Abstract
The utility model relates to a device for cutting metal by utilizing light energy for heating, in particular to a light collecting cutter, which comprises a convex lens and a concave lens which are coaxially arranged from top to bottom, a section of inner pipe is connected below the concave lens, and a cutting mouth provided with an open hole is arranged at the lower end of the inner pipe. A parallel incidence light source is arranged above the convex lens, parallel light is converged by the convex lens and then is converged again by the concave lens, and a repeatedly converged focus is located near to the position below the cutting mouth. The light collecting cutter improves the strength of the incidence light on a unit area, and simultaneously light beam approximate to the parallel light also enables the work range of the light collecting cutter in the axial direction to be increased, so that a cutting effect similar to laser is achieved. The light collecting cutter is used for cutting the metal, simple in structure and convenient to operate and maintain.
Description
Technical field
The utility model relates to a kind of device that utilizes light energy pyrogenicity to carry out Metal Cutting, specifically is a kind of light harvesting cutter.
Background technology
The existing device that utilizes light energy to carry out Metal Cutting is generally laser cutter, and this kind equipment need be provided with the generating device of laser of expensive, has increased purchasing and use cost of equipment greatly, and its device structure is complicated simultaneously, is unfavorable for operation and maintenance.
Summary of the invention
The utility model technical problem to be solved is, a kind of Metal Cutting, simple in structure, operation maintenance light harvesting cutter easily that can be used for is provided.
The light harvesting cutter of the utility model includes convex lens and concavees lens of coaxial setting from top to bottom, and the concavees lens below is connected with pipe in a section, and interior pipe lower end is provided with the cutting head with perforate; The convex lens top is provided with parallel incident light source, and directional light is below the focus below the convex lens is positioned at concavees lens, and directional light focuses on through concavees lens after converging through convex lens more again, and the focus that focuses on again is positioned near the cutting head below.
Said parallel incident light source is single wavelength light source.
The pipe upper end is tightly connected with concavees lens in said, and the inner chamber of interior pipe is connected with compressed gas source with the air intake valve through blast pipe.
The pipe periphery is with an outer tube in said, and outer tube is provided with cooling liquid inlet and the cooling liquid outlet that is connected with coolant circulation system, and other of outer tube are partially enclosed.
Be connected with between said outer tube and the interior pipe and strengthen gusset longitudinally.
Be provided with the moving stop that to open or to cover incident light source between said convex lens and the incident light source.
Said moving stop is by air cylinder driven.
The utility model is through the concave-convex lens combination; The zoom in of lens; The light harvesting bundle cutting angle that final arrival is cut on the workpiece approaches directional light; Both improved the incident ray intensity on the unit are, its light beam near directional light also makes its working range in the axial direction increase greatly simultaneously, thereby produces the cutting effect of similar laser; Its cutting head can be exported compressed air stream in high-temperature machining, cutting part can be separated smoothly, has guaranteed cutting effect; Through being arranged on reinforcement gusset and the circulating cooling liquid between inner and outer pipe, improved the ability of interior pipe opposing temperature distortion, guaranteed cutting accuracy.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the A cross section structure sketch map of Fig. 1.
The specific embodiment
As shown in the figure, this light harvesting cutter includes convex lens 1 and concavees lens 2 of coaxial setting from top to bottom, and the concavees lens below is connected with in one section manages 3, and interior pipe lower end is provided with the cutting head 4 with perforate; Convex lens 1 top is provided with the parallel incident light source of single wavelength, and directional light is below the focus below the convex lens is positioned at concavees lens, and directional light focuses on through concavees lens after assembling through convex lens more again, and the focus that focuses on again is positioned near the cutting head below.
Interior pipe 3 upper ends and concavees lens 2 are tightly connected, and the inner chamber of interior pipe is connected with compressed gas source with air intake valve 6 through blast pipe 5.Interior pipe periphery is with an outer tube 7, and outer tube is provided with the cooling liquid inlet 8 and cooling liquid outlet 9 that is connected with coolant circulation system, and other of outer tube are partially enclosed.Be connected with between outer tube and the interior pipe and strengthen gusset 10 longitudinally.Be provided with the moving stop 11 that to open or to cover incident light source between convex lens and the incident light source.Moving stop is driven by cylinder 12.
In the utility model course of work, directional light prolongs focal length through concavees lens through convex lens focus again, thereby near focus, forms bigger effective depth of cut, utilizes the impact of air-flow to make cutting part to separate smoothly in the cutting process.
