Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of forging machines, in particular to a forging machine for magnesium alloy forgings. BACKGROUND

[0002] The forging machine is a device specially used for forging treatment of metals or alloys. When the metals or alloys are subjected to forging treatment, plastic deformation occurs, because the original coarse grains are broken and rearranged to form fine and uniform equiaxed grains through plastic deformation at high temperature, thereby greatly improving the mechanical properties of the metals or alloys.

[0003] In metal forging, in order to ensure the accuracy of hammering, a clamp is generally used to fix the position of the metal. However, at the moment when the metal is subjected to hammering, the plastic deformation of the metal and the vibration of the support seat will affect the clamping effect of the clamp, causing the clamp to slide, which reduces the forging accuracy. The existing forging machine can only increase the clamping force of the clamp to ensure the stability of the metal during forging. For example, the forging machine disclosed in Chinese Patent No. CN118341930A cannot absorb the plastic flow deformation of the metal and the vibration of the support seat at the moment when the metal is subjected to hammering, which causes the metal to be easily clamped and slide, resulting in inaccurate forging.

process of the forging machine through the control cabinet 5, and the clamping mechanism 8 is arranged on the forging base 7, which is used for clamping the forging piece, and it should be noted that,

arranged on the forging base 7, and the vibration absorption forging head 6 can accurately output the forging point to the forging piece on the forging base 7, thereby ensuring the accuracy of the forging process of the forging piece and reducing the waste rate, wherein, when the clamping mechanism 8 clamps the forging piece, the plastic deformation force generated by the forging piece when the

heated to a set temperature, and the specific range of the temperature can be adjusted according to the type of the forging piece, so that the forging piece can be plastically deformed when it is hammered by the vibration absorption forging head 6, because the original coarse grains are broken and rearranged to form fine and uniform equiaxed grains through plastic deformation of the metal or alloy at high temperature, thereby greatly improving the mechanical properties of the metal or alloy, but the vibration generated by the plastic deformation of the forging piece and the vibration generated by the forging base 7 during the forging process of the forging piece will affect the stability and stress uniformity of the clamping mechanism 8 clamping the forging piece, thereby causing

forging head 6 hammers the forging piece is absorbed by the clamping mechanism 8, which can react on the forging piece and the forging base 7, that is, the vibration effect of the forging piece is reduced, and the vibration effect of the forging base 7 is also reduced, so that the clamping mechanism 8 absorbs a large amount of vibration energy at the moment when the forging piece is hammered by

forging piece, thereby increasing the yield rate of the forging piece during the forging process and greatly reducing the impact force of the entire forging machine, thereby increasing the service life of each component of the forging machine.

