Description

Technical Field

[0001] This utility model belongs to the field of gas hose processing technology, specifically relating to a cutting device for gas hose processing. Background Technology

[0002] As an important connecting component of the gas transmission system, the processing precision of gas hoses directly affects the sealing performance and safety of use. In the hose production process, the cutting process is a key step to ensure the flatness of the pipe end and avoid deformation defects. Traditional cutting equipment mostly uses manual positioning combined with mechanical cutters.

[0003] However, when cutting existing gas hoses using rotary blades or saw blades, uneven circumference, wall thickness differences, or material elasticity can easily lead to tilted cuts and burr residue, affecting the sealing of subsequent joints and potentially causing gas leaks. This not only affects the normal use of gas equipment but may also threaten the personal safety of users. Therefore, this utility model provides a cutting device for processing gas hoses. Utility Model Content

[0004] The purpose of this invention is to provide a cutting device for processing gas hoses, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cutting device for processing gas hoses, comprising a device frame, a first frame and a second frame screwed to the top of the device frame, an auxiliary component provided inside the first frame, a support member provided at the bottom of the inner cavity of the second frame, a pressing member provided at the top of the inner cavity of the second frame directly above the support member, and a cutting component provided on one side of the inner cavity of the second frame located between the support member and the pressing member.

[0006] In a preferred embodiment, the auxiliary component includes a fixed roller rotatably connected to the inner wall of the first frame, a lifting frame is provided at the top of the inner cavity of the first frame, and a movable roller is rotatably connected to the bottom of the lifting frame.

[0007] In a preferred embodiment, an electric telescopic rod is fixedly connected to the top of the first frame, and the telescopic end of the electric telescopic rod is fixedly connected to the top of the first frame. The surfaces of both the fixed roller and the movable roller are provided with auxiliary grooves.

[0008] In a preferred embodiment, a flat "U"-shaped pressure groove is provided on the opposite surfaces of the support member and the pressing member, and a protrusion is provided inside the bottom pressure groove of the pressing member, and a deformation cavity is provided inside the protrusion.

[0009] In a preferred embodiment, the cutting assembly includes guide rails disposed on both sides of the inner cavity of the second frame, a movable plate slidably connected to the outside of the guide rails, and sliding grooves adapted to the guide rails on both sides of the movable plate. A right-angle bracket is fixedly connected to the bottom of the movable plate, and a cutting blade is bolted to the right-angle side of the right-angle bracket facing the pressing member.

[0010] In a preferred embodiment, the movable plate has two guide protrusions on the side facing the pressing member, and the pressing member has two guide grooves that are adapted to the guide protrusions on the side facing the movable plate, with a guide arc surface at the top of each guide groove.

[0011] In a preferred embodiment, the top of the second frame is provided with two sets of electric telescopic rods, the telescopic ends of the two sets of electric telescopic rods are respectively fixedly connected to the top of the moving plate and the lower pressure member, and the bottom of the equipment frame at one end of the second frame is provided with a feeding slope.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This gas hose processing cutting equipment features a moving plate that precisely engages with the guide protrusions and the guide grooves on the surface of the lower pressure component. This ensures that the cutting blade advances in a straight line along a preset path. The guide arc surface design at the top of the guide groove facilitates the quick alignment of the cutting components and their entry into the cutting position, reducing the risk of blade deviation during cutting and thus significantly reducing the probability of burrs on the cut. The right-angle frame secures the cutting blade with bolts, ensuring that the blade is strictly perpendicular to the hose axis. Combined with the linear guidance of the guide rails and slides, this achieves rigidity and stability during the cutting process and further optimizes the flatness of the cut.

[0014] This gas hose processing cutting equipment uses a flat "U"-shaped groove to forcibly constrain the hose from a free cylindrical state to a nearly flat controlled shape through three-dimensional positioning of the side walls and bottom surface. This effectively counteracts radial displacement caused by uneven wall thickness (such as thicker joint sections and thinner middle sections) or material elasticity (such as the resilience of rubber and plastic substrates), preventing local bulging or depression of the hose during cutting, ensuring that the cutting plane remains perpendicular to the hose axis, and preventing indentations or tilting of the cutting surface due to stress concentration.

