[0002] Microtubes refer to pipes with smaller diameters. During processing, microtubes require bending tools to bend the microtubes into bends of different degrees at different positions according to different usage requirements, so that they can be used in different situations.
[0003] When using the bending tool, the position where the microtube needs to be bent is clamped on the pipe positioning block, and the bending head is pushed to rotate so that one side of the microtube fits against one end of the extrusion block and bends. However, when the microtube requires different bending radius, the positioning block and extrusion block of the tool need to be removed and replaced, resulting in low processing efficiency when a single batch of microtube bending work has different bending requirements. Utility Model Content

A micro-tube bending tool is proposed.

[0006] The effect achieved by the above components is: by setting the first screw, when using the bending tool, the microtube is placed on the surface of the base between the extrusion block and the positioning block, and then the electric telescopic rod is extended to move the extrusion block to clamp the microtube between the extrusion block and the positioning block, and then the push rod is manually pushed to rotate to move the bending block on the surface of the microtube and push the microtube to bend at one end of the positioning block and the slider in the direction of rotation of the push rod, and the rotation distance of the push rod is controlled to adjust the bending angle of the microtube. When the bending radius of the tool for the microtube needs to be adjusted, the first screw can be rotated to control the T-shaped block to move on the outer surface of the first screw and the inner wall of the slide groove, and the slider is driven by the T-shaped block to move to change the distance between the slider and the positioning block and fix it, and the spacing between the slider and the positioning block is adjusted so that the microtube presents different bending radii when bending through the surface of the slider and the positioning block.
[0007] Preferably, one side of the positioning block is fixedly connected to a round rod, and the sliding block slides on the outer surface of the round rod.
[0008] The effect achieved by the above components is that when the microtube bends through the surface of the slider and causes force to be applied to one end of the slider, the angle between the slider and the positioning block can be further limited by the round rod, thereby avoiding as much as possible the deviation of the position caused by the force applied to one end of the slider.
[0009] Preferably, the bottom end of the sliding block is fixedly connected to a rectangular block, and the bottom end of the rectangular block slides on the outer surface of the base.
[0010] The effect achieved by the above components is: when the first screw is rotated to control the movement of the slider, the bottom end of the rectangular block will slide on the outer surface of the base.

[0011] Preferably, one end of the sliding block and the positioning block is fixedly connected with a bending piece, and the bending piece is made of rubber material.
[0012] The effect achieved by the above components is that by providing the curved piece made of rubber, the microtube is not likely to slide up and down when one side contacts the slider and the positioning block provided with the curved piece.
[0013] Preferably, one end of the first screw rod away from the base is fixedly connected to a disc, and one side of the disc is rotatably connected to a handle.

[0016] The effect achieved by the above components is: when bending the microtube, after placing the microtube on the surface of the base, the groove ring can be pushed to rotate so that the groove ring moves downward on the outer surface of the second screw to adjust the height position of the pressure rod, and then the pressure rod is pushed to make the circular ring rotate on the outer surface of the groove ring to press the pressure rod on the upper side of the microtube. The position of the microtube on the base surface is further restricted by the pressure rod, and it is avoided as much as possible that the microtube is close to the extrusion block and the other end is tilted upward after the force is applied, which affects the bending effect of the microtube.
[0017] Preferably, two pads are fixedly connected to the bottom edge of the pressure rod, and the two pads are made of rubber material.
[0018] The effect achieved by the above components is that by providing the rubber pad, the edge of the bottom end of the pressure rod is less likely to cause wear on the surface of the microtube when the bottom end of the pressure rod presses on the surface of the microtube.
[0019] Preferably, a plurality of protrusions are fixedly connected to the top end of the groove ring, and the protrusions are distributed in a circular pattern on the outer surface of the groove ring.
[0020] The effect achieved by the above components is that the groove ring can be pushed to rotate more conveniently by pressing the protrusion on the top of the groove ring with the hand without slipping.

The rotation distance of the push rod 6 is controlled to adjust the bending angle of the microtube. When it is necessary to adjust the bending radius of the tooling on the microtube, the first screw 22 can be rotated to control the T-shaped block 24 to move on the outer surface of the first screw 22 and the inner wall of the slide 21. The slider 23 is driven by the T-shaped block 24 to move and change the distance between it and the positioning block 8 and fix it. The distance between the slider 23 and the positioning block 8 is adjusted so that the microtube presents different bending radii when bending on the surface of the slider 23 and the positioning block 8.
[0029] Reference Figure 2-3As shown, in this embodiment: a round rod 26 is fixedly connected to one side of the positioning block 8, and the slider 23 slides on the outer surface of the round rod 26. When the microtube bends through the surface of the slider 23 so that one end of the slider 23 is subjected to force, the round rod 26 can further limit the angle between the slider 23 and the positioning block 8, and avoid as much as possible the position deviation caused by the force on one end of the slider 23.

Holding the outer surface of the grip rod 29 can more conveniently push the disc 28 to control the first screw 22 to rotate and adjust the position of the slider 23.
