[0029] like Figures 1 to 11 As shown, the first embodiment of the present invention provides a forging machine that allows no typical parting surface, including: Rack 100; The upper mold core 102 is movably mounted on the frame 100, and the upper mold core 102 is suitable for moving relative to the frame 100 along the height direction of the frame 100; The side mold body is arranged below the upper mold core 102; A first driving device is installed on the frame 100 and is in driving connection with the side mold body to drive the side mold body to switch between a closed state and a separated state; In the closed state, the upper mold core 102 is suitable for surrounding with the side mold body to form a mold cavity to forge the blank. In the separated state, the upper mold core 102 is suitable for moving away from the side mold body to avoid the mold cavity.

[0030] According to the forging machine that allows the absence of a typical parting surface, a first driving device is provided on the frame 100, and the first driving device drives the side die body to switch between a closed state and a separated state. When the first driving device drives the side die body to be in a closed state, the upper die core 102 can be pressed down and surrounded by the side die body to form a die cavity to forge the blank and maintain pressure. When the first driving device drives the side die body to be in a separated state, the upper die core 102 can be away from the side die body to avoid the die cavity. At this time, the forged blank can be taken out, thereby allowing high-precision near-net forming and smooth demolding of complex parts without a typical parting surface, thereby improving the utilization rate of raw materials. The forging machine has a simple structure and high forging efficiency.

[0031] Please continue to see Figures 1 to 11 In the embodiment of the present invention, the frame 100 uses a forging blank to reduce the deformation of the frame 100 when it is subjected to a huge load. The frame 100 is configured as a prestressed winding frame 100, which is composed of a left column, an upper semicircular beam, a right column and a lower semicircular beam connected in sequence, and then a high-strength steel wire is pre-tightened and wound around the outer sides of the left column, the upper semicircular beam, the right column and the lower semicircular beam to form a whole.

[0032] An upper mold core 102 is arranged above the frame 100, and the upper mold core 102 can move relative to the frame 100 along the height direction of the frame 100; a second driving device is arranged on the frame 100, and the second driving device is transmission-connected with the movable beam 114; the movable beam 114 and the frame 100 are suitable for being guided and connected with each other through a second guide structure, so that the movable beam 114 moves along the axial direction of the upper mold core 102; and / or, a detection component is arranged on the movable beam 114, and the detection component is suitable for detecting the relative position of the movable beam 114 and the frame 100.

[0033] According to one embodiment of the present invention, a movable beam 114 is disposed on the frame 100 , and the movable beam 114 is transmission-connected to the upper mold core 102 to drive the upper mold core 102 to move along the height direction of the frame 100 .

[0034] like Figures 1 to 4 As shown, in the embodiment of the present invention, a movable beam 114 is disposed on the frame 100 , and the movable beam 114 can move relative to the frame 100 along the height direction of the frame 100 .

[0035] The second driving device can be a hydraulic cylinder, etc. Taking the hydraulic cylinder as an example, the piston rod of the hydraulic cylinder is fixedly connected to the lower surface of the upper semicircular beam, and the cylinder barrel of the hydraulic cylinder is integrated with the movable beam 114 to increase the rigidity of the movable beam 114.

[0036] The columns of the rack 100 are of square cross-section, such as Figure 2 As shown, each column is provided with a plane guide plate on the edge, a support block is provided at the head and tail of the hydraulic cylinder, and a guide pad is provided at each of the four corners of each support block. The guide pad and the plane guide plate are mutually sliding pairs. Therefore, the forging machine provided by the present invention has a longer guide spacing. When a balancing cylinder is not provided, the frame 100 can withstand a larger offset. Figure 2 As shown, the column is provided with a longitudinal standard line, and a plurality of distance measuring sensors are provided on the side of the movable beam 114 to measure the horizontal deviation of the movable beam 114 during the upward and downward movement, including but not limited to laser sensors, eddy current sensors, etc. The longitudinal standard line of the column and the distance measuring sensors provided on the movable beam 114 constitute the detection device of the movable beam 114. The above design scheme controls the guiding accuracy of the movable beam 114 within ±0.1 mm, thereby ensuring the high-precision forging of complex parts.

