DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0031] A large-diameter head spinning forming equipment, such as Figure 1-Figure 3 As shown, it includes a frame 1, an inner rotating wheel 101 is installed in the frame 1, an adjusting block 102 is movably connected in the frame 1, an outer rotating wheel 103 is installed on the adjusting block 102, and a curvature detection mechanism is also included. The curvature detection mechanism includes a mounting frame A201, the mounting frame A201 is fixedly connected to the bottom of the front side of the frame 1, three evenly distributed arc plates 202 are arranged on one side of the mounting frame A201, and a plurality of evenly distributed rolling balls are rollingly connected to one side of the three arc plates 202, and the plurality of rolling balls are used to contact the outer wall of the head. A vertical surface detection mechanism is arranged on the frame 1, and the vertical surface detection mechanism includes a bull's eye ball 203 arranged on the rear side of the frame 1, and the bull's eye ball 203 is used to contact the outer wall of the head. The vertical surface detection mechanism is used to detect the outer wall of the vertical section of the head and further roll it to make the outer wall of the vertical section of the head smoother.

[0032] like Figure 3-Figure 5 As shown, the curvature detection mechanism also includes a slider 301, three sliders 301 are slidably connected in the mounting frame A201, and elastic parts A are arranged between the three sliders 301 and the mounting frame A201, and the elastic parts A are compression springs. The outer walls of the three sliders 301 are all penetrated with T-shaped slots, and elastic telescopic rods 302 are slidably connected in the T-shaped slots. The arc plate 202 is hinged to the telescopic end of the elastic telescopic rod 302, and an elastic part B is arranged between the arc plate 202 and the telescopic end of the elastic telescopic rod 302, and the elastic part B is a torsion spring. A rack 303 used in conjunction with the T-shaped slot is fixedly connected to the bottom of the elastic telescopic rod 302, and an adjustment component 304 connected to the rack 303 is installed on one side of the slider 301. The adjustment component 304 consists of a worm wheel, a worm, a gear and a handwheel, wherein the worm wheel is rotatably connected to one side of the slider 301, the worm is meshed with the lower side of the worm wheel, the gear is fixedly connected to one side of the worm wheel and meshed with the rack 303, and the handwheel is fixedly connected to the end of the worm.

[0033] like Figure 4 As shown, the curvature detection mechanism also includes a trigger switch 401. The inner cavity of the elastic telescopic rod 302 is equipped with the trigger switch 401. The trigger switch 401 is electrically connected to the inner rotating wheel 101, the adjustment block 102 and the outer rotating wheel 103. The trigger switch 401 is used in conjunction with the telescopic end of the elastic telescopic rod 302. When the trigger switch 401 is squeezed, the inner rotating wheel 101 and the outer rotating wheel 103 can increase the spinning force on the head.

[0034] like Figure 5 As shown, it also includes an inclined rod 501, one side of each of the three sliders 301 is fixedly connected to the inclined rod 501, one side of the adjustment block 102 is fixedly connected to a special-shaped frame 502, and the special-shaped frame 502 is rotatably connected to a rotating wheel used in conjunction with the inclined rod 501. When the rotating wheel is lifted upward, the slider 301 can slide horizontally by contacting the special-shaped frame 502.

