Description

Technical Field

[0001] The invention belongs to the technical field of module structures, and in particular relates to a gear production module. Background Art

[0002] Gears are an indispensable component in the field of machinery; they can not only transmit power efficiently, but also flexibly control the speed and direction of rotation. Their wide range of applications has penetrated every corner from precision instruments to heavy machinery. With the evolution of technology, the gear manufacturing process has undergone countless innovations and improvements. Today, the production technology of gears has developed to a very mature level, covering various methods from traditional manual to high-precision CNC machine tools. Among them, CNC machine tool processing firmly sits at the top of production accuracy. However, this process of pursuing extreme precision is often accompanied by the sacrifice of production efficiency. In order to solve the problem of low production efficiency, gear manufacturers combine die forging and machine tool processing, which not only ensures that each gear can meet the high-precision standards required for use, but also improves the production efficiency of gears, truly achieving a win-win situation of quality and efficiency.

[0003] However, there are the following problems when producing gear blanks through die forging:

[0004] Oxide slag or metal chips will be produced and dropped during the forging process of the metal blank. If the oxide scale is pressed into the surface of the forging during the forging process, it will cause defects such as depressions and spots on the surface, affecting the appearance quality and dimensional accuracy of the forging, and may require additional finishing or become a defective product; and the oxide scale is hard and brittle, which can easily aggravate the wear of the die cavity during the die forging process and shorten the service life of the die.

[0005] In the die forging process, in addition to effectively controlling and reducing the generation of oxide slag and its impact on the quality of the finished product, the demoulding problem of the gear cannot be ignored. The dense tooth structure in the gear design invisibly increases the contact area between the mold and the molded part, thereby significantly increasing the friction resistance between the two. This causes the gear to be poorly demoulded during the demoulding process, affecting the smoothness and efficiency of the entire production process.

[0006] Due to the difficulty in demolding the gears, the gear forming process, which originally required multiple processes and multiple modules to work together, was seriously slowed down, causing manufacturers to turn to a single module to complete all forming steps, and only one process is required to forge the finished gears. However, this change has led to a significant increase in the error cost of gear production. Once a mistake occurs in the forging process, the impact will directly affect the entire batch of products, and the loss caused will be more serious than step-by-step processing. In addition, the configuration and adjustment flexibility of the production line is greatly reduced, which limits the ability of manufacturers to quickly respond to market changes and flexibly switch to produce gear products of different models or designs.

[0007] In summary, it is found that the prior art has at least the following technical problems:

[0008] The existing gear production modules have the problem of being difficult to efficiently control and remove slag and metal chips during the forging process, as well as the problem of reduced production efficiency due to difficulty in demolding, increased production error costs during single module forging, and reduced flexibility of the production line.

[0031] In addition, in this specific embodiment, if the connection or fixing method between components is not specifically described, the connection or fixing method can be through bolt fixing or pin fixing, or pin shaft connection and the like commonly used in the prior art, and therefore, it will not be described in detail in this embodiment.

[0032] Embodiment 1

[0033] See also Figure 1 , 2A gear production die set includes a die base 1, wherein the die base 1 includes a lower die base 111 and an upper die base 12, wherein the lower die base 111 is provided with a first mounting groove 111 in its width direction; wherein the upper die base 1 is provided with a second mounting groove 121 in its width direction, wherein a convex film 6 is provided on the second mounting groove 121, wherein the design of the first mounting groove 111 and the second mounting groove 121 not only provides a solid foundation for the installation and adjustment of the die set, but also facilitates the rapid replacement and maintenance of the die set, thereby enhancing the flexibility and adaptability of the production system. The convex film 6 and the concave die 2 are combined into a gear forging die set, wherein the gear forging die set includes a rough forging die set 13, a fine forging die set 14, and a precision forging die set 15; the modular design in stages can make the wear distribution of the die more uniform, extend the service life of the die, and reduce product quality problems caused by die wear. A guide rod 61 and a first spring 62 are provided between the lower die base 111 and the upper die base 1. The guide rod 61 is provided at the end angles of the lower die base 111 and the upper die base 1. The upper die base 1 is slidably provided on the guide rod 61, and the first spring 62 is sleeved on the guide rod 61. The guide rod 61 serves as a sliding track for the upper die base 1 to ensure the linear motion of the upper die base 1 during the opening and closing process, to avoid deviation or shaking, and thus to improve the accuracy and stability of the mold closure. The first spring 62 is sleeved on the guide rod 61 to play a role of buffering and resetting. When the upper die base 1 slides on the guide rod 61, the spring can absorb the impact force, reduce the direct hard collision between the dies, protect the dies from damage, and extend the service life. At the same time, after the mold opening operation is completed, the restoring force of the spring can help the upper die base 1 return to its original position quickly and accurately, to prepare for the next round of forging, and to improve production efficiency and continuity.

