Description

Technical Field

[0001] The utility model specifically relates to a full-automatic stretching and cutting all-in-one machine. Background Art

[0002] With the development of society and advancements in science and technology, pipe fittings are moving towards higher strength and higher toughness. The quality requirements for pipe fittings are constantly increasing, and pipe manufacturing technology and equipment are also constantly evolving. Among them, pipe end forming machines are widely used in pipe manufacturing. They are used to form the ends of pipe fittings. They are suitable for forming various shapes of pipe splices, automotive oil pipes, air ducts, water pipes, and air conditioning pipe connections.

[0003] At present, pipe fittings need to go through the processes of stretching and cutting during processing. However, in the existing technology, each process needs to be carried out on different machines, and it is impossible to complete the processing from raw materials to finished products with only one device. That is, the pipe fittings are first stretched by manual loading and then manually transferred to the cutting machine for cutting. Not only is the processing process cumbersome, but each processing process requires manual auxiliary operations, which requires more workers, increases labor intensity, low production efficiency, and increases production costs.

[0035] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0036] Example

[0037] like Figure 1-11As shown, a fully automatic stretching and cutting machine includes a workbench 1, an assembly frame 2 fixedly installed above the workbench 1 by bolts, a tube transfer mechanism 3 fixedly installed inside the assembly frame 2 by bolts, a tube loading mechanism 4 fixedly installed on one side of the workbench 1, a tube stretching mechanism 5 fixedly installed above the tube loading mechanism 4 and cooperating with the tube loading mechanism 4, a tube positioning mechanism 6 fixedly installed above the tube loading mechanism 4 and located on one side of the tube stretching mechanism 5, a tube mouth cutting mechanism 7 fixedly installed above the tube loading mechanism 4 and located on one side of the tube positioning mechanism 6, and a blanking guide plate 8 fixedly installed above the tube loading mechanism 4 and located on the side of the tube mouth cutting mechanism 7.

[0038] The pipe transfer mechanism 3 includes a hanging plate 31 with guide rails fixed to the assembly frame 2 by bolts, a hanging slide 32 mounted in cooperation with the guide rails on the hanging plate 31 via sliders, a translation cylinder 33 fixed to the hanging plate 31 by bolts and with its output end fixed to the hanging slide 32, a profile frame 34 fixedly mounted below the hanging slide 32, and a gripping robot 35 equidistantly mounted on the profile frame 34.

[0039] The gripping manipulator 35 includes a hoisting cylinder 351 fixedly mounted on the profile frame 34, a clamping cylinder 352 fixedly mounted on the output end of the hoisting cylinder 351, and a pipe body chuck 353 assembled on the output end of the clamping cylinder 352. Specifically, the gripping manipulator 35 is provided with four, which can lift and lower the clamping cylinder 352 through the hoisting cylinder 351, so that the clamping cylinder 352 can drive the pipe body chuck 353 to clamp the pipe body. Therefore, the pipe body transfer mechanism 3 drives the hoisting slide 32 to perform reciprocating translation movement through the translation cylinder 33, thereby driving the gripping manipulator 35 on the profile frame 34 to perform regular translation movement of the pipe body workpiece. The specific process of transferring the tube workpiece is that the first clamping robot clamps the tube workpiece on the tube loading mechanism 4 to the tube stretching mechanism 5 for stretching processing, the second clamping robot clamps the stretched tube workpiece on the tube stretching mechanism 5 to the tube positioning mechanism 6 for repositioning to avoid the tube workpiece being blocked during the next conveying process, the third clamping robot clamps the newly positioned tube workpiece from the tube positioning mechanism 6 to the pipe mouth cutting mechanism 7 for end cutting processing, and the fourth clamping robot conveys the cut tube workpiece on the pipe mouth cutting mechanism 7 to the unloading guide plate 8, so that the tube workpiece is discharged through the unloading guide plate 8.

[0040] The tube loading mechanism 4 includes a lower shell 41 fixedly mounted on the workbench 1, an upper shell 42 fixedly mounted on the lower shell 41 by bolts and used to store the tube workpiece, a first loading cylinder 43 fixedly mounted on the inner side of the lower shell 41, a first ejection plate 44 fixedly mounted on the first loading cylinder 43 and passing through the upper shell 42 to eject the tube workpiece, a second loading cylinder 45 fixedly mounted on the inner and outer sides of the lower shell 41, a second ejection plate 46 fixedly mounted on the second loading cylinder 45 and passing through the upper shell 42 to eject the tube workpiece, a steel pipe rack 47 fixedly mounted above the upper shell 42 and corresponding to the first ejection plate 44, a material blocking telescopic cylinder 48 equidistantly mounted on the steel pipe rack 47, and a tube workpiece pushing mechanism 49 fixedly mounted above the upper shell 42 and corresponding to the second ejection plate 46.

