Embodiments of the first aspect
The following describes a large expansion and contraction range reel structure 100 according to an embodiment of the first aspect of the present application with reference to the drawings.
As shown in fig. 1, a large expansion and contraction range reel structure 100 according to an embodiment of the present application includes: the device comprises a main shaft 1, a sliding taper sleeve 2 and a fan-shaped arc plate 3.
Specifically, the main shaft 1 is used for carrying the sliding taper sleeve 2 and plays a role of support. The sliding taper sleeve 2 is slidably sleeved outside the main shaft 1, the sliding taper sleeve 2 is provided with a first sliding taper 21, the fan-shaped arc plate 3 is provided with a second sliding taper 31, and the sliding taper sleeve 2 and the fan-shaped arc plate 3 are slidably matched through the first sliding taper 21 and the second sliding taper 31. The expansion and contraction of the sector arc plate 3 are realized by changing the matching position of the first sliding cone 21 and the second sliding cone 31 (shown in fig. 2) through the sliding of the sliding cone sleeve 2 relative to the main shaft 1. An avoiding hole 22 for avoiding the second sliding cone 31 is formed in the side wall of the sliding cone sleeve 2, an avoiding groove 11 for avoiding the second sliding cone 31 is formed in the outer peripheral surface of the main shaft 1, and the second sliding cone 31 can penetrate through the avoiding hole 22 and enter the avoiding groove 11. The fan-shaped arc plate 3 has a contracted state and an expanded state, as shown in fig. 1, when the fan-shaped arc plate 3 is in the contracted state, the wedge-shaped top end of the second sliding cone 31 passes through the avoidance hole 22 and is accommodated in the avoidance groove 11; as shown in fig. 2, when the sector arc plate 3 is in the expanded state, the wedge-shaped tip of the second sliding cone 31 is separated from the escape groove 11.
According to the winding drum structure 100 with the large expansion and contraction range, due to the arrangement of the avoidance holes 22 and the avoidance grooves 11, the interference between the bottom of the fan-shaped arc plate 3 and the sliding taper sleeve 2 and the main shaft 1 when the diameter is reduced to the minimum is avoided, and the second sliding taper 31 is accommodated on the main shaft 1, so that the fan-shaped arc plate 3 has a smaller contraction diameter (the diameter is reduced, as shown in fig. 3); the connection position of the sliding taper sleeve 2 and the fan-shaped arc plate 3 is changed, so that the large-range expansion and contraction of the winding drum structure can be realized (as shown in figure 4), and the large-range expansion and contraction of the winding drum structure can be adapted to incoming steel coils with different inner ring diameters.
It should be noted that the wedge-shaped tip of the second sliding cone 31 here refers to the end of the second sliding cone 31 facing (close to) the main shaft 1.
As shown in FIG. 1, the large expansion and contraction range reel structure 100 further comprises a pull rod 4 and a positioning plate 5. The sliding taper sleeve 2 is slidably sleeved outside the main shaft 1, the pull rod 4 slidably penetrates through the main shaft 1, the pull rod 4 is used for being connected with a telescopic rod of an expansion and contraction oil cylinder 6 (shown in fig. 5), and the expansion and contraction oil cylinder 6 is used for driving the pull rod 4 to move relative to the main shaft 1; the pull rod 4 is connected with the sliding taper sleeve 2 through a connecting plate 41 (as shown in fig. 6), so that the pull rod 4 drives the sliding taper sleeve 2 to move relative to the main shaft 1. The positioning disc 5 is arranged on the circumferential surface of the main shaft 1 and is abutted against the shaft shoulder of the main shaft 1, and the sector arc plate 3 is connected with the positioning disc 5 in a sliding manner. The positioning disk 5 is provided with a strip-shaped hole 51 perpendicular to the axis of the main shaft 1, and the fan-shaped arc plate 3 is connected with the positioning disk 5 through a connecting piece penetrating through the strip-shaped hole 51. When the fan-shaped arc plate 3 expands and contracts under the action of the sliding taper sleeve 2, the fan-shaped arc plate 3 can move along the strip-shaped hole 51. Equivalently, when the pull rod 4 moves along the axial direction of the main shaft 1, the sliding taper sleeve 2 can move relative to the sector arc plate 3 along with the pull rod 4, so that the sector arc plate 3 moves relative to the positioning disc 5 along the direction perpendicular to the axial direction of the main shaft 1, and the expansion and contraction of the reel structure are realized.
According to some embodiments of the present application, as shown in fig. 7 and 8, the wedge angle α of the first sliding cone 21 and the second sliding cone 31 is 18-24 °, and compared with the conventional wedge angle of 12-15 °, the wedge angle α of the first sliding cone 21 and the second sliding cone 31 is increased, and under the same telescopic stroke of the collapsible cylinder 6, the drum structure of the present application has a larger collapsible range, and can adapt to steel coils with different inner diameter specifications.
