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, the two arc-shaped cushion plates are equipped, and the side of each arc-shaped sizing block toward the port fixing baffle plate (9) are embedded with the wedges (6), 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 dimension correcting shape of mechanical manufacturing field application.
Background technology
At present, heavy caliber U-shaped pipe is used hydraulic press and conventional mould in perpendicular, to realize angle shaping conventionally.Due to 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 suppress step by step pipe, becoming U-shaped and realize the secondary forming to pre-elbow member by heavy caliber thick wall U-shaped tube opening dimension correcting shape mould, is the needs that can guarantee the opening size of U-shaped pipe fitting.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of heavy caliber U-shaped tube opening dimension correcting shape mould, to guarantee that heavy caliber thick wall U-shaped pipe port size can control effectively.
The scheme that technical solution problem of the present invention adopts is:
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, arc parallels has two, at each piece arc parallels, towards that side of port fixed dam (9), be embedded with drift (6), in base upper end, be provided with successively from right to left port fixed dam 9, center fixed dam 10, enlarging baffle plate 11 and reducing baffle plate 12.
Hydraulic mechanism structure: the U-shaped pipe pressure side of stretching, at floor installation, there is hydraulic cylinder, hydraulic cylinder both sides are provided with fixed mount, are bolted on base, at the first end of hydraulic cylinder extension, are connected with sphere pressure head.
Good effect, the present invention, by the setting of supporting frame and hydraulic mechanism, can solve school shape and the adjustment of heavy caliber U-shaped tube opening size.The suitable manufacture lieutenant colonel shape at heavy caliber U-shaped metal tube is used.
Accompanying drawing explanation

Fig. 2 is that mould of the present invention is used view
In 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 fixed dam, 11. enlarging baffle plates, 12. reducing baffle plates.
The specific embodiment
According to the 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, arc parallels has two, at each piece arc parallels, towards that side of port fixed dam (9), be embedded with drift (6), in base upper end, be provided with successively from right to left port fixed dam 9, center fixed dam 10, enlarging baffle plate 11 and reducing baffle plate 12.
Use of the present invention:
1, select reducing baffle plate or enlarging baffle plate as the position of school shape, use fixed mount 3 that hydraulic cylinder is fixed on base, and make hydraulic cylinder and reducing baffle plate or enlarging baffle plate by tight.
2, sphere pressure head is connected with cylinder ends, as the output of pressure.
3, U-shaped pipe is hung onto on the backing plate on base, adjust the height ，Shi Guan center of backing plate and the center superposition 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 fixed dam, utilize arc parallels and drift that U-shaped pipe is locked.
5, set pre-school size, by twice precompressed, calculate after rebound amount, several times school shape U-shaped tube opening size.
Described U-shaped tube opening size is the distance between U-shaped tube head two ends.School shape is by the fixing one end of U-shaped pipe of U-shaped pipe stiff end, by the other end of the moving U-shaped pipe of hydraulic pressure side pressure, the distance between two pipe ends of adjustment U-shaped pipe, makes it to meet the needs that opening size is set.
Described breach refers to the placement fixed position, space of U-shaped pipe stiff end.
