Abstract
The utility model discloses a mould, the prior art of accomplishing three processes of shaping, turn-ups, punching a hole occupies two presses or the mould is complicated with high costs. The die is provided with a squeezing and cutting head with a stabbing knife at the middle part of a fillet at the edge of the top end, the edge of an inner hole of a female die is provided with a chamfer, and the stabbing knife is cut into a workpiece after the upper die and the lower die are formed. When the convex die is pressed to the concave die, the belleville spring is compressed, and the workpiece material near the top end of the extruding and cutting head is bent downwards along the chamfer angle of the inner hole edge of the concave die to finish flanging. The die has simple structure, easy processing and low cost, and can realize the forming, flanging and hole cutting of a larger workpiece on one single-action press.
Description
The utility model is a kind of cold-working processing mold.
The head of power transformer gilled radiator need the processing through overmolding, flange, punching three process.Prior art is following two kinds: 1, finish moulding, punching (punch shape complexity, difficult processing) earlier, carry out flange again on another forcing press.This two steps operation takies two forcing presses, two work-yards and stacks place, need two cover operators, and the difficulty of processing of flanging die is also bigger.2, realize the compound of three operations with routine techniques on a forcing press, this must adopt complicated mould structure and supplementary means, the die cost height, and the difficulty of adjustment and maintenance is also bigger.
It is low that the purpose of this utility model provides a kind of handling ease cost simple in structure, can realize shaping, the flange of big product and cut the compound mould of hole three operations on a single action press.
Structure of the present utility model is as follows: mould includes cope match-plate pattern 1, lower bolster 7, patrix 3, counterdie 10, punch 4, die 9, squeeze the disk spring 12 between crop 2 and cope match-plate pattern 1 and the patrix 3, it is characterized in that crowded crop 2 vertically downward is fastened on the cope match-plate pattern 1, the middle part that the part or all of edge on crowded crop 2 tops has fillet and top is fastened with stamp cutter 6, and the respective edges that is fastened on the endoporus of the die 9 on the lower bolster 7 has chamfering.
The course of work: workpiece enters mould, and slider of punch is descending, finishes moulding by patrix 3 and counterdie 10.Simultaneously, squeeze the position 8 that the stamp cutter 6 incision workpiece on the crop 2 are wanted perforate, material stabs and opens an openning herein.Descending along with slide block, openning enlarges gradually, and the molded place of workpiece material is lived by upper and lower mold pressing.Increasing because of pressure, so being difficult for producing, material flows.When punch 4 is depressed into die 9, patrix is just no longer descending, but cope match-plate pattern 1 is still driven continuation descending (disk spring 12 continues to be compressed, and the molded part of workpiece is carried out shaping) by slide block, near crowded crop 2 tops workpiece material is with under the chamfering curved along the interior bore edges of die 9, finish flange.Continuation with cope match-plate pattern is descending, squeezes crop head fillet and workpiece and wants perforate position storeroom to produce slip, and will locate material and continue toward pressing down, entering in the die vestibule, the hole portion material behind the flange is squeezed off until crowded crop.Then slide block is up, and punch press is finished one stroke.The one stroke of punch press has been finished shaping, flange like this and has been cut three operations in hole.The waste material of staying in the die hole is extruded the lower bolster material spilling hole by waste material afterwards, so liftout attachment needn't be set.
As seen, the utility model has adopted following special construction:
1, with stabbing the position 8 that cutter 6 incision workpiece are wanted perforate, material stabs and opens an openning herein, cause " the weak district condition " of this place's material, make this place's material when flange, be easy to flow, the unlikely material of moulding section that causes flows, the product distortion is reduced, also reduced the flange stamping press, simplified mould.
2, the crowded crop 2 that adopts tip edge to have fillet replaces the common drift that keen edge is arranged, and produces slip between the material that makes the flange place and crowded crop and is not cut off.Band was finished flange down when the crowded crop of material quilt at flange place was descending.It is descending to squeeze the crop continuation after flange is finished, and squeezes off hole portion waste material.In this measure, finish by " band down " by crowded crop for flange, so punch need not made flange shape (punch flange shape is difficult to processing, is again weak part), simplified mould again.
3, establish disk spring 12 between cope match-plate pattern 1 and the patrix 3, the shut height that makes mould is a scope but not certain value had so both made the installation adjustment of mould easy, has improved the security of operation again.
In sum, the utility model has the advantages that handling ease cost simple in structure is low, labor savings, work-yard and equipment, adjust easy for installation, handling safety.
Fig. 1 looks cross-sectional view for the master of embodiment.
Fig. 2 is the workpiece shape schematic diagram that mould shown in Figure 1 processed, and wherein (A) is front view, (B) is left view, (C) is the A-A profile.
Below further specify the utility model with embodiment, but scope of the present utility model is not limited to process the mould of power transformer gilled radiator head, also can be the mould of other workpiece of processing.
Embodiment: see Fig. 1, for processing the mould of power transformer gilled radiator head shown in Figure 2.Crowded crop 2 vertically downward is fastened on the cope match-plate pattern 1, and the middle part that the head portion edge of crowded crop 2 has fillet and top is fastened with stamp cutter 6, and the endoporus respective edges that is fastened on the die 9 on the lower bolster 7 has chamfering.The upper and lower compact heap 5 on band inclined-plane tightens on patrix 3 and counterdie 10 with screw respectively, makes the dismounting and change of punch 4 and die 9 very convenient.8 is the position of wanting perforate on the workpiece 11 among the figure.12 is the disk spring between cope match-plate pattern 1 and the patrix 3.
Claims (2)
