Watchband perforating device capable of adjusting perforating spacing conveniently

Abstract

The invention relates to the technical field of watches, and discloses a watchband perforating device capable of adjusting the perforating spacing conveniently. The watchband perforating device comprises a casing; the top of an inner cavity of the casing is rotationally connected with a transmission screw; the upper part of the transmission screw is fixedly sleeved with symmetrical bevel gears; the right sides of the bevel gears at the top of the inner cavity of the casing are rotationally connected with driving toothed bars; the middle of the inner cavity of the casing is glidingly connectedwith a bearing plate; and a supporting spring is fixedly connected between the bearing plate and the side wall of the casing. According to the watchband perforating device capable of adjusting the perforating spacing conveniently, the transmission screw is driven to rotate in a reciprocating manner through the driving toothed bars by the aid of incomplete gears at the left ends, a threaded casingpipe can drive ejector rod parts to intermittently move up and down, the spacing between ejector rods is controlled through rotation of an adjusting screw in a matched manner, and then an air guidingstrip is arranged between the ejector rods in a matched manner, so that the perforating rate of watchbands is increased, the perforating spacing of the watchbands can be conveniently adjusted, and thecleanness of the watchbands after perforating is guaranteed.

Description

technical field [0001] The invention relates to the technical field of watches, in particular to a watchband punching device for conveniently adjusting the hole spacing. Background technique [0002] With the gradual improvement of intelligent manufacturing technology, the products processed by the product processing and manufacturing industry are becoming more and more detailed, and the quality has changed dramatically. Hole opening processing, when the general strap punching device is in use, because it can only punch one hole for a single strap at a time, when processing a large number of straps, it will take a huge processing time, which will lead to punching The processing rate is severely lowered, and because the specifications of each type of strap are different, it is difficult for a single type of punching device to adjust the punching distance. Therefore, for different straps, multiple sets of different punching gaps are required. The strap punching device is like...

[0002] With the gradual improvement of intelligent manufacturing technology, the products processed by the product processing and manufacturing industry are becoming more and more detailed, and the quality has changed dramatically. Hole opening processing, when the general strap punching device is in use, because it can only punch one hole for a single strap at a time, when processing a large number of straps, it will take a huge processing time, which will lead to punching The processing rate is severely lowered, and because the specifications of each type of strap are different, it is difficult for a single type of punching device to adjust the punching distance. Therefore, for different straps, multiple sets of different punching gaps are required. The watch strap punching device is likely to reduce the practicability, and after the watch strap is opened, there are randomly distributed dander near the hole, and these dander adsorbed on the strap require additional processing in the later stage

[0003] Aiming at the deficiencies of the prior art, the present invention provides a watch strap punching device for conveniently adjusting the hole spacing, which improves the punching rate of the watch strap, can conveniently adjust the hole spacing of the watch strap, and ensures the The advantages of neatness after the hole is opened solve the problems that the general strap punching device is prone to low punching rate, difficult to adjust the punching distance, and additional cleaning is required after the strap is punched.
