Description

Technical Field

[0001] The invention belongs to the technical field of forging machines, in particular to an automatic forging machine for metal parts. Background Art

[0002] A forging machine is a mechanical equipment used for processing metal materials. It is mainly used to plastically deform metal materials by applying pressure to obtain forgings with certain mechanical properties, shapes and sizes. It mainly includes flat forging machines, rotary forging machines and radial forging machines, etc. When facing the processing of rod-shaped or tubular workpieces, radial forging machines are often required for processing.

[0003] The prior art also proposes some solutions. For example, a patent application with publication number CN111167989A discloses a horizontal radial forging machine, including a frame, a forging box, a radial feed mechanism, a transmission box and an auxiliary mechanism; the frame includes a base and a support arm, and the support arm is provided with a first pin shaft; the transmission box is rotatably connected to the support arm through the first pin shaft, and has a unified power input. Compared with the four motor drives, the unified power input has higher accuracy, stronger stability, better synchronization, and higher forging accuracy; this structural form of the frame can have great strength and rigidity, can withstand great forging force, and thus can successfully forge large shaft parts.

[0004] During the continuous forging process of the workpiece by the radial forging machine in the prior art, the length of the workpiece will gradually increase. When one end of the workpiece is completely sent to the forging box, the workpiece is only supported by the clamp at one end and the forging box at the other end, and the middle part of the workpiece is in a suspended state, which causes the middle part of the longer workpiece to be easily bent. At the same time, since one end of the workpiece is only fixed by a clamp, and the other end is supported by the hammer head located at the bottom inside the forging box, this causes the workpiece to tilt, thereby reducing the accuracy of the workpiece processing.

DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] like Figures 1 to 4 As shown, an automatic forging machine for metal parts according to an embodiment of the present invention comprises a base 1; both ends of the top surface of the base 1 are slidably connected with a moving seat 2, and the moving seat 2 is driven by a servo motor; a clamping assembly is installed at one end of the two moving seats 2 close to each other; the clamping assembly comprises a clamping claw 3, and the clamping claw 3 is driven by a hydraulic system to clamp and fix the workpiece, and a forging box 4 is fixedly connected to the top surface of the base 1 at a middle position; a through groove 5 is opened on the end surface of the forging box 4; the groove wall surface of the through groove 5 is slidably connected to the workpiece 3; the forging box 4 is fixedly ... A plurality of evenly arranged connecting rods 6 are connected, and the connecting rods 6 are driven by a motor; a hammer head 7 is fixedly connected to one end of the connecting rod 6 away from the forging box 4; the thickness of one end of the hammer head 7 is smaller than that of the other end; a receiving groove 8 is provided on the top surface of the base 1; connecting seats 9 are installed in the receiving groove 8 and on both sides of the forging box 4, and the connecting seats 9 on both sides are symmetrical about the forging box 4; an electric push rod 10 is fixedly connected to the side away from each other of the two connecting seats 9; a support seat 11 is installed at the telescopic end of the electric push rod 10; when working, when the rod and tube are When processing a shaped workpiece, the embodiment of the present invention can be used. First, the user fixes the workpiece to be processed on the moving seat 2 at the thinner end of the hammer head 7 through the clamping assembly. Then, under the drive of the moving seat 2, one end of the workpiece to be processed is passed through the through groove in the middle of the forging box 4, and is fixed by the clamping assembly on the end face of the moving seat 2 on the other side. Then, the motor drives the connecting rod 6 to reciprocate, thereby driving the hammer head 7 at the end of the connecting rod 6 to continuously strike the surface of the workpiece to be processed, thereby continuously reducing the diameter of the workpiece and continuously increasing the length. At this time, when the moving seat 2 on one side moves the end of the workpiece to the forging box 4, the user can rotate the rotating seat 20 on the other side to set it in a vertical state, and then start the electric push rod 10, and use the electric push rod 10 to push the support seat 11 to the bottom surface of the workpiece, and finally support the support seat 11 to the surface of the workpiece, thereby ensuring that the heights of the two ends of the workpiece are consistent and will not be skewed. At the same time, it can also provide support for the middle part of the workpiece, thereby avoiding bending of the middle part of the workpiece due to excessive length, thereby affecting the final product quality.

