Overview of Reverse Hammers for Spotter
Content
The device is intended for use in car services and workshops with Blue Weld welding machines of the Digital plus 5500 and Telwin digital car spotter 5500 models. You can buy a reverse hammer for the spotter separately or together with the specified equipment.
The reverse action hammer is used in car repair to pull out dents on the car body and as a puller when dismantling parts of the chassis. The device can be used to eliminate defects of any thin metal surfaces. The tool is an accessory for a spotter (single-sided spot welding).
Application, construction and principle of operation
Restoration of the geometry of body elements using this tool is carried out when it is impossible to access the repaired surface from inside the car. Most often, this situation occurs when the racks and thresholds are damaged. The use of a reverse hammer when straightening body parts with a large area (roof, hood) is inefficient and risky.
The basis of the fixture is a rod made of a rod or a thick-walled tube, which serves as a guide for a massive striker-sleeve. The pin passes through a hole in the weight and is attached to the dent with the help of nozzles in the form of a vacuum suction cup, hook-grab, cup or electrode. The opposite end of the rod is held by the handle, which is protected from the impact of the striker by an emphasis (guard).
The basis of the device is a bar rod
The electrode is installed inside the tube and connected to the welding machine through an adapter. The grips cling to special washers or brackets welded to the repair site. When using a suction cup, it is not necessary to remove the paintwork and in some cases it is possible to bring the part to the factory state without painting.
The reverse hammer is actuated by a sharp supply of a load from the nozzle to the handle. This is done with a free hand on a mechanical device or air pressure - on a pneumatic one. The design is not easy to make on your own - it's easier to buy a reverse hammer for the spotter. In the kit with the finished product, different tips can be sold, making the device universal.
