Abstract
Description
Technical Field
[0001] This utility model relates to the field of thermal insulation door technology, and in particular to a thermal insulation door for thermoforming equipment. Background Technology
[0002] Thermoforming is currently one of the main processing technologies for titanium alloy sheet metal forming. The thermal insulation performance of thermoforming equipment is a major factor affecting processing efficiency. However, the thermal insulation doors of thermoforming equipment need to be opened and closed frequently due to the handling of parts, making the opening and closing of these doors a primary cause of heat dissipation.
[0003] Currently, the insulated doors of thermoforming equipment all use one-piece door panels, which need to be opened or closed as a whole during the opening and closing process. Due to the large overall height of the one-piece door panel, the stroke during opening and closing is large, resulting in significant heat loss from the thermoforming equipment during the opening and closing of the insulated door, which affects processing efficiency. Utility Model Content
[0004] The purpose of this utility model is to address the deficiencies in the above-mentioned technology by providing a heat-insulating door for thermoforming equipment. The door adopts a combination of a first door body and a second door body, and each door body can move independently, reducing the opening and closing stroke, thereby reducing heat loss and improving work efficiency.
[0005] The purpose of this utility model is achieved as follows: it includes a door frame, which is used to connect a thermoforming device;
[0006] The door frame is slidably connected to the first door body and the second door body, and the first door body and the second door body are arranged along the height direction of the door frame;
[0007] It also includes a drive mechanism for driving the first door body and the second door body to slide independently along the door frame.
[0008] In the above solution, the insulated door adopts a combination of the first door body and the second door body, and the first door body and the second door body are driven to move independently through a drive mechanism. During the opening and closing of the insulated door, the first door body and the second door body move independently. Since the height of the first door body and the second door body is less than the height of the original one-piece door panel, the movement stroke of the first door body and the second door body is reduced, thereby shortening the opening and closing time, reducing the heat loss of the thermoforming equipment, and improving work efficiency.
[0009] In some possible implementations, the first door and the second door are provided with thermal insulation structures.
[0010] In some possible implementations, the first door and the second door are provided with heating tubes, which pass through the first door and the second door from the side away from the thermoforming equipment and are arranged on the side of the first door and the second door closer to the thermoforming equipment.
[0011] In some possible implementations, the contact surfaces of the first door body and the second door body are provided with interlocking strip-shaped protrusions and strip-shaped grooves;
[0012] The strip-shaped protrusions and the strip-shaped grooves are respectively disposed on the first door body and the second door body.
[0013] In some possible implementations, a slide rail is provided on each side of the door frame, and the first door body and the second door body are slidably connected to the slide rail via a sliding sleeve.
[0014] In some possible implementations, the sliding sleeve is provided with a connecting lug on the side away from the first door body and the second door body;
[0015] The connecting ear is connected to the driving mechanism.
[0016] In some possible implementations, the drive mechanism is a telescopic rod, one end of which is hinged to the door frame and the other end of which is hinged to the connecting lug.
[0017] In some possible implementations, the lower part of the door frame is provided with a support base. Attached Figure Description

[0022] This application provides an insulated door for thermoforming equipment. The insulated door adopts a combination of a first door body and a second door body, and the first and second door bodies are driven independently by a drive mechanism. During the opening and closing of the insulated door, the first and second door bodies move independently. Since the height of the first and second door bodies is smaller than that of the original one-piece door panel, the travel distance of the first and second door bodies is reduced, thereby shortening the opening and closing time, reducing heat loss of the thermoforming equipment, and improving work efficiency. This solves the problems of large travel distance, long opening and closing time, and large heat loss in existing insulated doors.
[0023] To facilitate understanding of the technical solution of this application, its application scenario is described below: The insulated door of the thermoforming equipment in this application is mainly used in titanium alloy thermoforming equipment. The insulated door is installed in the thermoforming equipment and is used for opening and closing to realize the loading and unloading of parts between the thermoforming equipment.
[0024] The following description, in conjunction with the accompanying drawings, further illustrates this implementation case:
[0025] Depend on Figure 1 — Figure 4 As can be seen, this application provides a thermoforming equipment insulation door, including a door frame 1, which is used to connect the thermoforming equipment 200. It should be understood that the connection between the door frame 1 and the thermoforming equipment 200 can be a fixed connection, such as welding; or it can be a detachable connection, such as a connection achieved through bolts or other components.
[0026] The insulated door 100 of this application is a split type, including a first door body 2 and a second door body 3. In order to realize the opening and closing between the first door body 2 and the second door body 3, the door frame 1 of this application is slidably connected to the first door body 2 and the second door body 3, and the first door body 2 and the second door body 3 are arranged along the height direction of the door frame 1.
[0027] Reference Figure 1 , Figure 1 The first door 2 and the second door 3 are in the closed state. When the first door 2 and the second door 3 are closed, the thermoforming equipment 200 presses the part inside the thermoforming chamber using a mold. (Refer to...) Figure 2 , Figure 2 The first door 2 and the second door 3 are in the open state, at which time parts can be taken out and placed in the thermoforming chamber of the thermoforming equipment 200. Since the insulated door 100 of this application adopts a split first door 2 and second door 3, the height of the first door 2 and the second door 3 is less than the height of the original door. The first door 2 and the second door 3 move independently. Therefore, during the opening and closing process of the insulated door 100, the travel of the first door 2 and the second door 3 is less than the travel of the original door. This shortens the opening and closing time of the insulated door 100 and reduces heat loss.
