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 metal processing technology. Forging is a metal processing method that uses forging machinery to apply pressure to metal blanks to cause plastic deformation in order to obtain metal processing methods with certain mechanical properties, certain shapes and sizes. Square shaft forging is mainly used to manufacture various mechanical parts. Square shaft parts are characterized by square or rectangular cross-sections. Compared with round shafts, they have larger contact areas and better torque transmission capabilities. Therefore, they are more common in some occasions that require large loads or large torque transmission. In the free forging of square shaft parts, that is, dieless forging, workers often need to manually operate the clamps to control the flipping of the forging on the anvil, thereby controlling the angle of the forging and the degree of deformation. After repeated flipping and forging, it is ensured that all parts of the forging are evenly forged, avoiding local excessive deformation 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 turning over the forgings during the processing and forging of square shaft parts.

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

[0006] A square shaft parts processing device includes an anvil and a hydraulic forging system, and also includes: a clamping arm auxiliary part, the clamping arm auxiliary part includes: a shell, which is arranged behind the anvil through a frame; a drive shaft, which horizontally penetrates the shell and is driven by an external drive force; two rocker arms, which are arranged at both ends of the drive shaft, one end of each of the rocker arms is connected to the drive shaft, and the rocker arm and the drive shaft are arranged vertically, and the other end of the rocker arm has a through hole along the thickness direction of the rocker arm, and each through hole of the rocker arm is provided with a connecting joint, and each connecting joint includes: a rotating cylinder, which is 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 which is connected to the drive shaft They are respectively connected to two connecting rods, and the other end is a hand-held end, and an anti-slip sleeve is mounted on the hand-held end. A top column is provided on the inner side 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 in contact with the forging is a hemispherical surface. The clamping arm rotates with the connecting rod as the axis to adjust the angle between the two clamping arms. The clamping arm uses the rotating cylinder as the axis to adjust the clamping position of the top column on the forging; the hand-held ends of the two clamping arms are close to each other so that the two top columns abut against the surface of the forging, and the swing of the rocker arm is used to drive the clamping arm to carry the forging to move, and at the same time, the forging is turned over with the top column as the axis.

[0007] Furthermore, each of the clamping arms comprises: 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 arc tangent direction of the other end of the second rod body, and 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 other end of the second rod body, the second rod body is a straight rod structure, and is on the same connecting line as the first rod body. The second rod body with an arc structure not only expands the clamping space at the position where the two clamping arms clamp the forging, and avoids the clamping arms touching the edges of the forging when approaching, but also connects the top column to the end surface of the other end of the second rod body and keeps it consistent with the arc tangent direction of the other end of the second rod body. When the two clamping arms are operated to make the front ends of the two top columns press against the forging, the clamping force applied to the clamping arms and the force applied to the top column from the forging are transmitted through the arc-shaped second rod body, so that the clamping arms are more stable when clamping the forging.

[0008] Furthermore, a driving gear is sleeved on a section of the driving shaft located inside the shell, a first motor is provided above the shell, a motor gear is configured on the output shaft of the first motor, the driving gear and the motor gear are both 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, and a cavity is provided at the other end of the second rod body, and a side surface of the cavity arranged opposite to the end face of the other end of the second rod body is called a mounting wall of the cavity, and the rotating member includes: a rotating disk, which is arranged on the mounting wall; a connecting rod body, one end of which is connected to the center of the rotating disk, and the other end passes through the end face 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 friction force caused by the clamping force causes the top column to rotate, thereby allowing the forging to complete the flipping more smoothly.

[0010] Furthermore, the connecting rod body includes: an outer sleeve, one end of which passes 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 slide groove is provided on the inner wall of the outer sleeve along its length direction; an inner 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 circumference of the rod body of the inner rod, and the limiting slider is slidably set in the slide groove, and the limiting slider slides in the slide groove, which not only limits the outer sleeve to slide only along the length direction of the inner rod, but also, when the top column rotates, the inner rod and the outer sleeve rotate synchronously through the cooperation of the limiting slider and the slide groove.

[0011] Furthermore, the frame has two vertical rods, and a transmission screw assembly is provided between the two vertical rods. The housing is provided on a slider of the transmission screw assembly, and the transmission screw assembly is started so that the slider drives the housing to move. A third motor is externally connected to the screw of the transmission screw assembly, and the position adjustment of the forging in the left and right directions of the anvil can be completed through the transmission screw assembly. By utilizing the connection relationship between the clamping arm and the rocker arm, while the forging is clamped and moved left and right, the clamping arm is pushed and pulled forward and backward to complete the adjustment of the forging in the front and rear directions of the anvil. Through the cooperation of the transmission screw assembly and the rocker arm, the forging can be adjusted back to the center position of the anvil.