[0038] As one embodiment of the present application, Figures 1-9As shown, the forging base 7 includes a moving seat 71, the top surface of the moving seat 71 is fixedly connected with a fixed seat 72, the top surface of the moving seat 71 is provided with an anvil 73 at the center position, it should be noted that the sand is arranged at the inner side position of the top surface of the moving seat 71 close to the fixed seat 72, the anvil 73 can be placed on the sand, when the forging piece on the anvil 73 is subjected to the forging treatment, the anvil 73 will also be subjected to the hammering impact force transmitted by the forging piece, after the anvil 73 is subjected to the hammering impact force, the anvil 73 will act on the sand on the top surface of the moving seat 71, since the sand is composed of a large number of particles, when subjected to the extrusion action of the anvil 73, a large number of particles in the sand will rub against each other to absorb the impact of the anvil 73, thereby reducing the vibration of the anvil 73, so that the anvil 73 can maintain a more stable state after bearing the impact transmitted by the forging piece, the top surface of the forging base 1 is provided with a forging groove 11 at the middle position, the forging groove 11 is matched with the moving seat 71, the top surface of the forging base 1 is fixedly connected with a side plate 12 at the side position close to the moving seat 71, the inside of the forging groove 11 is provided with a base track 13, the bottom surface of the moving seat 71 is fixedly connected with a track sliding block 711 matched with the base track 13 at the position close to the base track 13, the moving seat 71 can freely slide in the forging groove 11 along the direction of the base track 13 through the cooperation of the track sliding block 711 and the base track 13, the bottom surface of the moving seat 71 is installed with a nut 712 at the middle position, the inside of the nut 712 is inserted with a screw rod 713, both ends of the screw rod 713 are connected with a bearing seat 714, the bearing seat 714 is installed on the top surface of the forging groove 11 through bolts, it should be noted that the output shaft of the motor (not shown in the figure) can be connected with the one end of the screw rod 713 through a shaft coupling, when the motor is turned on, the output shaft of the motor can transmit power to the screw rod 713 through the shaft coupling, the rotating screw rod 713 cooperates with the nut 712 fixedly connected with the bottom surface of the moving seat 71, so that the moving seat 71 can move along the track direction of the base track 13 in the forging groove 11, when the forging piece on the top surface of the anvil 73 is finished, the moving seat 71 can be driven by the motor to move to the front end position of the forging base 1 (relative to the left side position of the forging base 1 in the figure), so that the anvil 73 can move out of the inside of the limiting track 2, thereby facilitating the technical personnel to carry the forging piece on the top surface of the anvil 73 and place the new forging piece which has not been forged. Figure 1

[0039] As an embodiment of the present application, as Figure 8 , Figure 9 and Figure 10 ​As shown, the clamping mechanism 8 comprises a driving ring 81 mounted on the top surface of the fixed seat 72, the inner side surface of the driving ring 81 is in a gap with the outer side surface of the anvil 73, the top surface of the driving ring 81 is fixedly connected with a lifting seat 82, the top of the lifting seat 82 is provided with a limiting seat 83, the inner side of the limiting seat 83 is provided with a clamping head 84, and it should be noted that the driving ring 81 is rotatably mounted on the top surface of the fixed seat 72, specifically, three or more than three rollers (not shown in the figure) for supporting the driving ring 81 can be arranged on the top surface of the fixed seat 72, and then a gear slot (not shown in the figure) is formed on the bottom surface of the driving ring 81, and a motor (not shown in the figure) is fixed on the top surface of the fixed seat 72 through a bolt, the output shaft of the motor is engaged with the gear slot on the bottom surface of the driving ring 81 through a gear, when the motor is turned on, the output shaft of the motor can drive the gear slot on the bottom surface of the driving ring 81 through the gear, and the driving ring 81 rotates on the top surface of the fixed seat 72, and the rotating driving ring 81 can drive the forged piece clamped thereon to automatically adjust the position of the forged piece;

[0040] The lifting seat 82 can adopt a hydraulic lifting seat, and it should be noted that the lifting seat in the figure is exaggerated in proportion, and the specific size of the lifting seat is adaptively adjusted according to the required forged piece and the overall specification of the forging machine. The top of the lifting seat 82 is connected with a driving track that can freely lift through a hydraulic rod, and the limiting seat 83 is arranged on the driving track. The lifting seat 82 controls the height of the driving track through the hydraulic rod, that is, the height of the limiting seat 83, and the clamping head 84 is arranged on the limiting seat 83. Therefore, the limiting seat 83 can also control the height of the clamping head 84, so that the clamping head 84 can be clamped at a suitable position on the side surface of the forged piece, such as Figure 10 As shown, the limiting seat 83 can move along the track direction on the driving track, and the driving mode of the limiting seat 83 can adopt a hydraulic mode, an electric mode or a pneumatic mode, as long as the limiting seat 83 can move along the direction of the driving track. The specific adaptive adjustment is made by the person skilled in the art according to the actual situation on site;

[0041] The limiting seat 83 is used to control the position of the clamping head 84 in the horizontal direction, so that the position of the clamping head 84 is stable, Figure 10 The two parallel long rods in the above are used to limit the horizontal position of the clamping head 84, and the limiting seat 83 can also adopt other ways, which are not limited to Figure 10 The way of the two parallel long rods in the above;

