Description

Technical Field

[0001] The utility model relates to the technical field of workpiece punching dies, in particular to a workpiece punching die tooling. Background Art

[0002] Die tools are usually used to punch materials out of strips or coils. This process is usually called stamping or blanking. In this case, the die tool will cut or punch the material of the required shape out of the strip or coil under the action of pressure or impact.

[0003] In the prior art, after the punch tooling punches the material down, the material will fall on the lower die, and workers are required to move the material out from the top of the lower die. This will not only delay the stamping work of the material strip, but also there will be certain safety risks when the worker's hand reaches into the top of the lower die, that is, directly below the lower die. Summary of the invention

[0004] The utility model aims to solve the problem in the prior art that after the material is punched down by the punching die tooling, the material will fall on the lower die, and the worker is required to move the material out from the top of the lower die, which will not only delay the material stamping work on the material strip, but also there will be certain safety risks when the worker's hand extends into the top of the lower die, that is, directly below the lower die, and a punching die tooling for a workpiece is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A die tooling for a workpiece comprises a receiving platform, a vertical plate is vertically fixedly arranged on the top of the receiving platform, a top receiving platform is horizontally fixedly arranged on the top of the vertical plate, a die cylinder is vertically fixedly arranged on the top of the top receiving platform, a movable die is fixedly arranged on the output end of the die cylinder, a fixed die is fixedly arranged on the receiving platform just below the movable die, a horizontal rod is fixedly arranged on the side edge position of the fixed die, a vertical rod is fixedly arranged on the top of the end of the horizontal rod, and a material stripping component for assisting the movable die in automatically stripping material is arranged on the top of the vertical rod.

[0007] Optionally, a vacuum tube is symmetrically fixedly arranged on the top of the movable mold, and the top of the vacuum tube is movably inserted into the top connection platform.

[0008] Optionally, the material return assembly includes a material receiving plate, a common rod, and an inclined rod, and the common rod is obliquely fixedly provided on the top side of the vertical rod.

[0009] Optionally, both ends of the common rod are rotatably connected to tilting rods, and the bottom of the tilting rod is rotatably connected to the side of the material receiving plate.

[0010] Optionally, a clearance groove is provided at the top edge of the movable mold, the interior of the clearance groove is rotatably connected to one end of a driving rod, and the other end of the driving rod is rotatably connected to the top of the side of the tilting rod.

[0011] Optionally, one end of the top of the material receiving plate extends below the movable mold, and a material blocking edge is fixedly provided at the edge of the top surface of the material receiving plate.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] 1. The utility model is provided with an automatic material return assembly on the side of the fixed die through a vertical rod. When the movable die completes the punching and shearing action of the material, the material will be adsorbed to a certain position through a vacuum tube during the return stroke and then cooperate with the automatic material return assembly to release the material to the top of the material return assembly. This not only greatly reduces the downtime of the die tooling, but also eliminates the need for workers to extend their hands under the movable die, which can completely avoid safety accidents of the machine crushing the hands.

[0014] 2. The utility model is provided with an automatic material ejection assembly on the side of the fixed die through a vertical rod. When the movable die approaches the fixed die, the driving rod will force the automatic material ejection assembly to move out of the path of the movable die downward, so as to avoid affecting the normal operation of the entire die tooling.

Implementation

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-3 A die tooling for a workpiece includes a receiving platform 21, a vertical plate 2 is vertically fixed on the top of the receiving platform 21, a top receiving platform 1 is horizontally fixed on the top of the vertical plate 2, a die cylinder 3 is vertically fixed on the top of the top receiving platform 1, the output end of the die cylinder 3 faces vertically downward, a movable die 4 is fixed on the output end of the die cylinder 3, and a fixed die 5 is fixedly provided on the receiving platform 21 directly below the movable die 4.

[0022] A horizontal rod 13 is fixedly set at the side edge of the fixed mold 5, a vertical rod 12 is fixedly set at the top of the end of the horizontal rod 13, a material return assembly for assisting the movable mold 4 to automatically return the material is set on the top of the vertical rod 12, and a vacuum tube 41 is symmetrically fixed on the top of the movable mold 4. The top of the vacuum tube 41 is movably inserted into the top connection platform 1, and the bottom of the vacuum tube 41 is flush with the bottom of the movable mold 4.

[0023] The material return assembly includes a material receiving plate 11, a common rod 9, and an inclined rod 8. The common rod 9 is fixedly and obliquely arranged on the top side of the vertical rod 12. The two ends of the common rod 9 are rotatably connected to the inclined rod 8. The bottom of the inclined rod 8 is rotatably connected to the side of the material receiving plate 11. There are two groups of inclined rods 8 in total.

[0024] A clearance groove 6 is provided at the top edge of the movable mold 4, and the inside of the clearance groove 6 is rotatably connected to one end of the driving rod 7. The other end of the driving rod 7 is rotatably connected to the top of the side of the inclined rod 8. One end of the top of the material receiving plate 11 extends under the movable mold 4, and a material blocking edge 10 is fixedly provided at the edge of the top surface of the material receiving plate 11.

[0025] It should be supplemented that the top of the vacuum tube 41 is externally connected to a vacuum generator, and the vacuum generator is connected to an air pump.

[0026] The specific implementation steps and principles of the utility model are as follows:

[0027] The workers continuously feed the material belt to the top of the fixed mold 5. At this time, when the movable mold 4 is close to the fixed mold 5, the driving rod 7 will push the tilting rod 8 to rotate around one end of the common rod 9. Since the common rod 9, two sets of tilting rods 8 and the receiving plate 11 form a parallelogram structure, the receiving plate 11 will move downward obliquely. After the movable mold 4 completes the punching work, the material will be adsorbed to a certain height through the vacuum tube 41. At this time, the receiving plate 11 moves upward obliquely under the action of the same components mentioned above and extends to the bottom of the movable mold 4. At this time, the vacuum generator is turned off and the material falls onto the receiving plate 11.

[0028] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
