Description

Technical Field

[0001] The present invention relates to metal forging technology, in particular to an intelligent numerically controlled forging machine. Background Art

[0002] A forging press is a mechanical device used for the plastic processing of metal materials. It applies enormous pressure to place the heated or unheated metal material in a die. The pressure and impact of the die cause the metal material to undergo plastic deformation, thus obtaining the desired part or product. A forging press is usually composed of a frame, a slide, a pressure system, a transmission system, a lubrication system, and a control system. Depending on the different working methods and structural forms, forging presses can be divided into various types such as stamping presses, presses, and forging presses. Forging presses are widely used in industries such as automobiles, aerospace, ships, metallurgy, petrochemicals, and power equipment to manufacture various parts, tools, mechanical equipment, and engineering structures. They are characterized by high efficiency, high precision, high stability, and reliability, making them one of the indispensable key equipment in the field of metal processing.

[0003] For example, the authorization announcement number is CN113426940B, the authorization announcement date is June 14, 2023, and the name is an invention patent for a safety forging machine for processing automotive parts, including: a punch, a driver, a support frame, a telescopic rod, and a base. The upper end of the punch passes through the support frame, and the outer ring of the punch is nested and connected with the inner ring of the driver. The driver is detachably installed at the upper end of the support frame, and the inner side of the support frame is embedded and connected to the upper end of the telescopic rod. The lower end of the telescopic rod is embedded in the inner side of the base. During forging, the present invention uses a swing mechanism to fix and clamp the side of the workpiece. When the workpiece expands due to heat, the side of the workpiece will squeeze the block, so that the swing block will rotate around the rotating shaft, thereby squeezing the elastic block. When the workpiece shrinks, the elastic block can be used to push the swing block to return to its original shape. During the expansion process, the block can swing with the expansion of the workpiece, thereby avoiding the workpiece from squeezing the fixture, resulting in the fixture being unable to firmly clamp the workpiece, thereby affecting the processing efficiency.

[0004] In the prior art, when it comes to bar-shaped metal blocks, clamping claws are often used for clamping, and then the bar-shaped metal blocks are gradually forged through the cooperation of the clamping claws and the die. However, during such forging, the clamping claws exert a certain amount of pressure on the surface of the metal block. At the same time, the huge pressure during forging produces huge vibrations on the metal material and the clamping claws simultaneously, causing the clamping claws to easily fatigue and have a short service life.

[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] like Figure 1-8 As shown, an embodiment of the present invention provides an intelligent CNC forging machine, including a die 1 and a base 2 for fixing the die 1, and also includes two clamping claws 3 connected in a cross-rotating manner. The two clamping claws 3 are used to clamp the material block. When the die 1 forges the material block, the two clamping claws 3 release the clamping of the material block.

[0031] Specifically in this embodiment, the die 1 in the forging machine is generally divided into an upper die and a lower die, and the material block is forged by the cooperation of the upper die and the lower die. The present invention also includes a hydraulic unit, a transmission unit and a control unit for driving the die 1 to move. Since the forging process and some forging equipment are prior art, their specific structure and working principle are not described in detail here; the base 2 is detachably mounted on the ground, and the lower end of the base 2 is a table body, and its bottom end contacts the ground to make it more stable during the forging process. The upper end of the base 2 is fixedly connected to a mounting cover, and the hydraulic unit, transmission unit and control unit are arranged inside the mounting cover. The base 2 in the present invention is also suitable for various large-scale forging equipment; The clamping claw 3 is used to clamp the end of the strip-shaped material block; when the die 1 needs to forge the material block, the clamping claw 3 drives the material block to move to the die 1, and then the die 1 is used to forge the side of the material block away from the clamping claw 3. After the forging is completed there, the clamping claw 3 gradually drives the material block to continue moving and forges the unforged part, and continues forging in this way. When the material block is forged to the clamping position, the clamping claw 3 is released from the material block, and the die 1 is used to forge the material block to deform it. After the forging is completed, the clamping claw 3 re-clamps the forged material block, avoiding the huge vibration generated synchronously by the metal material and the clamping claw, making the clamping claw less likely to fatigue and extending the service life of the clamping claw.

[0032] In another embodiment provided by the present invention, a pressure detection unit (not shown in the figure) is provided on the die 1, and the pressure detection unit includes a pressure sensor, and the pressure detection unit is used to detect the pressure on the die 1 in real time.

[0033] In another embodiment provided by the present invention, a driving unit is further included, which is connected to the clamping claw 3. The driving unit is used to drive the clamping claw 3 to contract or open so that the clamping claw 3 clamps or releases the material block. This is existing technology and will not be described in detail.

