Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail。
A kind of double-strand drawbench with automatic discharging function, as shown in fig. 1, include motor 1, decelerator 2, frame 3 and be arranged on the chain-drive mechanism in frame 3, frame 3 is additionally provided with draw trolley 6, its operation principle is described below: the rotating speed of motor 1 output enters the power shaft in decelerator 2, export two by decelerator 2 to move in two frames 3, illustrate its structure and operation principle for one of them chain drawbench。The chain-drive mechanism arranged in frame 3 includes sprocket wheel 40 and driving-chain 41, and the output shaft of decelerator 2 directly drives the sprocket wheel 40 in two frames 3 to rotate, the motion rotating driving driving-chain 41 of sprocket wheel 40, drives draw trolley 6 to link with it。Frame 3 is provided with regular jaw 5, regular jaw 5 maintains static in frame 3, operator will treat penstock installation that drawing the processes position to regular jaw 5, draw trolley 6 is clamped the other end of steel pipe, when steel pipe all clamp with between the two after, the further athletic meeting of draw trolley 6 is by steel pipe drawing to designated diameter。
More specifically, draw trolley 6 includes base plate 600, base plate 600 stretches steel pipe with driving-chain 41 linkage driving draw trolley 6 with regular jaw 5 relative movement。Base plate 600 goes out to have external part 620 towards spatially extended between two frames 3。Base plate 600 is provided with clamp system 601, shearing mechanism 602 and moving jaw 610, wherein moving jaw 610 belongs to a part for clamp system 601, moving jaw 610 includes again left pincers 611 and right pincers 612, and both of which is completed the pinching action to steel pipe by Driven by Hydraulic Cylinder。Wherein, being provided with block 9 on base plate 600, when left pincers 611 prop up block 9, clamp system 601 is directed at regular jaw 5, serves and can start to drive draw trolley 6 to carry out drawing action。After shearing mechanism 602 is arranged on clamp system 601, after completing drawing, when clamp system 601 is in clamping, shearing mechanism 602 works and is cut off by steel pipe。
In order to realize automatic discharging, after completing to cut off, left pincers 611 continue to stretch out towards right pincers 612 direction, and right pincers 612 retreat with identical speed, make the steel pipe cut off continuously move on external part 620 with clamp system 601, on external part 620, the formation destination county corresponding to left pincers 611 and right pincers 612 is provided with ejecting mechanism 603, after clamp system 601 moves to the predetermined area, left pincers 611 return and unclamp steel pipe, and ejecting mechanism 603 is pushed ahead, steel pipe is ejected, completes discharging action。Ejecting mechanism 603 can adopt cylinder as shown in Figure 2, linkage external connection power source can also be adopted to realize, or it is connected in same hydraulic circuit to utilize hydraulic cylinder to realize together with left pincers 611 and right pincers 612, wherein, preferably employ pneumatic linear actuator to realize, utilize pneumatic quick features of response, improve the efficiency of discharging。
Owing to the feature of double-strand drawbench is that two chain-drive mechanisms drive with by motor 1, thus, the production efficiency of the steel pipe on two drawbench is similar, so, be equivalent to two drawbench work simultaneously, in order to collect the steel pipe that drawing completes, between two frames 3, it is provided with collecting box 7, in order to collect the steel pipe that ejecting mechanism 603 completes from the drawing ejected external part 620。
Specifically, as shown in Figure 2, collecting box 7 includes the first flanging 71, weight tray 72 and swash plate 73, three in one molding, wherein, the first flanging 71 is overlapped on the edge of two frames 3, weight tray 72 is for supporting the steel pipe of discharging, swash plate 73 is arranged on the first flanging 71 between weight tray 72, in order to lead to the steel pipe unloaded so that it is tumble from swash plate。
As preferably, the length of collecting box 7 is identical with the move distance of draw trolley 6, to prevent its curtailment, leaves gap between the discharge pit and regular jaw 5 of steel pipe。
As preferably, as shown in Figure 3, draw trolley 6 is provided with follower 80 and guide rail 81, both are collectively forming guider, the effect of guider is to 6 one motion guides of draw trolley, owing to the driving mechanism of draw trolley 6 is chain-drive mechanism, owing to driving-chain 41 inevitably also exists polygon effect, thus draw trolley 6 can inevitably tremble therewith in motor process, namely the guider set up is the drawing error in order to overcome vibration to produce。
Specifically, follower 80 includes support 801, roller 805 and rotating shaft (in figure, visual angle is not shown), support 801 includes connecting plate 802, gusset 803 and adjustment screw 804, wherein: connecting plate 802 interfixes integral with the base plate on draw trolley 6, gusset 803 includes orthogonal first connecting plate c and the second connecting plate d, first connecting plate c abuts against the side on connecting plate 802 near guide rail 81, second connecting plate d level is fixed on the underface of draw trolley 6, second connecting plate c is vertically arranged rotating shaft, rotating shaft is worn and penetrates roller 805, when draw trolley 6 moves, roller 805 rolls along guide rail 81, the drawing campaign of draw trolley 6 rises and limits and guide effect。
As preferably, adjust screw 804 and be arranged in the plane that connecting plate 802 and gusset 803 are abutted against, after roller 805 uses a period of time, can inevitably wear and tear, roller 805 or guide rail 81 affect guiding accuracy, at this point it is possible to need not be changed, directly tighten or unscrew the adjustment screw 804 of relevant position, make roller 805 and guide rail 81 ensure correct guiding。
Further, roller 805 includes inner sunken face and positioning cylinder, and wherein inner sunken face is arranged between the positioning cylinder at two ends, and roller 805 is limited on the appropriate location of guide rail 81 by positioning cylinder, it is prevented that it is along rotating shaft play。Contact form between roller 805 and guide rail 81 can be linear contact lay by inner sunken face so that the guiding accuracy of guider is higher, to improve the drawing precision of steel pipe。Further, the position coordinated with inner sunken face on guide rail 81 is that evagination is cylindrical, to improve the quality of fit of roller 805 and guide rail 81 further, in addition, in order to be fixed in frame 3 by guide rail 81 easily, the side that guide rail 81 is fixed in frame 3 is that plane is arranged。
Further, in order to improve the draw trolley 6 resistivity for the vibration of driving-chain 41, the corner of draw trolley 6 is provided with four assembly guidances。
This specific embodiment is only to explanation of the present utility model; it is not to restriction of the present utility model; the present embodiment can be made the amendment not having creative contribution as required by those skilled in the art after reading this specification, but as long as being affected by the protection of Patent Law in right of the present utility model。
