Description

Technical Field

[0001] This invention relates to the field of gear forging equipment technology, and specifically to a forging equipment for gear production. Background Technology

[0002] The manufacturing process of gears mainly includes two methods: casting and forging. Among them, forged gears are gradually replacing cast gears in the market and becoming the mainstream choice due to their significant advantages such as dense internal structure, excellent strength, long service life and reliable explosion-proof performance.

[0003] In existing gear forging technology, workers typically place a red-hot metal billet into a forging die. The forging hammer of the forging machine then strikes the top of the billet repeatedly. As the hammering continues, the height of the billet gradually decreases while its diameter increases, until the height of the billet perfectly matches the height of the forging die, and the sides of the billet are in close contact with the die surface, creating pressure and shaping the desired structure on the side surface of the billet. However, since the initial height of the billet far exceeds the depth of the forging die, workers often need to use clamps to hold and fix the billet during actual operation. This clamping forging method not only significantly reduces production efficiency but also poses a potential threat to worker safety. Therefore, we propose a forging equipment for gear production. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention provides a forging equipment for gear production, which overcomes the shortcomings of the prior art, has a reasonable design and compact structure, and solves the problem that workers use clamps to hold metal billets during existing forging processes, which affects production efficiency and poses potential threats.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] See attached document Figure 1-8 A forging equipment for gear production includes a machine body 1. A hydraulic cylinder is provided on the machine body 1. The output of the hydraulic cylinder is connected to a forging hammer 2. By activating the hydraulic cylinder, the forging hammer 2 can be controlled to perform vertical lifting and lowering movements. A forging die 3 is provided on the worktable of the machine body 1. The forging hammer 2 is located directly above the forging die 3. The forging die 3 is provided with a die cavity 31 for placing metal billets. The forging hammer 2 can continuously hammer the metal billets placed in the die cavity 31 downwards to shape them.

[0033] Both sides of the forging die 3 are equipped with support mechanisms to support the metal billet during the forging process and prevent it from flying out of the die cavity 31 when the forging hammer 2 strikes the metal billet, thus affecting subsequent forging.

[0034] The support mechanism includes an adjustment plate 41 installed on the machine body 1. The adjustment plate 41 has a pair of parallel vertical plates 42. Both vertical plates 42 have parallel inclined grooves 43. A slider 44 is provided between the two vertical plates 42. Both ends of the slider 44 are inserted into the inclined grooves 43 and can slide along the inclined grooves 43. Multiple sliding rods 45 are slidably connected inside the slider 44. A clamping plate 46 is provided on the side of the sliding rod 45 facing the forging die 3. The clamping plate 46 has a V-shaped clamping groove on the side of the clamping plate 46 facing the forging die 3 for abutting against the outer wall of the upper part of the metal billet. A spring 47 is provided between the clamping plate 46 and the slider 44 to buffer and provide clamping force.

[0035] When the forging hammer 2 continuously hammers the metal billet placed in the mold cavity 31, the clamping plate 46, supported by the spring 47, can support the metal billet and prevent it from tipping over or popping out of the mold cavity 31. Under the continuous hammering of the forging hammer 2, the metal billet will gradually thicken. Since the slide bar 45 can slide inside the slider 44, the spring 47 will compress and deform to automatically adjust the position of the clamping plate 46 when the metal billet thickens, always maintaining effective support for the metal billet. During this process, the slider 44 is controlled to move away from the mold cavity 31 in the inclined groove 43. At this time, the clamping plate 46 will also move away from the metal billet, giving the metal billet space to thicken. The metal billet will not be deformed due to excessive clamping force, which will affect the forging quality. No manual support is required, which greatly improves efficiency and operational safety.