As an optional mode of the application, the wedge angle α is 20 °, and when the wedge angle α is 20 °, the first sliding cone 21 and the second sliding cone 31 can have a longer contact length by matching with the design of the avoidance hole 22 and the avoidance groove 11, so that a larger expansion and contraction range of the reel structure is ensured.
According to some embodiments of the present application, the sliding cone sleeve 2 includes a plurality of sliding cone units 23 distributed at intervals along an axial direction thereof, each sliding cone unit 23 includes four first sliding cones 21 distributed at intervals along a circumferential direction of the sliding cone sleeve 2, each first sliding cone 21 is correspondingly provided with one avoidance hole 22, and the avoidance hole 22 is located at an end of the first sliding cone 21 facing the spindle 1. The fan-shaped arc plate 3 comprises a plurality of expansion and contraction units 32 matched with the sliding cone units 23, each expansion and contraction unit 32 comprises four second sliding cones 31 distributed along the circumferential direction of the fan-shaped arc plate 3, and when the fan-shaped arc plate 3 is matched with the sliding cone sleeve 2, the first sliding cone 21 is connected with the second sliding cone 31 in a sliding mode.
The four first sliding cones 21 are distributed at intervals along the circumferential direction and are constructed into a rectangular pyramid structure (as shown in fig. 6), so that the sliding cone sleeve 2 is in transmission fit with the fan-shaped arc plate 3; meanwhile, four sliding fit parts (the sliding connection part of the first sliding cone 21 and the second sliding cone 31) are arranged on one circle (along the circumferential direction of the main shaft 1), so that the transmission stability of the sliding cone sleeve 2 and the fan-shaped arc plate 3 is ensured. Each sliding cone unit 23 is provided with four first sliding cones 21, so that the connection stability of the sliding cone sleeve 2 and the fan-shaped arc plate 3 can be ensured, and the processing and the manufacturing are facilitated. If too many first sliding cones 21 are arranged in the circumferential direction, the connecting area of the first sliding cones 21 and the second sliding cones 31 cannot be ensured, the connecting strength of the first sliding cones 21 and the second sliding cones 31 is reduced, and meanwhile, the processing and the manufacturing are not convenient. If the first sliding cones 21 are arranged too little in the circumferential direction, the support strength of the fan-shaped arc plate 3 after expansion cannot be guaranteed, and the support points of the fan-shaped arc plate 3 and a steel coil are reduced.
In some embodiments of the present application, the plurality of sliding cone units 23 are integrally formed (as shown in fig. 7), which is equivalent to providing the plurality of first sliding cones 21 and the plurality of relief holes 22 on the sliding cone sleeve 2, so as to configure a plurality of sliding cone units 23. The sliding taper sleeve 2 is integrally formed in a casting mode, so that the sliding taper sleeve 2 is guaranteed to have certain rigidity, and the service life is prolonged.
In some embodiments of the present application, as shown in fig. 8, the sector arc plate 3 is provided with a transition groove 33, and when the sector arc plate 3 is in the contracted state, the wedge-shaped tip of the first sliding cone 21 is received in the transition groove 33. The wedge-shaped tip here refers to the end of the first sliding cone 21 remote from the spindle 1. The wedge-shaped length of the first sliding cone 21 determines the matching length of the first sliding cone 21 and the second sliding cone 31, that is, the expansion and contraction range of the fan-shaped arc plate 3 depends on the matching length of the first sliding cone 21 and the second sliding cone 31. When the arc segment plate 3 is in the contracted state, the wedge-shaped tip of the first sliding cone 21 is received in the transition groove 33, so that the arc segment plate 3 has a smaller outer diameter (i.e., a reduced diameter) than the case where the arc segment plate 3 cannot receive the wedge-shaped tip of the first sliding cone 21. The arrangement of the transition groove 33 ensures that the wedge-shaped top end of the first sliding cone 21 can be accommodated in the transition groove 33, so that the requirement that the drum structure has a smaller contraction diameter is met, and the expansion and contraction range of the drum structure is increased. Due to the fact that the drum structure has a small shrinkage diameter, the first sliding cone 21 and the second sliding cone 31 have a long matching length, when the first sliding cone 21 moves relative to the second sliding cone 31, the sliding cone sleeve 2 can move relative to the sector arc plate 3 along the axial direction for a long stroke, and therefore the expansion and shrinkage range of the drum structure is increased.
The fan-shaped arc plate 3 adopts an integral structure, is locally thinned (a transition groove 33), avoids the wedge-shaped top end of the first sliding cone 21, simultaneously protects the wedge-shaped contact surface (the contact surface of the first sliding cone 21 and the second sliding cone 31) and the circumferential surface of the main shaft 1, and avoids the blockage caused by the fact that the miscellaneous slag easily falls on the sliding surface (the wedge-shaped contact surface and the circumferential surface of the main shaft 1).
