Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel plate processing, and particularly relates to a flexible loading and unloading mechanism for a stainless steel plate sink. Background Art

[0002] Austenitic stainless steel refers to stainless steel with austenite structure at room temperature. The pressure processing process of ordinary austenitic stainless steel plates successively adopts processes such as slab heating, rolling, solution heat treatment, straightening, shot blasting, pickling, manual grinding, and packaging. Among them, the main purpose of solution heat treatment is to obtain good service performance. The solution treatment of ordinary austenitic stainless steel: The austenitic stainless steel is heated to 1000-1150 °C to dissolve all carbides into austenite, and then a single-phase austenite structure is obtained by water cooling or rapid cooling. Currently, the commonly used quenching water cooling process for austenitic stainless steel plates includes: 1. Roller quenching: The steel plate is conveyed to the water spraying area through the gap between the upper and lower roller paths for quenching. The quenching cooling rate of this scheme is very high, but high water consumption is required for strong cooling during the cooling process. It is necessary to configure a water supply capacity of more than about 7000m 3 / h to meet the quenching requirements of stainless steel, so there is a problem of large water consumption; when the thickness of the stainless steel plate increases, the cost of the quenching equipment increases significantly. 2. Unconstrained quenching: The steel plate is conveyed through the roller path into the water spraying area to quench the steel plate during movement. This scheme has no upper roller path compared with roller quenching, has a higher cooling rate, and a simple process. The required water supply capacity is above 900m 3 / h, and the water supply volume is smaller than that of roller quenching, but the flatness of the plate after quenching reaches 20-40mm / m, and the qualified rate of the primary internal material performance is relatively low. The inventor has found through research that: By cooling the stainless steel plate after spray quenching in a water tank quenching method, the water supply volume during the solution heat treatment quenching process can be greatly reduced, and the actual water supply volume can be controlled within 800m 3 / h. This scheme requires moving the stainless steel plate cooled by spray from the transfer roller path to the water tank for cooling, and then moving it back to the transfer roller path from the water tank and performing subsequent processes such as shot blasting, straightening, pickling, manual inspection / grinding, and packaging. In practice, when the stainless steel plate is taken out of the water tank, a part of the cooling water usually remains on its upper and lower surfaces, and this part of the cooling water will affect the subsequent shot blasting process. Therefore, how to develop a flexible loading and unloading mechanism for a stainless steel plate sink to overcome the above problems in the prior art is the direction that those skilled in the art need to further study. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a flexible loading and unloading mechanism for a stainless steel plate sink, which can transfer the stainless steel plate between the transfer roller path and the water tank to realize the cooling of the stainless steel plate by water tank quenching after spray quenching, and avoid the problem of cooling water remaining on the upper surface of the stainless steel plate.

[0004] The utility model discloses a flexible loading and unloading mechanism for a stainless steel plate sink, which comprises:

[0005] A base, on which a conveying roller path and a cooling water tank are provided. The conveying roller path extends along the x-axis direction and includes a plurality of conveying roller cylinders that are parallel to each other and of equal length, and the conveying roller path is used for conveying stainless steel plates; the cooling water tank is located on one side of the conveying roller path in the y-axis direction;

[0006] A support mechanism, which includes two gantry frames arranged in parallel. The cross beams of the two gantry frames extend along the y-axis direction respectively and are located above the conveying roller path and the cooling water tank;

[0007] A rectangular blanking frame, on which 4 hook mounting blocks are symmetrically installed on the frame body;

[0008] A lifting mechanism, which is movably installed on the cross beam of each gantry frame; four lifting motors are installed on the lifting mechanism, the output shafts of each lifting motor are respectively coaxially connected with a winding drum, and a suspension cable is respectively wound on each winding drum. One end of each suspension cable is respectively connected with a lifting hook; the four lifting hooks are respectively detachably installed on the four hook mounting blocks;

[0009] A driving mechanism, which is connected to the lifting mechanism and is used to drive the lifting mechanism to reciprocate along the cross beam.

[0010] By adopting the following technical solution: the rectangular blanking frame is configured to be initially located on one side of the cooling water tank on the conveying roller path. When the stainless steel plate after spray processing moves along the conveying roller path to one side of the cooling water tank, at this time, the stainless steel plate moves above the rectangular blanking frame. At this time, operate each lifting mechanism to start synchronously and drive each winding drum to rotate synchronously, lifting the rectangular blanking frame and the stainless steel plate from the conveying roller path. Subsequently, the driving mechanism drives the lifting mechanism to move along the cross beam to above the cooling water tank. At this time, each lifting mechanism rotates in the opposite direction synchronously and drives each winding drum to rotate in the opposite direction, immersing the rectangular blanking frame and the stainless steel plate in the cooling water tank to achieve quenching in the water tank. Thus, the stainless steel plate is cooled in two ways: spray quenching and water tank quenching in sequence. Subsequently, each lifting mechanism starts to lift the rectangular blanking frame and the stainless steel plate from the cooling water tank. At this time, by controlling the rotation speeds of each lifting motor differently, the frame body of the rectangular blanking frame can be inclined towards the cooling water tank (in practice, to avoid the stainless steel plate from slipping, the inclination angle of the frame body is controlled within 6-15 degrees along the plate width or plate length direction), so that the cooling water on the upper surface of the plate body of the stainless steel plate flows into the cooling water tank. On the one hand, it avoids the influence of the cooling water remaining on the upper surface of the stainless steel plate on the subsequent processes. On the other hand, the cooling water returns to the cooling water tank, reducing the loss of the cooling water in the cooling water tank during the processing. At the same time, there is no need to additionally set up devices such as a blowing mechanism to blow off the cooling water remaining on the upper surface of the stainless steel plate, simplifying the system cost. Subsequently, control the rectangular blanking frame to move back to the initial position, so that the stainless steel plate continues to move along the conveying roller path to the next process.

