Description

Technical Field

[0003] Among them, during the ring forging process, since the support shaft and the pressure roller need to contact the high-temperature forging, and both the pressure roller and the support shaft need to be rotatably connected to the ring forging device. When contacting and ring forging the high-temperature forging, the support shaft and the pressure roller are prone to deformation or cracking problems. Therefore, in the conventional method, workers hold the water pipe by hand and spray water on the blank. During the process of spraying water on the blank, some water will also be sprayed on the pressure roller and the support shaft to cool them down. In this process, the water can also remove the scale on the blank during the ring forging process.

[0004] However, in this process, the water spraying is manually controlled, and workers need to stand near the ring forging device. When the ring forging device forges the high-temperature blank, the vicinity is also in a high-temperature state. The labor intensity of the operator is relatively high, and there is a risk of being scalded. The spraying angle is also set arbitrarily, and there are many places that cannot be sprayed, resulting in poor cooling effect of the equipment. Or the water is sprayed into the motor of the equipment, causing potential safety hazards or damage. Summary of the Invention

[0033] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments:

[0034] Embodiment 1: Refer to Figures 1-4 As shown, a ring forging device includes a machine body 1, a support roller 2 rotatably installed on the machine body 1, and a pressing roller 3 disposed above the support roller 2. The pressing roller 3 is installed on the machine body 1 via a bracket 4. The pressing roller 3 is rotatably connected to the bracket 4. The machine body 1 is configured to drive the pressing roller 3 to rotate and drive the bracket 4 to approach or move away from the support roller 2.

[0035] A water outlet pipe 5 is rotatably installed on each side of the bracket 4. The water outlet pipe 5 is arranged parallel to the axis of the pressing roller 3. The two water outlet pipes 5 are respectively arranged on the left and right sides above the axis of the pressing roller 3.

[0036] A cavity 6 is provided in the water outlet pipe 5. One end of the water outlet pipe 5 is provided with a connector 7 communicating with the cavity 6. A water supply pipe 8 is connected to the connector 7.

[0037] A plurality of water outlet holes 9 are arranged at intervals along the axial direction at the bottom of each water outlet pipe 5. The water outlet holes 9 are communicated with the cavity 6.

[0038] In this embodiment, during ring forging, a high-temperature blank is placed on the support rollers. Then, while the machine body drives the pressure roller to rotate, it also drives the pressure roller to move downward so that the pressure roller abuts against the top surface of the high-temperature blank, thereby performing ring forging on the high-temperature blank. During this process, the water supply pipe supplies water to the water outlet pipe, sending water into the cavity of the water outlet pipe, and then flowing through the water outlet holes to the outer surface of the top of the pressure roller. During this process, the water will also flow along the pressure roller to the outer surfaces of the high-temperature forging and the support rollers, cooling the pressure roller and the support rollers and cleaning the oxide scale on the surface of the high-temperature forging to a certain extent. In this way, there is no need for manual cooling of the pressure roller and the support rollers. The operator does not need to stand beside the ring forging equipment for a long time and be affected by the high temperature of the high-temperature blank, which can improve the operator's operation experience and prevent the operator from being scalded, reducing potential safety hazards. Furthermore, the water outlet holes are arranged at intervals along the axial direction of the water outlet pipe, so that the water flowing out of the water outlet holes can flow to the outer surface arranged along the axis of the pressure roller. Through the rotation of the pressure roller, the water can always be sprayed on the outer surface of the pressure roller to cool it. Further, the water outlet pipe is rotatably connected to the bracket, so that the water outlet position and angle of the water outlet holes can be adjusted, and the equipment and the high-temperature blank can be sprayed with water for cooling.

[0039] See Figures 1-3 As shown, a driving mechanism 10 is further provided on the bracket 4 beside each water outlet pipe 5, and the driving mechanism 10 is configured to drive the corresponding water outlet pipe 5 to rotate.

[0040] In this embodiment, the driving mechanism is used to drive the water outlet pipe to rotate, realizing automatic adjustment of the bottom water outlet angle of the water outlet pipe without manual adjustment.

[0041] See Figures 1-3 As shown, the driving mechanism 10 includes a motor 11 and a first gear 12. The motor 11 is installed on the bracket 4, and the first gear 12 is installed on the output shaft of the motor 11;

[0042] A second gear 13 is provided on the outer surface of the water outlet pipe 5, and the first gear 12 meshes with the second gear 13.

[0043] In this embodiment, the motor is directly installed on the bracket, and the second gear is installed on the outer surface of the water outlet pipe. The first gear on the output shaft of the motor meshes with the second gear to drive the water outlet pipe to rotate. In this way, the motor does not occupy the axial space of the water outlet pipe, enabling the length of the water outlet pipe to be set longer than the length of the pressure roller. It also does not affect the taking and placing of the high-temperature blank, and during the process of taking and placing the high-temperature blank, the motor will not be collided with and damaged.

