Abstract
The utility model relates to a cutting machine of a pressure container closed termination, which mainly comprises a positioning and compaction mechanism, a transmission mechanism, a cutting knife and a feed unit. The surroundings of a disk-shaped inner cutting knife and a disk-shaped outer cutting knife are provided with cutting blades. The utility model can carry out the clearance shearing to work pieces, change and regulate the thickness of a filler sheet and regulate the shearing clearance. The feed unit of the outer cutting knife is provided with a regulating mechanism to regulate the skew angle of the axial line of an inner cutting blade and the axial line of the outer cutting blade, and the working needs are ensured. The utility model changes the brute force squeeze of the existing cutting device into the clearance shearing and has the advantages of small stress after the work pieces are processed and small burr. The utility model can eliminate the phenomena of root face, dislocation and cracking and effectively enhance the processing quality of the work pieces and the durability of the cutting knife, and the annealing treatment is not needed.
Description
The utility model relates to a kind of end socket slotting machine of pressure vessel head slotting machine, especially cylinder for liquefied gas.
Existing steel cylinder seal head notching device is that workpiece is enclosed within on the garden plate-like mold that hardens, with the garden arc spots localization at workpiece flange place, no inner cutter.During work, become the outer cut at 65 ° of angles to be squeezed in workpiece along the diameter of work direction, make workpiece extruding place material production mobile strongly, internal stress increases, so the workpiece need through annealing in process, otherwise very easily crack.The outer cut that is fixed on the planker is advanced and retreat by cam control, produces rigidity with mold inevitably and contacts, the wearing and tearing aggravation.By the workpiece of this notching device processing, burr is big, and root face, misalignment are serious, influences the main weld quality of steel cylinder.
The purpose of this utility model is to overcome the weak point of existing steel cylinder seal head notching device, provide a kind of and make that end socket incision stress is little, burr is little, disappearing is coated with root face, misalignment and cracking phenomena, the pressure vessel head slotting machine of raising crudy and cutting knife durability.
Technical solutions of the utility model are: the pressure vessel head slotting machine is made up of location and hold-down mechanism, transmission mechanism, cutting knife and delivering gear major part.Be provided with the ellipsoid mold in the hold-down mechanism of location, it is reliable to guarantee that the location compresses.Be provided with plate-like inside and outside cutting knife in garden in cutting knife and the delivering gear, add man-hour material to be formed and shear.The axes intersect of inside and outside cutting knife becomes the angle less than 90 °, and outer cut links to each other with the delivering gear that has governor motion, can adjust the size at outer cut axis and inner cutter axes intersect angle by governor motion, to adapt to the needs of workpiece shearing.
Inside and outside cutting knife has peripheral cutting blade in its lower surface and upper surface respectively, and two cutting blades do not contact, and reduce wear.Garden plate-like cutting knife reconditioning is convenient, can use continuously.Inner cutter cutting blade one side is provided with elasticity limit material circle, to guarantee that shearing useless circle is in the tram.Outer cut cutting blade one side is provided with the adjustment pad, changes the thickness of adjusting pad, can regulate the gap between inside and outside cutting knife cutting blade, to adapt to the shearing requirement of different-thickness material.The outer cut delivering gear is a hydraulic drive mechanism, and the transmission balance can realize stepless speed regulation according to shearing needs.The governor motion that delivering gear has is screw rod, nut body or other governor motion, and is easy to adjust, reliable operation.Outer cut is located with the upper surface, is upwards held out against by screw by lateral pin.
The utility model is rational in infrastructure, and is easy to adjust, reliable operation, and to the otch processing of pressure vessel head, stress is little, and burr is little, no root face, misalignment and cracking phenomena, workpiece do not need annealing in process, cutting knife durability height, long service life.
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation.
Fig. 2 is delivering gear and outer cut clamping part schematic diagram.
Present embodiment is made up of location and hold-down mechanism, transmission mechanism, cutting knife and delivering gear major part.Workpiece 1 is located by ellipsoid mold 2, and compresses from the top.Mold 2, garden plate-like inner cutter 3, elasticity limit material circle 4 all is contained on the main shaft 5, rotates thereupon.Main shaft 5 links to each other with reducing gear 6.Each major part all is fixed on the base plate 7.Garden plate-like outer cut 8 links to each other with delivering gear 9, and delivering gear 9 is provided with screw rod, nut adjusting mechanism 10, adjusts this governor motion and drives delivering gear around support 11 rotations, can change the angle of intersection α of inside and outside cutting knife axis.According to the specific requirement of workpiece welding, generally get α=30 °～45 °.Delivering gear 9 is a hydraulic gear, and outer cut is arranged on the planker 12 that links to each other with oil cylinder 13.Under planker drives, by the following cutting blade realization of the last cutting blade of outer cut and inner cutter shearing to workpiece.Two cutting blades do not contact, and its gap is adjusted by the adjustment pad 14 that is contained in cutting blade one side on the outer cut.Outer cut does not change shear gap by end face 15 location of cutting blade one side behind the cutting knife sharpening.The clamping of outer cut is upwards held out against by screw 17 by lateral pin 16.
