Description
Technical field
The present invention relates to bender lower die to have pneumatic technique for fixing field, specifically pneumatic pinch workbench and bending
Machine.
Background technology
Bender will choose suitable upper and lower mould in metal plate bending production according to the size of product bending angle, thickness
Tool, and Bending Mould is the instrument that bender is used for processing and forming plate, its main changing by institute's moulding material physical state
Become to realize the processing of article profile, to make blank turn into the system for having given shape and size in the presence of bender pressure
The instrument of part.Bending machine die is generally divided into upper die of bending machine and lower mould, is the mould for sheet metal forming and separation.
Same bender can support the use different Bending Moulds to process, and therefore, shop worker can be frequent
The mode manually clamped changes the action of upper/lower die, and the mould after replacing must have position reference, required precision ratio
It is higher, because this is directly connected to the dimensional accuracy after metal plate product bending, when whole Renewal process gets off to take substantial amounts of
Between and energy, therefore this problem is directed to, such as patent 201710275359.3, entitled " clamping block unit and bender ", the device
The technical scheme used for：Including fixed part, clamping part and move portion；Inlet chamber and and inlet chamber are provided with fixed part
The air inlet of connection；Slided in inlet chamber and be provided with move portion；Move portion is fixedly connected with clamping part；Air inlet is used for and outside
Air supply system connects；It is used to place mould between clamping part and fixed part；Fixed part is used for the upper beam for being fixed on bender；When
Outside air supply system is passed through gas into inlet chamber, and gas can promote move portion to move, to drive clamping part to be moved to fixed part
Dynamic, by mold cramping, compared with traditional hand-operated clamping mode, automaticity is high, saves manpower and time, improves life
Efficiency is produced, suitable for the situation of whole segment length's mold cramping, but there is a problem in that：The patent is by outside air supply system
It is passed through gas into inlet chamber, the movement of gas push move portion realizes the clamping of mould to drive clamping part to be moved to fixed part,
Complex structural designs, amount of parts, species are more, installing/dismounting trouble, and cost is high.
The content of the invention
The technical assignment of the present invention is the deficiency for more than, there is provided pneumatic pinch workbench and bender, the device can
Solve complex structural designs in the prior art, amount of parts, species are more, installing/dismounting trouble, and cost is high asks
Topic.
The technical solution adopted for the present invention to solve the technical problems is：
Pneumatic pinch workbench, including workbench, in addition to fixture block, ball screw, tracheae, magnetic valve and compressed air source unit；Folder
Block is locked on workbench by multiple ball screws；One end setting of fixture block is fluted, and tracheae is arranged on recessed through groove
In groove；One end of tracheae is sequentially connected magnetic valve and compressed air source unit, and the other end is fixed on the both sides of workbench with silently blocking；
Tracheae, magnetic valve, compressed air source unit and silently form loop.
The upper end top circumference direction of ball screw is the ball screw of spherical structure.
Fixture block is arranged on ball screw, and fixture block can surround ball screw and rotate.
The cross sectional shape of fixture block is falculate fixture block.
The perforate of groove is the groove of cuboid or cylindrical structure.
Bender, mould is installed on bender, mould includes mold and lower mould；Also include pneumatic pinch to work
Platform, pneumatic pinch workbench are any pneumatic pinch workbench in above-mentioned；Lower mould is located at the top of workbench, and two
Person contacts connection；Fixture block is located at the side of lower mould.
Fixture block unclamps lower mould, and fixture block upper end and the angle between the lower mold outer surface of fixture block side are not less than
1.97 degree.
Fixture block clamps lower mould, and fixture block upper end and the angle between the lower mold outer surface of fixture block side are not less than
0.54 degree.
Compared to the prior art the pneumatic pinch workbench and bender of the present invention, has the advantages that：
1st, fixture block is locked on workbench by multiple ball screws, and the upper end top circumference direction of ball screw is sphere knot
The ball screw of structure, fixture block are arranged on ball screw, it can be ensured that fixture block can be free in the state of locking for ball screw
Rotation；
2nd, one end of fixture block is set fluted, and tracheae is arranged in groove through groove；One end of tracheae is sequentially connected magnetic valve
And compressed air source unit, the other end are fixed on the both sides of workbench with silently blocking；In use, magnetic valve receives electric signal, gas
Source device supplies for tracheae, after tracheae expansion, can push up fixture block lower end and open certain angle, meanwhile, fixture block upper end can rotate
Same angle, fixture block upper end produce extruding force with lower mould, realize that fixture block clamps the effect of lower mould；It is and swollen using tracheae
Swollen or contraction change makes fixture block clamp or unclamp lower mould, has and uses the advantages of simple, easy for installation；
3rd, when fixture block clamps lower mould, fixture block upper end and the angle between the lower mold outer surface of fixture block side are not less than
0.54 degree, the installation fixed precision of lower mould is advantageously ensured that, ensures the accuracy of position reference, fixture block is improved and clamps lower mould
The job stability of tool；
4th, device has the advantages of structure design is simple, and amount of parts, species are few, and installing/dismounting is simple, and cost is low,
Therefore, have good value for applications.
