Description

The horizontal horizontal press belongs to the field of mechanical assembly in the machine-building industries, in particular, to devices for assembling interference fit and can be used to press the splined part of the cardan shaft into the cardan shaft pipe.

A device for assembling with an interference fit of male and female parts [RU 2043897 C1, B23P 19/02 (1995.01), 09/20/1995], consisting of a bed, a part of which is a table with T-grooves for fixing (fixing) the corresponding technological equipment . On the upper part of the bed with the help of studs, nuts and a plate having a central landing hole, an electromechanism is installed, which is part of the mechatronic unit of the reciprocating drive. The screw of the electromechanism is rigidly connected to the press-in punch, which has the ability to move only translationally, since it is equipped with a guide key that prevents it from turning about its axis. At the lower end of the punch there is a threaded hole for attaching a replaceable press-in mandrel, which exerts a force on the assembled parts.

The disadvantage of this device is the structural complexity of the used special technological equipment.

A device for assembling parts by pressing [RU 2008162 C1, B23P 19/02 (1990.01), 01/11/1991], including guides fixed on the base, on which a slider is located and a power cylinder rigidly fixed on it, the rod of which is connected with the stop. On the base, a drum is mounted with the possibility of rotation by a dividing mechanism, in the guide holes of which are spring-loaded plungers and mandrels made in the form of punches and bushings covering them. The punches are rigidly connected to the plungers, and the bushings are mounted on the punches movably and spring-loaded relative to them.

The disadvantage of this device is the high metal consumption and design complexity.

Known hydraulic horizontal press for pressing and unpressing products [RU 368 976 C1, V23P 19/02 (2000.01), V30V 9/00 (2000.01), 11/08/1973], containing fixed upper and lower power rods fixed crossbars (racks), in one of which is equipped with working and return hydraulic cylinders, as well as a movable crosshead installed between the cross members (uprights), while the movable crosshead is hollow and equipped with lower support and upper rollers placed in its inner cavity, mounted respectively on the lower and upper sludge rods, wherein the lower rollers are provided with individual drive their movement along the lower thrust force, the upper fixedly secured.

The disadvantage of this device is the uneven distribution of load on the workpiece, deformation, reduced mechanical and operational properties of the parts.

The objective of the utility model is to increase the efficiency of pressing parts in a multinomenclature production, by reducing the complexity of the changeover of technological equipment from one type of assembled parts to another, and the convenience of monitoring the process of pressing, since it is possible to precisely determine and limit, if necessary, the pressing force .

The use of a horizontal hydraulic press allows to reduce the cost of funds when assembling tightened joints by improving the quality of metal processing by pressure, the mechanical and operational properties of the workpieces with the exception of their deformation, increasing the wear resistance and productivity of the equipment due to the uniform load distribution on the workpieces with a certain optimal force .

This is achieved by the fact that to the base plate, to which the supports are rigidly attached, with a movable stop mounted on it with a mandrel made with the possibility of vertical movement, a fixed stop and a movable latch. A hydraulic jack is mounted on the fixed stop, made with the possibility of vertical movement. Holes are made on the base plate for fixing the movable stop and movable latch, depending on the size of the assembled parts. Also, tool boxes are installed under the base plate.

The arrangement and operation of the horizontal horizontal press will be understood from the following description and drawings.

FIG. 1 - hydraulic horizontal press (side view); FIG. 2 - hydraulic horizontal press (top view).

The hydraulic horizontal press consists of a base plate 1 (Fig. 2), to which the supports 2 are fixed (Fig. 1), with a movable stop 3 mounted on it with a mandrel 4 (Fig. 1), made with the possibility of vertical movement, fixed stop 5 and a movable latch 6. A hydraulic jack 7 (Fig. 2) is mounted on the fixed stop 5, which is made with the possibility of vertical movement. Holes are made on the base plate for fixing the movable stop 3 and the movable latch 6, depending on the size of the assembled parts. Also under the base plate 1 installed tool boxes 8.

The hydraulic horizontal press operates as follows (using the example of pressing the splined part of the cardan shaft into the cardan shaft pipe).

The driveshaft is fixed in a horizontal hydraulic press by means of a mandrel 4 (Fig. 2) located on the movable stop 3 (Fig. 1) and a movable lock 6. Depending on the size of the assembled parts, the movable stop is moved through the holes of the base plate 1 (Fig. 2) ) and fixed with bolts. Next, in the pipe of the propeller shaft, the spline part of the propeller shaft is installed and, moving the rod of the hydraulic jack 7, press-fit is performed. Previously, before mounting the rod of the hydraulic jack 7 is installed in the same plane with the axis of the propeller shaft, moving the hydraulic jack 7 along the grooves of the fixed stop 5 (Fig. 1).

The use of a horizontal hydraulic press allows to reduce the cost of funds when assembling tightened joints by improving the quality of metal processing by pressure, the mechanical and operational properties of the workpieces with the exception of their deformation, increasing the wear resistance and productivity of the equipment due to the uniform load distribution on the workpieces with a certain optimal force .
