Abstract
The invention discloses a U heat exchange pipe bending machine, which comprises a rack, a bending mould and a bend pipe fixed mould wheel, wherein the bending mould is arranged at an eccentric position of a rotary disc; an axial end on one side of the rotary disc is connected with a driving device, and the other end of the rotary disc is arranged on a supporting frame; the bend pipe fixed mould wheel is independently arranged on the supporting frame and corresponds to the bending mould on the same central line; and a pipe clamping positioning sleeve is arranged on one side of the corresponding supporting frame between the bend pipe fixed mould wheel and the bending mould. Thus, the forming quality is guaranteed through quick bend pipe forming of the pipe bending machine. Meanwhile, U heat exchange pipes of various specification requirements can also be met by replacing the mould wheels of different specifications, so that the application range is expanded.
Description
Technical field
The present invention relates to a kind of bending machine, is a kind of U type heat exchanger tube bending machine specifically, has effectively improved bending quality and efficient.
Background technology
Heat exchanger is to utilize tube bank to be connected with the through hole of tube sheet, adopts U type bend pipe to be connected to form sealing U-shaped loop at the tube bank opposite side, guarantees that turning back of medium is mobile.Being used to bend U type metal heat exchanger tube at present is to accomplish with manually-operated.Mainly be to utilize on the support body, two rollers be set according to the requirement that bends U type metal tube, and between two rollers with the locating detent in its formation gap.When bending, insert between two rollers metal tube and locating detent one side, curving metal tube by manual work becomes U type pipe.Because the artificial U type pipe that bends needs the regular hour, like this, in curving process, cause the warpage of U type pipe, not on same plane because of unbalance stress.In addition, bend the demoulding after, make U type pipe after the moulding because the effect of internal stress produces distortion, can't guarantee installation dimension, need handle.Therefore, manually-operated must bend efficient, yield rate is low.
Summary of the invention
In view of above-mentioned present situation, the purpose of this invention is to provide a kind of U type heat exchanger tube bending machine, improve the accuracy of manufacture of the U type heat exchanger tube that bends, satisfy installation requirement.Simultaneously, also can adapt to the U type pipe of many specification requirements, improve range of application through changing the mould shape wheel of different size.
For realizing above-mentioned purpose, technical scheme of the present invention is: a kind of U type heat exchanger tube bending machine, comprise frame, and the bending mould that is installed on it; Wherein, Described bending mould is to be fixedly mounted on the eccentric position of a rotating disc; Rotating shaft one end on the rotating disc is connected with drive unit, and other end cantilevered axle is installed on the bracing frame, and the bend pipe pattern wheel of a free swivel is installed at said cantilever axle head; This bend pipe pattern wheel and bending mould are on same center line, and bend pipe pattern wheel is provided with card pipe positioning sleeve with the pairing bracing frame of tangential direction that bending mould intersects.During bend pipe, metal tube is managed by card and is passed bend pipe pattern wheel and bending mould after positioning sleeve is introduced, and moves bending mould around the synchronous rotation of bend pipe pattern wheel rapid shaping U type pipe through the dribbling of drive unit driven in rotation.
In the present invention, related bending mould comprises connecting plate; Regulate sliding sleeve with the pressure pipe that is installed on the connecting plate, this presses pipe to regulate in the sliding sleeve is the square hole slideway, and its bottom has a screw and is communicated with; Wherein the screw rod of in the square hole slideway, introducing is being installed on the screw; Also comprise the inner nut cover that is installed in the square hole slideway of pressing pipe to regulate sliding sleeve, this inner nut set upper side is provided with presses the pipe wheel, and described inner nut cover is connected cooperation with screw rod.When the both forward and reverse directions rotary screw, control inner nut cover and on the up-down of pressure pipe wheel, adjusting suitable thrust, and the requirement of satisfying different tube diameters.
In the present invention, related card pipe positioning sleeve comprises a horizontal sleeve pipe and inserted link connected vertically with it, cooperates with slot on being installed in bracing frame through inserted link, and this slot is provided with set screw.Therefore, regulate the upper and lower displacement of locator card pipe positioning sleeve through set screw.
The good effect that the present invention has is: higher because of having adopted the special-purpose U type that bends metal pipe bender than original manually-operated bend pipe efficient, and, also solved the warpage that unbalance stress in the bend pipe process causes U type pipe, not in conplane problem.In addition, bend the demoulding after, make U type pipe after the moulding eliminate the distortion of internal stress, guaranteed installation dimension and quality.
