Abstract
A double-guidance piston rod set comprises an oil cylinder, lock member regulating screws and a hood. A piston rod is disposed in the center of the oil cylinder. The hood is disposed on the lower portion of the oil cylinder outside the piston rod. Two sides of the piston rod are milled into flat surfaces. An inner cavity of the hood and the flat surfaces on two sides of the piston rod are provided with lock members respectively. A lock member fixing screw is disposed in the middle of each of the lock members on two sides, and two lock member regulating screws are disposed on two sides of each lock member. A multifunctional combined punching and shearing machine with the double-guidance piston rod set is DIW-200L and DIW-250L typed, 35mm in punching thickness, 45mm in maximum diameter and 250KN in punching force. The cylinder piston rod at the punching position of the punching and shearing machine is double-guided, so that when the oil cylinder operates for punching of irregularly-shaped holes and bending, rotation of the piston rod is avoided. Therefore, die damage is avoided, and normal operation of the machine is guaranteed.
Description
Technical field: the present invention relates to punching and shearing machine, particularly relate to a kind of pair of guide piston bar that the oil cylinder in the punching position adopts in the punching and shearing machine.
Background technology: domestic multifunctional combined punching and shearing machine, maximum model is IW-140T, punching
Process thick 28 mm, maximum gauge 38 mm, stamping press are 140KN.Punching position in the punching and shearing machine is when rushing irregularly-shaped hole and bending, and oil cylinder is in running, and piston rod can rotate, and often understands mold damage, makes the punching and shearing machine cisco unity malfunction.
Summary of the invention: purpose of the present invention is exactly the piston rod that a kind of two guiding will be provided,
It can overcome the existing above problem of present multifunctional combined punching and shearing machine.The object of the present invention is achieved like this, and a kind of piston rod of two guiding comprises that oil cylinder, spline part adjustment screw, cover body form, and is characterized in that: the central authorities of oil cylinder are provided with the match bar of living, and the below of the outer ring oil cylinder of the match bar of living is provided with cover body; Described piston rod two side millings are flat, and the inner chamber of cover body and the flat place of piston rod two side millings respectively are provided with a spline part, and are provided with spline part hold-down screw, both sides in the centre of both sides spline part a spline part adjustment screw respectively is set.It is DIW-200L, DIW-250L that the present invention produces multifunctional combined punching and shearing machine model, and punching processing is thick
35 mm, maximum gauge 45 mm, stamping press are 250KN.Cylinder piston rod to punching and shearing machine punching position has adopted two guiding, and oil cylinder is in running when having guaranteed to rush irregularly-shaped hole and bending, and piston rod can not rotate, can mold damage thereby reach not, guarantee the effect of machine normal operation.
Description of drawings:
Fig. 1 is the front view in the structural representation of the present invention;
Fig. 2 is the left view in the structural representation of the present invention;
Fig. 3 is that Fig. 2 A is to the piston rod schematic diagram;
1. oil cylinder, 2. spline part adjustment screw, 3. cover body, 4. piston rod, 5. spline part, 6. spline part hold-down screw.
The specific embodiment: the invention will be further described below in conjunction with accompanying drawing;
A kind of piston rod of two guiding comprises that oil cylinder 1, spline part adjustment screw 2, cover body 3 form, and is characterized in that: the central authorities of oil cylinder 1 are provided with the match bar 4 of living, and the below of the outer ring oil cylinder 1 of the match bar 4 of living is provided with cover body 3; 4 liang of side millings of described piston rod are flat, and 4 liang of flat places of side milling of the inner chamber of cover body 3 and piston rod respectively are provided with a spline part 5, and are provided with spline part hold-down screw 6, both sides in the centre of both sides spline part 5 a spline part adjustment screw 2 respectively is set.During implementation, such as Fig. 2, shown in Figure 3, cylinder piston rod of the present invention adopts the both sides facing cut flat, and the cover body that is connected with the oil cylinder lower end adopts the two inboard dress spline parts of pressing, and adopt a spline part hold-down screw to fix on the spline part of both sides, both sides are provided with the structure of spline part adjustment screw.Changed in the past that the punching oil cylinder only adopts a facing cut flat, the situation of single face guiding.Both sides spline part can make cylinder piston rod in running, can not rotate.Guarantee punching position upper and lower mould, particularly shaped die, after mould, can positioning.Effectively reduce mould and the phenomenon damaged in use occurs, greatly reduce the generation of punching and shearing machine contingency in running, improved safety and the reliability of the operation of punching and shearing machine.
