Description

Technical Field

[0001] This application relates to the technical field of forging processing equipment, specifically to an upsetting machine for forging. Background Technology

[0002] Upsetting is a key process in forging production. Its purpose is to use external force to increase the cross-sectional area and decrease the height of the billet, thereby changing the shape and size of the billet. This provides a suitable billet shape for subsequent forging processes, such as forging shafts, discs, and other forgings that meet the requirements. It is an important step in achieving precise forming of forgings.

[0003] For example, the patent with publication number CN220591434U discloses an upsetting machine for forging, including a base, an electric push rod, a scraper, and a die holder. The beneficial effect of this utility model is that by activating the electric push rod, one end of the electric push rod pushes the scraper to scrape off metal chips inside the die holder multiple times. The scraped metal chips enter the inside of the collection box through the inclined surface of the discharge port. When the inside of the collection box is full of metal chips, the clamping pin is removed from the limiting groove and then emptied, which facilitates the quick cleaning of the die holder.

[0004] However, the upsetting machine for forging of the forgings mentioned above lacks an effective anti-deviation and stable support structure in the upsetting process of forgings. Due to the lack of a dedicated limiting and fixing device, the forgings are prone to horizontal or vertical deviation when subjected to the pressure of the punch head. This not only easily leads to uneven upsetting of different parts of the forging, resulting in local over-thickness or under-thinness, affecting the dimensional accuracy of the product, but also causes irregular friction between the forging and the punch head and die base due to the shaking of the forging, which aggravates equipment wear and reduces the overall accuracy of the upsetting process.

[0005] Furthermore, the equipment uses a structure where the workpiece passes through a circular hole into the die holder for stamping. After stamping, the cross-sectional area of ​​the forging will increase due to the upsetting effect. At this time, the enlarged forging may not be easy to pull out from the original circular hole, which may cause the forging to get stuck in the die holder. This will not only affect the subsequent processing flow, but may also cause damage to the forging or the equipment due to forced extraction. Therefore, it is necessary to provide an upsetting machine for forging to solve the above problems. Utility Model Content

[0006] Based on the aforementioned problems in the prior art, the problem to be solved in this application is to provide an upsetting machine for forging, which solves the problems of easy deviation and unstable support during forging upsetting, resulting in low processing accuracy, poor product quality, and rapid equipment wear, as well as the problem of forgings being stuck in the round hole and difficult to remove after upsetting due to the increased cross-sectional area.

[0007] The technical solution adopted by this application to solve its technical problem is: an upsetting machine for forging, comprising:

[0008] Base;

[0009] A support assembly is mounted on the base. The support assembly includes a feeding frame mounted on the base. One end of the feeding frame is provided with a feeding hole. An upper pressure plate and a lower pressure plate slide in the feeding hole. An auxiliary hydraulic cylinder is mounted on the lower end of the base. A support plate is mounted on the output end of the auxiliary hydraulic cylinder. A support seat is mounted on the support plate. An adapter plate connected to the support plate is mounted on the lower pressure plate.

[0010] An anti-deviation component is installed on the feeding frame. The anti-deviation component drives the upper pressure plate and the lower pressure plate to move relative to or away from each other, which is suitable for preventing the forging from deviating during the upsetting process.

[0011] Furthermore, guide grooves are provided on both sides of the discharge hole, and guide blocks adapted to the guide grooves are installed on both sides of the upper pressure plate and the lower pressure plate.

[0012] Furthermore, the upper pressure plate is located above the lower pressure plate.

[0013] Furthermore, the anti-deviation component includes two sets of rotating shafts rotatably connected to the feeding frame, and toothed cylinders are mounted on the rotating shafts;

[0014] A first long rod is installed on the upper pressure plate, and first toothed plates that mesh with the toothed cylinder are installed on both sides of the first long rod. A second long rod is installed on the lower pressure plate, and second toothed plates that mesh with the toothed cylinder are installed on the second long rod.

[0015] Furthermore, the rotating shafts are symmetrically distributed on the feeding frame.

[0016] Furthermore, the second toothed plate and the first toothed plate are located on opposite sides of the toothed cylinder, which is suitable for forming a symmetrical meshing structure.

