Description

Technical Field

[0001] This invention relates to the field of hydraulic press technology, specifically to a horizontal hydraulic press for extruding and punching holes at both ends of a seamless tube. Background Technology

[0002] After the seamless steel pipe is flattened and shaped at both ends, holes are punched in the flattened parts to form a structural form that can be used for connection. This flattening and punching method can achieve a stable connection between the steel pipe and other components through matching fasteners, which is a simple and practical form of steel pipe connection.

[0003] Citing Chinese Patent Publication No. 201510040334.6, a two-cylinder bidirectional hydraulic press includes a frame, which is composed of a control hydraulic station, an upper hydraulic drive element, a lower hydraulic drive element, and a column. The control hydraulic station is installed outside the lower hydraulic drive element and is connected to both the upper and lower hydraulic drive elements. The column is located between the upper and lower hydraulic drive elements and is connected to both the upper and lower hydraulic drive elements by bolts. The upper and lower hydraulic drive elements are positioned correspondingly.

[0004] In seamless tube processing, traditional methods often require multiple machines to complete the flattening and punching processes in stages, resulting in low production efficiency and insufficient precision. Existing hydraulic presses mostly employ vertical structures or single-function designs, which cannot meet the demands of continuous production. For example, some machines are prone to uneven deformation or punching misalignment when processing large-diameter tubes, affecting product quality. There is an urgent need for an integrated, high-precision horizontal hydraulic press to overcome these shortcomings. Summary of the Invention

[0012] Preferably, a cooling mechanism is fixedly connected to the outside of each extrusion die. The cooling mechanism includes a fixed sleeve, which is fixedly connected to the outside of the extrusion die. An air inlet pipe is fixedly connected to the inside of each fixed sleeve, and an air inlet fan is fixedly connected inside each air inlet pipe.

[0013] Preferably, each of the fixed sleeve boxes is movably connected to an air outlet box, and each air outlet box is fixedly connected to a connecting plate. A third spring is fixedly connected to the side of the connecting plate closest to the fixed sleeve box, and the third spring is fixedly connected to the fixed sleeve box.

[0014] Preferably, the vent box has multiple vent holes on the side near the mold slide, and the fixed sleeve has multiple flow-slowing holes on the side away from the mold slide.

[0015] Preferably, the front of the drive table is provided with a coating mechanism on both sides of the clamping assembly.

[0016] Preferably, a sliding rod is fixedly connected to the outer wall of the container box, a fitting spring is fixedly connected to the end of the sliding rod away from the container box, a sleeve is fixedly connected to the end of the fitting spring away from the sliding rod, the sliding rod is movably connected inside the sleeve, a guide post corresponding to the sleeve is provided between the upper and lower clamps, the sleeve is movably connected to the outer wall of the corresponding guide post, a distance spring is fixedly connected to the top and bottom of the sleeve, a connecting frame is fixedly connected to the end of the distance spring away from the sleeve, and the connecting frame is fixedly connected to the outer wall of the corresponding clamp.

[0017] This invention provides a horizontal hydraulic press for flattening and punching both ends of a seamless tube. It has the following advantages:

[0018] 1. This horizontal hydraulic press for flattening and punching both ends of a seamless tube uses two opposite extrusion dies under automated control to flatten both ends of the seamless tube, followed by punching, to achieve integrated processing of flattening and punching at both ends of the seamless tube. This can eliminate secondary clamping errors and improve processing efficiency; at the same time, it ensures the synchronization accuracy of the extrusion pressure and feed amount at both ends, controls tube deformation, and improves processing quality.

[0019] 2. The horizontal hydraulic press for flattening and punching both ends of the seamless tube, when the seamless steel tube is extruded by the extrusion die, causes the impact plate to hit the inner side of the extrusion die, so that the seamless steel tube is affected by vibration during the extrusion process, which can make the deformation more uniform, reduce die wear and steel tube cracking, improve processing quality and processing efficiency.

[0020] 3. The horizontal hydraulic press for flattening and punching seamless steel pipes at both ends extrudes and punches the seamless steel pipes, causing the airflow at the air outlet box 72 to gradually increase in velocity. This gradually enhances the cooling effect during the extrusion process. The gradually increasing airflow can synchronously strengthen the cooling as the steel pipe is flattened and deformed, precisely preventing local overheating of the pipe. At the same time, it can reduce the internal stress of the steel pipe, making the flattened shape more regular, and also improving the structural stability of the pipe after processing, thus improving the processing quality.

[0021] 4. This horizontal hydraulic press for flattening and punching both ends of seamless pipe, when the steel pipe is not being extruded and is pushed by the extrusion component to fit the extrusion die, can cause the impact plate to impact the extrusion die, causing the die to vibrate. Combined with the airflow discharged from the air outlet, it can quickly clean the die surface, so as to avoid the metal fragments generated during the processing adhering to the die and aggravating the wear of the die during the processing, which can indirectly improve the processing quality.

