Abstract
The invention relates to a mould for bending tube stock, in particular to a rectangular thin walled tube stock tracking deformation bending mould. The mould comprises a main bending mould, a follow-up slide block, a clamping jaw and a tracking deformation core mark, wherein the tracking deformation core mark comprises a connecting rod, link plates, pins and core mark bodies, a plurality of link plates are connected together through pins and are arranged in a plurality of the core mark bodies, one end of the connected link plates is connected with the connecting rod through pins, the connecting rod is connected with the mandril oil cylinder of the tube bending machine, the main bending mould is arranged on the main shaft of the tube bending machine through splines, the follow-up slide block and the clamping jaw are arranged above the rectangular thin walled tube stock, and the follow-up slide block and the clamping jaw can be driven by the oil cylinder to press or release the section. The above moulds are combined to be connected with the tube bending machine so as to realize the bending and forming of the rectangular thin walled tube stock. The mould of the invention has the advantage that the tube-bending work precision and work efficiency are high and the cost can be reduce by more than 50%, compared with the traditional tube-bending method by filling sand and heating.
Description
Technical field
The present invention relates to the mould that a kind of bending pipes is used, specifically a kind of rectangular thin walled tube stock tracking deformation bending mould.
Background technology
The workpiece that utilizes rectangle thin wall pipe material to bend is widely used in industries such as shipbuilding, rolling stock manufacturing, oil, chemical industry and building.At present for the following several modes of the many employings of the making of pipe fitting:
1. for the workpiece that bending radius is big, tube wall is thicker, generally on profile bender, process;
2. the workpiece less for bending radius, that tube wall is thicker is generally processed on bending machine;
3. the workpiece less for bending radius, that tube wall is thin, the general mode of filling out sand and heating that adopts is processed, and this kind processes efficient is low, processing cost is high.Also manyly when less demanding for workpiece accuracy complete on bending machine, phenomenon as shown in Figure 1 very easily appears in the cross sectional shape of its workpiece elbow, and the bend pipe precision is relatively poor.
Summary of the invention
The purpose of this invention is to provide a kind of rectangular thin walled tube stock tracking deformation bending mould that can bend rectangle thin wall pipe material accurately.It can cooperate the common apparatus of forging industry----bending machine, can be with the brake forming of rectangular thin-wall metal pipe material high accuracy.
The present invention is by the principal curvature mould, with movable slider, clamping claw and tracking distortion core print are formed, follow the tracks of the distortion core print by connecting rod, carrier bar, pin, the core print body is formed, a plurality of carrier bars are installed in a plurality of core print bodies and by pin and connect, one of the carrier bar that couples together is connected with connecting rod by pin, connecting rod is connected with bending machine plug oil cylinder, the principal curvature mould is installed on the bending machine main shaft by key, with movable slider, clamping claw is above rectangle thin wall pipe material, slide with rectangle thin wall pipe material with movable slider, with movable slider, clamping claw clamps or loosens the driving of section bar by oil cylinder.
Two forks of above-mentioned carrier bar, first fork, each has stuck circular hole.
Above-mentioned core print external body is a shape in the tubing, in the rectangular through-hole that can penetrate carrier bar is arranged, there is half slot at two ends.
One on above-mentioned connecting rod has two forks, twoly sticks porosely, and one has internal thread.
During work, stretch out plug oil cylinder piston bar in the position of loosening, make and follow the tracks of the deformed region that the distortion core print is in shape bending with movable slider and clamping claw; Make section bar pass tracking distortion core print during material loading and be placed on correct operating position, make then with movable slider and clamping claw action and compress section bar, can carry out crooked instruction this moment, the principal curvature mould is rotated under the drive of bending machine main shaft, and with movable slider under the driving of oil cylinder with the horizontal slip of rate of bending coupling, clamping claw mates with rate of bending and moves; After the bending pipes moulding, the backhaul of bending machine plug oil cylinder makes and follows the tracks of distortion core print disengaging deformed area, makes at last with movable slider and clamping claw backhaul and can take off workpiece.
The present invention has following advantage compared with prior art:
Bend pipe operating accuracy height, high efficiency, and more traditional husky heating bend method expense of filling out reduces more than 50%.
