Abstract
The utility model relates to an adjustable pulling clamp for a copper bar hydraulic drawbench, which comprises a piston rod of a main cylinder, a pulling frame fixed with the piston rod, a clamp oil cylinder, a clamp convex block fixed with the clamp oil cylinder, upper and lower clamps fixed on the clamp convex block. The taper of the front end of the clamp is in a clamping state through the taper on the pulling frame, wherein a clamp radial adjusting device is arranged between the clamp convex block and the clamp. The clamp of the utility model has the advantages that the clamp radial adjusting device can be used for adjusting the position of the pulling clamp to ensure the centre line of a die and the centre line of the pulling clamp on the same level. In this way, the flatness of the finished bars can be largely promoted and the technical processes can be reduced. The ends of a 12m coppers bar only can be cut off 50mm, so waste of copper is reduced and the yield is promoted.
Description
Technical field
The utility model belongs to hydraulic drawbench, relates in particular to a kind of adjustable dop of pulling a cart of improved copper bar hydraulic drawbench.
Background technology
It is power that hydraulic drawbench adopts with hydraulic pressure.The drawbench pulling capacity is big, stable action.Especially 63 tons of drawbench effect aspect the particularly special-shaped copper bar of drawing copper bar is very good.Drawbench is by the piston rod in the master cylinder, and the clamping that drives front end pulls a cart to do the reciprocating motion of front and back.When the main oil cylinder piston bar stretches out fully, at this moment clamp the headstock of pulling a cart, will arrive main lathe bed die holder front foremost, from the stretching out of the piston rod of on one's body hydraulic jack dop is clamped by pulling a cart, clamp the copper bar that from mould, has stretched out.Regain the piston rod in the master cylinder then, retract and pull a cart, copper bar by mould drawing moulding, is achieved the drawing of finished product copper bar.The copper bar length that the drawbench drawing goes out is about 12 meters.Copper bar after the drawing must meet the glacing flatness requirement of national standard, must guarantee mold center's line in the production, pull a cart the dop center line both on same horizontal line.Existing equipment can reach production requirement for common rectangle row.But during the special-shaped copper bar on mold center's line, both then can not be on same horizontal line for the production geometric center.The problem that occurs in the actual production is: the first, every drawing goes out the special-shaped copper bar of a 12m, bite the position of copper bar rises at the dop of pulling a cart, the scar that can occur significantly, have feel to the position of die holder direction 250mm, this scar directly influences product quality, must cut off the blanking of the above length of 250mm, cause the waste of raw material, reduce lumber recovery.It two is that the arch that occurs big radian in the horizontal direction easily is curved or sunk curved, does not guarantee the glacing flatness of product, need add artificial straightening operation in addition.Increase unnecessary technical process, increased cost of labor, reduced production efficiency.
The utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and provide a kind of adjustable dop of pulling a cart of copper bar hydraulic drawbench, can regulate the position of the dop of pulling a cart, guarantee mold center's line, pull a cart the dop center line both on same horizontal line, improved finished product row's glacing flatness greatly, reduce the cutting length of finished product copper bar, improved lumber recovery.
The utility model for achieving the above object, by the following technical solutions: a kind of adjustable dop of pulling a cart of copper bar hydraulic drawbench, comprise the piston rod of the master cylinder of pulling a cart and pull a cart framework, dop oil cylinder and with it the affixed dop jacking block affixed with it, be fixed in the dop up and down on the dop jacking block, the tapering of dop front end is clamped condition by the tapering on the framework of pulling a cart, and it is characterized in that: be provided with dop radiai adjustment device between described dop jacking block and the dop.
Described dop radiai adjustment device mainly is made of up and down rectangle parallels and stud and the locknut that is spirally connected with it, described about dop affixed by hex screw and dop jacking block respectively, the via hole of described hex screw and dop jacking block is matched in clearance; Described rectangle parallels up and down and stud are slidingly matched, and stud and dop jacking block are spirally connected.
Beneficial effect: adopt dop radiai adjustment device can regulate the position of the dop of pulling a cart, guarantee mold center's line, pull a cart the dop center line both on same horizontal line, improved finished product row's glacing flatness greatly, reduce technical process, raise the efficiency; The copper bar end that every 12m is one only need cut out 50mm, has reduced the waste of copper material, has improved lumber recovery.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Describe the specific embodiment of the present utility model in detail below in conjunction with accompanying drawing and preferred embodiment.As shown in the figure, a kind of adjustable dop of pulling a cart of copper bar hydraulic drawbench, comprise the piston rod 1 of the master cylinder of pulling a cart and pull a cart framework 2, dop oil cylinder 3 and with it the affixed dop jacking block 4 affixed with it, be fixed in the dop up and down 5 on the dop jacking block, the tapering of dop front end is clamped condition by the tapering on the framework of pulling a cart, and is provided with dop radiai adjustment device between described dop jacking block and the dop.Described dop radiai adjustment device mainly is made of up and down rectangle parallels 6 and stud 7 and the locknut 8 that is spirally connected with it, and described dop up and down is affixed by hex screw 9 and dop jacking block respectively, and the via hole of described hex screw and dop jacking block is matched in clearance; Described rectangle parallels up and down and stud are slidingly matched, and stud and dop jacking block are spirally connected.
Operation principle: since pull a cart with master cylinder for to be connected firmly, the position is unadjustable; Die holder is a fixed form, so that die location also belongs to is fixing, unadjustable, so the position that can regulate has only dop.Added a rectangle parallels between dop oil cylinder and dop, dop respectively fills up one up and down, can adjust the front and back position of dop respectively, that is, and and the radial position of main relatively lathe bed.The rectangle parallels runs through stud, utilizes the nut on the stud to regulate the front and back position of parallels, thereby adjusts the front and back position of dop.For example: when the rectangle parallels that will go up dop to the center position adjustment, the tapering of dop front end is clamped condition by the tapering on the framework of pulling a cart can reach the purpose of regulating the dop center line with dop position skew.Add after the parallels, height that can regulated at will dop center line is adjusted on the same horizontal line dop and mold center's line, and worst error can be controlled in the 0.5mm.Improved finished product row's glacing flatness greatly, it is just passable that the copper bar end that every 12m is cuts out 50mm, improved lumber recovery.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
