Description

Technical Field

[0001] The invention relates to a cooling bed with lamination and delamination functions, belonging to the technical field of metallurgical equipment. Background Art

[0002] At present, when steel mills produce flat steel, the general production process is as follows: the steel billet is heated to the process temperature in the heating furnace, and then enters the rolling equipment to roll the steel billet until it reaches the required specifications. The rolled flat steel needs to enter the cooling bed for straightening and cooling. Figure 1 As shown, the stepping rack cooling bed mainly includes a straightening grid for receiving incoming steel and straightening; a fixed rack and a movable rack. The fixed rack and the movable rack are used for step-by-step transmission of flat steel. The conveyor chain is located at the end to receive the flat steel and output it in sequence.

[0003] According to the production of different specifications, the cooling speed of various products is different, while the cooling bed step speed is generally fixed. In order to meet the cooling speed requirements of some special products (mainly slow cooling), two flat steels need to be stacked and cooled together during production, that is, two flat steels are stacked and slowly cooled. Figure 1 The cooling bed shown in FIG. 1 does not have this function, so it is necessary to design a cooling bed with the functions of stacking and unstacking the sheets. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a cooling bed with stacking and de-stacking functions in response to the above-mentioned existing technology. The cooling bed can stack flat steel at the entrance to achieve the superposition of two or more flat steels, and de-stacking the stacked flat steels at the exit so that the stacked flat steels can be transferred to the conveyor chain in sequence.

[0005] The technical solution adopted by the present invention to solve the above problems is: a cooling bed with stacking and de-stacking functions, which includes a straightening grid, a fixed rack, a movable rack and a conveyor chain. The straightening grid is connected to the fixed rack front and back. The front end of the straightening grid is provided with a material receiving slope, and a stacking groove is provided at the bottom position of the material receiving slope. Two or more pieces of steel are stacked at the stacking groove to form stacked steel. The movable rack is used to convey the stacked steel in a step-by-step manner along the tooth hooks on the straightening grid and the fixed rack toward the conveyor chain; the end position of the movable rack is provided with a de-stacking tooth hook, and the de-stacking tooth hook has a de-stacking slope. The de-stacking slope is used to receive and de-stacking the stacked steel at the end of the fixed rack and transfer it to the conveyor chain in sequence.

[0006] As one of the implementation modes of the present application, the stripping teeth are hooked behind the terminal bevel teeth of the movable rack.

[0007] As one of the embodiments of the present application, the split teeth are provided on the splitting slope. When the stacked steel moves along the splitting slope toward the conveyor chain, the split teeth intercept the steel at the bottom of the stacked steel and make the steel at the top slide forward first. The movement trajectory of the split teeth intersects with the conveyor chain, so that the steel retained at the split teeth can be smoothly transferred to the conveyor chain.

[0008] As one embodiment of the present application, the split teeth have multiple levels, with the number of split teeth being one less than the number of stacked steel sheets. Each level of split teeth sequentially intercepts the bottommost piece of steel in the stack, separating the stack in sequence. This allows for the separation of multiple steel sheets, allowing the stack to be separated sequentially on the splitting slope.

[0009] A more reasonable setting is that the height of the teeth protruding relative to the splitting slope is no higher than the thickness of the bottom steel in the stack, so that only the bottom steel in the stack is retained and the upper steel moves forward smoothly.

[0010] As one of the embodiments of the present application, the stripping tooth hook is arranged at the end of the movable rack through the first tooth hook mounting seat and the first connecting bolt. The stripping tooth hook can be flipped around the first connecting bolt in the direction of incoming steel or feeding steel, so that the stripping tooth hook is designed as an optional function. Whether to use the stripping tooth hook can be selected according to whether the steel is stacked, and stripping tooth hooks of different specifications (tooth height and quantity) can be selected according to the specifications of the steel and the amount of stacked steel.

[0011] As one embodiment of the present application, first positioning blocks are provided on both sides of the first hook mounting base. When the stripping hook is flipped in the direction of incoming steel or in the direction of feeding steel, it is supported on the first positioning block on the corresponding side. By using the positioning blocks, the stripping hook can be accurately positioned at the tail end of the movable rack.

