Description

Technical Field

[0001] The invention relates to the field of aluminum alloy processing, in particular to an aluminum alloy precision stamping and forging device based on bicycle frame processing. Background Art

[0002] The bicycle frame is the skeleton and main body of the bicycle. Other parts are also directly or indirectly installed on the frame. As the core part of the entire bicycle, the bicycle frame determines the correctness and comfort of the riding posture to the greatest extent. It is the basic structure of the bicycle.

[0003] The chain guard of a bicycle frame needs to be processed by stamping. Aluminum alloy is usually used as the raw material. The aluminum alloy plate is placed on a raised mold and is formed by stamping. The existing Chinese public patent document: CN112091037A discloses an aluminum alloy profile stamping device. During stamping, the symmetrically arranged protective plates move towards each other and close together. During the upward movement of the lifting plate, the symmetrically arranged protective plates move back to back and separate. Although it can provide protection for the user during stamping, when taking the material, since the formed protective shell will be covered on the mold, the user needs to use a clamp to pick up the protective shell. Under the cover of the two protective plates, it is difficult to observe the position and clamping of the clamp. If the staff uses too much force, it is easy to cause the outer side of the protective shell to become concave, thereby reducing the production quality of the protective shell.

At this time, the ..., so that the U-shaped plate 15 drives the moving box 12 to move along the inner side of the equipment base 1, and the moving box 12 drives the moving box 13 to move upward, so that the moving box 13 drives the lower mold 6 to move above the moving frame 5. The upper mold 4 can punch the aluminum alloy plate on the lower mold 6 to form an aluminum alloy protective shell for the bicycle chain. Then, the user starts the hydraulic rod 3 again, so that the hydraulic rod 3 drives the upper mold 4 to move upward, and the upper mold 4 moves away from the lower mold 6 and continues to move upward, so that the upper mold 4 drives the rack 2 19 on the L-shaped rod 18 to contact the gear cylinder 17 again. As the upper mold 4 moves, the rack 2 19 drives the gear cylinder 17 to rotate, and the gear cylinder 17 drives the U-shaped plate 15 to move along the sliding cavity on the equipment base 1 through the rack 1 16, so that the U-shaped plate 15 drives the moving box 12 to reset along the inner side of the equipment base 1, so that the lower mold 6 in the moving frame 5 is misaligned with the upper mold 4. At the same time, The moving box 12 drives the mounting rod 14 along the guide groove 1 on the equipment base 1 back to the guide groove 2, so that the mounting rod 14 moves downward along the inclined surface of the guide groove 2, and the mounting rod 14 pulls the sliding box 13 along the vertical groove on the moving box 12 to move along the inner side of the moving box 12. The sliding box 13 pulls the lower mold 6 along the inner side of the moving frame 5 through the clamping plate 27 to move downward along the inner side of the moving frame 5, so that the skirt of the aluminum alloy protective shell on the lower mold 6 contacts the four anti-pillars 23, and the aluminum alloy protective shell is pushed out from the lower mold 6. Finally, the user takes out the manufactured aluminum alloy protective shell and places another aluminum alloy plate on the lower mold 6, and then stamping can be performed again, thereby achieving the effect of safe loading and unloading.
