Description

A special cutting knife with a knife seat for rolls

technical field

The utility model relates to a special cutter for rolls with a knife seat, which belongs to a kind of cutter for mechanical processing.

Background technique

The shape and size of the rolls are generally large, and some rolls need to be machined with deep grooves. When processing deep grooves on the surface of large rolls, the handles of the turning tools (also called grooving knives or cutting knives) used are very long. When used, the handles of the turning tools are directly clamped on the tool holder of the lathe. During the machining process, the turning tool vibrates, swings, and the tool handle is bent and deformed, which makes the cutting inaccurate, the size of the cut groove is unqualified, and the production efficiency is reduced. This has become a common technical problem in this field.

Utility model content

The technical problem to be solved by the utility model is: to provide a special cutting knife with a knife seat for rolls, which can effectively enhance the rigidity of the cutting knife during the grooving process, reduce the deformation of the cutting knife, and improve the processing efficiency. By using the special tool seat for the roll cutter, the swing of the cutter during the cutting process is effectively prevented, the clamping steps of the cutter are simplified, and the processing stability is improved.

In order to solve the problems of the technologies described above, the technical solution adopted by the utility model is:

A special cutting knife for rolls with a knife seat, comprising a knife body composed of a knife bar and a knife head, the knife bar of the knife body is mounted and clamped in a knife seat fitted and fixed with a knife rest of a lathe, the The tool seat includes the main body of the tool seat for placing the knife bar and the bolts for clamping the knife bar. The main body of the tool seat includes a deep groove composed of a thin side wall, a thick side wall and a connecting part. The knife bar is placed in the deep groove, and the thin side wall A bolt hole is provided, and the bolt passes through the bolt hole to press the roll cutter against the thick side wall.

There are at least three bolt holes and bolts. The deep groove is a U-shaped groove.

Owing to having adopted above-mentioned technical scheme, the technical progress that the utility model obtains is:

1. The special tool holder for the roll cutter can be widely used in the deep groove processing of the rough turning process of the roll, and the processing efficiency is high. The utility model can effectively enhance the rigidity of the cutting knife in the roll grooving process and reduce the deformation of the cutting knife. By using the special tool seat for the roll cutter, the swing of the cutter during the cutting process is effectively prevented, the clamping steps of the cutter are simplified, and the processing stability is improved.

2. The special cutter for rolls is easy to manufacture, and waste cutter bars can be used as raw materials for processing, which is convenient for materials and low processing cost.

3. The special cutter for rolls is light in weight and easy to install and disassemble. Just install and clamp the cutter holder on the tool holder of the lathe. When the cutter needs to be sharpened or the extension length of the cutter needs to be adjusted, just loosen the bolt directly. .

4. The special cutter for rolls is easy to use, can meet the requirements of rough turning and head cutting, and has a good effect.

5. There are three bolts, which can be adapted to the effective positioning of different cutters.

6. The deep groove is a U-shaped groove, and the structure of the special cutter for the roll is more stable, and it is easy to process and has a long service life.

Detailed ways

A special cutter for rolls with a knife seat of the utility model includes a cutter body and a knife seat, as shown in the figure. Cutter body is made of cutter bar 6 and cutter head 7, and cutter bar 6 is installed and stuck in the knife seat, and knife seat is assembled and fixed on the knife rest of lathe. The tool seat includes a tool seat body for accommodating the tool bar 6 and a bolt 8 for clamping the tool bar. The knife seat main body is an elongated rectangular iron block, and the knife seat main body includes a deep groove 4, and the deep groove 4 is generally opened into a U-shaped groove. The deep groove 4 is composed of a thin side wall 1, a thick side wall 2, and a connecting part 3. The cutter bar 6 is placed in the deep groove 4. The thin side wall 1 is provided with a bolt hole 5, and the bolt 8 passes through the bolt hole 5 to cut the roll into the knife. Pressed against the thick side wall 2. There are at least three bolt holes and bolts.

The main body of the knife seat is the positioning and force-bearing part of the cutter, and strength analysis is required during design. Since the cutter body is manufactured by forging instead of turning, the structural size of the cutter body itself is poorly controlled. Therefore, when designing the groove width of the cutter holder body, an appropriate margin should be considered to ensure Bolt clamping on side panels can be achieved.

The special knife seat for the roll cutter presses the cutter on the thick side wall 2 of the deep groove 4 of the knife seat by passing the bolt through the bolt hole 5 on the thin side wall 1, so as to realize the positioning and clamping of the cutter. When grooving, install the special tool holder for the roll cutter on the tool holder of the lathe. By adjusting the position of the special knife holder instead of the cutter, the processing of grooves with different depths is realized, which greatly enhances the tool’s durability. Rigidity improves processing efficiency.

The special cutter holder for the cutting knife has simple structure and convenient operation, can be modified by using the existing waste cutter bar, has low processing cost, and has good prospects for popularization and use on roll lathes. The special tool holder for the roll cutter has been fully promoted on the rough turning machine tool of the fifth branch of Sinosteel Xingtai Machinery Roll Co., Ltd.
