DETAILED DESCRIPTION

[0025] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0026] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0027] Example: Figure 1-8 As shown, a horizontal fully automatic pipe end forming machine is characterized in that it includes a workbench 1, a pipe feeding mechanism 2 arranged on one side of the workbench 1, a pipe shifting mechanism 3 arranged on one side of the pipe feeding mechanism 2, a pipe end forming mechanism 4 and a pipe axial fixing mechanism 5 arranged on both sides of the pipe shifting mechanism 3, a pipe radial fixing mechanism 6 arranged between the pipe end forming mechanism 4 and the pipe axial fixing mechanism 5, and a pipe end lubricating mechanism 7 arranged on one side of the pipe end forming mechanism 4.

[0029] There are two side baffles 203, which are installed above the feeding platform 201 through sliding rods to ensure that the ends of the steel pipes on the inclined table 202 are aligned. The upper end surface of the ejector plate 205 is inclined toward the discharge track 204, so that the steel pipes can automatically roll toward the discharge track 204. A front baffle is connected between the front end of the discharge track 204 and the inclined table 202. The ejector plate 205 is located on the front side of the front baffle, so that the ejector plate 205 can keep the steel pipe on the top of the ejector plate 205 when jacking up a single steel pipe.

[0030] When feeding, the ejector plate 205 moves upward and lifts a single steel pipe from the inclined table 202; then when the third cylinder 210 extends, the rotating arm 209 drives the rotating shaft 208 to rotate, and the rotating shaft 208 drives the movable gate 207 to flip upward, so that the steel pipe can roll from the top of the ejector plate 205 onto the discharge track 204, and then enter the pipe shifting mechanism 3.

[0031] like Figure 7 and Figure 8 As shown, the pipe shifting mechanism 3 includes a pair of frames arranged between the pipe end forming mechanism 4 and the pipe axial fixing mechanism 5, a chain conveying assembly 303 arranged on each frame, a supporting fork 306 arranged on the chain conveying assembly 303, a transmission shaft 304 arranged at the same end of the two frames and connected between the two groups of chain conveying assemblies 303, and a driving motor 305 for driving the transmission shaft 304 to rotate.

[0032] The frame includes a fixed frame 301 arranged on the side close to the pipe end forming mechanism 4 and a movable frame 302 arranged on the side close to the pipe axial fixing mechanism 5. The fixed frame 301 and the movable frame 302 are parallel and spaced apart. The fixed frame 301 is fixedly arranged near the workbench 1, and the movable frame 302 is installed on the workbench 1 through a slide rail 307 and can move forward and backward relative to the fixed frame 302.

The cross-sectional shape of the transmission shaft 304 is a regular polygon, and the movable seat cover 309 is provided with a regular polygonal sleeve hole matching the cross-sectional shape of the transmission shaft 304. In this embodiment, the cross-sectional shape of the transmission shaft 304 is a regular hexagon, and the sleeve hole on the movable seat cover 309 is also a regular hexagon.

[0034] The workbench 1 is provided with an adjustment assembly 308 for adjusting the distance between the movable frame 302 and the fixed frame 301. The adjustment assembly 308 is connected between the workbench 1 and the movable frame 302, and the adjustment assembly 308 includes adjustment seats 3081 respectively arranged on both sides of the movable frame 302, an adjustment lead screw 3082 rotatably mounted on the adjustment seat 3081, and a lead screw nut 3083 cooperatively mounted on the adjustment lead screw 3082, the lead screw nut 3083 is fixed on the movable frame 302, and the adjustment lead screw 3082 is installed parallel to the lower side of the transmission shaft 304 and is installed on the workbench 1 through the adjustment seat 3081.

[0035] When the adjusting screw 3082 is rotated, the screw nut 3083 moves axially along the adjusting screw 3082, driving the movable frame 302 and the movable seat sleeve 309 to move axially along the transmission shaft 304, thereby adjusting the distance between the two frames.

[0036] The chain conveyor assembly 303 is respectively installed on the two corresponding frames, and the chain conveyor assembly 303 includes a transmission sprocket 3031 arranged at both ends of the frame, a conveyor chain 3032 connected end to end by chain links, and an ear plate 3033 fixedly connected to one side of the chain link, the conveyor chain 3032 is connected to the front and rear transmission sprockets 3031, and the support fork 306 is fixed to the ear plate 3033. A group of chain conveyor assemblies 303 located on the movable frame 3, one of the transmission sprockets 3031 is installed on the movable frame 3 through a bearing seat, and the other transmission sprocket 3031 is coaxially installed on the movable seat sleeve 309, and the movable seat sleeve 309 is installed on the movable frame 302 through a bearing.

[0037] There are multiple support forks 306, eight in this embodiment, which are linearly and evenly spaced on the conveying chain 3032, and forks with upward openings are provided on the support forks 306. The support forks 306 are mounted on the ear plates 3033 by bolts, which is convenient for installation and replacement.

