Abstract

The invention discloses a dedicated device for pipe fitting tail end forming, and particularly discloses a pier head machine. The pier head machine comprises an engine base, wherein a pier head die and an oil cylinder capable of driving the pier head to move front and back are arranged on the engine base; a lower fixed die is arranged in front of the pier head die; a lower slide die capable of sliding in the lower fixed die front and back is arranged in the position opposite to the pier head die and in the lower fixed die; placement grooves capable of placing pipe fittings to be processed are formed in the lower fixed die and the lower slide die; after the pipe fittings to be processed are placed in the placement grooves, pipe mouths of the pipe fittings directly face to the pier head center position of the pier head die; an upper pressing die driven by a compression cylinder is arranged above the lower fixed die; and the upper compression die can compress the pipe fittings to be processed under the driving of the compression cylinder. With the structure, compared with general forming machines, the pier head machine has the advantages of convenience and rapidness in processing and easiness in operation, can meet higher strength requirement, and is longer in service life.

Description

The pier nose machine

?

Technical field

The present invention relates to the special equipment of the terminal moulding of a kind of pipe fitting, specifically a kind of pier nose machine.

Background technology

In the prior art, engineering some joint pipe fittings of parts, tube wall that usually need the joint pipe fitting is provided with outwards outstanding annular projections of a section or two sections, in order to be connected with other counterpart, usually all be to adopt a kind of make-up machine to its machine-shaping for arranging of this structure, existing this former, because structure arranges unreasonable, not only manufacturing cost higher and also in process processing technology more complicated, operating difficulties, processing intensity for pipe fitting is not high, is difficult to satisfy actual instructions for use.

Summary of the invention

The technical problem to be solved in the present invention provides a kind of simple in structure, and is easy to process, quick, processing ease and have the pier nose machine in long service life.

In order to solve the problems of the technologies described above, pier nose machine of the present invention, comprise support, support is provided with the pier nose mould and can drives the oil cylinder that the pier nose mould moves forward and backward, the place ahead of pier nose mould is provided with a fixedly counterdie, fixedly in the counterdie and the position relative with the pier nose mould be provided with one can be in fixing counterdie before and after the slip counterdie of slip, fixedly be provided with the resettlement groove that to place pipe fitting to be processed in counterdie and the slip counterdie, pipe fitting to be processed makes the mouth of pipe of pipe fitting over against the pier nose center of pier nose mould after being placed in the resettlement groove, fixedly the top of counterdie is provided with a top die that is driven by clamping cylinder, and top die can compress pipe fitting to be processed under the driving of clamping cylinder.

Described pier nose mould is arranged side by side two, and fixedly the below of counterdie is provided with and can makes the fixedly guiderail base of counterdie move left and right, can make fixing counterdie be in the dead ahead of any one pier nose mould according to the difference of pipe fitting diameter to be processed.

The pier nose center of described pier nose mould is provided with the groove of taper.

After adopting above-mentioned structure, because the pier nose mould that moves forward and backward that arranges and the fixedly counterdie that is positioned at pier nose mould the place ahead, fixedly be provided with the slip counterdie that slides before and after can be in fixing counterdie in the counterdie, arrange in the course of the work thus, by hydraulic oil cylinder driving pier nose mould workpiece to be processed is pushed, form annular projection between the counterdie and slip counterdie making under the effect of slip counterdie fixedly, the pier nose mould part also forms an annular projection simultaneously, arrange thus, compare with general make-up machine have easy to process, fast, the advantage of processing ease can satisfy higher requirement of strength, has long service life.

Description of drawings

Fig. 1 is the perspective view of pier nose machine of the present invention;

Fig. 2 is the A place structure for amplifying schematic diagram of Fig. 1.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, pier nose machine of the present invention is described in further detail.

As shown in the figure, pier nose machine of the present invention, comprise support 1, support 1 is provided with pier nose mould 2 and can drives the oil cylinder 3 that the pier nose mould moves forward and backward, the place ahead of pier nose mould 2 is provided with a fixedly counterdie 4, in fixing counterdie 4 and the position relative with pier nose mould 2 be provided with a slip counterdie 5 that slides before and after can be in fixing counterdie 4, fixedly be provided with the resettlement groove 7 that to place pipe fitting 6 to be processed in counterdie 4 and the slip counterdie 5, pipe fitting 6 to be processed makes the mouth of pipe of pipe fitting over against the pier nose center of pier nose mould 2 after being placed in the resettlement groove 7, fixedly the top of counterdie 4 is provided with a top die 8 that is driven by clamping cylinder, and top die 8 can compress pipe fitting to be processed 6 under the driving of clamping cylinder.

Further also pier nose mould 2 can be arranged side by side two, fixedly the below of counterdie 4 is provided with and can makes the fixedly guiderail base 10 of counterdie move left and right, can make fixing counterdie 4 be in the dead ahead of any one pier nose mould 2 according to the difference of pipe fitting diameter to be processed, the groove that the pier nose center of one or two pier nose moulds that can also be therein is provided with taper has satisfied the demand with pyramidal structure pipe fitting.

During use, at first to clamp the tube wall of pipe fitting to be processed with fixedly counterdie and slip counterdie, drive the lower pressed film that is driven by clamping cylinder then, it is pressed on the pipe fitting to be processed, the pier nose mould is advanced, in pier nose mould running, promote the slip counterdie and make slip counterdie and the fixing pipe fitting section between the counterdie form annular projection, pipe fitting mouth of pipe place is also because squeezing action formation annular projection simultaneously.

Certainly, above-mentioned explanation is not to be limitation of the present invention, and the present invention also is not limited in above-mentioned giving an example, and the variation that those skilled in the art make in essential scope of the present invention, remodeling, interpolation or replacement also should belong to protection scope of the present invention.
