Description

Technical Field

[0001] The invention relates to the field of coilers, in particular to a double-jaw quick-change reel type coiler. Background Art

[0002] The coiler is an important main machine component in the slitting line finishing unit. Its function is to roll plates of different specifications into finished steel coils of set sizes through the reel. The main motor of the coiler transmits power to the reel through the gear box. The reel clamps the plate heads of several strips through the jaws to wind them into steel coils. The conventional slitting line finishing unit is divided into thin plate line and thick plate line. The thin plate line refers to the cold-rolled plate and silicon steel plate with a thickness range of 0.2-3mm, which are commonly used in home appliances, automobiles and other industries; the thick plate line refers to the cold-rolled and hot-rolled plate with a thickness range of 1-6mm, which are commonly used in steel distribution and other industries. The current market situation is that many steel distribution centers usually need to configure two production lines (thin plate line and thick plate line) in order to process 0.2-6mm plates. The investment cost is high and insufficient production capacity will cause waste of resources. Summary of the invention

[0006] Furthermore, the second top block inside the second jaw drives the second full-length jaw strip and the second fan-shaped plate to clamp and fix the thin steel plate, and a jaw disc spring is installed at the bottom of the second full-length jaw strip.

[0007] Furthermore, the ends of the second full-length jaw strip and the first full-length jaw strip are fixedly provided with serrated jaw strips, and the surfaces of the serrated jaw strips are serrated; the deformation amount of the jaw disc spring on the first full-length jaw strip is greater than the deformation amount of the jaw disc spring on the second full-length jaw strip.

[0008] Furthermore, the expansion and contraction of the first fan plate, the second fan plate and the third fan plate on the drum assembly are realized by the axial extension and retraction of the pull rod driven by the rotating cylinder, and the pull rod is connected to the copper wedge to drive the first top block and the second top block to move radially, and at the same time, the inclined surfaces on both sides of the first top block and the second top block simultaneously drive the first fan plate and the second fan plate to move radially.

DETAILED DESCRIPTION

[0017] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art may also adopt other alternatives to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the present invention.

[0018] Specific implementation method 1: Please refer to Figure 1-4The present invention provides a technical solution: a double-jaw quick-change reel-type winder, comprising a reel assembly 17, a first jaw 171 is provided on the upper part of the reel assembly 17, and a second jaw 172 is provided on the lower part of the reel assembly 17, and a thin steel plate 16 is inserted into the interior of the second jaw 172, and a thick steel plate 8 is inserted into the interior of the first jaw 171; a first sector plate 3, a second sector plate 9 and a third sector plate 15 are respectively installed on the circumferential outer side of the reel assembly 17, a first top block 4 is installed inside the first jaw 171, and a second top block 12 is installed inside the second jaw 172, and a first full-length jaw strip 5 is fixedly installed on the first top block 4, and a second full-length jaw strip 5 is fixedly installed on the second top block 12 The mouth strip 13, the bottom of the first top block 4 is installed with a copper bevel 11, and the bottom of the second top block 12 is installed with a copper bevel 11; a pull rod 7 is inserted in the middle of the reel assembly 17, and the end of the pull rod 7 is screwed and fixed to the copper bevel 11, and at the same time, an oblique key 25 and a connecting sleeve 26 are installed at the end of the pull rod 7 away from the copper bevel 11, and the pull rod 7 is fixed to the piston rod of the rotating cylinder 27 through the oblique key 25 and the connecting sleeve 26, and the end cover of the rotating cylinder 27 is screwed and fixed to the right end face of the reel assembly 17 through a connecting frame and a locking screw 28; a screw 1 is installed on the first fan-shaped plate 3, the second fan-shaped plate 9 and the third fan-shaped plate 15 through a nut 10, and a disc spring 2 is sleeved on the outer side of the bottom of the screw 1.

