[0065] To facilitate the understanding of the present invention, the present application will be described more comprehensively below with reference to the relevant drawings; the drawings show preferred embodiments of the present invention, but the present invention can be implemented in many different forms and is not limited to the embodiments described herein; on the contrary, the purpose of providing these embodiments is to enable a more thorough and comprehensive understanding of the disclosed content of the present invention.

[0066] It should be noted that the terms “vertical”, “horizontal”, “up”, “down”, “left”, “right” and similar expressions used in this document are only for illustrative purposes and do not represent the only implementation method.

[0067] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which the present invention belongs; the terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more related listed items.

[0068] like Figures 1 to 17As shown, the present application proposes a vertical swing rolling machine, including a stand 100, a swing rolling device 110 and a half-axis body 300, the swing rolling device 110 includes a swing rolling head 111, the swing rolling head 111 is located below the swing rolling device 110, the swing rolling device 110 is located in the installation space of the stand 100, the swing rolling device 110 is connected to the stand 100 through an oil cylinder 120, the oil cylinder 120 is used to drive the swing rolling device 110 to rise and fall, a swing arm is fixed in the swing rolling device 110, the swing arm is used to drive the swing rolling head 111 to swing in a circle, and also includes a straightening component 200;

[0069] The straightening assembly 200 includes a swing groove 210, a steam seat 220, a polishing part 240, a support cylinder 250 and a driving part 260;

[0070] The support tube 250 is a cylindrical body with a hollow interior and openings at both ends, and is fixed to the bottom of the stand 100. The steam seat 220 is fixed on the support tube 250, and the steam seat 220 is a hollow toroidal body.

[0071] The swing groove 210 is a hollow cylinder with a large circular opening at one end and a small circular opening at the other end, and the axes of the openings at both ends coincide with each other. The swing groove 210 is located above the steam seat 220, and the bottom of the swing groove 210 contacts the steam seat 220, and the axes of the steam seat 220 and the swing groove 210 coincide with each other.

[0072] The half shaft body 300 includes a rod portion 310 and an end portion 320, and the end portion 320 is fixed to one end of the rod portion 310;

[0073] A straightening cylinder 221 is fixed to the inner side of the steam seat 220 through an annular plate. The straightening cylinder 221 is a cylinder with a hollow interior and openings at both ends. The outer diameter of the rod 310 conflicts with the inner diameter of the straightening cylinder 221. That is, the rod 310 can pass through the small round opening of the swing groove 210 and then enter the straightening cylinder 221. The end 320 contacts the concave surface of the swing groove 210. When the rod 310 completely enters the straightening cylinder 221, the bottom of the end 320 contacts the concave surface of the swing groove 210, and the end 320 supports the rod 310.

[0074] The opening of the straightening cylinder 221 coincides with the small round opening of the swing groove 210, which means that the opening diameter of the straightening cylinder 221 is equal to the small round opening diameter of the swing groove 210. A long groove 2211 is opened on the side of the straightening cylinder 221. The height of the long groove 2211 is equal to the height of the rod 310. The side of the rod 310 is exposed within the range of the long groove 2211, which is convenient for polishing the rod 310 and does not affect the straightening of the rod 310.

[0075] The steam seat 220 is connected to the water tank 270 through a pipeline, and the water in the water tank 270 is sent to the steam seat 220 through the pipeline. An air guide pipe 222 is fixed on the steam seat 220, and the free end of the air guide pipe 222 is located below the polishing part 240. The air guide pipe 222 guides the steam in the steam seat 220 to the bottom of the polishing part 240 through an air pump.

[0076] The polishing part 240 is used for polishing the outer surface of the rod 310, and the driving part 260 is used for driving the rolling groove 210 to rotate. When the rolling groove 210 rotates, it can drive the rod 310 to rotate, so that the outer surface of the rod 310 is exposed to the long groove 2211 area in turn, and steam is sprayed through the air guide pipe 222 to make the polishing part 240 move outside the straightening cylinder 221, so as to achieve polishing of the outer surface of the rod 310.

[0077] It is worth noting that a slight local bending of the rod 310 will also affect the safety of normal use of the automobile half-axle. The temperature of the end 320 can reach between 1100°C and 1150°C. The temperature of the end 320 can be transmitted to the steam seat 220, causing water to evaporate instantly after entering the steam seat 220 to generate steam.