[0034] See also Figure 3, a die 2, wherein the die 2 comprises a first die 212 and a second die 222, wherein the first die 212 and the second die 222 respectively have a first half cavity 211 and a second half cavity 221; the first die 212 and the second die 222 are slidably mounted on the first mounting groove 111, and the first die 212 and the second die 222 can be combined and separated; when the first die 212 and the second die 222 are combined, the first half cavity 211 and the second half cavity 221 form a complete gear processing cavity 23; a die opening and closing mechanism 4, wherein the die opening and closing mechanism 4 is used to control the combination and separation of the first die 212 and the second die 222; through the combination and separation of the first die 212 and the second die 222, the die set can realize efficient forming of the gear rough blank during the forging process; it not only simplifies the die maintenance, but also facilitates the cleaning of the die cavity before and after forging, effectively solving the problem that the oxide slag and metal chips are difficult to remove. Furthermore, when the first die 212 and the second die 222 are separated, a larger opening is formed, making it easier to take the forged gear blank out of the die and put it in, reducing the blocking time caused by demolding difficulties and improving the transfer efficiency from one module to the next.

[0035] See also Figure 7 The first die 212 and the second die 222 are both composed of a die body 24 and a slide bar 25; a second slide groove 26 is provided at the bottom of the die body 24, and the second slide groove 26 is parallel to the first mounting groove 111; the slide bar 25 is located in the first mounting groove 111, a part of the slide bar 25 is connected to the first die 212 or the second die 222, and the top of the other part of the slide bar 25 is flat; the flat part of the slide bar 25 is in the second slide groove 26. Through the combination of the die body 24 and the slide bar 25, under the cooperation of the second slide groove 26 and the slide bar 25, not only the structural stability of the die is enhanced, but also the assembly and adjustment of the die become simple and quick. The most important thing is that the setting of the slide bar 25 can effectively prevent the oxide slag and metal chips generated during the forging process from falling into the first mounting groove 111 when the first die 212 and the second die 222 are separated. It not only avoids contamination and potential damage to the mold mounting groove by impurities, but also simplifies the cleaning process; reducing the intrusion of oxide slag and metal chips on key mold components means less need for maintenance and repair, thereby reducing maintenance costs and extending the service life of production molds.

[0036] See also Figure 5The mold opening and closing mechanism 4 includes a transmission rod 41, a transmission block 42 and a control block 43, and the control block 43 is controlled to rise and fall by a telescopic cylinder; one end of the transmission rod 41 is connected to the first die 212 or the second die 222, and the other end of the transmission rod 41 is connected to the transmission block 42; the contact surfaces of the transmission block 42 and the control block 43 are inclined surfaces and fit each other, and the position of the transmission block 42 is controlled by adjusting the height of the control block 43, thereby controlling the relative position of the first die 212 and the second die 222. The mold opening and closing mechanism 4 realizes precise control of the opening and closing of the mold through the inclined surface matching design of the transmission rod 41, the transmission block 42 and the control block 43, which not only improves the smoothness of demoulding, but also reduces product quality problems caused by mold wear, and greatly improves production efficiency. The control block 43 is controlled by the telescopic cylinder to rise and fall, so as to realize precise control of the merging and separation of the first die 212 and the second die 222. Among them, the inclined plane principle is used to allow the transmission blocks 42 to move away from or closer to each other under the drive of the control block 43, thereby driving the opening and closing of the die 2, demonstrating a high degree of mechanical coordination and precision.

[0037] See also Figure 3 The die opening and closing mechanism 4 further includes a push rod 46, which is located in the gear processing cavity 23 and is used to push the gear out of the die 2 so as to transfer it to the subsequent forging process; a first connecting hole 461 is provided on the lower die seat 111, and the tops of the push rod 46 and the first connecting hole 461 are both conical. A second connecting hole 462 is provided on the control block 43, and a first limiting protrusion 463 is provided in the second connecting hole 462; the push rod 46 is located in the first connecting hole 461, and the push rod 46 passes through the second connecting hole 462, and a first limiting plate 464 is provided at the end of the push rod 46, a second limiting plate 465 is provided between the lower die seat 111 and the control block 43, and a second limiting protrusion 466 is provided on the push rod 46. While the control block 43 realizes the opening and closing of the mold by cooperating with the inclined surface of the transmission block 42, the control block 43 can also drive the ejector 46 to rise, realizing the automatic demoulding function. This means that after the gear forging is completed, the ejector 46 can automatically or under control eject the gear blank from the die 2, reducing manual intervention and improving production efficiency.