[0019] Working principle: The double jaw reel assembly 17 is realized by the following technical solutions: Two sets of jaw devices are arranged on a reel assembly 17: jaw 1 171 and jaw 2 172. The jaw 1 171 has a large opening stroke and is used to clamp a 3-6 mm thick steel plate 8. The first top block 4 drives the first full-length jaw strip 5 and the jaw surface of the first fan-shaped plate 3 to clamp the steel plate, and the clamping force is provided by the disc spring 6. The expansion and contraction stroke of the first top block 4 is greater than the expansion and contraction stroke of the first sector plate 3, so as to realize the opening and closing of the jaws, and the difference between the two is the opening size of the jaws; The expansion and contraction of the reel assembly 17 is achieved by the rotating oil cylinder 27 driving the pull rod 7 to achieve axial expansion and contraction. The pull rod 7 is connected to the copper bevel 11 to drive the first top block 4 and the second top block 12 to achieve radial movement. The inclined surfaces on both sides of the first top block 4 and the second top block 12 simultaneously drive the first sector plate 3 and the second sector plate 9 to move radially. When the rotating oil cylinder 27 contracts, the reel assembly 17 expands. When the rotating oil cylinder 27 extends, the first sector plate 3 is guided by the disc spring 2 through the screw 1 to achieve retraction. The driving mode of the second sector plate 9 and the third sector plate 15 is consistent with the above, and the reel assembly 17 contracts at this time. The opening stroke of the second jaw 172 is small, and it is used to clamp a thin steel plate 16 of 0.2-3 mm. The second top block 12 drives the second full-length jaw strip 13, the serrated jaw strip 14 and the jaw surface of the second fan-shaped plate 9 to clamp the steel plate, and the clamping force is also provided by the disc spring below it; The clamping force of the jaws required for thick plates is greater than that required for thin plates, so when the jaw 171 clamps a thick plate, the deformation of the disc spring 6 is greater than the deformation of the disc spring in the jaw 2 172, which can provide a large clamping force, which is conducive to preventing the clamping plate head from loosening during winding; The quick-change reel structure is realized through the following technical solutions: like Figure 3-4 As shown: the reel assembly 17 represents reels of various specifications, which are radially positioned by the guide key 18 on the tapered surface and the pyramid sleeve 22. The tapered surface can make it easier to disengage the main shaft part from the pyramid sleeve 22 when changing the reel, while ensuring the load of the reel; the guide key 18 can be set as a single key or a double key according to different models; The reel assembly 17 can slide axially in the pyramid sleeve 22: by removing the oblique key 25 installed at the rear end and the locking screw 28 fixing the reel spindle, the axial positioning of the reel can be released, and the reel to be replaced can be ejected with the help of the thrust of the rotating cylinder 27 in combination with the tooling, so as to achieve rapid reel replacement, and the effect is remarkable after on-site testing; the customer only needs 20 minutes to operate it with a remote control; The power of the reel is transmitted to the reel by the motor through the gear 21 and the pyramid sleeve 22. The front end of the cone sleeve 22 is installed with the first bearing 20 and the flange cover 19, and the rear end is installed with the second bearing 24. The pyramid sleeve 22 is positioned and installed on the transmission box through the front and rear bearings and the rear end nut. The connection and disconnection of the pulling and pushing forces of the reel assembly 17 and the rotating cylinder 27 are achieved through the connecting sleeve 26 and the inclined key 25 installed inside it. When the inclined key 25 is installed, the inclined key 25 is subjected to the pulling and pushing forces of the shear force transmitting cylinder. When the inclined key 25 is removed, the pull rod 7 inside the reel can slide out from the center hole of the connecting sleeve 26, thereby realizing the separation of the reel and the rotating cylinder 27.

[0020] The coiler is suitable for both thin plates with a thickness range of 0.2-3mm and thick plates with a thickness range of 3-6mm, including clamping and coiling of cold-rolled plates, hot-rolled plates, silicon steel plates, high-strength plates, etc., and can process a wide range of plate thickness; Two sets of jaw devices are provided on the reel assembly 17 of the coiler, including jaw 1 171 and jaw 2 172. The jaw 2 172 is used to clamp the thin steel plate 16, whose thickness is between 0.2-3mm, and the jaw 1 171 is used to clamp the thick steel plate 8, whose thickness is between 3-6mm. Thus, one reel assembly 17 can meet the requirements of clamping both thin plates and thick plates, saving costs and improving production efficiency. In view of the fact that the existing reel assembly 17 of the coiler cannot meet the requirements of clamping thin plates and thick plates at the same time, a new type of reel assembly 17 with a double jaw structure is provided, in which one set of jaws is used to clamp thin plates, and the other set of jaws is used to clamp thick plates, thereby increasing the applicable range of plate thickness and greatly saving the investment cost of production lines for customers; originally two production lines are invested, but now only one is needed; at the same time, a common problem in the industry is also solved: when a reel assembly 17 with only one jaw clamps a thick plate and then clamps a thin plate with a large number of strips after being slit by a slitting machine, several strips are often not clamped tightly and become loose; By adding a pyramid sleeve 22 and a quick-change mechanism, the reel assembly 17 of the winder is separated from the box body, so that the reel assembly 17 can be quickly separated from the box body to achieve the purpose of quick replacement of the reel assembly 17; actual measurements on site with a remote control show that the original time for replacing the reel assembly 17 is shortened from several hours to about 20 minutes; the problem that the original reel assembly 17 is difficult to disassemble and assemble and inconvenient for maintenance is solved.

[0021] Specific embodiment 2: This embodiment is a further limitation of specific embodiment 1, the opening stroke of jaw 171 is greater than the opening stroke of jaw 2 172, and the first top block 4 inside jaw 171 drives the first full-length jaw strip 5 and the first fan-shaped plate 3 to clamp and fix the thick steel plate 8, and at the same time, a jaw disc spring 6 is installed at the bottom of the first full-length jaw strip 5; the expansion and contraction stroke of the first top block 4 is greater than the expansion and contraction stroke of the first fan-shaped plate 3.
