Description

Technical Field

[0001] The invention relates to the technical field of metal processing, in particular to a square shaft part processing device. Background Art

[0002] Metal forging is a common metalworking process. Forging utilizes a forging machine to apply pressure to a metal blank, causing it to plastically deform in order to achieve a metal with specific mechanical properties, shape, and size. Square shaft forging is primarily used to manufacture various mechanical components. Square shafts are characterized by their square or rectangular cross-sections, which, compared to round shafts, offer a larger contact area and better torque transmission capabilities. Therefore, they are more common in applications requiring heavy loads or torque. In the free forging process, also known as dieless forging, workers often rely on manually operated clamps to control the flipping of the forging on the anvil, thereby controlling the forging angle and degree of deformation. Repeated forging ensures uniform forging of all parts of the forging, avoiding localized excessive or insufficient deformation during processing, ensuring the overall quality and performance of the forging, and better controlling the size and shape of the forging.

[0003] However, in the current free forging process, due to the large mass of some forging blanks, it is difficult for workers to operate the clamping pliers to flip the forgings. Repeated flipping of the forgings not only consumes the workers' physical strength to a great extent, but also easily leads to improper operation due to physical exhaustion, causing the forgings to roll off the anvil, posing a major safety hazard. Summary of the Invention

[0004] The purpose of the present invention is to provide a square shaft part processing device, which can reduce the difficulty of workers in turning over the forgings during the processing and forging of square shaft parts.

[0005] The technical solution of the present invention is:

[0006] A processing device for square shaft parts, including an anvil and a hydraulic forging system, further comprising: a clamping arm auxiliary member, the clamping arm auxiliary member including: a housing arranged behind the anvil through a frame; a driving shaft horizontally penetrating the housing and driven by an external driving force; two rocker arms arranged at both ends of the driving shaft, one end of each rocker arm is connected to the driving shaft, and the rocker arm is vertically arranged with respect to the driving shaft. A through hole is provided at the other end of each rocker arm along the thickness direction of the rocker arm. A connecting joint is provided in the through hole of each rocker arm. Each connecting joint includes: a rotating cylinder rotatably sleeved in the through hole, and a connecting rod is vertically arranged at one end of the rotating cylinder; two clamping arms, one end of each clamping arm is respectively connected to the two connecting rods, and the other end is a hand-held end with an anti-slip sleeve sleeved thereon. A top column is provided on the inner side of each of the two clamping arms. The top column is vertically arranged on the clamping arm, one end is connected to the clamping arm, and the other end is used to contact the forging. The end of the top column contacting the forging is a hemispherical surface. The clamping arms rotate around the connecting rod to adjust the included angle between the two clamping arms. The clamping arms rotate around the rotating cylinder to adjust the clamping position of the top column on the forging. The hand-held ends of the two clamping arms approach each other so that the two top columns abut against the surface of the forging. By using the swing of the rocker arm, while driving the clamping arms to carry the forging to move, the forging is turned over with the top column as the axis.

[0007] Further, each clamping arm includes: a first rod body, which is a straight rod structure; a second rod body, which is an arc-shaped rod. One end of the second rod body is connected to one end of the first rod body, and the other end is connected to the top column. The setting direction of the top column is consistent with the tangent direction of the arc at the other end of the second rod body. The other end of the first rod body is connected to the connecting rod; a third rod body, one end of which is connected to the outer arc surface at the position of the other end of the second rod body. The third rod body is a straight rod structure and is on the same line as the first rod body. The arc-shaped second rod body not only expands the clamping space at the position where the two clamping arms clamp the forging, avoiding the clamping arms from touching the edges of the forging when approaching, but also connects the top column to the end face of the other end of the second rod body and keeps it consistent with the tangent direction of the arc at the other end of the second rod body. When operating the two clamping arms to make the front ends of the two top columns tightly press against the forging, the clamping force applied to the clamping arms and the force received by the top column from the forging are both transmitted through the arc-shaped second rod body, making the clamping arms more stable when clamping the forging.

[0008] Further, a driving gear is sleeved on a section of the driving shaft located inside the housing. A first motor is provided above the housing, and a motor gear is configured on the output shaft of the first motor. Both the driving gear and the motor gear are bevel gears, and the driving gear and the motor gear are meshed through a gear set, making the driving of the driving shaft more convenient and controllable.

