Description

Technical Field

[0001] The utility model belongs to the field of blanking devices, and particularly relates to a steel strip shearing, slitting and blanking device. Background Art

[0002] The production process of steel strips includes shearing and slitting - winding - blanking. Shearing and slitting is the process of cutting wide - width steel into multiple narrow - width steel strips according to requirements. During winding, multiple narrow - width steel strips are wound on the same winding shaft to form multiple steel strip coils. Blanking is to take down the multiple steel strip coils on the winding shaft and then place them in a tray with a lower height.

[0003] In this blanking process, the steel strip coils are all carried down from the winding shaft by manpower. The weight of the steel strip coils is usually very heavy, and some even reach hundreds of kilograms. Moreover, the height of the winding shaft is very high. Workers need to repeatedly carry heavy objects and bend down and stand up, which will cause great damage to the workers' waist and back, and is very tiring, affecting the blanking efficiency. There is no device for automatically blanking steel strip coils in the prior art. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the utility model is to overcome the fact that the blanking of the wound steel strips after shearing and slitting depends on manual handling at present, which causes a large load on the physical health of workers, is easy to get tired, and affects the blanking efficiency.

[0005] To solve the above - mentioned technical problem, the utility model provides a steel strip shearing, slitting and blanking device, which includes a pushing mechanism and a trolley arranged along the X - axis direction. The pushing mechanism is fixed on the left side of the winding seat, and the trolley is located in front of the winding seat. The trolley can move bidirectionally along the X - axis and can be lifted.

[0006] Preferably, the trolley includes a tray, a chassis, scissor - type support rods, a first hydraulic cylinder and rollers. Rollers are arranged under the chassis, scissor - type support rods are arranged above the chassis, the cylinder body of the first hydraulic cylinder is fixed on the chassis to drive the scissor - type support rods to expand and contract, and the top of the scissor - type support rods fixes the tray.

[0007] Preferably, the pushing mechanism includes a pushing hydraulic cylinder, an upper guide rod, a lower guide rod, a pushing plate, an upper guide sleeve, a middle guide sleeve and a lower guide sleeve. The upper guide sleeve, the middle guide sleeve and the lower guide sleeve are all fixed on the left side of the winding seat. The pushing hydraulic cylinder, the upper guide rod and the lower guide rod are respectively inserted into the upper guide sleeve, the middle guide sleeve and the lower guide sleeve, and the pushing hydraulic cylinder, the upper guide rod and the lower guide rod are in clearance fit with the upper guide sleeve, the middle guide sleeve and the lower guide sleeve respectively. The front ends of the upper guide rod and the lower guide rod are respectively fixed to the pushing plate.

[0008] Preferably, the pushing mechanism further includes a connecting base plate. The front ends of the upper guide rod and the lower guide rod are fixed on the rear side surface of the connecting base plate, and the pushing plate is detachably fixed on the front side surface of the connecting base plate. The winding shaft is a telescopic roller.

[0009] Preferably, it further includes a winding and rectifying device. The winding and rectifying device includes a second hydraulic cylinder, an arc rod, a crank arm, a bracket and a plurality of separating sheets. The cylinder body of the second hydraulic cylinder is hinged on the left side surface of the winding base, one end of the arc rod is hinged to the free end of the telescopic rod of the second hydraulic cylinder, and the other end is fixed to the rear side of the crank arm. The bracket is fixed on the top surface of the winding base, the rear side of the crank arm is rotatably connected to the bracket, and a plurality of separating sheets are arranged at intervals on the front side of the crank arm. The separating sheets can be inserted into the gaps of the cut steel coils, and the axial direction of the separating sheets is consistent with the axial direction of the steel coils.

