Scissor material is pneumatic shearing device
Technical field
The utility model relates to a kind of frock clamp, relates in particular to a kind of being applicable to and breaks away from manual operations, and the scissor material that cuts off plastic products material handle is pneumatic shearing device.
Background technology
At present, moulding processing prune material the time, usually by manually directly utilizing step pliers, end cutter nippers to go to cut off, there is the defective that efficient is low, dangerous, labor strength is high and the instrument waste is serious in this trim mode of manual cut-out that relies on, can bring again much and scratch the quality problems of bringing by pruning sum of errors.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides the dangerous and accurate positioning simultaneously that injures finger etc. that a kind of eliminating causes by cut-out portion, cut off and be swift in motion, course of work safety, can regulate shearing lengths, and the scissor material that reaches the raising product percent of pass is pneumatic shearing device by different requirement are convenient.
The technical scheme that the utility model is taked to achieve these goals is: a kind of scissor material is pneumatic shearing device; comprise the cutting nippers cylinder; floor push; it is characterized in that: also comprise big base plate; platter; fixed head; fixing backing plate; locating piece; the protection thick stick; cutter hub; support column; axle sleeve; described cutter hub is fixed in an end inboard of cutting nippers cylinder by axle sleeve with screw; floor push is connected with the other end of cutting nippers cylinder; the cutting nippers cylinder is arranged on the big base plate; pass through two groups of fixed heads with screw; fixedly backing plate is connected with big base plate; locating piece and protection thick stick are screwed on platter, and platter and four support columns place on the big base plate.
Described cutter hub is made up of two tool arms, and the tool arm top is respectively equipped with the edge of a knife, and the edge of a knife arm inboard of a tool arm is provided with limited post, two tool arm handle end inboards are respectively equipped with groove, spring places in the groove, and same position is respectively equipped with locating hole in the middle of the tool arm, connects with axle sleeve; The end face of described locating piece is provided with a garden connected in star.
The beneficial effects of the utility model are, can be widely used in the removing of various injection moulding processing back part material handle, especially the material of part inside is removing, have accurately and put in place, cut-out is swift in motion, the production efficiency height, the yield rate height, course of work safety, economy, long service life are convenient to the characteristics safeguarding and change, and can be reached the purpose that significantly improves product percent of pass.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified:
Shown in Fig. 1,2,3,4,5,6, fixed head 3 and fixedly backing plate 4 by screw cutting nippers cylinder 10 is fixed on the big base plate, this connection can be adopted alternate manner, as with fixed head 3 and fixing backing plate 4 processing all-in-one-pieces, by screw cutting nippers cylinder 10 is fixed on the big base plate again.Four support columns 14 are screwed on big four jiaos of symmetric positions of base plate, and support column 14 also can be replaced by gripper shoe in addition.With the access interface of external source of the gas access floor push 16, the output port of floor push 16 inserts cutting nippers cylinders 10 by tracheae 15.During use; the part internal orifice that operating personnel will need earlier to shear the material handle is inserted in and is close on the locating piece 5; floor push 16 tramps with one's feet; connect external source of the gas, the piston reach in the cutting nippers cylinder 10 compresses the handle end of tool arm 8 and tool arm 9, makes the edge of a knife 17 closures; to expect cutting off; expect to fall between the slit of locating piece 5 and protection thick stick 6 being cut off the effect of back owing to gravity, the spring of establishing in the handle end of tool arm 8 and tool arm 9 is compressed at this moment.When unclamping floor push 16, disconnected external source of the gas at once, the piston in the cutting nippers cylinder 10 is return original position, and the handle end of tool arm 8 and tool arm 9 is opened under the effect of recoil of spring power, and the edge of a knife 17 also is opened simultaneously, finishes cutting-off process, takes off part and gets final product.
The rigid contact that the inboard limited post 13 that is provided with of the edge of a knife arm of tool arm 8 can alleviate two edges of a knife 17, the service life of the prolongation edge of a knife 17.The position dimension of locating piece 5, cutter hub 7 and length are that the size according to part gets, and are to guarantee to cut off material the significant dimensions that does not injure part again.The groove 5-1 of the operative end surface setting of locating piece 5 is that the shape according to part material handle is provided with, and it can be half garden groove, also can be the groove of right angle groove or other shape.Protection thick stick 6 is special set for safety operation, avoids pointing and the contacting of cutter hub, and prevents to injure in operation operating personnel's finger.The use that has made things convenient for the operator that is provided with owing to floor push 16.
