Specific embodiment
In the description of the present invention, it should be understood that the orientation or positional relationship of the instructions such as term " on ", "lower"
To be based on the orientation or positional relationship shown in the drawings, it is merely for convenience of describing the present invention and simplifying the description, without referring to
Show or imply that signified device or element must have a particular orientation, be constructed and operated in a specific orientation, therefore cannot manage
Solution is limitations of the present invention.
Combined with specific embodiments below, the content of the utility model is described in further detail, Fig. 2 shows this realities
With the structural schematic diagram of novel middle pressing and bending mold, it is made of several parts such as upper mold 1, lower die 2 and bending mechanisms 3, wherein
Upper mold 1 includes upper die holder 11 and the pressure plate 12 being set to immediately below it.Lower die 2 includes lower die holder 21 and is set to right above it
Cavity plate 22.Bending mechanism 3 is set in upper mold 1 comprising braking push piece 31 slides stamping parts 32, guide holder 33 and returns
Multiple spring 34.Braking push piece 31 is fixed on upper die holder 11.Guide holder 33 is embedded in pressure plate 12.Offered in pressure plate 12 with
The compatible tilting through-hole of 32 shape of stamping parts is slided, and the lower openings of the tilting through-hole are corresponding with the cutting edge of cavity plate 22.
Ring-shaped step is set in tilting through-hole, for abutting against returning spring 34, and is sheathed on the periphery of sliding stamping parts 32.It is sliding
The lower end of stamping parts 32 is provided with bending part 321.The pressing and bending mold actions process is as follows: 1) flitch being placed in lower die
2, and make it that there is accurate relative position relative to cavity plate 22；2) upper mold 1 is moved downwards relative to lower die 2, until pressure
Flitch 12 compresses flitch；3) upper die holder 11 continues to push, so that sliding stamping parts 32 abuts against the work of power in braking push piece 31
It is slided under along tilting through-hole, and then the bending (as shown in Figure 5) to flitch is realized by bending part 321.
Above-mentioned technical proposal beneficial effect most outstanding is: in practical bending process, sliding the work of stamping parts 32
Face corresponds to the side wall of cavity plate 22 always, and the bending process of flitch is completed by means of the side wall of cavity plate 22, so as to avoid expecting
Plate is squeezed, and reduces materials and parts folding surface front stress, so that flitch surface be avoided curved moulding mark occur, improves the molding of product
Quality.
As advanced optimizing for above-mentioned pressing and bending mold, the bending part 321 for being set to sliding 32 end of stamping parts is excellent
It is selected as arc-shaped (as shown in Figure 3), on the one hand, advantageously reduce its frictional force relative to flitch；On the other hand, it prevents from rolling over
Turn of bilge 321 scratches flitch.It should be noted that showing that the arc radius of bending part 321 is not preferably less than by many experiments
The thickness of 3 times of flitch.
For structure design and reduce braking push piece 31 abut against power two from the aspect of, in pressing and bending disclosed above
In mold, the tilting through-hole tilt angle relative to horizontal direction for being oriented to sliding stamping parts 32 is preferably controlled
120~150 °, optimal value is 135 °.
Furthermore in order to reduce the relative friction forces of sliding stamping parts 32 and tilting through-hole, rate of depreciation is reduced, it can also be
It slides and is respectively provided with wear-resistant coating on the outer wall of stamping parts 32 and the inner wall of tilting through-hole.The preferred TiC coating of wear-resistant coating, tool
There is higher hardness and wear resistance, inoxidizability might as well.
Idler wheel 311 (as shown in Figure 4) is hinged in the lower end of braking push piece 31.When braking push piece 31 is moved downwards
When dynamic, idler wheel 311 is freely rolled relative to the end of sliding stamping parts 32.It is configured by using above scheme, to make
The movement matching relationship that push piece 31 and sliding stamping parts 32 must be braked is changed into rolling friction by sliding friction, and then reduces the two
Rate of depreciation, reduce pressing and bending mold frequency of maintenance.As further optimization, make to reduce braking push piece 31
For sliding the instantaneous impact of stamping parts 32, the damage rate of reduction by 311 hinged place of idler wheel can also be in the outer wall of idler wheel 311
Wrap up plastic layer.
Certainly, from the aspect of simple for structure, the lower pressure surface inclination that will can be directly set to braking 31 lower end of push piece be set
It sets, and tilt angle is parallel with the sliding upper end working face of stamping parts 32.Preferably, above-mentioned lower pressure surface is relative to level side
To tilt angle preferably control at 30~60 °.
The foregoing description of the disclosed embodiments can be realized professional and technical personnel in the field or using originally practical new
Type.Various modifications to these embodiments will be readily apparent to those skilled in the art, and determine herein
The General Principle of justice can be realized in other embodiments without departing from the spirit or scope of the present utility model.Cause
