Description
Technical field
The utility model belongs to control specific machine technical field, be specifically related to the two-sided special purpose grinder of digital-control two-head that a kind of grinding cutter is cut, be mainly that lathe one stroke completes two-sided thick, fine ginding, raising working (machining) efficiency and machined surface precision while utilizing double power head and double abrasive wheel mechanism to solve high efficient grinding Household knife to cut, adopt the process issues such as double power head structure.
Background technology
In recent years, cutter is cut hardware products industry larger development, and export trade volume is increasing year by year, according to statistics in 2012, China is engaged in cutter and cuts the enterprise of production and approximately have 3,000, approximately more than 100 hundred million yuan of scissors products year total industrial output values, and a year foreign exchange earning exceedes 400,000,000 dollars.Daily hardware products is as kitchen knife, cover cutter, pocket knife, Stupalox and industrial scissors, Scissors, dressmaker's shears etc., because there being quite high hardness just can reach its sharpness and durability, so mostly all will reach by grinding process sharp requirement, physical dimension requirement and the appearance requirement of shear surface and cutting edge.In the international market, the scissors products of China main or take in, the low value-added product of low side is as main.Up to the present, also there is not the scissors products of the world-famous brand such as picture Germany " one of the Chinese character components ", Japan's " Zhuan Shanlang " board, cause the basic reason of gap to be: product quality and processing cost are high.Main cause is that the current cutter of China is cut numerical-controlled grinder special and aspect machining accuracy and working (machining) efficiency, also could not reached high request.
Current grinding cutter is cut special purpose grinder and is mainly contained two kinds, a kind of is the numerical control special purpose grinder that clamped one time is realized one side grinding, its processing technology is: on same grinding machine, adopt workbench back and forth working in reciprocating mode move and realize the one side grinding that cutter is cut, grinding accuracy is high, but grinding efficiency is low; Another kind is the hydraulic pressure special purpose grinder that clamped one time is realized double-side grinding, and its processing technology is: one stroke grinding is simultaneously two-sided, and operating efficiency is high, but machining accuracy is unstable, precision is low, is mainly used in processing the low product that requires.Therefore researching and developing the numerical control special purpose grinder that a kind of high efficiency, high accuracy double-side grinding cutter cut and seem very important, is the numerical control Special grinding turning equipment that improves grinding cutter scissors products efficiency, precision.
Summary of the invention
The purpose of this utility model is to overcome existing technology limitation and not enough, provides a kind of pair of grinding wheel head structure, that clamped one time is thick, fine grinding sharpener is cut is two-sided, be applicable to the two-sided specialized nc machine tool of digital-control two-head that plurality of specifications and various material cutter are cut grinding.
The digital-control two-head special purpose grinder that a kind of double-side grinding cutter that the utility model provides is cut, emery wheel in two wheel grinding devices is oppositely arranged grinding cutter simultaneously and cuts two sides, every wheel grinding device is arranged on respectively on a bistrique upper saddle that can move as X-axis, between the emery wheel in two chaptrel grinding attachments, is provided with and can fixes the worktable part that cutter to be ground is cut; Worktable part is arranged on the workbench upper saddle that can move as Z axis, and when workbench upper saddle moves as Z axis, worktable part can be cut by cutter corresponding swing of circular arc camber work of required processing.
Worktable part one end is arranged on by front hinged seat on the workbench upper saddle that can move as Z axis, other end vertical support is on pattern back shaft, workbench upper saddle is arranged on the workbench lower slider that can move as Z axis, front hinged seat can make worktable part swing up and down in the time that grinding is worked, and recalls in advance certain angle of inclination when rear hinged seat can make mounting cutter workpiece.
Oscillating control mechanism comprises the pattern back shaft composition that is fixed on the pattern chi of pattern seat bottom and move by required running orbit for pattern chi, forms with institute's grinding cutter and cuts the corresponding lonely shape face of circular arc camber in pattern chi bottom.
Rotatablely moving of emery wheel drives two spindle units to complete by two main motors, and the motion of Z axis is realized by a driven by servomotor, and the motion of X-axis, by two driven by servomotor move toward one another, reaches the effect of double-side grinding.
When tool grinding, Cutting tool installation manner is upper in knife rest (special fixture), is moved and is realized principal feed motion by workbench pattern clamping component controls Z axis; Move and realize the two-way cutting-in feeding of grinding and move by the X-axis of two upper saddles; Realized the arc surface control grinding of tool face by swinging up and down of pattern; Realize double-side grinding by simultaneously grinding of double abrasive wheel, realized on same a machine tool the once processing technology of the thick smart double-side grinding of stroke.
The beneficial effects of the utility model are:
Realize the Roughing and fine machining that clamped one time completes cutter and cut circular arc camber, improve working (machining) efficiency, solved cutter and cut the problems such as working (machining) efficiency is low, cost is high, Surface Machining precision is low.Effectively shorten process time, reduced labour intensity, reduced labour cost, improved operating efficiency and economic benefit.Reach object high-precision, high efficient grinding.
High rotating speed, high efficiency, high-precision grinding that the speed of mainshaft reaches 4000r/min, grinding depth and reach 0. 4 ㎜/cutter, positioning precision and reach 0.002 ㎜ and 30～40s/ part are realized smoothly.
