A system and method for intelligent production and processing of cold-rolled sheet products

technical field

The invention belongs to the field of steel plate processing, and more particularly relates to an intelligent production and processing system and method for cold-rolled sheet products.

Background technique

Among the current technologies, steel coils are a kind of commonly used raw materials, such as automobile shells in the field of automobile manufacturing, various steel thin pipes, and can be directly processed into various steel plates, steel strips, etc. When using steel coils for further processing, the coils first need to be uncoiled to form flat steel sheets and cut to size. In the uncoiling process, multiple devices such as uncoiler, feeding trolley, and material transport rack are required.

In the traditional technology, before the uncoiling process of the steel coil, the steel coil is usually hoisted to the conveying rack, and then the steel coil is sent to the steel coil machine by the loading trolley for uncoiling. However, the operation of hoisting and transporting the steel coil is cumbersome, and it is difficult to align the position and orientation of the steel coil with the uncoiler when the steel coil is transported to the conveying rack, requiring multiple adjustments, which is time-consuming and labor-intensive. Therefore, some devices for transporting steel coils have also appeared on the market.

The silicon steel coil is automatically transported through the setting of the docking trolley, and the structure design is reasonable. , On the basis of the laser navigation forklift AGV body, safety protection is added, and intelligent operation is improved, so that the coil material is not easy to fall during the transfer process, the handling is more stable, and the safety is improved. However, the manufacturing cost of the docking trolley is relatively high, and because the device structure on the docking cart is relatively precise, the maintenance cost and energy are greatly increased.

The utility model has scientific design, easy operation and maintenance, can save some space and time, save some funds, and effectively meet the process requirements. and feeding difficulties. However, this solution does not actually solve the problem of the traditional steel coil hoisting. The steel coil needs to be transported from other places to the trolley, and then sent from the trolley to the loading trolley. As for the steel coil from other places The steps of transporting to the trolley are not described in the scheme.

Detailed ways

The present invention will be further described below with reference to specific embodiments and accompanying drawings.

Example 1

As shown in Figure 4 and Figure 6, a cold-rolled steel coil transport trolley is mainly used to transport the steel coil from the storage place to the uncoiling position when the cold-rolled steel coil is uncoiled, so that the end face of the steel coil is facing the uncoiler on the uncoiler. The expansion and contraction reel 102 is convenient for the feeding trolley 2 to accurately place the steel coil sleeve on the expansion and contraction reel 102 . The specific structure and working principle of the material transport trolley 4 will be described in detail below.

The material transport trolley 4 includes a base 401 as an installation body, a wheel 402 installed at the lower end of the base 401 , a support arm 403 for holding up the steel coil, a support arm lifting device 404 and a connecting arm 406 . The supporting arm lifting device 404 is installed on the base 401, and all lifting devices in the prior art can be used as the supporting arm lifting device 404, as long as the connecting arm 406 and the supporting arm 403 can be driven to lift and lower, this embodiment adopts a worm gear wire The rod lift, since its structure and installation process belong to the prior art known to those skilled in the art, will not be described in detail here; The support arm 403 provides installation space; the support arm 403 is a cylindrical structure connected with the connecting arm 406, and its axis is in the horizontal plane and perpendicular to the length direction of the connecting arm 406; the wheels 402 have multiple, usually four, and are symmetrically installed on the The lower end of the base 401 is driven to work by a driving device. In this embodiment, the driving device adopts a wheel motor 411 .

When the material transport trolley 4 is working, the wheel motor 411 works to drive the material transport trolley 4 to move to the front of the steel coil to be transported, and the support arm 403 is inserted into the inner hole of the steel coil. After one end, the support arm lifting device 404 works to drive the support arm 403 to lift up the steel coil. Then, the wheel motor 411 drives the material transport trolley 4 to move to the material support frame 3 to place the steel coil on the material support frame 3 .

In order to prevent the steel coil from sliding off the support arm 403 when the support arm 403 transports the steel coil, two baffles 405 are arranged on the support arm 403 along its length direction, and the baffle plates 405 are hollow discs matching the direction of the support arm 403 shaped structure, and is fixedly sleeved on the support arm 403. When the steel coil slides on the support arm 403, it will be blocked by the baffle 405, so as to avoid the danger of the steel coil sliding down. It should be noted that the distance between the two baffles 405 should be greater than the width of the steel coil, and the specific distance is determined according to the width of the steel coil during actual production. Usually, the distance is 5-10cm greater than the width of the steel coil.

In order to make the lifting process of the support arm 403 more stable, a pair of guide rods 408 in the vertical direction are symmetrically installed on the connecting arms 406 on both sides of the support arm lifting device 404 in this embodiment, and the guide rods 408 pass through the connecting arms 406 to connect with The arm 406 is movably connected, and one end of the arm 406 is fixedly mounted on the base 401 . The guide rod 408 plays a certain supporting role on the connecting arm 406 on the one hand, and also plays a guiding role on the other hand, so that the connecting arm 406 can be raised and lowered more stably.

