Description

Technical Field

[0001] The utility model relates to the field of aluminum processing, in particular to a movable supporting device and a coiling machine. Background Art

[0002] In the rolling, finishing, slitting and other processes of aluminum sheet and strip, there are coilers at both ends of the machine train. The coilers are mainly used to roll aluminum sheet and strip into coils. The coilers are equipped with reels for rolling aluminum sheet and strip. The reels are driven by power equipment to complete the winding of aluminum sheet and strip. At present, one end of the reel of the coiler is connected to the main body of the coiler, and the other end is suspended. After the winding work is completed, the rolled aluminum sheet and strip is taken away from the free end of the reel, and then the next winding work is carried out.

[0003] In order to ensure the rigidity of the coiler and improve the stability of the reel when it rotates at high speed, a movable support is usually designed at the free end of the reel in the prior art. The current movable support is generally an elephant trunk cantilever movable support. When the aluminum sheet and strip are wound on the reel, the elephant trunk cantilever movable support provides support for the reel; after the aluminum sheet and strip are wound, the elephant trunk cantilever movable support is away from the free end of the reel to facilitate the removal of the aluminum sheet and strip from the reel. However, in the actual winding process, the elephant trunk cantilever movable support is subjected to a huge tipping torque during operation. After a long time, it is easy to deform due to fatigue and the like and cannot provide good support for the reel. When the free end of the reel cannot obtain stable auxiliary support, it is easy to cause the overall rigidity and precision of the reel of the coiler to deteriorate, which ultimately affects the accuracy of the winding of the aluminum sheet and strip. Utility Model Content

[0004] The utility model aims to provide a movable support device and a coiler to eliminate the problem of tipping moment suffered by the trunk-type cantilever movable support in the prior art when working, and to make the coiler more rigid and stable as a whole while providing support for the reel.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a movable support device, including a base, on which two support arms are rotatably connected, and the free ends of the two support arms are slidably connected to support units, and when the free ends of the two support arms are rotated to abut against each other and form a triangular structure with the base, the support units on the two support arms slide close to form a support space for supporting the roller.

[0006] The principle and effect of this scheme are as follows: in actual application, since the two support arms are rotatably connected to the base, therefore, before the reel of the coiler rotates to reel up the aluminum plate and strip in the prior art, the two support arms rotate relative to the base and the free ends of the two support arms rotate to abut each other. At this time, the base and the two support arms form a triangular structure and can withstand a larger load in the vertical direction, thereby being able to provide stable support for the reel; then the support unit at the free end of the support arm is driven to slide, so that the two support units are close to each other and form a support space for supporting the reel in the prior art, and the support space is used to assist in supporting the free end of the reel, thereby avoiding that one end of the reel is in a suspended state when the reel is reeling up the aluminum strip, so that the free end of the reel always obtains stable auxiliary support during work, thereby ensuring the accuracy of the reeling of the aluminum plate and strip, and effectively extending the service life of the reel, thereby saving costs.

[0007] In addition, in the present application, after completing a winding action, the two support units first slide relative to the corresponding support arms respectively, so that the two support units move away from each other, and then the support arms are rotated, so that the two support arms gradually rotate to a state of moving away from each other. At this time, since the two support units have moved away from each other, during the process of the two support arms rotating to move away from each other, the two support units will not interfere with the rollers in the prior art, thereby ensuring the safety of the equipment. Finally, when the two support arms rotate to a state of moving away from each other, the obstruction of the support arms and the support units to the free end of the roller is eliminated, and the rolled aluminum sheet strip can be removed from the roller along the axial direction of the roller, and then the next winding work can be completed.

[0008] Preferably, as an improvement, the support unit comprises a support roller, a sliding seat and a driving member, the support roller is rotatably connected to the sliding seat, and the driving member is used to drive the sliding seat to slide along the length direction of the support arm.

[0009] In practical applications, the support roller is rotatably connected to the sliding seat so that the two support rollers surround the support space. As a result, when the winding roller rotates during use, the two support rollers can be driven to rotate, thereby preventing the free end of the winding roller from being quickly worn out, and effectively protecting the free end of the corresponding winding roller. In addition, in the present solution, a driving member is provided to drive the sliding seat to slide along the length direction of the support arm to achieve automatic drive, so that the entire device has a higher degree of automation and the winding is more efficient and stable.

[0010] Preferably, as an improvement, the driving member includes a driver, a driving wedge and an elastic reset member, the driver is connected to the support arm, the driving wedge is connected to the driver, one side of the driving wedge cooperates with the wedge surface of the support arm, and the other side abuts against the sliding seat, and the sliding seat is located between the driving wedge and the elastic reset member.

