Description

The cooling device of lap siding cold-forming shapes milling train

The utility model is the cooling device that is used for the cold-forming shapes milling train.

Here said cold-forming shapes master is meant cold-rolled forming section, is the steel that steel plate, the clod wash of band steel become definite shape, comprises the cold-forming shapes made from carbon steel and stainless steel.Be raw material with lap siding clod wash mill milling cold-rolled forming section with the band steel be that batch is made effective and efficient manner, claim that usually this cold-rolled forming section is a cold-forming shapes.

A kind of typical application of cold-forming shapes is to adopt bar section of stainless steel to make Door or window made of stainless steel and glass curtain wall.Used bar section of stainless steel is made with lap siding cold-forming shapes milling train.Because more very, moulding is more difficult than the resilience of carbon steel and flow harden for stainless steel, the surface is if there is scratch to be difficult to recover former state.So the performance requirement to the cold-forming shapes milling train is also higher.

With the band steel is that the lap siding cold-forming shapes milling train of raw material all is the long-time continuous operation, and the heating of roll and wearing and tearing are bigger, thereby influence the life-span of roll and the quality of section bar product, and situation is just even more serious during particularly rolling bar section of stainless steel.Yet the current domestic milling train that is used for rolling cold-forming shapes comprises the milling train of rolling stainless steel door window profile all not having cooling device, so that roll wear is big, the life-span is short, the shaping of section bar and surface quality are also influenced.

The purpose of this utility model provides the cooling device of lap siding cold-forming shapes milling train, and this installs easy to use adjustable, is used for the cooling of rolling mill roll and work, reduces the heating and the wearing and tearing of roll, improves roll campaign and section bar product quality.

Lap siding cold-forming shapes milling train is made up of a feed end support, many intermediate stands and a forming ends support, and two rollers of pushing aside are installed in the centre position of support on the base, and the roll on the intermediate stand all is paired.

The cooling device of the utility model cold-forming shapes milling train designs for lap siding cold-forming shapes milling train, and a water pump and a cyclic water tank respectively are housed in the base of feed end support and forming ends support.The water inlet of water pump and cyclic water tank UNICOM.A feed pipe is drawn towards support from pump outlet, flexible fairlead and feed pipe UNICOM are arranged on each support, the other end of flexible fairlead connects adjustable water saving and chews, corresponding under flexible fairlead and the roll water dish being arranged, water dish and return pipe UNICOM, return pipe again with cyclic water tank UNICOM.

In the utility model cooling device, feed pipe and return pipe disconnect separately and are divided into two groups, can be to distinguish water pump of UNICOM and a cyclic water tank separately, that is form a cover circulating cooling system separately, and two cover circulating cooling systems are arranged in the complete machine.Also can be the water pump at feed pipe two ends UNICOM two ends, the cyclic water tank at return pipe two ends UNICOM two ends has only a cover circulating cooling system in the complete machine.Because few about 30 breaker rolls of person of lap siding cold-forming shapes milling train, nearly approximately 60 breaker rolls of many persons so cooling system adopts above-mentioned which kind of pattern, can be selected according to actual conditions and operational effect.Fortunately an end of flexible fairlead has adjustable water saving to chew, and switch and adjusting cooling water inflow change cool position easily.Cooling medium can be pure water or emulsion.

In addition, position about cyclic water tank is respectively equipped with filling opening and blowoff valve.Backwater joint is arranged at the bottom of the water dish, in this backwater joint, screen pack is arranged.Water dish is by backwater joint and return pipe UNICOM.In the connecting of feed pipe and return pipe and flexible fairlead and backwater joint, used pipe joint commonly used, as threeway etc.

Fig. 1 is the utility model cooling device unit installation site of member in lap siding cold-forming shapes milling train.Two intermediate stands have only drawn among the figure.

Fig. 2 is the utility model lap siding cold-forming shapes rolling mill refrigerating mechanism schematic diagram, and a water pump and a cyclic water tank have only drawn among the figure.

An embodiment of the present utility model as shown in Figure 2, the water inlet UNICOM cyclic water tank 21 of a water pump 11, feed pipe 31 is drawn from the delivery port of water pump 11, and some flexible aqueducts 33 are connected with feed pipe 31, and the outlet of flexible aqueduct 33 connects adjustable water saving and prevents 35.Chewing corresponding to flexible aqueduct 33 and adjustable water saving has water dish 43 under 35, backwater joint 45 is housed on the water dish 43, screen pack (not drawing among the figure) is housed in the backwater joint 45, and water dish 43 is by backwater joint 45 and return pipe 41 UNICOMs, and return pipe 41 is connected cyclic water tank 21.Filling opening 23 is arranged on the top of cyclic water tank 21, and sewage draining exit 25 is arranged at the bottom.Fig. 2 only drawn a water pump 11 and a cyclic water tank 21.Feed pipe 31 and return pipe 41 are expressed as the state that segmentation disconnects.In fact, water pump and cyclic water tank are provided with as required.For the milling train that tens of breaker rolls are arranged, two water pumps and two more flexible being suitable for of cyclic water tank often are set.

The utility model cooling device be installed on the lap siding cold-forming shapes milling train an example as shown in Figure 1.The cold-forming shapes milling train is by feed end support 51, and intermediate stand 55 (only schematically shown two among the figure, wherein is equipped with motor and reduction box) and forming ends support 52 assemble.In the centre position of support, roll 53 is installed on the base, the part roll and the roll on the forming ends support 52 on feed end support 51, the roll on the intermediate stand 55 all is paired parallel installation.In fact, the intermediate stand of whole milling train more than two, is just illustrated often here.

Cooling device in the milling train shown in Figure 1 is such: water pump 11 and cyclic water tank 21 are housed in the base of feed end support 51, water pump 12 and cyclic water tank 22 are housed in the base of forming ends support 52.
