Description

Technical Field

[0001] The present invention relates to the technical field of stamping equipment, and particularly to a high-speed feeding mechanism for a strip of an adaptive acoustic precision structural part. Background Art

[0002] In the production of acoustic precision structural parts in modern manufacturing, the strip feeding system is a mechanical device used to transfer materials from one processing stage to another in a stable, uniform, and efficient manner. A closed loop is formed by an inlet tension sensor and a speed sensor at the outlet position, and the servo motor adjusts the speeds of the feeding and traction rollers in real time to maintain a constant tension of the strip.

[0003] After retrieval, a Chinese utility model patent with a patent number of CN202420296126.7 and a patent name of an auxiliary feeding device for a stamping machine is disclosed in the prior art. It includes a bottom plate, a vertical plate, a first cylinder, a second cylinder, a feeding seat, a feeding clamping block, a stamping seat, a stamping block, and a feeding pressing block; the vertical plate is fixedly arranged on the bottom plate, the vertical plate is arranged in the vertical direction, the first cylinder is fixedly arranged on the bottom plate, the second cylinder is fixedly arranged on the vertical plate, the output end of the first cylinder moves in the horizontal direction, and the output end of the second cylinder moves in the vertical direction.

[0004] In the above solution, although the first cylinder is used to drive the feeding seat to move along the bottom plate, a feeding clamping block is arranged on the feeding seat to clamp the pipe fitting to be stamped for feeding, a guiding hole for the pipe fitting to be stamped to pass through is arranged on the vertical plate to prevent the pipe fitting to be stamped from shifting during transportation, a feeding pressing block is arranged at the lower part of the stamping block, a supporting hole is arranged in the feeding pressing block, and the pipe fitting to be stamped passing through the guiding hole passes through the supporting hole, and the feeding pressing block realizes the support and limit of the pipe fitting on the stamping side to prevent damage to the key part of the pipe fitting at the rear end that has not been stamped due to excessive impact during stamping.

[0005] However, in the high-speed production line of stamping equipment for processing acoustic precision structural parts, even if a constant tension of the strip is maintained during transportation. When the stamping equipment applies a downward stamping pressure, the strip will be subjected to a vertically downward force. If the stamping force is large, this pressure will increase the longitudinal tension of the strip, especially at the moment when the material is impacted, resulting in an instantaneous increase in tension. Furthermore, it causes uneven tension distribution of the strip, thereby triggering strip vibration and affecting the stability of feeding.

[0006] Therefore, a high-speed feeding mechanism for a strip of an adaptive acoustic precision structural part is proposed to solve the above-mentioned problems. Summary of the Invention

[0041] The present invention will be further described below in conjunction with embodiments.

[0042] Embodiment:

[0043] Please refer to the attached Figure 1-8 , this solution proposes a high-speed feeding mechanism for the adaptive acoustic precision structural part strip, which is installed on the workbench 1 provided with a stamping device 2. Specifically, it includes two groups of conveying rollers 3 installed on both sides of the workbench 1, and both ends of the strip are respectively arranged on the two groups of conveying rollers 3, and the conveying rollers 3 are driven based on a servo motor. When the two groups of conveying rollers 3 rotate synchronously, the strip can be conveyed through the stamping device 2 above the workbench 1, and further, when the strip passes through the stamping device 2, under the stamping work of the stamping device 2, acoustic precision structural parts are stamped on the strip. At the same time, a tension sensor 4 and a speed sensor 5 are respectively installed on both sides of the workbench 1, the tension sensor 4 is located at the conveying inlet of the strip, and the speed sensor 5 is located at the conveying outlet of the strip. Based on the detection data of the tension sensor 4 and the speed sensor 5, the servo motor can adjust the speed in real time to maintain a constant tension of the strip.

[0044] A tension assisting mechanism 6 is also installed on the workbench 1, and the tension assisting mechanism 6 is arranged in two groups on both sides of the stamping device 2; during the conveying process of the strip, the strip will first pass through a group of tension assisting mechanisms 6 and then enter the stamping device 2, and after passing through the stamping device 2, it will pass through a group of tension assisting mechanisms 6 again. When the strip is being stamped and processed in the stamping device 2, the stamping pressure will cause tension fluctuations of the strip. The tension assisting mechanism 6 converts the stamping pressure of the stamping device 2 into mechanical kinetic energy, and uses the mechanical kinetic energy to assist in adjusting the tension of the strip, so as to reduce the tension fluctuations of the strip and suppress the abnormal vibrations caused by the tension under the action of the punching force, thereby improving the stability of the processing and feeding processes and improving the blanking point accuracy.

