Description

A kind of bar cropper cutting off tool

Technical field

Steel bar processing machinery field is the utility model is related to, is specially a kind of bar cropper cutting off tool.

Background technology

Bar cropper is the conventional machinery equipment that reinforcing bar is fixed cut-out in steel bar meter process, including feeding platform, The parts such as reinforcing bar clamping piece, cutterhead, down-pressed pole, bar cutting process are carried out by cutoff tool, are divided into stationary knife disk and movable knife disc.Tradition The cutting off tool of bar cropper be square structure, during cut-out, by the pinch shock power pair between movable knife disc and stationary knife disk Reinforcing bar is cut off, but due to the diversity of bar types and specification used in actual life, movable knife disc is made when pushing Lower pressure is inconsistent, to cutterhead neither one buffer protection function during pushing, is easily made if lower pressure is excessive The damage of cutterhead is caused into being deformed upon between reinforcing bar and cutterhead, if lower pressure is too small, reinforcing bar is be easy to cause and is not easy to cut Break, or section is irregular, influences to use, for this it is proposed that a kind of bar cropper cutting off tool is above-mentioned for solving Problem.

The content of the invention

The purpose of this utility model is to provide a kind of bar cropper cutting off tool, to solve in above-mentioned background technology The problem of proposition.

To achieve the above object, the utility model provides following technical solution：A kind of bar cropper cutting off tool, bag Stationary knife disk and movable knife disc are included, the movable knife disc is located above stationary knife disk, and down-pressed pole, and movable knife disc are fixedly connected with the movable knife disc Lower end is equipped with some groups of cutting edges of different shapes, and the stationary knife disk correspondence position is equipped with the cutting groove of respective shapes and size Mouthful, the rear and front end activity of the movable knife disc is connected in sliding slot, and the sliding slot is fixed in cutting machine rack, and the movable knife disc is right Side upper end is fixed with pushing buffer stopper, and the pushing buffer stopper activity is plugged in the pushing dashpot of fixed block, under described Pressure dashpot bottom is fixedly connected by several buffer springs and pushes buffer stopper bottom, and the fixed block is fixed in rack.

Preferably, under the width of the sliding slot inner groovy and the thickness of movable knife disc are consistent, and the length of sliding slot is more than The width of the distance between the sum of the amount of feed of compression bar and the height of movable knife disc, two sliding slots and movable knife disc is consistent.

Preferably, the pushing buffer stopper is inverted L shape structure, and is divided into lateral blocks and vertical block, and the lateral blocks are fixed It is connected on the right flank of movable knife disc, the length of the vertical block is less than the depth for pushing dashpot.

Preferably, the quantity of the buffer spring is not less than two, and it is evenly distributed on and pushes buffer stopper and push slow Between jet-bedding.

Compared with prior art, the beneficial effects of the utility model are：The utility model structure using when reinforcing bar fixed On cut-out notch, drive movable knife disc to push by down-pressed pole, cutoff process, pushing or upper lift in movable knife disc are carried out to reinforcing bar During, movable knife disc all the time in sliding slot slide by both sides, ensures that movable knife disc does not shift in cutting-off process, makes cut-out more Stablize, and then protect movable knife disc, increase its service life, while make section more smooth, after bar cutting, due to moving knife Disk still has the inertia being pressed downward, and drives pushing buffer stopper to be moved downward in pushing dashpot, under the action of buffer spring Slow down the progress of this movement, so as to have the function that buffering, avoid the damage of movable knife disc.

Brief description of the drawings

Fig. 2 pushes buffering slot structure schematic diagram for the utility model.

In figure：1 stationary knife disk, 2 movable knife discs, 3 down-pressed poles, 4 cutting edges, 5 cut-out notches, 6 sliding slots, 7 push buffer stopper, 71 horizontal strokes Dashpot is pushed to block, 72 vertical blocks, 8 buffer springs, 9 fixed blocks, 10.

Embodiment

The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work All other embodiments obtained, shall fall within the protection scope of the present invention.

- 2 are please referred to Fig.1, the utility model provides a kind of technical solution：A kind of bar cropper cutting off tool, including Stationary knife disk 1 and movable knife disc 2, movable knife disc 2 are located at the top of stationary knife disk 1, down-pressed pole 3, and movable knife disc are fixedly connected with the movable knife disc 2 2 lower ends are equipped with some groups of cutting edges 4 of different shapes, and 1 correspondence position of stationary knife disk is equipped with the cutting groove of respective shapes and size Mouth 5, so that cutterhead adapts to a variety of different steel grades.

The rear and front end activity of movable knife disc 2 is connected in sliding slot 6, and sliding slot 6 is fixed in cutting machine rack, 6 indent of sliding slot The width of groove and the thickness of movable knife disc 2 are consistent, and the length of sliding slot 6 is more than the amount of feed of down-pressed pole 3 and the height of movable knife disc 2 The width of the sum of degree, the distance between two sliding slots 6 and movable knife disc 2 is consistent, pushing or upper lift process in movable knife disc 2 In, movable knife disc 2 all the time in sliding slot 6 slide by both sides, ensures that movable knife disc 2 does not shift in cutting-off process, makes cut-out more Stablize, and then protect movable knife disc 2, increase its service life, while make section more smooth.

The 2 right side upper end of movable knife disc, which is fixed with, pushes buffer stopper 7, pushes 7 activity of buffer stopper and is plugged under fixed block 9 Press in dashpot 10, pushing buffer stopper 7 is inverted L shape structure, and is divided into lateral blocks 71 and vertical block 72, and lateral blocks 71 are fixedly connected On the right flank of movable knife disc 2, the length of vertical block 72 is less than the depth for pushing dashpot 10, ensures in buffer spring 8 soon During close to compression limit, lateral blocks 71 and fixed block 9 contact, and avoid buffer spring 8 that non-reversible deformation occurs, and push dashpot 10 Bottom is fixedly connected by several buffer springs 8 and pushes 7 bottom of buffer stopper, and fixed block 9 is fixed in rack, buffer spring 8 Quantity be not less than two, and its be evenly distributed on push buffer stopper 7 and push dashpot 10 between.

Operation principle：The utility model structure using when reinforcing bar is fixed on cut-out notch, driven by down-pressed pole 3 dynamic Cutterhead 2 pushes, to reinforcing bar carry out cutoff process, during the pushing or upper lift of movable knife disc 2, movable knife disc 2 all the time both sides in cunning Slided in groove 6, ensure that movable knife disc 2 does not shift in cutting-off process, cut-out is more stablized, and then protect movable knife disc 2, Increase its service life, while make section more smooth, after bar cutting, due to movable knife disc 2 still have one be pressed downward it is used Property, drive push buffer stopper 7 push dashpot 10 move downward, slow down under the action of buffer spring 8 this movement into OK, so as to have the function that buffering, the damage of movable knife disc 2 is avoided.
