[0002] In today's industrial production, vacuum chambers are widely used in the processing and machining of a variety of workpieces. These workpieces include but are not limited to metals, plastics, glass and composite workpieces. Vacuum chamber technology can effectively prevent the workpiece from oxidizing during high temperature or chemical treatment by creating an oxygen-free or low-oxygen environment, thereby ensuring the quality and performance of the workpiece.

[0003] However, traditional vacuum box equipment often has some shortcomings in practical applications. Operating these devices is usually cumbersome, and the complex operation process not only reduces production efficiency, but also increases the risk of human error. Traditional vacuum boxes are inefficient in cutting workpieces, mainly because their mechanical structure and control system are relatively complex, and they cannot achieve fast and accurate cutting. This not only prolongs the production cycle, but also increases the waste of workpieces. The space utilization rate of traditional vacuum boxes is not high, which limits the expansion of production scale.

[0023] See also Figure 1 , Figure 2 and Figure 3 As shown, the present invention provides a new type of external drag cutting vacuum box technical solution: comprising two side support plates 11, the tops of the two side support plates 11 are commonly connected to a top support plate 12, an upper cylinder 21 is installed on the top support plate 12, the output end of the upper cylinder 21 passes through the top support plate 12 and extends downward, and the end surface is connected to a box cover 22. A cylinder seat 13 is arranged between the two side support plates 11, a push-pull cylinder 25 is installed on the cylinder seat 13, the output end of the push-pull cylinder 25 is connected to a push-pull seat 26, and a vacuum box 27 is installed on the side wall of the push-pull seat 26.

[0024] Among them, a sealing ring 28 is arranged on the top wall of the vacuum box 27, a vacuum suction pipe 271 is arranged at the bottom of the vacuum box 27, a workpiece plate 272 is arranged at the bottom of the vacuum box 27, and a movable cutter and a fixed cutter are symmetrically arranged in the horizontal direction inside the workpiece plate 272. A lower cylinder 61 is arranged at the bottom of the vacuum box 27, and the output end of the lower cylinder 61 is connected to a knife seat 63 through a connecting rod 62. The knife seat 63 is arranged in a slope and cooperates with the tail end of the movable cutter.

[0025] The vacuum suction pipe 271 is connected to the vacuum equipment and is used to evacuate the inside of the vacuum box 27. The connecting rod 62 is sheathed with a bellows 62 to ensure good sealing during the movement.

[0026] Among them, a linear bearing 24 is embedded and installed on the top support plate 12, and a guide column 23 is arranged in the linear bearing 24. The guide column 23 is connected to the box cover 22 to ensure that the box cover 22 maintains a stable and accurate positioning during the opening and closing process.

[0027] Among them, the workpiece plate 272 is used to install the workpiece, and a sealing device 51 is installed on the vacuum box 27 below the workpiece plate 272, and the output end of the sealing device 51 is connected to a sealing tube 52. A channel 53 is provided on the workpiece plate 272, and the sealing tube 52 is connected to the channel 53. A helium filling component 29 is connected to the sealing tube 52 to ensure that the gas environment inside the vacuum box remains stable during the processing.

[0028] Among them, a vacuum pressure hoop 71 is provided on the outer wall of the vacuum box 27, a bend pipe joint 72 is provided inside the vacuum pressure hoop 71, a vacuum tube 73 is connected to the end of the bend pipe joint 72, and a vacuum valve 74 is connected to the tail end of the vacuum tube 73 to ensure that the sealing performance of the vacuum box 27 is more reliable.

[0029] Among them, a front fixed seat 41 is installed at the bottom of the vacuum box 27, and a rear positioning seat 43 is installed at the bottom of the side support plate 11. A sliding column 42 is arranged between the front fixed seat 41 and the rear positioning seat 43. The sliding column 42 is fixedly connected to the front fixed seat 41 and is slidably connected to the rear positioning seat 43 to ensure that the vacuum box 27 has better stability and positioning accuracy during the cutting process.

[0030] Among them, guide rails 31 are arranged on both sides of the vacuum box 27, and a positioning slide 32 is slidably connected to the outside of the guide rails 31. The positioning slide 32 is installed on the opposite inner walls of the two side support plates 11 to further improve the cutting accuracy and the convenience of operation.

[0031] Among them, a spring device is arranged between the movable cutter and the fixed cutter, and the spring device is used to provide a stable rebound force during the cutting process to ensure the uniformity of the cutting effect, thereby improving the cutting quality.

[0032] In this embodiment, the workpiece is mounted on the workpiece plate 272, and then the push-pull cylinder 25 is pushed and pulled, and the push-pull cylinder 25 drives the push-pull seat 26 and the vacuum box 27 to move, so that the guide rails 31 on both sides of the vacuum box 27 slide along the positioning slide 32 until the vacuum box 27 is located below the box cover 22, and the upper cylinder 21 is started to make the box cover 22 descend and close the top of the vacuum box 27 to ensure that a sealed environment is formed inside. Next, the lower cylinder 61 is started, and the knife seat 63 is driven through the connecting rod 62, so that the movable cutter contacts the fixed cutter and starts to cut the workpiece.

[0033] At the same time, the vacuum equipment evacuates the interior through the vacuum suction pipe 271 to ensure a vacuum environment. During the cutting process, the vacuum clamp 71 is controlled by the vacuum tube 73 and the vacuum valve 74 to ensure that the interior of the vacuum box 27 maintains a stable negative pressure state. At the same time, due to the effects of the sealing device 51 and the helium filling component 29, the interior of the workpiece is filled with helium and sealed to avoid interference from external gases, thereby ensuring the quality of workpiece processing.

[0034] When the cutting is completed, the vacuum state inside the vacuum box 27 is released through the vacuum valve 74, and the box cover 22 is opened under the action of the upper cylinder 21, so that the cut workpieces can be easily taken out. Due to the arrangement of the guide rail 31 and the positioning slide 32, the operator can easily take the workpieces out of the vacuum box 27 and place and cut the next batch of workpieces.

[0035] During the entire cutting process, the cooperation between the slide column 42 and the front fixed seat 41 and the rear positioning seat 43 ensures the stability and positioning accuracy of the vacuum box 27 during the cutting process. The spring device between the movable cutter and the fixed cutter provides a uniform rebound force, ensuring the uniformity and consistency of the cutting effect, thereby improving the cutting quality.

[0036] The present invention not only improves the quality and efficiency of workpiece processing, but also ensures the stability and accuracy of the cutting process, thereby greatly improving production efficiency and product consistency.
