Description

Technical Field

[0001] This invention relates to the field of forging press technology, specifically to a forging press for quick positioning and anti-drop forging of forgings. Background Technology

[0002] A forging press is an indispensable piece of equipment in forging production. Its main function is to apply pressure to plastically deform metal billets within a die, thereby obtaining the desired shape and size. It not only improves the mechanical properties of metals, such as strength and toughness, but also ensures product consistency and precision, increases production efficiency, and saves materials. During the forging process, the forging press, in conjunction with the die, ensures that the metal billet is subjected to precisely controlled pressure at high temperatures to achieve the ideal deformation effect. The structure of this type of forging press mainly includes the press body, pressure head, slide block, worktable, hydraulic system, and control system. The press body, as the main supporting part, bears the overall weight of the equipment and the enormous pressure applied during the forging process. The pressure head and slide block work together to transmit pressure to the metal billet, completing its deformation. The worktable is used to hold the billet and die, ensuring stability during processing. The hydraulic system provides power and controls the movement and pressure of the press head to ensure the accuracy of the forging process. For example, a forging press protective structure disclosed in authorization announcement number CN219724461U includes a protective cover installed outside the press head and driven by the press head. The protective cover descends before the press head and rises synchronously with it when the press head rises. A buffer assembly is installed on the protective cover to reduce the impact force of its descent. The protective cover has clearance openings to allow space for external clamping equipment. Rubber plates are symmetrically installed inside the clearance openings. During forging, the protective cover moves with the press head and does not affect the worker's placement of the forging workpiece. The height of the protective cover does not need to be adjusted when the press head's stroke changes. However, in the above technical solution, the protective cover rises and falls with the press head. When the forging press is working, the press head and die apply enormous pressure to the metal billet. During the rapid plastic deformation of the metal billet within the die, a certain amount of vibration and reaction force is generated. These vibrations can cause changes in the relative position between the metal part and the mold. The metal billet may shift or tilt in a certain direction. Only when the protective cover and pressure head are fully raised can the external robotic arm or workers adjust the position of the metal part. Since the operator must wait for the pressure head and protective cover to be fully raised after each forging before making adjustments, this causes delays in the production process. Especially in mass production, adjusting the position of the workpiece after each forging wastes a lot of time, affecting production efficiency and slowing down the work pace. Summary of the Invention

[0003] The purpose of this invention is to provide a forging press for rapid positioning and anti-drop forging process. The metal part to be forged is placed on the worktable. When the press head of the forging press applies enormous pressure to the metal part and the worktable, the metal part and the worktable move downwards and are blocked by the platform, allowing the metal part to be impacted and forged. During this process, the downward movement of the worktable is transmitted to the self-lifting anti-drop structure through a gear and rack transmission structure, so that the self-lifting anti-drop structure protects the front and rear sides of the worktable. After the press head moves upwards, the self-lifting anti-drop structure resets. Furthermore, a pneumatic bidirectional push-pull unit brings the two longitudinal positioning beams closer together, helping the offset metal part to automatically center itself, thus solving the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a forging press for rapid positioning and anti-drop forging, comprising:

[0010] Preferably, the elastic unit includes a T-shaped longitudinal arm fixed to the top of the upright plate and a hydraulic damper fixed to the inner wall of one side of the side frame. A protruding post is fixed on the outer wall of the upright plate near the side frame, and the top end of the piston rod of the hydraulic damper is fixedly connected to one end of the protruding post.

[0011] Preferably, the self-tilting anti-fall structure includes a long U-shaped shaft frame fixed between the two side frames in the same X-axis direction, a secondary drive shaft rotatably installed inside the long U-shaped shaft frame, and a spoon plate fixed at one end of the surface of the secondary drive shaft. A protective plate is fixed on the outer wall of the spoon plate on the side away from the secondary drive shaft. The self-tilting anti-fall structure also includes a bevel gear transmission structure installed between the opposite ends of the secondary drive shaft and the main drive shaft.

[0012] Preferably, the bevel gear transmission structure includes a driving bevel gear fixed at one end of the main drive shaft and a driven bevel gear disk fixed at one end of the auxiliary drive shaft, wherein the driven bevel gear disk and the driving bevel gear mesh with each other.