[0044] See Figures 1-4As shown, both ends of the water outlet pipe 5 are respectively connected to the side parts of the bracket 4 via connecting plates 14, and both ends of the water outlet pipe 5 are respectively rotatably connected to the two connecting plates 14.

[0045] A convex part 15 is provided on the outer wall of the water outlet pipe 5, and the convex part 15 is arranged beside one of the connecting plates 14;

[0046] Two stop blocks 16 are provided on the connecting plate 14 beside the convex part 15, and the convex part 15 is arranged between the two stop blocks 16;

[0047] When the water outlet pipe 5 rotates towards the first direction, the convex part 15 is limited by one of the stop blocks 16, and when the water outlet pipe 5 rotates towards the second direction, the convex part 15 is limited by the other stop block 16.

[0048] In this embodiment, there is a certain distance between the two stop blocks, and the width of the convex part is smaller than this distance. Therefore, the water outlet pipe can rotate by a certain angle. After it rotates by a certain angle towards the first direction, one stop block will limit the convex part and the water outlet pipe from continuing to rotate. At this time, the water outlet pipe can only rotate towards the second direction. When the water outlet pipe rotates towards the second direction to a certain angle, the other support block will limit the convex part and the stop block from rotating. At this time, the water outlet pipe can only rotate towards the first direction. In this way, it can be ensured that the water outlet at the bottom of the water outlet pipe always faces downwards or is inclined downwards. The water flowing out of the water outlet holes will only spray onto the outer surface of the pressure roller or onto the outer surface of the hot forging. It will not spray to other positions, which is not only more environmentally friendly but also prevents the water from spraying onto other water-intolerant components of the ring forging equipment, preventing damage to the ring forging equipment.

[0049] See Figure 4 As shown, a touch sensor 17 is respectively provided on each of the stop blocks 16. The touch sensor 17 is arranged opposite to the convex part 15, and the touch sensor 17 is electrically controlled and connected to the corresponding motor 11.

[0050] With the setting of the touch sensor, after the motor drives the water outlet pipe to rotate to the limit position towards the first direction or the second direction, it will be limited by the corresponding stop block. After being limited, the touch sensor can detect it, so that the motor will not continue to drive in the corresponding direction and can only move in the reverse direction or pause, preventing damage to the motor.

[0051] Wherein, a shield 18 is further provided on the bracket 4 below each motor 11, and heat insulation layers 19 are respectively provided at the top and bottom of the shield 18. Since the high-temperature forging is located below the pressure roller and the temperature around it is relatively high, in order to prevent the motor from being affected by this high temperature for a long time and resulting in a shorter service life, therefore, through the setting of the shield and the heat insulation layers are respectively provided on both sides of the shield, which can effectively isolate the influence of high temperature on the motor. At the same time, it can also prevent the high-temperature water splashed after the water outlet pipe sprays water and contacts the high-temperature forging from reaching the motor, and prevent the high-temperature oxide scale from touching the motor and causing damage to the motor.

[0052] See Figure 1 、 2 As shown, the pressure roller 3 is arranged parallel directly above the support roller 2;

[0053] The rear side of the bracket 4 is vertically movably connected to the body 1. The bracket 4 is a U-shaped structure with an opening facing downwards. A U-shaped opening 20 is provided at the bottom of the bracket 4. Both ends of the pressure roller 3 are rotatably connected to both ends of the U-shaped opening 20. The left and right sides of the pressure roller 3 are respectively arranged outside the left and right sides of the bracket 4, and the bottom of the pressure roller 3 is arranged below the bottom of the bracket 4.

[0054] A first motor 21 is provided on the bracket 4. The first motor 21 is connected to the rear end of the pressure roller 3 through a speed reducer 22. The first motor 21 drives the pressure roller 3 to rotate through the speed reducer 22.

[0055] A hydraulic cylinder 23 is provided on the body 1. The output shaft of the hydraulic cylinder 23 is connected to the bracket 4. The hydraulic cylinder 23 is configured to drive the bracket 4 to move up and down.

[0056] In this embodiment, the pressure roller is driven to rotate by the first motor, and the bracket and the pressure roller are driven to move up and down by the hydraulic cylinder. In this process, the ring forging of the high-temperature blank by the pressure roller is realized, with a simple structure and strong stability. Moreover, using a hydraulic cylinder to drive the bracket to move up and down has sufficient power, so that the pressure of the pressure roller on the high-temperature blank can be realized, and the stable ring forging of the high-temperature blank can be achieved.