[0045] Specifically, the tension assisting mechanism 6 includes a tension adjusting mechanism installed on the surface of the workbench 1, which is used to assist in adjusting the tension of the strip, so as to buffer the tension fluctuations generated instantaneously under the action of the punching force of the stamping device 2 when the strip is subjected to the punching force. The tension adjusting mechanism includes a guide rail frame A601 installed on the surface of the workbench 1, and a U-shaped frame 602 is slidably installed inside the guide rail frame A601. Two groups of tension wheels 603 are rotatably connected to the U-shaped frame 602. When the strip passes through the tension adjusting mechanism, the strip passes between the two groups of tension wheels 603. At the same time, a connecting plate 604 is also connected to the surface of the U-shaped frame 602, and the other end of the connecting plate 604 is connected to the punch head of the stamping device 2. After the strip enters the stamping device 2 and the stamping device 2 starts to work, the punch head moves downward and applies pressure to the strip for stamping, and the strip will receive a vertically downward force. The downward pressure of the punch head will apply a greater longitudinal tension to the strip, especially when the strip is under the load of the stamping die. At this time, the vibration caused by stamping will spread in the strip and the feeding system, resulting in uneven tension distribution of the strip. And during the reset process of the punch head, it will also cause the tension of the strip to decrease, thereby causing short-term fluctuations in the tension of the strip. By connecting the stamping device 2 and the tension adjusting mechanism through the connecting plate 604, when the punch head moves downward, the kinetic energy of the punch head is synchronously converted into the kinetic energy for driving the U-shaped frame 602 to slide downward on the guide rail frame A601. Further realizing the buffering of the punching force, smoothing the impact force of the punch head on the strip, reducing the instantaneous load on the strip, and contributing to improving the stability of the entire strip and the feeding mechanism.

[0046] Meanwhile, a piston cylinder A605 is also installed inside the guide rail frame A601. A piston rod A606 is connected inside the piston cylinder A605 through a piston block, and the upper end of the piston rod A606 is connected to the lower surface of the U-shaped frame 602. Meanwhile, a spring A607 is sleeved on the surface of the piston rod A606. One end of the spring A607 is connected to the surface of the piston cylinder A605, and the other end of the spring A607 is connected to the surface of the U-shaped frame 602. When the connecting plate 604 synchronously applies the kinetic energy of the stamping head to the U-shaped frame 602, the U-shaped frame 602 presses down the piston rod A606 to slide into the piston cylinder A605, and the gas in the piston cylinder A605 is compressed, further realizing the conversion of the kinetic energy of the downward sliding of the U-shaped frame 602 into the internal energy in the piston cylinder A605. Meanwhile, during the process of the U-shaped frame 602 sliding down inside the guide rail frame A601, the U-shaped frame 602 will compress the spring A607, and further buffer the sliding amplitude of the U-shaped frame 602 through the elastic force of the spring A607, realizing the buffering of the punching force of the stamping head and further smoothing the punching force of the impact head.

[0047] It should be noted that deviation rectifying mechanisms are installed on both sides of the tension adjusting mechanism. When the strip is stamped in the stamping equipment 2, due to the uneven longitudinal and transverse tensions of the strip, deviation may also occur. The longitudinal tension refers to the pulling force along the moving direction of the strip, while the transverse tension is the pulling force perpendicular to the moving direction of the strip. Before stamping starts, the strip is in an initial tension state; during stamping, the conveying roller 3 applies longitudinal tension to traction the strip; as a result, the force borne by one side of the strip is greater than that of the other side, thereby causing the strip to deviate. Based on the deviation rectifying mechanism, the deviation degree of the strip can be restricted, and the strip can be pushed back from the deviation side to the center, maintaining the stability of the strip on the feeding mechanism.

[0048] The deviation rectifying mechanism includes a guide rail frame B608 installed on the workbench 1. A slider 609 is slidably installed inside the guide rail frame B608, and two groups of guide wheels 611 are rotatably connected to the slider 609. When the strip passes through the deviation rectifying mechanism, the strip will pass between the two groups of guide wheels 611, thereby realizing the guiding and conveying of the strip. A piston cylinder B612 is also installed inside the guide rail frame B608. A piston rod B613 is connected inside the piston cylinder B612 through a piston block, and the upper end of the piston rod B613 is connected to the lower surface of the slider 609. The lower ends of the two piston cylinders B612 are both connected to an air pipe 614, and at the same time the air pipe 614 is connected to the piston cylinder A605 through a connecting pipe 615. When the tension adjusting mechanism converts the kinetic energy of the punching head of the punching equipment 2, it will convert the kinetic energy into the internal energy in the interconnected space inside the piston cylinder A605, the connecting pipe 615, and the air pipe 614. Further, after the deviation rectifying driving mechanism installed on the deviation rectifying mechanism detects the deviation direction of the strip, it will convert the stored internal energy into the kinetic energy for driving the slider 609 on the deviation side to slide upward, and adjust the installation angles of the two groups of guide wheels 611 on the deviation rectifying mechanism. The two groups of guide wheels 611 are inclinedly distributed between the two groups of sliders 609, and the higher side of the guide wheel 611 is the side where the strip deviates. That is, when the strip deviates under the influence of punching, it will deviate to the higher side of the guide wheel 611. During this process, the deviation edge of the strip contacts the higher side of the guide wheel 611 and generates a frictional force. Since the direction of the frictional force is always opposite to the relative movement between the contact surfaces, there will be two components in the direction of the frictional force when the deviation edge of the strip contacts the guide wheel 611. The horizontal component of the frictional force will face the center of the strip, generating an inward horizontal thrust. This inward horizontal thrust prompts the strip to move back to the center position from the deviation edge, overcomes the tendency of deviation, re-guides the strip, and thereby realizes the deviation correction of the strip.

