Abstract

The utility model relates to a bearing printing copper letter plate with printed letters, characters on the end surface of the bearing, wherein terrace dies of letters, characters made of thin copper plate are vertically embedded and welded on a copper foundation pile (2) which is fixed on a die body (3) made of plastic, the die bodies each are connected by plain conductors (4), and sealed by insulating resin. The utility model has the advantages of simple and reliable structure, clear printed characters and patterns. The height of terrace die of letters, characters of the structure is improved about ten times than the height of the terrace die which is made by the re-corrosion of the traditional photographic forming, so the utility model is of durability, uneasy abrasion, and the printed letters and characters which are used repeatedly can maintain original and clear, hence a good tool of printing bearing.

Description

Bearing is printed the copper letter stencil

One, technical field:

The utility model relate to a kind of on bearing face a kind of printing tools of letter punch, literal, specifically a kind of bearing is printed the copper letter stencil.

Two, background technology:

At present, domestic technology at letter punch, literal on the bearing face is generally all taked by photographic negative letter, literal sensitization to be formed on the monoblock copper coin earlier, corrode then and make the copper letter stencil, on the bearing end, print at last, its shortcoming is: the letter that this copper letter stencil is made, the not enough 0.4mm of the punch height of literal, and have gradient (up-narrow and down-wide), so very easy wearing and tearing, and this type of copper letter stencil in use lines, letter by thin chap so that smudgy.

Three, summary of the invention:

The utility model technical issues that need to address are to overcome that existing to print the punch height that exists on the technology low, not wear-resisting, the defective that occurs smudgy phenomenon behind the repeated usage, it is existing about 10 times and still keep clearly bearing to print the copper letter stencil through being repeatedly used that a kind of various alphabetical punch height is provided.

The technical scheme that the utility model bearing is printed the copper letter stencil is: the main various alphabetical punch of being made by scale copper (1), copper foundation pile (2), the cylindrical die body (3) that plastics are made, plain conductor (4), insulating resin (5) constitutes, the height that it is characterized in that the various alphabetical punch (1) made by scale copper is 3-4mm, its punch (1) be shaped as the three-dimensional letter shapes of back projection, its all upper surfaces all are in same horizontal surface, and it is parallel and a little less than die body (3), the vertical back of inlaying with foundation pile (2), lower end is welded fixing, foundation pile (2) bottom is fixed on again on die body (3) the annular groove baseplane, and it is interconnected by lead (4), lead (4) one ends pass the outer wall of die body (3) and draw, the other end links to each other with foundation pile (2), die body (3) center is shaped on a through hole, there are three apertures on the through hole limit, the gap of die body (3) annular groove is sealed by insulating resin (5), central through hole is the passage of battery acid when printing bearing, and three apertures of its periphery are used for the location.This kind bearing is printed multiple copper letter stencil because wherein traditional being brought up to about 10 times through the punch height that corrosion is made again by photosensitive of punch aspect ratio, therefore durable in use, not easy to wear, and the letter of printing through being repeatedly used, literal still maintain the original state, clear.

Four, description of drawings:

Fig. 1 prints the front front view of copper letter stencil for the utility model bearing.

Among the figure: 1, punch, 2, foundation pile, 3, die body, 4, lead, 5, insulating resin.

Five, the specific embodiment:

With the engineering plastics center of making through hole is arranged, bore periphery has three knock holees, there is die body (3) (but the pressure injection or use the bar car of annular groove at the edge, mill and shape), be made into various letters with the thick scale copper of 0.08-0.20mm, the copper foundation pile (2) more bigger that height has three-dimensional alphabetical punch of 4mm back projection (1) and quantity to equate approximately than die cross section, then punch (1) one by one with vertical the inlaying of foundation pile (2) after, welding, using lead (4) they to be coupled together embowment at foundation pile (2) position again joins in the annular groove that snaps in die body (3) with moving, and make all upper end surfaces of punch (1) in same horizontal surface, one end of lead (4) passes the outer wall of die body (3) and draws, and uses all spaces of insulating resin (5) packing ring connected in star to make it to solidify at last.For pulse current is effectively discharged, the bearing after the completion is printed the punch upper surface of copper letter stencil and need once be rebuild, and makes word segment a little less than the plane on the die body (3), and its gap is used for pulse current discharging.When bearing face need be printed, the upper surface of printing the copper letter stencil is made it identical, three holes penetrate the bearing pin location, and the centre hole of battery acid from die body injected, and the exit of lead links to each other with the pulse power, and after the several seconds, the letter of promptly finishing on the bearing is printed.

Claims

1, a kind of on bearing face letter punch, the bearing of literal is printed the copper letter stencil, mainly make various alphabetical punch (1) by scale copper, copper foundation pile (2), the cylindrical die body (3) that plastics are made, plain conductor (4), insulating resin (5) constitutes, its feature is 3-4mm by the height of the various alphabetical punch (1) that scale copper is made, its punch (1) be shaped as the three-dimensional letter shapes of back projection, its upper surface all is in same horizontal surface, and it is parallel and a little less than die body (3), lower end and vertical the inlaying of foundation pile (2), foundation pile (2) bottom is fixed on again on die body (3) the annular groove baseplane, and it is interconnected by lead (4), lead (4) one ends pass the outer wall of die body (3) and draw, the other end links to each other with foundation pile (2), then there is a through hole at die body (3) center, bore periphery has three apertures, and the gap of annular groove is sealed by insulating resin (5).
