Abstract
The utility model provides a steel pipe bender which is obtained by improvement on a plate winding plate and is capable of being used for bending a steel pipe. The steel pipe bender has the capabilities of reducing production cost and improving machining efficiency when being used for bending the steel pipe. The steel pipe bender comprises a plate winding machine provided with an upper roller and a lower roller, wherein an upper die and a lower die are respectively arranged on the upper roller and the lower roller; and an upper annular groove of which a generatrix is a arc-shaped line is formed in the periphery of the upper die, a lower annular groove of which a generatrix is an arc-shaped line is formed in the periphery of the lower die, and the generatrix of the upper annular groove and the generatrix of the lower annular groove are of a part of the same circle.
Description
Technical field
Present technique relates to carries out crooked bending machine to steel pipe.
Background technology
Existing shaped steel and tube bending generally adopt stretch bending method or shaped steel bending machine method; These two kinds of methods all need special equipment, and the equipment purchasing fund is big, and utilization rate is not high, has increased many burdens to enterprise.And external coordination bends needs certain process-cycle, consuming time longer, has also increased freight and time.
Summary of the invention
The purpose of present technique provides a kind of tube bending machine that obtains, can carry out bending to steel pipe that on veneer reeling machine, improves, and uses it that steel pipe is carried out bending, can reduce production costs, and improves working (machining) efficiency.
This tube bending machine comprises the veneer reeling machine with top roll and lower roll, on top roll and lower roll, is respectively arranged with upper die and lower die; Having bus on the patrix periphery is the last annular groove of camber line, and having bus on the counterdie periphery is the following annular groove of camber line, and the bus of last annular groove is the part of same circle with the bus of following annular groove.
The beneficial effect of present technique: veneer reeling machine divides three rolls plate bending machine and four-roll plate bending machine from the roller number.Existing with common its operation principle of three rolls plate bending machine explanation.Top roll acts on piston in two lower rolls central authorities symmetric position through the hydraulic oil in the hydraulic cylinder and makes vertical displacement movement, and the final stage gear driven two lower roll gears engaged through main gear reducer rotate, and for rolling sheet material moment of torsion are provided.The smooth plastic metal plate of specification passes through between three working rolls (two lower rolls, a top roll) of veneer reeling machine; By pressing down of top roll and rotatablely moving of lower roll; Make metallic plate through the multi-pass continuous bend; Produce nonvolatil plastic deformation, roll into needed garden tube, awl tube or their part.Present technique is that the veneer reeling machine that utilizes each enginerring works generally to have carries out the crooked prefabricated of shaped steel, steel pipe.In order to make plate shearing machine to carry out bending to steel pipe, present technique has increased patrix with last annular groove and the counterdie with following annular groove.During use, extend into steel pipe between annular groove and the following annular groove and can carry out bending steel pipe.So present technique is carried out simple modifications to veneer reeling machine and obtained, can carry out crooked equipment to steel pipe, uses it that steel pipe is carried out bending, production cost is low, and working (machining) efficiency is high.
Above-mentioned tube bending machine, the bus of the bus of last annular groove and following annular groove is the camber line that is not more than semicircle.
Above-mentioned tube bending machine, upper die and lower die are detachably connected on respectively on top roll and the lower roll.
Description of drawings
Fig. 1 is the sketch map of tube bending machine.
The specific embodiment
Referring to tube bending machine shown in Figure 1, comprise veneer reeling machine with top roll 1 and lower roll 2, on top roll and lower roll, be removably connected with patrix 3 and counterdie 4 respectively.Having bus on patrix 3 peripheries is the last annular groove 5 of camber line, and having bus on counterdie 4 peripheries is the following annular groove 6 of camber line, and the bus 7 of last annular groove is the part of same circle with the bus 8 of following annular groove.The bus of the bus of last annular groove and following annular groove is the camber line that is slightly less than semicircle.
Present technique adopts simple die (upper die and lower die) to install as the veneer reeling machine annex, and installation mold bends when needs, removes mould when not required and carries out roll bending.Mold attachment is made simple, and material is easy to get, and cost is extremely low.This tube bending machine improves on the basis of veneer reeling machine and gets, and has improved utilization rate of equipment and installations, has eliminated external coordination cost and time.
