Abstract
The utility model discloses a locking device for the operating platform of a multifunctional oil press and relates to the auxiliary device of the oil press in metallurgical enterprises. The locking device comprises a hydraulic cylinder, locking pins and a detection device, wherein, the hydraulic cylinder consists of a cylinder body and a piston rod, and the cylinder body is fixed on a structural member in the upright post of the oil press with a double-headed bolt; the protruding head part of the piston rod is connected with the wedge-shaped locking pin, and the guide sleeve of the wedge-shaped locking pin is fixed on the structural member in the upright post of the oil press with pressing plates and bolts; the joint of the tail part of the wedge-shaped locking pin and the piston rod is connected with a monitoring rod by screw threads, and the monitoring rod passes through a sleeve arranged on the flange of the cylinder body; a monitoring ring is arranged at the end part of the monitoring rod, and limit switches are arranged on the supporting plate of the monitoring ring. When entering the cylinder body, oil pushes the piston rod and the wedge-shaped locking pin to lock the operating platform; when the oil enters the cavity of the piston rod, the wedge-shaped locking pin is driven to leave the operating platform by the piston rod. The utility model has the characteristics of novel structure, great clamping force, simple structure, practicality, and the like, so the utility model belongs to a novel locking device integrated economy with practicality.
Description
Technical field
Multi-functional hydraulic press table latch device described in the utility model relates to a kind of servicing unit of smelter hydraulic press.
Background technology
The progress of making rapid progress at present along with science and technology, China's metallurgy profession is developed to non-ferrous metal by single Summoning, and titanium sponge is exactly wherein a kind of novel and important material.My company is that the 80/100MN hydraulic press of the exploitation of Shanghai Baosteel Shanghai five steel Co., Ltds, development is exactly the hydraulic press (this press also is applicable to isothermal die forging process) that is used to suppress the titanium sponge electrode.
Table latch device in the past mostly is the rod-pulling type structure, and simple rod-pulling type structure clamping force is little, and coupling mechanism force is generally below 100 tons, and it is moving that workbench when work string takes place, influence compacting precision.Along with the progress of Forging Technology, moulding process is increasingly sophisticated, and more and more higher to the requirement year of table latch device coupling mechanism force, the table latch device of rod-pulling type structure is difficult to satisfy the requirement of large-tonnage hydraulic press.At existing problem in the above-mentioned prior art, a kind of novel multifunctional hydraulic press of research and design table latch device, existing problem is very necessary in the prior art thereby overcome.
Summary of the invention
In view of existing problem in the above-mentioned prior art, the purpose of this utility model is a kind of novel multifunctional hydraulic press of research and design table latch device, tightly to install clamping force little thereby solve rod-pulling type arrangement works stand lock, and it is moving that workbench when work string takes place, problems such as influence compacting precision.Multi-functional hydraulic press table latch device described in the utility model is made up of hydraulic cylinder, wedge shape lock pin and checkout gear.Its structure is that hydraulic cylinder is made up of cylinder body and piston rod.Cylinder body is fixed on the multi-functional hydraulic press column inner structure part by stud, piston rod stretches out head and is connected with the wedge shape lock pin, the guide pin bushing of wedge shape lock pin is with pressing plate and being bolted on the multi-functional hydraulic press column inner structure part, the afterbody of wedge shape lock pin and piston rod junction next door is with the monitoring rod that is threaded, monitoring rod passes the cover that is installed on the cylinder body flange, and detection ring is equipped with in its end.Two limit switches are housed on the support plate at detection ring place.Hydraulic cylinder described in the utility model, wedge shape lock pin and checkout gear are provided with 2-6 covers according to the big I of workbench.
The multi-functional hydraulic press table latch device course of work described in the utility model is to lock workbench forward when cylinder body advances pressure oil promotion piston rod drive wedge shape lock pin.Wedge shape lock pin front end and workbench contact jaw are square, and the bottom surface is the inclined-plane.Rear side and cylinder body link are cylindrical.Detect pole-footing and move with the wedge shape lock pin, the detection ring of test rod end operates between two limit switches, and the stroke of control wedge shape lock pin sends and is clamped to bit data.Test rod also plays guide effect.When the rod end chamber oil-feed, the wedge shape lock pin under the drive of piston rod backward travelling table unclamp.
The utlity model has novel structure, wedge shape lock pin, advantages such as clamping force is big, features simple structure is compact, practicality, it puts goods on the market in enormous quantities and will produce positive social benefit and remarkable economic efficiency.
