Description

Technical Field

[0001] This invention belongs to the field of automotive parts forging technology, and particularly relates to a forging process and forging equipment for automotive parts blanks. Background Technology

[0002] Forging is a processing method that uses forging machinery to apply pressure to a metal billet, causing it to undergo plastic deformation to obtain forgings with certain mechanical properties, shapes, and dimensions. During the die forging process, parts are often subjected to reciprocating pressing. During this process, some slag is generated on the metal surface and splashes in all directions. At the same time, the forged metal will volatilize, releasing some harmful gases and metal particles.

[0003] A forging equipment for manufacturing and processing ship parts, with publication number CN115846577A, is equipped with a collection mechanism. When the forging hammer strikes the ship's drive shaft, the collection frame moves up and down with the operating table. Since rack one and rack two mesh, when the collection frame moves downward, the arc plate drives the baffle to rotate, causing the end of the baffle near rack two to rotate downward. The through hole on one side of the cavity is aligned with the top of the operating table, and the baffle and the air hole are misaligned. The suction fan runs, and the air near the through hole flows towards the through hole under the action of the suction fan. Therefore, the metal scrap generated during the forging process moves towards the through hole with the air, thus realizing the collection of metal scrap generated during the forging process.

[0004] In the above solution, during the forging of parts, the arc plate can only drive the baffle to rotate and rise to block the waste generated by hammering when the forging hammer contacts the part. This process has a lag, and the flying chips generated at the moment the forging hammer contacts the part cannot be collected in time. Moreover, when the forging hammer rises, the collection frame is prone to vibration of the part, causing the flying chips to fall. At this time, the baffle resets, and the blocking time is short. At the same time, the baffle rotates from horizontal to vertical, which limits the blocking height of the baffle. If the baffle is too long, the baffle occupies a lot of space. In addition, the surface temperature of the part is high during forging, which leads to the high temperature of the flying chips, which are easy to stick to everywhere when splashing and are not easy to collect with a suction fan.

[0005] To avoid the aforementioned technical problems, it is indeed necessary to provide a forging process and forging equipment for automotive parts blanks to overcome the deficiencies in the prior art. Summary of the Invention

[0006] The purpose of this invention is to provide a forging process and forging equipment for automotive parts blanks, aiming to solve the technical problem of limited dust collection effect during forging in the prior art.

[0007] This invention is implemented as follows: a forging device for automotive part blanks includes a worktable, wherein a forging press is fixedly connected to the worktable via a support frame, and further includes:

[0008] A protective cover is rotatably connected to the workbench. A shell is provided on one side of the protective cover, and a rotating sleeve is rotatably connected to the shell. A connecting plate is fixedly connected to the telescopic end of the forging press, and an elastic telescopic rod is fixedly connected to the connecting plate. A guide groove is spirally provided on the inner wall of the rotating sleeve. A sliding member is connected to the elastic telescopic rod, and the sliding member can move along the guide groove. A transmission assembly that drives the protective cover to rotate is provided between the rotating sleeve and the protective cover.

[0009] The protective cover is equipped with a spray pipe, and a scraper is fixedly connected to the outer wall of the spray pipe. The nozzle of the spray pipe faces the inner wall of the protective cover, and the scraper abuts against the inner wall of the protective cover. A water tank is fixedly connected to the worktable. One end of the elastic telescopic rod passes through the inside of the water tank. A pressure mechanism is provided in the water tank. When the elastic telescopic rod moves downward, the pressure mechanism can force water into the spray pipe. Multiple end holes communicating with the water tank are provided on the worktable inside the protective cover.

[0010] A cleaning plate is fitted into the inner wall of the protective cover. The cleaning plate is rotatably connected to the inner wall of the protective cover by an elastic torsion spring, and the cleaning plate is in contact with the end face of the workbench.

[0011] Further technical solution: The pressure mechanism includes an outer casing, a piston, a water pipe, a first check valve, and a second check valve;

[0012] The outer casing is fixedly connected to the inner end face of the water tank, the piston is fixedly connected to one end of the elastic telescopic rod, and the piston is slidably sealed to the inner end face of the outer casing. The water pipe is connected between the outer casing and the spray pipe. A first one-way valve is provided on the water pipe to guide the outer casing in one direction, and a second one-way valve is provided on the outer casing to guide the water tank in one direction.

