Abstract
The utility model relates to a kind of bar combined type flying shear and cuts arm positioning sleeve, comprise location skewback, an annular sleeve is studded with outside this skewback upper end, location, this location skewback with adopt between annular sleeve integrated be connected, be that alignment pin plays and leads and look for position to act on when can be fitted on the inclined-plane of locating skewback and alignment pin end face by this annular sleeve, by the pretightning force of alignment pin holding screw, two inclined-planes are adjacent to completely, alignment pin just can be made to realize effective location.During installation flying shear tool rest, alignment pin can find the installation site of a life cycle exactly, avoids and repeatedly adjusts blade clearance, substantially reduces the activity duration that flying shear changes shearing work pattern.
Description
Technical field
The utility model belongs to rolling equipment technical field, relates to a kind of bar combined type flying shear and cuts arm positioning sleeve.
Background technology
Aborning because technological process needs, finished product or semi-finished product are when by flying shear, and because the span of finished product or semi-finished product size specification is large, corresponding to flying shear, the shearing work pattern of each specification is also different.Rolling comparatively small dimension time, mill speed is very fast, and flying shear also need change the revolution of simple shear sword or the pivotal shearing work pattern of three cutting edges according to manufacturing technique requirent.The tool rest location and installation mode of the rotary shear pattern of flying shear is by securing dowel 2 screw, the inclined-plane of alignment pin 2 end and the main tooth case of flying shear are exported turn round the pin-and-hole cut on arm center to locate skewback 1, as shown in Figures 1 and 2, the form that inclined-plane is adjacent to completely to realize the location and installation of tool rest, as shown in Figure 3.
Owing to exporting revolution, to cut the pin-and-hole aperture on arm body larger than alignment pin 2 diameter of scissors tool rest, still there will be following problem aborning: 1) the every subnormal segmentation of flying shear or accident cataclasm, particularly cataclasm the produced shearing force of accident, all can cause huge impulsive force to the alignment pin 2 on scissors base.The impulsive force of this moment is far longer than the pretightning force of alignment pin 2 holding screw, causes tool rest alignment pin 2 to occur shifting phenomena thereupon, makes it realize effective location.Because alignment pin 2 occurs that displacement blade clearance becomes large thereupon, beyond normal operating range, just need be carried out shears blades space adjustment by forced-stopping machine, cause production cannot be continuous.2) when returning dress to next time after the knife adjustment of often pair of flying shear tool rest uses well one-period off-line, due to the position that tool rest alignment pin 2 cannot accurately find installed last time, make each flying shear change tool rest and all must readjust blade clearance, substantially prolongs the activity duration.
Utility model content
In order to overcome the above-mentioned shortcoming of prior art, the utility model provides a kind of bar combined type flying shear to cut arm positioning sleeve, and it can be eliminated scissors base alignment pin well and be subject to external force, and occurs the generation of displacement fault.Avoid adjusting because blade clearance becomes need shut down greatly, force production to carry out by normal continuous.Arm positioning sleeve cut by this bar combined type flying shear, can also ensure that the upper and lower tool rest of flying shear realizes effective location.When each change rotary shear mode of operation, alignment pin can guarantee that installation site is identical, avoid the work that repeatedly need adjust blade clearance because looking for position to be forbidden, greatly reduce the activity duration of changing shear mode, ensure that production continue carry out, this positioning sleeve also have install simple, locate the advantages such as reliable, non-maintaining.
The utility model solves the technical scheme that its technical problem adopts: arm positioning sleeve cut by a kind of bar combined type flying shear, comprise location skewback, an annular sleeve is studded with outside this skewback upper end, location, this location skewback with adopt between annular sleeve integrated be connected, be that alignment pin plays and leads and look for position to act on when can be fitted on the inclined-plane of locating skewback and alignment pin end face by this annular sleeve, by the pretightning force of alignment pin holding screw, two inclined-planes are adjacent to completely, alignment pin just can be made to realize effective location.
The beneficial effects of the utility model are: 1) can determine that flying shear is in the shearing work patterns such as the simple shear sword revolution changed needed for correspondence or three cutting edge revolutions, flying shear tool rest alignment pin and combined type flying shear cut arm positioning sleeve can bear flying shear normal segmentation or accident cataclasm in, the significant shear impulsive force produced, and main alignment pin can not be made to occur shifting phenomena.Ensure that flying shear blade well, through repeatedly shearing the phenomenon that all there will not be gap to become large, achieving the effective location of upper and lower flying shear tool rest, ensure that production continue carry out.2) when flying shear changes rotary shear mode of operation, cutting between arm positioning sleeve and alignment pin due to bar combined type flying shear is matched in clearance, during installation flying shear tool rest, alignment pin can find the installation site of a life cycle exactly, avoid and repeatedly adjust blade clearance, substantially reduce the activity duration that flying shear changes shearing work pattern.

In figure: 1-locates skewback, 2-alignment pin, 3-annular sleeve.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
See Fig. 3 ~ Fig. 6, arm positioning sleeve cut by a kind of bar combined type flying shear, comprise location skewback 1, an annular sleeve 3 is studded with outside this location skewback 1 upper end, integrated being connected is adopted between this location skewback 1 with annular sleeve 3, can be that alignment pin 2 plays and leads and look for position to act on when locating skewback 1 inclined-plane with alignment pin 2 end face and fitting by this annular sleeve 3, by the pretightning force of alignment pin 2 holding screw, two inclined-planes are adjacent to completely, alignment pin 2 just can be made to realize effective location.
The utility model has the following advantages: 1) can determine that flying shear is in the shearing work patterns such as the simple shear sword revolution changed needed for correspondence or three cutting edge revolutions, flying shear tool rest alignment pin 2 and combined type flying shear cut arm positioning sleeve can bear flying shear normal segmentation or accident cataclasm in, the significant shear impulsive force produced, and main alignment pin 2 can not be made to occur shifting phenomena.Ensure that flying shear blade well, through repeatedly shearing the phenomenon that all there will not be gap to become large, achieving the effective location of upper and lower flying shear tool rest, ensure that production continue carry out.2) when flying shear changes rotary shear mode of operation, cutting between arm positioning sleeve and alignment pin 2 due to bar combined type flying shear is matched in clearance, during installation flying shear tool rest, alignment pin 2 can find the installation site of a life cycle exactly, avoid and repeatedly adjust blade clearance, substantially reduce the activity duration that flying shear changes shearing work pattern.
