[0044] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention.

[0045] It should be noted that the illustrations provided in this embodiment are only used to schematically illustrate the basic concept of the present invention. Therefore, the illustrations only show components related to the present invention and are not drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0046] In the connection structure between the anvil or forging tool and the anvil, a dovetail key structure is often used for assembly connection. The key penetrates the connected anvil or forging tool and anvil in the width direction, thereby ensuring a reliable connection and facilitating disassembly. However, this structure cannot be used for installation of wider anvils or hollow forging tooling that does not allow penetration.

[0047] See also Figures 1 to 12The present invention provides a connection device for a forging tool 500, which includes a buckle 100, a wedge 200, and a fixing member 300. The buckle 100 gradually decreases in width in a first direction, and first decreases and then increases in width in a second direction. A first connection hole is provided along a third direction. The first, second, and third directions are mutually perpendicular and correspond to the positive directions of the X-axis, Y-axis, and Z-axis, respectively. The wedge 200 is distributed between the two buckles 100 along the third direction and is connected thereto. The width gradually increases in the first direction, and a second connection hole is provided along the third direction. The two buckles 100 are symmetrically distributed about the wedge 200, facilitating processing and installation. The fixing member 300 connects and fixes the buckle 100 to the wedge 200 through the first and second connection holes.

[0048] See also Figures 1 to 12 It should be noted that the forging tool 500 connection device can be applied to the connection between the forging tool 500 and the anvil 400. Here, the forging tool 500 includes various anvils and other forging tools 500, especially, for example, wider anvils and various hollow forging tools 500. It is only necessary to open a dovetail groove of corresponding shape on the side of the forging tool 500 and the anvil 400, put the large end of the buckle 100 and the wedge 200 into the dovetail groove along the first direction and fix it with the fixing piece 300. The connection can be achieved; since the connecting device gradually decreases in size from the inside to the outside along the anvil 400 and the forging tool 500, and gradually increases in size on both sides along the connecting surface of the anvil 400 and the forging tool 500, the buckle 100 and the wedge 200 are tightly fixed and engaged in the dovetail groove, and its overall structure ensures that the anvil 400 and the forging tool 500 will not produce relative displacement in any direction under the action of the connecting device, thereby ensuring a tight and reliable connection; at the same time, the various components of the connecting device are connected by snap-fitting and are easy to disassemble.

[0049] See also Figures 2 to 6 According to an embodiment provided by the present invention, the two end faces of the buckle 100 in the first direction are the first inner end face 120 and the first outer end face 130 respectively, and the two end faces in the second direction are the first lower end face 150 and the first upper end face 140 respectively. The first inner end face 120 is parallel to the first outer end face 130, and the first upper end face 140 is parallel to the first lower end face 150. When connecting, each end face abuts against the corresponding faces in the cavity formed by the anvil 400 and the forging tool 500 to ensure a tight connection.

[0050] See also Figures 2 to 6According to an embodiment of the present invention, the side of the buckle 100 close to the wedge 200 in the third direction is the first connecting surface 110, and the angle between the first connecting surface 110 and the first inner end surface 120 is 80 degrees. When the wedge 200 is located between the two buckles 100 and connected to the first connecting surfaces 110 of the two buckles 100, it is convenient for the wedge 200 to be inserted between the two buckles 100 and squeezed tightly to achieve a tight and reliable overall connection. At the same time, when disassembling the connecting device, the inclined surfaces on both sides are used to apply oblique pressure to the wedge 200, making it easier for the wedge 200 to detach from the buckle 100, and the disassembly process is easy and convenient.

[0051] See also Figures 2 to 6 According to one embodiment of the present invention, the side of the buckle 100 facing away from the wedge 200 in the third direction includes a second connecting surface 160 and a third connecting surface 170. The second connecting surface 160 and the third connecting surface 170 form an angle of 87° with the first inner end surface 120. The wedge 200 is clamped between the two buckles 100 and connected as a whole, fitting within the cavity formed by the anvil 400 and the forging tool 500. The second connecting surface 160 and the third connecting surface 170 respectively fit tightly against the side surfaces of the inner cavity of the forging tool 500 and the anvil 400, ensuring that the anvil 400 and the forging tool 500 do not move relative to each other in the third direction. Furthermore, because the connecting device is larger inside the cavity and smaller outside, and the first inner end surface 120 abuts against the inner end surface of the cavity, when the buckle 100 and the wedge 200 are fixed, the anvil 400 and the forging tool 500 do not move relative to each other in the first direction.

