Description

The straight flanging die of a kind of adjustable L-type part
Technical field
The utility model relates to a kind of mould, particularly the straight flanging die of a kind of adjustable L-type part, and it for adjusting clearance between punch and die, straight flange height and concave-convex mold fillet in straight flanging test.
Background technology
Our unit needs to carry out the straight flanging test of L-type part under different clearance between punch and die, concave-convex mold fillet, plate length and straight flange height.At present, in existing mould, need the how secondary mould of configuration to carry out the straight flanging test of different die size and accessory size, the quantity of mould is multiplied, and this way experimentation cost is high, and the production cycle is long, and inefficiency.
Summary of the invention
The utility model, for the deficiencies in the prior art, proposes the straight flanging die of a kind of adjustable L-type part.
The straight flanging die of a kind of adjustable L-type part of the utility model, comprises die shoe, holding pad, counterdie fixed head, die, adjusting pole, punch elbow-board, punch, convex mould pad, adjustment screw, the first soket head cap screw, the second soket head cap screw, holding screw, upper bolster, push rod, guide pillars and bushes;
Described die shoe is a rectangular structure, upper surface center has a rectangular recess, four manholes are had in groove, a push rod is provided with in each manhole, holding pad is provided with in groove, the top of push rod and the bottom surface of holding pad affixed, the upper bottom surface of holding pad has multiple pin-and-hole; Counterdie fixed head is provided with above the side of die shoe upper bottom surface, counterdie fixed head is provided with die on the upper surface of holding pad side, die, to be fixed by the first soket head cap screw between counterdie fixed head and die shoe, the upper surface of counterdie fixed head away from holding pad side is fixedly installed adjusting pole, be provided with an adjustment screw in adjusting pole in the horizontal direction, adjusting pole is fixed by holding screw; The side top structure of die shoe upper bottom surface and the opposite side top structure of die shoe upper bottom surface except guide pillars and bushes centered by symmetrical;
Punch elbow-board is provided with above holding pad, punch elbow-board bottom surface has a cuboid groove near the two ends of die, a punch is set in groove respectively, two punch are fixedly connected with punch elbow-board respectively by the second soket head cap screw, the top of punch elbow-board is provided with upper bolster, be provided with convex mould pad between punch elbow-board and upper bolster, between die shoe and upper bolster diagonally on be respectively arranged with guide pillars and bushes.
The beneficial effects of the utility model are, can by replacing the fillet of die and punch adjustment die and punch, by rotating adjustment screw adjustment clearance between punch and die, adjusting the relative position of plate and die by the position of the locating hole on plate thus changing straight flange height.The utility model mould structure is simple, simply easy to operate, reduces cost of manufacture, makes the work originally needing how secondary mould to complete become needs and can complete once secondary mould and some dies and punch.
Accompanying drawing explanation

Fig. 2 is the structural representation of the front part of the lower die of work.
Detailed description of the invention
As shown in Figure 1, the straight flanging die of a kind of adjustable L-type part, comprises die shoe 1, holding pad 2, counterdie fixed head 4, die 6, adjusting pole 7, punch elbow-board 8, punch 9, convex mould pad 10, adjustment screw 12, first soket head cap screw 13, second soket head cap screw 15, holding screw 16, upper bolster 17, push rod 18, guide pillar 19 and guide pin bushing 20;
Described die shoe 1 is a rectangular structure, upper surface center has a rectangular recess, four manholes are had in groove, a push rod 18 is provided with in each manhole, holding pad 2 is provided with in groove, the top of push rod 18 and the bottom surface of holding pad 2 affixed, the upper bottom surface of holding pad has multiple pin-and-hole; Counterdie fixed head 4 is provided with above the side of die shoe upper bottom surface, counterdie fixed head 4 is provided with die 6 on the upper surface of holding pad side, die 6, to be fixed by the first soket head cap screw 13 between counterdie fixed head 4 and die shoe 1, the upper surface of counterdie fixed head 4 away from holding pad side is fixedly installed adjusting pole 7, be provided with an adjustment screw 12 in adjusting pole in the horizontal direction, adjusting pole is fixed by holding screw 16; The side top structure of die shoe upper bottom surface and the opposite side top structure of die shoe upper bottom surface except guide pillar 19 and guide pin bushing 20 centered by symmetrical;
Punch elbow-board 8 is provided with above holding pad 2, punch elbow-board 8 bottom surface has a cuboid groove near the two ends of die, a punch 9 is set in groove respectively, two punch 9 are fixedly connected with punch elbow-board respectively by the second soket head cap screw 15, the top of punch elbow-board 8 is provided with upper bolster 17, be provided with convex mould pad 10 between punch elbow-board and upper bolster 17, between die shoe 1 and upper bolster 17 diagonally on be respectively arranged with guide pillar 19 and guide pin bushing 20.
In fig. 2, before work, by push rod 18, holding pad 2 is pushed up the operating position parallel with die 6, the plate having through hole is placed on holding pad 2, and pass through the position of the pin-and-hole on alignment pin 3 and pressing plate material, determine the relative position of plate and die 6, obtain different flange heights; First soket head cap screw 13 and holding screw 16 are loosened, moves die by multiple adjustment screw 12, obtain different clearance between punch and die, fix die by the first soket head cap screw 13 and holding screw 16 afterwards; In Fig. 1 ~ 2, when not die change frame, replaced die 6 and the punch 4 of different concave-convex mold fillet size by the second soket head cap screw 15 and the first soket head cap screw 13, just can obtain the straight flanging die of different concave-convex mold fillet size.During work, forcing press vertical downward movement, the part of the upper die vertical downward movement of driven mold, makes sheet forming, as shown in Figure 1.So just can a more secondary mould bases when under different clearance between punch and die, concave-convex mold fillet, plate length and straight flange height, carry out the straight flanging test of L-type part.
