Model information and learning points for cylinders

The model of the cylinder is just some numbers and letters in the name, but it fully defines the relevant design elements such as spatial layout, dynamic characteristics, control related, fixed connection and accessories information. We do not necessarily have to recite the specific content of the model, but we must be familiar with its markings and meanings, and be able to proficiently consult the catalog to obtain relevant information.

Don't ignore the exact expression of the model. These strings are filled in the purchase list. For example, the model MB1L32-50 is very different from the MDB1L32-50. In addition to the induction function on the control, even the external dimensions are different. In the cramped institutional space, it may be necessary to modify some workpieces to make way because it cannot accommodate (the wrong type of cylinder), and the extra trouble is beyond imagination.

In addition, standard parts manufacturers provide 3D parts libraries. Be sure to recognize the model when calling, and do not change the model by changing the external dimensions at will. It is especially prone to errors and misinformation.

In general, learning should focus on the following areas:

①Familiar with "dynamic characteristics and spatial layout of cylinder"

For example, where the cylinder output, speed and stroke requirements are not high, or there is no hidden danger of safety accidents caused by power failure (positioning and clamping, etc.), single-acting cylinders can be considered, and double-acting cylinders are generally used in other cases; Pressurized cylinder, if the movement requires precision, you can use a guide rod cylinder or a sliding table cylinder; there are many types of cylinders with the same bore diameter, each with its own adaptation surface, such as the thin CQ2 series for limited space, which can be installed in several directions. CU series.

②Collect or accumulate some experience data

This is helpful for selection, and it is also the content that the standard parts manufacturer's technical after-sales cannot provide you with support. For example, for high-definition interface (HDMI) products, the force of pressing a terminal into the plastic hole is about 10kgf/cm². This belongs to the experience data of the specific product process of each industry. It is impossible for the supplier to give you training. It depends on the product inquiry. Assembly specifications, laboratory tool testing, or the expertise of senior process personnel.

③ Accumulation of basic common sense

Contents similar to this: In general, a single-acting cylinder is equipped with a two-position three-way solenoid valve. If a two-position five-way solenoid valve is used, the corresponding solenoid valve only needs one outlet port and the other is sealed; the double-acting cylinder is equipped with two Position five-way solenoid valve; under the same volume, the stroke obtained by the single-acting cylinder will be small (with a spring inside), so it is more suitable for small strokes.

The selection process of standard parts when designing a specific project is nothing more than flipping through the catalogue and determining the "model information", but whether the selection is appropriate depends on the usual understanding and proficiency of standard parts, so in addition to diligently checking the relevant manufacturer's information , there is no quick fix.
