Description
Technical field
The utility model relates to a kind of bar transmission mechanism.Belong to mechanical equipment technical field.
Background technology
When bar utilizes flying shear or sawing to cut scale on rolling line, end may produce large burr and distortion.Chamfered edge is an important procedure of WIRE FINISHING LINE Wiring technology, adopts the object of chamfered edge to be exactly large burr and the distortion of removing bar end, protects the defect-detecting equipment of postorder, prevent scratch from detecting a flaw and pop one's head in, certainly also improve the presentation quality of bar.In addition, good end is also the automatic labeling of automatic labeling machine, provides basis.Meanwhile, the cutter of the stripper of postorder off-line also will increase the service life greatly.
Bar transmission mechanism plays the effect of conveying bar at chamfering process, existing transmission mechanism adopts propellers to carry out transmission, there is following problem in this transmission mechanism: 1) because chamfered edge line length is fixed, the bar grinding number of turns of small dimension is many, the bar grinding number of turns of large gauge is few, if bar section is of poor quality, user thinks to grind off some overlaps more, only way is exactly the rotary speed reducing propellers, that is increases the grinding depth of individual pen.According to Principle of Grinding and Cutting, one time grinding depth is larger, and ground effect must be poorer, also there will be and beats and instability, and the chamfering machine of therefore propellers transmission can only have one comparatively reasonably to configure to the bar of a certain specification; 2) the bar pace of the chamfering machine of propellers transmission, the chamfered edge number of turns, centripetal force are interrelated, and can not regulate separately, the scope of application is little.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of bar transmission mechanism, this kind of bar transmission mechanism adopts skewed roller mechanisms, vertical roll mechanism and flat roll mechanism to coordinate, need and bar section situation according to client, arbitrarily regulate combination separately, thus making bar grinding even, efficiency is high.
The purpose of this utility model is achieved in that
A kind of bar transmission mechanism, for the conveying of bar in chamfering process, be characterized in: described bar transmission mechanism comprises vertical roll mechanism, first chamfering mechanism and the second chamfering mechanism, described first chamfering mechanism is arranged on bar import department, described second chamfering mechanism is arranged on bar exit, described vertical roll mechanism has multiple and is arranged side by side, the first skewed roller mechanisms is disposed with along bar direct of travel between adjacent two vertical roll mechanisms, flat roll mechanism and the second skewed roller mechanisms, first skewed roller mechanisms is with the second skewed roller mechanisms is positioned opposite and direction of rotation is contrary, described vertical roll mechanism comprises chain, chain is evenly provided with edger roll, bar is placed in the gap of adjacent two edger rolls.
Compared with prior art, the beneficial effects of the utility model are:
1) a kind of bar transmission mechanism of the utility model, skewed roller mechanisms, vertical roll mechanism and flat roll mechanism is adopted to coordinate, three mechanisms are separate, skewed roller mechanisms can adjust rotary speed and the centripetal force of bar, vertical roll mechanism can adjust the pace of bar, therefore need and bar section situation according to client, arbitrarily regulate combination separately, applied widely.
2) a kind of bar transmission mechanism of the utility model, compared with existing spiral transmission mechanism, bar grinding is even, and equipment simple and stable, reliable, spare part expense is low, operating efficiency is high.

Detailed description of the invention
See Fig. 1-2, the utility model relates to a kind of bar transmission mechanism, for the conveying of bar 7 in chamfering process, in Fig. 1, the direct of travel of bar 7 upwards, it comprises the first skewed roller mechanisms 1, vertical roll mechanism 2, flat roll mechanism 3, second skewed roller mechanisms 4, first chamfering mechanism 5 and the second chamfering mechanism 6, described first chamfering mechanism 5 is arranged on bar import department, described second chamfering mechanism 6 is arranged on bar exit, described vertical roll mechanism 2 has five and is arranged side by side, the first skewed roller mechanisms 1 is disposed with along edger roll 2.1 direction of advance between adjacent two vertical roll mechanisms 2, flat roll mechanism 2 and the second skewed roller mechanisms 4, the center line of multiple first skewed roller mechanisms 1 overlaps and is laterally, the center line of multiple Ping Gun mechanism 2 overlaps and is laterally, the center line of multiple second skewed roller mechanisms 4 overlaps and is laterally, the center line of above-mentioned three mechanisms is parallel to each other.Described first skewed roller mechanisms 1 is with the second skewed roller mechanisms 4 is positioned opposite and direction of rotation is contrary, in Fig. 1, the oblique upper right of first skewed roller mechanisms 1, rotate clockwise from B to being seen as, the second oblique bottom right of skewed roller mechanisms 4, rotate counterclockwise from B to being seen as, described flat roll mechanism 3 rotates counterclockwise from B to being seen as, described vertical roll mechanism 2 comprises chain 2.2, chain 2.2 is evenly provided with edger roll 2.1, bar 7 is placed in the gap of adjacent two edger rolls 2.1, and under the effect of chain 2.2, edger roll 2.1 drives bar 7 to advance.
See Fig. 3, when the first skewed roller mechanisms 1 rotates, bar 7 is produced to the power F of oblique bottom right, according to mechanics principle, F is resolved into horizontal power F
1with the F of longitudinal direction
2, F
1for bar 7 provides the centripetal force needed for grinding, F
2bar 7 is rotated, determines the chamfered edge number of turns.
See Fig. 4, the second skewed roller mechanisms 4 operation principle is identical with the first skewed roller mechanisms 1, when the second skewed roller mechanisms 4 rotates, bar 7 is produced to the power F of oblique lower-left, according to mechanics principle, F is resolved into horizontal power F