[0013] A further technical solution: The transmission assembly includes a transmission wheel and a gear ring. The transmission wheel is fixedly connected to the rotating sleeve, and the gear ring is fixedly connected to the outer wall of the protective cover. The transmission wheel meshes with the gear ring.

[0014] A further technical solution: The scraper is composed of two straight plates with an included angle of less than 90 degrees, and both straight plates are in contact with the inner wall of the protective cover. Each of the two sides of one of the straight plates is provided with several through holes, the through holes on the two sides of the straight plate are interconnected, and the through holes on the two sides of the straight plate face the inner wall of the protective cover.

[0015] Further technical solution: Multiple turbine fans are fixedly connected to one end of the rotating sleeve inside the outer shell, and the outer shell is connected to the workbench by an air pipe. The other end of the air pipe is connected to the inside of the protective cover. An isolation mesh plate is provided at the end of the air pipe inside the protective cover, and an activated carbon adsorption plate is provided in the outer shell.

[0016] A further technical solution: A spring connects the rotating sleeve to the outer shell.

[0017] A further technical solution: the sliding element is a ball bearing.

[0018] A forging process for automotive part blanks, applied to forging equipment for the aforementioned automotive part blanks, includes the following steps:

[0019] Step S1: Place the cut raw material into the heating furnace and heat it;

[0020] Step S2: The heated raw material is conveyed to the positioning slot through the conveying device, and the forging press is started. The forging press performs reciprocating stamping and forging on the raw material.

[0021] During the forging process of the forging press on the raw material, when the forging press punch head moves downward, the connecting plate drives the elastic telescopic rod to move downward synchronously;

[0022] The sliding part on the elastic telescopic rod moves along the guide groove. Under the push of the sliding part, the rotating sleeve rotates. The rotating sleeve drives the protective cover to rotate through the transmission component. At this time, the cleaning plate cleans the flying debris on the worktable into the water tank through the end hole. At the same time, the scraper scrapes off the flying debris stuck to the inner wall of the protective cover. When the cleaning plate touches the scraper, the cleaning plate retracts into the inner wall of the protective cover under the push of the scraper.

[0023] The elastic telescopic rod pushes the pressure mechanism, which forces water into the nozzle, and the nozzle uses high-pressure water to further flush the inner wall of the protective cover.

[0024] When the forging press head is reset, the rotating sleeve drives the protective cover to rotate in the opposite direction through the transmission component, so that the scraper and cleaning plate scrape off the flying debris splashed inside the protective cover during this stamping and the water droplets attached to the protective cover. The falling flying debris enters the water tank through the end hole.

[0025] Step S3: Remove the forged blank material from the positioning groove.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] 1. A forging equipment for automotive parts blanks, wherein the elastic telescopic rod can elastically contract to reduce the instantaneous impact force of the forging press on the blank material, and avoid the splashing of the blank material slag. At the same time, under the action of water pressure in the pressure mechanism, the buffering effect on the forging press is further increased; thus, the splashing of the blank material slag is prevented before the forging press contacts it.

[0028] 2. A forging equipment for automotive parts blanks, wherein the protective cover rotates, the cleaning plate cleans the flying debris on the worktable through the end hole into the water tank, and at the same time the scraper scrapes off the flying debris adhering to the inner wall of the protective cover.

[0029] 3. A forging equipment for automotive parts blanks, wherein in the pressure mechanism, water flow in the nozzle washes the inner wall of the protective cover, cleaning the surface of the protective cover while cooling the inner wall of the protective cover, thereby reducing the surface temperature of the protective cover and preventing the flying debris splashed out during the stamping from thermally adhering to the protective cover.