[0012] Furthermore, the slider is a hollow structure with a second motor inside. The output shaft of the second motor passes through the slider and is connected to the shell through a connecting block. The connecting block is disc-shaped and the shell is cylindrical. The central axis of the drive shaft coincides with a line connecting the center points of the two circular surfaces of the shell. The connecting block is connected to an arc-shaped surface of the shell close to the slider, and the center of the connecting block is connected to the center position of the arc-shaped surface. The output shaft of the second motor is connected to a position of the connecting block that deviates from the center of the circle. 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 motion trajectory, which makes it easier to flip the forging left or right compared to a circular motion trajectory.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The present invention has two inner top columns of the two clamping arms abutted against two opposite side surfaces of the forging, and a clamping arm auxiliary part for assisting the worker to flip the forging is arranged at the other end of the clamping arm. When the clamping forging is flipped, the hand-held ends of the two clamping arms are close to each other so that the two top columns abut against the surface of the forging, the first motor is started to rotate the drive shaft, the rocker arm is swung, and the worker operates the clamping arm to flip the forging. The rocker arm swings with the drive shaft as the axis, and the worker's manual operation is coordinated so that the clamping arm, under the electric support of the rocker arm, carries the forging to move while the forging is turned over with the top column as the axis in a predetermined direction. The worker only needs to operate the clamping arm to perform basic flipping actions, and the rocker arm provides the main power output required for flipping the forging. The two cooperate with each other to greatly reduce the difficulty of the worker in flipping the forging, so that a square shaft blank with a larger mass and a larger volume can be forged by manual free forging, and the efficiency of processing and forging square shaft parts can be improved.

[0015] 2. After the clamping arm of the present invention clamps the forging, the shell set on the slider is displaced through the transmission screw assembly, so as to adjust the position of the forging on the anvil. Due to the connection relationship between the clamping arm and the rocker arm, while the clamping forging is moved left and right, the clamping arm is pushed and pulled forward and backward to complete the adjustment of the forging in the front and rear directions of the anvil. Through the cooperation of the transmission screw assembly and the rocker arm, the forging can be adjusted back to the center position of the anvil, avoiding the problem of uneven distribution of the hammer force on the forging and inconsistent deformation of various parts of the forging due to continuous flipping of the forging, which causes the forging to deviate from the center of the anvil. This ensures the shape and dimensional accuracy of the forging.

[0016] 3. The present invention provides a second motor in the slider. Through the eccentric setting of the output shaft of the second motor and the connecting block on the shell, the output shaft of the second motor can make the connecting block maintain an elliptical motion trajectory when rotating, which makes it easier to flip the forging to the left or right compared to a circular motion trajectory.

[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 controller. The remote controller is arranged at the handheld end of the clamping arm, which makes it more convenient for workers to drive the corresponding motors to assist them in completing the corresponding actions when flipping the forgings.

[0034] Example

[0035] A square shaft parts processing device includes an anvil 9 and a hydraulic forging system. The anvil 9 and the hydraulic forging system are both commercially available products and will not be described in detail herein. Figure 1 and Figure 3 As shown, the forging processing device of this embodiment also includes: a clamping arm auxiliary part and two clamping arms 5, such as Figure 1 As shown, the clamping arm auxiliary component includes: a housing 1, a drive shaft 2 and two rocker arms 3, as shown in FIG. Figure 3 and Figure 4 As shown, the housing 1 is arranged behind the anvil 9 through the frame 10; the drive shaft 2 horizontally penetrates the housing 1, and the drive shaft 2 is driven by an external driving force; 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 vertically arranged to the drive shaft 2, and the other end of the rocker arm 3 is provided with a through hole 31 along the thickness direction of the rocker arm 3, and each rocker arm 3 is provided with a connecting joint 4 in the through hole 31, as shown in FIG. Figure 5 and Figure 7 As 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. A mounting groove 42 is vertically provided at one end of the rotating cylinder 41. The mounting groove 42 is used to install the connecting rod 44. Both ends of the connecting rod 44 are rotatably connected to the groove wall of the mounting groove 42, and a ball 43 is sleeved in the middle section of the connecting rod 44. Figure 3 and Figure 5 As shown, one end of the two clamping arms 5 is connected to the two spheres 43 respectively, and the other end is a hand-held end, and an anti-slip sleeve is provided on the hand-held end, as shown in FIG. Figure 3 As shown, the inner sides of the two clamping arms 5 are provided with a top column 53, which is vertically arranged on the clamping arm 5, one end of which 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 that contacts the forging 8 is a hemispherical surface, and the clamping arm 5 rotates with the connecting rod 44 as an axis to adjust the angle between the two clamping arms 5. The clamping arm 5 uses the rotating cylinder 41 as an axis to adjust the clamping position of the top column 53 on the forging 8; Figure 3 As 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, so that the forging 8 is tightened between the two top columns 53. At this time, the external driving force is started to rotate the driving shaft 2, and the driving shaft 2 swings the rocker arm 3. The rocker arm 3 swings with the driving shaft 2 as the axis, so that the driving clamping arm 5 carries the forging 8 to move and the forging 8 is turned over with the top column 53 as the axis, thereby assisting the worker to turn over the forging 8 and reducing the difficulty of the worker to flip the forging 8.

