[0047] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0048] The present invention provides Figure 1-10 The forging device for machining a guide wheel hub shown in the figure comprises a pedestal 1 and also comprises:

[0049] Forging hammers 2, the number of which is set to two, and a bidirectional forging mechanism 3 is provided on one side of the forging hammer 2, which is used to drive the two forging hammers 2 to forge the upper and lower end surfaces of the wheel hub blank respectively;

[0050] It should be noted that the two forging hammers 2 are respectively located on the upper and lower sides of the wheel hub blank, and the two forging hammers 2 can be driven by the bidirectional forging mechanism 3 to simultaneously approach the wheel hub blank located therebetween, so that the two forging hammers 2 forge the upper and lower end faces of the wheel hub blank at the same time. The wheel hub blank can be subjected to similar forging forces and process conditions on the upper and lower end faces, thereby improving the uniformity and consistency of the finished wheel hub product, which is beneficial to avoiding uneven stress distribution in the finished wheel hub product due to unidirectional forging.

[0051] Moreover, when the two forging hammers 2 are forging, one of the forging hammers 2 can serve as a support for the other forging hammer 2, so that the force on the hub blank is more even. The two forging hammers 2 apply opposite forces respectively, so that the force on the hub blank in the upper and lower directions is balanced. Moreover, since the impact directions of the two forging hammers 2 are opposite, the impact forces of the two forging hammers 2 can offset each other to a part, which can reduce the vibration during the forging process.

[0052] In addition, the two forging hammers 2 simultaneously impact the wheel hub blank for forging, which can improve work efficiency and shorten the forging cycle.

[0053] A movable clamp 4, which is located between the two forging hammers 2 and is used to clamp the hub blank. A supporting mechanism 5 is provided outside the movable clamp 4 to support the movable clamp 4;

[0054] It should be noted that the movable clamp 4 clamps the hub blank from the side, and the support mechanism 5 is used to support the movable clamp 4. The support mechanism 5 is provided with two parts, and the two parts are movably connected, one part of which is fixed on the pedestal 1, and the other part is connected to the movable clamp 4;

[0055] With the support of the supporting mechanism 5, the movable clamp 4 can not only rotate on its own to facilitate rotary forging, but also has an adjustable gap in the vertical direction, so that the movable clamp 4 can move within a certain range with the wheel hub blank, so as to buffer the forging of the forging hammer 2 and prevent the vibration caused by the forging hammer 2 from being transmitted to the entire device.

[0056] When the two forging hammers 2 do not touch the wheel hub blank at the same time, one of the forging hammers 2 can push the wheel hub blank and the movable clamp 4 toward the other forging hammer 2, so that the movable clamp 4 has a certain degree of freedom in the vertical direction to prevent the forging hammer 2 from causing damage to the movable clamp 4 during forging.

[0057] The ratchet wheel 6 is arranged outside the supporting mechanism 5 , a pawl 7 is arranged on one side of the ratchet wheel 6 , a driving mechanism 8 is arranged at one end of the pawl 7 , and the driving mechanism 8 is connected to the bidirectional forging mechanism 3 .

[0058] It should be noted that the pawl 7 is connected to the bidirectional forging mechanism 3 through the driving mechanism 8. When the bidirectional forging mechanism 3 drives the forging hammer 2 to forge the wheel hub blank, the pawl 7 can be driven to reciprocate, thereby driving the ratchet 6 matched with the pawl 7 to rotate. The ratchet 6 is connected to the movable part of the supporting mechanism 5, which can drive the movable clamp 4 to rotate. Every time the bidirectional forging mechanism 3 drives the forging hammer 2 to forge once, the driving mechanism 8 can drive the pawl 7 to push the ratchet 6 to rotate once, thereby realizing automatic rotary forging.

[0059] The forging hammer 2 includes a hammer body 21, a hammer head 22 and a guide slide block 23;

[0060] The hammer head 22 is installed at one end of the hammer body 21 , and the number of the guide slide blocks 23 is set to two groups, and the two groups of guide slide blocks 23 are respectively fixed on both sides of the hammer body 21 .

[0061] It should be noted that the two forging hammers 2 are mirror-imaged on the upper and lower sides of the hub blank, and the two hammer heads 22 are both arranged at one end of the hammer body 21 close to the hub blank, and the other end of the hammer body 21 is connected to the bidirectional forging mechanism 3, and the two sets of guide sliders 23 are used to limit the moving direction of the forging hammer 2, so that the forging hammer 2 can keep moving vertically, so as to facilitate accurate forging;

[0062] The bidirectional forging mechanism 3 includes a support frame 31, a guide rail 32, a gear 33, a swing arm 34 and a double connecting rod 35;

[0063] The support frame 31 is connected to the pedestal 1, and the guide rail 32 is installed on the support frame 31. The number of the guide rails 32 is set to two groups, and the two groups of guide rails 32 correspond to two forging hammers 2 respectively. The guide slider 23 is slidably connected to the guide rail 32. The number of the gears 33 is set to two, and two gears 33 are installed on the support frame 31. The two gears 33 are meshed with each other. The number of the swing arms 34 is set to two, and one end of the two swing arms 34 is fixedly connected to the two gears 33 respectively, and the other ends of the two swing arms 34 are respectively connected to two double connecting rods 35.