[0037] The side mold body is arranged below the movable beam 114, and the side mold body can be switched between a closed state and a separated state under the driving action of the first driving device. In the closed state, the upper mold core 102 is suitable for forming a mold cavity with the side mold body to forge the blank, and in the separated state, the upper mold core 102 is suitable for moving away from the side mold body to avoid the mold cavity.

[0038] like Figures 1 to 3 As shown, when the side mold body is in a closed state, the upper mold core 102 is pressed downward and surrounded by the side mold body to form a mold cavity for forging the blank. When the side mold body is in a separated state, the upper mold core 102 moves upward to move away from the side mold body. At this time, the mold cavity is avoided and the forged blank can be taken out.

[0039] According to one embodiment of the present invention, the first driving device comprises: A driving member 104 is mounted on the frame 100; A transmission member 106, two ends of which are respectively hinged to the driving member 104 and the side mold body; The driving member 104 is suitable for switching between a first position and a second position. From the first position to the second position, the driving member 104 is suitable for driving the transmission member 106 to switch the side mold body to a closed state; from the second position to the first position, the driving member 104 is suitable for driving the transmission member 106 to switch the side mold body to a separated state.

[0040] In the embodiment of the present invention, the driving member 104 is installed on the frame 100, that is, the installation position of the driving member 104 corresponds to the position of the side mold body.

[0041] A transmission member 106 is connected between the driving member 104 and the side mold body, and the two ends of the transmission member 106 are respectively hinged to the driving member 104 and the side mold body. Figure 1 , Figure 3 and Figure 4 As shown, in the embodiment of the present invention, when the frame 100 is in a vertical state, the axes of the hinge shafts of the transmission member 106, the driving member 104, and the side mold body can be parallel to the horizontal plane and perpendicular to the axis of the upper mold core 102; or Figure 7 As shown, when the frame 100 is in a vertical state, the axes of the transmission member 106 , the driving member 104 , and the hinge shaft of the side mold body can be perpendicular to the horizontal plane and parallel to the axis of the upper mold core 102 .

[0042] In the embodiment of the present invention, the two ends of the transmission member 106 are respectively hinged to the driving member 104 and the side mold body, which means that the transmission member 106 can rotate relative to the driving member 104 and the side mold body.

[0043] The driving member 104 can switch between the first position and the second position. When the driving member 104 switches from the first position to the second position, the driving member 104 can drive the transmission member 106 to move. After being driven by the transmission member 106, the transmission member 106 can synchronously drive the side mold body to switch from the separated state to the closed state. When the driving member 104 switches from the second position to the first position, the driving member 104 can drive the transmission member 106 to move. After being driven by the transmission member 106, the transmission member 106 can synchronously drive the side mold body to switch from the closed state to the separated state. That is, as the driving member 104 moves between the first position and the second position, the side mold body can be driven by the transmission member 106 to switch between the closed state and the separated state. When the side mold body is in the closed state, the blank on the side mold body can be forged through the upper mold core 102. When the side mold body is in the separated state, the blank on the side mold body can be taken out.

[0044] According to one embodiment of the present invention, it also includes a lower pad 108, which is arranged below the side mold body. The lower pad 108 and the side mold body are suitable for being connected through a first guide structure to enable the side mold body to move in the radial direction of the axis of the upper mold core 102.

[0045] like Figures 5 to 7 As shown, in the embodiment of the present invention, a lower pad 108 is further provided on the lower semicircular beam, and the lower pad 108 is located below the side mold body. The purpose of providing the lower pad 108 is to provide guidance for the movement of the side mold body. It can be understood that in order to achieve the guidance of the side mold body, the side mold body and the lower pad 108 are connected by a first guide structure.

[0046] In one embodiment, the first guide structure can be a guide block provided on the lower pad 108 and a guide groove provided below the side mold body. The guide block extends along the radial direction of the upper mold core 102. During the movement of the side mold body, the side mold body can be guided by the cooperation of the guide groove and the guide block, so that the side mold body can move along the radial direction of the upper mold core 102.

[0047] In some other embodiments, the first guide structure may also be a T-shaped block disposed below the side mold body and a T-shaped slot disposed on the lower pad 108. The T-shaped slot extends along the radial direction of the upper mold core 102. The cooperation of the T-shaped block and the T-shaped slot can not only guide the side mold body, but also prevent the side mold body from being separated from the lower pad 108.

