Description

Horizontal band sawing machine saw card is adjusted structure

Technical field

The utility model belongs to a kind of technical field of stable saw blade, particularly is meant a kind of stable horizontal band sawing machine saw card adjustment structure of saw blade that makes, to promote the efficient of sawing action.

Background technology

Press, horizontal band sawing machine is a kind of cutting tools, it mainly is to utilize the saw blade of continuous cycle rotation or back and forth start that workpiece is carried out horizontal sawing, under the stability of considering saw blade, general sawing feeding is to push workpiece to saw blade, so the pushing force of workpiece can directly have influence on the stability of saw blade; In other words, when saw blade is too loose, during workpiece pushing saw blade, saw blade is understood stressed and is rocked, and the not enough phenomenon of stability is arranged, and so not only can have influence on the precision of sawing, and possible coping saw blade folder is pulled in workpiece, and causes the problem of saw blade fracture, and then has influence on the efficient of sawing.Otherwise, when saw blade when too tight, then can cause saw blade to lack flexibility, so during workpiece pushing saw blade, saw blade is when stressed, coping saw blade shortage compliance is so it ruptures in sawing process easily;

Therefore, general horizontal band sawing machine before use, need to check earlier whether the elasticity of saw blade is suitable, but when band sawing machine is adjusted to certain elasticity, when pushing workpiece to saw blade as the operator, be subjected to the operator and push away the inconsistent and inconsistent influence of workpiece material of the power of pulling, saw blade is adjusted under the same elasticity, and can't be suitable for whole sawing process, so saw blade still can produce and rock, so saw blade if can be given suitable restriction in sawing process, can change in response to the variation of its pushing force and material simultaneously, then can make saw blade obtain suitable strain, not only can not have influence on the stability of sawing, also reason pine or too tight and rupture too not.

The utility model content

The purpose of this utility model is to provide a kind of horizontal band sawing machine saw card to adjust structure, can't suitably keep inconvenience and the puzzlement that stability is caused in its sawing process to solve existing horizontal band sawing machine, guaranteeing the steadiness of saw blade in sawing process, and can promote the cutting-rate and the security of horizontal band sawing machine.

For achieving the above object, the utility model mainly is by following technological means, comes aforesaid purpose of specific implementation and usefulness; Its casing by a tool workspace is constituted, and in the casing and be provided with a sawing saw blade that passes the workspace, and this saw blade is adjusted structure and is stretched at two side walls correspondence saw blade place, workspace, and it includes;

One pushing tow unit, it can push against the back of the body edge of saw blade, this pushing tow unit has a pedestal that can be locked on casing, the pedestal apical margin is formed with a chute, be provided with in the chute one can before and after the slide bar that slides, and pedestal is in the pull pressing plate of an alternative packing slide bar of end face lock, moreover have one on the pressing plate and adjust bolt, spiral shell is provided with a knob that can drive the forward and backward displacement of slide bar on this adjustment bolt, and this slide bar front end is provided with a wheel shaft that extends downwards again, and the wheel shaft bottom is provided with the roller of a corresponding saw blade back of the body edge;

One cramping unit, it can press from both sides the upper and lower surface of the saw blade of pulling, this cramping unit is to be slidingly equipped with an alternative upper guide plate and a bottom guide of adjusting height on pedestal, and upper and lower guide plate is adjusted the bolt lock by one respectively and is provided with a relative pressing plate that is positioned at saw blade top and below, is arranged with the trimming bolt that pressing plate can be shored in plural end on the upper and lower again guide plate.

Enforcement by the aforementioned techniques means, allow horizontal band resaw function of the present utility model adjust the roller of aforesaid ejection unit and the upper and lower compressing tablet of cramping unit according to elasticity, thickness and the working substance degree of exerting pressure of saw blade, can promote the stability of saw blade in sawing process effectively, so can have concurrently and promote cutting-rate and security, make horizontal band resaw function of the present utility model have more effect than known technology at aspects such as " saw blade stability, adjustment facility and flexibility and safety in utilization ".
