Abstract
Description
Technical Field
[0001] The present application relates to the technical field of mechanical processing equipment, and in particular to an equipment suitable for conventional forging and multi-directional die forging and a method for using the same. Background Art
[0002] Multi-directional die forging is an advanced forging process, typically performed on a multi-directional hydraulic press. Compared to conventional die forging (unidirectional die forging) and split die forging, multi-directional die forging offers significant advantages. Multi-directional die forging is capable of producing high-quality hollow and complex-shaped parts with complex structures, such as hollow frames, pistons, shafts, cylindrical parts, and large valve bodies. Furthermore, the die forging process improves material utilization, reduces machining time, and contributes to enhanced mechanical properties.
[0003] Multi-directional die forging equipment comes in various forms. Since it adds a horizontal load mechanism compared to traditional presses, the structure of existing die forging equipment is relatively complex, such as the three-beam and four-column structure of the U-shaped lower crossbeam, the vertical and horizontal independent frame structure, the overall plate and frame combination structure and the wire winding structure, etc., to meet different needs.
[0004] Multi-directional die forging equipment based on independent horizontal frames: During the multi-directional die forging process, vertical and horizontal loads need to be borne by two frames that do not interfere with each other. Generally, there are two design options. One is that the horizontal frame surrounds the vertical frame, which is bulky and expensive. The other is that the horizontal frame passes through the vertical frame, which will weaken the strength of the vertical frame. In addition, the horizontal frame is often in an eccentric stress state, reducing the product dimensional accuracy and equipment service life.
[0005] Multi-directional die forging equipment based on an integral frame: During the multi-directional die forging process, vertical and horizontal loads are simultaneously borne by an integral frame. However, the integral frame is subjected to complex forces, has high strength requirements, and has high requirements on the performance of the frame material. The processing difficulty increases accordingly, and therefore the maximum tonnage of the equipment will also be limited.
[0006] Therefore, when arranging the horizontal load mechanism of the existing multi-directional die forging equipment, there are problems such as large size, high frame strength requirements and short frame life caused by unreasonable arrangement. Summary of the Invention

DETAILED DESCRIPTION
[0046] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the devices of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.
[0047] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application as claimed, but merely represents selected embodiments of the present application. It should be noted that, unless there is a conflict, the various features of the embodiments of the present application may be combined with each other, and the combined embodiments are still within the scope of protection of the present application.
[0048] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.
[0049] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the product of this application is typically placed when in use. These terms are intended only to facilitate the description of this application and simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0050] Furthermore, terms such as "horizontal" and "vertical" do not necessarily mean that a component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.
[0051] It should also be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.
[0052] In one aspect of the embodiments of the present application, there is provided a device suitable for conventional forging and multi-directional die forging (hereinafter referred to as forging device), such as Figure 1 or Figure 2 As shown, it includes a base 12, a mold base 14 and a horizontal pressurizing device 89. Figure 1 or Figure 2 The mold base 14 is fixedly mounted on the base 12, and a number of horizontal pressure devices 89 are distributed around the mold base 14, such as Figure 1 or Figure 2In the figure, four horizontal pressurizing devices 89 are distributed one by one on the front, back, left and right sides of the die base 14. Of course, in an embodiment not shown, the horizontal pressurizing devices 89 can also be distributed only on the left and right sides or the front and back sides of the die base 14. At the same time, it should be understood that this application does not limit the number of horizontal pressurizing devices and their distribution positions around the die base 14. For example, on a circle centered on the die base 14, several horizontal pressurizing devices can be distributed at any position on the circumference. In order to facilitate the forging of the first blank in the die base 14 by the horizontal pressurizing devices 89, a horizontal die 13 can be installed at the driving end of each horizontal pressurizing device 89, and the horizontal die 13 can directly act on the first blank, thereby forging the first blank. When the number of horizontal pressurizing devices is at least two, the first blank can be forged horizontally from multiple directions.
[0053] Please continue to refer to Figure 1 or Figure 2 The mold base 14 has an inner cavity 16, and in order to facilitate the addition of materials, an opening 25 communicating with the inner cavity 16 can be opened on the top of the mold base 14. A number of first through holes 17 communicating with the inner cavity 16 are opened on the side wall of the mold base 14. The purpose of the first through holes 17 is to facilitate the passage of the horizontal mold 13. Therefore, the number of the first through holes 17 can be reasonably set according to the number of the horizontal pressurizing devices 89. For example, a number of first through holes 17 corresponds to a number of horizontal pressurizing devices 89 one by one, so that the horizontal mold 13 at the driving end of each horizontal pressurizing device 89 can smoothly pass through its corresponding first through hole 17. For example Figure 1 or Figure 2 In the embodiment, first through holes 17 are provided at the center of the front, rear, left and right side walls of the mold base 14 , so as to correspond one to one with the horizontal pressure devices 89 distributed on the front, rear, left and right sides of the mold base 14 .
