Description

A kind of metal pipe material plate drawing machine cooling device

Technical field

The utility model relates to a kind of metal pipe material plate drawing machine cooling device.

Background technology

Tubing was spirally wound on the dish tube periphery during the metal pipe material dish drew; the continuous rotation of dish tube self; pulling tubing passes through processing mold; after processing mold processing; tubing reaches the product requirement of regulation; hold-down roller is under the promotion of actuator; tubing is pressed on the periphery of dish tube; make and produce enough frictional force between tubing and the dish tube with dish trombone slide material; be pulled through in the journey at dish; when tubing can be because of distortion during by the processing mold machining deformation between atom powerful friction produce a large amount of heats; for avoiding the damage of hold-down roller; need the surface that hold-down roller contacts with tubing is cooled off; existing technology is for adopting the fan wind device for cooling; with fan; hold-down roller is fixedly connected on the actuator; fan blows cooling air to the surface that hold-down roller contacts with tubing; play the effect of cooling; the heat transfer rate of air is slower so on the one hand; heat exchanger effectiveness is lower, and the effect of cooling is bad, and blower fan weight is bigger on the other hand; under the vibration effect that when hold-down roller compresses tubing, produces; be easy to because of loosening or damage cancel closedown, caused the interruption of producing, reduced production efficiency.

Summary of the invention

The purpose of this utility model provides cooling effect and connects firm metal pipe material plate drawing machine cooling device and structure preferably.

For achieving the above object, the technical solution adopted in the utility model is: a kind of metal pipe material plate drawing machine cooling device, described metal pipe material plate drawing machine comprises that providing the dish motive force will coil the trombone slide material by self rotation continuously is wound into dish tube on self periphery, described tubing can be pressed on the described dish tube periphery to produce the hold-down roller that required dish draws frictional force, drive described hold-down roller towards or the actuator that deviates from described dish tube motion, described hold-down roller is driven around self rotating shaft rotation by described dish tube, described hold-down roller has the inner chamber of sealing, two ends of the rotating shaft of described hold-down roller have the duct that is connected with described hold-down roller closed cavity, described cooling device has had first swivel joint and second swivel joint of switching effect, can carry the inlet channel and the outlet conduit of cooling water, one end of described first swivel joint is connected with described inlet channel, the other end is connected with duct, described rotating shaft one end, one end of described second swivel joint is connected with duct, described rotating shaft the other end, the other end is connected with described outlet conduit, in described hold-down roller closed cavity, inserts is set, described inserts has allows that described rotating shaft is passed in inserts through hole wherein, form the but logical crack passage of current of cooling between described inserts and described hold-down roller internal chamber wall, described crack passage one end has inlet, the other end has outlet, offers respectively and described crack feeder connection on two end cell walls of described rotating shaft, first opening that outlet is connected, second opening.

Preferably, offer a pair of locating hole relatively at the center position of described inserts through-hole wall, the alignment pin of fixing described inserts is set, described alignment pin is passed on the described rotating shaft, and described alignment pin two ends are separately fixed in the described locating hole.

Because the utilization of technique scheme, the utility model compared with prior art has following advantage: but logical inlet channel and the outlet conduit of current of cooling is set, the inserts that has the through hole that passes through for rotating shaft in the hold-down roller inner chamber setting of sealing, form the but logical crack passage of current of cooling between inserts and the hold-down roller internal chamber wall, on rotating shaft terminal portion axial direction, offer the but logical duct of current of cooling, on the cell walls of rotating shaft end, offer the opening that is connected with the crack passage, by two swivel joints with rotating shaft duct and inlet channel, outlet conduit couples together respectively, cooling water enters duct, rotating shaft one end by inlet channel through first swivel joint, flow into the crack passage at first opening part, carry out getting back in the duct, rotating shaft the other end by second opening after the heat exchange, after flowing into outlet conduit, second swivel joint drains again, cooling effect is better like this, and because installation weight is light, so connect firm, can not break down and influence production, guarantee higher production efficiency because of vibrating reason such as loosening.

Description of drawings

Accompanying drawing 1 is looked schematic diagram for master of the present utility model;

Accompanying drawing 2 is a side-looking cross-sectional schematic of the present utility model.

The specific embodiment

Further set forth the utility model below in conjunction with accompanying drawing.

Referring to shown in Figure 1, hold-down roller 2 with closed cavity pushes high temperature tubing under the effect of actuator 1, at this moment, the cooling water that inlet channel 3 is carried enters the rotating shaft 7 that has duct, two ends on the axial direction through swivel joint 4, begins hold-down roller 2 is cooled off.

Referring to shown in Figure 2, the utility model adopts two swivel joints, one end of first swivel joint 4 is connected with inlet channel 3, the other end is connected with duct, rotating shaft 7 one end, one end of second swivel joint 6 is connected with duct, rotating shaft 7 the other end, the other end is connected with outlet conduit 5, first swivel joint 4, second swivel joint 6 can make rotating shaft 7 and static inlet channel 3, outlet conduit 5 keeps connecting, guarantee feeding and discharge that cooling water is continual and steady, in hold-down roller 2 inner chambers, be provided with and have the inserts 9 that is passed in through hole wherein for rotating shaft 7, offer a pair of locating hole 10 relatively at inserts 9 through-hole wall center positions, rotating shaft 7 is passed in setting, the alignment pin that two ends match with locating hole 10 respectively, in order to fixing inserts 9, like this when hold-down roller 2 rotations, inserts 9 can rotate synchronously, and relative displacement can not take place in 2 of hold-down rollers, form the but logical crack passage 12 of current of cooling between inserts 9 and hold-down roller 2 internal chamber walls, crack passage 12 1 ends are the but inlet 15 of water inflow of cooling, the outlet 16 of the other end for Gong cooling water flow out of, on the cell walls at rotating shaft 7 both ends, be provided with and inlet 15 first openings 11 that are connected, with outlet 16 second openings 8 that are connected, during cooling, inlet channel 3 carries cooling water to enter in the duct, an end of rotating shaft 7 through first swivel joint 4, cooling water is at first opening, 11 punishment streams, 15 enter crack passage 12 through entering the mouth, increased heat exchange area like this, after cooling water and hold-down roller 2 walls carry out heat exchange, at interflow, outlet 16 places, get back in the duct, the other end of rotating shaft 7 through second opening 8, entering outlet conduit 5 backs by second swivel joint 6 again discharges, flow of cooling water speed is very fast, and heat exchanger effectiveness is higher.
