Description

Technical Field

[0001] The invention relates to the technical field of automobile half-axle forging processing devices, and in particular to a new energy automobile half-axle forging processing device. Background Art

[0002] The half shaft, also called the drive shaft, is the shaft that connects the differential to the drive wheel. At present, the production and processing steps of the half shafts required for new energy vehicles are as follows: the blank is heated and forged through a forging device, so that each position on the blank is forged to the required diameter, and has a larger diameter end, and after air cooling, the half shaft semi-finished product is obtained, and the larger diameter end of the half shaft semi-finished product is heated, and after heating, it is placed in a forging die for forging, so that the larger diameter end is forged into a disc shape under the action of the forming groove in the forging die, as shown in the attached figure. Figure 5 However, there are the following defects in this process:

[0003] When forging the end of the semi-finished half-axle product with a larger diameter in the forging die, most of the time, the forging die is manually clamped and rotated manually during forging, so that the forging equipment can evenly forge one end of the semi-finished half-axle product into the forming groove. However, the manual rotation method consumes a lot of manual labor and has certain risks. At the same time, before forging, there is a gap between one end of the semi-finished half-axle product placed in the forging die and the forming groove in the forging die, resulting in part of the iron oxide shavings on the semi-finished half-axle product falling into the forming groove in the forging die at the beginning of forging. If not removed in time, it will affect the subsequent forging quality of the semi-finished half-axle product. To this end, we propose a forging processing device for a new energy vehicle semi-axle.

DETAILED DESCRIPTION

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] Example 1

[0048] See also Figure 1 , a new energy vehicle half-axle forging processing device, comprising: a forging die 1, a support seat 2, a forging part 3 and an intermittent rotating component 4;

[0049] See also Figure 1 and Figure 5 The forging die 1 belongs to the prior art. Figure 1 As shown, it is cylindrical, with a through hole for the half-axle body to be forged to pass through at its center, and a circular forming groove at the top. In actual situations, after the half-axle semi-finished product has its end with a larger diameter heated, one end of the half-axle semi-finished product passes through the through hole of the forging die 1 downward, so that the heated end is placed in the forming groove, and then the end placed in the forming groove is forged by the forging part 3, so that the end placed in the forming groove forms a disc portion with the same diameter as the forming groove, and a preliminarily formed half-axle is obtained;

[0050] The support seat 2 is fitted at the bottom of the forging die 1 to support the forging die 1. A notch is provided on one side of the support seat 2 so that one end of the semi-finished half-shaft to be processed passes through the through hole in the forging die 1 downward. At the same time, an annular limiting convex edge 21 is provided at the top of the support seat 2 corresponding to the position of the forging die 1. The inner diameter of the annular limiting convex edge 21 matches the diameter of the forging die 1. In actual situations, the forging die 1 is placed in the annular limiting convex edge 21. The annular limiting convex edge 21 does not interfere with the rotation of the forging die 1, and the forging die 1 will not move on the outer wall of the support seat 2.

[0051] The forging part 3 includes a hammer head placed above the forging die 1 for forging one end of the semi-finished half-shaft in the forging die 1 placed in the forming groove, a driving device (not shown in the figure) for driving the hammer head to move up and down relative to the forging die 1, and a bracket (not shown in the figure) for mounting and supporting the driving device, etc. The forging part 3 can be conventional forging equipment widely used in the art;

[0052] The intermittent rotating assembly 4 is arranged on the outer wall of the support seat 2 and is used to intermittently drive the forging die 1 to rotate when the forging part 3 is forging, so as to ensure that one end of the semi-finished half-shaft is evenly forged.

[0053] Example 2

[0054] See also Figure 2-3 The intermittent rotating assembly 4 includes: a driving part 41, a support frame 42, an intermittent fixing part 43 and a driving part 44;

[0055] Among them, an annular groove is opened on the outer wall of the forging die 1, and the driving part 41 is sleeved on the outer wall of the annular groove to drive the forging die 1 to rotate;

[0056] A support frame 42, fixedly disposed on the outer wall of the support seat 2, for supporting the intermittent fixing portion 43, the driving portion 44 and the air guide portion 45;

[0057] The intermittent fixing part 43 is arranged on the supporting frame 42 and is used to drive the driving part 41 to clamp and fix the forging die 1 or to contact the forging die 1 to clamp and fix it;

[0058] The driving part 44 is disposed on the supporting frame 42 and is used to enable the driving part 41 to intermittently drive the forging die 1 to rotate within a certain angle range.

