Description

Technical Field

[0001] The utility model relates to the technical field of trimming machines, in particular to a freezing trimming machine. Background Art

[0002] The trimming machine is a device used to repair the burrs on the surface of a workpiece, while the frozen trimming machine uses the characteristics of rubber at low temperatures and the brittle gradient caused by the thickness difference between the overflow and the main body to complete the trimming. That is, it seizes the time difference between the overflow being brittle and the main body not being brittle, and applies external forces such as friction, impact, and vibration to the product to be repaired to remove the overflow, while the product body is still in an elastic state and is not damaged.

[0003] The inventor discovered in his daily work that in the process of using a frozen trimming machine to process workpieces, most of the existing frozen trimming machines on the market use buckles to fix the cabinet door, thereby squeezing the rubber ring on the cabinet door for sealing. Since the fastening effect of the buckle is limited, when the cabinet door is in a closed state, the squeezing effect on the rubber ring is poor, resulting in a loose fit between the rubber ring and the cabinet body, causing a gap between the cabinet body and the cabinet door, resulting in some cold air overflowing through the gap during the operation of the equipment.
