Description

Technical Field

[0001] This utility model relates to the field of pipe bending machines, and in particular to a pipe bending machine with a straight arm for steel pipe processing. Background Technology

[0002] The bending arm and straight pusher are the core working components of the pipe bending machine. The bending arm and straight pusher (also known as the movable pusher or bending rocker arm) is the mechanical arm in the pipe bending machine that directly contacts the pipe and pushes it to bend. It is responsible for directly applying pushing or rotational force to make the pipe plastically deform along the mold.

[0003] The bending arm of a pipe bending machine can transmit power to the pipe through hydraulic or electric drive, so that it conforms to the curvature of the bending die. Existing bending arm straight-acting structures generally control the movement of the clamping seat through a hydraulic structure to perform pipe bending processing. However, the hydraulic mechanism has low precision, and during use, the movement distance of the clamping seat is prone to deviation from the set distance, resulting in low pipe bending precision, which is not conducive to pipe bending processing. Utility Model Content

[0004] In view of this, the present invention provides a bending arm straight-pull structure for a pipe bending machine for steel pipe processing. The main technical problem to be solved is: to provide a bending arm straight-pull structure for a pipe bending machine that can automatically and with high precision adjust the position.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a pipe bending machine for steel pipe processing with a straight bending arm, comprising a frame, a track fixedly connected to the top of the frame, a motor fixedly connected to the left side of the frame, a reducer fixedly connected to the top of the motor, a hollow channel provided inside the reducer, a lead screw nut fixedly connected to the left side of the hollow channel of the reducer, a lead screw installed inside the lead screw nut, a clamping seat movably connected to the top of the track, and the end of the lead screw away from the lead screw nut fixedly connected to the right side wall of the clamping seat.

[0006] By adopting the above technical solution, the motor and reducer work together to drive the lead screw nut to rotate, thereby controlling the lead screw inside the lead screw nut to move horizontally back and forth. During the movement of the lead screw, the clamping seat moves back and forth on the track, so that the clamping seat can apply a thrust to the pipe, causing the pipe to undergo plastic deformation along the mold. At the same time, the cooperation between the motor and the reducer can accurately control the number of rotations of the lead screw nut, thereby accurately controlling the movement distance of the lead screw, which is beneficial to improving the bending accuracy of the pipe and facilitating the pipe bending process.

[0007] As a further description of the above technical solution:

[0008] A fixing block is fixedly connected to the top of the frame, and the lead screw nut is movably installed inside the fixing block.

[0009] By adopting the above technical solution, the lead screw nut is confined inside the fixed block and can rotate inside the fixed block.

[0010] As a further description of the above technical solution:

[0011] The fixing block is located at the right end of the track, and the position of the lead screw corresponds to the position of the hollow channel.

[0012] By adopting the above technical solution, when the lead screw nut rotates, the internal lead screw will move horizontally. When the lead screw moves to the right, the right end of the lead screw will enter the hollow channel, which facilitates the movement of the lead screw.

[0013] As a further description of the above technical solution:

[0014] The right side wall of the clamping seat is provided with reinforcing ribs.

[0015] By adopting the above technical solution, the strength of the clamping seat is increased.

[0016] As a further description of the above technical solution:

[0017] The left side wall of the clamping seat is provided with a slot, and a mold is movably installed in the slot.

[0018] By adopting the above technical solution, the clamping seat can provide horizontal thrust to the pipe, enabling the pipe to undergo plastic deformation along the mold.

[0019] By employing the above technical solution, the pipe bending machine for steel pipe processing of this utility model has at least the following beneficial effects:

[0020] 1. Compared with the prior art, the bending arm of this steel pipe processing bending machine is straight and pushes. The motor and reducer work together to drive the screw nut to rotate, thereby controlling the screw inside the screw nut to move horizontally back and forth. During the movement of the screw, the clamping seat will control the clamping seat to move back and forth on the track, so that the clamping seat can apply a pushing force to the pipe and make the pipe plastically deform along the mold.

[0021] 2. Compared with the existing technology, this pipe bending machine for steel pipe processing has a straight bending arm. Through the cooperation of the motor and the reducer, it can accurately control the number of rotations of the screw nut, thereby accurately controlling the movement distance of the screw. This is beneficial to improving the bending accuracy of the pipe and facilitating the pipe bending process. Attached Figure Description

[0027] Reference Figure 1-3 This utility model provides a pipe bending machine for steel pipe processing with a straight bending arm: it includes a frame 1, a rail 2 fixedly connected to the top of the frame 1, a motor 3 fixedly connected to the left side of the frame 1, and a reducer 4 fixedly connected to the top of the motor 3. The reducer 4 is a worm gear reducer, which can be an MVRV063 worm gear reducer or other types of reducers. The reducer 4 has a hollow channel inside. A fixing block 5 is fixedly connected to the top of the frame 1. A lead screw nut 6 is movably installed inside the fixing block 5. The lead screw nut 6 is confined inside the fixing block 5 and can rotate inside the fixing block 5. The lead screw nut 6 is fixedly connected inside the left side of the hollow channel of the reducer 4. An internal lead screw 7 is installed, and a clamping seat 8 is movably connected to the top of the track 2. The end of the lead screw 7 away from the lead screw nut 6 is fixedly connected to the right side wall of the clamping seat 8. During use, the motor 3 and the reducer 4 work together to drive the lead screw nut 6 to rotate, thereby controlling the lead screw 7 inside the lead screw nut 6 to move horizontally back and forth. During the movement of the lead screw 7, it controls the clamping seat 8 to move back and forth on the track 2, so that the clamping seat 8 can apply a pushing force to the pipe, causing the pipe to undergo plastic deformation along the mold. At the same time, the cooperation of the motor 3 and the reducer 4 can accurately control the number of rotations of the lead screw nut 6, thereby accurately controlling the moving distance of the lead screw 7, which is beneficial to improving the bending accuracy of the pipe and facilitating the pipe bending process.

[0028] The fixing block 5 is located at the right end of the track 2. The position of the lead screw 7 corresponds to the position of the hollow channel. When the lead screw nut 6 rotates, the lead screw 7 inside will move horizontally. When the lead screw 7 moves to the right, the right end of the lead screw 7 will enter the hollow channel to facilitate the movement of the lead screw 7.

[0029] The right side wall of the clamping seat 8 is provided with reinforcing ribs to increase the strength of the clamping seat 8. The left side wall of the clamping seat 8 is provided with a slot, in which a mold is movably installed, so that the clamping seat 8 can provide horizontal thrust to the pipe, allowing the pipe to undergo plastic deformation along the mold.

[0030] Working principle: The motor 3 and the reducer 4 work together to drive the lead screw nut 6 to rotate, thereby controlling the lead screw 7 inside the lead screw nut 6 to move horizontally back and forth. During the movement of the lead screw 7, the clamping seat 8 will control the clamping seat 8 to move back and forth on the track 2, so that the clamping seat 8 can apply a pushing force to the pipe, causing the pipe to undergo plastic deformation along the mold.