[0009] Furthermore, the top column is rotatably connected to the other end of the second rod body through a rotating member. A cavity is provided at the other end of the second rod body. The side surface of the cavity opposite to the end surface of the other end of the second rod body is called the installation wall of the cavity. The rotating member includes: a rotating disk provided on the installation wall; a connecting rod body, one end of which is connected to the center of the rotating disk, and the other end penetrates through the end surface of the other end of the second rod body and is connected to the top column. When the clamping arm is clamped, the top column abuts against the surface of the forging. When the forging is flipped, the top column rotates due to the frictional force caused by the clamping force, so that the forging can be flipped more smoothly.

[0010] Furthermore, the connecting rod body includes: an outer sleeve, one end of which penetrates through the end surface of the other end of the second rod body and is connected to the top column. A spring is sleeved inside the outer sleeve, and a chute is provided along the length direction of the inner side wall of the outer sleeve; an inner sleeve rod, one end of which is connected to the rotating disk, and the other end is sleeved inside the outer sleeve and abuts against the spring. A limiting slider is provided on the circumferential side of the rod body of the inner sleeve rod, and the limiting slider is slidably arranged in the chute. By sliding the limiting slider in the chute, not only can the outer sleeve be restricted to slide only along the length direction of the inner sleeve rod, but when the top column rotates, the inner sleeve rod and the outer sleeve rotate synchronously through the cooperation of the limiting slider and the chute.

[0011] Furthermore, the frame body has two vertical rods, and a transmission screw rod assembly is provided between the two vertical rods. The housing is arranged on the slider of the transmission screw rod assembly. The transmission screw rod assembly is started to make the slider drive the housing to displace. A third motor is externally connected to the screw rod of the transmission screw rod assembly. Through the transmission screw rod assembly, the position adjustment of the forging in the left-right direction on the anvil can be completed. By using the connection relationship between the clamping arm and the rocker arm, while clamping the forging and moving it left and right, the clamping arm is pushed and pulled back and forth, and the adjustment of the forging in the front-back direction on the anvil can be completed. Through the cooperation of the transmission screw rod assembly and the rocker arm, the forging can be adjusted back to the center position of the anvil.

[0012] Furthermore, the slider is of a hollow structure, and a second motor is provided inside. The output shaft of the second motor penetrates through the slider and is connected to the housing through a connecting block. The connecting block is disc-shaped, the housing is cylindrical, the central axis of the driving shaft coincides with the connecting line of the center points of the two circular surfaces of the housing. The connecting block is connected to the arc surface of the housing close to the slider, and the center of the connecting block is connected to the center position of the arc surface. The output shaft of the second motor is connected to a position deviating from the center of the circle of the connecting block. Through the rotation of the output shaft of the second motor and the eccentric setting of the output shaft and the connecting block, the connecting block maintains an elliptical movement track. Compared with a circular movement track, it is easier to flip the forging to the left and right.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. In the present invention, the ejector pins on the inner sides of the two clamping arms are respectively abutted against two opposite sides of the forging, and a clamping arm auxiliary member for assisting workers to flip the forging is arranged at the other end of the clamping arm. When flipping the forging by clamping it, the hand-held ends of the two clamping arms approach each other, so that the two ejector pins abut against the surface of the forging. The first motor is started to rotate the drive shaft, swing the rocker arm, and at the same time the worker operates the clamping arm to perform the flipping action of the forging. The rocker arm swings around the drive shaft, cooperating with the manual operation of the worker, enabling the clamping arm to carry the forging to move while flipping the forging around the ejector pin to complete the turning over in a predetermined direction. The worker only needs to operate the clamping arm to perform the basic flipping action, while the rocker arm provides the main power output required for flipping the forging. The two cooperate with each other, greatly reducing the difficulty for the worker to flip the forging, so that the square shaft rough blank with a larger mass and a larger volume can be forged by the way of manual free forging, and at the same time, the processing and forging efficiency of the square shaft parts can be improved.

[0015] 2. After the clamping arm of the present invention clamps the forging, the housing arranged on the slider is displaced through the transmission screw rod assembly, so as to adjust the position of the forging on the anvil. And due to the connection relationship between the clamping arm and the rocker arm, when the forging is clamped and moved left and right, the clamping arm is pushed and pulled back and forth, and the adjustment of the forging in the front and back directions on the anvil can be completed. Through the cooperation of the transmission screw rod assembly and the rocker arm, the forging can be adjusted back to the center position of the anvil, avoiding the problem that the forging deviates from the center of the anvil due to continuous flipping of the forging, resulting in uneven distribution of the hammering force on the forging and inconsistent deformation degrees of each part of the forging, and ensuring the shape and dimensional accuracy of the forging.

