[0025] The bottom support platform 3 comprises a middle platform 31, and a plurality of support plates 32 are arranged on each of the two parallel side stands of the middle platform 31. The support plates 32 on each side stand are arranged at equal intervals, and a spacing area is arranged between two adjacent support plates 32. A tray 33 is arranged in the spacing area, and the tray 33 is connected with the support plate 32. The tray 33 can move in the spacing area towards the middle platform 31 or away from the middle platform 31. At this time, the tray 33 and the support plate 32 form a side support assembly. The extension directions of the two side support assemblies are opposite, and the middle platform 31 is located between the two side support assemblies. When the workpiece is placed on the middle platform 31, the side of the workpiece is in contact with the tray 33. A flow channel 34 is arranged on the middle platform 31. After the workpiece is placed on the middle platform 31, the space where the flow channel 34 is located forms a cooling liquid flow channel.
