Description

Technical Field

[0001] This invention relates to the field of cutting equipment technology, specifically to a steel wire braided hose cutting device. Background Technology

[0002] Steel wire braided rubber hoses consist of a liquid-resistant inner layer of synthetic rubber, a middle layer, one to three layers of steel wire braiding reinforcement, and an outer layer of synthetic rubber with excellent weather resistance. The steel wire braided rubber hoses need to be cut to appropriate lengths according to actual usage requirements.

[0003] Currently, common cutting methods include punching and shearing, serrated blade sawing, abrasive wheel cutting, and laser cutting. Existing cutting equipment typically includes a machine body, clamping mechanism, cutting mechanism, and feeding mechanism. The steel wire is prone to shifting during cutting, affecting cutting accuracy. Existing clamping mechanisms generally use upper and lower clamping blocks to hold the hose. The hose surface is made of rubber, with an internal steel wire braided layer. Insufficient clamping force results in an unstable clamp, causing the hose to slip and shift during cutting. Excessive clamping force can flatten the hose, causing cross-sectional deformation and affecting subsequent sealing performance. Furthermore, the cutting process generates a large amount of rubber particles and dust. Dust accumulation on the equipment not only pollutes the working environment but also generates heat during cutting, with some rubber particles heated above their ignition point, forming sparks that can easily ignite the accumulated dust, posing a safety hazard. Summary of the Invention

[0004] This invention proposes a steel wire braided hose cutting device to solve the problems of difficult clamping force control and cutting dust in the prior art.

[0005] The technical solution of the present invention is as follows:

[0006] A steel wire braided hose cutting device includes a machine body and a cutting blade, and further includes:

[0007] A guide tube, which is disposed on the machine body, is used to limit and guide the hose;

[0008] A clamping assembly, disposed on the machine body, is used to clamp and fix the cutting area of ​​the hose. The clamping assembly includes:

[0009] An annular inflatable seat is coaxially fixed on the guide tube. Two annular inflatable seats are provided, and the cutter is located between the two annular inflatable seats.

[0010] An annular airbag is disposed inside the annular inflatable base and outside the tubing.

[0011] A protective cover, which is movably mounted on the machine body, is used to shield and protect the cutting position. The protective cover is made of transparent material.

[0012] Dust collection assembly, used to absorb cutting dust within the protective cover, the dust collection assembly comprising:

[0013] A vacuum cleaner hose, which is connected to the protective cover;

[0014] A dust collection chamber is connected to the dust suction pipe, and a vacuum pump is connected to the dust collection chamber. The vacuum pump is used to suck dust into the dust collection chamber.

[0015] An adsorption element, disposed inside the dust collection chamber, is used to adsorb and filter dust and odors. The adsorption element includes:

[0016] The dust collection chamber has a replacement port, and the replacement box can be pulled out and installed in the replacement port. The interior of the replacement box is filled with an activated carbon filter layer.

[0017] A cooling assembly, disposed inside the protective cover, is used to cool the hose and the cutter. The cooling assembly includes:

[0018] A cold air duct, which is connected to a cold air blower, is used to blow cold air to the cutting position;

[0019] Both the guide tube and the annular air-filled seat have liquid storage chambers on their side walls. The liquid storage chambers are connected to a coolant circulation pipe, and the cold air pipe is connected to a heat exchange pipe, which is located inside the liquid storage chamber.

[0020] A traction assembly, disposed on the machine body, is used to pull the hose and flare and shape the end of the hose. The traction assembly includes:

[0021] A traction seat, which is movably mounted on the machine body;

[0022] A shaping block, which is movably mounted on the traction seat, is conical in shape;

[0023] An external clamp, disposed on the traction seat, is used to cooperate with the shaping block to clamp the side wall of the hose. The external clamp includes:

[0024] A clamping block, which is rotatably mounted on the traction seat, is used to fit against the outer wall of the hose.

[0025] To improve the cooling effect on the hose, the cold air duct is rotatably connected to an air supply seat, the air supply seat is connected to the air cooler, and the cold air duct is rotatably mounted on the air supply seat.

[0026] The working principle and beneficial effects of this invention are as follows:

[0027] 1. In this invention, by setting an annular inflatable seat and an annular airbag, a flexible clamping force is applied to the hose, which not only avoids the hose from shifting or slipping during cutting and improves the cutting accuracy, but also effectively prevents the hose from being flattened due to excessive clamping force, thus ensuring the sealing performance of subsequent connections.

[0028] 2. In this invention, by setting a movable transparent protective cover, a closed cutting space is formed during cutting, which allows for direct observation of the cutting status and effectively prevents dust and sparks generated during cutting from splashing outward. At the same time, a dust collection component is set up in conjunction with a cold air duct, and a vacuum pump is used to draw the gas containing dust and odor into the dust collection chamber. After being adsorbed and filtered by the activated carbon filter layer, it is discharged, which significantly improves the working environment and reduces the safety hazards caused by high temperature dust accumulation.

