Description
Technical Field
[0001] The present application relates to the technical field of wire rod coiling production, and particularly to a pressure plate buffer device for a large-diameter wire rod uncoiler. Background Art
[0002] The equipment involved in the production process of wire rod coils includes a coiler, a wire rod uncoiler, a coil receiving machine, and a walking beam conveyor. The complete production process is repeated as follows: There are two coilers on the wire rod production line. When the wire rod of the No. 1 coiler ends, the production line will convey the wire rod to the No. 2 coiler through the steel splitter for coiling. Rotate the wire rod uncoiler above the No. 1 coiler; raise the tray of the No. 1 coiler below the pressure plate of the wire rod uncoiler. The wire rod on the tray will pass through the guide post of the wire rod uncoiler, and the pressure plate on the guide post will press on the top of the wire rod and rise together with the wire rod. Extend the telescopic claw of the wire rod uncoiler, hook the bottom of the wire rod, lower the tray of the No. 1 coiler, so that the wire rod is supported on the telescopic claw of the wire rod uncoiler. While rotating the wire rod uncoiler above the coil receiving machine, raise the coil receiving machine. When the wire rod uncoiler rotates above the coil receiving machine, the coil receiving machine also rises to the designated position synchronously to support the wire rod. Retract the telescopic claw of the wire rod uncoiler, lower the coil receiving machine to the coil receiving position of the walking beam conveyor, and make the wire rod uncoiler in a waiting state. (If the wire rod of the No. 2 coiler is completed, rotate the wire rod uncoiler above the No. 2 coiler and repeat the above steps.) Make the walking beam conveyor transport the coil away, raise the coil receiving machine to the waiting position, wait for the wire rod uncoiler to receive the coil and then rotate to the uncoiling position again to complete an uncoiling cycle.
[0003] The existing pressure plate buffer device of the wire rod uncoiler includes: a counterweight, a conduit, a steering wheel assembly, a wire rope kit, a pressure plate assembly and corresponding fasteners. The counterweight is installed in the conduit inside the guide post of the wire rod uncoiler, passes through the core shaft end of the wire rope kit, and is connected to the low end of the core shaft through a bolt flange. A spring for buffering is installed between the counterweight and the flange. By adjusting the weight of the counterweight, the falling speed of the pressure plate is controlled. The disadvantages are that this pressure plate buffer device not only has a complex structure, but also the internal space of the guide post of the wire rod uncoiler is narrow, resulting in very difficult and cumbersome installation and debugging, and it cannot adapt to wire rod rolling pieces with too large differences in wire rod height and specifications; in addition, when the pressure plate assembly reaches the limit position, hard contact usually occurs, and this direct contact method is extremely likely to cause component damage, affecting the normal operation and service life of the equipment; more critically, from the perspective of the overall equipment design, there is a lack of corresponding automatic detection structure to effectively monitor and warn such limit position states, which undoubtedly increases the risk of equipment failure and also highlights the deficiencies in automatic control and intelligent monitoring. Summary of the Invention
[0004] The present device provides a pressure plate buffer device for a large-diameter wire rod uncoiler, and the specific implementation is as follows:
[0005] A pressure plate buffer device for a large-diameter wire rod uncoiler, comprising:
[0006] A pressure plate slidably arranged on a guide post for pressing a wire rod coil, the pressure plate is provided with a guiding component slidably connected to a first vertical groove on the guide post, and the roller of the guiding component abuts against a telescopic claw;
[0007] A limiting component integrated on the pressure plate, which includes a limiting post with one end slidably connected to a second vertical groove on the guide post, the upper and lower ends of the second vertical groove are both closed, and the limiting post is internally provided with a cavity structure for installing a buffer and a proximity switch;
[0008] The buffer includes telescopic rods corresponding to the two ends of the second vertical groove respectively above and below, damping reset sleeves for resetting are respectively arranged above and below the telescopic rods, and a spring is arranged between the two damping reset sleeves. A notch is laterally opened at the end of the damping reset sleeve, the notch is vertically corresponding to the proximity switch, and the detection end of the proximity switch is laterally arranged, and the in-place detection at the upper and lower limit positions of the buffer is realized through a single proximity switch.
[0009] Based on the above technical solutions, by integrating the buffer and the proximity switch inside the limiting post, the telescopic rod can freely displace in the up and down directions; during this process, the spring and the damping reset sleeve, through their strain characteristics, not only provide an effective buffering effect but also ensure the subsequent reset effect; a single proximity switch is used to detect the position change of the two damping reset sleeves, so as to realize the precise detection of whether the pressure plate reaches the upper limit position or the lower limit position.
[0010] Preferably, the guiding component includes a V-shaped mounting frame and a plurality of first hinge seats circumferentially arranged on the pressure plate. Rollers are respectively arranged at both ends on the same side of the V-shaped mounting frame. The other side of the V-shaped mounting frame is hinged to the first hinge seat, and a first buffer pressure head is additionally installed at the hinge position.
[0011] Preferably, a second buffer pressure head is arranged downward at the other end of the limiting post, and the second buffer pressure head abuts against the top of the corresponding pressure plate.
