According to the forming die, by arranging the bending die comprising the arc section and the straight section and arranging the pressing die and the clamping die both matched with the bending die for clamping the pipes, the machining errors of the U-shaped bent pipes are reduced, the machining precision is guaranteed, and the machining efficiency is improved.
Description
Technical field:
The present invention relates to condenser bend pipe technical field of processing equipment, particularly to a kind of condenser U-bend mould.
Background technology:
In prior art, U-tube for minor radius produces, at present basic adopting the curved mode of mould, namely pipe fitting is pressed on bending die by clamping die, and with bending die synchronous rotary, pipe fitting is driven to move in a circle around bending die center, until required angle, before entering clamping die, pipe fitting is in pressing mold, pipe fitting is also applied certain radial pressure by pressing mold, and does axial straight line boosting towards bending direction. Owing to pipe fitting has flexing resistance, therefore in actual production, pipe fitting flexibility is 175 �� ~ 178 ��, when using this mode of production for the U-tube that required precision is high, it is necessary to workman bends correction further by hand, and machining accuracy is low, and production efficiency is low.
Summary of the invention:
The invention provides a kind of condenser U-bend mould, solve flexibility in prior art and be difficult to reach 180 ��, machining accuracy is low, the problem that production efficiency is low.
The technology solution of the present invention is as follows: a kind of condenser U-bend mould, it includes the pressing mold arranged on the table, clamping die and bending die, described pressing mold, clamping die and bending die are respectively equipped with semi-circular recesses, described bending die includes arc section and flat segments, the dual-side symmetry of described flat segments and its extended line become 2 �� ~ 5 �� angles, the side extended line of the flat segments that the axial line of the semi-circular recesses in described flat segments is adjacent respectively is parallel, semi-circular recesses on described arc section is smoothly connected with the semi-circular recesses in flat segments, described pressing mold, clamping die coordinates with bending die to clamp pipe fitting.
As preferably, described bending die is rotationally connected by rotating shaft and workbench.
As preferably, described pressing mold is arranged at bending die side by pushing mechanism. Pipe fitting is applied certain radial pressure by pressing mold.
As preferably, described clamping die side forms fixture block, described clamping die is connected with connecting portion by fixture block, described connecting portion is arranged on flat segments side by cranked mechanism, described clamping die opposite side side side adjacent with flat segments side is parallel to each other, and the rotational axis line of clamping die overlaps with rotating shaft core line. Pipe fitting is pressed on bending die by clamping die, and with bending die synchronous rotary, drive pipe fitting move in a circle around bending die center.
As preferably, described cranked mechanism includes the vertical push rod being articulated and connected with connecting portion, and described vertical push rod one end and connecting portion are articulated and connected, and the other end is hingedly connected with promotion cylinder.
The beneficial effects of the present invention is: by arranging the bending die including arc section and flat segments, and coordinate the pressing mold to clamp pipe fitting and clamping die with bending die, reduce the mismachining tolerance of U-bend, it is ensured that machining accuracy, improve working (machining) efficiency.