[0042] It needs to be emphasized that the number of clamping heads 84 is two, and symmetrically arranged on the limiting seat 83, and the two ends of the limiting seat 83 can be respectively provided with a hydraulic push rod (not shown in the figure). The output end of the hydraulic push rod directly acts on the side surface of the clamping head 84, and the interval between the two clamping heads 84 can be controlled through the hydraulic push rod, so as to realize the clamping operation of the forged piece;

[0043] One of the long rods on the limiting seat 83 can also be replaced by a driving threaded rod, two groups of threads with opposite directions are symmetrically arranged on the side surface of the driving threaded rod, and a threaded groove corresponding to the position is formed in the clamping head 84. Then a motor output shaft (not shown in the figure) is connected to one end of the driving threaded rod through a shaft coupling. When the motor is turned on, the motor output shaft can transmit power to the driving threaded rod. Since two groups of threads with opposite directions are symmetrically arranged on the side surface of the driving threaded rod, the rotating driving threaded rod can make the two clamping heads 84 move towards or away from each other, so as to control the interval between the two clamping heads 84.

[0044] As an embodiment of the present application, as shown in Figure 12 , the clamping head 84 comprises an adjusting block 841, one side of the adjusting block 841 is fixedly connected with a clamping arm 842, a plurality of vibration absorbing blocks 844 are arranged on the inner side surface of the clamping arm 842, and a fastener 843 is arranged between the two clamping arms 842. It needs to be noted that the inner side surface of the clamping arm 842 is an arc surface or an arcuate surface, Figure 12 , the clamping arm 842 in the arcuate surface is convenient to fit the shape of the forged piece, increases the clamping points between the clamping arm 842 and the forged piece, and makes the clamping of the clamping arm 842 more stable. In addition, it needs to be noted that since the clamping arm 842 is an arcuate surface, the vibration absorbing blocks 844 can be uniformly distributed on the arcuate surface of the inner side of the clamping arm 842. When the vibration absorbing blocks 844 contact the forged piece, the direction of the pressure exerted by the vibration absorbing blocks 844 on the side surface of the forged piece will be different. Since the forged piece is subjected to the hammering action of the vibration absorbing forging head 6, the direction of plastic deformation of the forged piece is different. Therefore, the vibration absorbing blocks 844 at different positions are helpful to better absorb the plastic deformation force of the forged piece;

[0045] The fastener 843 is used to lock the position between the two clamping arms 842, as shown in Figure 12 , the fastener 843 can lock the position between the two clamping arms 842 by using a bolt and a nut. Specifically, a circular hole is formed in the clamping arm 842, and the circular hole is matched with the bolt. After the two clamping arms 842 clamp the outer side of the forged piece, the bolt is inserted into the circular hole in the two clamping arms 842, and the position between the two clamping arms 842 is locked by the cooperation of the nut and the bolt, so that the two clamping arms 842 can stably clamp the side surface of the forged piece;

[0046] Since the adjusting block 841 is moved by the hydraulic push rod arranged on the top surface of the limiting seat 83, the fastener 843 can also be arranged at the end of the clamping arm 842 away from the adjusting block 841, specifically, a circular hole is arranged at the end of the clamping arm 842 away from the adjusting block 841, it should be noted that the length of the clamping arm 842 can be increased to ensure that the position of the circular hole does not affect the clamping of the forging, then the bolt is inserted into the circular hole on the two clamping arms 842, and then the position of the two clamping arms 842 is locked by the nut cooperating with the bolt.

