Abstract
The utility model discloses a continuous water-cooling system for producing straight-seam high-frequency welded steel pipes with high strength and high cleanliness. The continuous water-cooling system is arranged on a steel pipe production line and is positioned behind a high-frequency welder; the continuous water-cooling system comprises a sizing roll, a cooling groove and a transmission roller; the sizing roll is arranged at the side of the cooling groove close to the high-frequency welder; the transmission roller is arranged at the side of the cooling groove far away from the high-frequency welder; a baffle plate is arranged at each of the two ends of the cooling groove; each baffle plate is provided with a U-shaped hole; a water inlet pipe is arranged on the cooling groove; a recycling pool is arranged below the cooling groove; and the recycling pool is connected with the water inlet pipe through a pipeline with a pump. Cooling water is circulated between the cooling groove and the recycling pool. The cooling water enters the cooling groove from the water inlet pipe, overflows from the U-shaped holes at the two ends of the cooling groove after the cooling groove is fully filled, flows into the recycling pool below the cooling groove, and is pumped to the water inlet pipe through the pipeline with the pump so as to move in circles. According to the continuous water-cooling system, the strength and the cleanliness of the straight-seam high-frequency welded steel pipes can be effectively improved under the condition of continuous high-speed production.
Description
Technical fieldThe utility model relates to the metal advanced machining technology, relates in particular to the continuous water-cooling system of production high strength, high-cleanness, high vertical masonry joint high-frequency welding steel pipe.
Background technologyVertical masonry joint high-frequency welding steel pipe is that the strip steel band with certain specification is rolled into the pipe shape and with its steel pipe of processing through the high-frequency welding technology.The characteristics of this steel pipe's production method are that speed of production is fast, and its charging and discharging all are successional, utilize cutting machine continuous steel pipe to be cut into the steel pipe of certain-length again after the welding.How operations such as continuous completion welding in the extremely short time, deburring, sizing, quenching, cleaning are directly connected to the production efficiency and the product quality of vertical masonry joint high-frequency welding steel pipe, also are the emphasis that this area studies for a long period of time.
According to " process technology of overlength metalwork " (137 sections) in " the high-technology field catalogue that state key is supported " four, new material technology---(one) metal material---10, the advanced preparation of metal material, processing and the forming technique; And 2, " improve the iron and steel cleanliness factor in high-performance metal materials and the specific alloy manufacture of materials technology; The high-strength metal material manufacturing technology " (129 sections) further specify country and encourage enterprise to carry out the improvement and the research of this respect.
Summary of the inventionThe purpose of the utility model provides the continuous water-cooling system of the high production high strength of a kind of working (machining) efficiency, high-cleanness, high vertical masonry joint high-frequency welding steel pipe; This technology can effectively improve the intensity and the cleanliness factor of vertical masonry joint high-frequency welding steel pipe under the situation that continuous high speed is produced, meet the requirement of " the high-technology field catalogue that state key is supported ".
For realizing above-mentioned purpose; The continuous water-cooling system of the production high strength of the utility model, high-cleanness, high vertical masonry joint high-frequency welding steel pipe is arranged on the pipe production line and is positioned at after the high-frequency welder, and it comprises size rolls, cooling bath and live-roller, and described size rolls is arranged at the side of cooling bath near high-frequency welder; Described live-roller is arranged at the side of cooling bath away from high-frequency welder; The two ends of described cooling bath are provided with baffle plate, offer the U-shaped hole on the baffle plate, and described cooling bath is provided with water inlet pipe; The below is provided with recovery pond, and recovery pond is connected with the pipeline of water inlet pipe by the band pump.Cooling water circulates between cooling bath and recovery pond.In cooling water gets into cooling bath from water inlet pipe, overflow from the U-shaped hole at two ends after filling with cooling bath, flow in the recovery pond of below, the pipeline of band pump is drawn to water inlet pipe with the cooling water in the recovery pond again, moves in circles.
Adopt above design; Steel pipe passes through in the middle of the size rolls, and size rolls machines away unnecessary metal from both direction extruding steel pipe body up and down; Steel pipe behind the sizing gets into cooling bath by the U-shaped hole of cooling bath one end-stopping plate and is passed by the U-shaped hole of other end baffle plate, in the middle of live-roller, passes through again.Owing to fill with cooling fluid in the cooling bath; Therefore and cooling fluid is constantly overflowed from the U-shaped hole, and the steel pipe through cooling bath is partly cooled off fully and cleans, and makes steel pipe reach the effect of a quenching; Its intensity improves greatly, and the steel surface cleanliness factor also gets a promotion.Because steel pipe is successively to pass through cooling bath, so its production efficiency is high, produces and can not interrupt.
The bottom land of the cooling bath of the utility model offers the discharge outlet of band valve.In cooling bath, piled up more iron filings, can open scupper valve, the sewage in the discharging cooling bath, the cooling water that more renews.
In sum; Compared with prior art; The utility model can effectively improve the intensity and the cleanliness factor of vertical masonry joint high-frequency welding steel pipe under the situation that continuous high speed is produced; Meet " state key support high-technology field catalogue " 129 sections fully and improve iron and steel cleanliness factor and high-strength metal material manufacturing technologies, and 137 sections are used for the technological requirement of processing super long metalwork.
Description of drawingsBelow in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation:
Fig. 1 is the structural representation of the continuous water-cooling system of the utility model production high strength, high-cleanness, high vertical masonry joint high-frequency welding steel pipe;
Fig. 2 is the structural representation of cooling bath baffle plate in the utility model.
The specific embodimentShown in Fig. 1 or 2; The continuous water-cooling system of the production high strength of the utility model, high-cleanness, high vertical masonry joint high-frequency welding steel pipe is arranged on the pipe production line and is positioned at after the high-frequency welder, and it comprises size rolls 1, cooling bath 2 and live-roller 3, and described size rolls 1 is arranged at the side of cooling bath 2 near high-frequency welder; Described live-roller 3 is arranged at the side of cooling bath 2 away from high-frequency welder; The two ends of described cooling bath 2 are provided with baffle plate 21, offer U-shaped hole 22 on the baffle plate 21, and described cooling bath 2 is provided with water inlet pipe 4; The below is provided with recovery pond 5, and recovery pond 5 is connected with the pipeline 6 of water inlet pipe 4 by the band pump.Cooling water circulates between cooling bath 2 and recovery pond 5.Cooling water gets in the cooling bath 2 from water inlet pipe 4, fills with cooling bath 2 backs and overflows from the U-shaped hole 22 at two ends, flows in the recovery pond 5 of below, and the pipeline 6 of band pump is drawn to water inlet pipe 4 with the cooling water in the recovery pond 5 again, moves in circles.