[0048] It can be seen from the above description that in the embodiment of the present invention, when the side mold body switches between the closed state and the separated state, the side mold body moves radially along the axis direction of the upper mold core 102. That is, when the frame 100 is in a vertical state, the movement direction of the side mold body is in a horizontal plane.

[0049] According to one embodiment of the present invention, a connecting ring 110 is further included, and the driving member 104 is connected to the connecting ring 110; The side mold body includes a plurality of side mold segments 112, and the transmission member 106 is arranged one-to-one corresponding to the plurality of side mold segments 112 and is respectively connected between the connecting ring 110 and the plurality of side mold segments 112; In the closed state, the plurality of side mold segments 112 are closed to form a side mold main body, and in the separated state, the side mold main body is separated to form a plurality of side mold segments 112 .

[0050] See also Figures 5 to 11 In an embodiment of the present invention, the forging machine that allows for no typical parting surface also includes a connecting ring 110, which is sleeved on the periphery of the side die body and connected to the side die body through a transmission member 106.

[0051] The side mold body includes a plurality of side mold segments 112. It is understandable that the plurality of side mold segments 112 can be spliced ​​together to form the side mold body. At this time, the side mold body formed by splicing the plurality of side mold segments 112 is in a closed state; when the side mold body is in a separated state, the side mold body can be separated to form a plurality of side mold segments 112. For example, if there are eight side mold segments 112, the eight side mold segments 112 can be spliced ​​together to form the side mold body, and when the side mold body is separated, it can be decomposed to form eight side mold segments 112.

[0052] According to one embodiment of the present invention, the driving member 104 includes a hydraulic member, the axis of the output shaft of the hydraulic member is parallel to the axis of the upper mold core 102, the output end of the hydraulic member is hinged to the transmission member 106, and the output end of the hydraulic member is suitable for switching between the first position and the second position; From the second position to the first position, the output end of the hydraulic component is suitable for driving the connecting ring 110 to move in the direction close to the upper mold core 102, so as to drive the multiple side mold splits 112 to close through the transmission member 106. From the first position to the second position, the output end of the hydraulic component is suitable for driving the connecting ring 110 to move in the direction away from the upper mold core 102, so as to drive the multiple side mold splits 112 to separate through the transmission member 106.

[0053] In this embodiment, the driving member 104 is a hydraulic member, and accordingly, two blind holes can be set at the same diameter direction of the lower semicircular beam, the cylinder of the hydraulic member is set in the blind holes, and the output shaft of the hydraulic member is connected to the connecting ring 110. At this time, the output shaft of the hydraulic member can move along the height direction of the frame 100, that is, the output shaft of the hydraulic member can move along the direction parallel to the axial direction of the upper mold core 102 to drive the connecting ring 110 to move synchronously.

[0054] Specifically, the output end of the hydraulic component can be switched between a first position and a second position, wherein the first position mentioned here refers to a position where the output end of the hydraulic component is extended, and the second position mentioned here refers to a position where the output end of the hydraulic component is retracted.

[0055] When the output end of the hydraulic component switches from the retracted position to the extended position, the output end of the hydraulic component can drive the connecting ring 110 to move upward. During the upward movement of the connecting ring 110, the connecting ring 110 drives the transmission member 106 to rotate. Since the side mold split 112 can only move radially along the axial direction of the upper mold core 102, the transmission member 106 will push the side mold split 112 to approach each other. When the transmission member 106 is in a horizontal position, the output end of the hydraulic component reaches the highest point of the retracted position, and dead points appear between the output end of the hydraulic component and the connecting ring 110, and between the connecting ring 110 and the transmission member 106. That is, at this time, the hydraulic pressure applied by the output end of the hydraulic component to the connecting ring 110 and the pre-tightening force applied by the connecting ring 110 to the transmission member 106 can form a self-locking for the side mold split 112. When the upper mold core 102 moves downward to forge the blank, it can ensure that the side mold body has sufficient bearing capacity.

