[0036] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0037] A sliding sleeve shank forging device based on local upsetting according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0038] like Figures 1 to 13 As shown, an embodiment of the present invention provides a sliding sleeve handle forging device based on local upsetting, a working frame 8 and a sliding sleeve body 12, an arc-shaped fixed seat 23 is provided inside the working frame 8, an arc-shaped fixed seat 23 is provided inside an arc-shaped bearing plate 24, the sliding sleeve body 12 is arranged inside the arc-shaped bearing plate 24, a positive magnetic block 25 is provided on the top of the arc-shaped fixed seat 23, and a matching negative magnetic block 26 is provided on the bottom of the arc-shaped bearing plate 24, the positive magnetic block 25 and the negative magnetic block 26 are attracted to each other, so that the arc-shaped fixed seat 23 is fixedly connected with the arc-shaped bearing plate 24, a fixing sleeve 16 is provided at one end of the sliding sleeve body 12, and a sliding sleeve handle end 13 is provided at one end of the sliding sleeve body 12; an electric retractor opening module 27 and a forging machine opening module 28 are also provided on the top of the arc-shaped fixed seat 23, the electric retractor opening module 27 is electrically controlled and connected to the electric retractor 14 through a conductive line, and the forging machine opening module 28 is electrically controlled and connected to the forging machine 37 through a conductive line.

[0039] In a specific application of the embodiment of the present invention, the sleeve body 12 is placed inside the arc-shaped bearing plate 24, and one end of the sleeve body 12 is placed inside the fixed sleeve 16. The sleeve body 12 uses its own weight to apply pressure to the arc-shaped bearing plate 24, and the arc-shaped bearing plate 24 descends toward the inside of the arc-shaped fixed seat 23. The distance between the positive magnetic block 25 and the negative magnetic block 26 gradually decreases until the two are close to each other. Due to the magnetic effect, a magnetic connection is formed between the arc-shaped fixed seat 23 and the arc-shaped bearing plate 24. The magnetic locking ensures that the sleeve body can maintain a stable position during the subsequent forging process to prevent any possible deviation; when the arc-shaped fixed seat 23 and the arc-shaped bearing plate 24 contact each other, they will touch the electric retractor opening module 27 and the forging machine opening module 28, and then the electric retractor 14 and the forging machine 37 start working, and move the sleeve handle end 13 toward the forging machine 37 (see Appendix). Fig.13 The middle dotted line is the moving track of the sleeve body 12), and the forging machine 37 applies huge pressure to shape the end 13 of the sleeve shank to complete the local upsetting process.

[0040] In a possible embodiment, a forger 37 is provided with a heating block 38 at the working end of the forger 37. The shapes of the forger 37 and the heating block 38 change according to the shape of the sleeve body 12. One end of the sleeve handle end 13 is close to the forger 37. A fixed support rod 39 is provided on the outer wall of the forger 37. The other end of the fixed support rod 39 is arranged inside the working frame 8.

[0041] In a specific application of the embodiment of the present invention, the forger 37 and the heating block 38 are working, and the sleeve shank end 13 will be placed in the heating block 38 for preheating until it reaches a set high temperature state. When the sleeve shank reaches a suitable temperature, the forger will implement a rapid and powerful impact or pressure action on the shank end, causing it to undergo plastic flow under the action of high temperature and high pressure. The shape and size of the sleeve shank end 13 gradually change with the continuous action of the forger 37, thereby completing the forging work. The forger 37 and the heating block 38 used in this device will be changed according to different production requirements. At the same time, the sleeve body 12 and the sleeve shank end 13 in the accompanying drawings are all schematic shapes, and related components will be changed according to their shapes during production.

[0042] In a possible embodiment, an electric retractor 14 is provided at the bottom of the working frame 8, and an L-shaped driving rod 15 is provided at the working end of the electric retractor 14, and the other end of the L-shaped driving rod 15 is provided on the outside of the fixed sleeve 16; two groups of mounting grooves 17 are opened on the outer wall of the fixed sleeve 16, and touch blocks 18 are provided inside the two groups of mounting grooves 17, and a second damping buffer rod 19 is provided on one side of the touch block 18; two groups of fixing grooves 20 are provided on the outside of the working frame 8, and an electric retractor closing module 21 and a forging machine closing module 22 are respectively provided inside the two groups of fixing grooves 20, and the positions of the electric retractor closing module 21 and the forging machine closing module 22 respectively correspond to the positions of the two groups of touch blocks 18, and the electric retractor closing module 21 is electrically controlled and connected to the electric retractor 14 through a conductive line, and the forging machine closing module 22 is electrically controlled and connected to the forging machine 37 through a conductive line.

