Description

Technical Field

[0001] This application relates to the field of metal rolling technology, and in particular to a buffer protection device for bar and wire rods. Background Technology

[0002] In the current rolling process of metal bars or wires, after finishing rolling, the steel is directly fed into a coiler or wire rod mill for coiling and other operations. However, the temperature of the bars and wires is relatively high after finishing rolling, and directly proceeding to the next step may cause deformation of the bars and wires, resulting in defective products. In addition, since there is no feedback device between the coiler, wire rod mill, and other post-rolling processing equipment and the rolling mill, when the coiler malfunctions, the machine in the previous stage cannot receive effective feedback, which often leads to problems such as large amounts of steel accumulation, and may even damage the finishing rolling machine for bars and wires. Utility Model Content

[0003] The main purpose of this application is to provide a bar and wire rod buffer protection device, which aims to solve the technical problem that existing steel rolling post-processing equipment lacks a feedback mechanism, which easily leads to steel piling and even damage to the finishing rolling machine.

[0004] To achieve the above objectives, this application provides a rod and wire buffer protection device, including a housing, a lower guide groove, an upper guide groove, and a detection mechanism. The housing has openings on both sides for rods and wires to enter and exit. The lower guide groove is disposed inside the housing and located between the two openings. The upper guide groove is hinged inside the housing and located above the lower guide groove. The upper guide groove and the lower guide groove form a cavity for rods and wires to pass through, and the cavity connects to the two openings. The detection mechanism is disposed inside the housing and is used to detect whether the upper guide groove rotates abnormally.

[0005] Optionally, the detection mechanism includes a contact wire, a first counterweight, and a sensor. One end of the contact wire is located inside the housing and above the upper guide groove. When the upper guide groove rotates abnormally, it can touch the contact wire. The other end of the contact wire moves through the side wall of the housing. The first counterweight is connected to the end of the contact wire located on the outside of the housing. The sensor is set on the outer wall of the housing and is used to detect changes in the position of the first counterweight.

[0006] Optionally, at least two upper guide grooves are provided, and the contact lines inside the housing are arranged in a zigzag pattern so that there is a contact line above each upper guide groove.

[0007] Optionally, a guide cylinder is provided on the outer wall of the box, the first counterweight is slidably disposed in the guide cylinder, and a detection port facing the sensor is opened on the side wall of the guide cylinder.

[0008] Optionally, a hinge seat is provided on the side wall of the lower guide groove, and a connecting part that is hinged to the hinge seat is provided on the side wall of the upper guide groove.

[0009] Optionally, an extension rod is provided on the side wall of the upper guide groove away from the hinge seat, and several second counterweights are movably sleeved on the extension rod.

[0010] Optionally, the enclosure is equipped with a spray cooling mechanism for spraying cooling water onto the rods and wires.

[0011] Optionally, the spray cooling mechanism includes a spray pipe, a water inlet pipe, a first flange, and a shut-off valve. The spray pipe is located inside the box and has multiple nozzles facing the bar wire. One end of the spray pipe extends out of the box. The water inlet pipe is connected to the end of the spray pipe that extends out of the box. The first flange is connected to the other end of the water inlet pipe. The shut-off valve is installed on the water inlet pipe.

[0012] Optionally, a drain pipe is provided at the bottom of the enclosure, and the other end of the drain pipe is connected to a second flange.

[0013] Optionally, an inlet guide and an outlet guide are respectively installed on the two outer side walls of the enclosure, directly opposite the opening.

[0014] The beneficial effects that this application can achieve are as follows: This application includes a housing, a lower guide chute, an upper guide chute, and a detection mechanism. The housing has openings on both sides for the entry and exit of bar and wire rods. The lower guide chute is located inside the housing between the two openings. The upper guide chute is hinged inside the housing and located above the lower guide chute. The upper and lower guide chutes form a cavity for the bar and wire rod to pass through, and the cavity connects to the two openings. The detection mechanism is located inside the housing and is used to detect whether the upper guide chute rotates abnormally. When the bar and wire rods pass through the housing and through the cavity between the upper and lower guide chutes, because the upper guide chute is movably connected above the lower guide chute, if the coiling machine or wire drawing machine malfunctions, the bar and wire rods will bend or deform and accumulate within the cavity. When the force exerted by the bar and wire rods on the upper guide chute exceeds the weight of the upper guide chute, the upper guide chute will rotate significantly or even be lifted. The detection mechanism can detect the rotation of the upper guide chute to determine if an abnormality has occurred, allowing for timely alarm or automatic shutdown of the previous process. This provides an abnormality feedback function, reducing the risk of steel accumulation and damage to the finishing mill. Attached Figure Description

[0023] Example Reference Figures 1-7 This embodiment provides a rod and wire buffer protection device, including a housing 110, a lower guide groove 120, an upper guide groove 130, and a detection mechanism 140. The housing 110 has openings on both sides for rods and wires to enter and exit. The lower guide groove 120 is disposed inside the housing 110 and located between the two openings. The upper guide groove 130 is hinged inside the housing 110 and located above the lower guide groove 120. The upper guide groove 130 and the lower guide groove 120 form a cavity for rods and wires to pass through, and the cavity is connected to the two openings. The detection mechanism 140 is disposed inside the housing 110 and is used to detect whether the upper guide groove 130 has rotated abnormally (i.e., the upper guide groove 130 has rotated significantly or been directly lifted).

