Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cutting, in particular to a multi-angle cutting device for steel members. BACKGROUND

[0002] In the field of steel structure processing, steel members (such as steel plates, steel sections, etc.) often need to be cut in multiple types, including straight cutting, angle splicing cutting (such as 45° joint), and edge chamfering, beveling or V-shaped groove processing. Traditional steel member cutting devices usually only have a single direction straight cutting function. When oblique cutting or chamfering processing is needed, the clamping angle of the workpiece must be adjusted manually or by auxiliary equipment, which is tedious and has low positioning accuracy. Especially for long steel members, due to their large weight and poor rigidity, the adjustment process is time-consuming and laborious, and cumulative errors are easily generated.

[0003] In addition, existing devices generally lack integrated angle adjustment mechanisms, and oblique cutting (deflection angle) and chamfering (oblique cutting angle) functions need to be completed by different devices or in separate processes, such as straight cutting with a cutting machine and then moving to a chamfering machine for edge processing. This results in fragmented production processes, multiple equipment occupation, and low production efficiency, making it difficult to meet the needs of modern steel structure manufacturing for efficient, flexible, and integrated processing. SUMMARY

[0004] In order to overcome the inconvenience of adjusting long steel members, the present application provides a multi-angle cutting device for steel members.

[0005] A multi-angle cutting device for steel members includes a cutting table, a plurality of electric push rods symmetrically arranged on the cutting table, a plurality of placement grooves fixed to the moving ends of the electric push rods, a steel member body placed between the placement grooves, a rotating frame connected to the cutting table in the longitudinal direction, a mounting frame connected to the rotating frame in the transverse direction, a cutting machine fixed to the mounting frame, and a handle fixed to the frame of the cutting machine.

[0006] More preferably, it further includes a first indicating block fixed to one side of the mounting frame close to the rotating frame, an arc-shaped first scale fixed to the rotating frame, and the first indicating block pointing to the first scale.

[0007] More preferably, it further includes a support rod rotatably connected to the rotating frame, a sliding block rotatably connected to the support rod, and the sliding block slidably connected to the cutting table, and the sliding block is fixed to the cutting table by a screw.

[0008] More preferably, it further includes a second indicating block fixed to the sliding block, a second scale fixed to one side of the cutting table close to the second indicating block, and the second indicating block pointing to the second scale.

[0009] More preferably, it further comprises elastic pieces distributed in a ring shape, the elastic pieces being fixed to the mounting frame, and a friction surface being arranged on the rotating frame, the elastic pieces being in contact with the friction surface.

[0010] More preferably, it further comprises rolling shafts distributed in a circumferential direction of the rotating frame, the rolling shafts being rotatably connected to the rotating frame, and the rolling shafts being in contact with the mounting frame.

[0011] More preferably, it further comprises a magnetic ring, the magnetic ring being fixed to a side of the cutting table close to the rotating frame, an arc-shaped slot being formed in the magnetic ring, and a magnetic block being slidably connected in the arc-shaped slot, the magnetic block being magnetically attracted to the magnetic ring.

[0012] Compared with the prior art, the present application has the following advantages: the present application can realize straight cutting, deflection bevel cutting, chamfering of bevels and other functions on the same device by controlling the handle to drive the cutting machine to swing left and right in a horizontal plane or to swing left and right in a vertical plane, without moving the steel member, thereby avoiding transferring the workpiece between different devices, reducing the clamping frequency, reducing error accumulation, improving the processing continuity and overall efficiency.

[0013] The present application adopts a mechanical transmission mode in which the supporting rod pushes the sliding block to realize the bevel angle adjustment, and cooperates with the scale to display the angle value in real time, so that the adjustment process is stable, accurate in positioning and convenient for the operator to quickly complete the setting.

[0014] During the left and right swinging of the mounting frame, the elastic pieces are extruded by the friction surface to generate stable damping feeling, so that the adjustment process is smooth and controllable; during cutting, the friction surface is clamped and self-locked by the elastic pieces, so that the mounting frame position can be fixed without manually holding the handle, the tool is effectively prevented from shaking during cutting, and the operation safety and cutting precision are improved.

[0015] When the rotating frame swings left and right, the magnetic block slides along the magnetic ring, and the magnetic attraction force provides moderate resistance, so that the rotating frame can be temporarily positioned at any angle to realize the "hands-off non-falling" random stopping function, and the operator can loosen the screw.

[0027] The specific operation of cutting the steel member is as follows: first, place the steel member body 101 horizontally between the left and right two placing grooves 2, then start the electric push rod 3 and the cutting machine 6, the electric push rod 3 moves backward, so that the placing groove 2 drives the steel member body 101 to move backward to contact the blade of the cutting machine 6, so that the steel member is cut off.

[0028] If the steel member needs to be angle spliced, the cutting direction of the blade of the cutting machine 6 is adjusted (deflection angle, for example, 45° joint of steel structure) before cutting, and the specific operation is as follows: control the handle 7 to make it swing left or right as a whole, the cutting machine 6 drives the mounting frame 5 to swing left or right, and the deflection angle of adjustment can be observed in time by marking the first scale 801 through the first indicating block 8 thereon.

[0029] If the steel member needs to be chamfered, chamfered or V-shaped groove, the cutting angle of the blade of the cutting machine 6 is adjusted (beveling angle, for example, 0°~45° beveling) before cutting, and the specific operation is as follows: unscrew the screw 11, then control the handle 7 to make the rotating frame 4 swing downward to the left or right, the rotating frame 4 drives the sliding block 10 to move left or right through the support rod 9, and the beveling angle of adjustment can be observed in time by marking the second scale 121 through the second indicating block 12 thereon, and the screw 11 is tightened after adjustment.