[0034] In another embodiment provided by the present invention, a PLC controller 5 is further included. The pressure detection unit and the drive unit are both electrically connected to the PLC controller 5. The PLC controller 5 is used to receive the pressure signal output by the pressure detection unit and control the operation of the drive unit. The PLC controller 5 can also determine whether the actual pressure data uploaded by the pressure detection unit is gradually rising or falling. When the pressure detection unit detects that the pressure on the die 1 is gradually increasing, the PLC controller 5 controls the drive unit to open the clamping jaw 3; when the pressure detection unit detects that the pressure on the die 1 is gradually decreasing, the PLC controller 5 controls the drive unit to make the clamping jaw 3 shrink in time to clamp the material block.

[0035] In another embodiment provided by the present invention, a forging area 21 is opened in the middle of the base 2, and the die 1 is located in the forging area 21. The forging area 21 provides a working place for the die 1. A mounting protrusion 22 is relatively fixed on the base 2, which is used to fix the base 2 to a fixed foundation such as a concrete foundation.

[0036] In another embodiment provided by the present invention, it also includes an installation frame 42, the driving unit is fixed in the installation frame 42, the two clamping claws 3 are connected together by a cross-rotation shaft, and the rotating shaft is fixed in the installation frame 42. When the installation frame 42 is moved, the clamping claws 3 and the material block can be moved synchronously.

[0037] In the prior art, most of the clamping claws 3 need to rotate to clamp. Therefore, most of the clamping claws 3 clamp the material block in point contact to adapt to the material blocks after forging of different diameters. However, during point contact, the contact area between the clamping claw 3 and the material block is small and the unit pressure is large, which easily causes irregular deformation of the clamping position of the material block. Therefore, this embodiment provides a solution to the above technical problems. Two connecting branches 43 are relatively fixed in the mounting frame 42. The end of the connecting branch 43 away from the mounting frame 42 is rotatably mounted with an elastic elastic member. The retractable rod 44 includes a fixed section and a movable section that are sleeved at the ends. The movable section is slidably connected relative to the fixed section to achieve retraction. The sleeve portion is provided with an elastic member to achieve retraction. The retractable rod 44 can rotate with its own central axis as the rotation axis. The extension direction of the movable section of the retractable rod 44 is perpendicular to the material block. The fixed section and the movable section of the retractable rod 44 cannot rotate relative to each other. The end of the clamping claw 3 away from the mounting frame 42 is provided with a through slot 45. The movable section of the retractable rod 44 is penetrated by the retractable rod 44. A clamping portion 46 is detachably mounted through the slot 45. The clamping portion 46 is a plate-like structure. The clamping portion 46 is used to clamp the material block. The clamping claw 3 can drive the clamping portion 46 to move. Two protrusions 47 are relatively arranged on the clamping claw 3. The two protrusions 47 are relatively arranged with the elastic telescopic rod 44 as the center. The two protrusions 47 are pressed against the end surface of the clamping portion 46 away from the material block. In addition, the elastic telescopic rod 44 can also contract during the outward expansion of the clamping claw 3, so that the clamping portion 46 is tightly attached to the protrusions 47. When it is necessary to clamp the material block, the material block is placed between the clamping parts 46, and the clamping ends of the two clamping claws 3 are driven to contract by the driving unit, so that the protrusion 47 pushes the clamping part 46 to move in the direction close to the material block. Since the clamping part 46 is restricted by the elastic telescopic rod 44 and can only move in the direction perpendicular to the material block, the clamping part 46 is pressed on the material block in the direction perpendicular to the side of the material block, thereby clamping the material block. Since the contact area between the clamping part 46 and the side of the material block is large, the unit pressure is small, and the clamping is more stable.

[0038] As for the clamping claw 3, a single clamping claw 3 is formed by fixing a driving section and a clamping section, the driving section is connected to the driving unit, and the angle between the driving section and the clamping section is greater than 90 degrees, preferably 120 degrees, so that the driving section does not affect the movement of the clamping section. The driving section is a rod-shaped structure, but the clamping section can be a strip-shaped rod-shaped structure or a curved rod-shaped structure. When the driving sections on the two clamping claws 3 move away from each other, the clamping sections on the two clamping claws 3 approach each other and clamp the material block. The clamping sections clamp on the left and right sides of the material block to facilitate forging the material block.

