Description

Technical Field

[0001] The invention relates to a spin forming device, to the technical field of spin forming production, and in particular to a spin forming device and a spin forming method thereof. Background Art

[0002] When metal materials are spun, a large amount of heat energy is generated at the contact point with the spinning wheel. If the excess heat cannot be discharged in time, the rapidly rising temperature will affect the quality of the workpiece and is not conducive to the continuous use of the equipment.

[0003] Existing spin forming equipment helps to cool down by spraying cooling oil. However, on the one hand, the directly sprayed cooling oil has a short contact time with the metal surface under the action of gravity, and when the cooling oil contacts the metal surface, steam isolation will be generated, affecting the heat energy conduction, resulting in poor cooling effect. On the other hand, in order to avoid the metal material heating up too fast and the cooling oil splashing, it is necessary to maintain a low equipment speed. In order to avoid affecting product quality, the spinning production speed can only be reduced.

[0004] To this end, those skilled in the art have proposed a spin forming device and a spin forming method thereof, and have made structural improvements to the existing spin forming device, which can help the device to dissipate heat quickly. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides a spin forming device and a spin forming method thereof, which adopts a cooling oil tank instead of the jet cooling of the prior art, thereby increasing the contact time and contact area between the metal workpiece and the cooling oil. In addition, a splash-proof tooling is arranged against the surface of the metal workpiece, which moves synchronously with the spinning wheel frame to avoid oil splashing.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a spin forming device, including a main shaft and a rotating wheel frame, the main shaft is used to position and rotate the blank, different metal blanks correspond to different tooling installed on the end of the main shaft, and the rotating wheel frame pulls the rotating wheel to advance the blank for extrusion, thereby realizing the spinning forming of the blank.

[0007] However, since a large amount of heat energy is generated when metal materials are extruded and deformed, it will affect product quality if it is not discharged in time. The existing technology uses a method of spraying cooling oil on the surface of the metal blank to help cool it down, but the cooling effect is not very good, resulting in low production efficiency of existing spinning equipment. In view of this, technical personnel in this field have proposed cooling improvements to the equipment.

[0008] A lifting rod is arranged below the main shaft, and a cooling oil tank is fixed on the top of the lifting rod. The height of the cooling oil tank is controlled by the lifting rod so that the bottom of the metal workpiece is submerged in the cooling oil, thereby increasing the contact area between the cooling oil and the metal workpiece and helping the workpiece to cool down quickly.

[0009] A carry platform is symmetrically arranged on one side of the main shaft. The carry platform advances synchronously with the spinning wheel frame. A splash-proof tooling is arranged on the side of the carry platform. As the spinning wheel frame rotates, the splash-proof tooling fixed on the carry platform rotates while tightly contacting the surface of the metal workpiece, blocking the cooling oil splashed by the metal workpiece to prevent splashing.

[0010] Preferably, a guide rail is fixed below the main shaft along the direction of the main shaft. An installation plate is slidably arranged inside the guide rail. The lifting rod is fixedly arranged on the upper surface of the installation plate. For different specifications of spinning tooling, it is necessary to adjust the installation position of the installation plate on the guide rail according to the processing requirements, and correspondingly control the lifting height of the lifting rod to position the installation position of the installation plate and set the height of the lifting rod.

[0011] Preferably, a transmission wheel is arranged between the spinning wheel frame and the carry platform. Through the transmission wheel and the carry rod, it is ensured that the carry platform changes its position correspondingly with the advancement of the spinning wheel frame, ensuring that it always tightly contacts the surface of the metal workpiece.

[0012] A positioning screw is fixed on the side of the carry platform. The splash-proof tooling is fixedly arranged on the side of the carry platform through the positioning screw. Different toolings are selected in the spinning production of different workpieces and installed through the positioning screw.