[0013] Preferably, two symmetrical horizontal plates are slidably installed on the inner wall of one side of the right-angled floor platform via guide rails and sliding tables, and a rectangular rib is fixed on the upper surface of the horizontal plate. A U-shaped block is provided at the position where the top of the rectangular rib contacts the longitudinal positioning beam, and the top of the U-shaped block is fixedly connected to the bottom of the longitudinal positioning beam.

[0014] Preferably, the longitudinal positioning beam has a right-angle chamfer on the outer wall of the side closest to the vertical center reference plane of the workbench.

[0015] Preferably, the pneumatic bidirectional push-pull unit includes a platform fixed to the bottom of the workbench, two symmetrical lower right-angle mating plates slidably mounted on the lower surface of the platform, and a main shaft rotatably mounted at the center of the bottom of the platform. A central gear is fixed to the bottom of the main shaft. A protruding plate is integrally formed on the outer wall of the two lower right-angle mating plates that are close to each other. A second rack is fixed on the outer wall of the two protruding plates that are close to each other. The second rack and the central gear mesh with each other.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: This forging press for quick positioning and anti-drop forging press for forging parts is constructed by setting up a press head, a workpiece table, a gear and rack transmission structure, a self-flipping anti-drop structure, and a pneumatic bidirectional push-pull unit, among other mutually cooperating structures. Under the pressure of the press head, the workpiece table moves downward and is blocked by the table base. This process allows the metal part to be forged. This movement is achieved through the gear and rack transmission structure, which ensures that the downward movement of the workpiece table and the front and rear protection of the self-flipping anti-drop structure are completed synchronously. The design of the self-flipping anti-drop structure ensures that the metal part is protected during the downward movement of the workpiece table. The billet is always protected from front and rear to prevent it from falling due to vibration, misalignment, or mechanical failure, thus protecting the safety of workers. After the pressure head moves up, the self-folding anti-fall structure will quickly reset. At the same time, through the pneumatic bidirectional push-pull unit, the two longitudinal positioning beams automatically approach each other to help the metal parts that have shifted to a different position to automatically center. During this process, the workers can quickly adjust the position of the metal parts while the pressure head moves up, and make the shifted metal parts quickly return to the predetermined position. This greatly shortens the adjustment time after each forging, thereby reducing the idle time of the forging equipment and improving the overall production efficiency. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0028] Example 1, by Figures 1 to 3 The present invention includes a right-angled open-type base 1, and two right-angled open-type base 1s are provided. Side frames 2 are fixed on the front and rear sides of the two right-angled open-type base 1s. A worktable 4 is slidably installed on the inner wall of the side of the two right-angled open-type base 1s that are close to each other. L-shaped long arms 5 are integrally formed at the corners of the left and right outer walls of the worktable 4. The end of the L-shaped long arm 5 away from the worktable 4 is slidably connected to the inner wall of the right-angled open-type base 1 through a guide rail and a slide table. An elastic unit that forces the worktable 4 to move upward is installed on the inner wall of the side frame 2 that is close to the worktable 4.

[0029] The platform 101 is fixed to the bottom of the right-angled hollow base 1. A gap is provided between the top of the platform 101 and the bottom of the worktable 4. A self-flipping anti-falling structure 12 is provided between the two side frames 2 in the same X-axis horizontal direction to prevent the workpiece on the worktable 4 from sliding out. A gear and rack transmission structure 8 that maintains power transmission with the self-flipping anti-falling structure 12 is provided on the outer wall of the L-shaped long arm 5 near the side frame 2.

[0030] The pneumatic bidirectional push-pull unit 11 is installed on the lower surface of the worktable 4. Both movable ends of the pneumatic bidirectional push-pull unit 11 are equipped with longitudinal positioning beams 10, which are located between two L-shaped long arms 5 in the same Y-axis direction.

[0031] Example 2, based on Example 1, is... Figure 4 , Figure 5 and Figure 6As shown, a Y-shaped locking block 6 is bolted to the outer wall of the L-shaped long arm 5 near the side frame 2, and an upwardly extending vertical plate 7 is fixed to the outer wall of the Y-shaped locking block 6 away from the right-angled open-type base 1. A gear and rack transmission structure 8 is set on the outer wall of one side of the vertical plate 7. The outer wall of the Y-shaped locking block 6 near the side frame 2 is slidably connected to the inner wall of one side of the side frame 2 through a guide rail and a slide table.

