Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of pipe processing equipment, specifically a manual safety pipe cutting machine. Background Technology
[0002] Cutting machines are mainly divided into two categories: automatic cutting machines and manual cutting machines. Using a cutting machine generates a large amount of dust. For direct use in a workshop, this is not only environmentally unfriendly but also seriously endangers the health and safety of operators. To address this problem, the applicant's proposed solution is to place the cutting machine in a closed enclosure for operation.
[0003] However, when it comes to the pipe cutting process, if an automatic cutting machine is used, if a jam occurs, the operator cannot detect it in time, and the pipe to be cut is still entering the machine. This may lead to a serious jam. Furthermore, since the automatic cutting machine is located inside the machine, the machine needs to be disassembled every time a jam occurs and maintenance is required. This is not only inconvenient and affects work efficiency, but may also result in a large number of defective products.
[0004] In contrast, using a manual pipe cutter can effectively avoid the problems associated with automatic pipe cutters. However, since the operator needs to hold the handle of a manual cutter to control the cutting action, the health and safety of the operator due to dust cannot be avoided. Therefore, ensuring the safe use of a manual pipe cutter is a problem that we need to further consider and solve. Utility Model Content
[0005] To address the technical problems mentioned above, this utility model provides a manual safety pipe cutting machine.
[0006] The technical solution of this utility model is as follows:
[0007] A manual safety pipe cutting machine includes a housing and a cutting machine body inside. The housing has a material inlet and outlet channel, and a control lever is connected to the handle of the cutting machine body. A strip-shaped notch is opened on one side of the housing, through which the control lever passes. With the above structural design, during use, the operator can control the operation of the control lever by holding it from outside the housing and moving it along the notch, thereby controlling the cutting machine body to perform cutting actions inside the housing. This design can reduce the operator's chance of direct contact with dust.
[0008] As the core technical concept of this utility model, a dustproof device is also provided at the notch. The dustproof device includes two dustproof strips. The outer sides of the two dustproof strips are connected to the two sides of the notch respectively, and the inner sides overlap at the notch. This design utilizes the flexibility of the dustproof strips. When the control lever moves, the dustproof strips can quickly cover the position where the control lever passes, effectively preventing dust from escaping from the notch, ensuring the sealing of the notch, and providing more comprehensive protection for the operator from the harm of dust. It is both environmentally friendly and safe.
[0009] It should be noted that the main body of the cutting machine mentioned above is a manual cutting machine using existing technology, and its specific structure and principle will not be elaborated on here.
[0010] To improve the sealing performance of the dustproof flexible strip, the following further implementation methods are proposed:
[0011] The width of the overlapping part of the two dustproof strips is not less than 1 / 2 of the notch width, so as to reduce the gap between the dustproof strip and the operating handle, improve the sealing performance, prevent dust from escaping from the notch, and protect the operator from the influence of dust.
[0012] Both dustproof strips are longer than the gap, ensuring that the dustproof strips can fully cover the gap and guarantee the seal at the gap, further preventing dust from escaping.
[0013] Both dustproof strips are made of silicone rubber. Silicone rubber is not only flexible but also has good wear resistance, which improves the ability of the dustproof strips to resist friction from the control lever, allowing the dustproof strips to better adapt to the movement of the control lever and extend their service life.
[0014] Both dustproof strips are 2mm thick. Their appropriate thickness ensures that the dustproof strips are not easily damaged during operation, while maintaining sufficient flexibility to adapt to the movement of the control lever.
[0015] Furthermore:
[0016] The dustproof device also includes two clamping plates, which respectively clamp the outer sides of the two dustproof strips to prevent gaps from forming between the outer sides of the two dustproof strips and the housing, thus preventing dust from escaping.
[0017] Preferably, the thickness of the clamping plate is not less than 1 / 2 of the thickness of the dustproof strip, so that it can effectively clamp the dustproof strip and improve the sealing performance.
[0018] To facilitate the replacement of the dustproof strips, both clamping plates are detachably connected to the housing. This detachable connection design makes maintenance and replacement of the dustproof strips more convenient, improving the maintainability of the equipment.