[0013] Preferably, a carry groove is opened on the side of the splash-proof tooling. A pressing roller is slidably arranged inside the carry groove. The pressing roller is slidably installed in the carry groove, ensuring the pressing of the pressing roller on the surface of the metal workpiece and avoiding overly severe frictional contact between the pressing roller and the surface of the metal workpiece.

[0014] The splash-proof tooling blocks the cooling oil by tightly contacting the surface of the metal material through the pressing roller. The pressing roller moving synchronously with the spinning wheel frame can avoid hindering the metal workpiece.

[0015] Preferably, a slider is slidably arranged inside the carry groove. The pressing roller is installed through the slider, and the slider slides and presses tightly inside the carry groove.

[0016] A first spring is fixedly connected to the side of the slider. The slider is pressed tightly against the inside of the carry groove through the first spring. When the pressing roller tightly contacts the surface of the metal workpiece and is squeezed by the metal workpiece, the first spring deforms to buffer the squeezing effect, avoiding excessive friction loss between the pressing roller and the metal workpiece.

[0017] Preferably, an installation shaft is fixedly connected to the side of the slider. The pressing roller is sleeved on the side of the installation shaft through a bearing.

[0018] An installation sleeve is fixed to the side of the splash-proof tooling. One end of the first spring away from the slider extends into the inner side of the installation sleeve, and the installation sleeve can prevent the first spring that has been squeezed and deformed from undergoing uncontrolled deformation.

[0019] Preferably, a baffle is inserted on the side of the carry platform. A second spring is tightly arranged between the baffle and the carry platform. The baffle is tightly arranged on one side of the splash-proof tooling through the second spring. As the slider slides in the carry groove, the baffle changes its position accordingly, ensuring that the baffle always blocks the pressing roller.

[0020] Preferably, a convex block is fixedly connected to the side of the baffle. One end of the second spring is fixedly connected to the side of the convex block, and the second spring presses against the baffle through the convex block.

[0021] One end of the baffle close to the installation shaft is fixedly connected with a pressing sleeve, and the pressing sleeve presses against the installation shaft to ensure the relative position between the baffle and the pressing roller.

[0022] Preferably, a lead screw is fixedly connected to the side of the carry platform corresponding to the second spring, and the installation of the second spring can be positioned through the lead screw.

[0023] A tightening nut is threadedly sleeved on the side of the lead screw, and the magnitude of the elastic force exerted by the second spring on the baffle is controlled by the position of the tightening nut on the side of the lead screw.

[0024] A forming method for a spinning forming device:

[0025] S1. After installing the spinning tooling at the end of the main shaft, adjust the installation position of the cooling oil tank and the lifting height of the lifting rod according to the tooling, so that the cooling oil tank can submerge the metal workpiece to a certain height for cooling after rising;

[0026] Check the oil in the cooling oil tank to ensure the cooling effect of the cooling oil, and then match the splash-proof tooling accordingly. Different splash-proof toolings ensure tight contact with the surface of the metal workpiece, thereby preventing the cooling oil from being splashed by the rotating metal workpiece.

[0027] S2. Install the metal blank at the end of the main shaft, and start running the spinning wheel frame to spin-process the metal blank. The carry platform advances synchronously with the spinning wheel frame to ensure tight contact between the splash-proof tooling and the side of the metal blank. The reversely rotating metal workpiece and the splash-proof tooling can strip the cooling oil splashed by inertia from the surface of the metal workpiece.

[0028] S3. The main shaft drives the metal blank to rotate, the spinning wheel presses against the surface of the metal blank to apply pressure, and the splash-proof tooling presses against the metal blank at a height close to the liquid level of the cooling oil tank, presses against the surface of the metal blank and rotates to peel off the cooling oil liquid lifted by the surface of the metal blank.

