850e850400 equipment description

Rockliner equipment can carry out anti-wear and maintenance treatment on the surface of drill bit, tap, milling cutter, end milling cutter, punch and die kit, chuck, saw blade, cemented carbide blade and other tools, dies and materials. In addition to manual control, rocklinizer 500 and 600 have automatic gun trigger mechanism, which will be started when the electrode contacts the workpiece. The ultimate effect of rocklinizer surface treatment is to improve productivity and reduce costs, including the cost of vulnerable cutting tools, molds and accessories. If the tools and molds are not replaced due to wear during production, the equipment downtime, the operator's idle time, the operator's setting time, the setting time required to insert new or repaired tools and molds, and the inspection time will be reduced. For any particular production process, the number of tools and molds to be purchased is also reduced. These savings are sufficient to compensate for the purchase of a rocklinizer device.

The use of three kinds of electrodes is as follows: tungsten carbide electrode is used on high-speed steel and other metal surfaces to prolong service life and reduce wear; Titanium carbide electrode (super titanium) seals the surface of the alloy to prevent surface defects. "Rockhard" electrode material is used to build and repair tools with insufficient dimensions by restoring tolerances, and to maintain and prevent surface clamping by repairing tolerances.

Rocklinizer metal surface plating machine

*Easy to operate * portable * low voltage * no welding experience * high selectivity of repair materials * suitable for all ferrous metals. Rocklinizer of the United States uses electric spark discharge technology to make electrode materials form a local wear-resistant super British coating on the metal surface. Its characteristic is that the coating process does not produce sensible heat, so it does not produce various defects caused by heat; The coated wear-resistant materials will not separate or peel off. The coated surface can reach sufficient hardness without heat treatment. If necessary, other surface processing such as fine grinding can be carried out.

Type of electrode

Tungsten based cemented carbide: applied to high-speed steel and other metal surfaces to prolong its effective service life and reduce wear.

Titanium based cemented carbide: tungsten based cemented carbide material that can consolidate or repair wear and make it have longer wear resistance.

Rockhard electrode reinforcing material: it is used to increase the working thickness, repair the workpiece size, repair the tool size through surface plating thickness treatment, make up for the size difference, avoid the sticking of stamping parts and maintain the size of bearings, shafts and other metal surfaces.

Increase productivity / reduce costs

The purpose of this metal surface treatment is to improve productivity and reduce costs. When the tools and molds are not updated due to wear during use, the machine will stop running and the operators will stop working after a period of time. It is necessary to increase the setting and inspection time and the cost of remaking or modifying the tools and molds. If we buy rocklinizer in advance, these problems can be avoided or solved.

technical data

The coating thickness ranges from 0.005mm to 0.175mm. It is adjusted by the machine knob with the thickness of 0.0025mm per grid. Its convenience is that once a certain thickness is adjusted, even if the coating is repeated somewhere on the tool surface, the thickness of the coating cannot be increased, but only the density of the coating can be increased. Higher thickness can be obtained with rocklinizer electrode material.

◆ hardness of coating area 82hrc ◆ hardness of transition layer 75hrc ◆ matrix structure, no change

Typical uses of rocklinizer products

Solution of surface wear and temperature fatigue of die casting die

In the era of increasing emphasis on production efficiency, die-casting die engineers have been looking for ways to prolong the service life of the die. Hot crack is a common problem that can cause the failure of die-casting die. In die casting production, the alternating change of cold and heat on the surface of die casting die will cause the temperature fatigue of die material. When the overheated molten soup is poured into the mold cavity, the die-casting mold will expand due to overheating, while the die-casting mold will shrink when cooling. At the initial stage, the thermal crack formed on the surface of the die-casting die is extremely small. With the progress of production, the thermal crack gradually becomes larger until the molten soup can penetrate into the die-casting die and can not be used normally. Therefore, it is very important to prevent the thermal crack from deteriorating. If the thermal crack can not be controlled, the die-casting die needs to be remade.

The purpose of the test is to reduce the thermal crack and temperature fatigue. The test was very successful. The die was rescued and can continue to be used after about 35000 times of operation. The die can be used for surface discharge deposition of cemented carbide materials again to prolong the service life of the die. The probability of thermal cracks can be effectively reduced by pre discharge deposition treatment on a new die surface. Tungsten based cemented carbide discharge deposition treatment on the die surface before the thermal cracks exceed the limited size can prolong the service life of the die without maintenance.

The machine and electric welding gun manufactured by rocklinizer, Iowa, USA can penetrate and deposit wear-resistant materials on the surface and inside of the mold. The thickness of the coating deposited by discharge in a single operation of the machine is between 0.0025mm-0.10mm, which is adjusted by the machine knob with the thickness of 0.0025mm per grid. The electrode material will produce electric arc and release electric particles when it gently contacts the working surface. It is characterized in that there is no sensible heat in the coating process, and the wear-resistant material on the coating will not separate or peel off. After plating, there is no need for surface treatment such as grinding and fine grinding. Other parts of the mold can also be treated by surface discharge deposition, including sprue, overflow well and escape channel. After discharge deposition treatment on the surface of the escape airway, it can keep cleaner and not easy to adhere. If the width of the small hot crack does not exceed 0.03mm-0.05mm, tungsten based cemented carbide material can cover the hot crack surface.

Cavity drawing die is also a common problem. The temperature expansion coefficient of aluminum die-casting material and zinc die-casting material is much higher than that of iron die-casting material. When the metal material shrinks, it will produce great pressure on the cavity section. After surface discharge deposition treatment on the cavity surface, the cavity surface looks very rough and can not release the die-casting workpiece. However, the rough treated surface is very shallow and thin, The die-casting workpiece cast in actual production is smoother, and the rough surface is less likely to adhere to the die-casting workpiece than the highly smooth surface. The reason is that the lubricant or release agent can be better attached to the cavity surface after the mold cavity surface is treated by discharge deposition, so the die-casting workpiece will be smoother.

The rocklinearizer machine can control the increment with the thickness of 0.0025mm per grid through button setting. The small mold cavity is set with a lower thickness, and the large mold cavity is set with a higher thickness. In order to maximize the service life of die casting die, it is very necessary to test the discharge deposition thickness of tungsten based cemented carbide. Tungsten based cemented carbide electrodeposition is also very successful in reducing die drawing on the reworked die surface.

In many die-casting factories, the mucous membrane phenomenon of zinc die-casting materials and aluminum die-casting materials is one of the reasons for the defective products. The discharge deposition treatment of the gate, escape channel, parting line and die cavity of the die-casting die before production can effectively reduce the mucous membrane problem.

If the ejector pin is treated by discharge deposition on a well functioning cavity, the problem of ejector pin burr can also be significantly reduced. (of course, except for holes that are completely damaged and cannot be repaired) tungsten based cemented carbide materials have also been successfully applied to the electrodeposition of thimbles. The user's report shows that they use less lubricant and the die-casting workpiece is smoother. Users also found that the application of discharge deposition technology to the positioning pin of the equipment makes the parts on the automation equipment fit too tightly, which is also very valuable.

In the die casting industry, the discharge deposition treatment of wear-resistant materials on the metal surface can reduce the following costs and expenses: the time when the machine stops running, the downtime of operators, the need to increase the set inspection time and the cost of remaking or modifying tools and molds. The purpose of surface discharge deposition treatment is to improve productivity and reduce cost.
