Below against attached drawing, by the description of the embodiment, making further details of theory to the specific embodiment of the invention
It is bright, to help those skilled in the art to have more complete, accurate and deep reason to the inventive concept of the present invention, technical solution
Solution.
Embodiment 1
As Figure 1-Figure 4, the present invention provides a kind of piercing dies of the automatic switchover punch of bogie longitudinal beam reinforcing plate
Tool, including cope plate 2, guide post 8, guide post bushing 9, backing plate 5, fixed plate 6, punch guide plate 7, stripper 4 and concave template 3.Institute
State punching die be mounted on can be along the lathe bed that oil pressure machine base guide rail vertically moves, the bogie longitudinal beam reinforcing plate passes through
Automatic feeding transverse shifting feeding.
Backing plate 5 is mounted on cope plate 2 in the following, fixed plate 6 is mounted on the backing plate 5 in the following, three passes through big positioning pin 12
Positioning, is fixed together with big fastening bolt 11.Punch guide plate 7 is fixedly mounted on the fixed plate 6 in the following, stripper 4
In 7 lower section of punch guide plate.It is fixedly mounted on the cope plate 2 there are two big cylinder 1, big cylinder 1 is symmetrically mounted on described
The middle of 2 both sides of cope plate.The piston rod end of the big cylinder 1 is fixed on above the stripper 4, the stripper 4
It is located at the lower section of the punch guide plate 7.
Several punches 14 and the corresponding several punches for controlling the punch 14 and whether exposing are installed in the fixed plate 6
Control mechanism, the two correspond, and the punch control mechanism includes small cylinder 10 and baffle 15.It is the concave template 3, described
It is designed on stripper 4 and the punch guide plate 7 and 14 one-to-one through-hole of the punch.The top both sides of fixed plate 6
Multiple grooves being distributed symmetrically are set, a small cylinder 10 is fixedly mounted in each groove.The piston rod of small cylinder 10 is horizontal
It stretches out, top is overlapped with plate washer.The baffle 15 coordinates with the groove gap, and the baffle 15 is by the small cylinder 10
It is located at 14 top of the punch after ejection, covers the top surface of punch 14.The punch 14 is from 4 exposed portion of the stripper
Length is not more than the thickness of the baffle 15.
Several punch sets 16, punch set 16 are installed by two small positioning pins and two stove bolts in the fixed plate 6
It is corresponded with the punch 14.The punch covers 16 upper sides and is equipped with the opening being inserted into for the baffle 15, punch set 16
Position and quantity are corresponding with baffle 15, and the punch 14 is slidably mounted in the corresponding punch set 16.It is described
It is installed with several and 14 one-to-one punch of the punch in concave template 3 and covers 17, the punch covers the upper of 17 endoporus
Section coordinates with the punch segment 20, and the hypomere of the endoporus is the larger back taper of lower ending opening, installs the punch set 17
Hydraulic press operating platform 13 is equipped with and the matched material-dropping hole of endoporus lower ending opening.The waste material that punch 14 generates is facilitated to fall
Under.
Concave template 3 fixes downlink connection with hydraulic press operating platform 13, can be vertically moved with hydraulic press operating platform 13.Punching
First 14 with punch set 16, punch guide plate 7, stripper 4 be dynamic cooperation.The punch 14 is divided into top from top to bottom
The section of plate 18, changeover portion 19 and punch segment 20, the changeover portion 19 is less than the upper plate 18, and the changeover portion 19 is cut
Face is the rectangle that apex angle is fillet.The section of the punch segment 20 is less than the changeover portion 19.
The center sliding slot of punch set 16 be divided into the top sliding slot being slidably matched with the upper plate 18 and with the mistake
It crosses section 19 to be slidably matched lower part sliding slot, the through-hole on the punch guide plate 7 is punch pilot hole, is divided into and the changeover portion
The 19 pilot hole epimeres being slidably matched and the pilot hole hypomere being slidably matched with the punch segment 20.Upper plate 18 declines in this way
When blocked by lower part sliding slot top, changeover portion 19 decline when blocked at the top of the pilot hole hypomere, it is not easily to fall off.
The guide post bushing 9,8 lower end of the guide post and the stripper 4 are pressed on four angles of the cope plate 2
Tight fit connection, the guide post bushing 9 are slidably matched with the guide post 8.The two plays guiding role.
Above-mentioned mold at work, is first carried out the reinforcement of transverse shifting bogie longeron under program by feed device
Plate, while mold is also vertically moved under program with oil pressure bed piece, the two coordinates bogie longitudinal beam reinforcing plate
The hole of selected punching be accurately positioned.Then the oil cylinder of numerical-control oil press declines, and at this moment stripper 4 is pressed in bogie longeron and adds
Bogie longitudinal beam reinforcing plate is compressed on strong plate.
Under program, it waits for that the small cylinder 10 corresponding to the hole of punching is run, stretches out piston rod and baffle 15 is pushed to cover
The upper plate 18 of punch 14.Hydraulic press pushes cope plate 2 later, and the pushing of punch 14 is made to be punched out.In addition to this step needs
Carry out punching press punch 14 outside, the small cylinder 10 corresponding to other punches 14 do not work allow its corresponding punch 14 can by
In the quick condition that can rise to 6 groove of fixed plate when pressure.Length of the punch 14 from 4 exposed portion of the stripper
Degree is not more than the thickness of the baffle 15, thus these punches 14 can cannot be rushed in compression retraction to the hole of stripper 4
It cuts.Those are coordinated the punch work for completing corresponding steps by the punch 14 that baffle 15 blocks with concave template 3.
After the completion of punching, oil cylinder rises, while the piston rod of small cylinder 10 is drawn back by electric control part driving, this makes baffle
15 are detached from the top surface of punch 14, and the punch 14 in this way is in off working state, and if compression punch 14 can rise, lower end can contract
Into the hole of the stripper 4.Big cylinder 1 is activated later, and the piston rod of big cylinder 1, which pushes stripper 4 to move down, keeps mold de-
Material.Feed device continues feeding to the hole for being punched next section thereafter.
When the hole of punching another kind shape, bogie longitudinal beam reinforcing plate transverse shifting, mold is with oil pressure bed piece longitudinal direction
After being accurately positioned to the hole of another shape, under program, 10 piston rod of small cylinder corresponding to the hole of another shape
It pushes baffle 15 to cover the top surface of punch 14, the pushing of punch 14 is made to be punched out.And so on, small cylinder is controlled by program
10 piston rods push and draw back plate washer and automatically switch punch 14, it can be achieved that a secondary piercing die can punching 10-20 kinds hole to realize
Diameter or the different hole of hole shape.