[0011] In the present solution, relying on the matching relationship between the driving wedge block and the wedge surface of the support arm, when the driving wedge block is pushed by the driver to slide relative to the support arm, the driving wedge block can push the sliding seat to slide relative to the support arm under the action of the wedge surface matching, thereby driving the two support rollers to approach each other and form a support space, and in this process the elastic reset part is compressed and accumulates force; when the winding is completed, the driver pushes the driving wedge block to move in the opposite direction, at this time, under the action of the elastic force of the elastic reset part, the two sliding seats automatically move away, thereby making the two support rollers move away from each other and no longer support the winding roller. The entire driving structure is simple, easy to operate and can provide stable support for the sliding seat and the support roller.

[0012] Preferably, as an improvement, a fixed wedge is fixedly connected to the support arm, and the wedge surfaces of the driving wedge and the fixed wedge are matched.

[0013] In this solution, by fixing the fixed wedge block on the support arm, on the one hand, the fixed wedge block can be manufactured separately to avoid directly processing the wedge surface on the support arm, thereby effectively reducing the processing cost; on the other hand, when the wedge surface of the fixed wedge block is worn, the fixed wedge block can be easily replaced.

[0014] Preferably, as an improvement, a mounting groove is provided at the free end of the support arm, and the sliding seat and the driving member are both located in the mounting groove.

[0015] In this solution, by providing the installation groove, the sliding seat and the driving member can be installed and connected more conveniently and stably, reducing the interference of external objects on the sliding seat and the driving member, so that the device can work more stably.

[0016] Preferably, as an improvement, the number of the sliding seats is two and the two sliding seats are respectively connected to the two ends of the supporting roller, and the number of the driving members is two and the two driving members are respectively arranged in one-to-one cooperation with the two sliding seats.

[0017] In this solution, sliding seats and driving members are provided at both ends of the support roller, so that when the support roller is driven to slide relative to the support arm, the two ends of the support roller can slide synchronously and stably, thereby improving the stability of the support roller during the position adjustment process, and both ends of the support roller are effectively supported by the sliding seat, so that the support roller can provide more stable auxiliary support for the free end of the winding roller.

[0018] Preferably, as an improvement, the two driving members share one driver.

[0019] In this solution, the driver for driving the two sliding seats is set to be the same, which not only reduces the number of drivers used, thereby effectively reducing costs, but also uses one driver to drive the two sliding seats to slide, so that the two sliding seats can slide synchronously, effectively ensuring the consistency of sliding at both ends of the support roller, thereby allowing the support roller to slide stably and accurately.

[0020] Preferably, as an improvement, the driver is a hydraulic cylinder.

[0021] In this solution, a hydraulic cylinder is used as a driving component. The hydraulic cylinder has a large driving force and works very stably. After driving the support roller to slide, it can provide stable support for the sliding seat and the support roller, thereby providing stable supporting force for the support roller during the winding process, so that the support roller can provide stable auxiliary support for the free end of the reel.

[0022] Preferably, a limiting member for cooperating with the support arm is fixedly connected to the base, and when the free ends of the two support arms rotate to a state of being away from each other, the support arm and the limiting member abut against each other.

[0023] In this solution, by fixing a limit piece on the base, when the reel completes the winding of the aluminum plate strip and the two support arms rotate to a state of moving away from each other, the limit piece can be used to block and support the support arms, preventing the support arms from becoming unstable and tipping over after rotating to the state of moving away from each other, thereby improving the safety of the entire equipment.

[0024] In order to achieve the above-mentioned purpose, the utility model also adopts the following technical solution: a coiler, comprising any movable supporting device as described above. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following is further described in detail through specific implementation methods:

[0030] Example 1

[0031] Embodiment 1 is basically as attached Figure 1 As shown: a movable support device includes a base 1, and two support arms 2 are rotatably connected to the base 1 through a pin shaft. The base 1 can be two separate bases, that is, one base 1 has one support arm 2, and the base 1 can also be integrated, that is, one base 1 has two supports. As an example, this embodiment shows a design of one base 1 with one support arm 2, and the attached Figure 1 A front view of the left support arm 2 and a partial cross-sectional view of the right support arm 2 are shown to facilitate easy understanding by those skilled in the art.

[0032] In this embodiment, a power device is provided to drive the support arm 2 to rotate relative to the base 1, and the required power device may be of various types, including but not limited to one of an electric cylinder, a pneumatic cylinder, and a hydraulic cylinder. As an example, in this embodiment, a rotary hydraulic cylinder 3 is used to drive the support arm 2 to rotate, and in order to improve the stability of the rotation of the support arm 2, two rotary hydraulic cylinders 3 may be provided on each support arm 2. In actual application, when the support arm 2 needs to be away from the reel 4 in the prior art, the piston rod of the rotary hydraulic cylinder 3 is pushed out, driving the support arm 2 to rotate in a direction away from the reel 4, and when the support arm 2 needs to be close to the reel 4, the piston rod of the rotary hydraulic cylinder 3 is retracted, driving the support arm 2 to rotate in a direction close to the reel 4.