[0032] During the process of the worktable 4 and the workpiece being pressed down by the pressure head and moving close to the base 101, the corners of the worktable 4 drive the L-shaped long arm 5, the Y-shaped locking block 6, and the upright plate 7 to move down together. The end of the L-shaped long arm 5 away from the worktable 4 slides with the right-angle hollow base 1 through the guide rail and the slide table, while the end of the Y-shaped locking block 6 away from the L-shaped long arm 5 also slides with the side frame 2 through the guide rail and the slide table. At this time, the elastic unit is in the compression stage. The L-shaped long arm 5 and the Y-shaped locking block 6 improve the lifting stability of the worktable 4 and compensate for the forging deviation caused by the error of the pressure head and the workpiece.

[0033] The gear and rack transmission structure 8 includes a main drive shaft 802 rotatably mounted inside the base 101, a rack unit 801 fixed on the outer wall of one side of the vertical plate 7, and a driven gear 803 fixed to one end of the main drive shaft 802. The driven gear 803 and the rack unit 801 mesh with each other. During the downward movement of the vertical plate 7, the vertical plate 7 will actively drive the rack unit 801 to move downward. The downward pressing action of the rack unit 801 is converted into the rotational motion of the main drive shaft 802 through the driven gear 803. The gear and rack have a large contact area and can withstand a large load. They are suitable for working in high-load and high-pressure environments and have good load-bearing capacity.

[0034] The elastic unit includes a T-shaped longitudinal arm 804 fixed to the top of the vertical plate 7 and a hydraulic damper 3 fixed to the inner wall of one side of the side frame 2. A protruding column is fixed on the outer wall of the vertical plate 7 near the side frame 2. The top of the piston rod of the hydraulic damper 3 is fixedly connected to one end of the protruding column. When a collision or vibration occurs, the hydraulic damper 3 can effectively control the system's reaction speed through the liquid damping effect, avoiding excessive oscillation or shaking of the system. At the same time, under high dynamic load, the hydraulic damper 3 can effectively prevent system instability caused by excessive vibration or instantaneous impact, ensuring the long-term reliable operation of the forging table.

[0035] The self-tipping anti-fall structure 12 includes a long U-shaped shaft frame 1201 fixed between two side frames 2 in the same X-axis direction, a secondary drive shaft 1202 rotatably installed inside the long U-shaped shaft frame 1201, and a spoon plate 1204 fixed at one end of the surface of the secondary drive shaft 1202. A protective plate 1205 is fixed on the outer wall of the spoon plate 1204 away from the secondary drive shaft 1202. The self-tipping anti-fall structure 12 also includes a bevel gear transmission structure 1203 installed between the opposite ends of the secondary drive shaft 1202 and the main drive shaft 802. The bevel gear transmission structure 1203 includes a driving bevel gear fixed at one end of the main drive shaft 802 and a driven bevel gear disk fixed at one end of the secondary drive shaft 1202. The driven bevel gear disk and the driving bevel gear mesh with each other.

[0036] The main drive shaft 802 uses the bevel gear transmission structure 1203 to drive the auxiliary drive shaft 1202 to rotate actively. At this time, the auxiliary drive shaft 1202 drives the spoon plate 1204 and the protective plate 1205 to swing upward. During the process of the pressure head, worktable 4 and workpiece moving downward, the protective plate 1205 actively rises and falls and forms a barrier to prevent the workpiece from shifting due to excessive impact pressure and to prevent the workpiece from falling off the worktable 4. This structure can be adjusted according to the size and shape of different workpieces to ensure that the workpiece can be effectively prevented from falling under various working conditions and to ensure the safety of the production environment.

[0037] Example 3, based on Example 2, by Figure 7 and Figure 8 It is given that the longitudinal positioning beam 10 has a right-angle chamfer on the outer wall of the side near the vertical center reference plane of the workbench 4, and two symmetrical horizontal plates 9 are slidably installed on the inner wall of the side of the right-angle open-type base 1 via guide rails and slides. The upper surface of the horizontal plate 9 is fixed with a rectangular rib. A U-shaped block is set at the position where the top of the rectangular rib contacts the longitudinal positioning beam 10, and the top of the U-shaped block is fixedly connected to the bottom of the longitudinal positioning beam 10.

