Description

Technical Field

[0001] The present application relates to the technical field of steel coil production equipment, and in particular to a novel hydraulic support device for the end of a coil. Background Art

[0002] At present, the slitting machine is a machine used to cut strips into strips of different specifications. The drive of the slitting machine blade adopts an oil cylinder. The oil cylinder uses a hydraulic pump as a power source. The hydraulic oil enters the piston through the hydraulic pipeline by the force of the pump and the solenoid valve. Then there are seals in the piston that cooperate with each other. The seals in different positions are different, but they all play a sealing role. However, during the long-term use of the oil cylinder, the seals will be damaged after long-term work. Once the seals are damaged, the bracket connected to the cutter will slide down, which is extremely dangerous for the staff who are performing maintenance or taking materials. Therefore, it is necessary to design a support device to solve the above technical problems. Utility Model Content

[0021] At present, if the oil cylinder of the slitting machine fails, the bracket connected to the cutter will slide down, which is extremely dangerous for the staff who are performing maintenance or taking materials.

[0022] In response to the above-mentioned problems, the solution provided in the present application can perform supporting and protective work under the supporting effect of the support arm in cooperation with the buffer spring assembly. At least two groups of connecting arms can provide multiple supports during the buffering process. Any one group of connecting arms is connected to the buffer spring assembly, which can transition the buffering force to the supporting force during the supporting process, thereby preventing the support table from bouncing and causing a large impact effect during the contact with the buffer table, thereby effectively protecting the safety of the device and the staff.

[0023] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0024] See also Figure 1-2, the present application provides a novel reel end hydraulic support device, comprising a buffer platform 1, a first mounting bracket 2, a second mounting bracket 3, a connecting frame 4, a connecting arm, a buffer spring assembly 12, and a support platform 18;

[0025] In this embodiment, the connecting frame 4 is hingedly connected to the second mounting bracket 3 through at least two groups of connecting arms. A buffer table 1 is installed on the top of the second mounting bracket 3. A first mounting bracket 2 is installed on the top of the buffer table 1. A buffer spring assembly 12 is hinged on any group of connecting arms. The buffer spring assembly 12 is adjustable. The end of the buffer spring assembly 12 away from the connecting arm is hinged to the first mounting bracket 2. The support platform 18 is installed on the cutter 11 and is used to contact the buffer table 1 to support the cutter 11. Specifically, in this embodiment, two groups of connecting arms are provided, including a first connecting arm 5 and a second connecting arm 6. The first connecting arm 5 is used to connect the first mounting bracket 2, the connecting frame 4, and the buffer spring assembly 12. Figure 1 As shown, the first connecting arm 5 is an L-shaped structure, the long side is used to connect the first mounting bracket 2 and the connecting frame 4, and the short side is connected to the buffer spring assembly 12. The second connecting arm 6 is a long strip-like structure parallel to the long side of the first connecting arm 5 to form a hinged support structure.

[0026] Specifically, the buffer spring assembly 12 includes a buffer spring 13, a nut 14, a hinge 15, and a bolt 16. The buffer spring 13 is sleeved on the bolt 16, and the nut 14 is installed on the bolt 16 to limit the buffer spring 13. The hinges 15 are arranged on both sides of the end of the bolt 16 for connecting the first mounting bracket 2 and the connecting arm. The distance between the nut 14 and the bolt 16 head can be adjusted by turning the nut 14, but the buffer spring 13 always generates a restoring force, so that the restoring force can be adjusted.

[0027] In other embodiments, a proximity switch 10 for sensing the support table 18 is installed on the first mounting bracket 2, and the connecting frame 4 is also connected to a cylinder 9, which is used to drive the connecting frame 4 to drive the buffer table 1 to dock with the support table 18 after the proximity switch 10 senses the support table 18. In the specific implementation process, the proximity switch 10 and the cylinder 9 can both be connected to the PLC of the slitting machine. That is, during the normal operation of the oil cylinder 17, the air cylinder 9 recovers, and the buffer table 1 and the support table 18 do not correspond in the vertical position (the buffer table 1 is not working). In the present embodiment, the hydraulic pump and the solenoid valve of the oil cylinder 17 are connected to the PLC of the slitting machine. When the hydraulic pump and the solenoid valve fail, or the internal seals are damaged, and the PLC does not send out an electrical signal to drive the hydraulic pump and the solenoid valve to work, the bracket connected to the cutter 11 slides down. After the proximity switch 10 is triggered, the PLC controls the air cylinder 9 to operate, and drives the connecting frame 4 to drive the buffer table 1 to dock with the support table 18. The buffer table 1 and the support table 18 correspond in the vertical position. However, when the cutter 11 is working normally, the bracket connected to the cutter 11 moves up and down normally, and the hydraulic pump and the solenoid valve work normally according to the PLC instructions, then the PLC control of the air cylinder 9 is not triggered. Figure 1 As shown, the support platform 18 moves downward and contacts the buffer platform 1. During the downward movement, the buffer spring 13 is squeezed to generate a restoring force. Under the supporting effect of the support arm, the buffer spring assembly 12 performs supporting and protecting work to protect the cutter 11 and prevent the cutter 11 from being damaged or injuring the staff due to the downward movement of gravity.

[0028] Specifically, in this embodiment, the connecting frame 4 is also connected to the slide rail 7 by setting a slider 8, one end of the slide rail 7 is provided with a vertical plate for mounting the cylinder 9, and the other end is provided with a buffer pad along the bottom of the second mounting bracket 3. The buffer pad has a secondary protection effect on the second mounting, and the cooperation between the slider 8 and the slide rail 7 also facilitates the driving of the cylinder 9 without being affected by gravity in the vertical direction, and is more linear.

[0029] The embodiments of the present application have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles of the embodiments, practical applications, or improvements to the technology in the market, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
