[0026] Example 1

[0027] See also Figure 1-Figure 4As shown, this embodiment provides a biomedical grade titanium alloy pipe automatic drawing mechanical device, including a workbench 1, a stretching assembly 2 for drawing the pipe is provided on the upper side of the workbench 1, a support plate 3 is installed on one side of the stretching assembly 2 and located on the upper side of the workbench 1, the support plate 3 supports the pipe to be drawn, and a fixing assembly 4 for fixing the pipe is provided on the side of the support plate 3 away from the stretching assembly 2, the fixing assembly 4 fixes the position of the pipe to ensure that the pipe remains stable during the drawing process;

[0028] The fixing assembly 4 includes a transmission assembly arranged on one side of the stretching assembly 2, and the transmission assembly includes a second driving cylinder 411 embedded in the upper side of the workbench 1, so that the second driving cylinder 411 maintains a stable state when in a working state, and the piston rod of the second driving cylinder 411 is fixedly installed with a second telescopic rod 412, and the second telescopic rod 412 is extended under the drive of the second driving cylinder 411, and the end of the second telescopic rod 412 away from the second driving cylinder 411 is connected to a toothed plate 413, and the extended second telescopic rod 412 performs a translational movement in a direction away from the second driving cylinder 411, and the workbench 1 is provided with a notch adapted to the toothed plate 413, and the notch enables the toothed plate 413 to maintain a stable state during the translation process, and the upper side of the toothed plate 413 is meshed with a gear 414, and when the toothed plate 413 translates, the teeth on the toothed plate 413 push the teeth on the gear 414, thereby causing the gear 414 to rotate.

[0029] A U-shaped plate 42 is provided on one side of the support plate 3, and a forward and reverse spiral rod 43 is inserted into the vertical part of the U-shaped plate 42. The U-shaped plate 42 supports the forward and reverse spiral rod 43 so that the forward and reverse spiral rod 43 always remains stable, and the opposite ends of the forward and reverse spiral rod 43 extend to the outer wall of the U-shaped plate 42, and the forward and reverse spiral rod 43 are in contact with the U-shaped plate 42 and extend to the outer wall of the U-shaped plate 42 are smooth. One end of the forward and reverse spiral rod 43 close to the second driving cylinder 411 is fixedly connected to the gear 414, and the forward and reverse spiral rod 43 rotates under the drive of the gear 414, and the smooth part of the forward and reverse spiral rod 43 allows the forward and reverse spiral rod 43 to rotate normally.

[0030] The opposite ends of the forward and reverse spiral rods 43 are partially sleeved with limit plates 44 located inside the U-shaped plate 42. The contact parts between adjacent limit plates 44 and the forward and reverse spiral rods 43 are spiral. When the forward and reverse spiral rods 43 rotate, they are movably connected to the vertical part of the U-shaped plate 42 through the smooth part to keep the original position immovable, and the forward and reverse spiral rods 43 drive the adjacent limit plates 44 to move in opposite directions along the spiral trajectory. Baffles 45 are installed on the opposite side walls of adjacent limit plates 44. The limit plates 44 drive the baffles 45 to move together, that is, the adjacent baffles 45 move in opposite directions. The baffles 45 are arc-shaped and have smooth inner walls. The arc-shaped baffles 45 are easier to fit the pipe and can better fix the pipe.

[0031] The support plate 3 is provided with a circular hole for the pipe to pass through, and an oil tank is installed on the upper side of the support plate 3. Lubricating oil is stored in the oil tank, and a dropper is installed on the side of the oil tank close to the workbench 1. The lubricating oil is dripped onto the pipe through the dropper. The lubricating oil can form a lubricating film on the metal surface during the pipe drawing process to avoid direct contact between the pipe and the drawing die, thereby reducing friction and wear, and reducing scratches on the die surface. An oil storage box is installed on the upper side of the workbench 1 and directly below the dropper. During the pipe drawing process, the excess lubricating oil will drip into the oil storage box due to the contact between the pipe and the circular hole of the support plate 3, which can be reused while preventing the lubricating oil from dripping onto the workbench 1, making the workbench 1 difficult to clean.

The pad supports the first driving cylinder 21 so that the first driving cylinder 21 remains stable when in working state. The piston rod of the first driving cylinder 21 is connected to a first telescopic rod 22. The first driving cylinder 21 is started to drive the first telescopic rod 22 to shorten. A slide plate 23 is installed at one end of the first telescopic rod 22 close to the support plate 3. The shortened first telescopic rod 22 drives the slide plate 23 toward the direction of the first driving cylinder 21. For translation, a fixing plate 5 is symmetrically arranged on the upper side of the workbench 1, and the fixing plate 5 supports the slide plate 23. The opposite side walls of the adjacent fixing plates 5 are provided with protrusions, and the slide plate 23 is provided with a groove adapted to the protrusions. The protrusion of the fixing plate 5 is engaged with the groove of the slide plate 23, thereby providing a track for the movement of the slide plate 23, so that the slide plate 23 can move smoothly. An adsorption plate 24 is installed on the upper side of the slide plate 23, and one side wall of the adsorption plate 24 close to the supporting plate 3 is evenly coated with an adsorbent, and the titanium alloy pipe and the adsorbent are physically combined by the van der Waals force, thereby adsorbing the pipe.
