Description

Technical Field

[0001] The invention relates to the technical field of metal coil strip production, and in particular to a movable single-arm support seat and a working method thereof. Background Art

[0002] Winders or uncoilers are widely used in the winding or unwinding part of coil and strip processing production lines. For aluminum strips with small widths, cantilever winders or uncoilers are usually used. However, when the weight of the coil is heavy or the tension of the strip is large, the cantilever reel is subjected to a large bending moment during high-speed winding or unwinding, and is prone to swing or even bend and deform under heavy vibration loads. Therefore, auxiliary support is required for the cantilever end. The current situation is that some equipment manufacturers use a stand or roller frame to assist in supporting the cantilever end of the reel, which can alleviate the swing to a certain extent. However, these brackets have simple structures, cannot position the cantilever end of the reel in all directions, and have poor stability.

[0003] Therefore, it is necessary to develop a movable single-arm support seat and a working method thereof to overcome the above-mentioned defects. Summary of the invention

[0042] Specifically, if Figures 1 to 4 As shown, the translation drive mechanism includes a translation oil cylinder 8, a shaft seat is provided at the top of the driving arm 5, a shaft is provided at the middle of the cylinder barrel of the translation oil cylinder 8, the shaft is installed in the shaft seat and is crimped and assembled through the shaft cover 501. The piston rod end of the translation oil cylinder 8 is pin-connected with a push-out seat 603, and the bottom end of the push-out seat 603 is fixedly connected to the outer wall of the supporting main arm 6.

[0043] Obviously, the translation drive mechanism can also adopt a screw slider structure, the screw is arranged parallel to the guide shaft 4, the slider is fixedly connected to the support main arm 6, and the reduction motor drives the screw to rotate to adjust the front and rear position of the support main arm 6.

[0045] In a specific embodiment of the present invention, Figure 3 and Figure 5 As shown, the circumferential locking structure includes a guide key strip 401, which is fixedly laid on the outer wall of the guide shaft 4 parallel to the axis of the guide shaft 4 and fixedly connected by countersunk screws. A key groove adapted to the guide key strip 401 is provided on the inner wall of the hole in the main sleeve 601.

[0046] Specifically, if Figure 3 and Figure 5 As shown, the main sleeve 601 is provided with a compression sleeve 6011 and a third bushing 6012 nested from outside to inside in the middle hole. The third bushing 6012 is made of wear-resistant cast iron or tin bronze. A circumferential limit flat key is provided between the compression sleeve 6011 and the main body hole of the main sleeve 601. Baffles are provided at both ends of the main sleeve 601 to prevent the compression sleeve 6011 from falling out. A grease channel for replenishing lubricating grease toward the sliding pair is also provided on the outer wall of the main sleeve 601.

[0047] By laying the guide key strip 401, a corresponding key groove is opened on the inner wall of the hole in the main sleeve 601, and circumferential locking is performed to prevent the supporting main arm 6 from rotating relative to the guide shaft 4; by setting the clamping sleeve 6011 and the third bushing 6012, disassembly, maintenance and replacement are facilitated, while the service life of the equipment is increased.

[0048] In a specific embodiment of the present invention, Figure 3 and Figure 5 As shown, the movable single-arm support seat of the present invention further includes a limiting slide plate 12, which is vertically arranged on the base 1, and the sliding surface of the limiting slide plate 12 is parallel to the axis of the guide shaft 4, and the sliding surface of the limiting slide plate 12 is provided with a sliding bar 1201.

[0052] By setting the positioning pin 602 and the pin hole 302, when the main arm 6 is in working state, the pin can be positioned at the top and matched with the sliding surface limit at the bottom, so that the span between the two points of the main arm 6 is large, the support rigidity is increased, and the positioning accuracy of the sleeve block 10 is improved. At the same time, it can prevent the swing hydraulic cylinder from malfunctioning and causing damage to the cantilever drum.

