Description

Technical Field

[0002] Forging is a processing method that uses forging machinery to apply pressure to metal blanks to make them plastically deform to obtain forgings with certain mechanical properties, shapes and sizes. It is one of the two major components of forging (forging and stamping). Forging can eliminate defects such as loose cast metal produced during the smelting process and optimize the microstructure. At the same time, due to the preservation of complete metal flow lines, the mechanical properties of forgings are generally better than those of castings of the same material.

However, during the forging process, the force-bearing surface of the hardware blank needs to be adjusted frequently by manual labor, which not only increases the labor intensity of the staff, but also affects the forging efficiency. Moreover, when the manual labor approaches the forging equipment to adjust the force-bearing surface of the hardware, forging accidents are prone to occur.

[0048] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0049] Example 1: Reference Figure 1 and Figure 2 The forging forming machine relates to the field of hardware forging technology. The structure includes a forging table 1. The bottom of the forging table 1 is fixed with a base 2 by bolts to ensure the stability of the whole equipment. The top of the forging table 1 is fixed with a gantry 3 by bolts. The structure of the gantry 3 is designed to provide sufficient support and stability. A hydraulic cylinder 4 is fixed through the gantry 3. The bottom end of the hydraulic cylinder 4 is fixed with a forging hammer 5 by bolts. The piston rod of the hydraulic cylinder 4 can drive the forging hammer 5 to move up and down. The hydraulic cylinder 4 and the forging hammer 5 cooperate to forge the blank.

[0050] Reference Figure 5 and Figure 6 The forging table 1 is provided with a through hole 6, and two forging plates 8 are rotatably provided in the through hole 6. The forging plates 8 are used to place the blank. During the forging process, the forging plates 8 can be rotated so as to forge different parts of the blank. Two support columns 28 are provided below the forging table 1, and support plates 29 are fixed to the tops of the support columns 28. The support plates 29 are used to support the bottom of the forging plates 8 to ensure the stability of the forging plates 8.

[0051] Reference Figure 1-Figure 3 A rotating ring 10 is rotated on the top of the forging table 1, and two fixed platforms 12 are fixed to the top of the rotating ring 10 by bolts. A clamping plate 19 is provided on the side where the two fixed platforms 12 are close to each other. The clamping plate 19 is used to clamp the blank to ensure the stability of the blank during the forging process.

[0052] Reference Figure 2-Figure 4In order to realize the turning over of the blank, a turning over structure is provided in the fixed platform 12 in this embodiment. The turning over structure includes a screw rod 13 that slides through the fixed platform 12, a push rod 18 is rotated on the side of the clamping plate 19 close to the screw rod 13, one end of the push rod 18 slides and extends into the screw rod 13, a first spring 17 is fixed on the end of the push rod 18 away from the clamping plate 19, and the end of the first spring 17 away from the push rod 18 contacts the inner wall of one side of the screw rod 13. The first gear ring 14 and the first gear 15 are rotatably connected on the side of the fixed platform 12 away from the push rod 18, and the first gear ring 14 is meshed with the first gear 15, the inner wall of the first gear ring 14 is provided with an internal thread, and the first gear ring 14 is threadedly connected with the screw rod 13 through the internal thread. When the motor drives the first gear 15 to rotate, the first gear 15 drives the first gear ring 14 to rotate, and the first gear ring 14 cooperates with the screw rod 13 to push the screw rod 13 to move. The screw 13 drives the push rod 18 and the clamping plate 19 to move toward the middle through the first spring 17 to clamp the blank. The fixed platform 12 is rotatably connected with the second gear 22 and the second gear ring 20 on the side away from the first gear 15, and the second gear 22 is meshed with the second gear ring 20. A plurality of telescopic rods 21 are fixed on the side of the second gear ring 20 away from the first gear 15, and one end of each of the plurality of telescopic rods 21 is fixedly connected to one side of the clamping plate 19. When the motor drives the second gear 22 to rotate, the second gear 22 drives the second gear ring 20 to rotate, and the second gear ring 20 drives the clamping plate 19 to rotate through the telescopic rod 21, thereby completing the turning operation of the blank. The first connecting plate 16 is fixed to the end of the screw 13 away from the clamping plate 19. The setting of the first connecting plate 16 facilitates the connection of the external drive device with the screw 13, thereby driving the screw 13 to rotate.