[0030] 4. A forging equipment for automotive parts blanks, wherein the rotating sleeve drives the protective cover to rotate in the opposite direction through a transmission component, thereby causing the scraper and cleaning plate to scrape off the flying debris splashed inside the protective cover during the stamping process and the water droplets attached to the protective cover. The falling flying debris enters the water tank through the end hole. By cleaning the protective cover, the visibility of the protective cover is increased, making it easier to observe the processing of the raw material blank. By collecting the flying debris in the water tank in a timely manner, the residual heat of the flying debris is absorbed and reused. Attached Figure Description

Detailed Implementation

[0039] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0040] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0041] like Figures 1-7 As shown, a forging device for automotive part blanks provided by the present invention includes a worktable 1, a forging press 3 fixedly connected to the worktable 1 via a support frame 2, a positioning groove 21 fixedly provided on the worktable 1, the positioning groove 21 facing the forging press 3, and further includes:

[0042] A protective cover 4 is rotatably connected to the workbench 1 and is fitted over the positioning groove 21. Preferably, the protective cover 4 is a transparent glass cover. A shell 5 is provided on one side of the protective cover 4. A rotating sleeve 6 is rotatably connected to the shell 5. A connecting plate 10 is fixedly connected to the telescopic end of the forging press 3. An elastic telescopic rod 11 is fixedly connected to the connecting plate 10. A guide groove 12 is spirally provided on the inner wall of the rotating sleeve 6. A sliding member 13 is connected to the elastic telescopic rod 11. The sliding member 13 can move along the guide groove 12. The sliding member 13 is a ball. A transmission assembly 7 for driving the protective cover 4 to rotate is provided between the rotating sleeve 6 and the protective cover 4.

[0043] The protective cover 4 is provided with a spray pipe 14, and a scraper 15 is fixedly connected to the outer wall of the spray pipe 14. The nozzle of the spray pipe 14 faces the inner wall of the protective cover 4, and the scraper 15 abuts against the inner wall of the protective cover 4. The workbench 1 is fixedly connected to a water tank 16. One end of the elastic telescopic rod 11 passes through the inside of the water tank 16. The water tank 16 is provided with a pressure mechanism 8. When the elastic telescopic rod 11 moves downward, the pressure mechanism 8 can force water into the spray pipe 14. The workbench 1 inside the protective cover 4 is provided with multiple end holes 9 that communicate with the water tank 16.

[0044] A cleaning plate 22 is fitted into the inner wall of the protective cover 4. The cleaning plate 22 is rotatably connected to the inner wall of the protective cover 4 by an elastic torsion spring, and the cleaning plate 22 is in contact with the end face of the workbench 1.

[0045] A forging process for automotive part blanks, applied to the forging equipment in the above embodiments, includes the following steps:

[0046] Step S1: Place the cut raw material into the heating furnace and heat it;

[0047] Step S2: The heated raw material blank is conveyed to the positioning groove 21 through the conveying device, and the forging press 3 is started. The forging press 3 performs reciprocating stamping forging on the raw material blank.

[0048] During the forging process of the forging press 3 on the raw material, when the forging press 3 punch head moves downward, the connecting plate 10 drives the elastic telescopic rod 11 to move downward synchronously. The elastic telescopic rod 11 can elastically contract to reduce the instantaneous impact force of the forging press 3 on the raw material and avoid the splashing of raw material slag.

[0049] The sliding member 13 on the elastic telescopic rod 11 moves along the guide groove 12. Under the push of the sliding member 13, the rotating sleeve 6 rotates. The rotating sleeve 6 drives the protective cover 4 to rotate through the transmission assembly 7. At this time, the cleaning plate 22 cleans the flying debris on the workbench 1 into the water tank 16 through the end hole 9. At the same time, the scraper 15 scrapes off the flying debris stuck to the inner wall of the protective cover 4. When the cleaning plate 22 touches the scraper 15, under the push of the scraper 15, the cleaning plate 22 retracts into the inner wall of the protective cover 4.

[0050] The elastic telescopic rod 11 pushes the pressure mechanism 8, which pressurizes water into the nozzle 14. The nozzle 14 further washes the inner wall of the protective cover 4 with high-pressure water. On the one hand, the washing of the nozzle 14 further removes the flying debris left on the protective cover 4 from the previous stamping. On the other hand, the washing of the nozzle 14 reduces the surface temperature of the protective cover 4, preventing the flying debris splashed out during this stamping from thermally sticking to the protective cover 4.