[0053] In a specific embodiment of the present invention, Figure 1 and Figure 2 As shown, the sleeve block 10 is connected to the mounting groove surface of the supporting main arm 6 through two horizontal and vertical connecting flange plates, and the two mounting groove surfaces are provided with adjustment pads 11 that are easy to replace.

[0055] The movable single-arm support seat of the present invention can support the main arm 6 to perform translation and swinging movements through the arrangement of the guide shaft 4, the translation drive mechanism and the swing drive mechanism. When entering the working state, the middle hole of the sleeve block 10 sleeves the outer end shaft section of the cantilever reel to provide auxiliary support for it; when entering the retracted state, the main arm 6 is retracted outward and backward to allow space for loading and unloading operations of the discharge roll 14, which is convenient for operation. The movable single-arm support seat of the present invention is fully surrounded by the sleeve block and supported on the cantilever end of the reel, with 360-degree all-round positioning support. The outer end of the cantilever reel will not swing up and down or left and right, and the equipment has good operating stability. In addition, by adopting the swing drive mechanism and the translation drive mechanism driven by a hydraulic cylinder, it is easy to implement and can perform displacement control, with high support strength, which is convenient for stable support of the main arm 6. By laying the guide key bar 401, the corresponding key slot is provided on the inner wall of the hole in the main sleeve 601, and the circumferential locking can prevent the support main arm 6 from rotating relative to the guide shaft 4; by setting the clamping sleeve 6011 and the third bushing 6012, it is easy to disassemble, maintain and replace, and at the same time, the service life of the equipment is improved. By setting the limit slider 6041 and the sliding bar 1201, the sliding surface limiting method is adopted, which can prevent the hydraulic drive element from over- or under-driving the guide shaft 4 to rotate, and ensure the working state positioning accuracy of the socket block 10. By setting the positioning pin 602 and the pin shaft hole 302, when entering the working state, the pin shaft positioning can be carried out at the top of the support main arm 6 and matched with the sliding surface limiting at the bottom, the two-point span of the support main arm 6 is large, the support stiffness is increased, and the positioning accuracy of the socket block 10 is improved. At the same time, it can prevent the swing hydraulic cylinder from causing damage to the cantilever drum due to misoperation. By adjusting the setting of the pad 11, the installation position of the socket block 10 can be slightly adjusted in both horizontal and vertical directions to compensate for the positioning accuracy error when the equipment base is installed.

[0056] The present invention also discloses a working method of a movable single-arm support seat, which uses the movable single-arm support seat in any of the above embodiments to roll or unroll the metal coil 14, including the following steps:

[0057] S1. The swing drive mechanism drives the guide shaft 4 to rotate, and the supporting main arm 6 swings along with the guide shaft 4. When the middle hole of the sleeve block 10 is coaxial with the outer end shaft section of the cantilever reel, the drive is stopped.

[0058] S2, the translation drive mechanism drives the supporting main arm 6 to move along the guide shaft 4, the middle hole of the sleeve block 10 is inserted into the outer end shaft section of the cantilever reel, and the drive is stopped.

[0059] S3. After winding or unwinding is completed, the translation drive mechanism drives the supporting main arm 6 to retreat along the guide shaft 4, and the swing drive mechanism drives the guide shaft 4 to rotate back, and the supporting main arm 6 is reset to prepare for the next action.

[0060] Specifically, in step S2, the piston rod of the translation cylinder 8 pushes the push-up seat 603, and the supporting main arm 6 moves inward. First, the limit slider 6041 contacts the sliding bar 1201 and slides in a plane guide. When entering the working state, the positioning pin 602 is inserted into the pin shaft hole 302 for protective positioning.

[0061] The working method of the movable single-arm support seat of the present invention can not only meet the function of auxiliary support of the outer end of the cantilever drum, but also fully retreat to make room for loading and unloading by supporting the translation and swinging combination of the main arm 6. The double large-span positioning of the plane guide and the positioning pin can improve the positioning accuracy and support rigidity, and reduce the yaw vibration of the cantilever drum.
