Description

Whirlwind mills peeling machine

The utility model relates to and a kind of bar, pipe cylindrical is carried out the device of machining, is particularly suitable for the processing of continuous casting copper pipes base.

Continuous casting copper pipes base surface has oxide layer, before with the continuously cast billet for pipe-making rolling copper pipe, needs that peeling is cut on continuous casting copper pipes base surface and handles, to guarantee the quality of rolling copper pipe.The method that existing peeling machine generally adopts broaching and circular arc to mill is carried out peeling, with this method processing continuously cast billet for pipe-making, cutter need come and go repeatedly could process complete pipe, production efficiency is low, and Chinese patent CN1120988A is though disclose the peeling equipment that a kind of cutter feed once can add carefully and neatly done root pipe, but this equipment also has the following disadvantages: facing cutter is two in 1, adopting, this cutter head structure complexity is difficult for making blade cost height; 2, in a facing cutter, guide sleeves is set, no guide sleeves in another facing cutter, this can make and occur the cutter that shakes when milling the pipe afterbody; 3, the pipe periphery that processes is polygon, and surface quality is not good enough.

The purpose of this utility model be to provide a kind of simple in structure, cost is low, can process pipe portion end to end smoothly, the good peeling machine of pipe circularity that processes.

In order to achieve the above object, the utility model adopts following technical scheme: a kind of whirlwind mills peeling machine, have support, main shaft, mainshaft gear, input gear, power shaft, bearing, in the inner chamber of support by bearing and main shaft and power shaft load, be fitted with preceding guide pin bushing on the support, main shaft is a hollow shaft; The front end of main shaft is by bearing and the load of whirlwind knife bar, and the front end of whirlwind knife bar is fixedly connected with end mill(ing) cutter; The inwall of support is fixed with internal gear, is fitted with the knife bar gear on the whirlwind knife bar, and knife bar direct geared and internal gear mesh or mesh by idle wheel and the internal gear that is installed on the axle of carrier pulley, and axle of carrier pulley is installed on the main shaft.

After adopting said structure owing to adopt whirlwind knife bar and end mill(ing) cutter, rather than adopt baroque in facing cutter and the high blade of cost, thereby make simple in structurely, the end mill(ing) cutter cost is low, and is convenient to adjust and change; Also because preceding guide pin bushing is housed on support, pipe is come the cutter phenomenon of shaking can not occur to pipe centering by preceding guide pin bushing when the processing head, and pipe is come the pipe supporting by hollow main shaft when the processing afterbody, thereby has guaranteed to process smoothly the portion end to end of pipe; Also around the main shaft revolution, promptly around the revolution of the pipe in the main shaft, thereby the whole circumference of pipe is carried out milling when driving the end mill(ing) cutter rotation owing to the whirlwind knife bar again, make the pipe circularity that processes good, quality is good, is suitable for next rolling process.In addition, a feed can process whole pipe from the beginning to the end, and working (machining) efficiency is very high.

Below in conjunction with drawings and Examples the utility model is done explanation in further detail.

Fig. 1 is the structural representation that whirlwind of the present utility model mills peeling machine;

Fig. 2 is a knife bar gears engaged position partial schematic diagram among second embodiment of the utility model;

As shown in Figure 1, whirlwind of the present utility model mills peeling machine, have support (11), main shaft (16), mainshaft gear (20), input gear (12), power shaft (13), bearing (6), pass through bearing (6) and main shaft (16) and power shaft (13) load in the inner chamber of support (11), be fitted with preceding guide pin bushing (1) on the support (11), main shaft (16) is a hollow shaft; The front end of main shaft (16) is by bearing (6) and whirlwind knife bar (5) load, and the front end of whirlwind knife bar (5) is fixedly connected with end mill(ing) cutter (3); The inwall of support (11) is fixed with internal gear (8), is fitted with knife bar gear (7) on the whirlwind knife bar (5), and knife bar gear (7) meshes with internal gear (8) by the idle wheel (9) that is installed on the axle of carrier pulley (10), and axle of carrier pulley (10) is installed on the main shaft (16).Whirlwind knife bar (5) and end mill(ing) cutter (3) have three groups, and five equilibrium is evenly distributed on the main shaft (16), also can adopt versions such as a group, two groups, four groups.To pipe centering, also be fitted with back guide pin bushing (17) for better on the support (11).Also can not establish back guide pin bushing (17).Idle wheel (9) can be 2, and is opposite when at this moment the direction of rotation of end mill(ing) cutter (3) is with 1 idle wheel (9).

As shown in Figure 2, in second embodiment of the present utility model, the inwall of support (11) is fixed with internal gear (8), is fitted with knife bar gear (7) on the whirlwind knife bar (5), direct and internal gear (8) engagement of knife bar gear (7).All the other structures are identical with above-mentioned first embodiment.

As shown in Figure 1, the utility model in use, drive (14) is loaded onto in the outer end of power shaft (13), it can be belt wheel, gear or sprocket wheel, and with drive (14) and drive unit (not drawing) load, also the outer end of power shaft (13) can be passed through key or pin and drive unit (drawing) load, rotate thereby drive power shaft (13), input gear (12), mainshaft gear (20) and main shaft (16).Continuously cast billet for pipe-making (18) is sent into preceding guide pin bushing (1) under the clamping of preceding push rolls (19), by preceding guide pin bushing (1) centering, the cutting zone of upstream end milling cutter (3) again; The rotation of main shaft (16) simultaneously drives whirlwind knife bar (5) and revolves round the sun around main shaft (16) axis, because knife bar gear (7) is by idle wheel (9) and internal gear (8) engagement, or direct and internal gear (8) engagement, thereby drive whirlwind knife bar (5) high speed rotation, be end mill(ing) cutter (3) high speed rotating, the side face of continuously cast billet for pipe-making (18) is carried out milling with whirling cutter.Enter back guide pin bushing (17) again enter the hollow cavity (22) of main shaft (16) through the continuously cast billet for pipe-making (18) of milling peeling after, back guide pin bushing (17) guarantees that to continuously cast billet for pipe-making (18) recurrence centering effect continuously cast billet for pipe-making (18) is adding stablizing of man-hour.Continuously cast billet for pipe-making (18) then enters back pull-out roll (15), by back pull-out roll (15) pulling, make after the peeling continuously cast billet for pipe-making (18) not before the centering of guide pin bushing (1), but the hollow cavity (22) that main shaft (16) are arranged is to the supporting of continuously cast billet for pipe-making (18) or back guide pin bushing (17) is arranged and the hollow cavity (22) of main shaft (16) play supporting role to the continuously cast billet for pipe-making (18) of peeling part jointly, continuously cast billet for pipe-making (18) is still very stable, the cutter phenomenon of can not shaking, whole continuously cast billet for pipe-making (18) once axially sent to, just all peelings successfully from the beginning to the end, the continuously cast billet for pipe-making of milling (18) circularity is good, the milling efficiency height, be particularly suitable for the peeling processing of various elongated pipes, need not to be provided with machine tool guideway, so structure is also very compact.