[0036] The inclined groove 43 is arranged downwards on the side away from the forging die 3. When the slider 44 moves away from the forging die 3, it will move along the inclined trajectory of the inclined groove 43 and drive the clamping plate 46 to move downwards in sync. During this process, the clamping plates 46 on both sides will gradually move towards the lower part of the metal billet and clamp it. As the forging hammer 2 strikes, the height of the metal billet gradually decreases, and the clamping plates 46 will gradually move towards the lower part of the metal billet and clamp it, thereby avoiding interference with the continuous hammering operation of the forging hammer 2 and greatly improving the forging efficiency. When the height of the metal billet decreases to a suitable height, most of the metal billet enters the die cavity 31. At this time, the clamping plates 46 on both sides will move out from under the forging hammer 2 and no longer clamp the metal billet. Since the height between the forging hammer 2 and the metal billet will not be too high during each hammering, the metal billet will not jump out of the die cavity 31 when the forging hammer 2 strikes it, and the clamping plates 46 are no longer needed for support.

[0037] The machine body 1 is equipped with a drive mechanism for driving the support mechanisms on both sides to move synchronously. The drive mechanism includes a first cylinder 51 installed on the back of the machine body 1. The output end of the first cylinder 51 is connected to a drive frame 52. The drive frame 52 is equipped with a pair of drive frames 53. The ends of the sliders 44 on both sides are respectively inserted into the inner cavity of one of the drive frames 53. The inner cavity of the drive frame 53 is a long strip structure. When the first cylinder 51 works, its output end will drive the drive frame 52 to move up and down. At this time, the drive frame 53 can push the sliders 44 to move up and down, further causing the sliders 44 to move along the inclined groove 43, thereby realizing the support or release action of the metal billet. The drive frame 52 is equipped with a pair of guide rods 54 that penetrate the worktable of the machine body 1, which can prevent the drive frame 52 from shaking or deviating during the movement, ensuring the accuracy of the support mechanism movement, and thus improving the forging quality.

[0038] The adjusting plate 41 has several elongated slots 48 on both sides. The machine body 1 has several screws 11 that match the elongated slots 48 and are inserted into them. Nuts are screwed into the outer wall of the screws 11 to position the adjusting plate 41. When installing or adjusting the position of the support mechanism, the nuts can be loosened according to actual needs to allow the adjusting plate 41 to move horizontally, thereby facilitating the adjustment of the position of the support mechanism relative to the forging die 3 to adapt to the forging requirements of metal billets of different sizes and shapes, and improving the versatility and flexibility of the equipment.

[0039] The machine body 1 is equipped with an ejection mechanism below the worktable, which is used to eject the forged metal billet from the cavity 31 of the forging die 3 without manual operation. The ejection mechanism includes a mounting frame 61 installed below the worktable of the machine body 1. The mounting frame 61 is equipped with a second cylinder 62. The top of the output shaft of the second cylinder 62 is equipped with an ejection block 63 that is inserted into the bottom of the cavity 31. The ejection block 63 is adapted to the shape of the inner cavity of the cavity 31 to ensure the shape of the bottom of the forged metal billet and to smoothly eject the forged metal billet from the cavity 31. When forging is completed, the second cylinder 62 is activated, and the output shaft of the second cylinder 62 moves upward, driving the ejection block 63 to push the metal billet out of the cavity 31. This can realize automated demolding, reduce manual operation, and quickly and effectively remove the forged metal billet from the cavity 31, thereby improving production efficiency.

[0040] The ejector block 63 is threadedly connected to the output shaft of the second cylinder 62. When the ejector block 63 needs to be replaced, the second cylinder 62 is started, causing the ejector block 63 to move upward out of the mold cavity 31. At this time, the ejector block 63 can be installed and removed, which is convenient for adjustment according to different models of forging dies 3.

[0041] The diameter of the output shaft of the second cylinder 62 is smaller than the width of the ejector block 63. The mounting bracket 61 is provided with a limiting plate 64 that abuts against the bottom of the ejector block 63. When the ejector block 63 is subjected to pressure at the bottom of the metal billet, the limiting plate 64 will abut against the bottom of the ejector block 63 to prevent it from shaking randomly and affecting the forging quality.

