The structure of the crimping pliers and mold of the crimping machine

To meet the strength requirements of a large-tonnage crimping machine, the volume and weight of each component should be as small as possible, and the key components should be analyzed through finite element calculations; hydraulic cylinders usually work under high pressure, and key research needs to be done on the sealing of the cylinder body; based on 1250m㎡ The length of the large cross-section wire connection tube or the tension-resistant aluminum tube can reduce the number of times of molding and improve the quality of molding, which is convenient for construction. The crimping die, the caliper body piston and the mold positioning block are designed with a groove structure. There is an annular groove in the middle of the crimping die. A telescopic positioning pin is designed on the piston and the mold positioning block. After the mold is installed in place, the telescopic positioning pin is stuck in the The inside of the ring groove of the mold prevents the mold from moving back and forth during the crimping process, which is safe and reliable. At the same time, the clamp head is equipped with a mold positioning check block to check the mold positioning and facilitate the replacement of the mold. The axial gap between the mold positioning check block and the mold is 1mm; the mold positioning check block can be rotated at an angle of 45° with the check knob; Move the piston to the lowest end, and then rotate the inspection block to the 45º angle position. At this time, the mold can be replaced. After the mold is replaced, the inspection block is rotated in place. If the mold is not installed, the positioning inspection block is in the process of rotation. There will be interference.
