Description

A kind of pipe fitting forming machine for grooves

Technical field

The utility model relates to a kind of pipe fitting forming machine for grooves.

Background technique

Groove pipe fitting interconnection technique is also referred to as clamp connection technology, it has also become the first-elected skill that current liquid, gas pipeline connect Art.The application of groove pipe fitting interconnection technique makes complicated pipeline connection process become simple, quick and easy.Pipeline groove is pipe The critical process of road connection, also determines the important link of channel member quality of connection, and the width and depth dimensions of groove have to comply with It is required that.In slot rolling, smooth, impulse- free robustness is answered in nozzle end, and port should shut out in this way the groove and pipe come perpendicular to tube axis Subcenter axis could be vertical, while to guarantee that groove to the length of pipe end wants impartial.

The ditch Slot shaping of existing pipe fitting uses two kinds of forms, casting and forming and hot-roll forming mostly.Casting and forming is applicable in In the ditch Slot shaping of pipe fitting, for example, pipeline valve, threeway or four-way connection etc., hot-roll forming is suitable for the biggish pipe of length Road end, but its shortcoming is that, heating process is easy to damage the internal organizational structure of tube body and the appearance of tube body, be easy to cause The defects of tube body poor corrosion resistance.In addition, cold-rolling process is also suitable part pipe ends, but mostly uses punching press greatly or be squeezed into Type, the most existing defects of Forming Quality, needs the machining in later period to continue to supplement, thus production cost increases significantly, now There are no a kind of good and at low cost groove cold rolling molding equipments of Forming Quality.

Summary of the invention

The technical problem to be solved by the present invention is to provide one kind pipe end to be formed groove and molding matter automatically Measured pipe fitting forming machine for grooves.

In order to solve the above technical problems, provided pipe fitting forming machine for grooves includes rack, it is structurally characterized in that: the machine The lower part of frame is equipped with by the lower part shaping axle of power device driving rotation, and the end of lower part shaping axle is connected with molding lower die, at Type lower die is equipped with the groove of annular, is equipped in the rack and drives the lower lock block slid up and down by lower hydraulic driver, pushes The lower end of block be connected with the shaping upper that is correspondingly arranged of molding lower die, shaping upper have can be freely rotated and with the groove Corresponding lower compression roller above and below position, be connected in the rack can support pipe fitting to be processed support device.

The molding lower die includes support sleeve axis, and support sleeve axis has spaced two sections of supporting sections, two sections of supporting sections Between be less than the diminution section of supporting section for diameter, the space reduced between the outer surface of section and two sections of supporting sections forms the ditch Slot.

The supporting section and the outer surface for reducing section are equipped with driving burr.

The support device includes the support base of connection on the rack, is connected with height-adjustable support frame on support base, The support roller station of energy support pipe fitting to be processed is connected on support frame.

It is connected with the screw rod on support base on support frame as described above, is bolted with to cooperate with support base on the screw rod and incite somebody to action The locking nut of screw rod height locking.

The lower lock block is slidably connected on the rack by guide rail, and the lower hydraulic driver is electric pushrod, lower lock block It is connected by power with the power drive bar of electric pushrod.

The power device is connection servo motor on the rack, and the power of the lower part shaping axle and servo motor is defeated Shaft is connected by power, and the servo motor and electric pushrod are all electrically connected with PLC controller.

After adopting the above structure, pipe fitting to be processed is placed in support device and is mounted in the end sleeve of pipe fitting to be processed It forms in lower die, drives lower lock block to glide by lower hydraulic driver, be pressed against molding lower die outside the end of pipe fitting to be processed On surface, start power device, under the rotate driving of molding lower die, and gradually increases the pressure of lower hydraulic driver, make Molding lower die gradually moves down, and under the extruding of molding lower die and shaping upper, the end of pipe fitting to be processed is made to form groove.Using This structure carries out extrusion forming, and Forming Quality is good, and the machine structure is simple, labour production cost is greatly saved, also greatly Labor efficiency is improved greatly.Using the structure design of driving burr, pipe fitting to be processed can be made to produce during extrusion forming Raw more smoothly rotation, to guarantee the Forming Quality of groove.

In conclusion the utility model can be with the automatic moulding of the groove of pipe fitting end, the good, labor with groove Forming Quality Efficiency of movement is high, saves the advantages of production cost.