[0051] When the forging press 3's punch head is reset, the rotating sleeve 6 drives the protective cover 4 to rotate in the opposite direction through the transmission component 7, so that the scraper 15 and the cleaning plate 22 scrape off the flying debris splashed inside the protective cover 4 during this punching and the water droplets attached to the protective cover 4. The falling flying debris enters the water tank 16 through the end hole 9. By cleaning the protective cover 4, it is convenient to observe the processing of the raw material. By collecting the flying debris in the water tank 16 in time, the residual heat of the flying debris can also be absorbed and reused.

[0052] Step S3: Remove the forged blank material from the positioning groove 21.

[0053] like Figure 3 and Figure 5As shown, this is a forging equipment for automotive parts blanks provided by the present invention. The pressure mechanism 8 includes an outer sleeve 81, a piston 82, a water pipe 83, a first one-way valve 84, and a second one-way valve 85. The outer sleeve 81 is fixedly connected to the inner end face of the water tank 16. The piston 82 is fixedly connected to one end of the elastic telescopic rod 11, and the piston 82 is slidably sealed to the inner end face of the outer sleeve 81. The water pipe 83 connects the outer sleeve 81 and the nozzle 14. The water pipe 83 is provided with a first one-way valve 84 that unidirectionally flows to the outer sleeve 81, and the outer sleeve 81 is provided with a second one-way valve 85 that unidirectionally flows to the water tank 16.

[0054] In the pressure mechanism 8, when the forging press 3's punch head moves the elastic telescopic rod 11 downward, the elastic telescopic rod 11 drives the piston 82 to slide downward in the outer sleeve 81. The piston 82 presses down on the water flow in the outer sleeve 81. At this time, under the action of the downward pressure, the water flow in the outer sleeve 81 enters the spray pipe 14 through the first one-way valve 84 on the water pipe 83, thereby timely washing away the flying debris adhering to the protective cover 4, preventing the flying debris from accumulating on the protective cover 4 and affecting the detection of the raw material processing process. When the forging press 3's punch head moves the elastic telescopic rod 11 upward, the elastic telescopic rod 11 drives the piston 82 to slide upward in the outer sleeve 81. Under the action of air pressure, the water flow in the water tank 16 enters the outer sleeve 81 through the second one-way valve 85. The second one-way valve 85 is equipped with a filter screen to filter impurities in the water tank 16.

[0055] like Figure 1 As shown, this is a forging equipment for automotive parts blanks provided by the present invention. The transmission assembly 7 includes a transmission wheel 71 and a gear ring 72. The transmission wheel 71 is fixedly connected to the rotating sleeve 6. The gear ring 72 is fixedly connected to the outer wall of the protective cover 4, and the transmission wheel 71 meshes with the gear ring 72. When the rotating sleeve 6 rotates, the rotating sleeve 6 drives the protective cover 4 to rotate through the meshing of the transmission wheel 71 and the gear ring 72.

[0056] like Figure 2 As shown, this is a forging equipment for automotive parts blanks provided by the present invention. The scraper 15 is composed of two straight plates with an included angle of less than 90 degrees. Both straight plates are in contact with the inner wall of the protective cover 4. Several through holes 17 are provided on both sides of one of the straight plates. The through holes 17 on the two sides of the straight plate are interconnected, and the through holes 17 on the two sides of the straight plate face the inner wall of the protective cover 4.

[0057] The scraper 15 removes the debris adhering to the inner wall of the protective cover 4, and the scraper 15 also prevents the water sprayed from the nozzle 14 from splashing everywhere; Figure 2During the process, when the punch head of the forging press 3 moves down, the protective cover 4 rotates counterclockwise. At this time, the scraper 15 scrapes off the flying debris adhering to the inner wall of the protective cover 4, and at the same time, the water flow in the nozzle 14 further washes the inner wall of the protective cover 4. The water flow in the nozzle 14 can also cool the inner wall of the protective cover 4. During this process, the scraper 15 blocks the water flow sprayed from the nozzle 14 to prevent the water flow sprayed from the nozzle 14 from splashing everywhere. Some of the water flow is dispersed into the protective cover 4 through the through holes 17 on the two sides of the straight plate, thereby forming water mist in the protective cover 4 and adsorbing the waste gas generated by the raw material.

