Description

Technical Field

[0001] The invention relates to the technical field of forging equipment, and in particular to a forging positioning tool and a positioning method thereof for producing automobile hardware. Background Art

[0002] Forging is a processing process. Forging is an object that is formed into a required shape or suitable compression force by plastic deformation under pressure. Forging is a processing method that uses a forging machine to apply pressure to a metal blank to cause it to undergo plastic deformation to obtain a forging with certain mechanical properties, shape and size. Forging can eliminate defects such as loose cast state produced during the metal smelting process, optimize the microstructure, and at the same time, because the complete metal flow lines are preserved, the mechanical properties of forgings are generally better than those of castings of the same material. Forgings require that each piece is consistent, without any porosity, inclusions or other defects. The components produced by this method have a high strength-to-weight ratio. The advantages of forgings include extendable length; retractable length, extendable cross-section; changeable length, changeable cross-section.

[0003] Referring to the Chinese invention patent, publication number: CN 113441671 A, title: Forging positioning tooling for automobile hardware production, this invention patent adopts a variable chuck structure, and uses a chuck cavity box filled with electrorheological fluid to clamp the forging parts. During the forging process, the liquid-solid conversion of the chuck cavity box is controlled by the power-on voltage of the electrorheological fluid to change the hardness of the chuck cavity box. During the forging impact process, liquid electrorheological fluid is used for buffering to avoid forging impact vibration and lateral expansion movement of the forging parts. Damage to the positioning mechanism caused by the movement.

[0004] However, in actual use, the above technical solutions and similar technical solutions still have some problems:

[0005] 1. This type of clamping and positioning tooling design has the limitation of single operation, that is, it can only clamp a single workpiece at a time. This feature requires operators to frequently approach the working area during the removal and placement of the workpiece, increasing the risk of direct exposure to potential dangers. Especially when the stamping end is in an active state, if there is a lack of effective safety protection measures, it is very easy to cause injuries to workers, posing a serious threat to operational safety;

[0006] 2. This clamping tool adopts an electric control system to realize the workpiece clamping operation. However, during the stamping operation, the high-speed collision between the mold and the workpiece will produce a significant vibration effect. This strong physical vibration may not only affect the stability of the clamping tool, but also easily cause physical damage or performance degradation to the precise electrical components inside the clamp, thereby affecting the reliability and service life of the entire control system;

[0007] 3. In the stamping and forging process, in order to improve the lubricity and separation effect between the die and the workpiece, it is usually necessary to spray a release agent. However, some release agent ingredients contain chemical substances that are harmful to the human body. These substances are easily vaporized under high temperature conditions and diffuse into the air of the working environment. The diffusion of such harmful gases not only pollutes the air quality at the work site, but may also be inhaled by workers through the respiratory tract and other pathways. Long-term exposure will seriously threaten the health of workers and increase the risk of occupational diseases. Summary of the invention

A connected exhaust pipe is installed on the airbag. The top end of the airbag is connected to a one-way door for one-way air intake.

[0021] The positioning method of a forging positioning tool for automobile hardware production comprises the following steps:

[0022] S1. The positioning bridge is installed above the anvil. The heated metal block to be forged is placed on the sliding frame on one side of the positioning bridge. The electric push rod pushes the first rack to move, the gear segment rotates, and drives a pair of telescopic rods to rotate. The sliding frame on the driving side drives the metal block to move downward to the stamping end. The stamped and forged metal block is pushed out, and the new metal block will be automatically loaded;

[0023] S2, the sliding frame slides along the positioning bridge through the contact wheel, and the first gear pushes a pair of second racks on both sides to move synchronously, driving the clamp to automatically clamp and fix the metal block, turning the knob to push the slider to slide, adjusting the distance between the clamp and the push block, and clamping and positioning different metal blocks;

[0024] S3. When the stamping end is stamping, the first fixed frame moves downward, the cloth blocks the heat loss of the metal block and the splashing of debris, and the nozzle sprays the release agent onto the mold of the stamping end. When the stamping end moves downward, the exhaust gas is squeezed, and the lifting rod drives the airbag to expand downward. The exhaust gas inside the cloth is sucked into the airbag and discharged and collected through the one-way valve and the exhaust pipe.

[0025] Compared with the prior art, the present invention provides a forging and positioning tool for automobile hardware production, which has the following beneficial effects:

[0026] 1. The forging positioning tooling for automobile hardware production uses an electric push rod to push the first rack to move, and the first rack drives the gear segment to rotate, thereby driving a pair of telescopic rods to rotate. The sliding frame on one side drives the metal block to move below the stamping end, and the telescopic rod shrinks. The sliding frame originally located below the stamping end will drive the stamped and forged metal block to move to the other side of the positioning bridge, thereby realizing the rapid push-out of the stamped and forged metal block, and the new metal block will be automatically loaded, which is convenient for the stamping and forging of the metal block and improves work efficiency.

[0027] 2. The forging positioning tooling for automobile hardware production slides along the positioning bridge through the resistance wheel. Since the positioning bridge is in a "><"-shaped structure, the resistance wheel will be pushed. When the resistance wheel moves toward the sliding frame, it pushes the second rack to slide, and through the first gear transmission, the pair of second racks on both sides move synchronously, so that the sliding frame is still located in the middle position and will not shift. The second rack pushes the slide cylinder, and under the action of the second spring, it drives the slide rod to move, thereby pushing the push block and driving the clamp to automatically clamp and position the metal block, so as to facilitate its transfer to the anvil, so as to facilitate stamping and forging through the stamping end, automatic clamping and release, and easy operation.

