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-in platform is provided on a symmetrical rotating wheel frame on one side of the main shaft, and the carry-in platform and the rotating wheel frame are synchronously carried. A splash-proof tooling is provided on the side of the carry-in platform. As the rotating wheel frame rotates, the splash-proof tooling fixed on the carry-in platform contacts the surface of the metal workpiece and rotates, blocking the cooling oil brought up by the metal workpiece to prevent splashing.

[0010] Preferably, a guide rail is fixed below the main shaft and along the main shaft direction, a mounting plate is slidably provided on the inner side of the guide rail, and the lifting rod is fixedly provided on the upper surface of the mounting plate. For spinning tooling of different specifications, it is necessary to adjust the installation position of the mounting plate on the guide rail according to processing needs, and control the lifting height of the lifting rod accordingly, locate the installation position of the mounting plate and set the height of the lifting rod.

[0011] Preferably, a transmission wheel is provided between the rotating wheel frame and the advancing platform, and the transmission wheel and the advancing rod ensure that the advancing platform changes position accordingly with the advancement of the rotating wheel frame, thereby ensuring that it always presses against the surface of the metal workpiece.

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

[0013] Preferably, a carry groove is provided on the side of the splash-proof tooling, and a clamping roller is slidably arranged on the inner side of the carry groove. The clamping roller is slidably installed in the carry groove to ensure that the clamping roller is pressed against the surface of the metal workpiece, while avoiding excessive friction contact between the clamping roller and the surface of the metal workpiece.

[0014] The splash-proof tooling blocks the cooling oil by pressing the pressing roller against the surface of the metal material, and the pressing roller moving synchronously with the rotating wheel frame can avoid obstruction to the metal workpiece.

[0015] Preferably, a slider is slidably provided on the inner side of the carry groove, the pressing roller is installed through the slider, and the slider slides and presses in the carry groove.

[0016] A first spring is fixedly connected to the side of the slider, and the slider is pressed against the inner side of the feed groove by the first spring. When the pressing roller is pressed against the surface of the metal workpiece, it is squeezed by the metal workpiece. The first spring deforms to buffer the squeezing effect, thereby avoiding losses caused by excessive friction between the pressing roller and the metal workpiece.

[0017] Preferably, a mounting shaft is fixedly connected to a side surface of the sliding block, and the pressing roller bearing is sleeved on the side surface of the mounting shaft.

[0018] A mounting sleeve is fixed to the side of the splash-proof tooling, and one end of the first spring away from the slider extends into the inner side of the mounting sleeve. The mounting sleeve can prevent the first spring that is squeezed and deformed from undergoing uncontrolled deformation.

[0019] Preferably, a baffle is inserted into the side of the carry platform, and 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 in position accordingly, ensuring that the baffle always blocks the pressing roller.

[0020] Preferably, a protrusion is fixedly connected to the side surface of the baffle, one end of the second spring is fixedly connected to the side surface of the protrusion, and the second spring is pressed against the baffle through the protrusion.

[0021] One end of the baffle plate close to the mounting shaft is fixedly connected with a clamping sleeve, and the clamping sleeve is pressed against the mounting shaft to ensure the relative position between the baffle plate and the clamping roller.

[0022] Preferably, a screw rod is fixedly connected to the side surface of the carrying platform corresponding to the second spring, and the installation of the second spring can be positioned by the screw rod.

[0023] The side surface of the screw rod is threadedly sleeved with a tightening nut, and the size of the elastic force applied by the second spring to the baffle is controlled by the position of the tightening nut on the side surface of the screw rod.

[0024] A forming method of a spin forming device: S1. After the spinning tool is installed on the end of the spindle, the setting position of the cooling oil tank and the lifting height of the lifting rod are adjusted according to the tool selection, so that the cooling oil tank can submerge the metal workpiece to a certain height for cooling after rising; Check the oil in the cooling oil tank to ensure the cooling effect of the cooling oil, and then match the splash-proof fixture accordingly. Different splash-proof fixtures ensure tight contact with the surface of the metal workpiece, thereby preventing the cooling oil from being splashed by the rotating metal workpiece; S2, installing the metal blank to the end of the spindle, starting to operate the rotating wheel frame to spin the metal blank, the advancing platform synchronously advances with the rotating wheel frame to ensure that the splash-proof tooling is in close contact with the side of the metal blank, and the metal workpiece and the splash-proof tooling rotating in the opposite direction can peel off the cooling oil brought up by inertia on the surface of the metal workpiece; S3. The main shaft drives the metal blank to rotate, the rotating wheel presses against the surface of the metal blank to apply pressure, the splash-proof tooling presses against the height of the metal blank close to the liquid level of the cooling oil tank, presses against the surface of the metal blank and rotates, peeling off the cooling oil brought up by the surface of the metal blank.