[0078] Specifically, if Figures 7 to 11 As shown, the polishing part 240 includes an annular tube 241, which is a torus and whose axis coincides with the axis of the straightening cylinder 221;

[0079] A nozzle 2411 is fixed on the inner surface of the annular tube 241 near the long groove 2211. The nozzle 2411 is connected to the inside of the annular tube 241 and is parallel to the long groove 2211, which means that the liquid sprayed by the nozzle 2411 can contact the rod 310.

[0080] A water pipe 231 is fixed to the side of the annular tube 241. The water inlet end of the water pipe 231 extends into the water tank 270. The water tank 270 contains abrasive particles. The water in the water tank 270 is introduced into the annular tube 241 through the water pipe 231. The water flow containing abrasive particles is sprayed out through the nozzle 2411 to polish the outer surface of the rod 310.

[0081] An annular fixing plate 243 is fixed on the top of the annular tube 241 . The outer diameter of the fixing plate 243 is larger than the outer diameter of the annular tube 241 , so that the fixing plate 243 can be lifted up by steam.

[0082] It is worth noting that steam is ejected from below the fixing plate 243 , and the steam can drive the fixing plate 243 to move upward, and at the same time drive the nozzle 2411 to move in the long groove 2211 to polish the outer surface of the rod 310 .

[0083] Specifically, if Figures 9 to 15As shown, a steam cylinder 251 is fixed to the bottom of the support cylinder 250. The steam cylinder 251 is used to store steam, and the gas outlet end of the air guide pipe 222 extends into the steam cylinder 251.

[0084] A plurality of jet pipes 2511 are fixed on the steam cylinder 251 near the fixing plate 243. There are at least two jet pipes 2511 to ensure the stability of the movement of the annular tube 241. The jet pipes 2511 are located below the fixing plate 243 and are used to spray steam.

[0085] A one-way valve is fixed on each of the jet pipes 2511, and the one-way valve is used to prevent external air from entering the steam cylinder 251. One jet pipe 2511 is fixed to the side of the annular pipe 241 through a fixing frame 2512. The jet pipe 2511 consists of two branch pipes and a bellows. The bellows is fixed between the two branch pipes. The fixing frame 2512 is fixed to a straight pipe, and the one-way valve is fixed to another straight pipe close to the steam cylinder 251. That is to say, the bellows is stretched during the rising process of the annular pipe 241, which can drive the jet pipe 2511 to move up synchronously, so that the fixing plate 243 and the jet pipe 2511 are kept at a close distance, thereby reducing the waste of steam.

[0086] It is worth noting that the steam generated in the steam seat 220 is sent into the steam cylinder 251 through the air guide pipe 222. When in use, the one-way valve on the jet pipe 2511 is directly opened to allow the steam to eject and lift the fixed plate 243 and drive the annular tube 241 to move.

[0087] Specifically, if Figure 6 As shown, a plurality of through holes are opened on the steam seat 220 near the swing groove 210, and a metal rod 224 is fixed in one of the through holes. The metal rod 224 is preferably made of copper, but can also be made of other metal materials with good thermal conductivity. One end of the metal rod 224 is in contact with the swing groove 210, and the other end of the metal rod 224 extends into the steam seat 220. The liquid entering the metal rod 224 is in contact with one end of the steam seat 220, and the connection between the metal rod 224 and the through hole is airtight and fixed, so that the steam will not be discharged outward.

[0088] It is easy to understand that the metal rod 224 can transfer the heat of the inner end 320 of the swing groove 210 to the steam seat 220 more quickly, thereby reducing the energy loss during the heat transfer process and further enhancing the utilization value of the workpiece itself.

[0089] Specifically, if Figures 3 to 9 As shown, a second clamping cylinder 211 is fixed in the swing groove 210, and the second clamping cylinder 211 is used to clamp the end 320 after swinging;

[0090] The driving part 260 includes a motor, a gear 1 261 and a gear 2 262. The gear 2 262 is sleeved and fixed on the outside of the swing rolling groove 210. The gear modules of the gear 2 262 and the gear 1 261 are equal. The motor is used to drive the gear 1 261 to rotate. As the gear 1 261 rotates, the gear 2 262 and the swing rolling groove 210 are driven to rotate.

