The present invention relates to a multi-piece clamping unit (28) for a stretching device (10), the clamping unit having a main component (32) and at least two guides (34). The main component has a base (36) and a clamping device (30) for clamping a material web (12), and each guide has a base (42) and at least one guide element (44) for guiding on a track (17) of the stretching device. The bases of the guides and the bases of the main component are manufactured as separate components and fixed to each other, the bases of each guide and the base of the main component are made of metal and manufactured by casting, the clamping unit has a main direction, and the bases of each guide are fixed to the main component by means of a threaded part of the clamping unit extending parallel to the main direction. Furthermore, the present invention also relates to a stretching device.

The present invention relates to a method for producing an electromagnetic wave-shielding material and an electromagnetic wave-shielding material produced thereby, the method comprising: a liquid metal particle fragmentation step for fragmenting, using an ultrasonic homogenizer, liquid metal particles included in a liquid metal solution in which a liquid metal and a solvent have been mixed; a pretreated liquid metal production step for obtaining a pretreated liquid metal in which the liquid metal particles have been fragmented after removing the solvent of the liquid metal solution in which the liquid metal particles have been fragmented; a liquid metal composite production step for obtaining a liquid metal composite solution by mixing the pretreated liquid metal with a base resin solution; a liquid metal film production step for producing a liquid metal composite film by applying the liquid metal composite solution to a flexible sheet provided with a mask and drying same; a liquid metal activation step for activating a liquid metal by applying acoustic energy to the liquid metal composite film; and an electromagnetic wave-shielding material production step for producing an electromagnetic wave-shielding material by transferring the liquid metal composite film in which the liquid metal has been activated onto a base film.

A method for producing a metal body (10), in particular a housing part, wherein the metal has a melting temperature (Ts) and an evaporation temperature (Tv), and in a step (S10) the body (10) is formed, and a first microstructure (13) is formed during the forming of the body (10), and a surface (16) is created by forming the body (10) which has a roughness (Rz1), and the surface (16) is treated in a further step (S13) at least one surface area by means of an energy beam (22), characterized in that in a further step (S30) the surface area is heated by the energy beam (22) in such a way that the metal of the body (10) immediately adjacent to the surface area is melted by locally increasing the temperature (TM) of the metal, and thereby a roughness (Rz2) of the surface area is produced which is lower than the roughness (Rz1) produced by the forming.

Provided is a counterweight screw, which includes a screw body and a counterweight block that can be embedded in or separated from the screw body. A density of the counterweight block is greater than that of the screw body. An outer circumference of the screw body is provided with external threads, and the external threads are arranged around a circumference of the screw body. The screw body has a non-circular recess, and the counterweight is embedded in the recess. The counterweight block can play a role in weight distribution, and the counterweight screw does not need to be made of high-density rare metals as a whole, thereby greatly reducing costs. There is no need for complex processing of the counterweight block, and the processing of the screw body will not cause excessive damage to the cutting tool, thus simplifying the processing technology.

This utility model discloses a rapid cooling device for die-cast aluminum alloy shells, belonging to the field of metal manufacturing. The rapid cooling device includes a liquid storage tank, a feeding plate fixed to one side of the top of the tank, a first guide plate fixed to one side of the feeding plate, and a second guide plate slidably connected to one side of the first guide plate. The liquid storage tank is equipped with a lifting assembly for moving the second guide plate up and down. A spray assembly is provided on the first guide plate, and multiple push rods, each with a Z-shaped structure, are equidistantly arranged laterally between the spray assembly and the first guide plate. The liquid storage tank is equipped with a control assembly and a drive assembly, the control assembly driving the multiple push rods to rotate synchronously. This utility model uses multiple push rods to push the workpiece onto the first and second guide plates, achieving continuous cooling of the die-cast aluminum alloy shell workpiece, reducing manual intervention, improving production efficiency, and making it more suitable for mass industrial production.

The application relates to the field of metal manufacturing, and discloses a refining furnace for metal manufacturing, which comprises a moving table, a refining furnace, pulleys, supporting arms and a supporting platform; the refining furnace is arranged on the top of the moving table; the pulleys are arranged at the bottom of the moving table in a rotating mode; the lifting assembly is driven to descend by the driving assembly, and the scraping assembly is simultaneously rotated, so that the lifting assembly sends the scraping assembly into the refining furnace, the rotating scraping assembly scrapes off the adhered impurities in the refining furnace, the impurities and metal are removed from the furnace wall, the space in the refining furnace is prevented from being reduced due to the solidification of the impurities and metal, and the staff does not need to clean the furnace, so that the staff feels comfortable.

The utility model relates to metal manufacturing technical field, and disclose a kind of cutter clamping device for metal manufacturing, square tool rest assembly, including square tool rest base, set on the auxiliary assembly of square tool rest base;Auxiliary assembly, including the lifting plate of sliding installation in the inside of square tool rest base, the guide slider of setting in the four around of lifting plate, and the side baffle of fixed installation in the end of guide slider, the side baffle and square tool rest base four around mutually adhere, the auxiliary assembly still include knob of rotation installation in the side of square tool rest base.This cutter clamping device for metal manufacturing, through auxiliary assembly, set the side baffle of lift, since side baffle adhere square tool rest base, lathe tool side portion tightly adhere side baffle and place, it can be explained that lathe tool has not deviated, need not to adopt other tools to determine the position of lathe tool, save the time of searching tool, and side baffle can be reset downward, without affecting lathe tool normal feed.
