QCJ-120漆膜冲击器工作原理：

由控制器螺钉将带有挂钩的重锤固定在所要求的高度上，其高度即滑筒刻度所示高度刻线与定位标刻线重合。按压控制螺钉则控制器弹簧被压缩，此时控制滑块的圆孔与控制器上盖及控制器下底的圆孔对正使挂钩脱落，重锤落下，撞击冲杆，冲杆向下作用在事先放在枕垫块上的试板上。之后，提升重锤体，取出试板，以观察试板上漆膜试验情况。

QCJ-120 paint film impactor working principle

The weight of the hammer with the hook is fixed to the required height by the controller screw, and its height, that is, the height engraved line indicated by the cylinder scale coincides with the positioning engraved line. When the control screw is pressed, the controller spring is compressed. At this time, the round hole of the control slider is aligned with the round hole of the upper cover of the controller and the bottom of the controller to make the hook fall off. On a test panel that has been placed on a pillow block in advance. After that, lift the weight body and take out the test plate to observe the paint film test on the test plate.

QCJ-120漆膜冲击器操作与使用：

准备，使用前，请详细阅读本说明书。

调零。检查定位标是否对零线，如有偏差，将重锤降落到滑筒底部（因冲杆部分装有复位弹簧，重锤需沿滑道向下按压，才能降到底部）。调节定位标两侧螺钉。使定位标上刻线与零线重合。

底座留有二个安装孔，可用M12螺栓将冲击器稳装在平坦的地面或工作台上。

QCJ-120 paint film impactor operation and use

Read and read this manual before use.

Zero. Check whether the positioning mark is aligned with the zero line. If there is a deviation, lower the weight to the bottom of the slide tube (because the reset spring is installed in the punch rod, the weight must be pressed down the slide rail to lower to the bottom). Adjust the screws on both sides of the positioning mark. Make the mark on the positioning mark coincide with the zero line.

The base has two mounting holes, and the impactor can be stably mounted on a flat floor or a worktable with M12 bolts.

QCJ-120漆膜冲击器操作：

试板的放置。把备妥的试板放置在枕垫块上，且紧贴于枕垫块凹孔，漆膜朝上，使受冲击点距试板边缘不少于15mm，或在试板中间处。若使用一个试板作数次试验时，应使每个冲击点边缘相距不少于15mm。

重锤投放高度的设置。同时松动控制器螺钉，控制器件可按滑筒两侧滑道上下移动。根据试验要求，先取高度时，请将定位标上刻线与滑筒刻度线重合即可，将控制器螺钉拧紧、固定。

试验举例。依照标准中的有关规定，完成重锤投放高度的设置，将制备好的试板置于枕垫块上。按压控制螺钉，重锤即自由地落在冲杆上，冲杆将冲击力传给枕垫块上的试板。将重锤提升起，由控制器挂住重锤上的挂钩，取出试板。用4倍放大镜观察，判断漆膜有无裂纹、皱纹及剥落等现象。本试验举例仅供参考，具体的试验方法，以标准中的有关规定为准。

QCJ-120 paint film impactor operation

Placement of test plates. Place the prepared test plate on the pillow block and close to the recessed hole of the pillow block with the paint film facing up so that the impact point is not less than 15mm from the edge of the test plate, or in the middle of the test plate. If a test plate is used for several tests, the distance between the edges of each impact point shall be not less than 15mm.

Setting of the weight drop height. At the same time loosen the controller screw, the control device can move up and down according to the slide rails on both sides of the slide. According to the test requirements, when taking the height first, you can overlap the engraved line on the positioning mark with the scale line of the sliding cylinder, and then tighten and fix the controller screws.

Test example. According to the relevant provisions in the standard, complete the setting of the height of the weight hammer, and place the prepared test plate on the pillow block. When the control screw is pressed, the weight is freely dropped on the punch, and the punch transmits the impact force to the test plate on the pillow block. Raise the weight, hold the hook on the weight by the controller, and remove the test plate. Observe with a 4x magnifying glass to determine whether the paint film has cracks, wrinkles and peeling. This test example is for reference only. The specific test method is subject to the relevant provisions in the standard.

QCJ-120漆膜冲击器维护与保养：

仪器应置于干燥、清洁、无腐蚀性气体环境中。仪器应经常保持清洁，运动部分灵活。

当控制器因保管或使用不当有障碍时，可用内六角扳手松开支臂上M10内六角螺钉，将滑筒卸下，然后拧下控制器螺钉，重锤及两侧螺钉，由管底部用改锥卸下定位标支架紧固螺钉，即可将控制器取出进行清洁、修理。

QCJ-120 Paint Film Impactor Maintenance

The instrument should be placed in a dry, clean, non-corrosive gas environment. The instrument should always be kept clean and the moving parts flexible.

When the controller has obstacles due to improper storage or use, you can use an Allen wrench to loosen the M10 Allen screws on the arm, remove the slide tube, and then remove the controller screws, weights and screws on both sides. Use a screwdriver at the bottom of the tube Remove the positioning bracket fixing screws to take out the controller for cleaning and repair.