[0032] like Figure 4As shown, the top surface of the support seat 11 is rotatably connected with a support roller 12; the diameters at both ends of the support roller 12 are larger than the diameter in the middle, and the support roller 12 is symmetrically arranged about the central axis of the rotating seat 20; during operation, when the electric push rod 10 drives the support seat 11 to rise, the support roller 12 on the top surface of the support seat 11 will contact the surface of the workpiece, and because the diameters at both ends of the support roller 12 are larger than the diameter in the middle, the workpiece will be stuck in the middle of the support roller 12, and because the support roller 12 is symmetrically arranged about the central axis of the rotating seat 20, both ends of the workpiece will be on the central axis of the rotating seat 20, thereby ensuring the straightness of the workpiece and avoiding large bending of the workpiece, which affects the processing accuracy of the final product. At the same time, when the workpiece moves on the surface of the support roller 12, the support roller 12 can also rotate, thereby reducing the friction when the workpiece moves, thereby reducing the wear on the workpiece.

[0033] like Figure 3 to Figure 4 As shown, the two connecting seats 9 are rotatably connected to the inner wall of the receiving groove 8; the ends of the two connecting seats 9 that are away from each other are fixedly connected with a rotating rod 13; the rotating rod 13 is rotatably connected to the base 1, and the rotating rod 13 penetrates the base 1 and extends to the outside of the base 1; the rotating rod 13 is fixedly connected with a gear 14 at one end outside the base 1; the two gears 14 are meshed with a tooth plate 15; the end of the tooth plate 15 away from the gear 14 is fixedly connected with a connecting plate 16, and the connecting plate 16 is installed on the side surface of the moving seat 2; when working, when one side of the moving seat 2 moves toward the forging box 4, the connecting plate 16 on one side will also push the tooth plate 15 to move together until the tooth plate 15 and the gear 14 are engaged. When the workpiece is in contact and meshing, the movable seat 2 continues to move toward the forging box 4 and drives the gear 14 to rotate 90 degrees, thereby driving the rotating rod 13 and the rotating seat 20 to rotate 90 degrees synchronously through the gear 14. At this time, the electric push rod 10 drives the supporting seat 11 and the supporting roller 12 to the surface of the workpiece, so as to support the bottom of the workpiece. Therefore, when the movable seat 2 on one side moves the end of the workpiece to a position close to the forging box 4, the rotating seat 20 on the other side can automatically rotate 90 degrees, so that the electric push rod 10 can push the supporting roller 12 to the bottom surface of the workpiece to complete the support of the workpiece, thereby avoiding manual control of the rotation of the rotating seat 20, thereby reducing the difficulty of operation of the embodiment of the present invention.

[0034] like Figure 3 to Figure 4As shown, the bottom of the receiving groove 8 is fixedly connected with baffles 17 on both sides of the forging box 4, and the baffles 17 are located between the forging box 4 and the connecting seat 9; the end of the baffle 17 close to the rotating seat 20 is inlaid with a magnet plate 18; the surface of the rotating seat 20 close to the baffle 17 has a metal plate 19, and the metal plate 19 is made of magnetizable metal; during operation, when the rotating seat 20 drives the electric push rod 10, the support seat 11 and the support roller 12 to rotate 90 degrees and is set in a vertical state, the baffle 17 on one side of the rotating seat 20 will fit with the metal plate 19 on the surface of the rotating seat 20, and because the surface of the baffle 17 is inlaid with the magnet plate 18, the baffle 17 will absorb the support seat 11, thereby fixing the position of the support seat 11, preventing the moving seat 2 from driving the tooth plate 15 to continue to move, which causes the tooth plate 15 to detach from the gear 14, and the rotating seat 20 shakes due to the movement of the workpiece on its top.