[0039] Furthermore, the above technical solution clamps the material block by contracting the clamping claw 3 and pushing the clamping portion 46. However, after forging, the length of the material block becomes longer, and the size of the cross-section formed by the height and width becomes smaller. That is to say, when continuing to clamp, the amplitude of the contraction and rotation of the clamping claw 3 becomes larger, that is, the rotation amplitude of the clamping section becomes larger to push the clamping portion 46 for clamping. In this way, the protrusion 47 on the side of the two protrusions 47 close to the mounting frame 42 will gradually move away from the clamping portion 46. When clamping, the material block will be unevenly stressed, which will affect the clamping effect and may also cause irregular deformation on the material block. For this reason, a solution of this embodiment is to The scheme includes a top pressing component 48, wherein the convex block 47 near the side of the mounting frame 42 is replaced by a sliding convex rod 481, and the top pressing component 48 includes a sliding convex rod 481 slidably mounted on the clamping claw 3, and the sliding convex rod 481 can only slide perpendicular to the clamping end of the clamping claw 3, and a bracket 482 is also fixed on the clamping section of the clamping claw 3, and a screw 483 is rotatably mounted on the bracket 482. A screw hole is provided at one end of the sliding convex rod 481 near the connecting branch 43, and the screw 483 is threadedly connected in the screw hole. A spool 485 is fixed on the side of the screw 483 near the connecting branch 43, and the spool 485 is fixed on the side of the screw 483 near the connecting branch 43. 85 is wound with a connecting rope 486, and a torsion spring 487 is sleeved on the lead screw 483. The torsion spring 487 is connected between the spool 485 and the bracket 482. The torsion spring 487 keeps the connecting rope 486 in a tensioned state at all times. When a material block with a reduced cross-sectional size needs to be clamped, the rotation angle of the clamping claw 3 increases. At this time, the protrusion 47 on the side away from the mounting frame 42 pushes the clamping portion 46 out and approaches the material block. At the same time, the clamping section of the clamping claw 3 gradually moves away from the connecting branch 43. At this time, the connecting rope 486 is stretched and synchronously drives the spool 485 to rotate, and the rotation of the spool 485 drives the wire rope 486 to rotate. The lever 483 rotates, and the rotation of the lead screw 483 drives the sliding protrusion 481 to slide out so that it remains in close contact with the clamping portion 46. Therefore, no matter how the clamping claw 3 rotates to clamp, the sliding protrusion 481 and the protrusion 47 on the side away from the mounting frame 42 can be kept in close contact with the clamping portion 46. In this way, when the clamping portion 46 is clamped, the force on the clamping portion 46 can be uniform, and the self-locking of the lead screw 483 can stabilize the movement of the sliding protrusion 481, so that the sliding protrusion 481 will not slide in the opposite direction when clamped. Through the above technical solution, it is ensured that the material block will be subjected to uniform force during clamping, and irregular deformation of the material block is avoided.

[0040] In another embodiment provided by the present invention, the clamping portion 46 can be a square plate or a circular plate, and the end of the clamping portion 46 close to the material block is a resistance-increasing surface, which is used to increase friction to ensure the clamping effect.

[0041] In another embodiment provided by the present invention, it also includes a linear motion unit (not shown in the figure), which is used to drive the mounting frame 42 to perform linear motion, so that the clamping claw 3 drives the material block to perform linear motion, and also includes a rotation unit, which is used to drive the mounting frame 42 to rotate with the clamping center as the rotation center, so that multiple surfaces of the strip-shaped material block can be forged; the rotation unit is connected between the linear motion unit and the mounting frame 42, and through the cooperation of the linear motion unit and the rotation unit, each surface of the material block can be gradually forged; when one side of the material block is forged, the mounting frame 42 is driven by the rotation unit to rotate 90 degrees, so that the other side of the material block is facing upward and corresponding to the upper die, and this is flipped three times to complete the forging of the four end faces of a certain section of the strip-shaped material block, and then the mounting frame 42 is driven by the linear motion unit to move in a direction close to the material block, so that the other section of the strip-shaped material block that has not been forged is placed on the lower die, and the above-mentioned process of rotation after forging is repeated.

[0042] In another embodiment provided by the present invention, the die 1 includes an upper die and a lower die, and the upper die and the lower die are arranged in a corresponding manner. The lower die is fixed at the bottom of the forging area 21 and is used to support the material block, and the upper die is slidably installed in the forging area 21 and is used for forging.

