Description

Technical Field

[0001] This utility model relates to the field of die forging processing technology, and more specifically, it relates to a die forging trimming device. Background Technology

[0002] Die forging is a common metal processing method. Through precise die design and control, it can process metal products with complex shapes, ensuring product precision and making the internal structure of the metal material more compact, thus improving the mechanical properties and wear resistance of the metal material. It can also be mass-produced, with high production capacity and short cycle time. In the production of aluminum containers, excess molten aluminum inside the forging die cavity can easily form metal flash. Flash plays a role in ensuring that the molten aluminum fills the die cavity. However, in order to ensure the normal processing and use of the aluminum container, the flash must be removed after die forging. This is where the flash trimming device is needed.

[0003] When the existing edge-cutting device is in use, the aluminum scrap it cuts off is easy to stick to the bottom of the edge-cutting device because of its good ductility. This can easily cause workers' fingers to be cut when manually picking up the scrap, resulting in poor safety.

[0004] Furthermore, after the aluminum container is trimmed, the bottom of the container tends to stick to the die, making it difficult to remove the trimmed container and thus affecting the material handling speed of the forging. Utility Model Content

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a cutting device for forgings, which has the following advantages:

[0018] 1. By setting up a top block, connecting rod, and pressing block, the user can place the aluminum container to be processed into the die cavity. Then, the user controls the cylinder to move the lifting plate downwards, so that the cutting blade at the bottom of the die can cut off the excess metal edge on the aluminum container, thereby achieving the edge trimming effect. When the cut-off flash sticks to the bottom of the die, the user can press the pressing block to move the connecting rod downwards, thereby removing the flash from the bottom of the die and facilitating subsequent material removal. This design not only increases the speed of scrap material removal but also avoids the dangerous situation that can easily occur with manual material removal, thus helping to increase the edge trimming efficiency.

[0019] 2. By setting up a sliding rod, a lifting plate, and a handle, the user can push the handle upwards to move the sliding rod and the lifting plate upwards, thereby pushing the aluminum container out of the groove. This facilitates the quick retrieval of the aluminum container after it has been trimmed, making it convenient to use.

[0020] 3. By setting up a shell, a waste bin, and a slider, users can remove the waste bin from inside the shell through the cooperation of the slider and the chute, so as to put the cut waste into the waste bin. This facilitates the centralized collection and recycling of waste in the later stage. This design not only reduces the waste of some resources, but also ensures the cleanliness of the top of the base and increases practicality. Attached Figure Description

A cutting blade 7 is mounted on the outer side of the punch 6 and on the lower surface of the lifting plate 5. A corresponding cutting groove 8 is formed on the upper surface of the base 1. Grooves 9 are formed on both sides of the lower surface of the lifting plate 5 and on both sides of the cutting blade 7. Each part is provided with a top block 10, and each top block 10 is fixedly provided with a connecting rod 11 on its upper end surface. The upper end of each connecting rod 11 passes through the lifting plate 5 and is provided with a pressing block 12. Each pressing block 12 is provided with a first spring 13 on its lower end surface. The other end of each first spring 13 is fixedly installed with the upper end surface of the lifting plate 5. A concave mold 14 is provided in the middle position of the base 1. The bottom of the concave mold 14 and both sides are provided with sliding holes 15. Each upper end surface of the lifting plate 5 and the four corners are provided with guide holes 26. The guide holes 26 are slidably installed with the guide rod 2.

[0032] In this embodiment, a sliding rod 16 is slidably provided inside the sliding hole 15, and a lifting plate 17 is fixedly provided at the upper end of the sliding rod 16. The lifting plate 17 is located inside the cavity mold 14. The lower end of the sliding rod 16 passes through the sliding hole 15 and is fixedly provided with a handle 18. The outer diameter of the handle 18 is larger than the outer diameter of the sliding rod 16. A second spring 19 is fixedly provided at both ends of the handle 18. The second spring 19 is located outside the sliding rod 16, and its upper end is fixedly connected to the lower end face of the cavity mold 14. The outer surface of the lifting plate 17 is in contact with the inner wall of the cavity mold 14, and the two have the same shape.

[0033] More specifically, the user can place the aluminum container to be processed into the concave mold 14, and then control the cylinder 4 to make the lifting plate 5 move the punch 6 downward, so that the cutting blade 7 at the bottom of the punch 6 can cut off the excess metal edge on the aluminum container, thereby achieving the effect of trimming. When the trimmed flash sticks to the bottom of the punch 6, the user can press the pressing block 12 to make the connecting rod 11 move the top block 10 downward, so as to push off the flash at the bottom of the punch 6, making it easier to remove the material later. The user can also push the handle 18 upward to make it move the sliding rod 16 and the lifting plate 17 upward, so as to push the aluminum container inside the groove 9 out, which helps to quickly pick up the trimmed aluminum container later, making it convenient to use.

[0034] Please see Figure 1 and Figure 4 As an implementation method for collecting waste material from the cut edges: a housing 20 is fixedly provided on the lower end face of the base 1, the front end of the housing 20 is open, an external base 21 is fixedly provided on the lower end face of the housing 20, a waste box 22 is movably provided on the upper end of the external base 21, the waste box 22 is located inside the housing 20, sliders 23 are fixedly provided on both sides of the waste box 22, and a corresponding groove 24 is provided on the inner wall of the housing 20, and the sliders 23 and the grooves 24 are slidably installed.

[0035] Specifically, users can use the cooperation of slider 23 and slide 24 to remove the waste bin 22 from the inside of the housing 20, so as to put the waste material cut off into the waste bin 22, which helps to collect and recycle the waste material later.

[0036] Please refer to Figures 2-4 As a further embodiment for connecting the device to the outside world: external holes 25 are provided on the upper end face of the external connector 21 and at the four corners.

[0037] Specifically, the device can be fixedly installed to the outside world through the external connection hole 25.

[0038] In summary, when using the entire equipment: the user first places the aluminum container to be processed into the concave mold 14, then controls the cylinder 4 to move the lifting plate 5 downwards, causing the cutting blade 7 at the bottom of the punch 6 to cut off the excess metal edge on the aluminum container, thus achieving the edge trimming effect. Afterwards, the user controls the cylinder 4 to raise the punch 6. When the cut-off burrs stick to the bottom of the punch 6, the user can press the pressing block 12 to move the connecting rod 11 downwards, causing the top block 10 to be pushed off, thus removing the burrs from the bottom of the punch 6. Next, the scrap bin 22 is removed from the inside of the housing 20 by the cooperation of the slider 23 and the slide 24, so that the scrap material cut off by the edge can be put into the scrap bin 22, which helps to collect and recycle the scrap material later. When taking out the aluminum container inside the groove 9, the handle 18 can be pushed upward to drive the sliding rod 16 and the lifting plate 17 to move upward, so as to push out the aluminum container inside the groove 9, which helps to quickly take out the aluminum container after the edge is cut and increases the edge cutting efficiency.
