Description
Technical field
The utility model relates to a kind of forging press, is specifically related to a kind of device for reducing to forge and press error.
Background technology
Modern society, the application of automobile is more and more extensive, rides instead of walk, and tourism etc. function, there is several automobile production big countries in China, to tackle and domestic growing automobile demand.
The manufacturing process of automobile is complicated, and each part necessarily requires work processed meticulous, and error is little, and forging and stamping are exactly wherein one of requisite operation.
Present forging press is less for the design means of error, adopt general device, error is too large, cannot meet index request, and adopt the modes such as laser positioning, cost is too high again, and due to automobile being widely used in real life, the error of internals will have influence on actual use, so for the control forging and pressing error, very necessary.
Utility model content
Utility model object: it is comparatively large that the utility model solves existing forging press error, meanwhile, although adopt the mode precision such as laser positioning high, the problem that cost is also high.
Technical scheme: for achieving the above object, the utility model provides following technical scheme: a kind of for reducing the device forging and pressing error, the die shoe comprising upper bolster and match with it, described upper bolster there is the upper groove for fixing honest thick patrix, honest thick patrix is fixed in upper groove by upper molded plate and the cooperation of upper molded plate bolt, the position that die shoe mates with upper groove position is provided with low groove, and low groove internal fixtion has the honest thick counterdie with honest thick patrix adaptation; Upper molded plate is L-type, and its minor face embeds upper bolster and slides in order to prevent upper molded plate, and the honest thick patrix fastening bolt of underrun that described honest thick patrix embeds upper bolster is fixed on upper bolster; Described upper bolster is provided with guide pillar away from the side of honest thick patrix.
As optimization, described guide pillar two ends embed upper bolster and die shoe respectively, and are slidably arranged between upper bolster and die shoe by guide pin bushing.
As optimization, described guide pillar be shorter in length than upper bolster and die shoe separately after for placing the distance up and down between cavity floor of guide pillar.
As optimization, described upper bolster is provided with the caulking groove preventing upper molded plate from sliding.
As optimization, the external diameter of described guide pillar is less than the internal diameter of guide pin bushing, and error range is at 0 ~ 2mm.
As optimization, described upper bolster is provided with the guide pillar cover plate for preventing guide pillar from marking upper bolster, and guide pillar cover plate is arranged at the upper plenum bottom surface of guide pillar place upper bolster.
As optimization, the length of described guide pin bushing is greater than upper bolster for placing the degree of depth of the upper plenum of guide pillar, is less than the length of guide pillar.
As optimization, described upper molded plate one end is fixed in the caulking groove of upper bolster, and the other end is fixedly connected with honest thick patrix.
Operation principle: upper bolster and die shoe pass through the location of guide pin bushing inner guiding post, along the upper and lower pressing in guide pillar direction, and in bonding processes, due to the existence of upper molded plate, honest thick patrix and honest slightly counterdie can not exist cheaply, the accuracy of impact forging and stamping.
Beneficial effect: the utility model compared with prior art: employing upper molded plate is L-type; and there is upper bolster to be provided with the design of the caulking groove preventing upper molded plate from sliding; in order to prevent after forging and stamping repeatedly; cheap situation can be there is in honest thick patrix; improve the accuracy of forging and stamping; simultaneously; the length of described guide pin bushing is adopted to be greater than upper bolster for placing the degree of depth of the upper plenum of guide pillar; the external diameter of the length and guide pillar that are less than guide pillar is less than the internal diameter of guide pin bushing; and error range is at 0 ~ 2mm, prevents guide pillar from marking planned orbit and cause the excessive problem of error that forges and presses.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is cross section structure schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, these embodiments should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
As depicted in figs. 1 and 2, a kind of for reducing the device forging and pressing error, the die shoe 2 comprising upper bolster 1 and match with it, described upper bolster 1 there is the upper groove 4 for fixing honest thick patrix 3, upper molded plate 5 and upper molded plate bolt 6 coordinate and are fixed in upper groove 4 by honest thick patrix 3, the position that die shoe 2 mates with upper groove 4 position is provided with low groove 7, and low groove 7 internal fixtion has the honest thick counterdie 8 with honest thick patrix 3 adaptation; Upper molded plate 5 is L-type, and its minor face embeds upper bolster 1 and slides in order to prevent upper molded plate 5, and the honest thick patrix fastening bolt 9 of underrun that described honest thick patrix 3 embeds upper bolster 1 is fixed on upper bolster 1; Described upper bolster 1 is provided with guide pillar 10 away from the side of honest thick patrix 3.
