Description

Technical Field

[0002] Background information Thin-walled steel structure is a structure made of steel strips that are cold-bent into steel strips of various cross-sections. During the production process, after a roll of steel strip is used up, it is necessary to replace the steel strip to continue production, and the head and tail of the old and new steel strips need to be connected. On the one hand, it can avoid re-debugging the equipment, and on the other hand, it can reduce the waste of surplus materials. Before connecting the new and old steel strips, the irregular parts of the head and tail need to be flattened and then cut off, so that the new and old steel strips can be better welded together; the existing new steel strip head and the old steel strip tail are usually cut separately during cutting. If the cutting device deviates during cutting, it is easy to cause the incisions of the new and old steel strips to not fit perfectly, which will increase the difficulty of welding, reduce the interface strength, and affect the subsequent processing quality of the steel strip.

DETAILED DESCRIPTION

[0015] 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. See also Figure 1-Figure 7 The present invention provides a technical solution: a leveling device for a thin-walled steel raw material cutting production line, comprising a processing table 1, on which two groups of leveling mechanisms 2 are arranged; the two groups of leveling mechanisms 2 are point-symmetrically distributed; the leveling mechanism 2 on the left is relatively fixed to the processing table 1, and the leveling mechanism 2 on the right slides relatively to the processing table 1; the leveling mechanism 2 comprises a bracket 3, on the inner side of which a first pressing plate 4 is arranged, the first pressing plate 4 is relatively fixed to the bracket 3, and second pressing plates 5 are arranged on both upper and lower sides of the first pressing plate 4, and the two second pressing plates 5 are symmetrically arranged about the first pressing plate 4; a driving mechanism is also arranged on the bracket 3 The driving mechanism can drive the two second pressing plates 5 to move synchronously relative to the first pressing plate 4; one of the second pressing plates 5 is provided with a feeding mechanism for conveying the steel strip; after the driving mechanism drives one of the second pressing plates 5 to cooperate with the first pressing plate 4 to flatten the deformed parts of the head and tail of the steel strip, a cavity for accommodating the steel strip will be formed between the other second pressing plate 5 and the first pressing plate 4; the feeding mechanism can convey the tail of the old steel strip to the cavity on the right, and the tail of the new steel strip to the cavity on the left. At this time, the new steel strip and the old steel strip are in a superimposed state, and there is a certain gap in the middle. When cutting, the incisions of the new steel strip and the old steel strip are kept consistent.

[0016] During operation, after the previous roll of steel strip is used up, the tail of the old steel strip is located on the leveling mechanism 2 on the left, and is located between the first pressing plate 4 and the second pressing plate 5 above. The driving mechanism can drive the two second pressing plates 5 to move synchronously toward the side close to the first pressing plate 4, and the second pressing plate 5 above will cooperate with the first pressing plate 4 to flatten the tail of the old steel strip. When the second pressing plate 5 above moves to the position of completely flattening the tail of the old steel strip, the height of the cavity between the second pressing plate 5 below and the first pressing plate 4 is the same as the thickness of the steel strip. After the staff replaces the new steel strip, they pull the head of the new steel strip onto the leveling mechanism 2 on the right, so that the new steel strip The head of the belt is located between the first pressing plate 4 and the second pressing plate 5 below, and then the driving mechanism can drive the two second pressing plates 5 to move synchronously toward the side close to the first pressing plate 4, and the second pressing plate 5 below will cooperate with the first pressing plate 4 to flatten the head of the new steel belt. When the second pressing plate 5 below moves to the position of completely flattening the head of the new steel belt, the height of the cavity between the second pressing plate 5 above and the first pressing plate 4 is the same as the thickness of the steel belt; then the leveling mechanism 2 on the right will drive the head of the new steel belt to move toward the side close to the leveling mechanism 2 on the left, until the two first pressing plates 4 are close to each other and the two first pressing plates 4 are in a flush state, and then The two sets of feeding mechanisms can start working; the feeding mechanism on the left leveling mechanism 2 will transport the tail of the old steel strip to the right, and the tail of the old steel strip will move to the cavity formed by the first pressing plate 4 on the right and the second pressing plate 5 above; similarly, the feeding mechanism on the right leveling mechanism 2 will transport the head of the new steel strip to the left to the cavity formed by the first pressing plate 4 on the left and the second pressing plate 5 below; it should be noted that, since the two sets of leveling mechanisms 2 are close to each other at this time, the tail and head of the steel strip can move a short distance after leaving the leveling mechanism 2 to enter the adjacent cavity, formed by the first pressing plate 4 and the second pressing plate 5 The height of the formed cavity is the same as the thickness of the steel strip. The cavity will constrain the steel strip again in the up and down directions, which can ensure that the irregular parts of the head and tail of the steel strip will not rebound after being flattened. The feeding mechanism can stop working after the part to be cut moves into the cavity; at this time, the old steel strip and the new steel strip are arranged in an overlapping manner. In the subsequent cutting process, the new steel strip and the old steel strip can be cut at the same time, and the cross-sections of the old steel strip and the new steel strip can fit perfectly, so the welding can be more secure during welding; and a gap is left between the old steel strip and the new steel strip (separated by the thickness of the first pressing plate 4), which can facilitate the subsequent shedding of waste.

