Technical Field
[0001] The utility model relates to the technical field of expanding square and rectangular tubes, in particular to a square and rectangular tube end expanding machine. Background Art
[0002] Square tube is a name for square tube and rectangular tube, that is, steel tube with equal and unequal side lengths. It is made by rolling steel strips through process processing. Generally, the steel strips are unpacked, flattened, curled, and welded to form round tubes, which are then rolled into square tubes and cut into required lengths.
[0003] When producing square rectangular tubes, it is sometimes necessary to flare the ends of the square rectangular tubes. When flaring the square rectangular tubes, the square rectangular tubes need to be manually placed on a clamping mechanism, and then flared by starting the flaring mechanism. After the flaring is completed, the square rectangular tubes need to be manually removed, which is inefficient and has certain safety hazards. In addition, when flaring the square rectangular tubes, lubricating oil needs to be sprayed on the pusher end of the flaring mechanism to enable smooth flaring. However, most of the lubricating oil will be squeezed out due to extrusion during flaring, causing it to fall on the workbench, that is, the excess lubricating oil cannot be recovered, and the lubricating oil that has fallen on the workbench needs to be cleaned, which increases the workload.

In the middle of the end, four symmetrically distributed nozzles 532 are fixedly installed in the middle of the conduit 531, four groups of symmetrically distributed springs 522 are fixedly installed at the lower part of the fixed cover 52, and the other ends of the four groups of springs 522 are fixedly installed with limiting beads 523, and two symmetrically distributed second slide grooves 521 are opened at the lower part of the fixed cover 52, and a collecting box 54 is provided at the lower part of the fixed cover 52.

[0020] A first slide groove 211 is provided on the opposite sides of the lower parts of the two baffles 21, and first sliders 131 are fixedly installed at both ends of the support frame 13. The two first sliders 131 are slidably clamped inside the first slide groove 211. By setting the first slide groove 211, the first slider 131 is limited in the first slide groove 211, that is, the support frame 13 is limited, so that when the support frame 13 is driven by the second electric push rod 12 to move up and down, it is more stable.
[0021] Two symmetrically distributed support rods 24 are fixedly installed at the lower part of the back ends of the two baffles 21, and the bottom ends of the four support rods 24 are fixedly installed on the top of the bottom plate 1. By setting the support rods 24, the placement platform 2 is supported and fixed by the support rods 24.
[0022] A limit plate 23 is fixedly installed on one side of the placement platform 2. By setting the limit plate 23, the square tube body 31 sliding down from the placement platform 2 just enters the interior of the placement groove 22 through the limitation of the limit plate 23.
[0023] A fixing block 111 is fixedly installed on the top of one side of the base plate 1 close to the support rod 24, and the bottom end of the first electric push rod 11 is fixedly installed on the top of the fixing block 111. By setting the fixing block 111, the first electric push rod 11 is fixedly installed on the top of the fixing block 111, so that the driving end of the first electric push rod 11 is located on one side of the placement groove 22.
[0024] A square rectangular tube body 31 is provided in the middle of the clamping mechanism 3 . By providing the square rectangular tube body 31 , the clamping mechanism 3 can clamp and fix the square rectangular tube body 31 pushed into the middle of the clamping mechanism 3 by the first electric push rod 11 .
[0025] Four groups of symmetrically distributed limiting grooves 542 are provided on both sides of the two second sliders 541, and the four groups of limiting beads 523 are slidably clamped in the limiting grooves 542. By setting the limiting grooves 542, when the second slider 541 equipped with the collection box 54 is inserted into the second slide groove 521, when it reaches the specified position, the limiting groove 542 also reaches the corresponding position of the limiting beads 523, and the limiting beads 523 are ejected under the reaction force of the spring 522, so that they are clamped in the limiting grooves 542, thereby completing the installation and limit fixation of the collection box 54.
[0026] Working principle: in actual use, the square tube body 31 to be expanded is laid flat on the placement platform 2, and the second electric push rod 12 is started to drive the support frame 13 to the upper end, that is, the push plate 132 is driven to move upward, that is, the square tube body 31 is pushed upward through the placement platform 2 into the placement groove 22, and the square tube body 31 entering the placement groove 22 is pushed out by starting the first electric push rod 11, so that it reaches the middle of the clamping mechanism 3, and the square tube body 31 is clamped and fixed by the clamping mechanism 3, and the end of the square tube body 31 is expanded by the cooperation with the expanding mechanism 5 and the push body 55. After the expansion is completed, the third electric push rod 4 is started to make the unloading rod 41 move upward, thereby pushing the square tube body 31 placed in the clamping mechanism 3 upward. When the square tube body 31 leaves the clamping mechanism 3 as a whole, the unloading rod 41 tilts to one side, causing the square tube body 31 to slide to one side to complete the unloading;
[0027] When the expansion mechanism 5 drives the push body 55 to move toward the square tube body 31, the oil pump 53 is started to extract the lubricating oil inside the oil storage tank 51, and the lubricating oil enters the conduit 531, and is sprayed out by the nozzle 532 in atomized form, so that it is evenly sprayed on one end of the push body 55. When the push body 55 enters the middle part of the square tube body 31, the lubricating oil will flow out due to the squeezing and drip into the inside of the collecting box 54, and the lubricating oil will be collected. The collecting box 54 can be pulled out by pulling the collecting box 54, so as to take out the lubricating oil dropped in the collecting box 54. After the second slider 541 is inserted into the inside of the second slide groove 521, when the limiting groove 542 reaches the relative position of the limiting bead 523, the limiting bead 523 is ejected under the reaction force of the spring 522, and is stuck in the inside of the limiting groove 542, thereby limiting the collecting box 54.
[0028] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
