Specific embodiment
Exemplary embodiments of the present disclosure are described in more detail below with reference to accompanying drawings.Although showing the disclosure in attached drawing
Exemplary embodiment, it being understood, however, that may be realized in various forms the disclosure without should be by embodiments set forth here
It is limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the scope of the present disclosure
It is fully disclosed to those skilled in the art.
See Fig. 1, the negative angle forming mechanism of the present embodiment is made of conventional upper die holder 1 and lower die holder 2,2 top of lower die holder
Central location there is cavity plate 21, protrusion 211 is equipped in the left and right sides edge of 21 top surface of cavity plate, to realize cavity plate 21
Indent in the middle part of top surface, the central location of 1 bottom of upper die holder have the punch-pin 11 opposed with cavity plate 21, and punch-pin 11 and cavity plate 21 are mutual
It is opposed with by 5 punch forming of embryo material in Fig. 2.
Due to the present embodiment negative angle forming mechanism be one go out two molds, at left and right sides of structure be substantially the same, only
Slight difference on position, but the course of work and principle are essentially identical, to simplify full text, hereafter only describe negative angle forming mechanism
Right side structure, the left side structure reference of negative angle forming mechanism.
In order to synchronize to form negative angle in punching press embryo material 5, the right side of cavity plate 21 is equipped with horizontal material lift plate in the present embodiment
3,3 bottom of material lift plate is fixed on lower die holder 2 by the first cylinder 31, wherein 31 vertical display of the first cylinder and passing through screw fastening
Tightly in 2 top surface of lower die holder, the pistons end of the first cylinder 31 is bolted 3 bottom of material lift plate, and material lift plate 3 is in the first gas
Under the driving of cylinder 31, realization is moved up and down.
The top of material lift plate 3 is equipped with hinged block 32 close to the side of cavity plate 21, is provided with and is not shown in the figure in the middle part of hinged block 32
Strip groove, lower material folding block 33 is towards close to the inclined state in 21 direction of cavity plate (i.e. in Fig. 1 lower material folding block shown in state)
It is placed in the strip groove, and by rotary shaft 321 come hinged with strip groove.The bottom of lower material folding block 33 is towards far from cavity plate
21 direction is laterally protruding to form handle 34, and handle 34 is also heeling condition, and the shape folder in 90 ° between lower material folding block 33
Angle, in this way, lower material folding block 33 can be made to be rotated centered on rotary shaft 321, make it from inclination by squeeze grip 34 downward
State turns to vertical state (i.e. state shown in lower material folding block in Fig. 3), to realize the lift action of lower material folding block 33.Under
When material folding block 33 turns to vertical state, side wall is located at same straight line with the side wall of cavity plate 21 just.Further, lower material folding
In an inclined state, top is a horizontal plane 331 to block 33, when the rotation of material folding block 33 instantly becomes vertical state, horizontal plane
331 become inclined state.
In order to lift the lower rotation of material folding block 33 during upper die holder 1 pushes, the right side of punch-pin 11 is equipped with horizontal take off
Flitch 4, the top of stripper plate 4 are fixed on upper die holder 1 by the second cylinder 41, wherein 41 vertical display of the second cylinder and passing through
For screw-threaded coupling in 1 bottom surface of upper die holder, the pistons end of the second cylinder 41 is bolted 4 top of stripper plate, and stripper plate 4 exists
Under the driving of second cylinder 41, realization is moved up and down.
The bottom of stripper plate 4 is fixedly installed with upper material folding block 42, the bottom tool of upper material folding block 42 close to the side of punch-pin 11
Have when becoming vertical state towards close to the inclined inclined surface 421 in 11 direction of punch-pin, material folding block 33 is lifted instantly, inclined surface 421 with
Horizontal plane 331 after rotation is parallel, so that embryo material 5 is clamped between the two.To realize lifting for lower material folding block 33, stripper plate
4 bottom is further fixed on to top pillar 43, is set to the surface of handle 34 to top pillar 43 to be directed at handle 34, bottom is lower than upper
The bottom of material folding block 42, in this way, during upper die holder 1 pushes, the leading squeeze grip 34 in the bottom of top pillar 43, to make lower folder
Material block 33 lifts the embryo material 5 that will be placed on originally on horizontal plane 331 and is pressed on the inclined surface 421 of upper material folding block 42, thus real
Now to the clamping of embryo material 5.Embryo material 5 is difficult to slide when clamping embryo material 5 to ensure, teeth 332, inclination are arranged on horizontal plane 331
The recess position (not shown) being embedded in for teeth 332 is correspondingly arranged on face 421, with the occlusion when clamping through teeth 332
Effect ensures that embryo material 5 is difficult to slide.
When carrying out the negative angle forming of embryo material 5, the course of work of the negative angle forming mechanism of the present embodiment is as follows:
Fig. 1 show negative angle forming mechanism it is initial when die opening state, in this state, the first cylinder 31 is by material lift plate 3
The top surface for being raised up to lower material folding block 33 is higher than the top bump 211 of cavity plate 21, so that the space between two pieces of lower material folding blocks 33 is high
Cavity plate 21 out, this just provides for finger feed and keeps away bit space, and manipulator can keep away bit space for embryo material 5 shown in Fig. 2 through this
It is sent on the horizontal plane 331 of lower 33 top surface of material folding block, at this time since lower material folding block 33 not yet lifts, top surface keeps horizontal, embryo
Material 5 is able to lay flat on it.
After the completion of feeding, upper die holder 1 is pushed, the intermediate state of Jian Tu3 negative angle forming mechanism, and top pillar 43 is first during pushing
It goes and is pressed into handle 34, lift lower material folding block 33 and become vertical state, descend material folding block 33 by the embryo on horizontal plane 331 after lifting
Material 5 is pressed on the inclined surface 421 of material folding block 42, so that embryo material 5 becomes Fig. 4 state by Fig. 2 state.
See Fig. 3, hereafter upper die holder 1 continues to push, and the first cylinder 31 and the second cylinder 41 start stress, but the second cylinder 41
The first cylinder of driving force ratio 31 it is big so that the first cylinder 31 first starts to sink, so that material lift plate 3 be driven to sink.
Material lift plate 3 is killed after sinking down into 2 top surface of lower die holder, the top protrusion with cavity plate 21 just of this material folding block 33 at present
211 flush, and hereafter upper die holder 1, which continues to push, makes the second cylinder 41 increase stress, and stripper plate 4 is moved up relative to punch-pin 11, so that
Punch-pin 11 stretches out between two pieces of upper material folding blocks 42, and pushes embryo material 5 to the indent position being embedded into the middle part of 21 top surface of cavity plate, until
This completes the die closing of negative angle forming mechanism, and closed mode state as shown in Figure 5 is presented in negative angle forming mechanism at this time.In closed mode state
Under, since the left and right sides edge of 21 top surface of cavity plate has protrusion 211, embryo material 5 is pressed onto the middle part of 21 top surface of cavity plate by punch-pin 11
When indent position, moulding is carried out to embryo material 5, so that it is become Fig. 6 state from Fig. 4 state, to complete the positive bending of negative angle 51
Molding.
The negative angle forming mechanism of the present embodiment by the rotation of lower material folding block 33 the negative angle forming process of product, by tradition
Sliding block lateral bending, be turned into positive bending, die space needed for conventional sliders lateral bending is greatly decreased with this, thus
Reduce mold Material Cost.