[0017] Specifically, Figure 2 As shown, the driving mechanism includes a connecting rod 6 and a first cylinder 8; the connecting rod 6 is provided with two groups, one end of the two groups of connecting rods 6 is respectively hinged to two second pressure plates 5, and the other end is commonly hinged with a first slider 7, and the first slider 7 is elastically slidably connected to the first pressure plate 4; the first cylinder 8 is installed on the bracket 3 and the piston end is fixedly connected to the second pressure plate 5.

[0018] During operation, the cylinder 8 can drive one of the second pressure plates 5 to move closer to the first pressure plate 4, and the second pressure plate 5 will drive the other second pressure plate 5 to move synchronously closer to the first pressure plate 4 through the connecting rod 6 until the second pressure plate 5 presses the head or tail of the steel strip. Since the two second pressure plates 5 are symmetrically arranged about the first pressure plate 4, a cavity with a height the same as the thickness of the steel strip will be formed between the other second pressure plate 5 and the first pressure plate 4.

[0019] Specifically, Figure 2 As shown, the feeding mechanism includes a conveying roller 9, which is rotatably connected to the second pressing plate 5, and a motor for driving the conveying roller to rotate is transmission-connected to the rotating shaft.

[0020] During operation, the conveying roller 9 can be driven to rotate by a motor (not shown in the figure), and the conveying roller 9 can drive the head or tail of the steel strip to move by friction.

[0021] Specifically, Figure 2 As shown, the outer side of the conveying roller 9 is made of rubber.

[0022] During operation, the outer side of the conveying roller 9 is made of rubber material, so that the contact area between the conveying roller 9 and the steel belt can be larger, and the conveying roller 9 can better convey the head and tail of the steel belt.

[0023] Specifically, Figure 3 As shown, a centering device is also provided on the side of the conveying roller 9, and the centering device includes two symmetrically arranged push blocks 10, and the push blocks 10 are elastically slidably connected to the second slider 11 in the vertical direction, and the second slider 11 is elastically slidably connected to the second pressure plate 5 in the horizontal direction; a first traction rope 12 is fixedly connected to the push block 10, and the first traction rope 12 is fixedly connected to a slide rod 13 at one end away from the push block 10, and a wedge block 14 capable of driving the slide rod 13 to move is provided on the side of the slide rod 13, and the wedge block 14 is fixedly connected to a rack rod 15, and the rack rod 15 is elastically slidably connected to the second pressure plate 5, and the rack rod 15 is meshed with a first gear 16, and the first gear 16 is meshed with a second gear 17, and the second gear 17 is fixedly installed on the rotating shaft of the conveying roller 9.

[0024] During operation, when the conveying roller 9 rotates to convey the steel belt, the conveying roller 9 will drive the first gear 16 to rotate synchronously through the second gear 17, and the first gear 16 will drive the rack rod 15 to move toward the side close to the slide bar 13, and the rack rod 15 will drive the wedge block 14 to move synchronously, and the wedge block 14 will drive the slide bar 13 to move upward, and the slide bar 13 will drive the two second sliders 11 to move toward each other through the first traction rope 12, and the two sliders 11 will drive the push block 10 to correct the head or tail of the leveled steel belt, so that the steel belt can be located in the middle of the first pressure plate 4, so that the new and old steel belts can be more neat when superimposed, and it can be ensured that the cutting surfaces of the new and old steel belts are better fitted together during subsequent cutting.

