specific Embodiment approach 1

[0008] Specific implementation mode one: combine Figure 3-Figure 5 To illustrate this embodiment, the cylinder-beam integrated hydraulic press of this embodiment includes an upper die 6, a lower die 7, a workbench 15 and two return cylinders 11, and the hydraulic press also includes a housing 13, a slider 14, and a thrust plunger 16 , a sealed guide sleeve 18, a cage 20, a fixed plate 19, two guide sleeves 22, two guide posts 23 and a plurality of legs 27, the inner wall of the housing 13 is fixedly equipped with a cage 20, the cage 20 is fixed with a sealed guide sleeve 18, the thrust plunger 16 is set in the sealed guide sleeve 18, and moves up and down in the sealed guide sleeve 18, the cage 20, thrust plunger 16, belt The sealed guide sleeve 18 and the upper part of the housing 13 form a high-pressure fluid chamber 21, and the lower end surface of the thrust plunger 16 is provided with a slider 14, the slider 14 is an inverted concave slider, and the upper mold 6 is fixed...

specific Embodiment approach 2

[0009] Specific implementation mode two: combination image 3 and Figure 4 The present embodiment will be described. The casing 13 of the present embodiment has a thickness smaller than 1 / 40 of its outer diameter. With such arrangement, the quality of the hydraulic press is lighter. Other compositions and connections are the same as in the first embodiment.

Abstract

The invention discloses a cylinder beam integrated hydraulic press relating to a hydraulic press. The invention solves the problems that the rigidity and the strength of the upper crossbeam of the traditional three-beam four-pillar hydraulic press are weakened by a working cylinder hole, the upper crossbeam and a lower crossbeam are easy to get loose from the threaded connection with pillars and the complete machine has big weight and high cost. In the scheme I, the inner wall of a shell is fixedly provided with a retainer; a guide sleeve with a seal is fixedly arranged in the retainer; a thrust plunger is arranged in the guide sleeve and makes movement up and down; the lower end of the thrust plunger is connected with a slider; an upper die is fixedly arranged on the bottom end surface of the groove of the slider; a fixing plate is horizontally and fixedly arranged in a stand; the fixing plate is provided with a worktable; the worktable is provided with a lower die; and the lower dieand the upper die correspond; the main difference between the scheme II and the scheme I lies in that the inner wall of the shell is fixedly provided with an annular check ring; the annular check ring and a pressure resistant elastic element are sleeved outside the thrust plunger; and the upper die is fixedly arranged on the slider of the lower end of the thrust plunger. The invention has the advantages of low height of the complete machine, light weight, big total pressure and low cost.

Description

technical field [0001] The invention relates to a hydraulic machine, in particular to a cylinder-beam integrated hydraulic machine, which belongs to the technical field of hydraulic equipment. Background technique [0002] Hydraulic press is a general-purpose equipment, commonly used in sheet metal forming and bar forging in the fields of automobile manufacturing, aircraft manufacturing, shipbuilding and light industrial product manufacturing, as well as hot isostatic pressing and cold isostatic pressing of powder bodies and non- Metal laminate pressing and brick pressing. The traditional hydraulic press is a three-beam and four-column structure, such as figure 1 and figure 2 shown. The working cylinder 1 bears the high-pressure fluid, and the fluid pressure in it pushes the rod 2 to move downward. The working cylinder 1 passes through the inner hole in the middle of the upper beam 3 and is fixed in the upper beam 3 with a flange. There are four columns 4 for the movable...
