Inserts - Import export

Reinforced threaded inserts allow threaded holes which have been damaged, torn out or jammed to be used again or to be repaired. This makes it possible to recover scrap and rejects of expensive products. Reinforced threaded inserts are suitable for use in various materials, including light metals and casting. Inserts with internal threads larger than M6 are supplied with four locking pins instead of two. Permissible deviations: The medium tolerance class applies to the threads listed, i.e. 6H for nut threads and 6g for bolt threads. Other dimensions ±0.25 mm. With reinforced threaded inserts we also offer a version with a stronger cross-section for use in applications with greater stress. Technical information see operating instructions for threaded inserts.

Self-tapping threaded inserts for making high-strength, wear-free, vibration resistant screw connections in materials with low shear strength such as aluminium and aluminium alloys, brass, bronze, cast iron, duro and thermoplastics. The threaded inserts are tapered at the bottom and have a cutting slot. By screwing in they cut their own threads inside a receiver hole. This guarantees a completely secure and firm anchoring in the host material. Internal thread D1 acc. to ISO 6H. The threaded inserts with cutting slot spring slightly inwards in the slot region in some materials. This results in a screw locking effect. If this is not desired, we recommend the threaded inserts with a cutting bore.

Material Ballbearing steel 100Cr6. Seal, rubber NBR. Version Sealed on both sides with a spherical outer ring. Can be relubricated. Note The internal construction of the insert bearings corresponds to that of standard Series 6200 and 6300 radial ball bearing. However, they have wider inner rings for easier fastening on shafts. The inner rings are manufactured with a plus tolerance. This results in transition or press fits when using shafts with htolerances. The shaft is secured by 2 grub screws positioned 120° apart on the inner ring. The insert bearings are ready to install and are permanently lubricated with a suitable ball bearing grease. In normal applications, relubrication is not necessary.

Grippers and inserts are ideal for use in clamping arms, gripping systems, clamping fixtures, clamping jaws and self-aligning pads. The use of grippers allows the transfer of very high torque values and above average grip, even with hard materials and surface irregularities. Form O: The abrasive diamond surface is bonded firmly to the base. It is ideally suited to supporting smooth or slippery applications with a minimum of clamping pressure. This allows the diamond particles to get a firm grip on a very small area with minimum damage to the surface. The diamond surface offers excellent wear resistance. Form P: The polyurethane surface is vulcanised firmly to the ball. It is abrasion-resistant and does not discolour. It offers optimum protection against damage to delicate surfaces. The pearl-like surface gives a firm grip and allows air to escape so as to prevent any suction effect between the contact surface and the self-aligning pads.

Tempered and black oxidised. Note: The pressed in plastic inserts offer optimal damage protection for sensitive workpiece faces.

The required torque is set by a set screw and a graduated scale. The set value can be secured using the lateral clamping screw. When the set torque is reached the grip audibly and palpably releases. The loosening torque is higher than the tightening torque so that the torque handle can be released without any problems. The internal thread version has a hole in the set screw so that the torque handle can also be used on threaded rods. Set torque accuracy ± 5%. On request: Other thread lengths.

The pressed in plastic inserts offer optimal damage protection for sensitive workpiece faces.

Body tempered, black oxidised. Ball hardened, bright. Inserts: Form C, F hardened, black oxidised. Form M with carbide serrations, black oxidised. Form K white. Form E hardened, bright. Form O diamond impregnated surface comparable to 100 grade abrasive grit. Form P polyurethane surface, hardness 60 Shore. Note: Self-aligning pads are used to support and clamp unmachined and machined workpieces. In addition, they serve as stops, supports and thrust pads in fixtures and toolmaking. The ball can be removed from the housing by applying light pressure to the socket head screw. Ball secured against rotation. Advantages: Highly cost-effective as inserts can be exchanged. The built-in O-ring holds the ball in place and keeps dirt and foreign particles out, ensuring uniform movement.

These types of machines have been developed for largeseries injection molding involving parts with inserts, for example the injection molding of battery pack seals. Based on its longstanding experience in this field, REP offers a comprehensive range of machines with largesized heating plates and adjustable configurations to fully comply with the technical specifications of each application and all client’s needs.

Machine features Clamping force 4,000 kN. Platen size 750 x 800 x 80 mm. Injection volume 2,000 cm³ or 5,000 cm³. The H610 allows Automated productions. Injection molding (more or less simple parts). A small footprint and height. An optimized cycle time. etc.

Designed for the manufacture of highvoltage insulators (550 kV), this press is one of the largest presses made by REP. The dimensions of the parts to be injected explain the huge size of the press 660 mm in diameter, 2,600 mm long, moulded in one go. The production of a complete insulator is therefore performed in one or two cycles, thus significantly increasing the profitability and reliability of the parts.
