Description

Technical Field

[0001] The invention relates to the technical field of stamping dies, and in particular to a stamping die capable of automatically blanking. Background Art

[0002] Molds are various dies and tools used in industrial production to produce desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. Simply put, a mold is a tool used to create a shaped object. This tool is composed of various parts, and different molds are composed of different parts. It primarily achieves the object's shape by changing the physical state of the material being molded. Known as the "mother of industry," it is a tool that, under the action of external forces, forms a blank into a part with a specific shape and size. It is widely used in blanking, die forging, cold heading, extrusion, powder metallurgy pressing, pressure casting, and compression or injection molding of products such as engineering plastics, rubber, and ceramics. Molds have a specific contour or internal cavity shape, and using a contour with a cutting edge allows the blank to be separated (punched) along the contour line.

[0003] A stamping die is a special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) during the cold stamping process. This is called a cold stamping die (commonly known as a cold die). Stamping is a pressure processing method that uses a die mounted on a press at room temperature to apply pressure to the material, causing it to separate or plastically deform, thereby obtaining the desired part.

[0004] Traditional stamping dies unload materials through the unloading hole at the bottom of the die. The conventional method is to manually remove the product at the bottom of the die. If it is not removed in time, waste will accumulate. If a robot is used to remove the material, the space at the bottom of the die is small, and it is very inconvenient for the robot to remove the material.

[0005] Therefore, how to provide a stamping die capable of automatic blanking to solve the problems existing in the prior art is of great significance to its application. Summary of the Invention

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention transfers the stamped products through a swingable movable plate. During use, after the stamping of the upper template is completed, the product falls into the receiving trough at the top of the movable plate through the material discharge trough, and then the upper template moves upward. During the upward movement of the upper template, the upper template drives the transmission gear 1 to rotate counterclockwise through the driving gear rod. The transmission gear 1 drives the top of the hinge rod 1 to rotate counterclockwise 90 degrees through the rotating shaft 1. At this time, the movable plate is driven to swing through the hinge rod 1 and the hinge rod 2, so that the movable plate moves to the same height as the die, thereby realizing product transfer and facilitating material removal.

[0022] 2. The present invention prevents products from popping out when they fall by setting a material receiving trough. When the movable plate swings upward, the hinged rod one and the hinged rod two respectively drive the rotating shaft two and the rotating shaft three to rotate counterclockwise 90 degrees. The rotating shaft two and the rotating shaft three drive the transmission gear two and the transmission gear three to rotate counterclockwise 90 degrees. The transmission gear two slides upward through the lifting gear rod one. At the same time, the transmission gear three drives the lifting gear rod two to slide upward through the transmission gear four. At this time, the lifting plate moves upward in the material receiving trough, so that the product can be pushed out of the material receiving trough, which is convenient for manual or mechanical arms to take out the material.

[0035] See also Figure 1-4 , the present invention provides a technical solution of a stamping die capable of automatic blanking: comprising an upper template 1, a lower template 6 and a movable plate 12;

[0036] The top of the upper template 1 is fixedly connected to the upper mold connecting column 2, the bottom of the upper template 1 is fixedly connected to the punch 15, the middle of the top of the lower template 6 is installed with the die 5, the side of the top of the lower template 6 is installed with the guide column 3, the upper template 1 is slidably connected to the guide column 3, and the bottom of the lower template 6 is provided with a discharge chute 16;

The front and rear sides of the upper template 1 are fixedly connected to a driving gear rod 4, and the transmission gear 8 is meshed with the driving gear rod 4.

[0040] During the upward movement of the upper template 1, the upper template 1 drives the transmission gear 8 to rotate counterclockwise through the driving gear rod 4, and the transmission gear 8 drives the top of the hinge rod 10 to rotate 90 degrees counterclockwise through the rotating shaft 9. At this time, the movable plate 12 is driven to swing through the hinge rod 10 and the hinge rod 2 13, so that the movable plate 12 moves to the same height as the die 5, thereby realizing product transfer and facilitating material removal.

[0041] The two hinged plates 2 11 are rotatably connected with a rotating shaft 2 17, a rotating shaft 4 23 and a rotating shaft 3 24.

The transmission gear 2 18, the transmission gear 4 22 and the transmission gear 3 19 have the same specifications.

[0044] When in use, the workpiece is placed on the top of the die 5, and then the upper template 1 moves downward, the upper template 1 drives the punch 15 downward and punches the workpiece, and the punched product falls to the top of the lifting plate 20 in the receiving trough 14 through the discharge trough 16, and then the upper template 1 starts to move upward. During the upward movement of the upper template 1, the upper template 1 drives the transmission gear 8 to rotate counterclockwise through the driving gear rod 4, and the transmission gear 8 drives the top of the hinge rod 10 to rotate 90 degrees counterclockwise through the rotating shaft 9. At this time, the movable plate 12 is driven to swing through the hinge rod 10 and the hinge rod 2 13, so that the movable plate 12 moves to the same height as the die 5. Degrees, thereby realizing product transfer and facilitating material retrieval, when the movable plate 12 swings upward, the hinged rod 10 and the hinged rod 132 respectively drive the rotating shaft 2 17 and the rotating shaft 3 24 to rotate 90 degrees counterclockwise, and the rotating shaft 2 17 and the rotating shaft 3 24 drive the transmission gear 2 18 and the transmission gear 3 19 to rotate 90 degrees counterclockwise, and the transmission gear 2 18 slides upward through the lifting gear rod 1 21, and at the same time, the transmission gear 3 19 drives the lifting gear rod 2 25 to slide upward through the transmission gear 4 22.
