Description

Technical Field

[0001] The invention relates to the field of metal processing, and more particularly to an automatic forging production line. Background Art

[0002] Forging is the process of heating, upsetting, punching and expanding a metal billet of a certain length. Among them, heating and upsetting are primary processing. The metal billet is sent to a heating furnace for heating, and then the heated metal billet is upset. The upsetting operation is done manually, and forging is also done by a hydraulic press. The use of a hydraulic press can liberate labor and is more efficient. Therefore, corresponding equipment has emerged for the forging process to form a forging production line.

[0003] The manual forging production line is a traditional forging processing technology. Although the technology is mature, the efficiency is low. With the demand for industrialized production, the manual forging production line cannot meet the needs of large-scale production. During forging work, employees work in an environment of high temperature, dust, noise, etc., which is dangerous.

[0004] The Chinese patent with authorization announcement number: CN110421105B discloses a forging production line that can perform preliminary processing on metal billets. An automatic loading device is provided to realize the automation of loading the heating furnace. The material heated in the heating furnace is automatically transported to the hydraulic press for upsetting processing through an automatic discharging device, thereby freeing up labor.

[0005] When the metal billet is heated in an electric furnace, the surface of the metal billet reacts with oxygen in the air at high temperature to form a brittle and fragile oxide scale. Due to the brittleness of the oxide scale, when it is subjected to external force, the bond between the oxide scale and the metal matrix will be destroyed, resulting in the shedding of the oxide scale. Especially at high temperatures, the expansion coefficients of the metal and the oxide scale are inconsistent, and this difference will aggravate the tendency of the oxide scale to fall off.

[0006] The above patent still has the following shortcomings: when the metal blank is clamped by the robotic arm, if the oxide scale falls off or breaks, the surface of the metal blank will lose part of its support, causing the blank to lose balance. Therefore, in the process of transferring the heated blank to the next process by clamping, there is a risk of falling, which is dangerous.

[0007] Therefore, a forging automated production line is proposed. Summary of the invention

[0053] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0054] Embodiment 1:

[0055] See also Figures 1 to 11 , an automatic forging production line, comprising an electric furnace 1 and a roll forging machine 2;

[0056] It includes a gantry 3, a combined guide rail 4, and a telescopic rod 5. The combined guide rail 4 is used to drive the telescopic rod 5 to move. The gantry 3 is located between the electric furnace 1 and the roll forging machine 2. The combined guide rail 4 is installed on the gantry 3. The combined guide rail 4 includes a first electric guide rail 401 and a second electric guide rail 402. The second electric guide rail 402 is installed on the gantry 3. The first electric guide rail 401 is installed on the output end of the second electric guide rail 402. The telescopic rod 5 is installed on the output end of the first electric guide rail 401.

[0057] Also includes:

[0058] The clamping mechanism comprises a housing 6, a clamping plate 7, and a first driving assembly; the housing 6 is arranged on the output end of the telescopic rod 5, the clamping plate 7 is slidably installed in the housing 6, the clamping plate 7 is used to clamp the workpiece, and the first driving assembly is used to drive the clamping plate 7 to move;

[0059] The lifting mechanism includes a sleeve 8, an insertion rod 9, a support rod 10, a rotating assembly, a bayonet 11, and a second driving assembly; the sleeve 8 is used to install the insertion rod 9, the bayonet 11 is used to receive the support rod 10, the rotating assembly is used to rotate the support rod 10 to the bottom of the workpiece, the support rod 10 is used to support the workpiece, and the second driving assembly is used to drive the support rod 10 to extend from the bayonet 11;

[0060] The cleaning mechanism comprises a cavity 12, an air hole 13 and an air supply assembly; the air supply assembly is used to provide air to the cavity 12, and the air discharged from the air hole 13 is used to clean impurities on the surface of the clamping plate 7;

[0061] Among them, first, the shell 6 moves to the specified position, and then the first driving component drives the clamping plate 7 to move to clamp the workpiece and start feeding the roll forging machine 2. At the same time, the second driving component cooperates with the rotating component, and the support rod 10 moves to the bottom of the workpiece to prevent the workpiece from falling.

[0062] There are two splints 7, and the first driving assembly includes a stepper motor 14 arranged on the shell 6. A bidirectional threaded rod 15 is installed on the output end of the stepper motor 14. The two splints 7 are symmetrically threadedly installed on the bidirectional threaded rod 15. A control module 16 cooperating with the stepper motor 14 is provided on the gantry 3, and the control module 16 also controls the operation of the combined guide rail 4 and the telescopic rod 5.

[0063] The rotating assembly includes an inclined groove 17 provided on the inner wall of the sleeve 8, a slider 18 is slidably installed in the inclined groove 17, the slider 18 is fixedly connected to the insertion rod 9, and an internal elastic member 19 is rotatably installed between the insertion rod 9 and the inner top wall of the sleeve 8.