[0053] Reference Figure 2 , Figure 6 and Figure 7 In order to support and release the forging plate 8, a support structure is provided under the forging table 1 in this embodiment. The support structure includes a mounting plate 26 fixed to the bottom of the forging table 1, and the mounting plate 26 is located in the base 2. A plurality of support rods 48 are fixed to the bottom of the mounting plate 26, and the support rods 48 are fixed to the top of the base 2 for supporting the mounting plate 26. Two fixed columns 27 are fixed to the top of the mounting plate 26, and the two support columns 28 slide through the corresponding fixed columns 27 respectively. The outer wall of the support column 28 is provided with a second spring 30 fixedly connected to the bottom of the support plate 29, and the bottom end of the second spring 30 is fixedly connected to the top of the corresponding fixed column 27. The provision of the second spring 30 enables the support column 28 to move up and down when subjected to external force, and at the same time ensures that the support column 28 can be reset when not subjected to external force. The bottom ends of the two support columns 28 slide and extend to the bottom of the mounting plate 26, and the two support columns 28 are provided with a plurality of pin holes 31, and the pin holes 31 are located below the mounting plate 26.

[0054] When the support column 28 needs to be braked, the pin rod 34 can be inserted into the pin hole 31 to achieve the braking of the support column 28. At this time, the support column 28 cooperates with the support plate 29 to support the forging plate 8. When the support for the forging plate 8 needs to be released, the pin rod 34 can be pulled out to release the brake on the support column 28. At this time, the support column 28 moves upward under the action of the second spring 30, and the support for the forging plate 8 is simultaneously released, which is convenient for the later turning over of the blank.

[0055] Reference Figure 3 , Figure 5 and Figure 8 In addition, in this embodiment, a hydraulic structure is also arranged below the rotating ring 10 and the forging table 1, which is used to control the operation of the supporting structure when the supporting structure is in operation. The hydraulic structure mainly includes two cavities 23 arranged in the rotating ring 10. The first piston plate 24 is sealed and slidably connected in both cavities 23. The function of the first piston plate 24 is to move under the push of hydraulic oil, thereby transmitting hydraulic power. Push rods 25 are fixed on the sides away from each other of the two first piston plates 24, and one end of these push rods 25 is sealed and slidably penetrates the inner wall of one side of the cavity 23 and extends to one side of the gantry 3. Furthermore, the ends of the two push rods 25 away from each other are fixedly connected to the corresponding first connecting plates 16 respectively. In this way, when the screw rod 13 moves on the gantry 3 through the threaded connection, it will drive the first piston plate 24 to move through the first connecting plate 16.

[0056] Reference Figure 6-Figure 8 At the bottom of the mounting plate 26, a hydraulic box 32 is fixed. The bottom of the hydraulic box 32 is rotatably connected to a connected rotating tube, and a U-shaped tube 35 is fixed to the bottom end of the rotating tube. The two ends of the U-shaped tube 35 are fixedly connected to the two cavities 23 respectively. When the two first piston plates 24 move toward the middle, they will draw the hydraulic oil from the hydraulic box 32 into the cavity 23 through the U-shaped tube 35. In the hydraulic box 32, two second piston plates 33 are sealed and slidably connected, and the two second piston plates 33 are located on both sides of the rotating tube. A plurality of pins 34 are fixed to the sides of the two second piston plates 33 that are away from each other, and one end of these pins 34 passes through the inner wall of one side of the hydraulic box 32 and extends to one side of the hydraulic box 32. The pins 34 cooperate with the pin holes 31 set on the support column 28 to brake the forging plate 8.

[0057] Specifically, when the screw rod 13 synchronously drives the push rod 25 and the first piston plate 24 to move through the first connecting plate 16, the first piston plate 24 slides in a sealed manner in the cavity 23, and the hydraulic oil in the hydraulic box 32 is pumped into the cavity 23 through the U-shaped tube 35. At this time, the second piston plate 33 and the pin rod 34 will move toward the middle under the action of the hydraulic oil, and the pin rod 34 will be separated from the pin hole 31, thereby releasing the brake on the support column 28, and at the same time releasing the support of the support column 28 on the forging plate 8, so as to facilitate the later turning over of the blank. Conversely, when the forging plate 8 needs to be fixed, the pin rod 34 will be inserted into the pin hole 31 to brake the support column 28, thereby supporting the forging plate 8.

[0058] Reference Figure 5 and Figure 6 In addition, two fixed shafts 7 are fixed in the through hole 6, and two forging plates 8 are rotatably sleeved on the outer walls of the corresponding fixed shafts 7. In order to drive the forging plates 8 to reset and provide driving force for the blanks carried by the forging plates 8, two torsion springs 9 are sleeved on the outer walls of the two fixed shafts 7. The ends of the two torsion springs 9 that are close to each other are fixedly connected to one side of the forging plate 8, respectively, and the ends of the two torsion springs 9 that are far away from each other are fixedly connected to the inner wall of one side of the corresponding through hole 6.

