The present invention is related to a tool head for chip removing metal machining tools having a cutting insert (3), comprising a basic holder (1) and an insert holder (4) connected therewith, which in the front portion thereof is formed with an insert pocket (7), which is formed between a lower support part (6) and an upper clamping portion (5). The upper clamping portion (5) is actuatable by means of a press arrangement into clamping surface engagement with the cutting insert (3), which is insertable into the insert pocket, the tool being formed with a slot (20) spaced-apart from the insert pocket. The press arrangement comprises a clamping screw (19), which is received in a bore (15) in the basic holder, and a nut roll (11a) adapted to receive the clamping screw, the nut roll being received in a recess (10a) in the basic holder. The recess (10a) is oriented perpendicularly to the longitudinal direction of the cutting insert and the insert pocket. Upon co-operation with the clamping screw (19) during tightening of the clamping screw, the nut roll (11a) is adapted to be imparted movement substantially in the axial direction of the clamping screw radially outwards, such that the nut roll is displaced into said slot (20) and thereby accomplishes such a deflection of the upper portion of the holder that a clamping of the cutting insert (3) is accomplished by this deflection. <IMAGE>

The invention relates to a deoxidation and drying integrated purifier, comprising an external cylinder and an internal cylinder, wherein a filling region is arranged in the internal cylinder and is divided into an upper layer and a lower layer, the upper layer is filled with deoxidant, reproducible silica gel is filled in the upper part of the lower layer, a molecular sieve is filled in the lowerpart of the lower layer, a tube plate arranged above the internal cylinder is welded with an electric heating element protective bushing and a temperature measurement element protective bushing, the electric heating element protective bushing and the temperature measurement element protective bushing extend into the filling region in the internal cylinder, an electric heating element is installedin the electric heating element protective bushing, a temperature measurement element is installed in the temperature measurement element protective bushing, a working gas inlet is arranged at the upper part of the side wall of the external cylinder and is communicated with the upper layer of the filling region of the internal cylinder, and a working gas outlet is arranged at the lower part of the side wall of the external cylinder and is communicated with the lower layer of the filling region of the internal cylinder. The device integrates the functions of deoxidation and drying, simplifies a process flow of a hydrogen purification system and supplies the technical support to safe, stable and continuous running of the hydrogen purification system.

The invention discloses a floating gravity support device at the end of a guide slip shoe of a coal cutter. The floating gravity support device comprises a guide slip shoe (10) and gravity support hydraulic cylinders (4), wherein the guide slip shoe (10) slides in a walking pin row (9); a hydraulic cylinder fixing seat (3) is composed of walking parts, a connection block (11) and an extension section (31) of the connection block (11); the walking parts are arranged on two sides of the walking part housing (1); the connection block (11) is connected with a coal cutter body; the upper ends of the gravity support hydraulic cylinders (4) are respectively arranged on two sides of the hydraulic cylinder fixing seat (3) through hinges (2); support slip shoes (8) are also arranged on two sides of the guide slip shoe (10), and slide on the walking pin row through the support slip shoes; the upper ends of the support slip shoes penetrate through the guide slip shoe and are connected with the lower ends of the gravity support hydraulic cylinders. According to the floating gravity support device, walking wheels are shared or even replaced with the floating gravity support device to support the gravity of the coal cutter; the contact stress between a transmission wheel and a walking wheel and between the walking wheel and a pin tooth is reduced, so that the plastic deformation of various wheel contact surfaces and meshing wear of various wheels are reduced; and the service life of the walking wheels is prolonged.

A printing machine in which the automation of the replacement of the barrier plate is easily performed, and in which further automation of replacement procedure, simplification of replacement procedure, and reduction of time required for replacement procedure are achieved is provided.The printing machine comprises an ink fountain member 2, an ink fountain roller 3, a pair of barrier plates 53 attracted to the fountain-forming face 37a of the ink fountain member 2 and the outer peripheral surface of the ink fountain roller 3 by a permanent magnet, and a barrier plate replacing device 85. The barrier plate replacing device 85 comprises a fountain-member turning device 36, a barrier plate stopper 110 for stopping the barrier plate rotated with the ink fountain roller 3 away from the fountain-forming face 37a by the turning of the ink fountain member 2 and turning the barrier plate in a direction away from the outer peripheral surface of the ink fountain roller 3, a moving body 88 capable of moving above the ink fountain 1 and being raised and lowered, and a barrier plate holding member 91 disposed in the moving body 88 to hold and release the barrier plate 53.

The invention relates to a light-emitting diode (LED) fluorescent lamp with rotatable lamp heads. The LED fluorescent lamp comprises a main body tube, a power plate component and the rotatable lamp heads, wherein a mask is arranged on the upper part of the main body tube; the left and right ends of the main body tube are respectively provided with the rotatable lamp heads; a lamp panel is arranged in an internal cavity of the main body tube; the power plate component is arranged at the upper end of the lamp panel; and the left and right ends of the lamp panel are respectively connected with the rotatable lamp heads through power connecting lines. The LED fluorescent lamp with the rotatable lamp heads has the advantages that: a power supply is directly integrated with the lamp panel by using a circuit; without disassembly of an inductive ballast, which comprises a starter, and an electronic ballast, an old fluorescent lamp can be replaced, so a replacement program is simplified; the two ends of the main body tube are provided with the rotatable lamp heads, so when the LED fluorescent lamp is applied to the conventional fluorescent lamp holder, an angular trouble can be avoided, a single head or double heads can be directly energized, and the LED fluorescent lamp is more convenient for operation; and by design of a spring structure, the LED fluorescent lamp can easily rotate without the help of any tool, so the LED fluorescent lamp can more convenient, more quickly and more safely operate at a high position.
