Problems solved by technology

The existing mobile gantry type leveling hydraulic press with small tonnage and small table has a cantilever structure for the rollers at the bottom of the gantry, and the poor stress state makes the roller shaft easy to bend and deform, resulting in an increase in the gap between the gantry and the workbench guide rail. Therefore, the original leveling hydraulic machine is in There are 4 lifting cylinders installed at the bottom of the gantry, which can be lifted up to make the gantry fully contact with the guide rail of the workbench, so as to eliminate the vibration impact caused by the large gap, so the structure is more complicated; in addition, there are master cylinders and punches for walking on the gantry The walking trolley is driven by a chain, so the displacement accuracy is poor, and the purpose of accurate leveling of the workpiece is often not achieved.

Embodiment Construction

[0014] In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0015] Please refer to Fig. 1 and shown in Fig. 2, the fixed workbench 17 is a cuboid, the center part of the fixed workbench is equipped with a jacking cylinder 18 for jacking up the workpiece, and both sides of the fixed workbench are equipped with upper guide rails 20 and lower guide rails 19 The gantry 12 across the two sides of the fixed workbench is installed between the upper and lower guide rails on both sides of the fixed workbench. The bottom of the gantry is equipped with guide wheels 13 rolling on the guide rails on the fixed workbench. A support plate 12-2 integrally welded with the gantry is fixedly installed, as shown in Figure 3 . A toothed roller 16 rolling on the lower guide rail of the fixed workbench is installed between t...

Abstract

This invention provides movable portal digital-control heavy-plate leveling hydrostatic machine, which is characterized in that, arranging portal on fixed guide rail, welding support plate on wall side of portal bottom, arranging gear roller on guide and joggled small gear and drive motor; arranging leading screw with one end connected to drive frequency conversion motor and leading screw nut on dolly bottom; arranging two side cylinders on main cylinder sides; arranging dust brush on bearing plate to clear dirty on plant. The invention improves the precision, simplifies structure and increases service life.

Description

technical field [0001] The invention relates to a hydraulic press for leveling metal plates, in particular to a mobile gantry type digitally controlled thick plate leveling hydraulic press. Background technique [0002] At present, in the automobile industry and shipbuilding industry, the plates of large welded parts (thick plates), especially the thick plates, need to be leveled before assembly, which can reduce the amount of cutting on the machined surface and save raw materials. The existing mobile gantry type leveling hydraulic press with small tonnage and small table has a cantilever structure for the rollers at the bottom of the gantry, and the poor stress state makes the roller shaft easy to bend and deform, resulting in an increase in the gap between the gantry and the workbench guide rail. Therefore, the original leveling hydraulic machine is in There are 4 lifting cylinders installed at the bottom of the gantry, which can be lifted up to make the gantry fully conta...
