The inventive device includes a housing in the form of thermally hardened nuts with the notch on the end to lock it in the eye and capture, made in the form of a thermally hardened screw having at one end shaped groove tapering toward the exit to capture the head gate or other device, and a groove at the other end to the pivoted arm. 1 Il. The invention relates to a device for the removal of locking devices, hung on the doors of railway cars and other objects, the establishment of traction 2500-3500 kg this device.A device in mechanical engineering, chemnick for removing parts that contain the holder with clamping rollers for engagement vypressovyvaniem detail, the case with a hole for a bearing and a screw, screwed into the holder to create traction.Known decision was made as a prototype.Technically, the result is the creation of a technical and durable kanstroom the refusal with the development of significant pulling effort to fracture (opening) closures.The invention is explained bellow.Removable device includes a housing 1, a grip 2, the handle 3, the pin 4.The body is made in the form of a nut with a notch 5 at the end of the thread 6 and a handle 7 attached to it.The gripper is a screw profile with radial groove 8, tapering to an outlet at one end, a recess 9 at the other end under the arm 3, the thread 10 and the hole 11 pin 4.The handle is made in the form of a pipe 12 with the procedures established in her earring 13 having a chamfer 14 under the groove 9 of the takeover and the 5 hole under the pin 4.The removable device is used as follows.On a side hinged in the eye of the carriage locking device wear removable groove 8 of the grip 2 and, holding with one hand the handle 3, with the other hand rotate the housing 1 by the handle 7 clockwise to the stop of the housing 1 notch 5 in the eyelet of the car.After fixing the removable device in this position, stop the rotation of the housing 1 and start the rotation of the handle 3 for pipe 12 counterclockwise, pulling this capture 2 shut-off device, is fixed in the groove 8.Developing sufficient force (2500-3500 kg) in the above-described manipulation circuit of the device is about the closing device is opened. Removable device, comprising a housing made in the form of a nut with a handle grip mounted in the housing and is designed as a screw, one end of which is mounted the handle, wherein the other end of the screw is made with shaped groove, tapering to a nearby end, a handle at the first end of the set screw hinge, and at the end nut from the side of the curved groove of the grip made the notch.
FIELD: devices designed for simplifying procedures of assembling/disassembling units.
SUBSTANCE: crank stripper includes cross piece 1 supporting power mechanism in the form of one-way telescopic hydraulic cylinder 2 having thrust rod 3 for shaft of crank 14; mechanism for forced closing of foots having cylindrical discs 8, 9, paired plates 10 and double-arm levers 4,5. One arm is used for engaging with crank; other arm of is cone one and it may rest upon lateral surface of cylindrical disc secured to lateral side of cross piece. Double-arm lever whose arms are mutually inclined by obtuse angle is jointly mounted through paired plates in center of disc. Articulation joint of lever is mounted in edge portion of second lever arm on line of inner surface of first lever arm.
EFFECT: intensified clamping of part by foots, enhanced efficiency, lowered cost price of working operations.
FIELD: machine engineering, namely mechanical strippers.
SUBSTANCE: stripper includes traverse bar with grips, screw having two outer threads with different pitches; main detachable sleeve mounted by thread whose pitch is less than that of said screw; additional threaded sleeve mounted by second thread of said screw; holder embracing both sleeves, fixed relative to them in angular direction and resting by its inner shoulder upon end of main sleeve. Inner shoulder is formed on one end of holder; other open end of holder is arranged in through opening of traverse bar and it is rigidly joined with said bar. Threads of powerful screw have similar sign; additional sleeve has outer flange spaced from open end of holder by interval determined according to relation K = B1(H2/H1 - 1), where K - interval between outer flange of additional sleeve and open end of holder; B1 - displacement (caused by main sleeve) of part stripped by means of stripper; H2 - thread pitch of additional sleeve; H1 - thread pitch of main sleeve. Sleeves are mutually spaced by interval T exceeding value of mutual convergence of sleeves.
EFFECT: simplified usage of stripper.
FIELD: machine building.
SUBSTANCE: invention refers to manual tools and is used for removal of packing plug from channel. The plug consists of an external clutch and an internal core retained in the external clutch. The said removal is performed upon drilling an appropriate blind hole in the core. Device for removal (4) consists of conic punch (15) for forced introduction into core (14) to ensure interference fit between punch (15) and core (14). Further, core (14) is withdrawn from clutch (13); simultaneously core (14) is maintained on punch (15) due to interference fit. Also device for removal (4) consists of facility for clutch catcher (16) designed to catch clutch (13) after removal of core (14) with punch (15) from clutch (13). Clutch catcher (16) and punch (15) are removed from removal channel together with clutch (13) and core (14) maintained on corresponding sections of removal device.
EFFECT: reliable retention of removed part on tool for removal and possibility of its further usage.

SUBSTANCE: invention relates to pressuring by hydraulic device and may be used, in particular, for jointing fitting with tube by pressuring. Proposed device comprises piston and cylinder to act on pressuring jaws. Piston rod is jointed with acting appliances. Adjustable stop is arranged in direction of hydraulic piston travel to set piston extreme position in back stroke. Said stop is arranged outside said cylinder. By varying stop position, pressuring force is carried applied in pressuring. To set pressuring force, pressuring device is set so that pressuring is performed in continuous travel of piston.
EFFECT: expanded performances.

SUBSTANCE: invention relates to method of operating hydraulic press-fitting device, hydraulic press-fitting device with hydraulic pump. Proposed device comprises hydraulic pump, moving part, stationary part and check valve. Moving part moves into press-fitting position on creating pressure in hydraulic chamber. Return spring forces moving part from press-fitting position back into initial position. Check valve closed after pressure drops below preset level due to back flow of hydraulic medium. Means arranged ahead of check valve act on hydraulic medium with check valve open. Said means inhibit hydraulic flow to cause pressure drop to change check valve into closed position.
EFFECT: selective stop of moving part in selected position.

SUBSTANCE: invention relates to press tools. Press-tool for jointing, mainly, tubular billets comprises several press elements articulated like chain links. Press-tool is opened to make the point of closure between two end press elements. At least one of the latter has press jaw holder Press-tool is equipped with manipulator to open press-tool from closed position whereat closure point is, in fact, closed, and to release at least one end press element with shift of press jaw and its release from closed position.
EFFECT: simplified use.