[0035] like Figure 1 , Figure 5 and Figure 6 As shown, the clamping assembly also includes a rotating seat 20, and the rotating seat 20 is rotatably connected to the moving seat 2 and driven by a motor to rotate on the end surface of the moving seat 2; the side surface of the rotating seat 20 is provided with a plurality of evenly arranged rotating grooves 21, and the rotating grooves 21 correspond to the clamping jaws 3 one by one; the clamping jaws 3 are rotatably connected inside the rotating grooves 21 and are controlled by a hydraulic system; the rotating seat 20 is provided with a receiving groove 22 at the middle position at one end away from the moving seat 2; a push rod 23 is slidably connected in the receiving groove 22; a driving assembly is installed between the push rod 23 and the receiving groove 22; the driving assembly is used to push the push rod 23 out of the receiving groove 22; the working During operation, when the clamping assembly needs to clamp the workpiece, the hydraulic system will control the rotation of the jaw 3 at the rotating groove 21, so that the parts of the jaw 3 located outside the rotating groove 21 are brought closer to each other, thereby clamping the workpiece. When the jaw 3 and the workpiece move to the forging box 4, the jaw 3 will deflect in the direction away from the workpiece, thereby releasing the workpiece. At the same time, the push rod 23 in the receiving groove 22 will also be pushed out of the receiving groove 22 under the drive of the driving assembly, and press against the end of the workpiece to provide thrust for the workpiece, thereby avoiding that when the end of the workpiece is completely entered between the hammer heads 7, only one side of the moving seat 2 pulls the workpiece, resulting in uneven force at both ends of the workpiece, thereby affecting the forging hammer effect of the workpiece.

[0036] like Figure 6 to Figure 7As shown, the driving rod assembly includes a connecting tube 24, and the connecting tube 24 is fixedly connected to the bottom of the clamping jaw 3; an extrusion rod 25 is slidably connected in the connecting tube 24; a spring 26 is fixedly connected between the extrusion rod 25 and the connecting tube 24; a groove connecting the extrusion rod 25 is provided on the inner wall of the rotating groove 21 on one side close to the accommodating groove 22, and the connecting groove 27 is connected to the inside of the accommodating groove 22; a clamping groove 28 is provided on the surface of the push rod 23 at a position corresponding to the connecting groove 27; the extrusion rod 25 is adapted to the connecting groove 27 and the clamping groove 28; a spring 29 is fixedly connected between the push rod 23 and the bottom of the accommodating groove 22, and the end of the push rod 23 away from the spring is arranged in an arc shape; during operation, when the clamping jaw 3 deflects in the direction away from the workpiece, the connecting tube 24 and the extrusion rod 25 at the bottom of the clamping jaw 3 will also deflect under the drive of the clamping jaw 3. The connecting tube 24 drives the extruding rod 25 to rotate to the inside of the connecting groove 27, and then the extruding rod 25 is pushed into the groove 28 on the surface of the ejector 23 under the elastic force of the spring 1 26. As the jaws 3 continue to rotate, the extruding tube also drives the extruding rod 25 to rotate, and then the extruding rod 25 pushes the ejector 23, so that the ejector 23 is brought out of the receiving groove 22 and the spring 2 29 is stretched. When the multiple jaws 3 are closed, the extruding rod 25 no longer pushes the ejector 23, and the stretched spring 29 is restored, thereby driving the ejector 23 to be retracted into the receiving groove 22, thereby realizing the automatic ejection of the ejector 23 when the jaws 3 release the workpiece. At the same time, the end of the ejector 23 is arranged in an arc shape, which can reduce the contact area between the ejector 23 and the end face of the workpiece, thereby reducing the friction of the workpiece during rotation, thereby reducing the wear of the workpiece.

[0037] like Figure 1 , Figure 3 and Figure 5 As shown, there are push plates 30 on both sides of the base 1; the push plates 30 are located between the connecting plate 16 and the base 1; a hydraulic rod 31 is inlaid on the surface of the movable seat 2 at the corresponding position of the tooth plate, and the telescopic end of the hydraulic rod 31 is fixedly connected to the push plate 30; the end of the connecting plate 16 away from the tooth plate 15 is fixedly connected to a slide bar 32; the slide bar 32 is slidably connected to the movable seat 2; a spring 33 is fixedly connected between the connecting plate 16 and the movable seat 2, and the spring 33 is sleeved on the outside of the slide bar 32; during operation, when the length of the workpiece is small, the movable seats 2 on both sides will be close to the forging box 4. At this time, if the rotating seat 2 0 drives the electric push rod 10 to rotate to a vertical state, which will affect the movement of the moving seat 2. Therefore, the user can start the hydraulic rod 31, and the hydraulic rod 31 drives the push plate 30 to move in a direction away from the base 1, thereby squeezing the connecting plate 16, so that the connecting plate 16 also moves in a direction away from the base 1, and pulls the slide bar 32 and the spring three 33. At this time, the tooth plate 15 at the end of the connecting plate 16 cannot normally mesh with the gear 14, thereby avoiding that when processing a shorter workpiece, the rotating seats 20 on both sides drive the electric push rod 10 to rotate to a vertical state, thereby affecting the normal movement of the moving seat 2.

