Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass tube processing technology, and in particular to a high borosilicate glass tube cutting device. Background Technology
[0002] High borosilicate glass tubes are glass tubes mainly composed of silicon dioxide and boron oxide. They are characterized by high temperature resistance, impact resistance, and good chemical stability, and are commonly used in laboratory instruments, medical devices, lighting equipment, and other fields. During the production process, a long high borosilicate glass tube needs to be cut into segments. During cutting, the high borosilicate glass tube is placed on a support bracket. After determining the cutting length, a laser cutting machine cuts a circle around the surface of the high borosilicate glass tube. Then, a grilling rod is inserted into the high borosilicate glass tube. The grilling rod consists of a gas tube and a grilling head, which emits a flame. When the flame heats the inside of the high borosilicate glass tube, the tube breaks at the point cut by the laser cutting machine. The high borosilicate glass tube then falls onto the surface of the gas tube, and can then be removed from the gas tube.
[0003] Because there is a certain height difference between the high borosilicate glass tube and the air tube of the barbecue bar, the high borosilicate glass tube is easily damaged when it falls onto the surface of the air tube. Therefore, this application provides a high borosilicate glass tube cutting device to meet the needs. Summary of the Invention
[0004] This invention provides a borosilicate glass tube cutting device to solve the problem that borosilicate glass tubes are easily damaged when they fall onto the surface of the gas pipe.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0006] A high borosilicate glass tube cutting device includes a support base, on the top of which a laser cutter and a sliding base are mounted. A barbecue rod is fixed to the top of the sliding base via a bracket. The device also includes:
[0007] The support mechanism includes several spring pieces installed on the surface of the barbecue rod. The highest point of the spring pieces is higher than the highest point of the fire outlet of the barbecue rod, and the bending direction of the spring pieces is towards the fire outlet of the barbecue rod.
[0008] During the glass tube cutting process, the glass tube is cut using both a laser cutter and a barbecue grill. After being cut, the glass tube falls onto the top of the spring.
[0009] Preferably, the surface of the barbecue rod is movably fitted with an upper mounting seat and a lower mounting seat, which are fixedly connected by screws. The top of the upper mounting seat is a flat structure, and a spring clip is fixed to the top of the upper mounting seat.
[0010] Preferably, the end of the spring sheet is integrally formed with a curved portion, which bends downward.
[0011] Preferably, the end of the curved portion is integrally formed with an elastic portion, and the bottom of the elastic portion is attached to the surface of the upper mounting base.
[0012] Preferably, the end of the elastic part is integrally formed with a warped portion, which is warped upward and fits against the surface of the upper mounting base.
[0013] Preferably, a rubber strip is fixed near the top of the spring sheet.
[0014] Preferably, the surface of the rubber strip is covered with a nylon layer.
[0015] Compared with the prior art, this utility model has at least the following beneficial effects:
[0016] In the above solution, by setting a spring, when the glass tube is cut, the glass tube is cut by both the laser cutter and the barbecue rod. After the glass tube is cut, it falls on the top of the spring. At this time, the spring deforms downward. The deformation of the spring converts the kinetic energy of the glass tube when it falls into the elastic potential energy of the spring, thereby preventing the glass tube from directly hitting the surface of the barbecue rod and achieving protection for the glass tube.
[0017] By incorporating a curved section that bends downwards, the end of the spring clip is prevented from scratching the inner wall of the glass tube when it is removed, thus protecting the glass tube.
[0018] By incorporating an elastic portion and a warping portion, the elastic portion is supported on the top of the upper mounting base. When the spring deforms downwards, the elastic portion can assist in supporting the spring, preventing damage caused by excessive bending of the spring end. The elastic portion can also limit excessive deformation of the spring, assist in its reset, and improve the durability of the spring. The upwardly curved warping portion can reduce the friction between the elastic portion and the top of the upper mounting base, making the elastic portion slide more smoothly on the upper mounting base.