[0042] The bottom of the forging die 3 is provided with a limiting block 32. A groove is provided on the worktable of the machine body 1 for the insertion of the limiting block 32 for positioning and installation of the forging die 3, ensuring that the position of the forging die 3 on the worktable is accurate. Several positioning holes 33 are provided on both sides of the forging die 3. Several mounting holes that match the positioning holes 33 are provided on the worktable of the machine body 1. The forging die 3 can be fixed to the worktable by the cooperation of bolts and nuts and other connecting parts, so as to prevent the forging die 3 from moving or shaking during the forging process, thereby improving the forging quality and the product qualification rate. It is also more convenient and quick to change different models of forging dies 3.

[0043] The machine body 1 is equipped with a feeding mechanism for pushing the formed billet out of the machine body 1. The feeding mechanism includes a pair of fixed plates 71 installed on the machine body 1. A bearing plate 72 is rotatably connected between the two fixed plates 71. One end of the bearing plate 72 overlaps the forging die 3, and the other end extends out of the machine body 1. The bearing plate 72 has a slot 73 that matches the mold cavity 31. When it is necessary to feed the cast metal billet out, the metal billet is first ejected to the upper surface of the forging die 3 by the ejection mechanism. Then, the bearing plate 72 is controlled to rotate. At this time, the bearing plate 72 will push the metal billet to slide down along the top of the bearing plate 72 under its own gravity, thereby realizing the effect of automated feeding, reducing manual operation and greatly improving production efficiency.

[0044] The top front side and left and right sides of the bearing plate 72 are provided with upwardly extending edges 74. The edges 74 can effectively collect the residue falling from the metal billet during the forging process, preventing the residue from being scattered in the working environment and affecting the subsequent processing accuracy and the cleanliness of the working environment.

[0045] The top left and right sides of the forging die 3 are provided with outer edges 34 that fit the outer wall of the bearing plate 72, which are used to position the bearing plate 72, ensure accurate positioning of the bearing plate 72, and ensure the smooth progress of the material feeding process.

[0046] A pair of pressure rods 55 are provided on the drive frame 52. The two pressure rods 55 are located above the rear end of the support plate 72. When the pressure rods 55 move downward, they push the support plate 72 to deflect. When the forging is completed and the blank needs to be unloaded, the first cylinder 51 drives the drive frame 52 to move downward again. The pressure rods 55 on the drive frame 52 will move downward and push the rear end of the support plate 72, causing the support plate 72 to deflect. This realizes the automatic unloading of metal blanks without the need for an additional dedicated unloading drive device, which simplifies the equipment structure and reduces the cost of the equipment.

[0047] When the pressure bar 55 is no longer pressing the bearing plate 72, the bearing plate 72 will reset under its own gravity. In order to further ensure that the bearing plate 72 can reset, a torsion spring can be provided between the bearing plate 72 and the fixed plate 71.

[0048] Working principle: During forging, the red-hot metal billet is placed into the cavity 31 of the forging die 3. The hydraulic cylinder is activated to control the forging hammer 2 to continuously hammer the metal billet. At the same time, the first cylinder 51 is controlled to work, and its output end drives the drive frame 52 to move downward. This further causes the drive frame 53 to push the slider 44 to move away from the forging die 3 along the inclined groove 43. The slider 44 drives the slide rod 45 and the clamping plate 46 to gradually move away from the metal billet. During this process, the clamping plate 46 will continuously abut against the outer wall of the metal billet under the action of the spring 47, supporting the billet and preventing it from tilting or popping out of the die cavity 31. Under continuous hammering, the metal billet will gradually become thicker and shorter. As the clamping plate 46 gradually moves away from the metal billet, it will tilt downward. While providing space for the metal billet to thicken, it can ensure the clamping of the metal billet. By clamping the metal billet by gradually moving downward when the metal billet becomes shorter, it is ensured that the clamping plate 46 will not affect the continuous hammering of the metal billet by the forging hammer 2.

[0049] After forging is completed, the second cylinder 62 is started, and its output shaft drives the ejector block 63 to eject the forged metal billet from the mold cavity 31. Then, the first cylinder 51 is started, and the drive frame 52 drives the pressure rod 55 to move downward. At this time, the pressure rod 55 will push the bearing plate 72 to deflect. The metal billet and impurities generated during forging will slide towards each other along the top of the bearing plate 72 under their own gravity, realizing the effect of automated material feeding and automated cleaning.