[0059] Example 3

[0060] See also Figure 3-4 , the driving part 41 includes: a tough arc strip 411 and a tough connecting strip 412;

[0061] The tough arc strip 411 is movably sleeved in the annular groove on the outer wall of the forging die 1;

[0062] The resilient connecting strips 412 are provided in two groups, and the two groups of resilient connecting strips 412 are integrally formed with both ends of the resilient arc-shaped strip 411 respectively;

[0063] In the initial state, that is, when the two groups of resilient connecting strips 412 do not approach each other, the inner wall of the resilient arc-shaped strip 411 will not apply clamping pressure to the outer wall of the annular groove of the forging die 1. When the two groups of resilient connecting strips 412 approach each other, the inner wall of the resilient arc-shaped strip 411 will apply pressure to the outer wall of the annular groove of the forging die 1. Thus, in this state, the driving part 41 can drive the forging die 1 to rotate;

[0064] It should be noted that the resilient arc-shaped strip 411 and the resilient arc-shaped strip 411 can be made of resilient metal materials, and of course, it is not limited to this one material.

[0065] Embodiment 4

[0066] Please refer to Figure 4 , the intermittent fixing part 43 includes: an arc-shaped guide rail 431, a connecting seat 432, a touch opening button 433, a touch closing button 434, and a limiting plate 435;

[0067] Among them, the arc-shaped guide rail 431 is fixed on the top of the support frame 42 and is placed below the two groups of resilient connecting strips 412. The top of the arc-shaped guide rail 431 has an arc-shaped groove, so that the two groups of resilient connecting strips 412 of the driving part 41 move along the arc-shaped groove, so that the forging die 1 rotates within the annular limiting convex edge 21. An arc-shaped slider adapted to it is slidably arranged at one end in the arc-shaped groove. The arc-shaped groove has a starting end and a ending end. In the initial state, the arc-shaped slider is placed at the starting end position in the arc-shaped groove;

[0068] The connecting seat 432 has a hollow structure inside and is fixedly arranged on the top of the arc-shaped slider. A support plate is arranged at the position between the connecting seat 432 and the driving part 41 on the top of the arc-shaped slider;

[0069] One end of the limiting plate 435 movably penetrates through the support plate and is inserted on one side of the connecting seat 432. The other end of the limiting plate 435 is clamped on the outside of the left resilient arc-shaped strip 411. At the same time, it can be seen from the appendix Figure 3 The limiting plate 435 is in an L shape. The bottoms of the two groups of resilient arc-shaped strips 411 are both attached to the inner wall of the bottom of the limiting plate 435. A convex block that fits the top of the right resilient arc-shaped strip 411 is also arranged on one side of the support plate to limit the right resilient arc-shaped strip 411. In actual situations, rubber layers are arranged on the inner wall of the limiting plate 435 and the outer wall of the convex block. Because during forging, the forging die 1 will generate vibrations, and the vibrations are transmitted to the driving part 41. Through the rubber layer, it can be avoided that the resilient connecting strips 412 in the driving part 41 come into hard contact with the limiting plate 435 and the convex block;

[0070] It should be noted that, although not shown in the drawings, one end of an elastic member is connected to the left bottom end of the limit plate 435 through an insert, and the other end of the elastic member is connected to the support plate. The elastic member may preferably adopt a spring structure to assist the limit plate 435 in moving and resetting.

[0071] Furthermore, a permanent magnet block (not shown in the figure) is embedded in one end of the limit plate 435 inserted in the connection seat 432, and an electromagnetic block (not shown in the figure) for adsorbing the permanent magnet block when powered is provided on the right inner wall of the connection seat 432. In a normal state, there is a certain distance between the electromagnetic block and the permanent magnet block. When the electromagnetic block is powered, the permanent magnet block is adsorbed, and then the tough connecting strip 412 on the left side is driven to move toward the tough connecting strip 412 on the right side through the limit plate 435, so that the tough arc strip 411 applies a certain pressure to the forging die 1;

[0072] The touch-on button 433 and the touch-off button 434 are both electrically connected to the electromagnetic block, and both ends of the arc-shaped slider are provided with touch blocks cooperating with the touch-on button 433 and the touch-off button 434, wherein the touch-on button 433 and the touch-off button 434 are respectively arranged on the inner walls on both sides of the arc-shaped groove. Specifically, the touch-on button 433 is arranged on the inner wall of the starting end of the arc-shaped groove, and the touch-off button 434 is arranged on the inner wall of the ending end of the arc-shaped groove.