[0012] Preferably, the connection ends of the second buffer pressure head and the first buffer pressure head are both threaded structures, and their abutting heights relative to the pressure plate are adjustable.
[0013] Based on the above technical solutions, the limiting post integrates the function of the counterweight of the original pressure plate buffer device of the wire rod uncoiler, and the large-sized wire rod can be compacted by adding weights on the limiting post.
[0014] Preferably, it further includes a controller. Angle sensors are installed at both the rotation part of the roller and the hinge joint of the V-shaped mounting bracket. The signal input end of the controller is electrically connected to each angle sensor and proximity switch, and its signal output end is connected to an external coil unloading drive structure.
[0015] Based on the above technical solutions, the falling speed of the pressure plate is detected in real time by the angle sensor or speed sensor at the rotation part of the roller. After adjusting the position of the buffer pressure head, the installation angle of the V-shaped mounting bracket can be detected by the angle sensor at the hinge joint of the V-shaped mounting bracket. The controller can be externally connected to conventional driving mechanisms for transporting steel coil plates, such as an alarm and a driving motor for the rotation of the jib.
[0016] Preferably, the outer contour of the damping reset sleeve is a tapered structure with a variable diameter and shrinking shape, and it is sleeved at the conducting position of the limiting post.
[0017] Preferably, the damping reset sleeve includes a cylindrical main body, and a plurality of elastic strain claws are arranged along its circumference. The outer contour of the elastic strain claws is obliquely arranged, and the outer side thereof abuts against the conducting position of the limiting post.
[0018] Preferably, an outer ring body and an inner ring body are respectively arranged at the upper and lower ends of the cylindrical main body, and a notch for the proximity switch to avoid obstacles is opened on the inner ring body.
[0019] Based on the above technical solutions, by setting the notch, it can be realized that both the upper and lower damping reset sleeves can pass through the proximity switch during lifting and lowering, and the proximity switch can be triggered by laterally recognizing the notch side of the notch during the passing process.
[0020] In summary, the present application includes the following beneficial technical effects:
[0021] 1. Through the improved pressure plate buffer device of the bar coil unloader of the present utility model, the structure is optimized without affecting the use and without changing its working principle. The counterweight block, conduit, steering wheel assembly, and wire rope kit are removed, and only the pressure plate assembly and corresponding fasteners are retained, thereby obtaining a pressure plate for coil unloading that is safe, efficient, and convenient to debug.
[0022] 2. In the improved pressure plate of the present utility model, not only a guiding component with a sliding buffer function is installed, but also a limiting component with a counterweight function and an end buffer function is installed. The rolling friction resistance between the roller and the vertical groove can be controlled by adjusting the tightness, thereby controlling the falling speed of the pressure plate assembly. The upper and lower limit positions of the improved pressure plate assembly can also be controlled by the buffer structure on the limiting component. By adjusting the tightness of the buffer device, the impact at the lower limit can be reduced when the falling speed of the pressure plate is too fast.
[0023] 3. The structure of the utility model is simple. By integrating both the buffer and the proximity switch into the limit post, the telescopic rod can move up and down. The strain of the spring and the damping reset sleeve can provide buffering and subsequent reset effects. It can also use a single proximity switch to detect the position changes of the two damping reset sleeves, thereby achieving the in-place detection of the pressure plate at the upper limit position or the upper limit position.

[0041] The following describes the specific implementation mode of the present invention in conjunction with the accompanying drawings and embodiments:
[0042] It should be noted that the structures, ratios, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those familiar with this technology to understand and read, and are not used to limit the limited conditions under which the present invention can be implemented.

[0043] At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" cited in this specification are only for the convenience of clear narration, and are not used to limit the scope within which the present invention can be implemented. The change or adjustment of their relative relationship, without substantial change in the technical content, should also be regarded as the scope within which the present invention can be implemented.
[0044] The following combines the attached Figure 1-9 The present application will be further described in detail.
[0045] The embodiment of the present application discloses a pressure plate buffer device for a large-diameter wire rod uncoiler.
[0046] Comparative example 1
[0047] Combine Figure 1, this comparative example discloses a conventional pressure plate buffer device, including a swing arm 11 for transporting the coiled bar steel coil after coiling. At the other end of the swing arm 11, there is a guide post 1. A pressure plate 12 is vertically slidably arranged on the guide post 1. And the guide post 1 integrates a conduit divided into upper and lower sections. The lower section is welded inside the guide post 1 of the bar uncoiler, and the upper section is fixedly connected by bolts through a flange plate to the top surface of the swing arm 11 of the bar uncoiler. There is a partially overlapping area between the upper and lower sections. The conduit can be used to control the spatial position of the counterweight structure 14, ensuring that the counterweight structure 14 can only move up and down and will not swing arbitrarily inside the guide post of the bar uncoiler due to the rotation of the swing arm of the bar uncoiler. It also includes a wire rope kit for connecting the pressure plate 12 and the counterweight structure 14. By adjusting the length of the wire rope, the lowest position of the pressure plate 12 falling is restricted. The bar steel coil just taken out from the coiler is relatively loose. In order to ensure that the bar steel coil will not jolt and scatter during its subsequent transportation due to transfer between various equipment, the pressure plate itself should have an appropriate weight. However, it is necessary to ensure that when the pressure plate 12 rises as the bar passes through the guide post 1 of the bar uncoiler, it will not deform the top of the bar steel coil due to excessive self-weight, and when the pressure plate 12 descends as the coiling machine takes away the bar, it will not cause the bar steel coil to jolt and scatter during transfer between various equipment because the falling speed is too slow to compact the bar steel coil.
