Description

TECHNICAL FIELD

[0001] The utility model relates to metal processing equipment technical field, especially a straightening machine for positive and negative. BACKGROUND

[0002] Straightening machine is a kind of mechanical equipment for straightening and flattening treatment to metal plate, strip or wire material. Straightening machine applies appropriate pressure and bending stress through a series of straightening rollers, so that the defects such as bending and warping of material surface can be corrected, thereby obtaining higher flatness material. Straightening machine is widely used in plate factory, aluminum profile processing factory, automobile production, household appliance manufacturing and other fields.

[0003] Finished steel plate is usually coiled and packed into roll shape to facilitate transportation and reduce cost. When the uncoiler releases the steel coil, different feeding methods will make the plate present different bending directions. When discharging from the upper part of the uncoiler, the plate is concave downward, and when discharging from the lower part of the uncoiler, the plate is convex upward. Therefore, it is necessary to use a straightening machine to straighten the uncoiled plate and eliminate internal stress. Because the appearance defects of multiple groups of uncoiled plates in the same batch are different and the bending directions are opposite, only using one straightening machine cannot achieve effective correction and cannot completely eliminate the internal stress of the plate.

[0004] From the above prior art, it can be known that because the appearance defects are different and the bending directions are opposite, the existing straightening machine cannot completely eliminate the internal stress when correcting the uncoiled plate, and cannot meet the demand of high-standard straightening processing.

[0044] The utility model will be described in detail below with reference to the drawings and in combination with the embodiments. Figure 1 to the drawings and in combination with the embodiments. Figure 5 The utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0045] The embodiment relates to a positive and negative universal leveling machine, which can adapt to different uncoiling modes of plate materials, and has the advantages of complete stress elimination effect and good leveling effect.

[0046] Overall structure, refer to Figure 1 The positive and negative universal leveling machine comprises a rack 1, a lower roller assembly 2, an upper roller assembly 3, a feeding assembly 4 and an adjusting assembly 5. The rack 1 is fixedly arranged on the horizontal ground, and the lower roller assembly 2 and the upper roller assembly 3 are both mounted on the rack 1. The lower roller assembly 2 is located at the bottom of the rack 1, and the upper roller assembly 3 is located above the lower roller assembly 2. The lower roller assembly 2 is connected with a driving device, for example, connected with a driving motor in a chain transmission mode. The lower roller assembly 2 can rotate under the action of the driving device. The upper roller assembly 3 and the lower roller assembly 2 jointly form a continuous wave-shaped roller gap with adjustable width. The feeding assembly 4 is slidingly arranged on one end of the rack 1 along the vertical direction. When the feeding assembly 4 slides to a specific position, it can be engaged with the lower roller assembly 2, so as to rotate synchronously with the lower roller assembly 2. The adjusting assembly 5 is slidingly arranged on the other end of the rack 1 away from the feeding assembly 4 along the vertical direction, and the adjusting assembly 5 can be adjusted to a position with the same height as the upper roller assembly 3.

[0047] The continuous wave-shaped roller gap formed by the lower roller assembly 2 and the upper roller assembly 3 on the rack 1 can bend and correct the bent plate passing through the roller gap, thereby improving the shape defects of the plate and eliminating the internal stress of the plate. The sliding structure of the upper roller assembly 3 enables the width of the continuous wave-shaped roller gap to be adjusted according to the thickness of the plate, further optimizing the flattening and internal stress relief effect. The feeding assembly 4 can be adjusted to engage with the lower roller assembly 2, and synchronously rotate in the opposite direction to realize feeding by friction engagement, and send the plate into the equipment. The adjusting assembly 5 can be adjusted to the same height as the upper roller assembly 3, thereby cooperating with the upper roller assembly 3 to flatten the plate, so that the shape defect correction and internal stress relief effect of the plate using the upper feeding mode are better. The adjusting assembly 5 can also be slid upward to adjust to a position not in contact with the plate, so that the shape defect correction and internal stress relief effect of the plate using the lower feeding mode are better.

[0048] With reference to Figure 1 and Figure 2 The lower roller assembly 2 includes a lower limiting plate 201, a lower flattening roller 202, and a synchronous wheel 203. The number of lower limiting plates 201 is two. The two lower limiting plates 201 are arranged in parallel along the direction perpendicular to the ground. A plurality of lower flattening rollers 202 are connected in a vertical rotating manner between the two lower limiting plates 201 along the horizontal direction. The plurality of lower flattening rollers 202 are arranged along the direction perpendicular to the plate conveying. A plurality of synchronous wheels 203 are rotatably arranged on the lower limiting plate 201. One end of the lower flattening roller 202 is sleeved with a gear. The synchronous wheel 203 is installed between and engaged with two adjacent lower flattening rollers 202, so that the plurality of lower flattening rollers 202 can synchronously rotate in the same direction.

