Description
Technical field
The utility model relates to a kind of forcing press.
Background technology
At present, cylinder is when reel, its round edge joining place needs to carry out transition by forcing press bending certain angle, thus after cylinder is welded to connect, circularity is better, when the current sheet material for large-scale cylinder carries out bending, because sheet metal thickness is thicker, the forcing press needing tonnage larger is processed, but the auxiliary facility of large pressing machine requires higher, thus add production cost, be badly in need of that a kind of structure is simple, the forcing press of good stability solves this technical problem.
Summary of the invention
The purpose of this utility model is to overcome the defect existed in prior art, provides a kind of forcing press, and structure is simple, good stability, and intensity is higher.
For achieving the above object, the technical solution of the utility model there is provided a kind of forcing press, comprise C-shaped frame, described upper rack is provided with hydraulic cylinder, the piston rod of described hydraulic cylinder is fixedly installed staking punch, described hydraulic cylinder rushes liquid fuel tank by the first oil pipe and first and is connected, described first rushes liquid fuel tank is connected with second by the second oil pipe and rushes liquid fuel tank, described second rushes on liquid fuel tank and is provided with oil pump, described frame offers host cavity, the cylinder body of described hydraulic cylinder is positioned at described host cavity, cylinder body and the described frame of described hydraulic cylinder are fixedly connected, the cylinder body bottom of described hydraulic cylinder is provided with annular plug, the cross section of described annular plug is T-shaped, the internal diameter of described annular plug matches with the piston rod of described hydraulic cylinder, its external diameter coordinates with the cylinder diameter shape of described hydraulic cylinder, the cylinder body of described annular plug and described hydraulic cylinder is fixedly connected, rush liquid valve by butterfly between described first oil pipe and the cylinder body of described hydraulic cylinder to be connected, the end of described first oil pipe is provided with the first high pressure flange, the cylinder body of described hydraulic cylinder is provided with the second high pressure flange, described first high pressure flange is connected with described second high pressure flange, described butterfly is rushed liquid valve and is positioned between described first high pressure flange and described second high pressure flange.
Further improvement: between described annular plug and the cylinder body of described hydraulic cylinder, is respectively arranged with seal between described annular plug and the piston rod of described hydraulic cylinder.
Further improvement: described first oil pipe and described second oil pipe are respectively arranged with butterfly valve.
Further improvement: described frame lower is work-piece platform, described work-piece platform is mutually concordant with workshop terrace.
Advantage of the present utility model and beneficial effect are: structure is simple, good stability, intensity are higher, and is convenient to the maintaining of piston by arranging annular plug.
