The workbench consists of a base and a pressure plate. The base is connected to the clamping plate through a hinge. The base consists of a base shell, a coil and a cover plate. The coil is placed in the depression of the base shell, and the top of the depression is covered with a cover plate. When in use, the coil is energized by a wire, and after energization, an attractive force is generated on the pressure plate, thereby clamping the thin plate between the pressure plate and the base. Due to the use of electromagnetic force clamping, the pressure plate can be made into a variety of workpiece requirements, and can process workpieces with side walls, and the operation is also very simple.

[0003] During the use of the existing bending machine, when the upper mold knife needs to be replaced, the multiple positioning clamp assemblies fixed to the upper mold knife need to be separated, that is, by loosening the bolts of the two positioning clamps on each set of positioning assemblies.

[0012] Beneficial Effects

[0013] The utility model provides a plate bending device for machining a machine tool shell, which has the following beneficial effects:

[0014] (1) A plate bending device for processing a machine tool shell. During use, when the upper mold knife needs to be removed, the transmission worm can be rotated forward, and the transmission worm drives multiple transmission worm wheels to rotate forward, multiple connecting sleeves start to rotate forward, and multiple distance adjustment connecting rods rotate forward synchronously.

[0015] (2) A plate bending device for processing a machine tool shell. During use, when the distance adjusting rod is in motion, the transmission connecting block moves inside the limiting connecting slot, which can improve the stability of the distance adjusting rod during movement. The tool is inserted into the interior of the transmission worm, which facilitates the rotation of the auxiliary slot. Since the limiting connecting block and the limiting slot are plug-in connected, the stability after positioning can be increased. In addition, when the positioning clamp moves, the limiting connecting block moves inside the limiting slot, and the sliding ball reduces the resistance between the limiting connecting block and the limiting slot, which makes operation more labor-saving.