[0049] It should be noted that a mounting plate 620 is installed between the two guide rail frames B608 in the deviation rectifying mechanism. Two deviation rectifying driving mechanisms are installed on the surface of the mounting plate 620. When the strip is conveyed above the mounting plate 620, the strip will pass between the two deviation rectifying driving mechanisms. Thereby, it can be ensured that no matter which side the strip deviates in the horizontal direction, it will be detected, and then the slider 609 on the deviation side will be driven to rise, and the inclination angle of the guide wheel 611 will be adaptively adjusted.

[0050] Two sets of convex rings 616 are connected to the inner wall of the air pipe 614. Sealing columns 618 are connected to the two sets of convex rings 616 through springs B617. The pulling directions of the two springs B617 on the sealing columns 618 are opposite. Further, when the sealing columns 618 are not affected by external forces, they will slide to the connection between the air pipe 614 and the piston cylinder B612 under the elastic force of the springs B617, so as to seal and block the inside of the piston cylinder B612 with the sealing columns 618. At this time, when the piston rod A606 squeezes the gas in the piston cylinder A605, the air pressure is less than the elastic force of the spring B617 and cannot push the sealing column 618 to slide, so that the gas is gradually compressed and converted into internal energy. At the same time, electromagnets 619 are installed at both ends of the air pipe 614. When the deviation driving mechanism detects the deviation direction of the material belt, it will synchronously turn on the electromagnet 619 on the same side to operate. After the electromagnet 619 is powered on, it will generate a magnetic force and adsorb the sealing column 618 to slide towards the electromagnet 619 side against the elastic force of the spring B617. During the sliding process of the sealing column 618, the blockage of the piston cylinder B612 on the same side will be gradually released, so that the internal energy stored in the air pipe 614 is released, and the gas in the air pipe 614 will enter the piston cylinder B612, pushing the piston block in the piston cylinder B612 to slide upward; realizing the upward sliding of the piston rod B613 to push the slider 609 on the guide rail frame B608; controlling the rise of the slider 609 on the offset side of the material belt; and finally realizing the adjustment of the inclination angle of the guide wheel 611.

[0051] The slider 609 is set in an F shape, and two sets of rotating plates 610 are rotatably connected to the upper end. Two sets of guide wheels 611 are respectively rotatably connected to the two sets of rotating plates 610, and the rotation connection directions are vertically distributed. Thus, when the slider 609 slides to adjust the height of one side of the guide wheel 611, the two sets of guide wheels 611 can always be controlled to be parallel.

[0052] In contrast, the deviation rectifying mechanism includes a vertical rod 621 connected to the surface of the mounting plate 620. A rotating plate 622 is rotatably connected to the surface of the vertical rod 621. The rotating plate 622 is mounted on the vertical rod 621 through a torsion spring, and the torsion spring always controls the rotating plate 622 to rotate towards the tape side, so that the other end of the rotating plate 622 abuts against the surface of the tape. When the tape deviates, it will push the rotating plate 622 on the deviation side to rotate on the vertical rod 621 against the elastic force of the torsion spring. A conductive rod 625 is connected to the surface of the rotating plate 622, and the conductive rod 625 is electrically connected to a battery 627 on the mounting plate 620 through a wire A626. A conductive sheet 628 is provided on the surface of the mounting plate 620 along the rotation trajectory of the conductive rod 625, and the conductive sheet 628 is electrically connected to the electromagnet 619 on the same side through a wire B629. When the rotating plate 622 rotates under the thrust of the tape deviation, it will drive the conductive rod 625 to rotate, further causing the conductive rod 625 to abut against the surface of the conductive sheet 628. When the conductive rod 625 and the conductive sheet 628 are in contact, the circuit will be connected, that is, the power of the battery 627 will pass through the wire A626, the conductive rod 625, the conductive sheet 628, and the wire B629 to the electromagnet 619 in sequence, thereby realizing the energization of the electromagnet 619 to control the slider 609 on the deviation side of the tape to rise, and further correcting the deviation of the tape.

[0053] A limiting block 630 is also rotatably connected to the surface of the vertical rod 621, and the rotation has a damping effect, which is used to control the movement of the rotating plate 622 within a predetermined range to prevent damage caused by exceeding the design range; by adjusting the position of the limiting block 630, the rotation angle of the rotating plate 622 can be limited, so that the rotating plate 622 can rotate to one side of the tape under the action of the torsion spring and not contact the tape, avoiding interference with the conveyance of the tape. A side stop block 624 is hinged and installed on the side of the rotating plate 622 close to the tape through a damping shaft 623. The side stop block 624 can increase the height of the detection of the tape deviation. At the same time, combined with the adjustment of the rotation angle of the rotating plate 622, the deviation rectifying drive mechanism can be applied to tapes of different widths and thicknesses, improving the practicability of the device. At the same time, the installation angle of the side stop block 624 on the rotating plate 622 can be adjusted through the damping shaft 623, so that the side stop block 624 can always be parallel to the tape, further increasing the applicability of the device.
