Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of aluminium alloy surface treatment, in particular to a low color difference value high uniform film thickness electrophoresis aluminium profile product production's frock hanger. BACKGROUND

[0002] Aluminium alloy anodic oxidation surface treatment is to put aluminium profile into acid electrolyte solution and pass high-voltage direct current to form porous structure oxide film on the surface of the aluminium profile. The oxide film has the advantages of high hardness and strong corrosion resistance. In conventional operation, one end or both ends of the aluminium profile are tied to the hanger by iron wire, or a plurality of hanging points are provided on the hanger, the hanging points are inserted into the processing holes on the aluminium profile, and then the aluminium profile is immersed into the liquid tank of the oxidation process in sequence.

[0003] However, the hanger has the following disadvantages: the profile must have processing holes as a prerequisite, and the profile without processing holes cannot be fixed. The hanger tied by iron wire has the following disadvantages: the profile will have traces of iron wire marks, which will affect the overall effect of the aluminium profile; the iron wire tying relies on the skill and technology of the tying operator, and if the tying is not stable, it will cause the aluminium profile to fall off; the tying process is laborious and time-consuming, which will affect the production efficiency. In addition, the iron wire tying part will have different color from the profile after electrophoretic oxidation due to insufficient oxidation degree, and there will be obvious color difference traces. The film thickness detector will also find that the local film thickness is significantly different from the normal part, which will cause the film thickness uniformity to be out of tolerance. SUMMARY

[0004] The utility model aims at providing a low color difference value high uniform film thickness electrophoresis aluminium profile product production's frock hanger, adopt clamping type's fixed mode, with oxidation hanger fixed aluminium profile, fixed mode is simple and easy to implement, fast and stable, aluminium profile is not easy to fall off on the hanger.

[0005] To achieve the above-mentioned purpose, the technical scheme of the utility model is as follows:

[0006] A low color difference value high uniform film thickness electrophoresis aluminium profile product production's frock hanger, a plurality of clamps are fixed on the hanger beam, the upper end of the clamp base plate of the clamp is fixed with the hanger beam, two side plates are vertically fixed in the middle of the clamp base plate, a lower part between the two side plates is hinged to a ratchet cam, the side close to the clamp base plate of the ratchet cam is protruding and provided with a ratchet, the aluminium profile is clamped and fixed between the ratchet cam and the clamp base plate, and the ratchet cam is driven to rotate by a driving mechanism.

[0007] The ratchet slightly bites into the surface of the profile under the pressure of the cam, and due to the anti-slip effect of the one-way ratchet, the aluminium profile almost cannot come out of the clamp without material damage; the driving mechanism for driving the ratchet cam can be a wrench, a bolt, a handle, a torsion wheel or other mechanisms.

[0008] The lower part between the side plates is also hinged with the lower end of the gear wrench, and the gear wrench is provided with gear teeth to engage with the gear teeth on the ratchet cam.

[0009] The above lists a structure of driving the ratchet cam, which utilizes the gear teeth of the gear wrench to engage with the gear teeth on the ratchet cam, and the gear wrench can be pulled to drive the ratchet cam to rotate through the hinge; when the gear wrench is pulled, the ratchet part of the ratchet cam rotates downward to be separated from the aluminum profile, so that the unloading is realized. When the gear wrench is returned to the original position, the ratchet part of the ratchet cam rotates upward to press the aluminum profile, so that the aluminum profile is clamped.

[0010] The middle part of the gear wrench is connected with the clamp base plate through a tension spring.

[0011] The tension spring can provide a restoring force for the gear wrench, and the gear wrench is in a state of clamping the aluminum profile as a normal state without external force.

[0012] The gear wrench is in a bent shape. The bent wrench can facilitate the operator to apply force.

[0013] Advantages of the utility model

[0014] 1. The utility model adopts a clamping type fixing mode to fix the aluminum profile and the oxidation hanger, and the fixing mode is simple, easy to operate, fast and stable, and the aluminum profile is not easy to be loosened on the hanger.

[0015] 2. The utility model utilizes the local profile surface pressing of the ratchet teeth to press the profile surface, and the profile is completely immersed in the oxidation tank liquid, so that obvious marks, color difference and local film thickness excess are not left, and the oxidation effect on the profile surface is not adversely affected.

[0016] 3. The utility model has a simple structure, is easy to manufacture and maintain, and is easy for the operator to operate. DETAILED DESCRIPTION
