Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings.

[0021] As shown in Figure 1 and Figure 2, the horizontal pretension plate and frame hydraulic press. It includes front and rear racks, working hydraulic cylinder 3 installed on the rack, slider 4 connected to the hydraulic cylinder plunger, workbench 5 installed on the inner lower part of the rack, and return hydraulic cylinder 6. The front and rear racks respectively have three There are six plate frames in the front and rear racks, which are overlapped and combined by the pre-tensioning device 1 for horizontal fastening. The plate frame constitutes the frame of a hydraulic machine with load-bearing capacity, strength and rigidity. The working hydraulic cylinder is fixed on the upper part of the frame by the suspension device 7, and the bottom of the cylinder is in contact with the plate frame and bears the working load; the return hydraulic cylinder is suspended on ...

Abstract

A transverse prefastened plate-and-frame hydraulic press for making the parts of car is composed of the machine frame made of several individual plate frames combined by prefastener unit, transverse working hydraulic cylinder, returning hydraulic cylinder, slide blocks connected to returning hydraulic cylinder, and bench. Its advantages are high strength and rigidity, high load-bearing power, light weight, and high accuracy.

Description

[0001] Field [0002] The invention belongs to forging machinery equipment, in particular to a horizontal pre-tightening plate and frame hydraulic press used for forming auto parts. technical background [0003] Hydraulic press is a common equipment for forming various parts of auto parts and its equipment. The frame of the traditional hydraulic press adopts three-beam four-column or longitudinal pre-tightening frame structure, such as the Chinese Patent No. CN97232565.4 a kind of hydraulic (oil) press. It includes a lower beam (base), an upper beam (top seat), a column, an oil cylinder is installed on the top seat, a track frame is installed between the top seat and the base from top to bottom, a support frame, a reciprocating oil cylinder, a middle beam (middle slide block), pressure piston, etc. The upper and lower beams of these hydraulic machines are welded or cast structures, and the hydraulic cylinders are connected to the upper beams by flanges on the upper beams. A...