[0012] As one of the embodiments of the present application, a stopper hook is also provided at the end of the movable rack. When there is no need to stack or split the stacked steel, the stopper hook transfers the steel at the end of the fixed rack directly to the conveyor chain. The stopper hook and the splitter hook can be switched according to the stacking requirements, thereby facilitating the flexibility of the cooling bed operation.

[0013] As one of the embodiments of the present application, the material blocking tooth hook has a material receiving bevel tooth and a material blocking inclined surface. The material blocking inclined surface is located behind the material receiving bevel tooth and is used to block the steel. The movement trajectory of the material receiving bevel tooth intersects with the conveyor chain, so that the steel at the material receiving bevel tooth can be smoothly received on the conveyor chain.

[0014] As one of the embodiments of the present application, the stopper hook is arranged at the end of the movable rack through a second hook mounting seat and a second connecting bolt, and the stopper hook can be flipped around the second connecting bolt in the incoming steel direction or the feeding steel direction.

[0015] As one embodiment of the present application, second positioning blocks are provided on both sides of the second tooth hook mounting base, and the stopper tooth hook is supported on the corresponding second positioning block when it is flipped in the direction of incoming steel or in the direction of feeding steel, thereby enabling the stopper tooth hook to be quickly positioned at the end of the movable rack.

[0016] As one of the embodiments of the present application, a gasket is provided in the lamination groove, and when steel stacking is not required, the gasket is used to fill the lamination groove.

[0017] Compared with the prior art, the advantages of the present invention are:

[0018] 1. The cooling bed designed in this application utilizes the lamination grooves at the bottom of the material receiving slope to stack two or more flat steel sheets together to form a stack. The depth of the lamination grooves can be designed based on the number of stacks. Driven by the moving rack, the stack advances along the helical teeth of the straightening grid and fixed rack, undergoing straightening and slow cooling during the process. After cooling, the stack is separated on the stripping slope by the stripping hooks at the end of the moving rack. The flat steel sheets then arrive at the conveyor chain in sequence, thus meeting the cooling speed requirements of certain products.

[0019] 2. The present application also movably arranges the sheet-stripping tooth hook and the material-blocking tooth hook at the end of the movable rack, which can switch between the stacking production mode and the single-piece production mode without affecting the original function of the cooling bed.

[0020] 3. The cooling bed designed in this application can be modified on the basis of the existing cooling bed, by removing the material blocking slope at the end of the existing moving rack and retaining only the material receiving slope, and then cooperating with the stripping tooth hook to complete the stripping and transportation of the stacked steel, or cooperating with the material blocking tooth hook to complete the transportation.

[0021] 4. The lamination grooves of the present application are designed with gaskets. When steel lamination is not required, the lamination grooves can be directly filled. Or when a smaller number of laminations is required, the thickness of the lamination grooves can be reduced by the gaskets. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0051] like Figures 2 to 8As shown, the cooling bed in this embodiment can meet the demand of stacking two pieces of flat steel and cooling them together during production. After the two pieces of flat steel are stacked and slow cooling is completed, the two stacks of steel are separated and transported to the conveyor chain in sequence.

[0052] It includes a straightening grid 1, a fixed rack 2, a movable rack 5 and a conveyor chain 3. The straightening grid 1 is connected to the fixed rack 2 front and back. The conveyor chain is located at the end of the fixed rack 2. The front end of the straightening grid 1 is provided with a material connecting slope 6. A stacking groove 7 is provided at the bottom of the material connecting slope 6. The depth of the stacking groove 7 is the thickness of a piece of flat steel. Two pieces of flat steel are stacked at the stacking groove 7 along the material connecting slope 6 to form stacked steel. The movable rack 5 has a circular motion trajectory driven by the eccentric wheel, and is used to step-by-step convey the stacked steel along the tooth hooks on the straightening grid 1 and the fixed rack 2 toward the conveyor chain 3.