[0091] In the above embodiment, one end of the rod 310 is placed in the small round opening of the swing groove 210. The staff can clamp the end 320 with tools such as pliers, drive the swing device 110 downward through the oil cylinder 120, and use the swing head 111 to press the end 320 downward, so that the rod 310 moves in the straightening cylinder 221. After the bent part of the rod 310 enters the straightening cylinder 221, the rod 310 is straightened by the straightening cylinder 221 until the end 320 contacts the inner concave surface of the swing groove 210, and then the end 320 is processed by the swing head 111. The oil cylinder 120 drives the swing device 110 to feed downward, so that the swing head 111 and the end 320 generate a small area of ​​local contact pressure zone, so that the pressurized end 320 continuously produces plastic overall deformation, and finally a disc-shaped end 320 is obtained;

[0092] Afterwards, the end portion 320 is clamped by the clamping cylinder 211, and the end portion 320 is driven to rotate by the driving unit 260, so that the rod portion 310 rotates synchronously, and at the same time, the one-way valve on the jet pipe 2511 is opened, steam is ejected from the jet pipe 2511 and drives the annular pipe 241 to move upward, and the liquid containing abrasive particles is ejected through the nozzle 2411 to polish the outer surface of the rod portion 310. After the annular pipe 241 moves to the top, the one-way valve of the jet pipe 2511 is closed, and the steam ejection is stopped. The annular pipe 241 moves downward by its own weight, and the polishing operation of the rod portion 310 is still maintained during the downward movement. After the nozzle 2411 moves down to the bottom of the rod portion 310, the one-way valve of the nozzle 2411 is opened again, and the cycle operation is continued until the polishing of the rod portion 310 is completed, so that the rod portion 310 can be straightened during the feeding process, and at the same time, the high temperature of the end portion 320 is used to evaporate the liquid to generate water vapor to drive the polishing unit 240 to complete the surface polishing of the rod portion 310, thereby improving the processing efficiency.

[0093] In some embodiments of the present application, Figures 4 to 17 As shown, a hot water seat 230 is fixed on the support cylinder 250 away from the swing groove 210;

[0094] The hot water seat 230 is a hollow cylinder, and is located below the steam seat 220. The hot water seat 230 and the steam seat 220 are fixed, and the water inlet end of the water pipe 231 extends into the hot water seat 230. The water pipe 231 is connected to a water pump, and the liquid heated by the hot water seat 230 is sent into the annular pipe 241 through the water pump.

[0095] A water pipe 271 is fixed on the water tank 270, and the water pipe 271 is connected to the water pump. The water pipe 271 has two water outlets, one of which extends into the steam seat 220, and the other extends into the hot water seat 230. That is to say, after the liquid containing abrasive particles enters the hot water seat 230, it can heat the liquid, thereby further improving the polishing effect.

[0096] It is worth noting that the hot water seat 230 and the steam seat 220 are both made of metal heat-conducting materials. The heat conducted in the hot water seat 230 is less than the heat conducted in the steam seat 220. The heat of the end 320 can heat the liquid in the hot water seat 230, making the polishing efficiency higher.

[0097] Specifically, if Figures 9 to 16 As shown, the inner diameters of the hot water seat 230 and the steam seat 220 are equal, and the outer diameter of the fixing plate 243 is not larger than the inner diameter of the hot water seat 230 , that is, the space within the hot water seat 230 and the steam seat 220 can accommodate the fixing plate 243 without affecting the movement of the fixing plate 243 .

[0098] In the above embodiment, the water pipe 271 delivers the water in the water tank 270 to the hot water seat 230 and the steam seat 220 through a water pump. After the liquid enters the hot water seat 230, the temperature of the end 320 heats the liquid, and the heated liquid is delivered to the annular tube 241 through the water pipe 231, so that the nozzle 2411 sprays out the heated liquid, which can separate the impurities at the rod 310 more quickly, improve the polishing efficiency at the rod 310, and thus improve the processing efficiency.

[0099] Specifically, if Figure 3 As shown, a grinding cylinder 223 is fixed inside the straightening cylinder 221. The grinding cylinder 223 is a cylinder with a hollow interior and openings at both ends and grooves on the side. The notch of the grinding cylinder 223 coincides with the long groove 2211 of the straightening cylinder 221. That is, the grinding cylinder 223 does not affect the polishing process of the rod 310.

[0100] The inner wall of the grinding cylinder 223 contacts the outer surface of the rod 310 .

[0101] In the above embodiment, after the rod 310 enters the straightening cylinder 221, it contacts the grinding cylinder 223. The grinding cylinder 223 can not only straighten the rod 310, but also increase the contact force with the outer surface of the rod 310, so that the straightening effect is better. At the same time, the burrs and oxide scales on the outer surface of the rod 310 can be scraped off. As the rod 310 rotates in the grinding cylinder 223, the outer surface of the rod 310 can be polished, and at the same time, the nozzle 2411 is cooperated to spray polishing, thereby reducing the burden of polishing operation and improving polishing efficiency.