[0073] Example 5

[0074] See also Figure 3-4 The driving part 44 includes: a cylinder 441, an elastic reset member 442, a connecting rope 443, an L-shaped frame 444, a contact gear 445, a driving device 446 and a toothless gear 447;

[0075] The cylinder 441 is arranged on the top of the support frame 42 and is placed inside the arc-shaped guide rail 431. The cylinder 441 is hollow inside, and a roller (not shown in the figure) is arranged inside the cylinder 441 to rotate through a rotating shaft. The bottom end of the rotating shaft passes through the bottom of the cylinder 441 and the support frame 42, and the top end of the rotating shaft passes through the top of the cylinder 441.

[0076] The elastic reset member 442 may be a torsion spring or a spring, and is used to drive the shaft to reset and rotate when the toothless gear 447 and the contact gear 445 are not in meshing state. The elastic reset member 442 is arranged at the connection between the top end of the shaft and the cylinder 441;

[0077] The connecting rope 443 has a movable end, which is connected to one end of the arc block away from the touch start button 433, and the other end passes through the rear end of the arc guide rail 431 and the side wall of the cylinder 441 and then is wound around the outer wall of the roller. The support frame 42 is provided with a guide wheel to guide the connecting rope 443 so that the arc block can move in the arc groove. The outer wall of the cylinder 441 is provided with a movable hole for the connecting rope 443 to pass through, and the rotating shaft drives the roller to rotate so that the roller reels the connecting rope 443.

[0078] It should be noted that the positions of the connecting rope 443 and the touch-off button 434 are staggered, and the end of the arc block close to the touch-on button 433 is also connected to the inner wall of the starting end of the arc groove through an arc elastic member (not shown in the figure). The arc elastic member is staggered with the touch-on button 433, and an arc spring structure can be preferably used. The connecting rope 443 pulls the arc block from the starting end to the end end in the arc groove until the arc block contacts the touch-off button 434, so that the touch-off button 434 controls the electromagnetic block to close. At this time, the two sets of tough connecting strips 412 are separated, and the tough arc strip 411 will not drive the forging die 1 to rotate;

[0079] An L-shaped frame 444 is provided at the bottom of the support frame 42 and serves as a support and mounting structure;

[0080] The contact gear 445 is fixedly sleeved on the bottom of the outer wall of the rotating shaft on the roller shaft;

[0081] A driving device 446, including a driving motor, is disposed at the bottom of the L-shaped frame 444, and an output end thereof penetrates the L-shaped frame 444 to drive the toothless gear 447 to rotate;

[0082] The toothless gear 447 is fixedly sleeved on the output end of the driving device 446 and meshed with the contact gear 445. The toothless gear 447 includes: a disc portion sleeved on the output end of the driving device 446 and an arc-shaped tooth segment arranged on the disc portion. The arc-shaped tooth segment has a starting end and an ending end. When the arc block is placed at the starting end in the arc groove, the contact gear 445 meshes with the starting end of the arc-shaped tooth segment. The driving device 446 drives the toothless gear 447, and the toothless gear 447 drives The contact gear 445 controls the rotating shaft to rotate the roller body to reel in the connecting rope 443. When the arc block moves to the end of the arc groove, the end of the arc tooth segment just disengages from the contact gear 445. Under the action of the elastic reset member 442, the roller shaft rotates in the opposite direction to release the connecting rope 443. The arc elastic member pulls the arc block from the end of the arc groove to the starting end of the arc groove, thereby realizing that the driving part 41 drives the forging die 1 to intermittently rotate within a certain range.

[0083] Example 6

[0084] See also Figure 3-4, the intermittent rotating assembly 4 further includes: an air guide portion 45;

[0085] The air guide part 45 includes: a hollow shell 451, an air inlet pipe 452, a flow divider 453, an air guide cylinder 454, an air guide nozzle 455 and a transmission shaft 456;

[0086] The hollow shell 451 is in the shape of a hollow cylinder and is fixed to the top of the support frame 42. The hollow shell 451 is provided with a pressurizing blade (not shown in the figure). The pressurizing blade is in the prior art and will not be described in detail here. The pressurizing blade allows the outside to enter the hollow shell 451 and then be discharged.