[0017] Furthermore, limit blocks are installed on both sides of the first long rod and the second long rod, and limit grooves adapted to the limit blocks are provided on both sides of the feeding frame.

[0018] The beneficial effects of this application are as follows: In the upsetting machine for forging provided by this application, through the cooperation of the support component and the anti-deviation component, the linkage between the support seat and the upper and lower pressure plates can be realized by the auxiliary hydraulic cylinder to stably support and clamp the forging. At the same time, the upper and lower pressure plates can be driven to move relative to each other or in opposite directions by the anti-deviation component, which can effectively prevent the forging from shifting during upsetting. It can also facilitate the picking and putting of the forging when moving in opposite directions, solve the problem of material jamming, and improve the upsetting accuracy and efficiency.

[0030] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0032] like Figures 1-3 As shown, this application provides an upsetting machine for forging, including an upsetting assembly 1. This upsetting assembly 1 is the power core of the entire equipment, used to provide the impact force required for upsetting the forging. It includes a base 11, which is made of high-strength cast iron and has good stability and load-bearing capacity. Support feet 16 are bolted to the four corners of the lower end face of the base 11. The height of the support feet 16 can be finely adjusted by the bolts to ensure the equipment is placed horizontally.

[0033] Connecting rods 12 are fixedly installed at the four corners of the upper surface of the base 11. The connecting rods 12 are solid round steel and are fixedly connected to the base 11 by welding, capable of withstanding large vertical loads. Connecting plates 13 are fixedly installed at one end of each connecting rod 12. The connecting plates 13 are cut from thick steel plates and are welded to the top of the connecting rods 12 to form a stable portal frame structure. A main hydraulic cylinder 14 is bolted to the center of the lower surface of the connecting plate 13. The main hydraulic cylinder 14 is a double-acting piston hydraulic cylinder, and its cylinder body is tightly connected to the connecting plate 13 by high-strength bolts to ensure that it will not loosen during high-pressure operation. A punch head 15 is bolted to the output end of the main hydraulic cylinder 14. The punch head 15 is made of mold steel, hardened, and its lower end surface is precision ground to ensure flatness during upsetting.

[0034] like Figures 2-6 As shown, a support assembly 2 is installed on the base 11. The main function of the support assembly 2 is to support and clamp the forging, ensuring the stability of the upsetting process. The support assembly 2 includes a feeding frame 21 that is bolted to the upper surface of the base 11. The feeding frame 21 is a box-shaped hollow structure made of welded steel plates. A feeding hole 25 is provided at one end of the feeding frame 21. The size of the feeding hole 25 is designed according to the specifications of common forgings, which can not only meet the placement requirements of the forging, but also reserve sufficient space for the removal of the forging after upsetting.

[0035] An upper pressure plate 26 is slidably installed above the discharge hole 25, and a lower pressure plate 27 is slidably installed below the discharge hole 25. Both the upper pressure plate 26 and the lower pressure plate 27 are made of wear-resistant steel plates, and their opposite sides are provided with arc-shaped grooves (not shown in the figure), which can better fit the surface of the cylindrical forging and improve the clamping effect. Guide grooves 29 are provided on both sides of the discharge hole 25. The guide grooves 29 are designed to be continuous. Guide blocks 291 that are adapted to the guide grooves 29 are fixedly installed on both sides of the upper pressure plate 26 and the lower pressure plate 27. Lubricating grease is applied between the guide blocks 291 and the guide grooves 29 to reduce sliding friction and make the movement of the upper pressure plate 26 and the lower pressure plate 27 smoother.

[0036] A support hole 111 is provided at the lower end of the base 11. The support hole 111 passes through the upper and lower end faces of the base 11. Auxiliary hydraulic cylinders 22 are installed at both ends of the support hole 111 by bolts. The auxiliary hydraulic cylinders 22 are also double-acting hydraulic cylinders and share a hydraulic system with the main hydraulic cylinder 14. Their cylinder bodies are fixed to the lower end face of the base 11 by bolts. The installation position is calibrated to ensure the verticality of the output shaft. Support plates 23 are installed at the output ends of the auxiliary hydraulic cylinders 22 by bolts. The support plates 23 are rectangular steel plates with good bending resistance. The support plates 23 can pass through the support hole 111 and extend into the feeding frame 21. A support seat 24 is installed at the upper end of the support plate 23 by bolts. The upper end face of the support seat 24 is provided with anti-slip texture (not shown in the figure), which can increase the friction between the forging and the forging and prevent the forging from sliding on the support surface.