[0058] When the forging press 3 press head moves up, the protective cover 4 rotates clockwise. At this time, the scraper 15 can scrape off the flying debris and water droplets attached to the protective cover 4, increasing the cleanliness and visibility of the protective cover 4.

[0059] like Figure 4 As shown, this is a forging equipment for automotive parts blanks provided by the present invention. The rotating sleeve 6 has a plurality of turbine fans 18 fixedly connected to one end inside the outer shell 5, and the outer shell 5 is connected to the worktable 1 by an air pipe 19. The other end of the air pipe 19 is connected to the inside of the protective cover 4. An isolation mesh plate is provided at one end of the air pipe 19 inside the protective cover 4 to prevent large waste residue from falling in. An activated carbon adsorption plate is provided in the outer shell 5.

[0060] When the forging press 3 press head moves up, the rotating sleeve 6 drives the turbine fan 18 to rotate and introduces the exhaust gas in the protective cover 4 into the outer shell 5 through the air pipe 19. The exhaust gas is filtered and purified by the activated carbon adsorption plate.

[0061] A spring 20 is connected between the rotating sleeve 6 and the outer shell 5. When the rotating sleeve 6 rotates, the spring 20 limits the rotation of the rotating sleeve 6, thereby further reducing the instantaneous impact force of the forging press 3 on the raw material.

[0062] A forging process for automotive part blanks, applied to the forging equipment in the above embodiments, includes the following steps:

[0063] Step S1: Place the cut raw material into the heating furnace and heat it;

[0064] Step S2: The heated raw material blank is conveyed to the positioning groove 21 through the conveying device, and the forging press 3 is started. The forging press 3 performs reciprocating stamping forging on the raw material blank.

[0065] During the forging process of the forging press 3 for the blank raw material, when the forging press 3 punch head moves downward, the connecting plate 10 drives the elastic telescopic rod 11 to move downward synchronously.

[0066] The sliding member 13 on the elastic telescopic rod 11 moves along the guide groove 12. Under the push of the sliding member 13, the rotating sleeve 6 rotates. The rotating sleeve 6 drives the protective cover 4 to rotate through the transmission assembly 7. At this time, the cleaning plate 22 cleans the flying debris on the workbench 1 into the water tank 16 through the end hole 9. At the same time, the scraper 15 scrapes off the flying debris stuck to the inner wall of the protective cover 4. When the cleaning plate 22 touches the scraper 15, under the push of the scraper 15, the cleaning plate 22 retracts into the inner wall of the protective cover 4.

[0067] The elastic telescopic rod 11 pushes the pressure mechanism 8, which pressurizes water into the nozzle 14. The nozzle 14 then uses high-pressure water to further flush the inner wall of the protective cover 4.

[0068] When the forging press 3's punch head is reset, the rotating sleeve 6 drives the protective cover 4 to rotate in the opposite direction through the transmission assembly 7, thereby causing the scraper 15 and the cleaning plate 22 to scrape away the flying debris splashed inside the protective cover 4 during this punching and the water droplets attached to the protective cover 4. The falling flying debris enters the water tank 16 through the end hole 9; at the same time, the rotating sleeve 6 drives the turbine fan 18 to rotate and introduces the exhaust gas in the protective cover 4 into the outer shell 5 through the air pipe 19. The exhaust gas is filtered and purified by the activated carbon adsorption plate.

[0069] Step S3: Remove the forged blank material from the positioning groove 21.

[0070] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0071] During step S2 above, when the forging press 3's punch head moves downwards, before the forging press 3 contacts the raw material:

[0072] The elastic telescopic rod 11 can elastically contract, reducing the instantaneous impact force of the forging press 3 on the raw material blank and preventing the raw material blank slag from splashing. At the same time, under the action of water pressure in the pressure mechanism 8, the buffering effect on the forging press 3 is further increased; thus, the splashing of raw material blank slag is prevented before the forging press 3 contacts the raw material blank.