[0029] The present invention discloses a spinning forming device and a spinning forming method thereof, and the beneficial effects thereof are as follows:

[0030] 1. For the spinning forming device and the spinning forming method thereof, a liftable cooling oil tank is arranged below the main shaft to submerge the spinning workpiece to help with cooling, increasing the contact between the workpiece and the cooling oil liquid, avoiding factors such as short contact time and gas isolation on the contact surface in oil spraying cooling that affect the cooling effect. In addition, in order to avoid the problem of cooling oil liquid splashing caused by the rotation of the workpiece, a carry platform and splash-proof tooling are also associated with the carry setting of the spinning wheel frame. The attached oil liquid is peeled off by the pressing rollers in contact with the surface of the workpiece, ensuring the rotation speed of the device, thereby improving the processing efficiency of the device.

[0031] 2. For the spinning forming device and the spinning forming method thereof, the liftable lift oil tank is used to replace the oil spraying cooling in the prior art. On the one hand, the contact time between the cooling oil liquid in oil spraying cooling and the surface of the workpiece is short, and it is easy to generate gas isolation on the contact surface between the metal workpiece and the oil liquid, affecting heat conduction. On the other hand, the contact area between the spinning workpiece and the cooling oil liquid is increased, thereby better ensuring the cooling effect.

[0032] 3. For the spinning forming device and the spinning forming method thereof, a carry platform is symmetrically arranged on one side of the main shaft and associated with the spinning wheel frame. As the spinning wheel frame advances, the carry platform and the splash-proof tooling on the side of the carry platform are driven to advance, ensuring the pressing contact between the splash-proof tooling and the surface of the spinning workpiece. The cooling oil liquid lifted by the rotating workpiece is peeled off by the pressing rollers to avoid splashing.

[0033] 4. For the spinning forming device and the spinning forming method thereof, the side of the splash-proof tooling is provided with pressing rollers by pressing against the surface of the workpiece through a first spring. The pressing rollers are in rolling contact with the surface of the workpiece, and the workpiece presses against the pressing rollers for buffering through the deformation of the first spring. On the one hand, the resistance of rolling friction is smaller than that of sliding friction, ensuring the peeling effect of the cooling oil liquid while reducing the friction loss of the splash-proof tooling. On the other hand, the wear of the splash-proof tooling is buffered through the deformation of the first spring, ensuring the pressing state between the two. Description of the Drawings

Specific embodiments

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0044] The embodiments of the present invention disclose a spinning forming device;

[0045] According to the attached Figure 1 As shown, it includes a main shaft 1 and a spinning wheel frame 2. The main shaft 1 positions and rotates the blank. Different metal blanks are installed at the end of the main shaft 1 corresponding to different toolings. The spinning wheel frame 2 pulls the spinning wheel to carry the blank for extrusion to achieve the spinning forming of the blank.

[0046] However, since a large amount of heat energy is generated when metal materials are extruded and deformed, it will affect product quality if it is not discharged in time. The existing technology uses a method of spraying cooling oil on the surface of the metal blank to help cool it down, but the cooling effect is not very good, resulting in low production efficiency of existing spinning equipment. In view of this, technical personnel in this field have proposed cooling improvements to the equipment.

[0047] A lifting rod 3 is provided below the spindle 1, and a cooling oil tank 4 is fixed on the top of the lifting rod 3. The height of the cooling oil tank 4 is controlled by the lifting rod 3 so that the bottom of the metal workpiece is submerged in the cooling oil, thereby increasing the contact area between the cooling oil and the metal workpiece and helping the workpiece to cool down quickly.

[0048] A carry-in platform 5 is provided on one side of the main shaft 1 and the rotating wheel frame 2 is symmetrically arranged. The carry-in platform 5 and the rotating wheel frame 2 are synchronously arranged. A splash-proof tooling 6 is provided on the side of the carry-in platform 5. With the rotation of the rotating wheel frame 2, the splash-proof tooling 6 fixed on the carry-in platform 5 contacts the surface of the metal workpiece and rotates, thereby blocking the cooling oil brought up by the metal workpiece and preventing splashing.