[0047] As one embodiment of the present application, as shown in Figure 12 and Figure 13 The inner side of the vibration absorbing block 844 is in sliding abutment with the wedge-shaped block 846, the inside of the clamping arm 842 is arranged with the extrusion cavity 845 near the position of the wedge-shaped block 846, and the inside of the adjusting block 841 is arranged with the hydraulic cavity 847, which is in communication with the extrusion cavity 845, it should be noted that the wedge-shaped block 846 is matched with the inner side surface of the vibration absorbing block 844, when the vibration absorbing block 844 is extruded by the plastic deformation of the forging, the vibration absorbing block 844 will extrude the wedge-shaped block 846 inward, so that the wedge-shaped block 846 can slide in the extrusion cavity 845, the inside of the extrusion cavity 845 is filled with hydraulic oil, and the wedge-shaped block 846 is matched with the extrusion cavity 845, so that when the wedge-shaped block 846 moves, the wedge-shaped block 846 can compress the hydraulic oil in the extrusion cavity 845, since the hydraulic cavity 847 is in communication with the extrusion cavity 845, the wedge-shaped block 846 can compress the hydraulic oil in the extrusion cavity 845 to the inside of the hydraulic cavity 847, so that the hydraulic oil pressure in the hydraulic cavity 847 is increased;

[0048] It should be noted that the oil conveying passage between the hydraulic cavity 847 and the extrusion cavity 845 can be arranged in the inside of the adjusting block 841.

[0049] As one embodiment of the present application, as shown in Figure 12 and Figure 14 The inner side surface of the clamping arm 842 is arranged with the adjusting groove 8421, the adjusting groove 8421 is arranged with the adjusting sliding block 8422, one side of the adjusting sliding block 8422 is threadedly connected with the fastening bolt 8423, and the adjusting sliding block 8422 is arranged with the vibration absorbing block 844, the wedge-shaped block 846 and the extrusion cavity 845, it should be noted that the adjusting sliding block 8422 is matched with the adjusting groove 8421, and can slide freely on the inner side of the adjusting groove 8421, the shape of the adjusting sliding block 8422 and the adjusting groove 8421 is adaptively selected by the person skilled in the art according to the shape of the clamping arm 842, so that the adjusting sliding block 8422 can move on the inner side surface of the clamping arm 842;

[0050] When the two clamping arms 842 clamp the forging piece, the position of the inner side surface adjusting slider 8422 of the clamping arm 842 can be adjusted according to the matching of the clamping arm 842 with the side surface of the forging piece, so that the vibration absorbing block 844 on the adjusting slider 8422 can match the side surface of the forging piece, and the stress points of the vibration absorbing block 844 and the side surface of the forging piece can be matched;

[0051] In addition, it should be noted that a hydraulic push rod can be arranged in the adjusting groove 8421, and the output end of the hydraulic push rod is connected with the adjusting slider 8422, which is used to control the position of the adjusting slider 8422 inside the adjusting groove 8421, that is, the position of the inner side surface of the clamping arm 842;

[0052] The position of the adjusting slider 8422 can be adaptively adjusted according to the acting position of the vibration absorbing forging head 6 on the forging piece. Specifically, after the vibration absorbing forging head 6 performs a hammering operation once, the vibration absorbing forging head 6 will move upward along the limiting rail 2. At this time, the clamping mechanism 8 will re-adjust the position of the forging piece on the anvil 73, so that the vibration absorbing forging head 6 can perform a hammering operation on the forging piece again. The clamping mechanism 8 adjusts the position of the forging piece on the anvil 73 in the following way:

[0053] Through the cooperation of the driving ring 81, the lifting seat 82 and the limiting seat 83, the cooperation mode has been described in detail before, and will not be repeated here. After the clamping mechanism 8 adjusts the position of the forging piece on the anvil 73, in order to freely adjust the position between the two clamping arms 842, when the adjusting groove 8421 and the adjusting slider 8422 are used to control the position of the vibration absorbing block 844 on the clamping arm 842, the fastener 843 is cancelled. In this way, the position between the two clamping arms 842 can be automatically opened by a distance, and then the position of the adjusting slider 8422 can be adjusted according to the next hammering position of the vibration absorbing forging head 6 on the forging piece, so that the adjusting slider 8422 can drive the vibration absorbing block 844 thereon to correspond to the next hammering position of the vibration absorbing forging head 6 on the forging piece, so that the vibration absorbing block 844 can absorb the plastic deformation force of the forging piece caused by the hammering operation to the greatest extent, and improve the effect of the vibration absorbing block 844 absorbing the plastic deformation force of the forging piece caused by the hammering operation;

