Description

Technical Field

[0001] The invention relates to a spin forming device for workpiece surface groove processing equipment, which is mainly used for performing surface groove spin forming processing on a workpiece in a rotating process. Background Art

[0002] Existing workpieces, such as pulleys, often need to be grooved on the surface of the workpiece blank by corresponding workpiece surface groove processing equipment. The existing workpiece surface groove processing equipment generally includes a workpiece rotation driving device for rotating the blank workpiece and a spinning forming device for spinning the groove on the surface of the workpiece.

[0003] The existing workpiece surface groove processing equipment uses a spinning forming device which mainly includes a fixed seat driven by a corresponding mobile driving mechanism and a spinning mechanism installed on the fixed seat. The spinning mechanism generally includes a spinning wheel, which is rotated and installed on the fixed seat through a corresponding connecting piece. During the processing, the fixed seat and the spinning wheel are driven into place by the mobile driving mechanism so that the spinning wheel contacts the surface of the workpiece, thereby performing surface groove processing on the surface of the workpiece during the rotation process. The spinning wheel is prone to a certain degree of temperature rise during the spinning process on the workpiece surface. Since the temperature rise is relatively small compared to the temperature rise of other machining processes, some spinning forming devices do not directly set up a cooling system, resulting in a small amount of deformation of the spinning wheel after heating, thereby affecting the processing accuracy; and some spinning forming devices with higher processing accuracy requirements use a direct spraying method of coolant to cool the contact position between the spinning wheel and the workpiece, which consumes a large amount of coolant. In addition, a coolant recovery circulation system needs to be set up, resulting in relatively high processing costs.

[0004] Therefore, the research purpose of the present invention is to design a spinning forming device for workpiece surface groove processing equipment that can achieve uniform cooling and temperature reduction treatment of the spinning wheel at a low cost, thereby effectively maintaining the spinning processing accuracy of the spinning wheel on the workpiece. Summary of the invention

[0008] During the rotation of the spinning wheel, the connecting shaft drives the fixed shaft and the driving shaft to rotate respectively, so as to drive the fan to rotate and inject the atomized coolant into the installation groove along the conduit, and at the same time drive the arc blade plate to rotate to push out the cooling atomized liquid in the installation groove to cool the spinning wheel.

[0009] A group of sealing plates located on the upper and lower sides of the guide hole are fixedly connected to the inner side of the partition according to height, and corresponding magnets are fixedly connected to both sides of the sealing plate.

[0010] When the spinning wheel stops rotating, under the action of the magnetic attraction force between the magnetic metal piece and the magnet, the magnetic metal piece close to and facing the magnet is adsorbed and connected to the magnet, so that the arc-shaped blade plate and the sealing plate cooperate to close the guide hole on the partition.

[0011] The belt transmission ratio between the connecting shaft and the fixed shaft, and the transmission ratio between the fixed shaft and the driving shaft of the fan are both greater than 2.

[0012] A coolant adding port is arranged on the top of the coolant container, and a corresponding sealing cover is detachably mounted on the coolant adding port.

The driving power source of the several arc-shaped blade plates and the fan directly adopts the spinning wheel itself, so that during the rotation of the spinning wheel, that is, during the processing of the spinning wheel, the atomized coolant is synchronously output to cool the spinning wheel. It can reduce the consumption of coolant and the energy consumption required for driving the arc-shaped blade plates and the fan; and it can prevent the coolant from being continuously output to the spinning wheel that is not rotating, so as to prevent the temperature of the spinning wheel as a whole from being uneven, thereby ensuring the practical effect of the present invention.

[0018] 3) A group of sealing plates are fixedly connected to the inner side of the partition of the present invention according to the height, and corresponding magnets are fixedly connected to the two sides of the sealing plates respectively. The rotating wheel is rotatably installed on the fixed shaft through the corresponding one-way bearings. Along the rotatable direction of the one-way bearings, magnetic metal parts corresponding to the magnets are fixedly connected to the front side surfaces of the outer ends of the arc-shaped blade plates respectively, and the distance between the ends of two or more adjacent arc-shaped blade plates is equal to the distance between the two magnets. When the spinning wheel stops rotating, under the action of the magnetic attraction of the magnetic metal parts and the magnets, the magnetic metal parts close to and facing the magnets are adsorbed and connected to the magnets, so that the arc-shaped blade plates and the sealing plates cooperate to form a closure on the guide holes on the partition. This is to further ensure that when the spinning wheel is not rotating, the atomized coolant is not output, thereby further ensuring the overall temperature uniformity of the spinning wheel, and further ensuring the practical effect of the present invention.

[0019] 4) In the present invention, the belt transmission ratio of the connecting shaft and the fixed shaft, as well as the transmission ratio of the fixed shaft and the driving shaft of the fan are both greater than 2, so as to gradually increase the rotation speed of the arc blade plate and the fan, thereby effectively maintaining the rotation speed of the arc blade plate and the fan at a relatively high condition, so as to further ensure the practical effect of the present invention.

