Traditional forming methods can no longer meet the high requirements of these fields for part shape, dimensional accuracy, and surface quality. Therefore, hydraulic steel pipe end extrusion forming technology has emerged and gradually developed into an important forming process. After the hydraulic steel pipe end is extruded, a rust inhibitor is coated on its end to reduce the phenomenon of rusting during subsequent use of the hydraulic pipe. Utility Model Content

[0003] The purpose of this utility model is to provide a hydraulic steel pipe end extrusion molding equipment, which solves the problem of rusting of steel pipes during subsequent use by coating the ends of hydraulic steel pipes with rust inhibitors after extrusion molding.

[0004] This utility model is achieved through the following technical solution:

[0005] This utility model is a hydraulic steel pipe end extrusion forming equipment, including a worktable, an extrusion rust prevention mechanism and a fixing mechanism. A first sliding groove is opened on the surface of the worktable, a first fixing plate is set at one end of the worktable, two first sliding rails are installed on the first fixing plate, a second fixing plate is installed on one side of the worktable, and a storage box is installed on the upper surface of the second fixing plate.

[0006] Furthermore, the extrusion rust prevention mechanism includes a movable plate with two second sliding grooves that slide in conjunction with a first slide rail. The movable plate has a tube end forming block and a fixed block installed on its side wall. A first sleeve is installed at the end of the tube end forming block, and a second sleeve is installed at the end of the fixed block. The second sleeve has four mounting grooves inside and a through hole on one side.

[0007] Furthermore, the extrusion rust prevention mechanism also includes a coating tube with four mounting plates installed on its circumferential wall. The mounting plates are installed inside the mounting groove. A flexible hose is installed on one side of the coating tube and is inserted into the through hole. The end of the flexible hose protruding from the through hole is connected to the storage box.

[0012] This utility model has the following beneficial effects:

[0013] 1. Through the cooperation of the moving plate, the second sleeve, and the coating tube, after the end of the hydraulic pipe is extruded and formed, the moving plate moves to align the end of the second sleeve with the end of the hydraulic steel pipe fixed by the fixing mechanism.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a hydraulic steel pipe end extrusion forming equipment, including a worktable 1, an extrusion rust prevention mechanism 5, and a fixing mechanism 6. The surface of the worktable 1 is provided with a first sliding groove 101, and a first fixing plate 2 is provided at one end of the worktable 1. The first fixing plate 2 is equipped with two first sliding rails 201. A second fixing plate 3 is installed on one side of the worktable 1, and a storage box 4 is installed on the upper surface of the second fixing plate 3. The storage box 4 contains rust prevention liquid. After the hydraulic steel pipe end is extruded and formed, the pipe end is coated with rust prevention liquid to prevent the hydraulic steel pipe from rusting during subsequent use.

[0023] The extrusion rust-preventing mechanism 5 includes a movable plate 501, which has two second sliding grooves 502 that slide in conjunction with a first slide rail 201. A tube end forming block 503 and a fixed block 505 are mounted on the side wall of the movable plate 501. A first sleeve 504 is mounted on the end of the tube end forming block 503, and a second sleeve 506 is mounted on the end of the fixed block 505. The second sleeve 506 has four mounting grooves 507 inside, and a through hole 508 is provided on one side of the second sleeve 506, connecting to the round hole 512. The output shafts of the internal and external power sources are compatible, so the external power source can drive the moving plate 501, causing the moving plate 501 to move on the surface of the first slide rail 201 through the second slide groove 502. The tube end forming block 503 has a round hole adapted to the tube end of the steel pipe. When the tube end of the steel pipe is aligned with the round hole, the tube end of the steel pipe is driven into the interior of the first sleeve 504 by the movement of the fixed block 601. When the tube end of the steel pipe is aligned with the round hole of the tube end forming block 503, the tube end is extruded and formed by the continuous movement of 601.

[0024] The extrusion rust prevention mechanism 5 also includes a coating tube 509. Four mounting plates 510 are installed on the circumferential wall of the coating tube 509. The mounting plates 510 are installed inside the mounting groove 507. A hose 511 is installed on one side of the coating tube 509. The hose 511 is inserted into the through hole 508. One end of the hose 511 protruding from the through hole 508 is connected to the storage tank 4. A through hole 508 is opened on one side of the second sleeve 506. After the end of the hydraulic pipe is extruded and formed, the movement of the moving plate 501 makes the end of the second sleeve 506 align with the end of the hydraulic steel pipe fixed by the fixing mechanism 6. Then, the movement of the fixing block 601 makes the end of the pipe move into the second sleeve 506. When the end of the pipe enters the second sleeve 506, since the coating tube 509 provides rust prevention liquid from the inside of the storage tank 4 through the hose 511, the mounting groove 507 coats the end of the hydraulic steel pipe, thereby preventing rust on the end of the hydraulic steel pipe after it is extruded and formed.

[0025] The fixing mechanism 6 includes a fixing block 601. A second slide rail 605 is installed at the bottom of the fixing block 601, and the second slide rail 605 slides in conjunction with the first slide groove 101. The fixing block 601 has a fixing hole 604. Two connecting plates 603 are installed at one end of the fixing block 601. The connecting plates 603 have threaded holes 608. A threaded rod 607 is threadedly connected inside the threaded hole 608. A clamping block 606 is installed at one end of the threaded rod 607 that passes through the threaded hole 608. Before the hydraulic steel pipe end is extruded and formed, the user inserts the hydraulic steel pipe into the fixing hole 604 to fix the hydraulic steel pipe inside the fixing block 601. Then, the connecting groove 602 is connected to the output shaft of the external power source to fix the pipe. The fixed block 601 slides on the surface of the first slide groove 101 via the second slide rail 605, and the moving plate 501 moves on the surface of the first slide rail 201 via the second slide groove 502, so that the end of the first sleeve 504 is aligned with the end of the hydraulic steel pipe. At this time, the end of the hydraulic steel pipe moves into the inside of the first sleeve 504 until the end of the pipe abuts against the side wall of the end forming block 503, thereby extruding and forming the end of the hydraulic steel pipe. When encountering a small diameter hydraulic pipe, the threaded rod 607 can be rotated to bring the two clamping blocks 606 closer together, thereby fixing the hydraulic pipe and preventing failure of the end extrusion forming due to unstable fixing when encountering a small diameter hydraulic pipe.

[0026] The movable plate 501 has a connecting hole 512, and the inside of the connecting hole 512 is adapted to the output shaft of the external power source.

[0027] The fixed block 601 has a connecting groove 602, and the inside of the connecting groove 602 is adapted to the output shaft of the external power source.

[0028] The clamping block 606 is semi-circular, and the coating tube 509 is made of soft material or sponge material.