[0073] At this time, the protective cover 4 rotates, and the cleaning plate 22 cleans the flying debris on the workbench 1 into the water tank 16 through the end hole 9. At the same time, the scraper 15 scrapes off the flying debris stuck to the inner wall of the protective cover 4.

[0074] Furthermore, in the pressure mechanism 8, the water flow in the nozzle 14 washes the inner wall of the protective cover 4, cleaning the surface of the protective cover 4 while cooling the inner wall of the protective cover 4. By reducing the surface temperature of the protective cover 4, the flying debris splashed out during the stamping process is prevented from thermally adhering to the protective cover 4. During this process, the scraper 15 blocks the water flow sprayed from the nozzle 14 to prevent the water flow sprayed from the nozzle 14 from splashing everywhere. Some of the water flow is dispersed into the protective cover 4 through the through holes 17 on the two sides of the straight plate, thereby forming a water mist in the protective cover 4, which adsorbs the waste gas generated by the raw material.

[0075] When the forging press 3 returns to its original position after stamping the blank material:

[0076] The rotating sleeve 6 drives the protective cover 4 to rotate in the opposite direction through the transmission component 7, so that the scraper 15 and the cleaning plate 22 scrape off the flying debris splashed inside the protective cover 4 and the water droplets attached to the protective cover 4 during the stamping. The falling flying debris enters the water tank 16 through the end hole 9. By cleaning the protective cover 4, the visibility of the protective cover 4 is increased, making it easier to observe the processing of the raw material. By collecting the flying debris in the water tank 16 in a timely manner, the residual heat of the flying debris is further absorbed and reused.

[0077] The rotating sleeve 6 simultaneously drives the turbine fan 18 to rotate and introduces the exhaust gas in the protective cover 4 into the outer shell 5 through the air pipe 19. The exhaust gas is then filtered and purified by the activated carbon adsorption plate.

[0078] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

The gear ring (72) is fixedly connected to the outer wall of the protective cover (4), and the transmission wheel (71) meshes with the gear ring (72).

4. The forging equipment for automotive part blanks according to claim 1, characterized in that, A spring (20) is connected between the rotating sleeve (6) and the outer shell (5).

5. The forging equipment for automotive part blanks according to claim 1, characterized in that, The sliding element (13) is a ball bearing.

6. A forging process for automotive part blanks, applied to the forging equipment for automotive part blanks according to any one of claims 1-5, characterized in that, Includes the following steps: Step S1: Place the cut raw material into the heating furnace and heat it; Step S2: The heated raw material is conveyed to the positioning slot (21) through the conveying device, and the forging press (3) is started. The forging press (3) performs reciprocating stamping forging on the raw material. During the forging process of the forging press (3) on the blank raw material, when the forging press (3) punch head moves downward, the connecting plate (10) drives the elastic telescopic rod (11) to move downward synchronously; The sliding part (13) on the elastic telescopic rod (11) moves along the guide groove (12). Under the push of the sliding part (13), the rotating sleeve (6) rotates. The rotating sleeve (6) drives the protective cover (4) to rotate through the transmission assembly (7). At this time, the cleaning plate (22) cleans the flying debris on the workbench (1) into the water tank (16) through the end hole (9). At the same time, the scraper (15) scrapes off the flying debris stuck to the inner wall of the protective cover (4). When the cleaning plate (22) touches the scraper (15), under the push of the scraper (15), the cleaning plate (22) retracts into the inner wall of the protective cover (4). The elastic telescopic rod (11) pushes the pressure mechanism (8), which presses water into the nozzle (14), and the nozzle (14) further flushes the inner wall of the protective cover (4) with high-pressure water. When the forging press (3) resets its punching head, the rotating sleeve (6) drives the protective cover (4) to rotate in the opposite direction through the transmission assembly (7), so that the scraper (15) and the cleaning plate (22) scrape off the flying debris splashed inside the protective cover (4) and the water droplets attached to the protective cover (4) during this punching. Step S3: Remove the forged blank material from the positioning groove (21).
