Abstract
Description
Technical Field
[0001] This utility model relates to the field of machining tools, specifically to a hose flattening forming device. Background Technology
[0002] Rubber hoses, as important fluid transfer components, are widely used in industrial production, automotive manufacturing, electronic equipment, medical devices, and other fields. Depending on the application environment and connection requirements, hoses need to be processed into different end shapes to meet specific assembly and sealing needs. Among these, flat-ended hose ends offer unique advantages in certain special applications, such as enabling more compact connections in space-constrained environments and providing better sealing performance in specific sealing structures.
[0003] Currently, the processing of hose ends mainly employs a cutting process, which involves using a cutting tool to cut the hose to the required length, obtaining a circular cross-section perpendicular to the axis. Existing hose cutting devices typically include a positioning mechanism and a cutting mechanism. The positioning mechanism is used to fix the position of the hose, and the cutting mechanism is used to perform the cutting action. However, these devices can only achieve simple cutting of the hose and cannot change the cross-sectional shape of the hose end.
[0004] Existing technologies have significant shortcomings when it comes to manufacturing flat-mouthed hoses. While traditional manual flattening methods can alter the hose end shape to some extent, they suffer from poor forming accuracy, inconsistent results, and low efficiency. Due to the lack of specialized forming tools, operators often rely on experience and feel, making it difficult to guarantee the geometric accuracy and shape consistency of the flattened end. Furthermore, manual operation easily leads to uneven hose wall thickness, affecting product quality.
[0005] More importantly, existing technologies lack specialized equipment for forming flat ends on rubber hoses. While various hose processing equipment exists on the market, most are designed for traditional processing techniques such as cutting and bending, lacking effective technical solutions for forming the special shape required for flat ends. This technological gap severely restricts the large-scale production of rubber hose products requiring flat end connections.
[0006] Chinese patent CN204339862U discloses a hose cutting tool, which discloses a technical solution for hose cutting by using a limiting plate and a cutter. It has the technical effect of improving the cutting quality and controlling the cutting diameter, but it still does not solve the problem of forming a flat end of the hose. It can only achieve a simple circular cut and cannot change the cross-sectional shape of the hose end.
[0007] Chinese patent CN216464899U discloses a silicone tube cutting fixture, which discloses a technical solution for achieving precise cutting of silicone tubes through positioning with an arc-shaped sliding groove and support with a circular cutting groove. This solution improves the accuracy of the cutting length and the flatness of the cut. However, it still does not solve the problem of converting the end of the tube from a circular cross-section to a flat opening shape, and cannot meet the flat opening forming requirements under special connection needs.
[0008] Furthermore, in actual production, hoses typically require flattening at both ends. Using existing technology, each end needs to be processed separately, which is not only cumbersome but also makes it difficult to guarantee the consistency of the shapes at both ends, significantly reducing production efficiency. This inefficiency and inconsistent quality are particularly pronounced in mass production. Utility Model Content
[0009] The purpose of this utility model is to provide a hose flattening forming device, which can efficiently and accurately process the end of the hose into a flattened shape. It has the characteristics of simple structure, convenient operation, high forming accuracy and high production efficiency, so as to meet the technical needs of related industries for flattened hoses.
[0010] To achieve the above objectives, this utility model is implemented through the following technical solution: a hose flattening forming device, comprising a hose cutting fixture and a cutting knife;
[0011] The pipe cutting fixture has a countersunk hole inside and a guide rail on it. The guide rail communicates with the countersunk hole to form a flat slot. The width of the flat slot is smaller than the diameter of the countersunk hole and the width of the flat slot is centrally symmetrical with the countersunk hole. The cutter has a cutting edge and can move along the guide rail.
[0012] Furthermore, the cutter has an L-shaped structure.
[0013] Furthermore, the cutting edge is provided on one side of the L-shaped structure.
[0014] Furthermore, the tube cutting fixture is provided with two guide rails.