[0016] 3. In the present invention, a second motor is arranged in the slider. Due to the eccentric setting of the output shaft of the second motor and the connecting block on the housing, when the output shaft of the second motor rotates, the connecting block maintains an elliptical movement trajectory. Compared with the circular movement trajectory, it is easier to flip the forging to the left and right.

[0017] 4. The first motor, the second motor and the third motor of the present invention are all equipped with controllers, and each controller is equipped with a remote control. The remote control is arranged at the hand-held end of the clamping arm, which is more convenient for the worker to drive the corresponding motor to assist in completing the corresponding action when flipping the forging.

[0034] Embodiment

[0035] A processing device for square shaft parts includes an anvil 9 and a hydraulic forging system. Both the anvil 9 and the hydraulic forging system are commercially available products and will not be elaborated here. As Figure 1 and Figure 3 shown, the forging processing device of this embodiment further includes: a clamping arm auxiliary and two clamping arms 5. As Figure 1 shown, the clamping arm auxiliary includes: a housing 1, a drive shaft 2, and two rocker arms 3. As Figure 3 and Figure 4 shown, the housing 1 is arranged behind the anvil 9 through a frame 10; the drive shaft 2 horizontally penetrates through the housing 1 and is externally connected to a driving force for driving; the two rocker arms 3 are arranged at both ends of the drive shaft 2. One end of each rocker arm 3 is connected to the drive shaft 2, and the rocker arm 3 is perpendicularly arranged to the drive shaft 2. A through hole 31 is opened at the other end of each rocker arm 3 along the thickness direction of the rocker arm 3. A connecting joint 4 is arranged in the through hole 31 of each rocker arm 3. As Figure 5 and Figure 7 shown, each connecting joint 4 includes a rotating cylinder 41 and a connecting rod 44. The rotating cylinder 41 is rotatably sleeved in the through hole 31. An installation groove 42 is vertically arranged at one end of the rotating cylinder 41, and the connecting rod 44 is installed in the installation groove 42. Both ends of the connecting rod 44 are rotatably connected to the groove wall of the installation groove 42, and a sphere 43 is sleeved on the middle section of the connecting rod 44. As Figure 3 and Figure 5 shown, one ends of the two clamping arms 5 are respectively connected to the two spheres 43, and the other ends are hand-held ends, and anti-slip sleeves are sleeved on the hand-held ends.Figure 3 As shown, on the inner sides of both clamping arms 5, there are top columns 53 vertically arranged on the clamping arms 5. One end is connected to the clamping arm 5, and the other end is used to contact the forging 8. The end of the top column 53 contacting the forging 8 is a hemispherical surface. The clamping arms 5 rotate around the connecting rod 44 to adjust the included angle between the two clamping arms 5. The clamping arms 5 rotate around the rotating cylinder 41 to adjust the clamping position of the top column 53 on the forging 8; As Figure 3 shown, the hand-held ends of the two clamping arms 5 are close to each other, so that the two top columns 53 abut against the surface of the forging 8, and the forging 8 is tightened between the two top columns 53. At this time, start the external driving force to make the driving shaft 2 rotate. The driving shaft 2 swings the rocker arm 3. Using the movement track of the rocker arm 3 swinging around the driving shaft 2, while the driving clamping arm 5 carries the forging 8 to move, the forging 8 is turned over around the top column 53, thus assisting the worker to turn over the forging 8 and reducing the difficulty for the worker to flip the forging 8.

[0036] As Figure 3 shown, each clamping arm 5 includes: a first rod body 51, a second rod body 52 and a third rod body 54. Among them, both the first rod body 51 and the third rod body 54 are straight rod structures; the second rod body 52 is an arc-shaped rod. As Figure 3 shown, the inner arc surfaces of the two second rod bodies 52 are arranged opposite to each other. One end of the second rod body 52 is connected to one end of the first rod body 51, and the other end is connected to the top column 53. The setting direction of the top column 53 is consistent with the arc tangent direction of the other end of the second rod body 52, so as to ensure that when the two clamping arms 5 approach each other, the top column 53 can tightly abut against and clamp the forging 8; The other end of the first rod body 51 is connected to the sphere 43 on the connecting rod 44. One end of the third rod body 54 is connected to the outer arc surface of the other end of the second rod body 52 and is on the same line as the first rod body 51. The arc-shaped second rod body 52 not only expands the clamping space at the position where the two clamping arms 5 clamp the forging 8, avoiding the clamping arms 5 touching the edges of the forging 8 when approaching, but also connects the top column 53 to the end surface of the other end of the second rod body 52 and keeps it consistent with the arc tangent direction of the other end of the second rod body 52. When operating the two clamping arms 5 to make the front ends of the two top columns 53 tightly abut against the forging 8, the clamping force applied to the clamping arms 5 and the force received by the top column 53 from the forging 8 are both transmitted through the arc-shaped second rod body 52, making the clamping arms 5 more stable when clamping the forging 8.

