Description

Technical Field

[0001] The invention relates to the technical field of spinning machines, in particular to a vertical spinning machine with a safety protection structure. Background Art

[0002] The working principle of the spinning machine is to place the workpiece between the mold and the pressure head, and then clamp the workpiece after the pressure head moves. Then the main machine drives the mold, workpiece and pressure head to rotate at the same time. At the same time, the rotating roller is used to squeeze the surface of the workpiece to achieve the shaping of the workpiece. Since the workpiece keeps rotating at a high speed during the processing, some thicker workpieces need to be heated. Therefore, if the workpiece falls off during the processing, it will be thrown out at a high speed, which is extremely dangerous. Ensuring the clamping strength between the pressure head and the mold is an important factor to prevent the workpiece from accidentally falling off. The current spinning machine equipment lacks mandatory safety protection measures for the clamping strength of the workpiece when fixing the workpiece, which makes it easy for the workpiece to detach during the processing, posing a great safety hazard.

DETAILED DESCRIPTION

[0032] 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.

[0033] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a vertical spinning machine with a safety protection structure.

[0034] Example 1: Please refer to Figure 1-Figure 6 A vertical spinning machine with a safety protection structure comprises a main body 1, a processing chamber 2 is arranged on the main body 1, a housing 3 and a hydraulic cylinder 4 are fixed to the inner bottom wall and the inner top wall of the processing chamber 2 respectively, a motor 5 is fixed inside the housing 3, and a mold 9, a pressing head 10, a clutch assembly 6, a transmission assembly 7 and a pressure feedback assembly 8 are also arranged in the processing chamber 2;

[0035] The mold 9 is movably mounted on the top of the housing 3, and the pressure head 10 is movably mounted on the bottom of the hydraulic cylinder 4 and is located directly above the mold 9;

[0036] The hydraulic cylinder 4 is connected to the pressure head 10 through the pressure feedback component 8, and is used to drive the pressure head 10 to move toward the mold 9 to clamp the workpiece.

[0037] The motor 5 is connected to the output shaft of the motor 5 through the clutch assembly 6, and is used to drive the mold 9 to rotate, thereby driving the mold 9 and the workpiece on the mold 9 to rotate;

[0038] The pressure feedback assembly 8 is connected to the clutch assembly 6 through the transmission assembly 7. The pressure feedback assembly 8 is used to monitor the pressure of the pressure head 10 on the workpiece, and the clutch assembly 6 is used to control the connection or disconnection of the driving force of the motor 5 on the mold 9;

[0039] Before processing, the hydraulic cylinder 4 drives the pressure head 10 to move downward when it is running, and cooperates with the mold 9 to clamp the workpiece. At the same time, the pressure feedback component 8 runs and monitors the pressure of the pressure head 10 on the workpiece. When the pressure does not reach the standard value, the driving force of the motor 5 on the mold 9 is disconnected, so that the mold 9 cannot be driven. When the pressure reaches the standard value, the pressure feedback component 8 drives the clutch component 6 to operate through the transmission component 7. After the clutch component 6 operates, the driving force of the motor 5 on the mold 9 is connected, so that the mold 9 can be driven.

[0040] Among them, the output end of the hydraulic cylinder 4 is arranged vertically downward, and the workpiece needs to be placed horizontally on the top of the mold 9 before processing the workpiece. The clutch assembly 6 is disconnected by default, so that the driving force of the motor 5 cannot be transmitted to the mold 9, and thus the mold 9 cannot be driven to rotate;

[0041] When in use, first start the hydraulic cylinder 4. After the hydraulic cylinder 4 is extended, it drives the pressure head 10 and the pressure feedback component 8 to move downward. When the pressure head 10 contacts the workpiece, the pressure feedback component 8 monitors the pressure of the pressure head 10 on the workpiece. If the pressure does not reach the standard, the clutch component 6 is still in a disconnected state, and the driving force of the motor 5 cannot be transmitted to the mold 9 through the clutch component 6. Therefore, the mold 9 cannot rotate, and the spinning operation cannot be performed. When the pressure reaches the standard, the pressure feedback component 8 operates and drives the transmission component 7. The transmission component 7 drives the clutch component 6, so that the clutch component 6 is converted to a connected state. At this time, the driving force of the motor 5 can be transmitted to the mold 9 through the clutch component 6, and then the motor 5 is started. When the motor 5 operates, it drives the mold 9 to rotate through the clutch component 6. When the mold 9 rotates, it drives the clamped workpiece and the pressure head 10 to rotate, and then the spinning operation of the workpiece is performed;

[0042] By setting a pressure feedback component 8, a transmission component 7 and a clutch component 6 in a default disconnected state, the pressure feedback component 8 is used to monitor the clamping force of the pressure head 10 on the workpiece. At the same time, the pressure feedback component 8 can also drive the clutch component 6 to operate through the transmission component 7. Only when the clamping force of the workpiece meets the standard value can the clutch component 6 be driven to switch to the connected state, so that the motor 5 can drive the mold 9 to rotate. In this way, it is beneficial to ensure that the clamping force of the workpiece is sufficient before the spinning work, avoid the situation where the workpiece is detached and thrown out during the processing due to insufficient clamping force, and reduce safety hazards.

