It closes, realizes the shearing of strip.
Different from it is existing it is double acting cut device, as shown in figure 4, the double acting device of cutting of the utility model is provided with blade clearance
Structure is adjusted, the shears blades space adjustment structure includes tool apron and tool apron pressing plate, and the tool apron pressing plate is connected on knife rest, described
Tool apron pressing plate is withheld in having the gap that tool apron can be made free to slide, the adjustment direction of the tool apron on tool apron and between tool apron
It is upper that there is activity space, guarantee that tool apron can move, the adjustment of blade clearance is realized, in order to guarantee that tool apron has adjustable activity
Space, can be tool apron pressing plate can also be arranged as shown in Fig. 2, gap is arranged between tool apron adjustment direction and tool apron pressing plate
In the both ends of tool apron, tool apron will be moved, then tool apron pressing plate cannot compress tool apron completely, in order to adjust between tool apron and tool apron pressing plate
Gap in the height direction, as shown in figure 3, being provided with adjustment gasket 16 between the tool apron pressing plate and knife rest.
The tool apron has adjustment inclined-plane in the side of its adjustment direction and is provided with the inclined wedge matched with adjustment inclined-plane
Block 21, the tapered wedges 21 are connected with driving wedge block 21 along the power mechanism of adjustment inclined-plane sliding, and the tool apron connection is useful
In the hold-down mechanism for making tool apron be close to tapered wedges 21.
Theoretically speaking shears blades space adjustment structure can be set on movable upper tool post 7, control upper scissor blade 18 is mobile,
It can be set on movable lower slide 3, control lower scissor blade 19 is mobile, is able to achieve the adjustment of blade clearance.But to improving
Stability, shears blades space adjustment structure are preferably disposed on movable lower slide 3.
By taking Fig. 4 illustrated embodiment as an example, shears blades space adjustment structure is set on movable lower slide 3, adjustment knot
Tool apron described in structure is lower tool apron 20, and the tool apron pressing plate is lower tool apron pressing plate 15.When needing to adjust blade clearance, benefit
The transverse shifting to the left of tapered wedges 21 is pushed with power mechanism, under the interaction on the adjustment inclined-plane and tapered wedges 21 of tool apron, is compeled
Make tool apron to longitudinal movement above paper, the gap between upper scissor blade 18 and lower scissor blade 19 becomes smaller；It is pushed using power mechanism oblique
, there is gap between the adjustment inclined-plane and tapered wedges 21 of tool apron in the transverse shifting to the right of voussoir 21, under the action of hold-down mechanism,
To longitudinal movement below paper, the gap between upper scissor blade 18 and lower scissor blade 19 becomes larger tool apron, so can be quickly and easily real
The now upper double acting shears blades space adjustment for cutting device.
Hold-down mechanism can be spring, cylinder etc., as long as tool apron can be made mutually to be close to tapered wedges 21.Such as Fig. 4
Shown in embodiment, the hold-down mechanism includes fixed baffle 22, connection bolt 24 and butterfly spring 23, the fixed baffle
22 are located at tapered wedges 21 backwards to the side of tool apron, are connected with each other between the fixed baffle 22 and tool apron by connection bolt 24,
The butterfly spring 23 is set between connection bolt 24 and fixed baffle 22, and the tapered wedges 21 are provided with abdicating through hole 32,

25 are installed in bearing, and handwheel 25 is threadedly coupled with screw rod 26, and the rotation of handwheel 25 moves along its axis screw rod 26, drive oblique
21 transverse shifting of voussoir, and then realize the adjustment of blade clearance.
It, can moving distance by tapered wedges 21 and its angle since blade clearance is adjusted by tapered wedges 21
Degree calculates the adjustment distance of blade clearance, on this basis, observes the adjustment situation of blade clearance, the handwheel for convenience
Dial 27 is provided on 25, be provided on the knife rest with matched first pointer 28 of dial 27, set on the screw rod 26
It is equipped with the second pointer 31, the position of corresponding second pointer 31 is provided with graduated scale 29 on the knife rest.Dial 27 and first refers to
Needle 28 can reflect the changing value of blade clearance, and graduated scale 29 and the second pointer 31 can reflect the total backlash of lower scissor blade 19.
When shears blades space adjustment in place after just need to lock position, prevent it from changing, although screw thread has
Certain self-locking effect, but ensured to improve, the locking mechanism for located hand wheel 25 is provided on the handwheel 25.Lock
Determining mechanism can be using mechanical stop, clamping device etc., is able to achieve the positioning of handwheel 25, prevents handwheel 25 in improper behaviour
Make lower rotation, leads to the variation of blade clearance, to guarantee the reliability of the device.
Due to the double acting wider width for cutting device, two sides influence double acting to cut dress it is possible that nonsynchronous problem
The reliability and service life set, in order to guarantee that double acting device two sides of cutting are synchronous, the connecting rod of the rack two sides is that band tooth connects
It bar 5 and is respectively cooperating with and is provided with synchromesh gear 17, the synchromesh gear 17 positioned at rack two sides passes through synchronizing shaft and is connected with each other.It is logical
Synchromesh gear 17 and synchronizing shaft are crossed, moves synchronously the band tooth connecting rod 5 of two sides, to ensure that the double acting synchronization for cutting device two sides
Property.
During shear steel band, pressing plate can be set and compress strip, to improve the stabilization of shearing, as shown in Figure 2
In embodiment, it is provided with top board 11 on the activity upper tool post 7, is correspondingly arranged on lower platen 12 on the activity lower slide 3,
Guide rod 14 is provided on the activity lower slide 3, the guide rod 14 is slidably matched with movable lower slide 3, the lower platen
12 are set on guide rod 14, be arranged with compressed spring 13 outside the guide rod 14 and compressed spring 13 be located at lower platen 12 and
Between movable lower slide 3.
The setting of compressed spring 13 and guide rod 14 allows lower platen 12 movable, reaches low level in movable upper tool post 7
Afterwards, shearing power mechanism continues to extend, and lower platen 12 first clamps strip with top board 11, with movable lower slide 3 into
One step rises, and compressed spring 13 is shunk, and lower platen 12 clamps strip with top board 11, and then lower scissor blade 19 rises to shearing position
It sets to interact with upper scissor blade 18 and realizes strip shearing.
