The lifting device of fine blanking press slide block
Technical field
The utility model relates to a kind of press machine, particularly a kind of improvement of fine blanking press.
Background technology
In the prior art, fine blanking press also has quick-lift attachreactor, the action that also can provide lathe to produce fast rise when the back work stroke, descend fast.But all do not have the foreign matter measuring ability, like this, be difficult to guarantee the safe in utilization of mould and lathe that reliability reduces greatly.
The utility model content
The purpose of this utility model provide a kind of at hydraulic cylinder piston rod and Connection Block between be provided with and detect bindiny mechanism, can in the fast lifting process, detect abnormal signal, according to this signal instruction system automatic deloading, guarantee the lifting device of the fine blanking press slide block safe in utilization of mould and lathe.
The purpose of this utility model is achieved in that its connects fuselage and slide block, and it is made up of the Connection Block that is connected in hydraulic cylinder on the fuselage, is connected the slide block side, and the piston rod of hydraulic cylinder and Connection Block pass through detection bindiny mechanism.
Be provided with the warning oil circuit in the described hydraulic cylinder, it is axial that the warning oil circuit is located at hydraulic cylinder piston rod, is communicated with the hydraulic cylinder cavity of resorption with outside.
Described detection junctor be included in the flange that is provided with on the Connection Block, the groove that is opened in the flange end opening, bottom portion of groove detection oil circuit interface, be fixed on the piston rod top connector, be provided with mesopore and be fixed on gland on the Connection Block bottom surface; The connector axial cross section is a T shape, fixedlys connected with piston rod in the bottom, and bottom and gland mesopore flexibly connect, and the bottom axial height is slightly larger than the height of gland.
The utility model has been set up testing agency in the bindiny mechanism of piston rod and Connection Block, when slide block is in service when running into foreign matter, the detection oil pocket pressure that groove on connector, the flange, gland constitute can suddenly change, send the abnormal signal that pressure changes, instruction system automatic deloading then, shutdown inspection; Avoid mold damage, equipment, guarantee the safe in utilization of mould and lathe.The utility model had both improved operating efficiency widely, also can guarantee the safe in utilization of mould and lathe.

Accompanying drawing is the utility model structural representation;
Among the figure, the 1st, flange, the 2nd, gland, the 3rd, connector, the 4th, warning oil circuit interface, the 5th, hydraulic cylinder, the 6th, Connection Block, the 7th, detect the oil circuit interface.
The specific embodiment
As figure, its connects fuselage and slide block the utility model, and it is made up of the Connection Block 6 that is connected in hydraulic cylinder 5 on the fuselage, is connected the slide block side, and the piston rod of hydraulic cylinder 5 passes through detection bindiny mechanism with Connection Block 6.
Be provided with the warning oil circuit in the hydraulic cylinder 5, it is axial that the warning oil circuit is located at hydraulic cylinder piston rod, is communicated with the hydraulic cylinder cavity of resorption with outside, and warning oil circuit interface 4 is located at piston rod top.
Detect detection oil circuit interface 7, the connector 3 that is fixed on the piston rod top that junctor is included in the flange 1 that is provided with on the Connection Block 6, the groove that is opened in flange 1 end opening, bottom portion of groove, be provided with mesopore and be fixed on gland 2 on flange 1 bottom surface of Connection Block 6; Connector 3 axial cross sections are T shape, fixedly connected with piston rod in the bottom, and bottom and gland 2 mesopores flexibly connect, and the bottom axial height is slightly larger than the height of gland 2.