[0038] When the longitudinal positioning beam 10 moves in the X-axis direction, both ends of it are slidably connected to the L-shaped long arm 5 through guide rails and slides. When the longitudinal positioning beam 10 moves together with the worktable 4 in the Z-axis direction, the longitudinal positioning beam 10 will drive the horizontal plate 9 to rise and slide together. The bottom end of the longitudinal positioning beam 10 and the top end of the horizontal plate 9 are also kept in a sliding state through guide rails and slides, so that the longitudinal positioning beam 10 is more stable when it moves.

[0039] The pneumatic bidirectional push-pull unit 11 includes a hanging platform 1101 fixed to the bottom of the workbench 4, two symmetrical lower right-angle mating plates 1102 slidably mounted on the lower surface of the hanging platform 1101, and a main shaft 1103 rotatably mounted at the center of the bottom end of the hanging platform 1101. A central gear 1106 is fixed to the bottom end of the main shaft 1103. A protruding plate 1104 is integrally formed on the outer wall of the side where the two lower right-angle mating plates 1102 are close to each other. Both protruding plates 1104 have a protruding plate 1104 on the outer wall of the side where they are close to each other. A second rack 1105 is fixed, and the second rack 1105 and the central gear 1106 mesh with each other. A cylinder 1107 is installed at the bottom of the lifting platform 1101. A boss is fixed at the top of the piston rod of the cylinder 1107. The bottom end of the boss is fixedly connected to the top end of one of the lower right-angle connecting plates 1102. The top end of the lower right-angle connecting plate 1102 is fixedly connected to the bottom end of the longitudinal positioning beam 10. A U-shaped notch is provided on one side of the bottom of the lifting platform 1101 for the boss to slide in the X-axis direction.

[0040] During the process of the worktable 4 and the workpiece being pushed upward by the hydraulic damper 3, the operator can activate the cylinder 1107 to work. The cylinder 1107 pulls one of the lower right-angle docking plates 1102 towards the main shaft 1103. Since the two symmetrical lower right-angle docking plates 1102 are connected by the second rack 1105 and the central gear 1106, the two lower right-angle docking plates 1102 and the longitudinal positioning beam 10 can approach each other. The longitudinal positioning beam 10 actively forces the workpiece to center itself, keeping the workpiece in the accurate position for forging operations. This can effectively shorten the workpiece clamping time and reduce manual adjustment errors.

[0041] In this embodiment, before the forging process begins, the metal part to be forged is placed on the worktable 4. The worktable 4 has sufficient stability and load-bearing area. The workpiece is placed in the center of the worktable 4 to ensure that it will not tilt or shift under the action of the pressure head. When the pressure head begins to move downward and apply pressure, the metal part on the worktable 4 is pressed down. At this time, the worktable 4 and the metal part move down together until the bottom of the worktable 4 hits the top of the base 101. The base 101 prevents the worktable 4 and the metal part from moving down excessively, avoiding damage to the elastic unit due to excessive impact force. The downward movement of the worktable 4 in this stage is transmitted to the self-tilting anti-falling structure 12 through the gear and rack transmission structure 8. That is, while the metal part is impacted and forged by the pressure head, the downward movement of the worktable 4 causes the self-tilting anti-falling structure 12 to automatically unfold and protect the front and rear sides of the metal part. The self-tilting anti-falling structure 12 ensures that the metal part will not fall or shift due to vibration or uneven pressure, and also protects the front and rear sides of the workpiece. The anti-fall structure provides robust protection, preventing the billet from becoming unstable and falling off when subjected to external impact. When the pressure head begins to move upward, the elastic unit actively pushes the worktable 4 and the metal workpiece upward, and then the self-flipping anti-fall structure 12 actively resets. Simultaneously, the pneumatic bidirectional push-pull unit 11 adjusts the position of the longitudinal positioning beam 10, causing the two longitudinal positioning beams 10 to move closer together. This allows the metal part to automatically center itself during the pressure head's upward movement, restoring it to the correct centering position. During this process, the pneumatic bidirectional push-pull unit 11 has precise control capabilities. Through the power of compressed gas, it can adjust the positioning beams in a very short time, ensuring that the two longitudinal positioning points of the metal part remain in the correct position. This avoids the risk of quality problems or improper operation caused by the metal part's misalignment. Through the synergistic effect of the longitudinal positioning beam 10 and the self-flipping anti-fall structure 12, the metal part is prevented from falling while also avoiding unexpected positional changes due to vibration, impact, or other factors. This improves production efficiency and ensures operational safety and forging quality during the forging process.
