Abstract

The invention relates to an air valve cutting machine. The air valve cutting machine comprises a lathe body, a chuck, a cutting knife rest, a material distribution cylinder, a material receiving device, a material pushing device and an automatic control system. The air valve cutting machine ensures that the overall length of cut air valves keep consistent; in addition, an automatic machining process is realized, the production efficiency is improved, the production cost is reduced, and labor intensity is lightened.

Description

A kind of valve cuts off machine

Technical field

The present invention relates to a kind of lathe, especially relate to a kind of valve and cut off machine.

Background technology

Present domestic valve manufacturer adopts three kind of method: first kind is that method is cut off in manual work; Use a special use to cut off lathe and be datum level location with the valve retainer conical surface, with the bar portion of collet clamping valve, rod end is unsettled to carry out feeding with hand to knife rest it is cut off operation; This method is tradition relatively; The error of length overall is bigger, and following road grinding rod end operation is caused very big influence, brings inconvenient machining.Second kind is the emery wheel patterning method, and the method exists the inconsistent situation of length equally, and the product rod end of cutting has the metal flange; Make troubles to next procedure, this quadrat method causes production cost to increase substantially using the emery wheel amount big especially; Like this processing method danger is bigger in addition, and diameter of phi 350MM is thick, and grinding wheel is cracked hurts sb.'s feelings in order under the very high situation of the emery wheel on-line velocity of 2MM the product cutting of its Φ 9MM path is easy to cause. and the third is that punch press thrusts method, valve is placed in the open die V-shaped groove on the base frame face of punch press; Baseplane band one spring bearer plate of drift, when the mold mouth on the drift touched product, pressing plate just killed the bar portion of product; Thereby cut, this method, the valve rod end of cutting also has a kind of jade to fall into; The one, bring to next procedure not make, the 2nd, serious directly cause boom end that crackle is arranged and cause waste product. our company adopts is first kind and the third recited above, has wasted great amount of manpower; Material resources, financial resources.

Summary of the invention

Technological technical problem to be solved by this invention provides a kind of valve and cuts off machine, and this lathe can guarantee that not only the length overall of the valve that cuts is consistent, and the process automation, has improved production efficiency, has reduced production cost, has alleviated labour intensity.

For solving the problems of the technologies described above, valve of the present invention cuts off machine, comprises lathe bed, cutter saddle, machine tool chuck, sub-material cylinder, material-receiving device, material-pulling device and control system.

Under the control of control system; Valve falls into material-receiving device through the sub-material cylinder; Material-pulling device pushes machine tool chuck to the valve in the material-receiving device; The lateral attitude of valve in chuck is with the relative chuck of valve retainer conical surface location, and machine tool chuck clamps engine valve stem and rotation then, and the cutter saddle feeding is cut off processing to valve.

Because the lateral attitude of valve in chuck is with the relative chuck of valve retainer conical surface location, the relative chuck in the lateral attitude of cutter saddle is also fixed, so valve length overall after cutting off processing is consistent.

As a kind of improvement of the present invention, be provided with chamfering tool rest on the opposite of cutter saddle, after cutter saddle carried out cutting processing to valve, described chamfering tool rest carried out chamfer machining to valve.

Chamfering tool rest is set, and after cutter saddle carried out cutting processing to valve, chamfering tool rest carried out chamfer machining to valve, thereby had solved the problem that leaves overlap after valve cuts.

Description of drawings

Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further detailed explanation.

Fig. 1 cuts off the machine structural representation for valve of the present invention

Fig. 2 is a valve blanking process sketch map of the present invention

Fig. 3 is that the local B of Fig. 2 is to sketch map

Among the figure 1 be lathe bed, 2 for chuck, 3 for cutter saddle, 4 for chamfering tool rest, 5 for stock shelf, 6 for the sub-material cylinder, 7 for material-receiving device, 71 for cylinder, 72 for care feed tray, 73 for the adjustment screw, 8 for cylinder, 9 for discharging cylinder, 10 for the PLC automatic control system.

The specific embodiment

Like Fig. 1, Fig. 2 and shown in Figure 3, valve cutting machine of the present invention comprises lathe bed 1, chuck 2, cutter saddle 3, on the opposite of cutter saddle 3 chamfering tool rest 4 is installed; Coil outer garden and slip into sub-material cylinder 6 through the valve of corase grind through stock shelf 5 through rough turn, bar portion and carry out blanking, material-receiving device 7 comprises cylinder 71, care feed tray 72, adjustment screw 73, and cylinder 71 promotes care feed trays 72 and upwards catches valve; The valve axis was roughly parallel to chuck 2 axis when valve fell into care feed tray 72, and valve garden dish end is away from chuck 2, and the distance that cylinder 71 promotion care feed trays 72 make progress is regulated control by adjustment screw 73; Material-pulling device 8 is a cylinder, and cylinder 8 pushes chuck 2 with the valve of care feed tray 72, and the lateral attitude of valve in chuck is with the relative chuck of valve retainer conical surface location; Chuck 2 clamps valve, and cylinder 8 is return, chuck 2 rotations; Cutter saddle 3 feedings are cut off processing to valve, cut off processing back cutter saddle and return chamfering tool rest 4 feedings; The valve rod end is carried out chamfer machining, and after chamfer machining was accomplished, chamfering tool rest was return; Chuck is opened, and the valve that cylinder 8 will be accomplished processing pushes discharging cylinder 9, and above-mentioned process is under the control of PLC automatic control system 10, to accomplish.

Certainly valve of the present invention cuts off machine and is not limited to the above-mentioned specific embodiment, can change oil cylinder into or is replaced by other equipment that can realize identical function like cylinder, and such conversion all falls within protection scope of the present invention.

Claims

1. a valve cuts off machine, comprises lathe bed, chuck, cutter saddle, it is characterized in that: also comprise sub-material cylinder, material-receiving device, material-pulling device and automatic control system.

2. valve according to claim 1 cuts off machine, it is characterized in that: the opposite at cutter saddle is provided with chamfering tool rest, and after cutter saddle carried out cutting processing to valve, described chamfering tool rest carried out chamfer machining to valve.