It should be noted that, the integral structure here means that the sector arc plate 3 is provided with a transition groove 33 between two adjacent second sliding cones 31 in the axial direction of the main shaft 1, or the end of each second sliding cone 31 corresponding to the first sliding cone 21, so as to avoid the existing structural form of breaking the sector arc plate, and the sector arc plate 3 is locally thinned through the transition groove 33, and avoids the wedge-shaped top end of the first sliding cone 21. The expansion and contraction principle of the sector arc plate 3 refers to the sector arc plate of the existing reel structure, and the application is not described in detail.
In some embodiments of the present application, when the arc segment plate 3 is in the contracted state, the outer diameter of the arc segment plate 3 is 485 mm. The minimum coil diameter equivalent to the winding drum structure is 485mm so as to adapt to a steel coil with the inner diameter of 508 mm.
The drum of the conventional uncoiler is designed to have a smaller expansion and contraction range, such as 475-515 mm, only 40mm expansion and contraction quantity, and only can meet a steel coil with the specification of 508mm inner diameter; after the diameter increasing plate with the thickness of 50mm is arranged on the fan-shaped plate, the expansion and contraction range is 575-615 mm, and the steel coil with the inner diameter specification of 610mm can only be met. Obviously, conventional unwinder reels have a small range of applications. Therefore, under the conditions of large specification change and multiple types of the inner diameter of some incoming steel coils, the winding drum structure of the conventional uncoiler obviously cannot meet the requirement.
According to some embodiments of the present application, the range of expansion and contraction of the sector arc plate 3 is 130 mm. The expansion and contraction range of the fan-shaped arc plate 3 ensures that the winding drum structure has a larger expansion and contraction range and can adapt to steel coils with different coil diameter specifications; because the minimum coil diameter of the reel structure is 485mm, the expansion and contraction range of the fan-shaped arc plate 3 is 130mm, and the maximum coil diameter of the fan-shaped arc plate 3 is 615mm, the reel structure can adapt to the steel coil with any specification within the coil diameter range of 508 and 610mm, and the application range is wide.
According to some embodiments of the present application, the first sliding cone 21 has a T-shaped cross section along the radial direction of the sliding cone sleeve 2, the second sliding cone 31 is provided with a dovetail groove matched with the first sliding cone 21, and the first sliding cone 21 is slidably disposed in the dovetail groove. Through the cooperation of T style of calligraphy structure and dovetail, guarantee that first smooth awl 21 and second smooth awl 31 have great area of contact, guarantee the stability of being connected of first smooth awl 21 and second smooth awl 31, can improve the life of first smooth awl 21 and second smooth awl 31.
In some embodiments of the present application, the second sliding cone 31 is provided with an oil hole 34, the oil hole 34 is provided on the outer surface of the sector arc plate 3 and penetrates through the sector arc plate 3, and the oil hole 34 is communicated with the dovetail groove. Through oil filler point 34, can provide lubricating oil or lubricating grease for the wedge contact surface of first sliding cone 21 and second sliding cone 31, be convenient for guarantee first sliding cone 21 and the slip flexibility of second sliding cone 31, reduce friction between the two, improve life.
The working principle of the large expansion and contraction range reel structure 100 of the first aspect of the present application is:
when the steel coil is suitable for a steel coil with a small coil diameter (the steel coil with the coil diameter of 508 mm), the fan-shaped arc plate 3 is in a contraction state, and the second sliding cone 31 is accommodated in the avoidance groove 11, so that the fan-shaped arc plate 3 has a smaller outer diameter; when the steel coil expanding device is suitable for a steel coil with a larger coil diameter, the tension rod 4 is pulled through the expanding and contracting oil cylinder 6 so that the sliding taper sleeve 2 moves relative to the main shaft 1, and the fan-shaped arc plate 3 is expanded through the sliding fit of the first sliding taper 21 and the second sliding taper 31 so that the fan-shaped arc plate 3 supports the inner diameter of the steel coil.
The large expansion and contraction range reel structure 100 of the embodiment of the first aspect of the present application has the following beneficial effects:
a hole (an avoidance hole 22) is formed in the sliding taper sleeve 2 and an avoidance groove 11 is formed in the main shaft 1 so as to avoid the lower limit (the wedge-shaped top end of the second sliding taper 31) when the fan-shaped arc plate 3 contracts, and the winding drum is ensured to have a smaller contraction diameter; in order to meet the large expansion and contraction range of the winding drum, the angle of the contact surface of the sliding cone and the fan-shaped plate is increased to 18-24 degrees, and the strength and rigidity performance requirements of the winding drum are met, and the large expansion and contraction of the winding drum structure can be realized by combining the connection position change of the sliding cone sleeve 2 and the fan-shaped arc plate 3 so as to adapt to incoming steel coils with different inner ring diameters.
