Abstract
The invention provides a dimension correcting die for openings of large-aperture U-shaped tubes. A supporting rack structurally includes that a cushion plate is cushioned on the lower portion, which is arranged at a notch on a base, of a fixed end for a U-shaped tube, an arc-shaped sizing block is cushioned on two sides of the U-shaped tube, wedges are embedded on two sides of the arc-shaped cushion plate, and a port fixing baffle plate, a center fixing baffle plate, a flaring baffle plate and a contracting baffle plate are successively arranged at the upper end of the base from right to left. A hydraulic mechanism structurally includes that a hydraulic cylinder is mounted on the base at a retractable pressing end for the U-shaped tube, fixing racks are disposed on two sides of the hydraulic cylinder and are connected onto the base via bolts, and one end of a retractable head of the hydraulic cylinder is movably connected with a spherical press head. By the aid of the supporting rack and a hydraulic mechanism, correction and adjustment of the dimension of an opening of the large-aperture U-shaped tube can be realized. The dimension correcting die for openings of large-aperture U-shaped tubes is suitable for correcting the large-aperture U-shaped tubes when the U-shaped tubes are manufactured.
Description
Technical field
What the present invention proposed is the mould of a kind of heavy caliber U-shaped tube opening size school shape of mechanical manufacturing field application.
Background technology
At present, heavy caliber U-shaped pipe uses hydraulic press and conventional mould to realize that in perpendicular angle is shaped usually.Because the restriction of pipe self bounce-back and the restriction of die shape, the opening size of heavy caliber thick wall U-shaped pipe is difficult to guarantee.And compacting is managed into U-shaped and is realized the secondary forming to the pre-bending pipe fitting through heavy caliber thick wall U-shaped tube opening size school shape mould step by step, is the needs that can guarantee the opening size of U-shaped pipe fitting.
Summary of the invention
The technical problem that the present invention will solve provides a kind of heavy caliber U-shaped tube opening size school shape mould, can control effectively to guarantee heavy caliber thick wall U-shaped pipe port size.
The scheme that technical solution problem of the present invention is adopted is:
Supporting frame structure: U-shaped pipe stiff end; The bottom of the indentation, there on base is lined with backing plate; Both sides are lined with the arc parallels, are embedded with drift in arc backing plate both sides, are provided with port fixed dam, center fixation baffle plate, enlarging baffle plate and reducing baffle plate from right to left successively in the base upper end.
The hydraulic mechanism structure: the flexible end of pressing of U-shaped pipe, at base hydraulic cylinder is installed, the hydraulic cylinder both sides are provided with fixed mount, are connected on the base through bolt, are connected with the sphere pressure head at the flexible first end of hydraulic cylinder.
Good effect, the present invention is through the setting of supporting frame and hydraulic mechanism, the school shape and the adjustment that can solve heavy caliber U-shaped tube opening size.Suit to use the manufacturing lieutenant colonel shape of heavy caliber U-shaped metal tube.
Description of drawings
Fig. 1 is a die structure dwg of the present invention
Fig. 2 is a mould user mode sketch map of the present invention
Among the figure, 01. supporting frame, 02. hydraulic mechanism, 1. base, 2. hydraulic cylinder, 3. fixed mount, 4. bolt, 5. sphere pressure head, 6. drift, 7. backing plate, 8. arc parallels, 9. port fixed dam, 10. center fixation baffle plate, 11. enlarging baffle plates, 12. reducing baffle plates.
The specific embodiment
Shown in figure, mould of the present invention is constituted by supporting frame 01 and hydraulic mechanism 02.
Supporting frame 01 structure: U-shaped pipe stiff end; The bottom of the indentation, there on base 1 is lined with backing plate 7; Both sides are lined with arc parallels 8; Be embedded with drift 6 in arc backing plate both sides, be provided with port fixed dam 9, center fixation baffle plate 10, enlarging baffle plate 11 and reducing baffle plate 12 from right to left successively in the base upper end.
Use of the present invention:
1, selects reducing baffle plate or enlarging baffle plate position, use fixed mount 3 that hydraulic cylinder is fixed on the base, and hydraulic cylinder and reducing baffle plate or enlarging baffle plate are leaned on sternly as school shape.
2, the sphere pressure head is connected with cylinder ends, as the output of pressure.
3, the U-shaped pipe is hung onto on the backing plate on the base, the height of adjustment backing plate makes the center of pipe overlap with the center of sphere pressure head, and the cambered surface pressure surface complete and pipe fitting of sphere pressure head is fitted.
4, on port fixed dam and center fixation baffle plate, utilize arc parallels and drift that the U-shaped pipe is locked.
5, configure preparatory school size, through twice precompressed, calculate rebound amount after, school shape U-shaped tube opening size several times.
Said U-shaped tube opening size is the distance between the U-shaped tube head two ends.School shape promptly is through the fixing end of U-shaped pipe of U-shaped pipe stiff end, presses the other end of U-shaped pipe with the hydraulic pressure end, and the distance between two pipe ends of adjustment U-shaped pipe makes it to meet the needs that opening size is set.
Said breach is meant the placement fixed position, space of U-shaped pipe stiff end.