[0038] like Figure 1 and Figure 8 As shown, a connecting frame 34 is provided on the thicker side of the base 1 away from the hammer head 7, and the connecting frame 34 is located on the same side of the toothed plate 15 on the side; the connecting frame 34 is rotatably connected to the base 1, and the connecting frame 34 is arranged in an arc shape; a gear 2 35 is rotatably connected to the surface of the base 1 at the connecting frame 34; the gear 2 35 and the connecting frame 34 are connected through a gear set; a toothed plate 2 36 is fixedly connected to the bottom surface of the connecting plate 16 and one end close to the gear 2 35; a receiving assembly is installed on the end of the connecting frame 34 away from the base 1; when working, When loading the workpiece, the workpiece that has been burned red hot is transported to the top surface of the receiving component by the conveying system, and then the moving seat 2 moves toward the connecting frame 34, thereby driving the tooth plate 2 36 at the bottom of the connecting plate 16 to engage with the gear 2 35, thereby driving the gear 2 35 to rotate, and then the rotating gear 2 35 drives the connecting frame 34 to rotate through the gear set, thereby moving the receiving component and the workpiece at the end of the connecting frame 34 to the rotating seat 20 at the end of the moving seat 2, and then the clamping claw 3 at the rotating seat 20 can clamp the workpiece, so as to facilitate the user to complete the loading operation.

[0039] like Figure 1 and Figure 8 As shown, the receiving assembly includes a receiving frame 37, and the receiving frame 37 is arranged in an arc shape; the receiving frame 37 is rotatably connected to the end of the connecting frame 34 away from the base 1, and the receiving frame 37 is driven by a servo motor; when working, when the workpiece moves to the top surface of the receiving frame 37, the connecting frame 34 is deflected under the drive of the gear set, and during the rotation of the connecting frame 34, the servo motor will also drive the receiving frame 37 to rotate, so that the receiving frame 37 is always kept in a horizontal setting, thereby ensuring that the workpiece is following the connecting frame During the movement of 34, it will not detach from the top surface of the receiving frame 37. When the clamping jaws 3 complete the clamping of the workpiece, the servo motor will drive the receiving frame 37 to rotate to a vertical state, and then the moving seat 2 will drive the tooth plate 2 36 to move toward the forging box 4. The tooth plate 2 36 meshes with the gear 2 35 and drives the gear 2 35 to rotate, so that the connecting frame 34 rotates to a horizontal position. Since the receiving frame 37 rotates to a vertical state, it will not collide with the workpiece or the clamping jaws 3, thereby avoiding damage to both.

[0040] like Figure 8As shown, connecting columns 38 are slidably connected between the gaps of the receiving surface; the top surface of the connecting column 38 is rotatably connected to a roller 39; the rotating shaft of the roller 39 is perpendicular to the base 1; a limiting frame 40 is provided at the bottom of the receiving frame 37 on one side of the base 1; during operation, when the connecting frame 34 is horizontally arranged, the receiving frame 37 is also horizontally arranged under the drive of the servo motor, and at this time, the connecting column 38 will push the roller 39 out of the surface of the receiving frame 37 under the extrusion of the limiting frame 40, so that the workpiece entering the top surface of the receiving frame 37 can reduce friction through the rolling of the roller 39, and when the connecting frame 34 rotates, the connecting column 38 is no longer squeezed by the limiting frame 40, and the connecting column 38 drives the roller 39 to be retracted into the gap on the surface of the receiving frame 37 under the action of gravity, thereby preventing the workpiece from detaching from the surface of the receiving frame 37 due to the rolling of the roller 39 during the rotation of the workpiece.

