A file (1) for producing an uneven contour, in particular with a transverse curvature on a workpiece (11), comprises a longitudinal axis (3), at least one file element (5, 6) with an abrasive machining surface (8) and a depth stop element (7) with a non-abrasive sliding surface (9), wherein the at least one file element (5, 6) and the depth stop element (7) are arranged next to each other in a plane oriented perpendicular to the longitudinal axis (3).

A tool is provided to facilitate user use. The tool includes a handle defining a channel and including a shaft extending therethrough, a tool member rotatably mounted on the shaft and rotatable between an open position in which the tool member extends from the handle and a closed position in which the tool member is folded into the channel defined by the handle, a tool member magnet carried by the handle and configured to exert a magnetic force biasing the tool member to the closed position, a tool lock carried by the handle and configured to engage the tool member in the open position and resist rotation thereof to the closed position, and a first tool lock spring defining an opening through which the shaft extends, the first tool lock spring extending between a first spring portion and a second spring portion and mounted on the shaft such that the first spring portion receives the tool member magnet and is operatively engaged with the handle, the second spring portion being operatively engaged with the tool lock and exerting a biasing force on the tool lock to urge the tool lock into engagement with the tool.

A roller file capable of prompt chip removal, comprising: a file (1), a file connecting base (2), a rolling assembly (3), and a chip removal assembly (4). A through-hole is provided on a head end of the file (1) and is used to mount and fix the file on the file connecting base (2). The rolling assembly (3) is mounted at a front end of the file connecting base (2), and is provided with a roller (33) and a handle coupling member (32). The handle coupling member (32) is coupled to a handle to form, together with a file handle at a tail end of the file (1), a two-point gripping structure. The roller (33) is used for forming a rolling support point at the head end of the file (1). The chip removal assembly (4) is installed on the file (1). During filing, the chip removal assembly (4) is accommodated at the head end of the file (1), and during cleaning, the chip removal assembly (4) moves linearly along a file tooth surface of the file (1) to clear iron chips and impurities. The provision of the two gripping points and the rolling assembly improves filing quality. The chip removal assembly enables prompt clearing of iron chips from the file teeth, thereby improving filing efficiency.

This utility model discloses a file for grinding the outer surface of a circular steel pipe, comprising a file body and a first handle. The file body includes a first blade, a second blade, and a third blade, which are fixedly connected in sequence. The first and third blades are straight files, while the second blade has a semi-circular design. The first handle is fixed to the end of the first blade away from the second blade. The advantages of this utility model are: its simple structure and ease of implementation; it avoids altering the shape of the circular steel pipe during grinding, thus improving grinding quality; and the use of the first and third blades to clean surfaces that are difficult to clean increases grinding speed and improves work efficiency.

A portable processing tool for temporarily replacing the steam seal tooth of a steam turbine product and a use method, relates to the steam turbine processing technical field. In order to solve the problems of poor portability, low processing precision, insufficient efficiency, lack of universality and other outstanding problems in the existing steam seal tooth processing replacement mode, which cannot effectively meet the efficient and accurate operation requirements of the steam turbine site temporary replacement of the steam seal tooth, and the replacement cost is higher. In the process of use, the interval between the two positioning wheels on the right and left of the positioning wheel adjusting block is adjusted according to the interval between the adjacent blades, and the groove of the pulley is ridden on the steam seal piece at the same time, the front and rear pulleys are required to be connected with the body of the steam seal piece to be processed, then the adjusting screw is adjusted, the cutter head of the rotating file is contacted with the steam seal piece, and then the feed amount of the cutter head is set and adjusted through the adjusting screw, so that the steam seal tooth of the steam seal piece can be milled. The present application is suitable for replacing the steam seal piece in the steam turbine.