[0037] As Figure 1 shown, in order to facilitate the driving control of the driving shaft 2, a driving gear 21 is sleeved on a section of the driving shaft 2 located inside the housing 1. A first motor 32 is provided above the housing 1. A motor gear is arranged on the output shaft of the first motor 32. Both the driving gear 21 and the motor gear are bevel gears. The driving gear 21 and the motor gear are meshed through a gear set. As Figure 1As shown, the gear set is specifically a transmission bevel gear arranged between the motor gear and the driving gear 21.

[0038] In some embodiments, in order to avoid the problem that the friction force between the ejector pin 53 and the forging 8 increases due to the clamping force, resulting in the forging 8 not being smoothly flipped, as Figure 6 shown, the ejector pin 53 and the other end of the second rod body 52 are rotatably connected through a rotating member. A cavity is provided at the other end of the second rod body 52. The side surface of the cavity opposite to the end surface of the other end of the second rod body 52 is called the mounting wall 55 of the cavity. Specifically, the rotating member includes: a rotating disk 56 and a connecting rod body. The rotating disk 56 is arranged on the mounting wall 55 and rotates around its own center; one end of the connecting rod body is connected to the center of the rotating disk 56 and is perpendicular to the rotating disk 56. The other end of the connecting rod body penetrates through the end surface of the other end of the second rod body 52 and is connected to the ejector pin 53. When the ejector pin 53 abuts against the surface of the forging 8 and the forging 8 is flipped, the friction force caused by the clamping force makes the ejector pin 53 rotate, so that the forging 8 can be more smoothly flipped.

[0039] In some embodiments, in order to have a certain buffering effect on the forging 8 when the clamping arms 5 approach each other, as Figure 6 shown, the connecting rod body includes: an outer sleeve 58 and an inner sleeve rod 57. One end of the outer sleeve 58 penetrates through the end surface of the other end of the second rod body 52 and is connected to the ejector pin 53. A spring 59 is sleeved inside the outer sleeve 58, and sliding grooves are formed along the length direction of the inner side wall of the outer sleeve 58, for example, four sliding grooves; one end of the inner sleeve rod 57 is connected to the rotating disk 56, and the other end is sleeved inside the outer sleeve 58 and abuts against the spring 59. A limiting slider 571 is provided on the circumferential side of the rod body of the inner sleeve rod 57. The number of the limiting sliders 571 corresponds to the number of the sliding grooves, and each limiting slider 571 slides in the sliding groove at the corresponding position. By the limiting slider 571 sliding in the sliding groove, not only can the outer sleeve 58 be restricted to slide only along the length direction of the inner sleeve rod 57, but when the ejector pin 53 rotates, the inner sleeve rod 57 and the outer sleeve 58 rotate synchronously through the cooperation of the limiting slider 571 and the sliding groove.

[0040] As Figure 1 and Figure 2 shown, due to continuously flipping the forging 8, it is easy to cause the position of the forging 8 on the anvil 9 to change, making the forging 8 deviate from the center of the anvil 9, resulting in uneven distribution of the hammering force exerted by the hydraulic forging system on the forging 8, and thus the deformation degrees of various parts of the forging 8 are inconsistent, affecting the shape and dimensional accuracy of the forging 8. In order to adjust the position of the forging 8 on the anvil 9, the frame body 10 has two vertical rods, and a transmission screw rod assembly 6 is arranged between the two vertical rods. The housing 1 is arranged on the slider 61 of the transmission screw rod assembly 6. A third motor is externally connected to the screw rod of the transmission screw rod assembly 6. The transmission screw rod assembly 6 is started to make the slider 61 drive the housing 1 to displace, asFigure 3 As shown, through the transmission screw rod assembly 6, the position adjustment of the forging 8 in the left and right directions of the anvil 9 can be completed. By using the connection relationship between the clamping arm 5 and the rocker arm 3, while the forging 8 is clamped and moved left and right, the clamping arm 5 is pushed and pulled back and forth, and the adjustment of the forging 8 in the front and back directions of the anvil 9 can be completed. Through the cooperation of the transmission screw rod assembly 6 and the rocker arm 3, the forging 8 can be adjusted back to the central position of the anvil 9.

