The embodiment provides an uncoiling blanking die with an elastic material supporting frame 4, which comprises an upper die 1, a lower die 2, a guide block 5, an elastic resetting device 3 and a blanking frame; elastic reset device 3 includes ejector sleeve 31 and spring 32, and ejector sleeve 31 is inside to be equipped with spring 32 nest hole to install spring 32 in spring 32 nest hole, when preventing to push down ejector sleeve 31, spring 32 controls the displacement on radial direction, makes spring 32 compress in the axis direction all the time, has guaranteed the flexible direction precision of spring 32.

In this embodiment, eight positioning holes 21 are formed in the upper end surface of the lower mold 2 for installing the spring 32 in the positioning holes 21, so that the spring 32 can extend and contract in the positioning holes 21 to achieve elastic connection between the spring 32 and the lower mold 2, and then the ejector sleeve 31 is slidably disposed on the positioning holes 21 to prevent the spring 32 from coming off.

In this embodiment, when the ejector sleeve 31 is pressed down, the spring 32 contracts to drive the ejector sleeve 31 to slide downward on the positioning hole 21; when the ejector sleeve 31 is not stressed, the spring 32 extends to drive the ejector sleeve 31 to slide upwards on the positioning hole 21.

In the embodiment, the ejector sleeve 31 is fixedly arranged on the lower end surface of the guide block 5, the blanking frame is fixedly arranged on the side end surface of the guide block 5, the lower end surface of the upper die 1 is provided with the guide part 10, when the upper die 1 moves downwards, the guide part 10 abuts against the upper end surface of the guide block 5 to drive the ejector sleeve 31 to press downwards, the spring 32 automatically contracts, and the blanking frame is in a pushing position; when the upper die 1 moves upward relative to the lower die 2, the guiding element is not stressed, the spring 32 is in an extended state, and the spring 32 drives the ejector sleeve 31 to slide upward on the positioning hole 21, so that the guiding block 5 on the ejector sleeve 31 drives the material supporting frame 4 to an initial position.

In this embodiment, due to the structural effect of the spring 32, the springs 32 on the lower die 2 have the same automatic extending distance when not stressed, so that the sliding distances of the ejector sleeves 31 can be the same; therefore, when the spring 32 is not stressed, the same balance effect of the material supporting frame 4 at the initial position can be ensured; and when holding in the palm the work or material rest 4 in the top pushes away the position, because of the balanced effect that last mould 1 itself has for when going up mould 1 and punching press down 2 lower moulds relatively, hold in the palm work or material rest 4 and also keep balance continuously.

In this embodiment, the material supporting frame 4 is formed by combining and fixedly connecting a plurality of supporting rods 41, the supporting rods 41 are combined into three hollow rectangular structures, and the supporting rods 41 are aluminum alloy sections; the four end faces of the support rod 41 are provided with T-shaped sliding grooves 411, and the sliding grooves 411 can be used for matching with a traditional T-shaped nut bolt.

In this embodiment, the device further comprises a connecting piece 6, a sliding mechanism 42 is arranged at the upper end of the material supporting frame 4, the sliding mechanism 42 comprises a mounting seat 421 and a plurality of rollers 422, the mounting seat 421 is fixedly mounted with a sliding groove 411 at the upper end of a supporting rod 41 of the material supporting frame 4 in the vertical direction through a T-shaped nut, and the mounting seat 421 and the sliding groove 411 are mounted in parallel to each other, so that the rollers 422 can roll in the same direction when stressed; the mounting seat 421 has a receiving cavity for mounting the roller 422, and a plurality of rollers 422 can be mounted in the receiving cavity for rolling; wherein, connecting piece 6 is "right-angle shape" structure, and guide 5 accessible connecting pieces 6 fixed mounting are on the sliding tray 411 of bracing piece 41 side, and the one end of connecting piece 6 sets firmly on guide 5, and the other end sets firmly on sliding tray 411, and encloses into bracing piece 41 of hollow rectangular structure and also through connecting piece 6 mutual fixed mounting.

In this embodiment, there are two material holders 4, one of which is disposed on the feeding side of the lower mold 2, and the installation distance is adjusted according to the position of the feeding side of the lower mold 2, when the material holders are completely disposed on the feeding side, the guide block 5 is fixed on the support rod 41 through the connecting piece 6; the other one is arranged at the discharge side of the lower die 2, the installation distance is adjusted according to the position of the feed side of the lower die 2, and when the other one is completely positioned at the discharge side, the guide block 5 is fixedly arranged on the support rod 41 through the connecting piece 6; meanwhile, as the spring 32 is not stressed, when the plate enters the material supporting frame 4 at the feeding side, the material supporting frame 4 automatically supports the balance of the plate so as to ensure that the plate is accurately positioned and stably transmitted on the die; after the material supporting frame 4 is matched with the die to complete stamping, the sheet material stably slides out of the die from the sheet material on the discharging side.

Utility model's theory of operation and use flow: when the device is used, a plate enters the material support frame 4 on the feeding side through the material rolling machine to be positioned; when the upper die 1 moves downwards relative to the lower die 2, the guide part 10 of the upper die 1 abuts against the guide block 5, the guide block 5 drives the ejector sleeve 31 to move downwards on the spring 32, and the blanking frame moves to the pushing position, so that the stamping can be finished; then, the upper die 1 moves upward relative to the lower die 2, the spring 32 is in an extended state, the spring 32 drives the ejector sleeve 31 to slide upward, and the material supporting frame 4 moves to an initial position to be balanced and fixed. Therefore, the technical proposal of the utility model has simple structure and convenient assembly; need not through the cylinder, only need can guarantee through elasticity resetting means 3 and hold in the palm work or material rest 4 all the time when on the mould and keep balance effect, more be favorable to manufacturing, improve production efficiency.

The description of the above specification and examples is intended to illustrate the scope of the invention, but should not be construed as limiting the scope of the invention. Modifications, equivalents and other improvements which may be made to the embodiments of the invention or to some of the technical features thereof by a person of ordinary skill in the art through logical analysis, reasoning or limited experimentation in light of the above teachings of the invention or the above embodiments are intended to be included within the scope of the invention.
