Description

Technical Field

[0001] The invention relates to the technical field of curved surface forming of medium and thick plates, and in particular to a curved surface forming device for medium and thick plates and a processing method thereof. Background Art

[0002] A type of plate commonly used in engineering whose thickness is much smaller than the plane size, steel plates with a thickness of 4.5mm to 25mm are called medium and thick plates. Although the thickness is small, the deformation caused by the transverse shear force and the bending deformation are of the same order of magnitude. When analyzing the stress and deformation under static load, the transverse shear effect must still be considered, and the normal stress perpendicular to the plate surface can be ignored; when analyzing the stress and deformation under dynamic load, in addition to considering the transverse shear effect, the inertia force and damping moment of the micro-segment must also be considered; medium and thick plates have long been widely used in the machinery industry, and stamping devices are required for the curved surface forming of medium and thick plates.

[0003] During use, the existing medium and thick plate curved surface forming stamping device drives the punch head through the press machine to press the medium and thick plate in a high-temperature state into the stamping die. The curved surface part is formed by hot stamping due to the action of external force, and the pressure at the intersection of the bending point and the flat part is limited, and it cannot be completely formed in a short time. This will cause the bending point of the medium and thick plate to be warped after the curved surface is removed, which will cause the angle between the flat part and the curved surface part to be greater than the specified angle, resulting in failure of the curved surface forming of the medium and thick plate, thereby reducing the use value of the curved surface forming stamping device. Summary of the invention

[0004] The present invention discloses a curved surface forming device for medium and thick plates, aiming to solve the technical problem that in the existing curved surface forming stamping device for medium and thick plates, during use, a press machine drives a punch head to press the medium and thick plates in a high-temperature state into a stamping die, and the curved surface part is formed by hot stamping due to the action of external force, and the pressure at the intersection of the bending point and the plane part is limited, and it cannot be completely formed in a short time, which will cause the bending point of the curved surface of the medium and thick plate to be tilted upward after the curved surface is removed, which will cause the angle between the plane part and the curved surface part to be greater than the specified angle, resulting in the failure of the curved surface forming of the medium and thick plate.

During the downward pressing process of the lower pressure frame, the axis frame shifts toward both ends, so that each movable pressure roller gradually contacts and squeezes the two ends of the bending point of the medium and thick plate. Continuous pressing makes the two ends of the bending point of the medium and thick plate gradually parallel to the bending part of the medium and thick plate.

[0018] A method for forming a curved surface of a medium-thick plate, using a medium-thick plate curved surface forming device as described above, comprises the following steps:

[0019] Step 1: Place the medium and thick plate in a high temperature state under the two limit pressing plates, so that it passes between the punch head and the forming die, and then adjust the hydraulic cylinder 1 to drive the limit pressing plate to press down, so that the guide roller contacts the upper surface of the medium and thick plate, and then start the press, which drives the punch head to perform punching operation on the medium and thick plate;

[0020] Step 2: After the stamping is completed, the driving motor is started, and the driving motor drives each impact ball to impact the triangular oscillation frame. The elastic connecting rod is stretched during the rotation of the impact ball, and the impact ball first impacts the oscillation contact groove at the bottom of the triangular oscillation frame. The initial impact oscillation effect is the largest. As the impact ball rotates, it impacts different oscillation contact grooves at different times. The oscillation frequency generated by each impact gradually decreases, thereby performing oscillation shaping of different frequencies on the bending point. During the impact shaping process, the hydraulic cylinder 2 is adjusted to drive the lower pressure frame to reciprocate and rise and fall. During the downward pressure of the lower pressure frame, the shaft frame shifts toward both ends, so that each movable pressure roller gradually contacts and squeezes the two ends of the bending point of the medium and thick plate. Continuous pressing makes the two ends of the bending point of the medium and thick plate gradually parallel to the bending point of the medium and thick plate, and the effect of the bending point processing component after processing is further expanded by extending the pressing method;

[0021] Step three: After the bending point processing component and the extension processing component have worked for a period of time, both stop working and start the water pump. The water pump transports water to the water spray arc plate, sprays the water through the water spray holes, and then passes through the perforations on the processing table and the forming mold to contact the lower surface of the medium and thick plate. After the two are in contact, the water quickly takes away the heat carried by the medium and thick plate, accelerating the cooling of the medium and thick plate surface. During the water cooling process, start the air compressor, which compresses the gas inside the sealing frame and transports it to the compressed gas spray plate, and sprays it through the air jet holes. On the one hand, this part of the sprayed gas accelerates the flow impact of the water, and on the other hand, the gas impacts the surface of the formed medium and thick plate, causing it to quickly separate from the forming mold. After the medium and thick plate separates from the forming mold, it is collected to end the operation.

