[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example 1, please refer to Figures 1 to 4The utility model provides a technical solution: a magnesium alloy tube drawing machine that prevents falling off during processing, including a tube drawing machine body 1, a slide rail 101 is opened inside the tube drawing machine body 1, and a first slider 102 is slidably connected to the inner surface of the slide rail 101, and a multi-section electric push rod 103 is fixedly installed on the left side of the first slider 102, and the other end of the multi-section electric push rod 103 is fixedly installed on the left side of the inner part of the slide rail 101. The two forward screw rods 110 are fixedly installed, and the right sides of the two forward screw rods 110 are fixedly installed with reverse screw rods 111. The right outer surfaces of the two reverse screw rods 111 are movably embedded in the right inner side of the connecting plate 104. The outer surfaces of the two forward screw rods 110 and the two reverse screw rods 111 are threadedly connected with second sliders 112. The inner sides of the four second sliders 112 are fixedly installed with first hinges 114. The top two sides of the connecting plate 104 are provided with first sliding grooves 113. The four second sliding grooves 114 are fixedly installed with first hinges 114. The two sliders 112 are divided into two groups, two by two. The bottom outer surfaces of the two groups of second sliders 112 are slidably connected to the outer surface of the first slide groove 113. The four first hinges 114 are movably connected to the support rods 115 inside, and the other ends of the four support rods 115 are movably connected to the second hinges 116. The four second hinges 116 are divided into two groups, two by two. The other ends of the two groups of second hinges 116 are fixedly installed with splints 117. A second slide groove 118 is provided on the top of the connecting plate 104.

[0031] In this embodiment, personnel can first pick up one end of the magnesium alloy tube and pass it through the tube drawing die 2 inside the tube drawing machine body 1, and place it between the two clamping plates 117, and then start the motor 107 through the power supply system of the motor 107, so that when it is running, it drives the second pulley 108 to rotate through the output shaft, so that when the second pulley 108 rotates, it is transmitted to the first pulley 106 through the belt body 109, and then the first pulley 106 is transmitted to the rotating rod 105, so that when the rotating rod 105 rotates, it can be transmitted to the reverse screw rod 111 through the forward screw rod 110. When the forward screw rod 110 and the reverse screw rod 111 are rotating, they will drive the second slider 112 to slide in the relative direction through the first sliding groove 113, and drive the support rod 115 to flip through the first hinge 114, so that when the support rod 115 flips, it can push the clamping plate 117 to slide inward through the second sliding groove 118 through the second hinge 116. After sliding to a certain extent, the splint 117 will fit the outer surface of the magnesium alloy tube and clamp it. Then, the personnel will start the multi-section electric push rod 103 through the power supply system of the multi-section electric push rod 103, so that when it shrinks, it can pull the first slider 102 to slide to the left through the slide rail 101, and pull the magnesium alloy tube to slide to the left inside the tube drawing mold 2 through the connecting plate 104, thereby performing the tube drawing operation on the magnesium alloy tube. The arrangement of the forward-rotating screw rod 110 and the splint 117 structure can not only make the splint 117 fit the outer surface of the magnesium alloy tube accurately, ensuring that the magnesium alloy tube will not move or fall off during the drawing process, but also the symmetrical transmission design of the forward-rotating screw rod 110 and the reverse-rotating screw rod 111 ensures that the two splints 117 provide uniform and consistent clamping force. The uniform clamping force can effectively prevent the magnesium alloy tube from falling off when it is locally too tight or too loose, thereby improving the stability of the magnesium alloy tube during the drawing process, thereby preventing the risk of falling off.

[0032] Example 2, as Figures 1 to 4 As shown, the bottom outer surfaces of the two splints 117 are slidably connected to the inner surface of the second slide groove 118, and the tube drawing mold 2 is fixedly embedded on the right side of the inner part of the tube drawing machine body 1. Two movable rods 201 are movably embedded on the right side of the tube drawing machine body 1. The inner sides of the two movable rods 201 are fixedly installed with return springs 202, and the inner surfaces of the two return springs 202 are movably sleeved on the outer surface of the movable rod 201. The other ends of the two return springs 202 are fixedly installed on the outer surface of the movable rod 201. The opposite sides of the two movable rods 201 are fixedly installed with flanges 203, and the interiors of the two flanges 203 are movably embedded with positioning wheels 204.

