Description

Two knife clearance adjustment mechanism of cutter

Technical field

The utility model relates to a kind of two knife clearance adjustment mechanisms of cutter.

Background technique

Cutter mostly uses greatly hydraulic-driven, and security performance is reliable, easy to operate.Cutter is processed suitable for metal recovery Factory, abandoned car disassemble field, metallurgy and foundry industry, carry out cold conditions cutting, pressure to fashioned iron of various shapes and various metal materials Flange processed；Cutter common are Crocodile type cutter, planer-type cutter, horizontal shearing machine and punching (shearing) machine etc..Shearing Machine is not in use since hinged moving knife is stopped transport row, it may appear that the case where two knife gaps become larger, if not in time Adjustment will cause breaks down even whole cutter and scrap, and the mode in two knife gaps of adjustment is artificial at present, too time-consuming to take Power influences work efficiency.

Utility model content

The purpose of this utility model is that overcoming defect existing in the prior art, a kind of two knife gap of cutter is provided Adjustment mechanism, gives adjustment one adjustable spacing of bushing in initial installation, ingenious in design, structure is simple.

To achieve the above object, the technical solution of the utility model is to design a kind of two knife clearance adjustment mechanism of cutter, Adjustment bushing including being set in cutter main shaft one end, adjustment bushing are arranged close to cutter lower part stationary knife, cutter top Its blade side of the moving knife of setting is fixed on main shaft, is equipped with blind round hole in the middle part of adjustment bushing and blind bore end is against dynamic Knife setting, hole bottom wall are equipped with spacing with the spindle nose being arranged by it, adjust an end of blind bore end face on bushing Face is in disk and the outer diameter for having a diameter larger than blind hole, and the side of adjustment its disk shape end face of bushing is arranged two knife gaps and adjusts fastening Part, adjustment fastener are located remotely from the side setting of cutter stationary knife.

Further technical solution is that adjustment fastener is adjusting screw, and adjusting screw passes through adjustment its disk shape of bushing Threaded hole on end face is simultaneously threadedly coupled with cutter rack, and main axis is arranged in cutter rack, adjusts its disk of bushing Threaded hole on the shape end face of face is located on the end face beyond blind hole.Since hole bottom wall is equipped with the spindle nose being arranged by it Spacing, and blind bore end is arranged against moving knife when initial, therefore install initially tighten adjusting screw after realize each component and consolidate It is fixed firm, then after a period of use two knife gaps become larger (i.e. moving knife and adjustment its blind bore end of bushing become not against And have spacing), at this moment need to only tighten adjusting screw can be realized two knife gaps of adjustment (because hole bottom wall be arranged by it Spindle nose be equipped with spacing, and adjust its blind bore end of bushing fixed setting stationary knife), only when adjustment several times after hole bottom wall It can not just be had adjusted again after being abutted together with the spindle nose being arranged by it.It is ingenious in design, adjustment be easy it is quick and convenient, significantly In the working hour for saving two knife gaps of adjustment, improve work efficiency.

Further technical solution is that adjustment fastener is one piece of pressure plate against adjustment its disk shape end face of bushing, Pressure plate has also been wholely set connecting plate, the end of connecting plate be fixedly connected on moving knife its on the side of adjustment bushing.By In on the side that connecting plate is fixedly connected on moving knife, once so gap occur in moving knife and stationary knife, connecting plate is laterally moved with moving knife Dynamic, drive pressure plate in this way is mobile, so that adjustment bushing moves inward, to realize stationary knife to moving knife movement to adjust between two knives Gap realizes two knife gap of adjust automatically.

Further technical solution is that adjustment fastener is one piece and is fixed at the perpendicular of adjustment its disk shape end face of bushing To plate, a through-hole is set in vertical plate, is equipped with one end across through-hole and is resisted against the adjustment bar on moving knife side, adjust the another of bar One end is fixedly installed vertical abutment plate, its one end for being fixedly connected with spring on one side far from vertical plate of abutment plate, spring it is another One end is fixedly connected in fixed plate and spring is in impaction state, and fixed plate is fixedly linked with cutter rack.It is arranged in this way Worked normally when moving knife and stationary knife keep initial spacing, and when the spacing of moving knife and stationary knife becomes larger, adjustment bar be detached from against Moving knife side is then gone over by spring top at once, and adjustment bar is resisted against on moving knife again, while abutment plate is and then moved to moving knife direction It is dynamic, and drive adjustment bushing mobile to moving knife, realize two knife gap of adjust automatically.

Advantages and beneficial effects of the utility model lie in that giving adjustment bushing one adjustable in initial installation Away from directly tightening adjusting screw when so that needing to adjust in subsequent use process, ingenious in design, structure is simple or even energy Two knife gap of adjust automatically enough can be realized by the setting of different adjustment fasteners.It is arranged due to hole bottom wall and by it Spindle nose is equipped with spacing, and it is initial when blind bore end be arranged against moving knife, therefore install initially tighten adjusting screw after i.e. in fact Showed each component fix stably, then after a period of use two knife gaps become larger (i.e. moving knife and adjustment its blind bore end of bushing Become not against and have spacing), at this moment need to only tighten adjusting screw can be realized two knife gaps of adjustment (because of hole bottom wall Spacing is equipped with the spindle nose that is arranged by it), hole bottom wall and the spindle nose being arranged by it only after adjustment several times It can not just be had adjusted again after being abutted together.Ingenious in design, adjustment is easy quick and convenient, and two knife gaps of adjustment are greatly saved Working hour improves work efficiency.Since connecting plate is fixedly connected on the side of moving knife, once so gap occur in moving knife and stationary knife, Connecting plate is laterally mobile with moving knife, and drive pressure plate in this way is mobile, so that adjustment bushing moves inward, to realize stationary knife to moving knife Movement realizes two knife gap of adjust automatically to adjust two knife gaps.It is worked normally when moving knife keeps initial spacing with stationary knife, And when the spacing of moving knife and stationary knife becomes larger, adjustment bar is detached from against moving knife side, then is gone at once by spring top, and adjustment bar is again It is resisted against on moving knife, while abutment plate is and then mobile to moving knife direction, and drives adjustment bushing mobile to moving knife, realize automatic adjust Whole two knife gap.
