Detailed description of the invention
Below in conjunction with the drawings and the specific embodiments, the utility model is described in detail.
See figures.1.and.2, it is the structure of six side's blind hole workpiece 1 in the utility model large scale to be processed, interior six side's blind holes 2 are designed with in the big end surface center of workpiece 1, the little head end outside diameter of workpiece 1 is D, interior six side's blind hole 2 circumscribed circle diameters are E, the opposite planar distance of interior six side's blind holes 2 is S, and the blind hole depth of interior six side's blind holes 2 is H.
Processing tool of the present utility model, comprises interior six side's punching pines 3, horizontally disposed opening backing plate 6 and opening pressing plate 8, two equal height cushion blocks 1 vertically arranged and two equal height cushion blocks 2 12,
With reference to Fig. 3 and Fig. 4, the structure of interior six side's punching pines 3 is, comprise the drift 4 and drift chassis 5 thereof that are wholely set, six square chi cun (comprising diagonal F, opposite planar distance B and height of punch h) of drift 4 are corresponding consistent respectively with default six square chi cun (circumscribed circle diameter E, opposite planar distance S and blind hole depth H) of six side's blind holes 2 interior on workpiece 1 respectively; The width dimensions on drift chassis 5 should be identical with the size B on the opposing parallel limit of drift 4, and the length dimension on drift chassis 5 is much larger than the Diagonal Dimension F of drift 4; Interior six side's punching pines 3 adopt grinding tool steel making, need through Quenching Treatment to gain in strength.
With reference to Fig. 5 and Fig. 6, the structure of opening backing plate 6 is, from opening backing plate 6 center towards the opening 7 being provided with UNICOM, the opening size of opening 7 is greater than microcephaly's outside diameter D of workpiece 1 and is less than the major part outside diameter E of workpiece 1, for supporting clamping workpiece 1.
With reference to Fig. 7 and Fig. 8, the structure of opening pressing plate 8 is, the groove width K of opening pressing plate 8 is at least greater than the 2-3mm on drift chassis 5 width (size B), and the fluting of opening pressing plate 8 is highly at least greater than the 2-3mm of interior six side's punching pin 3 height overall P.
Processing tool of the present utility model, in the process for six side's blind holes in large scale, according to the supporting enforcement of following steps:
Step 1, brill bottom outlet, heating
First get out bottom outlet in workpiece 1 big end surface center according to the size of interior six side's blind holes 2, bottom diameter and interior six side's blind hole 2 opposite planar distance S-phase to be processed are together, again workpiece 1 is heated in heating furnace, to facilitate six side's blind holes 2 in punching, notice that heating-up temperature can not exceed the temperature of workpiece 1 material, in order to avoid affect the material property of workpiece 1;
Step 2, punching
With reference to Fig. 9, press bench 9 places two equal height cushion blocks 1, level overlap joint opening backing plate 6 between these two equal height cushion blocks 1, the workpiece 1 heated vertically is put in the opening 7 of the opening backing plate 6 of horizontal positioned, the little head end of workpiece 1 lower end is between these two equal height cushion blocks 1, and the stub end of workpiece 1 upper end rides over edge on opening 7; Six side's punching pines 3 in the bottom outlet of workpiece 1 is placed, make drift 4 align with the bottom outlet of workpiece 1; Then, operating pressure machine makes head 11 upper surface, punching press drift chassis 5 downwards, drift 4 pours in the bottom outlet of workpiece 1 under the suppressing action of head 11, contact until the lower surface on drift chassis 5 is adjacent to the upper surface of workpiece 1, complete punching, now, workpiece 1 and interior six side's punching pines 3 will be crimped and connect together, one state as shown in Figure 10.
Opening backing plate 6 is for increasing stability during workpiece 1 clamping, and two pieces equal height cushion block 1 is for supporting opening backing plate 6, and the height of two pieces equal height cushion block 1 should make the lower end of workpiece 1 not contact with press bench 9; Interior six side's punching pines 3 are placed in workpiece 1 upper surface, and drift 4 should align with the bottom outlet of workpiece 1, can adopt the aid clamping drift chassis 5 such as clamp so that fixing interior six side's punching pines 3.
Step 3, separation workpiece 1 and interior six side's punching pines 3
With reference to Figure 11, Figure 12, press bench 9 is settled two equal height cushion blocks 2 12 again, the workpiece 1 connect one and interior six side's punching pines 3 are vertically placed between two equal height cushion blocks 2 12, be overlapped on edge on two equal height cushion blocks 2 12 by drift chassis 5 (along its length), workpiece 1 is between two equal height cushion blocks 2 12; Again opening pressing plate 8 is placed on workpiece 1 upper surface, and the fluting of opening pressing plate 8 rides on drift chassis 5 downwards; Last operation forcing press makes head 11 punched openings pressing plate 8 downwards, and the active force of undershoot passes in the big end surface of workpiece 1 by opening pressing plate 8, and workpiece 1 is moved down, and drift 4 is deviate from from interior six side's blind holes 2, and workpiece 1 and interior six side's punching pines 3 are thrown off.
Utilize two pieces equal height cushion block 2 12 to hold drift chassis 5, workpiece 1 and interior six side's punching pin 3 integral support are got up, the height of two pieces equal height cushion block 2 12 is at least greater than the height h of drift 4 and the height overall sum of workpiece 1, and such drift 4 could be rushed out from workpiece 1.
Processing tool of the present utility model, structure is simple, swift to operate, hand labor intensity is low, improves the efficiency of six side's blind holes in processing small batch large scale.