[0064] The second driving assembly includes a socket 20 opened on the bottom wall of the clamping plate 7, the sleeve 8 is slidably inserted in the socket 20, and an external elastic member 21 is provided between the sleeve 8 and the top wall of the socket 20; an extension rod 22 is fixedly installed on the bottom wall of the sleeve 8.

[0065] First, the raw materials are transported to the automatic loader of the production line by an unmanned automatic guided transport vehicle. The automatic guided transport vehicle and the automatic loader are prior art and will not be described in detail. The automatic loader automatically pushes the raw materials into the electric furnace 1 in sequence according to a set program, and the raw materials are heated by induction in the electric furnace 1. Then, the heated workpiece can be transferred to the roll forging machine 2 for processing.

[0066] Then the control module 16 controls the first electric guide rail 401 and the second electric guide rail 402 to work, so as to drive the telescopic rod 5 to move, and the extension of the telescopic rod 5 can drive the housing 6 and the clamping plate 7 to move.

[0067] When the bottom wall of the extension rod 22 is not subject to resistance, the sleeve 8 is in a state of extending from the insertion hole 20 under the action of the external elastic member 21; under the action of the internal elastic member 19, the slider 18 is located at the top of the inclined groove 17, at which time the insertion rod 9 is in a state of extending from the sleeve 8, and the support rod 10 is perpendicular to the side wall of the clamping plate 7;

[0068] When the housing 6 moves downward and the extension rod 22 encounters resistance, the extension rod 22 pushes the sleeve 8 upward, and at this time the outer elastic member 21 is squeezed. Since the cross section of the sleeve 8 is a polygon, it can limit the moving direction of the sleeve 8. Therefore, during the upward movement of the sleeve 8, under the action of the inclined surface of the side wall of the inclined groove 17, the slider 18 will move along the inclined groove 17. At this time, the insertion rod 9 rotates, and the inner elastic member 19 is stretched. At the same time, the support rod 10 rotates together until the support rod 10 is at the projection position of the bayonet 11. At this time, the slider 18 is located at the bottom end of the inclined groove 17, and the bottom end surface of the extension rod 22 is parallel to the bottom wall of the support rod 10.

[0069] Then the shell 6 continues to move downward, at this time the extension rod 22 and the insertion rod 9 are both pushed upward, so that the support rod 10 and the extension rod 22 can be driven to enter the bayonet 11 together, and the bottom wall of the clamping plate 7 can contact the surface of the output end of the electric furnace 1, and then the clamping plate 7 is slid on the surface of the output end of the electric furnace 1 until the workpiece is located between the two clamping plates 7, and then the control module 16 controls the stepping motor 14 to rotate the number of circles, the number of circles here is determined by the size of the workpiece, which is the prior art and will not be repeated; thereby, the two clamping plates 7 on the bidirectional threaded rod 15 can be brought close to each other, and at this time the clamping plates 7 clamps the workpiece, and then the telescopic rod 5 contracts. At this time, the pressure on the outer elastic member 21 is reduced, so the sleeve 8 extends from the insertion hole 20 and drives the support rod 10 to move until the top wall of the support rod 10 and the bottom wall of the clamping plate 7 are in the same plane. At the same time, the internal elastic member 19 recovers and pulls the insertion rod 9 to move. At this time, under the action of the slider 18 and the inclined groove 17, the support rod 10 can be driven to reverse through the insertion rod 9 until the support rod 10 moves to the bottom of the workpiece clamped by the clamping plate 7, thereby preventing the workpiece from falling during the clamping and transportation process, thereby improving the safety.

[0070] When the support rod 10 rotates on the bottom wall of the workpiece, the metal scraper on the support rod 10 moves on the surface of the workpiece, so as to clean off part of the oxide scale on the surface of the workpiece, thereby reducing the content of oxide scale on the surface of the forging in the subsequent roll forging process, thereby improving the forging effect.

[0071] Then align the workpiece with the feed port of the roll forging machine 2, and then feed it into the roll forging machine 2 through the feed port. The roll forging machine 2 forges the workpiece into a profiled blank through continuous rolling action. The profiled blank is automatically transmitted to the press brake, and is bent in the press brake to become a semi-circular hook semi-finished product, and placed at a fixed point for the robot arm to clamp. Then the robot arm clamps the semi-finished product and puts it into the fixed point of the press. The semi-finished product is forged in the press to form the final product shape. The forged finished product is manually placed in the fixed point clamping position of the next robot arm. After the forged finished product is placed in the fixed point clamping position, it is clamped by another robot arm and placed in the trimming machine for trimming to remove excess burrs. After trimming is completed, the finished product is pushed into the material basket by the cylinder, and the burrs are pushed into the waste basket to achieve automatic separation of the finished product and the waste. Among them, the press brake, the robot arm, the press, the trimming machine, the material frame and the waste basket are all processes in the forging automation production line, and are prior art, so they will not be repeated.