[0035] like Figure 1As shown, the outer wall of the head is regarded as two parts, the first part is the arc section at the bottom of the head, and the second part is the vertical section at the top of the head. Initially, the three arc plates 202 are on the same vertical line. After the head blank is placed in the frame 1, the curvature detection mechanism is first adjusted. The staff turns the hand wheel in the adjustment component 304, and the hand wheel drives the worm to rotate. The worm drives the gear to rotate through the worm gear. The gear drives the elastic telescopic rod 302 to slide in the slider 301 through the rack 303. The telescopic end of the elastic telescopic rod 302 drives the corresponding arc plate 202 to move horizontally, so that the arrangement position of the three arc plates 202 is consistent with the outer wall cross-section curve of the head finally formed, and then the inner wheel 101, the adjustment block 102 and the outer wheel 103 are started to adjust the arc of the head blank. The shaped segment is spun, and the adjusting block 102 drives the outer rotating wheel 103 to move back and forth (the adjusting block 102, the outer rotating wheel 103 and the movement of the outer rotating wheel 103 driven by the adjusting block 102 are all existing technologies, so they are not described in detail), and the outer wall of the head blank is continuously squeezed. When the adjusting block 102 drives the outer rotating wheel 103 to lift upward, the adjusting block 102 drives the special-shaped frame 502 to move back and forth vertically continuously, and the special-shaped frame 502 drives the rotating wheel thereon to squeeze the lower inclined surface of the lowest inclined rod 501. The inclined rod 501 is forced to drive the corresponding slider 301 to slide, so that the elastic telescopic rod 302 drives the arc plate 202 to move to the side close to the outer wall of the head blank, and the arc plate 202 drives a plurality of rolling balls thereon to contact and squeeze the outer wall of the head blank. The area where the moving ball contacts the outer wall of the head blank is in the same horizontal plane as the spinning position of the outer wheel 103. At this time, the outer wall of the head blank is continuously deformed by the spinning of the inner wheel 101 and the outer wheel 103. However, due to the characteristics of different metal materials, the rebound amplitudes of different metal materials are different when they are spun. After the head blank rebounds, it squeezes a number of rolling balls. The several rolling balls are forced to contract the telescopic end of the elastic telescopic rod 302 through the arc plate 202, and drive the arc plate 202 to rotate with the connection point of the elastic telescopic rod 302 as the center of the circle, so that the several rolling balls fit the outer wall of the head blank. When the arc plate 202 rotates, the elastic part B is forced to contract. Since there is a gap between the telescopic end of the elastic telescopic rod 302 and the trigger switch 401, when the head blank When the rebound amplitude of the material is small, the rebound amplitude is within the acceptable range, and there is no need to adjust the spinning force of the inner wheel 101 and the outer wheel 103, and the telescopic end of the elastic telescopic rod 302 will not contact the corresponding trigger switch 401 after contraction. When the rebound amplitude of the head blank is large, the rebound amplitude exceeds the acceptable range, and the spinning force of the inner wheel 101 and the outer wheel 103 needs to be adjusted to make the head blank meet the standard after forming. At this time, the telescopic end of the elastic telescopic rod 302 contacts and squeezes the trigger switch 401 after contraction. After the trigger switch 401 is squeezed, the spinning force of the inner wheel 101 and the outer wheel 103 is increased, and the head blank is over-extended, so that the size of the head blank after rebound is within the acceptable range. After the head blank is over-extended,After rebounding, the squeezing force on the several rolling balls is weakened, so that the telescopic end of the elastic telescopic rod 302 is away from the trigger switch 401, and the spinning force of the inner wheel 101 and the outer wheel 103 is restored. Then the inner wheel 101, the adjustment block 102 and the outer wheel 103 continue to rise to spin the head blank. When the rotating wheel on the special-shaped frame 502 passes over the top of the lowest inclined rod 501, the lowest inclined rod 501 is free from the restriction and can move. The corresponding slider 301 is retracted and slid back to the original position through the elastic member A between it and the mounting frame A201, so that the lower elastic telescopic rod 302 drives the arc plate 202 to reset, and the elastic member B is released to drive the arc plate 202 to drive the several rolling balls to rotate and reset. Then the special-shaped frame 502 drives the rotating wheel thereon to squeeze the lower inclined surfaces of the other two inclined rods 501 in turn, and achieves the same effect as above, thereby completing the spinning work of the arc segment of the head blank. Example 2

[0036] like Figure 6 As shown, the vertical plane detection mechanism also includes a contact rod A601, the contact rod A601 is fixedly connected to one side of the adjustment block 102, a contact rod B602 used in conjunction with the contact rod A601 is arranged on the upper side of the contact rod A601, a guide rail 603 is fixedly connected to the rear side of the frame 1, a slide bar 604 is vertically slidably connected inside the guide rail 603, the contact rod B602 is fixedly connected to the slide bar 604, and when the contact rod A601 squeezes the contact rod B602, the slide bar 604 can move vertically.

[0037] like Figure 6 As shown, the vertical plane detection mechanism also includes a mounting plate 701, a hydraulic cylinder A7011 is installed at one end of the sliding rod 604, the telescopic end of the hydraulic cylinder A7011 is fixedly connected to the mounting plate 701, a sensor 702 is installed on the mounting plate 701, the sensor 702 is electrically connected to the inner rotating wheel 101, the adjustment block 102 and the outer rotating wheel 103, the sensor 702 can accurately adjust the rotational pressure of the inner rotating wheel 101 and the outer rotating wheel 103 according to the squeezing force, the bull's eye ball 203 is movably connected to the mounting plate 701, and an elastic member C is arranged between the mounting plate 701, and the elastic member C is a compression spring.