[0037] The lower pressure plate 27 is fixedly installed with a transition plate 28. The transition plate 28 is made by forging, which makes it strong and not easily deformed. The transition plate 28 is convex, and its end away from the lower pressure plate 27 is located in the material feeding frame 21 and is connected to the support plate 23 by bolts. This connection method can smoothly transmit the power of the auxiliary hydraulic cylinder 22 to the lower pressure plate 27, so as to realize the lifting and lowering movement of the lower pressure plate 27.

[0038] like Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, an anti-deviation component 3 is installed on the feeding frame 21. The function of the anti-deviation component 3 is to ensure the synchronous movement of the upper pressure plate 26 and the lower pressure plate 27 and prevent the forging from deviating during the upsetting process. The anti-deviation component 3 includes two sets of rotating shafts 31 rotatably connected to one end of the feeding frame 21. The rotating shafts 31 are symmetrically distributed on the feeding frame 21. A toothed cylinder 32 is installed on the rotating shaft 31. The toothed cylinder 32 is connected to the rotating shaft 31 by a key.

[0039] A first long rod 33 is fixedly installed on the upper pressure plate 26. The first long rod 33 is a square long steel pipe and is fixed to the upper pressure plate 26 by welding. A first toothed plate 34 that meshes with the toothed cylinder 32 is fixedly installed on both sides of the first long rod 33. The first toothed plate 34 is long and strip-shaped, and its tooth profile parameters match those of the toothed cylinder 32. A second long rod 35 is fixedly installed on the lower pressure plate 27. The structure of the second long rod 35 is the same as that of the first long rod 33. A second toothed plate 36 that meshes with the toothed cylinder 32 is installed on the second long rod 35. The second toothed plate 36 and the first toothed plate 34 are located on both sides of the toothed cylinder 32, forming a symmetrical meshing structure.

[0040] Limiting blocks 37 are fixedly installed on both sides of the first long rod 33 and the second long rod 35. The limiting blocks 37 are square and are welded to the long rods. Limiting grooves 38 that are adapted to the limiting blocks 37 are provided on both sides of the feeding frame 21. The length of the limiting grooves 38 limits the range of movement of the long rods. When the limiting blocks 37 contact the end of the limiting grooves 38, they can prevent the long rods from continuing to move, thus preventing the first toothed plate 34 and the second toothed plate 36 from disengaging from the toothed cylinder 32.

[0041] In specific operation, when the lower pressure plate 27 moves upward under the drive of the auxiliary hydraulic cylinder 22, the second long rod 35 fixed on the lower pressure plate 27 moves upward accordingly. The second toothed plate 36 on the second long rod 35 meshes with the toothed cylinder 32, causing the toothed cylinder 32 to rotate around the rotating shaft 31. Since the toothed cylinder 32 meshes with the first toothed plate 34 at the same time, the first toothed plate 34 will move downward under the drive of the toothed cylinder 32, thereby causing the first long rod 33 and the upper pressure plate 26 to move downward. This achieves the synchronous approach of the upper pressure plate 26 and the lower pressure plate 27, symmetrically clamping the forging and effectively preventing the forging from shifting during the upsetting process.

[0042] When it is necessary to release the forging, the lower pressure plate 27 moves downward under the drive of the auxiliary hydraulic cylinder 22, and drives the toothed cylinder 32 to rotate in the opposite direction through the second toothed plate 36. The toothed cylinder 32 then drives the upper pressure plate 26 to move upward through the first toothed plate 34. The upper pressure plate 26 and the lower pressure plate 27 separate synchronously, providing sufficient space for the removal of the forging. During the entire movement, the limiting blocks 37 on both sides of the first long rod 33 and the second long rod 35 slide in the limiting groove 38, ensuring the linearity of the long rod movement.

[0043] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
