Abstract
Description
Technical Field
[0001] This utility model belongs to the field of machine tool protection technology, and in particular relates to a mechanical explosion-type adaptive pressure relief window component for emergency machine tool fire response. Background Technology
[0002] With the development of high-speed cutting and precision machining technologies, the risk of fires caused by electrical faults, lubrication system leaks, and frictional heat from metal debris inside machine tools has increased significantly. To ensure equipment safety and production continuity, machine tool safety protection technology has upgraded from early passive protection to proactive early warning and dynamic response. Currently, the industry has established a safety system centered on temperature monitoring, smoke detection, and automatic fire suppression. Within this system, pressure control—a key element of fire emergency protection—is gradually becoming a focus of technological research and development. Because in the event of a fire, the high-temperature gas within the machine tool's enclosed space expands rapidly, posing a risk of casing rupture, fire spread, or secondary injuries, the reliability of the pressure relief device directly determines the severity of the accident's consequences.
[0003] Currently, a basic mechanical burst-type pressure relief device widely used in small and medium-sized machine tools is designed based on the inherent strength of the metal material to define the burst pressure threshold. When the pressure generated inside the machine tool due to a fire exceeds the shear strength of the metal sheet, the metal sheet will break to form a pressure relief channel. However, this disposable design cannot be reused, which limits its application in situations where cost and protection requirements are not high. Therefore, it is necessary to design a mechanical burst-type adaptive pressure relief window component for machine tool fire emergency response. Utility Model Content
[0004] This utility model provides a mechanically rupture-type adaptive pressure relief window assembly for emergency machine tool fires, aiming to solve the problem that existing mechanically rupture-type pressure relief devices, which release pressure by breaking a metal sheet when overpressure occurs, have a simple structure but cannot meet the needs of repeated use due to their disposable nature.
[0005] This utility model is implemented as follows: a machine tool fire emergency mechanical blasting adaptive pressure relief window assembly includes a frame; a protective cover hinged to the opposite side of the inner wall of the frame, the surface of the frame having multiple mounting holes, and a limit frame fixedly connected to one side of the frame; a reset assembly mounted on the frame, the reset assembly being used to cause the protective cover to automatically reset after pressure relief; and an adjustment assembly mounted on the reset assembly, the adjustment assembly being able to control the pressure required for the rotation of the protective cover by adjusting the components in the reset assembly.
[0006] Preferably, the reset assembly includes two hooks fixedly connected to one side of the frame surface, the two hooks being symmetrically distributed about the cover.
[0007] Preferably, the reset assembly further includes a tension spring sleeved on each of the hooks, wherein the two tension springs are made of the same material and have the same size.
[0008] Preferably, the reset assembly further includes: a mounting plate fixedly connected to the opposite side of the protective cover surface, both mounting plates being rectangular, and the height of each mounting plate being consistent with that of the protective cover.
[0009] Preferably, the adjustment component includes: a groove formed on the surface of each mounting plate, wherein a hook 2 is slidably connected to the inner wall of each groove, and each hook 2 is matched with a corresponding tension spring.
[0010] Preferably, the adjustment assembly further includes: multiple sets of adjustment holes formed on the surface of each mounting plate, each set of adjustment holes having two holes, wherein the inner wall of each set of adjustment holes is slidably connected to a limit post, one side of each set of limit posts is fixedly connected to a fixing plate, and one side of each fixing plate is fixedly connected to a pull ring.
[0011] Preferably, the adjustment assembly further includes: a mounting rod fixedly connected to one side of each of the fixed plates, one end of each mounting rod being fixedly connected to one side of the corresponding hook.
[0012] Preferably, a limiting plate is fixedly connected to one side of the protective cover, and the limiting plate is L-shaped.
[0013] Compared with related technologies, the mechanical blasting adaptive pressure relief window assembly for machine tool fire emergency provided by this utility model has the following beneficial effects: This utility model, by hingedly installing the protective cover on the frame, when the machine tool is overpressurized due to a fire, the pressure will push the protective cover to rotate around the hinge point, causing the pressure relief window to open, allowing high-temperature gas to be discharged, while external cold air enters, forming a pressure relief channel. After the pressure relief is completed, the reset component controls the protective cover to automatically rotate and reseal the window. In addition, the opening pressure threshold of the protective cover can be set by adjusting the component, making the pressure relief response more accurate and able to meet the needs of different working conditions.

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.
[0021] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments. Example
[0022] like Figures 1 to 5 As shown in the first aspect embodiment of this utility model, a machine tool fire emergency mechanical blasting adaptive pressure relief window assembly includes: a frame 1; a protective cover 4 hinged to the opposite side of the inner wall of the frame 1, the surface of the frame 1 having multiple mounting holes 6, and a limit frame 7 fixedly connected to one side of the frame 1; a reset assembly 3 assembled on the frame 1, the reset assembly 3 being used to cause the protective cover 4 to automatically reset after pressure relief; and an adjustment assembly 2 assembled on the reset assembly 3, the adjustment assembly 2 being able to control the pressure required for the rotation of the protective cover 4 by adjusting the components in the reset assembly 3.
