Abstract

The utility model relates to a valve severing device, comprising a machine body, a grip head, a cutting knife rest, a splitting cylinder, a material receiving device, a material pushing device and an automatic control system. The total length of the severing valve is kept constant and the process is automatized, the production efficiency is increased, the production cost is reduced and the labor intensity is lightened.

Description

Valve cuts off machine

Technical field

The utility model relates to a kind of lathe, especially relates to a kind of valve and cuts off machine.

Background technology

Present domestic valve manufacturer adopts three kind of method: first kind is the method for manually cutting off, cutting off lathe with a special use is the datum level location with the valve retainer conical surface, bar portion with 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 processing inconvenience.Second kind is the emery wheel patterning method, 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 is using the emery wheel amount big especially, cause production cost to increase substantially, processing method danger is bigger so in addition, under the very high situation of the thick emery wheel on-line velocity for 2MM of diameter of phi 350MM the product cutting of its Φ 9MM path being easy to cause that grinding wheel is cracked hurts sb.'s feelings. 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 have Kun to fall into, and 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, wasted great amount of manpower, material resources, financial resources.

The utility model content

Technology technical problem to be solved in the utility model 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, the utility model valve 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, 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 utility model, 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 drawings and specific embodiments the utility model is described in further detail.

Fig. 1 cuts off the machine structural representation for the utility model valve

Fig. 2 is the utility model valve blanking process schematic diagram

Fig. 3 is that the local B of Fig. 2 is to schematic diagram

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

The specific embodiment

As Fig. 1, Fig. 2 and shown in Figure 3, the utility model valve cutting machine 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 through rough turn, bar portion slips into sub-material cylinder 6 through the valve of roughly grinding through stock shelf 5 and carries out blanking, material-receiving device 7 comprises cylinder 71, care feed tray 72, adjust screw 73, cylinder 71 promotes care feed tray 72 and upwards catches valve, the valve axis was roughly parallel to chuck 2 axis when valve fell into care feed tray 72, valve garden dish end is away from chuck 2, the distance that cylinder 71 promotion care feed trays 72 make progress is regulated control by adjusting screw 73, material-pulling device 8 is a cylinder, cylinder 8 pushes chuck 2 with the valve of care feed tray 72, the lateral attitude of valve in chuck is with the relative chuck of valve retainer conical surface location, chuck 2 clamps valve, cylinder 8 is return, chuck 2 rotations, cutter saddle 3 feedings are cut off processing to valve, cutting off processing back cutter saddle returns, chamfering tool rest 4 feedings are carried out chamfer machining to the valve rod end, after chamfer machining is finished, chamfering tool rest is return, chuck is opened, and the valve that cylinder 8 will be finished processing pushes discharging cylinder 9, and above-mentioned process is to finish under the control of PLC automatic control system 10.

Certainly the utility model valve 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 as cylinder, and such conversion all falls within the protection domain of the present utility model.

Claims

1. 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.