[0072] like Figure 3 , Figure 4 As shown, the clamping plate 7 includes a driving rod 701, a connecting rod 702 and a cross plate 703. A threaded hole is provided on the driving rod 701. The driving rod 701 is threadedly mounted on the bidirectional threaded rod 15 through the threaded hole. The driving rod 701 and the bidirectional threaded rod 15 are both arranged in the hollow shell 6. Therefore, under the restriction of the inner top wall and the inner bottom wall of the shell 6, the driving rod 701 can move along the bidirectional threaded rod 15 during the rotation of the bidirectional threaded rod 15 without rotating with the bidirectional threaded rod 15. The connecting rod 702 and the cross plate 703 are respectively mounted at both ends of the driving rod 701, and the driving rod 701 and the cross plate 703 are distributed on both sides of the connecting rod 702.

[0073] The cavity 12 is formed on the connecting rod 702 , and the air holes 13 are evenly formed on the side wall of the cavity 12 close to the horizontal plate 703 , and the air holes 13 are inclined in a horizontal plane.

[0074] The outer elastic member 21 is a metal airbag, and a spring 23 is arranged inside the metal airbag. The spring 23 is used to restore the metal airbag.

[0075] The air supply assembly includes an air pipe 24 inserted into the outer elastic member 21 , and one end of the air pipe 24 away from the outer elastic member 21 extends into the cavity 12 .

[0076] By adopting the above technical solution, when the sleeve 8 moves upward, the outer elastic member 21 is squeezed, so the gas in the outer elastic member 21 flows along the air pipe 24 into the cavity 12 and is finally discharged through the air hole 13 .

[0077] The gas discharged from the evenly and obliquely arranged air holes 13 impacts the surface of the horizontal plate 703, thereby knocking off the oxide scale and other solid impurities attached to the surface of the horizontal plate 703. When the clamping plate 7 clamps the workpiece, the impurity content between the side wall of the horizontal plate 703 and the workpiece is reduced, ensuring that there is sufficient friction between the clamping plate 7 and the workpiece, thereby preventing the workpiece from falling, thereby further improving safety.

[0078] Among them, metal airbags are existing technology and will not be described in detail.

[0079] like Figure 6 As shown, by adopting the above technical solution, a filter screen 25 is embedded on the side wall of the cavity 12 , and the filter screen 25 covers the surface of the pore 13 .

[0080] During the recovery process of the outer elastic member 21, the outer elastic member 21 absorbs air through the air hole 13, so some solid particles around the air hole 13 will be sucked into the air hole 13. At this time, the filter screen 25 can filter the solid impurities, thereby protecting the outer elastic member 21.

[0081] Since the filter 25 is located on the inner wall of the cavity 12, the filtered particles will gather in the pores 13. When the outer elastic member 21 is squeezed and exhausted, the particles in the pores 13 will be flushed out by the airflow. At this time, the particles moving with the airflow impact the surface of the splint 7, which can knock down the impurities attached to the surface of the splint 7 and generate an impact force on the splint 7, shaking off the impurities on the surface of the splint 7, thereby improving the cleaning effect of the splint 7.

[0082] like Figure 1 As shown, by adopting the above technical solution, a transfer basket 26 is also included, and a temperature detection module 27 and a comparison module 28 are provided on the electric furnace 1;

[0083] The temperature detection module 27 is used to detect the temperature of the workpiece heated by the electric furnace 1 and send the detected data to the comparison module 28;

[0084] The comparison module 28 stores the standard value of the temperature that the heated workpiece should reach. The comparison module 28 is used to compare the received data with the stored data and send the ratio to the control module 16;

[0085] The control module 16 is used to control the movement of the output end of the combined guide rail 4:

[0086] Transferring workpieces that do not reach the temperature standard value to the transfer basket 26;

[0087] The workpiece whose temperature reaches the specified temperature is transferred to the next processing step; finally, the roll forging machine 2 is provided with workpieces of qualified temperature, which plays a role in protecting the roll forging machine 2.

[0088] like Figure 1 , Fig.11 As shown, by adopting the above technical solution, the temperature detection module 27 is an infrared temperature probe, and the comparison module 28 compares the received data with the standard value:

[0089]

[0090] Where t is the actual temperature detected by the temperature detection module 27, and t0 is the standard temperature that the workpiece should reach;

[0091] When A≥1, the control module 16 controls the combined guide rail 4 to clamp the workpiece into the roll forging machine 2 for the next step of processing;

[0092] When A<1, the control module 16 controls the combined guide rail 4 to clamp the workpiece into the transfer basket 26 .

[0093] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