[0019] The present invention will be further described below with reference to the embodiments.

[0020] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0021] Please see Figure 1-3 This utility model provides a cutting device for processing gas hoses, including a device frame 1. The top of the device frame 1 is screwed with a first frame 2 and a second frame 3. The first frame 2 is provided with an auxiliary component inside. The auxiliary component includes a fixed roller 7 rotatably connected to the inner wall of the first frame 2. The top of the inner cavity of the first frame 2 is provided with a lifting frame 5. The bottom of the lifting frame 5 is rotatably connected with a movable roller 6. The top of the first frame 2 is fixedly connected with an electric telescopic rod 4. The telescopic end of the electric telescopic rod 4 is fixedly connected to the top of the first frame 2. The surfaces of the fixed roller 7 and the movable roller 6 are both provided with auxiliary grooves 601.

[0022] The gas hose cutting equipment is in the initial preparation stage. The electric telescopic rod 4 is in the retracted state. At this time, it drives the lifting frame 5 to rise, and the moving roller 6 rises accordingly. The moving roller 6 and the fixed roller 7 maintain a large distance to provide sufficient space for the subsequent insertion of the gas hose. The operator inserts the gas hose to be cut horizontally from the end of the first frame 2 away from the second frame 3. Since the fixed roller 7 and the moving roller 6 are both provided with auxiliary grooves 601.

[0023] During the insertion of the gas hose, the auxiliary groove 601 can play a guiding role, helping the hose to smoothly enter between the fixed roller 7 and the moving roller 6. The shape of the auxiliary groove 601 is adapted to the outer contour of the hose, which can increase the contact area between the hose and the roller, making the hose more stable during the initial positioning and less prone to left and right deviation.

[0024] Once the gas hose is inserted into the appropriate position, the electric telescopic rod 4 is activated. The telescopic end of the electric telescopic rod 4 extends downward, pushing the lifting frame 5 to descend. As the lifting frame 5 descends, the moving roller 6 also descends synchronously, gradually approaching the fixed roller 7. The moving roller 6 and the fixed roller 7 cooperate with each other, applying a uniform clamping force to the gas hose through the auxiliary groove 601, stably clamping the hose between the two. At this time, the gas hose is fixed within the first frame 2, preparing for the subsequent cutting process.

[0025] In this embodiment, a support member 9 is provided at the bottom of the inner cavity of the second frame 3, and a pressing member 8 is provided at the top of the inner cavity of the second frame 3 directly above the support member 9. A cutting assembly is provided on one side of the inner cavity of the second frame 3, located on the support member 9 and the pressing member 8. A flat "U"-shaped pressing groove is provided on the opposite surfaces of the support member 9 and the pressing member 8. A protrusion 801 is provided inside the pressing groove at the bottom of the pressing member 8, and a deformation cavity 802 is provided inside the protrusion 801. The cutting assembly includes guide rails 301 disposed on both sides of the inner cavity of the second frame 3. A moving plate 10 is slidably connected to the outside of the guide rails 301. A sliding groove 1001 adapted to the guide rails 301 is provided on both sides of the moving plate 10. A right-angle frame 1002 is fixedly connected to the bottom of the 10. A cutting blade 11 is bolted to the right-angle side of the right-angle frame 1002 facing the lower pressing member 8. Two guide protrusions 1003 are provided on the side of the moving plate 10 facing the lower pressing member 8. Two guide grooves 803 that are adapted to the guide protrusions 1003 are provided on the side of the lower pressing member 8 facing the moving plate 10. A guide arc surface 804 is opened at the top of each guide groove 803. Two sets of electric telescopic rods 4 are provided at the top of the second frame 3. The telescopic ends of the two sets of electric telescopic rods 4 are fixedly connected to the top of the moving plate 10 and the lower pressing member 8, respectively. A feeding slope 101 is provided at the bottom of the equipment frame 1 located at one end of the second frame 3.

