Description
The utility model relates to a kind of device of rolled metal tubing, the rolling tube equipment of especially relevant rolling copper and copper-alloy pipe-material.
Existing three-roller planetary pipe mill is when tube rolling, water is sprayed on breaker roll cools off on the roll, though can control the temperature rise of roll so to a certain extent, but the deformed area temperature to tubing is difficult to control, thereby be prone to the tubing unstable phenomenon that produces because of the deformed area temperature is too high, or occur crossing the low incomplete phenomenon of crystallization again that produces because of the deformed area temperature, cause pipe workpiece quality to descend; In addition, tubing is rolling in air, and because of operation of rolling temperature rise makes the tube surfaces severe oxidation, influence is processing or use further.
But the three-roller planetary pipe mill that the purpose of this utility model is to provide a kind of control valve material deformed area temperature and can prevents the tube surfaces oxidation.
In order to achieve the above object, the utility model adopts following technical scheme: a kind of three-roller planetary pipe mill, have support, charging center and roll and roller drive set, the roll side of support is fixedly connected with nose shell, be provided with protective gas air inlet, sparge pipe and delivery port in the nose shell, the outer end of nose shell is fixedly connected with the water seal cooling device; The water seal cooling device is by water inlet pipe, overflow water jacket, guide ring, backwater elbow, and water leg and nose shell wall are formed; The opposite side of support is fixedly connected with torque motor or hydraulic motor, and reduction box and chain sprocket transmission mechanism, is fixedly connected with carrying roller on the chain and sends dolly to.
After adopting said structure, because the roll side at support is fixedly connected with nose shell, the tube rolling process is carried out in nose shell, directly spray water in rolling to tubing deformed area water spray with to roll, can control rolling temperature, opposite side at support is provided with the carrying roller that is driven by torque motor and sends dolly to simultaneously, they send tubing to roll reposefully with the thrust of setting, temperature rise is changed to be reduced, thereby tubing deformed area temperature is further controlled, unstability or the incomplete phenomenon of crystallization more can not appear in the tubing after rolling, can guarantee steady quality, the performance unanimity; Also owing in nose shell, be provided with the protective gas air inlet; injecting protective gas from this air inlet can make the operation of rolling carry out at protective gas all the time; avoided contacting with air; thereby make the tube surfaces after rolling not oxidized; having added the water seal cooling device further cools off tubing; just from pipe mill, come out after making tubing cool to room temperature scope; so with the rolling tube surfaces light of three-roller planetary pipe mill of the present utility model; the non-oxidation phenomenon is convenient to further processing or use.In addition, roll also is difficult for oxidation, corresponding raising in service life.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the structural representation of three-roller planetary pipe mill of the present utility model;
Fig. 2 is the cutaway view of Fig. 1 along A-A line;
Fig. 3 is the cutaway view of Fig. 1 along B-B line.
As shown in Figure 1, three-roller planetary pipe mill of the present utility model, have support (18), charging center (10) and roll (8) and roller drive set, the roll side of support (18) is fixedly connected with nose shell (6), be provided with protective gas air inlet (30), sparge pipe (7) and delivery port (19) in the nose shell (6), the outer end of nose shell (6) is fixedly connected with water seal cooling device (5); Water seal cooling device (5) is made up of water inlet pipe (24), overflow water jacket (3), guide ring (2), backwater elbow (23), water leg (1) and nose shell (6) wall; The opposite side of support (18) is fixedly connected with torque motor (16) or hydraulic motor, and reduction box (17) and chain sprocket transmission mechanism (11), is fixedly connected with carrying roller (12) on the chain (14) and sends dolly (15) to.For the ease of installation and maintenance, the bottom of nose shell (6) is equipped with roller (20), can open or close nose shell (6) easily like this.Sparge pipe (7) links to each other with nose shell (6) water inlet pipe (22) outward.In order to control tubing deformed area temperature better, can be with sparge pipe (7) and flowmeter load, its sample just can be according to the changes in flow rate of water, the controlled rolling temperature.Be circumscribed with water seal elbow (21) at delivery port (19), thereby prevented that air from entering in the nose shell (6) from delivery port (19).Overflow water jacket (3) has overflow window (4).
As shown in Figure 2, send to and have charging ram (13) and chute (26) on the dolly (15), this chute (26) is slidingly matched with guide rail (25) on the support (18).Be fixed with chain holder (27) on the support (18) of chain (14) below.
As shown in Figure 3, carrying roller (12) is double being installed in side by side on the carrier roller frame (29), has slide block (28) on the carrier roller frame (29), and the guide rail (25) on this slide block (28) and the support (18) is slidingly matched, and carrier roller frame (29) is fixed on the chain (14).
As shown in Figure 1, when the utility model uses, torque motor (16) and reduction box (17) drive chain sprocket transmission mechanism (11) and rotate, carrying roller (12) holder that is fixed on the chain (14) carries tubing (9), the dolly (15) of sending to that is fixed on the chain (14) is then together advanced by chain (14) drive, charging ram (13) advances charging center (10) with tubing (9), and enters the working region of roll (8); Simultaneously, roll (8) rotates under the drive of roller drive set, and tubing (9) is rolled.Sparge pipe (7) cools off and controls the temperature of tubing (9) deformed area facing to the deformed area water spray of roll (8) and tubing (9).Injection flow rate can be controlled by flowmeter.In the operation of rolling, protective gas air inlet (30) is given in the nose shell (6) and is charged into restitutive protection's gas, and the outlet of this gas is charging center (10).Restitutive protection's gas is generally mixed by 3～30% hydrogen and 70～97% nitrogen, and the operation of rolling is carried out under the situation that no air enters all the time, and this makes that tubing (9) surface is not oxidized.Tubing after rolling (9) enters cooling in the water seal cooling device (5) subsequently, and in water seal cooling device (5), water enters overflow water jacket (3) and is full of from water inlet pipe (24).Sub-fraction water flows out through the gap of guide ring (2), and an end flows directly in the water leg (1), and the other end flows in the water leg (1) through backwater elbow (23).Water a large amount of in the overflow water jacket (3) flow into water leg (1) through overflow window (4).Tubing (9) obtains the cooling of current by overflow water jacket (3) time, and tubing (9) is embedded in the water and do not contact with air, thus rolling tubing (9) surface-brightening that comes out, non-oxidation, quality is good.
