Abstract
Provided is a cutting device for a hydraulic pressure rivet cap. A cylinder body and a front cover are sealed to form a sealed cylinder. A piston is installed in the cylinder body and can move in a reciprocating mode. A safety valve rod is inserted in the piston. The front cover is in thread connection with the cylinder body. A connecting rod is connected to the piston through threads. A knife rest connecting base is connected to the connecting rod through threads. A knife rest is hinged to the knife rest connecting base through a pin. An oblique cone is connected to the front cover through threads. A first blade and a second blade are fixed on the knife rest. The cutting device for the hydraulic pressure rivet cap achieves rivet disassembly in a mechanical mode, can cut rivets, meanwhile protects base materials, reduces labor intensity, and improves working efficiency.
Description
Technical field
The utility model relates to a kind of power tool, is specifically related to the hydraulic pressure pulling rivet instrument of a kind of railway freight-car industry and heavy industry industry.
Background technology
For a long time, in railway freight-car industry and heavy industry industry, because rivet error or need to dismantle pulling rivet when repairing the time will destroy the rivet collar operation, existing operation all is to adopt the flame cutting, and this mode injures mother metal easily, and operation is trouble also.
Summary of the invention
Technical problem to be solved in the utility model is: solve the problem that above-mentioned prior art exists, and the hydraulic pressure rivet cover grinder that a kind of mechanical system removing rivet is provided, does not injure mother metal, reduce labour intensity, increase work efficiency.
The technical solution adopted in the utility model is:
This hydraulic pressure rivet cover grinder, cylinder body and protecgulum sealing form the cylinder of a closure, piston is contained in the cylinder body and can moves back and forth, safety lever is inserted in the piston, and protecgulum and cylinder body are threaded, and connecting rod is threaded connection on piston, the knife rest Connection Block is threaded connection on connecting rod, knife rest is hinged on the knife rest Connection Block by pin, and oblique cone is threaded connection on protecgulum, and the first blade and the second blade are fixed on the knife rest.
Operation principle:
The oil-feed of cylinder body ante-chamber, piston backward be dynamically connected bar and knife rest Connection Block of Sports band moves backward, knife rest on the Connection Block just moves along oblique cone, so just realized shearing motion, shear complete after, the oil-feed of cylinder body back cavity, piston driving connecting rod and knife rest Connection Block move forward, knife rest opens, and enters next duty.
Advantageous effect
The utility model has been realized the mechanical system removing rivet, can cut brokenly, has protected again mother metal, has reduced labour intensity, has promoted operating efficiency.
Description of drawings
Fig. 1 is the utility model structure cutaway view.
The accompanying drawing marking explanation:
The 1-knife rest, 2-pin, 3-knife rest Connection Block, 4-oblique cone, 5-connecting rod, 6-the first blade, 7-the second blade, 8-protecgulum, the sealing of 9-protecgulum, 10-safety lever, 11-piston, 12-cylinder body.
The specific embodiment
Referring to Fig. 1; cylinder body 12 of the present utility model and protecgulum sealing 9 form the cylinder of a closure; piston 11 moves reciprocatingly in cylinder body; safety lever 10 is inserted in the piston 11; shield; protecgulum 8 and cylinder body 12 are threaded; play the fixedly effect of protecgulum sealing; connecting rod 5 is threaded connection on piston 11; and along with piston moves reciprocatingly together, the knife rest Connection Block is threaded connection on connecting rod 5, and knife rest 1 is hinged on the knife rest Connection Block 3 by pin 2; oblique cone 4 is threaded connection on protecgulum 8, and the first blade 6 and the second blade 7 are fixed on the knife rest 1.
