4 / 6 page 408- 8910 Hydraulic Crimping Head 1673672- 1 Rev B 4 of 6 Tyco Electronics Corporation 7. INSPECTION/MAINTENANCE Make sure hydraulic pressure is released and power supply is disconnected before following inspection and maintenance procedures, unless otherwise specified in the procedure. Each crimping head is assembled and inspected before shipment. It is recommended that the crimping head be inspected immediately upon its arrival at your facility, and at regularly scheduled intervals, to ensure that the crimping head has not been damaged during handling. Frequency of inspection depends upon the following: care, amount of use, and handling of the head; type and size of products crimped; degree of operator skill; and environmental conditions. 7.1. Cleaning Remove accumulations of dirt and grease on the crimping head, especially in areas where dies are installed and terminals are crimped. Clean the entire head frequently with a clean, lint--free cloth. 7.2. Visual Inspection Refer to Figure 6 and proceed as follows: 1. Visually inspect die closure surfaces for chipped, pitted, or flattened areas. Figure 6 Chipped Area Pitted Area Flattened Area Check These Areas for Cracks Check for Excessive Wear at all Pivot Points 2. With hydraulic pressure released, inspect the assembled head for nicks, scratches, and cracks. Inspect for cracks especially at the corners of the yoke and around the top of the cylinder. 3. Inspect pivot pin holes and latch pin holes for wear. Replace parts, as needed. 4. Activate power unit. Raise ram to UP position. Inspect flat and round surfaces of ram for galling (fretting or wear by friction), cracks, or oil leakage. Release pressure and make sure that ram retracts smoothly. 5. If head shows evidence of galling, cracks, oil leakage, or rough cycling, return the crimping head to for repairs. (Refer to Section 8, REPLACEMENT AND REPAIR). It is recommended that the head be returned to Tyco Electronics once a year (or every 7,500 cycles) for magnetic particle inspection. Refer to Instruction Sheet 408--8909. 7.3. Die Closure Inspection Every crimping head die set is inspected for proper die closure before shipment. However, the dies should be inspected for excessive wear periodically. Die closure is accomplished using GO/NO--GO plug gages. Suggested plug gage design and GO/NO--GO dimensions are shown in Figure 7. Tyco Electronics neither manufactures nor sells plug gages. 1. Clean the oil and dirt from the closure surfaces, and plug gage members. 2. Lock the desired nest in the crimp position and raise the indenter to the full UP position, as shown in Figure 8, Detail A. 3. With the indenter positioned at the full UP position, inspect the die closure using the appropriate plug gage. Hold the gage in alignment with die closure and carefully insert, without forcing, the GO member. See Figure 8. The GO member must pass completely through the die closure as shown in Figure 8, Detail B. 4. Try to insert the NO--GO member. The NO--GO member may enter partially, but must NOT pass completely through the die closure. See Figure 8, Detail B. 5. If the die closure meets the GO/NO--GO gage conditions, the die closure is considered dimensionally correct. If the die closure does not conform with the GO/NO--GO gage conditions, contact your local Tyco Electronics Representative. DANGER NOTE i NOTE i |
