Embodiment Construction
[0013] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0014] figure 1 with figure 2 The shown longitudinal extrusion and fixing device for a CNC bending machine includes a working base 1, a main frame 2 located at both ends of the working base 1 and a hydraulic mechanism 3 fixed on the top of the main frame 2. The lower end of the hydraulic mechanism 3 is connected with a bending machine. The slider 4 of the upper mold, the upper surface of the working base 1 is located below the slider 4 and is provided with an installation groove 5, and the inner side wall of the main frame 2 is located on both sides of the installation groove 5 and is provided with an extrusion groove 6 communicating with the installation gr...

The invention relates to the technical field of forging and stamping, in particular to a vertical extruding-fixing device for a CNC bending machine. The vertical extruding-fixing device comprises a working base, a main rack positioned at the two ends of the working base, and a hydraulic mechanism fixed at the top end of the main rack, wherein a sliding block provided with an upper die of the CNC bending machine is connected with the lower end of the hydraulic mechanism; and a mounting groove is formed in the upper surface of the working base and positioned below the sliding block. The vertical extruding-fixing device provided by the invention has the advantages that an extruding groove communicating with the mounting groove is formed in the inner side wall of the main rack, an adjusting groove where a transmission box is built is formed in the outer side wall of the main rack, a lifting lead screw is driven by utilizing a manual wrench on the transmission box to rise and fall inside a transmission through hole, and the surface of a lower die is fixed by utilizing an elastic extruding plate at the lower end of the lifting lead screw, thereby greatly improving the mounting firmness of the lower die; meanwhile, the mounting and dismounting process is simpler; and the specifications of the utilized lower die are further diversified.
Description
technical field [0001] The invention relates to the technical field of forging, in particular to a longitudinal extrusion fixing device for a numerically controlled bending machine. Background technique [0002] The CNC bending machine controls the up and down movement of the oil cylinder through the numerical control system, thereby driving the mold installed on the slider to move up and down, and squeezes with the lower mold installed on the workbench to realize the bending of the workpiece. The lower mold of the bending machine is mainly installed and fixed by fixing bolts, which is cumbersome to assemble and disassemble, and the bolts and screw holes are rusted after long-term use, which increases the difficulty of disassembly, which is very inconvenient, and the applicable specifications of the lower mold are also very limited. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to solve the problems existing in ...
