Fig. 4 is the preparation flow schematic diagram of the sheet metal nut pressing product involved by this utility model embodiment; The change schematic diagram of the sheet metal nut pressing product of Fig. 5 involved by the utility model in preparation process.
As shown in Figure 4 and Figure 5, the preparation flow of sheet metal nut pressing product comprises the following steps:
Step 1 (S-1), the coiled material that epigyny device transports by coiled material cutter sweep cuts into the blank 10 of certain size;
Step 2 (S-2), the second driving mechanism in conveying device 2 drives blank 10 to move along the groove in supporting mechanism 21 with first drift 311 of the mode of decrease of speed to die mechanism 31, when the center of blank 10 and the first drift 311 contact, the translational speed of blank 10 is zero;
Step 3 (S-3), first driving mechanism drives die mechanism 31 and die mechanism 32 simultaneously near blank 10, first time punching press drawing is carried out to blank, form the first drawing product 20, away from the first drawing product 20 while that die mechanism 31 and die mechanism 32 being under the driving of the first driving mechanism afterwards;
Step 4 (S-4), first drawing product 20 moves with second drift 312 of the mode of decrease of speed along groove to die mechanism 31 equally under the promotion of blank 10, when the center of the first drawing product 20 and the second drift 312 contact, the translational speed of the first drawing product 20 is zero;
Step 5 (S-5), first driving mechanism drives die mechanism 31 and die mechanism 32 simultaneously near blank 10 again, while the first drift 311 carries out first time punching press drawing to new blank 10, second drift 312 carries out second time punching press drawing to the first drawing product 20, form the second drawing product 30, away from the second drawing product 30 while that die mechanism 31 and die mechanism 32 being under the driving of the first driving mechanism afterwards;
Step 6 (S-6), the second drawing product 30 continues to move forward under the promotion of new the first drawing product 20 formed, and is carried out third time, the 4th time, the 5th time punching press drawing successively, forms the 5th final drawing product 60;
Step 7 (S-7), jumping-up apparatus for leveling carries out jumping-up and leveling to the 5th drawing product 60, forms jumping-up product 70;
Step 8 (S-8), hole punched device carries out punching to jumping-up product 70, forms pressing product 80.
As shown in Figure 5, blank 10 is in square, and in follow-up continuous drawing process, because blank is subject to the punching press of drift, the length of side of all drawing products no longer linearly, but is slight arc shape.
From the first drawing product 20 to final drawing product, that is, the 5th drawing product 60, deep-drawn parts gradually elongated, attenuate.Because the 5th drift is pierce punch, therefore, while the deep-drawn parts of the 5th drawing product 60 is extended, also got through bottom it.The thick product 70 of upsetting is compared to the 5th drawing product 60, and the wall of deep-drawn parts is long to be reduced, and the diameter of bottom through hole also reduces due to the thick effect of upsetting simultaneously, needs again to carry out punching, forms final pressing product 80.
In the present embodiment, the drift number in die mechanism is set to 5, and blank, through five road continuous drawings, forms drawing product.In fact the number of drift is not limited to 5, can set the number of drift according to actual needs.
The effect of embodiment and effect
The continuous drawing device provided according to the present embodiment and sheet metal nut pressing product manufacturing equipment, successively decrease because die mechanism is disposed with a plurality of external diameter along transport path, the drift of increasing lengths, in die mechanism, the position corresponding with a plurality of drift is respectively arranged with internal diameter and is highly all greater than the groove of drift external diameter simultaneously, for holding the deep-drawn parts of sheet metal nut and carrying out moulding to it, drifts all when die mechanism is moved downward can carry out extruding drawing to the sheet metal nut blank of the different conditions on transport path simultaneously, sheet metal nut blank is in the process along transport path onwards transmission, extruded by the drift of different size gradually, form drawing product, solve in prior art and need multiple stage cold extrusion device to work simultaneously, cause the problem that part processing cost is high.
Simultaneously, because multiple drift is arranged on same mechanism, carry out the operation of extruding drawing simultaneously, make the machining deviation of each step in whole drawing process can be controlled in identical scope, the wall thickness being conducive to improving sheet metal nut deep-drawn parts all with spend, and then the precision of raising screw thread.
In the above-described embodiments, the groove on the drift of die mechanism and die mechanism is one to one.As continuous drawing device of the present utility model and sheet metal nut pressing product manufacturing equipment, the moulding effect of groove can also be made full use of, namely, the number of groove is greater than the number of drift, as drift is set to 3, and groove is set to 5, the form of still successively decreasing in increasing lengths, internal diameter.In the latter two steps of continuous drawing process, the drawing product that last procedure only need be formed by die mechanism is depressed in corresponding groove.
The utility model is not limited to the scope of detailed description of the invention; to those skilled in the art; as long as various change to limit and in the spirit and scope of the present utility model determined in described claim; these changes are apparent, and all innovation and creation utilizing the utility model to conceive are all at the row of protection.
