Description

Technical Field

[0001] The utility model relates to a blanking device for thin copper tubes and soft copper tubes, belonging to the technical field of machining. Background Art

[0002] In the air-conditioning industry, copper tubes are indispensable materials, usually divided into straight copper tubes and coiled copper tubes. Before use, the straight copper tubes need to be cut into specific lengths according to requirements and further processed to form the required parts. However, there are some problems in dealing with soft thin-walled copper tubes in the prior art, such as difficult to stably clamp, easy to deviate during the cutting process, and the copper tubes are easy to be flattened under high-pressure clamping.

[0003] To solve these problems, many attempts and innovations have been made in the industry. For example, in a Chinese utility model with the patent number ZL202320283869.6, a copper tube blanking machine is disclosed. The device includes a frame, a cutting tool, a fixed clamp seat and a tube feeding clamp seat. Both the tube feeding clamp seat and the fixed clamp seat are equipped with V-shaped grooves and liftable pressing plates to accommodate and clamp multiple copper tubes. The tube feeding clamp seat can linearly move along the tube feeding direction to achieve high-precision feeding of the copper tubes.

[0004] Although the above technical solution can realize the simultaneous blanking of multiple copper tubes and improve the feeding accuracy, it does not solve the problem that the soft copper tubes are flattened due to improper clamping during the cutting process. Therefore, such copper tube processing technologies still need further innovation and improvement to ensure the integrity and accuracy of the copper tube structure during processing. Summary of the Invention

[0005] The technical problem to be solved by the utility model is to provide a blanking device for thin copper tubes and soft copper tubes.

[0006] To achieve the above technical purpose, the utility model adopts the following technical solutions:

[0030] The technical content of the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] As Figure 1 and Figure 4 shown, an embodiment of the present utility model discloses a blanking device for thin copper tubes and soft copper tubes, including a base 1, a linear sliding module 2, a non-destructive fixture module 3, a transmission module 4, and a saw blade 5. Among them, the base 1 is a frame structure, composed of a bottom plate 11, side plates 12, and sliding rods 13. The bottom plate 11 is provided with a plurality of parallel and equidistant (the spacing can also be unequal) cutting grooves 111 extending along the length direction of the bottom plate. The side plates 12 are vertically installed at both ends of the bottom plate 11 to support two parallel sliding rods 13, and the sliding rods 13 are in the same direction as the extension direction of the cutting grooves 111.

[0032] The linear sliding module 2 consists of a slider 22, a motor base 23, and a connecting plate 24. The slider 22 is installed below the motor base 23 and is used to slide on the sliding rod 13. The connecting plate 24 is arranged between the motor base 23 and the bottom plate 11, with its top end fixedly connected to the motor base 23, and a saw blade 5 extends downward from its bottom end. This structure can ensure that the motor base 23 and the connecting plate 24 can follow the slider 22 to perform synchronous horizontal linear sliding along the sliding rod 13.

[0033] The non-destructive fixture module 3 consists of a mounting plate 31 and a clamping block 32. The mounting plate 31 is arranged above the cutting groove 111 on the bottom plate 11 and is fixed to the bottom plate 11 by bolts or the like. The clamping block 32 is made of nylon material, has good toughness and high mechanical strength, and is arranged at the bottom of the mounting plate 31, facing the cutting groove 111. The clamping block 32 is axially provided with a plurality of clamping grooves 320 of different sizes along the copper tube. As Figure 2 and Figure 3 shown, these clamping grooves 320 are V-shaped, and their extending direction is perpendicular to the cutting groove 111 and is used to clamp the copper tube 100. More preferably, each of the clamping grooves 320 is set to a different size for respectively clamping copper tubes 100 of different pipe diameters. For example, Figure 2 as shown is using one clamping groove 320 to clamp a thick copper tube 100; Figure 3 as shown is using another clamping groove 320 to clamp a thin copper tube 100. Therefore, the thin copper tube and soft copper tube blanking device provided by the present utility model can be suitable for processing copper tubes of different thicknesses.

[0034] The setting of the clamping grooves 320 allows the clamping grooves 320 of the same size to be in a group, and the sizes of the clamping grooves 320 in different groups are different. These clamping grooves 320 of the same size are arranged perpendicular to the cutting groove 111 (that is, arranged along the direction perpendicular to the rotation axis of the saw blade), and are aligned so that the clamping grooves 320 of the same size can simultaneously clamp the copper tube 100 placed in the direction perpendicular to the cutting groove 111.

[0035] The cutting groove 111 and the clamping groove 320 are parallel and offset, that is, one cutting groove 111 is located between two adjacent clamping grooves. In other words, the clamping groove and any one cutting groove will not be vertically aligned. More preferably, the distance between adjacent cutting grooves 111 is equal to the distance between adjacent clamping grooves 320. Such an offset design realizes uniform force on the upper and lower two surfaces of the copper tube; and because the force area increases, the pressure becomes smaller. In this way, the same copper tube 100 is clamped by a plurality of parallel V-shaped grooves at the same time, increasing the contact area and reducing the pressure generated by clamping, which can realize stable clamping of the copper tube and will not deform. In the direction perpendicular to the axial direction of the saw blade 5, the length of the cutting groove 111 is greater than the length of the clamping groove 320 (that is, from the perspective of the projection on the bottom plate 11, the projection area of the clamping groove 320 is within the area of the cutting groove 111).