[0033] like Figure 1 As shown, the two support arms 2 are rotatably connected to the base 1, and the free ends of the two support arms 2 are slidably connected with the support units along the length direction of the support arms 2. When the free ends of the two support arms 2 are rotated to approach each other and abut against each other to form a triangle shape (i.e. Figure 1 In the state shown in the figure), the two support units are brought closer to each other by sliding the two support units, so that the two support units enclose a support space for supporting the free end of the roller in the prior art.

[0034] Combination Figure 1 and Figure 2 The support unit in this embodiment includes a support roller 5, a sliding seat 6 and a driving member, wherein a mounting groove is opened at the free end of the support arm 2, and the sliding seat 6 is slidably connected in the mounting groove along the length direction of the support arm 2. The support roller 5 is rotatably connected to the sliding seat 6 through a bearing. In order to make the rotation of the support roller 5 more stable, in this embodiment, sliding seats 6 are correspondingly arranged at both ends of the support roller 5, that is, the number of sliding seats 6 is two, and correspondingly, the number of driving members is also two and is arranged one-to-one with the two sliding seats 6.

[0035] Specifically, as a means of implementation, the driving member includes a driver 7, a driving wedge 8 and an elastic reset member. The driver 7 is connected to the installation groove, and in this embodiment, two driving members that cooperate with the same support roller 5 share one driver 7, thereby effectively simplifying the structure and reducing the overall cost of the device. The driver 7 in this embodiment adopts a hydraulic cylinder, which has two output shafts, and the two output shafts are fixedly connected to the two driving wedges 8 respectively. The hydraulic cylinder is suspended in the installation groove; at the same time, a fixed wedge 9 is fixedly connected in the installation groove, and the wedge surfaces between the driving wedge 8 and the fixed wedge 9 are matched. A receiving groove is opened in the installation groove, and the elastic reset member includes a reset spring 10 installed in the receiving groove. One side of the sliding seat 6 is against the reset spring 10, and the other side is against the driving wedge 8. The driver 7 can simultaneously push the two driving wedges 8 away from each other. Under the cooperation of the wedge surfaces of the driving wedge 8 and the fixed wedge 9, the driving wedge 8 pushes the sliding seat 6 to slide and causes the support roller 5 to slide along the length direction of the support arm 2.

[0036] The specific implementation process is as follows:

[0037] Before the aluminum strip is rolled up, the driver 7 pulls the two driving wedges 8 to be close to each other, and the two support arms 2 are in a state of moving away from each other. When the aluminum strip needs to be rolled up on the reel 4, the two support arms 2 are first driven by the rotary hydraulic cylinder 3 to rotate to a state of being close to each other (i.e. Figure 1 state), and then use the driver 7 to push the two driving wedges 8 away from each other, and the driving wedges 8 and the fixed wedges 9 slide relative to each other, so that the driving wedges 8 push the sliding seat 6 to slide, and when the sliding seat 6 slides, it pushes the supporting roller 5 to slide along the length direction of the supporting arm 2, and finally the two supporting rollers 5 are close to each other and contact the reel 4. At this time, the two supporting rollers 5 play an auxiliary supporting role for the free end of the reel 4, so that it is not easy to be damaged in the subsequent process of reeling the aluminum plate and strip, and the accuracy of reeling is effectively improved.

[0038] When the winding roller completes one winding, the two drivers 7 first pull the driving wedges 8 at both ends closer to each other. At this time, under the elastic force of the reset spring 10, the sliding seat 6 and the support roller 5 are reset, and then the rotating hydraulic cylinder 3 is used to push the support arm 2 to rotate, so that the two support arms 2 rotate to a state of being away from each other. At this time, the aluminum plate strip rolled on the reel 4 can be removed from the free end of the reel 4 for the next winding work.

[0039] A coiler includes the above-mentioned movable supporting device, so that the coiler has a stable structure, can accurately complete the winding work, is not easy to be damaged, and has a long service life.

[0040] Example 2

[0041] The difference between Example 2 and Example 1 is that: Figure 3As shown, in actual application, since the size of the support arm 2 is generally large and its material is mostly metal, the weight is relatively heavy. In order to prevent accidents from causing the rotation of the support arm 2 to be uncontrolled, a limiter is provided on the base 1. When the free ends of the two support arms 2 rotate to a state away from each other, the support arm 2 and the limiter abut against each other to control the maximum rotation range of the support arm 2. For example, in this embodiment, the limiter is used to control the rotation of the support arm 2 to not exceed 90 degrees, that is, the vertical direction.

[0042] In this embodiment, the limiting member is a limiting seat 11 integrally formed on the base 1, and in order to reduce the impact noise generated when the support arm 2 contacts the limiting seat 11 and to provide effective buffering protection for the limiting seat 11, an elastic layer 12 is fixedly connected to the side where the limiting seat 11 contacts the support arm 2, and the elastic layer 12 can be elastic plastic, rubber, etc.

[0043] The above is only an embodiment of the utility model, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