[0025] The present invention discloses a spin forming device and a spin forming method thereof, which have the following beneficial effects: 1. The spin forming equipment and the spin forming method thereof are provided with a liftable cooling oil tank under the main shaft to submerge the spun workpiece to help cool it down, increase the contact between the workpiece and the cooling oil, avoid factors that affect the cooling effect such as short contact time due to oil spray cooling and gas isolation on the contact surface. In addition, in order to avoid the problem of cooling oil splashing due to the rotation of the workpiece, an advance platform and a splash-proof tooling are also provided in conjunction with the advance of the spinning wheel frame, and the attached oil is peeled off by a pressing roller that is in close contact with the surface of the workpiece, thereby ensuring the rotation speed of the equipment and improving the processing efficiency of the equipment.

[0026] 2. The spin forming equipment and the spin forming method thereof use a lifting oil tank to replace the oil spray cooling in the prior art. On the one hand, the cooling oil of the oil spray cooling has a short contact time with the workpiece surface, which easily produces gas isolation at 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, thereby better ensuring the cooling effect.

[0027] 3. The spin forming equipment and the spin forming method thereof are provided with an advancing platform symmetrically on one side of the main shaft and associated with the rotating wheel frame. As the rotating wheel frame advances, the advancing platform and the splash-proof tooling on the side of the advancing platform are driven to advance, thereby ensuring that the splash-proof tooling is in close contact with the surface of the spun workpiece, and the cooling oil brought up by the rotating workpiece is peeled off by the pressing roller to avoid splashing.

[0028] 4. In the spin forming equipment and the spin forming method thereof, a pressing roller is arranged on the side of the splash-proof tooling to press against the surface of the workpiece through the first spring, the pressing roller is in rolling contact with the surface of the workpiece, and the workpiece is buffered by the first spring to press against the pressing roller. On the one hand, the rolling friction is smaller than the resistance of the sliding friction, thereby ensuring the stripping effect of the cooling oil while reducing the friction loss of the splash-proof tooling. On the other hand, the deformation of the first spring is used to buffer the wear of the splash-proof tooling, thereby ensuring the pressing state between the two. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] 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.

[0051] A forming method of a spin forming device: S1. After the spinning tool is installed at the end of the spindle 1, the setting position of the cooling oil tank 4 and the lifting height of the lifting rod 3 are adjusted according to the tool selection, so that the cooling oil tank 4 can submerge the metal workpiece to a certain height for cooling after it rises; Check the oil in the cooling oil tank 4 to ensure the cooling effect of the cooling oil, and then match the splash-proof tooling 6 accordingly. Different splash-proof tooling 6 ensures tight contact with the surface of the metal workpiece, thereby preventing the cooling oil from being splashed by the rotating metal workpiece; S2, the metal blank is mounted on the end of the spindle 1, and the rotating wheel frame 2 is started to spin the metal blank. The advancing table 5 is synchronously advanced with the rotating wheel frame 2 to ensure that the splash-proof tooling 6 is in close contact with the side of the metal blank. The metal workpiece and the splash-proof tooling 6 rotating in the opposite direction can peel off the cooling oil brought up by inertia on the surface of the metal workpiece; S3, the main shaft 1 drives the metal blank to rotate, the rotating 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, peeling off the cooling oil brought up by the surface of the metal blank.

[0052] The spin forming equipment and the spin forming method thereof are provided with a liftable cooling oil tank 4 below the main shaft 1 to submerge the spun workpiece to help cool it down, thereby increasing the contact between the workpiece and the cooling oil and avoiding factors that affect the cooling effect, such as short contact time due to oil spray cooling and gas isolation on the contact surface. In addition, in order to avoid the problem of splashing of cooling oil due to the rotation of the workpiece, an advance platform 5 and a splash-proof tooling 6 are also provided in conjunction with the advance of the spinning wheel frame 2. The adhered oil is peeled off by a pressing roller 12 that is in close contact with the surface of the workpiece, thereby ensuring the rotation speed of the equipment and improving the processing efficiency of the equipment.

[0053] Furthermore, the oil spray cooling of the prior art is replaced by a lifting cooling oil tank 4. On the one hand, the contact time between the cooling oil of the oil spray cooling and the workpiece surface is short, which easily produces gas isolation at the contact surface between the metal workpiece and the oil, affecting heat conduction. On the other hand, the contact area between the spun workpiece and the cooling oil is increased, thereby better ensuring the cooling effect.

[0054] Furthermore, an advancement platform 5 is symmetrically arranged on one side of the main shaft 1 and is associated with the rotating wheel frame 2. As the rotating wheel frame 2 advances, the advancement platform 5 and the splash-proof tooling 6 on the side of the advancement platform 5 are driven to advance, thereby ensuring that the splash-proof tooling 6 is in close contact with the surface of the spun workpiece, and the cooling oil brought up by the rotating workpiece is peeled off by the pressing roller 12 to avoid splashing.

The pressing roller 12 is in rolling contact with the surface of the workpiece, and the first spring 14 buffers the workpiece to press against the pressing roller 12. On the one hand, the rolling friction is smaller than the resistance of the sliding friction, thereby ensuring the stripping 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 to ensure the pressing state between the two.