[0022] From the above, it can be seen that the medium and thick plate curved surface forming device provided by the present invention has the function of starting the driving motor after the punch head is driven by a press to punch the medium and thick plate into the inside of the forming mold, and the driving motor drives each impact ball to impact the triangular oscillation frame. The elastic connecting rod is stretched during the rotation of the impact ball, and the impact ball first hits the oscillation contact groove at the bottom of the triangular oscillation frame. The initial impact oscillation effect is the largest. As the impact ball rotates, it hits different oscillation contact grooves at different times. The oscillation frequency generated by each impact gradually decreases, thereby performing oscillation shaping of the bending point with different frequencies, so that the internal structure at the bending point of the medium and thick plate is stabilized faster, ensuring that after the curved surface of the medium and thick plate is formed, there will be no rebound and warping at the bending point.

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] A medium and thick plate curved surface forming device disclosed in the present invention is mainly applied to the existing medium and thick plate curved surface forming stamping device. During use, the punching head is driven by a press machine to press the medium and thick plate in a high-temperature state into a stamping die. The curved surface part is formed by hot stamping due to the action of external force, and the pressure at the intersection of the bending point and the plane part is limited, and it cannot be completely formed in a short time. This will cause the bending point of the medium and thick plate to be tilted upward after the curved surface is removed, which will cause the angle between the plane part and the curved surface part to be greater than the specified angle, resulting in the failure of the curved surface forming of the medium and thick plate.

[0036] Reference Figure 1-Figure 10 A medium and thick plate curved surface forming device comprises a processing table 1 and two limiting pressing plates 22, a groove is formed on the top of the processing table 1, and a forming mold 4 is fixedly connected inside the groove, and a through hole 6 is formed at the position where the forming mold 4 and the processing table 1 are connected, and the two limiting pressing plates 22 are provided with a bending point processing component 20 near the top of the forming mold 4, and the bending point processing component 20 comprises a moving slide 2007, a matching oscillation plate 2001 is fixedly connected to one side of the moving slide 2007, and a triangular oscillation frame 2006 is fixedly connected to the top of the matching oscillation plate 2001, and the inclined surface of the triangular oscillation frame 2006 is equidistant. An oscillation contact groove 2005 is provided, and a mounting rod 2008 is fixedly connected to the top of the movable slide 2007, and one end of the mounting rod 2008 is fixedly connected to a motor frame 2009, and a driving motor 2010 is fixedly connected inside the motor frame 2009, and the output shaft of the driving motor 2010 is fixedly connected to a driving shaft 2002 through a coupling, and the driving shaft 2002 is located on the outer wall above the triangular oscillation frame 2006 and is fixedly connected to a fixed ring sleeve 2012, and the outer wall of the fixed ring sleeve 2012 is annularly distributed with elastic connecting rods 2004, and one end of each elastic connecting rod 2004 is fixedly connected to an impact ball 2003.

[0037] In a specific application scenario, after the punch head 10 is driven by the press machine 9 to punch the medium and thick plate into the forming mold 4, the drive motor 2010 is started, and the drive motor 2010 drives each impact ball 2003 to impact the triangular oscillation frame 2006. The elastic connecting rod 2004 is stretched during the rotation of the impact ball 2003, and the impact ball 2003 first impacts the oscillation contact groove 2005 at the bottom of the triangular oscillation frame 2006. The initial impact oscillation effect is the largest. As the impact ball 2003 rotates, it impacts different oscillation contact grooves 2005 at different times. The oscillation frequency generated by each impact gradually decreases, thereby performing oscillation shaping of the bending point with different frequencies, so that the internal structure at the bending point of the medium and thick plate is stabilized faster, ensuring that after the curved surface of the medium and thick plate is formed, there will be no rebound and warping at the bending point, thereby improving the curved surface forming effect of the medium and thick plate. During the curved surface forming process of the medium and thick plate, the oscillation plate 2001 is in contact with the curved surface of the medium and thick plate.

[0038] Specifically, in the present invention, rapid shaping of the bending points of medium and thick plates is achieved through continuously decreasing impact shocks, thereby avoiding damage and fracture of the internal structure of the bending points caused by high-intensity shocks. The shocks from high to low ensure accelerated shaping while reducing damage to the internal structure of the bending points, thereby protecting the medium and thick plates.

