SPECIFICATIONS

INTENT OF USE

The 74290 Tool is designed to convert round holes in to hexagonal holes. The latter are produced by means of a drill. Then the tool, equipped with punch and reference die, is to be inserted into the hole, where it removes other material in order to obtain a hexagon hole, ready to receive threaded hexserts.
In this way it is possible to easily and rapidly install threaded inserts which, owing to the hexagon profile, guarantee the on rotation of the joint, with evident advantages regarding the production process and the offered performances, compared to round threaded inserts or other competitor technologies (nuts, welded nuts, etc…).
The use of this tool for threaded inserts enlarges the range of application (up to now it was restricted to the employment of pre punched sheets) for box type design pieces, low volume series production and in situ applications.
For further details regarding the preparation of the hole in relation to the type of material and the thickness, see page 12.
DO NOT use under wet conditions or in the presence of flammable liquids or gases.

PUTTING IN SERVICE

IMPORTANT – READ THE SAFETY RULES ON PAGE 4 – 6 CAREFULLY BEFORE PUTTING INTO SERVICE.

• Select relevant size nose equipment and install.
• Connect the placing tool to the air supply. Test pull and return cycles by depressing and releasing the trigger 40.
• Set the tool for desired stroke/pressure.

CAUTION: Correct supply pressure is important for proper function of the installation tool. Personal injury or damage to equipment may occur without correct pressures. The supply pressure must not exceed that listed in the placing tool specification.

PRELIMINARY OPERATIONS

Every day, before using the tool, carry out the operations described in section “LUBRICATION”. Before connecting the tool to the air supply, blow compressed air through the feed pipe, in order to eliminate any trace of condensation water or foreign matter. LUBRICATION: Prior to connecting the air hoses, pour a small quantity of light hydraulic oil into the air admission fitting.

AIR SUPPLY

All tools are operated with compressed air at an optimum pressure of 5 and 7 Bar. We recommend the use of pressure regulators and automatic oiling/filtering systems on the main air supply. These should be fitted within 3 metres of the tool (see diagram below) to ensure maximum tool life and minimum tool maintenance.
Air supply hoses should have a minimum working effective pressure rating of 150% of the maximum pressure produced in the system or 10 bar, whichever is the highest. Air hoses should be oil resistant, have an abrasion resistant exterior and should be armoured where operating conditions may result in hoses being damaged. All air hoses MUST have a minimum bore diameter of 6.4 millimetres or 1/4 inch.
We recommend to operate the tool at the minimum pressure necessary to obtain the requested hole, to consume less air and the maximum tool life is ensured.

Read servicing daily details page 13.

TOOL CONFIGURATION

The tool is able to punch hexagon holes, designated to receive metric threaded hexagon inserts type M4, M5, M6, M8, M10. According to the hole to be realized, the appropriate equipment can be ordered under the relative part number (see Table on Page 120.

PRINCIPLE OF OPERATION

Connect the tool provided with the appropriate equipment to the air supply (see table of recommended air pressures in relation to the material to be punched).

Fig.1 Workpiece with round hole.

Fig.2 Insert the punch fixed onto the 74290 Tool into the previously drilled round hole.

Fig.3 Depress the trigger. In this way the rod 24 advances and the punch blades extend on the hole walls, now the punch is ready to stamp.

Fig.4 In the following the punch removes excess sheet material to create a hexagon hole suitable to place the hexagon insert. At the end of this phase the punch retracts from the hole and removes the punching scrap. In general the scrap is ejected via the punching effect and the return of the punch into the rear position. Scrap will be expelled without jamming the punch.

Fig.5 The workpiece, with the hexagon hole stamped by the 74290 tool, is now ready to fit a threaded Hexsert.

• Make sure that no scraps are left on the punch.
• The tool now is ready for a new operating phase.

Transforms round holes into hexagonal holes for use of Hexsert® threaded inserts M4 – M10. Thickness range of workpiece (respective punch equipment has to be ordered seperately):

Aluminium| M4, M10:

M5 – M8:

| 0.5 – 2.5 mm

0.5 – 4.5 mm

---|---|---
Steel| M4:

M5 – M10:

| 0.5 – 1.5 mm

0.5 – 3.0 mm

Stainless Steel| M4 – M10:| 0.5 – 1.5 mm

OPERATING SEQUENCE

• Place the punch mounted onto the 74290 Tool tool inside the round hole.
• Fully depress the trigger of the 74290 tool. The piston extends the punch and automatically perforates the sheet material. In doing this, a punched hexagon hole is produced. A threaded Hexsert can now be inserted by means of the Stanley Engineered Fastening tool models 74200 and 74202.
  

NOSE ASSEMBLIES

It is essential that the correct nose assembly is fitted prior to operating the tool. By knowing the details of the fastener to be placed, you will be able to order a new complete nose assembly using the selection tables on page 12.

FITTING INSTRUCTIONS
