Description

Upper and lower cutting-type cutting knife

Technical field

Cutting apparatus field is the utility model is related to, especially upper and lower cutting-type cutting knife.

Background technology

The edge of a knife up and down of existing cutting knife does not have guider, so cutting, stability is poor, and cutter gap can not ensure, It is big to cut burr.And it is complicated, cutter life is low, easy crushing knife.

Utility model content

The technical problems to be solved in the utility model is：Poor in order to solve existing cutting knife stability, it is big to cut burr, Complicated and short life deficiency.The utility model provides a kind of cutting-type cutting knife up and down, passes through guider Upper and lower knife does not depart from structure, and stability is high, cuts precisely, and service life is grown.

Technical solution is used by the utility model solves its technical problem：

A kind of cutting-type cutting knife, including lower knife, upper cutting die, buffer unit, spring, upper slitter and binder block up and down, binder Block both ends of the surface are fixedly connected with upper slitter, and binder block is slidably connected with lower knife, and the end face of lower knife is equipped with groove, the groove two of lower knife Side is cutting edge, and the top of upper slitter is equipped with spring, and upper slitter passes through upper cutting die with binder block.

Through the above technical solutions, binder block both ends are equipped with slide bar, lower knife both ends are equipped with sliding slot, and slide bar is rectangular shaft, sliding Groove is placed in slide opening and is slidably connected with the matched rectangular opening of slide bar, slide bar.The cutting edge of lower knife is opposite with the cutting edge of upper slitter.On Cutting die drives the buffer unit at its both ends to be pushed to the runner float plate for being loaded with sheet stock.

Specifically, the upper slitter is bolted in the vertical side face of holding pad, and the cutting edge of upper slitter is towards lower knife.

Through the above technical solutions, the tow sides of holding pad are all fixed with upper slitter.

Specifically, the buffer unit is preferably polyurethane buffering block.

Through the above technical solutions, polyurethane possesses elasticity and frictional force, can be very good to press float plate.

Specifically, the lower knife bottom is equipped with lower edge bearing block.

Through the above technical solutions, lower edge bearing block helps lower knife to be fixed in rack.

Specifically, the end face of the binder block is equipped with positioning PIN, and lower knife end face is equipped with matched with positioning PIN Location hole.

Through the above technical solutions, when binder block moves down, positioning PIN can penetrate into perforation and lower knife on sheet stock Location hole in so that sheet stock can be accurately positioned, and help the opening and closing movement between upper slitter and lower knife to keep stablizing.

The beneficial effects of the utility model are：The utility model provides a kind of cutting-type cutting knife up and down, passes through guiding Device make it that knife does not depart from structure up and down, and stability is high, cuts precisely, and service life is grown.

Brief description of the drawings

The utility model is further illustrated with reference to the accompanying drawings and examples.

Fig. 1 is the structure diagram of the utility model；

Fig. 2 is that the utility model departs from the structure diagram after upper cutting die；

1. times knives in figure, cutting die on 2., 3. buffer units, 4. springs, 5. upper slitters, 6. binder blocks, 7. times edge bearing blocks, 8. is fixed Position PIN, 9. location holes.

Embodiment

The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram, Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows the composition related with the utility model.

Fig. 1 is the structure diagram of the utility model, and Fig. 2 is that the utility model departs from the structure diagram after upper cutting die.

A kind of cutting-type cutting knife, including lower knife 1, upper cutting die 2, buffer unit 3, spring 4, upper slitter 5 and binder block up and down 6,6 both ends of the surface of binder block are fixedly connected with upper slitter 5, and binder block 6 is slidably connected with lower knife 1, and the end face of lower knife 1 is equipped with groove, The groove both sides of lower knife 1 are cutting edge, and the top of upper slitter 5 is equipped with spring 4, and upper slitter 5 passes through upper cutting die 2 with binder block 6.The upper slitter 5 are bolted in the vertical side face of holding pad 6, and the cutting edge of upper slitter 5 is towards lower knife 1.The buffer unit 3 is preferably polyurethane Buffer stopper.The lower knife bottom is equipped with lower edge bearing block 7.The end face of the binder block 6, which is equipped with, positions PIN8, on lower 1 end face of knife Equipped with positioning the matched location holes 9 of PIN8.

With reference to shown in attached drawing 1 and attached drawing 2, hardware sheet stock is sent between upper slitter 5 and lower knife 1 and cuts position, cuts cylinder Push, cutting die 2 is down in driving.The buffer unit 3 of upper slitter 5, stop pushing block and polyurethane synchronously moves downward at this time.And delay Flushing device 3 can touch sheet stock runner float plate first, promote spring-compressed below, and at this moment sheet stock can follow downwards, until The cutting edge for cutting part patch and arriving lower knife 1 together of sheet stock.The retraction of spring 4 of last upper slitter 5 compresses sheet stock, until upper slitter 5 is and then pressed Material block 6 glides, and until the edge contacts of the cutting edge and lower knife 1 of upper slitter 5, forms shearing force, cuts off the product connected on sheet stock.

Using the above-mentioned desirable embodiment according to the utility model as enlightenment, pass through above-mentioned description, related work people Member can carry out various changes and amendments in the range of without departing from this item utility model technological thought completely.This item is real The content being not limited to new technical scope on specification, it is necessary to which its technology is determined according to right Property scope.