[0054] In this way, the horizontal pressurizing device 89 can drive the horizontal die 13 through the first through-hole 17 through the driving end, and then act on the first blank in the inner cavity 16 and pressurize it horizontally. In order to optimize the layout of the horizontal pressurizing device 89, the horizontal pressurizing device 89 can be fixedly connected to the die base 14, for example, the horizontal pressurizing device 89 is fixedly connected to the outer wall of the die base 14, so that when the horizontal pressurizing device 89 pressurizes the first blank horizontally, its horizontal load mainly acts on the die base 14, and has no effect on other structures of the equipment (such as the vertical frame 23 structure), thereby solving the problems existing in the independent horizontal frame and the integral frame in the existing multi-directional die forging equipment, such as the large equipment structure, the weakened structural strength of the vertical frame 23, the complex force of the integral frame, the high material cost and the difficulty in processing, and ensuring the dimensional accuracy and quality of the forgings.
[0055] In some possible embodiments, among the plurality of horizontal pressurizing devices 89, two horizontal pressurizing devices 89 may form a group, and each group of horizontal pressurizing devices 89 is symmetrically distributed on opposite sides of the mold base 14, for example Figure 1 or Figure 2 In the embodiment, the two horizontal pressurizing devices 89 distributed on the front and rear sides of the mold base 14 form a group, and the two horizontal pressurizing devices 89 distributed on the left and right sides of the mold base 14 form a group.
[0056] In some possible implementations, such as Figure 3 or Figure 4 As shown, a boss 22 can be provided on the side wall of the die base 14, and the horizontal pressure device 89 can be fixedly connected to the boss 22, thereby achieving a fixed connection between the horizontal pressure device 89 and the die base 14. In the specific connection, it can be fixed by welding or by bolts, such as Figure 3 In the figure, a plurality of screw holes 21 are provided on the boss 22 in the vertical direction. Similarly, a plurality of screw holes 21 can also be provided on the fixing seat 9 of the horizontal pressurizing device 89. A plurality of bolts are passed through the screw holes 21 on the boss 22 and the fixing seat 9 one by one, thereby fixing the horizontal pressurizing device 89 to the mold base 14.
[0057] In some possible implementations, since the mold base 14 has the inner cavity 16 and the opening 25, the mold base 14 may be in the shape of a Chinese numeral U in a top view, for example: Figure 3 In the figure, the mold base 14 is roughly in the shape of a Chinese numeral U in a top view.
[0058] In some possible implementations, such as Figure 1 or Figure 2 As shown, a die base mounting plate 10 is fixedly mounted on the base 12, and the die base 14 is fixedly mounted to the base 12 via the die base mounting plate 10. Furthermore, a T-slot can be provided on the die base mounting plate 10, and a mounting hole can be provided at a corresponding position on the bottom of the die base 14. T-bolts can be used to connect the mounting hole and the T-slot to secure the die base 14 to the die base mounting plate 10. To facilitate the insertion of the drive end of the ejector device 11, a perforation is provided in the center of the die base mounting plate 10, allowing the drive end of the ejector device 11 to pass through during vertical movement.
[0059] In some possible implementations, such as Figure 1 or Figure 2 As shown, a vertical frame 23 is fixedly provided on the base 12, and a vertical pressurizing device 1 is installed on the vertical frame 23, wherein the vertical pressurizing device 1 is located directly above the mold base 14. In other words, when the driving end of the vertical pressurizing device 1 telescopically moves in the vertical direction, the mold base 14 is in its movement path, so that the driving end of the vertical pressurizing device 1 can move in the direction close to the mold base 14 when moving in the vertical direction, so as to vertically pressurize the first blank or the second blank on the mold base 14.
[0060] In order to obtain the desired forging, an upper die 5 may be installed on the driving end of the vertical pressing device 1 , and the upper die 5 may match the upper profile of the forging obtained by the final die forging.
