Abstract
The utility model discloses a kind of hard alloy cutter, comprise carbide chip, carbide alloy knife bar and carbide cutter tool groove, wherein carbide alloy knife bar and carbide cutter tool groove are the integrated design, carbide cutter tool slot is in the end of carbide alloy knife bar, carbide chip and carbide chip are connected and fixed by sieve stem nut and shape is agreed with mutually, and the blade of carbide chip is exposed to outside the edge of carbide cutter tool groove after installing, also be provided with the cooling channels of a spiral in carbide alloy knife bar, be convenient to cooling.After the utility model blade is scrapped, can change, avoid the waste of knife bar; Cooling channels is in process simultaneously, plays certain cooling effect, is conducive to the temperature reducing blade, improves cutting speed and machining accuracy.
Description
Technical field
The utility model relates to a kind of hard alloy cutter, belongs to Machining Technology field.
Background technology
It is high that carbide alloy has hardness, anti abrasive advantage, be widely used and lathe process cutter, general blade and knife bar are all one, in mechanical processing process, need to use milling cutter to mill out end face, inclined-plane, groove or step surface to different workpiece, blade due to long-term wearing and tearing, the impact of high temperature etc., its service life is very short, so all will scrap together with knife bar, thus produce waste.And in process, between cutter and workpiece, friction can produce a large amount of heats, also accelerates scrapping of blade further, also affects machining accuracy.
Utility model content
The purpose of this utility model is to provide a kind of hard alloy cutter, and blade and knife bar are flexibly connected, replaceable, and in milling process, can cool cutter and processing work.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of hard alloy cutter, comprise carbide chip, carbide alloy knife bar and carbide cutter tool groove, described carbide alloy knife bar and carbide cutter tool groove are the integrated design, described carbide cutter tool slot is in the end of carbide alloy knife bar, described carbide cutter tool groove agrees with mutually with the shape of carbide chip, and the blade of carbide chip is exposed to outside the edge of carbide cutter tool groove, be provided with a screwed hole in described carbide cutter tool groove, described carbide cutter tool groove and carbide chip adopt the mode of bolt and nut to be connected and fixed.
A cooling channels is provided with in aforesaid carbide alloy knife bar.
Aforesaid cooling channels extends to carbide cutter tool groove end from carbide cutter tool boom end.
Aforesaid cooling channels is helical form.
The thickness of aforesaid carbide cutter tool groove is 5-8cm, and the opening diameter of cooling channels is 3-5cm.
The thickness of aforesaid carbide cutter tool groove is 8-12cm, and the opening diameter of cooling channels is 5-8cm.
Blade of the present utility model and knife bar are flexibly connected, and to connect be carried out under normal temperature state, avoid high-temperature soldering, can not affect the wearability of blade, extend the service life of blade, and after blade scraps, can change, avoid the waste of knife bar; Meanwhile, the utility model is provided with cooling channels, in process, plays certain cooling effect, is conducive to the temperature reducing blade, improves cutting speed and machining accuracy.
Accompanying drawing explanation
Fig. 1 is the structural representation of hard alloy cutter of the present utility model.
Detailed description of the invention
Now with detailed description of the invention, the utility model is described in further detail by reference to the accompanying drawings.
As shown in Figure 1, hard alloy cutter of the present utility model comprises carbide chip, carbide alloy knife bar 2 and carbide cutter tool groove 4, wherein carbide alloy knife bar 2 and carbide cutter tool groove 4 are the integrated design, carbide cutter tool groove 4 is positioned at the end of carbide alloy knife bar 2, carbide cutter tool groove 4 agrees with mutually with the shape of carbide chip, and the blade of carbide chip is exposed to outside the edge of carbide cutter tool groove 4.In carbide cutter tool groove 4, be provided with a screwed hole 3, carbide chip also arrange a through hole, carbide chip is fastened in carbide cutter tool groove 4 by bolt and nut.Carbide chip and carbide cutter tool groove adopt the mode of bolt and nut to be connected and fixed, and just avoid high-temperature soldering, can not affect the wearability of blade, and when blade abrasion has been scrapped, only need more allowing blade replacement, knife bar can reuse, and economizes on resources.
Preferably; a cooling channels 1 is provided with in carbide alloy knife bar 2; this cooling channels 1 extends to carbide cutter tool groove end from carbide cutter tool boom end; in process; inject cooling medium in cooling channels 1, effectively can take away cutter and the fricative heat of workpiece, be conducive to the cooling of blade; protect blade further, extend the service life of blade.
Preferably, cooling channels of the present utility model is helical form, and helical form more can increase the collection area to heat compared with straight line, and efficiency is higher.
Preferably, the opening diameter of cooling channels of the present utility model is relevant with the thickness of carbide cutter tool groove, if the thickness of carbide cutter tool groove is 5-8cm, then the opening diameter of cooling channels is that 3-5cm is optimum; If the thickness of carbide cutter tool groove is 8-12cm, then the opening diameter of cooling channels is that 5-8cm is optimum.
Claims (6)
