The pressing column 3041 is fixedly arranged on the bearing seat 3042, and the outer diameter of the pressing column 3041 matches the arc groove 3011. Under the action of the second driving assembly 305, the pressing column 3041 cooperates with the arc groove 3011 on the second forming seat 301 to perform reverse punching on the central wave crest of the wavy insulation component material 5, so that the troughs on both sides of the insulation component material 5 are close to each other and wrapped on the pressing column 3041 to form a cylindrical shape.

The second driving assembly 305 includes a first mounting seat 2051, a motor 2052, a transmission gear 2053, and a first linear motion member 2054.

The second linear moving member 3062, the rubber tube 3061 and the limiting groove 3043 are coaxially arranged so that the rubber tube 3061 forms a sliding fit with the limiting groove 3043. The purpose of this arrangement is to use the second linear moving member 3062 to push the rubber tube 3061 to perform a linear motion in the horizontal direction along the limiting groove 3043, so as to push the cylindrical heat insulating member material 5 sleeved on the pressing column 3041 away from the pressing column 3041.

[0045] In this embodiment, the second limit block 302 is detachably mounted on the second forming seat 301 by a second bolt assembly. Relevant technical personnel in this field should know that the purpose of this setting is to limit the second limit block 302 on the second forming seat 301. Therefore, in some embodiments, the second forming seat 301 can also be detachably mounted on the second forming seat 301 by snap-fitting, or fixedly connected to the second forming seat 301 by welding.

[0046] In this embodiment, further, at least two groups of wave-shaped grooves 2011 are arranged in parallel on the first forming seat 201; at least two groups of arc-shaped grooves 3011 are arranged in parallel on the second forming seat 301.

The purpose of this arrangement is to utilize the third linear motion part 404 to push the arc block 405 to perform linear motion in the vertical direction, so as to cause the arc block 405 and the electromagnet 406 to resist the wavy-shaped insulation component material 5. At this time, the electromagnet 406 is started to adsorb the wavy insulation component 5. At this time, the third linear motion part 404 is reset, and the electric slide 401 is started, so as to cause the electric slide 401 to perform linear motion in the horizontal direction along the guide rod 402, thereby transferring the wavy-shaped insulation component material 5 to the pressure forming mechanism 3, and embedding it into the space formed by the second limit block 302 and the second forming seat 301, so as to realize the transfer of the wavy insulation component material 5 to the pressure forming mechanism 3 to be stamped into a tube.

[0048] In this embodiment, the plate-shaped insulation component material 5 is first overlapped on the wavy groove 2011 and limited by the two first limit blocks 202. At this time, the first linear motion member 2054 is started to push the pressing member 204 to perform linear movement in the vertical direction, and the plate-shaped insulation component 5 is punched to make the plate-shaped insulation component material 5 fit the wavy groove 2011, so that the plate-shaped insulation component material 5 presents a wavy insulation component material 5. At this time, the first linear motion member 2054 causes the pressing member 204 to reset, and the motor 2052 pushes the pressing member 204 through the transmission 2053. The first mounting seat 2051 is driven to rotate at an angle of 90 degrees in the horizontal direction, and the pressing member 204 is moved away from the insulating member material 5.

At this time, the electromagnet 406 is started to absorb the wavy insulating member 5. At this time, the third linear motion member 404 drives the arc block 405 to reset and starts the electric slide 401. The electric slide 401 moves along the guide The rod 402 performs a linear motion in the horizontal direction along the length direction, so that the wavy insulation member 5 adsorbed on the electromagnet 406 is transferred to the second forming seat 301, and the two sides of the wavy insulation member material 5 are embedded in the second limit block 302, and the electric slide 401 and the third linear motion member 404 are reset. At this time, the second driving component 305 is started to drive the bearing seat 3042 to perform a rotational motion of 90 degrees in the horizontal direction, so that the pressure column 3041 is located directly above the second forming seat 301, and the second driving component 305 drives the pressure column 304 1 performs linear motion in the vertical direction, so that the central wave crest of the wavy insulation member material 5 is fitted into the arc groove 3011.

[0049] Furthermore, for the low-temperature vacuum pump insulation component processed by the above-mentioned low-temperature vacuum pump insulation component processing device, after the insulation component material 5 is pushed out from the pressure column 3041, an insulation layer that fits the inner wall of the cylinder of the insulation component material 5 is embedded and installed, and the thickness of the insulation layer is greater than the thickness of the insulation component. The material of the insulation layer is foamed resin or foamed polystyrene, thereby obtaining an insulation component.

[0051] Pressure sensors are respectively installed at the bottom of the first forming seat 201 and the bottom of the second forming seat 301. Firstly, a forming quality evaluation model is constructed by obtaining the first punching speed information, the first punching pressure information, the second punching speed information and the second punching pressure information. The expression of the forming quality evaluation model is: ; ; ; Among them, C(V D ,F D ,V C ,F C ) is the molding quality coefficient, M is the weight of the insulation component material 5, C D (V D ,F D ) is the pressure setting coefficient, μ is the molding quality influencing factor, F C1 is the average of the upper and lower limits of the second punching pressure threshold, V C1 is the average of the upper and lower limits of the second punching speed threshold, F C2 is the lower limit of the second punching pressure threshold, V C2 is the lower limit of the second punching speed threshold, α is the influencing factor of the first punching speed, β is the influencing factor of the first punching pressure, α and β were subjected to multiple data analysis using SPSS software, and the final values ​​were: 0≤ α ≤0.85, 0≤ β ≤0.94.