[0059] Reference Figure 6 The design of the forging plate 8 also takes into account its rotation and reset functions. The bottom of the two forging plates 8 that are away from each other are provided with a curved surface, which makes it easier for the forging plates 8 to rotate when under pressure. The top of the two forging plates 8 that are away from each other are provided with a right-angled surface, which is used to limit the reset rotation of the forging plates 8, so that the forging plates 8 can maintain a horizontal position when resetting.

[0060] Reference Figure 3 and Figure 4 Finally, the telescopic rod 21 is composed of an inner rod and an outer rod, and the inner rod can slide and extend to the inside of the outer rod. Such a design enables the second gear ring 20 to drive the clamping plate 19 to rotate through the telescopic rod 21, thereby achieving the clamping and release of the blank.

[0061] Reference Figure 1 The top of the forging table 1 is rotatably connected to a cylinder 11, which is used to provide power to drive the rotation of the rotating ring 10. In order to achieve the connection between the cylinder 11 and the rotating ring 10, a rotating pin is fixed on one side of the top of the rotating ring 10, and the output shaft of the cylinder 11 is rotatably connected to the rotating pin. In this way, when the cylinder 11 is working, the telescopic action of its output shaft will be converted into the rotation action of the rotating ring 10 through the rotating pin.

[0062] Reference Figure 5Two arc grooves 36 are also provided inside the forging table 1. The positions of the two arc grooves 36 correspond to the top of the U-shaped tube 35. When the U-shaped tube 35 rotates with the rotation of the rotating ring 10, the arc grooves 36 provide necessary space for the rotation of the U-shaped tube 35 to avoid obstruction.

[0063] Reference Figure 8 and Fig. 9 Furthermore, a plurality of sliding grooves 37 are provided at the bottom of the rotating ring 10, and a trapezoidal plate 39 is slidably connected in each of the sliding grooves 37. The trapezoidal plate 39 is designed to push the oxide layer separated from the outer wall of the blank on the forging table 1 to the forging plate 8 when the rotating ring 10 rotates. To achieve this, the inclined surface of the trapezoidal plate 39 will contact the blank on the forging table 1 as the rotating ring 10 rotates, thereby pushing the oxide layer to the forging plate 8.

[0064] Reference Fig. 9 In order to maintain the stability of the trapezoidal plate 39 in the sliding groove 37 and allow it to have a certain amount of movement space when subjected to external force, a sliding rod 38 is fixed on one side of each trapezoidal plate 39, and the sliding rod 38 will slide through the inner wall of one side of the sliding groove 37 and extend to one side of the rotating ring 10. In addition, a tension spring 40 is sleeved on the outer wall of the sliding rod 38, one end of the tension spring 40 is fixedly connected to the outer wall of the rotating ring 10, and the other end is fixedly connected to the outer wall of the sliding rod 38. In this way, when the trapezoidal plate 39 is subjected to external force, it will move along the sliding groove 37, and the tension spring 40 will be stretched or compressed, providing the necessary elasticity and buffer for the movement of the trapezoidal plate 39.

[0065] During the forging process, the oxide layer on the blank will fall off and fall onto the forging table 1. At this time, the cylinder 11 will drive the rotating ring 10 to rotate, and the rotating ring 10 will push the oxide layer toward the forging plate 8 through the trapezoidal plate 39. When the forging plate 8 is squeezed by the blank and rotates, it will push the trapezoidal support block 44 downward, and drive the guide plate 41 to rotate through the connecting rod 47 and the push block 42. Finally, the oxide layer will fall from the guide plate 41 into the collection box 49. The whole process realizes the automatic cleaning and collection of the oxide layer, greatly improving the production efficiency and product quality.

[0066] Through the design of the above structure, the automatic forging and forming machine for processing hardware blanks can realize operations such as automatic clamping, forging and turning over of the blanks, thereby greatly improving production efficiency and product quality.

[0067] Example 2: Reference Figure 10-12, improved on the basis of Example 1: the top of the mounting plate 26 is also rotatably connected to a guide plate 41, which is located between the two fixed columns 27 and is used to guide the oxide layer falling from the forging plate 8. In order to cooperate with the work of the guide plate 41, a vertical rod 43 is also fixed to the bottom of the forging table 1, and a trapezoidal support block 44 is slidably sleeved on the outer wall of the vertical rod 43, and the trapezoidal support block 44 is located below the two forging plates 8. A third spring 45 is also sleeved on the outer wall of the vertical rod 43, and the top end of the third spring 45 is fixedly connected to the bottom of the trapezoidal support block 44, and the bottom end is fixedly connected to the outer wall of the vertical rod 43. In this way, when the forging plate 8 is squeezed by the blank and rotates, it will push the trapezoidal support block 44 downward and compress the third spring 45 at the same time.