[0043] In a specific application of the embodiment of the present invention, the electric retractor 14 works, driving the fixed sleeve 16 and the sliding sleeve body 12 to advance into the interior of the working frame 8. At this time, the sliding sleeve handle end 13 is being upset, and then the two groups of touch blocks 18 move along a predetermined trajectory to the interior of the fixed groove 20 respectively, thereby contacting the electric retractor closing module 21 and the forging machine closing module 22. After the contact, the sliding sleeve handle end 13 also completes the forging work, and then the electric retractor 14 and the forging machine 37 will automatically stop working, the sliding sleeve body 12 will no longer advance into the interior of the working frame 8, and the forging machine 37 will no longer apply pressure to the sliding sleeve handle end 13, thereby completing the automatic forging work.

[0044] In a possible implementation, a guide plate 29 is provided inside the working frame 8, an impurity guide groove 30 is opened inside the guide plate 29, and two groups of grooves 31 are opened on the outside of the working frame 8, and the sizes of the two groups of grooves 31 are adapted to the sizes of the impurity guide groove 30.

[0045] In a specific application of the embodiment of the present invention, when the end 13 of the sliding sleeve handle is being forged, the guide plate 29 is located below the end 13 of the sliding sleeve handle. When the molten metal drips, it will first be intercepted by the guide plate 29. The molten metal will then be discharged to the outside of the working frame 8 through the groove 31 through the impurity guide groove 30 on the guide plate 29, thereby effectively preventing the molten metal from splashing everywhere and providing a safe working environment for subsequent forging work.

[0046] In a possible embodiment, the gas guide assembly 1 includes a filter plate 2, a threaded sleeve 4, a threaded rod 6 and a guide blade 7. The filter plate 2 is provided with two groups, the threaded rod 6 is provided between the two groups of filter plates 2, the threaded sleeve 4 is provided on the outer wall of the threaded rod 6, the guide blade 7 is provided on the outer side of the threaded sleeve 4, and the first damping buffer rod 5 is provided on both sides of the threaded sleeve 4, and bearing seats 3 are provided at both ends of the threaded rod 6. The two groups of bearing seats 3 are respectively provided on one side of the two groups of filter plates 2; the outer wall of the working frame 8 is provided with a gas exchanger 32, one end of the gas exchanger 32 is provided with an L-shaped delivery pipe 33, the other end of the L-shaped delivery pipe 33 is provided on the outer side of the sliding sleeve body 12, and the other end of the gas exchanger 32 is provided with a ventilation pipe 34, the gas guide assembly 1 is provided inside the ventilation pipe 34, and the other end of the ventilation pipe 34 is provided with a gas delivery plate 35, and the surface of the gas delivery plate 35 is provided with ventilation holes 36.

[0047] In a specific application of the embodiment of the present invention, when the forging work starts, the temperature of the end 13 of the sleeve shank increases due to friction and is much higher than the temperature behind the sleeve body 12. The gas exchanger 32 draws gas with a lower temperature from around the sleeve body 12 into the interior through the L-shaped delivery pipe 33 to achieve gas temperature regulation.

[0048] The two ends of the gas exchanger 32 are respectively connected to an L-shaped delivery pipe 33 and a ventilation pipe 34. The gas exchanger 32 is started through the control panel 11 (during forging, the temperature of the end 13 of the sliding sleeve handle will be significantly higher than the temperature behind the sliding sleeve body 12, resulting in a large temperature difference, which is easy to damage the sliding sleeve body 12). When the gas exchanger 32 works, the gas (with a lower temperature) around the outside of the sliding sleeve body 12 is first pumped into the inside of the gas exchanger 32 through the L-shaped delivery pipe 33, and then the gas is transported to the end 13 of the sliding sleeve handle through the ventilation pipe 34 by using the working principle of the gas exchanger 32 itself to control the temperature (see Appendix). Fig.13The solid line in the middle is the gas pumping path). During the gas transportation inside the ventilation pipe 34, the threaded sleeve 4 will move on the outside of the threaded rod 6, and the guide vane 7 will rotate on the outer wall of the threaded sleeve 4 to adjust the gas pressure to avoid damage to the components caused by excessive gas pressure. Subsequently, the gas will be released through the gas delivery plate 35 and the air vent 36 to the junction of the forger 37 and the end of the sleeve handle 13 to complete the gas regulation work, so as to balance the temperature, reduce the temperature difference, and avoid overheating damage to the sleeve body 12.