[0011] Preferably, the rectangular blanking frame includes a plurality of cross bars that are parallel to each other, of equal length and at equal intervals, and two longitudinal baffles fixedly connected to both ends of the rod bodies of each cross bar; two hook mounting blocks are respectively installed at both ends of the plate bodies of each longitudinal baffle; the length of the rod body of the cross bar is greater than the length of the barrel of the conveying roller, and the height of the frame body of the rectangular blanking frame is lower than the height of the barrel of the conveying roller.

[0012] By adopting this technical solution: since the length of the rod body of the cross bar is longer than the length of the barrel of the conveying roller and the height of the frame body of the rectangular blanking frame is lower than the height of the barrel of the conveying roller, the rectangular blanking frame will not hinder the movement of the stainless steel plate along the conveying roller path when it is moved and placed on the conveying roller path.

[0013] Preferably, a y-axis I-beam is respectively provided on the upper surfaces of the two cross beams; the hoisting mechanism includes a mounting frame, the mounting frame includes two x-axis strip plates and two groups of positioning plates, the two x-axis strip plates are configured to be of equal length and parallel to each other; two mounting plates are respectively and fixedly mounted on the two x-axis strip plates, and each hoisting motor is respectively mounted on each mounting plate; the two groups of positioning plates are fixedly mounted on the upper sides of the plates of the two x-axis strip plates; the four wire winding drums are grouped in pairs and respectively mounted on the two groups of positioning plates (each group of positioning plates includes two parallel positioning plates, and both ends of each wire winding drum are rotatably mounted between the two positioning plates of a group of positioning plates); a plurality of rollers are respectively mounted on the two x-axis strip plates, and the rollers mounted on the two x-axis strip plates are respectively mounted on the two y-axis I-beams and can respectively roll along the two y-axis I-beams.

[0014] By adopting this technical solution: the two groups of positioning plates are used to install and position each wire winding drum, and the structural cooperation between the rollers and the y-axis I-beam satisfies the relative movement between the hoisting mechanism and the gantry.

[0015] Preferably, at least one of the rollers mounted on the two x-axis strip plates is a driving wheel; the driving mechanism includes a driving motor, the output shaft of the driving motor is connected to the driving wheel and used to drive the driving wheel to rotate; the driving motor is fixedly mounted on the lower side of the plate of one of the x-axis strip plates.

[0016] By adopting this technical solution: the driving motor rotates to drive the driving wheel to rotate in the y-axis I-beam into which it extends, and then drives the other rollers to respectively rotate synchronously in the y-axis I-beam into which they extend, thereby realizing the reciprocating movement of the hoisting mechanism along the cross beam.

[0017] Preferably, the stainless steel plate is a stainless steel plate with a maximum thickness of 116 mm.

The length of the rod body of the cross bar 330 is configured to be longer than the length of the barrel body of the conveyor roller 111, and the height of the frame of the rectangular blanking frame is lower than the height of the barrel body of the conveyor roller 111.

[0033] The hoisting mechanism is movably installed on the cross beams 211 of the gantry frames 210. Specifically: The hoisting mechanism includes a mounting frame, the mounting frame includes two x-axis strip plates 410 and two groups of positioning plates 420, and the two x-axis strip plates 410 are configured to be equal in length and parallel to each other; Two mounting plates 430 are respectively fixedly installed on the two x-axis strip plates 410, and a hoisting motor 440 is respectively installed on each mounting plate 430 (that is, there are four mounting plates 430 on the hoisting mechanism, and a hoisting motor 440 is respectively installed on the four mounting plates 430). The output shafts of the hoisting motors 440 are respectively coaxially connected with a winding drum 450, a suspension cable 460 is respectively wound and installed on each winding drum 450, and one end of each suspension cable 460 is respectively connected with a hoisting hook 470; The four hoisting hooks 470 are respectively detachably installed on the four hook mounting blocks 310; The two groups of positioning plates 420 respectively include two parallel positioning plates 420, and the two groups of positioning plates 420 are respectively fixedly installed on the upper sides of the plate bodies of the two x-axis strip plates 410.

