Abstract

The utility model provides special equipment for deep processing black tubes and colored tubes into spiraltrons. The equipment uses the rolling and pressing principle of a skew roller. When the tubes rotate and move forwards, the spiraltrons which sink outside and protrude inside are rolled and pressed. The utility model can be used for continuous production. Moreover, a screw pitch and the length and depth of the spiraltrons can be adjusted freely in accordance with users' different requirements.

Description

Working equipment for spiraltrons

The present invention is a kind of special equipment that black or the deep processing of non-ferrous metal tubing become spiral grooved tube that is used for.

Spiral grooved tube is a kind of broad-spectrum high efficient heat exchanging element, it has been applied in boiler both domestic and external, desalinization, boats and ships, oil, on many heat-exchange apparatus such as chemical industry, the common process equipment of spiral grooved tube is, utilize original lathe to block the two ends of processed tubing, tubing is rotatable, milled head is put at the toolframe place, and milled head is sent to and laterally moved along leading screw, and rolls out helicla flute on steel pipe, therefore productivity ratio is low, one of processing in about 20 minutes, pitch are subjected to leading screw pitch restriction event non-adjustable, and the finished size inaccuracy, especially two light end size is wayward, also want crop after the processing, make metal consumption increase the processing charges height.

Task of the present invention is to overcome above-mentioned shortcoming, and a kind of high efficiency, high accuracy, low consumption, automatic spiral grooved tube processing unit (plant) of controlling that is applicable to the big production of continuity is provided.The present invention can be according to the helicla flute of the outer recessed convex of different light end length, pitch, the depth of thread and the spiral total lengths that require to roll out regulation on tubing of user.

Task of the present invention is achieved in that and adopts four suite face cross roll feed mechanisms, and processed tubing rotation is advanced, and under the effect of milled head, tubing is rolled out the helicla flute of outer recessed convex simultaneously.The inclination angle of adjusting cross roll can change spiral fluted pitch, by changing two detector location, can control helix tube two light end length and helicla flute total length.Change the milled head stroke simultaneously, can change the helicla flute degree of depth again.

The present invention is described in detail below in conjunction with accompanying drawing:

Fig. 1, spiral grooved tube process equipment principle schematic.

Fig. 2, automatic-control block diagram.Fig. 3, send roller, pressure roller tubing relative position figure.

The present invention for what control automatically, is crossed one another by four groups of axis as shown in drawings, turns to identical curved surface cross roll (1), (2), as shown in Figure 1 (top five rollers are drive roll); Four pressure rollers (3) and a milled head (4) constitute, the axis inclination angle of push rolls (1), (2) can arbitrarily change, processed tubing (5) rotates with the rotation of cross roll and advances, handle the forward and back of milled head (4) by detector A control system and move, milled head (4) working portion is half garden shape.When push rolls (1), when (2) rotating, tubing (5) rotates thereupon and advances, the head of tubing (5) cross milled head (4) the position and during near detector (A) detector (A) send signal, when milled head (4) being pressed by automatic control circuit (C) and executing agency (D), previous section is the light end, compress into from milled head (4), on tubing (5), roll out helicla flute, when the head of tubing (5) arrives detector (B), detector (B) sends signal, makes milled head (4) return original position by automatic control circuit (C) and executing agency (D).Aft section then is the afterbody light end of tubing.The relative position of adjusting detector (A) and milled head (4) can obtain the light end of the spiral grooved tube of different length, and the relative position of adjusting between detector (A), (B) can be controlled the spiral fluted total length.

The advance and retreat stroke of milled head (4) also is adjustable, controls the spiral fluted degree of depth when push rolls axis inclination angle hour with this, jumps out of track backer roll such as Fig. 3 for preventing tubing.

Electric Traction of the present invention is adopted electronic speed regulation, to adapt to the deformation requirements of unlike material, different-diameter and different wall tubing.

Advantage of the present invention is: can carry out consecutive production, production efficiency height, improve about 24 times than conventional method, the machining accuracy height, light end and helix length equidimension are accurate, are convenient to control, and be simple to operate, pitch, the helicla flute degree of depth is adjustable, and the processing charges of saving metal is low.

Claims

1, a kind of spiral grooved tube process equipment that is used to process black or non-ferrous metal tubing is characterized in that it is a curved surface by roll surface, the cross one another cross roll of the axis of roller (1) (2); Pressure roll (3) that the axis of roller and processed tubing axis are angled and working position are the milled head (4) of half garden shape and its axis and processed tubing axes intersect fork and the automatic controller of control milled head duty is formed.
