Automatic rivet removal tool

Abstract

The invention discloses an automatic rivet removal tool which comprises a rivet removal base (2). The rivet removal base (2) comprises a punch base (21), a punch (22), a removal head (3) and a clamping sleeve (4), wherein the punch (22) is arranged in the punch base (21), the punch (22) is sleeved with the removal head (3), and the clamping sleeve (4) is connected to the punch base (21) and prevents the removal head (3) from being disengaged from the punch base (21). The ends, stretching out of the punch base (21), of the removal head (3) and punch (22) are provided with a second arc groove (33) and a first arc groove (220) which are matched with the outer surface of a rivet head of a rivet correspondingly. The bending radian of the second arc groove (33) is equal to that of the first arc groove (220). By means of the rivet removal tool, rivets on workpieces can be removed, the removed rivets can be prevented from being attached to the exterior of the removal tool, operators can remove rivets repeatedly and conveniently, and production efficiency of the operators is effectively improved.

Description

technical field [0001] The invention relates to an automatic rivet removal tool. Background technique [0002] At present, the connection of two workpieces is usually connected by rivets, and riveting errors often occur in the process of processing, which requires disassembly of the rivets. However, the existing rivet disassembly methods include electric drill disassembly, manual disassembly The rivets are disassembled or disassembled by impact. The disassembly by electric drill is easy to damage the workpiece, and the iron filings generated by electric drill disassembly are likely to cause physical injury to the operator, while the work efficiency of manual disassembly is lower. It is very low, which is not conducive to quick disassembly, and the work intensity is high. Although the impact disassembly method can be disassembled quickly, the disassembled rivets are easily attached to the punch, which is not conducive to the operator's multiple disassembly operations and affe...

[0002] At present, the connection of two workpieces is usually connected by rivets, and riveting errors often occur in the process of processing, which requires disassembly of the rivets. However, the existing rivet disassembly methods include electric drill disassembly, manual disassembly The rivets are disassembled or disassembled by impact. The disassembly by electric drill is easy to damage the workpiece, and the iron filings generated by electric drill disassembly are likely to cause physical injury to the operator, while the work efficiency of manual disassembly is lower. It is very low, which is not conducive to quick disassembly, and the work intensity is high. Although the impact disassembly method can be disassembled quickly, the disassembled rivets are easily attached to the punch, which is not conducive to the operator's multiple disassembly operations and affects the operator's rivets. Batch disassembly work

[0003] For example, the published patent application number "201310470671.X", the patent name "a rivet removal method and its removal device", which is to impact the rivet with a punch, so that the rivet is punched into the blanking hole in the mold base, and the alignment is completed. The removal of rivets, but in the process of dismantling the rivets by the punch for many times, the rivet is easily attached to the punch due to the impact of the punch, which is not conducive to the operator to use the punch to dismantle the rivet for many times. Affect the convenience of the operator