[0029] 3. In this invention, by setting up a cold air duct to blow cold air to the cutting position, and using the coolant in the guide tube and the annular air seat to further cool the cold air duct, the heat generated by cutting can be quickly removed, effectively reducing the temperature of the rubber tube and the cutter, preventing the rubber particles from melting or generating sparks due to high temperature, and further ensuring the cutting quality and operational safety.

[0030] 4. In this invention, by setting up a traction component, and utilizing the cooperation of a movable traction seat, a conical shaping block and an external clamp, while completing the fixed-length traction of the hose, the shaping block can perform flaring and shaping treatment on the cut hose end, effectively repairing the port deformation caused by cutting, improving the roundness and dimensional accuracy of the hose end, and facilitating subsequent joint installation operations.

[0047] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0048] like Figures 1 to 2 As shown in the figure, this embodiment proposes a steel wire braided hose cutting device, including a machine body 1 and a cutter 2. The cutter 2 is movably mounted on the machine body 1 by a drive cylinder. It also includes a guide tube 3, a clamping assembly, a protective cover 4, a dust collection assembly, a cooling assembly, and a traction assembly.

[0049] The guide tube 3 is installed on the machine body 1 and is used to limit and guide the hose. There are two guide tubes 3, which are located on both sides of the cutting position. The hose passes through the guide tube 3 and is limited by the guide tube 3 to ensure the straightness of the hose during conveying, reduce the bending of the hose, and thus improve the positional accuracy during cutting.

[0050] The clamping assembly is mounted on the machine body 1 and is used to clamp and fix the cutting area of ​​the hose, such as... Figures 1 to 3 As shown, the clamping assembly includes an annular inflatable seat 101 and an annular airbag 102. The annular inflatable seat 101 is coaxially fixed on the guide tube 3. There are two annular inflatable seats 101, and the cutter 2 is located between the two annular inflatable seats 101. The annular airbag 102 is located inside the annular inflatable seat 101 and outside the rubber tube. The rubber tube passes through the annular airbag 102. The two annular inflatable seats 101 are connected to an external air source through an inflation tube. By inflating, the annular airbag 102 expands and fits against the outer wall of the rubber tube, forming a flexible clamping force. This avoids rigid compression that could cause deformation of the rubber tube, while ensuring the stability of the clamping. It can also adapt to rubber tubes of different diameters, improving the versatility of the equipment.

[0051] The protective cover 4 is movably mounted on the machine body 1 to shield and protect the cutting position. The protective cover 4 is made of transparent material. There are two protective covers 4. A slider is fixedly mounted on the protective cover 4. The machine body 1 has a sliding groove that matches the slider. The protective cover 4 can slide by the cooperation of the slider and the sliding groove. When the two protective covers 4 come close to each other and close, they form a closed cutting chamber to block dust and sparks from splashing out. The transparent material also makes it easy to observe the internal cutting status in real time.

[0052] The dust collection assembly is used to absorb cutting dust inside the protective cover 4, such as... Figure 1 and Figure 5 As shown, the dust collection assembly includes a suction pipe 201, a dust collection chamber 202, and an adsorption component. The suction pipe 201 is connected to the protective cover 4, and the dust collection chamber 202 is connected to the suction pipe 201. A vacuum pump 203 is connected to the dust collection chamber 202, which is used to draw dust into the dust collection chamber 202. The adsorption component is located inside the dust collection chamber 202 and is used to adsorb and filter dust and odors. The adsorption component includes a replacement box 301, and a replacement port is provided on the dust collection chamber 202. The replacement box 301 is removable and has an activated carbon filter layer 302 inside. The dust collection chamber 202 is kept under negative pressure by the vacuum pump 203, which draws dust and odor-containing gas from the protective cover 4 into the dust collection chamber 202. The activated carbon filter layer 302 adsorbs odor molecules and filters dust, improving the cleanliness of the exhaust gas. The removable design of the replacement box 301 facilitates later maintenance, and the activated carbon filter layer 302 inside can be replaced.

[0053] The cooling component is located inside the protective cover 4 and is used to cool the hose and cutter 2, such as... Figures 1 to 3 and Figure 6As shown, the cooling assembly includes a cold air duct 401, which is connected to a cooler 402 for blowing cold air to the cutting position. The cold air duct 401 is rotatably connected to an air supply seat 403, which is connected to the cooler 402. The cold air duct 401 is rotatably mounted on the air supply seat 403, and a motor 404 is mounted on the air supply seat 403. The output end of the motor 404 is connected to the cold air duct 401 via a gear set. Liquid storage chambers are provided on the side walls of the guide tube 3 and the annular air filling seat 101. The liquid storage chambers are connected to a coolant circulation pipeline. The cold air duct 401 is connected to a heat exchange tube 405, which is located inside the liquid storage chamber. The air cooler 402 delivers cold air to the interior of the air cooler duct 401 through the air supply seat 403. The cooling circulation pipeline is connected to the external refrigeration equipment, which delivers coolant to the liquid storage chamber to further cool the cold air in the heat exchange tube 405. At the same time, it cools the guide tube 3, the annular air inflator 101 and the annular air bag 102, thereby cooling the hose. The motor 404 drives the air cooler duct 401 to rotate, expanding the blowing range of the air cooler duct 401. The cold air blown by the air cooler duct 401 cools the cutter 2 and the hose. At the same time, the blown cold air can blow the dust generated by cutting towards the dust collection pipe 201, improving the dust collection efficiency.