[0022] 5. This horizontal hydraulic press for flattening and punching both ends of seamless steel pipe maintains contact between the rotating idler wheel and the protruding extrusion parts on both sides of the seamless steel pipe. As the steel pipe is gradually fed into the extrusion position, the rotating idler wheel applies an appropriate amount of lubricating oil to the surface of the seamless steel pipe. The flattening die will first contact the part coated with lubricating oil during the flattening process, which can make the flattened surface flat and wrinkle-free, thereby improving the processing quality.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0037] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0038] Example 1: Please refer to Figure 1-4 The present invention provides a technical solution: a horizontal hydraulic press for flattening and punching both ends of a seamless tube, including a fixed base frame 1, two extrusion components 2 are fixedly connected to the top of the fixed base frame 1, a drive platform 3 is fixedly connected to the inner side of each extrusion component 2, a control hydraulic station 4 is provided on the left side of the fixed base frame 1, the control hydraulic station 4 is connected to the two extrusion components 2 through hydraulic pipelines, a mold slide 5 is movably connected to the inner side of each drive platform 3, two extrusion molds 51 are fixedly connected to the inner side of the mold slide 5, and a punching mold platform 53 is fixedly connected to the inner side of the mold slide 5 between the two extrusion molds 51;

[0039] The control hydraulic station 4 includes an oil tank, a one-way fixed-displacement oil pump, a proportional pressure-flow composite valve, a pressure sensor (accuracy ±0.1MPa), and a PLC controller. It enables simultaneous flattening and punching (integrated processing), individual flattening, and individual punching. The pressure sensor provides real-time feedback of the extrusion pressure on both sides, and the PLC dynamically adjusts the hydraulic oil flow to ensure a pressure difference ≤2MPa. This achieves simultaneous extrusion of both sides of the seamless steel pipe.

[0040] The extrusion components 2 are symmetrically arranged on both sides of the frame, each including an extrusion cylinder, a synchronous piston rod, a left mold slider, and a right mold slider; the extrusion cylinder is a piston cylinder with a rated working pressure of 25MPa and a stroke range of 270mm.

[0041] The extrusion mold 51 is oriented in the opposite direction to the extrusion mold 51 located at its bottom. The top of the fixed base frame 1 is fixedly connected to the clamping assembly 54 on both the front and back sides of the mold slide 5. The clamping assembly 54 is fixedly connected to the drive wheel 52 on the side of the clamping assembly 54 near the mold slide 5. The clamping assembly 54 is equipped with upper and lower clamps.

[0042] The left and right drive tables 3 drive the corresponding mold slides 5 to lift the corresponding extrusion molds 51 to the same height as the extrusion components 2 on both sides. The external traction machine places the seamless tube between the corresponding extrusion molds 51, and the clamping assembly 54 clamps the tube body to achieve positioning.

[0043] Then the hydraulic system is started. The hydraulic oil flow is dynamically adjusted by the PLC in the hydraulic station 4, and the piston cylinders of the two extrusion components 2 are driven to advance synchronously. The extrusion die 51 fits the two ends of the seamless tube and applies pressure until the tube ends form a preset flat structure.

[0044] After the flattening process is completed, the piston rods of the two extrusion components 2 on both sides are retracted by controlling the hydraulic station 4. Then, the mold slide 5 is driven to move downward by the drive table 3, so that the punching mold on the punching mold table 53 is aligned with the flattened steel pipe. The piston rods of the two extrusion components 2 on both sides are pushed forward by controlling the hydraulic station 4 to perform the punching action. The punch passes through the flattening area to punch the installation hole. After the punching is completed, the punch retracts.

[0045] After the flattening and punching process of one end of the steel pipe is completed, the clamping component 54 releases its clamping and supports the steel pipe through the drive wheel 52. Then, the external traction machine drives the seamless pipe forward to the clamping component 54 on the other side, so that the end of the steel pipe that has not been squeezed is located between the mold slides 5. Then, the steel pipe is clamped and fixed by the corresponding clamping component 54. At the same time, the drive table 3 drives the mold slide 5, so that the other extrusion mold 51 is raised to the same height as the extrusion components 2 on both sides. Then, the flattening action is performed again. After the flattening action is completed, the punching action is repeated.

[0046] After punching the holes at both ends, the extruded steel pipe is removed by an external traction machine, and then an unprocessed seamless steel pipe is fed in by the external traction machine for a new round of processing.

