Description

Technical Field

[0001] The utility model relates to the technical field of aluminum processing hot rolling, in particular to a tool for detecting the surface of an aluminum processing hot rolled coil. Background Art

[0002] When the hot rolled coil surface is gently wiped with soft materials, some black stains will be left, which is aluminum powder. Aluminum powder is produced by the friction and wear of the rollers on the surface of the rolled product in the deformation zone. The main components are Al2O3, Al powder and a small amount of oily mixture. In serious cases, it affects the control of surface quality in the downstream cold rolling process.

[0003] The amount of aluminum powder attached to the surface of the hot-rolled coil of 5182 can cover material will affect the performance of black silk and black lines in the downstream production process of the coil. Black silk and black lines are one of the most fatal defects of can cover materials. Severe black silk and black lines will cause can leakage. Therefore, it is necessary to quantitatively detect the amount of aluminum powder attached to the surface of the hot-rolled coil. At present, the detection method adopted by our company is to fix cotton cloth under the iron block, and then use the weight of the iron block to wipe back and forth on the surface of the strip. After wiping, the part of the cotton cloth with aluminum powder forms an aluminum powder belt. The aluminum powder belt part is scanned to generate a picture, and then subsequent detection is carried out. The defects of this method are: the worker manually moves the iron block to wipe on the strip, and the wiping force and wiping range cannot be accurately controlled, which reduces the detection effect and is inconvenient to use.

It is easy to use and can effectively solve the problems in the background technology.

[0006] As a preferred technical solution of the utility model, a groove is provided on the peripheral side surface of the counterweight block, and the elastic band is movably sleeved inside the groove.

[0007] As a preferred technical solution of the utility model, the driving member includes a mounting seat, a slide rail is installed on the mounting seat, and a linear motor is slidably arranged on the slide rail for driving the counterweight block to move back and forth.

[0008] As a preferred technical solution of the utility model, a longitudinally arranged cylinder is installed on the side of the linear motor, a top plate is provided at the telescopic end of the cylinder, and a telescopic rod connected to the counterweight block is provided on the top plate.

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] See also Figure 1 The utility model provides a technical solution: a tool for detecting the surface of hot-rolled coils in aluminum processing, comprising a counterweight 1, the bottom of the counterweight 1 is wrapped with cotton cloth 2, the peripheral side of the counterweight 1 is movably sleeved with an elastic belt 4 for fixing the cotton cloth 2, and the top of the counterweight 1 is provided with a driving member for driving the counterweight 1 to move back and forth. The tool is located on the upper side of the strip to be detected, and the cotton cloth 2 is put on from the lower side of the counterweight 1 and fixed by the elastic belt 4. The driving member drives the counterweight 1 to move, and the counterweight 1 drives the cotton cloth 2 to move back and forth on the strip, so that the cotton cloth 2 wipes the surface of the strip;

[0015] The cotton cloth 2 is removed. Aluminum powder is adhered to the corresponding parts of the cotton cloth 2 and the bottom of the counterweight 1. Then, the parts of the cotton cloth with aluminum powder are scanned and tested subsequently.

A telescopic rod 51 connected to the counterweight 1 is provided on the top plate 5. The solenoid valve of the cylinder 52 is opened by controlling the external switch, and the cylinder 52 is extended to move the top plate 5 downward, and the top plate 5 drives the telescopic rod 51 and the counterweight 1 downward until the cotton cloth 2 at the bottom of the counterweight 1 contacts the strip, and the telescopic rod 51 is shortened a certain distance. At this time, the cotton cloth 2 contacts and squeezes the strip under the action of the counterweight 1, ensuring that the force applied to the cotton cloth 2 is fixed.
