Problems solved by technology
[0004] In order to solve the technical problems existing in the background technology, the present invention provides a forging press. The main cylinder body of the plunger cylinder has a prismatic overall structure with a centrally symmetrical regular N-gon in cross section, and a matching cylinder body. Adjust the flat copper guide device, through the combination of the prismatic cylinder structure and the flat copper guide device, effectively solve the problem of uneven force on the guide device when the master cylinder deviates

The invention discloses a forging press and a method for manufacturing a plunger cylinder thereof. The forging press comprises a main frame, an upper fixed cross beam, a pre-stress pull rod, a movable cross beam, a plunger cylinder, and a movable work table. The forging press is characterized in that a plunger cylinder body has a prismatic integral structure with a cross section being a central symmetry regular polygon with N sides, wherein the N is an integral multiple of 4; and a plurality of groups of the panel type guiding devices are lined between the plunger cylinder body and the main frame. The forging press and the method for assembling a plunger cylinder thereof have the advantages that a main cylinder body of the plunger cylinder and the guiding devices are in surface contact, and guide copper plates utilize adjustable structures, so that the operation stability of the forging press is increased, the abrasion of guide copper plates is reduced, and service lives of the copper plates are increased.
Description
technical field [0001] The invention belongs to the technical field of forging presses, and in particular relates to a forging press with a prism-structured plunger-cylinder body and a manufacturing method for the plunger-cylinder body. Background technique [0002] The forging press is a forging machine used for forming and separating in forging processed products, and transmitting working pressure with high-pressure liquid (oil, emulsion, etc.). The forging press works smoothly, without vibration, and can easily reach a large forging depth. It is most suitable for forging of large forgings and deep drawing, packing and briquetting of large-sized sheets. At present, the outer ring of the main cylinder body 18 of the known forging press plunger cylinder is circular, and a copper sleeve 19 guide structure is set between the cylinder body and the main frame 11. The gap between the guide copper sleeve 19 and the main cylinder 18 is not adjustable, and the machining accuracy Th...
