Description

Tube-cutting machine

The utility model relates to a kind of pipe cutting machine, and the pipe cutting machine of fluid pressure type low noise particularly is applicable in the production, application process of metal tube.

In the production of metal tube, application process, often carry out the disconnected of metal tube and cut, cut on this operation disconnected, be extensive use of sawing at present.This sawing mode is relatively simple, but it has the shortcoming that noise is big, metal fillings is hurted sb.'s feelings easily, and the difficult recovery of metal fillings, causes raw-material waste.Although the saw blade that has improves, used the damping saw blade, operating personnel put on safety device, do not have obvious effects.

The purpose of this utility model is in order to overcome above-mentioned shortcoming, design a kind of novel, easy and simple to handle, applicability wide, a kind of pipe cutting machine of the safe low noise of high efficiency.

To achieve these goals, designed a kind of pipe cutting machine, comprised clamp mechanism, tube cutting mechanism, it is characterized in that:

A, clamp mechanism is by the clamping cylinder that is packed in the clamping cylinder bracket supports on the frame, one end is contained in the oil cylinder head that can horizontally slip in the clamping cylinder, the oil cylinder head connecting rod that is threaded with oil cylinder head front end, the little axle that is connected with connecting rod with oil cylinder head connecting rod, one end is connected with little axle and connecting rod that the other end is connected with camshaft, be bearing in the camshaft on the cam holder, be packed in the cam on the camshaft, slip the link stopper that is contained in the clamp arm bottom hole with cam, withstand on the link stopper with the cam adjustment axle that is threaded in the screw of clamp arm bottom by spring, be bearing in the clamp arm that clamps on the arm axle, be packed in clamping arm axle in the bearing on the frame with bolt, be fixed by bolts to the fixture block of clamp arm in suitable for reading and form.

B, tube cutting mechanism are by the Pipe Cutting oil cylinder that is packed in upper rack, and an end is screwed the upper cutter in the slide block bottom at the in-oil cylinder slide block that can slide up and down of Pipe Cutting, and the planing tool device is formed.

The planing tool device by the adjustment connecting rod that is fixed on the slide block bottom, with connecting rod on hole and the planing tool adjusting minor axis that tie rod holes is connected, be bearing in planing tool dish on the cutter holder axle, be fixed on the planing tool dish with bolt formed.

The blade of upper cutter is:

$y=\sqrt{R^2-X^2}-R\ln \frac{R+\sqrt{R^2-X^2}}{X}$

Symmetrical abnormal logarithmic curve

Wherein R is the radius of processing tube, and x is an abscissa, and y is an ordinate.

Owing to adopted technique scheme, greatly reduce the noise of pipe cutting machine, reduced industrial accident, improved workman's working condition, improved labor productivity, it is block that the metal that otch downcuts becomes, can reclaim, save raw material, have tangible economic benefit and social benefit.

Fig. 1 is the Facad structure schematic diagram of pipe cutting machine.

Fig. 2 is the side structure schematic diagram of pipe cutting machine.

Fig. 3 is the tube cutting mechanism schematic diagram.

Fig. 4 is the abnormal logarithmic curve chart of the blade of upper cutter.

Below in conjunction with description of drawings the utility model is further described.

Behind switch connection, the hydraulic sequence valve of hydraulic circuit is opened automatically, make the rodless cavity of the clamping cylinder (32) that is fixed on the cylinder bracket (33) oil-filled, oil cylinder head (34) and oil cylinder connecting rod (15) beginning advance left, by little axle (13) action is passed to connecting rod (12), connecting rod drives camshaft (11) and the cam (30) that is connected with it with key, outwards opened the bottom of clamp arm (5) by the link stopper (38) that slips with it at the exterior angle on inclined-plane when cam rotated, and makes to be bearing in the suitable for reading of the clamp arm that clamps on the arm axle (8) and with fixed thereon mouthful of interior fixture block (3) of bolt (4) clamping work pieces (37) inwards.Can reach clamping work pieces according to the pipe of work piece through adjustment cam regulating shaft (31).

After workpiece is clamped, pressure in the rodless cavity of Pipe Cutting oil cylinder (18) rises to after the certain value, the hydraulic sequence valve of hydraulic circuit is opened automatically, at this moment, beginning oil-feed in the Pipe Cutting oil cylinder rodless cavity, slide block (19) is moved downward on slideway (1), drive and use screw (20) respectively, nut (35) is packed in upper cutter (25) and the planing tool device on the slide block, can realize two actions, the adjustment connecting rod (21) of first planing tool device moves down under the effect of slide block, by minor axis (22) drivening rod (23), be connected with planing tool dish (26) by minor axis (24), another fulcrum of planing tool dish is to be fixed on cutter holder (2) axle, and planing tool (28) is fixed on the planing tool dish with bolt (27), moves down at slide block like this and just makes that the planing tool movement locus is a garden camber line, when planing tool is surperficial by workpiece (37), stroke on surface of the work and mistake, the degree of depth of streaking is about 1/3 of pipe thickness, has promptly finished the process of planing.Its two be upper cutter under the effect of slide block, follow planing tool closely and dug after the workpiece, the incision workpiece, its workpiece is cut off.When the stroke of Pipe Cutting oil cylinder on earth after, past by electrical control upper cutter and caesium knife system by original this answer of route.Pass through hydraulic sequence valve again, make the clamping cylinder head drive oil cylinder head connecting rod return to the right, oil cylinder head connecting rod rotates by cutting a drivening rod, thereby driving camshaft and cam rotates, cam is resetted, and utilize the spring (29) that is contained in the clamp arm lower end that clamp arm is resetted, thereby finished a process-cycle.Processing later on should repeat above-mentioned course of action.

The name of other part is called upper spider (6), bolt (14), and lower bearing bracket (17), upper cutter frame (36) is adjusted bolt (7), bearing (9), fastening bolt (10), cam holder (16).