[0028] As an example, the sliding connection between the door frame 1 and the first door body 2 and the second door body 3 in this application can be achieved through structures such as dovetail grooves and slide rails 11.
[0029] In order to enable the independent movement of the first door body 2 and the second door body 3, this application also includes a driving mechanism, which is used to drive the first door body 2 and the second door body 3 to slide independently along the door frame 1.
[0030] In this embodiment, the drive mechanism can have various structures, such as electric push rod, pneumatic push rod, hydraulic push rod, motor chain drive mechanism, etc.
[0031] It should be understood that, in order to improve the thermal insulation performance, the thermal insulation door 100 and the thermoforming equipment 200 in this application can be directly equipped with a sealing structure, and the sealing structure can use a high-temperature sealing strip, such as ceramic fiber tape.
[0032] In the above scheme, the heat-insulating door 100 adopts a combination of the first door body 2 and the second door body 3, and the first door body 2 and the second door body 3 are driven to move independently by the drive mechanism. During the opening and closing of the heat-insulating door 100, the first door body 2 and the second door body 3 move independently. Since the height of the first door body 2 and the second door body 3 is less than the height of the original integrated door panel, the movement stroke of the first door body 2 and the second door body 3 is reduced, thereby shortening the opening and closing time, reducing the heat loss of the thermoforming equipment 200, and improving work efficiency.
[0033] Reference Figure 4 , Figure 4 This is a schematic diagram showing the insulated door 100 connected to the thermoforming equipment 200. When the insulated door 100 is opened to pick up or put down parts, the second door body 3 can slide away from the first door body 2 until the top of the second door body 3 is aligned with the lower mold surface 300 of the thermoforming equipment 200. The first door body 2 slides away from the second door body 3 a certain distance, allowing parts to be picked up or put down. Compared to the existing one-piece insulated door 100, this effectively shortens the opening and closing stroke and improves the working cycle.
[0034] In some possible implementations, to enhance thermal insulation performance and reduce heat loss, the first door body 2 and the second door body 3 in this application are provided with thermal insulation structures. As an example, the thermal insulation structure can be achieved by filling the first door body 2 and the second door body 3 with a mixture of zirconium oxide and cement, as well as insulating rock wool and other materials. Since zirconium oxide has a melting point of 2715℃, it imparts excellent high-temperature stability to the mixture, thereby improving its service life while ensuring thermal insulation performance.
[0035] In some possible implementations, refer to Figure 1 , Figure 2The first door body 2 and the second door body 3 are provided with heating tubes 4. The heating tubes 4 pass through the first door body 2 and the second door body 3 from the side away from the thermoforming equipment 200, and are arranged on the side of the first door body 2 and the second door body 3 close to the thermoforming equipment 200.
[0036] Frequent opening and closing of the door leads to significant heat loss at the insulated door 100, easily creating a low-temperature zone and affecting processing efficiency. This application installs a heating pipe 4 at the insulated door 100 to provide auxiliary heating, compensating for heat loss during opening and closing and improving work efficiency.
[0037] As an example, the heating tube 4 in this application can be an electric heating tube 4, that is, a resistance wire is set inside the heating tube 4, and the resistance wire heats up after being energized.
[0038] Reference Figure 3 , Figure 3 This is a partial cross-sectional view of the insulated door 100 of this application. To improve the thermal insulation performance at the junction of the first door body 2 and the second door body 3, the contact surfaces of the first door body 2 and the second door body 3 are provided with interlocking strip-shaped protrusions 21 and strip-shaped grooves 31. Furthermore, the strip-shaped protrusions 21 and the strip-shaped grooves 31 are respectively disposed on the first door body 2 and the second door body 3. When the first door body 2 and the second door body 3 are closed, the strip-shaped protrusions 21 are embedded in the strip-shaped grooves 31, which effectively reduces heat loss compared to a planar contact surface.
[0039] In some possible implementations, refer to Figure 1 , Figure 2 In order to achieve a sliding connection between the door frame 1 and the first door body 2 and the second door body 3, a slide rail 11 is provided on each side of the door frame 1, and the first door body 2 and the second door body 3 are slidably connected to the slide rail 11 through a sliding sleeve 12.
[0040] When the drive mechanism is working, the first door body 2 and the second door body 3 slide along the sliding sleeve 12. As an example, in this application, the slide rail 11 can be made of a first square tube, and the inner diameter of the sliding sleeve 12 can be a second square tube with a diameter slightly larger than the outer diameter of the slide rail 11. The sliding is achieved by connecting the first square tube and the second square tube. If it is necessary to improve the smoothness of sliding, a ball bearing guide rail can also be used as the slide rail 11, and a ball bearing slider can be used as the sliding sleeve 12.
[0041] In some possible implementations, the sliding sleeve 12 has a connecting lug 121 on the side away from the first door body 2 and the second door body 3, and the connecting lug 121 is connected to the driving mechanism. The driving mechanism is a telescopic rod 5, one end of which is hinged to the door frame 1, and the other end is hinged to the connecting lug 121.
[0042] As an example, the connecting ear 121 can be made of two plates welded at a certain distance on one side of the sliding sleeve 12, and the telescopic rod 5 is a hydraulically driven or pneumatically driven telescopic rod 5, which is placed between the two plates and hinged to the two plates.
[0043] In some possible implementations, the lower part of the door frame 1 is provided with a support base 6. As an example, the door frame 1 can be fixed to the thermoforming equipment 200 by means of bolts or other components after being connected to the support base 6.
