Description

Technical Field

[0001] This utility model relates to the field of pipe processing, specifically an auxiliary device for cutting steel wire pipes. Background Technology

[0002] PVC steel wire pipe, also known as PVC steel wire reinforced pipe, has a three-layer structure. The inner and outer layers are soft PVC plastic, and the middle layer is a steel wire reinforcement structure, which can be steel wire mesh or spiral steel wire. After processing or before use, PVC steel wire pipe needs to be cut to the appropriate size. Currently, most of this is done manually using a cutting machine, such as the handheld cutting machine provided by the authorized cutting machine with application number CN202122165011.3. This is time-consuming and labor-intensive. Furthermore, because PVC pipe is relatively soft while the internal steel wire is relatively hard, the PVC pipe is prone to shaking and displacement when cutting the steel wire, affecting the cutting accuracy. In order to improve the cutting accuracy, the operator often needs to hold the PVC pipe close to the cutting position with their hand. The cutting machine can easily cause injury to the operator's hands, resulting in poor adaptability. Therefore, the existing equipment needs to be improved.

[0003] To improve cutting efficiency, a left-right closing cutting blade is used. The steel wire tube is placed between two cutting blades, and the tube is cut after the blades close. The steel wire tube is a flexible tube with steel wires embedded inside, such as commonly used exhaust hoses and ducts. Because it is a flexible tube, if there is no additional support during the closing process of the cutting blades, it will deform. Once deformed, it is difficult to ensure a smooth cut, thus compromising the quality of the cut steel wire tube. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an auxiliary device for steel wire pipe cutting.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] An auxiliary device for cutting steel wire pipes includes a housing, a lifting mechanism installed inside the housing, a rotating mechanism on the outside of the housing, and a support assembly on the outside of the housing. The support assembly is connected to the lifting mechanism, and the lifting mechanism is connected to the rotating mechanism. The rotating mechanism drives the lifting mechanism to move, which in turn drives the support assembly to move.

[0007] As a further improvement, the support assembly includes an outer support member and a push rod, the push rod moving through the housing, one end of the push rod being located inside the housing, and the other end of the push rod extending outward from the housing, the outer support member being movably disposed outside the housing and connected to the other end of the push rod.

[0008] As a further improvement, the outer support member is consistent with the shape of the shell and is movably fitted outside the shell; both the shell and the outer support member are circular in shape.

[0009] As a further improvement, the push rod and the outer support are fixedly connected.

[0010] As a further improvement, the lifting mechanism includes a rotating shaft and a cam, which are installed inside the housing and rotatably mounted with the housing. The cam is mounted on the rotating shaft and rotates synchronously with it. During rotation, the cam will lift the push rod.

[0011] As a further improvement, a torsion spring is installed inside the housing, which is connected to the cam and provides preload to the cam.

[0012] As a further improvement, the rotating mechanism includes a force-bearing wheel connected to a rotating shaft. A pull line is wound around the force-bearing wheel and leads to the outside of the housing. Pulling the pull line drives the force-bearing wheel to rotate, causing the rotating shaft to rotate synchronously.

[0013] As a further improvement, the housing is provided with cover plates at both ends, and the two ends of the rotating shaft are rotatably installed with the cover plates at both ends of the housing.

[0014] As a further improvement, the housing is provided with a connector, which contains a bolt that extends out of the connector.

[0015] As a further improvement, the rotating shaft is positioned along the axial center of the housing.

[0016] This utility model has the following beneficial technical effects:

[0017] This utility model is mainly used for the processing of steel wire hoses. It operates from the inside, using a push rod to push out the outer support, thereby supporting the inner surface of the steel wire hose. When the external cutting tool closes and cuts, it is supported by the outer support, preventing the steel wire hose from deforming and ensuring the smoothness of the cut.

