Side wall shrinkage pool in, there is upper mould to install groove at the bottom surface of connecting plate middle part, and upper mould sleeve is in upper mould installs groove and fixes
The top surface of groove is installed in upper mould, upper mould is in the surface of lower mould.
The both sides of the lower mould contiguous block have the extension for stretching out, and the top surface of extension is fixed with limited post, even
Connection block is fixed with two lateral walls of fishplate bar, limited post sleeve is bolted with positioning in connection block, at the top of limited post
Nut, is inserted with buffer spring in limited post, extension is put forth effort in the lower end of buffer spring, and company is put forth effort in the upper end of buffer spring
Connect block.
There is steel plate to place groove at the top surface middle part of the lower mould, and the bottom surface that steel plate places groove has multiple punching press shrinkage pools
With multiple mounting grooves, it is nested in mounting groove and be fixed with permanent magnet blocks.
The top surface that the top surface that the upper mould installs groove has multiple location holes, upper mould has multiple spacing preiection posts, limit
In location hole, the top surface of upper mould also forms multiple and is spirally connected bar position convex column sleeve, and the top of the bar that is spirally connected is through the installation of upper mould
Connection through hole that the top surface of groove has simultaneously is bolted with two nuts being mutually pressed against, and the bottom surface of upper mould has and punching press shrinkage pool phase
Corresponding stamped bumps.
The middle top surface of the connecting plate is fixed with connector.
The beneficial effects of the present invention are:
Its simple structure, small volume, lower mould easy installation and removal, steel plate installs accurate positioning, convenient, greatly improves making
Effect.
Brief description of the drawings:
Fig. 1 is structural representation of the invention.
Specific embodiment:
Embodiment:As shown in Figure 1, a kind of steel plate punched mold for forming device, including lower mould contiguous block 10 and connecting plate
20, the bottom surface that the top surface middle part of the lower mould contiguous block 10 has lower mould fixed groove 11, lower mould fixed groove 11 has multiple
Positioning jack 12, is inserted with strong magnet set 13 in positioning jack 12, the lateral wall of strong magnet set 13 is fixed on positioning jack 12
On madial wall, in lower mould fixed groove 11, the bottom surface of lower mould 14 has multiple inserted links 141, the sleeve of inserted link 141 to the lower sleeve of mould 14
Strong magnet set 13 in and adsorb strong magnet cover 13 in, spiral shell in the through hole that is spirally connected having on the madial wall of lower mould fixed groove 11
It is connected to multiple positioning studs 15, in the end sleeve of positioning stud 15 has on the lateral wall of lower mould 14 side wall shrinkage pool 142,
There is upper mould to install groove 21 at the bottom surface middle part of connecting plate 20, and the sleeve of upper mould 22 is in upper mould installs groove 21 and is fixed on mould
The top surface of groove 21 is installed, upper mould 22 is in the surface of lower mould 14.
Further, the both sides of the lower mould contiguous block 10 have the extension 16 for stretching out, the top of extension 16
Face is fixed with limited post 17, and connection block 23 is fixed with two lateral walls of connecting plate 20, and the sleeve of limited post 17 is in connection block
In 23, the top of limited post 17 is bolted with location nut 18, buffer spring 19 is inserted with limited post 17, under buffer spring 19
Extension 16 is put forth effort at end, and connection block 23 is put forth effort in the upper end of buffer spring 19.
Further, there is steel plate to place groove 143 at the top surface middle part of the lower mould 14, and steel plate places groove 143
Bottom surface has multiple punching press shrinkage pools 144 and a multiple mounting grooves, nested in mounting groove and be fixed with permanent magnet blocks 145.
Further, the upper mould installs the top surface of groove 21 with multiple location holes 211, and the top surface of upper mould 22 has
Multiple spacing preiection posts 221, in location hole 211, the top surface of upper mould 22 also forms multiple and is spirally connected the sleeve of spacing preiection post 221
Bar 222, connection through hole 212 that the top surface that groove 21 is installed in the top of the bar 222 that is spirally connected through upper mould has simultaneously is bolted with two phases
The nut 223 being mutually pressed against, the bottom surface of upper mould 22 has the stamped bumps 224 corresponding with punching press shrinkage pool 144.
Further, the middle top surface of the connecting plate 20 is fixed with connector 24.
Operation principle:Sheet metal (typically in 0.1mm to 0.3mm thickness) is placed in steel plate placement groove 143, is passed through
Permanent magnet blocks 145 carry out absorption stationary positioned, when upper mould 22 is moved down, the speed that upper mould 22 is pushed can be ensured by buffer spring 19
Degree, prevents decline too fast, is pushed by upper mould 22 so that stamped bumps 22 are pressed against on sheet metal and cause the correspondence of sheet metal
Bottom insertion punching press shrinkage pool 144 in, complete punch forming.
Wherein, in the present embodiment, its lower installing/dismounting of mould 14 can be realized fixing by rotational positioning stud 15, and pass through
Strong magnet set 13 carries out further absorption and fixes.
