Commonly known as mechanical parts handlebar lever operation, joystick, etc., are widely used in a wide range of machine tools, machine tool, woodworking machinery and welding, hydraulics, printing and packaging, textiles, light industry, mining, automotive, food, medical and other mechanical equipment to do mechanical operation lever use
Divided according Handle Material: Bakelite handle, iron handle, zinc alloy handle, steel handles and so on.
Performance can be divided in accordance with the handle: handle, turn the handle, locking handle, adjustable handle, folding handle, handle sets, handle bars, handle seat, shaking the handle, three ball handle and so on.
The lever shape can be divided into: handle, straight handle, turn the handle, turn the handle surface, small rotating handle, chrome-plated steel handle, Seven handle (adjustable bit tight grip), folding handle, long handle sets, handle sets, oval handle sets, handle the ball, handle bars, seat handles, handle the disc holder, locking handle seat, seat positioning handle, three ball handle, positioning handle, ball handle, handle, etc. taper column
Stainless stee knurled handle
Machinery and accessories industry handle there are two main types of plastic material, steel. There machining of steel and castings distinction. Plastic handle thermosetting plastics and thermoplastics have the points. So here is not to talk about specific details, here is a look at how the main four processes to identify handle slightly superior.
Steel lathe:
1, measuring the size of the handle is executed in strict accordance with industry standard processing (emphasis see mounting dimensions).
2, the handle screw threaded part of the frustration out of braces or board machine, where we should focus distinction, rub out the screws precision, hardness and surface roughness is not very good.
3, the handle is smooth burr surface treatment, rust treatment process is through.
Turning the handle post-casting processing
1, see the handle mounting location, whether the handle screw accuracy and the overall size of the standard in full accordance with the mechanical processing.
2, the handle surface is rough, with trachoma.
3, the handle is smooth burr surface treatment, rust process is through.
Thermosetting plastic handle
First, some raw materials for the production of thermosetting plastic Bakelite handle, commonly known as bakelite, bakelite, English abbreviation PF. Bakelite handle with insulation, abrasion, not to hurt the hand, hardness, pollution, corrosion resistance and other properties, and surface brightness.
1, watch bakelite handle surface is bright burr.
2, handle with screws, nesting is enough grade, precision and rust process is through.
3, the overall measurement of the mechanical portion of the handle there is not in accordance with the industry standard processing.
4, the handle screw thread is embedded in bakelite handle nested inside, it is best to do a destructive test, the metal part of the firmness with bakelite handle portion. In general, embedded in the handle where the screws have a hexagonal nut, whole thread to prevent the screws in the handle was rotated 360 degrees or off, some manufacturers will add a hex nut on the basis of the whole tooth hexagonal nut on the bolt enhance its robustness.
Detection thermoplastic handle and bakelite handle the same.
Thermosets and thermoplastics handle grip performance differences:
Thermosets high mechanical strength, surface brightness. Good corrosion resistance, temperature range of conditions, it is not deformed, but it is more brittle and can not withstand the heavy pounding.
A wide range of thermoplastics, in terms of performance acid, alkali, chemical resistant, abrasion, temperature and other advantages and disadvantages, please refer to the site to learn more about technical article describes common plastic material properties, which in common with bakelite comparison: there toughness, excessive force will be much too little deformation, but will not break anymore.
fisheye Mechanical operating handle
Ball handle standard JB / T 7270.8-1994, material is generally 35 steel, Q235A; surface treatment methods have blasted chrome, polished chrome oxide; divided into A 180 ° parallel to the handle and the B-type ball 20 ° oblique corner head handle.