[0043] Example 2: See Figure 2-Figure 5 , which is different from the above embodiment, the clutch assembly 6 includes a movable seat 601, the movable seat 601 penetrates the top wall of the shell 3 and is rotatably connected to the top wall of the shell 3, the top of the movable seat 601 is fixed to the bottom of the mold 9, the bottom of the movable seat 601 is fixedly connected to a vertical shaft 602, the outer sleeve of the vertical shaft 602 is provided with a shaft sleeve 603, the shaft sleeve 603 is vertically slidably connected to the vertical shaft 602, the bottom end of the shaft sleeve 603 is fixedly connected to an upper tooth block 604, the bottom of the upper tooth block 604 is provided with a lower tooth block 605, the lower tooth block 605 is fixed to the output shaft of the motor 5, the outer side of the shaft sleeve 603 is rotatably connected to a collar 606, and the outer wall of the collar 606 is fixedly connected to two symmetrically arranged pins 607, A push spring 608 is fixed to the top of the collar 606, and a bracket 609 is fixedly connected to the top of the push spring 608. The bracket 609 is fixedly connected to the top wall of the shell 3. The bracket 609 and the push spring 608 are both sleeved on the outside of the vertical shaft 602. A through slot 31 is provided on the side wall of the shell 3. The clutch assembly 6 also includes a base shaft 610 rotatably connected to the through slot 31. A driven bevel gear 611 and a support rod 612 are fixed to the base shaft 610. An arc fork frame 613 is fixed to the end of the support rod 612 away from the base shaft 610. Both ends of the arc fork frame 613 are provided with strip holes 614. The two ends of the arc fork frame 613 are respectively sleeved on two latches 607 through the strip holes 614.

[0044] The surface of the vertical shaft 602 is provided with a guide groove, and the inner wall of the shaft sleeve 603 is provided with a guide block matching the guide groove. The guide groove and the guide block are both arranged vertically, so as to realize the sliding connection between the shaft sleeve 603 and the vertical shaft 602. The bottom of the upper tooth block 604 and the top of the lower tooth block 605 are both provided with a plurality of arc-shaped ratchets distributed in a circular array. In the initial state, the upper tooth block 604 is located between the lower tooth block 605 and a gap is provided.

[0045] When in use, the motor 5 runs and drives the lower tooth block 605 to rotate. Since the upper tooth block 604 is not meshed with the lower tooth block 605 in the initial state, the driving force cannot be transmitted to other parts through the upper tooth block 604, and the mold 9 cannot be driven to rotate, and the mold 9 cannot perform the spinning operation; when the base shaft 610 rotates, it drives the support rod 612 to swing, and the support rod 612 drives the arc fork frame 613 at one end to swing. When the arc fork frame 613 swings, the inner wall of the strip hole 614 pushes the pin 607, so that the ring 606 moves down, and the ring 606 pulls the pin 607 when it moves down. The long push spring 608 drives the shaft sleeve 603 to move downward, and the shaft sleeve 603 slides downward along the vertical shaft 602 at this time, and drives the upper tooth block 604 to move downward. When the upper tooth block 604 moves to mesh with the lower tooth block 605, the motor 5 drives the lower tooth block 605 to rotate. At this time, the lower tooth block 605 drives the upper tooth block 604 to rotate. When the upper tooth block 604 rotates, it drives the vertical shaft 602 to rotate. When the vertical shaft 602 rotates, it drives the movable seat 601 to rotate. When the movable seat 601 rotates, it drives the mold 9 to rotate, and the mold 9 can perform normal spinning operation;

[0046] By setting the clutch assembly 6, since the upper tooth block 604 and the lower tooth block 605 are set to a separated state by default, the driving force of the motor 5 cannot be transmitted to the mold 9. At the same time, when the base shaft 610 drives the support rod 612 and the arc-shaped fork frame 613 to swing, it can push the upper tooth block 604 and the lower tooth block 605 to engage, which is conducive to connecting or disconnecting the driving force through the engagement and separation of the upper tooth block 604 and the lower tooth block 605, so as to connect or disconnect the driving force between the motor 5 and the mold 9 according to needs.

