Description

Technical Field

[0001] This utility model belongs to the field of hydraulic press technology, and in particular relates to a fast forging hydraulic press with a swing arm billet forming function. Background Technology

[0002] Currently, two-column presses are preferred for shaft-type products, while four-column hydraulic presses are preferred for ring forgings. Both types of presses can process each other, but production efficiency will be affected. Currently, ring forging blanks are prepared using either four-column or two-column hydraulic presses: Method 1 uses a four-column press to roughen, center, and punch holes in the round ingot in one pass; Method 2 uses a two-column press for multiple upsetting and drawing operations, followed by manual or overhead crane punching. Both methods have drawbacks: for products requiring high internal material structure, multiple upsetting and drawing operations are necessary. When using a four-column press, the operator's visibility is very poor due to obstruction by the centering device and the four-column structure, resulting in very low work efficiency. (See [link to relevant documentation]). Figure 5 If a centering device is installed on the central axis of the press, the operating field of vision will be worse. For two-column presses, in order to avoid interference, a centering device is usually not installed or a centering device and a transverse anvil mechanism are not installed at the same time. Therefore, when pressing with a two-column press, manual or overhead crane punches are required for punching, which is very inefficient. Utility Model Content

[0003] Based on this, and to address the aforementioned technical problems, a high-speed forging hydraulic press with a swing arm billet-making function is provided.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A high-speed forging hydraulic press with a swing arm billet-forming function includes a frame, an upper crossbeam, a movable crossbeam, and a base mounted on the frame, a movable walkway whose stroke passes through the center line of the hydraulic press, a hydraulic drive mechanism for driving the movable crossbeam to rise and fall, a centering mechanism for centering the workpiece to be forged to the center of the hydraulic press, an upper punch, an upper swing arm mechanism for driving the upper punch to swing horizontally to the center, a lower punch, and a lower swing arm mechanism for driving the lower punch to swing horizontally to the center. The movable walkway is mounted on the base, and the hydraulic drive mechanism is mounted on the upper crossbeam. The upper swing arm mechanism and the lower swing arm mechanism are respectively mounted on the movable crossbeam and the base. The feature is that it also includes a transverse anvil-moving mechanism whose stroke passes through the center line of the hydraulic press. The frame is a two-column type, and the angle α between the line connecting the centers of the two columns and the width direction of the movable platform is 30°-40°. The centering mechanism is mounted on the two columns, and its centering direction is parallel to the line connecting the centers. The transverse anvil-moving mechanism is mounted on the base and is arranged at a 90° angle to the movable platform. One of the tracks has a gap for the other to pass horizontally.

[0006] This utility model adopts a two-column structure and is equipped with a movable platform, a centering mechanism, and a transverse anvil mechanism. It can realize fast forging, centering, and punching blank making. The centering mechanism is set on two pillars and can center along the line connecting the centers of the two pillars. At the same time, the angle between the width of the movable platform and the line connecting the centers of the two pillars is 30°-40°, and the transverse anvil mechanism is arranged at a 90° intersection with the movable platform. This not only does not affect the field of vision, but also avoids interference between the movable platform, the centering mechanism, and the transverse anvil mechanism, thus improving work efficiency.

[0012] The embodiments of this utility model will be described below with reference to the accompanying drawings. It should be noted that the embodiments described in this specification are not exhaustive and do not represent the only embodiments of this utility model. The following corresponding embodiments are only for clearly illustrating the utility model content of this patent and are not intended to limit its implementation. For those skilled in the art, different variations and modifications can be made based on the described embodiments. Any obvious variations or modifications that fall within the technical concept and utility model content of this utility model are also within the protection scope of this utility model.

[0013] like Figure 1-3 As shown in the figure, this application provides a fast forging hydraulic press with a swing arm billet forming function, including a frame 1100, an upper crossbeam 1200, a movable crossbeam 1300, a base 1400, a hydraulic drive mechanism 1500, a moving platform 1600, a centering mechanism 1700, an upper punch 1800, an upper swing arm mechanism 1900, a lower punch 1997, a lower swing arm mechanism 1998, and a transverse anvil moving mechanism 1999.