[0028] 3. The forging positioning tooling for automobile hardware production, when stamping at the stamping end, the cloth can effectively slow down the heat loss of the metal block and prevent debris from splashing. When the stamping end moves upward, the release agent is sprayed onto the mold of the stamping end through the air intake pipe and the nozzle. The diffused release agent will be restricted by the cloth to prevent diffusion. At the same time, when the stamping end moves downward, the exhaust gas is squeezed, and the airbag is driven to expand downward through the support rod, so that the exhaust gas inside the cloth is sucked into the airbag. The stamping end moves upward, driving the airbag to compress, and the one-way door is closed, so that the inhaled gas is discharged through the one-way valve and the exhaust pipe, and then centrally processed to avoid environmental pollution.

A lifting rod 44 is installed on the first fixed frame 42. The lifting rod 44 and the second fixed frame 43 are connected. Sliding connection, a third spring 45 is installed between the lifting rod 44 and the second fixed frame 43, a demoulding mechanism 5 is connected to the anvil 1, the demoulding mechanism 5 includes an airbag 55, both sides of the anvil 1 are connected with airbags 55, the bottom end of the airbag 55 is connected to the lifting rod 44, a connected exhaust pipe 53 is installed on the airbag 55, the top end of the airbag 55 is connected to a one-way door 57 for one-way air intake, a nozzle 59 is installed on the inner side of the first fixed frame 42, so as to facilitate the exhaust gas to be drawn into the airbag 55, the nozzle 59 can spray the demoulding agent.

[0052] In the present invention, a fixing box 51 is installed on both sides of the anvil 1, and an airbag 55 is arranged inside the fixing box 51.

[0054] Working principle: the positioning bridge 31 is installed above the anvil 1, and the two sliding frames 33 are respectively located on one side of the positioning bridge 31 and above the anvil 1, and the heated metal block to be forged is placed on the sliding frame 33 on one side of the positioning bridge 31, and the bottom end of the metal block contacts the support plate 7, and the metal block is located between a pair of clamps 375 and is fixed by the clamps 375. During forging, the electric push rod 323 is started to push the first rack 322 to move, and the first rack 322 drives the gear segment 324 to rotate, thereby driving a pair of telescopic rods 321 to rotate, and the sliding frame 33 on one side drives the metal block to move below the stamping end 2, and the telescopic rod 321 contracts. The sliding frame 33 originally located below the stamping end 2 will drive the stamped and forged metal block to move to the other side of the positioning bridge 31, thereby realizing the rapid push-out of the stamped and forged metal block, and the new metal block will be automatically loaded, thereby facilitating the stamping and forging of the metal block and improving work efficiency;

[0055] When the sliding frame 33 on one side of the positioning bridge 31 is pushed by the telescopic rod 321 to load the material, the sliding frame 33 will slide along the positioning bridge 31 through the contact wheel 36. Since the positioning bridge 31 is in a "><"-shaped structure, the contact wheel 36 will be pushed. When the contact wheel 36 moves toward the sliding frame 33, it pushes the second rack 35 to slide, and is transmitted through the first gear 38, so that the pair of second racks 35 on both sides move synchronously, so that the sliding frame 33 is still located in the middle position and will not deviate. The second rack 35 pushes the slide cylinder 391, and under the action of the second spring 393, the slide rod 392 is driven to move, thereby pushing the push block 34, and driving the clamp 375 to automatically move the metal block. Dynamic clamping and positioning, so as to facilitate its transfer to the anvil 1, so as to facilitate stamping and forging through the stamping end 2. During stamping, the mounting block 371 and the clamp 375 will move down with the metal block, the first spring 373 will be compressed, and the lower end of the metal block will contact the surface of the anvil 1, so as to facilitate forging and avoid misalignment of the metal block and the clamp 375. When clamping metal blocks of different specifications, the knob 374 is turned to push the slider 372 to slide, so as to facilitate adjustment of the distance between the clamp 375 and the push block 34, so as to facilitate adaptation to different metal blocks. At the same time, the clamp 375 can be disassembled by a wrench, so as to facilitate replacement of clamps 375 of different specifications, so as to achieve automatic clamping and release, and easy operation;

[0056] When the punching end 2 is punching, the punching end 2 contacts the first fixed frame 42, thereby pushing the first fixed frame 42 to move downward, the lifting rod 44 slides downward, and the third spring 45 is stretched. During the punching process, the surrounding cloth 41 can effectively slow down the heat loss of the metal block and prevent debris from splashing. When the punching end 2 moves upward, the release agent is sprayed onto the mold of the punching end 2 through the air inlet pipe 52 and the nozzle 59. The diffused release agent will be restricted by the surrounding cloth 41 to prevent diffusion. At the same time, when the punching end 2 moves downward, the exhaust gas is squeezed, and the lifting rod 44 moves downward. The airbag 55 is driven to expand downward through the support rod 58, thereby forming a negative pressure inside the airbag 55, causing the one-way door 57 to rotate toward the inside of the fixed box 51, and the torsion spring 8 is compressed, thereby sucking the exhaust gas inside the surrounding cloth 41 into the airbag 55. The stamping end 2 moves upward, driving the airbag 55 to compress, and the one-way door 57 is closed, thereby discharging the sucked gas through the one-way valve 56 and the exhaust pipe 53, and then centrally processing it to avoid polluting the environment. When the sliding frame 33 slides, it pushes the telescopic frame 54 to move downward, and the fourth spring 6 is compressed, thereby avoiding affecting the movement of the sliding frame 33.