[0041] The upper shell 42 is provided with an inclined tube workpiece support plate 421 between the first ejection plate 44 and the second ejection plate 46. Specifically, it can receive the first ejection plate 44 to push the tube workpiece from the feeding end of the upper shell 42, and then fall into the tube workpiece support plate 421 to wait for the second ejection plate 46 to push it up again for feeding;

[0042] The lower end of the stopper telescopic cylinder 48 is provided with an L-shaped baffle 481, which can specifically block excess pipe workpieces and limit the pipe workpieces that the first ejector plate 44 ejects from the upper shell 42 to one at a time;

[0043] The tube workpiece pushing mechanism 49 includes a transverse guide rod 491 with a guide track groove fixedly mounted on the upper shell 42, a pushing positioning cylinder 492 fixedly mounted on one end of the transverse guide rod 491, and a pushing positioning plate 493 fixedly mounted on the output end of the pushing positioning cylinder 492 and extending to above the second ejection plate 46. Specifically, it can push the tube workpiece above the second ejection plate 46 forward so that it is close to the loading position of the tube stretching mechanism 5, making it convenient for the clamping robot 35 to clamp and transfer it to the tube stretching mechanism 5 for stretching processing.

[0044] The tube stretching mechanism 5 includes a stretching base 51 fixedly mounted on the workbench 1, a large guide column 52 fixedly mounted on the stretching base 51, a stretching head 53 mounted on the large guide column 52, a transmission screw 54 mounted on the stretching base 51 and passing through the stretching head 53, a screw drive motor 55 installed below the stretching base 51 and connected to the transmission screw 54 through a belt, a tube workpiece feeding rack 56 mounted on the large guide column 52, and a positioning clamp 57 fixedly mounted on the workbench 1 and fixedly mounted on the large guide column 52.

[0045] An auxiliary support plate 511 is installed on the side of the stretching base 51 facing the stretching head 53, which can cooperate with the installation of the pipe workpiece feeding rack 56;

[0046] Two small guide posts 531 are fixedly mounted on the stretching head 53. The other ends of the small guide posts 531 pass through the auxiliary support plate 511. A support plate 532 with a V-shaped groove is mounted near the stretching head 53. A U-shaped groove 533 is formed in the middle of the upper end of the stretching head 53, and a pad 534 with an annular groove is mounted in the U-shaped groove 533 to support the tubular workpiece. Side pressure cylinders 535 are fixedly mounted on both sides above the U-shaped groove 533 and inclined at 45 degrees. A tube pressing die 536 is fixedly mounted at the output end of the side pressure cylinder 535 and can cooperate with the pad 534 to fix the tube workpiece.

[0047] The transmission screw 54 passes through one end of the stretching base 51 and is equipped with a pulley 541, which can be connected to the screw drive motor 55 through a belt;

[0048] The tube workpiece feeding rack 56 includes a translation plate 561 movably mounted on the large guide column 52, with a hollowed-out lower center portion; a push rod 562 located in the middle of the upper end of the translation plate 561 and passing through the translation plate 561; a triangular top plate 563 fixedly mounted at the end of the push rod 562 and having a clearance fit with the support plate 532; and a feeding cylinder 564 fixedly mounted on the auxiliary support plate 511, with the output end connected to the push rod 562 via a shaft sleeve.

[0049] The positioning clamp 57 includes a base 571 fixedly mounted on the workbench 1 and fixedly mounted on the large guide column 52, a fixed clamping block 572 fixedly mounted on the base 571, a lifting cylinder 573 assembled above the base 571 through a cylinder, a movable clamping block 574 fixedly mounted below the lifting cylinder 573, and a ejecting cylinder 575 mounted on one side of the base 571 for ejecting the workpiece through the tube body.

[0050] Specifically, the first gripping manipulator clamps the pipe workpiece on the pipe loading mechanism 4 to the pipe workpiece feeding rack 56 inside the pipe stretching mechanism 5. At this time, the side pressure cylinder 535 and the lifting cylinder 573 are opened, and the feeding cylinder 564 drives the pushing rod 562 to make the triangular top plate 563 push the pipe workpiece on the supporting plate 532 forward, so that its head end passes through the stretching head 53 and enters the positioning clamp seat 57. Then the lifting cylinder 573 is controlled to press down the movable clamp block 574 to cooperate with the fixed clamp block 572 to tighten the pipe workpiece. At the same time, the side pressure cylinder 535 is also started. The tube body workpiece is stretched, and the side pressure cylinder 535 and the lifting cylinder 573 are opened, and the stretched tube workpiece is pushed out by the ejecting cylinder 575, so that the second clamping robot can clamp the stretched tube workpiece on the tube stretching mechanism 5 to the tube positioning mechanism 6 for repositioning.

Specifically, the forward pushing cylinder 63 can push the tube body workpiece placed on the supporting plate 64 forward and be blocked by the limiting baffle 65, so that the position of the tube body workpiece is conducive to the third clamping robot clamping the tube body positioning mechanism 6 from the newly positioned tube body workpiece to the pipe mouth cutting mechanism 7 for end cutting processing.

[0052] The pipe mouth cutting mechanism 7 includes a cutting base 71 fixed to the workbench 1 and with a guide rail, a clamp 72 fixedly installed on the cutting base 71 and with a built-in cylinder, a cutting translation table 73 assembled above the cutting base 71 through a slider cooperating with the guide rail, a position adjusting cylinder 74 fixedly installed on one side of the cutting base 71 and with the output end fixedly connected to the cutting translation table 73, a support column 75 fixedly installed on the cutting base 71, a fixed support plate 76 with a slide bar installed above the support column 75 by bolts, a downward pressure cylinder 77 fixedly installed above the fixed support plate 76, a lifting plate 78 assembled on the fixed support plate 76 through a slider cooperating with the slide bar and with the upper end fixed to the output end of the downward pressure cylinder 77, and a cutting motor 79 fixedly installed below the lifting plate 78.
