Description
Technical field
The utility model relates to a kind of die backing plate that old money mould height of packing compact is not enough, binding clasp can't clamp automatically and mould is eccentric that is used to solve.
Background technology
In recent years, along with the punching automation line the applying of each big automobile main frame maker, improved stamping production efficiency to a great extent.The punching production mode is changed to the automation mode by manual mode.The robot line of domestic main flow such as COMAU, ABB, KUKA etc., because flexible higher, running orbit point coordinates alterability is big, and is very high in punching automation initial stage applicability.Along with the production lot increasing of main engine plants' punching press, production efficiency is also wanted corresponding raising, and the SPM of robot line has only 5～10 times, can not satisfy development trend, and therefore original robot automation's line has begun to change to high-speed line.The generation of high-speed line has fundamentally changed the inefficient state of robot line, but also the structure (such as the aspects such as uniformity at height of packing compact, mold center and press center) of mould is had higher requirement simultaneously.
With the auto production line is example, and at present, a lot of old vehicle moulds do not require design according to high-speed line, and main problem has the mould height of packing compact not enough, and mold center departs from the press center.Usually solving the not enough method of height of packing compact is to add backing plate at counterdie; But traditional backing plate can not solve the problem that can't clamp owing to the eccentric pressing plate groove that brings of mould; Therefore solve pressing plate groove clamping problem and just on die ontology, process again, cause the transformation of mould to bother very much.
Summary of the invention
The purpose of the utility model be propose a kind of simple in structure, cost is low, manufacturings is simple, easy to operate, locate reliable die backing plate, with solve the mould height of packing compact inadequately and mold center depart from press central issue.
The die backing plate of the utility model comprises tabular main body, and key is that the position of center line of said main body is provided with keyway, and the sidepiece of main body is provided with many U-shaped elongated slots that are arranged in parallel, and said main body is provided with the adjustment chute at the end face at the blind end place of U-shaped elongated slot.
In use, die backing plate is stacked on the press with mould,, guarantees that height of packing compact satisfies the press requirement to improve the height of packing compact of mould.When automatic binding clasp can't clamp automatically, can compensate the not enough problem of automatic binding clasp stroke through the U-shaped elongated slot; When mould off-centre surpasses the press instructions for use, through adjusting the width corresponding relation that chute can change mould and die backing plate, mould is alignd with die backing plate, guarantee adjusted clamping precision, thereby remedy the eccentric difference of mould on press; In addition, the keyway of position of center line can remedy the unbalance loading distance, with the installation site that guarantees mould in press unbalance loading scope allowable.
Further, for easy to adjust, said keyway has two, is arranged at position of center line and the position of center line of principal length direction of the width of main body respectively.
Further, for enlarging adjusting range, the two ends of said keyway extend to the edge of main body.
Further, for guaranteeing to step up, said U-shaped elongated slot is symmetrically distributed in the dual-side of the length direction of main body.
The required member of the die backing plate of the utility model is few, operability reliable, but the accurate positioning generalization is high; Be highly suitable for not traditional moulds transformation project by high-speed line requirement design; To guarantee that traditional moulds satisfies the requirement of high-speed line mould under the prerequisite of processing again, save the cost of corporation improvement punching automation line.

The specific embodiment
Contrast accompanying drawing below; Through description, the effect of the mutual alignment between the shape of the specific embodiment of the utility model such as related each member, structure, the each several part and annexation, each several part and operation principle etc. are done further to specify to embodiment.
Embodiment 1:
Shown in Fig. 1～4, the die backing plate of present embodiment comprises tabular main body 1, and the position of center line of the position of center line of the width of main body and principal length direction respectively is provided with a keyway 2, and the two ends of keyway 2 extend to the edge of main body 1; The dual-side of the length direction of main body 1 is provided with many U-shaped elongated slots 3 that are arranged in parallel, and the end face of main body 1 at the blind end place of U-shaped elongated slot 3 is provided with adjustment chute 4.
Concrete size in the face of die backing plate describes down:
To the not enough problem of big part mould height of packing compact, high-speed line requires more than the 1200mm, and the height of packing compact of supposing mould is A (A < 1200mm), and then the thickness minimum of die backing plate is: (1200-A) mm.
Can't clamp problem automatically to smallclothes mold cramping device; The width of press bed is 2500mm, and the travel distance of binding clasp is automatically: max800mm, and the width of supposing mould is B; If B < (2500-2*800) mm=900mm; Then the minimum widith of die backing plate is 900mm, if B>900mm, then the minimum thickness of die backing plate is B.
The length of die backing plate is identical with die length.
The structure of U-shaped elongated slot extends on the basis of U-lag, and the length of side of U-shaped elongated slot can be selected for use: 280mm-380mm, and for the integral multiple of 10mm is processed.
The adjustment chute is an oblong slots, and width value is chosen 80mm, 90mm, 100mm, and length value is chosen 250mm, 260mm, 270mm.
To the eccentric problem of mould, confirm the position (being made as X) of backing plate central channel according to the distance at mold center and press center, the die backing plate position after reorientating should guarantee that the installation site of mould is in press unbalance loading scope allowable.The concrete unbalance loading scope that allows is fixed according to press specification design specification; Angle from producer's apolegamy press tonnage; According to the 75% sizable principle of required plastic force P of mould and press nominal pressure Pg, confirm that plastic force P allows the distance A 0 of unbalance loading, and then draw mould and need satisfy: X < A0.If X>A0, the mould unbalance loading exceeds the press instructions for use, and at this moment, distance (X-A0) is remedied by die backing plate keyway 2.
In use, die backing plate is stacked on the press with mould,, guarantees that height of packing compact satisfies the press requirement to improve the height of packing compact of mould.When automatic binding clasp can't clamp automatically, can compensate the not enough problem of automatic binding clasp stroke through the U-shaped elongated slot; When mould off-centre surpasses the press instructions for use; Can change the width corresponding relation of mould and die backing plate through the adjustment chute; Mould is alignd with the broadside of die backing plate, guarantee adjusted clamping precision, thereby remedy the eccentric difference of mould on press; In addition, the keyway of position of center line can remedy the unbalance loading distance, with the installation site that guarantees mould in press unbalance loading scope allowable.
Combine accompanying drawing that the utility model has been carried out exemplary description above; Obviously the utility model practical implementation does not receive the restriction of aforesaid way; As long as adopted the method design of the utility model and various improvement that technical scheme is carried out to be applied to other occasions, all within the protection domain of the utility model.
