Description

Technical Field

[0001] The utility model relates to the technical field of coating impact resistance detection, in particular to a thermal spray coating impact resistance toughness detection device. Background Art

[0002] The coating impact toughness test device is completed by allowing a certain mass to fall freely, and then records the maximum impact height that the film can withstand without damage. It complies with GB / T 1732-93 "Test method for impact resistance of paint films". The specific operation steps are as follows: Place the test plate film side up flat on the iron table of the impact tester. Use the control device to fix the weight at a certain height to control the impact energy. Press the control button, and the weight will fall freely onto the punch, affecting the coating template. Remove the test plate and record the maximum height of the film after the weight falls. Inspect the test plate for cracks, wrinkles or peeling.

[0003] After searching, the existing patent (Announcement No.: CN 213749440 U) discloses a device for detecting the impact toughness of thermal spray coatings. The device is composed of a lifting assembly and a continuous steel ball throwing assembly. The lifting assembly includes a base, a servo motor, a ball screw pair, and a vertical plate. The servo motor is mounted on the base. The ball screw pair is connected to the servo motor. The ball screw pair is rotatably connected to a ball screw nut pair. The ball screw nut pair is connected to a slide rod. A slide rail compatible with the slide rod is provided on the vertical plate. The continuous steel ball throwing assembly includes a mounting cover, a ball launching part, a ball lowering pipe, a ball distributing part, and a ball storage part. In the utility model, the continuous steel ball throwing assembly does not require manual placement of a new steel ball for continued testing after each steel ball is thrown. It can automatically receive and launch the ball after each change in the height position of the ball launching part.

[0004] However, there are still some deficiencies in the above scheme. After the device uses a small ball to detect the thermal spray coating, the small ball is dropped from the same height each time, and the impact detection effect at different heights cannot be demonstrated. In addition, when detecting the opposite impact position, the detection coating needs to be reversed before the detection can be carried out.

[0005] In view of this, the utility model proposes a device for detecting the impact toughness of a thermal spray coating. Utility Model Content
