[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] Please also read Figures 1 to 7, the anti-displacement forging machine of the present invention is described. An anti-displacement forging machine includes a roll forging machine and an adjusting machine arranged on both sides of the roll forging machine along a first path, the roll forging machine includes a frame (not shown) and two rollers 10 symmetrically connected to the frame along the up and down directions, the adjusting machine includes two anti-bias units distributed along the first path in mirror symmetry, a receiving space for receiving the adjusting machine is formed between the two anti-bias units, the anti-bias unit includes an anti-bias frame 20 and two groups of anti-bias components; the two groups of anti-bias components are respectively connected to the anti-bias frame 20 along the second path, a limiting space for receiving a workpiece is formed between the two groups of anti-bias components, the anti-bias components include a driving mechanism 30 and a limiting mechanism 40 connected to the driving mechanism 30, the limiting mechanism 40 is used to abut against the workpiece on the second path, and the driving mechanism 30 is used to drive the limiting mechanism 40 to maintain a relatively static state with the workpiece.

[0021] In the anti-displacement forging machine provided in this embodiment, when the workpiece passes through the roller 10, the workpiece is axially squeezed by the roller 10 to produce axial stretching. At this time, the driving mechanism 30 adjusts the movement speed of the limiting mechanism 40 in real time to keep it relatively still with the workpiece.

[0022] Compared with the prior art, the two groups of anti-bias units are distributed in mirror symmetry on both sides of the roll forging machine, the middle part of the workpiece is located between the two rollers of the roll forging machine, and the two ends correspond to the two groups of anti-bias units respectively. The limiting mechanisms 40 of the two groups of anti-bias units abut against the workpiece, thereby preventing the workpiece from being radially offset during the conveying process. In addition, under the action of the driving mechanism 30, the limiting mechanism 40 maintains a relatively static state with the workpiece to avoid scratches on the surface of the workpiece caused by relative movement. The anti-bias unit of the present invention applies a bidirectional balanced restraining force to the workpiece during the forging process, offsets the unilateral torque generated when the roller 10 is pressed down, avoids warping or rotational offset of the workpiece due to uneven force, and keeps the workpiece in the center of the limiting space during the forging process, effectively suppressing the lateral displacement caused by the pressure of the roller 10, and improving the forging forming accuracy; the linkage design of the driving mechanism 30 and the limiting mechanism 40 realizes the relative static state of the limiting mechanism 40 and the workpiece to avoid scratches caused by friction.

[0023] In some embodiments, see Figure 2 and Figure 3 The driving mechanism 30 includes two sprockets 301, a driving member 302 and a chain 303. The two sprockets 301 are spaced apart along the first path and are rotatably connected to the anti-bias frame 20 respectively. The driving member 302 is connected to one of the sprockets 301 to drive the sprocket 301 to rotate around its own axis. The chain 303 is wound around the outer periphery of the two sprockets 301, and the limiting mechanism 40 is fixedly connected to the outer side of the chain 303.

[0024] The anti-deviation assembly also includes a guide frame 201 arranged around the outer periphery of the chain 303, the guide frame 201 is fixedly connected to the anti-deviation frame 303, the limiting mechanism 40 is slidably connected to the guide frame 201, and the guide frame 201 is used to guide the sliding fit of the moving path of the limiting mechanism 40.

[0025] The limiting mechanism 40 includes a slide 401, a side top piece 402 and a positioning plate 403. The slide 401 is connected to the outer side of the chain 303; the side top piece 402 is connected to the slide 401 and is located on opposite sides of the slide 401 with the chain 303 respectively, and the side top piece 402 is telescopic along the second path; the positioning plate 403 is detachably connected to the telescopic end of the side top piece 402.

[0026] Specifically, the driving member 302 may be a motor, the side top member 402 may be a telescopic oil cylinder, a hydraulic cylinder, or an electric cylinder, the end of the side top member 402 is fixedly connected with a mounting plate, and the positioning plate 403 is screwed to the mounting plate.

[0027] It should be noted that the positioning plate 403 can be changed according to the shape of the workpiece. The positioning plate 403 can be an arc-shaped plate or a flat plate.

[0028] The driving member 302 drives the sprocket wheel 301 to rotate, and drives the positioning plate 403 on the chain 303 to move along the second path, so that the lateral position of the workpiece will not be offset.

[0029] Two groups of anti-deviation components are distributed along the second path to form a limiting space constrained by two orthogonal directions. When the workpiece undergoes local deformation due to differences in material fluidity, the limiting mechanism 40 can dynamically adjust the contact pressure on the second path through the extension and retraction of the side top piece 402, thereby suppressing drum deformation or folding defects and improving the uniformity of the forging wall thickness.