[0061] On this basis, the forging equipment also includes a one-way die forging component 67 and a multi-directional die forging component that can be replaced on the die base 14. Therefore, according to the die forging requirements, when ordinary die forging is required, such as Figure 1 As shown, the multi-directional die forging assembly (if any) on the die base 14 can be removed, and then the unidirectional die forging assembly 67 can be installed on the die base 14. Then, the second blank in the unidirectional die forging assembly 67 can be vertically pressurized by the vertical pressurizing device 1 in conjunction with the die base 14 to obtain the desired forging. When multi-directional die forging is required, as shown in FIG. Figure 2 As shown, the unidirectional die forging assembly 67 (if any) on the die base 14 can be removed, and then the multidirectional die forging assembly can be installed on the die base 14. Then, the vertical pressurizing device 1 cooperates with the die base 14 to vertically pressurize the first blank in the multidirectional die forging assembly, and then the horizontal pressurizing device 89 mentioned above is used to horizontally pressurize the first blank in the vertical pressurized state, so as to obtain the desired forging. Specifically:
[0062] When ordinary die forging is required, such as Figure 1 As shown, a one-way die forging assembly 67 is fixedly provided on the die base 14, and then the heated second blank is placed in the one-way die forging assembly 67, and the vertical pressurizing device 1 is started (the position of the driving end of the vertical pressurizing device 1 before starting is the initial position), so that the driving end of the vertical pressurizing device 1 drives the upper die 5 to move toward the die base 14, and after the upper die 5 contacts the second blank, it continues to move in the original direction, thereby cooperating with the one-way die forging assembly 67 to vertically pressurize the second blank. After the forging is completed, the second blank forms the required forging, and at this time, the driving end of the vertical pressurizing device 1 can be controlled to move in the opposite direction, thereby driving the upper die 5 to separate from the one-way die forging assembly 67 until the vertical pressurizing device 1 is reset to the initial position.
[0063] When multi-directional forging is required, such as Figure 2As shown, the unidirectional die forging assembly 67 fixed on the die base 14 can be removed, and then a multidirectional die forging assembly can be set on the die base 14. The multidirectional die forging assembly can be placed in the inner cavity 16, and then the heated first blank is placed in the multidirectional die forging assembly. First, start the vertical pressurizing device 1 (the position of the driving end of the vertical pressurizing device 1 before starting is the initial position), so that the driving end of the vertical pressurizing device 1 drives the upper mold 5 to move toward the die base 14, and after the upper mold 5 contacts the first blank, it continues to move in the original direction, thereby cooperating with the multi-directional die forging assembly to vertically pressurize the first blank, and then maintain the vertical pressurized state of the first blank, start the horizontal pressurizing device 89 (the position of the driving end of the horizontal pressurizing device before starting is the initial position), control the driving end of the horizontal pressurizing device 89 to drive the horizontal mold 13 through the first through hole 17 on the side wall of the die base 14, and then apply a horizontal force to the first blank. After the forging is completed, the first blank forms the required forging. At this time, the driving end of the horizontal pressurizing device 89 can be controlled to reset to the initial position first, and then the driving end of the vertical pressurizing device 1 can be controlled to reset to the initial position.
[0064] In summary, through the mutual cooperation between the vertical pressurizing device 1, the horizontal pressurizing device 89, the one-way die forging assembly 67, the multi-directional die forging assembly and the die base 14, the forging equipment can perform both ordinary die forging and multi-directional die forging, thereby realizing ordinary die forging, extrusion and multi-directional die forging forming processes on the same equipment, reducing equipment manufacturing costs, and improving equipment utilization and service life.
[0065] In some possible implementations, such as Figure 1 As shown, the one-way die forging assembly 67 includes a workbench 7 and a one-way downward die 6, wherein, when ordinary die forging is required, the workbench 7 can be detachably fixed to the top of the die base 14, and then the one-way downward die 6 is fixed to the workbench 7, and the one-way downward die 6 is located on the side of the workbench 7 away from the die base 14, so as to facilitate the one-way downward die 6 and the upper die 5 to be closed together, and the vertical load is transmitted from the one-way downward die 6 to the die base 14. Then, the heated second blank is placed on the one-way downward die 6, and the driving end of the vertical pressurizing device 1 is started to move toward the die base 14 until the upper die 5 and the one-way downward die 6 are closed together, thereby realizing vertical pressurization of the second blank. After the forging is completed, the vertical pressurizing device 1 is controlled to drive the upper die 5 to reset.
[0066] In some possible implementations, such as Figure 1As shown, an ejector device 11 is also provided on the base 12. A second through-hole 18 communicating with the inner cavity 16 can be provided at the bottom center of the die base 14. A third through-hole 19 communicating with the inner cavity 16 can be provided on the workbench 7. A fourth through-hole 20 corresponding to the third through-hole 19 is provided at the bottom of the one-way downward die 6. The second through-hole 18, the third through-hole 19, and the fourth through-hole 20 are all located in the motion path of the driving end of the ejector device 11. In this way, after the ordinary die forging is completed and the mold is closed, and the vertical pressurizing device 1 is reset, the driving end of the ejector device 11 can be controlled to pass through the second through-hole 18, the third through-hole 19, and the fourth through-hole 20 in sequence, thereby acting on the forging in the one-way downward die 6 to eject the forging and facilitate the removal of the forging. Of course, when the ejector device 11 is located at the bottom of the base 12, a through-hole can also be provided on the base 12 to facilitate the insertion of the driving end of the ejector device 11.