[0019] By incorporating a rubber strip and a nylon layer, the rubber strip provides additional cushioning for the glass tube, further preventing damage. The nylon layer reduces friction between the inner wall of the glass tube and the rubber strip, making it easier to remove the glass tube from the spring clip. Attached Figure Description

Detailed Implementation
[0026] The following is a detailed description of a high borosilicate glass tube cutting device provided by this utility model, in conjunction with the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; for some known technologies, those skilled in the art can also use other alternative methods to implement the invention. Furthermore, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.
[0027] like Figures 1-4 As shown, an embodiment of this utility model provides a high borosilicate glass tube cutting device, including a support base 1, a laser cutter 2 and a sliding base 3 mounted on the top of the support base 1, and a barbecue rod 4 fixed to the top of the sliding base 3 by a bracket. The barbecue rod 4 consists of a gas pipe and a barbecue head. The barbecue head can emit flames, and the gas pipe is used to transport combustion gas and support the barbecue head. The device also includes:
[0028] The support mechanism 5 includes several spring pieces 8 installed on the surface of the barbecue rod 4. The highest point of the spring piece 8 is higher than the highest point of the fire outlet of the barbecue rod 4, and the bending direction of the spring piece 8 is towards the fire outlet of the barbecue rod 4.
[0029] During glass tube cutting, the glass tube is cut jointly by a laser cutter 2 and a barbecue rod 4. After cutting, the glass tube falls onto the top of a spring 8. The support base 1 provides a stable foundation for the entire device. The laser cutter 2 is responsible for precisely cutting the glass tube. The sliding base 3 can adjust the position of the barbecue rod 4 to accommodate glass tubes of different lengths. The barbecue rod 4 heats the glass tube at the point to be cut using the thermal expansion and contraction properties of borosilicate glass. The highest point of the spring 8 is higher than the flame outlet of the barbecue rod 4, ensuring that the cut glass tube falls onto the spring 8 first rather than directly impacting the barbecue head of the barbecue rod 4, thus avoiding cracks caused by the high-temperature glass tube due to impact. The spring 8 bends towards the flame outlet, making it easy to remove the glass tube. Several springs 8 can fit against the surface of the glass tube to form multi-point support, dispersing the impact force. When the glass tube falls, the spring 8 undergoes elastic deformation, converting kinetic energy into elastic potential energy, achieving buffering, effectively protecting the borosilicate glass tube from damage, and improving the yield rate.
[0030] like Figure 2 and Figure 3 As shown in this embodiment, an upper mounting base 6 and a lower mounting base 7 are movably fitted onto the surface of the barbecue rod 4. The upper mounting base 6 and the lower mounting base 7 are fixedly connected by screws. The top of the upper mounting base 6 is a flat structure, and the spring piece 8 is fixed to the top of the upper mounting base 6. The upper mounting base 6 and the lower mounting base 7 are fixed by screws to form an adjustable clamping structure, which can slide along the surface of the barbecue rod 4 and be fixed in any position. By adjusting the distance between the spring piece 8 and the cutting point, it is ensured that the glass tube falls accurately onto the spring piece 8. The flat design of the upper mounting base 6 provides a stable fixing base for the spring piece 8, ensuring that the spring piece 8 will not deflect or deform due to the tilt of the mounting surface when subjected to force, thus ensuring a uniform buffering effect. This detachable structure also facilitates the replacement and maintenance of the spring piece 8, extending the overall service life of the device when the spring piece 8 fails due to fatigue.
[0031] like Figure 3 and Figure 4 As shown in this embodiment, the end of the spring 8 is integrally formed with a curved portion 9. The curved portion 9 bends downward, which can eliminate the sharp edges of the end of the spring 8 and prevent the spring 8 from scratching the inner wall of the glass tube when it is removed. The arc transition of the curved portion 9 can also guide the glass tube to slide out smoothly, reduce the resistance when removing the tube, avoid accidental breakage of the glass tube due to forced pulling, and improve operational safety.
