Description
Technical field
The utility model relates to a kind of bending tool, especially a kind of plain circular profile bending tool belongs to mechanical system
Make technical field.
Background technique
Currently, the method that round steel or circular pipe workpiece bending operation are realized in each construction site is mainly Heat artificially bending method
Or use dedicated bending mechanical implement.It the disadvantages of these methods multi agent cooperation in need, heating and the higher cost of getting angry, needs to throw
Enter certain human and material resources and time, there are some potential safety problemss, there is certain restriction.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of plain circular profile bending tools, and workpiece is put in U
In the groove of type groove I and U-type groove II, U-type groove I is rotated by handle, bending is carried out to workpiece, operation is simple, improves work
Make efficiency.
In order to solve the above problem, the specific technical solution of the utility model is as follows: a kind of plain circular profile bending tool,
U-type groove I and U-type groove II rotation connection, U-type groove I side wall are fixedly connected with handle, and U-type groove II side wall is fixedly connected with support knot
Structure.It allows U-type groove I to rotate around the axis by operation handle, forms angle with U-type groove II, bending process is completed by axle sleeve to realize
The bending operation of the round section bar of middle small dimension.
The U-type groove I width of rebate is less than the width of rebate of U-type groove II, the lower end surface U-type groove I and U-type groove II notch end
Face contact, U-type groove I and U-type groove II side wall are by shaft through connection, and shaft excircle is set with axle sleeve, and axle sleeve is located at U-type groove
Between the two sidewalls I, axle sleeve and U-type groove I notch have spacing.
The support construction is made of four L-type supports, is respectively fixedly connected with the side wall in U-type groove II in pairs.
The handle is composed of a fixed connection by U-shaped frame and handle, and U-shaped frame two sidewalls are connect with U-type groove I side wall.
The utility model bring has the beneficial effect that workpiece automatic centering, shaft may be implemented in U-type groove II and U-type groove I
Upper shaft sleeve can be moved along shaft axis, can more preferably realize " with curved " in the multiple bending process of workpiece and automatic centering spy
Property, so that IIU type groove, U-type groove I, axle sleeve and workpiece Impact direction is immobilized, protection workpiece material intensity makes with extension tool
Use the service life.
Axle sleeve is cased in shaft, axle sleeve is high-intensitive material, can be very good protection shaft, avoids shaft in the straight of workpiece
Contact, extends the service life of shaft, and axle sleeve is that one of applicator member is vulnerable part, and shaft is installed on tool using bolt,
Facilitate the disassembly and replacement of axle sleeve.
1 end of U-type groove is equipped with handle, can be convenient the operational requirements of operating personnel while increasing the arm of force.
Detailed description of the invention
Fig. 1 is a kind of plain circular profile bending tool structure chart.
Wherein, 1- handle, 1-1-U type frame, 1-2- handle, 2-U type groove I, 3- axle sleeve, 4- U-type groove II, 5- shaft, 6- branch
Seat.
Specific embodiment
A kind of plain circular profile bending tool as shown in Figure 1, U-type groove I2 and U-type groove II4 rotation connection, U-type groove I2
Side wall is fixedly connected with handle 1, and U-type groove II4 side wall is fixedly connected with support construction.
The U-type groove I2 width of rebate is less than the width of rebate of U-type groove II4, the lower end surface U-type groove I2 and U-type groove II4 slot
By shaft 5 through connecting, 5 excircle of shaft is set with axle sleeve 3, axle sleeve for the contact of mouth end face, U-type groove I2 and U-type groove II4 side wall
3 between the two sidewalls U-type groove I2, and axle sleeve 3 and U-type groove I2 notch have spacing.
The support construction is made of four L-type supports 6, is respectively fixedly connected in pairs in the side of U-type groove II4
Wall.
The handle 1 is composed of a fixed connection by U-shaped frame 1-1 and handle 1-2, the two sidewalls U-shaped frame 1-1 and the side U-type groove I2
Wall connection.
Workpiece is placed among U-type groove I2, U-type groove II4 curved bottom and axle sleeve 3, is pressed from both sides between change U-type groove I2 and U-type groove II4
Angle applies the bending that pressure realize round section bar by 3 points of U-type groove I2, U-type groove II4 and axle sleeve 3, can one man operation, drop
Low cost, it is time saving and energy saving, it is convenient and efficient.
The arcuate shape of U-type groove II4 and U-type groove I2 may be implemented workpiece automatic centering, and 5 Upper shaft sleeve 3 of shaft can be along turning
Axis axis is mobile, can more preferably realize " with curved " and automatic centering characteristic in the multiple bending process of workpiece, make U-type groove II4, U
Type groove I2, axle sleeve 3 and workpiece Impact direction immobilize, protection workpiece material intensity and the service life for extending tool.
Axle sleeve is cased in shaft, axle sleeve is high-intensitive material, can be very good protection shaft, avoids shaft in the straight of workpiece
Contact, extends the service life of shaft, and axle sleeve is that one of applicator member is vulnerable part, and shaft is installed on tool using bolt,
Facilitate the disassembly and replacement of axle sleeve.
The end U-type groove I2 is equipped with handle 1, can be convenient the operational requirements of operating personnel while increasing the arm of force, can
Labour protection function is realized to install rubber cover additional on control stick, and controls is also designed to telescopic rod, to meet not
With the demand of operation intensity.
Rotation axis and force-reducing mechanism can be installed additional on U-type groove I2, or install transmission shaft U-type groove II4 and U-type groove I2 additional and lead to
It crosses gear or sprocket wheel cooperation rack gear or chain is driven, provide driving force machine by motor to reduce labor intensity.
Above-described is only the preferred embodiment of the utility model.It should be pointed out that for the ordinary skill people of this field
For member, without departing from the principle of this utility model, several variations and modifications can also be made, also should be regarded as belonging to this
The protection scope of utility model.
