Abstract
The utility model relates to a cooling working roller which is composed of a core shaft, a water inlet, a water pipe arranged in the core shaft, and a water outlet, wherein, the middle surface of the core shaft is processed with two spiral grooves, and the sections of the core shaft with the spiral grooves are provided with sleeve barrels; baffle plates are respectively connected with the sleeve barrels and both ends of the core shaft with the spiral grooves, and the water pipe is divided into a water inlet pipe and a water outlet pipe which are not communicated with each other; both ends of the core shaft with the spiral grooves are provided with a water inlet pipes and water outlet pipes of the spiral grooves, wherein, the water inlet pipe of one spiral groove is connected with a water guiding groove of the core shaft, and the water guiding groove is connected with one of the spiral grooves; the corresponding water outlet pipe is connected with the point of the water outlet pipe which has a definite distance with the water outlet pipe of the other spiral groove, and the water outlet pipe of the spiral groove is connected with the water inlet pipe of the water pipe.
Description
The utility model belongs to the working roll of carrying or pinching condition of high temperature material.
Before the invention, the most employing of working roll of carrying or pinching condition of high temperature material is provided with a cooling-water duct at the mandrel center working roll is cooled off.Its deficiency is that the high-temperature zone of roller surfaces can not effectively be cooled off, and makes working roll be in condition of high temperature work, influences its service life.Also have employing to process some water channels in addition on mandrel and make its well-distributed mode cooling work roller, this kind mode is for working roll, though cooling performance is better than aforesaid, but processed complex, and need the cooled water distributor of a special use, and be whole processing, be not easy to repair.
The purpose of this utility model is to overcome above deficiency, a kind of good cooling results is provided, processes novel cooling work roller simple and that be convenient to repair.
The purpose of this utility model be achieved in that main by mandrel, water inlet, be arranged on the novel cooling work roller that water pipe, water outlet in the mandrel are formed, be that the mandrel middle part surface is processed with two plug helixs, for ease of repairing and plug helix being sealed, there is being the spiral fluted mandrel partly to be with sleeve.Baffle plate is respectively with sleeve and there are spiral fluted mandrel two ends to captive joint, water pipe is divided into not connected coolant inlet pipe and coolant outlet pipe, there are being spiral fluted mandrel two ends to be provided with spiral fluted coolant inlet pipe and coolant outlet pipe, one of them spiral fluted coolant inlet pipe is connected the guiding gutter of processing on the mandrel, guiding gutter is connected with plug helix again, corresponding coolant outlet pipe is connected in the coolant outlet pipe place that certain distance is arranged with another spiral fluted coolant outlet pipe, and two spiral fluted coolants inlet pipe are connected on the coolant inlet pipe.For making the working roll cooling performance better, two plug helix arrangement in parallels, flow direction of cooling water expansion tank is reversing sense each other in it.
Principle of work: cooling water expansion tank divides two-way after entering coolant inlet pipe by water inlet, promptly one the road flows into one of them spiral fluted coolant inlet pipe, to the spiral fluted coolant outlet pipe, discharges by the coolant outlet pipe and the water outlet of axle core after plug helix is to the working roll cooling again; Another road then enters another spiral fluted coolant inlet pipe by the coolant inlet pipe of axle core, enters coolant outlet pipe by corresponding spiral fluted coolant outlet pipe again behind the guiding gutter of flowing through and discharges through water outlet.
The utility model is to hot operation roller good cooling results, and processing is simple, owing to not being under the condition of high temperature, working roll do not work, so but prolong its service life, and be convenient to dismounting reparation.
Description of drawings is as follows
Fig. 1 is the structural representation of novel cooling work roller
Fig. 2 M enlarged drawing is the helical groove structure scheme drawing of novel cooling work roller
Be described in further detail below in conjunction with accompanying drawing:
Mainly, be that mandrel (1) middle part surface is processed with two plug helixs (5a, 5b) of arrangement in parallel by mandrel (1), water inlet (2), the water pipe (3) of processing in mandrel (1), the novel cooling work roller that water out (4) is formed.For ease of repairing the sealing that reaches plug helix (5a, 5b), overlap sleeved (6) in mandrel (1) part that plug helix (5a, 5b) is arranged.Baffle plate (7) is respectively with sleeve (6) and there are mandrel (1) two ends of plug helix (5a, 5b) to adopt welding fixing.For preventing that baffle plate (7) produces changing of the relative positions phenomenon with mandrel (1) when moving, so also adopt pin that they are fixed.Water pipe (3) is divided into not connected coolant inlet pipe (8) and coolant outlet pipe (9).For making the working roll cooling performance better, the coolant inlet pipe (10a) of connecting bolt groove (5a) on the coolant inlet pipe (8) of mandrel (1) one end that plug helix (5a, 5b) is arranged, the coolant outlet pipe (11a) of connecting bolt groove (5a) on the coolant outlet pipe (9) of mandrel (1) other end that plug helix (5a, 5b) is arranged.Coolant inlet pipe (10b) connection location of plug helix (5b) is identical with the coolant inlet pipe (10a) of plug helix (5a), and on same axis, and communicates with coolant inlet pipe (8).On the mandrel (1) that plug helix (5a, 5b) is arranged a guiding gutter (12) is arranged vertically, guiding gutter (12) is connected with plug helix (5b), and corresponding coolant outlet pipe (11b) is connected the end of coolant outlet pipe (9) near coolant inlet pipe (8).Current direction in the plug helix (5a, 5b) is reversing sense each other.Above-mentioned water pipe, coolant inlet pipe, coolant outlet pipe, guiding gutter are boring and form.
Principle of work: cooling water expansion tank enters water inlet (2) and two-way is divided in coolant inlet pipe (8) back, i.e. one road coolant inlet pipe (10a) that flows into plug helix (5a), after plug helix (5a) is to the working roll cooling,, discharge by the coolant outlet pipe (9) and the water outlet (4) of mandrel (1) again to the coolant outlet pipe (11a) of plug helix (5a); Another road then enters the coolant inlet pipe (10b) of plug helix (5b) by coolant inlet pipe (8), the coolant outlet pipe (11b) that enters plug helix (5b) by guiding gutter (12) enters coolant outlet pipe (9) again, is discharged by water outlet (4).