[0026] After the gas hose is positioned and initially clamped by the auxiliary components of the first frame 2, it is continuously conveyed into the second frame 3, entering the area between the support member 9 and the pressing member 8. The support member 9 and the pressing member 8 are initially unclamped. The pressing member 8 is in a high position under the pull of the electric telescopic rod 4, with enough space between them for the hose to pass smoothly. Control one of the sets of electric telescopic rods 4 at the top of the second frame 3 to extend its telescopic end downward, pushing the pressing member 8 downward. As the pressing member 8 moves downward, the guide groove 803 on it gradually approaches the guide protrusion 1003 on the moving plate 10. Since the top of the guide groove 803 is provided with a guide arc... Even if there is a slight positional deviation between the moving plate 10 and the pressing member 8 in the initial state, the guiding arc surface 804 can guide the guide protrusion 1003 to smoothly enter the guide groove 803 to achieve precise alignment. As the pressing member 8 continues to press down, the support member 9 and the flat "U" shaped groove on the pressing member 8 gradually clamp the gas hose. The two side walls and bottom surface of the flat "U" shaped groove form a three-dimensional limit, so that the hose changes from a free cylindrical state to a nearly flat controlled state. The protrusion 801 at the bottom of the pressing member 8 contacts the surface of the hose, and the deformation cavity 802 inside it can undergo a certain deformation to buffer the pressure and ensure that the hose is clamped stably and without damage.

[0027] After the hose is clamped and fixed, another set of electric telescopic rods 4 is controlled to move, pushing the moving plate 10 to move along the guide rail 301. The sliding grooves 1001 on both sides of the moving plate 10 cooperate with the guide rail 301 to ensure that the moving plate 10 moves stably along a straight line. The moving plate 10 drives the right angle frame 1002 and the cutting blade 11 to move together. The right angle frame 1002 fastens the cutting blade 11 with bolts to ensure that the cutting blade 11 is strictly perpendicular to the hose axis. As the moving plate 10 moves, the cutting blade 11 gradually approaches and cuts into the clamped gas hose to complete the cutting action. During the cutting process, the cooperation between the guide protrusion 1003 and the guide groove 803 always keeps the cutting blade 11 moving along the preset straight path to prevent the cutting direction from deviating.

[0028] After cutting, the electric telescopic rod 4 connected to the lower pressure member 8 is retracted, which drives the lower pressure member 8 to rise and release the clamp on the gas hose. The cut hose section slides down from between the support member 9 and the lower pressure member 8 under the action of gravity, and slides out of the equipment through the feeding inclined surface 101 at the bottom of one end of the second frame 3 of the equipment frame 1, and enters the subsequent collection or processing stage. At the same time, if it is necessary to continue cutting the next section of hose, the above process can be repeated.

[0029] The flat "U" shaped grooves on the support member 9 and the lower pressure member 8 effectively offset the radial displacement of the gas hose caused by uneven wall thickness or material elasticity through three-dimensional limiting, avoiding local bulging or depression of the pipe body during cutting, and ensuring that the cutting plane is always perpendicular to the hose axis. The protrusion 801 at the bottom of the lower pressure member 8 and its internal deformation cavity 802.

[0030] During the cutting process, stable pressure is applied to the hose to reduce hose deformation, further ensuring cutting accuracy and reducing the probability of cut tilt and dimensional deviation. The guide protrusion 1003 on the moving plate 10 and the guide groove 803 on the pressing part 8 are precisely matched to ensure that the cutting blade 11 advances in a straight line along the preset path. The guide arc surface 804 at the top of the guide groove 803 facilitates the cutting assembly to quickly align and enter the cutting position, reducing the risk of blade deviation when cutting, significantly reducing the probability of burr generation, making the cut smoother and improving product quality. The coordinated design of the guide arc surface 804, guide protrusion 1003, and guide groove 803 enables the cutting assembly to quickly and accurately find the cutting position during movement and maintain a stable cutting direction, reducing cutting deviation caused by equipment vibration or installation errors, improving the stability and reliability of equipment operation, and reducing equipment failure rate. The deformation cavity 802 inside the protrusion 801 plays a buffering role during the cutting process, effectively absorbing the impact force generated during cutting, reducing damage to the hose and equipment components, extending equipment service life, and reducing equipment maintenance costs.