[0047] Example 2: Please refer to Figure 1-7 Based on Embodiment 1, the present invention provides a technical solution:

[0048] A vibration mechanism 6 is fixedly connected inside the extrusion mold 51. The vibration mechanism 6 includes a guide rod 61, which is fixedly connected inside the extrusion mold 51. An impact plate 62 is movably connected to the outer wall of the guide rod 61 inside the extrusion mold 51. A first spring 63 is fixedly connected to the bottom of the impact plate 62 and is fixedly connected to the extrusion mold 51.

[0049] A pusher block 68 is movably connected to one side of the guide rod 61, and a pusher plate 64 is fixedly connected to the inside of the mold slide 5.

[0050] A second spring 65 is fixedly connected to the side of the impact plate 62 near the first spring 63. A secondary impact block 67 is fixedly connected to the end of the second spring 65 away from the impact plate 62. A limiting block 66 is fixedly connected to the side of the second spring 65 near the secondary impact block 67.

[0051] A limiting strip 610 is fixedly connected to the outer wall of the impact plate 62 on the side of the pusher block 68 near the mold slide table 5. A torsion spring 69 is fixedly connected to the outer wall of the pusher block 68 at its rotation axis, and the torsion spring 69 is fixedly connected to the corresponding impact plate 62.

[0052] The two mold slides 5 are pushed together by the extrusion component 2, so that when the extrusion mold 51 extrudes one end of the steel pipe, the push plate 64 moves to the corresponding push block 68. Through the protrusion on the push plate 64, the push block 68 is pushed downward along the inclined surface of the push block 68. The push block 68 is restricted by the limiting strip 610, thereby realizing the effect of the push plate 64 pushing the impact plate 62 through the push block 68. The impact plate 62 is pushed along the guide rod 61, and the first spring 63 is compressed. As the push plate 64 moves, the push block 68 will disengage from the push of the teeth along the inclined surface. At this time, the impact plate 62 will be elastically reset by the first spring 63 and impact the inside of the extrusion mold 51, thereby causing the extrusion mold 51 to vibrate. Vibration flattening of the steel pipe can reduce the extrusion pressure, make the deformation more uniform, reduce mold wear and steel pipe cracking, and also improve processing efficiency.

[0053] In addition, when the impact plate 62 impacts the inside of the extrusion die 51, the secondary impact block 67 will impact the limiting block 66 due to inertia and the pull of the second spring 65, which will compress the second spring 65 and generate a vibration effect. The secondary impact block 67 will be repeatedly pulled to impact the limiting block 66, and the vibration will be transmitted to the extrusion die 51 through the second spring 65 to continuously generate a weak vibration, further improving the flattening effect of the steel pipe.

[0054] After extrusion is completed, the two extrusion dies 51 gradually move away from each other under the push of the extrusion component 2. At this time, the protrusion on the push plate 64 will push the push slant block 68 in the opposite direction. The push slant block 68 will deflect and the torsion spring 69 will undergo elastic deformation. After the push plate 64 moves away from the corresponding push slant block 68, the torsion spring 69 will reset the push slant block 68 under its own elastic force.

[0055] Example 3: Please refer to Figure 1-9 Based on Embodiment 1 and Embodiment 2, the present invention provides a technical solution:

[0056] Cooling mechanisms 7 are fixedly connected to the outer side of the extrusion die 51. The cooling mechanism 7 includes a fixed sleeve 71, which is fixedly connected to the outer side of the extrusion die 51. An air inlet pipe 73 is fixedly connected to the inner side of the fixed sleeve 71, and an air inlet fan 74 is fixedly connected inside the air inlet pipe 73.

[0057] The intake fan 74 pushes external air into the intake pipe 73, which increases the air velocity inside the fixed sleeve 71, allowing airflow to be discharged from the outlet 77 and the slow flow hole 78.

[0058] An air outlet box 72 is movably connected to the inside of the fixed sleeve box 71. A connecting plate 75 is fixedly connected inside the air outlet box 72. A third spring 76 is fixedly connected to the side of the connecting plate 75 near the fixed sleeve box 71, and the third spring 76 is fixedly connected to the fixed sleeve box 71.

[0059] The vent box 72 has multiple vent holes 77 on the side near the mold slide 5, and the fixed sleeve 71 has multiple slow flow holes 78 on the side away from the mold slide 5.

