Custom aluminum parts

In the production process of the aluminum parts, the aluminum profile metal stamp parts occupy an extremely important position in the stamping process of the aluminum parts and are a basic tool to ensure that the product is formed and has the correct shape, size, and precision. In actual production, metal stamping dies processing may have the following effects on the stamping production of aluminum parts:

The impact of seam corners or poor welding.
The aluminum parts adopts the stamping process of planar shunting combined die. This process is relatively more difficult in the production of the profile. The metal goes through the process of shunting and welding, so there is a welding line in the hollow profile. There are two reasons for the gap: one is the shunt hole, the welding chamber is narrow, the metal supply flow is insufficient, the metal does not form enough hydrostatic pressure in the welding chamber, and the product is not welded well and flows out of the die hole, resulting in the welding of the product The gap; is caused by excessive lubrication and poor lubrication caused by poor welding of hollow profiles.

Stripes on the surface of the aluminum parts.
Streaks appear on the outer surface of stamped profiles, which are more obvious after anodizing. This defect is mostly seen in the part with a large wall thickness difference, the welding part of the metal under the shunt bridge, and the back of the inner side with “branches” and threaded holes. Causes: The “branches” inside the profile and the threaded hole parts cause surface stripes due to insufficient or excessive metal supply; the surface stripes of the profile are caused by the welding area under the mold shunt bridge; the problems in the design of the profile section, due to The wall thickness difference is large, and the part of the working belt with a sudden change in length will produce striped color difference after anodizing. Due to the insufficient cooling capacity of the machine, the black spot area after anodization is caused; the texture of the billet itself is not good, which affects the stripes after anodization of stamping chromatic aberration.

The reasons for the concave or convex arcuate surface of the aluminum parts wall.
The reason for the concave arched surface of the aluminum partswall is that the working belt of the aluminum partsmold core is lower than the working belt of the die hole of the lower mold, and the effective length of the mold core working belt is too short. The reason for the convexity of the shell wall of the aluminum profile: the mold has been used for too long, the working belt of the mold core is severely worn, grooves appear, and the friction resistance is increased. The slow metal flow causes the hollow profile wall to protrude.

Unreasonable ways of bending and twisting the aluminum parts.
The unreasonable coordination of the working belt between the mold core and the lower mold hole causes uneven metal flow velocity in various parts of the aluminum parts; the size and position of the split hole of the symmetrical hollow profile mold are asymmetrically processed, and the metal supply flow is unbalanced, causing uneven metal flow velocity; The processing of the split hole is irregular or there are obstacles on the core to hinder the flow of metal. Solution: Grind the core or the outlet of the split hole with an appropriate method, and expand these split holes appropriately if necessary to balance the material supply; remove the obstruction by grinding.

Learn inspection

This technological process includes:

1: After the workpiece is put on the machine, the work should be re-checked according to the drawing and process. Only when the inspection is within the tolerance range can be processed according to the requirements of the program sheet, so that the drawings, processes, and the program sheet are all corresponding.

2: In terms of size, the touch of the workpiece, and the size of the insertion position meet the requirements of the 3D drawing file. For the position of EDM, CNC needs to leave the EDM margin, and the more important assembly positions should be measured by 3D inspection.

3: For some extremely irregular CNC surfaces or positions with high size requirements, some positions that cannot be measured by common measuring tools, three-dimensional measurement is required if necessary.

4: the workpiece must not have rust, bumps, chipping, and burrs. At the same time, there should not be a large amount of residual cutting fluid, cutting oil, and iron filings in the holes on the surface of the workpiece.

5: According to the 3D drawing file, check whether the workpiece has been completely processed without omission, the benchmark is correct. All the positions requiring sharp corners (especially the sealing position) cannot be chamfered or R.And check the size according to the drawing and then check the self-check. stated on the slip.

6: The CNC machined electrode requires no burrs on the surface, the serial number and electrode number are complete, clear, and correct, and there must be no writing other than the electrode number and electrode number.