[0038] See also Figure 4The mold opening and closing mechanism 4 also includes a mounting plate 44 and a reset spring 45; the mounting plate 44 is arranged on the lower mold base 111, and the mounting plate 44 is located on the other side of the inclined surface of the transmission block 42; the reset spring 45 is located between the mounting plate 44 and the transmission block 42, and the reset spring 45 is used to reset the transmission block 42 after the position is adjusted. The mounting plate 44 and the reset spring 45 can prompt the transmission block 42 to return to the initial position quickly and accurately, so as to prepare for the next round of mold opening and closing actions. The mold opening and closing mechanism 4 also includes a pull rod 47, and the pull rod 47 is used for the control block 43 to drive the transmission block 42 to move; a first slide groove 471 is provided on the inclined surface of the transmission block 42, and the first slide groove 471 is located on both sides of the inclined surface end of the control block 43; the control block 43 is provided with a connecting rod 472 on both sides of the inclined surface end; one end of the pull rod 47 is swingably arranged on the connecting rod 472, and the other end of the pull rod 47 is slidably arranged in the first slide groove 471. Not only does the control block 43 achieve precise control of the transmission block 42, allowing the transmission block 42 to move smoothly along a predetermined path, but the swinging and sliding movement of the pull rod 47 also increases the flexibility and response speed of the system during the mold opening and closing process.

[0039] See also Figure 6 , also includes an injection mechanism 5, the injection mechanism 5 includes a vertical rod 51, an adjusting rod 52 and a rocker 53; the vertical rod 51 is arranged on the lower die base 111, the middle part of the rocker 53 is rotatably arranged on the vertical rod 51, one end of the rocker 53 is provided with a nozzle 54, and the other end of the rocker 53 is provided with a control groove 55; one end of the adjusting rod 52 is installed on the first die 212 or the second die 222, and the other end of the adjusting rod 52 is located in the control groove 55; when the first die 212 and the second die 222 are separated, the adjusting rod 52 pushes the rocker 53 to stand up, so that the nozzle 54 can clean the inside of the die 2. Specifically, one end of the adjusting rod 52 is installed on the die 2, and the other end is connected to the rocker 53 through the control groove 55, so that when the die 2 is separated, the adjusting rod 52 can automatically start the rocker 53 to stand up and activate the injection mechanism 5 to perform cleaning work; ensuring the seamless connection between the cleaning process and the production process and improving production continuity.

[0040] The nozzle 54 is connected to the jet system and the liquid spray system; the nozzle 54 sprays air into the die 2 with the help of the jet system to remove the oxide slag or metal chips dropped during the forging process; the jet system can be replaced by an air suction system to remove the oxide slag or metal chips dropped during the forging process by vacuuming. The liquid spray system can spray lubricants or mold release agents, and the nozzle 54 sprays lubricants or mold release agents into the die 2 with the help of the liquid spray system to facilitate demolding after the gear is forged. Specifically, the nozzle 54 is not only connected to the jet system to remove the oxide slag and metal chips generated during the forging process, but can also be switched to the air suction system to more thoroughly clean the mold cavity by vacuuming, reducing the need for manual cleaning, reducing the labor intensity of operators, and at the same time improving the thoroughness of cleaning and reducing potential damage to the mold. The liquid spray system can spray lubricants or mold release agents, which provides a guarantee for the smooth demolding of the gear after forging. Through the precisely controlled liquid spray, the friction between the mold and the gear is reduced, which not only improves the demolding efficiency, but also reduces the wear on the mold and extends the service life of the mold.

[0041] Embodiment 2

[0042] A gear production module in Example 1 is applied, and the specific demoulding process is as follows:

[0043] When the telescopic cylinder controls the control block 43 to rise, the control block 43 contacts the transmission block 42 through the inclined surface, and uses the inclined surface to move the transmission blocks 42 away from each other, so that the first die 212 and the second die 222 are transformed from merging to separation; as the control block 43 rises, the first die 212 and the second die 222 are separated to a greater extent; when the control block 43 just starts to rise, the first limiting protrusion 463 is located above the second limiting protrusion 466, and the push rod 46 rises as the control block 43 rises; when the second limiting plate 465 contacts the lower die base 111, the push rod 46 no longer rises as the control block 43 rises; until the first limiting protrusion 463 is located below the second limiting protrusion 466, the push rod 46 separates from the gear and quickly resets. By pre-moving the ejector pin 46, it is ensured that the loading of the new gear blank can be carried out synchronously before the mold is closed, without waiting for the mold to be fully opened before loading, thus reducing unnecessary production pauses, increasing the output of gears per unit time, and enhancing production efficiency.

