Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic trimming machines, in particular to a hydraulic die-cutting machine. Background Art

[0002] A cutting machine is a common piece of equipment used for fabric cutting. During operation, a movable die base mounted on the cutting machine is driven by a power source to move along a guide rail. Once it reaches a set position, the die mounted on the die base presses down to cut the material, creating pieces that match the die's shape, thus completing the cutting process.

[0003] Most current die-cutting machines use a hydraulic pump as their drive mechanism, pushing the moving die to press the material against the die to be cut and shaped. During operation, the hydraulic cylinder is prone to oil leakage at the inlet and outlet ports, requiring regular replacement. Leaked hydraulic oil can also affect product aesthetics and production quality. Furthermore, the existing pressing table is subject to significant forces during the pressing process, making it prone to fatigue fracture or deformation, impacting production and processing.

[0004] In view of the problems existing in the above-mentioned prior art, the present invention designs and manufactures a hydraulic die-cutting machine to overcome the above-mentioned defects. Utility Model Content
