Abstract
The utility model provides an elbow die, comprising bases, a lifting device and a main rotating wheel, wherein the bases include a first base and a second base, the first base is fixed on the ground through a screw, the upper part of the first base is fixedly connected with the lifting device, the main rotating wheel is fixedly connected to one side of the lower end of the lifting device, and a cross bar is arranged at the horizontal position of the top end of the lifting device, which is in the same direction with the main rotating wheel. The elbow die has the beneficial effects that the main rotating wheel and an auxiliary rotating wheel can be adjusted so as to press a straight pipe into an elbow, no welding operation is needed, the workload is small, the quality of the elbow is high, the distance between the main rotating wheel and an auxiliary rotating wheel can be adjusted so as to meet different bending requirements, the whole process is simple and convenient to operate. After an elbow is fixed and adjusted to a proper position, elbows with any sizes and curves can be realized through controlling the distance between the rotating wheels; moreover, the automatic operation can greatly save labor.
Description
Technical field
The utility model belongs to mould applications, especially relates to a kind of bend pipe mould.
Background technology
Bend pipe is to adopt complete bending mould to carry out bending, no matter is any machinery equipment, and major part is all used bend pipe, mainly, in order to oil transportation, gas transmission, transfusion etc., on aircraft and engine thereof, more occupies considerable status.
The deformation extent of tubing, depend on that size, R/D and the t/D value of relative bending radius R/D and relative thickness t/D numerical value is less, means that deformation extent is larger.For guaranteeing the pipe fitting forming quality, must control deformation extent in tolerance band, the tube bending forming limit not only depends on mechanical property and the bending method of material, but also considers the instructions for use of pipe fitting.The forming limit of pipe fitting should comprise following content: in stretcher strain district, (1) neutral line outside, the elongation strain of maximum is no more than the material plasticity permissible value and produces and break; (2), in neutral line inboard compression deformed area, be subjected to that the thin-wall construction part of circumferential compressive force effect is unlikely surpasses unstability and wrinkling; (3), if when pipe fitting has requiring of ovality, control its section and produce distortion; (4) if when pipe fitting has the requirement of strength of the internal pressure of bearing, control the forming limit of its wall thickness reduction.
In carrying out bend pipe manufacturing process, the radian of bend pipe is controlled very important, and excessive circular arc not only makes the frock heaviness, and is subjected to the restriction of bending machine lathe size; Arbitrary curve, composite bent design model are very unreasonable, have greatly hindered mechanization, automated production, make the operator be difficult to break away from heavy manual labor.
The utility model content
The purpose of this utility model be to provide a kind of simple in structure, easy to operate, production efficiency is high and hold manageable bend pipe mould.
The technical solution of the utility model is: a kind of bend pipe mould, comprise base, lowering or hoisting gear and main runner, and described base comprises the first base and the second base; Described the first base fixes on the ground by screw rod, and described the first base top is fixedly connected with lowering or hoisting gear; One side of described lowering or hoisting gear lower end is fixedly connected with main runner, is provided with cross bar on the top of described lowering or hoisting gear and the equidirectional horizontal level of main runner; One end of described cross bar is fixedly connected with the top of main runner, is provided with fixture on the other end of described cross bar; The center of described fixture is provided with and connects upper and lower through hole, and a side of described fixture is provided with clamping screw; Described the second base fixes on the ground by screw rod, on described the second base central upper portion horizontal level, laterally is provided with the sliding rail that connects both sides; On described sliding rail, be provided with box type column; The bottom of described box type column is provided with the track be complementary with sliding rail; One side of described box type column is provided with two runners arranged vertically; The outward flange of described runner and main runner is equipped with circumferential groove.
Advantage and the good effect that the utlity model has are: the utility model can come directly straight tube to be pressed into to bend pipe with time runner by regulating main runner, the welding operation, workload is less and bending quality is higher, camber for bend pipe also can reach the different cambers that require by the distance of regulating between main runner and inferior runner, whole process operation is simple and convenient, after completing fixed bending tube and bend pipe being adjusted to suitable position, by controlling the distance between runner, just can realize the bend pipe of arbitrary dimension and curve, the operation of automation simultaneously, also saved a large amount of labours.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure:
1, the first base 2, screw rod 3, lowering or hoisting gear
4, cross bar 5, fixture 6, through hole
7, clamping screw 8, main runner 9, inferior runner
10, box type column 11, sliding rail 12, the second base
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
As shown in Figure 1, a kind of bend pipe mould of the utility model, comprise base, lowering or hoisting gear 3 and main runner 8, and described base comprises the first base 1 and the second base 12; Described the first base 1 fixes on the ground by screw rod 2, and described the first base 1 top is fixedly connected with lowering or hoisting gear 3; One side of described lowering or hoisting gear 3 lower ends is fixedly connected with main runner 8, is provided with cross bar 4 on the top of described lowering or hoisting gear 3 and the equidirectional horizontal level of main runner 8; One end of described cross bar 4 is fixedly connected with the top of main runner 8, on the other end of described cross bar 4, is provided with fixture 5; The center of described fixture 5 is provided with and connects upper and lower through hole 6, and a side of described fixture 5 is provided with clamping screw 7; Described the second base 12 fixes on the ground by screw rod 2, on described the second base 12 central upper portion horizontal levels, laterally is provided with the sliding rail 11 that connects both sides; On described sliding rail 11, be provided with box type column 10; The bottom of described box type column 10 is provided with the track be complementary with sliding rail 11; One side of described box type column 10 is provided with two runners 9 arranged vertically, and described time runner 9 is equipped with circumferential groove with the outward flange of main runner 8.
The course of work of this example: the first base 1 and the second base 12 are fixed on ground by screw rod 2, during operation, insert straight tube in fixture 5 and keep plumbness, make simultaneously straight tube just in time be arranged in the outer peripheral groove of main runner 8, then moving belt has the box type column 10 of track, make the groove on two runner 9 outward flanges arranged vertically, just in time block straight tube, following main runner 8 makes straight tube bending become bend pipe under the pressing down of hydraulic stem, time runner 9 can be in the process that straight tube buckles and rotate under pressing down, can avoid like this friction, further improve bending quality.
