Description

Technical Field

[0001] The utility model relates to the field of steel processing, in particular to a steel pushing device for pushing steel in rolling. Background Art

[0002] A pusher is a special equipment used on a steel rolling production line to push steel billets into a heating furnace for heating. Currently, most pushers consist of a base, a push plate, a hydraulic cylinder and other components. The hydraulic cylinder pushes the push plate to drive the steel billet to move and push the steel billet into the heating furnace.

[0003] A pusher head of a steel pusher with the prior art publication number CN213968931 U includes a pusher head, rollers, pins, brackets, guide wheels, guide rails, ingots, stacking platforms and rollers. Three grooves are provided between the ribs at the front end of the pusher head, and a bracket is welded on both sides of each groove. Rollers are installed between each pair of brackets through pins. The rollers can support the pusher head to slide on the upper surface of the stacking platform and the rollers. A guide rail is provided at the rear end of the pusher head, and the guide rail can slide back and forth relative to the guide wheel. A group of rollers is provided on the upper right side of the left end of the stacking platform. Each roller is arranged parallel to the ground. The top surface height of the roller is lower than the bottom surface height of the pusher head. The rollers can support the ingots to slide on their top surface. The pusher head of the pusher utilizes rolling friction instead of sliding friction, significantly reducing the various forces generated by sliding friction. When the ingot is in place on the stacking table, although there is downward displacement, the rotation of the rollers at this time smoothly eliminates the various forces generated by the relative displacement. The service life of the pusher's guide wheels and the pusher's travel guide rails is significantly improved. In the process of implementing this technical solution, the inventors discovered that the existing technology has at least the following problems:

[0004] In the prior art, the so-called stacking platform is usually a stacking platform for steel billets in front of a heating furnace. When a certain amount of steel billets accumulate on the stacking platform, the steel billets need to be pushed into the heating furnace. However, since the working environment of the steel pusher is relatively harsh, that is, the steel pusher is generally located near the heating furnace, and the temperature of the heating furnace is relatively high, the temperature of the heating furnace will radiate to the push plate, and the steel billets generally have a certain temperature, and the temperature of the steel billets can also be transmitted to the push plate, and the push plate will transmit the high temperature to the hydraulic cylinder.

[0028] Since the working environment of the steel pusher is relatively harsh, that is, the steel pusher is generally located near a heating furnace, and the temperature of the heating furnace is relatively high, the temperature of the heating furnace will radiate to the push plate, and the steel billet generally has a certain temperature, and the temperature of the steel billet can also be transferred to the push plate, and the push plate will transfer the high temperature to the hydraulic cylinder. Over time, the hydraulic cylinder is affected by the high temperature, which will cause the hydraulic cylinder components to be damaged by heat, making it impossible to continue to use, reducing the service life of the device. Therefore, after research, the inventor provides a steel pushing device for rolling mill, which can continuously cool the push plate during the production process, avoiding the problem of the push plate continuously heating up due to the influence of the heating furnace and steel temperature, and then the hydraulic cylinder being affected by the high temperature due to the heat conduction effect, resulting in heat damage to the hydraulic cylinder components and reducing the service life of the device.

[0029] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0030] Please refer to Figure 1 As shown, the embodiment of the present invention provides a steel pushing device for rolling steel, comprising a steel pushing machine assembly 100 and a cooling assembly 200. The steel pushing machine assembly 100 is used to push the steel into the heating furnace, and the cooling assembly 200 is used to cool the steel.

[0031] Please refer to Figure 2 As shown, the steel pusher assembly 100 includes a support frame 110, a hydraulic push rod assembly 120, and a push head 130. The hydraulic push rod assembly 120 is fixedly connected to the top of the support frame 110, and the push head 130 is fixedly connected to the output end of the hydraulic push rod assembly 120. A water outlet pipe 140 and a water return pipe 150 are respectively provided on both sides of the support frame 110. Activating the hydraulic push rod assembly 120 drives the push head 130 to move, thereby pushing the steel. A billet heater 160 is provided at the rear end of the support frame 110, and the end face of the support frame 110 corresponds to the heating chamber of the billet heater 160. The billet heater 160 is used to heat steel during production. The correspondence between the end face of the support frame 110 and the heating chamber of the billet heater 160 facilitates the push head 130 to push the steel smoothly and neatly into the heating chamber.

[0032] Please refer to Figure 3As shown, the cooling assembly 200 includes a water tank 210, a water pump 220, a water outlet hose 230, a spray element 240, and a water return hose 250. The water tank 210 is placed below the support frame 110, and has pipe openings at both ends corresponding to the water outlet pipe 140 and the water return pipe 150. The water pump 220 is installed in the water tank 210. One end of the water outlet hose 230 is connected to the water tank 210 through the water outlet pipe 140, and the other end of the water outlet hose 230 is fixedly connected to one end of the spray element 240. One end of the water return hose 250 is connected to the water tank 210 through the return pipe 150, and the other end of the water return hose 250 is fixedly connected to the other end of the spray element 240. The spray element 240 is fixedly connected to the top of the push head 130. The water outlet pipe 140 and the water return pipe 150 are both telescopic hoses with a certain reserved value. The coolant is added to the water tank 210. During production and processing, the water pump 220 is started to allow the coolant to enter the spray part 240 through the water outlet hose 230. The spray part 240 sprays part of the coolant onto the push head part 130, so that the push head part 130 always maintains a relatively low temperature. The coolant that is not completely squeezed out and sprayed returns to the water tank 210 for reuse through the return hose 250. In addition, the sprayed coolant can also be collected and returned to the water tank 210 for reuse until it can no longer be reused. The push head part 130 is cooled by the spray part 240, and the coolant can be reused by using the return hose 250 and the water flow characteristics. Therefore, the push head part 130 can be continuously cooled during the production process, so that the hydraulic cylinder is also within a normal temperature range, avoiding the problem in the prior art that the push plate continues to heat up due to the influence of the heating furnace and the steel temperature, and then the hydraulic cylinder is affected by the high temperature due to the heat conduction effect, resulting in heat damage to the hydraulic cylinder components and reduced service life of the device.

