higher owing to just entering the temperature for the treatment of sizing body of sizing unit, need concentrated, cooling rapidly, so, be less than near the distance between the two adjacent fins 6 of end plate 9 near the distance between the two adjacent fins 6 of front end-plate 8, and a kind of preferred structure is from front end-plate 8 backward the direction of end plate 9, distance between two adjacent fins 6 increases gradually, can ensure that the cooling effect of the each branch of body approaches, and avoids the part difference of color, the lines etc. of body.
above-mentioned spray module 11 comprises the water inlet being opened on urceolus 10, be arranged on the water inlet shower nozzle 14 of water inlet, be located at into the water-locator 15 at water shower nozzle 14 places, as shown in Figure 4, a side towards fin 6 of water-locator 15 offers multiple hole for water sprayings 16, be not less than the distribution length of these fins 6 along the water spray cascade unit for the treatment of these hole for water sprayings 16 in direction that sizing body moves, and in order to ensure the controllability of hydraulic press water temperature, on urceolus 10 along treating to offer two water inlets in direction that sizing body moves, each water inlet is all provided with into water shower nozzle 14 and water-locator 15, and the discharge pressure of the water inlet shower nozzle 14 of close front end-plate 8 is greater than the discharge pressure near the water inlet shower nozzle 14 of end plate 9, and, from front end-plate 8 backward the direction of end plate 9, the distribution density of hole for water spraying 16 reduces gradually, like this, the distance of comprehensive fin 6 from the near to the remote, hole for water spraying 16 by close to dredge, the body that just enters sizing unit is cooled rapidly, improve overall cooling effect.
the water that hole for water spraying 16 upwards sprays, the gap between fin 6 and fin 6 having is sprayed directly on to the outer wall of body, directly carry out cooling to body, what have is sprayed on fin 6, the temperature of fin 6 is lowered, and the fin 6 that area is larger can be realized rapid heat radiation, then indirectly carry out cooling to body by the fin 6 of low temperature.
urceolus 10 upper walls be provided be connected to vacuum source can be to the vacuumizing joint 17 vacuumizing in urceolus 10, like this, in water spray, vacuumize (above-mentioned sealing setting everywhere vacuumizes in order to realize exactly) in to urceolus 10, water rolling in urceolus 10 is stirred, farthest make fin 6 and the body various aspects can both be rapid by the water of low temperature, cooling fully, be conducive to improve cooling effect, simultaneously, vacuumize and make hose expansion, , through-hole wall on the outer wall of body and fin 6 relatively moves and rubs, realize the outer wall polishing to body, improve the smoothness of tube wall face.
between above-mentioned front end-plate 8 and end plate 9, be strained and fixed mutually by least two locking pull bars 18, on front end-plate 8, offer locking hole, on end plate 9, offer locking screw pit, locking pull bar 18 two ends have respectively external screw thread, locking pull bar 18 is tightened in the locking screw pit on end plate 9 through locking hole screw thread on front end-plate 8, on one end outside front end-plate 8, screw a nut being exposed at of locking pull bar 18, make like this front end-plate 8 and end plate 9 axial lockings, and clamp positioning spacer 13 and the fin 6 on the backstay 7 between them, prevent from occurring in the course of work axial play.
in addition, the guiding bellmouth that the through hole at front end-plate 8 centers passes for ease for the treatment of sizing body, and in the minimum of this guiding bellmouth, warp is identical with the aperture of the through hole on fin 6.
the below of preposition water cooling unit is provided with the water drain funnel that catchments, for collecting and discharge the water outlet of preposition water cooling unit and a small amount of water that sizing unit overflows.
above-mentioned water collar 1 is copper, and fin 6 is stainless steel.
to sum up, more traditional method has improved the cooling effect of body greatly, when therefore application the design's diameter-setting equipment carries out sizing, can improve the speed of feeding body, the body feed speed of original diameter-setting equipment is generally at 5～6m/min, and the design's device, in the time that feed speed reaches 20～25m/min, can reach suitable cooling effect, therefore solved the problem of the restriction of sizing link to body speed of production.
in design of the present invention, edge treats that the moving direction of sizing body is distributed with fin 6 and the hole for water spraying that density reduces gradually, water be sprayed directly on on tube wall or fin 6 on, directly carry out cooling to body, or indirectly carry out cooling to body by the fin 6 that has been lowered temperature, because the area of fin 6 is larger, effectively improve cooling effect, like this, in the time that one section of current body has just entered sizing unit, under the mating reaction of the cooling water spraying at intensive hole for water spraying and intensive fin 6, obtain rapidly cooling, again successively under the cooling effect through more sparse fin below and hole for water spraying, simultaneously, under the effect vacuumizing, cooling water rolling in urceolus is stirred, the all directions that ensure body all can reach cooling effect, and then effectively improve the production efficiency of body.
above-described embodiment is only explanation technical conceive of the present invention and feature, and its object is to allow person skilled in the art can understand content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences that spirit is done according to the present invention change or modify, within all should being encompassed in protection scope of the present invention.
