Description

A kind of two-way cutter mechanism

Technical field

The utility model relates to the coiling machine field, refers in particular to a kind of two-way cutter mechanism.

Background technology

Traditional spring cutter mechanism is digital control system control motor, and the gear-box of three grades of decelerations of driven by motor slowly runs bent axle, by crank guide rod mechanism, the slide block that is installed in the Cutter apron is moved again, and the slipper push cutting knife realizes cutting off the purpose of steel wire; For same machine, when processing left-handed spring and dextrorotation spring, because steel wire all is from the same side feeding, will cut off steel wires from two different directions up and down, need the such cutting-off tool system of two covers, this design shortcoming is complex structure, cost of manufacture is high, needs to improve.

Therefore, the inventor makes further research this, develops a kind of two-way cutter mechanism, and this case produces thus.

The utility model content

The purpose of this utility model is to provide a kind of two-way cutter mechanism, realized one the cover cutter mechanism can process left-handed spring or dextrorotation spring.

To achieve these goals, the technical solution of the utility model is as follows:

A kind of two-way cutter mechanism comprises cutting knife, Cutter apron, and slide block, slide, the core cutter, the core tool rest, described cutting knife comprises upper cutter and lower cutter, described Cutter apron comprises upper cutter seat and incision tool rest; Wherein upper cutter is arranged on the upper cutter seat, and the upper cutter seat is installed on the slide block, and is same, lower cutter is arranged on the incision tool rest, incision tool rest peace also is contained on the slide block, and slide block slidably is arranged in the slide, and the blade of upper cutter and lower cutter arranges in opposite directions; Described core cutter is between the blade of upper cutter and lower cutter, and the core cutter is installed on the core tool rest.

Further, be provided with set screw on the described Cutter apron, an end of set screw is conflicted on cutting knife.

Further, described upper cutter seat is provided with two set screw, and described incision tool rest also is provided with two set screw.

Further, the bottom surface of described incision tool rest also is provided with the stake of incision tool rest.

Further, also be provided with the cutting knife pad between described cutting knife and the slide block, the contact-making surface of cutting knife pad and cutting knife is arc.

After adopting such scheme, the utility model compared with prior art has the following advantages:

1. the cutting knife of cutting dextrorotation spring and left-handed spring is integral by slider designs, has greatly saved manufacturing cost.

2. the cutting knife back side is provided with the cutting knife pad of arc, is provided with set screw on the Cutter apron, can regulate cutting knife with respect to distance and the angle of slide block.

Description of drawings

Fig. 1 is schematic diagram of the present utility model;

Fig. 2 is the left view of Fig. 1.

Label declaration

Slide 1, slide block 11, upper cutter seat 2, upper cutter 21, incision tool rest 3, lower cutter 31, incision tool rest stake 32, core tool rest 4, core cutter 41, set screw 5, cutting knife pad 6, spring 7.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is further described.

As shown in the figure, a kind of two-way cutter mechanism that the utility model discloses comprises cutting knife, Cutter apron, and slide block 11, slide 1, core cutter 41, core tool rest 4, described cutting knife comprise upper cutter 21 and lower cutter 31, described Cutter apron comprises upper cutter seat 2 and incision tool rest 3; Wherein upper cutter 21 is arranged on the upper cutter seat 2, upper cutter seat 2 is installed on the slide block 11, same, lower cutter 31 is arranged on the incision tool rest 3, incision tool rest 3 peaces also are contained on the slide block 11, be that upper cutter seat 2 and incision tool rest 3 all are arranged on the same slide block 11, slide block 11 slidably is installed in the slide 1, and the blade of upper cutter 21 and lower cutter 31 arranges in opposite directions; Described core cutter 41 is between the blade of upper cutter 21 and lower cutter 31, and core cutter 41 is installed on the core tool rest 4, and the bottom surface of incision tool rest 3 also is provided with incision tool rest stake 32, is used for supporting lower cutter 31.

Respectively be provided with two set screw 5 on upper cutter seat 2 and the incision tool rest 3, an end of set screw 5 is conflicted on cutting knife; Also be provided with cutting knife pad 6 between cutting knife and the slide block 11, cutting knife pad 6 is arc with the contact-making surface of cutting knife, and when turning set screw 5, set screw 5 promotes cutting knife, can regulate cutting knife with respect to distance and the angle of slide block 11.

Operation principle of the present utility model is:

When coiling machine need to cut off the dextrorotation spring, regulate core tool rest 4 near upper cutter seat 2, thereby so that core cutter 41 close upper cutters 21, steel wire enters beginning dextrorotation from core cutter 41 upsides, when the length of spring arrives preseting length, under the effect of actuating unit, slide block 11 moves down in slide 1, and drive upper cutter seat 2 and move down, thereby so that upper cutter 21 cuts off the dextrorotation spring, cut off spring rear slider 11 and upwards reset, enter the circulation of next round.Because this moment, core cutter 41 was near upper cutter 21, so the lower cutter 31 that slide block 11 drives can't have influence on spring.

In like manner, when coiling machine need to cut off left-handed spring, regulate core tool rest 4 near incision tool rest 3, thereby so that core cutter 41 close lower cutters 31, it is left-handed that steel wire enters beginning from the downside of core cutter 41, when the length of spring arrived preseting length, under the effect of actuating unit, slide block 11 moved up in slide 1, driving incision tool rest 3 moves up, thereby so that lower cutter 31 cuts off left-handed spring, cut off spring rear slider 11 and reset downwards, enter the circulation of next round.Because this moment, core cutter 41 was near lower cutter 31, so the upper cutter 21 that slide block 11 drives can not have influence on spring yet.

By such scheme, realized that a cover cutter mechanism cuts off the purpose of two kinds of different springs, simple in structure, reduced the shared space of cost and machine.

Above-mentioned only is specific embodiment of the utility model, but design concept of the present utility model is not limited to this, allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