[0014] The frame 1100 adopts a two-column design, that is, it has two support columns 1110.

[0015] like Figure 1 As shown, each column 1110 is a hollow column with a horizontal through hole 1111. The center line of the through hole 1111 coincides vertically with the line connecting the centers of the two columns 1110. The through hole 1111 is elongated in the vertical direction.

[0016] The upper crossbeam 1200, the movable crossbeam 1300 and the base 1400 are arranged from top to bottom. The upper crossbeam 1200 is fixed between the upper ends of the two columns 1110. The two ends of the movable crossbeam 1300 form guide grooves, which slide with the column 1110. The base 1400 is fixed between the lower ends of the two columns 1110.

[0017] The hydraulic drive mechanism 1500 is used to drive the movable crossbeam 1300 to rise and fall; it is mounted on the upper crossbeam 1200. Figure 1 As shown, it includes a main cylinder 1510 and two return cylinders 1520. The piston rod of the main cylinder 1510 extends downward and is connected to the middle of the movable crossbeam 1300 by bolts. The two return cylinders 1520 are symmetrically located on the left and right sides of the main cylinder 1510. The piston rods of the two return cylinders 1520 extend downward and are connected to the left and right sides of the movable crossbeam 1300 by bolts.

[0018] The movable platform 1600 is mounted on the base 1400 and can be replaced with different worktables as needed, such as an upsetting table, a drop plate, etc. The horizontal travel of the worktable passes through the center line (vertical) of the hydraulic press. As shown in the figure, the length direction of the movable platform 1600 is the front-to-back direction, and the width direction is the left-to-right direction. The angle α between this width direction and the line connecting the centers of the two support columns 1110 is 30° to 40°, providing a wider field of vision for the operator in the control room. See [reference needed]. Figure 4 In this embodiment, the included angle α is 35°.

[0019] The centering mechanism 1700 is used to center the workpiece to be forged (such as a steel ingot) to the center of the hydraulic press. Centering reduces punching deviation and defects. Its centering direction is parallel to the line connecting the centers of the two supports 1110. Figure 1-3 As shown, the centering mechanism 1700 includes centering units 1710 respectively disposed on two columns 1110. The centering unit 1710 includes a sliding sleeve 1711, a lifting module 1712, a linear module 1713 and a clamp 1714.

[0020] The sliding sleeve 1711 slides up and down onto the corresponding column 1110.

[0021] The lifting module 1712 is fixed inside the corresponding column 1110.

[0022] The linear module 1713 passes through the through hole 1111 of the corresponding column 1110 and is used to drive the chuck 1714 to move horizontally and linearly along the center line connecting the two columns 1110. The direction in which it drives the chuck 1714 to move is the centering direction of the centering mechanism 1700.

[0023] The linear module 1713 is connected to the sliding sleeve 1711, and the sliding sleeve 1711 slides up and down with the corresponding column 1110. The linear module 1713 is also connected to the lifting module 1712, and can be raised and lowered under the drive of the lifting module 1712.

[0024] The chuck 1714 is connected to the linear module 1713, and its clamping surface is arc-shaped in the horizontal direction.

[0025] Both the lifting module 1712 and the linear module 1713 use hydraulic cylinders.

[0026] like Figure 3 As shown, the upper punch 1800 is fixed on the upper swing arm mechanism 1900, which is mounted on the movable crossbeam 1300. Driven by the upper swing arm mechanism 1900, the upper punch 1800 can be horizontally swung to the center of the hydraulic press.

[0027] like Figure 2 As shown, the lower punch 1997 is fixed on the lower swing arm mechanism 1998, which is mounted on the base 1400. Driven by the lower swing arm mechanism 1998, the lower punch 1997 can be horizontally swung to the center of the hydraulic press.

[0028] It should be noted that both the upper swing arm mechanism 1900 and the lower swing arm mechanism 1998 are conventional mechanisms, and their specific structures are not limited here.

[0029] The horizontal moving anvil mechanism 1999 is set on the base 1400 and is used to move the anvil horizontally. Different types of anvils can be replaced as needed, such as flat anvils, chopping anvils, and arc anvils, etc. The stroke of the anvil passes through the center line of the hydraulic press.

