The correct installation method for a hydraulic shearing machine
The frame of the hydraulic shearing machine is of welded steel plate construction, and the left and right wall panels, work tables, press beam, and cross members are welded together to form a frame structure with good rigidity. The left and right oil cylinders are installed respectively on the supports of the left and right wall panels and the upper part of the press beam, and the lower blade is fixed to the workbench. The left side of the worktable is equipped with a lateral stop mechanism (with a front stop mechanism) and the stop is positioned and counted with a ruler. The verticality of the lateral stop and the lower knife edge can be adjusted with the adjusting screw under the support arm.
The main body of the tool holder is a welded assembly with sufficient rigidity. The tool holder is supported by three-point roller guide rails. The tool holder is connected to the piston rod of the oil cylinder and performs a linear back-and-forth movement between the guide rails. The two rear pivots are fixed to the wall plate and the front pivot is the cup spring roller bearing fixed to the pressure beam so that the tool holder is always fixed to the two rear pivots. The mechanism for adjusting the kerf is a worm gear that drives the top pivot eccentrically so that the tool holder makes a slight rotation on the bottom pivot, changing the value of the gap.
The backgauge is attached to the base plate of the knife holder and moves up and down with the knife holder. The backgauge is driven by a servo motor and is driven by a toothed belt and a pair of ball screws to move the stop-frame back and forth on the linear guide. The entire backgauge is counted by the numerical control system, positioning is accurate and reliable and easy to operate. The adjustment range of the backgauge is 10~1000mm.
Note: When pushing the sheet to the stopper during positioning, lean against the stopper slightly to ensure the positioning accuracy, otherwise the positioning accuracy will be affected.
The installation accuracy of the machine tool directly affects the performance of the machine tool, so the installation of this machine tool must be done by professionals (or the manufacturer will send someone to the site). The machine tool must be installed on a stable and solid foundation, the floor of the working area must be covered with a thick layer of concrete according to the requirements of the foundation drawing and the level must be corrected (flatness 2mm/m). Fifteen days before installation, the user can first excavate the foundation and water the ground according to the foundation plan in the manual, provide four holes for the installation of the anchor bolts and make sure that the four leveling irons are placed at the indicated position, and install after the resting bed is set. After the cement has completely hardened, adjust the level of the machine using the support screws and the support plate, and then adjust the level of the work surface.
When adjusting the level of the work surface, remove the plate with the steel ball in the center of the work joint, place the spirit level on the raised machining surface of the work table and use the left and right support screws on the front of the machine tool to adjust the horizontal direction of the machine tool. Level; then set the level vertically and use the left and right support screws at the rear of the machine tool to set the longitudinal level of the machine tool. The horizontal and vertical levels should be checked within 1000: 0.2 mm.