[0031] The working principle and usage process of this utility model are as follows: First, the gas hose cutting equipment is in the initial preparation stage, and the electric telescopic rod 4 is in the retracted state. At this time, it drives the lifting frame 5 to rise, and the moving roller 6 rises accordingly. The moving roller 6 and the fixed roller 7 maintain a large distance to provide sufficient space for the subsequent insertion of the gas hose. The operator inserts the gas hose to be cut horizontally from the end of the first frame 2 away from the second frame 3. Since both the fixed roller 7 and the moving roller 6 are provided with auxiliary grooves 601, the auxiliary grooves 601 can guide the gas hose during insertion, helping the hose to smoothly enter between the fixed roller 7 and the moving roller 6. The shape of the auxiliary groove 601 is adapted to the outer contour of the hose, which can increase the contact area between the hose and the roller, so that the hose can smoothly enter between the fixed roller 7 and the moving roller 6. The initial positioning is more stable and less prone to lateral deviation. After the gas hose is inserted into the appropriate position, the electric telescopic rod 4 is activated. The telescopic end of the electric telescopic rod 4 extends downward, pushing the lifting frame 5 down. As the lifting frame 5 descends, the moving roller 6 also descends synchronously, gradually approaching the fixed roller 7. The moving roller 6 and the fixed roller 7 cooperate with each other, applying a uniform clamping force to the gas hose through the auxiliary groove 601, stably clamping the hose between them. At this time, the gas hose is fixed in the first frame 2, preparing for the subsequent cutting process. After the auxiliary components of the first frame 2 complete the positioning and initial clamping, the gas hose is continuously conveyed into the second frame 3, entering the area between the support member 9 and the pressing member 8. The support member 9 and the pressing member 8 are in the initial un-positioned state. In the clamped state, the lower pressure member 8 is in a high position under the pull of the electric telescopic rod 4, with enough space between them for the hose to pass smoothly. Control one of the electric telescopic rods 4 at the top of the second frame 3 to extend its telescopic end downward, pushing the lower pressure member 8 downward. As the lower pressure member 8 moves downward, its guide groove 803 gradually approaches the guide protrusion 1003 on the moving plate 10. Since the top of the guide groove 803 is provided with a guide arc surface 804, even if there is a slight positional deviation between the moving plate 10 and the lower pressure member 8 in the initial state, the guide arc surface 804 can guide the guide protrusion 1003 to smoothly enter the guide groove 803, achieving precise alignment. As the lower pressure member 8 continues to press down, the support member 9 and the flat "U"-shaped pressure groove on the lower pressure member 8 gradually press the gas... The hose is clamped, and the two side walls and bottom surface of the flat "U"-shaped pressure groove form a three-dimensional limit, changing the hose from a free cylindrical state to a nearly flat controlled shape. The protrusion 801 at the bottom of the lower pressure member 8 contacts the surface of the hose, and its internal deformation cavity 802 can undergo a certain deformation to buffer the pressure and ensure that the hose is clamped stably and without damage. After the hose is clamped and fixed, the other set of electric telescopic rods 4 is controlled to move, pushing the moving plate 10 to move along the guide rail 301. The sliding grooves 1001 on both sides of the moving plate 10 cooperate with the guide rail 301 to ensure that the moving plate 10 moves stably in a straight line. The moving plate 10 drives the right angle frame 1002 and the cutting blade 11 to move together. The right angle frame 1002 is fastened to the cutting blade 11 with bolts to ensure that the cutting blade 11 is strictly perpendicular to the hose axis.As the moving plate 10 moves, the cutting blade 11 gradually approaches and cuts into the clamped gas hose, completing the cutting action. During the cutting process, the cooperation between the guide protrusion 1003 and the guide groove 803 ensures that the cutting blade 11 moves along a preset straight path, preventing deviation in the cutting direction. After cutting, the electric telescopic rod 4 connected to the lower pressure member 8 is retracted, causing the lower pressure member 8 to rise and release the clamping of the gas hose. The cut hose segment slides down between the support member 9 and the lower pressure member 8 under the action of gravity, and slides out of the equipment via the feeding ramp 101 located at the bottom of one end of the second frame 3 of the equipment frame 1, entering the subsequent collection or processing stage. If it is necessary to cut another section of hose, the above process can be repeated.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