[0068] Two second connecting plates 46 are fixed to both sides of the bottom of the trapezoidal support block 44, and one side of each of the two second connecting plates 46 is rotatably connected to a connecting rod 47. The bottom end of the connecting rod 47 is rotatably connected to a push block 42, and the push block 42 is slidably mounted on the top of the mounting plate 26. When the trapezoidal support block 44 moves downward, it pushes the push block 42 to move to one side through the second connecting plates 46 and the connecting rod 47. The top of the push block 42 touches the bottom of the guide plate 41, so the movement of the push block 42 drives the guide plate 41 to rotate.

[0069] A collection box 49 is also placed on the top of the base 2, and the function of this collection box 49 is to receive the oxide layer falling from the guide plate 41. When the guide plate 41 rotates to a certain angle, the oxide layer accumulated thereon will fall into the collection box 49, thereby facilitating subsequent cleaning and processing.

[0070] A method for using an automatic forging machine for processing hardware blanks comprises the following steps:

[0071] S1. Place the heated blank on top of the two forging plates 8, and drive the forging hammer 5 through the hydraulic cylinder 4 to forge the blank. When the forging surface needs to be replaced, the first gear 15 is driven by the motor to rotate, and the first gear 15 drives the first gear ring 14 to rotate. The first gear ring 14 cooperates with the screw 13 to push the screw 13 to move. The screw 13 drives the push rod 18 and the clamping plate 19 to move toward the middle through the first spring 17 to clamp the blank.

[0072] S2. When the screw 13 clamps the blank toward the middle, the screw 13 synchronously drives the push rod 25 and the first piston plate 24 to move through the first connecting plate 16. The first piston plate 24 slides in a sealed manner in the cavity 23, and the hydraulic oil in the hydraulic box 32 can be pumped into the cavity 23 through the U-shaped tube 35. The second piston plate 33 and the pin rod 34 move toward the middle under the action of the hydraulic oil, and the pin rod 34 disengages from the pin hole 31, releasing the brake on the support column 28, and at the same time releasing the support of the support column 28 on the forging plate 8, so as to facilitate the later turning over of the blank;

[0073] S3, when turning over the blank, the second gear 22 is driven by the motor to rotate, the second gear 22 drives the second gear ring 20 to rotate, and the second gear ring 20 drives the clamping plate 19 to rotate through the telescopic rod 21, thereby completing the turning over of the blank, and the blank is turned over to its right angle edge to push the two forging plates 8 to rotate. When the blank is turned over, the forging plate 8 is reset under the action of the torsion spring 9 and supports the blank thereon, and the screw 13 drives the clamping plate 19 to move outward to release the clamping of the blank. At this time, the first connecting plate 16 drives the first piston plate 24 to reset, and the pin rod 34 is reinserted into the pin hole 31. The support plate 29 moves up and resets under the action of the second spring 30 to support the forging plate 8 again, and the cooperation of the first piston plate 24 and the pin hole 31 brakes the support column 28;

[0074] S4, when the surface clamped by the two clamping plates 19 is forged, the output shaft of the cylinder 11 contracts and drives the rotating ring 10 to rotate 90 degrees counterclockwise, and the rotating ring 10 drives the fixed platform 12 and the U-shaped tube 35 to rotate synchronously. At this time, the clamping plates 19 can clamp the corresponding blank surface, and then repeat step S2 to turn the blank over, so as to forge the previously unforged surface;

[0075] S5. During the forging process, the oxide layer on the blank falls off, and when the cylinder 11 drives the rotating ring 10 to rotate, the trapezoidal plate 39 can guide the oxide layer on the forging table 1 to the forging plate 8 through the inclined surface of the trapezoidal plate 39, and the cooperation of the tension spring 40 and the sliding rod 38 can make the trapezoidal plate 39 touch the blank to make way;

[0076] S6. During the forging process, the oxide layer on the blank falls off and accumulates on the forging plate 8. When the forging plate 8 is turned over, the right-angled edge of the blank pushes the two forging plates 8 to rotate. At this time, the oxide layer falls onto the guide plate 41 under the action of the forging plate 8, and the forging plate 8 pushes the trapezoidal support block 44 and the second connecting plate 46 to move downward when the forging plate 8 rotates. The second connecting plate 46 pushes the push block 42 to one side through the connecting rod 47. The push block 42 drives the guide plate 41 to rotate, and the oxide layer accumulated on the guide plate 41 can be easily poured into the collection box 49.
