DSM NEW tools are mechanized tools powered by electric motors or electromagnets, driving the working head through a transmission mechanism; these are called power tools. They are hand-held operating tools that use low-power electric motors or electromagnets as the power source to drive the working head via a transmission mechanism. Power tools are divided into handheld and portable types. Handheld power tools are more flexible, convenient, and widely used; many varieties have become essential tools for production and daily life. There are numerous power tool brands. Based on function and application, they are mainly classified into metal cutting power tools, grinding power tools, assembly power tools, and railway power tools. Common power tools include electric drills, electric grinders, electric wrenches and electric screwdrivers, electric hammers and impact drills, concrete vibrators, and electric planers.

DSM NEW tool classification

1) Squeeze-exhaust suction cups expel all air from the cup by downward squeezing force, creating a negative pressure state inside to hold the workpiece. They offer advantages such as simple structure, light weight, and low cost. However, the suction force is not large, so they are mostly used for workpieces with small dimensions that are thin and light. 2) Airflow negative pressure suction cups use an airflow control valve to inject compressed air from an air pump through a nozzle, forming a high-speed jet that removes air from the suction cup cavity, creating negative pressure to hold the object. If compressed air is available at the worksite, using this type of suction cup is convenient and low-cost. 3) Vacuum pump exhaust suction cups connect the vacuum pump to the suction cup via an electromagnetic control valve. When the control valve evacuates air, the air in the suction cup cavity is removed, creating negative pressure to hold the object. Conversely, when the control valve connects the suction cup to the atmosphere, the suction cup loses suction and releases the workpiece. The suction force of vacuum pump suction cups mainly depends on the size of the suction area and the degree of vacuum in the inner wall of the suction cup (referring to the thinness of the air in the inner q cavity). This type of suction cup is reliable and provides strong suction, but requires a vacuum pump and airflow control system, resulting in higher costs. 4) Mechanical clamping type: The structure of a straight-bar dual-cylinder translational gripper involves fingers mounted on a straight bar equipped with finger mounting seats. When pressurized gas enters the rod-side chambers of the single-acting dual cylinders, the two pistons move toward the center to clamp the workpiece; when no pressurized gas enters, springs push the two pistons outward to release the workpiece. A flow divider valve is installed in the cylinder intake line to ensure synchronous movement of the two pistons. This type of end effector is used in loading and unloading assembly workstations.

DSM NEW tool selection

1) Distinguish between household and professional use based on needs. Most power tools are designed for professionals, so differentiate between professional and general household tools when purchasing. The difference usually lies in power; professional tools have higher power to reduce workload for professionals, while household tools handle smaller projects with less workload, so high input power is not required. 2) The outer packaging of the tool should have clear patterns, no damage, a sturdy plastic box, and durable latches for opening the plastic box. 3) The appearance of the tool should have uniform color; plastic parts should have no visible flow marks or indentations, scratches, or collision marks. Assembly misalignment between housing parts should be ≤0.5mm. Aluminum casting coatings should be smooth, aesthetically pleasing, and undamaged. The entire machine surface should be free of oil and stains. When held by hand, the switch handle should be flat. The cable length should generally be no less than 2 meters. 4) The nameplate parameters of the tool should match those on the CCC certificate. The manual should include the detailed address and contact information of the manufacturer and production factory. The nameplate or certificate of conformity should include a traceable batch number for the product. 5) Hold the tool by hand, connect to power, and frequently operate the switch to start the tool repeatedly. Observe whether the on/off function of the tool switch is reliable. Simultaneously observe whether there are any abnormalities in nearby televisions or fluorescent lights to confirm whether the tool is equipped with an effective radio interference suppressor. 6) Run the tool under power for one minute. While running, hold it by hand; you should not feel any abnormal vibration. Observe the commutation sparks; the commutation spark level should not exceed 3/2 grade. Generally, looking inward from the tool's air inlet, there should be no obvious arcing on the commutator surface. During operation, there should be no abnormal noise.

DSM NEW tool usage

1) Non-sparking tools provide safety assurance for personnel working in flammable, explosive, and corrosive environments, enhancing social safety and allowing workers to operate with greater peace of mind. After daily use, non-sparking tools require proper maintenance, which is crucial for their service life. Improper maintenance may prevent the tools from serving us for a long time. First, store the tools in a dry place to protect working components from damage. In daily work, after continuous striking 20 times, treat the surface attachments on the tools, wipe them clean before reuse, and avoid continuous use to prevent overheating due to prolonged friction, which could damage the tool products. 2) After use, wipe off surface dirt and deposits, and store in a dry, safe place. 3) For striking tools, do not strike continuously; allow appropriate intervals after ten strikes, and promptly remove debris adhering to the product parts before continuing use. 4) Wrench-type products must not be used with excessive force. Do not use sleeves or bind other metal rods to extend the lever arm, nor use hammering methods (except for striking wrenches) to tighten fasteners. 5) Cutting-edge tools should be gently brought into contact with the grinding wheel in a water trough for sharpening. Do not apply excessive force or maintain contact with the grinding wheel for too long. 6) In actual operation with chiseling and striking tools, clear site debris and corrosive oxides from the working surface to prevent third-party impacts. Based on the above performance and usage, aluminum-copper alloys are more suitable for normal pressure equipment and environments with less stringent explosion-proof requirements (such as gas stations and small oil depots). Beryllium-copper alloy non-sparking tools are suitable for applications such as refineries, gas transfer stations, gas extraction plants, and drilling teams. 7) Remove surface oil from various products before use, and refer to the instructions for steel tools.
