Description
Technical field
The utility model relates to the structure field of punching machine three-roller centering unit, is specially a kind of structure of three rollers centering unit opening hydraulic cylinder device.
Background technology
In seamless steel tubing mill's punch design, the punch backstage can be provided with some groups three roller centering units.As shown in Figure 1, it is made up of frame 1, opening hydraulic cylinder 2, oscillating motor 3, three guide rollers 4, three groups of related four-bar linkage structures 5 etc.Wherein oscillating motor 3 is controlled armful push rod and the big opening action of three rollers centering unit guide roller 4, the little opening action of opening hydraulic cylinder 2 control guide rollers 4.Before the drilling/rolling, make guide roller 4 hold push rod tightly, guarantee that the top is positioned at the predeterminated position on the rolling centerline, i.e. centering effect by oscillating motor 3 drive link; In the drilling/rolling, by opening hydraulic cylinder 2 drive link guide roller 4 is opened for a short time, three guide rollers are clamped hollow billet 6, are hollow billet 6 guiding, and hollow billet 6 is advanced along rolling direction is stable; Behind the drilling/rolling, three rollers centering unit guide roller 4 is opened greatly, and hollow billet 6 separates with push rod, dials from roll line from the side for hollow billet 6 and abdicates the space.In the production process,, promptly to control the action that guide roller 4 is opened for a short time, it can be advanced for the rotation of hollow billet 6 do guide effect, and the degree that control guide roller 4 is opened for a short time be by the opening degree 13 size decisions of opening hydraulic cylinder 2 because rolling specs needs often to change.The structure that present existing control guide roller opening degree is an opening hydraulic cylinder opening degree has two kinds:
A kind of is to adjust the opening degree of opening hydraulic cylinder through adjusting three rollers centering unit bottom spiral lift height.See Fig. 1, the shortcoming of this structure is: because spiral lift is installed on the bottom of three rollers centering unit, layout is compact before and after the some groups three roller centering units, and inconvenient production operation personnel carry out the adjustment work of opening degree; In addition, because of the corrosion of guide roller cooling water, be prone to cause that spiral lift is stuck can't go up and down.These cause opening hydraulic cylinder opening degree not reach manufacturing technique requirent or the production adjustment is consuming time too many, inefficiency;
Second kind of structure is that position sensor (like the magnetostriction type position sensor etc.) is equipped with in opening hydraulic cylinder inside, and the closed-loop control system formed of electric-control system such as proportion of utilization reversal valve is controlled the opening degree of opening hydraulic cylinder.The shortcoming of this structure is: proportional reversing valve on the price than high times of common reversal valve (generally more than 10 times), and the fault rate of proportional reversing valve control system and maintenance requirement be also than high times of common reversal valve, input cost is higher.
Summary of the invention
There are the problems referred to above in opening degree adjustment to existing two kind of three roller centering unit opening hydraulic cylinder; The utility model provides a kind of structure of three rollers centering unit opening hydraulic cylinder device; Its opening degree adjustment of having guaranteed three rollers centering unit opening hydraulic cylinder is quick, reliable; Enhance productivity, and simple and compact for structure, use cost reduces greatly.
The technical scheme that the utility model adopts is: a kind of structure of three rollers centering unit opening hydraulic cylinder device; It comprises the opening hydraulic cylinder; It is characterized in that said opening hydraulic cylinder is two rod hydraulic cylinders of size diameter, the size diameter piston rod of said opening hydraulic cylinder is a unitary piston rod; The end of said opening hydraulic cylinder piston rod path is provided with the opening degree adjusting device, and the end in the big footpath of said opening hydraulic cylinder piston rod connects the frame earrings.
It is further characterized in that: said opening degree adjusting device comprises clamp, following clamp, outer adjustment head, interior adjustment head, adjusts backing plate; The first end external screw thread rotation of adjustment is fixed in the first end internal thread hole of said outer adjustment in said; Said adjustment backing plate be fixed on said outer adjustment head thread end face with said in the annular groove that contains between the adjustment head thread end face, the other end of said outer adjustment head is through said clamp down, said upward clamp and half-and-half block key and cover the end that is fixed on said opening hydraulic cylinder piston rod path; The said clamp of going up contact with said clamp down and is provided with annular groove between end face, said on clamp and said clamp down through said end of half-and-half blocking key and said annular groove matching and fixing at said opening hydraulic cylinder piston rod path; Said clamp down and the said clamp of going up are fixedly connected sequentially through soket head cap screw, hexagon slotted nut, elastic washer and split pin; Said adjustment backing plate for have certain thickness two to the semi-round ring shape backing plate; Respectively be provided with tool mounting hole on a said outer adjustment head and the said interior adjustment cylindrical end face; Said tool mounting hole is a pair of circular hole that certain depth is arranged, said circular hole symmetric arrangement; The end in the big footpath of said opening hydraulic cylinder piston rod connects the frame earrings through the card key; Said opening hydraulic cylinder is provided with annular groove at the rear end cap rear portion of piston rod path side, is fixed with beam through soket head cap screw in the annular groove of said rear end cap rear portion, and said beam exposes to the annular groove at said rear end cap rear portion; Said beam material is a polyurethane.
The utility model adopts after the said structure; Because the end of opening hydraulic cylinder piston rod path is provided with the opening degree adjusting device; Carry out the opening degree adjustment when greatly having made things convenient for the production operation personnel to change rolling specs, and avoided corrosion to cause stuck phenomenon, production efficiency improves greatly; This is simple and reliable for structure simultaneously, greatly reduces the maintenance requirement and the cost of opening degree adjusting device.