[0026] Example 1

[0027] refer to Figure 1As shown, an auxiliary device for cutting steel wire hoses includes a housing 1, a lifting mechanism installed inside the housing 1, a rotating mechanism on the outside of the housing, and a support assembly outside the housing. The support assembly is connected to the lifting mechanism, which in turn is connected to the rotating mechanism. The rotating mechanism drives the lifting mechanism to move, thereby moving the support assembly. The support assembly extends a few millimeters outward from the housing. It is mainly used for processing steel wire hoses, in conjunction with a cutting mechanism. The cutting mechanism typically includes a support column, a left cutting blade, and a right cutting blade. The support column passes between the left and right cutting blades. The steel wire hose to be cut is fitted onto the support column, meaning the support column is inserted into the steel wire hose. The device of this application is mounted on the support column, thus allowing the device itself to be inserted into the steel wire hose as well. During cutting, the left and right cutting blades close together to cut the outside of the steel wire hose. Since the inside of the steel wire hose is held in place by the external support, the steel wire hose will not be compressed and deformed when the left and right cutting blades cut, thus ensuring the smoothness of the cut.

[0028] Example 2

[0029] refer to Figure 1 As shown, an auxiliary device for cutting steel wire hoses includes a housing 1, a lifting mechanism installed inside the housing 1, a rotating mechanism on the outside of the housing, and a support assembly outside the housing. The support assembly is connected to the lifting mechanism, which in turn is connected to the rotating mechanism. The rotating mechanism drives the lifting mechanism to move, thereby moving the support assembly. The support assembly extends a few millimeters outward from the housing. This device is mainly used for processing steel wire hoses. It works in conjunction with a cutting mechanism, which typically includes a support column, a left cutting blade, and a right cutting blade. The support column passes between the left and right cutting blades. The steel wire hose to be cut is fitted onto the support column, meaning the support column is inserted into the steel wire hose. The device in this application is mounted on the support column, thus allowing it to be inserted into the steel wire hose as well. In the aforementioned mechanisms, the support assembly includes an outer support member 2 and a push rod 3. The push rod 3 moves through the housing 1, with one end inside the housing 1 and the other end extending outward from the housing 1. The outer support member 2 is movably positioned outside the housing 1 and connected to the other end of the push rod 3. The housing 1 is circular, and the corresponding outer support 2 is also circular, essentially creating a movable outer shell around the housing. When the push rod 3 extends outward, it causes the outer support 2 to extend a certain distance beyond the housing 1, typically set to 3-5mm. Of course, for steel wire hoses of different diameters, outer supports of different diameters can be selected to accommodate various sizes of steel wire hoses. The push rod and outer support can be separated; by adjusting the length of the push rod, it can be adapted to various diameters of steel wire hoses.

[0030] The structure of the outer support 2 and the push rod 3 can be a one-piece structure, that is, the outer support and the push rod can be directly fabricated from a single plate or other material to form a single integrated structure, such as... Figure 2 As shown. Alternatively, the outer support 2 and the push rod 3 can be two independent separate components, with the push rod 3 assembled inside the outer support 2 and then locked together by screws.

[0031] Example 3

[0032] An auxiliary device for cutting steel wire hoses includes a housing 1, a lifting mechanism installed inside the housing 1, a rotating mechanism on the outside of the housing, and a support assembly outside the housing. The support assembly is connected to the lifting mechanism, which in turn is connected to the rotating mechanism. The rotating mechanism drives the lifting mechanism to move, thereby moving the support assembly. The support assembly extends a few millimeters outward from the housing. It is mainly used for processing steel wire hoses, in conjunction with a cutting mechanism. The cutting mechanism typically includes a support column, a left cutting blade, and a right cutting blade. The support column passes between the left and right cutting blades. The steel wire hose to be cut is fitted onto the support column, meaning the support column is inserted into the steel wire hose. The device in this application is mounted on the support column, thus allowing the device to also be inserted into the steel wire hose. The lifting mechanism includes a rotating shaft 4 and a cam 5. The rotating shaft 4 is installed inside the housing 1 and rotatably mounted with it. The cam 5 is mounted on the rotating shaft 4 and rotates synchronously with it. During rotation, the cam 5 lifts a push rod 3. The cam surface has uneven areas. When the outer support contacts the housing surface, the push rod is retracted to its maximum extent inside the housing, just touching the lowest point of the cam surface. As the cam rotates, when the higher part of the cam surface contacts the push rod, it pushes the push rod outward, causing the push rod to drive the outer support to extend outward, thus completing the support and pushing of the steel wire hose.

[0033] Additionally, a torsion spring 6 is installed inside the housing 1. This torsion spring 6 is connected to the cam 5 and provides preload to the cam 5. When the cam is not subjected to rotational force, the torsion spring helps maintain the cam in its initial state, at which point the lowest point of the cam contacts the push rod, and the outer support is flush with the housing and does not extend. After the cam rotates, it is subjected to the restoring force of the torsion spring. When the restoring force is released, the cam and the shaft automatically return to their original positions.

