Abstract

The invention relates to the processing of metals by pressure, in particular, to hand tools. The purpose of the invention is the expansion of technological capabilities. The percussion instrument contains a copus in which the percussion mechanism in the form of a spring-loaded load is located, a mechanism for resetting the cutting tool in the form of a guide rod with a thrust flange and a two-armed lever with a pawl mounted with the ability to interact with the load pins. There is also a cutting tool attached to the free end of the guide rod, and a mechanism for clamping and feeding the material to the cut. By means of a two-armed lever, the load is transferred to the lowest (operating) position. At the same time, the guide rod moves downward under the action of the spring. The end of the load moves the clamp mechanism of the clamp and feed. The material being cut is moved in the direction of the cutting tool by the feed amount. With the further movement of the two shoulders of the lever his dog jumps off the pins of the load. The latter under the action of the springs strikes the thrust flange. The rod is moved upwards and the cutting tool produces metal removal by a predetermined amount. 3 il.

Description

The invention relates to the processing of metals by pressure, in particular to a manual tool.

The aim of the invention is to expand the technological capabilities of the percussion instrument.

1 shows a percussion instrument, a general view; FIG. 2 is the same, section A-A in FIG. on fig.Z - the same, section bb in fig „1.

The percussion instrument includes a housing 1 with a fixed lever handle 2 and a fork 3 o Glass 4 closes the housing from the non-working end. In the housing 1), a sliding seat 5 with a stop flange 6 is also movably mounted a gasket 7. The load 8 is mounted for movement on the rod 5 and is spring-loaded relative to the housing 1 by springs 9 mounted on the centering pins IO and II. The reset mechanism of the cutting tool

 23 is made in the form of a two-armed lever 12 located in parallel

. the axes of the guide rod 5 The lever 12 is fixed in the fork 3 by means of the axis 13 and the screw 4 "On the lever 12, the doggie 15 is fixed by means of the axis I6 and the spring 17. The diplear lever 12 is spring-loaded 18, and the doggie

15 is installed with the ability to interact with the pins 19 of the load 8, the Guide rod 5 is spring-loaded through a spring 20 placed between the support nut 21 and the pin 22. The cutting tool 23 is rigidly fixed to the end of the guide rod 5. From the side of the cutting tool on the body 1 by means of nuts 25, a bracket 24 is fixed, on which a feed mechanism and a clip of the material being cut are mounted in the form of a rod 26, a spring-loaded spring 27, about a rack 28 and a gear wheel 29 placed on the nut 30 and kinematically associated with second ratchet means 31, vsholnennoy in two parts, the spring-loaded by a spring 32. Fastening. gear 29 on nut 30 and adjustment of the ratchet coupling 31 is carried out by means of a threaded rod 33. Handle 34, rigidly connected to nut 30, is used to pre-set the material to be cut with respect to the cutting edge of the cutter 23. The material feed and clamp mechanism includes also the lead screw 35, the feed amount adjustment handle 36, the carriage 37 with the presser 38, located in the guides 39. The presser 38 is fixed on the carriage. 37 by means of the axis 40 and the spring 41. The sleeve 42 provides for the installation of the nut 30 in the arm 24 "

Percussion instrument works as follows about

By means of the handle 36, the feed rate of the material being cut is set to 43. By rotating the handle 34, the carriage 37 is clamped along with the material being cut until the latter is in contact with the cutting edge of the cutting tool 23. By means of the double-arm 12, the load 8 is moved to the lowest (working) position At the same time, the guide rod 5 also moves downward under the action of the spring 20, and the end face of the load 8 moves the feed box 26, while

the material being cut is moved in the direction of the cutting tool by the feed amount. Upon further movement of the two shoulders I2, his dog 15 jumps off the pins 19 of the load 8, which under the action of the springs 9 strikes the thrust flange 6. The rod 5 moves upwards and the cutting tool 23 makes removal of the metal by a specified amount. Then the cycle of operation is repeated.