[0041] As Figure 2 , Figure 3 and Figure 4 As shown, the slider 61 is of a hollow structure, and a second motor 7 is arranged inside. The output shaft of the second motor 7 penetrates out of the slider 61 and is connected to the housing 1 through the connecting block 11. The connecting block 11 is disc-shaped, the housing 1 is cylindrical, the central axis of the driving shaft 2 coincides with the connecting line of the center points of the two circular surfaces of the housing 1. The connecting block 11 is connected to the arc surface of the housing 1 close to the slider 61, and the center of the connecting block 11 is connected to the center position of the arc surface. The output shaft of the second motor 7 is connected to a position deviating from the center of the circle of the connecting block 11. Through the rotation of the output shaft of the second motor 7 and the eccentric setting of the output shaft and the connecting block 11, the connecting block 11 maintains an elliptical movement trajectory. Compared with the circular movement trajectory, it is easier to turn the forging 8 to the left and right.

[0042] In order to facilitate the driving of the first motor 32, the second motor 7 and the third motor, controllers are arranged on the first motor 32, the second motor 7 and the third motor respectively, and a remote controller for remotely controlling the corresponding motor is arranged at the handheld end of the clamping arm 5. Signals are sent from the remote controller to the corresponding controller, and after receiving the signals, this controller drives its corresponding motor to work. It should be noted that the motors equipped with controllers can be purchased on the market, and the purchased motors are all equipped with remote controllers and operation manuals.

[0043] Application Example 1

[0044] As Figure 8 shown, the six surfaces of the forging 8 are surface a, surface b, surface c, surface d, surface e and surface f respectively.

[0045] When Figure 8 shown forging 8 is turned in the front and back directions, as Figure 9 shown, at this time, surface a is facing up. It is necessary to turn the forging 8 so that surface b is facing up. First, operate the clamping arm 5 to clamp the forging 8, so that the two ejector pins 53 are respectively abutted against the surface e and surface f of the forging 8, as Figure 9 shown. In order to turn the forging 8 more easily, the ejector pins 53 are abutted against the lower right corners of the surface e and surface f. Then start the first motor 32 to drive the driving shaft 2 to rotate, and at the same time the worker starts to operate the clamping arm 5 to perform a turning action on the forging 8. The direction of the turning action is as Figure 9As shown by the arrow direction, through the swing of the rocker arm 3 in coordination with the flipping action of the worker, the forging 8 is quickly flipped in the front-back direction.

[0046] Application Example 2

[0047] When flipping the forging 8 shown in Figure 8 in the left-right direction, as shown in Figure 10 、 Figure 11 and Figure 12 shown, at this time, the a surface is facing up, and it is necessary to flip the forging 8 so that the f surface is facing up. First, as shown in Figure 10 shown, the clamping arm 5 clamps the forging 8, and the forging 8 is moved to the left of the anvil 9 by the transmission screw assembly 6 to the position shown in Figure 10 This is to prevent the flipped forging 8 from pressing on the clamping arm 5. Then, start the second motor 7 to make the housing 1 rotate eccentrically. At the same time, the worker starts to operate the clamping arm 5 to perform a leftward flipping action on the forging 8. The direction of the flipping action is as shown by the arrow direction in Figure 10 . Through the torsion of the housing 1 itself and the manual operation of the worker, the forging 8 is flipped to the state shown in Figure 11 . At this time, the f surface is already facing up. It should be noted that when performing this operation, the left clamping arm 5 can be lowered through the rotating cylinder 41, and the right clamping arm 5 can be raised through the rotating cylinder 41, so as to make it easier to flip the forging 8 to the left. Finally, as shown in Figure 12 shown, the clamping arm 5 clamps on the a surface and the c surface, and the forging 8 is reset to the center position of the anvil 9 through the transmission screw assembly 6.

[0048] The above discloses only several preferred specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any changes that can be thought of by those skilled in the art should fall within the protection scope of the present invention.