[0038] like Figure 4 , Figure 5 and Figure 6As shown, the tube end forming mechanism 4 includes a first driving element 406 fixed on the workbench 1, a tube shrinking outer mold 401 connected to a first piston rod 407 of the first driving element 406, a tube shrinking inner mold core 402 fixedly arranged in the tube shrinking outer mold 401, a pipe jacking sleeve 409 arranged at the rear end of the tube shrinking inner mold core 402, and a second driving element 410 driving the pipe jacking sleeve 409 to move forward and backward relative to the tube shrinking inner mold core 402, and the pipe jacking sleeve 409 is sleeved between the second mounting seat 405 and the mandrel 404. The tube end forming mechanism also includes a first mounting seat 403 connected to the end of the first piston rod 407, a mandrel 404 connected between the second driving element 410 and the tube shrinking inner mold core 402, and a second mounting seat 405 connected between the first mounting seat 403 and the tube shrinking outer mold 401, the second mounting seat 405 is sleeved on the outer side of the mandrel 404, and the first piston rod 407 and the mandrel 404 are located on the same axis.

[0039] The outer diameter of the jacking sleeve 409 is smaller than or equal to the minimum inner diameter of the outer shrinking mold 401 , and the inner diameter of the jacking sleeve 409 is larger than or equal to the outer diameter of the rear end of the inner shrinking mold core 402 .

[0040] The rear end of the outer tube shrinking mold 401 is provided with a flaring structure to facilitate the end of the jacking sleeve 409 to enter the outer tube shrinking mold 401 .

[0041] The first piston rod 407 is provided with an axially penetrating through hole 408, the second driving element 410 is fixed to the rear side of the first driving element 406, and the second piston rod 411 of the second driving element 410 is inserted into the through hole 408 of the first piston rod 407, the core shaft 404 is fixedly connected to the end of the second piston rod 411 and is coaxially arranged with the second piston rod 411. A push rod 412 is connected between the second piston rod 411 and the top pipe sleeve 409, and the push rod 412 is inserted into the first mounting seat 403.

[0042] There are 4-6 push rods 412, which are evenly distributed along the circumference of the core shaft 404. The end of the second piston rod 411 is provided with a connecting plate for connecting the push rods 412. One end of the push rod 412 is fixed to the connecting plate, and the other end is fixed to the rear end of the top pipe sleeve 409.

[0043] The first driving element 406 and the second driving element 410 are pneumatic cylinders or hydraulic cylinders, and hydraulic cylinders are preferred in this embodiment.

[0044] During shrinking, the first driving element 406 runs, driving the first piston rod 407 to move forward, and the first piston rod 407 pushes the first mounting seat 403 to move forward, so that the outer shrinking tube mold 401 and the inner shrinking tube mold core 402 move forward until the inner shrinking tube mold core 402 extends into the steel pipe and the outer shrinking tube mold 401 is inserted into the end of the steel pipe, completing the shrinking action of the steel pipe.

[0045] After the shrinking action is completed, when the second driving element 410 is in operation, the second piston rod 411 moves forward, pushing the push rod 412 to move, and the push rod 412 pushes the top pipe sleeve 409 to move towards the shrink tube inner mold core 402, so that the end of the top pipe sleeve 409 is against the end of the steel pipe; then the second piston rod 411 moves backward to reset, driving the shrink tube outer mold 401 and the shrink tube inner mold core 402 to move backward. Since the steel pipe is supported by the top pipe sleeve 409 and cannot move with the shrink tube outer mold 401 and the shrink tube inner mold core 402, the steel pipe is separated from the shrink tube outer mold 401 and the shrink tube inner mold core 402.

[0046] like Figure 4 As shown, the pipe axial fixing mechanism 5 includes a pipe jacking seat 503 fixed on the workbench 1, a push rod 502 installed on the pipe jacking seat 503, and a plug 501 installed at the end of the push rod 502. The plug 501 is arranged opposite to the outer tube shrinking mold 401. During the shrinking process, the plug 501 pushes against the other end of the steel pipe to prevent the steel pipe from axially moving after contacting the outer tube shrinking mold 401. The push rod 502 can be installed on the pipe jacking seat 503 by threaded connection, and the distance between the plug 501 and the outer tube shrinking mold 401 can be adjusted by rotating the push rod 502.