[0049] According to the attached Figure 2 and attached Figure 3 As shown, a guide rail 7 is fixed below the spindle 1 and along the direction of the spindle 1, a mounting plate 8 is slidably provided on the inner side of the guide rail 7, and the lifting rod 3 is fixedly provided on the upper surface of the mounting plate 8. For spinning tooling of different specifications, it is necessary to adjust the installation position of the mounting plate 8 on the guide rail 7 according to processing needs, and control the lifting height of the lifting rod 3 accordingly, locate the installation position of the mounting plate 8 and set the height of the lifting rod 3.

[0050] A transmission wheel 9 is arranged between the rotating wheel frame 2 and the advancing platform 5. The transmission wheel 9 and the advancing rod ensure that the advancing platform 5 changes position accordingly with the advancement of the rotating wheel frame 2, ensuring that it always presses against the surface of the metal workpiece.

[0051] A positioning screw 10 is fixed to the side of the carrying platform 5 , and the splash-proof tooling 6 is fixedly arranged on the side of the carrying platform 5 through the positioning screw 10 . Different tooling is selected in the spinning production of different workpieces and installed through the positioning screw 10 .

[0052] According to the attached Figure 4 and attached Figure 5 As shown, a side of the splash-proof tooling 6 is provided with an entry groove 11, and a clamping roller 12 is slidably arranged on the inner side of the entry groove 11. The clamping roller 12 is slidably installed in the entry groove 11 to ensure that the clamping roller 12 is pressed against the surface of the metal workpiece, while avoiding excessive frictional contact between the clamping roller 12 and the surface of the metal workpiece.

[0053] The splash-proof tooling 6 blocks the cooling oil by pressing the pressing roller 12 against the surface of the metal material. The pressing roller 12 that moves synchronously with the rotating wheel frame 2 can avoid obstruction to the metal workpiece.

[0054] A slider 13 is slidably arranged inside the carry slot 11, and the pressing roller 12 is installed through the slider 13. The slider 13 slides and presses inside the carry slot 11.

[0055] A first spring 14 is fixedly connected to the side surface of the slider 13. The slider 13 presses against the inner side of the carry slot 11 through the first spring 14. When the pressing roller 12 presses against the surface of the metal workpiece and is squeezed by the metal workpiece, the first spring 14 deforms to buffer the squeezing effect, avoiding losses caused by excessive friction between the pressing roller 12 and the metal workpiece.

[0056] An installation shaft 15 is fixedly connected to the side surface of the slider 13, and the pressing roller 12 is sleeved on the side surface of the installation shaft 15 through a bearing.

[0057] An installation sleeve 16 is fixed to the side surface of the splash-proof tooling 6. One end of the first spring 14 away from the slider 13 extends into the inner side of the installation sleeve 16. The installation sleeve 16 can prevent the first spring 14 deformed by extrusion from undergoing uncontrolled deformation.

[0058] According to the attached Figure 6 and the attached Figure 7 As shown, a baffle 17 is inserted on the side surface of the carry platform 5, and a second spring 18 is arranged between the baffle 17 and the carry platform 5 in a pressing manner. The baffle 17 is pressed against one side of the splash-proof tooling 6 through the second spring 18. As the slider 13 slides in the carry slot 11, the baffle 17 undergoes a carry change accordingly, ensuring that the baffle 17 always blocks the pressing roller 12.

[0059] A convex block 19 is fixedly connected to the side surface of the baffle 17, and one end of the second spring 18 is fixedly connected to the side surface of the convex block 19. The second spring 18 presses against the baffle 17 through the convex block 19.

[0060] One end of the baffle 17 close to the installation shaft 15 is fixedly connected to a pressing sleeve 20, and the pressing sleeve 20 presses against the installation shaft 15 to ensure the relative position between the baffle 17 and the pressing roller 12.

[0061] A lead screw 21 is fixedly connected to the side surface of the carry platform 5 corresponding to the second spring 18, and the installation of the second spring 18 can be positioned through the lead screw 21.