[0048] Example 1
[0049] Refer to Figures 2 to 5 , this example discloses a pressure plate buffer device for a large-diameter bar uncoiler, including a limit component 3 integrated on the pressure plate 12 and a pressure plate 12 slidably arranged on the guide post 1 for pressing the bar steel coil. The pressure plate 12 is provided with a guide component 2 slidably connected to the first vertical groove 101 on the guide post 1. The roller 202 of the guide component 2 abuts against the telescopic claw 13, and the release of the bar steel coil on the guide post 1 is realized by changing its abutting position. In this structure, the limit component 3 includes a limit post 302 with one end slidably connected to the second vertical groove 102 on the guide post 1, and both the upper and lower ends of the second vertical groove 102 are closed.
[0050] The guiding assembly 2 includes a V-shaped mounting bracket 201 and a plurality of first hinge seats 203 arranged circumferentially on the pressure plate 12. Roller wheels 202 are respectively provided at both ends on the same side of the V-shaped mounting bracket 201. The other side of the V-shaped mounting bracket 201 is hinged to the first hinge seat 203, and a first buffer head 204 is additionally installed at the hinge position. The limiting column 302 is hinged to the second hinge seat 301, and the other end of the limiting column 302 is provided with a second buffer head 303 downward. The second buffer head 303 abuts against the top of the corresponding pressure plate 12. In this structure, the connecting ends of the second buffer head 303 and the first buffer head 204 are both threaded structures, and their abutting heights relative to the pressure plate 12 are adjustable. The first hinge seat 203 and the second hinge seat 301 are respectively detachably installed on the first mounting seat 1201 and the second mounting seat 1202 of the pressure plate 12 by bolts, and a lifting hook 1203 is additionally installed on the pressure plate 12.
[0051] Embodiment 2
[0052] Referring to Figures 3 to 9 , and based on Embodiment 1, this embodiment also provides a pressure plate buffer device for a large-diameter wire rod uncoiler, which further includes a controller. The limiting column 302 is internally provided with a cavity structure for installing a buffer member and a proximity switch 7. The buffer member includes a telescopic rod 304 whose upper and lower parts respectively correspond to both ends of the second vertical groove 102. Damping return sleeves 305 for resetting are respectively provided above and below the telescopic rod 304, and a spring 306 is provided between the two damping return sleeves 305. A notch 3054 is laterally opened at the end of the damping return sleeve 305, and the notch 3054 is vertically corresponding to the proximity switch 7, and the detection end of the proximity switch 7 is laterally arranged. The in-place detection at the upper and lower limit positions of the buffer member is realized through a single proximity switch 7, and the proximity switch 7 is suspended in the limiting column 302 through a mounting seat 6.
[0053] A first angle sensor 4 and a second angle sensor 5 are respectively additionally installed at the rotating part of the roller wheel 202 and the hinged part of the V-shaped mounting bracket 201. The signal input end of the controller is electrically connected to each angle sensor and the proximity switch 7, and its signal output end is connected to an external uncoiling driving structure.
[0054] The outer contour of the damping return sleeve 305 is a tapered structure with a variable diameter and shrinking. It is sleeved at the conducting position of the limiting column 302. The damping return sleeve 305 includes a cylindrical main body, and a plurality of elastic strain claws 3052 are circumferentially opened on it. The outer contour of the elastic strain claws 3052 is obliquely arranged, and its outer side abuts against the conducting position of the limiting column 302. In this structure, an outer ring body 3051 and an inner ring body 3053 are respectively provided at the upper and lower ends of the cylindrical main body, and a notch 3054 for the proximity switch 7 to avoid obstacles is opened on the inner ring body 3053.
[0055] The specific implementation process is as follows: When the pressure plate 12 reaches the lower end of the second vertical groove 102, the end of the telescopic rod 304 impacts the lower end of the second vertical groove 102. At this time, the damping reset sleeve 305 at the bottom moves upward, and the damping reset sleeve 305 at the top remains stationary; the elastic strain claw 3052 deforms, and the spring 306 is compressed. After the damping reset sleeve 305 moves to the limit position, the notch 3054 passes through the proximity switch 7 to trigger it, and a signal indicating reaching the lower limit position is transmitted to the sensor; conversely, when the pressure plate 12 reaches the upper end of the second vertical groove 102, the principle is the same; when the pressure plate 12 leaves the end face of the second vertical groove 102, both the elastic strain claw 3052 and the spring 306 are reset, and the limit component 3 is reset.
[0056] Many other changes and modifications can be made without departing from the spirit and scope of the present invention. It should be understood that the present invention is not limited to a specific embodiment, and the scope of the present invention is defined by the appended claims.
