Detailed Description
The invention will be described in further detail with reference to the drawings and the detailed description.
The invention relates to a stamping forming device of a W-shaped copper water stop cross joint, which comprises a supporting frame 8, an operation platform, a bearing die and the like; the lower stamping die 5 is fixed on an operation platform of the supporting frame 8, the upper combined stamping die is positioned by four supporting slide bars 3 and corresponds to the lower stamping die 5, the upper combined stamping die consists of a cross groove stamping die 13 for stamping a cross nose bridge and a side plate stamping die 12 for stamping a side plate with a folded periphery downwards, the two dies are positioned on the four supporting slide bars 3 and can be connected together through clamping pieces (a first clamping piece 14 and a second clamping piece 19), and the upper combined stamping die can be further fixed through clamping pieces 15. The hydraulic cylinder 2 is fixed on the top plate 1, the hydraulic cylinder 2 is fixed with the upper combined stamping die, the clamping piece 15 is taken out firstly during stamping, the cross bridge is stamped out, then the clamping piece 15 is installed, and the lower folding side plate is stamped out. Because the stamping depth of the cross bridge of the nose is large, the stamping forming W-shaped copper water stop cross joint avoids the tearing of a copper water stop sheet caused by one-step stamping forming and cannot be formed, and the stamping is completed in two steps, namely the stamping forming of the cross bridge of the nose is completed in the first step, the stamping forming of the lower folding side plate is completed in the second step, and the stamping qualification rate of the W-shaped copper water stop cross joint is ensured.
The control box 7 and the operation buttons 6 are arranged on the operation platform, and three buttons of running, scram and stop are arranged. The lower stamping die 5 is a special-shaped cross-shaped concave die, the concave die positions are all round angles, and the copper sheet is prevented from being torn due to stress concentration of the square copper water stop sheet 16 in the stamping process.
The invention discloses a stamping forming process of a W-shaped copper water stop cross joint, which comprises the following steps: firstly, heating and softening the square copper water stop sheet 16, then putting the square copper water stop sheet 16 between an upper stamping die and a lower stamping die, and stamping the square copper water stop sheet without installing the clamping piece 15 for the first time, wherein only the cross groove stamping die 13 in the upper combined stamping die is used for stamping to form a cross nose bridge of the joint; the clamping piece 15 is installed for the second time, so that the cross groove stamping die 13 and the side plate stamping die 12 synchronously finish stamping downwards, and the stamping forming of the W-shaped copper water stop cross joint is realized; and finally, lifting the upper stamping combined die, and taking out the formed W-shaped copper water stop cross joint. The stamping forming from the square copper water stop sheet 16 to the formed copper water stop joint 17 is completed.
In order to ensure the alignment of the upper die and the lower die and the accurate positioning in the stamping process, four identical support slide bars 3 are specially arranged, and the upper stamping combined die is positioned in the four identical support slide bars 3, so that the purpose of accurate stamping is achieved.
