Position of 91 upper end of directing plate far from mold is fixedly connected with connecting plate 94 using bolt, 94 lower end surface two sides of connecting plate respectively with One piece of clamping plate 92 is hinged, and the one end of clamping plate 92 far from its hinge joint is abutted with 91 side of directing plate respectively, and third spring 93 both ends of the surface hook with the upper end of one piece of clamping plate 92 hold respectively, are located at the one end of clamping plate 92 far from its hinge joint.Into When row feeding, when the prefabricating plate 51 of punching machine 1 is abutted with material strip, sliding block 42 is directed away from lower die holder 12 under the driving of main shaft Direction is mobile, and material strip is limited by prefabricating plate 51 and will not be moved at this time, is detached from later when prefabricating plate 51 rises with material strip When abutting, sliding block 42 is mobile towards 12 direction of lower die holder under the action of the elastic force that second spring 413 applies, and material strip is clamped The frictional force that plate 92 and directing plate 91 apply jointly is mobile towards mold direction, is no longer needed at this time using manually by material strip and branch Fagging 43 compresses, and reduces the labor intensity of operator.

As shown in Figure 10, material strip is clamped since clamping plate 92 only relies on frictional force with directing plate 91, material strip and clamping plate Relative movement can be still generated between 92, to influence the charging of material strip.Therefore clamping plate 92 is uniform close to the end face of directing plate 91 Body formed to have block 921, block 921 offers lozenges 922 close to the end face of bootstrap block, and lozenges 922 is close to clamping plate One end of 92 hinge axes is tilted towards the direction of clamping plate 92.During material strip is mobile towards mold, support plate 43 It is first mobile far from mold direction, the power perpendicular to lozenges 922 that clamping plate 92 is applied by connecting column at this time, clamping plate 92 with Directing plate 91 is disconnected from each other, when the effect for the elastic force that block 921 applies with clamping plate 92 when connecting post separation in third spring 93 Lower mobile towards directing plate 91, block 921 is abutted close to the end face of mold with connecting column, and then support plate 43 is mobile towards mold It drives material strip mobile, relative movement will not be generated between material strip and clamping plate 92, to keep the use of limiting mechanism 4 more steady It is fixed.

As shown in Figure 3 and Figure 4, since the length of connecting column is longer, connecting column once can not be subjected to punch forming, therefore Thimble 23 includes two first flexible needles, 232, two second flexible needles 233 and the flexible needle 234 of two thirds.Link block 231 is Three pieces, lower end is welded with the first flexible needle 232 or two second flexible needles 233 or the flexible needle 234 of two thirds.With it is same The the first flexible needle 232 or two second flexible needles 233 or the flexible needle 234 of two thirds that block link block 231 connects are set side by side, And its length is successively increased along feedstock direction, diameter is sequentially reduced along feedstock direction.The quantity of female die block 32 is three pieces, thereon End offers two cooperated with two first flexible needles, 232, two second flexible needles 233 and the flexible needle 234 of two thirds respectively 321, two the second telescopic holes 322 of a first telescopic hole and two third telescopic holes 323.By the way that the diameter of thimble 23 is gradually dropped Low, length gradually increases, to make connecting column that can gradually form, deformation is excessively acutely generated broken when material strip will not be because of molding Damage increases stability when mold uses.

As shown in figure 3, the sky of connecting column can be made when stamp mould 24 is abutted with stamp block 33 since there are air in connecting column Air pressure contracting, deforms so as to cause connecting column, influences the quality of button.Therefore 24 lower end of stamp mould coaxially offers gas vent 241,241 other end of gas vent runs through 24 side wall of stamp mould.The air in connecting column is discharged using gas vent 241, thus So that the air pressure in connecting column is not changed, connecting column is made not deform.