[0033] In this embodiment, the personnel can first pull the movable rod 201 outward and drive the reset spring 202 to extend, so that when the movable rod 201 moves outward, it can drive the positioning wheel 204 to slide outward synchronously through the flange 203, and then the personnel pick up one end of the magnesium alloy tube so that it is located between the two positioning wheels 204, and embed one end of the magnesium alloy tube into the interior of the tube drawing mold 2. Thereafter, the personnel releases the movable rod 201 and drives the reset spring 202 to reset, so that when the reset spring 202 is reset, it can drive the positioning wheel 204 to slide inward through the movable rod 201 and the flange 203, thereby making the positioning wheel 204 fit the outer surface of the magnesium alloy tube, and through the arrangement of the positioning wheel 204 and the reset spring 202 structure, the personnel can easily align and fix the magnesium alloy tube between the positioning wheels 204, further ensuring the stability of the tube during the tube drawing process.

[0034] Working principle: When in use, personnel can first pick up one end of the magnesium alloy tube and pass it through the tube drawing die 2 inside the tube drawing machine body 1, and place it in the middle of the two splints 117, and then start the motor 107 through the power supply system of the motor 107, so that when it is running, it drives the second pulley 108 to rotate through the output shaft, so that when the second pulley 108 rotates, it is transmitted to the first pulley 106 through the belt body 109, and then the first pulley 106 is transmitted to the rotating rod 105, so that when the rotating rod 105 rotates, it can be transmitted to the reverse screw rod 111 through the forward screw rod 110. When the forward screw rod 110 and the reverse screw rod 111 are rotating, they will drive the second slider 112 to slide in the relative direction through the first slide groove 113, and drive the support rod 115 to flip through the first hinge 114, so that when the support rod 115 flips, it can push the splint 117 through the second slide groove 118 to slide inward through the second hinge 116. After 17 slides to a certain extent, the splint 117 will fit the outer surface of the magnesium alloy tube and clamp it. Then, the personnel will start the multi-section electric push rod 103 through the power supply system of the multi-section electric push rod 103, so that when it shrinks, it can pull the first slider 102 to slide to the left through the slide rail 101, and pull the magnesium alloy tube to slide to the left inside the tube drawing mold 2 through the connecting plate 104, thereby performing the tube drawing operation on the magnesium alloy tube. The arrangement of the forward-rotating screw rod 110 and the splint 117 structure not only enables the splint 117 to accurately fit the outer surface of the magnesium alloy tube, ensuring that the magnesium alloy tube will not move or fall off during the drawing process, but also the symmetrical transmission design of the forward-rotating screw rod 110 and the reverse-rotating screw rod 111 ensures that the two splints 117 provide uniform and consistent clamping force. The uniform clamping force can effectively prevent the magnesium alloy tube from falling off when it is locally too tight or too loose, thereby improving the stability of the magnesium alloy tube during the drawing process, thereby preventing the risk of falling off. During use, personnel can first pull the movable rod 201 outward and drive the reset spring 202 to extend, so that when the movable rod 201 moves outward, it can drive the positioning wheel 204 to slide outward synchronously through the flange 203, and then the personnel pick up one end of the magnesium alloy tube so that it is located between the two positioning wheels 204, and embed one end of the magnesium alloy tube into the interior of the tube drawing mold 2. After that, the personnel releases the movable rod 201 and drives the reset spring 202 to reset, so that when the reset spring 202 is reset, it can drive the positioning wheel 204 to slide inward through the movable rod 201 and the flange 203, so that the positioning wheel 204 can fit the outer surface of the magnesium alloy tube, and through the arrangement of the positioning wheel 204 and the reset spring 202 structure, personnel can easily align and fix the magnesium alloy tube between the positioning wheels 204, further ensuring the stability of the tube during the tube drawing process.

[0035] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