[0015] Furthermore, the two guide rails are arranged opposite each other on both sides of the tube cutting fixture.
[0016] Furthermore, the pipe cutting fixture is provided with two countersunk holes.
[0017] Furthermore, the number of cutting blades is two.
[0018] Furthermore, the cutting edge of the cutter is in close contact with the corresponding guide rail.
[0019] Compared with the prior art, the present invention has the following advantages:
[0020] I. This utility model provides a device specifically for forming flat ends of rubber hoses, filling the technical gap in the prior art where there is a lack of tooling for directly producing flat ends of rubber hoses. By setting a pipe-cutting fixture with countersunk holes and flat end slots, and in conjunction with the cutting action of a cutter, the end of the rubber hose can be directly processed into a flat end shape, solving the technical problem that the prior art cannot effectively produce flat ends of rubber hoses.
[0021] Second, the device of this utility model has a simple structure and is easy to operate. The tube cutting fixture achieves accurate positioning of the hose through the countersunk hole, and limits the cutting range through the flat end slot. With the help of the cutter, the flat end can be formed. The entire device has a compact structure and clear functions of each component, avoiding complex mechanical transmission and control systems, and greatly simplifying the equipment structure.
[0022] Third, this utility model enables simultaneous forming of both ends of the hose, significantly improving production efficiency. By setting two countersunk holes and corresponding flat end slots on the hose cutting fixture, and cooperating with two cutters working simultaneously, the flat end processing of both ends of the hose can be completed in one go, doubling the efficiency compared to the traditional single-end processing method. The design of the flat end slot width being smaller than the countersunk hole diameter and symmetrical with the center of the countersunk hole ensures the accuracy of the flat end shape. The countersunk hole depth controls the hose positioning depth, and the flat end slot depth determines the height of the material to be cut. This dual dimension control mechanism effectively ensures the consistency of product quality.
[0023] Fourth, this utility model is easy to operate, reducing the skill requirements for operators. Operators only need to insert both ends of the tubing into the countersunk holes to the bottom and start the cutting action to complete the flattening process. No complicated adjustments or settings are required, avoiding the uncertainty of manual operation and facilitating large-scale production. Attached Figure Description

[0032] Example 1
[0033] like Figure 1-4 As shown, this utility model provides a hose flattening forming device, mainly composed of two parts: a hose cutting fixture 101 and a cutter 102. The hose cutting fixture 101 is the core component of the entire device, responsible for positioning the hose 103 and guiding the movement of the cutter 102. The hose cutting fixture 101 has a countersunk hole 1011 inside, which serves to axially position the hose 103, ensuring consistent insertion depth. The diameter of the countersunk hole 1011 should match the outer diameter of the hose 103 to be processed, ensuring smooth insertion of the hose 103 while avoiding excessive gaps that could affect positioning accuracy.
[0034] The tube cutting fixture 101 is equipped with a guide rail 1012, which connects to the countersunk hole 1011 to form a flat-mouth slot 1013. This design cleverly integrates the movement path of the cutter 102 with the forming area. The width of the flat-mouth slot 1013 is designed to be smaller than the diameter of the countersunk hole 1011 (the specific size can be adjusted according to actual needs). This design ensures that when the tube 103 is fully inserted into the countersunk hole 1011, only a portion of the tube material will protrude from the flat-mouth slot 1013, providing a foundation for subsequent tube flat-mouth cutting and forming. The width of the flat-mouth slot 1013 is symmetrically set around the axis of the countersunk hole 1011, ensuring a symmetrical and aesthetically pleasing shape after flat-mouth forming.
[0035] In a preferred embodiment, the tube cutting fixture 101 is provided with two guide rails 1012, each guide rail 1012 having two countersunk holes 1011. This design allows the device to simultaneously flatten both ends of the hose 103, greatly improving processing efficiency. The two guide rails 1012 are positioned opposite each other on both sides of the tube cutting fixture 101, a layout that facilitates operation and also benefits the configuration and movement of the cutter 102. The design of the guide rails 1012 not only provides the cutter 102 with an accurate movement path, but also forms a flattened slot 1013 through communication with the countersunk holes 1011, achieving an integrated structural design.