[0030] like Figure 4 As shown, the transverse anvil mechanism 1999 and the moving platform 1600 are arranged at a 90° angle, that is, its length direction (moving direction) forms a 35° angle with the centering direction of the centering mechanism 1700. Furthermore, the track of either the transverse anvil mechanism 1999 or the moving platform 1600 has a break for the other to pass horizontally. This arrangement ensures that the transverse anvil mechanism 1999 does not interfere with either the moving platform 1600 or the centering mechanism 1700 during operation. In this embodiment, the track of the transverse anvil mechanism 1999 has a break for the moving platform 1600 to pass horizontally.

[0031] The process for manufacturing the ring forging in this embodiment of the application is as follows:

[0032] 1. The movable platform 1600 moves the worktable 2 to the center of the hydraulic press. The movable crossbeam 1300 is raised and lowered under the drive of the hydraulic drive mechanism 1500, and in conjunction with the manipulator of the operating machine, the steel ingot 3 is upset, drawn, and then upset again to form a disc-shaped forging 4, which is placed on the worktable 2. (See below) Figure 1 and Figure 2 .

[0033] 2. The centering mechanism 1700 centers the disc-shaped forging 4 on the worktable 2 and clamps it, raising it to the first position above the lower punch 1997. (See below) Figure 2 The first position refers to the position 20mm above the lower punch 1997.

[0034] 3. The lower swing arm mechanism 1998 swings the lower punch 1997 to the center of the hydraulic press directly above the worktable 2. The centering mechanism 1700 clamps the disc-shaped forging 4 and drops it onto the lower punch 1997. The movable crossbeam 1300 presses down on the disc-shaped forging 4, and the lower punch 1997 is forced into the disc-shaped forging 4. During this process, the center of the disc-shaped forging is not pressed through, and the thickness of the unpressed part is about 30 to 50 mm. The lower punch 1997 is the main punch. In the prior art, the upper punch is used as the main punch for the pressing process, that is, the upper punch hole is deeper, and the lower punch is only an auxiliary or not set.

[0035] 4. The centering mechanism 1700 clamps the disc-shaped forging 4 and raises it to a position 20mm above the lower punch 1997. At the same time, the lower swing arm mechanism 1998 swings the lower punch 1997 away from the center of the hydraulic press.

[0036] 5. A worktable 5 with a center hole is placed on the transverse anvil-shifting mechanism 1999. The transverse anvil-shifting mechanism 1999 moves the worktable 5 to the center of the hydraulic press. At the same time, the moving platform 1600 moves the worktable 2 away from the center of the hydraulic press. The centering mechanism 1700 clamps the disc-shaped forging and lowers it onto the worktable 5, then releases the disc-shaped forging. The upper swing arm mechanism 1900 swings the upper punch 1800 to the center of the hydraulic press. The movable crossbeam 1300, carrying the upper punch 1800, presses down on the disc-shaped forging, punching through the center of the disc-shaped forging to form a ring-shaped forging. See [link to relevant documentation]. Figure 3 .

[0037] The fast forging hydraulic press of this application embodiment can not only efficiently complete the manufacturing of ring forgings, but also complete ordinary free forging manufacturing.

[0038] As can be seen from the above, the fast forging hydraulic press with swing arm billet-making function provided in this application adopts a two-column structure and is equipped with a moving platform, a centering mechanism, and a transverse anvil-moving mechanism. It can realize fast forging function, as well as centering and punching billet-making. The centering mechanism is set on two pillars and can center along the line connecting the centers of the two pillars. At the same time, the angle between the width direction of the moving platform and the line connecting the centers of the two pillars is 35°-40°, and the transverse anvil-moving mechanism is arranged at a 90° intersection with the moving platform. This not only does not affect the field of vision, but also avoids interference between the moving platform, the centering mechanism, and the transverse anvil-moving mechanism, thus improving work efficiency.

[0039] Obviously, those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any changes or modifications to the above embodiments within the essential spirit of the present utility model will fall within the scope of the claims of the present utility model.
