Description

A kind of mould of processing groove

Technical field

The utility model relates to a kind of mould of processing groove on plate.

Background technology

Heat radiation product adds man-hour, sometimes need on flitch, process groove, and existing processing technology generally adopts CNC groove milling, and the precision of CNC groove milling technique is high, stay in grade, but production capacity is low, only has 20PCS/ hour, and production cost is up to 2.50 yuan/PCS.

On heat radiation product, process also useful Sheet Metal Forming Technology of depression, when Sheet Metal Forming Technology is normally produced, production capacity is high, production cost is low, but does not generally use in the industry Sheet Metal Forming Technology processing groove, because processing groove is different from the common pitting of processing, the groove of conventional diel processing can produce the material that rises, distortion, quality is unstable, and the drift life-span is short, easy fracture, maintenance cost is high, and gash depth is limited in material thick 1/3.

Utility model content

In view of this, technical problem to be solved in the utility model is to provide a kind of new mould that processes groove on flitch, and this die life is long, the groove stay in grade processing, and groove depth can reach 2/3 of flitch thickness.

Technical problem to be solved in the utility model is achieved by the following technical programs:

A kind of mould of processing groove, comprise patrix and relative to patrix position placing the counterdie of flitch to be processed, described counterdie is provided with flash hole in the corresponding position of the groove to be gone out with flitch, described patrix is fixed with drift, the shape of the ram bottom edge of a knife is designed to the shape of groove to be gone out on flitch, drift sidewall is provided with ribs, and the bottom of the ribs of drift and edge of a knife sidewall are provided with an arc transiting surface.

The utlity model has following beneficial effect:

1, the utility model is equipped with ribs on drift, significantly improved the intensity of drift, and the bottom of ribs and the edge of a knife sidewall design arc transiting surface, can make the stress of edge of a knife punching press flitch better discharge, make not easy fracture of the edge of a knife, can reach 80,000 jig frequencies service life, and maintenance cost is low.

2, drift of the present utility model is gone out after groove in flitch front, and the flitch back side there will be boss, and boss only need cut away with conventional cutting machine, although increased operation, after improving, production capacity is high, can reach 360 PCS/ hour, production cost is low, 0.30 yuan/PCS.

3, the groove that the utility model is gone out is without the material that rises, indeformable, stay in grade, and gash depth can reach 2/3 of flitch thickness.

Accompanying drawing explanation

Fig. 1 is the perspective view that the utility model processes the flitch of groove.

Fig. 2 is the tangent plane shape schematic diagram that processes the flitch of groove.

Fig. 3 is the structural representation of drift.

Fig. 4 is the fit structure schematic diagram of mould described in the utility model and flitch.

The specific embodiment

Below in conjunction with drawings and Examples, the utility model is described in detail.

As shown in Fig. 1 ~ 4, a kind of mould of processing groove, comprise patrix and relative to patrix position placing the counterdie 2 of flitch to be processed 1, described counterdie 2 is provided with flash hole 4 in the corresponding position of the groove 3 to be gone out with flitch 1, described patrix is fixed with drift 5, the shape of the drift 5 bottom edges of a knife 6 is designed to the shape of groove to be gone out on flitch 13, drift 5 sidewalls are provided with has certain thickness ribs 7, and the bottom of the ribs of drift and edge of a knife sidewall are provided with an arc transiting surface 8.

Use the method for this Mould Machining groove to be:

First, this mould is installed on punch press, patrix drives drift 5 to press down, and the edge of a knife 6 stamps out the shape of groove 3 on flitch 1, and the material of going out is pressed in the flash hole 4 of counterdie, makes the flitch back side produce boss 9; Then, with a conventional cutting machine, the boss producing 9 is excised.By after boss 9 excisions, the flitch back side can leave cut channel, and in production process, rear operation has drawing process, can remove cut channel.

The above embodiment has only expressed embodiment of the present utility model; it describes comparatively concrete and detailed; but can not therefore be interpreted as the restriction to the utility model the scope of the claims; as long as employing is equal to the technical scheme that the form of replacement or equivalent transformation obtains, within all should dropping on protection domain of the present utility model.

Claims

1. a mould of processing groove, it is characterized in that: comprise patrix and relative to patrix position placing the counterdie (2) of flitch to be processed (1), described counterdie is provided with flash hole (4) in the corresponding position of the groove to be gone out with flitch (3), described patrix is fixed with drift (5), the shape of the ram bottom edge of a knife (6) is designed to the shape of groove to be gone out on flitch, drift sidewall is provided with ribs (7), and the bottom of the ribs of drift and edge of a knife sidewall are provided with an arc transiting surface (8).