[0087] The transmission shaft 456 is movably inserted at the bottom of the hollow shell 451, and the booster blade is fixedly sleeved on the outer wall of the transmission shaft 456 and placed in one end of the hollow shell 451. The other end of the transmission shaft 456 also penetrates the support frame 42 and is rotatably connected to the L-shaped frame 444 through a bearing;

[0088] The transmission shaft 456 and the output end of the driving device 446 are connected by a sprocket transmission group, which includes two sets of sprockets and a set of chains. The two sets of sprockets are respectively sleeved on the outer wall of the transmission shaft 456 and the output end of the driving device 446, and the chain is sleeved on the two sets of sprockets for transmitting rotational force.

[0089] The air inlet pipe 452 is inserted into the outer wall of one side of the hollow shell 451, and has a one-way valve inside. When the booster blade rotates in the hollow shell 451, the outside air enters the hollow shell 451 from the air inlet pipe 452. The one-way valve allows only air to enter the air inlet pipe 452 without exhausting gas. At the same time, a filter structure can be set in the air inlet pipe 452 to filter the incoming air.

[0090] The air guide cylinder 454 is provided with two groups, which are detachably fixed to the two ends of the support frame 42, and the air guide cylinder 454 is hollow inside to play the role of flow diversion;

[0091] The shunt pipe 453 is arranged on the support frame 42 and is used to connect the two sets of gas guide cylinders 454. The shunt pipe 453 is also connected to the top of the hollow shell 451 through a branch pipe. The branch pipe is also provided with a one-way valve, which allows the gas in the hollow shell 451 to be discharged through the branch pipe and will not enter the hollow shell 451 through the branch pipe;

[0092] The air guide nozzle 455 is arranged on the top of the air guide cylinder 454 and is connected to the air guide cylinder 454. The air outlet end of the air guide nozzle 455 is placed above the outside of the forging die 1 and faces the top center position of the forging die 1, that is, the forming groove on the top of the forging die 1.

[0093] To sum up, the working principle of a half-axle forging processing device for new energy vehicles is as follows: when in use, the electrical components in the present application are connected to an external power supply through a wire, one end of the half-axle semi-finished product to be forged is heated in a heating furnace and then placed in a forming groove of a forging die 1, and the half-axle semi-finished product to be forged placed in the forming groove of the forging die 1 is forged by the forging part 3 reciprocating up and down. During forging, the driving device 446 is turned on, and the driving device 446 drives the toothed gear 447, and the toothed gear 447 drives the contact gear 445, so that the roller rotates and reels the connecting rope 443, pulling the arc block from the starting end of the arc groove to the end end. When the arc block moves, the driving part 41 drives the forging die 1 to rotate a certain angle through the intermittent fixing part 43 until the arc block contacts the touch closing button 434 at the end end of the arc groove. At this time, the electromagnetic block is closed, and the two sets of tough connecting strips 412 are separated. Under the action of the arc elastic member and the elastic reset member 442, the arc block is reset and moved from the end end of the arc groove. The arc block 410 moves to the starting end of the arc groove. During this process, the tough arc strip 411 will not drive the forging die 1 to rotate until the arc block contacts the touch start button 433 at the starting end of the arc groove. At this time, the electromagnetic block is turned on to move the limit plate 435. The limit plate 435 brings the two sets of tough connecting strips 412 closer, so that the tough arc strip 411 applies pressure to the forging die 1, so that the subsequent arc block moves from the starting end of the arc groove to the end end and drives the forging die 1 to rotate through the driving part 41, and so on and so forth. During forging, the forging die 1 is intermittently rotated to adjust the forging position of the half-shaft to be forged. At the same time, when the driving device 446 rotates, the transmission shaft 456 is also rotated through the sprocket transmission group. The transmission shaft 456 drives the boost fan blades to rotate in the hollow shell 451, and then the outside air enters the hollow shell 451 from the air intake pipe 452 and is then ejected from the air nozzle 455 through the branch pipe, the diverter pipe 453 and the air guide cylinder 454, so that the iron oxide shavings that fall into the forming groove of the forging die 1 are blown away from the forging die 1.

[0094] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