[0041] During operation, when processing rod-shaped and tubular workpieces, the embodiment of the present invention can be used. First, the user fixes the workpiece to be processed on the moving seat 2 at the thinner end of the hammer head 7 through the clamping assembly. Then, under the drive of the moving seat 2, one end of the workpiece to be processed passes through the through groove in the middle of the forging box 4 and is fixed by the clamping assembly on the end face of the moving seat 2 on the other side. Then, the motor drives the connecting rod 6 to reciprocate, thereby driving the hammer head 7 at the end of the connecting rod 6 to continuously strike the surface of the workpiece to be processed, thereby continuously reducing the diameter of the workpiece, and at the same time, the length will also be reduced. When the movable seat 2 on one side moves the end of the workpiece to the forging box 4, the user can rotate the movable seat 20 on the other side to set it in a vertical state, and then start the electric push rod 10 to push the support seat 11 to the bottom surface of the workpiece through the electric push rod 10, and finally support the support seat 11 to the surface of the workpiece, thereby ensuring that the heights of both ends of the workpiece are consistent and will not be skewed, and at the same time, it can provide support for the middle part of the workpiece to avoid bending in the middle of the workpiece due to excessive length, thereby affecting the final product quality.

[0042] When the electric push rod 10 drives the support seat 11 to rise, the support roller 12 on the top surface of the support seat 11 will contact the surface of the workpiece. Since the diameters of the two ends of the support roller 12 are larger than the diameter in the middle, the workpiece will be stuck in the middle of the support roller 12. Since the support roller 12 is symmetrically arranged about the central axis of the rotating seat 20, both ends of the workpiece will be on the central axis of the rotating seat 20, thereby ensuring the straightness of the workpiece and avoiding large bending of the workpiece, which affects the processing accuracy of the final product. At the same time, when the workpiece moves on the surface of the support roller 12, the support roller 12 can also rotate, thereby reducing the friction when the workpiece moves, thereby reducing the wear on the workpiece.

[0043] When one side of the moving seat 2 moves toward the forging box 4, the connecting plate 16 on one side will also push the tooth plate 15 to move at the same time until the tooth plate 15 contacts and meshes with the gear 14. At this time, the moving seat 2 continues to move toward the forging box 4 and drives the gear 14 to rotate 90 degrees, thereby driving the rotating rod 13 and the rotating seat 20 to rotate 90 degrees synchronously through the gear 14. At this time, the electric push rod 10 drives the support seat 11 and the support roller 12 to the surface of the workpiece, so as to support the bottom of the workpiece. Therefore, when the moving seat 2 on one side moves the end of the workpiece to a position close to the forging box 4, the rotating seat 20 on the other side can automatically rotate 90 degrees, so that the electric push rod 10 can push the support roller 12 to the bottom surface of the workpiece to complete the support of the workpiece, thereby avoiding manual control of the rotation of the rotating seat 20, thereby reducing the operating difficulty of the embodiment of the present invention.

[0044] When the rotating seat 20 drives the electric push rod 10, the supporting seat 11 and the supporting roller 12 to rotate 90 degrees and is set in a vertical state, the baffle 17 on one side of the rotating seat 20 will fit with the metal plate 19 on the surface of the rotating seat 20. Since the surface of the baffle 17 is inlaid with a magnet plate 18, the baffle 17 will adsorb the supporting seat 11, thereby fixing the position of the supporting seat 11 to prevent the moving seat 2 from driving the tooth plate 15 to continue to move, which will cause the tooth plate 15 to disengage from the gear 14, and the rotating seat 20 will shake due to the movement of the workpiece on its top.

[0045] When the clamping assembly needs to clamp the workpiece, the hydraulic system will control the rotation of the jaw 3 at the rotating groove 21, so that the parts of the jaw 3 located outside the rotating groove 21 are brought closer to each other, thereby clamping the workpiece. When the jaw 3 and the workpiece move to the forging box 4, the jaw 3 will deflect in the direction away from the workpiece, thereby releasing the workpiece. At the same time, the push rod 23 in the receiving groove 22 will also be pushed out of the receiving groove 22 under the drive of the driving assembly, and press against the end of the workpiece to provide thrust for the workpiece, thereby avoiding that when the end of the workpiece is completely entered between the hammer heads 7, only one side of the moving seat 2 pulls the workpiece, resulting in uneven force at both ends of the workpiece, thereby affecting the forging hammer effect of the workpiece.

