Abstract
The utility model discloses a mosaic sleeve device for a stamping pilot hole. The mosaic sleeve device for the stamping pilot hole comprises a stripper plate and a stripper fixing plate; positioning dowels and a fastening bolt which is used for connecting the stripper plate and the stripper fixing plate are arranged between the stripper plate and the stripper fixing plate; a hollow hole is formed on the stripper fixing plate; and a pilot hole corresponding to the hollow hole is formed on the stripper plate and a hard alloy sleeve for the pilot hole is inlaid therein. The mosaic sleeve device overcomes the shortcoming that the abrasion of a via hole on the stripper plate leads the pilot hole to fail in piloting, and further changes the form of the via hole of a pilot nail in the traditional stripper plate and additionally arranges the hard alloy mosaic sleeve device for the stamping pilot hole on the stripper plate, so as to solve the problem that the via hole has much possibility of abrasion; meanwhile, the low probability of abrasion of hard alloy can greatly prolong the service life of the stripper plate and lessen heavy repair to dies due to the abrasion of the via hole of the stripper plate.
Description
Technical field
The utility model relates to a kind of diel, is specifically related to punching press correcting hole mosaic set device in a kind of cold stamping industry.
Background technology
At present, at home in the silicon steel sheet stamping-out industry, be to adopt the circle correcting to follow closely the material of correcting institute punching press, in order to guarantee the product size precision for considerable progressive die.But, correcting nail via hole on present most of mould stripper is cut out by slow silk, perhaps grind by coordinate, in the process of punching press, its mutual friction mutually with the correcting nail causes via hole to become big extremely easily, causes the correcting nail to rock in stripper, lose the effect of correcting stamping material, cause product size to be difficult to guarantee, can't ordinary production, the problems referred to above are perplexing silicon steel punching manufacturing enterprise for a long time always.
The utility model content
The utility model technical issues that need to address just are, overcome in the prior art that correcting nail via hole weares and teares easily on the stripper, the correcting nail loses the effect of correcting stamping material, can not effectively guarantee the defective of product quality, a kind of punching press correcting hole mosaic set device is provided, it can solve because of via hole friction on correcting nail hole and the stripper, and stripper becomes big ineffective problem, the life-span that can greatly improve mould because of via hole.
For achieving the above object, the technical solution adopted in the utility model is a kind of punching press correcting hole mosaic set device, it is characterized in that, this device includes stripper, discharging fixed head, between described stripper and discharging fixed head, be provided with shop bolt, and the fastening bolt that is used to connect described stripper and discharging fixed head, on described discharging fixed head, be provided with hollow hole, position corresponding to described hollow hole on described stripper is provided with the correcting hole, tungsten carbide button's correcting borehole jack in described correcting hole.
For the ease of the use and the installation of correcting borehole jack, the utility model is designed to the multidiameter shape with the outside of described correcting borehole jack, and the step end roof pressure of described multidiameter is at described joint face one end of stating stripper and discharging fixed head.
In order to make inlay between correcting borehole jack and the stripper firm, in the utility model, be interference fit between described tungsten carbide button correcting borehole jack and the described correcting hole.
In the utility model, can be connected with hexagonal fastening bolt in several between described stripper and the discharging fixed head.
Advantage of the present utility model and beneficial effect are: in order to overcome correcting nail via hole wearing and tearing on the stripper, thereby lose the difficult problem of guide effect, the utility model changes traditional stripper correcting and followed closely well format, on stripper, add carbide alloy correcting nail hole mosaic set device, solved the easy wear problems of via hole, simultaneously, because carbide alloy is not easy to wear, prolong the life-span of stripper greatly, reduced the mould overhaul of carrying out because of the wearing and tearing of stripper via hole.
The utility model cuts the correcting hole in advance on stripper, the mode that carbide alloy correcting borehole jack adopts interference to inlay is knocked in, and the anti-stripper reverse side that hangs over of the step part of mosaic set is used for locating up and down.With the pin location, connect between stripper and the discharging fixed head with bolted.Being inlaid with the corresponding discharging fixed head of correcting borehole jack part hollow out, so that the mounting or dismounting of mosaic set with stripper.
In the utility model, the mosaic set material adopts carbide alloy, and it is processed by internal and external grinding machine, and the fineness of hole wall also can be guaranteed, and the wearing and tearing that these have greatly delayed the correcting borehole jack have guaranteed the accurate guide effect of correcting borehole jack.
In the utility model, taked the above mode though inlay the correcting borehole jack, the wearing and tearing in hole have been delayed greatly, long-time such hole later on also is to have wearing and tearing after all, so in the utility model but in fact,, hollow out on the discharging fixed head of mosaic set correspondence, so that after the wearing and tearing of carbide mosaic cover, directly pound out the carbide mosaic cover under the situation of not changing, do not install and remove stripper, dress is with new mosaic set.
In the utility model, simple in structure clear, not only solved stripper correcting nail hole wear problems, also avoid simultaneously having significantly reduced in other words mould overhauls such as the replacing stripper action that causes because of the hole wearing and tearing of stripper correcting nail, greatly improve the precision and the service efficiency of mould, improved production efficiency.For energy-saving and cost-reducing, improve production capacity and all have bigger meaning.
Description of drawings
Fig. 1 is the structural representation of the utility model punching press correcting hole mosaic set device.
Among the figure: 1, stripper; 2, correcting borehole jack; 2-1, step; 3, discharging fixed head; 4-1,4-2, shop bolt; 5, fastening bolt; 6, correcting hole; 7, hollow hole.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
Embodiment 1
As shown in Figure 1, a kind of punching press correcting of the utility model hole mosaic set device, this device includes stripper 1, discharging fixed head 3, between described stripper 1 and discharging fixed head 3, be provided with shop bolt 4-1,4-2, and the fastening bolt 5 that is used to connect described stripper 1 and discharging fixed head 3, be provided with hollow hole 7 on described discharging fixed head, the position corresponding to described hollow hole 7 on described stripper 1 is provided with correcting hole 6, tungsten carbide button's correcting borehole jack 2 in described correcting hole 6.
On the basis of embodiment 1, the utility model preferred embodiment is, use and installation for the ease of correcting borehole jack 2, the utility model is designed to the multidiameter shape with the outside of described correcting borehole jack 2, with the step 2-1 of described multidiameter end roof pressure at described joint face one end of stating stripper 1 and discharging fixed head 3.In order to make inlay between correcting borehole jack 2 and the stripper 1 firm, in the utility model, be interference fit between described tungsten carbide button correcting borehole jack 2 and the described correcting hole 6 simultaneously, all the other and embodiment 1 are identical.