A corresponding partition plate 4 is fixedly connected to the mounting groove 3011 inside the spinning wheel 302. A corresponding guide hole 401 is provided in the middle of the partition plate 4. The two sides of the mounting groove 3011 inside the partition plate 4 are respectively fixedly connected with corresponding closing plates 402. The cooling liquid atomizing mechanism 303 comprises a cooling liquid container 3031 fixedly connected to the top of the connecting member 301, wherein an ultrasonic atomizing sheet 3032 for processing the cooling liquid into atomized liquid is fixedly installed in the cooling liquid container 3031; The cooling atomized liquid circulation mechanism 304 comprises a conduit 3041 which penetrates and is installed on the top of the connecting member 301, the bottom of the conduit 3041 is connected to the mounting groove 3011 on the inner side of the partition 4, the top of the conduit 3041 extends to the upper side of the cooling liquid container 3031, a corresponding fan 3042 is fixedly installed on the upper part of the cooling liquid container 3031, and the driving shaft 5 of the fan 3042 is transmission-connected to the connecting shaft 3021; The cooling atomized liquid pushing mechanism 305 includes a plurality of arc-shaped blade plates 3051 rotatably arranged in the mounting groove 3011 on the inner side of the partition 4; when the spinning wheel 302 rotates, the plurality of arc-shaped blade plates 3051 rotate to push out the cooling atomized liquid in the mounting groove 3011 to cool the spinning wheel 302.

[0026] The top of the connecting piece 301 of the present invention is arranged horizontally, so that the coolant container 3031 of the coolant atomizing mechanism 303 can be fixedly installed on the top of the connecting piece 301; by adding a cooling atomized liquid circulation mechanism 304, the atomized coolant can be synchronously blown into the mounting groove 3011 on the inner side of the partition 4 during the rotation of the spinning wheel 302; and then by adding a cooling atomized liquid pushing mechanism 305, the atomized coolant can be continuously pushed out of the guide hole 401 of the partition 4 during the rotation of the spinning wheel 302, so that it can directly and evenly adhere to the spinning wheel 302 in the rotating process, thereby achieving uniform cooling of the spinning wheel 302, so as to achieve uniform cooling and temperature reduction treatment of the spinning wheel 302 at a low cost, thereby effectively maintaining the spinning processing accuracy of the spinning wheel 302 on the workpiece.

[0027] A plurality of the arc-shaped blade plates 3051 are fixedly connected to the corresponding rotating wheels 3052 at equal intervals, and the rotating wheels 3052 are rotatably mounted on the connecting member 301 through the corresponding fixed shafts 3053; the driving shaft 5 of the fan 3042 is connected to the fixed shaft 3053 through a belt drive, and the fixed shaft is connected to the connecting shaft 3021 through a belt drive.

[0028] During the rotation of the spinning wheel 302, the connecting shaft 3021 drives the fixed shaft 3053 and the fan 3042 to rotate respectively, so as to drive the fan 3042 to rotate and inject the atomized coolant into the installation groove 3011 along the conduit 3041, and at the same time drive the arc blade plate 3051 to rotate, so as to push out the cooling atomized liquid in the installation groove 3011 to cool the spinning wheel 302.

[0029] The driving power source of the plurality of arc-shaped blade plates 3051 and the fan 3042 is directly the spinning wheel 302 itself, so that during the rotation of the spinning wheel 302, i.e., during the processing of the spinning wheel 302, the atomized coolant is synchronously output to cool the spinning wheel 302. This can reduce the consumption of coolant and the energy consumption required for driving the arc-shaped blade plates 3051 and the fan 3042; and can prevent the coolant from being continuously output to the spinning wheel 302 that is not rotating, so as to prevent the spinning wheel 302 from having uneven temperature as a whole and causing slight deformation, thereby ensuring the practical effect of the present invention.

[0031] When the spinning wheel 302 stops rotating, under the action of the magnetic attraction force between the magnetic metal piece 9 and the magnet 7, the magnetic metal piece 9 close to and facing the magnet 7 is adsorbed and connected to the magnet 7, so that the arc blade plate 3051 cooperates with the sealing plate 6 to seal the guide hole on the partition 4. This further ensures that the atomized coolant is not output when the spinning wheel is not rotating, thereby further ensuring the overall temperature uniformity of the spinning wheel and further ensuring the practical effect of the present invention.

[0032] The belt transmission ratio of the connecting shaft 3021 and the fixed shaft 3053, and the transmission ratio of the fixed shaft 3053 and the driving shaft 5 of the fan 3042 are both greater than 2. The rotation speeds of the arc blade plate 3051 and the fan 3042 are gradually increased, thereby effectively maintaining the rotation speeds of the arc blade plate 3051 and the fan 3042 at a relatively high condition, so as to further ensure the practical effect of the present invention.

[0033] The top of the coolant container 3031 is provided with a coolant adding port, and a corresponding cover 10 is detachably installed at the coolant adding port. Through the matching arrangement of the coolant adding port and the cover 10, convenient addition of coolant is effectively achieved, thereby improving the practical effect of the present invention.
