Description

Technical Field

[0001] This utility model belongs to the field of blanking die technology, and in particular relates to an aluminum profile trimming die. Background Technology

[0002] Blanking dies are indispensable process equipment in stamping production, and a good die structure is a reliable guarantee for realizing the process plan. The quality and precision of stamped parts mainly depend on the quality and precision of the blanking die. Whether the blanking die structure is reasonable and advanced directly affects production efficiency, the service life of the blanking die itself, and the safety and convenience of operation. Due to the differences in the shape, size, precision, production batch, and production conditions of the blanked parts, the structural types of blanking dies also vary.

[0003] However, in actual production, the diverse designs of parts lead to increasingly complex manufacturing processes, such as... Figure 9 The aluminum profile shown requires cutting a piece (red area) from inside a conventional aluminum profile. Since the cutting location is inside the aluminum profile, and the aluminum profile is a hollow square tube, the traditional punching die structure cannot be used. Manual cutting would be very costly in terms of labor and time. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] An aluminum profile trimming mold includes a mold body consisting of an upper mold and a lower mold, wherein the lower mold includes a lower mold base plate and a trimming structure mounted on the lower mold base plate for trimming aluminum profiles;

[0006] The trimming structure includes at least one set of trimming components for trimming aluminum profiles and at least one set of ejection components for ejecting waste material. It also includes a lock cylinder assembly for fixing / releasing the trimming components. When the lock cylinder assembly fixes the trimming components, the trimming components can trim the aluminum profiles. When the lock cylinder assembly releases the trimming components, the aluminum profiles can detach from the trimming components.

[0007] Furthermore, the trimming structure also includes a limiting component, which is used to limit the displacement of the aluminum profile. The limiting component includes at least two sets of fixing blocks installed on the lower mold base plate. The two sets of fixing blocks are respectively located on both sides of the aluminum profile. One set of fixing blocks is also equipped with a limiting block. The limiting block is connected to the fixing block by a number of equal-height screws. The equal-height screws are also fitted with elastic elements.

[0008] Furthermore, the trimming assembly includes a lower cutting edge plate mounted on the lower die base plate and an upper cutting edge plate slidably connected to the lower cutting edge plate. The sliding connection is also provided with a springback limiting mechanism. The upper cutting edge plate is provided with an upper cutting edge, and the lower cutting edge plate is provided with a lower cutting edge that matches the upper cutting edge. When the upper cutting edge plate moves up / down, the upper cutting edge and the lower cutting edge shear the aluminum profile.

[0009] Furthermore, the stripping assembly includes a first driving element mounted on the lower die plate and a push rod disposed at the output end of the first driving element. The lower cutting edge is provided with a through hole for accommodating the push rod. The first driving element can push out the waste material sheared in the lower cutting edge. The lower die plate is provided with a waste outlet, and the waste material falls into the waste outlet after being pushed out.

[0010] Furthermore, the lock cylinder assembly includes a second driving element mounted on the lower mold base plate and a sliding plate disposed at the output end of the second driving element. A locking block is fixedly connected to the sliding plate. The locking block is located on the side of the lower blade plate away from the lower cutting edge. The second driving element can drive the locking block to disengage from / lock the lower blade plate.

[0011] Furthermore, the stripping assembly also includes a guide block fixed on the lower die plate, the guide block being slidably connected to the push rod, and the guide block being used to guide the push rod.

[0012] Furthermore, the lock cylinder assembly also includes at least two sets of sliders, which are used to guide the sliding plate to slide left / right.

[0013] The beneficial effects of this utility model are:

[0014] This utility model lock cylinder assembly first releases the trimming component, then inserts the aluminum profile, the limiting component can self-position the aluminum profile, the upper mold presses down on the trimming component, the upper and lower cutting edges of the trimming component cut off the waste material, the stripping component pushes the waste material out and it falls into the waste material groove, and then the trimming component is released to remove the aluminum profile to complete the processing. This utility model is simple and convenient to process, can quickly complete the internal waste material cutting processing of aluminum profiles, speed up the production cycle and reduce labor costs.