[0038] like Figure 7-8 As shown, it also includes a vertical rod 801, the bottom of the sliding rod 604 is fixedly connected with the vertical rod 801, the rear side of the frame 1 is rotatably connected with a connecting rod 802, the connecting rod 802 is provided with a guide groove A and a guide groove B, the bottom end of the vertical rod 801 is inserted into the guide groove A and slides in the guide groove A, and a pressurized piston cylinder 803 is installed on the rear side of the frame 1, the telescopic end of the pressurized piston cylinder 803 is inserted into the guide groove B and slides in the guide groove B. When the vertical rod 801 is lifted upward, the vertical rod 801 contracts the telescopic end of the pressurized piston cylinder 803 through the connecting rod 802, and the inner cavity of the pressurized piston cylinder 803 is filled with hydraulic oil for promoting the telescopic end of the hydraulic cylinder B902 to move.

[0039] As Figure 7 shown, it further includes an L-shaped frame 901. The L-shaped frame 901 is fixedly connected to the rear side of the frame 1. A hydraulic cylinder B902 is installed on one side of the L-shaped frame 901. The inner cavity of the pressurizing piston cylinder 803 is communicated with the inner cavity of the hydraulic cylinder B902 through an oil injection pipe. When the telescopic end of the pressurizing piston cylinder 803 contracts, the hydraulic oil in its inner cavity is injected into the inner cavity of the hydraulic cylinder B902 through the oil injection pipe. The telescopic end of the hydraulic cylinder B902 is fixedly connected with a U-shaped frame, and an adjusting roller 903 for contacting the head is rotatably connected in the U-shaped frame.

[0040] Before spinning the head blank, the staff will first add an appropriate amount of hydraulic oil into the pressurized piston cylinder 803 according to the diameter of the vertical section of the head. It is worth noting that the hydraulic oil injected into the pressurized piston cylinder 803 will eventually enter the hydraulic cylinder B902. The larger the diameter of the vertical section of the head, the shorter the extension length of the telescopic end of the hydraulic cylinder B902, and the less the amount of hydraulic oil added. On the contrary, when the inner rotating wheel 101 and the outer rotating wheel 103 rise to the vertical section of the head blank, the adjustment block 102 drives the contact rod A601 to squeeze the contact rod B602, and the contact rod B602 is forced to drive the sliding rod 604 to lift upward, and the sliding rod 604 drives the hydraulic cylinder A7011 and the vertical rod 801 to lift upward, and the hydraulic cylinder A7011 drives The movable mounting plate 701 is lifted upward, and the bottom end of the vertical rod 801 squeezes the inner wall of the guide groove A of the connecting rod 802. The connecting rod 802 is forced to rotate with the connection point of the frame 1 as the center, so that the inner wall of the guide groove B squeezes the telescopic end of the pressurized piston cylinder 803. The telescopic end of the pressurized piston cylinder 803 is forced to shrink and injects the hydraulic oil in its inner cavity into the hydraulic cylinder B902 through the oil injection pipe. It is worth noting that, initially, the height of the telescopic end of the pressurized piston cylinder 803 is a fixed value, and the height of the telescopic end of the pressurized piston cylinder 803 will not change according to the dosage of the hydraulic oil in its inner cavity. When the telescopic end of the pressurized piston cylinder 803 shrinks, until the telescopic end of the pressurized piston cylinder 803 contacts the hydraulic oil in its inner cavity, the hydraulic oil is injected into the hydraulic cylinder B902 through the oil injection pipe. The bull's eye ball 203 and the sensor 702 are lifted upward, and the hydraulic cylinder A7011 is started. The hydraulic cylinder A7011 drives the bull's eye ball 203 to contact the outer wall of the head blank through the mounting plate 701. The bull's eye ball 203 detects the rebound amplitude of the outer wall of the vertical section of the head blank. During this process, the head blank rotates and drives the bull's eye ball 203 to roll. The bull's eye ball 203 will not scratch the outer wall of the head blank. Since the vertical section of the head needs to produce a larger plastic deformation than the arc section, the inner and outer rotating wheels 101 and 103 have a greater spinning force on the head blank. After the head blank rebounds, it squeezes the bull's eye ball 203. The bull's eye ball 203 is forced to slide on the mounting plate 701, and the elastic member C is forced to shrink. The bull's eye ball 203 squeezes the sensor 702, and the sensor 702 detects the force of the bull's eye ball 203. When the rebound amplitude of the head blank is small, the rebound amplitude is within the acceptable range, and the squeezing force of the bull's eye ball 203 on the sensor 702 is within the acceptable range, and there is no need to adjust the spinning force of the inner and outer wheels 101, 103. When the rebound amplitude of the head blank is large, the rebound amplitude exceeds the acceptable range, and the spinning force of the inner and outer wheels 101, 103 needs to be adjusted. At this time, the increased force is greater than the increased force after the trigger switch 401 is squeezed, so that the head meets the standard after forming. At this time, the sensor 702 controls the spinning force of the inner and outer wheels 101, 103 to increase, and the head blank is over-extended.Thus, the size of the head blank after rebound is within an acceptable range. When the head blank rebounds within the normal range, the head blank no longer squeezes the bull's eye ball 203, and the bull's eye ball 203 no longer squeezes the sensor 702, so that the spinning force of the inner wheel 101 and the outer wheel 103 is constant, and then the inner wheel 101, the adjustment block 102 and the outer wheel 103 continue to rise to spin the head blank. When the bull's eye ball 203 passes over the top of the head, the telescopic end of the hydraulic cylinder B902 drives the adjustment roller 903 through the yoke to contact and roll the outer wall of the vertical section of the head, so that the outer wall of the vertical section of the head is smoother, thereby completing the spinning forming work of the head.

