In the description of the present invention, unless there is an explicit limitation, the words such as setting, installation, connection, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in combination with the specific contents of the technical solution.
Referring to fig. 1, a material returning mechanism mainly comprises a fixed male plate 1, an elastic buffer 2 and a push plate 3. The bottom of the male plate 1 is provided with a first accommodating hole, which is processed upwards to be a blind hole or a through hole and is used for accommodating the elastic buffer 2. The elastic buffer 2 is connected between the fixed male plate 1 and the push plate 3, the top end of the elastic buffer 2 is accommodated in the first accommodating hole, and the bottom end of the elastic buffer 2 abuts against the top of the push plate 3. When the first containing hole penetrates through the fixed male plate 1, the top of the fixed male plate 1 is fixedly connected with a top plate 5, and when the push plate 3 is pressed, the top of the elastic buffer 2 directly contacts the top plate 5. When the push plate 3 receives the packing force, the push plate 3 compresses the elastic buffer part 2, the elastic buffer part 2 converts the received force into elastic potential energy due to elasticity, and when the push plate 3 does not receive the packing force any more, the elastic buffer part 2 gives the push plate 3 resilience force, so that the push plate 3 is pushed out outwards relative to the fixed male plate 1. Change the screw hole into first holding hole, during first holding hole was put into to elastic buffer 2 to make elastic buffer 2 can not receive the influence of screw when compressing tightly, direct butt blind hole bottom surface or roof 5 have increased elastic buffer 2's mountable length, have reduced elastic buffer 2's compressive capacity, have prolonged elastic buffer 2's life, reduce manufacturing cost. This elastic buffer 2 is convenient for install and change, has saved screw fitting installation step, has reduced the labour, has improved efficiency, reduces the processing cost.
Preferably, a second accommodating hole is processed at the top of the push plate 3, the second accommodating hole is processed to be a blind hole, and the bottom end of the elastic buffer 2 is accommodated in the second accommodating hole. The bottom of the elastic buffer part 2 is provided with a guide bearing, so that the pressing force of the elastic buffer part 2 is ensured to be axial, the oblique stress of the elastic buffer part 2 is avoided, the mountable length of the elastic buffer part 2 can be increased to a certain extent, the compression amount of the elastic buffer part 2 is reduced, and the service life of the elastic buffer part 2 is prolonged.
Preferably, the first receiving hole penetrates through the fixed male plate 1, and a predetermined gap is formed between the top of the elastic buffer 2 and the top plate 5 or the elastic buffer is in direct contact with the top plate. When direct contact between the top of elastic buffer member 2 and roof 5, can avoid sliding of push pedal 3 in stamping process, the mould structure is compacter firm, and elastic potential energy can be stored to elastic buffer member 2 direct atress during the punching press.
When a predetermined gap is formed between the top of the elastic buffer 2 and the top plate 5, the height of the predetermined gap is smaller than the thickness of the solid male plate 1. The clearance setting is predetermine less in general, both can guarantee that elastomeric damper 2 increases certain length, can realize machining error's compensation again, avoids appearing the problem of assembly interference because of elastomeric damper 2 length overlength or the thickness undersize of solid public board 1.
Preferably, this first holding hole left and right sides symmetry processing, 3 atresss of push pedal are even when guaranteeing the mould punching press, and the steadiness of reinforcing mould structure sets up the punching press power that a plurality of elastomeric cushioning spare 2 can evenly distributed lathe, has improved the life of whole elastomeric cushioning spare 2, has reduced manufacturing cost.
Preferably, the elastic buffer 2 is a high-strength rubber. The high-strength rubber has the characteristics of buffering, silencing, damping, wear resistance, high temperature resistance, good strength, small compression deformation and the like, and meets the requirements of the material returning mechanism on the elastic buffer part 2.
Preferably, the elastic buffer 2 has a cylindrical shape. The first containing hole is convenient to process and integrally install.
An automatic material returning die mainly comprises a lower die, an upper die base, a push rod, a convex die plate, a convex die and a material returning mechanism. The convex template is positioned below the push plate 3, the convex die is positioned below the convex template, the push rod penetrates through the convex template to be connected with the convex die and the push plate 3, and the height of the push rod is greater than that of the convex template, so that the convex die and the convex template can move relatively, and material returning of workpieces is realized. The upper die base is provided integrally with the top plate 5. When automatic material returned mould carries out the punching press, go up mould and lower mould and close the membrane, the terrace die compresses tightly with the convex die board, and push rod promotion push pedal 3 compresses tightly elastic buffer 2, and during the die sinking, go up mould and lower mould separation, elastic buffer 2 gives 3 resilience forces of push pedal, and push pedal 3 outwards pushes away the terrace die through the push rod, realizes this automatic material returned mould autosegregation work piece.
Specifically, this automatic material returned mould still includes guide pillar 4, and this guide pillar 4 sets up between last mould and lower mould, and this guide pillar 4 symmetry sets up the extreme angle department at this automatic material returned mould. So that the die is convenient to install and guides the upper die and the lower die to be closed in the correct position.