[0062] A tightening nut 22 is threadedly sleeved on the side surface of the lead screw 21, and the magnitude of the elastic force exerted by the second spring 18 on the baffle 17 is controlled by the position of the tightening nut 22 on the side surface of the lead screw 21.

[0063] A forming method of a spinning forming device:

[0064] S1. After installing the spinning tooling on the end of the main shaft 1, adjust the installation position of the cooling oil tank 4 and the lifting height of the lifting rod 3 according to the tooling, so that the cooling oil tank 4 can submerge the metal workpiece to a certain height for cooling after rising;

[0065] Check the oil in the cooling oil tank 4 to ensure the cooling effect of the cooling oil, and then correspondingly match the splash-proof tooling 6. Different splash-proof toolings 6 ensure tight contact with the surface of the metal workpiece, thus preventing the splashing of the cooling oil brought up by the rotating metal workpiece;

[0066] S2. Install the metal blank on the end of the main shaft 1, start the operation of the spinning wheel frame 2 to spin-process the metal blank. The feeding table 5 advances synchronously with the spinning wheel frame 2 to ensure tight contact between the splash-proof tooling 6 and the side of the metal blank. The reversely rotating metal workpiece and the splash-proof tooling 6 can strip the cooling oil brought up by inertia from the surface of the metal workpiece;

[0067] S3. The main shaft 1 drives the metal blank to rotate. The spinning wheel presses against the surface of the metal blank to apply pressure. The splash-proof tooling 6 presses against the height of the metal blank close to the liquid level of the cooling oil tank 4, presses against the surface of the metal blank and rotates to strip the cooling oil brought up from the surface of the metal blank.

[0068] In this spinning forming equipment and its spinning forming method, a liftable cooling oil tank 4 is arranged below the main shaft 1 to submerge the spinning workpiece for cooling, increasing the contact between the workpiece and the cooling oil, and avoiding factors such as short contact time and gas isolation on the contact surface in spray oil cooling that affect the cooling effect. In addition, to avoid the problem of splashing of the cooling oil caused by the rotation of the workpiece, the feeding table 5 and the splash-proof tooling 6 are also associated with the feeding setting of the spinning wheel frame 2. The attached oil is stripped by the pressing rollers 12 pressing against the surface of the workpiece, ensuring the rotation speed of the equipment, and thus improving the processing efficiency of the equipment.

[0069] Furthermore, the liftable cooling oil tank 4 is used to replace the spray oil cooling in the prior art. On the one hand, the contact time between the cooling oil in spray oil cooling and the surface of the workpiece is short, and it is easy to generate gas isolation on the contact surface between the metal workpiece and the oil, affecting heat conduction. On the other hand, the contact area between the spinning workpiece and the cooling oil is increased, thus better ensuring the cooling effect.

[0070] Still further, a feeding table 5 is symmetrically arranged on one side of the main shaft 1 and associated with the spinning wheel frame 2. With the feeding drive of the spinning wheel frame 2, the feeding table 5 and the splash-proof tooling 6 on the side of the feeding table 5 advance, ensuring tight contact between the splash-proof tooling 6 and the surface of the spinning workpiece, and stripping the cooling oil brought up by the rotating workpiece by the pressing rollers 12 to avoid splashing.

[0071] Furthermore, a pressing roller 12 is arranged on the side of the splash-proof tooling 6 and abuts against the surface of the workpiece through a first spring 14. The pressing roller 12 is in rolling contact with the surface of the workpiece, and the first spring 14 buffers the pressing of the workpiece against the pressing roller 12. On the one hand, the rolling friction has a smaller resistance than the sliding friction, which ensures the peeling effect of the cooling oil while reducing the friction loss of the splash-proof tooling 6. On the other hand, the deformation of the first spring 14 buffers the wear of the splash-proof tooling 6 and ensures the pressing state between the two.

[0072] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will also have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
