Abstract

The utility model relates to a mechanical clamping-type turning tool with a rubbing plate-shaped blade, which can be mounted on a common or numerically controlled lathe saddle for use. The turning tool comprises a cutter body which has a main cutting edge angle of 90 degrees, a front rake of 26 degrees, a main bottom rake of 6 degrees and a cutting edge inclination angle of 4 degrees; and when the front rake face of the carbide blade is pressed by a pressing plate, the two bonding surfaces are engaged with identical tooth shapes and tooth pitches. When the turning tool is used for cutting various brittle metals, the cuttings are broken in the length of 15 mm to 35 mm and in the shape of helix, so that an operator is avoided from being burned by the cuttings and the assembly and disassembly of the cutters and the cleaning of the machine tools are convenient and labor-saving.

Description

Machinery clamping type washboard lathe tool

Technical field

The utility model relates to a kind of mechanical clamping type washboard lathe tool, particularly a kind of can be installed in common or the numerically controlled lathe knife rest on, cut all kinds of brittle metal materials and make smear metal become the washboard lathe tool of short spiral shell web-like.

Background technology

When the operator cuts all kinds of brittle metal material on common or numerically controlled lathe; always to and put on safety glasses with protective baffle plate; in case the chip skin ambustion that disorderly flies, especially when the lower brittle metal material of some fusing points of processing, more to strengthen protection to the operator.Every day, the chip that all is difficult to will splash in was everywhere cleaned out when safeguarding lathe at end-of-job, this traditional mode of operation, the environmental sanitation around the also influence of always wasting time and energy.

Summary of the invention

The purpose of the present utility model will overcome above-mentioned drawback exactly, provides a kind of simple in structure, and is easy to operate and the time make chip be transformed into short spiral shell web-like in cutting to fracture, thereby reaches the safety mechanical clamping type washboard lathe tool of environmental protection again.

The technical solution of the utility model is as follows: a kind of mechanical clamping type washboard lathe tool, and can be installed on the knife rest of common or numerically controlled lathe and use, it comprises that cutter hub has 90 ° of tool cutting edge angles, 26 ° of anterior angles, 4 ° of cutting edge inclinations and and 6 ° of primary clearances.Described pressing plate is compressing the rake face of carbide chip, and two seal faces are identical profile of tooth and tooth pitch engagement.Make to have 6 ° and 4 ° of inclined-planes above the described edge bearing.

Described carbide chip major flank makes 32 °, makes it to form 26 ° of anterior angles with edge bearing applying back.

The utility model is pressed in carbide chip on the edge bearing of cutter hub by pressing plate, makes it to be 90 ° of tool cutting edge angles, 26 ° of anterior angles, 6 ° of primary clearances and 4 ° of cutting edge inclinations, and in cutting, smear metal remains on that 15～35mm is long to be the spiral shell web-like and to fracture.

The specific embodiment

Below in conjunction with concrete diagram, further set forth the utility model.

Shown in Figure 1, for the utility model comprises cutter hub 4 is made 90 ° of tool cutting edge angles, 26 ° of anterior angles, 6 ° of primary clearances and 4 ° of cutting edge inclinations, size 100x12x8mm, the trade mark is YG6 carbide chip 3 and pressing plate 2, its two seal face is cut into identical 120 ° of profiles of tooth and 1.5～3mm tooth pitch with line, be pressed on pressing plate 2 and M6 screw 1 on the edge bearing 6 of cutter hub 4,, can control its footpath of chip-flowing and assurance, axially not be shifted owing to make 4 ° and 6 ° of inclined-planes above 6.After 3 wearing and tearing, unclamp 1 and can constantly extend the blade long service life forward.3 major flank is made 32 °, makes the utility model form 26 ° of anterior angles and 6 ° of primary clearances.When cutting metal materials such as all kinds of cast irons, cast aluminium, crisp brass and oxygen-free copper, adopt u=60～80m/min, f=0.10～0.25mm/r, Pa=4～10mm, because 3 rake face is a washboard-like, so can form the constantly positive and negative value cutting edge inclination of variation, thereby increase the true rake of cutter, do not cause chip curling and cracked and keep that 15～35mm is long to be the spiral shell web-like and to fracture.

Claims

1. mechanical clamping type washboard lathe tool, be installed on the knife rest of common or numerically controlled lathe and use, a kind of mechanical clamping type washboard lathe tool, comprise that there are 90 ° of tool cutting edge angles, 26 ° of anterior angles, 6 ° of primary clearances and 4 ° of cutting edge inclinations in cutter hub front end left side, it is characterized in that the carbide chip rake face when being compressed by pressing plate, both seal faces are identical profile of tooth and tooth pitch engagement.

2. mechanical clamping type washboard lathe tool according to claim 1, it is held and levies is that described carbide chip rake face is meshed with pressing plate and is 120 ° of profiles of tooth and 1.5～3mm tooth pitch.