[0036] The cutter 102 is the component that performs the cutting action. In this invention, the cutter 102 adopts an L-shaped structure, which has good rigidity and cutting performance. A cutting edge 1021 is provided on one side of the L-shaped structure, and the cutting edge 1021 is kept sharp to ensure a clean and crisp cut. The design of the L-shaped cutter 102 allows it to move smoothly along the guide rail 1012 while maintaining a good fit with the flat-mouth slot 1013. The cutter 102 is placed against the guide rail 1012, and moves along the guide rail 1012 under external force. In a specific embodiment of this invention, see [reference needed]. Figure 1 The operator places the cutter 102 against the guide rail 1012, holds the part of the cutter 102 that protrudes from the guide rail 1012 to ensure stability during the driving process, and then drives the cutter 102 to move along the guide rail 1012. This movement mechanism ensures the stability and reproducibility of the cutting trajectory.
[0037] In a preferred embodiment, the device is equipped with two cutters 102, each used to cut off the portion of the two rubber tubes 103 that exposes the corresponding flat-mouth slot 1013. The cutting edge 1021 of the cutter 102 is in close contact with the corresponding guide rail 1012, ensuring the accuracy and consistency of the cutting. The cutter 102 can be moved along the guide rail 1012 by manual operation or automatic drive, depending on production needs. The guiding effect of the guide rail 1012 ensures that the movement path of the cutter 102 always remains within the predetermined cutting area, avoiding the problems of deviation and miscutting.
[0038] The specific working process of this utility model is as follows: First, the two ends of the rubber tube 103 to be processed are respectively inserted into the two countersunk holes 1011 of the tube cutting fixture 101 until the ends of the rubber tube 103 contact the bottom of the countersunk holes 1011, completing the axial positioning. At this time, part of the material of the rubber tube 103 will be exposed through the connection between the guide rail 1012 and the countersunk hole 1011, revealing the flat opening groove 1013. Then, the two cutters 102 are started and move simultaneously along their respective guide rails 1012. Under the guidance of the guide rails 1012, the cutting edges 1021 of the cutters 102 accurately cut off the exposed material of the rubber tube 103. Due to the width limitation and height control of the flat opening groove 1013 formed by the guide rails 1012, the end of the cut rubber tube 103 presents the required flat opening shape.
[0039] During the cutting process, the guide rail 1012 not only provides a precise movement path for the cutter 102, but also forms a flat slot 1013 through its connection with the countersunk hole 1011. This design ensures that the cutter 102 always cuts in the correct position, avoiding problems such as inaccurate cutting position and irregular shape that are common in traditional manual operations. The axial constraint provided by the countersunk hole 1011 ensures that the hose 103 will not shift during the cutting process, and the geometric constraint of the flat slot 1013 guarantees the shape and dimensional accuracy of the flat slot.
[0040] After cutting, the hose 103 is removed from the countersunk hole 1011, resulting in a finished flat hose 1031 with flat ends. Throughout the entire processing, the guide rail 1012 ensures the consistency and precision of the cutting. The operator only needs to control the cutter 102 to move along the guide rail 1012, which greatly reduces the difficulty of operation.
[0041] This invention features an innovative design that connects the guide rail 1012 with the countersunk hole 1011 to form a flat-mouth groove 1013. This design not only precisely defines the forming area but also provides an accurate movement path for the cutter 102. This integrated structural design simplifies the device structure and improves processing accuracy. The device has a compact structure, low manufacturing cost, and is easy to maintain, making it particularly suitable for applications requiring mass production of flat-mouth rubber hoses 1031. This specialized device effectively solves the problem of the lack of existing methods for forming flat-mouth rubber hoses, providing a reliable technical solution for related industries.
[0042] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent transformations or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
