Description

Tool core replacing perforating machine Technical Field The invention relates to the technical field of office punching equipment, in particular to a tool-changing core punching machine with a conveniently replaceable tool core. Background Along with the improvement of office automation and individuation demands, demands for efficient and flexible punching and binding of sheet materials such as documents, notes, leather, artworks and the like are increasing. Consumers are pursuing convenience of operation and diversification of functions, and simultaneously, higher requirements are put on convenience of maintenance, labor saving of operation and compactness of the whole structure of the equipment. At present, the punching equipment on the market has the remarkable problems that the cutter core cannot be replaced or the replacement operation is complex, and the maintenance cost is high. The mainstream puncher adopts fixed tool bit or the complicated interchangeable sword design of structure generally, when the tool bit wearing and tearing or need switch the punching specification of different apertures/shapes, often need carry out loaded down with trivial details dismouting with the help of the instrument, dismantle a plurality of parts or adjust accurate counterpoint mechanism even, not only operation consuming time and consuming effort, still easily accelerate connection structure wearing and tearing, influence equipment precision and life-span. In addition, the existing equipment is single in function, punching and binding are usually completed step by step, even if a few devices integrating the binding function are used, the binding structure of the existing equipment is difficult to adapt to binding iron rings of different specifications, when users face the requirements of various binding sizes, the equipment still needs to be frequently adjusted or replaced, and the equipment is heavy and complex in operation and is difficult to meet the requirements of efficient operation. Therefore, the invention provides a tool changing core puncher which can effectively solve the problems. Disclosure of Invention In order to overcome the defects in the prior art, the invention provides the cutter core replacing and punching machine which is simple in structure, the cutter cores are convenient to replace, and the binding structure can be adapted to binding iron rings with different specifications. The technical scheme adopted for solving the technical problems is as follows: A tool changing core punch comprising: A mounting base for carrying a sheet material to be perforated; The replaceable cutter core unit is detachably mounted on the mounting base and comprises a punching assembly; The control handle is rotatably connected to the mounting base, and the punching assembly of the replaceable cutter core unit is driven to move downwards by the rotation of the control handle so as to punch and punch the sheet-shaped material loaded on the mounting base; The iron ring pressing assembly comprises a pressing fixed plate and a pressing movable plate, when the control handle rotates downwards, the pressing movable plate moves towards the pressing fixed plate and presses the binding iron rings between the pressing fixed plate and the pressing movable plate, and the initial position of the pressing fixed plate is adjustable so as to adapt to binding iron rings with different specifications. The detachable type replaceable cutter core unit has the beneficial effects that through the arrangement of the structure and the detachable installation design of the replaceable cutter core unit, the equipment can flexibly adapt to the punching requirements of various sheet materials (such as paper, leather, plastic sheets and the like) by replacing the replaceable cutter core units with different specifications, so that the equipment acquisition cost is reduced, the later maintenance flow is simplified, and when the replaceable cutter core unit is worn or damaged, only the replaceable cutter core unit is required to be replaced independently, the equipment main body is not required to be disassembled, and the universality and the service life of the equipment are effectively improved. The integrated design of the iron ring pressing assembly combines the punching and binding functions into a whole, avoids the cost and occupied space of respectively purchasing two devices by a user, and is particularly critical that the initial position of the pressing fixing plate is adjustable, so that the device can adapt to binding iron rings with different specifications through simple operation, the user can quickly switch among various binding sizes without tools or changing accessories, and the flexibility and the efficiency of binding operation are obviously improved.
