Abstract
The invention relates to a progressive die structure for preventing a material belt from upwards jumping. The progressive die structure for preventing the material belt from upwards jumping comprises a lower die, and an upper die which is correspondingly mounted above the lower die, wherein a floating plate is transversely mounted and fixed in the middle part of the lower die; jumping stopping plates which are of rectangular structures are lengthways mounted on the lower surface of the upper die; a rectangular bump is arranged in the middle part of each rectangular structure, and rectangular grooves for storing workpieces are formed in two sides of the bumps; a lifting frame which is of a U-shaped fork structure is fixedly mounted at the tail part of a material plate. According to the progressive die structure for preventing the material belt from upwards jumping, the material belt can be prevented from upwards jumping during the step-based moving conveying through the jumping stopping plates, so that the processing quality can be ensured; a punch is cut off firstly during the blanking, and then the lifting frame is lifted up to finish the blanking, thus the workpieces can be close to the upper die and cannot be deformed during being cut off, and as a result, the yield can be effectively improved.
Description
Technical field
The invention belongs to the progressive die structure jumped on mould manufacturing field, especially a kind of anti-stopping materials strip.
Background technology
Progressive die (being also the progressive die) is made up of multiple stations, and each station associates complete different processing in order, in punch press
A series of different punch process is completed in one stroke.After one stroke is completed, by punch press feeder according to a fixation
Step pitch material is moved forward, multiple operations can be just completed so in one set of die, typically have a punching, blanking, bending,
Trimming, drawing etc..
Of both traditional progressive die be present：
1st, during feeding, because material strip is longer, thus often there is the phenomenon that material strip is jumped upwards, the generation of this phenomenon in Jing
Product quality is directly affected, the qualification rate of product is significantly reduced.
2nd, when the material tail of traditional progressive die is blanking punched, due to workpiece apart from lower template surface closely and apart from upper die plate farther out, so
Workpiece is yielding during blanking punched, significantly reduces the qualification rate of product.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art, there is provided the progressive die knot jumped on a kind of anti-stopping materials strip of simple structure
Structure.
What the solution of the present invention was realized in：
The progressive die structure jumped on a kind of anti-stopping materials strip, including lower mould and upper mould, the upper mould correspondence is arranged on lower mould top, institute
State lower mould middle part and be transversely mounted fixed buoyant plate, the lower surface of the upper mould is longitudinally mounted to stop springboard, and the only springboard is rectangle knot
Structure, its medium position is formed with rectangular preiection, and raised both sides are the rectangular recess for accommodating workpiece.
And, the afterbody of flitch is fixedly mounted with a material lift frame, and the material lift frame is U-shaped fork structure.
And, incline 1-2 degree.
And, the vertically-mounted sensor of template afterbody.
Advantages of the present invention and good effect are：
1st, the only springboard in this structure prevents from being jumped on material strip during step pitch moving feeding, it is ensured that crudy.
2nd, the drift during blanking of the material lift frame in this structure is initially switched off, and then lifts to complete blanking, and its purpose makes workpiece
Apart from upper mould compared with closely ensureing that workpiece is indeformable during cut-out, effectively increases yield rate.
3rd, the installation of sensor ensure that the accuracy of feeding in this structure.
4th, present configuration is simple, design science is reasonable, be skillfully constructed, be easily achieved, and effectively increases progressive die converted products
Qualification rate, the value with wide popularization and application.
Description of the drawings
Fig. 1 is the front view (hiding workpiece) of the present invention；
Fig. 2 is the top view of lower mould in Fig. 1；
Fig. 3 be in Fig. 1 A-A to sectional view；
Fig. 4 is the I portions enlarged drawing of Fig. 3.
Specific embodiment
Below in conjunction with the accompanying drawings and by specific embodiment the invention will be further described.
A kind of progressive die structure jumped on anti-stopping materials strip, as shown in Figure 1 and Figure 2, including lower mould 1 and upper mould 2, the upper mould
Correspondence is arranged on lower mould top, and the lower mould middle part is transversely mounted fixed buoyant plate 4, on the buoyant plate workpiece 7, workpiece are placed with
Move forward along buoyant plate, arrow completes the processing of multiple operations for the moving direction of workpiece in Fig. 2.
The present invention innovative point be：
1st, the longitudinally mounted only springboard 3 of the lower surface of the upper mould, the only springboard is rectangular configuration, as shown in Figure 3, Figure 4,
Its medium position is formed with the rectangular preiection 3A of top pressure workpiece material strip, and raised both sides are the rectangular recess 3B for accommodating workpiece.This enforcement
Only springboard in example accompanying drawing is two, is voluntarily arranged according to the actual conditions of mould.By the installation for stopping springboard, in step pitch movement
During feeding, only the rectangular preiection top pressure material strip of springboard, jumps, it is ensured that product quality on anti-stopping materials strip.
2nd, the afterbody of the buoyant plate is installed and fixes a material lift frame 5, and the material lift frame is U-shaped fork structure, and the material lift frame uses reinforcing bar
Bending is formed.After material lift frame lifts workpiece during blanking, then cut-out is completed, its purpose makes workpiece nearer apart from upper mould
Ensure that workpiece is indeformable during cut-out, effectively increases yield rate.
3rd, the vertically-mounted sensor 6 of lower template afterbody of correspondence material lift frame, after workpiece movement and touch sensor, then workpiece is no longer
Reach, direct slug, it is ensured that the accuracy of processing.For the ease of processing, the material lift frame is inclined upwardly 1-2 degree.
Advantages of the present invention effect is：
1st, the only springboard in this structure prevents from being jumped on material strip during step pitch moving feeding, it is ensured that crudy.
2nd, the drift during blanking of the material lift frame in this structure is initially switched off, and then lifts to complete blanking, and its purpose makes workpiece
Apart from upper mould compared with closely ensureing that workpiece is indeformable during cut-out, effectively increases yield rate.
3rd, the installation of sensor ensure that the accuracy of feeding in this structure.
4th, present configuration is simple, design science is reasonable, be skillfully constructed, be easily achieved, and effectively increases progressive die converted products
Qualification rate, the value with wide popularization and application.
It is emphasized that embodiment of the present invention is illustrative, rather than it is determinate, therefore the present invention is including simultaneously
The embodiment being not limited to described in specific embodiment, it is every to be drawn by those skilled in the art's technology according to the present invention scheme
Other embodiment, also belongs to the scope of protection of the invention.
