Description

Technical Field

[0001] This utility model relates to the field of nuclear industry technology, and in particular to a feeding and pressing device for nuclear industry material plates. Background Technology

[0002] Nuclear energy, as a clean and efficient energy source, is widely used in power generation, medical treatment, scientific research, and other fields. However, nuclear energy equipment, especially nuclear fuel plates, is usually plate-shaped. In order to ensure its performance during experimental research and industrial processing, vapor deposition technology (physical vapor deposition, PVD) is usually used to coat and evaporate the fuel plates. The purpose is to remove moisture and enhance the adhesion between the film and the substrate. Heating the substrate under high vacuum can desorb the gas adsorbed on the surface of the substrate.

[0003] If the film thickness on the product to be coated is inconsistent or uneven, it will affect the quality of the product, thereby increasing the process cost. Furthermore, in existing physical vapor deposition operations, if the material plate does not fully contact the heating element, the performance of the film deposited on the target workpiece will be poor, thus reducing the processing quality of the target workpiece.

[0004] During the heating reaction, the material plate is relatively soft and easily deforms when in contact with the heating element, making it difficult to adhere. During the heating reaction, the heating of the nuclear material plate can easily generate harmful substances, which are inconvenient for workers to handle. At the same time, if the material plate cannot be effectively adhered to the heating element to achieve all-round heating, local heating of the material plate will occur. When the local temperature is too high, production accidents will occur, and the conditions for subsequent processing will also be affected. Therefore, we propose a pressing and lifting device for nuclear industry material plates.

[0005] A plywood gluing apparatus disclosed in Russian patent document RU128152U1 includes upper and lower heating plates and a device for forming an embossed pattern on the front surface of the furnace. This device is made in the form of a lining with through-holes forming the desired embossed pattern, installed before gluing to the laminated material assembly. The claimed utility model reduces process complexity due to the quick installation and replacement of the device for forming the embossed pattern on the front surface of the plywood, and the presence of the curled seams-lining, which are straight-through, helps remove the vapor-gas mixture formed during veneer gluing. However, the plywood gluing apparatus lacks a lifting device, resulting in insufficient contact between the plywood and the heating mechanism, potentially causing localized overheating.

[0006] To address the shortcomings of the existing technology, providing a feeding and pressing device for nuclear industry material plates is a problem worthy of study. Utility Model Content

[0007] The purpose of this invention is to overcome the disadvantages of nuclear material plates, which are prone to generating harmful substances when heated and are inconvenient for workers to handle. It provides a feeding and pressing device for nuclear material plates, which achieves the technical effect of mechanically assisting in the complete bonding of nuclear material plates and heating plates.

[0008] The objective of this utility model is achieved through the following technical solution:

[0009] A feeding and pressing device for nuclear industry material plates includes a protective shell, several heating elements fixedly connected to the inner top wall of the protective shell, several receiving devices disposed on the inner bottom surface of the protective shell, and a fixing frame disposed inside the protective shell. It also includes lifting and pressing mechanisms disposed on both sides of the protective shell, tooling disposed above the lifting and pressing mechanisms, and a conveying mechanism disposed below the tooling.

[0010] Tensioning grooves are provided at all four corners of the assembly slot of the tooling. Bolts are threaded to one side of the inner wall of the tensioning groove. One end of the bolt is located outside the tensioning groove, and the other end of the bolt is rotatably connected to a tensioning block. Both the tensioning block and the tensioning groove are trapezoidal. The shape of the tensioning block is adapted to the shape of the tensioning groove. The tooling clamps and assembles a nuclear industry material plate through the tensioning block. The nuclear industry material plate can maintain a stable state during the tightening, lifting and heating process.

[0011] The conveying mechanism includes a main rotating shaft rotatably connected inside the protective housing, several conveying wheels rotatably connected to both sides inside the protective housing, a first motor disposed outside the protective housing, a secondary rotating shaft driven by the first motor, and a universal joint disposed between the main rotating shaft and the secondary rotating shaft.

