Description

Forming groove cutter

Technical Field

The utility model relates to a shaping slotting tool belongs to cutter technical field.

Background

The slotting cutter is suitable for processing a mould required by the injection molding of the mobile phone resin shell. Currently, the machining method of the die is to cut with a super-hard alloy grooving cutter while the die is still soft, and then to perform quenching treatment for improving wear resistance. However, a slight dimensional error occurs due to the influence of the heat treatment, and therefore, finishing is performed thereafter using a cemented carbide tool. Most of common slot cutters only have one radian, and most of cutter teeth only have one, if a plurality of notches are required to appear on a workpiece, the slot cutters are required to be repeatedly operated for many times, so that the processing time of the workpiece is prolonged, and the processing efficiency is reduced.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defect that exists among the background art, the utility model provides a technical scheme that its technical problem adopted is: the utility model provides a shaping slotting tool, includes handle of a knife, clamping plane and tool bit, be equipped with clamping plane on the side of handle of a knife, the bottom sprag portion of handle of a knife is fixed with the tool bit, the below of tool bit is equipped with a plurality of sword teeth, and the distance between two adjacent sword teeth is 0.76 millimeters, the sword tooth height of sword tooth is 0.4 millimeters.

Preferably, the length of the left side distance from the cutter head to the left side of the supporting part is 3.65 millimeters, and the length of the right side distance from the cutter head to the right side of the supporting part is 1.83 millimeters.

The radius of the circular arc formed between two adjacent cutter teeth is preferably 0.2 mm.

The preferred number of teeth is 10.

The utility model discloses a shaping groove sword is equipped with the clamping plane on the side of this shaping groove sword's handle of a knife, and the design of clamping plane is favorable to the tight fixedly of quick clamp of groove sword, and the bottom supporting part of handle of a knife is fixed with the tool bit, and the design of supporting part makes the fixed more stable of tool bit, and the below of tool bit is equipped with a sword tooth, and the design of a plurality of sword teeth makes can once form a plurality of trench, has saved groove sword repetitive operation's time. In a word, this shaping groove sword structural design is reasonable, and is high to the machining efficiency of work piece, can once form a plurality of trench, is fit for using widely.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. The attached drawings are simplified schematic diagrams, and merely illustrate the basic structure of the present invention in a schematic manner, and thus show only the components related to the present invention.

In a first specific embodiment, please refer to fig. 1-4, a grooving tool includes a tool holder 1, a clamping plane 2 and a tool bit 4, the clamping plane 2 is disposed on a side surface of the tool holder 1, the tool bit 4 is fixed to a bottom supporting portion 3 of the tool holder 1, a plurality of tool teeth 5 are disposed below the tool bit 4, a distance between two adjacent tool teeth 5 is 0.76 mm, a height 9 of the tool teeth 5 is 0.4 mm, a distance from the tool bit 4 to a left side 6 of the supporting portion 3 is 3.65 mm, a distance from the tool bit 4 to a right side 7 of the supporting portion 3 is 1.83 mm, a radius of an arc 8 formed between two adjacent tool teeth 5 is 0.2 mm, and the number of the tool teeth 5 is 10.

The utility model discloses a shaping groove sword is equipped with clamping plane 2 on the side of the handle of a knife 1 of this shaping groove sword, clamping plane 2's design is favorable to the quick clamp of groove sword to be tight fixed, the bottom supporting part 3 of handle of a knife 1 is fixed with tool bit 4, the design of supporting part 3 makes the fixed more stable of tool bit 4, the below of tool bit 4 is equipped with 10 sword teeth 5, the design of a plurality of sword teeth 5 makes can once form a plurality of trench, the time of groove sword repetitive operation has been saved. In a word, this shaping groove sword structural design is reasonable, and is high to the machining efficiency of work piece, can once form a plurality of trench, is fit for using widely.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications can be made without departing from the scope of the invention.