[0054] As shown in Figure 15 and Figure 16 , the center point of the next hammering position of the vibration absorbing forging head 6 on the forging piece and the shortest distance between the vibration absorbing block 844 on the adjusting slider 8422 can be used as the adjusting position of the vibration absorbing block 844. When the number of adjusting sliders 8422 is more than one, the same is true.

[0055] As an embodiment of the present application, as shown in Figure 11 , Figure 12 and Figure 13As shown, the inner part of the driving ring 81 is provided with an annular oil channel 811, and the inner wall of the driving ring 81 is provided with a plurality of asymmetric extrusion blocks 812, and the annular oil channel 811 is connected with the hydraulic cavity 847, and it should be noted that since the forging part is placed on the top surface of the anvil 73, when the vibration absorption forging head 6 hammers the forging part on the top surface of the anvil 73, the forging part will directly transmit the impact force to the anvil 73, so that the anvil 73 vibrates, and when the forging part is plastically deformed under the hammering of the vibration absorption forging head 6, the plastic deformation of the forging part will directly act on the vibration absorption block 844, so that the vibration absorption block 844 moves away from the forging part, and the moving vibration absorption block 844 acts on the wedge block 846, and since the contact surface between the wedge block 846 and the vibration absorption block 844 is in sliding abutment, the wedge block 846 will have a tendency to move to the extrusion cavity 845 when subjected to the pressure of the vibration absorption block 844, that is, to compress the hydraulic oil in the extrusion cavity 845, and the hydraulic oil in the extrusion cavity 845 will directly enter the hydraulic cavity 847 when compressed, and since the annular oil channel 811 is connected with the hydraulic cavity 847, the hydraulic oil in the hydraulic cavity 847 will also enter the annular oil channel 811, and the oil passage connection mode between the annular oil channel 811 and the hydraulic cavity 847 is adaptively selected by the person skilled in the art according to the spatial position between the annular oil channel 811 and the hydraulic cavity 847, which can ensure that the driving ring 81 and the adjusting block 841 do not interfere with each other, for example, Figure 11 As shown, the inner wall of the driving ring 81 is provided with a plurality of asymmetric extrusion blocks 812, and the inner side of the extrusion block 812 is in contact with the annular oil channel 811, so that the pressure of the hydraulic oil in the annular oil channel 811 will directly act on the extrusion block 812, so that the extrusion block 812 has a tendency to move towards the center, that is, to act on the side surface of the anvil 73, to absorb and limit the vibration of the anvil 73, so that the anvil 73 is more stable during forging of the forging part, and ensures the forging effect of the forging part, and the asymmetrically arranged extrusion blocks 812 can prevent the anvil 73 and the extrusion blocks 812 from resonating.