[0012] The main rotating shaft and the conveyor wheel are respectively equipped with sprockets, and the sprockets of the main rotating shaft and the conveyor wheel are equipped with transmission chains. The main rotating shaft and the conveyor wheel are connected by transmission chains through sprockets and transmission chains. Nuclear industry material plates can be automatically fed, reducing manual input and avoiding injury to personnel when nuclear industry material plates are heated.

[0013] The lifting and pressing mechanism includes a second motor fixedly connected to the protective housing, a gear set fixedly connected to the output end of the second motor, a lifting frame meshing with the gear set, a first lifting plate fixedly connected to the bottom of the lifting frame, and a plurality of first springs fixedly connected to the top of the first lifting plate.

[0014] The inner side of the first lifting plate is located below the tooling, and the first spring is disposed between the tooling and the first lifting plate, so that the nuclear industry material plate can automatically rise and fall when heated, and make contact with the heating body to achieve full heating, thus avoiding the situation where the nuclear industry material plate will cause injury to personnel when heated.

[0015] The inner walls of the protective shell are equipped with protective baffles on both sides. The protective baffles are located on both sides of the lifting frame to improve its lifting stability and to protect the gear set inside the lifting frame.

[0016] The lifting and pressing mechanism includes a second lifting plate that is vertically slidably connected to both sides of the fixed frame, a lifting shaft that is horizontally rotatably connected to both sides of the fixed frame, and several lead screws that are vertically rotatably connected to both sides of the fixed frame.

[0017] Several first bevel gears are fixedly connected to the lifting shaft, and second bevel gears are fixedly connected to the bottom of the lead screw.

[0018] The lifting shaft is located below the second lifting plate. The number of the first bevel gear and the second bevel gear are equal and their positions correspond one-to-one. The first bevel gear and the second bevel gear are perpendicular to each other and mesh. The lead screw is threadedly connected to the second lifting plate. The lifting shaft is driven by a servo motor, which converts the rotational torque of the lead screw into the lifting force of the second lifting plate to control the lifting of the second lifting plate. The inner side of the second lifting plate is located below the tooling, which drives the tooling to rise and make full contact with the heating element, thus completing the lifting and heating treatment of the tooling and the nuclear industry material plate.

[0019] Several second springs are fixedly connected to the inner side of the top of the second lifting plate, and the second springs are located below the tooling.

[0020] Positive and beneficial effects:

[0021] 1. The nuclear industrial material plate uses a feeding and pressing device. The lifting plate drives the nuclear industrial material plate to rise and make full contact with the heating body. This allows the nuclear industrial material plate to automatically rise and fall during heating, ensuring full heating and preventing injury to personnel during heating.

[0022] 2. The nuclear industry material plate feeding and pressing device uses a universal joint to enable transmission between the two, thereby rotating the main rotating shaft. The sprocket on the main rotating shaft drives the conveyor wheel below the material plate to rotate, feeding and transferring the tooling and nuclear industry material plate placed on the conveyor wheel. This allows the nuclear industry material plate to be automatically fed, reducing manual input and avoiding injury to personnel when the nuclear industry material plate is heated.

[0023] 3. The nuclear industry material plate is fed and pressed by a tensioning block to clamp and fix the nuclear industry material plate, so that the nuclear industry material plate can maintain a stable state during the tightening, lifting and heating process. Attached Figure Description

Detailed Implementation

[0034] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0035] Example 1

[0036] like Figures 1 to 9As shown, the feeding and pressing device for nuclear industry material plates includes a protective shell 1, a plurality of heating elements 2 fixedly connected to the inner top wall of the protective shell 1, a plurality of receiving devices 3 disposed on the inner bottom surface of the protective shell 1, and a fixing frame disposed inside the protective shell 1. It also includes lifting and pressing mechanisms 5 disposed on both sides of the protective shell 1, tooling 6 disposed above the lifting and pressing mechanisms 5, and a conveying mechanism 7 disposed below the tooling 6.