[0023] The technical effects achieved by the above embodiments are as follows: by hingedly installing the protective cover 4 on the frame 1, when the machine tool is overpressurized due to a fire, the pressure will push the protective cover 4 to rotate around the hinge point, so that the pressure relief window opens, the high temperature gas can be discharged, and the external cold air enters at the same time, forming a pressure relief channel. After the pressure relief is completed, the reset component 3 controls the protective cover 4 to automatically rotate and reseal the window. In addition, the opening pressure threshold of the protective cover 4 can be set by adjusting the component 2, so that the pressure relief response is more accurate and can meet the needs of different working conditions. Example
[0024] like Figure 4 and Figure 5 As shown, a machine tool fire emergency mechanical blasting adaptive pressure relief window assembly includes all the contents of Embodiment 1. In addition, the reset assembly 3 includes: two hooks 302 fixedly connected to one side of the surface of the frame 1, the two hooks 302 being symmetrically distributed about the protective cover 4. The reset assembly 3 also includes: a tension spring 303 sleeved on each hook 302, the two tension springs 303 being of the same material and size. The reset assembly 3 also includes: a mounting plate 301 fixedly connected to the opposite side of the surface of the protective cover 4, both mounting plates 301 being rectangular, and the height of each mounting plate 301 being the same as that of the protective cover 4.
[0025] The technical effects achieved by the above embodiments are as follows: After the frame 1 is installed on the machine tool through the mounting hole 6, when the machine tool is overpressurized due to a fire, the pressure pushes the protective cover 4 hinged to the frame 1 to rotate around the hinge point, so that the pressure relief window opens, the high temperature gas is discharged and the external cold air is introduced to form a pressure relief channel; after the pressure relief is completed, the reset component 3 pulls the mounting plate 301 fixed on the opposite side of the protective cover 4 by the tension spring 303 fixedly connected to two symmetrically distributed hooks 302 on one side of the surface of the frame 1, causing the protective cover 4 to automatically rotate and reseal the window. Since the tension springs 303 are of the same material and size and the hooks 302 are symmetrically distributed, the reset force is balanced and stable. The rectangular design of the mounting plate 301 provides a stable connection point, so that the protective cover 4 can be accurately reset in multiple pressure relief processes, realizing the reliable reuse and response accuracy of the pressure relief window. Example
[0026] like Figure 1 and Figure 5As shown, a machine tool fire emergency mechanical blasting adaptive pressure relief window assembly includes all the contents of Embodiment 2. In addition, the adjustment assembly 2 includes: a slide groove 202 formed on the surface of each mounting plate 301, and a hook 203 slidably connected to the inner wall of each slide groove 202. Each hook 203 matches a corresponding tension spring 303. The adjustment assembly 2 also includes: multiple sets of adjustment holes 201 formed on the surface of each mounting plate 301. Each set of adjustment holes 201 has two holes. The inner wall of each set of adjustment holes 201 is slidably connected to a limit post 205. One side of each set of limit posts 205 is fixedly connected to a fixing plate 206. One side of each fixing plate 206 is fixedly connected to a pull ring 204. The adjustment assembly 2 also includes: a mounting rod 207 fixedly connected to one side of each fixing plate 206. One end of each mounting rod 207 is fixedly connected to one side of a corresponding hook 203. One side of the cover 4 is fixedly connected to a limit plate 5, which is L-shaped.
[0027] The technical effects achieved by the above embodiments are as follows: When overpressure occurs inside the machine tool due to a fire, the pressure pushes the protective cover 4 hinged to the frame 1 to rotate around the hinge point, causing the pressure relief window to open and release high-temperature gas; after the pressure relief is completed, the reset component 3 automatically functions, wherein the hook 302 fixed to the surface of the frame 1 is connected to the mounting plate 301 on the protective cover 4 through the sleeved tension spring 303, pulling the protective cover 4 to rotate and reseal the window; the adjustment component 2 further optimizes the response, allowing the hook 203 to slide through the slide groove 202 on the mounting plate 301, and adjusting the initial length of the tension spring 303 by adjusting the adjustment hole 201, the limiting post 205, the fixing plate 206, the pull ring 204 and the mounting rod 207 to change its tension, thereby accurately setting the pressure threshold for opening the protective cover 4, while the limiting plate 5 on the protective cover 4 limits the rotation angle to prevent over-opening; this ensures the reusability of the pressure relief window, the adaptive adjustment of the pressure threshold and the accuracy of the pressure relief response, meeting the needs of diverse working conditions.