[0032] like Figure 3 and Figure 4As shown in this embodiment, the end of the bent portion 9 is integrally formed with an elastic portion 10. The bottom of the elastic portion 10 is attached to the surface of the upper mounting base 6. The elastic portion 10 and the spring piece 8 form a "double elastic support structure". When the spring piece 8 deforms downward due to the weight of the glass tube, the elastic portion 10 will be compressed and deformed simultaneously, generating an upward auxiliary elastic force, which can share the stress borne by the spring piece 8 and prevent the spring piece 8 from permanent deformation or breakage due to excessive bending, especially when cutting large-diameter glass tubes. The elastic portion 10 is supported on the surface of the upper mounting base 6 and can also limit the maximum deformation of the spring piece 8 to prevent damage due to excessive deformation. After the glass tube is removed, the rebound force of the elastic portion 10 can assist the spring piece 8 to quickly return to its original position, ensuring that the spring piece 8 is in the optimal support position for the next cut.
[0033] like Figure 3 and Figure 4 As shown in this embodiment, the end of the elastic part 10 is integrally formed with a warped part 11. The warped part 11 is warped upward and fits against the surface of the upper mounting base 6. The upward warping of the warped part 11 can reduce sliding friction.
[0034] like Figure 3 and Figure 4 As shown in this embodiment, a rubber strip 12 is fixed near the top of the spring 8. The rubber strip 12 has excellent elasticity and buffering performance, and can form a "flexible contact layer" between the glass tube and the spring 8 to further absorb the impact of falling and avoid stress concentration caused by direct collision between the glass tube and the metal spring 8.
[0035] like Figure 3 and Figure 4 As shown in this embodiment, the surface of the rubber strip 12 is wrapped with a nylon layer 13. The nylon layer 13 has a low coefficient of friction and high wear resistance. Wrapping it on the surface of the rubber strip 12 can significantly reduce the frictional resistance between the glass tube and the rubber strip 12, allowing the glass tube to slide out smoothly when it is removed, and preventing the glass tube from getting stuck on the spring 8 due to excessive friction. The nylon layer 13 can also protect the rubber strip 12 from high temperature. The heat generated when the barbecue rod 4 is working may cause the rubber to age. The heat resistance of the nylon layer 13 can extend the service life of the rubber strip 12, while preventing the rubber from sticking to the high-temperature glass tube.
[0036] Working principle: Check the status of each component of the device to ensure that the support base 1 is stable, the laser cutter 2 and the sliding base 3 are in the correct positions, and the barbecue rod 4 is firmly installed; check the support mechanism 5 to see that the upper mounting base 6 and the lower mounting base 7 are fixed to the surface of the barbecue rod 4 with screws, the spring piece 8 is fixed to the top of the upper mounting base 6, the highest point of the spring piece 8 is higher than the highest point of the fire outlet of the barbecue rod 4, and the bending direction is towards the fire outlet. The bent part 9 at the end of the spring piece 8 bends downward, the elastic part 10 supports the surface of the upper mounting base 6, the warped part 11 warps upward and fits the upper mounting base 6, and the rubber strip 12 and the surface nylon layer 13 are intact;
[0037] Place the high borosilicate glass tube to be cut at the processing position between the laser cutting machine 2 and the barbecue rod 4, ensuring that the part of the glass tube to be cut is aligned with the cutting head of the laser cutting machine 2 and the flame outlet of the barbecue rod 4;
[0038] Start the laser cutter 2 and the barbecue rod 4. The laser cutter 2 cuts the glass tube, while the barbecue rod 4 sprays flames to assist in heating, so that they can cut together.
[0039] After cutting, the glass tube falls under the action of gravity and lands on the top of the spring 8. The spring 8 deforms downward under the action of gravity, converting the kinetic energy of the falling glass tube into elastic potential energy. The rubber strip 12 further buffers the glass tube and prevents it from directly hitting the barbecue bar 4. The nylon layer 13 reduces the friction between the glass tube and the rubber strip 12.
[0040] After the glass tube stabilizes, the operator grabs the end of the glass tube and slides the glass tube along the surface of the spring 8. The curved part 9 avoids scratching the inner wall of the glass tube, and the nylon layer 13 makes the sliding smoother and makes it easier to remove the glass tube.
[0041] After the glass tube is removed, the spring 8 returns to its original position under the action of its own elasticity and the elastic part 10. The warped part 11 reduces the friction between the elastic part 10 and the upper mounting base 6, ensuring smooth repositioning.
[0042] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