[0064] It should be noted that the double connecting rod 1 35 is composed of two mutually hinged planar connecting rods, which can transmit the swing of the two swing arms 34 to the forging hammer 2. The two swing arms 34 are arranged in a mirror image, and the two swing arms 34 can be driven to move in a mirror image through the meshing of the two gears 33, so that the two forging hammers 2 can move in a mirror image. The guide slide rail 32 cooperates with the guide sliders 23 on both sides of the hammer body 21 to guide the forging hammer 2.

[0065] The bidirectional forging mechanism 3 also includes a forging cylinder 36 and a spindle 37;

[0066] The forging cylinder 36 is arranged at the end of the support frame 31, one end of the main shaft 37 is connected to the output shaft of the forging cylinder 36, the other end of the main shaft 37 is connected to one of the hammer bodies 21, one of the double connecting rods 35 is connected to the main shaft 37, and the other double connecting rod 35 is connected to the other hammer body 21.

[0067] It should be noted that the double connecting rod 35 connected to the main shaft 37 provides power to the two meshing gears 33 through the swing arm 34, so that the two double connecting rods 35 can move in a mirror image, and then the other forging hammer 2 which is not directly connected to the main shaft 37 can move under the power of the main shaft 37.

[0068] In actual use, the forging cylinder 36 provides power to the main shaft 37, so that the main shaft 37 drives the forging hammer 2 connected thereto to move downward for forging. At the same time, the main shaft 37 drives the gear 33 through the double connecting rod 1 35 connected thereto, and then through the swing arm 34 hinged to the double connecting rod 1 35, so that another gear 33 drives another swing arm 34 to move upward (the rotation direction of the meshing gears is opposite), and then drives another forging hammer 2 through the double connecting rod 1 35, so that the other forging hammer 2 moves upward for forging, thereby realizing the forging of the two end faces of the hub blank at the same time.

[0069] The support mechanism 5 includes a movable ring 51 and an inner limiting ring 52;

[0070] The movable ring 51 is arranged outside the movable clamp 4, and the ratchet 6 is fixed outside the movable ring 51. The inner limit rings 52 are arranged in two, and the two inner limit rings 52 are respectively arranged on the upper and lower sides of the ratchet 6. The movable ring 51 is rotatably connected with the inner limit rings 52.

[0071] It should be noted that the movable clamp 4 is installed on the inner side of the movable ring 51. The ratchet 6 is driven by the pawl 7, which can drive the movable ring 51 connected to the ratchet 6 to rotate, and then drive the movable clamp 4 inside the movable ring 51 to rotate, so that the movable clamp 4 drives the hub blank to rotate.

[0072] The support mechanism 5 also includes an outer fixing ring 53, a support column 54 and a buffer spring 55;

[0073] The number of the outer fixing rings 53 is set to two, and the two outer fixing rings 53 are respectively located on the upper and lower sides of the two inner limit rings 52, the support column 54 passes through the outer fixing ring 53 and the inner limit ring 52 and is connected to the pedestal 1, the outer fixing ring 53 is fixedly connected to the support column 54, and the inner limit ring 52 is slidably connected to the support column 54, and the buffer spring 55 is sleeved on the outside of the support column 54, and the number of the buffer springs 55 is set to two groups, and the two groups of buffer springs 55 are respectively located between the two outer fixing rings 53 and the two inner limit rings 52.

[0074] It should be noted that the outer fixing ring 53 is connected to the inner limiting ring 52 through the support column 54, which can ensure that the inner limiting ring 52 is connected by sliding up and down along the support column 54. The buffer spring 55 is arranged between the inner limiting ring 52 and the outer fixing ring 53, which can buffer the sliding of the inner limiting ring 52, so that the movable clamp 4 inside the movable ring 51 can move up and down.

[0075] In actual use, the bidirectional forging mechanism 3 drives the two forging hammers 2 for forging, and when the wheel hub blank is forged and impacted by the forging hammers 2, the movable clamp 4 can move up and down accordingly, and is buffered by the buffer spring 55 between the inner limit ring 52 and the outer fixed ring 53. When the bidirectional forging mechanism 3 drives the forging hammer 2 to reset, the ratchet 7 can be driven by the driving mechanism 8, thereby driving the movable ring 51 connected to the ratchet 6 to rotate, and then driving the movable clamp 4 inside the movable ring 51 to rotate, so that the movable clamp 4 drives the wheel hub blank to rotate.