[0047] Example 3, see Figure 2 and Figure 6 , which is different from the above embodiment, the pressure feedback component 8 includes a fixed plate 801, the fixed plate 801 is fixedly connected to the output end of the hydraulic cylinder 4, an upper pressure block 802 is installed on the edge of the fixed plate 801, a pressure sensor 803 is fixedly connected to the bottom of the fixed plate 801, a pressure spring 804 is fixedly connected to the pressure surface at the bottom of the pressure sensor 803, a movable plate 805 is fixedly connected to the bottom end of the pressure spring 804, a plurality of guide rods 806 are fixedly connected to the top of the movable plate 805, and the plurality of guide rods 806 are movably plugged with the fixed plate 801, a mounting rod 807 is fixedly connected to the bottom end of the movable plate 805, and the bottom end of the mounting rod 807 is rotatably connected to the top of the pressure head 10;

[0048] Among them, the guide rods 806 are preferably set to four, and the four guide rods 806 are distributed in a circular array. When in use, the hydraulic cylinder 4 drives the entire pressure feedback assembly 8 and the pressure head 10 to move downward when it is extended. When the pressure head 10 contacts the workpiece, it stops moving. At this time, the mounting rod 807, the movable plate 805 and the guide rod 806 on the pressure head 10 are all stationary. The hydraulic cylinder 4 continues to extend and drives the fixed plate 801 and the pressure sensor 803 to continue to move downward. When the fixed plate 801 moves downward, it drives the upper pressure block 802 on the edge to move downward. When the pressure sensor 803 moves downward, the pressure spring 804 is compressed. After the pressure spring 804 is deformed, it applies pressure to the movable plate 805, and then acts on the workpiece through the pressure head 10. The pressure spring 804 also applies pressure to the pressure sensor 803, so as to realize the monitoring of the clamping force of the workpiece. The greater the extension of the hydraulic cylinder 4, the greater the deformation of the pressure spring 804, and the greater the pressure acting on the workpiece through the pressure head 10.

[0049] By setting up the pressure feedback component 8, when compressing the pressure spring 804, pressure is also applied to the workpiece at the bottom of the pressure head 10, thereby increasing the clamping force on the workpiece. At the same time, the pressure spring 804 also applies pressure to the pressure sensor 803 to monitor the pressure value.

[0050] Example 4, see Figure 7 and Figure 8, different from the above embodiment, the transmission assembly 7 includes a vertical rod 701, the top of the vertical rod 701 is fixedly connected to the top wall of the processing chamber 2, a vertical slide groove 702 is opened on the surface of the vertical rod 701, a strip slider 703 is slidably connected to the vertical slide groove 702, a return spring 704 is fixedly connected to the top of the strip slider 703, one end of the return spring 704 is fixedly connected to the top of the vertical slide groove 702, a rack 705 is fixed on the strip slider 703, a lower pressure block 706 is fixed to the top of the rack 705, and the lower pressure block 706 corresponds to the position of the upper pressure block 802, the transmission assembly 7 also includes an upper transmission shaft 707, a lower transmission shaft 708 and a vertical transmission shaft 709, one end of the upper transmission shaft 707 is rotatably connected to the side wall of the processing chamber 2, and the upper transmission shaft 707 passes through the first bearing seat 71 0 is installed on one side of the vertical rod 701, and a transmission gear 711 and a first bevel gear 712 are fixed at both ends of the upper transmission shaft 707, and the transmission gear 711 is meshed with the rack 705. The vertical transmission shaft 709 is installed on the inner wall of the processing chamber 2 through the second bearing seat 713. The second bevel gear 714 and the third bevel gear 715 are fixedly connected at both ends of the vertical transmission shaft 709, and the second bevel gear 714 is meshed with the first bevel gear 712. One end of the lower transmission shaft 708 is rotatably connected to the side wall of the housing 3, and the other end of the lower transmission shaft 708 is rotatably connected to the inner wall of the processing chamber 2. The fourth bevel gear 716 and the active bevel gear 717 are fixed at both ends of the lower transmission shaft 708, and the fourth bevel gear 716 is meshed with the third bevel gear 715, and the active bevel gear 717 is meshed with the driven bevel gear 611;

