Description

Clip-on Bevel Knife with Insert with Twist Cutting Front

technical field

The utility model belongs to the field of cutters for mechanical cutting, in particular to a clamping-type slope cutter with a twisted cutting front blade in the field of mold manufacturing with a demoulding slope.

Background technique

For a product that depends on mold compression molding, injection molding, and stamping molding and requires a mold release slope, it is common to manufacture molds with slopes. The existing tools and methods for processing slopes are: tungsten steel (hard alloy) slope knife, but the cost of tungsten steel slope knife is high, and when processing deeper slope, tungsten steel slope knife is not ideal; HSS (powder metallurgy) white steel slope knife, but HSS white steel slope knife The high-degree knife is easy to wear and has poor durability; the clamping blade performs plane layered processing, that is, the milling depth is 0.5-1mm at a time, and the slope is corrected for the tool, but the processing efficiency is low and the blade is easy to wear; the clamping blade performs plunge milling, The software is too expensive, and the programming is difficult to master; electric discharge machining, which is not feasible for large processing areas and deep slopes.

Contents of the invention

The technical problem to be solved by the utility model is to overcome the problems of high cost and difficult processing of the existing above-mentioned processing slope, especially the processing of workpieces with large area and relatively long slope.

The technical measure adopted by the utility model is to provide a clamping slope cutter with a twisted cutting front blade, which is composed of a cutter bar, a cutter head, and a blade. Both the rod type and the cutter head type have single-layer blades and double-layer blades, as well as clamping ceramic blades that are clamped on the other end of the knife rod or the large end of the cutter head. There are two types of tool holders: straight shank and tapered shank, and the connecting tool holder of the cutter head is tapered shank. The cutter head is composed of a small cylinder, a transitional truncated cone, and a large cylinder smoothly connected. The center of the cutter head is equipped with a tapered hole for the cone connected to the cutter bar to fit and fit precisely. The small cylinder of the cutter head The outer circumference is provided with a cutter head positioning groove which matches the positioning pin on the connecting cutter rod. The other end of the tool bar and the round side of the large end of the cutter head are provided with two 180° opposite "L-shaped" chip removal grooves for clamping the blade. In the "L-shaped" chip removal grooves of the two clamping blades of the cutter bar and the cutter head, there are 1 (single-layer) or 2 (double-layer) screws for screwing in the compression screws for pressing the blades. hole (not shown in the figure). The clamping ceramic blades assembled according to the workpiece shape or processing technology requirements can adjust the two layers of blades to the same slope or different slopes or process one layer directly facing the other layer. The cutting front and main cutting edge of the clamping ceramic insert assembled according to the shape of the workpiece or the requirements of the processing technology are twisted. The ceramic blade is provided with a clamping hole fixed with the cutter head or the cutter bar.

The utility model has the beneficial effect of adopting ceramic blades with low price, high hardness and good wear resistance, which have high durability and stable machining accuracy; The straight surface and the lower blade process the inclined surface. The workpiece with both the straight surface and the inclined surface can be processed at one time by selecting the tool corresponding to the inclination; no matter whether the straight surface or the inclined surface is processed, the two layers of blades can be adjusted to the same feed rate and processing depth. The finishing of the straight surface and the inclined surface is completed at one time, which not only ensures the accuracy but also reduces the cost. The depth of cut can be 3-5mm each time, which greatly shortens the processing time; because the blade is clamped and easy to replace, it can be customized according to different workpieces. Material requirements, different blades are clamped, and one knife is multi-purpose; because the cutting front and the main cutting edge are twisted, the cutting edge gradually cuts into the workpiece during processing, which greatly reduces the cutting force.