[0030] The guide frame 201 and the chain 303 form a dual guide system, which not only ensures the motion trajectory accuracy of the positioning plate 403, but also shares the lateral load of the chain 303. The guide frame 201, as a rigid support, effectively suppresses the vibration of the chain 303, eliminates the positioning jitter caused by the gap between the chain links, and makes the positioning plate 403 more stable when it is pressed against the workpiece.

[0031] The limit contact surface can be customized according to the shape of the workpiece. During the replacement process, there is no need to dismantle the main structure, and only the positioning plate 403 needs to be replaced.

[0032] In some embodiments, see Figure 1 and Figure 3The anti-deviation unit also includes an adjustment mechanism 50 connected to the driving mechanism 30, and the adjustment mechanism 50 includes a transmission member, a switching member and an adjustment member. The switching member is connected to the anti-deviation frame 20 and is located below the driving mechanism 30; the transmission member is connected to the switching member, and the top of the transmission member has a plug-in block for plugging with the driving mechanism 30, and the bottom has a transmission gear 5032; the switching member enables the transmission member to have an adjustment state of plugging with the driving mechanism 30, and a fixed state separated from the driving mechanism 30; the adjustment member includes a connecting shaft 504 and an adjustment gear 5041 coaxially connected to the connecting shaft 504, and also includes a pulley 505 connected to the connecting shaft 504, the adjustment gear 5041 is meshed with the transmission gear 5032, the connecting shaft 504 is rotatably connected to the anti-deviation frame 20, and the pulley 505 is used to provide support force for the anti-deviation frame 20.

[0033] Specifically, the adjustment gear 5041 and the transmission gear 5032 are both bevel gears.

[0034] It should be noted that there are multiple and identical grooves on the rolling roller 10 along the left-right direction, the number of the grooves is odd, and the workpiece passes through multiple grooves in sequence to complete the roll forging; when the front and rear sides are roll forged, the moving directions of the workpiece are opposite, and the moving direction of the workpiece in the left-right direction can be changed by changing the direction of the motor.

[0035] Through the meshing transmission of the transmission gear 5032 and the adjustment gear 5041, the rotational motion of the sprocket 301 drive system is converted into the linear displacement of the pulley 505 along the slide rail 60, compensating for the wear of the sprocket 301 or the deformation of the slide rail 60 caused by long-term use of the equipment, thereby ensuring the symmetry of the limited space; the adjustment state and the fixed state of the switching member are realized through a purely mechanical structure to achieve mode switching, without the need for electrical control, and is particularly suitable for high-frequency production change scenarios.

[0036] In some embodiments, see Figure 4 and Figure 5The switching member includes a transmission column 501 and a transmission shaft 502 arranged above the transmission column 501. The transmission column 501 is slidably connected to the anti-bias frame 20 in the up-down direction. The top of the transmission column 501 is provided with a first transmission cavity 5011, and the bottom is provided with a second transmission cavity 5012. The inner wall of the first transmission cavity 5011 is provided with a spiral first turning groove 5013 and a first return groove 5014 connected to the first turning groove 5013. The first return groove 5014 extends in the up-down direction. The inner wall of the second transmission cavity 5012 is provided with a spiral first turning groove 5013 and a first return groove 5014 connected to the first turning groove 5013. The first return groove 5014 extends in the up-down direction. A spiral second steering groove 5015 and a second return groove 5016 connected to the second steering groove 5015 are provided, and the second return groove 5016 extends in the up-down direction; the top end of the transmission shaft 502 is fixedly connected to the center of the sprocket 301, and the bottom end is inserted into the first transmission cavity 5011, and the outer wall of the transmission shaft 502 is provided with a first steering block 5021, and the bottom end of the transmission shaft 502 extends into the first transmission cavity 5011, and the first steering block 5021 slides in the first steering groove 5013 and the first return groove 5014.

[0037] The transmission member 503 is rotatably connected to the anti-bias frame 20 around its own central axis, and a second steering block 5031 is provided on the outer wall of the transmission member 503. The transmission member 503 is plug-fitted with the second transmission cavity 5012, and the second steering block 5031 is slidably fitted in the second steering groove 5015 and the second return groove 5016.

[0038] When the first steering block 5021 enters the first return groove 5014 , the second steering block 5031 also starts to enter the second return groove 5016 , and at this time, the transmission column 501 moves upward to the original position.

[0039] An elastic reset member 202 is further provided between the transmission column 501 and the anti-bias frame 20, and the elastic reset member 202 is configured with a pre-tightening force to keep the transmission column 501 and the second transmission cavity 5012 in a separated state. Specifically, the elastic reset member 202 can be a spring rod.

[0040] It should be noted that the depth of the second transmission cavity 5012 is adjusted according to actual needs to ensure that the transmission member 503 is inserted into the second transmission cavity 5012 while the workpiece completes one roll forging.

