Abstract
The utility model belongs to the technical field of mechanical machining tool, in particular relates to a tube bender used for bending the steel pipe with minor diameter and the bend by manually driving with minor diameter. The tube bender is composed of a positioning mechanism, a holding device fixed on the positioning mechanism, and a bending device. The holding device is composed of a guide rod, a sliding rack, a mandrel and a three-jaw self-centering chuck; the bending device is composed of a roller bracket and a roller, a flexure mode and a pull die; the surrounding part of the pull die and the flexure mode is equipped with the grove matched with the outside diameter of the steel pipe. The tube bender of the utility model has the advantages of low bending cost and convenient operational procedures, thus improving the quality and accuracy of the bend.
Description
(1) technical field
The utility model belongs to the technical field of machine tools, particularly is used for the bending machine that minor-diameter steel-tube bends.
(2) background technology
In the machined production process, during to steel tube bending, instrument commonly used is CNC tube bending machine or manual processing.The former is too high cost and the latter can not guarantee machining accuracy, and working (machining) efficiency is lower.
(3) summary of the invention
The purpose of this utility model is to provide a kind of bending machine that is used for minor-diameter steel-tube, makes to bend the cost reduction, and quality and precision improve.
The utility model is realized by following technical measures:
The utility model discloses a kind of manual tube bender, by positioner and be fixed on the clamping device on the positioner and bend device and form, clamping device comprises two parallel guide posts, be fixed on the guide post and can the travelling carriage of move left and right on the guide post, be positioned in the middle of two guide posts and have scale mandrel, be fixed on the travelling carriage and rotary three-jaw self-centering chuck; Bending device comprises the rolling wheel support that moves forward and backward by leading screw and roller, the bending die that can rotate around central shaft and can pull mould around what central shaft rotated; The periphery of pulling mould and bending die has the groove that matches with outer diameter of steel pipes.
Manual tube bender of the present utility model, described bending is equipped with the rotary disk that indicates angular unit on the device, be fixed with handle on the rotary disk.
Manual tube bender of the present utility model, the graduated index dial of mounting strap on the described travelling carriage.
Wherein three-jaw self-centering chuck is fixed on the travelling carriage and can rotates on travelling carriage, and travelling carriage can be on guide post move left and right, rolling wheel support can move forward and backward by leading screw.Pull mould and be in the same place by bolting, (pull mould and can dismantle, change the mould of pulling of different size into) with handle.Can rotate around the central shaft of bending die together with bending die.Handle can move on rotary disk, plays the limited angular effect.
Therefore, bending machine of the present utility model, it is low, easy to operate to have a cost of bending, and has improved the quality and the precision of bend pipe.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is made specific description
Accompanying drawing is a structural representation of the present utility model:
1 three-jaw self-centering chuck, 2 travelling carriages, 3 mandrels, 4 guide posts, 5 rolling wheel supports, 6 handles, 7 pull mould, 8 bending dies, 9 rotary disks, 10 handles, 11 rollers
(5) specific embodiment
As shown in drawings, be the structural representation of present embodiment: by positioner and be fixed on the clamping device on the positioner and bend device and form.Clamping device comprises two parallel guide posts 4, be fixed on the guide post and can the graduated index dial of mounting strap on the travelling carriage 2 of move left and right on the guide post, the travelling carriage, be positioned in the middle of two guide posts and have scale mandrel 3, be fixed on the travelling carriage and rotary three-jaw self-centering chuck 1; Bending device comprises the rolling wheel support 5 that moves forward and backward by leading screw and roller 11, the bending die 8 that can rotate around central shaft and can pull mould 7, indicate the rotary disk (9) of angular unit around what central shaft rotated, be fixed with handle 10 on the rotary disk, the periphery of pulling mould and bending die has the groove that matches with outer diameter of steel pipes.
(diameter is smaller or equal to Φ 15) fixes by three-jaw self-centering chuck 1 with minor-diameter steel-tube, and the handle 6 on the rotation roller support 5 makes roller 11 reaches, and steel pipe is pressed on the bending die 8, so just the steel pipe fixed-site is got off.When bending steel pipe, the pulling handle drives to be pulled mould 7 and bending die 8 and rotates along the central shaft of bending die, and steel pipe and bending die are rotated simultaneously, can bend predetermined angular.When the curved next one is curved, travelling carriage 2 can be moved to mandrel 3 precalculated positions on guide post 4, so just can determine this curved and last distance between curved, rotatable simultaneously three-jaw self-centering chuck 1, make crooked steel pipe that certain space angle be arranged, finish bending of common steel tube.
Claims (3)
1. manual tube bender, by positioner and be fixed on the clamping device on the positioner and bend device and form, it is characterized in that: clamping device comprises two parallel guide posts (4), be fixed on the guide post and can be at the travelling carriage (2) of move left and right on the guide post, be positioned at the mandrel that has scale (3) in the middle of two guide posts, be fixed on the travelling carriage and rotary three-jaw self-centering chuck (1); Bend device and comprise the rolling wheel support (5) that moves forward and backward by leading screw and roller (11), the bending die (8) that can rotate around central shaft and can pull mould (7) that the periphery of pulling mould and bending die has the groove that matches with outer diameter of steel pipes around what central shaft rotated.
2. manual tube bender according to claim 1 is characterized in that: described bending is equipped with the rotary disk (9) that indicates angular unit on the device, be fixed with handle (10) on the rotary disk.
3. manual tube bender according to claim 1 is characterized in that: described travelling carriage (2) is gone up the graduated index dial of mounting strap.
