Description
Technical field
The utility model relates to the curved mould of a kind of rectangular tube.
Background technology
For the very large hollow square tube first order buckling moulding process of crooked amplitude, moulding is very difficult, sometimes the hollow square tube that workpiece is 40 * 70 * 3mm, inside radius of the bend reaches 1465mm, real arcs reach 741mm, crooked amplitude is very large, square tube hollow and wall are thin, when crooked, be easily out of shape, design difficulty is very big, add that Product Precision is high, when crooked, resilience is difficult to calculate accurately, will be through repeatedly adjusting and just likely meet drawing requirement, and bending apparatus is hydraulic press, there is no ejecting mechanism, workpiece discharging brings very large trouble like this, with rubber, eject strength inadequate, therefore to consider special discharge way.
Utility model content
The purpose of this utility model is to provide a kind of low cost of manufacture, easy to use, the curved mould of rectangular tube that can guarantee compact dimensions.
The technical solution of the utility model is: the curved mould of a kind of rectangular tube, it comprises upper die and lower die, described counterdie comprises block I, baffle plate, die shoe and die, the upper surface middle part of die shoe is provided with two baffle plates, distance between baffle plate matches with the width on the press-bending limit of rectangular tube to be bent, and the die that rectangular tube design radian to be bent matches is placed between two baffle plates, and in order to prevent the play of die horizontal direction, the two ends of die are respectively equipped with block I; Described patrix comprises block II, limited block, upper bolster, punch, the position that the lower surface of upper bolster and die match is provided with the punch matching with rectangular tube design radian to be bent, the both side ends of punch is provided with respectively block II, the position matching at upper bolster and two baffle plates is provided with limited block, after die and punch matched moulds, the distance between limited block and baffle plate with wait that the height of rectangular tube to be bent matches.
In order to prevent that thin-walled rectangular tube from exerting pressure, time distortion is larger, in described rectangular tube, is filled with sand, and the rectangular tube two ends of filling sand are provided with technique cover plate.
In order to save processing, described die shoe is together with being bolted between baffle plate, the both sides of baffle plate are respectively equipped with two or more than two gripper shoe, and gripper shoe is fixed and welded together with corresponding baffle plate, together with two end supports plate is fixed by a pin to die shoe.
Useful technique effect of the present utility model is, in die both sides, be provided with baffle plate, thereby located the front-back of rectangular steel pipe, the correspondence setting of die and punch, guaranteed the bending radius after rectangular steel pipe processing, the distance between limited block and baffle plate with wait that the height of rectangular tube to be bent matches, guaranteed the arc length of rectangular steel pipe after processing, particularly in rectangular tube, be filled with sand, prevent from being out of shape when thin-walled rectangular tube from exerting pressure larger.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
With reference to accompanying drawing, the curved mould of a kind of rectangular tube, it comprises patrix, counterdie, described counterdie comprises block I 7, baffle plate 2, die shoe 5 and die 3, the upper surface middle part of die shoe 5 is provided with two baffle plates 2, between die shoe 5 and baffle plate 2, by bolt I 4, be fixed together, distance between baffle plate 2 matches with the width on the press-bending limit of rectangular tube to be bent 13, and the die 3 that rectangular tube 13 design radians to be bent match is placed between two baffle plates 2, in order to prevent the play of die 3 horizontal directions, the two ends of die 3 are respectively equipped with block I 7, block I 7 is fixed on die shoe 5 by bolt V 8, the outside of baffle plate 2 is provided with gripper shoe 1, gripper shoe 1 is fixed and welded together with baffle plate 2, gripper shoe 1 and the die shoe 5 at two ends are fixed together by pin 6, described patrix comprises block II 15, limited block 17, upper bolster 10, punch 12, the position that the lower surface of upper bolster 10 and die 3 match is provided with the punch 12 matching with rectangular tube 13 design radians to be bent, punch 12 is fixed together by bolt II 11 and upper bolster 10, the both side ends of punch 12 is provided with respectively block II 15, block II 15 is fixed on punch 12 by bolt III 9, the position matching at upper bolster 10 and two baffle plates 2 is provided with limited block 17, limited block 17 is fixed on upper bolster 10 by bolt IV 16, after die 3 and punch 12 matched moulds, distance between limited block 17 and baffle plate 2 with wait that the height of rectangular tube to be bent 13 matches, in order to prevent that thin-walled rectangular tube from exerting pressure, time distortion is larger, in described rectangular tube 13, be filled with sand, rectangular tube 13 two ends of filling sand are provided with technique cover plate 14.
During operation, by regulating the height of patrix limited block 17 to guarantee the gap of punch 12 and die 3 after matched moulds.When patrix and counterdie matched moulds, because front and back plane is shaped by lower die baffle plate 2, square tube is filled full sand, and the power of patrix is uniformly distributed in lower plane in square tube, and square tube profile is with the profile brake forming of punch 12, die 3.