[0049] In a possible implementation manner, a control panel 11 is disposed on the outer wall of the working frame 8 , and the control panel 11 is electrically controlled and connected to the gas exchanger 32 and the heating block 38 through conductive wires.

[0050] In a specific application of the embodiment of the present invention, the gas exchanger 32 and the heating block 38 used in the device are both mature existing technologies, and the working principles of the gas exchanger 32 and the heating block 38 are also well known to those skilled in the art, and will not be described in detail here.

[0051] In a possible implementation, support columns 9 are respectively provided at the four corners of the bottom surface of the working frame 8 , and the bottom surfaces of the four support columns 9 are each provided with a wear-resistant plate 10 , and the bottom surfaces of the wear-resistant plates 10 are provided with anti-slip grooves.

[0052] In a specific application of the embodiment of the present invention, the bottom surfaces of the four support columns 9 are all provided with wear-resistant plates 10, which are usually made of alloy materials with high hardness and high wear resistance, and can effectively resist wear and corrosion in long-term use, thereby extending the service life of the equipment. The bottom surface of the wear-resistant plate 10 is provided with anti-slip grooves to increase the friction when in contact with the ground, prevent instability caused by sliding during operation, and further improve the safety performance of the device.

[0053] When the present invention is used in practice, the sleeve body 12 is placed inside the arc-shaped bearing plate 24, and one end of the sleeve body 12 is placed inside the fixed sleeve 16. The sleeve body 12 uses its own weight to apply pressure to the arc-shaped bearing plate 24, and the arc-shaped bearing plate 24 descends toward the inside of the arc-shaped fixed seat 23 until the positive magnetic block 25 and the negative magnetic block 26 are close to each other. The arc-shaped fixed seat 23 and the arc-shaped bearing plate 24 are fixedly connected by magnetism. When the arc-shaped fixed seat 23 and the arc-shaped bearing plate 24 contact each other, they will touch the electric retractor opening module 27 and the forging machine opening module 28, and then the electric retractor 14 and the forging machine 37 will start working, and the sleeve handle end 13 will be moved toward the forging machine 37 to start the forging work of the sleeve handle end 13.

[0054] Specifically, the forger 37 and the heating block 38 work to forge the end 13 of the sliding sleeve shank so that it gradually deforms under high temperature and high pressure.

[0055] Specifically, the electric retractor 14 works, driving the fixed sleeve 16 and the sliding sleeve body 12 to advance into the interior of the working frame 8. At this time, the sliding sleeve handle end 13 is being forged. Subsequently, the two groups of touch blocks 18 respectively enter the interior of the fixed groove 20, thereby contacting the electric retractor closing module 21 and the forging device closing module 22. After the contact, the sliding sleeve handle end 13 also completes the forging work. Then the electric retractor 14 and the forging device 37 will automatically stop working, the sliding sleeve body 12 will no longer advance into the interior of the working frame 8, and the forging device 37 will no longer apply pressure to the sliding sleeve handle end 13, thereby completing the automatic forging work.

[0056] Specifically, during the forging process of the sleeve handle end 13 , molten metal will drip onto the guide plate 29 , and the molten metal will be discharged to the outside of the working frame 8 through the groove 31 via the impurity guide groove 30 on the guide plate 29 .

[0057] Specifically, the two ends of the gas exchanger 32 are respectively connected with an L-shaped delivery pipe 33 and a ventilation pipe 34. The gas exchanger 32 is started through the control panel 11. First, the gas around the outside of the sleeve body 12 is pumped to the inside of the gas exchanger 32 through the L-shaped delivery pipe 33. Then, the working principle of the gas exchanger 32 itself is used to deliver the gas to the end 13 of the sleeve handle through the ventilation pipe 34. During the gas transportation inside the ventilation pipe 34, the threaded sleeve 4 will move on the outside of the threaded rod 6. At the same time, the guide vane 7 rotates on the outer wall of the threaded sleeve 4 to adjust the gas pressure. Then, the gas is released to the junction of the forger 37 and the sleeve handle end 13 through the gas delivery plate 35 and the air vent 36 to complete the gas regulation work.
