Elevator hollow slide

The unwinding part adopts a double cantilever structure, the size of the coil core is adjusted by manual tension (φ480~φ520), and the leveling part drives the coil to stop by a brake belt

Main forming parts of elevator hollow slide rail

It is mainly composed of guide frame, molding parts, transmission parts and so on.

Guide frame: It is a guide device for the sheet to ensure that the sheet is straight and centered into the molded part.

Forming parts: Forming parts are mainly composed of frame, side plate, mold (roller) support part and rolling mold.

The frame is welded with section steel, the structure is firm, the deformation is small after aging treatment, and the internal stress is eliminated. The finished desktop (gantry engraving and milling), flatness ±0.2MM, to ensure the strength, rigidity, stability and accuracy of the equipment.

The side plates are all made of 45# steel, with excellent materials and smooth surface after processing. The thickness of the main side plate is 70mm, and the thickness of the secondary side plate is 45mm.

The main component of the mold supporting part-the rolling shaft is made of 45# steel, which is finished by fine turning and fine grinding after quenching and tempering. The size of the matching part is accurate, and the bending performance is good. The shaft end working bearing adopts the products of well-known domestic and foreign manufacturers to ensure the stability and service life of the work.

The rolling mold adopts foreign advanced COPRA software for CAD design. The material is GCr15 steel, the surface hardness reaches HRC58~60 after heat treatment, and the wear is small. After strict procedures and craftsmanship, using fine CNC machine tools, the dimensional accuracy is IT6~IT7, the surface roughness is 1.6μm or greater, the size after molding is accurate, and the working surface is beautiful. The rolling mold is installed on the roller shaft and locked with a nut, which is stable and reliable. Forming 14-16 sets of forming rolls, the hole diameter (roller shaft diameter) is φ50, and the smaller roll diameter is φ110.

Straightening: adopts five-wheel straightening mechanism.

After the design of the whole machine is reasonable, the forming roller adopts multiple rollers to form gradually. After molding, the product size is accurate and the surface is beautiful.

The driving part adopts reducer and coupling to drive each other, the roller is driven by universal coupling, center distance a = 300, reduction ratio i = 30, worm gear box, main motor 7.5KW (Nanyang Motor) frequency conversion speed control.

The spindle material is 45# steel, which is processed and finely ground after heat treatment and quenching.

Cutting overview: The working mode of the system is divided into the following three: when all the conditions of the system power supply are met, the system can be started, and the system should enter the manual mode after starting. And the automatic production mode is usually used in the production process

When the conditions required for the normal operation of the manual mode system are met, the system enters the manual mode after booting, but the actual production uses the automatic mode. In manual mode, when the forward button is pressed, the tool post moves in the positive direction. Press the reverse slow forward button, the tool post moves in the opposite direction, and then press the zero button, the tool post returns to the zero point.

Automatic mode This is the operating mode set for normal production. According to the set cutting length, the knife holder will automatically move with the material and cut the material according to the set length, and then the knife holder will return to the original position. The cutting speed is determined by the automatic calculation of the set length and material speed. After meeting the specified environmental conditions, press the "Auto Mode" button, and the system can enter the automatic operation mode.

Automatic control system The entire production line is centralized and fully automatic. The leveling servo feeder and the hydraulic punching machine are connected together, and each action is automatically completed.