[0049] By setting the lower roller assembly 2 as the lower limiting plate 201, the lower flattening roller 202, and the synchronous wheel 203, the lower limiting plate 201 supports and limits the installation of the lower flattening roller 202 and the synchronous wheel 203. The lower flattening roller 202 can synchronously rotate in the same direction through the transmission structure of the synchronous wheel 203 engagement, drive the plate to move along the roller surface, and thus complete the flattening.

[0050] With reference to Figure 1 and Figure 3The upper roller assembly 3 comprises an upper limiting plate 301, an upper leveling roller 302 and a first lifting machine 303. The number of the upper limiting plate 301 is two. The two upper limiting plates 301 are arranged in parallel along the direction perpendicular to the ground. The plurality of upper leveling rollers 302 are vertically connected between the two upper limiting plates 301 along the horizontal direction. The plurality of upper leveling rollers 302 are arranged in a staggered manner with the plurality of lower leveling rollers 202 in the vertical direction, thereby forming a continuous wavy roller gap. The first lifting machine 303 is installed on the rack 1. The telescopic end of the first lifting machine 303 is arranged on the rack 1 and is fixedly connected with the upper limiting plate 301. The first lifting machine 303 can change the width of the roller gap between the upper leveling roller 302 and the lower leveling roller 202 by driving the upper limiting plate 301 to slide relative to the rack 1. The number of the first lifting machine 303 can be set to multiple groups. The first lifting machine 303 can adopt a worm screw lifting machine. The synchronous transmission structure can be adopted between the two first lifting machines 303 on the opposite sides to ensure the stability of the lifting process.

[0051] By setting the upper roller assembly 3 as the structure of the upper limiting plate 301, the upper leveling roller 302 and the first lifting machine 303, the upper limiting plate 301 plays a limiting role in the installation of the upper leveling roller 302, and the first lifting machine 303 can change the width of the roller gap between the upper leveling roller 302 and the lower leveling roller 202, thereby adapting to different plate thicknesses.

[0052] It should be noted that the shape of the roller gap formed between the upper roller assembly 3 and the lower roller assembly 2 in the embodiment can also be adaptively adjusted to other shapes such as a wedge shape according to the shape, material, structure and other characteristics of the plate to be leveled, so as to achieve better shape correction, roller mark and internal stress elimination effects.

[0053] Referring to Figure 1 and Figure 4 The feeding assembly 4 comprises a cylinder 401, a feeding limiting plate 402 and a feeding roller 403. The number of the feeding limiting plate 402 is two.

The telescopic ends of the two cylinders 401 are arranged on the rack 1 and are fixedly connected with the two feeding limiting plates 402, respectively, and can drive the feeding limiting plate 402 to slide along the vertical direction. One end of the feeding limiting plate 402 is clamped with the upper limiting plate 301, and a sliding connection structure in the vertical direction is formed between the feeding limiting plate 402 and the upper limiting plate 301. This structure can further improve the smoothness and stability of the feeding roller 403 during the vertical sliding process.

[0054] By setting the feeding assembly 4 as the structure of the air cylinder 401, the feeding limiting plate 402 and the feeding roller 403, the feeding limiting plate 402 provides a limit for the installation and movement of the feeding roller 403. The air cylinder 401 can move the feeding roller 403 to a position capable of engaging with the lower leveling roller 202 by driving the feeding limiting plate 402, so that the feeding roller 403 can rotate reversely synchronously with the lower leveling roller 202, thereby realizing the engagement and feeding of the plate. The air cylinder 401 has a faster response speed in the driving mode.

[0055] With reference to Figure 1 and Figure 5 , the adjusting assembly 5 includes the second elevator 501, the adjusting limiting plate 502 and the adjusting roller 503.

The adjusting roller 503 can be adjusted to the height equal to that of the upper leveling roller 302, thereby cooperating with the upper leveling roller 302 and the lower leveling roller 202 to perform the leveling work. The adjusting roller 503 can also be adjusted to be above the upper leveling roller 302, at which time the adjusting roller 503 does not participate in the leveling work. The adjusting roller 503 can be adjusted to different positions according to different uncoiling modes of the plate. The number of the second elevators 501 can be two. The two second elevators 501 are respectively located on the two sides of the rack 1. The synchronous transmission rod 504 is connected between the two second elevators 501.