[0067] In some possible implementations, such as Figure 1 As shown, when the movement path of the driving end of the ejection device 11 is a vertical straight line, the through hole, the second through hole 18, the third through hole 19 and the fourth through hole 20 can all be located on the vertical straight line.
[0068] In some possible implementations, such as Figure 2 、 Figure 5 and Figure 6 As shown, the multi-directional die forging component is a multi-downward die 26, and a first through hole 27 is opened on the side wall of the multi-downward die 26. The multi-downward die 26 can be detachably installed in the inner cavity 16 of the die base 14, and the first through hole 27 is connected to the first through hole 17 in a one-to-one correspondence, which is convenient for the horizontal die 13 to pass through.
[0069] When multi-directional forging is required, such as Figure 2As shown, the unidirectional forging assembly 67 fixed to the die base 14 can be removed, and the multi-downward die 26 can be placed in the inner cavity 16 of the die base 14. Then, the heated first blank can be placed in the multi-downward die 26. First, the vertical pressure device 1 is activated (the position of the driving end of the vertical pressure device 1 before activation is the initial position), so that the driving end of the vertical pressure device 1 drives the upper die 5 toward the die base 14. After the upper die 5 and the multi-downward die 26 are closed, the closed state is maintained. At this time, the first blank is in a vertically pressurized state, and the vertical load is transmitted from the multi-downward die 26 to the die base 14. Then start the horizontal pressurizing device 89 (the position of the driving end of the horizontal pressurizing device 89 before starting is the initial position), control the driving end of the horizontal pressurizing device 89 to drive the horizontal mold 13 to pass through the first through hole 17 and the first through hole 27 in sequence, and then directly act on the first blank (when there are multiple horizontal pressurizing devices 89, this application does not limit the pressurizing sequence of the horizontal pressurizing device 89, for example, it can be simultaneous pressurization or sequential pressurization). After the forging is completed, the first blank forms the required forging. At this time, the driving end of the horizontal pressurizing device 89 can be controlled to reset to the initial position first, and then the driving end of the vertical pressurizing device 1 can be controlled to reset to the initial position.
[0070] In some possible implementations, such as Figure 2 As shown, an ejection device 11 is also provided on the base 12. A second through-hole 18 communicating with the inner cavity 16 is provided at the bottom center of the die base 14. A fifth through-hole 28 correspondingly communicating with the second through-hole 18 is provided at the bottom of the multi-downward die 26. The second through-hole 18 and the fifth through-hole 28 are both located in the motion path of the driving end of the ejection device 11. In this way, after the multi-directional die forging is completed and the vertical pressure device 1 and the horizontal pressure device 89 are reset, the driving end of the ejection device 11 can be controlled to pass through the second through-hole 18 and the fifth through-hole 28 in sequence, and then act on the forging in the multi-downward die 26 to eject the forging and facilitate the removal of the forging. Of course, when the ejection device 11 is located at the bottom of the base 12, a through-hole can also be provided on the base 12 to facilitate the insertion of the driving end of the ejection device 11.
[0071] In some possible implementations, such as Figure 2 As shown, when the movement path of the driving end of the ejection device 11 is a vertical straight line, the through hole, the second through hole 18 and the fifth through hole 28 can all be located on the vertical straight line.
[0072] It should be understood that the ejection device 11 in the ordinary die forging and the ejection device 11 in the multi-directional die forging can have the same structure, which can effectively simplify the structure.
[0073] In some possible embodiments, the single downward die 6 and the multiple downward dies 26 can be matched with the required forging lower profile. In addition, threaded holes are provided on the single downward die 6 and / or the multiple downward dies 26 to facilitate taking them out by tools such as screws.
[0074] In some possible implementations, such as Figure 1 or Figure 2 As shown, the vertical frame 23 includes a plurality of vertical columns 3 and a plurality of upper beams 2. The plurality of vertical columns 3 are parallel to each other, and one end of each vertical column 3 is fixed to the base 12, while the other end of each vertical column 3 is fixedly connected to the upper beam 2, forming a hollow frame structure. The vertical pressure device 1 is fixed to the upper beam 2. Specifically, there are four vertical columns 3. The driving end of the vertical pressure device 1 can also be slidably connected to the vertical columns 3 via a vertical slider 4, which can ensure a more stable driving end of the vertical pressure device 1 during movement.
