[0031] Example 1

[0032] Reference Figure 1 and Figure 2 , which is the first embodiment of the present invention, and provides a multiple-length brake device for a bar material cooling bed after steel polishing. The multiple-length brake device for a bar material cooling bed after steel polishing comprises a main control module 100, an execution module 200, a communication module 300 and an input module 400, wherein:

[0033] The main control module 100 coordinates and controls each module through the input module 400;

[0034] The execution module 200 is controlled by the main control module 100 and includes a multiple-length tail pressing device 201. The multiple-length tail pressing device 201 includes a pneumatic connecting rod structure 203 associated with the main control module 100;

[0035] The communication module 300 is connected to the main control module 100, and the execution module 200 communicates with the main control module 100 in real time through the communication module 300;

[0036] The execution module 200 forms a motion state synchronized with rolling through the main control module 100 .

[0037] Based on the above, the main control module 100 collects and processes various types of information as a terminal, and inputs and modifies information through the input module 200. The communication module 300 is associated with the main control module 100 to perform real-time communication between the execution module 200 and the main control module 100. The multiple-length tail pressing device 201 is synchronized with the production rhythm through the main control module 100, so that the device can be lifted and lowered accurately and smoothly; the program is used to adjust the pressure time of the device, so that the multiple-length steel throwing displacement can operate stably, and it can prevent the flying steel caused by the multiple-length sliding out of the cooling bed due to the rolling speed increase, thereby further improving the production rolling speed.

[0038] Example 2

[0039] Reference Figures 1 to 7 , which is the second embodiment of the present invention, and is different from the first embodiment in that: the multiple-length tail pressing device 201 includes a support seat 202, and a pneumatic connecting rod mechanism 203 is provided on the support seat 202. The pneumatic connecting rod mechanism 203 is placed above the support seat 202, and the middle end is movably connected to the support seat 202.

[0040] The multiple-length tail pressing device 201 is arranged at the front end of the upper steel device, including a support seat 202. The support seat 202 is vertically arranged at the front end of the upper steel device. Support frames are provided on both sides of the lower end of the support seat 202, so that the lower end of the support seat 202 is triangular, thereby making the device more stable, firm and pressure-resistant. A pneumatic connecting rod structure 203 is installed on the support seat 202. With the support seat 202 as the midpoint, the lengths of the two ends of the pneumatic connecting rod structure 203 are consistent, achieving a certain stability.

[0041] Furthermore, a cylinder assembly 204 is provided at one end of the pneumatic connecting rod mechanism 203, and a counterweight assembly 205 is provided at the other end. The end with the counterweight assembly 205 is close to the steel upper device, and the end with the cylinder assembly 204 is far away from the steel upper device.

[0042] The pneumatic connecting rod mechanism 203 includes a cross bar 203d perpendicular to the support seat 202, and one end of the counterweight assembly 205 includes a first connecting rod 203a and a second connecting rod 203b. The first connecting rod 203a and the second connecting rod 203b are arranged at the front and rear ends of the cross bar 203d, and the first connecting rod 203a and the second connecting rod 203b are connected by a connecting rod 203c. The connecting rod 203c is vertically arranged on the end surface of the cross bar 203d with the end surface of the cross bar 203d as the midpoint, and the first connecting rod 203a and the second connecting rod 203b are vertically symmetrically arranged relative to the connecting rod 203c. The first connecting rod 203a and the second connecting rod 203b are respectively composed of two rods, and a space is left between the two rods.

[0043] Furthermore, the counterweight assembly 205 includes a guide block 205a connected to the first connecting rod 203a and the second connecting rod 203b respectively. The guide block 205a is placed between the two rods, so that the connection of the guide block 205a is more stable, thereby extending the service life of the device. The lower part of the guide block 205a is welded to the pressure block 205b. The pressure block 205b is in the shape of a rectangular parallelepiped and is tilted. A counterweight plate 205c is welded between the two pressure blocks 205b. The bottom surface of the counterweight plate 205c is placed between the bottom surface and the top surface of the two pressure blocks 205b, and the top surface of the counterweight plate 205c is higher than the top surface of the pressure block 205b. Therefore, the counterweight plate 205c only plays a role in adjusting the pressure and cannot directly contact the friction plate, thereby increasing the friction between the scale and the friction plate, thereby realizing the braking displacement of the scale on the friction plate, and no scratches or bending of the steel will occur, meeting the production needs of speeding up the process and increasing production.

