Description
Technical field
The utility model relates to grooving apparatus, particularly a kind of grooving apparatus of steel tube head.
Background technology
Existing steel pipe grooving apparatus, steel tube head is slotted and added man-hour, steel tube head is inserted to excellent core, normally single cutter is slotted to steel tube head through a side of excellent core along single direction, during fluting, cutter acts on a side of steel tube head, can continue extruded rod core simultaneously, and therefore excellent core easily fractures.Also need rotating steel tube to reach different groove Working positions, working (machining) efficiency is lower, and the while may occur deviation and cause and scrap.
Utility model content
The purpose of this utility model is that a kind of steel pipe grooving apparatus will be provided, and can solve the problem of groove working (machining) efficiency and excellent core intensity.
According to an aspect of the present utility model, steel pipe grooving apparatus is provided, comprise support, the two ends of support are provided with driving cylinder, and support is provided with excellent core, is fixed with cutter on driving cylinder, and the both sides of excellent core are provided with the groove that corresponding cutter is passed.
Its beneficial effect is: because excellent core inserts in steel tube head, driving cylinder drives cutter separately from support two ends to excellent core simultaneously, each cutter completes feed motion and the withdrawing motion of the processing of steel tube head groove through corresponding groove, make the both sides of excellent core all be subject to the extruding force of steel tube head both sides, avoid excellent core to fracture, therefore can realize the enhancing of excellent core intensity.Because the driving cylinder of the every one end of support can be for a plurality of, each driving cylinder is worked simultaneously, and each cutter just can complete many places fluting, can also change the position of excellent core both sides groove, just can slot to the different parts of steel tube head, therefore can realize the raising of groove working (machining) efficiency.
In some embodiments, the two ends of support are separately installed with a driving cylinder, and two driving cylinders are along same linear drives, and excellent core is tubular, and the both sides of excellent core are respectively equipped with a groove, and groove is symmetrical along the axis of excellent core.Its beneficial effect is: because two driving cylinders are along same linear drives, groove is symmetrical along the axis of excellent core, and when two cutters are slotted to steel tube head simultaneously, steel tube head is stressed evenly, thereby it is also less that excellent core is subject to the offset loading force of steel tube head, therefore can realize higher excellent core intensity.
In some embodiments, cutter comprises knife rest and cutter hub, and knife rest is fixed on driving cylinder, and cutter hub is arranged on knife rest, and the both sides of excellent core are provided with the groove that corresponding cutter hub is passed.Its beneficial effect is: because each cutter hub can pass corresponding groove, feed motion and the withdrawing that therefore can realize driving cylinder driving knife rest and drive cutter hub to complete the processing of steel tube head groove through corresponding groove by knife rest move.
In some embodiments, between two driving cylinders, be provided with guide pillar, the two ends of every guide pillar are individually fixed in the two ends of support, and guide pillar is through two knife rests, and each knife rest can slide with respect to guide pillar.Its beneficial effect is: because two driving cylinders drive respectively two knife rests, on guide pillar, slide, guide pillar plays position-limiting action to two knife rests, can avoid because vibration causes cutter hub and groove, being shifted in groove process, therefore can realize and improve groove machining accuracy.
In some embodiments, one end of excellent core is provided with blanking cylinder.Its beneficial effect is: because the blanking after steel tube head fluting residues in excellent in-core, under the effect of blanking cylinder, therefore can realize the blanking of steel pipe fluting is cleared out in steel pipe.
In some embodiments, driving cylinder is hydraulic cylinder.Its beneficial effect is: because piston rod and the cutter of hydraulic cylinder are fixed, thereby therefore can realize piston rod, move back and forth feed motion and the withdrawing motion that realizes cutter under the hydraulic drive of hydraulic cylinder.
In some embodiments, driving cylinder is pneumatic cylinder.Its beneficial effect is: because piston rod and the cutter of pneumatic cylinder are fixed, thereby therefore can realize piston rod, move back and forth feed motion and the withdrawing motion that realizes cutter under the Pneumatic Transmission of pneumatic cylinder.
The utility model is simple in structure, easy to operate, has effectively avoided the phenomenon that fractures of excellent core in steel tube head groove process, and has improved groove working (machining) efficiency.
Accompanying drawing explanation
Fig. 1 is the schematic perspective view of the steel pipe grooving apparatus of a kind of embodiment of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 has schematically shown the steel pipe grooving apparatus according to a kind of embodiment of the present utility model.
As shown in Figure 1, this steel pipe grooving apparatus comprises support 1, and the two ends of support 1 are separately installed with a driving cylinder, this driving cylinder can be hydraulic cylinder or pneumatic cylinder, be preferably 2, two hydraulic cylinders 2 of hydraulic cylinder along same linear drives, and driving direction is vertical with the axis of excellent core 5.The centre of support 1 is provided with excellent core 5, and excellent core 5 is tubular, is preferably cylindric, and cylinder is outer for inserting steel tube head, can according to the size of pipe diameter, change the excellent core 5 of various outer diameter, to adapt to the chamfer putting steel tube processing request of different tube diameters.The both sides of rod core 5 are respectively equipped with a groove 6, and groove 6 is symmetrical along the axis of excellent core 5.On two hydraulic cylinders 2, be all fixed with cutter, cutter comprises knife rest 3 and cutter hub 4, and knife rest 3 is fixed on the piston rod of two hydraulic cylinders 2, and knife rest 3 is provided with cutter hub 4, and cutter hub 4 can pass corresponding groove 6.。Between two hydraulic cylinders 2, be provided with four guide pillars 8, the two ends of guide pillar 8 are individually fixed in the two ends of support 1, and guide pillar 8 is through knife rest 3, and knife rest 3 can slide with respect to guide pillar 8.One end of rod core 5 is provided with blanking cylinder 7 vertically, and the piston rod of blanking cylinder 7, in the cylinder of excellent core 5, can be released the blanking bits after fluting from the other end of excellent core 5.
