Description

Technical Field

[0001] The utility model relates to the technical field of powder metallurgy jigs, in particular to a hard alloy tool bar soft blank supporting jig. Background Art

[0002] Cemented carbide is an alloy material made of hard compounds of refractory metals and bonding metals through powder metallurgy. It has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, and corrosion resistance. In particular, its high hardness and wear resistance remain basically unchanged even at a temperature of 500°C, and it still has a high hardness at 1000°C. Cemented carbide is widely used as tool materials, such as turning tools, milling cutters, planers, drills, boring tools, etc.

[0003] The soft blank of the carbide tool bar made by injection molding technology will bend if it is placed directly on the material plate because it has not been completely cooled. The bending of the soft blank will make it difficult to clamp the soft blank during machining, and the soft blank and the sintering fixture will not fit tightly during sintering, resulting in sintering bending and other problems.

[0004] Therefore, how to solve the above-mentioned deficiencies in the prior art has become a topic to be studied and solved in the present invention. Summary of the invention

[0005] The utility model aims to provide a carbide tool bar soft blank supporting fixture to solve the problem that the carbide tool bar soft blank is bent when being placed.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A carbide tool bar soft blank support fixture, comprising a support plate and a support foot;

[0008] The support foot supports the support plate so that the height of the support plate from the bottom surface of the support foot is greater than the length of the rod body of the soft blank of the tool rod;

[0009] The support plate is provided with a plurality of profiling holes adapted to the head shape of the tool bar soft blank; the tool bar soft blank is suspended on the support plate through the profiling holes.

[0010] 1. A further technical solution is that the connection between the head of the soft cutter bar blank and the bar body is connected by a transition arc, and the shape of the profiling hole is adapted to the arc.

[0011] 2. According to a further technical solution, screw holes are provided on the support plate and the support legs, and the support plate and the support legs are fixedly connected by screws.

[0012] 3. According to a further technical solution, the support plate is a rectangular support plate.

[0013] 4. A further technical solution is that the thickness of the support plate is adapted to the length of the head of the soft blank of the tool bar.

[0014] 5. According to a further technical solution, the length of the support foot is greater than the length of the soft blank of the tool bar.

[0015] 6. According to a further technical solution, the support legs are rectangular plates.

[0016] 7. According to a further technical solution, the contoured holes are distributed in sequence.

[0017] 8. According to a further technical solution, the support plate is a bakelite plate.

[0018] The working principle and advantages of this utility model are as follows:

[0019] The utility model proposes a carbide tool bar soft blank support fixture, which places the injection molded carbide tool bar soft blank in the profiling hole of the support plate, and the tool bar is suspended on the support plate under the support of the profiling hole, which can effectively prevent the tool bar from bending when placed horizontally. After the carbide tool bar soft blank is cooled, it can be degreased and sintered to obtain a carbide tool bar with good straightness. BRIEF DESCRIPTION OF THE DRAWINGS