[0039] It should be noted that when the elastic connecting rod 2004 is passively stretched and rotated, its middle position is limited by the limiting ring sleeve 2013 to ensure that it can hit the triangular oscillation frame 2006 during the rotation process, avoiding its position deviation and causing the oscillation effect to fail to occur.

[0043] It should be noted that when the medium and thick plate is fixed, the hydraulic cylinder 3 25 drives the side positioning plates 13 to clamp the two sides of the medium and thick plate to improve its stability during the stamping process.

[0044] Reference Figure 1 , Figure 6 , Figure 7 and Figure 8 In a preferred embodiment, the limiting pressure plate 22 is provided with an installation groove 23 near the top of the movable guide rail 16, and an extension processing component 24 is provided inside the installation groove 23, and the extension processing component 24 includes a lower pressure frame 2401, and the limiting pressure plate 22 is fixedly connected to a connecting frame 2402 at an equal distance on the top of the installation groove 23, and each connecting frame 2402 is fixedly connected to a hydraulic cylinder 2403 on the side facing downward, and the output ends of multiple hydraulic cylinders 2403 are fixedly connected to the top of the lower pressure frame 2401, and the bottom ends of the lower pressure frame 2401 are connected to an axis frame 2404 through hinges, and the interiors of the two axis frames 2404 are evenly connected to movable pressure rollers 2405 through bearings, and both sides of the lower pressure frame 2401 are fixedly connected to rear abutment plates 2406, and the two rear abutment plates 2406 are evenly fixedly connected to extrusion spring rods 2407 on the side facing the axis frame 2404, and one end of the extrusion spring rod 2407 is fixedly connected to the outer wall of the axis frame 2404.

[0045] Specifically, during the operation of the bending point processing component 20, the hydraulic cylinder 2403 is adjusted to drive the lower pressure frame 2401 to move up and down. During the downward pressure of the lower pressure frame 2401, the shaft frame 2404 is offset toward both ends, so that each movable pressure roller 2405 gradually contacts and squeezes the two ends of the bending point of the medium and thick plate. Continuous pressing makes the two ends of the bending point of the medium and thick plate gradually parallel to the bending part of the medium and thick plate. The effect of the bending point processing component 20 after processing is further expanded by extending and pressing, and the stability of the medium and thick plate curved surface after forming is further improved.

[0046] Reference Figure 1 , Figure 2 , Fig. 9 and Fig.10 In a preferred embodiment, the bottom of the processing table 1 located below the forming mold 4 is fixedly connected to a sealing frame 5, and both sides of the sealing frame 5 are fixedly connected to limiting slide rails 21, and the two limiting slide rails 21 are provided with the same water cooling component 26, and the water cooling component 26 includes a water spray arc plate 2601, and the outer side wall of the water spray arc plate 2601 facing downward is fixedly connected to a sliding frame 2602, and the sliding frame 2602 is slidably connected to the inside of the two limiting slide rails 21, and the inner wall of the sealing frame 5 on one side close to the two limiting slide rails 21 is fixedly connected to a cylinder 27, and the output end of the cylinder 27 is fixedly connected to one side of the sliding frame 2602.

[0047] Reference Fig. 9 and Fig.10 In a preferred embodiment, a pump ring frame 2611 is fixedly connected to the other side of the sliding frame 2602, and a water pump 2607 is fixedly connected to the inside of the pump ring frame 2611. The water delivery end of the water pump 2607 is connected to the inside of the water spray arc plate 2601 through a pipeline. The outer side wall of the water spray arc plate 2601 facing upward is provided with a water spray hole 2608. The water inlet end of the water pump 2607 is fixedly connected to a diversion pipe 2610. The diversion pipe 2610 has two diversion holes, and a telescopic water inlet pipe 2603 is fixedly connected to the inside of one of the diversion holes. The water inlet end of the telescopic water inlet pipe 2603 is located on the outside of the sealing frame 5, and the water inlet end of the other diversion hole is located on the outside of the sealing frame 5. A circulation pipe 2612 is fixedly connected to the inside of each diversion hole, and a water suction nozzle 2613 is fixedly connected to the bottom of the circulation pipe 2612. The water suction nozzle 2613 is close to the bottom of the sealing frame 5. The outer walls of the sliding frame 2602 close to both ends are fixedly connected to compressed gas spray plates 2604, and the outer walls of the compressed gas spray plates 2604 facing obliquely upward are provided with jet holes 2609. The bottom of the compressed gas spray plate 2604 is fixedly connected to an organic ring frame 2606, and the inside of the organic ring frame 2606 is fixedly connected to an air compressor 2605, and the gas delivery end of the air compressor 2605 is connected to the inside of the compressed gas spray plate 2604 through a pipeline.

