Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Please refer to the figure, a technical solution provided by the utility model:

[0026] like Figure 1-Figure 4 As shown, a station conversion device for a double-station crucible forming machine includes a fixing device 6, the middle part of which is connected to a forming device 1, a floating roller group 3 is fixed on the fixing device 6, and a mobile platform 2 is provided on the upper part of the floating roller group 3; ejection cylinders 4 for ejection are fixedly installed on the left and right sides of the lower bottom surface of the fixing device 6, and an outlet hole 5 for ejection of the ejection cylinder 4 is provided on the mobile platform 2. The ejection cylinder 4 can pass through the floating roller group 3 and eject at the outlet hole 5 to realize mobile stripping.

[0027] The contact device of the mobile platform 2 adopts a floating roller group 3 to reduce the friction force on the contact surface of the mobile platform 203 during the movement process, thereby increasing the service life of the mobile platform 203.

[0028] After the entire processing procedure is completed, the slide beam 102 rises, the floating roller group 3 rises, and the ejector cylinder 4 pushes the material out of the work station through the rise of the piston rod to achieve mobile material removal.

[0029] like Figure 2 As shown, the forming device 1 includes a lower beam 7, which is fixed to the lower part of the middle part of the fixing device 6, and the lower beam 7 is connected to the upper beam 101 through a column 103, and a sliding beam 102 that can slide up and down is provided on the column 103. The upper beam 101 is located above the device and plays a guiding and positioning role for the device in terms of structure. The sliding beam 102 is located below the upper beam and slides up and down on the surface of the column 103 to buffer pressure and vibration, thereby realizing the forming process of the material, and buffering the pressure and vibration generated during the processing, to ensure the normal operation of the device.

[0030] like Figure 1 , Figure 2 , Figure 4As shown, the floating roller group 3 includes a plurality of rollers, the middle of the roller is a roller shaft 301, the outside of the roller shaft 301 is provided with a roller sleeve 302, and the two ends of the roller shaft 301 inside the roller sleeve 302 are provided with roller bearings 303; the two end heads of the roller shaft 301 are arranged on roller supports 603, and the roller supports 603 are arranged on the fixing device 6.

[0031] A pair of roller bearings 303 are provided at each end of the roller shaft 301. They provide higher support stiffness, share the load, and extend the service life of the bearings. The roller bearings 303 are insensitive to lubrication interruptions, and the roller sleeves 302 increase the stability of the floating roller group 3, improve the working accuracy, and ensure the normal operation of the device.

[0032] The mobile platform 2 includes a mobile table 203, one end of which is connected to the mobile cylinder 201 through a connecting rib plate 202. The mobile cylinder 201 is extended and retracted to drive the mobile table 203 to move along the guide support 602 through the connecting rib plate 202, so as to realize the conversion of the processing station, and then realize the reciprocating exchange of the double stations, reduce the operation steps in the processing process, and improve the production efficiency.

[0033] The movable table 203 provides support and fixation for the workpiece being processed.

[0034] like Figure 4 As shown, the roller support 603 is provided with a guide support 602, and the upper part of the guide support 602 is provided with a pressure plate 601. The pressure plate 601 and the guide support 602 form a slot, and the mobile platform 203 is stuck in the slot and can move along the guide support 602. The slot can enhance the ability to withstand radial loads and prevent lateral displacement, so that the mobile platform 2 runs more smoothly and the structure of the connection with the pressure plate is more compact.

[0035] When the device is in use, the upper beam 101 is supported by the upright column 103, and the sliding beam 102 located below the upper beam 101 is moved up and down to process the crucible workpiece.

[0036] The floating roller group 3 reduces the friction force on the contact surface of the moving platform 203 during the movement process, thereby increasing the service life of the moving platform 203.

[0037] The connecting rib plate 202 connects the moving cylinder 201 and the moving platform 203, and the left and right translation of the moving platform 203 is realized through the movement of the piston of the moving cylinder 201, thereby realizing the reciprocating exchange of the double stations, reducing the operating steps in the processing process, and improving production efficiency.

[0038] The floating roller group 3 is connected to the fixing device 6 through the roller support 603. The roller shaft 301 is fixed with two pairs of roller bearings 303 to provide higher support stiffness, share the load, and extend the service life of the bearing. The roller bearings 303 are insensitive to lubrication interruptions. The roller sleeves 302 increase the stability of the floating roller group 3, improve the working accuracy, and ensure the normal operation of the device.

[0039] After the entire processing procedure is completed, the slide beam 102 rises, and the ejector cylinder 4 pushes the material out of the work station through the rise of the piston rod, thereby realizing mobile material removal.