[0047] like Figure 4 As shown, the pipe radial fixing mechanism 6 includes lifting blocks 601 disposed on both sides of the pipe displacement mechanism 3, a first cylinder 602 driving the lifting blocks 601 to rise and fall, a movable clamping block 603 disposed between the two lifting blocks 601, a third oil cylinder driving the movable clamping block 603 to rise and fall, and a fixed clamping block 604 fixedly disposed above the movable clamping block 603. When the steel pipe moves to the right below the pipe end forming mechanism 4 and the pipe axial fixing mechanism 5 through the pipe displacement mechanism 3, the pipe displacement mechanism 3 stops running, and at the same time, the lifting block 601 rises to lift the steel pipe located at the station upward, and at the same time, the movable clamping block 603 moves upward to radially fix the steel pipe between the movable clamping block 603 and the fixed clamping block 604, and the next step of shrinking is performed.

[0048] like Figure 8As shown, the tube end lubrication mechanism 7 includes a lubrication seat 701, a lubrication cavity 702 arranged on the lubrication seat 701, an oil injection hole 703 arranged at the upper end of the lubrication seat 701, and an oil storage sponge arranged in the lubrication cavity 702. The lubrication seat 701 is fixed to one side of the shrink tube outer mold 401 and moves synchronously with the shrink tube outer mold 401. The lubrication seat 701 is fixedly mounted on the first mounting seat 403, and the opening of the lubrication cavity 702 faces the direction of the tube feeding mechanism 2. Among them, the projection distance between the lubrication seat 701 and the shrink tube outer mold 401 on the conveying surface of the tube displacement mechanism 3 is equal to the spacing between the two adjacent support forks 306. During the transportation of the steel pipe by the pipe shifting mechanism 3, when the first steel pipe is located directly below the pipe end forming mechanism 4 and the pipe axial fixing mechanism 5, the second steel pipe is located at the station where the pipe end lubrication mechanism 7 is located; after the first steel pipe is lifted and fixed by the pipe radial fixing mechanism 6, the outer tube shrinking mold 401 and the inner tube shrinking mold core 402 move forward to shrink the end of the first steel pipe. At this time, the first mounting seat 403 drives the lubrication seat 701 to move forward with the outer tube shrinking mold 401, so that the second steel pipe extends into the lubrication cavity 702, contacts the oil storage sponge in the lubrication cavity 702, and lubricates the end of the steel pipe. In order to prevent the second steel pipe from moving axially, a fixed baffle is installed on the opposite side of the lubrication seat 701, and the fixed baffle is fixed on the workbench 1. By performing the above-mentioned lubrication operation on the end of the steel pipe, the steel pipe is smoother in the subsequent shrinking process, and the shrinking quality is improved.

[0049] The processing of steel pipe is as follows:

[0050] In the first step, the ejector plate 205 is moved upward to lift a single steel pipe from the inclined table 202; then when the third cylinder 210 is extended, the rotating arm 209 drives the rotating shaft 208 to rotate, and the rotating shaft 208 drives the movable gate plate 207 to flip upward, so that the steel pipe can roll from the top of the ejector plate 205 onto the discharge track 204, so that the steel pipes roll one by one through the discharge track 204 into the corresponding support fork 306 on the pipe shifting mechanism 3;

[0051] In the second step, the conveying chain 3032 moves the distance of one station each time (i.e., the distance between two adjacent support forks 306), so that the first steel pipe moves to the station where the pipe end lubrication mechanism 7 is located. At this time, the first driving element 406 operates to push the first mounting seat 403, the shrink tube outer mold 401 and the lubrication seat 701 to move forward, so that the lubrication seat 701 lubricates the end of the first steel pipe;

[0052] In the third step, the conveying chain 3032 continues to move the distance of one station, so that the first steel pipe moves to the station where the pipe radial fixing mechanism 6 is located, and the second steel pipe moves to the station where the pipe end lubrication mechanism 7 is located, and then the lifting block 601 rises to lift the steel pipe located at the station upward, and at the same time, the movable clamping block 603 moves upward to radially fix the steel pipe between the movable clamping block 603 and the fixed clamping block 604;

[0053] Step 4: The first driving element 406 operates to push the first mounting seat 403, the outer tube shrinking mold 401, the inner tube shrinking mold core 402 and the lubricating seat 701 to move forward, shrinking the end of the first steel tube, and the lubricating seat 701 lubricates the end of the second steel tube;

[0054] Step 5: When the second driving element 410 is running, the second piston rod 411 moves forward, pushing the push rod 412 to move, and the push rod 412 pushes the top pipe sleeve 409 to move toward the shrink tube inner mold core 402, so that the end of the top pipe sleeve 409 is against the end of the steel pipe; then the second piston rod 411 moves backward to reset, driving the shrink tube outer mold 401 and the shrink tube inner mold core 402 to move backward, so that the steel pipe is separated from the shrink tube outer mold 401 and the shrink tube inner mold core 402;

[0055] In the sixth step, the pipe radial fixing mechanism 6 is reset so that the first steel pipe that has completed shrinking re-enters the supporting fork 306 below, and then the second to fifth steps are repeated to continuously shrink the steel pipe.