[0036] like Figure 3 As shown, each clamping arm 5 comprises: a first rod body 51, a second rod body 52 and a third rod body 54, wherein the first rod body 51 and the third rod body 54 are both straight rod structures; the second rod body 52 is an arc rod, as shown in FIG. Figure 3 As 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 tangent direction of the arc line of the other end of the second rod body 52, so as to ensure that when the two clamping arms 5 are close to each other, the top column 53 can tightly press against the clamping forging 8; the other end of the first rod body 51 is connected to the ball 43 on the connecting rod 44, and 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, through the arc structure The second rod body 52 not only expands the clamping space at the position where the two clamping arms 5 clamp the forging 8, preventing the clamping arms 5 from touching the edges of the forging 8 when approaching, but also connects the top column 53 to the end face of the other end of the second rod body 52 and maintains the same direction as the arc tangent of the other end of the second rod body 52. ​​When the two clamping arms 5 are operated to make the front ends of the two top columns 53 press against the forging 8, the clamping force applied to the clamping arms 5 and the force applied to the top column 53 from the forging 8 are transmitted through the arc-shaped second rod body 52, so that the clamping arms 5 are more stable when clamping the forging 8.

[0037] like Figure 1 As 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, and a first motor 32 is provided above the housing 1. A motor gear is configured on the output shaft of the first motor 32. Both the driving gear 21 and the motor gear are bevel gears, and the driving gear 21 and the motor gear are meshed through a gear set, as shown in FIG. 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 forging 8 is not smoothly turned over due to the increase of friction between the top column 53 and the forging 8 caused by the clamping force, as shown in FIG. Figure 6 As shown, the top column 53 is rotatably connected to the other end of the second rod body 52 through a rotating member, and a cavity is provided at the other end of the second rod body 52. ​​The side surface of the cavity arranged opposite to the end face 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 the rotating disk 56 rotates around its own center as the axis; one end of the connecting rod body is connected to the center of the rotating disk 56 and remains perpendicular to the rotating disk 56. The other end of the connecting rod body passes through the end face of the other end of the second rod body 52 and is connected to the top column 53. When the top column 53 abuts against the surface of the forging 8, when the forging 8 flips, the friction force caused by the clamping force causes the top column 53 to rotate, thereby making the forging 8 flip more smoothly.

[0039] In some embodiments, in order to provide a certain buffering effect on the forging 8 when the clamping arms 5 are close to each other, as shown in FIG. Figure 6 As shown, the connecting rod body includes: an outer sleeve 58 and an inner sleeve rod 57, one end of the outer sleeve 58 passes through the end surface of the other end of the second rod body 52 and is connected to the top column 53, a spring 59 is sleeved inside the outer sleeve 58, and the inner wall of the outer sleeve 58 is provided with a slide groove along its length direction, for example, four slide 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 circumference of the rod body of the inner sleeve rod 57, the number of limiting sliders 571 corresponds to the number of slide grooves, and each limiting slider 571 slides in the slide groove at the corresponding position, and the limiting slider 571 slides in the slide groove, which not only limits the outer sleeve 58 to slide only along the length direction of the inner sleeve rod 57, but also when the top column 53 rotates, the inner sleeve rod 57 and the outer sleeve 58 rotate synchronously through the cooperation of the limiting slider 571 and the slide groove.