[0053] The end of the movable rack 5 is provided with a stripping tooth hook 8, which has a stripping slope. The stripping slope extends toward the conveyor chain 3. The stripping slope is used to receive and split the stacked steel at the end of the fixed rack and transfer the split flat steel to the conveyor chain 3 in sequence. Specifically, a split tooth 9 is provided on the stripping slope. The height of the split tooth 9 relative to the stripping slope is the thickness of a single piece of flat steel. When the stacked steel reaches the stripping slope and slides along the stripping slope toward the conveyor chain 3, the split tooth 9 just intercepts the flat steel at the bottom, causing the flat steel at the top to slide forward first. The movement trajectory of the split tooth 8 should intersect with the conveyor chain 3. During the movement of the stripping tooth hook 8 following the movable rack, the steel stranded at the split tooth 8 is smoothly received by the conveyor chain 3. In this way, the splitting of the two flat steels is completed and they are transferred to the conveyor chain 3 one after the other.

[0054] The stripping hook 8 is mounted on the end of the movable rack 5 via a first hook mounting base 10 and a first connecting bolt 11. The stripping hook 8 can be flipped around the first connecting bolt 11 in both the incoming and outgoing directions. First positioning blocks 12 are provided on the front and rear sides of the first hook mounting base 10, respectively. When flipping, the stripping hook 8 rests on the corresponding first positioning block 12.

[0055] The end of the movable rack 5 is also provided with a material blocking tooth hook 13, which is located on the opposite side of the sheet-splitting tooth hook 8. The material blocking tooth hook 13 has a material receiving bevel tooth 1301 and a material blocking slope 1302. The material blocking slope 1302 is located behind the material receiving bevel tooth 1301 and is used to block the steel. The movement trajectory of the material receiving bevel tooth 13 intersects with the conveyor chain 3, so that the steel at the material receiving bevel tooth 1302 can be smoothly transferred to the conveyor chain. When the steel is not needed to be stacked or split, the material blocking tooth hook 13 directly transfers the steel at the end of the fixed rack 5 to the conveyor chain 3.

[0056] The stopper hook 13 is mounted on the end of the movable rack 5 via a second hook mounting base 14 and a second connecting bolt 15. The stopper hook 13 can be flipped in both the incoming and feeding directions around the second connecting bolt 15. Second positioning blocks 16 are provided on the front and rear sides of the second hook mounting base 14, and when flipping, the stopper hook 13 is supported on the corresponding second positioning block 16.

[0057] A gasket 17 is provided in the lamination groove 7 and is used to fill the lamination groove 7 when steel stacking is not required.

[0058] This application is to modify the end tooth of the existing movable rack and cut off the blocking bevel of the last tooth (see Figure 4 ), and a stripping hook 8 is installed at the end of the movable rack 5. The stripping hook 8 can rotate 180° around the first connecting bolt. When the movable rack 5 transports the two stacked flat steels 4 onto the stripping hook 8, the bottom piece of the stacked flat steel is blocked. The top piece, unobstructed, slides onto the conveyor chain before the bottom piece. Subsequently, the bottom piece is also smoothly placed on the conveyor chain as the movable rack 5 continues to move. The two flat steels are transported in parallel along the conveyor chain. Figure 6 It is a schematic diagram of disassembling two pieces of flat steel 4.

[0059] When lamination production is not required, that is, when single-piece flat steel is produced, a gasket 17 is used to fill the lamination groove 7 on the straightening grid, and at the same time, the stripping tooth hook 8 on the movable rack is turned 180° in the direction of the steel. At the same time, the blocking tooth hook 13 is installed opposite to the stripping tooth hook 8, and at the same time, the blocking tooth hook 13 is turned 180° in the direction of the steel around the second connecting bolt. The end of the movable rack is restored to a complete tooth, and production can be carried out normally one piece at a time.

[0060] When round steel needs to be produced (same as when lamination is not required), the stripping hook 8 used for lamination production is turned 180° toward the steel feeding direction of the cooling bed while filling the groove of the straightening grid. At the same time, the blocking hook 13 is installed opposite to the stripping hook 8. The blocking hook 13 is turned 180° toward the steel feeding direction around the second connecting bolt, so that the cooling bed is restored to the same state as before the modification.

[0061] The sheet removal hook 8 and the material blocking hook 13 are simultaneously installed at the end teeth of the movable rack 5. The two hooks can be turned 180 degrees toward the steel feeding direction or the steel feeding direction of the cooling bed. When a hook is needed, it is turned 180 degrees toward the steel tapping direction of the cooling bed, and the positioning block positions the hook.

[0062] In addition to the above embodiments, the present invention also includes other implementation methods. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the scope of protection of the claims of the present invention.