[0037] like Figures 3 to 4 As shown, tensioning grooves 10 are provided at the four corners of the assembly slot of the tooling 6. Bolts 11 are threadedly connected to one side of the inner wall of the tensioning groove 10. One end of the bolt 11 is located on the outside of the tensioning groove 10, and the other end of the bolt 11 is rotatably connected to a tensioning block 8. Both the tensioning block 8 and the tensioning groove 10 are trapezoidal. The shape of the tensioning block 8 is adapted to the shape of the tensioning groove 10. The tooling 6 clamps and assembles the nuclear industry material plate 9 through the tensioning block 8. After the nuclear industry material plate 9 is placed in the groove of the tooling 6 by setting the tensioning block 8 on the tooling 6, the bolt on the tensioning block 8 is rotated to move the tensioning block 8 to clamp and fix the nuclear industry material plate 9, so that the nuclear industry material plate 9 can maintain a stable state during the tightening, lifting and heating process.

[0038] like Figures 3 to 5 As shown, the conveying mechanism 7 includes a main rotating shaft 701 rotatably connected inside the protective housing 1, a plurality of conveying wheels 702 rotatably connected to both sides inside the protective housing 1, a first motor 703 disposed outside the protective housing 1, a secondary rotating shaft 704 drivenly connected to the first motor 703, and a universal shaft 705 disposed between the main rotating shaft 701 and the secondary rotating shaft 704.

[0039] like Figures 3 to 5 As shown, sprockets are respectively installed on the main rotating shaft 701 and the conveyor wheel 702. A transmission chain is installed on the sprockets of the main rotating shaft 701 and the conveyor wheel 702. The main rotating shaft 701 and the conveyor wheel 702 are connected by the sprockets and the transmission chain. A first motor 703 is installed outside the protective housing 1, which drives the auxiliary rotating shaft 704 to rotate. Since there is an included angle between the main rotating shaft 701 and the auxiliary rotating shaft 704, the universal joint 705 enables them to transmit power, thereby making the main rotating shaft 701 rotate. The sprocket on the main rotating shaft 701 and the sprocket on the conveyor wheel 702 below the material plate rotate through the chain drive, which feeds and transmits the tooling 6 and the nuclear industry material plate 9 placed on the conveyor wheel 702, so that the nuclear industry material plate 9 can be automatically fed, reducing manual input and avoiding injury to personnel when the nuclear industry material plate 9 is heated.

[0040] like Figures 1 to 5As shown, the lifting and pressing mechanism 5 includes a second motor 501 fixedly connected to the protective housing 1, a gear set 502 fixedly connected to the output end of the second motor 501, a lifting frame 503 meshing with the gear set 502, a first lifting plate 504 fixedly connected to the bottom of the lifting frame 503, and a plurality of first springs 505 fixedly connected to the top of the first lifting plate 504.

[0041] like Figures 1 to 5 As shown, the inner side of the first lifting plate 504 is located below the tooling 6. The first spring 505 is disposed between the tooling 6 and the first lifting plate 504. A second motor 501, a gear set 502, and a lifting frame 503 are disposed on the protective housing 1. The second motor 501 drives the gear set 502 to rotate, and the meshing relationship between the gear set 502 and the lifting frame 503 drives the lifting frame 503 and the first lifting plate 504 to rise and fall, thereby driving the tooling 6 and the nuclear industry material plate 9 above the first lifting plate 504 to rise and fall. When the nuclear industry material plate needs to be heated, the first lifting plate 504 drives the nuclear industry material plate to rise and fully contact the heating body 2, so that the nuclear industry material plate 9 can automatically rise and fall when heated, and fully heat the material plate 9 by contacting the heating body 2, thus avoiding the situation where the nuclear industry material plate 9 will cause injury to personnel when heated.

[0042] Furthermore, a first spring 505 is provided above the first lifting plate 504. After the nuclear industrial material plate 9 contacts the heating body 2, the first lifting plate 504 continues to rise, causing the first spring 505 to compress, increasing the pressure between the nuclear industrial material plate 9 and the heating body 2, so that the two can make full contact for heating. The extension and retraction of the first spring 505 can increase the fault tolerance of the material plate lifting, avoiding the situation where the nuclear industrial material plate 9 fails to make contact or is too tightly fitted during the lifting process, which affects the heating effect.