[0052] See also Figures 2 to 6 According to one embodiment of the present invention, the buckle 100 has a vertically symmetrical structure, with the second and third connecting surfaces 160, 170 forming an angle of 83° with the first upper end surface 140. The second and third connecting surfaces 160, 170 of the two buckles 100 are arranged in a V-shaped structure on either side of the connecting surface between the forging tool 500 and the anvil 400. Because the dimensions of the connecting device on both sides of the connecting surface are larger than the dimensions at the connecting surface, the anvil 400 and the forging tool 500 can be pressed toward the connecting surface without causing relative movement in the second direction. Furthermore, when the connecting device is disassembled, when the forging tool 500 is lifted, the buckle 100 is subjected to an oblique force at the two connecting surfaces, causing it to move toward the center, thereby squeezing the wedge 200 and causing it to fall off, thus completing disassembly and operating conveniently. Of course, in other embodiments, the buckle 100 may also be an asymmetric structure. In this case, the corresponding dovetail groove shapes on the forging tool 500 and the anvil 400 are also different, and the two dovetail groove structures respectively match the second connecting surface 160 and the third connecting surface 170.

[0053] See also Figures 2 to 9According to an embodiment provided by the present invention, the two end surfaces of the wedge 200 in the third direction are respectively a first side surface 210 and a second side surface 220. The first side surface 210 and the second side surface 220 are respectively cooperated and connected with the first connecting surfaces 110 of the two buckles 100. Specifically, the first side surface 210 and the second side surface 220 abut against the two first connecting surfaces 110 and are interference-connected therewith, ensuring that the overall engagement of the connecting device is tight and reliable.

[0054] See also Figures 2 to 9 According to an embodiment provided by the present invention, the two end faces of the wedge 200 in the first direction are the second inner end face 230 and the second outer end face 240 respectively, and the two end faces in the second direction are the second lower end face 260 and the second upper end face 250 respectively, the second inner end face 230 is parallel to the second outer end face 240, and the second upper end face 250 is parallel to the second lower end face 260; when the wedge 200 is engaged between the two buckles 100, the first upper end face 140 and the second upper end face 250 are located in the same plane, and the first lower end face 150 and the second lower end face 260 are located in the same plane, and the end faces of the wedge 200 and the buckle 100 respectively abut against the respective faces of the cavity structure formed by the anvil 400 and the forging tool 500, ensuring that the connection is tight and reliable and supported in the cavity to ensure the strength of the anvil 400 and the forging tool 500.

[0055] See also Figures 2 to 9 According to an embodiment of the present invention, the angles between the first side surface 210 and the second side surface 220 of the wedge 200 and the second outer end surface 240 are both 80°, and its horizontal cross-section is an isosceles trapezoid. Both sides are inclined surfaces with the first connecting surface 110 of the buckle 100 and are connected to each other. When installing the connecting device, the structure with a larger outside and a smaller inside makes it easy to insert the wedge 200 along the first connecting surface 110 between the bayonet holes and squeeze it tightly to ensure a reliable connection. When disassembling, this structure is used to make the wedge 200 easy to come out under the oblique force of the buckles 100 on both sides, thereby facilitating installation and disassembly and reducing operating intensity.

[0056] See also Figures 1 to 9 According to an embodiment provided by the present invention, the first connecting hole and the second connecting hole are respectively arranged on one side close to the first outer end surface 130 and the second outer end surface 240, and penetrate the buckle 100 and the wedge 200 along the third direction. The size of the first connecting hole from the first upper end surface 140 is equal to the size of the second connecting hole from the second upper end surface 250, and the size of the first connecting hole from the first outer end surface 130 is equal to the size of the second connecting hole from the second outer end surface 240. When the wedge 200 is engaged between the two buckles 100, the first connecting hole and the second connecting hole are positioned in the same manner, and the fixing member 300 passes through the first connecting hole and the second connecting hole to connect and fix the two buckles 100 and the wedge 200.

[0057] Understandably, see Figures 1 to 9 When installing the connecting device, part of the buckle 100 and the wedge 200 are located in the cavity formed between the forging tool 500 and the anvil 400, and part of them are located outside the cavity and are provided with a first connecting hole and a second connecting hole. The fixing member 300 passes through the first connecting hole and the second connecting hole to fix the buckle 100 and the wedge 200 to ensure the stable connection of the entire connecting device. The connecting hole is, for example, a pin hole, and the fixing member 300 corresponds to a plug. During installation, you only need to insert the plug into the hole to effectively limit the buckle 100 and the wedge 200 to ensure the stability of the connection. When disassembling, you only need to pull out the pin. The structure is simple and the operation is convenient.