[0056] When the output end of the hydraulic component switches from the extended position to the retracted position, the output end of the hydraulic component can drive the connecting ring 110 to move downward. During the downward movement of the connecting ring 110, the connecting ring 110 drives the transmission member 106 to rotate. Since the side mold split 112 can only move radially along the axis direction of the upper mold core 102, the transmission member 106 drives the side mold split 112 to move away from each other. When the output end of the hydraulic component reaches the lowest point of the retracted position, the side mold body reaches a separated state. At this time, the blank on the side mold body can be taken out.

[0057] According to one embodiment of the present invention, the driving member 104 comprises a rotary motor, and an output end of the rotary motor is adapted to switch between a first position and a second position; From the second position to the first position, the connecting ring 110 is suitable for driving the connecting ring 110 or the lower pad 108 to rotate forward to separate the multiple side mold splits 112, and from the first position to the second position, the connecting ring 110 is suitable for driving the connecting ring 110 or the lower pad 108 to rotate backward to close the multiple side mold splits 112.

[0058] In this embodiment, the driving member 104 may be a rotary motor, and accordingly, the rotary motor may be installed on the lower semicircular beam. The output end of the rotary motor is connected to the connecting ring 110 or the lower pad 108 to drive the multiple side mold bodies to move closer to or farther from each other through the transmission member 106.

[0059] Specifically, taking the connection between the output end of the rotating motor and the connecting ring 110 as an example, when the output end of the rotating motor switches from the first position to the second position, the rotating motor can drive the connecting ring 110 to rotate in the opposite direction. During the reverse rotation of the connecting ring 110, since the side mold split 112 can only move radially along the axial direction of the upper mold core 102, the transmission member 106 will drive the side mold split 112 to approach each other and reach a closed state.

[0060] When the output end of the rotating motor switches from the second position to the first position, the rotating motor can drive the connecting ring 110 to rotate in the forward direction. During the forward rotation of the connecting ring 110, since the side mold split 112 can only move radially along the axial direction of the upper mold core 102, the transmission member 106 will drive the side mold split 112 to move away from each other and reach a separated state.

[0061] Taking the connection between the output end of the rotating motor and the lower pad 108 as an example, when the output end of the rotating motor switches from the first position to the second position, the rotating motor can drive the lower pad 108 to rotate in the opposite direction. During the reverse rotation of the lower pad 108, since the side mold split 112 can only move radially along the axial direction of the upper mold core 102, the transmission member 106 will drive the side mold split 112 to approach each other and reach a closed state.

[0062] When the output end of the rotating motor switches from the second position to the first position, the rotating motor can drive the lower pad 108 to rotate forward. During the forward rotation of the lower pad 108, since the side mold split 112 can only move radially along the axial direction of the upper mold core 102, the transmission member 106 will drive the side mold split 112 to move away from each other and reach a separated state.

[0063] According to one embodiment of the present invention, an ejection mechanism 116 is disposed below the side mold body. In the separated state, the ejection mechanism 116 is adapted to move relative to the mold cavity to eject the blank.

[0064] See also Figures 5 to 7 In the embodiment of the present invention, in order to facilitate the removal of the forged blank, an ejection mechanism 116 is further provided on the lower pad 108. The ejection mechanism 116 may be a hydraulic rod provided at the center of the lower semicircular beam. When the forging of the blank is completed, the hydraulic rod extends to eject the blank on the side die body.

[0065] like Fig.12 As shown, the second aspect of the present invention provides a method for using the forging machine as described above that allows for no typical parting surface, comprising: Step 10, driving the side mold body from the separated state to the closed state through the first driving device; Step 20, placing the blank in the mold cavity; Step 30, driving the upper die core 102 to forge the blank and maintain the pressure; Step 40, driving the upper mold core 102 to move in a direction away from the blank; Step 50, driving the side mold body from the closed state to the separated state through the first driving device, and taking out the blank.

[0066] According to the method for using a forging press that allows for no typical parting surface provided in an embodiment of the second aspect of the present invention, by being implemented based on the above-mentioned forging press that allows for no typical parting surface, it is possible to improve the high-precision forging and forming of complex parts without typical parting surfaces, and can ensure that the complex parts can be smoothly demolded after the forging is completed, thereby achieving high-precision and rapid forging of complex parts without typical parting surfaces.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