[0044] Specifically, the ejector pin 46 descends before the die 2 merges, providing ample time and space for the operator or automated robot to quickly and unhindered place the new gear blank into the mold cavity; this reduces the waiting time between mold closing and new material preparation, improves production rhythm, and makes the entire production line more smooth and continuous.

[0045] Embodiment 3

[0046] A gear production module in the first embodiment is applied, and the specific mold closing process is as follows:

[0047] When the telescopic cylinder controls the control block 43 to descend, the control block 43 allows the transmission blocks 42 to approach each other with the help of the pull rod 47 and the return spring 45, so that the first die 212 and the second die 222 change from separation to merging; as the control block 43 descends, the degree of merging of the first die 212 and the second die 222 becomes greater and greater.

[0048] Specifically, as the control block 43 slowly descends under the action of the telescopic cylinder, the connecting rods 472 installed on both sides of the inclined surface end of the control block 43 start to pull the transmission block 42 through interaction with the pull rod 47. At this time, the return spring 45 plays an important role, which not only helps maintain the stability of the system, but also provides the necessary resilience to ensure that the transmission block 42 can move smoothly and quickly along the preset trajectory.

[0049] Embodiment 4

[0050] A gear production module in the first embodiment is applied. The second embodiment is a demoulding process in which the push rod 46 and the gear blank can be naturally separated after the production module is assembled into the gear blank. The present embodiment is a demoulding process in which the push rod 46 and the gear blank cannot be naturally separated. The specific demoulding process is as follows:

[0051] When the telescopic cylinder controls the control block 43 to rise, the control block 43 contacts the transmission block 42 through the inclined surface, and uses the inclined surface to move the transmission blocks 42 away from each other, so that the first die 212 and the second die 222 are transformed from merging to separation; as the control block 43 rises, the first die 212 and the second die 222 are separated to a greater extent; when the control block 43 just starts to rise, the first limiting protrusion 463 is located above the second limiting protrusion 466, and the push rod 46 rises as the control block 43 rises; when the second limiting plate 465 contacts the lower die base 111, the push rod 46 no longer rises as the control block 43 rises; until the first limiting protrusion 463 is located below the second limiting protrusion 466, the push rod 46 is not separated from the gear; the control block 43 is controlled to descend by the telescopic cylinder, and the push rod 46 is separated from the gear under the action of the first limiting protrusion 463, the second limiting protrusion 466 and the first limiting plate 464.

[0052] In order to solve the problem that the gears fail to separate naturally, the control block 43 is moved downward by controlling the telescopic cylinder. At this time, the first limiting protrusion 463 moves below the second limiting protrusion 466, and the first limiting plate 464 and the second limiting protrusion 466 work together to provide additional thrust for the push rod 46 or adjust the thrust angle of the push rod 46 to overcome the demolding resistance; at the same time, the first limiting plate 464 set at the end of the push rod 46 can also provide additional thrust for the push rod 46 or adjust the thrust angle of the push rod 46 to overcome the demolding resistance.

[0053] The technical effects of the present invention are mainly reflected in the following aspects: the gear production module not only controls the precise opening and closing of the mold through the inclined surface of the control block 43 and the transmission block 42, but also realizes automatic demoulding by linking the ejector rod 46; in addition, one end of the adjustment rod 52 in the injection mechanism 5 is installed on the die 2, and the other end is connected to the rocker 53 through the control groove 55, so that when the die 2 is separated, the adjustment rod 52 can automatically start the rocker 53 to stand up and activate the injection mechanism 5 for cleaning; it ensures the seamless connection between the cleaning process and the production process, and improves the continuity of production. Through the combination and separation of the first die 212 and the second die 222, the module can realize the efficient forming of the gear rough blank during the forging process; it not only simplifies the mold maintenance, but also facilitates the cleaning of the mold cavity before and after forging, effectively solving the problem of difficult removal of oxide slag and metal chips. Furthermore, when the first die 212 and the second die 222 are separated, a larger opening is formed, making it easier to take the forged gear blank out of the die and put it in, reducing the blocking time caused by demolding difficulties and improving the transfer efficiency from one module to the next.

[0054] In addition, as common knowledge in the industry, the jet system, air suction system and liquid spray system mentioned above are common knowledge, so their principles and structures will not be described in detail.

[0055] Of course, the above are only typical examples of the present invention. In addition, the present invention may also have many other specific implementations. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