[0058] See also Figures 1 to 12 The present invention also proposes a forging tool 500 connection structure, including an anvil 400, a forging tool 500 and a connecting device. A first dovetail groove 410 is provided on the anvil 400, and the openings of the first dovetail groove 410 are respectively located on the upper end face of the anvil 400 and its adjacent face, and the width of the first dovetail groove 410 gradually decreases in the first direction and the second direction, wherein the first direction is perpendicular to the second direction, and the second direction is perpendicular to the upper end face of the anvil 400, and the first direction and the second direction correspond to the positive direction of the X axis and the positive direction of the Y axis respectively; the forging tool 500 is connected to the anvil 400, and a second dovetail groove 510 is provided on it, and the openings of the second dovetail groove 510 are respectively located on the forging tool The lower end face of the anvil 400 and its adjacent face of the forging tool 500, and the width of the second dovetail groove 510 gradually decreases in the first direction and gradually increases in the second direction; the upper end face of the anvil 400 is connected to the lower end face of the forging tool 500 to form a connecting surface, the first dovetail groove 410 and the second dovetail groove 510 are symmetrically distributed about the connecting surface, and the first dovetail groove 410 and the second dovetail groove 510 together form a connecting groove; the structure of the connecting device is consistent with the structure of the connecting groove, and the connecting device is partially engaged in the connecting groove and fixed to connect the anvil 400 and the forging tool 500.

[0059] Specifically, the connecting device includes a buckle 100, a wedge 200 and a fixing member 300, and its overall structure matches the connecting groove structure. The buckles 100 are symmetrically distributed on both sides of the connecting groove and are connected with each plane of the connecting groove. The width of the buckle 100 gradually decreases in the first direction, and the width first gradually decreases and then gradually increases in the second direction; the wedge 200 is arranged between the two buckles 100, cooperates with and connects with and presses the buckle 100, and is jointly engaged in the connecting groove, and the width of the wedge 200 gradually increases in the first direction; the parts of the buckle 100 and the wedge 200 located outside the connecting groove are provided with connecting holes along the third direction, and the fixing member 300 connects and fixes the wedge 200 and the buckle 100 through the connecting holes to ensure that the wedge 200 and the buckle 100 do not slide relative to each other in the connecting groove, wherein the third direction is perpendicular to the first direction and the second direction, corresponding to the positive direction of the Z axis.

[0060] See also Figures 1 to 12 When using the forging tool 500 connecting device of the utility model to connect the forging tool 500 and the anvil 400, first align the dovetail grooves of the forging tool 500 and the anvil 400 to form a connecting groove, and place the two clips 100 on both sides of the connecting groove and fit with their side surfaces, insert the wedge 200 between the two clips 100, squeeze them tightly, so that the pin holes of the three are aligned, and insert the pin into the pin holes of the clip 100 and the wedge 200 to prevent them from sliding relative to each other; at this time, since the size of the combination of the clip 100 and the wedge 200 gradually decreases along the inside of the connecting groove to the outside end face, the size along the inside of the forging tool 500 and the anvil 400 to their connecting surface also gradually decreases, and the shape of the connecting device fits the shape of the inside of the connecting groove and is tightly connected, ensuring that the combination will not fall off from the connecting groove, thereby achieving complete limitation of the anvil 400 and the forging tool 500 and ensuring that the overall connection is tight and reliable. Since the connecting device is arranged on the side of the anvil 400 and the forging tool 500, in order to achieve a reliable connection between the forging tool 500 and the anvil 400, at least 4 groups of the device are usually required to be connected at the same time. It can be understood that the number and distribution of the connecting devices can be set differently according to actual needs, so that it can adapt to various complex working environments, be flexible in use, and have strong adaptability.

[0061] See also Figures 1 to 12 When disassembly is required, first pull out the pin and then lift the forging tool 500. At this time, due to the effects of gravity and tension, the buckles 100 are squeezed at the two connecting surfaces and subjected to an oblique force. The two buckles 100 tend to move toward the middle. The wedge 200 is squeezed out under the pressure of the two buckles 100, and the connecting device is loosened, so that the forging tool 500 can be separated from the anvil 400.

[0062] The forging tool 500 connecting device and the forging tool 500 connecting structure of the present invention are as follows: in the connecting device, a combination of two clips 100 symmetrically arranged about the wedge 200 is placed in the connecting groove formed by the dovetail groove on the anvil 400 and the forging tool 500, and the shape of the combination is consistent with the connecting groove structure. The second connecting surface 160 and the third connecting surface 170 of the clip 100 are used to limit the anvil 400 and the anvil block in the first direction and the second direction, and the first connecting surface 110 of the clip 100 and the two side surfaces of the wedge 200 limit the anvil 400 and the anvil block in the third direction, and the latch connects the clip 100 with After the wedge 200 is fixed, a tight and reliable connection can be achieved between the anvil 400 and the forging tool 500, and the strength of the forging tool 500 is guaranteed; its structure is simple, making the installation and disassembly process simple and convenient, with low operating intensity, and easy to manufacture, reducing production costs; the connecting device and the connecting groove are arranged on the side of the anvil 400 and the forging tool 500, which can be suitable for the connection of a wider anvil block or a hollow forging tool 500 that is not allowed to pass through and the anvil 400. It has a reasonable design and can flexibly adjust the setting of the connecting device to adapt to various complex working environments. It has strong adaptability and a wide range of application scenarios.