[0052] Then, the molding quality coefficient is output according to the molding quality evaluation model to evaluate the molding quality of the insulation component, and the first stamping speed information, first stamping pressure information, second stamping speed information and second stamping pressure information of the subsequent insulation component are adjusted according to the evaluation result, so that the molding quality coefficient is within the coefficient threshold, so as to improve and monitor the molding quality of the insulation component.

[0053] Specifically, a method for processing an insulation component using the above-mentioned low-temperature vacuum pump insulation component processing device comprises the following steps: S1, overlap the plate-shaped insulation component material 5 on the wavy groove 2011 and limit it through two first limit blocks 202, start the first linear motion member 2054 to push the pressing member 204 to perform linear motion in the vertical direction, and press the plate-shaped insulation component material 5 to make the plate-shaped insulation component 5 fit the wavy groove 2011. At this time, the plate-shaped insulation component material 5 presents a wavy insulation component material 5; S2, the first linear motion member 2054 causes the pressing member 204 to reset, and the motor 2052 is started. After the motor 2052 pushes the first mounting seat 2051 to rotate at an angle of ninety degrees in the horizontal direction through the transmission gear 2053, the third linear motion member 404 pushes the arc block 405 and the electromagnet 406 to perform linear motion in the vertical direction, so that the arc block 405 and the electromagnet 406 resist the wavy insulation member 5, and the electromagnet 406 is started to adsorb the wavy insulation member 5. Then, the third linear motion member 404 drives the arc block 405 to reset and starts the electric slide 401. The electric slide 401 performs linear motion in the horizontal direction along the length direction of the guide rod 402, so that the wavy insulation member 5 adsorbed on the electromagnet 406 is transported to the second forming seat 301, and the two sides of the wavy insulation member material 5 are embedded in the space formed by the second limit block 302 and the second forming seat 301. S3, the electric slide 401 and the third linear motion member 404 are reset, and the second driving assembly 305 is started to drive the bearing seat 3042 to rotate at a 90-degree angle in the horizontal direction, so that the pressing column 3041 is located directly above the central wave crest of the wavy insulation member material 5. At this time, the second driving assembly 305 drives the pressing column 3041 to perform linear motion in the vertical direction, so that the central wave crest of the wavy insulation member 5 is reversely attached to the arc groove 3011. At this time, the two sides of the wavy insulation component material 5 are close together and wrapped around the pressing column 3041 in a cylindrical shape. Then, the second driving assembly 305 drives the cylindrical insulation component material 5 away from the second forming seat 301, and the second linear moving member 3062 pushes the rubber tube 3061 to perform linear motion in the horizontal direction along the limiting groove 3043, so as to push the cylindrical insulation component material 5 sleeved on the pressing column 3041 away from the pressing column 3041, thereby completing the stamping of the insulation component material 5 into a cylinder. S4, obtaining the first punching speed information V of the pressing member 204 on the plate-shaped insulation member material 5 D And the first punching pressure information F D , obtain the second punching speed information V of the pressing column 3041 on the wavy insulation component material 5 C And the second punching pressure information F C, the first punching speed information, the first punching pressure information, the second punching speed information and the second punching pressure information are compared with the set first speed threshold, the first punching pressure threshold, the second punching pressure threshold and the second punching pressure threshold, and the V D 、F D 、V C 、F C The values ​​fall within the first stamping speed threshold, the first stamping pressure threshold, the second stamping speed threshold, and the second stamping pressure threshold, respectively; for example, if the first stamping speed information exceeds the first stamping speed threshold, the pushing speed of the first linear motion member 2054 on the pressing member 204 is adjusted, so that the first stamping speed information of the pressing member 204 on the plate-like thermal insulation member 5 next time is within the first stamping speed threshold; if the first stamping pressure information is not within the first stamping pressure threshold, the first linear motion member 2054 is adjusted, so that the first stamping pressure information of the pressing member 204 on the plate-like thermal insulation member 5 next time is within the first stamping pressure threshold; S5. On the basis that the first punching speed information, the first punching pressure information, the second punching speed information and the second punching pressure information are within the corresponding thresholds, the four are dimensionlessly processed and then imported into the forming quality assessment model to output the forming quality coefficient. The expression of the forming quality assessment model is: ; ; ; Among them, C(V D ,F D ,V C ,F C ) is the molding quality coefficient, M is the weight of the insulation component material 5, C D (V D ,F D ) is the pressure setting coefficient, μ is the molding quality influencing factor, F C1 is the average of the upper and lower limits of the second punching pressure threshold, V C1 is the average of the upper and lower limits of the second punching speed threshold, F C2 is the lower limit of the second punching pressure threshold, V C2 is the lower limit of the second punching speed threshold, α is the influence factor of the first punching speed, 0≤ α ≤0.85, β is the influence factor of the first punching pressure, 0≤ β ≤0.94; S6. Compare the obtained molding quality coefficient with the preset coefficient threshold. If the output molding quality coefficient is within the preset coefficient threshold, the current V D 、F D 、VC 、F C ; If the output molding quality coefficient is not within the preset coefficient threshold, V D 、F D 、V C 、F C Adjustments are made until the output molding quality coefficient is within the preset coefficient threshold.
