SU18429A1 - Nut press - Google Patents

Description

To eliminate too fast and uneven wear of the slide and their locking elements in nut presses under the influence of a driving force directed at an angle to the direction of movement of the slide, this kind of press is offered, which has a device between the pressure knuckles and the sled that converts sloping pressure of the knives to the slide into pressure acting only on the axis of the slide.

In FIG. 1 depicts a longitudinal section of the proposed press; FIG. 2 the same, and the plan; FIG. 3-transverse section along the axis of the transfer rods, i.e. on AB, in FIG. one; FIG. 4-cross section in the middle of the sled length, i.e. according to GD in FIG. one; FIG. 5 is a longitudinal section of a modification of the transmission of pressure from the fists.

The proposed device consists of a slide 1 with a punch 5 sliding along the auxiliary board 4 located in the bed 5 and accommodating in itself, separated by the auxiliary board 5 slide 6 with the core 7. The slide 8 is driven by the pulley 8 by means of axes 9 fists 10, 11 and 12; of which two fists 10 11 11 are driven by a nuanson sled, and fist 12 by a sled. Above the end of the sled in the frame on the axis 13, three rods 14, 16 and 16 are loosely mounted, the heads of which are placed between the sled and the fists and facing the sled, the protrusions 17, and the fists-rollers 18.

A modification of this device involves the replacement of a smallpox 13 with a slider 19 moving along a guide 20 (Fig. 5), parallel to the movement of the slide. When the axis 9 rotates, the fists 10, 11 and 12 rotate to stretch the rollers 16 facing them on the levers 14, 15 and 16 or on the overhanging end of the slide 19, move them forward, and with them the slide, and the levers through the axes 16 or the slider, through the guide 20, perceives the component of the fist pressure, which is directed from top to bottom, and the sled is subjected only to the pressure of the horizontal component of the fist pressure, while the rollers 18 contribute to the destruction of friction when decomposing the oblique fist pressure.

The subject of the patent.

1. A nut press with one or several working tool carriers, slides moved by rotating cams, characterized in that there is a rod (14, 1, 6) between one or several cams (10, 11, and 12) and corresponding sleds (1, 6).

15th 16), equatorially on one common axis (IS), perpendicular to the level of dvleniya salazov, nln the sliders (19), using the direction | To (20) parallel to the movement of the sled.

2. In the vdonzkenenne nut press, okharavternzovannogo in paragraph 1, characterized by the fact that the HEAD of the rods (jf4,16,16) ps sliders (19) are equipped with wavelengths E (18) for the perforation of the pressure of the cam.
