Description
One, technical field
The present invention relates to the numerical controlled bending of pipe processing unit (plant), specifically is a kind of stiffening device of bending machine.
Two, background technology
Because the bend pipe part satisfies the requirement to aspects such as product lightweight, high strength and low consumption easily, has obtained extensive use in high-tech sectors such as aerospace, except that the transfer pipeline that is widely used in gas, liquid, also is widely used as hardware.Along with the development of high-tech sectors such as aerospace, to the demand of bend pipe more and more thin-walled property, heavy caliberization, this maximizes with regard to the corresponding CNC tube bending machine that makes.Yet the pivoted arm weight of large-scale bending machine is very big, and machine tool chief axis is produced a very big moment of flexure, has caused the rotation instability of pivoted arm when bending pipe fitting.(wall thickness is less than 1 millimeter and for the small-bend radius of large-diameter and thin-wall pipes such as stainless steel, aluminium alloy, the wall thickness factor is greater than 40, relative bending radius is less than 2.0) be shaped, because the tube wall thickness factor is big, structural stability is poor, bending needs equipment that good stability is arranged, and the deviation that pivoted arm is small when rotated all may influence the forming quality of pipe fitting, causes generation of defects.And pivoted arm is worked under unsure state for a long time and can be reduced the service life of machine tool chief axis.
Three, summary of the invention
Rotate unsettled deficiency in order to overcome the large computer numerical control pipe bender that exists in prior art pivoted arm when the bending pipe fitting, the present invention proposes a kind of stiffening device of bending machine.
The present invention includes add that stay bolt, two reinforced pull rods, two are inserted, two band handle bolts and two vertical upright arms.The planar ends of two vertical upright arms is separately fixed at pivoted arm and work boss and the upper surface that adds the relative side of stay bolt, and the axis normal that makes two vertical upright arms is in horizontal plane.The shared stay bolt that adds that is set with bending die of one end of two pull bars, the other end is separately fixed at the cavity of inserting that is positioned at two vertical upright arm stepped surfaces, and reinforced pull rod is linked to each other with vertical upright arm by inserting; Two ends are in the reinforced pull rod of inserting and adding on the stay bolt respectively and are in level.Fastening bolt passes on the upright arm that hangs down that the bar shaped installing hole will be inserted and vertical upright arm is connected.
Insert to the block of cavity is arranged, an end of reinforced pull rod is positioned at the cavity of inserting; There is the fixing hole that connects its wainscot and lower wall panels at the middle part of inserting, and the through hole that is positioned at wainscot is an internal thread hole.
The length of band handle bolt screw portion is installed in the fixing hole at the middle part of inserting with the thickness of inserting, and by this band handle bolt with reinforced pull rod and insert fixing.
The surface distributed of the horizontal ends of vertical upright arm has bar shaped installing hole and two installing holes of regulating bolts of four fastening bolts.
During use, by regulate bolt regulate insert and vertical upright arm between position in the horizontal direction, realize adjusting to the reinforced pull rod tightening force.Fixedly insert in the position of vertical direction by fastening bolt, the side surface of inserting is steadily cooperated with vertical upright arm surface; When unclamping fastening bolt, regulate the position that the bolt adjustment is inserted by rotating, thus the tension degree of regulating reinforced pull rod.
The present invention uses the reinforced pull rod device that clamp/bending die, briquetting/wrinkle resistant mould are fixed together, and forms an integral body, has effectively reduced the moment of flexure of pivoted arm to machine tool chief axis, has avoided the instability of duty, has guaranteed the stable bending forming of pipe fitting.The present invention can improve operation stability of equipment, reduces the probability that defective occurs, and has improved pipe fitting bending forming quality, has the advantages that cost is low, applicability is wide.
Four, description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Accompanying drawing 1 is a structural representation of the present invention.
1. add stay bolt 2. reinforced pull rods 3. 4. band handle bolts 5. upright arms that hang down of inserting
6. regulate bolt 7. fastening bolts
Five, the specific embodiment
As shown in fig. 1, present embodiment comprises and adds stay bolt 1, two reinforced pull rods 2, two insert 3, two band handle bolts 4 and two vertical upright arms 5.Wherein, adding stay bolt 1 is that the bolt that assembles bending die on the general elbow machine is extended, so that an end of reinforced pull rod 2 can be enclosed within on the lengthening end of bolt, the length of lengthening end can freely design, and the rotation of pivoted arm is as the criterion when not interfering the bending machine operate as normal; Reinforced pull rod 2 is solid rod members that two ends have the collar, and the cross sectional shape of bar can be chosen arbitrarily as required, usually for the rectangular shaft that adopts easy to assembly; Insert 3 for the U-shaped block part, and the height of U-shaped cavity is greater than the thickness of reinforced pull rod 2, formed reinforced pull rod 2 and 3 the U-shaped cavity inserted between fit clearance; There is the fixing hole that connects its wainscot and lower wall panels at insert 3 middle part, and the through hole that is positioned at wainscot is an internal thread hole.
The upright arm 5 that hangs down has two, is T shape rod member.The horizontal ends of upright arm 5 of hanging down is horizontal L shaped, inserts 3 to be positioned on this L shaped horizontal plane, and in the both sides of L shaped horizontal plane, is distributed with the bar shaped installing hole of four fastening bolts 7; The length direction of bar shaped installing hole is with the opening direction of the 3U shape cavity of inserting.On this L shaped vertical plane, be distributed with two installing holes of regulating bolt 6.As shown in Figure 2.
During use, the planar ends of two vertical upright arms 5 is separately fixed at pivoted arm and work boss and the upper surface that adds stay bolt 1 a relative side, and the axis normal that makes two vertical upright arms 5 is in horizontal plane.With an end of two pull bars shared be set with bending die add stay bolt 1, the annulus of the other end then is contained in the cavity of inserting that is positioned at two vertical upright arm 5 stepped surfaces respectively, and fixing by band handle bolt 4, reinforced pull rod 23 is linked to each other with vertical upright arm 5 by inserting; Two ends be in respectively insert 3 and the reinforced pull rod 2 that adds on the stay bolt 1 be in level.Fastening bolt 7 passes on the upright arm 5 that hangs down the bar shaped installing hole and will insert and 3 be connected with vertical upright arm 5.
As shown in Fig. 1 and Fig. 2.During use, by regulate bolt 6 regulate insert 3 with vertical upright arm 5 between position in the horizontal direction, realization is to the adjusting of reinforced pull rod 2 tightening forces.Fixedly insert 3 in the position of vertical direction by fastening bolt 7,3 one side surfaces of inserting are steadily cooperated with vertical upright arm 5 surfaces; When unclamping fastening bolt 7, adjust 5 the position of inserting by rotate regulating bolt 6, thus the tension degree of regulating reinforced pull rod 2.