[0051] The upper transmission shaft 707 and the lower transmission shaft 708 are both arranged horizontally. When in use, the upper pressing block 802 gradually approaches the lower pressing block 706 as the fixing plate 801 moves downward. When the upper pressing block 802 contacts the lower pressing block 706, the lower pressing block 706 is pushed downward, thereby driving the rack 705 and the bar slider 703 to move downward along the vertical slide groove 702. When the bar slider 703 moves downward, the reset spring 704 is stretched. When the rack 705 moves downward, the transmission gear 711 is driven to rotate. When the transmission gear 711 rotates, the upper The transmission shaft 707 and the first bevel gear 712 rotate, and when the first bevel gear 712 rotates, it drives the second bevel gear 714 to rotate, and then drives the vertical transmission shaft 709 and the third bevel gear 715 to rotate. When the third bevel gear 715 rotates, it drives the fourth bevel gear 716 to rotate, and then drives the lower transmission shaft 708 and the active bevel gear 717 to rotate. When the active bevel gear 717 rotates, it drives the driven bevel gear 611 to rotate, and then drives the base shaft 610 to rotate, thereby driving the clutch assembly 6 to operate;

[0052] By setting the transmission component 7, the pressure feedback component 8 drives the transmission component 7 when in operation, and then drives the clutch component 6 to operate, which is beneficial to regulating the clutch of the driving force according to the pressure on the workpiece, so as to ensure that subsequent spinning work is carried out under the premise of safety.

[0053] Example 5, see Figure 6 , which is different from the above-mentioned embodiment, the edge of the fixing plate 801 is fixedly connected with a vertically arranged slide rail 11, one end of the upper pressing block 802 extends into the interior of the slide rail 11 and is slidably connected to the slide rail 11, a stud 12 is further provided inside the slide rail 11, and both ends of the stud 12 are rotatably connected to both ends of the slide rail 11 respectively, the stud 12 passes through the upper pressing block 802 and is threadedly connected to the upper pressing block 802, and one end of the stud 12 extends to the outside of the slide rail 11 and is fixedly connected with a bolt head 13;

[0054] When in use, the bolt head 13 can be rotated to drive the stud 12 to rotate, and the stud 12 drives the upper pressing block 802 to move along the slide rail 11 when rotating, thereby adjusting the initial height of the upper pressing block 802;

[0055] By setting the slide rail 11, the stud 12 and the bolt head 13, rotating the bolt head 13 can adjust the initial height of the upper pressure block 802, thereby changing the time point when the upper pressure block 802 contacts the lower pressure block 706, so that the pressure feedback component 8 drives the transmission component 7 and the clutch component 6 at different pressure values, which is conducive to adapting to the clamping pressure requirements of different workpieces and improving applicability.

[0056] Example 6, see Figure 6 and Figure 7 , which is different from the above embodiment, a limiting hole 14 is provided on the surface of the upper pressing block 802, a mounting block 15 is fixedly connected to the vertical rod 701, a cylinder 16 is fixed to the mounting block 15, a limiting pin 17 is fixed to the output shaft of the cylinder 16, a test gear 18 is fixedly connected to the movable seat 601, an angle steel 19 is fixed to the top wall of the housing 3, and a speed sensor 20 arranged toward the test gear 18 is fixed to the angle steel 19;

[0057] Among them, the speed sensor 20 is electrically connected to the cylinder 16, and the test gear 18 is driven to rotate when the movable seat 601 rotates. The speed sensor 20 monitors the speed of the test gear 18. When in use, when the upper pressure block 802 moves down, it drives the transmission component 7 to operate. When the transmission component 7 drives the clutch component 6 to be in a connected state, the limit hole 14 on the upper pressure block 802 is just opposite to the limit pin 17, and then the cylinder 16 is started. The cylinder 16 extends so that the limit pin 17 is inserted into the limit hole 14, thereby locking the upper pressure block 802. When the upper pressure block 802 is locked, the entire pressure feedback component 8 is locked, and the hydraulic cylinder 4 cannot control the pressure head 10 to move up. At the end of the spinning process, when the speed sensor 20 detects that the speed of the movable seat 601 is reduced to a safe range, the cylinder 16 is controlled to contract so that the limit pin 17 is separated from the limit hole 14, thereby releasing the locking effect of the pressure feedback component 8;

[0058] By setting the cylinder 16, the limit pin 17 and the limit hole 14, during the spinning operation, the limit pin 17 is inserted into the limit hole 14, thereby locking the pressure feedback component 8, and the hydraulic cylinder 4 cannot drive the pressure head 10 to move upward. Only when the speed sensor 20 detects that the speed of the movable seat 601 is reduced to a safe range, the cylinder 16 is controlled to release the lock of the pressure feedback component 8, which is beneficial to avoid the phenomenon of workpiece being thrown out due to accidental upward movement of the pressure head 10 during the spinning operation, thereby further improving safety.

[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