[0043] like Figure 5 As shown, protective baffles 506 are provided on both sides of the inner wall of the protective housing 1. The protective baffles 506 are located on both sides of the lifting frame 503. By providing protective baffles 506 on both sides of the lifting frame 503, the lifting and lowering of the lifting frame 503 and the first lifting plate 504 are limited, thereby improving the stability of its lifting and lowering, and also providing protection for the gear set 502 inside the lifting frame 503.

[0044] Example 2

[0045] like Figures 6 to 9 As shown, the lifting and pressing mechanism 5 includes a second lifting plate 511 vertically slidably connected to both sides of the fixed frame, a lifting shaft 512 horizontally rotatably connected to both sides of the fixed frame, and a plurality of lead screws 514 vertically rotatably connected to both sides of the fixed frame.

[0046] Several first bevel gears 513 are fixedly connected to the lifting shaft 512, and second bevel gears 515 are fixedly connected to the bottom of the lead screw 514.

[0047] like Figures 7 to 9 As shown, the lifting shaft 512 is located below the second lifting plate 511. The number of first bevel gears 513 and second bevel gears 515 is equal and their positions correspond one-to-one. The first bevel gears 513 and second bevel gears 515 are perpendicular to each other and mesh. The lead screw 514 is threadedly connected to the second lifting plate 511. The lifting shaft 512 is driven by a servo motor. By setting the first bevel gears 513 and second bevel gears 515 that are mutually engaged between the lifting shaft 512 and the lead screw 514, when the servo motor drives the lifting shaft 512 to rotate, the lead screw 514 will rotate accordingly under the transmission action of the first bevel gears 513 and second bevel gears 515. The lead screw 514 is threadedly connected to the second lifting plate 511, so that the rotational torque of the lead screw 514 is converted into the lifting force of the second lifting plate 511 to control the lifting of the second lifting plate 511. The inner side of the second lifting plate 511 is located below the tooling 6, which drives the tooling 6 to rise and fully contact the heating body 2 to complete the lifting and heating treatment of the tooling 6 and the nuclear industry material plate 9.

[0048] like Figures 7 to 9 As shown, several second springs 516 are fixedly connected to the inner side of the top of the second lifting plate 511. The second springs 516 are located below the tooling 6. The second springs 516 buffer the lifting and lowering of the tooling 6 and the nuclear industry material plate 9, so as to avoid the nuclear industry material plate 9 from being damaged by collision with the heating body 2 during the rising process.

[0049] The working principle of this utility model is as follows:

[0050] S1. After placing the nuclear industry material plate 9 into the groove of the tooling 6, rotate the bolt on the tensioning block 8 to move the tensioning block 8 to clamp and fix the nuclear industry material plate 9, so that the nuclear industry material plate 9 can maintain a stable state during the tightening, lifting and heating process.

[0051] S2. The universal joint 705 enables the two to drive each other, thereby rotating the main rotating shaft 701. The sprocket on the main rotating shaft 701 drives the conveyor wheel 702 below the material plate to rotate, feeding and conveying the tooling 6 and the nuclear industry material plate 9 placed on the conveyor wheel 702, so that the nuclear industry material plate 9 can be automatically fed, reducing manual input and avoiding injury to personnel when the nuclear industry material plate 9 is heated.

[0052] S3. The second motor 501 drives the gear set 502 to rotate, and the meshing relationship between the gear set 502 and the lifting frame 503 drives the lifting frame 503 and the first lifting plate 504 to rise and fall, thereby driving the tooling 6 and the nuclear industry material plate 9 above the first lifting plate 504 to rise and fall.

[0053] S4. When the servo motor drives the lifting shaft 512 to rotate, the lead screw 514 rotates under the transmission action of the first bevel gear 513 and the second bevel gear 515. The lead screw 514 is threadedly connected to the second lifting plate 511, so the rotational torque of the lead screw 514 is converted into the lifting force of the second lifting plate 511 to control the lifting of the second lifting plate 511. The inner side of the second lifting plate 511 is located below the tooling 6, which drives the tooling 6 to rise and fully contact the heating body 2.

[0054] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