[0036] Furthermore, since nylon has good toughness, high mechanical strength and other characteristics, the clamping block 32 can ensure that the pressure of the fixture on the copper tube is uniform. During the cutting process, on the premise that the overall clamping force of the copper tube 100 to be cut remains unchanged, the copper tube is not easily deformed. Therefore, the thin copper tube and soft copper tube blanking device provided by the utility model effectively solves the problem of fixture clamping deformation during the cutting of thin-walled copper tubes.

[0037] As Figure 4 shown, the transmission module 4 includes a motor 41, a transmission shaft 42 and a pulley 43, and is used to control the rotation of the saw blade 5 and the synchronous movement of the motor base 23 along the slide rod 13. The saw blade 5 can move back and forth along the slide rod 13 relative to the base 11 together with the transmission module 4 and perform a transverse movement perpendicular to the cutting groove 111, realizing the movement of two degrees of freedom. Moreover, the saw blade 5 can be pulled manually or dragged by a cylinder, so that the bottom of the saw blade 5 can extend into the cutting groove 111 for cutting the copper tube. Such a design can not only meet the cutting of copper tubes with different pipe diameters and different lengths, but also improve the cutting accuracy.

[0038] The saw blade 5 is located on one side of the clamping block 32 and can cut along the surface of the clamping groove 320. Therefore, the side surface of the clamping block 32 plays a guiding role. During the operation, first place the copper tube 100 to be cut in the clamping groove 320, and adjust the height position of the non-destructive fixture module 3 and the cutting position of the copper tube to ensure that the copper tube 100 is fixedly clamped in the clamping groove 320. Then, after starting the motor 41, the motor 41 drives the pulley 43 to rotate, thereby driving the saw blade 5 to rotate. During this process, the rotation direction of the saw blade 5 is opposite to the feeding direction of the copper tube 100 to be cut, that is, the up-milling method is adopted to effectively avoid the deformation of the copper tube and improve the cutting accuracy. The pulling force of the saw blade 5 can be adjusted to ensure that the copper tube does not displace and deform during the whole cutting process, and ensure the cutting quality.

[0039] The nylon material of the clamping block 32 ensures that the pressure of the fixture on the copper tube is uniform. Even when the overall clamping force remains unchanged, the copper tube is not easily deformed during the cutting process. The rotation direction of the saw blade 5 is opposite to the feeding direction of the copper tube 100 to be cut, and this design helps to reduce the deformation of the copper tube during the cutting process. The bottom of the saw blade 5 can extend into the cutting groove 111 for cutting the copper tube, and the side surface of the clamping block 32 plays a guiding role during this process.

[0040] The pulling force of the saw blade 5 can be adjusted according to the thickness of the copper tube wall to ensure that the cutting force of the saw blade 5 on the copper tube is less than the force of the non-destructive fixture module on the copper tube, thus ensuring the stability and cutting quality of the copper tube during the entire cutting process. The saw blade 5 and the transmission module 4 move back and forth relative to the base 11 along the slide rod 13 and also move horizontally perpendicular to the cutting groove 111, realizing two degrees of freedom of movement to meet the requirements of cutting copper tubes with different diameters at different lengths and improving the cutting accuracy.

[0041] In summary, the thin copper tube and soft copper tube blanking device provided by the present utility model can achieve precise clamping and efficient cutting of copper tubes with different diameters. Among them, the non-destructive fixture module is made of nylon material, ensuring uniform force on the copper tube during the cutting process and effectively preventing deformation of the copper tube. The multiple groups of clamping grooves with different sizes on the non-destructive fixture module enable the blanking device to adapt to copper tubes of various diameters, increasing its versatility. The misaligned design of the cutting groove and the clamping groove, as well as the climb milling rotation mode of the saw blade, further improve the cutting accuracy and reduce the deformation of the copper tube during cutting. The cooperation between the saw blade and the transmission module realizes two degrees of freedom of forward and backward movement and horizontal movement, meeting the cutting requirements of copper tubes with different lengths and diameters. The compact structure design makes the blanking device occupy less space and is suitable for use in environments with limited space. In addition, the pulling force of the saw blade is adjustable, ensuring the stability and cutting quality of the copper tube during the entire cutting process, improving production efficiency, while maintaining the stability of the processing process and product quality, and simplifying the subsequent processing technology.

[0042] The above has made a detailed description of the thin copper tube and soft copper tube blanking device provided by the present utility model. For those of ordinary skill in the art, any obvious modification made to it without departing from the essence of the present utility model will constitute an infringement of the patent right of the present invention and will bear corresponding legal responsibilities.