[0048] Specifically, after the curved surface of the medium and thick plate is formed, the water pump 2607 is started, and the water pump 2607 transports water to the water spray arc plate 2601, and the water is sprayed out through the water spray hole 2608, and then passes through the processing table 1 and the perforation 6 on the forming mold 4 to contact the lower side of the curved surface of the medium and thick plate. After the two are in contact, the water quickly takes away the heat carried by the medium and thick plate, accelerates the cooling of the curved surface of the medium and thick plate, and accelerates its shaping.

[0049] It should be noted that, during the water cooling process, after the water comes into contact with the curved surface of the medium and thick plate in a high temperature state, the water absorbs heat and vaporizes, and the air pressure inside the sealing frame 5 gradually rises, and the air compressor 2605 is started. The air compressor 2605 compresses the gas inside the sealing frame 5 and transports it to the compressed gas spray plate 2604, and sprays it out through the jet hole 2609. On the one hand, this part of the sprayed gas accelerates the flow impact of the water body, and on the other hand, the gas impacts the curved surface of the medium and thick plate after molding, so that it quickly separates from the molding mold 4, thereby preventing the curved surface of the medium and thick plate from sticking to the molding mold 4 and being unable to desulfurize.

[0050] In a specific application scenario, when water is sprayed onto the curved surface of the medium and thick plate through the water spray hole 2608, part of the water absorbs less heat and cannot be vaporized, and this part of the water falls into the sealing frame 5. During operation, the water pump 2607 absorbs this part of the water through the water suction nozzle 2613 on the circulation pipe 2612, and recycles it to reduce water loss.

[0051] A method for forming a curved surface of a medium-thick plate, using a medium-thick plate curved surface forming device as described above, comprises the following steps:

[0052] Step 1: Place the medium and thick plate in a high temperature state under the two limiting pressure plates 22, so that it passes between the punch head 10 and the forming die 4, and then adjust the hydraulic cylinder 15 to drive the limiting pressure plate 22 to press down, so that the guide roller 17 contacts the upper surface of the medium and thick plate, and then start the press machine 9, which drives the punch head 10 to perform a punching operation on the medium and thick plate;

[0053] Step 2: After the stamping is completed, the driving motor 2010 is started. The driving motor 2010 drives each impact ball 2003 to impact the triangular oscillation frame 2006. The elastic connecting rod 2004 is stretched during the rotation of the impact ball 2003, and the impact ball 2003 first impacts the oscillation contact groove 2005 at the bottom of the triangular oscillation frame 2006. The initial impact oscillation effect is the largest. As the impact ball 2003 rotates, it impacts different oscillation contact grooves 2005 at different times, and the oscillation frequency generated by each impact is The rate is gradually reduced, so that the bending point is subjected to oscillation shaping of different frequencies. During the impact shaping process, the hydraulic cylinder 2403 is adjusted to drive the lower pressing frame 2401 to rise and fall back and forth. During the downward pressing process of the lower pressing frame 2401, the shaft frame 2404 is offset toward both ends, so that each movable pressing roller 2405 gradually contacts and squeezes the two ends of the bending point of the medium and thick plate. Continuous pressing makes the two ends of the bending point of the medium and thick plate gradually parallel to the bending part of the medium and thick plate, and the effect of the bending point processing component 20 after processing is further expanded by extending and pressing.

[0054] Step three: After the bending point processing component 20 and the extension processing component 24 have worked for a period of time, both stop working and start the water pump 2607. The water pump 2607 transports water to the water spray arc plate 2601, sprays the water through the water spray hole 2608, and then passes through the perforations 6 on the processing table 1 and the forming mold 4 to contact the lower surface of the medium and thick plate. After the two contact, the water quickly takes away the heat carried by the medium and thick plate, accelerating the cooling of the medium and thick plate surface. During the water cooling process, start the air compressor 2605. The air compressor 2605 compresses the gas inside the sealing frame 5 and transports it to the compressed gas spray plate 2604, and sprays it through the jet hole 2609. On the one hand, this part of the sprayed gas accelerates the flow impact of the water, and on the other hand, the gas impacts the curved surface of the formed medium and thick plate, causing it to quickly separate from the forming mold 4. After the medium and thick plate separates from the forming mold 4, it is collected to end the operation.
