Description

Technical Field

[0001] This utility model relates to the field of metal rolling processing technology, specifically to a special cutting tool for turning finished steel sheet pile rolls. Background Technology

[0002] The sheet pile finished product roll is a core component in metal rolling processing. It is mainly used to apply pressure to metal billets to cause plastic deformation, thereby obtaining products of the required shape and size. Its core structure consists of three parts: roll body, roll neck and shaft head.

[0003] A special cutting tool, such as the one disclosed in Chinese Utility Model Patent CN222242800U, includes a milling cutter shank. A milling cutter head is fixedly connected to the surface of the shank. The shank has a through groove and a second mating hole. A guide shaft is provided on the surface of the milling cutter head. A connecting rod is fixedly connected to the surface of the guide shaft. A first mating hole is provided inside the connecting rod. This utility model, by providing a guide shaft at the front end of the milling cutter head, allows the milling cutter to add a guiding device at the front end when machining holes on uneven blank surfaces. Before machining the hole, the guide shaft is inserted into the pre-machined hole. The guide shaft can limit the drift of the cutter, thereby ensuring the roundness of the machined hole. At the same time, the guide shaft can be disassembled through the connection of bolts and nuts. After disassembly, the milling cutter can be used again to ensure that the surface of the machined hole is flat and the pre-machined hole disappears.

[0004] Roll pass cutters (also known as mill pass systems) are core tools used in steel and non-ferrous metal processing for turning roll passes. Their design, manufacturing, and application directly determine the dimensional accuracy, mechanical properties, and production efficiency of the products. Roll passes are the most important part of rolled profiles, and the shape and accuracy of the pass are key to the success of rolled products. Turning the pass is also a difficult point in machining. Due to the complexity of the pass, it is difficult to process on a conventional lathe, and the processing efficiency is low. Utility Model Content

[0005] The purpose of this utility model is to provide a special tool for turning finished steel sheet pile rolls, so as to solve the problems of high processing difficulty and low processing efficiency mentioned in the background art.

[0024] Please see Figures 1 to 5This utility model provides a technical solution: a special tool for turning finished steel sheet pile rolls, including a special tool body 1, a connecting assembly 2, and a reinforcing assembly 3; the special tool body 1 includes a tool holder 101 and a cutting edge 102; the cutting edge 102 is connected to the tool holder 101 through the connecting assembly 2; the tool holder 101 is made of ordinary carbon steel, and the cutting edge 102 is made of W18Cr4V alloy; it is ground with special tools, made according to the hole, and the hole-shaped tools are used in sets;

[0025] The connecting component 2 includes a connecting groove 201 and a connecting block 202; the connecting groove 201 is provided on the handle 101; the connecting block 202 is slidably inserted into the connecting groove 201 through the reinforcing component 3, and the connecting block 202 is fixedly connected to the blade 102; the connecting block 202 is an isosceles trapezoidal structure with a smaller top and a larger bottom.

[0026] This utility model, by setting a dedicated tool body 1 and a connecting component 2, inserts a connecting block 202 into a connecting groove 201 and slides the connecting block 202 in the connecting groove 201 until the side of the connecting block 202 contacts the inner sidewall of the connecting groove 201. Then, the position of the connecting block 202 in the connecting groove 201 is fixed by the reinforcing component 3. Since the connecting block 202 is an isosceles trapezoidal structure with a smaller top and a larger bottom, it can fix the tool holder 101 and the cutting edge 102 in the vertical direction. Compared with the prior art, this utility model has a simple and reasonable structure and ingenious design. It can be used on ordinary lathes, which can improve the accuracy and speed of roll processing, reduce the difficulty of machining, improve production efficiency, and facilitate the disassembly of the tool holder 101 and the cutting edge 102.

[0027] In a preferred embodiment, the reinforcing component 3 includes a rotating groove A301, a rotating groove B302, a rotating column 303, a reinforcing groove A304, a reinforcing groove B305, and a reinforcing block 306; the connecting block 202 has a rotating groove A301; the connecting groove 201 has a rotating groove B302; the rotating column 303 rotatably passes through the rotating groove A301 and contacts the inner wall of the rotating groove B302; seven reinforcing grooves A304 are arranged in a linear array in the rotating groove A301; seven reinforcing grooves B305 are arranged in a linear array in the rotating groove B302; the reinforcing block 306 is fixedly welded to the circumferential surface of the rotating column 303 and rotatably connected to the reinforcing grooves A304 and B305; the rotating groove A301... 01 is a superior arc structure, and the rotating groove B302 is a inferior arc structure. The rotating grooves A301 and B302 form a complete circumferential structure to facilitate the adaptation of the rotating column 303 to the rotating grooves A301 and B302. The reinforcing groove A304 is a superior arc spiral structure, and the reinforcing groove B305 is a inferior arc spiral structure. The seven reinforcing grooves A304 and B305 form a complete spiral structure.

At this time, insert the rotating column 303 into the rotating groove A301 and make the rotating column 303 contact the inner wall of the rotating groove B302. Then, by rotating the rotating column 303, the rotating column 303 rotates in the rotating groove A301 and the rotating groove B302, causing the reinforcing block 306 to slide in the reinforcing groove A304 and the reinforcing groove B305 until the end face of the rotating column 303 contacts the inner wall of the rotating groove A301 and the inner wall of the rotating groove B302. At this time, fix the position of the reinforcing block 306 in the reinforcing groove A304 and the reinforcing groove B305 with screws.
