When we process the cabinet with Taicang sheet metal parts, we should not only master the size of the cabinet, but also check the shape of the equipment to ensure that it matches the selected support. A sturdy cabinet can hold up to 450 pounds, so check the tools used to take out the sheet metal processing equipment. For example, a door or a trolley. A good cabinet is equipped with wheels, so you just need to install the equipment and push the cabinet to a suitable place.

Measure the size of the room and the height of the ceiling, door and elevator through which the cabinet passes. In addition, considering the various types of equipment in the cabinet, ensure that the cabinet is placed close to the power supply, network cable socket and communication socket. Check the opening angle of the cabinet door when opening and closing the cabinet. The standard cabinet door is opened on the right and the door shaft is on the left. Of course, the opposite situation is not ruled out. All doors and side plates shall be easily opened for maintenance.

When you want to install the equipment cabinets into an existing cabinet group, you can arrange the cabinets next to each other in a row, which is safe and tidy. However, for various reasons, some cabinet groups cannot be added, or only several accessories can be added. The good cabinet group model shall be fully expandable and equipped with all necessary hardware. The cabinet side plate can be removed and the cabinets can be connected with each other in a row with screws.

Solutions to the decline of machining accuracy of NC machine tools

Automobile sheet metal processing: the solution to the decline of machining accuracy of NC machine tools. The decline of machining accuracy of parts processed by NC machine tools is mainly due to the fact that the symmetry of feed dynamic tracking error value between axes is not adjusted in a good state.

There are two reasons for this failure: one is that the feed dynamic tracking error between axes is not adjusted well when the NC machine tool is installed and adjusted; Second, after the machine tool is used for a period of time, the transmission chain of each shaft changes (such as lead screw clearance, pitch error change, axial movement, etc.).

These two reasons can be solved by readjusting and changing the clearance compensation.

Sheet metal processing is one of the commonly used processing technologies, which contains many processes, and welding is one of them. What should we pay attention to when implementing welding technology for such a special workpiece as sheet metal workpiece?

There are many welding technologies involved here, including soft welding and hard welding. The former uses low melting point metal to bond two or more metals together. As long as the joint components are placed adjacent to each other, heat the joint part, and inject molten solder into the joint part; The latter will get higher bonding strength.

Observing the two welding technologies, the big difference is the melting point of the filler material injected into the joint. Although the hard welding joint strength is relatively high, due to the high heat, it may lead to adverse phenomena such as component deformation, melting or bending, warping, corrosion and so on. Therefore, the welding technology must be selected according to the requirements of the workpiece.

Classification of sheet metal processing and welding methods:

1 Classification of welding methods: welding methods mainly include arc welding, electroslag welding, gas welding, plasma arc welding, fusion welding, pressure welding and brazing, and sheet metal products are mainly arc welding and gas welding.

2. Arc welding has flexibility, mobility and wide applicability, and can be welded in all positions; The utility model has the advantages of simple equipment, good durability and low maintenance cost. However, the labor intensity is high and the quality is not stable enough, which depends on the operator's level.

It is suitable for welding carbon steel, low alloy steel, stainless steel, copper, aluminum and other non-ferrous alloys above 3mm.

3. The temperature and properties of gas welding flame can be adjusted. The arc welding heat source is wider than the heat affected zone, the heat is not as concentrated as the arc, and the productivity is low.