[0076] The driving mechanism 8 includes a driving slider 81, a guide slider 82, a driving shaft 83, a double connecting rod 84 and a spring 85;

[0077] One end of the driving slider 81 is hinged to the pawl 7, the guide slide rod 82 is installed on one side of the driving slider 81, the guide slide rod 82 passes through the support frame 31 and is slidably connected to the support frame 31, the spring piece 85 is arranged between the guide slide rod 82 and the pawl 7, the number of the driving shafts 83 is set to two, the two driving shafts 83 are respectively fixedly connected to the two gears 33, and the two ends of the double connecting rod 84 are respectively connected to the driving shaft 83 and the driving slider 81.

[0078] It should be noted that the guide slide bar 82 can limit the driving slide bar 81, so that the driving slide bar 81 slides along the direction of the guide slide bar 82, and the gear 33 drives the double connecting rod 2 84 to rotate, thereby driving the driving slide bar 81 to move, so that it drives the pawl 7 to drive the ratchet 6 to rotate;

[0079] Furthermore, since the two double connecting rods 84 are respectively connected to the gear 33 and the driving slider 81, when the transmission of the two gears 33 is about to cause transmission problems such as tooth jumping, the gear 33 transmits one of the double connecting rods 84 through the driving shaft 83, thereby transmitting the movement of the driving slider 81, and the driving slider 81 drives the other double connecting rod 84 to move, thereby transmitting the rotation of the other gear 33 connected to the driving shaft 83, thereby avoiding the occurrence of transmission problems such as tooth jumping.

[0080] In actual use, when the forging hammer 2 is reset, the two swing arms 34 move away from each other in a mirror image, so that the gear 33 drives the double connecting rod 2 84 to move through the drive shaft 83, and then transmits the drive slider 81, so that the pawl 7 drives the ratchet 6 to rotate, and the pawl 7 can be close to the ratchet 6 through the spring piece 85.

[0081] The movable clamp 4 includes a mounting ring 41, a positioning ring 42, a clamping claw 43, a connecting rod 44 and a fastening screw 45;

[0082] The mounting ring 41 includes an interior portion fixed to the movable ring 51, the positioning ring 42 is arranged at the top of the mounting ring 41, the positioning ring 42 is rotatably connected to the mounting ring 41, the number of the clamping jaws 43 and the connecting rod 44 is set to be multiple, and the multiple clamping jaws 43 are distributed in a circular array on the inner side of the mounting ring 41, one end of the clamping jaw 43 is hinged to the mounting ring 41, the other end of the clamping jaw 43 is hinged to the connecting rod 44, and the end of the connecting rod 44 away from the clamping jaw 43 is hinged to the positioning ring 42, the fastening screw 45 passes through the positioning ring 42 and extends to the top end surface of the mounting ring 41, and the fastening screw 45 is threadedly connected to the positioning ring 42.

[0083] It should be noted that the side of the clamping jaw 43 close to the wheel hub blank is set in a V shape, which can prevent the clamped wheel hub blank from slipping;

[0084] In actual use, by rotating the positioning ring 42, multiple connecting rods 44 are driven to move, and multiple clamps 43 can be driven by the connecting rods 44 to move simultaneously to center and clamp the hub blank, and by using the fastening screws 45, the positioning ring 42 and the mounting ring 41 are connected together.

[0085] Working principle of the present invention:

[0086] Refer to the instruction manual Figure 1-10 First, the circular wheel hub blank is clamped by the movable clamp 4, and then the forging cylinder 36 is started. The forging cylinder 36 provides power to the main shaft 37, so that the main shaft 37 drives the forging hammer 2 connected thereto to move downward for forging. At the same time, the main shaft 37 drives the gear 33 through the double connecting rod 1 35 connected thereto, and then drives the gear 33 through the swing arm 34 hinged to the double connecting rod 1 35, so that another gear 33 drives another swing arm 34 to move upward, and then drives another forging hammer 2 through the double connecting rod 1 35, so that another forging hammer 2 moves upward for forging, thereby realizing forging of the two end faces of the wheel hub blank at the same time, so that the wheel hub blank can be subjected to similar forging force and process conditions on the upper and lower end faces, thereby improving the uniformity and consistency of the finished wheel hub, which is conducive to avoiding uneven stress distribution in the finished wheel hub due to unidirectional forging;

[0087] At the same time, when the bidirectional forging mechanism 3 drives the forging hammer 2 to reset, the ratchet 7 can be driven by the driving mechanism 8, thereby driving the movable ring 51 connected to the ratchet 6 to rotate, and then driving the movable clamp 4 inside the movable ring 51 to rotate, so that the movable clamp 4 drives the wheel hub blank to rotate, so that the wheel hub blank can be forged in all directions, thereby improving the forging effect.

[0088] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
