Detailed Description
In order to facilitate the understanding of the technical solutions of the present invention for those skilled in the art, the technical solutions of the present invention will be further described with reference to the drawings attached to the specification.
As shown in fig. 1 to 3, the rigid protection device for a stamping die according to the technical solution of the present invention includes a plurality of rigid stoppers 2 mounted on a lower die base 1 for supporting an upper die. In fig. 1, the rigid retainer at a is in an operating state, that is, the rigid retainer is in a state of supporting the upper die. In the figure 1, the rigid limiter at the position B is in a downward-placing state, namely, the rigid limiter rotates to the outer side of the lower die base, the upper space of the lower die is made away, and the upper die can be normally closed. For convenience of observation and comparison, two states of the upper rigid retainer are shown in fig. 1, and of course, in the operation of the rigid retainer, since the supporting state and the lowering state of the rigid retainer are both realized by manual operation, the states of the rigid retainers can also appear as shown in fig. 1.
As shown in fig. 1 to 3, in the present embodiment, the rigid retainer 2 includes a support column 21 rotatably connected to the lower die base 1. When the mould is deposited, support column 21 supports last mould, avoids last mould and the long-time compound die of lower mould, influences the lower mould clearance to and elastomeric element's elasticity and life in the mould, support last mould through the support column, ensure the clearance and the size precision of mould, extension mould life. When the die works, the supporting column 21 rotates towards the outer side of the lower die holder 1 to give way the upper space of the upper die, so that the die can normally close the die conveniently, and through the arrangement of the signal control assembly, the die closing operation can be carried out only after all the rigid limiters rotate out of the die, and the dual protection of the die and the rigid limiters is realized.
As shown in fig. 1 to 3, in the present technical solution, a hinge block 22 is connected to a side surface of the support column 21 facing the exterior of the lower mold, the hinge block 22 is hinged to the exterior side surface of the lower mold, and the support column 21 rotates toward the exterior side surface of the lower mold base 1. As shown in fig. 2, the hinge block 22 is arranged to enable the support column 21 to stand on the upper surface of the lower die holder 1 completely when supporting the upper die, so that the support column 21 and the lower die holder 1 are stressed uniformly. When the support column rotates towards the outer side surface of the lower die holder 1, the support column can completely rotate out of the upper surface of the lower die holder 1, and the phenomenon of interference between the support column and the lower die holder and between the support column and an upper die is avoided.
As shown in fig. 2 and 3, in the present embodiment, the rigid retainer 2 further includes a signal control assembly. The signal control assembly comprises a limiting inductor 24 arranged on the outer side surface of the lower die holder 1, when the supporting column 21 rotates to the outer side surface of the lower die holder 1, the supporting column contacts the limiting inductor 24, the limiting inductor 24 is electrically connected with the terminal box 3, and the terminal box 3 is in signal connection with the die control system. In the technical scheme, the automatic intelligent connection between the state of the rigid stopper 2 and the mold control system is realized through the signal control assembly. After support column 21 rotated out, trigger spacing inductor 24, spacing inductor 24 is connected with 3 electricity on the terminal box, signal transmission to mould control system or lathe system that terminal box 3 rotated out support column 21, triggered when all spacing inductors 24, mould control system could control mould compound die, work, when the effectual support column 21 of having avoided still is in between last mould and the lower mould, go up mould compound die operation, lead to the fact the problem of damage to the support column, cause the incident problem.
In the technical scheme, the signal control assembly is arranged, and the problem of misoperation of an upper die or a machine tool and the like when the rigid limiters 2 do not rotate out completely is effectively solved by connecting and controlling signals of all the rigid limiters 2. When at least one rigid limiter 2 is not put down, the die control system cannot start and control the die or the machine tool to work, so that the safety production accident caused by the fact that the press machine moves downwards to crush the die or fly out is avoided.
As shown in fig. 2 and 3, in the present technical solution, a groove 23 is disposed on a side surface of the lower die holder 1, and the limit sensor 24 is disposed in the groove 23 and an end portion of the limit sensor does not extend out of a groove opening portion. And a convex limiting clamping plate 25 is arranged on the side surface of the support column 21 close to the outer side surface of the lower die base. When the support column 21 is rotated outward onto the outer side face, the limit catch plate 25 contacts the limit sensor 24. The arrangement of the groove protects the limit inductor 24, prevents the limit inductor 24 from protruding outwards and touching mistakenly, and further ensures the reliability of the signal control assembly.
Among this technical scheme, support column 21 is the square steel, and articulated piece 22 is the form of bending and includes the connecting block and extends the piece, and the connecting block and extend between the piece contained angle be the obtuse angle, connecting block and support column side welded connection, and the terminal surface that the connecting block was kept away from to the extension piece is articulated with the die holder. The arrangement of the hinge block 22 in a bent shape enables the support column 21 to stand on the upper surface of the lower die holder 1 completely when supporting the upper die, so that the support column 21 and the lower die holder 1 are stressed uniformly. When the support column rotates towards the outer side surface of the lower die holder 1, the support column can completely rotate out of the upper surface of the lower die holder 1, and the phenomenon of interference between the support column and the lower die holder and between the support column and an upper die is avoided. A hinged seat 26 is fixed on the outer side surface of the lower die seat, and the extension block is hinged with the hinged seat 26. The setting of articulated seat 26 has realized providing the position for the articulated installation of support column on the one hand, and on the other hand realizes protecting the die holder, avoids appearing the impaired problem of die holder.
In the technical scheme, the rigid limiters 2 comprise four groups, and four vertex angles of the lower die holder 1 are uniformly distributed. The rigid limiters 2 are symmetrically and uniformly distributed, so that the lower die holder is stressed uniformly, and the upper die holder is supported stably.
Technical solution of the utility model the present invention is described above with reference to the accompanying drawings by way of example, and it is to be understood that the specific implementation of the present invention is not limited to the above-described embodiments, and it is within the scope of the present invention to employ various insubstantial modifications of the method concept and technical solution of the present invention, or to directly apply the concept and technical solution of the present invention to other applications without modification.