[0056] As an embodiment of the present application, Figure 6 , Figure 7 and Figure 13As shown, the vibration-absorbing forging head 6 comprises a butt joint seat 61, the bottom surface of the butt joint seat 61 is provided with a damping seat 63, the center position of the bottom surface of the damping seat 63 is fixedly connected with a forging hammer 64, the damping seat 63 comprises an upper damping plate 631 and a lower damping plate 632, the bottom surface of the upper damping plate 631 is provided with a wedge-shaped cavity 633, the top surface of the lower damping plate 632 is fixedly connected with an extrusion plate 634 which is matched with the wedge-shaped cavity 633, the inside of the wedge-shaped cavity 633 is provided with a hydraulic oil bag, the hydraulic oil bag is connected with an external connecting pipe 65, the external connecting pipe 65 is communicated with the hydraulic cavity 847, it should be noted that the position of the butt joint seat 61 close to the lifting rail 22 is provided with a sliding circular hole 62 which is matched with the lifting rail 22, the butt joint seat 61 can realize stable up and down movement through the cooperation of the sliding circular hole 62 and the lifting rail 22, the top surface of the butt joint seat 61 is fixedly connected with the bottom end of the hydraulic shaft 41, specifically, bolted connection can be adopted, in this way, when the hydraulic press 4 is opened, the output power of the hydraulic press 4 can be transmitted to the butt joint seat 61 through the hydraulic shaft 41 to drive the butt joint seat 61 to move, and the bottom surface of the butt joint seat 61 is connected with the forging hammer 64 through the damping seat 63, so that the forging hammer 64 can be driven by the damping seat 63 to move when the butt joint seat 61 moves, so that the forging hammer 64 acts on the forging piece on the top surface of the anvil 73 to realize the forging treatment of the forging piece;

[0057] When the butt joint seat 61 drives the forging hammer 64 to hammer the forging piece, the forging hammer 64 will move downward and finally hammer on the forging piece, at the moment when the forging piece is hammered, the forging hammer 64 will also be subjected to the reaction force of the forging piece, which will be transmitted to the lower damping plate 632, since the top surface of the lower damping plate 632 is fixedly connected with the extrusion plate 634 which is matched with the wedge-shaped cavity 633, the lower damping plate 632 will transmit the reaction force to the extrusion plate 634, so that the extrusion plate 634 moves to the inside of the wedge-shaped cavity 633;

[0058] Since the inside of the wedge-shaped cavity 633 is provided with a hydraulic oil bag, and the hydraulic oil bag is filled with hydraulic oil, when the extrusion plate 634 moves to the inside of the wedge-shaped cavity 633, the hydraulic oil in the hydraulic oil bag will be inevitably extruded, for example Figure 7 As shown, the inside top surface of the wedge-shaped cavity 633 is inclined, when the hydraulic oil in the hydraulic oil bag is extruded to move to the external connecting pipe 65, the hydraulic oil will produce a wedge-shaped effect and react on the extrusion plate 634, in this process, a large amount of reaction force of the forging hammer 64 will be absorbed, the oscillation effect of the forging hammer 64 is reduced, and the hammering effect of the forging hammer 64 on the forging piece is improved, it should be noted that the wedge-shaped cavity 633 and the extrusion plate 634 can be arranged in multiple;

[0059] Since the outer connecting pipe 65 is communicated with the hydraulic cavity 847, the communication mode of the outer connecting pipe 65 and the hydraulic cavity 847 is adaptively adjusted by the person skilled in the art according to the spatial positions of the damping seat 63 and the adjusting block 841, and it is guaranteed that the movement of the damping seat 63 and the adjusting block 841 is not affected;

[0060] When the forging hammer 64 acts on the forged part at the moment, the outer connecting pipe 65 will deliver the pressure of the hydraulic oil generated by the reaction force to the hydraulic cavity 847, so that the pressure of the hydraulic oil in the hydraulic cavity 847 is increased at the moment when the forging hammer 64 acts, and acts in the annular oil channel 811 and the hydraulic cavity 847 respectively. The hydraulic oil pressure of the annular oil channel 811 can act on the side surface of the anvil 73 through the extrusion block 812, so as to reduce the vibration of the anvil 73. The hydraulic oil pressure in the hydraulic cavity 847 can act on the vibration absorbing block 844 through the wedge-shaped block 846, so that the vibration absorbing block 844 acts on the side surface of the forged part, and the plastic deformation force generated by the forged part is greatly absorbed. Not only the clamping effect of the clamping arm 842 on the forged part is improved, but also the scrap rate of the forged part is reduced.

Any equivalent changes and improvements made according to the scope of the present application should still belong to the patent coverage range of the present application.
