Description

A kind of pipe clamping device
Technical field
The utility model relates to the bend pipe manufacture field, particularly a kind of pipe clamping device for the clamping pipe fitting.
Background technology
In the bend pipe process of bending machine, need to carry out clamping to prevent the distortion of pipe fitting in the process to pipe fitting.In clamping process, pipe casting clamp can be subject to very large pressure, and therefore, its actuating unit need to provide enough power to keep the clamping to pipe fitting to pipe casting clamp.Existing bending machine adopts hydraulic jack as the actuating unit of pipe casting clamp usually.Be that 200820187068.5 Chinese utility model patent discloses a kind of clamp head locking device of pipe bender such as the patent No., described device includes connecting lug, two yoke plates and two lock dogs, it is characterized in that having an earrings connecting hole at two lock dogs, lock dog is connected with the yoke plate by the earrings connecting hole, and the initial angle of two yoke plates is 55 to 65 degree.This locking device adopts oil cylinder as actuating unit, the piston rod of described oil cylinder promotes connecting lug, promoting two lock dogs by two yoke plates again moves, thereby the upper and lower clamp sheet locking with the clamp head of bending machine, because when piston rod promotes connecting lug, if the initial angle of two yoke plates is less, piston rod just needs very large thrust when promoting connecting lug, thereby causes the piston rod damage that bends easily.Therefore the start angle of two yoke plates of this clamp head locking device is set to 55 to 65 degree, has so just effectively lowered oil cylinder for the thrust that promotes lock dog, the damage so that piston rod is difficult for bending.
But the pipe clamping device of above-mentioned patent is directly to adopt hydraulic jack as actuating unit, and the power of keeping the pipe fitting clamping is also provided by oil cylinder, and this is damaged easily so that the piston rod of oil cylinder has born larger active force.In addition, adopt hydraulic jack as actuating unit, be difficult for the cleaning of maintenance equipment, also need to be equipped with loaded down with trivial details oil supply system, operating efficiency is also lower.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of energy consumption low for the above-mentioned state of the art, and noise is little, the pipe clamping device of high efficiency.
The utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of pipe clamping device is characterized in that comprising:
One bend pipe pivoted arm, one end are set on the turning cylinder, form along its length a slide rail on the arm face that its level is stretched out;
One takes turns mould, is fixed at the upper end of turning cylinder, the top of bend pipe pivoted arm, offers the first bend pipe die cavity on the wheel mould;
One ball-screw is located in the bend pipe pivoted arm rotationally, and links to each other with actuating unit by transmission device;
One bottom is with the main folder mould of slide block, its sidepiece offer with take turns mould on the first bend pipe die cavity match and realize the second bend pipe die cavity of pipe fitting clamping, described slide block is located on the slide rail of bend pipe pivoted arm slidably, its lower end snail mother set is located on the ball-screw, and under the driving of ball-screw, slide along slide rail, and then drive the feeding of main folder mould.
As improvement, the both sides, bottom of described slide block form the chute of the indent corresponding with slide rail.
Improve, be arranged with a feed screw nut that includes ball on the described ball-screw, the surface of ball-screw offers corresponding raceway, and the lower end of described feed screw nut and slide block joins also can promote the feeding of slide block.
At last, described actuating unit is a motor, and described transmission device is gear drive.
Compared with prior art, the utility model has the advantage of: adopt the clamp pattern of motor driven ball screws feeding to replace traditional hydraulic jack, can guarantee the uniformity of machining accuracy in the running, maintenance and the cleaning of hydraulic system have been saved, energy consumption is low, noise is little, high efficiency.In addition, utilize the characteristic of ball-screw to keep chucking power to pipe fitting, than oil cylinder, better effects and if be difficult for causing the damage of device.

The specific embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
As shown in the figure, a kind of pipe clamping device, comprise main folder mould 1, wheel mould 6, bend pipe pivoted arm 2, ball-screw 3, turning cylinder 7 and actuating unit 4 etc., wherein an end of bend pipe pivoted arm 2 is set on the turning cylinder 7, form along its length a slide rail 21 on the arm face that its level is stretched out, ball-screw 3 is located in the bend pipe pivoted arm 2 rotationally by bearing, such as the below of slide rail 21, and link to each other with gear drive 5, and gear drive 5 links to each other with actuating unit 4; Actuating unit 4 is a motor, and motor is fixed on the sidepiece of gear drive 5, and gear drive 5 places in the bend pipe pivoted arm 2, is connected with an end of ball-screw 3; Wheel mould 6 is fixed at the upper end of turning cylinder 7, the top of bend pipe pivoted arm 2, offer the first bend pipe die cavity 61 on the wheel mould 6, the bottom of main folder mould 1 is provided with slide block 12, its sidepiece offer with take turns mould 6 on the first bend pipe die cavity 61 match and realize that the second bend pipe die cavity 11 of pipe fitting clamping, pipe fitting just are clamped in the through hole that above-mentioned two die cavities form when closed; The both sides, bottom of slide block 12 form the chute of the indent corresponding with slide rail 21, and slide block 12 is located on the slide rail 21 of bend pipe pivoted arm 2 slidably, and slide along slide rail 21 under the driving of actuating unit 4, and then drive the feeding of main folder mould 1; Be arranged with a feed screw nut 31 that includes ball on the ball-screw 3, the surface of ball-screw 3 offers corresponding raceway 32, slide rail 21 is passed in the lower end of slide block 12, joins with the feed screw nut 31 that is set on the ball-screw 3, drives the feeding of slide block 21 by the rotation of ball-screw 3.
