Abstract

Usage: the invention relates to {technology for the manufacture of watch parts in awning and can be widely used in 1boro-and mechanical engineering. The goal is to increase productivity in the manufacture of watch parts, as well as improve kg of honest parts due to more accurate alignment of parts during sequential processing at technological positions. SUMMARY OF THE INVENTION: in a method for manufacturing watch parts, comprising cutting along a contour and stripping parts with pressing them into a tape, subsequent metal-cutting processing of parts in a tape and knocking them out of the tape: before cutting the parts along the contour, the tape is first crimped in height and at the same time it is drawn by inserting the base pins and punching the working holes on the surface of the parts, with respect to which subsequent processing is carried out at other technological positions. 2 ill.

Description

The invention relates to a technology for manufacturing watch parts, e.g. bridges, in a tape and can be widely used in instrument and mechanical engineering.

There is a known method of manufacturing watch parts (bridges), using which first bridges and pins based on them are assembled separately, and then parts are assembled into assemblies (pins are pressed into bridges).

 The purpose of the invention is to increase productivity in the manufacture of quality parts due to a more accurate alignment of parts during sequential processing at technological positions.

 In FIG. 1 shows the position of the tape in the crimp (precipitation); in Fig.2 - the process of processing the part in the lft is shown.

The tape 1 is placed between the die 2 and the punch 3 of the crimp die. In the die 2, holes 4 are made under the punch w

There are 5 for punching holes 6 in the tape, and there are holes 7 for receiving the base pins 8. The length of the pins 8 is limited by the inserts 9. Processing of the part 10 is carried out at the subsequent processing positions II-IV.

A method of manufacturing watch parts (bridges) is carried out as follows: tape 1 is sequentially (step by step) by a tape drive device (not shown in the figure) is supplied from position I to IV, at which the following transitions are performed:

I - crimping (slugging) of the tape 1 with the landing (drawing) of the pins 8 and punching holes 6 to base parts during subsequent stamping and trimming:

II — blanking of a part with stripping along a contour, pressing into a tape and punching to hold it in the tape;

III - machining of a part by cutting, for example, boring of seats

for other parts, such as screw preparation, stone supports, adjustments, etc. IV - knocking parts out of tape. At position I, the tape 1 is fed between the punch 3 and the die 2, which are then closed and crimped the tape 1 to the thickness required for the manufacture of bridges. In this case, the excess metal of the tape flows, fills the holes 7, forming the pins 8, and at the same time, the holes 6 are punched with the punches 5.

After that, the punch 3 with the matrix 2 is opened, and the tape is moved one (corresponding) step to crimp the tape 1 under the next part 10, the configuration and profile of which is provided by processing at subsequent IHV positions, while the parts are based on earlier (on I position) prepared base pins and holes).

Thus, the manufacture of watch parts, such as bridges, according to the proposed method provides joint, rather than separate manufacture of bridges and base pins, and also helps to ensure the unity of the bases during sequential stamping and metal-cutting operations when processing parts in a tape.

Claims (1)

As a result of using the proposed method, labor productivity is increased due to the exclusion of machining and mechanical assembly (pressing) of pins into parts (bridges), the quality of parts is improved, since the spread of structural elements (contour, holes) is eliminated by ensuring the unity of the parts database , grooves) along the coordinate axes, which contributes to an increase in the level of collection and interchangeability - 0 of the watch parts, metal utilization rate is improved due to less waste in the chip, Ф rumula of the invention A method of manufacturing watch parts, 5 which consists in cutting parts from a tape along a contour, pressing them into a tape, subsequent metal working, stripping and knocking out of a tape, characterized in that, in order to improve the quality of the parts due to their accurate alignment with successive metal cutting processing at several technological positions, preliminarily, before cutting the parts along the contour, the tape is crimped over the thickness of 5, while simultaneously drawing out the base pins and punching the working holes on p the surfaces of each part, and the installation of parts in each technological position is done by arranging 0 base pins in the corresponding holes of the tape.