[0024] In this embodiment, when the bar wire passes through the housing 110 and through the cavity between the upper guide groove 130 and the lower guide groove 120, since the upper guide groove 130 is movably connected above the lower guide groove 120, when the coiling machine or the spinning machine malfunctions, the bar wire will bend and deform in the cavity and accumulate. When the force exerted by the bar wire on the upper guide groove 130 is greater than the weight of the upper guide groove 130, the upper guide groove 130 will rotate significantly or even be lifted up. At this time, the rotation of the upper guide groove 130 can be detected by the detection mechanism 140 to determine whether an abnormality has occurred, so as to promptly alarm or automatically stop the previous process, thereby providing buffer protection and having an abnormality feedback function, reducing the risk of steel accumulation and damage to the finishing mill.

[0025] As an optional implementation, the detection mechanism 140 includes a contact line 141, a first counterweight 142, and a sensor 143. One end of the contact line 141 is located inside the housing 110 and above the upper guide groove 130. When the upper guide groove 130 rotates abnormally, it can touch the contact line 141. The other end of the contact line 141 moves through the side wall of the housing 110. The first counterweight 142 is connected to the end of the contact line 141 located outside the housing 110. The sensor 143 is disposed on the outer wall of the housing 110 and is used to detect changes in the position of the first counterweight 142.

[0026] In this embodiment, when the upper guide groove 130 rotates significantly or is lifted, it will touch the contact line 141 (which can be a fishing line) and lift it up. This causes the contact line 141 to pull up the first counterweight 142. The sensor 143 (which can be a proximity switch or distance sensor, etc.) can immediately detect the position change of the first counterweight 142, thereby instantly detecting the abnormality and providing timely feedback. The sensor 143 can be electrically connected to a controller (which can be a PLC controller of model S7-200). The controller is electrically connected to an alarm or related finishing mill equipment, so that it can immediately alarm or control the relevant finishing mill equipment to stop automatically after detecting the abnormality.

[0027] As an optional implementation, the upper guide groove 130 is provided with at least two, and the contact line 141 located in the housing 110 is arranged in a zigzag shape so that there is a contact line 141 above each upper guide groove 130.

[0028] In this embodiment, since the bending position of the bar wire may be different, multiple independently rotatable upper guide grooves 130 can be set to react in time to the bar wire at different bending positions, thereby improving the immediacy of detection. Here, hanging rings can be installed at corresponding positions on the inner wall of the housing 110, and the contact wire 141 can be arranged in a zigzag pattern by passing around the corresponding hanging ring. For example, when there are two upper guide grooves 130, the contact wire 141 is V-shaped; when there are three upper guide grooves 130, the contact wire 141 is N-shaped; when there are four upper guide grooves 130, the contact wire 141 is M-shaped, and so on. Thus, one contact wire 141 can cover all upper guide grooves 130, without the need to set a separate contact wire 141 for each upper guide groove 130.

[0029] As an optional implementation, a guide cylinder 144 is provided on the outer wall of the housing 110, and the first counterweight 142 is slidably disposed in the guide cylinder 144. The side wall of the guide cylinder 144 is provided with a detection port facing the sensor 143. When the first counterweight 142 is pulled up, it can be guided by the guide cylinder 144 to prevent excessive shaking when pulled up. When the first counterweight 142 is pulled up, the sensor 143 can detect the position change of the first counterweight 142 through the detection port.

[0030] As an optional implementation, the lower guide groove 120 is provided with a hinge seat 150 on its side wall, and the upper guide groove 130 is provided with a connecting part 131 that is hinged to the hinge seat 150 on its side wall, so that it can rotate flexibly, and the upper guide groove 130 and the lower guide groove 120 can be tightly closed.

[0031] As an optional implementation, an extension rod 160 is provided on the other side wall of the upper guide groove 130 away from the hinge seat 150. Several second counterweights 170 are movably sleeved on the extension rod 160. The second counterweights 170 can increase the tightness of the closure of the upper guide groove 130 to the lower guide groove 120 and prevent the upper guide groove 130 from being accidentally opened due to shaking.

[0032] As an optional implementation, the housing 110 is equipped with a spray cooling mechanism 180. The spray cooling mechanism 180 sprays cooling water onto the bar / wire. By continuously spraying cooling water onto the lower guide trough 120 and upper guide trough 130, the bar / wire being conveyed is cooled, ensuring easier winding while preventing surface deformation due to excessive temperature, thus reducing costs. It should be noted that the lower guide trough 120 and upper guide trough 130 can be made of materials that facilitate heat exchange to improve the cooling effect.

[0033] As an optional implementation, the spray cooling mechanism 180 includes a spray pipe 181, a water inlet pipe 183, a first flange 184, and a shut-off valve 185. The spray pipe 181 is located inside the housing 110, and multiple nozzles 182 facing the bar / wire are provided on the spray pipe 181. One end of the spray pipe 181 extends out of the housing 110. The water inlet pipe 183 is connected to the end of the spray pipe 181 that extends out of the housing 110. The first flange 184 is connected to the other end of the water inlet pipe 183. The shut-off valve 185 is provided on the water inlet pipe 183. The water inlet pipe 183 can be connected to an external water pipe through the first flange 184. When water is introduced, cooling water can be sprayed onto the lower guide groove 120 and the upper guide groove 130 through the multiple nozzles 182 to fully cool the bar / wire.

[0034] As an optional implementation, a drain pipe 190 is provided at the bottom of the box 110, and the other end of the drain pipe 190 is connected to a second flange 210. The water after spraying can be collected at the bottom of the box 110 and discharged from the drain pipe 190. The drain pipe 190 can be connected to a sewage pipeline through the second flange 210 for subsequent centralized treatment.

[0035] As an optional implementation, an inlet guide head 220 and an outlet guide head 230 are respectively provided on the two outer side walls of the housing 110 facing the opening, and the bar wire can be stably guided through the inlet guide head 220 and the outlet guide head 230. The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