[0034] The four winding drums 450 are installed in two groups respectively on the two groups of positioning plates 420 (both ends of the four winding drums 450 are respectively rotatably installed on the two positioning plates 420 of a group of positioning plates 420); Two rollers are respectively installed on the two x-axis strip plates 410 (that is, a total of four rollers are installed on the mounting frame), and the two rollers installed on the two x-axis strip plates 410 are respectively installed in the two y-axis I-beams 212 and can respectively roll along the two y-axis I-beams 212. (In this example, one y-axis I-beam 212 is respectively installed in each of the y-axis I-beams 212, and each roller is respectively installed on the y-axis I-beam 212. For details, please refer to Figure 2The structure shown). The four rollers include a driving wheel 520 and three driven wheels 530.

[0035] In practice, its working process is as follows:

[0036] The rectangular blanking frame is configured to be initially located on one side of the cooling water tank 120 on the conveying roller path 110. When the stainless steel plate after spray processing moves along the conveying roller path 110 to one side of the cooling water tank 120, at this time, the stainless steel plate moves above the rectangular blanking frame. At this time, operate each lifting mechanism to start synchronously and drive each winding drum 450 to rotate synchronously to lift the rectangular blanking frame and the stainless steel plate from the conveying roller path 110. Subsequently, the driving mechanism drives the lifting mechanism to move along the cross beam 211 to above the cooling water tank 120. At this time, each lifting mechanism rotates reversely synchronously and drives each winding drum 450 to rotate reversely to immerse the rectangular blanking frame and the stainless steel plate in the cooling water tank 120 to achieve quenching in the water tank. Thus, the stainless steel plate is cooled in two ways of spray quenching and water tank quenching in sequence. Subsequently, each lifting mechanism starts to lift the rectangular blanking frame and the stainless steel plate out of the cooling water tank 120. At this time, by respectively controlling the rotation speeds of each lifting motor 440, the frame body of the rectangular blanking frame can be inclined towards the cooling water tank 120. (In practice, to avoid the stainless steel plate from slipping, the inclination angle of the frame body is controlled within 6-15 degrees along the plate width or plate length direction), so that the cooling water on the upper surface of the plate body of the stainless steel plate flows into the cooling water tank 120. On the one hand, it avoids the influence of the cooling water remaining on the upper surface of the stainless steel plate on the subsequent processes. On the other hand, the cooling water returns to the cooling water tank 120, reducing the loss of cooling water in the cooling water tank 120 during the processing. At the same time, there is no need to additionally set up devices such as a blowing mechanism to blow off the cooling water remaining on the upper surface of the stainless steel plate, simplifying the system cost. Subsequently, control the rectangular blanking frame to move back to the initial position, so that the stainless steel plate continues to move along the conveying roller path 110 to the next process.

[0037] In the above process: The stainless steel plate finishes quenching in the spray area. The stainless steel plate is controlled according to the process of thickness with respect to the inlet water tank temperature and the outlet water tank temperature as shown in the following table:

[0038]

[0039] The cooling time of the stainless steel plate in the cooling water tank 120 is h, where h ≥ (1 - 2,3) × H seconds, the unit of the steel plate thickness H is mm, and the temperature when leaving the water tank is ≤ 100°C. When the thickness H of the stainless steel plate ≤ 10 mm, the time coefficient is taken as 1, and at this time the temperature of the stainless steel plate entering the water tank is 600 - 720°C; when the thickness 10 mm < H ≤ 25 mm of the stainless steel plate, the time coefficient is taken as 1.5, and at this time the temperature of the stainless steel plate entering the water tank is 605 - 736°C; when the thickness 25 mm < H ≤ 35 mm of the stainless steel plate, the time coefficient is taken as 2, and at this time the temperature of the stainless steel plate entering the water tank is 610 - 750°C; when the thickness 35 mm < H ≤ 112 mm of the stainless steel plate, the time coefficient is taken as 3, and at this time the temperature of the stainless steel plate entering the water tank is 615 - 800°C. When the rectangular blanking frame drives the stainless steel plate out of the cooling water tank 120, after leaving the water surface: the width direction of the frame is inclined at 6 - 15°, so that the cooling water on the upper surface of the plate body of the stainless steel plate flows back into the water tank under the action of gravity.

[0040] The above processing process improves the control ability of the plate shape flatness after quenching. The plate shape flatness after quenching is as follows: 1. More than 85% > 5 - 18 mm / m; 2. The rest > 18 - 28 mm / m; which meets the requirements of the subsequent straightening process. The flatness of the stainless steel plate after straightening is ≦ 5 mm / m, meeting the high standards of the market and users. It improves and stabilizes the qualified rate of the performance of the first inner material of stainless steel, and stabilizes at more than 99.9%.

[0041] The above has described in detail the embodiments of the present invention in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, provided that these changes fall within the scope of the claims of the present invention and its equivalent technologies, they still fall within the protection scope of the present invention.