[0041] Then the inner wheel 101, the adjustment block 102 and the outer wheel 103 are reset, the adjustment block 102 drives the contact rod A601 to fall and reset, the contact rod A601 no longer squeezes the contact rod B602, the slide bar 604 falls and slides in the guide rail 603 under its own weight to reset, and then the vertical rod 801 and the mounting plate 701 fall and reset, the mounting plate 701 drives the bull's eye ball 203 away from the head blank, and then the elastic member C drives the bull's eye ball 203 away from the sensor 702, the vertical rod 801 squeezes the guide groove A of the connecting rod 802, The connecting rod 802 rotates to drive the telescopic end of the pressurized piston cylinder 803 to extend and reset. The pressurized piston cylinder 803 draws out the hydraulic oil in the hydraulic cylinder B902 through the oil filling pipe, so that the telescopic end of the hydraulic cylinder B902 is reset, and then the adjustment roller 903 is reset, thereby completing the processing and resetting of the entire equipment. Through the cooperation of the curvature detection mechanism and the vertical surface detection mechanism, the equipment can adaptively adjust the spinning intensity of the inner and outer rotating wheels according to the rebound amplitude of various metal materials, thereby greatly improving the accuracy of the head spinning.

[0042] A process for a large-caliber head spinning forming device includes the following steps:

[0043] S1: When using the device, the outer wall of the head is regarded as two parts, the first part is the arc section at the bottom of the head, and the second part is the vertical section at the top of the head. The head blank is placed in the frame 1. First, according to the curvature of the arc section of the head, the positions of the plurality of arc plates 202 are adjusted through the adjustment component 304, so that the plurality of arc plates 202 are distributed according to the curvature of the arc section of the head, and hydraulic oil is injected into the pressurized piston cylinder 803 according to the height of the vertical section of the head;

[0044] S2: Start the inner and outer wheels 101 and 103 to spin the head blank. When the arc segment of the head blank is spun, the plurality of arc plates 202 move synchronously with the rise of the outer wheel 103, detect the rebound amplitude of the outer wall of the arc segment, and adjust the spinning intensity of the outer wheel 103 according to the detection result;

[0045] S3: When the vertical section of the head blank is spun, the bull's eye ball 203 moves synchronously with the rise of the outer rotating wheel 103, the rebound amplitude of the outer wall of the vertical section is detected, and the spinning intensity of the outer rotating wheel 103 is adjusted according to the detection result. When the spinning is completed, the adjustment roller 903 contacts the outer wall of the vertical section of the head blank for rolling to make the vertical section smoother.

[0046] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
