Description

Technical Field

[0001] This utility model relates to the technical field of cold-rolled coil processing equipment, and in particular to a fixed-length automatic cutting and shearing equipment for cold-rolled coils. Background Technology

[0002] Cold-rolled coils, as an important industrial raw material, typically need to be cut into sheets of specific lengths according to process requirements before being used in subsequent manufacturing. Automated shearing equipment can automatically feed, cut to length, and shear the coils, greatly improving production efficiency.

[0003] In the fixed-length shearing process of cold-rolled coils, a crucial step to ensure the accuracy of the shearing dimensions is to quickly and securely fix the coil after it has been conveyed to the predetermined length using a clamping mechanism. The stability and reliability of the clamping directly determine the dimensional accuracy of the final product.

[0004] Existing shearing equipment mostly uses cylinders or hydraulic cylinders to directly drive the clamping blocks or clamping plates to achieve clamping. However, the stability and uniformity of the clamping force in this direct-drive method depend to some extent on the stability of the driving source pressure and the flatness of the clamping body itself. When the coiled plate has slight thickness unevenness or surface unevenness, the directly applied pressure may not be able to ensure uniform force distribution across the entire clamping surface, easily causing the coiled plate to produce imperceptible micro-displacement or warping when the shearing blade applies a huge shearing force. The accumulation of these micro-displacements will directly lead to length errors in the final sheared sheet material, failing to meet the requirements of high-precision machining.

[0005] Therefore, this utility model proposes an automatic cutting and shearing device for fixed length cold-rolled coils to overcome the shortcomings of the prior art. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figures 1-5This utility model provides an automatic cutting and shearing device for fixed length cold-rolled coils, which aims to solve the problems in the prior art where the clamping force of the clamping mechanism is unstable due to structural fit or transmission problems, thus affecting the cutting accuracy, and the contaminants on the surface of the coil affect the quality of the finished product.

[0029] Specifically, it includes a base 1 and a support frame 3 fixedly connected to the base 1. The base 1 serves as the mounting base for the entire device, providing stable support for the device, while the support frame 3 is used to centrally install and support subsequent working components such as the clamping assembly 5, cleaning assembly 6, and cutting blade 7, forming the main frame of the device.

[0030] It also includes a clamping assembly 5, which includes a fixed frame 509 and a guide plate 512. The fixed frame 509 and the guide plate 512 are both fixedly connected to the support frame 3, serving as the mounting base for the clamping assembly 5. The guide plate 512 provides a precise motion guide for the subsequent sliding components.

[0031] The core power source of the clamping assembly 5 is the electric push rod 510. The electric push rod 510 is installed in the internal space of the fixed frame 509, and the bottom end of the electric push rod 510 is rotatably connected to the fixed frame 509 through the rotating ring 502. This connection method allows the electric push rod 510 to swing slightly during operation to adapt to the movement trajectory of the transmission mechanism.

[0032] The internal transmission mechanism of the clamping assembly 5 includes a rotating shaft 508, a rotating plate 504, a first drive shaft 503, a drive plate 507, a sliding block 505, and a clamping plate 506. The extended end of the electric push rod 510 is connected to the rotating shaft 508 via a second drive shaft 511. When the electric push rod 510 extends or retracts, it pushes the rotating shaft 508 to rotate around its own axis. One end of the rotating shaft 508 is fixedly connected to the rotating plate 504, thereby converting the rotation of the rotating shaft 508 into the circumferential oscillation of the rotating plate 504. The moving plate 504 is connected to the drive plate 507 via the first drive shaft 503, which acts as a connecting rod. A sliding block 505 is fixedly connected to the drive plate 507. The sliding block 505 is slidably disposed in a pre-set groove in the guide plate 512. Finally, clamping plates 506 are fixedly connected to both sides of the sliding block 505. Through such a complete connecting rod and slider mechanism, the linear motion output by the electric push rod 510 is efficiently converted into the linear clamping or releasing action of the clamping plates 506 moving towards or away from each other. The structure is precise and the transmission is stable.

[0033] Meanwhile, the cutting blade 7 is mounted on the support frame 3 and located downstream of the clamping assembly 5. It is used to perform the final shearing action after the clamping assembly 5 has completed clamping and fixing the cold-rolled coil.

