(54) DEVICE FOR MANUFACTURING NAILS WITH SEPARATELY ATTACHED HAT

one

The invention relates to the processing of materials by pressure, in particular to equipment for the manufacture of nails with a separately attached head.

A device for producing furniture nails is known, comprising a stamp mounted on a frame, having a punch and a die, and a hopper with sharpened rods 1.

However, the performance of the known device is limited.

The closest to the proposed technical essence is a device for the manufacture of nails with a separately attached head, containing mounted on the frame bunkers with trays for nails, shields and caps, a cutter, a plug with a punch and dies, which are placed on the turntable 2.

The disadvantage of this device is low productivity due to the presence of manual labor.

The purpose of the invention. - productivity increase .

The goal is achieved by the fact that the device has a caps feed mechanism and a nail with a washer into the rotary table matrix located under the cutter, consisting of a feeder connected to the cutter with a hose and placed at the outlet of the washer tray, axles and mounted on Ax x 5 frames of spring-loaded cams with contact protrusions, and the mechanism for feeding the caps consists of a split glass and a spring-loaded feeder placed inside the split glass and coaxially with the punch, the Q input of which is connected n yield tray for caps.

The working surfaces of the contact protrusions are located below the axis of rotation of the spring-loaded cams, at least to the height of the washer head.

FIG. 1 shows the device, front view; in fig. 2 - the same, left view; in fig. 3 shows section A-A in FIG. one; in fig. 4 is a section BB in FIG. 3; in fig. 5 shows a section B-B in FIG. 2; in fig. 6 - section G-Y in FIG. five; in fig. 7 is a section d-d in fig. 6; in fig. 8 — node I in FIG. 6

A nailing device with a separately attached head is composed of a stamp 1 with a punch 2 fixed on it, a cutter 3, a nail feed mechanism 4 with a washer, a rotary table cap feeding mechanism 5 with empty dies 7 and dies 8 filled with workpieces and a spring - a spreader 9. On the stamp I a frame 10 is installed with hopper-loading devices 11, 12 and 13 fixed on it with trays 14, 15 and 16, respectively, for nails 17, washers 18, caps 19, and also drive hoppers 20.

Next to die 1, a capacity 21 is set for the finished product.

The nail feed mechanism 4 with the washer in the matrix consists of a hose 22 connecting the slam-shut 3 to the washer feeder, the IMTM. From the frame with the axles 23, the cams 24 with the contact lugs 25 to hold the washer 18 and the springs 26.

The mechanism 5 supply caps consists of a split glass 27 with petals, feeders 28 with springs 29.

The device works as follows.

Nails 17, washers 18, and caps 19 are loaded into the bunker-loading devices 11, 12 and 13. When the drive of the bins 20 is turned on, the workpieces are oriented and filled with trays 14, 15 and 16, which are connected respectively to the cutter 3, the nail feed mechanism 4 and the cap feeding mechanism 5.

When working the punch 2, the latter pushes the feeders-petals of the cup 27 and the cap 19 enters the matrix 8 of the fixed fixed table 6, where there is already a nail 17 with a washer 18. With further progress, the punch 2 lands the nail. Simultaneously with the working stroke of the punch 2, the cutter 3 and the nail 17 are driven through the hose 22, the frame 23 and the cams 24 into the matrix 7 of the previous position of the rotary table 6, capturing the washer 18 under the action of springs 25 and return to their original position.

During the reverse course of the punch 2, the rotary table 6 is unlocked and it is turned one position. When the table 6 is rotated, the spring 9 knocks the molded nail into the container 21 for the finished product.

Then the cycle of operation is repeated.

The proposed design of the device allows to increase labor productivity by more than one and a half times, and therefore, to increase the annual output, reduce its cost, and also improve the working conditions of workers engaged in the manufacture of nails with compacted heads, since it frees them from labor-intensive, little ° productive and monotonous labor.
