Description

The subject of the invention is a device for catching in the upper position a hammer with a chisel of pylon cutting machines.

All previously developed devices for catching the hammer with the chisel of the pylon cutting machines in the top position were not allowed until the end of the issue of raising the hammer at the moment of cutting the notch and automatic support of the caliper in the opposite direction. On heavy machines, the hammer gives 500-600 beats per minute and is under spring pressure up to 1000 kg. Therefore, all lever 11 screw methods of lifting a hammer with rubber shock absorbers, regularly working on small machines from the worker's foot, are not suitable for heavy machines, especially for automatic operation, for a number of reasons: 1) raising a hammer that produces strong blows is very difficult ; 2) a larger load inevitably requires a slow rise of the hammer and the gradual shutdown of the hammer from work, which is reflected at the depth of the tooth at the beginning and end of the notch; 3) structurally, the lifting unit is bulky; 4) rubber under the action of hard blows quickly wear out.

Taking into account these drawbacks, a device is offered for trapping in the upper position of the hammer with a chisel of a pylon cutting machine at the time of the notching.

This device is made in the form of a lever that interacts with an emphasis on the caliper, and the lever is connected by means of a pull and a handle to a slide that is carried by the catcher automatically fed under the hammer clamp when the lever interacts with the emphasis on the caliper.

FIG. 1 shows the proposed device B longitudinal section; in fig. 2 - partly according to arrow A.

During the notching, the caliper of the cutting machine moves along its guides from left to right. By the end of the notch, the movable stop 5 rests against the tail of the lever / catcher and turns around its axis counterclockwise. The lever /, turning, will turn the handle 3 around the axis 7 by means of the ty 2. The handle 3 with its number 62291-2 -

With a rotary shoulder, the pot no slider 8 from left to right, as a result of which the firing pin catcher 4 will go under the edge of the hammer strap when the latter is in the upper position. The hammer will remain in limbo, slightly startled by a rotating eccentric. The light vibration of the hammer allows the striker to move under the hammer clamp, as well as out of it during the start of the hammer. For a more energetic entry and exit of the catcher’s striker, as well as for fixing it in the working and idle position, in order to prevent accidental movements of the striker, the design provides a latch 9 with a spring 10.

The cage of the catcher 4 for ease of adjustment to the desired clearance has a smooth turnkey face. The hex head is hardened to reduce wear and tear in operation. In addition, for the same purpose, a Kalena interchangeable plate 6 is provided on the hammer clamp.

The hammer is put into operation by the same levers, but in the opposite direction, with the end of the lever acting on the tail of the lever /.