[0054] The traction assembly is mounted on the machine body 1 and is used to pull the hose and flare and shape the hose end, such as... Figure 2 , Figure 4 and Figure 7As shown, the traction assembly includes a traction seat 501, a shaping block 502, and an outer clamp. The traction seat 501 is movably mounted on the machine body 1. A driven rack 503 is fixedly mounted on the machine body 1. A second motor 504 is mounted on the traction seat 501. A drive gear 505 is fixedly mounted on the output end of the second motor 504. The drive gear 505 meshes with the driven rack 503. A limit block is fixedly mounted on the second motor 504. A limit groove matching the limit block is opened on the driven rack 503. Multiple driven racks 503 are provided. The driven racks 503 pass through... A bolt is detachably mounted on the machine body 1. The length of the driven rack 503 can be adjusted to regulate the maximum stroke of the traction seat 501. A second motor 504 can drive the drive gear 505 to rotate, causing the traction seat 501 to move along the driven rack 503. A shaping block 502 is movably mounted on the traction seat 501. An electric push rod 506 is mounted on the traction seat 501. The shaping block 502 is fixedly mounted on the output end of the electric push rod 506. The shaping block 502 is conical, and an outer clamp is mounted on the traction seat 501 to cooperate with the shaping block 502. The hose is clamped against its side wall. The outer clamp includes a clamping block 601, which is rotatably mounted on a traction seat 501 to fit against the outer wall of the hose. A rotating shaft is fixedly connected to the clamping block 601 and rotatably mounted on the traction seat 501. An electric push rod 602 is mounted on the traction seat 501. A drive rack 603 is fixedly mounted at the output end of the electric push rod 602. A driven gear 604 is fixedly mounted on the rotating shaft. The driven gear 604 meshes with the drive rack 603. The annular airbag 102 provides initial positioning of the hose. Motor 506 can drive the shaping block 502 to be inserted into the end of the hose. Electric push rod 602 drives the clamping block 601 to rotate and cooperate with the shaping block 502 to stably clamp the hose. Then, air is drawn into the annular air seat 101 to release the limit of the annular air bag 102 on the hose. Motor 504 drives the drive gear 505 to rotate, which can drive the traction seat 501 to move along the driven rack 503 to pull the hose. After the hose moves the required length, motor 504 stops. The annular air bag 102 clamps the hose and can cut the hose to a fixed length.

[0055] When using this steel wire braided hose cutting equipment, the operator first adjusts the initial inflation pressure of the annular airbag 102 according to the diameter and cutting length of the hose to be cut, and adjusts the number of driven racks 503 to adjust the traction length. The steel wire braided hose to be cut is inserted through the guide tube 3 and passes through the annular airbag 102. The initial traction block is located at the end of another guide tube 3. Inflation is made into the annular airbag 102 to initially clamp the hose. The electric push rod 506 extends and the conical shaping block 502 is inserted into the hose port to widen and shape the port. At the same time, the electric push rod 602 drives the clamping block 601 to rotate. The clamping block 601 and the shaping block 502 cooperate to clamp the hose. The annular airbag 102 is deflated to release the limit on the hose.

[0056] Motor 2 504 drives the drive gear 505 to rotate, which drives the traction seat 501 to move along the driven rack 503 to deliver the hose to a fixed length. After reaching the set position, the traction stops. Then, the two annular airbags 102 inflate and flexibly clamp and fix the hose on both sides of the cutting area. After clamping, the cutter 2 moves downward under the drive cylinder to cut the hose.

[0057] During the cutting process, the two protective covers 4 are pushed together to close and form a closed cutting chamber. The vacuum pump 203 is started, and the dust-laden gas in the protective cover 4 enters the dust collection chamber 202 through the dust suction pipe 201. After being adsorbed and filtered by the activated carbon filter layer 302, it is discharged. At the same time, the cold air fan 402 delivers cold air to the cold air pipe 401, and the external refrigeration equipment delivers coolant to the liquid storage chamber. The coolant further cools the cold air in the heat exchange pipe 405. The cooled cold air is blown from the cold air pipe 401 to the cutting position to cool the cutter 2 and the hose, and blows the dust towards the dust suction pipe 201. The motor 404 drives the cold air pipe 401 to rotate, expanding the blowing range.

[0058] After cutting, the cutter 2 returns to its original position, the annular airbag 102 near the traction seat 501 depressurizes, releasing the clamp on the hose. The traction seat 501 continues to pull the hose out of the guide tube 3, releasing the clamp 601 from the hose and removing the hose from the shaping block 502. Then, the motor 2 504 drives the traction seat 501 to move back to the initial position to flare and shape the end of the subsequent hose and clamp it. It continues to drive the subsequent hose forward for a fixed length. By repeating the above steps, continuous fixed-length cutting, flaring and shaping, and dust removal and cooling of the hose can be achieved.

[0059] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
