Description
The utility model relates to a kind of follow-on bending machine structure.
Bending machine commonly used is provided with head 12 as shown in Figure 6 on board 11, utilize actuated element 121 drives of bottom to make whole toggling device 13 and outwards action of main mould wheel 122; Be provided with fixedly die holder 14 near head 12 and toggling device 13, oil hydraulic cylinder 141 drives the derivation mould 143 of slide block 142, and corresponding with back guided mode 144; This toggling device 13 utilizes oil hydraulic cylinder 131 to drive curved mould 133 actions of slide block 132.Board 11 is provided with slide rail 15 and establishes feeder 16 for group, but the chuck 17 clamping working substances before this feeder 16 advance.
When carrying out the bend pipe operation, utilize chuck 17 clamping tubing one end earlier, end then places on the main mould wheel 122 in addition, utilize curved mould 133 stablize clamping, restart actuated element 121, make main mould wheel 122 and bend mould 133 with toggling device 13 synchronously to extrinsic deflection, and also advanced in unison feeding of feeder 16, make body with the radius of curvature of main mould wheel 122 curved arc gradually, simultaneously, cooperate the closing guiding of derivation mould 143 and back guided mode 144 and form required bend pipe.Its major defect is:
(1) regardless of the radius of bend pipe, each size is all essential make a main mould wheel can, so the manufacturing cost of mould is quite high;
(2) during the bend pipe operation, front end must stay one section size to make clamping usefulness for main mould wheel and curved mould, forms straight-run of pipe and excises, both bothers, and increases cost again.
(3) derivation mould and back guided mode give this workpiece of closing clamping and are subjected to the promotion of feeder and advance, and it is advanced is direct hard friction fully, is easy to injure tube surfaces or produces serious scratch.
(4) for the bend pipe operation of two angles of need, when being 90 ° or other angles as first curved arc and second curved arc, the essential shutdown when curved second curved arc, and could process again after proofreading and correct size again, finished product accuracy is wayward, and cost is higher.
(5) the curved arc angle is crossed the workpiece more than 180 °, owing to be subject to main mould wheel clip in the curved arc place, thus be difficult for taking off workpiece, even cause the workpiece clashing and breaking.
The purpose of this utility model is to provide a kind of follow-on bending machine structure, by the movable mould wheel that is pivoted of activity on the head, the contact workpiece that cooperates the eccentric curved mould wheel that is provided with on the toggling device, make workpiece produce curved arc, overcome the drawback of prior art, reach reduce die cost, malleable bending range, surface of the work is smooth and the purpose that reduces cost.
The purpose of this utility model is achieved in that a kind of bending machine structure, board is provided with head, feed mechanism, fixedly die holder, toggling device and actuated element, it is characterized in that: movable group is established movable mould wheel on the driving axle center of head, be provided with curved mould wheel by the fulcrum group in the groove of the slide block of toggling device, should curved mould wheel overlook with movable mould wheel and be the off-centre setting with L spacing, this fixedly establishes at least one auxilliary push boat by the fulcrum group in the slide block groove of die holder.
Should be provided with driving wheel group in auxilliary push boat corresponding section; Movable mould wheel directly is placed on by mesopore and is activity on the driving axle center of head and drives the state of connecing; Should comprise the curved mould that installs strip in the slide block groove of curved mould wheel; This promotion is taken turns in the set slide groove and is comprised the derivation mould that installs strip; Comprise the back guided mode that installs strip in the groove of the pedestal of this driving wheel group.
Major advantage of the present utility model is:
1, the radius of curvature of the curved arc of this structure is the eccentricity L that is cooperated curved mould wheel by this movable mould wheel diameter, comprises that this curved mould wheel and the close degree of movable mould wheel decide, and promptly L is constant, and curved mould wheel is more near movable mould wheel, and the radius of its required bending is littler; Moreover should take turns if outwards swing with toggling device again by curved mould, and can change radius of curvature simultaneously.Therefore, its can be crooked the scope of various different curvature radius quite big, and only adjust relevant position when changing and get final product, the movable mould wheel that does not need to make and change various different-diameters at any time can be reached easily, can effectively save a large amount of Mold Making expenses and running carrying cost.
2, owing to accept the knee foremost, do not needed one section flat segments, removed the trouble of excising flat segments again from, and reduce cost for the clamping drawing.
3, all adopt disc wheel against reaching crooked mould, are easy to the advantage except that having processing and manufacturing, do not have any pressure drawing and direct friction part when processing is crooked, so the smooth surface after processing is difficult for being undermined modification.
Front end is no longer forced the clamping drawing when 4, crooked, and feeder still can rotate required angle as workpiece forward simultaneously except that the function that pushes, so any workpiece all can be made plural bending position, and does not need to take off midway and can reach; Even two knees are different angles also together.
5, any one pipe bent position can possess different curvature radius simultaneously, as semiellipse or parabola ... Deng, under the situation of not changing movable mould wheel, only need to change curved mould wheel against pressure or change offset and can reach required curved arc easily, make product processed have more variation, for bending machine in the past can't reach.
6, its bending radius is no longer made decision with the movable mould wheel on the head, so surpass the bend pipe finished product more than 180 °, after processing, be folded on the movable mould wheel not easily detachable situation and almost can avoid fully taking place, because of this movable mould wheel in the mode of minimum diameter for various than the major diameter dimensioned.
7, all discoid each mould wheels all utilize to organize on slide block commonly used and the head and establish, except that can reaching above-mentioned multinomial effect, also these mould wheels can be taken off and change the curved mould of strip commonly used, derivation mould, back guided mode ... Deng recovering traditional operating type, this bending machine is had more use elasticity to deal with different demands.
8, various mould wheels can directly utilize bending machine commonly used directly to change assembling, the important structure of whole bending machine all need not to change, only need change and set the software formula for the CNC type gets final product, no matter be that manufactory or the producer that used all can reach the replacing purpose of upgrading easily, the help of absolute essence is arranged for the quality of industry.
Further specify below in conjunction with preferred embodiment and accompanying drawing.