[0046] When the clamping jaws 3 are deflected in the direction away from the workpiece, the connecting tube 24 and the extruding rod 25 at the bottom of the clamping jaws 3 will also be deflected under the drive of the clamping jaws 3, and finally the connecting tube 24 drives the extruding rod 25 to rotate into the connecting groove 27, and then the extruding rod 25 is pushed into the groove 28 on the surface of the ejector rod 23 under the elastic force of the spring 1 26. As the clamping jaws 3 continue to rotate, the extruding tube will also drive the extruding rod 25 to rotate, and then the extruding rod 25 will push the ejector rod 23, so that the ejector rod 23 is brought out of the accommodating groove 22 and the spring 2 29 is stretched. When the multiple clamping jaws 3 are closed, the extruding rod 25 no longer pushes the ejector rod 23, and the stretched spring 2 29 is restored, thereby driving the ejector rod 23 to be retracted into the accommodating groove 22, thereby realizing the automatic ejection of the ejector rod 23 when the clamping jaws 3 release the workpiece. At the same time, the end of the ejector rod 23 is arranged in an arc shape, which can reduce the contact area between the ejector rod 23 and the end face of the workpiece, thereby reducing the friction of the workpiece during rotation, thereby reducing the wear of the workpiece.

[0047] When the length of the workpiece is small, the moving seats 2 on both sides will be close to the forging box 4. At this time, if the rotating seat 20 drives the electric push rod 10 to rotate to a vertical state, it will affect the movement of the moving seat 2. Therefore, the user can start the hydraulic rod 31, and the hydraulic rod 31 drives the push plate 30 to move in the direction away from the base 1, thereby squeezing the connecting plate 16, so that the connecting plate 16 also moves in the direction away from the base 1, and pulls the slide bar 32 and the spring three 33. At this time, the tooth plate 15 at the end of the connecting plate 16 cannot normally engage with the gear 14, thereby avoiding the rotating seats 20 on both sides driving the electric push rod 10 to rotate to a vertical state when processing shorter workpieces, thereby affecting the normal movement of the moving seat 2.

[0048] When loading the workpiece, the workpiece that has been burned red hot is transported by the conveying system to the top surface of the receiving assembly, and then the moving seat 2 moves toward the connecting frame 34, thereby driving the tooth plate 2 36 at the bottom of the connecting plate 16 to engage with the gear 2 35, thereby driving the gear 2 35 to rotate, and then the rotating gear 2 35 drives the connecting frame 34 to rotate through the gear set, thereby moving the receiving assembly at the end of the connecting frame 34 and the workpiece to the rotating seat 20 at the end of the moving seat 2, and then the clamping claw 3 at the rotating seat 20 can clamp the workpiece, so as to facilitate the user to complete the loading operation.

[0049] When the workpiece moves to the top surface of the receiving frame 37, the connecting frame 34 is deflected under the drive of the gear set, and during the rotation of the connecting frame 34, the servo motor will also drive the receiving frame 37 to rotate, so that the receiving frame 37 always remains in a horizontal setting, thereby ensuring that the workpiece will not detach from the top surface of the receiving frame 37 while following the movement of the connecting frame 34, and when the clamp 3 completes the clamping of the workpiece, the servo motor will drive the receiving frame 37 to rotate to a vertical state, and then the moving seat 2 will drive the tooth plate 2 36 to move toward the forging box 4, and the tooth plate 2 36 will mesh with the gear 2 35 and drive the gear 2 35 to rotate, so that the connecting frame 34 rotates to a horizontal position, and since the receiving frame 37 rotates to a vertical state, it will not collide with the workpiece or the clamp 3, thereby avoiding damage to both.

[0050] When the connecting frame 34 is set horizontally, the receiving frame 37 is also set horizontally under the drive of the servo motor. At this time, the connecting column 38 will push the roller 39 out of the surface of the receiving frame 37 under the squeezing of the limit frame 40, so that the workpiece entering the top surface of the receiving frame 37 can reduce the friction through the rolling of the roller 39. When the connecting frame 34 rotates, the connecting column 38 is no longer squeezed by the limit frame 40. The connecting column 38 drives the roller 39 to retract into the gap on the surface of the receiving frame 37 under the action of gravity, thereby preventing the workpiece from detaching from the surface of the receiving frame 37 due to the rolling of the roller 39 during the rotation of the workpiece.