[0102] In some embodiments of the present application, Figure 10 to Figure 11As shown, a telescopic tube 242 is fixed at the bottom of the annular tube 241. The inner diameter of the telescopic tube 242 is larger than the inner diameter of the annular tube 241, and the axis of the telescopic tube 242 coincides with the axis of the annular tube 241. The telescopic tube 242 can follow the movement of the annular tube 241 and telescope. The telescopic tube 242 is used to prevent the liquid generated by polishing from splashing everywhere. An arc-shaped baffle 244 is fixed on the end of the fixed plate 243 away from the telescopic tube 242. The baffle 244 is used to further reduce the splash of liquid during polishing.

[0103] A water collecting cylinder 252 is fixed at the bottom of the support cylinder 250 near the steam cylinder 251;

[0104] The water collecting cylinder 252 is a cylinder with a hollow interior and an open end close to the steam cylinder 251, and an annular plate is fixed to the open end of the water collecting cylinder 252, and the annular plate extends into the telescopic tube 242, that is, the liquid produced by polishing falls into the water collecting cylinder 252, and the abrasive particles produced by polishing the rod 310 can be recycled;

[0105] A return pipe 2521 is fixed on the water collecting cylinder 252, and a water pump is fixed on the return pipe 2521. The liquid is sent into the water tank 270 again through the water pump, and the water outlet end of the return pipe 2521 extends into the water tank 270. That is to say, in the initial state, a small amount of abrasive particles only needs to be added to the water tank 270, and the grinding chips generated by grinding enter the water tank 270 along with the liquid, thereby saving the use cost.

[0106] It should be noted that the recycled liquid does not affect the evaporation of the liquid in the steam seat 220, and the particles contained in the evaporated water vapor can increase the contact strength between the steam and the fixed plate 243, thereby improving the polishing efficiency.

[0107] In the above embodiment, during the movement of the annular tube 241, the sprayed liquid is intercepted by the telescopic tube 242, so that the sprayed liquid falls into the water collecting tube 252. At the same time, the grinding chips generated by grinding enter the water collecting tube 252 along with the liquid, and are then drawn into the water tank 270 through the return pipe 2521, so as to facilitate the recycling of the grinding chips, reduce resource waste, and save usage costs.

[0108] In some embodiments of the present application, Figures 1 to 5 As shown, a guide portion 130 is positioned on the stand 100, and the guide portion 130 is used to guide the rod 310 so that the rod 310 remains in a vertical state and enters the straightening cylinder 221;

[0109] The guide portion 130 includes a guide ring 131, the guide ring 131 is parallel to the straightening cylinder 221, and the axes of the guide ring 131 and the straightening cylinder 221 coincide with each other;

[0110] The guide ring 131 is a circular ring and two parallel moving plates 133 are fixed on its side, and a slider is fixed on the free end of each moving plate 133;

[0111] The stand 100 is provided with a slide groove near the movable plate 133, and the slider extends into the slide groove. The contact force between the slider and the slide groove is large, which has a supporting and guiding effect on the rod 310, and a rectangular groove is respectively provided at the top and the bottom of the slide groove. The rectangular groove at the top of the slide groove is convenient for placing the movable plate 133, and the rectangular groove at the bottom of the slide groove is convenient for taking out the movable plate 133.

[0112] A plurality of clamping cylinders 132 are fixed in the guide ring 131 , and the clamping cylinders 132 are used for clamping the end portion 320 .

[0113] In the above embodiment, the rod 310 is placed in the guide ring 131, and the end portion 320 is supported by the clamping cylinder 132. As the swinging device 110 moves downward, the rod 310 is pressed into the straightening cylinder 221. When the end portion 320 enters the swinging groove 210, the oil cylinder 120 drives the swinging device 110 to move up a certain distance. At the same time, the clamping cylinder 132 releases the clamping of the end portion 320, adjusts the position of the movable plate 133, and removes the movable plate 133 from the rectangular groove at the bottom of the slide groove. After the end portion 320 is swung and rolled, the swinging device 110 moves up and resets, and then the movable plate 133 is pushed into the slide groove from the rectangular groove at the top of the slide groove, thereby enhancing the supporting and guiding effect on the rod 310, thereby improving the straightening effect of the rod 310 and reducing the workload.

[0114] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
