Abstract
The utility model relates to a machine for reducing the diameter of a pipe end, which comprises a base, a transmission mechanism, a pressing device, a cutter frame, a rotating head and a control part, wherein the pressing device is in a pneumatic type, and the transmission mechanism uses a combined mechanism of a motor, a belt pulley, a bevel gear, a worm wheel, a worm screw, a swing rod and a connecting rod. A cam which is coaxial with the worm wheel can control the cutter frame which is arranged on a sliding guide rail to make cutter feeding movement and cutter retracting movement, and a rolling cutter arranged on the cutter frame and the rotating head which is fixed to the upper end of a main shaft can commonly form reducing movement to a sealing head of a steel cylinder. Sealing heads which are reduced are oppositely inserted, and then, the sealing heads are welded. Thus, the original liner is saved, materials and labor are saved, and the cost is lowered. The phenomena, such as under cut, weld penetration, etc. generated in the welding process of the liner can be avoided, and the quality of the steel cylinder is improved. The utility model is particularly suitable for the automatic production line of the steel cylinder, and can carry out manual production of the single machine.
Description
The utility model relates to a kind of metal rolling processing unit (plant), especially for the necking machine of liquefied gas steel cylinder seal head processing.
Cylinder for liquefied gas is welded by end socket, and end socket carries out butt welding through drawing and after neat mouthful of processing.For guaranteeing the butt welding quality, be to add lining in the weld seam inboard in the past, this is consume material not only, increases man-hour, the rising that brings production cost, but also phenomenons such as undercut that the lining welding occurs, burn-through are often arranged, influenced the qualification rate of steel cylinder.
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of material-saving saving of labor is provided, reduces production costs, and can improve the necking machine of steel cylinder welding quality again.
The technical solution of the utility model is: necking machine comprises support, transmission mechanism, hold down gag, knife rest, swivel head and control section, and hold down gag mainly is made of cylinder and the supporting plate, the aligning pressure head that are attached thereto and the carrying roller that is installed on the frame surface.Transmission mechanism is a motor--belt pulley--bevel gear--worm screw, worm gear--cam, roller--combined mechanism of fork, connecting rod.The knife rest that links to each other with connecting rod is arranged on the line slideway, and swivel head is fixed on the upper end of vertical drive shaft, and knife rest is provided with the discoid hobboing cutter that becomes matched in clearance with axle, and its installation site is corresponding with the step of swivel head bottom.
On the above-mentioned knife rest adjusting screw(rod) is arranged, the periphery of described discoid hobboing cutter has tapering.
Adopt technique scheme, the utility model compact conformation, motion flexibility and reliability, match with pneumatic pusher roller-way, can realize the automated exchanged cutter to end socket, autofeed roll extrusion reducing makes the oral area of end socket form a regular step, with another not the end socket of reducing to inserting the back welding, do not need to add lining, thereby the material-saving saving of labor, production cost reduced, and can avoid phenomenons such as undercut that lining welding appears, burn-through, improve the welding quality of steel cylinder.The utility model is particularly useful for the cylinder for liquefied gas automatic production line.
Further specify the utility model below in conjunction with drawings and Examples.
Accompanying drawing is the utility model structural representation.
Cylinder 1 drives supporting plate 2 and 12 times general who has surrendered's end sockets of aligning pressure head are pressed on the carrying roller 3.Motor drives cams 6 by belt pulley, bevel gear 4, worm and gear 5 and rotates, the roller motion on the cam control fork 7, and drive the knife rest 9 that is arranged on the linear motion guide by connecting rod 8 and do feed, withdrawing motion.Hobboing cutter 10 peripheries that are located on the knife rest have tapering, and its position is corresponding with the step of swivel head 11 belows of being fixed in the vertical drive shaft upper end.Swivel head drives end socket and rotates hobboing cutter friction rotation during work.Adjusting screw(rod) is arranged, in order to tool setting and hand feed on the knife rest.Cam rotates a week, finishes the reducing of an end socket.