[0041] The rotation of the sprocket 301 drives the transmission shaft 502 to rotate, and the rotation of the transmission shaft 502 causes the first steering block 5021 to rotate along the first steering groove 5013. Since the transmission column 501 is restricted from rotating, the transmission column 501 moves downward, and at this time the transmission column 501 is not in contact with the transmission member 503; after completing one roll forging, the transmission column 501 continues to move downward, so that the transmission member 503 is inserted into the second transmission cavity 5012. At this time, the second steering block 5031 slides along the second steering groove 5015. Since the transmission member 503 cannot move up and down, the transmission member 503 rotates; when the workpiece is moved in the left and right directions, the first steering block 5021 begins to enter the first return groove 5014, and the second steering block 5031 begins to enter the second return groove 5016, and then the elastic reset member 202 releases the elastic force to cause the transmission column 501 to move upward and return to its original position.

[0042] Another modified embodiment of the adjustment mechanism 50 is that the adjustment mechanism 50 includes a switching member, which is a pneumatic or hydraulic telescopic member that can be extended and retracted in the up and down directions. In the adjustment state, the plug block is plugged into the drive mechanism 30, and in the fixed state, the plug block is separated from the drive mechanism 30.

[0043] The switching part is changed to a hydraulic cylinder or an air cylinder, and the plug block is connected or separated from the drive mechanism 30 through telescopic movement. The power source is an external hydraulic station or air compressor, and control valves and sensors need to be configured, which increases the equipment footprint. The risk of hydraulic oil leakage requires regular maintenance, which increases the operating cost. In addition, the hydraulic oil is prone to deterioration in a high temperature environment, and a cooling system needs to be installed. The air pressure drive is prone to condensation in a humid environment, causing air circuit corrosion. The hydraulic system has a delay caused by the compressibility of the oil, and the real-time performance of dynamic adjustment is limited.

[0044] The axial motion is converted into rotational motion by the up and down sliding of the transmission column 501 and the cooperation with the spiral groove, so as to realize the meshing or disengagement of the transmission gear 5032 and the adjustment gear 5041. The switching action relies on pure mechanical linkage, does not require an external power source, has no leakage risk, and is suitable for high temperature and high vibration forging environments; the hard contact between the spiral groove and the steering block transmits power and has strong overload resistance; there is no consumption of hydraulic oil or compressed air, and the operating cost is reduced; there is no hydraulic system delay, and the dynamic adjustment is highly real-time.

[0045] In one embodiment, see Figure 6 The anti-deviation assembly also includes a slide rail 60 disposed below the anti-deviation frame 20 , and the pulley 505 is rotatably disposed in the slide rail 60 .

[0046] Specifically, the slide rail 60 is provided with a first avoidance groove 601 for the connecting shaft 504 to pass through, and the first avoidance groove 601 extends along the second path. The inner wall of the first avoidance groove 601 is provided with a storage cavity 602, and the storage cavity 602 extends along the second path. A fastening plate 603 is arranged in the storage cavity 602, and the fastening plate 603 extends along the second path. A lifting member 604 is installed on the inner wall of the storage cavity 602, and the lifting member 604 is retracted in the up and down directions.

[0047] It should be noted that the lifting member 604 can be a telescopic cylinder, a hydraulic cylinder, or an electric cylinder.

[0048] When the pulley 505 rotates, the pulley 505 can move along the slide rail 60, and the slide rail 60 guides the pulley 505 so that the moving direction of the pulley 505 will not deviate; when the pulley 505 does not rotate, the lifting member 604 extends to drive the fastening plate 603 to press against the connecting shaft 504, so that the connecting shaft 504 will not rotate, and then the pulley 505 will not rotate, thereby improving the static stability of the anti-skew frame 20.

[0049] In one embodiment, see Figure 7 The anti-deviation assembly also includes a slide rail 60 disposed below the anti-deviation frame 20 , and the pulley 505 is rotatably disposed in the slide rail 60 .

[0050] Specifically, the slide rail 60 is provided with a second avoidance groove 605 for the connecting shaft 504 to pass through, and the second avoidance groove 605 extends along the second path. The inner wall of the second avoidance groove 605 is slidably connected to the limiting seat 606 along the second path. The limiting seat 606 has an upper protrusion 6061 extending upward and a lower protrusion 6062 extending downward. The upper protrusion 6061 has an avoidance hole for the connecting shaft 504 to pass through, and a fastener 6063 is installed on the lower protrusion 6062, and the fastener 6063 is retracted along the front and rear directions.

[0051] It should be noted that the fastener 6063 can be a telescopic cylinder, a hydraulic cylinder, or an electric cylinder.

[0052] When the pulley 505 is not rotating, the fastener 6063 is extended to press against the outer side wall of the slide rail 60 , thereby improving the static stability of the anti-skew frame 20 .

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
