in use, a limiting mechanism is installed at the upper end of the cutting mechanism to control the cutting timing of the cutting mechanism, and to avoid the cutting mechanism from performing a cutting action when the steel pipe is not clamped, ensuring the subsequent cutting effect.

[0004] For existing steel pipe cutting devices, when cutting a steel pipe, it is first necessary to mark the steel pipe by drawing a line, and then use a cutting tool to cut it to complete the fixed-length cutting of the steel pipe. Each time a line is drawn, the steel pipe needs to be measured. However, most of the time, the lengths, specifications, etc. of the same batch of steel pipes are exactly the same. Repeated measurement and line drawing waste a lot of time and increase the labor intensity, resulting in a decrease in production efficiency; therefore, a steel pipe cutting device is proposed for the above problems.

When cutting a steel pipe, first, the position of the baffle 12 needs to be adjusted according to requirements. By moving the sliding seat 11, the baffle 12 also moves accordingly. Align with the scale ruler 14. When the distance between the baffle 12 and the cutting knife 5 meets the cutting length requirement, the sliding seat 11 is fixed by the action of the locking bolt 13. Thus, the position of the baffle 12 can be adjusted according to the cutting length requirement, which is convenient for subsequent fixed-length cutting operations of the steel pipe. When one end of the steel pipe moves to contact the baffle 12, rotate the rotating cap 7 to make the screw rod 3 drive the cutting knife 5 to move vertically down until it contacts the surface of the steel pipe. Through the action of the first motor 6, the cutting knife 5 rotates, so that the steel pipe can be cut. Without repeated measurement and marking, the fixed-length cutting operation of the steel pipe can be completed, greatly improving the work efficiency.

[0025] Please refer to Figures 6 - 7 As shown in the figure, two inclined fixing rods 15 are fixedly connected to the base 1, a fixing sleeve 16 is fixedly connected in cooperation with the two inclined fixing rods 15, a rotating sleeve 17 is rotatably installed in the fixing sleeve 16, a ring gear 18 is fixedly connected to the rotating sleeve 17, a support seat is fixedly connected to the base 1, a second motor 19 is installed on the support seat, the output end of the second motor 19 is installed with a gear 20, and the gear 20 meshes with the ring gear 18.

[0026] Please refer to Figures 4 - 5As shown in the figure, two arc-shaped slide rails 21 are fixedly connected to the base 1. A movable seat 22 is sleeved in cooperation with the two arc-shaped slide rails 21. Two fixing plates 23 are fixedly connected to the base 1.

[0027] Working principle: For the existing steel pipe cutting device, when cutting a steel pipe, it is first necessary to mark the steel pipe by scribing, and then use a cutting tool to cut it to complete the fixed-length cutting of the steel pipe. Each time of scribing requires measuring the steel pipe. However, most of the time, the lengths, specifications, etc. of the steel pipes in the same batch are exactly the same. Repeated measurement and scribing waste a lot of time and increase the labor intensity, resulting in a reduction in production efficiency. Therefore, a steel pipe cutting device is proposed for the above problems. When cutting a steel pipe, first, the position of the baffle 12 needs to be adjusted according to requirements. By moving the sliding seat 11, the baffle 12 also moves accordingly. Align with the scale ruler 14. When the distance between the baffle 12 and the cutting tool 5 meets the cutting length requirement, through the action of the locking bolt 13, the sliding seat 11 is fixed, so that the position of the baffle 12 can be adjusted according to the cutting length requirement, which is convenient for subsequent fixed-length cutting operation of the steel pipe. When one end of the steel pipe moves to contact the baffle 12, rotate the rotating cap 7 to make the screw rod 3 drive the cutting tool 5 to move vertically down until it contacts the surface of the steel pipe. Through the action of the first motor 6, the cutting tool 5 rotates, so that the steel pipe can be cut. Without repeated measurement and scribing, the fixed-length cutting operation of the steel pipe can be completed, greatly improving the work efficiency.

[0028] When clamping and fixing a steel pipe, by rotating the handle 25, the lead screw 24 rotates. With the cooperation of the arc-shaped slide rail 21, the movable seat 22 drives the rotating ring 28 to move accordingly, so that the position of the rotating ring 28 can be adjusted according to requirements, facilitating the subsequent clamping and fixing of steel pipes of different lengths. After the position adjustment of the rotating ring 28 is completed, when clamping, the pneumatic cylinder 29 operates to drive the arc-shaped clamping plates 30 to approach each other, so that the steel pipe can be clamped and fixed, avoiding the phenomenon of the steel pipe shifting during the cutting process, and realizing the precise cutting operation of the steel pipe; after the steel pipe is clamped and fixed, when cutting, under the action of the second motor 19, the gear 20 drives the annular rack 18 to rotate, and then the clamped and fixed steel pipe also rotates accordingly, so that the rotating cutting operation of the steel pipe can be carried out.