[0033] Please refer to Figure 4As shown, the support frame 110 includes a flat frame 111 and support vertical plates 112. The support vertical plates 112 are fixedly connected to both sides of the flat frame 111. A mounting cavity 113 is formed between the support vertical plates 112, and a water tank 210 is placed in the mounting cavity 113. The water tank 210 is movably placed in the mounting cavity 113. The water outlet hose 230 and the return hose 250 are removed separately, and the water tank 210 can be pulled out and cleaned separately. A mounting groove 114 is provided on the side of the flat frame 111 near the steel billet heating machine 160. Rollers 115 are rotatably connected to the mounting groove 114 and are evenly distributed within the mounting groove 114. When pushing the steel billet, the steel billet rolls on the rollers 115 and finally enters the steel billet heating machine 160, making it easier for the pusher head 130 to push the steel billet and reducing the various forces generated by relative displacement due to sliding friction. The hydraulic push rod assembly 120 includes a hydraulic frame 121, a hydraulic push rod 122, and a stabilizing sliding rod 123. The hydraulic frame 121 is fixedly connected to the top of the support frame 110. The hydraulic push rod 122 is symmetrically connected to both sides of the hydraulic frame 121. The push head 130 is fixedly connected to the output end of the hydraulic push rod 122. One end of the stabilizing sliding rod 123 is fixedly connected to both sides of the push head 130, and the other end of the stabilizing sliding rod 123 passes through the hydraulic frame 121 and extends out of the hydraulic frame 121. When the hydraulic push rod 122 is started, the push head 130 is driven to move, and at the same time, the stabilizing sliding rod 123 is driven to slide on the hydraulic frame 121, thereby improving the movement stability of the push head 130. The push head 130 is an inverted L-shaped structure, and the push head 130 is provided with a gap 131. The edges and corners of the push head 130 are all configured to be rounded. The inverted L-shaped structure facilitates the pushing of steel.

[0034] Please refer to Figure 5 As shown, the water tank 210 includes a water storage tank 211 and a water collection slope 212. The water storage tank 211 is placed in the installation cavity 113. The water collection slope 212 is fixedly connected to the upper side of the water storage tank 211. The water collection slope 212 has a certain slope, and the top of the water collection slope 212 is located on the side of the billet heating machine 160. After the spraying part 240 sprays the coolant outward, the coolant flows along the push head 130 to the water collection slope 212, and then gradually flows into the water storage tank 211 according to the water flow effect, completing the coolant recovery. A filter screen 213 is provided at the opening of the water storage tank 211. The filter screen 213 prevents debris from entering the water storage tank 211 and contaminating the coolant. Self-locking sliding wheels 214 are evenly connected to the bottom of the water storage tank 211, and a push-pull hook 215 is fixedly connected to the outside of the water storage tank 211. The self-locking sliding wheel 214 and the push-pull hook 215 cooperate with each other to facilitate dragging the water storage tank 211, thereby facilitating cleaning of the water storage tank 211 and the filter screen 213.

[0035] Please refer to Figure 6 and Figure 7As shown, the spray member 240 includes a fixing frame 241, a spray pipe 242, and a spray nozzle 243. One end of the fixing frame 241 is fixedly connected to both sides of the spray pipe 242, and the other end of the fixing frame 241 is fixedly connected to both sides of the push head 130. The spray nozzle 243 is evenly connected to the spray pipe 242, and the output port of the spray nozzle 243 is directly opposite the push head 130. Through the water outlet 140 and the water pump 220, the coolant flows into the spray pipe 242, so that the spray nozzle 243 sprays the coolant, so that the coolant can constantly cool the push head 130.

[0036] In summary, the working principle of a steel pushing device for rolling mill push of the embodiment of the present invention is as follows: coolant is added into the water storage tank 211, and during production and processing, the water pump 220 is started to allow the coolant to enter the spray pipe 242 through the water outlet hose 230, and part of the coolant is sprayed onto the push head 130 by the spray nozzle 243, so that the push head 130 always maintains a relatively low temperature state, and the coolant that is not completely squeezed out and sprayed returns to the water storage tank 211 for reuse through the return hose 250. In addition, the sprayed coolant can also be collected by the water collection slope 212 and returned to the storage tank. The coolant is reused in the water tank 211 until it can no longer be reused. The coolant is sprayed through the spray nozzle 243 to cool the push head 130, and the return hose 250 and the water flow characteristics can be used to reuse the coolant, so that the push head 130 can be continuously cooled during the production process, so that the hydraulic cylinder is also in a normal temperature range, avoiding the problem in the prior art that the push plate continues to heat up due to the influence of the heating furnace and the steel temperature, and the hydraulic cylinder is affected by the high temperature due to the heat conduction effect, resulting in heat damage to the hydraulic cylinder components and reduced service life of the device.
