Description
Technical field
The utility model relates to a kind of pipe enlarging device, particularly a kind of manual thin-wall metal pipe mouth expander.
Background technology
As everyone knows, on the machinery equipment of industries such as refrigeration, power, processing, many interconnective thin-wall metal pipes are arranged all, the pipe two ends generally realize that in the sleeve mode simple assembling connects by enlarging, for this reason specialized designs be exclusively used in the enlarging device of thin-wall metal pipe enlarging, and existing enlarging device exists following weak point: the one, during the pipe enlarging, there is not pressure regulating mechanism, and can only process horn mouth by rule of thumb, not of uniform size, the became uneven of horn mouth, the crudy instability; The 2nd, operation inconvenience during enlarging, handle can only same direction rotate, and required torsion is bigger.
Summary of the invention
For overcoming the above-mentioned disadvantage that existing enlarging device exists, problem to be solved in the utility model provide a kind of simple and reasonable, volume is little, in light weight, pressure automatic control, the eccentric mouth expander of ratchet-type easy to operate, that exert oneself little.The technical scheme that its technical problem that solves the utility model adopts comprises handle, connector, press rods, pressure nut, bearing support, the pipe mould bases, trip bolt, described press rods is provided with compression spring, its lower end is fixed with guide pillar, guide pillar cooperates with linear bearing on being arranged on bearing support, guide pillar is provided with disalignment and rotating conical indenter, the vertex of a cone of conical indenter is coaxial with the guide pillar axle center, the press rods of stretching out pressure nut is fixed on the connector, be provided with pressure transfer device between connector and the pressure nut, be provided with ratchet device between handle and the connector.
Described pressure transfer device comprises pilot pin, top spring, and the pilot pin lower end is arranged on the following installing hole of pressure nut, and its upper end is arranged on the last installing hole of connector, and the top spring is arranged between installing hole and the pilot pin.
Described ratchet device comprises boss, ratchet, arc ratchet, annular dialing spring, the toggle of connector, be fixed on that ratchet is arranged on the boss of connector on the handle, be arranged on a side of boss with the arc ratchet of ratchet coupling, be fixed with finger on the toggle, finger is arranged on the opposite side of boss, the annular dialing spring is fixed on the arc ratchet and is enclosed within on the finger, and toggle is arranged on the end face of boss by dog screw.
For the resistance of reducing friction, the press rods of the upper and lower end face of described compression spring is provided with plane bearing.
For the ease of clamping tube, described trip bolt is provided with boosting-rod.
After adopting said structure, in pipe enlarging process, when the enlarging pressure of conical indenter pressurizes greater than the compression elasticity handle continuation of compression spring, pressure nut continues to screw in bearing support downwards, compression spring shrinks, press rods keeps original height, produces between connector and the pressure nut and separates, and makes the operator can grasp pipe enlarging quality well; Be provided with, can rotate freely because conical indenter is eccentric, so conical indenter and pipe contact-making surface are little, required moment of torsion is also just little, and enlarging is laborsaving; Since between connector and handle, be provided with ratchet device, so it is handle is free to advance or retreat in process, easy to operate; Have advantages such as simple and reasonable, pipe enlarging steady quality, rapid operation.