[0075] In some possible implementations, such as Figure 1 or Figure 2 As shown, the vertical pressure device 1 is a vertical hydraulic device. The horizontal pressure device is a horizontal hydraulic device, which includes a horizontal hydraulic mechanism 8 and a fixed base 9. The housing of the horizontal hydraulic mechanism 8 is fixed to the fixed base 9, which can be fixedly connected to the mold base 14. The horizontal mold 13 can be mounted to the drive end of the horizontal hydraulic mechanism 8. Of course, in other embodiments, the vertical pressure device 1 and the horizontal pressure device can also be pneumatic devices, etc.
[0076] In some possible implementations, a positioning boss can be provided on the lower surface of the workbench 7, and a positioning hole can be provided on the top of the mold base 14. When installing the workbench 7, the positioning boss and the positioning hole can be aligned and plugged into each other to achieve rapid alignment of the workbench 7 and the mold base 14, facilitating the fixing operation between the two. Of course, in other implementations, positioning holes can also be provided on the lower surface of the workbench 7, and positioning bosses can be provided on the top of the mold base 14.
[0077] In some possible implementations, a plurality of mounting holes 24 may be provided on the top of the workbench 7 and the mold base 14 , respectively, so that the two can be fixed with screws or bolts by aligning the mounting holes 24 therebetween.
[0078] In some possible implementations, such as Figure 10 As shown, a T-shaped slot 31 can also be provided on the upper surface of the workbench 7, and the T-shaped slot 31 can be connected to the outside from the side. When installing the one-way downward mold 6, the one-way downward mold 6 can be quickly installed using T-shaped bolts.
[0079] In some possible implementations, such as Figure 1As shown, to better secure the one-way downward die 6, the one-way forging assembly 67 further includes a stopper 15. The stopper 15 is detachably fixed to the workbench 7. The stopper 15 fixed to the workbench 7 abuts against the circumference of the one-way downward die 6, thereby securing and guiding the one-way downward die 6. In addition, by adjusting the fixed position of the stopper 15 on the surface of the workbench 7, or by replacing the stopper 15 with different specifications and sizes, the workbench 7 can be made compatible with securing one-way downward dies 6 of various specifications and sizes.
[0080] In some possible implementations, such as Figures 10 to 12 As shown, the limiting block 15 and the workbench 7 that cooperate with each other are shown, wherein the upper surface of the workbench 7 is provided with fixing holes located on opposite sides, such as Figure 11 and Figure 12 As shown, the limit block 15 is long and there are two of them. Figure 1 As shown, two limit blocks 15 are fixed to the upper surface of the workbench 7 through fixing holes and fixing parts and are distributed on opposite sides of the center of the workbench 7. A one-way downward mold 6 can be installed at the center of the workbench 7, and the two limit blocks 15 are abutted against the one-way downward mold 6 on the left and right sides, thereby fixing and guiding it.
[0081] In some possible implementations, such as Figure 13 As shown, the one-way downward mold 6 can be a single station (groove-shaped), that is, the one-way downward mold 6 has a station for carrying the second blank, and the bottom of the station can be provided with a fourth through hole 20 to facilitate the driving end of the ejection device 11 to pass through. In other embodiments, such as Figure 14 and Figure 15 As shown, the one-way downward mold 6 can also have multiple stations (each of which is groove-shaped), that is, the one-way downward mold 6 has multiple stations for carrying the second blank, and a fourth through hole 20 can also be opened at the bottom of each station to facilitate the passage of the driving end of the ejection device 11.
[0082] In summary, the forging equipment of the present application is easy to implement and can be realized by adding one or two sets of horizontal loading systems to various traditional load-bearing structure types of presses such as tie rod structures, columns and tie rod structures, stacked plate structures, and steel wire prestressed winding mechanisms, with high design flexibility.

Then, the core rod in the upper die 5 continues to move vertically downward under the force of the vertical pressure device 1 (at this time, the outer main body of the upper die 5 remains stationary) at a speed of 2 mm / s, completing the extrusion forming and obtaining an intermediate forging with a cavity.
[0090] Step 4: Keep the upper die 5 and the multi-directional lower die 26 in the closed state, start the horizontal pressure device, push the horizontal die 13 to apply a horizontal load to the first blank at a speed of 4 mm / s, and complete the multi-directional die forging.
[0091] Step 5: After resetting the horizontal mold 13, reset the upper mold 5 and unload.
