Description
Technical field
The utility model relates to the industrial processes technical field, hexagonal processing mold in particularly a kind of fluting bolt.
Background technology
At present, along with the extensive utilization of fluting bolt, the fabrication and processing technology of its various piece becomes more and more important.Especially the processing of interior hexagonal is the important procedure during the fluting bolt is produced, and its quality is bigger to following process and performance of products, use influence.But interior hexagonal processing is again the bottleneck operation that the fluting bolt is produced always.Particularly, need adjust axiality through adjustment screw during use because the lower mold body and the gap between the core rod of existing processing mold are very big.Like this, it is big not only to regulate difficulty, and the adjusting time is long, and usually makes because of the vibration during punch press work and be threaded looseningly, and work is extremely unstable.Cause the coaxiality error of hexagonal in the product bigger thus, product percent of pass is lower, has had a strong impact on the total quality and the performance of product.
Summary of the invention
The technical problem that the utility model will solve is: a kind of interior hexagonal processing mold of fluting bolt that can solve hexagonal coaxiality error technical barrier in the product is provided; This mould also has structure comparatively simply, rationally simultaneously, is easy to make, and handling safety is reliable, and the advantage of constant product quality, high conformity is to overcome the deficiency of prior art.
The utility model is achieved in that it comprises upper die body 1; In upper die body 1, be provided with drift fixed cover 2; Be connected with drift fairlead 3 in drift fixed cover 2 lower ends, below drift fairlead 3, be provided with lower mold body 4, in lower mold body 4, have location inner chamber 5; Be provided with lower die-sleeve 6 in inner chamber 5 the insides, location, place the cushion block 7 of lower die-sleeve 6 downsides, the push rod fairlead 8 that is connected with cushion block 7 bottoms, open the lower mold core 9 of groove in lower die-sleeve 6, being provided with.
In the hexagonal processing mold, be connected with the positioning guiding plate 10 of middle perforate at lower mold body 4 tops in the above-mentioned fluting bolt.
In the hexagonal processing mold, on positioning guiding plate 10, evenly offer screw 11 in the above-mentioned fluting bolt, lower mold body 4 is to be connected with positioning guiding plate 10 through the screw of being located in the screw 11.
In the hexagonal processing mold, be provided with locking swivel nut 12 in drift fixed cover 2 and drift fairlead 3 junctions in the aforesaid fluting bolt.
In the hexagonal processing mold, be provided with adjustment screw 13 in the aforesaid fluting bolt in upper die body 1 and drift fixed cover 2 junctions.
In the hexagonal processing mold, in drift fixed cover 2, be provided with and regulate cushion block 14 in the aforesaid fluting bolt.
Owing to having adopted technique scheme, compare with prior art, the utility model adopts unenclosed construction, and is simple and reasonable for structure, and the accuracy of manufacture is easy to guarantee, and is easy to install, debugs and keeps in repair.In addition, inner chamber is installed lower die-sleeve in the location of lower mold body, and lower mold core is installed in lower die-sleeve, has eliminated the gap between lower mold body and the lower mold core, has avoided adding the lower mold core displacement that man-hour, vibration caused effectively; Under the acting in conjunction of drift fixed cover and drift fairlead, guaranteed the location of punch components.Like this; The axiality of product all relies on when making the utility model and guarantees; Need not adjustment during use, improved production efficiency, solved the technical barrier that produces coaxiality error in the fluting bolt in the hexagonal processing; Working stability, Reliable Products steady quality, high conformity are suitable for batch machining production.On this basis, the utility model is installed guide plate at the lower mold body top, makes that the location is more accurate, and the machining accuracy of product is able to further raising.

The specific embodiment:
The embodiment of the utility model: the structure of the utility model is as shown in Figure 1; It comprises upper die body 1 (contour structures of upper die body 1 can be made according to the decompressor connection requirement that reality is used); Drift fixed cover 2 is installed in upper die body 1, is connected and installed drift fairlead 3, lower mold body 4 (contour structures of lower mold body 4 can be made according to the lathe base demand that reality is used) is installed below drift fairlead 3 in drift fixed cover 2 lower ends; In lower mold body 4, offer location inner chamber 5; In inner chamber 5 the insides, location lower die-sleeve 6, cushion block 7, push rod fairlead 8 are installed, cushion block 7 is installed in the downside of lower die-sleeve 6, push rod fairlead 8 is connected with the bottom of cushion block 7 (structure of locating inner chamber 5 is as shown in Figure 2; It is to make according to the dimensional structure of lower die-sleeve 6, cushion block 7, push rod fairlead 8; Promptly satisfying the demand that lower die-sleeve 6, cushion block 7, push rod fairlead 8 take up room gets final product), offer groove in lower mold core 9 inside, make the fluting bolt to be placed in one; And drift 15 can pass through with push rod 16, and lower mold core 9 is installed in the lower die-sleeve 6.For the further accurate fixedly stamping position of drift 15; Improve the machining accuracy of product; The positioning guiding plate 10 of perforate (structure of positioning guiding plate 10 such as Fig. 3 and shown in Figure 4, the size in the hole of offering in the middle of the positioning guiding plate 10 satisfies and can drift fairlead 3 bottoms fixedly be placed in one) in the middle of can installing one at lower mold body 4 tops.In order better positioning guiding plate 10 to be fixed on the lower mold body 4, can on positioning guiding plate 10, evenly offer screw 11, lower mold body 4 is connected with positioning guiding plate 10 through the screw that is installed in the screw 11.For drift fixed cover 2 and 3 more firm being connected of drift fairlead, can locking swivel nut 12 be installed in drift fixed cover 2 and drift fairlead 3 junctions, locking swivel nut 12 can be made into snap-in structure as shown in Figure 1.In order to locate better and to fix, can be at upper die body 1 and drift fixed cover 2 junction install adjustment screws 13, adjustment screw 13 is packed into from the side of upper die body 1, contacts the outer wall of drift fixed cover 2 up to a termination of its embedding.Because the stamping press that receives is excessive and impaired, an adjusting cushion block 14 can be installed drift fixed cover 2 in when preventing drift 15 work.
The utility model in use; Earlier upper die body 1 is installed on the existing decompressor, drift 15 is penetrated in drift fixed cover 2 and the drift fairlead 3 in order to the location, push rod 16 is packed in push rod fairlead 8 and the lower mold core 9; Again push rod 17 is connected the bottom of push rod 16; The bolt of will slotting then places in the lower mold core 9, drift fairlead 3 bottoms is fixedly placed in the mesopore of positioning guiding plate 10 again, and starting decompressor can process.