[0043] Furthermore, when the material block is forged to the vicinity of the clamping position, for the bar-shaped metal material block, since the upper die moves in the vertical direction, each forging is also the side of the material block facing upward, so the clamping claws 3 need to be kept on the left and right sides of the material block during forging. That is to say, after the forging of the upper end face is completed, the mounting frame 42 is driven by the rotating unit to rotate 90 degrees, so that the material block can be rotated 90 degrees and the adjacent unforged surface can face upward. However, at this time, the clamping claws 3 will move to the bottom of the material block and make rigid contact with the lower die, which will also make it difficult to open the clamping claws 3, and it is even impossible to forge directly. Therefore, in the prior art, to forge the clamped position , which requires the joint cooperation of the clamping claw 3, the rotating unit and the linear motion unit, and the operation is cumbersome and inefficient. For this reason, the present embodiment provides a further solution to the above technical problems, including a driving motor 49, which is detachably mounted on the connecting branch 43 through a supporting portion, and the output end of the driving motor 49 is connected to the fixed end of the elastic telescopic rod 44, and the driving motor 49 can drive the elastic telescopic rod 44 to rotate; in the present embodiment, it should be noted that in order to enable most of the material block to be forged, the prior art generally clamps a certain end of the material block in the length direction, and then gradually pushes and Forging is different from the prior art. In this embodiment, the initial material block clamping position is near the middle of the material block. In this way, the instability factor caused by only clamping the end of the material block during the transfer of the material block can be reduced, and the cantilever beam phenomenon that occurs during the transfer of the material block can also be avoided. During operation, when forging is near the middle of the material block, the clamping part 46 clamps the middle of the material block, and then the elastic telescopic rod 44 is further driven to rotate by the driving motor 49. In this way, the two clamping parts 46 can be driven to rotate synchronously. Since the clamping part 46 clamps the material block, the material block rotates with the axis of the elastic telescopic rod 44 as the center. When it rotates 180 degrees, it stops rotating, and then the clamping part 46 is released and the position near the middle of the forged material block is clamped. In this way, the clamping part 46 and the material block are pushed to move synchronously and forged by the linear motion unit. At this time, the clamping position has been forged, and the clamping part 46 will not affect the overall forging of the material block. Moreover, the operation is quick and convenient, which helps to improve work efficiency (in this embodiment, since the metal material block needs to be rotated 180 degrees, the length of the metal material block itself is limited, and the length of the clamping claw 3 is also limited. The length of the clamping section of the clamping claw 3 is not less than half the length of the metal material block after forging).

[0044] Furthermore, when some high-temperature metal blocks are placed in the air, an oxide layer will be generated on their surface. When the high-temperature material blocks are forged, the oxide layer on their surface will be crushed and fall off, but some oxide layers will still adhere to the material blocks. The residual oxide layer will reduce the surface quality of the metal blocks, and produce defects such as cracks or pores, affecting the corrosion resistance and performance of the material blocks. For this reason, this embodiment proposes a further solution based on the above technical solution to solve this technical problem. In this embodiment, the movable end of the elastic telescopic rod 44 is rotatably connected to the clamping part 46. A plurality of inner grooves 461 arranged in a semicircular pattern are provided on the end surface of the clamping part 46 away from the material block. The clamping part 46 A plurality of outer protrusions 462 arranged in a semicircular shape are further formed on one end surface away from the material block. The inner grooves 461 and the outer protrusions 462 are the same in number and correspond one to one. The plurality of inner grooves 461 and the plurality of outer protrusions 462 are on the same virtual circle. The center position of the virtual circle coincides with the axis position of the elastic telescopic rod 44. When the clamping portion 46 does not rotate, the two protrusions 47 will not contact the inner groove 461 or the outer protrusion 462. The straight-line distance between the two protrusions 47 is equal to the diameter of the above-mentioned virtual circle. That is to say, when the clamping portion 46 rotates, the protrusion 47 will contact the inner groove 461 or the outer protrusion 462. It should be noted that on the two opposing clamping portions 46, one of them , the arrangement positions of the inner groove 461 and the outer protrusion 462 are opposite; taking one of the clamping parts 46 as an example, when the clamping part 46 drives the material block to rotate, the protrusion 47 on the side close to the mounting frame 42 will gradually contact the outer protrusion 462 and push the clamping part 46 to rotate. At the same time, the protrusion 47 on the side away from the mounting frame 42 will gradually contact the inner groove 461 to rotate the clamping part 46, and the rotation direction is consistent. Therefore, it will drive the clamping part 46 to rotate slightly. At this time, the arrangement of the inner groove 461 and the outer protrusion 462 on the other clamping part 46 can also prompt the clamping part 46 to rotate slightly in the same direction; the clamping part 46 continues to rotate, and the protrusion 47 on the side close to the mounting frame 42 The protrusion 47 on the side will gradually separate from the outer protrusion 462, and the protrusion 47 on the side away from the installation frame 42 will gradually disengage from the inner groove 461, so that the clamping part 46 is gradually reset, and the movement of the other clamping part 46 also promotes the reset process, which will not be elaborated here; in summary, during the rotation of the clamping part 46, the clamping part 46 can be continuously rotated and reset in a small amplitude, which also drives the material block itself to vibrate, so that the oxide layer residue remaining on the surface of the material block can be shaken off. This embodiment utilizes the cooperation of the protrusion 47 and the clamping part 46, and also utilizes the rotation process of the clamping part 46, so that the material block is passively vibrated during the rotation process, and the cracked oxide layer attached to the material block can be shaken off.

[0045] In addition, in the above embodiment, the metal material block may not be rotated 180 degrees, but only rotated at a specific angle within the range of 30 to 130 degrees, so as to vibrate the metal material block alone and shake off the oxide layer residue remaining on the surface of the material block.

[0046] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
