Description

Technical Field

[0001] The utility model belongs to the technical field of rolling mill engineering equipment and relates to a coiling roll parallelism adjustment structure of a belt coiler. Background Art

[0002] The strip steel outlet speed of a modern cold tandem mill reaches 40 m / s. In order to improve the productivity of the rolling mill, shorten the auxiliary operation time and adapt to a higher biting speed, the mandrels of coiling machines in cold tandem mill units do not adopt jaws but use coilers to help wind the strip steel around the mandrel. A horizontally moving belt coiler is usually adopted. The belt coiler relies on the threading speed and winds the initial steel coil around the mandrel of the coiling machine through the belt for 3 - 5 turns, and then the belt coiler retracts. The annular belt used in the current belt coiler needs to be integrally assembled in the frame body, so a slot needs to be opened on one side of the frame body or it is made into a corresponding split structure, and a connecting device is correspondingly provided. Generally, 6 - 8 coiling rolls arranged in two rows side by side are assembled on the belt coiler to play the functions of supporting the belt and coiling. These rolls must be parallel to each other during use to ensure uniform stress in the width direction of the strip when the belt hugs the mandrel shaft.

[0003] Therefore, the connection and adjustment device of the coiler frame body and the selection of the position or structure directly affect the parallelism of the coiling rolls. However, in the prior art, due to the incomplete same structure settings on both sides of the frame body, the coiling rolls have poor horizontality after assembly and cannot be adjusted, which directly affects the product quality. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a coiling roll parallelism adjustment structure of a belt coiler, which solves the problem that in the prior art, due to different structures on both sides of the frame body, the coiling rolls have poor horizontality after assembly and cannot be adjusted.

[0005] The technical solution adopted by the utility model is that for the coiling roll parallelism adjustment structure of the belt coiler, the frame body of the coiler is divided into two parts, which are connected into a whole. There are two connection components and a set of parallel adjustment mechanisms between the two parts. The structure of the parallel adjustment mechanism includes an upper support and a lower support. An adjusting bolt is hinged in the lower support through a pin shaft, and a fixing nut is provided for the pin shaft; the upper section of the adjusting bolt extends into the inner cavity of the upper support, and an adjusting nut is sleeved on the upper section of the adjusting bolt. A flat washer is arranged between the adjusting nut and the lower surface of the upper support.

[0006] The coiling roll parallelism adjustment structure of the belt coiler of the utility model is further characterized in that:

[0007] The upper support is welded to the lower side of the lower swing arm of the belt coiler equipment, and the lower support is welded to the upper part of the base of the belt coiler equipment.

[0008] The structure of the upper bracket is that the main body of the upper bracket includes two rectangular thick plates. A connecting column is fixedly connected at the upper front part between the two rectangular thick plates. The rear end faces of the two rectangular thick plates are fixed to the lower swing arm end of the belt coiling device, and all are fixed by welding.

[0009] The structure of the lower bracket is that the cross-section of the main body of the lower bracket is in an inverted "concave" shape with the opening facing outwards. A pin hole is penetrated between the two protruding edges of the lower bracket, and the pin hole is used for inserting a pin shaft; an ear end of an adjusting bolt is hinged on the pin shaft between the two protruding edges of the lower bracket.

[0010] The structure of the adjusting bolt is that the ear end of the adjusting bolt is flat. The ear hole of the adjusting bolt is hinged with the pin shaft, and the screw end of the adjusting bolt extends upwards between the two rectangular thick plates of the upper bracket.

[0011] The structure of the pin shaft is that the large head end of the pin shaft is flat. The hinged rod of the pin shaft passes through the pin hole of the lower bracket, and the outer section of the hinged rod of the pin shaft is set as a threaded section for installing a fixing nut.

[0012] The beneficial effect of the present utility model is that since a hydraulic cylinder cannot be added on one side of the frame body, a connecting device is added at the lower part of the frame body. This device can be opened when disassembling and assembling the belt and closed when the belt is installed, and the upward length is adjusted by bolts and nuts to tighten the frame body, thereby finely adjusting the height of the coiling roller, thus solving the problem that the coiling roller has a poor levelness after assembly and cannot be adjusted due to different structures on both sides of the frame body. The structure is simple and reliable. Description of the Drawings

Specific embodiments

[0029] The present utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] The "upper, lower, left, and right" directions involved in the following text are all intuitive descriptions for the corresponding drawings and do not limit the installation positions of the components of the device structure. The actual installation positions can be inferred accordingly.

[0031] As Figure 1As shown in the figure, the existing coiler is assembled from components such as a swing hydraulic cylinder 14, a frame 15, a belt telescopic cylinder 16, a lower swing arm 17, a coiling roll 18, and a moving hydraulic cylinder 19. When the coiler starts coiling the strip steel, the belt coiler is standby at a distance of 2 - 4 meters from the coiler. The lower swing arm 17 is in the open position, the belt is slightly open and drooping. During operation, the frame is pushed by the moving hydraulic cylinder 19 and travels on the track close to the reel side of the coiler. There is a proximity switch to send a signal to notify whether the action is in place. Subsequently, the swing hydraulic cylinder 14 acts to make the coiling roll 18 on the lower swing arm 17 hold the reel tightly, and the belt wraps around the reel. After coiling 3 - 5 turns, the head of the strip steel is wrapped by the strip steel. When withdrawing, the entire belt first makes the lower swing arm 17 open through the drive of the swing hydraulic cylinder 14, and then the coiler is pushed away from the coiler by the moving hydraulic cylinder 19 and moves out.