[0044] The pressure block 205b forms an angle of 12° with the horizontal plane and is adapted to the inclined friction plate. The guide block 205a is connected to the first connecting rod 203a and the second connecting rod 203b by a guide groove long hole pin, which makes installation convenient and can release shear force; it has strong seismic resistance and can effectively avoid the influence of the action of the cylinder assembly 204 on the pressure of the pressure block 205b, thereby improving the accuracy of the pressure of the pressure block 205b.

[0045] Furthermore, the multiple-length tail pressing device 201 controls the pressing block 205b through the cylinder assembly 204, and utilizes the self-weight of the counterweight block 205c to contact and press the multiple length, thereby increasing the friction between the finished multiple length and the friction plate, thereby realizing the braking displacement of the multiple length on the friction plate, meeting the production needs of process speed-up and production increase. The cylinder assembly 204 is a single-acting cylinder with a piston rod 204a at only one end, and one end of the piston rod 204a is connected to the pneumatic connecting rod mechanism 203. Air is supplied from one side of the piston to generate air pressure, and the air pressure pushes the piston rod 204a to generate thrust and extend, and returns by a spring or self-weight, and then the pneumatic connecting rod mechanism 203 realizes a swinging motion through a reversing valve with the support seat 202 as the end point, thereby achieving the contact and separation states of the pressing block 205b and the friction plate, and the movement is both sensitive and precise.

[0046] Specifically, the main control module 100 adopts a PLC control system, the input module 400 includes a keyboard 401 , a mouse 402 and operation buttons 403 for setting and modifying system parameters, and the communication module 300 is a TCP unit 301 .

[0047] The main control module 100 adopts the PLCS7-400 control system. Specifically, the main control module 100 adopts an automated control system and is controlled by a Siemens PLCS7-400 control system. On the basis of the original main rolling line program, it integrates the control programs of other PLC master stations on site, such as the 3# flying shear action program, the control programs of each oil station, etc., and designs and adds a program for simulating normal rolling current fluctuations, a program for simulating common fault settings on site, a rolling simulation program, etc. The PLCS7-400 control system is small in size, fast in speed, and standardized. It has network communication capabilities, stronger functions, and high reliability. It also has powerful control functions and powerful computing capabilities, and works very fast. It can carry a large number of input and output modules, and the types of input and output modules are also very comprehensive. The multiple-length tail pressing device 201 is synchronized with the production rhythm through PLC association, and the cylinder assembly 204 is controlled to make the pressing block 205b rise and fall accurately and smoothly. Figure 6 , Figure 7 As shown, the program is used to adjust the pressing time of the pressing block 205b, so that the double-length steel throwing displacement meets the production requirements, the operation is stable, and the production rolling speed is increased from the original 13.5 m / s to 15 m / s, thereby improving the production efficiency.

[0048] Further, the input module 400 uses a keyboard 401 with a USB interface, a mouse 402 with a USB interface, and an operation button 403 for setting and modifying simulation parameters and configurations;

[0049] TCP unit 301 is a communication protocol for wide area networks. Its purpose is to provide a communication method between two communication endpoints when communicating across multiple networks. It has a stream-based method, connection-oriented method, and reliable communication method. It minimizes the bandwidth overhead caused by retransmission when the network conditions are poor. The communication connection maintenance is oriented to the two communication endpoints, without considering the characteristics of the intermediate network segments and nodes.

[0050] Specifically, the main control module 100 is also connected to a display module 500 , a feedback module 600 , a storage module 700 and a power module 800 .

[0051] The display module 400 is used to display parameters, signals and other information, and adopts a display device 503 with an HDMI interface 501. The model of the display device 503 is AOC U27U2, and it is connected to the DSP unit 502 through the HDMI interface; the feedback module 600 adopts a PC terminal 601 and a mobile terminal 602. The PC terminal 601 is connected to the server 900 through the Ethernet port 603, and the mobile terminal 602 is connected to the server 900 through the web / wap unit 604. It is used for feedback on the results and process of the device's work, so that the operator can grasp the working progress of the device in real time, and can view information through the PC terminal 601 and the mobile terminal 602. The PC terminal 601 is connected to the server 900 through the Ethernet port 603, and the mobile terminal 602 is connected to the server 900 through the web / wap unit 604.

[0052] The storage module 800 uses a high-speed SRAM chip, model MT45W8MW16BGX-701IT, which is used to store temporary data storage and buffer, working variables, intermediate operation results, and flags during program execution.

[0053] The power module 800 includes a power supply 801 and a fuse 802 connecting the power supply 801 and the main control module 100. The fuse 802 prevents excessive current from causing harm to the device and can disconnect the circuit in an emergency.
