Detailed description of the invention
The embodiment one of bending machine of the present invention: as Figure 1-3, comprises holder 2, the installation passage extended before and after holder 2 is provided with, and installs in passage and is provided with telescopic oil cylinder 1, and the front end of telescopic oil cylinder 1 i.e. output are provided with top pressure head 3.When the elastic motion of telescopic oil cylinder 1, top pressure head 3 moves in the longitudinal direction.Bending machine also comprises the left and right gear wheel 6 that be fixedly installed relative to holder 2, left and right gear wheel 6 lays respectively at the left and right sides of the mobile route of telescopic oil cylinder 1, left and right gear wheel is used for support work piece being provided to backward directions in use, and such work piece occurs bending and deformation when pushing up pressure head 3 forward direction pushing tow.Top pressure head 3 front end of the bending machine of the present embodiment is arc, and the arc groove being provided with the indent arcuately extended is for adaptive with the outer peripheral face of tubing or bar, and the outer peripheral face of left and right gear wheel 6 is also the arc groove of indent.
In the present embodiment, left and right gear wheel realizes being fixedly installed with the relative of holder by fixed head.The both sides up and down of holder 2 are respectively equipped with upper mounted plate 7 and the bottom plate 5 of horizontal-extending, and upper and lower fixing plate is parallel to each other, and upper and lower fixing plate are respectively equipped with installing hole corresponding up and down to 50.Each installing hole is to comprising two installing holes respectively, and left and right gear wheel is hinged on the corresponding installing hole centering of this upper and lower fixing plate respectively around the axis of upper downward-extension, and right two installing holes of same installing hole are symmetrical about the mobile route of top pressure head.
In order to the different tubing of bending radius or bar can be processed, installing hole on upper and lower fixing plate is to there being two or more, different installing holes is different to the distance between comprised two installing holes, time like this in left and right gear wheel two installing holes that different installing hole is right respectively, distance between the gear wheel of left and right is different, so just cause distance when making it bending at pushing tow tubing or bar between two fulcrums different, bending radius is also with regard to physical alterations.
In addition, in order to measure angle of bend and control, bending machine also comprises pointer 10 and the dial 4 that be fixedly installed relative to holder 2.In the present embodiment, dial 4 is fixed on the upper side of holder 2 by connecting elongated hole 40, and dial 4 is provided with the scale formed by arrangement before and after the scale value of instruction angle of bend and arranges.Wherein, scale on dial 4 shows more than two row and equal to the number of 50 with installing hole, each scale is listed in left and right directions and is set up in parallel, and each row scale row correspond respectively to different installing hole to 50 and are used to indicate the angle of bend of tubing or bar when left and right gear wheel 6 is arranged on corresponding installing hole centering.In the present embodiment, as Figure 2-3, installing hole is six right to having, correspondingly, scale row on dial also have six and represent the first to the 6th installing hole pair by A, B, C, D, E, F respectively, scale row A is corresponded to when left and right gear wheel is arranged on nearest the first installing hole centering of two installing holes, correspond to scale row F when left and right gear wheel is arranged on two installing holes distance the 6th installing hole centering farthest, B, C, D, E, F are corresponding in turn to the second to the five middle installing hole pair.Certainly, in other embodiments, the right number of installing hole can be a pair or two or three pairs of or four right, also can be seven to more than, correspondingly, the equal and one_to_one corresponding of the quantity that the scale number of columns on dial is right with installing hole.
Pointer 10 extends at fore-and-aft direction, and the front end of pointer 10 is connected to the output of telescopic oil cylinder 1, namely with top pressure head 3 synchronizing moving.Push up pressure head 3 movable under the drive of telescopic oil cylinder 1 time, movable and its rear end the is aimed at scale value of pointer 10 is the angle of bend of top movable press head to tubing during current location or bar.Wherein, it is conveniently when original state that dial 4 is connected on holder by connection elongated hole 40, regulates the front and back position of dial 4 to make the rear end of pointer 10 corresponding with the initial scale value of dial 4.The middle part of dial is provided with the gap of front and back extension, and pointer is positioned at gap and moves at fore-and-aft direction.
The tubing be bent or bar are placed on top pressure head and a left side by bending machine of the present invention in use, between right gear wheel, telescopic oil cylinder is driven to stretch out forward, until top pressure head, left, right gear wheel contacts with tubing or bar, dial is regulated to make its initial scale i.e. graduation mark of 180 ° and pointer back-end aligned, continue to drive telescopic oil cylinder to stretch out forward and tubing or bar can be bent, until stop when bending to corresponding scale value, scale value only marks the reading of particular distance, can need to change dial according to reality processing, often pair of corresponding top pressure head in installing hole hole.According to the distance h that telescopic oil cylinder stretches out, the distance 2d between two installing holes that installing hole corresponding during bend pipe is right, can obtain angle of bend
The embodiment two of bending machine of the present invention: be with the difference of embodiment one, holder and fixed head are wholely set.
The embodiment three of bending machine of the present invention: be with the difference of embodiment one, holder is only provided with bottom plate.
The embodiment four of bending machine of the present invention: be with the difference of embodiment one, the cam follower mechanism urges that top pressure head is connected by rear end moves forward and backward.
Bending machine of the present invention can facilitate the angle of bend controlling tubing or bar accurately, simple to operate, easy to use.
