Abstract
The utility model provides a pipe bending device for a buckling-pressing type galvanized thin-wall line pipe and relates to the pipe bending device for bending the buckling-pressing type galvanized thin-wall line pipe (KGB) manually. The pipe bending device for the buckling-pressing type galvanized thin-wall line pipe mainly solves the problems that due to the fact that the pipe wall of the buckling-pressing type galvanized thin-wall pipe is very thin, the inner wall of the pipe will be deformed severely if pipe bending operation is carried out directly, the bent portion is not in circular arc connection, an angle needing to be bent cannot be achieved, and even breakage of the line pipe is caused. According to the pipe bending device for the buckling-pressing type galvanized thin-wall line pipe, sleeves are welded at the two ends of a spring respectively, and the other ends of the sleeves are connected with handle rods respectively. When used, the pipe bending device for the buckling-pressing type galvanized thin-wall line pipe is arranged in a buckling-pressing type galvanized thin-wall line pipe needing to be bent, the line pipe can be maintained to be not bent flatly in a certain range through the spring in the pipe, and the line pipe can be bent to form multiple circular arc connection angles. The pipe bending device for the buckling-pressing type galvanized thin-wall line pipe is simple in structure and convenient to operate, ensures the fact that the line pipe will not be broken when bent, can enable the bent portion to be a circular arc and can further form multiple bend angles, and thus all kinds of angles needed by bending of line pipes can be met.
Description
Technical field
The utility model relates to a kind of zinc-plated thin-walled spool pipe bender, relates to specifically the zinc-plated thin-walled spool of a kind of attaching type pipe bender that uses when the spool of building, highway and railway is laid concentrated manual bend pipe.
Background technology
When laying the electric wiring operation, often need to use the zinc-plated thin-walled spool of attaching type (KGB) daily.Because the zinc-plated thin-walled spool of attaching type (KGB) tube wall is very thin, can't uses mechanical angle pipe equipment, so need the zinc-plated thin-walled spool of manual bending attaching type (KGB) during operation.But directly bend pipe tends to cause inside pipe wall because of the unbalance stress gross distortion, cause the position that is bent to become protruding sharp angles, rather than arc angle, the more serious zinc-plated thin-walled spool of attaching type (KGB) that also might make ruptures, such spool very easily causes electric wire insulation layer incised wound in the pipe, causes electrical circuit fault.Do not reach the protection purpose of the zinc-plated thin-walled spool of attaching type (KGB), and cause certain loss.
Summary of the invention
Order of the present utility model is for above-mentioned deficiency, and the place that can guarantee the bending of zinc-plated thin-walled spool that proposes is circular-arc, fracture can not appear, make the zinc-plated thin-walled spool of crooked attaching type can reach the requirement of producing and keeping in repair, and the zinc-plated thin-walled spool of the attaching type of convenient operation and maintenance pipe bender.
Technical solution of the present utility model is: the zinc-plated thin-walled spool of attaching type pipe bender is that the two ends of spring are welded with respectively sleeve, and the other end of sleeve is connected with handlebar respectively.
The external diameter of the sleeve described in the technical solution of the present utility model is consistent with the internal diameter of spring.
The utility model is simple in structure, during use the utility model is placed on the effect that just can improve the zinc-plated thin-walled spool of manual bending attaching type (KGB) in the zinc-plated thin-walled spool of attaching type (KGB).Can guarantee that the zinc-plated thin-walled spool of attaching type after the bending reaches needed angle of bend, the place that is bent is circular arc, the situation of the zinc-plated thin-walled spool fracture of attaching type can not occur, in addition easy operating and maintenance.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model is by spring 1 and two sleeves 2, and two handlebars 3 consist of, two sleeves 2 are fixed on respectively the two ends of spring 1 in the mode of welding, the other end of two sleeves 2 is connected with handlebar 3 respectively, spring 1 can be selected the 50crVA material, can be 400mm in the length without the effect lower spring 1 of external force, the external diameter of sleeve 2 is consistent with the internal diameter of spring 1, the external diameter of sleeve 2 is all little 3 millimeters than spool internal diameter with the internal diameter of spring 2, being convenient to both welds together, on the sleeve 2 with internal thread, sleeve 2 by the internal thread on it be threaded with externally threaded handlebar 3, the length of sleeve 2 is difficult for oversize, is stuck in the place that spool is bent when extracting out in the spool that is bent when preventing from using.
During use, operating personnel hold first handlebar 3 the utility model are put into the zinc-plated thin-walled spool of the attaching type that will be bent (KGB), after placing the utility model, operating personnel just can begin to have carried out the operation of the zinc-plated thin-walled spool of manual bending attaching type (KGB).When the zinc-plated thin-walled spool of crooked attaching type (KGB), operating personnel are should be as far as possible in addition crooked with larger radius, firmly want slowly steadily.Because the effect of spring 1, can keep the zinc-plated thin-walled spool of attaching type (KGB) can be by curved not flat in certain scope.And spring 1 has good elasticity, so that the zinc-plated thin-walled spool of the attaching type that is bent (KGB) can reach multiple angle of bend, and the bend pipe operation of the differently curved angle of can satisfying the demand.After the zinc-plated thin-walled spool of crooked attaching type (KGB) finishes, the handlebar 3 of an end is outwarded winding, make it to separate with sleeve 2, the handlebar 3 of directly holding the other end just can pull out whole device very easily in the zinc-plated thin-walled spool of attaching type (KGB).
Claims (2)
1. the zinc-plated thin-walled spool of attaching type pipe bender, it is characterized in that: the two ends of spring (1) are welded with respectively sleeve (2), and the other end of sleeve (2) is connected with handlebar (3) respectively.
2. the zinc-plated thin-walled spool of attaching type according to claim 1 pipe bender, it is characterized in that: the external diameter of described sleeve (2) is consistent with the internal diameter of spring (1).