[0010] The technical solution of the present invention has the following beneficial effects:

[0011] In the present invention, the steel strip coil is pushed off the winding shaft by the pushing mechanism and falls onto the trolley, completing the lateral removal of the steel strip coil. The trolley can be lifted and lowered. When the steel strip coil falls onto the trolley, the trolley can be pushed to the blanking place, and then the trolley is lowered to a height close to the ground. Then, the worker can easily carry the steel strip coil to the blanking place, completing the longitudinal downward movement of the steel strip coil, greatly reducing the labor intensity of the worker and avoiding harm to the physical health of the worker. In addition, the blanking efficiency is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] The present utility model provides a steel strip shearing and slitting blanking device, including a pushing mechanism 1 and a trolley 2 arranged along the X-axis direction. The pushing mechanism 1 is fixed on the left side of the rewinding seat 3, and the trolley 2 is located in front of the rewinding seat 3. The trolley 2 can move bidirectionally along the X-axis and can be lifted and lowered.

[0021] Basic usage method of the utility model:

[0022] S1: In the initial state, the trolley 2 is located at the front end of the winding shaft 4, and the height of the trolley 2 is relatively high;

[0023] S2: After the steel materials to be sheared and slit are wound up, the worker starts the pusher mechanism 1. The actuator of the pusher mechanism 1 pushes along the X-axis towards the steel strip coil 6 (i.e., the axial direction of the steel strip coil 6), and pushes the steel strip coil 6 off the winding shaft 4 and exactly into the trolley 2;

[0024] S3: Push the trolley 2 to the place where blanking is required, and then the worker presses the lowering button of the trolley 2. The trolley 2 is lowered to a height close to the ground, and the worker can easily carry the steel strip coil 6 from the trolley 2 to the ground where the product is placed;

[0025] S4: Raise the trolley 2 to its original height position and push it back to the front end of the winding shaft 4 again.

[0026] S5: Repeat the steps of S2 - S4.

[0027] Specifically, the trolley 2 includes a tray 21, a chassis 22, a scissor-type support rod 23, a first hydraulic cylinder 24, and rollers 25. Rollers 25 are provided under the chassis, a scissor-type support rod 23 is provided above the chassis, the cylinder body of the first hydraulic cylinder 24 is fixed on the chassis 22 to drive the scissor-type support rod 23 to expand and contract, and the top of the scissor-type support rod 23 is fixed with the tray 21.

[0028] The tray 21 is used to place the steel strip coil 6 and can prevent the steel strip coil 6 from rolling and falling on the trolley 2. The rollers 25 enable the entire lifting trolley 2 to move. The raising and lowering of the trolley 2 are mainly carried out by respectively controlling the oil inlet and oil outlet of the first hydraulic cylinder 24.

[0029] Specifically, the pusher mechanism 1 includes a pusher hydraulic cylinder 11, an upper guide rod 12, a lower guide rod 13, a pusher plate 14, an upper guide sleeve 15, a middle guide sleeve 16, and a lower guide sleeve 17. The upper guide sleeve 15, the middle guide sleeve 16, and the lower guide sleeve 17 are all fixed on the left side surface of the winding seat 3. The pusher hydraulic cylinder 11, the upper guide rod 12, and the lower guide rod 13 respectively penetrate into the upper guide sleeve 15, the middle guide sleeve 16, and the lower guide sleeve 17. The pusher hydraulic cylinder 11, the upper guide rod 12, and the lower guide rod 13 are respectively in clearance fit with the upper guide sleeve 15, the middle guide sleeve 16, and the lower guide sleeve 17. The front ends of the upper guide rod 12 and the lower guide rod 13 are respectively fixed to the pusher plate 14.

[0030] The pusher mechanism 1 is mainly driven by the pusher hydraulic cylinder 11 for pushing and pulling. When pushing is required, the pusher hydraulic cylinder 11 is started. After the telescopic rod of the pusher hydraulic cylinder 11 extends, the pusher plate 14 is moved towards the steel strip coil 6. After the pusher plate 14 touches the steel strip coil 6, it pushes the steel strip coil 6 to move, thus pushing the steel strip coil 6 off the take-up reel 4. The mutual cooperation of the upper guide rod 12 and the upper guide sleeve 15, and the mutual cooperation of the lower guide rod 13 and the lower guide sleeve 17 provide guidance for the telescopic movement of the telescopic rod of the pusher hydraulic cylinder 11, preventing the telescopic rod of the hydraulic cylinder from deviating greatly during the forward movement, and ensuring that the pusher plate 14 can push the steel strip coil 6 smoothly.

