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 ordinary forging and multi-directional die forging and a method for using the equipment. Background Art
[0002] Multi-directional die forging technology is an advanced forging process, which is generally carried out on a multi-directional die forging hydraulic press. Compared with traditional ordinary die forging (unidirectional die forging) and split die forging, multi-directional die forging has significant characteristics and advantages. Multi-directional die forging technology can manufacture high-quality hollow parts and complex-shaped parts with complex structures, such as hollow frames, pistons, shafts, cylindrical parts, large valve bodies and other forgings. In addition, during the die forging process, it can improve material utilization, reduce machining hours, and help improve the mechanical properties of parts.
[0003] Multi-directional die forging equipment has various forms. Since the horizontal load mechanism is added compared to the traditional press, the structure of the 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 loads and horizontal loads need to be borne by two frames that do not interfere with each other. Generally, there are two design schemes. One is that the horizontal frame surrounds the vertical frame, which has a large structure and high cost. The other is that the horizontal frame passes through the vertical frame, which will weaken the strength of the vertical frame, and 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, the vertical load and the horizontal load are borne by an integral frame at the same time. However, the integral frame has complex force, high strength requirements, and high requirements on the performance of the frame material. The processing difficulty increases accordingly, so 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 volume, high frame strength requirements and short frame life caused by unreasonable arrangement. Summary of the invention

DETAILED DESCRIPTION
[0046] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments.

[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 for protection, but merely represents selected embodiments of the present application. It should be noted that, in the absence of conflict, the various features in the embodiments of the present application can 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, further definition and explanation thereof is not required in subsequent drawings.
[0049] In the description of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the product of the application is usually placed when in use. They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.
[0050] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.
[0051] In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0052] In one aspect of the embodiments of the present application, there is provided a device suitable for ordinary 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. Please refer to Figure 1 or Figure 2 The mold base 14 is fixedly mounted on the base 12, and a plurality of horizontal pressure devices 89 are distributed around the mold base 14, such as Figure 1 or Figure 2In the figure, four horizontal pressure devices 89 are distributed one by one on the front, back, left and right sides of the die base 14. Of course, in the embodiment not shown, the horizontal pressure 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 the present application does not limit the number of horizontal pressure devices and their distribution positions on the circumference of the die base 14. For example, on a circle centered on the die base 14, several horizontal pressure 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 pressure device 89, a horizontal die 13 can be installed at the driving end of each horizontal pressure device 89, and the horizontal die 13 directly acts on the first blank, thereby forging the first blank. When the number of horizontal pressure 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 feeding, an opening 25 connected to the inner cavity 16 can be opened on the top of the mold base 14. A plurality of first through holes 17 connected to the inner cavity 16 are opened on the side wall of the mold base 14. The purpose of the plurality of first through holes 17 is to facilitate the horizontal mold 13 to pass through. Therefore, the number of first through holes 17 can be reasonably set according to the number of horizontal pressurizing devices 89. For example, a plurality of first through holes 17 corresponds to a plurality 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. 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 in the process of the horizontal pressurizing device 89 horizontally pressurizing the first blank, 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 bulky 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 implementations, 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, such as Figure 1 or Figure 2 In the embodiment, two horizontal pressurizing devices 89 distributed on the front and rear sides of the mold base 14 form a group, and 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 may be provided on the side wall of the die base 14, and the horizontal pressure device 89 may be fixedly connected to the boss 22, thereby realizing a fixed connection between the horizontal pressure device 89 and the die base 14. When the connection is made, it may be fixed by welding or the like, or it may be connected by bolts, for example 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 may 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 U-shaped ... Figure 3 In the figure, the mold base 14 is generally in the shape of a Chinese umbilical cord when viewed from above.
[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. In addition, a T-shaped slot may be provided on the die base mounting plate 10, and a mounting hole is provided at a corresponding position at the bottom of the die base 14. The mounting hole and the T-shaped slot may be connected by a T-shaped bolt to achieve the fixation of the die base 14 and the die base mounting plate 10. In order to facilitate the insertion of the driving end of the ejection device 11, a perforation is provided at the center of the die base mounting plate 10, so that the driving end of the ejection device 11 can be inserted in the 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 die base 14. In other words, when the driving end of the vertical pressurizing device 1 telescopically moves in the vertical direction, the die 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 die base 14 when moving in the vertical direction, so as to vertically pressurize the first blank or the second blank on the die base 14.