As shown in Figure 3 and Figure 4, since the diameter of molding button can change, at this time thimble 23, female die block 32, print Relative position between embossing die 24 and stamp block 33 can change, therefore 2 lower end of upper mold is offered along feedstock direction extension Upper regulating tank 26, link block 231 and stamp mould 24 can be placed in sliding in link slot 612.One side of upper link slot 612 Through there is upper abutting slot 27, be equipped in upper abutting slot 27 four it is upper abut bolts 28, upper abutting bolt 28 respectively with link block 231 and stamp mould 24 be threadedly coupled, and its nut is abutted with 2 side wall of upper mold.3 upper end of lower die offers corresponding with upper regulating tank 26 Lower regulating tank 36, female die block 32 and stamp block 33 are placed in sliding in lower regulating tank 36.Lower 36 one side wall of regulating tank, which runs through, to be had Lower abutting slot 361 is worn in lower abutting slot 361 there are four lower abutting bolt 362, lower abutting bolt 362 respectively with female die block 32 Or stamp block 33 is threadedly coupled, nut is abutted with 3 side wall of lower die.To need the diameter for the button processed to change When, the spacing between adjacent link block 231 and adjacent female die block 32 is adjusted, to make mold that can continue to process button.

As shown in figure 4, material strip is needed when moving by connecting column and female die block 32 after stamping out connecting column due to material strip It is disconnected, can just continue to feed at this time.Therefore 3 upper end of lower die is connected with lifting block 371, and it is separate that lifting block 371 is located at lower die 3 One end of hold-down mechanism 6.For lifting block 371 close to the end face of lower die 3 through there is two connectivity slots 372, connectivity slot 372 will be lifted block 371 upper ends are run through and connecting column can pass through in connectivity slot 372.After after connecting column has formed, since material strip both ends are distinguished Be connected block 231 and support plate 43 to be lifted, therefore material strip restores level under the action of the elastic force of itself, at this time connecting column with it is recessed Module 32 is disconnected, and connecting column can proceed with feeding at this time.

As shown in figure 4, due to material strip during processing its can generate bending, will affect the matter of the button of processing at this time Amount, therefore 3 upper end of lower die offers lifting slot 37, lifting block 371 can be placed in lifting slot 37 and slide up and down, be lifted in slot 37 and set It is equipped with lifting spring 373, the upper end for being lifted spring 373 is abutted with lifting 371 lower end of block, and lower end is supported with lifting 37 bottom surface of slot It connects.When carrying out the molding of button, prefabricating plate 51 is abutted with lifting 371 upper end of block, makes to move in its direction lifting slot 37, at this time Material strip will not generate bending in horizontally disposed, be lifted that block 371 is no longer influenced by that preloading block applies after completing punching press downwards Power applies upward elastic force to lifting block 371 using lifting spring, makes lifting block 371 that material strip be driven to move up, connecting column can It is detached from the connection with female die block 32.

In order in the unformed connecting column of punching press, molded connecting column will not be squeezed because of by upper mold 2 and lower die 3 It presses and is deformed.As shown in figure 4, lower die 3 offers two for accommodating the passage of connecting column away from the end face of feed direction Slot 38, current groove 38 run through 3 plate upper surface of lower die, and it is connected to lower regulating tank 36 and lifting slot 37.To in prefabricating plate 51 and lower die 3 abut when, molded connecting column can be placed in current groove 38, and connecting column will not deform, to make mold Use it is more stable.

As shown in Figure 10, after being changed due to the diameter of button, the position meeting of material strip connecting column when being punched out It changes, therefore the mounting groove 913 having in waist type is run through in 91 upper end of directing plate, the length direction of mounting groove 913 is parallel to material The moving direction of band, installation bolt 911 are threadedly coupled across mounting hole support plate 43, so that the diameter in the button of processing occurs After change, it can adjust the position of gripping block, abut baffle can still with connecting column, so as to drive material strip mobile.

In order to keep the connection between material strip and clamping plate 92 and directing plate 91 more firm, as shown in Figure 10, clamping plate 92 End face close to directing plate 91 offers the second guiding groove 923, and the second guiding groove 923 is by 92 lower end surface of clamping plate and opposite Two sides are run through, and material strip can be placed in the second guiding groove 923.Material strip is limited using the second guiding groove 923, makes material strip not Distortion can be generated upwards and be detached from the connection with clamping plate 92, to keep the use of feeding device more stable.
