It can be arranged consistent.In other embodiments, the size and shape of left and right cutter (210,220) may also set up difference, as long as full
The cutter that the above-mentioned shearing work of foot requires.Cutter glass hard steel can be used in the material of above-mentioned left and right cutter (210,220)
Material.
In one embodiment, driving mechanism may include left cylinder 301 and right cylinder 302, respectively with the knife of left cutter 210
Tail is connected with the knife tail of right cutter 220.Left and right cylinder (301,302) can be fixedly mounted on ontology 100.Left and right cylinder
(301,302) it is used to respectively drive left cutter 210 and right cutter 220 in opposite directions or backwards to movement.The left and right cylinder (301,302)
It can be common commercial product.In other embodiments, driving mechanism can be other common driving machines such as motor, motor
Structure.
In one embodiment, above-mentioned shear may also include connector 400, the knife tail of left and right cutter (210,220)
It is connect with driving mechanism by the connector 400.Cutter can be fixed by common fastener with link block.Connector 400 can
To match the link block of knife tail shape, the shape of the link block can be any of the knife tail that plate shaped, U-shaped etc. is capable of fixed cutting tool
Shape.
In yet another embodiment, as shown in figure 3, further including limit base 500, the movement for constraining toolbox 200
Direction, limit base 500 are equipped with open slot 501 and the first passage and second channel that are oppositely arranged, left and right cutter (210,
220) cutter head can be each passed through first passage and second channel, and can converge in open slot 501.The open slot 501
Be equivalent to an observation panel, by the open slot 501 can clear view to the cutter head situation of left and right cutter (210,220), and can
According to the observation as a result, being adjusted accordingly to cutter.For the ease of assembling and processing, it is preferable that limit base 500 can be integrated
Formula structure, left and right cutter (210,220) opposite both sides can be inserted into limit base 500 respectively.In other embodiments, it limits
Seat 500 can be split structure, that is, be set as left limit seat and right limit seat；Left and right cutter (210,220) corresponds to respectively at this time
Opposite insertion left limit seat and right limit seat, adjust left and right cutter by adjusting height and the position of left and right limit base
The cutter head position and the direction of motion of (210,220) so that left and right cutter (210,220) disclosure satisfy that the processing item of shearing work
Part.
The first passage and second channel can allow for left and right cutter (210,220) to do small reciprocating motion in the channel,
To carry out the shearing work to guide pin silk.The first passage and second channel can be square duct or circular channel or its
The channel of his shape.Preferably, which can match with corresponding cutter shape.First passage and second channel can be respectively provided with
At 500 middle part of limit base, to form through-hole structure channel.In addition, first passage and second channel can also be arranged at limit base
500 bottom, to form the channel of groove structure.
When driving mechanism drives left cutter 210 and right cutter 220 to do reciprocal fortune at first passage and second channel respectively
When dynamic, the line on the cutter head vertex of left and right cutter (210,220) is on same straight line.It can guarantee left and right cutter in this way
(210,220) are moved each along shear direction, can be reduced left and right cutter (210,220) direction of motion and be occurred to deviate and lead to nothing
Method smoothly flattens the problem of guide rod silk.Further, since the cutter head of left and right cutter (210,220) is oppositely arranged, in order to avoid cutter head
Contact and damage, when moving toward one another, cutter head cannot contact left and right cutter (210,220), the cutter head vertex of left cutter 210 with
Minimum spacing d between the cutter head vertex of right cutter 220 meets 0.01mm≤d≤0.03mm.In one embodiment, between minimum
It is about 0.02mm away from d.In other embodiments, minimum spacing can be other numerical value in above range.
In another embodiment, as shown in figure 4, shear may also include jig 600, jig 600 is arranged in ontology
On 100 and it is placed in 500 lower section of limit base, for placing workpiece to be processed, jig 600 can be actuated to move up and down.It controls
On tool 600 driving element can be commonly used by setting cylinder, motor etc. to control the up and down motion of jig 600.Left and right cutter
It after (210,220) are pinched guide rod silk, can be broken under minimum external force, can be realized at this time by controlling 600 downlink of jig
The fast automatic of guide rod silk is blocked, and the degree of automation of shear is further increased.Specifically, when left and right cylinder (301,
302) after air inlet, cutter closing movement to the position of guide pin silk, by guide pin silk to easily broken degree, when 600 downlink of jig, is automatic
It blocks.It should be noted that in addition to this, can also be moved upward to block automatically after realizing shearing by controlling guide pin silk.
In one embodiment, the first opening 502 can be offered in the bottom of open slot 501,502 setting of the first opening exists
Lower position at the cutter head convergence of left and right cutter (210,220).Workpiece to be welded can be placed under first opening 502
Jig 600, the guide pin situation on workpiece on jig 600 can be directly observed by the first opening 502 opened up；And it waits cutting
After the completion of cutting is made, it can be taken out workpiece below shear by moving 600 downlink of jig, avoid taking from top
Expect and interfere shear and the guide pin silk of top, more conducively practical operation.
Each technical characteristic of embodiment described above can be combined arbitrarily, to keep description succinct, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, it is all considered to be the range of this specification record.
Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed,
But therefore it can not be interpreted as the limitation to utility model patent range.It should be pointed out that for the common skill of this field
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