[0034] To efficiently remove dust, oil, and other impurities from the surface of the cold-rolled coil before shearing, preventing these impurities from affecting shearing quality and product precision, and reducing wear on the cutting blade 7, a cleaning component 6 is also included. The cleaning component 6 is mounted on the support frame 3, located upstream of the clamping component 5 in the feeding path. The cleaning component 6 includes a roller brush 601 for actively cleaning the coil surface, a feeding roller 605 for conveying the coil and providing power to the roller brush 601, and a motor 604 specifically for driving the feeding roller 605. The motor 604 is connected to the shaft end of the feeding roller 605 via a coupling or gearbox, providing the main force for conveying the coil. This achieves both cleaning and conveying... The feeding roller 605 transmits power to the roller brush 601 through a transmission system consisting of a belt 603 and pulleys 602. Specifically, pulleys 602 are fixedly installed on the shaft ends of the feeding roller 605 and the roller brush 601 respectively by key connection. The two pulleys 602 are wound and tensioned by an annular belt 603. When the motor 604 drives the feeding roller 605 to rotate, the power is transmitted synchronously to the roller brush 601 through the belt 603, so that it rotates at a linear speed matching the feeding speed. The bristles of the roller brush 601 are preferably made of high-density wear-resistant nylon material, which can effectively remove the attached substances without damaging the surface of the roll plate.

[0035] In order to smoothly transport the cut sheet material to the next station or collection area, the equipment also includes a feeding roller 2. The feeding roller 2 is set on the base 1 and located downstream of the cutting blade 7. The feeding roller 2 can be composed of multiple parallel non-powered rollers. When the cut sheet material falls due to gravity, it can fall smoothly onto the feeding roller 2 and slide smoothly along the roller surface by its own gravity or external thrust, thus realizing automatic feeding.

[0036] The cylinder 4 is connected to the side of the support frame 3 via a flange or clevis. The piston rod extension of the cylinder 4 can be connected to the drive mechanism of the cutting blade 7 according to design requirements to achieve rapid shearing action; or connected to an auxiliary pressing device to pre-flatten the coil before clamping.

[0037] To provide a more stable and reliable rotational support for the rotating shaft 508 and prevent radial displacement or vibration under long-term stress, the clamping assembly 5 also includes a fixing plate 501. The fixing plate 501 is fixed to the support frame 3 by bolts. The rotating shaft 508 is rotatably inserted into the shaft hole opened in the center of the fixing plate 501. A rolling bearing or a sliding bearing can be installed in the shaft hole to ensure the smooth rotation and centering accuracy of the rotating shaft 508, thereby improving the stability of the entire clamping transmission chain.

[0038] In order to convert the linear reciprocating motion of the electric push rod 510 into the reciprocating oscillation of the rotating shaft 508, the extended end of the electric push rod 510 is hinged to one end of the second drive shaft 511 by a pin, and the other end of the second drive shaft 511 is fixedly connected to the rotating shaft 508 by welding or spline. This "crank-slider" connection structure has reliable transmission.

[0039] In order to smoothly convert the circumferential oscillation of the rotating plate 504 into the reciprocating motion of the drive plate 507, the edge of the rotating plate 504 is rotatably connected to one end of the first drive shaft 503, and the other end of the first drive shaft 503 is rotatably connected to one side of the drive plate 507. The connection points are all made of pins or spherical bearings, so that the first drive shaft 503 acts like a connecting rod, smoothly transmitting the motion of the rotating plate 504 to the drive plate 507, ensuring that the final output motion to the sliding block 505 is smooth and without jamming.

[0040] Working principle: After the equipment is started, the motor 604 in the cleaning component 6 drives the feeding roller 605 to rotate. The feeding roller 605 pulls the cold-rolled coil from the outside into the equipment through friction. While the coil is being conveyed, the feeding roller 605 drives the roller brush 601 to rotate synchronously through the belt 603 and the pulley 602 to clean the upper surface of the coil entering the equipment in real time.

[0041] Once the coil is conveyed to the preset fixed length position, the clamping assembly 5 starts to work. The push rod of the electric push rod 510 installed in the fixed frame 509 extends and pushes the hinged second drive shaft 511, which in turn drives the rotating shaft 508 to rotate. The rotating plate 504, which is fixed to the rotating shaft 508, swings accordingly. The rotating plate 504 pushes the drive plate 507 through the first drive shaft 503. The drive plate 507 drives the fixedly connected sliding block 505 to make linear motion in the slide groove of the guide plate 512. Finally, the two clamping plates 506, which are fixed to the sliding block 505, move towards each other and firmly clamp and fix the cold-rolled coil from both sides.

[0042] After confirming that the coil is fully clamped, the cutting blade 7 mounted on the support frame 3 moves rapidly downward under the drive of its independent drive mechanism, such as a cylinder or another motor, to complete the shearing operation of the cold-rolled coil. After shearing, the cutting blade 7 returns to its original position. At the same time, the electric push rod 510 in the clamping assembly 5 retracts, driving the entire transmission mechanism to move in the opposite direction, causing the clamping plate 506 to release the coil. The cut sheet falls onto the unloading roller 2 below and is conveyed out. Thus, a complete fixed-length unloading shearing cycle ends, and the equipment is ready to enter the next working cycle.