[0019] The beneficial effects of this utility model of a manual safety pipe cutting machine are that by creating a notch in the housing, the operating handle extends from the notch to the outside of the housing, allowing the operator to operate from outside the housing. This not only reduces the chance of direct contact with dust but also improves operational safety. In addition, a dustproof device is designed at the notch. When the operating lever moves, the dustproof strip can quickly cover the area where the operating lever passes, effectively preventing dust from escaping from the notch and ensuring the sealing of the notch. This provides more comprehensive protection for the operator from the influence of dust, making it both environmentally friendly and safe. Attached Figure Description

[0026] See Figure 1 This embodiment provides a manual safety pipe cutting machine, including a housing 2 and a cutting machine body 1 placed inside. The housing 2 has inlet and outlet channels 21 on the left and right sides, and an openable door on the top. When maintenance is required, the door can be opened to expose the cutting machine body 1. The front of the housing 2 is also provided with a switch door 22. The switch door 22 has transparent glass windows on both sides to facilitate observation of the cutting machine body 1 during operation. A vertical strip-shaped notch 221 is provided in the middle of the switch door 22. A control lever 3 is connected to the handle of the cutting machine body 1 and is set through the notch 221. During use, the operator holds the control lever 3 at the front of the housing 2 and observes the inside of the housing 2 through the glass windows. At the same time, the operator controls the control lever 3 to move up and down along the notch 221 to control the cutting machine body 1 to perform cutting actions inside the housing 2, thereby avoiding direct contact with dust.
[0027] In this embodiment, a dustproof device 4 is also provided at the notch 221 to prevent dust from escaping from the notch 221.
[0028] Regarding the structure of dustproof device 4, combined with Figure 2 Specifically, the dustproof device 4 includes two dustproof flexible strips 41 and two pressing plates 42. The outer sides of the two dustproof flexible strips 41 are connected to both sides of the notch 221, and the inner sides overlap at the notch 221. Utilizing the flexibility of the dustproof flexible strips 41, when the control lever 3 moves, the dustproof flexible strips 41 can quickly cover the position through which the control lever 3 passes, effectively preventing dust from escaping from the notch 221, ensuring the sealing of the notch 221, and providing more comprehensive protection for the operator from the harm of dust. It is both environmentally friendly and safe. The two pressing plates 42 press the outer sides of the two dustproof flexible strips 41 respectively to prevent gaps from forming between the outer sides of the two dustproof flexible strips 41 and the housing 2, thus preventing dust from escaping.
[0029] Specifically, regarding the structure of the dustproof strip 41:
[0030] The width of the overlapping portion of the two dustproof strips 41 is not less than 1 / 2 of the width of the notch 221, so as to reduce the gap between the dustproof strips 41 and the operating handle, improve the sealing performance, prevent dust from escaping from the notch 221, and protect the operator from the influence of dust.
[0031] The lengths of the two dustproof strips 41 are both greater than the length of the notch 221, so that the dustproof strips 41 can fully cover the notch 221 to ensure the sealing of the notch 221 and further prevent dust from escaping.
[0032] Both dustproof strips 41 are made of silicone rubber. Silicone rubber is not only flexible but also has good wear resistance, which improves the ability of the dustproof strips 41 to resist friction from the control lever 3, so that the dustproof strips 41 can better adapt to the movement of the control lever 3 and extend their service life.
[0033] Both dustproof strips 41 are 2mm thick. Their appropriate thickness ensures that the dustproof strips 41 are not easily damaged during operation, while maintaining sufficient flexibility to adapt to the movement of the control lever 3.
[0034] Specifically, regarding the structure of the dustproof strip 41:
[0035] The thickness of both clamping plates 42 is not less than 1 / 2 the thickness of the dustproof strip 41, so that it can effectively clamp the dustproof strip 41 and improve the sealing performance.
[0036] Both clamping plates 42 are detachably connected to both sides of the notch 221. The detachable connection design makes it easier to maintain and replace the dustproof strip 41, thus improving the maintainability of the equipment.
[0037] like Figure 3As shown, the main body 1 of the cutting machine in this embodiment is a manual cutting machine commonly used for cutting pipes. Of course, other types of cutting machines that can be controlled by manually pressing down and lifting the handle to cut the workpiece can also be used in this embodiment, without any restrictions.
[0038] This utility model discloses a manual safety pipe cutting machine. By creating a notch 221 in the housing 2, the operating handle extends from the notch 221 to the outside of the housing 2, allowing the operator to operate from outside the housing 2. This not only reduces the chance of direct contact with dust but also improves operational safety. At the same time, a dustproof device 4 is designed at the notch 221. When the operating lever 3 moves, the dustproof soft strip 41 can quickly cover the area where the operating lever 3 passes, effectively preventing dust from escaping from the notch 221 and ensuring the sealing performance of the notch 221. This provides more comprehensive protection for the operator from the influence of dust, making it both environmentally friendly and safe.
