Abstract
The utility model discloses a stretcher is kept silent and is pressed from both sides material device, its including be used for centre gripping panel, lower clamp, go up clinch, all be fixed with the meniscus in the lower clamp, offer flutedly on the meniscus, the dovetail key lower part is placed in in the recess and with the meniscus pass through connecting bolt is connected fixed, the dovetail key with press from both sides the dovetail cooperation installation that tight clinohedral bottom surface central authorities seted up, the tight clinohedral of clamp can be followed the dovetail key slides, the dental lamina through the location compact heap be fixed in press from both sides tight clinohedral on, all adopt the inclined plane to be connected between dental lamina and location compact heap, dental lamina and the double -layered tight clinohedral. The utility model discloses can effectually prevent that aluminium bits from piling up, very big reduction clearance number of times also is favorable to avoiding the clamp with the friction of aluminium bits and produce the smooth phenomenon that hinders, improves productivity, avoids disconnected area to assault the damage that leads to the fact clamp and other devices.
Description
Technical field
The utility model belongs to stretching-machine technical field, more particularly, to a kind of stretcher jaw clamping device.
Background technology
Strip stretching-machine is one of key equipment of production Aero-Space high-performance sheet material, dedicated for aluminium and aluminium alloy plate
The tension straingtening technique of material, is stretched by being curved aligning and strength to sheet material, to eliminate the internal stress of sheet material, is improved straight
Degree, obtains high-quality, high performance pre-stretching aluminium sheet.Stretching-machine Levelling principle be the two ends for biting sheet metal using jaw simultaneously
Enough pulling force are imposed, makes sheet material produce plastic elongation deformation so as to which the uneven in length fibre length of draw direction tends to basic
After equal, stable state is returned to equal spring-go amount when laying down external force, reach the purpose of tension straingtening.Sheet material enters jaw
Afterwards, it is the necessary step of stretched operation by being stretched after jaw clamping, therefore, the reliability and continuation of clamping seem
It is particularly important.Traditional clamping device complex structure, manufacture difficulty is big, is difficult to change, and by long-term use easily in clamp
Groove piles up a large amount of aluminium skimmings, makes whole device lose the effect of clamping.
The content of the invention
To solve the above problems, the purpose of this utility model is to provide the good stretching-machine of a kind of simple structure, using effect
Jaw clamping device, it can effectively realize the clamping of sheet material.
For achieving the above object, the utility model is adopted the following technical scheme that：
A kind of stretcher jaw clamping device, it includes the upper and lower clamp for clamping sheet material, in upper clamp, lower clamp
Meniscus is respectively and fixedly provided with, opens up fluted on meniscus, dovetail key bottom is placed in the groove and with meniscus by being connected
Bolt connection is fixed, and the dovetail groove that dovetail key is opened up with clamping clinohedral bottom surface central authorities coordinates to be installed, and clamping clinohedral being capable of edge
The dovetail key slides；Dental lamina is fixed in clamping clinohedral by position housing piece, dental lamina and position housing piece, dental lamina and folder
Connected using inclined-plane between tight clinohedral.
Further, the clamping clinohedral rear end of above-mentioned upper clamp, lower clamp is provided with isolation damper.
Further, above-mentioned dental lamina is connected with position housing piece by the inclined-plane with seam.
Further, the angle between above-mentioned dental lamina and position housing piece is 10 °～20 °.
Further, the angle between above-mentioned dental lamina and clamping clinohedral is 10 °～20 °.
Because using technical scheme as above, the utility model has following superiority：
The stretcher jaw clamping device, its simple structure is easy to use, it is easy to dismounting and maintenance, is easy to manufacture to promote
Use, meniscus can effectively prevent aluminium skimmings from piling up with the version of dovetail key, greatly reduce clearing times, also favorably
Sliding resistance phenomenon is produced in avoiding clamp and aluminium skimmings friction, is raised labour productivity；Isolation damper can avoid broken belt from impacting
Clamp and the damage of other devices are caused, adopting inclined-plane to connect between dental lamina and position housing piece can be with less tools for bolts ' pretension
Power realizes larger thrust, effectively avoids position housing piece from receiving vibrations and produces and release phenomenon, dental lamina with clamp inclined-plane
The displacement of dental lamina can be effectively limited between body using inclined-plane connection, it is to avoid band clamps uneven.

Specific embodiment
Below in conjunction with the accompanying drawings the technical solution of the utility model is described in further detail with specific embodiment.
As shown in Figure 1, 2, the utility model stretcher jaw clamping device, it includes the upper and lower folder for clamping sheet material
Meniscus 2 is respectively and fixedly provided with pincers, upper clamp 1, lower clamp 5, meniscus is fixed on stretching-machine body, is offered on meniscus recessed
Groove 11, the bottom of dovetail key 10 is placed in the groove and is connected by connecting bolt 9 with meniscus, and dovetail key is oblique with clamping
The dovetail groove that the bottom surface central authorities of face body 8 open up coordinates to be installed, and clamping clinohedral can slide along the dovetail key；Dental lamina 4 is by fixed
Position compact heap 7 is fixed in clamping clinohedral and using by attachment screw fastening, dental lamina and position housing piece, dental lamina and clamping
Connected using inclined-plane between clinohedral.
Above-mentioned upper clamp 1, the clamping clinohedral rear end of lower clamp 5 are provided with isolation damper 6.
Above-mentioned dental lamina 4 is connected with position housing piece 7 by the inclined-plane with seam.
Angle between above-mentioned dental lamina 4 and position housing piece 7 is 10 °～20 °.
Above-mentioned dental lamina 4 and the angle clamped between clinohedral 8 are 10 °～20 °.
After sheet material reaches the position specified, hydraulic cylinder promotes upper clamp 1, the clamping clinohedral 8 of lower clamp 5 by push rod
Slide on dovetail key 10, the dental lamina for making upper clamp 1, lower clamp 5 clamps sheet material 3, realizes stretching sheet material then.
Preferred embodiment of the present utility model is the foregoing is only, rather than to restriction of the present utility model, without departing from this
In the case of the spirit and scope of utility model, all impartial changes made according to the utility model claim and modification,
All should belong within scope of patent protection of the present utility model.