[0060] In order to obtain the required forgings, an upper die 5 may be installed on the driving end of the vertical pressurizing 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 unidirectional die forging assembly 67 and a multidirectional die forging assembly that can be replaced on the die base 14, so that 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, and then the second blank in the unidirectional die forging assembly 67 can be vertically pressurized by the vertical pressurizing device 1 in cooperation with the die base 14, so as to obtain the desired forging; and 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 is installed on the die base 14, and then the first blank in the multidirectional die forging assembly is vertically pressurized by the vertical pressurizing device 1 in cooperation with the die base 14, and then the first blank in the vertical pressurized state is horizontally pressurized by the aforementioned horizontal pressurizing device 89, 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 component 67 is fixedly provided on the die base 14, and then the heated second blank is placed in the one-way die forging component 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 component 67 to vertically pressurize the second blank. After the forging is completed, the second blank forms the desired 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 component 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 pressurization 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), and 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, thereby applying a horizontal force to the first blank. After the forging is completed, the first blank forms the desired 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 unidirectional 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 the equipment manufacturing cost and improving the equipment utilization rate 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 molded 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 molded 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 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, and a fourth through hole 20 correspondingly communicating with 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 movement path of the driving end of the ejector 11, so that after the ordinary die forging is completed and the vertical pressurizing device 1 is reset, the driving end of the ejector 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, and then act on the forging in the one-way downward die 6 to realize the ejection of the forging and facilitate the removal of the forging. Of course, when the ejector 11 is located at the bottom of the base 12, a through hole can also be provided on the base 12 to facilitate the penetration of the driving end of the ejector 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 is detachably installed in the inner cavity 16 of the die base 14, and the first through hole 27 is connected with the first through hole 17 in a one-to-one correspondence, so as to facilitate the installation of the horizontal die 13.
[0069] When multi-directional forging is required, such as Figure 2As shown, the one-way die forging assembly 67 fixed on the die base 14 can be removed, and the multi-downward die 26 is placed in the inner cavity 16 of the die base 14, and then the heated first blank is placed in the multi-downward die 26. First, 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 and the multi-downward die 26 are closed, the closed state is maintained. At this time, the first blank is in a vertical 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, the present 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 corresponding to and communicating with the second through hole 18 is provided at the bottom of the multi-downward die 26, and the second through hole 18 and the fifth through hole 28 are both located in the movement 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 realize the ejection of 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 penetration 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 ejector device 11 in the common die forging and the ejector device 11 in the multi-directional die forging can be of 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 match 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, wherein the plurality of vertical columns 3 are parallel to each other, and one end of the vertical column 3 is fixed to the base 12, and the other end of the vertical column 3 is fixedly connected to the upper beam 2, forming a hollow frame structure, and the vertical pressure device 1 is fixed to the upper beam 2. Specifically, the number of vertical columns 3 is four. The driving end of the vertical pressure device 1 can also be slidably connected to the vertical column 3 via a vertical slider 4, so that the driving end of the vertical pressure device 1 can be more stable during movement.
[0075] In some possible implementations, such as Figure 1 or Figure 2 As shown, the vertical pressurizing device 1 is a vertical hydraulic device. The horizontal pressurizing device is a horizontal hydraulic device, which includes a horizontal hydraulic mechanism 8 and a fixing seat 9. The housing of the horizontal hydraulic mechanism 8 is fixed to the fixing seat 9. The fixing seat 9 can be fixedly connected to the mold base 14. The horizontal mold 13 can be installed on the driving end of the horizontal hydraulic mechanism 8. Of course, in other embodiments, the vertical pressurizing device 1 and the horizontal pressurizing device can also be pneumatic devices, etc.
[0076] In some possible implementations, a positioning boss may be provided on the lower surface of the workbench 7, and a positioning hole may be provided on the top of the mold base 14. When the workbench 7 is installed, the positioning boss and the positioning hole may be aligned and plugged 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, a positioning hole may be provided on the lower surface of the workbench 7, and a positioning boss may be provided on the top of the mold base 14.
[0077] In some possible implementations, a plurality of mounting holes 24 may be respectively provided on the top of the workbench 7 and the mold base 14, and the two may be fixed by means of screws or bolts through the alignment of the mounting holes 24 between the two.
[0078] In some possible implementations, such as Fig.10 As shown, a T-shaped slot 31 may be provided on the upper surface of the workbench 7, and the T-shaped slot 31 may be connected to the outside from the side, and when the one-way downward mold 6 is installed, the one-way downward mold 6 may be quickly installed using a T-shaped bolt.
[0079] In some possible implementations, such as Figure 1As shown, in order to better fix the one-way downward die 6, the one-way die forging assembly 67 also includes a stopper 15, which is detachably fixed to the workbench 7. The stopper 15 fixed to the workbench 7 just abuts against the peripheral side of the one-way downward die 6, thereby fixing 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 of different specifications and sizes, the workbench 7 can be compatible with fixing one-way downward dies 6 of various specifications and sizes.
[0080] In some possible implementations, such as Figures 10 to 12 As shown, the stopper 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 Fig.11 and Fig.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. The 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 to fix and guide it.
[0081] In some possible implementations, such as Fig.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 Fig.14 and Fig.15 As shown, the single-downward mold 6 can also have multiple stations (each of which is groove-shaped), that is, the single-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 penetration 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 prestressed wire winding mechanisms, with high design flexibility.