In addition, in the existing uncoiler system, the steel coil sleeve is usually put on the expansion and contraction drum 102 of the decoiler 1 through the loading trolley 2 installed in the pit. However, when the loading trolley 2 transports the steel coil, the facing direction of the end face of the steel coil remains unchanged. Therefore, when placing the steel coil on the pallet 3, the end face of the steel coil needs to face the uncoiler 1. The expansion and contraction reel 102 is formed, so that the loading trolley 2 can directly sleeve the inner hole of the steel coil on the expansion and contraction reel 102 . If the end face of the steel coil is not directly facing the expansion and contraction reel 102, it is likely that it cannot be nested on the expansion and contraction reel 102, so secondary adjustment is required, which affects the uncoiling efficiency. As mentioned in the background art, when the steel coil is transported to the pallet 3 in the prior art, the position of the steel coil is not accurately placed, and multiple adjustments are required, resulting in poor handling efficiency or accurate placement, but the handling device the problem of high cost. In this regard, this embodiment provides the following solutions, which can solve the above problems through a simple structure, the steel coils are placed accurately, the manufacturing cost is extremely low, the maintenance is convenient when problems occur, and the use value is extremely high. The structure and working principle of the scheme are described in detail.

First, the rear end of the support arm 403 is hingedly connected to the connecting arm 406 through the connecting arm 406 . The distance between the horizontal through holes 4061 in the length direction of the connecting arm 406 is greater than the diameter of the support arm 403, the support arm 403 passes through the horizontal through hole 4061, and a vertical through hole 4061 is provided on the upper and lower sides of the support arm 403. Straight positioning hole, by passing the positioning rod 413 through the vertical through hole and the vertical positioning hole, the support arm 403 is fixed on the connecting arm 406, wherein the positioning rod 413 is fixedly connected with the connecting arm 406, and the support arm 403 is Hinged connection. Therefore, in the horizontal through hole 4061, the support arm 403 can only swing along the circumferential direction of the positioning rod 413, and will not swing up and down to affect the placement of the steel coil.

Next, on the connecting arm 406, on the side face close to the rear end of the support arm 403, a fixing block 4062 is arranged, and the fixing block 4062 is provided with a hinge seat, the cylinder of the hydraulic cylinder I 407 is hingedly mounted on the hinge seat, and its piston is mounted on the hinge seat. The rod is hingedly connected with the rear end of the support arm 403, and the hydraulic cylinder I 407 and the connecting arm 406 are kept in a parallel state. Therefore, when the material transporting trolley 4 transports the steel coil to the front of the material support frame 3, the hydraulic cylinder I 407 expands and contracts, drives the support arm 403 to swing left and right along the circumferential direction of the positioning rod 413, and adjusts the position of the steel coil. For the expansion and contraction reel 102 of the uncoiler 1, the hydraulic cylinder 1 407 stops working, the support arm lifting device 404 descends, and the steel coil is placed on the support frame 3.

The above solution effectively solves the problem of placing the steel coils, but when the steel coils are transported, the movement of the material transport trolley 4 is very unstable due to the heavy steel coils themselves. In order to balance the weight on both sides of the feeding trolley 4, in this embodiment, a counterweight 412 is provided on the base 401 for balancing the weight of the steel coil. In addition, in order to further ensure the stability of the material transport trolley 4 when moving, some improvements are also made at the wheel 402 and the wheel motor 411 of the material transport trolley 4 in this embodiment.

As shown in FIG. 5 , between a pair of wheels 402 whose axes are on the same straight line, a synchronizing shaft 409 is used for transmission connection to ensure the movement synchronization of the two wheels 402 . Next, a hollow case 410 is installed in the middle of the synchronizing shaft 409 , and the synchronizing shaft 409 passes through the case 410 . A driven gear is fixedly sleeved on the synchronizing shaft 409 inside the box body 410, and at the same time, the wheel motor 411 is fixedly installed on the box body 410, and its output shaft is drivingly connected to a driving gear that meshes with the driven gear, so that when When the wheel motor 411 is working, the driving gear rotates to drive the driven gear to rotate, which in turn drives the synchronous shaft 409 and the wheels 402 at both ends of the synchronous shaft 409 to move synchronously.

In this way, when a single motor is drive-connected to one wheel 402, the phenomenon that the wheel 402 connected to the motor is suspended in the air due to the unevenness of the road surface may cause instability of the entire material transport trolley 4. In addition, directly driving the middle of the synchronizing shaft 409 to rotate also ensures the synchronization of the motion of the wheels 402 at both ends as much as possible, preventing the phenomenon that the synchronizing shaft 409 or the wheels 402 are damaged due to different torques. It should be noted that the synchronizing shaft 409 may be selectively installed between one pair of wheels 402 or two pairs of wheels 402 according to actual conditions.

To sum up, the cold-rolled steel coil transport trolley of this embodiment has a simple structure, low manufacturing cost, can quickly and conveniently transport the steel coil to the material transport rack, is simple to operate, and does not need to adjust the position of the trolley many times. , The coil handling efficiency is greatly improved.
