Description

one

The invention relates to the field of metal processing with pressure and can be used for impact stamp products in the metallurgical and engineering industries.

A portable pneumatic crimper is known, comprising a cylinder with a piston-hammer placed in it, performing a reciprocating motion and acting on a self-aligning stamping head located on one of the ends of the cylinder, as well as a distribution device mounted on the opposite end of the cylinder, including an associated with a pigan source and atmosphere, a control spool, a control spool and a knob. The disadvantages of this glue can be attributed to a large pressing force, necessary for the normal operation of the user, and a reduced efficiency. energy transfer from the striker to the branding head.

In order to reduce the working force and increase the speed energy transfer to stigma; The head, in the proposed consumer, the controlled spool of the distributing device is three-positioned with single-head pneumatic control and spring-loaded from the uncontrolled cavity, which is communicated with the atmosphere by means of axial and radial channels in its body, and the controlled cavity is connected by end and side channels made in the housing of a distributing device, with a control spool, which is rigidly connected with a spring-loaded handle.

FIG. I shown are described:; stamper in the initial position; in fig. 2 - the same, the first working position; on fng. 3 - the same, the second working position.

A portable pneumatic fastener consists of a self-mounted clamp clamp; golozkp 1 with a set of stamps, tsnlnndtsa 2 with the drummer 3 located in the letter, air distribution -1 -1 of the handle 5.

K.Guyuvochnaya goloppi usgapovlsna in rocks Hei part of the cylinder n is equipped with a bottom: oi ;, spring b 6, which is idipram; c / 1 in the stops 7 inlnid1) and 1h eG; ms) in-1NoG1 heads. The front part of the unit is closed with the clamp 9, into which the mark is lined up; l is in the initial position of the knit; With CTOpoiii.i, the air-distributor cylinder is provided with clamps 1C (pa of Fig. 1 conditionally shown with the lock.), Bhsd: 1, in the hammer 11 of the striker, when it turns out to be the most extreme position. The distributor air distributor is equipped with a control 12 and a control 13 cylindrical spools. The controlled spool is made three-way with one-way pneumatic control, for which the uncontrollable cavity using the axial 14 and radial 15 channels in it is connected to the atmosphere, and the controlled cavity is connected with the help of end 16 and lateral 17 control channels in the housing of the distributor 10 a control spool rigidly connected to the handle. The body of the control spool is made up of a radial 18 and an axial 19 hole communicated with the atmosphere. For self-installation in the initial position, the adjustable spool and the handler of the customizer with the control spool are equipped with springs 20 and 21, respectively. The applicator works in the following way. In the off position, the label 20 (Fig. 1) is clamped by the action of the spring 6 against the lid 9, and the handle 5 with the control spool 12 and the control spool 13 are pressed into their edges 25 by the action of the springs 21 and 20. The controlled spool, under the action of its spring, occupies the lowest position due to the fact that the end control channel 16 in this case connects the control spool 12 to the atmosphere. In this position of the controlled spool, air from the line enters the non-working cavity of the cylinder and sets the drummer 3 to the rearmost position, where it is locked with locks 10, and the working cavity of the cylinder using axial 14 and 15 radial channels in the controlled spool communicates with the atmosphere. When working with the applicator, the latter is applied with a stamping head to the marked surface and, by gentle pressure on the handle, the non-working cavity of the cylinder is connected to the atmosphere and the compressed air is fed into the working cavity of the cylinder. In the first working position of the consumer (FIG. 2), a preliminary release of compressed air from the non-working cavity of the cylinder takes place. When the handle 5 is pressed, the lateral control channel 17 of the controlled spool 50 13 communicates with the atmosphere through the radial 18 and axial 19 channels in the control spool 12, and the front control channel 16 communicates with the main, due to which the compressed air enters the control cavity. 55 th spool and moves it up. As it moves, the lower end of the controlled spool opens a side opening in the diffuser housing connecting the control cavity with the side control channel 17, cco6 uciinbi: vi to the atmosphere, and therefore the slide operated upward slide stops. In this position of the scientific research institute of the controlled spool, compressed air is forced out of the non-working 65 5 45 cylinder. With the release of compressed air from the non-working cavity of the cylinder, the locks 10 hold the hammer 3 in the extreme rear position in the case of a horizontal arrangement of the marked surface. When compressed air is released from the cylinder non-working cavity, the stamping head is sunk, compressing the spring 6, under the force exerted on the handle. In the second working position of the consumer (FIG. 3), compressed air is supplied to the working cavity of the cylinder. By further pressing the handle 5, the control spool 12 depresses deeper, causing the side drip 17 of the control to overlap, and the control spool 13 does not move to the extreme upper position, together with the dead cavity of the cylinder and the trunk. Under the action of compressed air, the impactor 3 acquires kinetic energy and strikes the stamping head with a set of stamps. At the end of the stamp, the handle occupies the leftmost position under the action of its springs (Fig. 1). In this case, the control valve under the action of the spring 20 does not move to its lowest position, together the working cavity of the cylinder with the atmosphere, and the non-working one with the trunk. Under the action of compressed air, the drummer moves to the extreme left position and is locked with latches. The proposed stamper cannot be turned on without pressing it to the marked surface, which excludes the possibility of its accidental inclusion in the inoperative position. Invention The portable pneumatic clamper containing a cylinder with a shock punch in it, performing reciprocating motion and acting on a self-aligning glue head. placed on one of the ends of the cylinder, as well as a distribution device mounted on the opposite end of the cylinder, including the size whelping in the housing coupled to the power source and the atmosphere control spool controlled by a spool and a handle, characterized in that, in order to reduce the working efficiency of the force and the Enhance the energy transfer to the stamping head, the controlled spool of the distribution device is three-position with one-side pneumatic ejection and spring-loaded from the inert cavity, which communicates with the atmosphere through the axial and radial channels formed in its body, and its cavity is connected by the end and side channels made in the switchgear housing, with a control spool rigidly connected to a spring-loaded handle.