[0031] Since the pusher hydraulic cylinder 11 penetrates into the middle guide sleeve 16 and there is a clearance fit between the pusher hydraulic cylinder 11 and the middle guide sleeve 16, the pusher hydraulic cylinder 11 can swing left and right within a certain range and degree in the middle guide sleeve 16, thus preventing, during the forward movement of the telescopic rod of the pusher hydraulic cylinder 11, due to the uneven force on the pusher plate 14, the force being concentrated and conducted in the reverse direction to the pusher hydraulic cylinder 11, causing damage such as oil leakage in the pusher hydraulic cylinder 11.

[0032] Since the steel strips to be manufactured have many specifications in length, the wide-width steel strip coils 6 also have many specifications in inner diameter value and outer diameter value. To avoid interference between the pusher plate 14 and the take-up reel 4, the pusher plate 14 is a semi-circular ring, and the take-up reel 4 can be located in the channel of the semi-circular ring. And since the steel strip coils 6 to be slit have many specifications in inner diameter value and outer diameter value, the diameter of the channel also needs to be adapted to the inner diameter value of the steel strip coil 6. Generally, the diameter of the channel should be greater than or equal to the inner diameter value of the steel strip coil 6 to ensure that the steel strip coil 6 can be pushed. Therefore, the pusher plate 14 needs to be replaced frequently. So the pusher mechanism 1 also includes a connecting bottom plate 18. The front ends of the upper guide rod 12 and the lower guide rod 13 are fixed on the rear side surface of the connecting bottom plate 18, and the pusher plate 14 is detachably fixed on the front side surface of the connecting bottom plate 18. The take-up reel 4 is a expandable and contractible roller. The diameter of the take-up reel 4 can be adjusted to wind the steel strip coils 6 with different inner diameter requirements.

[0033] When the pusher plate needs to be replaced, the existing pusher plate 14 is directly detached from the connecting bottom plate 18, and then another pusher plate of a different specification is installed on the connecting bottom plate 18.

[0034] To avoid the mutual influence of the steel strips after shearing and slitting on the winding work, the present utility model also provides a winding and rectifying device 5.

[0035] The coiling and rectifying device 5 includes a second hydraulic cylinder 51, an arc-shaped rod 52, a crank arm 53, a bracket 54 and a plurality of partition plates 55. The cylinder body of the second hydraulic cylinder 51 is hinged on the left side surface of the coiling seat 3. One end of the arc-shaped rod 52 is hinged to the free end of the telescopic rod of the second hydraulic cylinder 51, and the other end is fixed to the rear side of the crank arm 53. The bracket 54 is fixed on the top surface of the coiling seat 3. The rear side of the crank arm 53 is rotatably connected to the bracket 54. A plurality of partition plates 55 are arranged at intervals on the front side of the crank arm 53. The partition plates 55 can be inserted into the gaps of the cut steel coils. The axial direction of the partition plates 55 is the same as the axial direction of the steel coils. The partition plates 55 can limit adjacent steel strips to prevent adjacent steel strips from affecting each other during coiling. When it is necessary to coil the steel strip after shearing and slitting, after pressing the shortening control button of the telescopic rod of the second hydraulic cylinder 51, the telescopic rod of the second hydraulic cylinder 51 shortens, and the crank arm 53 rotates towards the direction close to the coiling shaft 4. Finally, the partition plates 55 touch the coiling shaft 4, and then the steel strip is coiled. After the coiling is completed, the telescopic rod of the second hydraulic cylinder 51 is extended, and the crank arm 53 rotates away from the coiling shaft 4, so that the partition plates 55 leave the coiling shaft 4, so as to facilitate the pusher mechanism 1 to push the material.

[0036] Obviously, the above embodiments are merely examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the creative utility model.