[0034] Example 4

[0035] refer to Figure 1As shown, an auxiliary device for cutting steel wire hoses includes a housing 1, a lifting mechanism installed inside the housing 1, a rotating mechanism on the outside of the housing, and a support assembly outside the housing. The support assembly is connected to the lifting mechanism, which in turn is connected to the rotating mechanism. The rotating mechanism drives the lifting mechanism to move, thereby moving the support assembly. The support assembly extends a few millimeters outward from the housing. It is mainly used for processing steel wire hoses, in conjunction with a cutting mechanism. The cutting mechanism typically includes a support column, a left cutting blade, and a right cutting blade. The support column passes between the left and right cutting blades. The steel wire hose to be cut is fitted onto the support column, meaning the support column is inserted into the steel wire hose. The device in this application is mounted on the support column, thus allowing the device to also be inserted into the steel wire hose. The rotating mechanism includes a force-bearing wheel 7 connected to a rotating shaft 4. A pull line is wound around the force-bearing wheel 7, which leads to the outside of the housing. Pulling the pull line drives the force-bearing wheel to rotate, causing the rotating shaft to rotate synchronously. One end of the shaft is inserted into the force-bearing wheel and secured, so that the force-bearing wheel and the shaft are fixedly connected, ensuring that the shaft can rotate synchronously when the force-bearing wheel rotates.

[0036] The housing 1 has cover plates 8 at both ends, and the two ends of the rotating shaft 4 are rotatably installed with the cover plates 8 at both ends of the housing 4.

[0037] The housing 1 is equipped with a connector 9, which contains a bolt 10. The bolt extends out of the connector and is used to connect with external devices, thereby fixing the entire device in place. The bolt can also be used to fix the device to another rod-like device, thus suspending the device and facilitating the cutting of steel wire tubes by the cutting tool.

[0038] Depending on the diameter of the steel wire hose, corresponding push rods and external supports can be replaced to improve adaptability.

[0039] A pull line can be introduced into the force-bearing rotating wheel and tied tightly around the wheel at least once. Then the pull line is led out, and by pulling the pull line by hand, the force-bearing rotating wheel can be rotated, which in turn drives the rotating shaft to rotate, thereby driving the cam to rotate. By controlling the length of the pull line, the rotation angle of the cam can be controlled, thus realizing the extension distance of the outer support.

[0040] In practical applications, this utility model requires the auxiliary device to be mounted on a corresponding cutting device. A PVC hose or steel wire hose is fitted onto the auxiliary device, which is located inside the steel wire hose. Because the steel wire hose has a certain degree of flexibility, direct cutting without internal obstruction can easily result in an uneven cut, compromising the quality of the cut steel wire hose. Therefore, this utility model utilizes the auxiliary device to provide support inside the steel wire hose. Initially, the steel wire hose is slightly larger than the auxiliary device. To achieve effective support, the auxiliary device needs to expand outwards via cam 5 in the lifting mechanism. Shaft 4 can be driven by an external driver. Cam 5 is mounted on shaft 4 and rotates synchronously with it. During rotation, cam 5 lifts push rod 3. The cam surface has uneven areas. When the outer support contacts the housing surface, the push rod retracts to its maximum extent inside the housing, contacting the lowest point of the cam surface. As the cam rotates, when the higher part of the cam surface contacts the push rod, it pushes the push rod outward, causing the push rod to extend the outer support member outward, thus providing support for the wire hose. At this time, the cutting tool cuts the wire hose from the outside. The wire hose is supported internally by the outer support member, preventing bending and deformation during the cutting process and effectively obtaining a smooth cut. Moreover, by utilizing the assembly and adjustment of the outer support member and the push rod, this application can be used for cutting wire hoses of various diameters, rather than being limited to cutting only one size of wire hose. This reduces the purchase cost of the equipment, increases its applicability, and makes the overall operation simple and convenient. Structurally, it can be used in conjunction with cutting equipment, either with a separate driver to drive the shaft rotation, or sharing the same driver with external cutting equipment. Alternatively, it can be manually adjusted.

[0041] It should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