[0025] Specifically, Figure 4 and Figure 5 As shown, two limit blocks 18 for fixing the first pressure plate 4 are installed on the bracket 3 on the right; the two limit blocks 18 are distributed up and down, the upper limit block 18 is elastically slidably connected to the first pressure plate 4 in the vertical direction, and the lower limit block 18 is slidably connected to the first pressure plate 4 in the horizontal direction; the side of the upper limit block 18 is provided with a push rod 19 capable of driving it to move, and the push rod 19 is fixedly connected to the upper second pressure plate 5; the side of the upper limit block 18 is provided with a mounting frame 20, and a plurality of equidistantly distributed pressure blocks 21 are arranged in the mounting frame 20 along the sliding direction of the upper limit block 18, and the pressure blocks 21 are elastically slidably connected to the mounting frame 20 and can fix the upper limit block 18; the mounting frame 20 is connected to the lower limit block 18 by a second traction rope 22; the lower limit block 18 is fixedly connected with a second cylinder 23 for driving it to move.

[0026] During operation, after the cutting of the tail and the irregular parts of the head of the old steel strip is completed, since the new steel strip is located below the old steel strip at this time, the new steel strip needs to be moved upward to a position flush with the old steel strip before welding; first, the second cylinder 23 drives the lower limit block 18 to move outward, and the lower second limit block 18 cancels the limit on the first pressing plate 4 on the right, and then the first cylinder 8 on the right drives the second pressing plate 5 and the first pressing plate 4 to move upward as a whole until the first pressing plate 4 contacts the upper limit block 18, and at this time the first pressing plate 4 on the right moves upward to the right of the second pressing plate 5 on the upper left side, and at this time the new steel strip is located to the right of the old steel strip, and then the welding robot can start the welding operation; it should be noted that, considering that when processing steel strips of different thicknesses, the height of the overall upward movement of the first pressing plate 4 and the second pressing plate 5 will vary; such as Figure 6As shown, before welding, the second pressing plate 5 at the lower right side needs to be moved upward to be flush with the first pressing plate 4 at the left side. Therefore, the second pressing plate 5 at the lower right side needs to be moved upward to a height h2 (at this time, it is a state of clamping the leveled steel strip), and in the initial state, the height between the top surface of the second pressing plate 5 at the lower right side and the top surface of the first pressing plate 4 is h1. In the initial state, the distance between the bottom surfaces of the two limit blocks 18 is equal to h1. When the second pressing plate 5 moves the pressed steel strip toward the side of the first pressing plate 4, the upper second pressing plate 5 will drive the upper limit block 18 to move downward synchronously through the push rod 19. After the pressed steel strip of the second pressing plate 5 stops moving, the upper limit block 18 also stops moving synchronously. At this time, the two limit blocks 18 The distance between the bottom surfaces is equal to h2; when the lower limit block 18 moves outward to cancel the limit on the first pressure plate 4, the lower limit block 18 will drive the installation frame 20 and the pressure block 21 to move toward the side close to the upper limit block 18 through the second traction rope 22, and the pressure block 21 located on the positive side of the upper limit block 18 will be collected into the installation frame 20, and at the same time, a certain pressure will be applied to the upper limit block 18, and the other pressure blocks 21 will limit the upper limit block 18, which can ensure that the upper limit block 18 can remain fixed even after it is out of contact with the push rod 19. When the first pressure plate 4 on the right side moves upward to contact with the upper limit block 18, the new and old steel belts are just in an aligned state, which can make the new and old steel belts better welded.

[0027] Specifically, Figure 1 As shown, a slide rail 24 is laid on the top of the processing table 1; a slide seat 25 matching the slide rail 24 is fixedly installed at the bottom of the right side bracket 3, and a horizontal hydraulic cylinder 26 is fixedly connected to the slide seat 25, which can drive the leveling mechanism 2 on the right side to move along the slide rail 24.

[0028] During operation, the slide 25 can be driven by the horizontal hydraulic cylinder 26 to drive the leveling device 2 on the right side to move as a whole.

[0029] Specifically, Figure 7 As shown, the processing table 1 is composed of four columns 27 and four beams 28, and the columns 27 and the beams 28 are all made of square steel pipes.
