Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of stamping automation, in particular to a stamping automation floating block type detection device. Background Art
[0002] There are two ways to fix the material detection sensor in the existing stamping automation mold. One is to use a standard part input detection switch, which is fixed on the lower mold. The input detection switch can detect whether there is material in the mold cavity and can also be used to position the part in the lower mold. This structure requires milling a cavity on the upper mold base or the upper mold insert to avoid the input detection switch. However, for stamping parts with small flange height, when milling the cavity on the upper mold insert, the R angle distance to the flange insert is close, which affects the strength of the upper mold insert. In this case, the part cannot be externally positioned using the input detection switch; the other is to mill a countersink on the mold surface of the lower mold of the mold, and fix the material detection sensor in the countersink. The sensor cannot exceed the mold surface. When the part After the part is put into the lower mold surface, the part profile fits with the lower mold surface, and the distance between the material detection sensor and the part is greater than zero and less than the sensing distance of the material detection sensor, so the part can be detected. This fixing method of the material detection sensor requires that the part cannot be stuck in the lower mold. If the part is stuck in the lower mold, it is necessary to add a ejector pin on the lower mold surface. However, the length of the ejector pin is often greater than the sensing distance of the material detection sensor, causing the part to be lifted up by the ejector pin after being placed in the lower mold surface. The distance between the part profile and the lower mold surface is greater than the sensing distance of the material detection sensor, and the sensor cannot sense the part, which will make the fixing method of the material detection sensor unusable. Therefore, when the part flange height is small and the lower mold is added with an ejector pin, the above installation method of the material detection sensor cannot be used, the material detection sensor cannot be installed on the mold, and the stamping automation mold cannot be used to stamp the parts. Parts can only be produced manually, which results in low production efficiency and increased labor costs. Summary of the invention

When the floating block 5 is lifted by the spring 7, the hanging platform 19 of the floating block 5 contacts the hanging platform avoiding bottom surface 20 of the upper fixed plate 6 to prevent the floating block 5 from popping out of the hole of the upper fixed plate 6; the spring 7 is loaded into the hole below the floating block 5 13, and penetrate through the hole of the lower template 11 and insert into the lower fixed plate 8. After the bottom surface of the spring 7 contacts with the plane 18 of the lower fixed plate 8, the lower fixed plate 8 is fixed to the lower plane of the lower template 11; one end of the material detection sensor 4 is screwed into the threaded hole of the floating block 5, and the nut 3 is screwed on the material detection sensor 4 from the other end of the material detection sensor 4.
