Special-shaped punching device with adjustable precision

Abstract

The invention belongs to the technical field of punching devices, and particularly relates to a special-shaped punching device with adjustable precision. The device comprises a rack, a supporting frame is fixedly arranged at the top end of the rack in a screwed mode, a case is arranged at the top of the supporting frame, a workbench is arranged at the top of the case, the workbench is arranged atthe top of the case and fixedly connected with the case in a screwed mode, and a limiting baffle is arranged at the right end of the workbench; an adjusting plate is pulled, a sectional material is locked, a control switch for a pushing motor and a cutter is turned on, the pushing motor is used for driving a lead screw to rotate, a sectional material fixing base connected with the lead screw, a nut and a sliding rod can move back and forth on the workbench, the sectional material can be pushed forwards to perform cutting, cutting of the sectional material is safer and more stable, the phenomenon that workers are injured accidentally by a machine when the workers manually push the sectional material for cutting is avoided, the worker safety is improved, and the special-shaped material cutting stability and safety are enhanced.

Description

technical field [0001] The invention belongs to the technical field of punching devices, and in particular relates to a punching device for profiled materials with adjustable precision. Background technique [0002] Profiled material is a kind of material that is not flat but made into various shapes or with various surface carvings according to the design requirements of buildings. For a long time, plastic profiled material extrusion molding has always been a popular choice in my country's plastics processing industry. A relatively weak category uses a single-screw extruder, and the extrusion die produces profiled materials with relatively simple cross-sections at a low rate. Large-scale or super-large plastic profile production plants, the production capacity of doors and windows exceeds 120 million m², and the plastic profile extrusion die is hereinafter referred to as extrusion die, which is one of the key technologies for plastic doors and windows. The development of the ...

AI Technical Summary

Problems solved by technology

[0004] 1. The profile is large in size. Generally, when cutting, the staff needs to hold the profile to push the movement of the profile. There is a phenomenon that the machine accidentally injures the staff during the pushing process, which reduces the safety of the staff, and there is a greater safety hazard. Hidden dangers, reducing the cutting stability and safety of profiled materials

[0005] 2. When using a sliding table saw to cut profiled materials, because the plate is not easy to fix, it is easy to be shifted by the cutting force of the cutting knife during cutting, which affects the cutting accuracy of profiles and reduces the cutting efficiency of profiled materials