[0040] like Figure 1 and Figure 2 As shown, due to the continuous flipping of the forging 8, the position of the forging 8 on the anvil 9 is easily changed, causing the forging 8 to deviate from the center of the anvil 9, resulting in uneven distribution of the hammer force applied by the hydraulic forging system on the forging 8, thereby causing the deformation degree of each part of the forging 8 to be 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 10 has two vertical rods, and a transmission screw assembly 6 is provided between the two vertical rods. The housing 1 is arranged on a slider 61 of the transmission screw assembly 6, and a third motor is externally connected to the screw of the transmission screw assembly 6. The transmission screw assembly 6 is started so that the slider 61 drives the housing 1 to move, as shown in FIG. Figure 3 As shown, the position of the forging 8 in the left and right directions of the anvil 9 can be adjusted by the transmission screw assembly 6. By utilizing the connection relationship between the clamping arm 5 and the rocker arm 3, the clamping arm 5 can be pushed and pulled forward and backward while the clamping forging 8 is moved left and right, so that the forging 8 in the front and back directions of the anvil 9 can be adjusted. Through the cooperation of the transmission screw assembly 6 and the rocker arm 3, the forging 8 can be adjusted back to the center position of the anvil 9.

[0041] like Figure 2 , Figure 3 and Figure 4 As shown, the slider 61 is a hollow structure with a second motor 7 inside. The output shaft of the second motor 7 passes through the slider 61 and is connected to the shell 1 through a connecting block 11. The connecting block 11 is disc-shaped and the shell 1 is cylindrical. The central axis of the drive shaft 2 coincides with the line connecting the center points of the two circular surfaces of the shell 1. The connecting block 11 is connected to the arc surface of the shell 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 the position of the connecting block 11 that deviates from the center of the circle. 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 motion trajectory, which makes it easier to flip the forging 8 left and right compared to a circular motion trajectory.

[0042] In order to facilitate the driving of the first motor 32, the second motor 7 and the third motor, controllers are configured on the first motor 32, the second motor 7 and the third motor, and a remote controller for remotely controlling the corresponding motors is provided at the handheld end of the clamping arm 5. A signal is sent to the corresponding controller through the remote controller, and the controller drives the corresponding motor to work after receiving the signal. It is worth mentioning that motors equipped with controllers can be purchased on the market, and the purchased motors are equipped with remote controls and instructions for use.

[0043] Application Example 1

[0044] like Figure 8 As shown, the six faces of the forging 8 are face a, face b, face c, face d, face e and face f.

[0045] When Figure 8 When the forging 8 shown in the figure is turned over in the front-back direction, Fig. 9 As shown, at this time, the a surface is facing upwards, and the forging 8 needs to be turned over so that the b surface is facing upwards. First, the clamping arm 5 is operated to clamp the forging 8 so that the two top columns 53 are respectively in contact with the e surface and the f surface of the forging 8, as shown in FIG. Fig. 9 As shown, in order to more easily flip the forging 8, the top column 53 abuts against the lower right corner of the e surface and the f surface, and then the first motor 32 is started to drive the drive shaft 2 to rotate. At the same time, the worker starts to operate the clamping arm 5 to flip the forging 8. The direction of the flipping action is as shown in FIG. Fig. 9As shown in the direction of the arrow, the forging 8 is quickly flipped in the front-to-back direction by the swing of the rocker arm 3 and the flipping action of the worker.

[0046] Application Example 2

[0047] When Figure 8 When the forging 8 shown is turned over in the left and right directions, Fig.10 , Fig.11 and Fig.12 As shown, at this time, the a side faces upward, and the forging 8 needs to be turned over so that the f side faces upward. First, as shown in Fig.10 As shown, the clamping arm 5 clamps the forging 8 and moves the forging 8 to the left of the anvil 9 through the drive screw assembly 6. Fig.10 The position shown in the figure is to prevent the forged piece 8 from pressing the clamping arm 5 after the flipping. Then the second motor 7 is started to make the housing 1 rotate eccentrically. At the same time, the worker starts to operate the clamping arm 5 to flip the forged piece 8 to the left. The direction of the flipping action is as shown in the figure. Fig.10 As shown in the direction of the arrow, the forging 8 is turned over to the position shown in FIG. Fig.11 In the state shown in FIG. 1 , the f side is facing upward. It is worth noting that when performing this operation, the left clamping arm 5 can be lowered by the rotating drum 41, and the right clamping arm 5 can be raised by the rotating drum 41, so that the forging 8 can be turned to the left more easily. Fig.12 As shown, the clamping arm 5 is clamped 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 disclosures are only several preferred specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
