Abstract
The utility model discloses a combined type end mill. The combined type end mill solves the problems the existing hard alloy end mill has serious material waste, low shock resistance and the like. A threaded hole is formed in the central position on one end face of a cutter bar (3); and a threaded rod matched with the threaded hole of the cutter bar (3) is arranged at one end, without cutting edge, of a cutter head (1), so that the combined type end mill has the advantages of material saving, shock resistance and the like.
Description
Technical field
The utility model relates to a kind of metal-cutting machine tool, especially relates to a kind of combined type slotting cutter of being made up of knife bar and cutter head.
Background technology
At present; Disclose a kind of like this carbide end mill on the market, its design feature is: be made up of knife bar and cutter head, cutter head comprises many cutting edges; Cutter head one end and outer surface are provided with many cutting edges; Be connected with knife bar at the cutter head other end, cutter head and knife bar connect into an integral body, between cutting edge, also are provided with to hold the bits groove.But because knife bar is longer service life, and cutter head is prone to the tipping damage, and service life is shorter, therefore, is prone to cause waste of material; Again because cutter head and knife bar connect into an integral body, and carbide alloy processes, and shock resistance is relatively poor.
Summary of the invention
The purpose of the utility model provides a kind ofly can save material, combined type slotting cutter that shock resistance is good.
For achieving the above object, the utility model combined type slotting cutter is made up of knife bar and cutter head; Cutter head comprises many blades, and cutter head one end and outer surface are provided with many cutting edges, are connected with knife bar at the cutter head other end; Cutter head and knife bar connect into an integral body; Between cutting edge, also be provided with and hold the bits groove, be provided with screw, do not have an end of cutting edge to be provided with the screw rod that can match with the knife bar screw at cutter head in the center of knife bar one end face.
Between said cutter head of being processed by carbide alloy and screw rod, be provided with the location sleeveless jacket, location sleeveless jacket cross section is rounded, and can match with the location sleeveless jacket of knife bar.
Said knife bar end face of being processed by steel and the axial direction between the screw are provided with the location sleeveless jacket, and location sleeveless jacket cross section is rounded, and can match with the location sleeveless jacket of cutter head.
After adopting this structure; Owing to be provided with screw in the center of knife bar one end face; Do not have an end of cutting edge to be provided with the screw rod that can match at cutter head, when the cutter head loss, can reach quick change and the purpose that continues processing through changing cutter head with the knife bar screw; Process by wolfram steel owing to knife bar again, thus the service life of further having improved cutter.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further to specify.
Accompanying drawing is the main cross-sectional schematic of the utility model combined type slotting cutter.
Among the figure: 1. cutter head 2. is located sleeveless jacket 3. knife bars.
The specific embodiment
The combined type of the utility model shown in accompanying drawing slotting cutter is made up of knife bar 3 and cutter head 1, and cutter head 1 comprises many blades; Cutter head 1 one ends and outer surface are provided with many cutting edges; Be connected with knife bar 3 at cutter head 1 other end, cutter head 1 connects into an integral body with knife bar 3, between cutting edge, also is provided with to hold the bits groove; Center at knife bar 3 one end faces is provided with screw, does not have an end of cutting edge to be provided with the screw rod that can match with knife bar 3 screws at cutter head 1; Between said cutter head of being processed by carbide alloy 1 and screw rod, be provided with location sleeveless jacket 2, location sleeveless jacket 2 cross sections are rounded, and can match with the location sleeveless jacket 2 of knife bar 3; Said knife bar 3 end faces and the axial direction between the screw processed by steel are provided with location sleeveless jacket 2, and location sleeveless jacket 2 cross sections are rounded, and can match with the location sleeveless jacket 2 of cutter head 1.