[0032] As Figure 2 shown, the frame 15 of the existing coiler is divided into two parts, which are connected as a whole. There are two connecting components 11 and one adjusting mechanism 10 between the two parts. Since the adjusting mechanism 10 is far from the head of the coiler, after actual assembly, the coiling rolls 18 at the head of the coiler are not parallel to each other, with a difference of 0.2 - 0.3 mm. The position of the coiling roll 18 on the frame 15 is fixed by itself and cannot be adjusted.

[0033] Referring to Figure 3 、 Figure 4 , the structure of the present invention is that on the basis of the existing structure, a set of parallel adjusting mechanisms 12 is added. The structure is similar to the existing adjusting mechanism 10, but because there is a hydraulic cylinder installed on the lower right side and there is a position interference and it cannot be directly installed, the structure of the adjusting mechanism 10 is appropriately modified to obtain the parallel adjusting mechanism 12.

[0034] Referring to Figure 5 、 Figure 6 , the structure of the parallel adjusting mechanism 12 of the present invention includes an upper bracket 1 and a lower bracket 5. In the lower bracket 5, an adjusting bolt 4 is hinged through a pin shaft 6, and a fixing nut 7 is provided for the pin shaft 6; the upper section of the adjusting bolt 4 extends into the inner cavity of the upper bracket 1, and an adjusting nut 3 is sleeved on the upper section of the adjusting bolt 4. A flat washer 2 is provided between the adjusting nut 3 and the lower surface of the upper bracket 1.

[0035] Referring to Figure 7 、 Figure 8 , the structure of the upper bracket 1 is that the main body of the upper bracket 1 includes two rectangular thick plates 13. A connecting column 9 is fixedly connected at the front upper part between the two rectangular thick plates 13. The rear end faces of the two rectangular thick plates 13 are fixed at the lower swing arm end of the belt coiler equipment, and all are fixed by welding. The lower end face can be extended outwards to facilitate the adjusting bolt 4 and the adjusting nut 3 to jack upwards to finely adjust the levelness of the coiling roll.

[0036] Referring toFigure 9 , Figure 10 , Figure 11 , the structure of the lower bracket 5 is that the cross-section of the main body of the lower bracket 5 is in an inverted "concave" shape (the opening faces outward, which is convenient for the up-and-down flipping of the pin shaft 6, see Figure 11 ). A pin hole 8 is penetrated between the two protruding edges of the lower bracket 5, and the pin hole 8 is used for inserting the pin shaft 6; the lug end of the adjusting bolt 4 is hinged on the pin shaft 6 between the two protruding edges of the lower bracket 5.

[0037] Referring to Figure 12 , Figure 13 , the structure of the adjusting bolt 4 is that the lug end of the adjusting bolt 4 is flat, the lug hole of the adjusting bolt 4 is hinged with the pin shaft 6, and the screw end of the adjusting bolt 4 extends upward between the two rectangular thick plates 13 of the upper bracket 1.

[0038] Referring to Figure 14 , Figure 15 , the structure of the pin shaft 6 is that the big head end of the pin shaft 6 is flat, the hinged rod of the pin shaft 6 passes through the pin hole 8 of the lower bracket 5, and the outer section of the hinged rod of the pin shaft 6 is set as a threaded section for installing the fixing nut 7.

[0039] Referring to Figure 1 , Figure 3 , Figure 5 , the working principle of the parallel adjustment mechanism 12 of the present utility model is that the parallel adjustment mechanism 12 is installed at the lower swing arm end of the belt coiling assist device to realize the adjustment of the parallelism of the coiling roller. During actual implementation, one upper bracket 1 is fabricated and welded to the lower side edge near the coiling roller of the lower swing arm of the coiling assist device, and full welding treatment is performed at each joint with the lower swing arm; one flat washer 2 is fabricated; one adjusting nut 3 is fabricated; one adjusting bolt 4 is fabricated; one lower bracket 5 is fabricated; one pin shaft 6 is fabricated; one fixing nut 7 is fabricated.

[0040] Referring to Figure 4 , Figure 6 , the installation method of the parallel adjustment mechanism 12 of the present utility model is to weld the upper bracket 1 to the lower side of the lower swing arm 17 of the belt coiling assist device, weld the lower bracket 5 to the upper part of the base of the belt coiling assist device, then hinge and fix the adjusting bolt 4 to the lower bracket 5 through the pin shaft 6 and the fixing nut 7, install the flat washer 2 on the upper surface of the adjusting nut 3 to ensure good contact between the adjusting nut 3 and the upper bracket 1, and perform fine position adjustment through the adjusting nut 3 to meet the parallelism requirements of the coiling roller of the belt coiling assist device and other rollers, so as to ensure that the belt does not deviate during use.