[0060] During the flattening process, the airflow discharged from the vent box 72 blows towards the steel pipe between the extrusion dies 51, cooling the extruded steel pipe. As the extrusion proceeds, the two corresponding vent holes 77 come into contact with each other and begin to squeeze against each other, gradually compressing the vent holes 77 into the fixed sleeve 71. The third spring 76 is compressed. As the vent box 72 moves downward, the vent holes 77 are blocked by the fixed sleeve 71, causing the opening of the fixed sleeve 71 to gradually decrease, thereby increasing the flow rate of the airflow discharged from the vent holes 77 and gradually improving the cooling effect on the steel pipe. Subsequently, the slow flow hole 78 is blocked, further increasing the airflow rate at the vent holes 77, thus gradually improving the cooling effect during the extrusion process. The gradually increasing airflow can synchronously enhance cooling with the deformation process of the flattened steel pipe, precisely avoiding local overheating of the pipe. At the same time, the gradual cooling force can reduce the internal stress of the steel pipe, making the flattened shape more regular and improving the structural stability of the pipe after processing.

[0061] Furthermore, when the steel pipe is not being extruded and is pushed to fit by the extrusion die 51 by the extrusion component 2, the impact plate 62 can impact the extrusion die 51 to generate vibration. This vibration is further transmitted, causing the die on the die slide 5 to vibrate. As the die slide 5 gradually gets closer, the gap between the dies will decrease. The airflow discharged from the air outlet 77 on the air outlet box 72 will accelerate the airflow on the die surface. The vibration will reduce the adhesion of the deposits on the die surface, making it easier to clean the die by airflow. This will achieve the effect of conveniently cleaning the die surface, so as to avoid the debris generated by metal breakage during processing adhering to the die and aggravating the wear of the die during processing.

[0062] Example 4: Please refer to Figure 1-4 11-12, Based on Embodiment 1, the present invention provides a technical solution:

[0063] The front of the drive platform 3 is provided with coating mechanisms 55 on both sides of the clamping assembly 54. The coating mechanism 55 includes a container box 553, which is disposed between the corresponding upper and lower clamps. A rotating idler wheel 554 is movably connected inside the container box 553. A spiral rod 558 is fixedly connected to the top of the rotating idler wheel 554 inside the container box 553. The top of the container box 553 is provided with an opening, and the outer wall of the rotating idler wheel 554 is provided with a small opening. Before use, the opening on the outside of the rotating idler wheel 554 is blocked. Then, lubricating oil is added into the container box 553 through the top of the container box 553, so that the level of the lubricating oil inside the container box 553 is maintained at half the height of the container box 553. The opening is blocked with a special plug. At this time, under the action of atmospheric pressure, the lubricating oil inside the container box 553 cannot be discharged through the opening on the rotating idler wheel 554.

[0064] A sliding rod 555 is fixedly connected to the outer wall of the container box 553. A fitting spring 557 is fixedly connected to the end of the sliding rod 555 away from the container box 553. A sleeve 556 is fixedly connected to the end of the fitting spring 557 away from the sliding rod 555. The sliding rod 555 is movably connected inside the sleeve 556. A guide post corresponding to the sleeve 556 is provided between the upper and lower clamps. The sleeve 556 is movably connected to the outer wall of the corresponding guide post. A distance spring 552 is fixedly connected to both the top and bottom of the sleeve 556. A connecting frame 551 is fixedly connected to the end of the distance spring 552 away from the sleeve 556. The connecting frame 551 is fixedly connected to the outer wall of the corresponding clamp.

[0065] The fixed-distance spring 552 is a spring with a large spring constant. When the two fixed-distance springs 552 are squeezed towards the center by the corresponding connecting frame 551, the two fixed-distance springs 552 can be squeezed. Since the two fixed-distance springs 552 have a large spring constant, they can support the rotating idler wheel 554 with elastic force and position it in the middle of the two clamps.

[0066] When the external traction device feeds the seamless steel pipe between the two clamps of the clamping assembly 54, it pushes the two container boxes 553 outwards through the curved surface of the container box 553, causing the sliding rod 555 to move inwards and compressing the contact spring 557. Simultaneously, the rotating idler wheel 554, pushed by the contact spring 557, contacts the most protruding parts on both sides of the seamless steel pipe. As the external traction device continues to push the seamless steel pipe, the rotating idler wheel 554 is pushed by the steel pipe and rotates, further causing the helical winch 558 to rotate. The helical winch 558 is a spiral... The spiral structure allows the helical screw 558 to press the lubricating oil inside the container box 553 downwards. When the opening on the rotating idler wheel 554 contacts the surface of the seamless steel pipe, a small amount of lubricating oil adheres to the surface of the steel pipe, avoiding excessive lubricating oil adhesion and increasing the cost of degreasing later. After the protruding parts on both sides of the seamless steel pipe are coated with lubricating oil, the flattening mold will first contact the lubricated part during flattening. During the flattening process, the lubricating oil can be squeezed to the rest of the outer wall of the seamless steel pipe at the same time, which plays a lubricating role in flattening and makes the flattened surface flat and wrinkle-free.

[0067] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
