Description

Technical Field

[0001] The utility model relates to the field of floral tube machines, in particular to a cold-rolling floral tube machine. Background Art

[0002] A patterned tube machine is a device used for cold-rolling patterned metal tubes. Using precise molds and rolling techniques, it can extrude a variety of patterns onto the surface of pipes. It is widely used in construction, home decoration, and other industrial fields. This equipment features high efficiency, a high degree of automation, and high processing precision, meeting the diverse customer requirements for both appearance and performance. The patterned tube machine not only enhances the aesthetics of the product but also increases the added value of the pipe.

This utility model discloses a tubular material knurling machine, including: a base plate, the upper wall of the base plate is installed with a track support structure, the left wall of the track support structure is installed with a power structure, the lower wall of the base plate is installed with a screw structure, a transmission structure is installed between the screw structure and the track support structure, and a printing structure is installed on the outside of the screw structure; the track support structure includes: a track, a movable support frame, a fixed support frame, a movable conical plug, a movable conical plug mounting rod, a bearing, a movable support frame fixing plate, a movable support frame locking bolt and a fixed conical plug; the utility model completes the printing processing of the pipe by setting the track support structure, the power structure, the screw structure, the transmission structure and the printing structure.

[0004] Although the above-mentioned steel pipe knurling machine can fully knurl the steel pipe through the combined action of the track support structure, power structure, screw structure, transmission structure and printing structure, the knurling range of the above-mentioned device is relatively limited, so it will not be able to process longer steel pipes. In addition, the method of relying solely on a spring to pull the printing bending rod so that the printing roller at its end contacts the steel pipe and knurls along with the rolling of the steel pipe is prone to poor knurling effect due to insufficient pressure.

[0005] Therefore, a cold rolling forming flower tube machine is proposed to solve the above problems. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] When implementing: Figures 1-4 As shown, a cold-rolled forming flower tube machine comprises: a bottom plate 1, a support shell 2 is fixedly connected to the surface of the bottom plate 1, and a steel tube body 4 is arranged in the inner cavity of the support shell 2; a knurling assembly 3, and the knurling assembly 3 is arranged on the surface of the bottom plate 1;

[0025] When aligning the steel pipe body 4, if the end of the steel pipe body 4 is hollow, it is necessary to use an object to block the end of the steel pipe body 4 so that the end of the steel pipe body 4 is solid. In this way, the infrared light emitted by the infrared emitter 6 can directly hit the surface of the object, which is beneficial for the staff to align the steel pipe body 4 by coordinating with the edge of the steel pipe body 4. If the end of the steel pipe body 4 is solid, infrared light can be directly used for alignment.

[0026] It should be noted that after the infrared emitter 6 is used to align the steel pipe body 4, the vertical rod 5 needs to drive the infrared emitter 6 to be moved from a vertical position to a parallel position, so as to prevent the discharge of the steel pipe body 4 from being affected after knurling.

[0027] like Figure 1 、 Figure 2 and Figure 3 As shown, the knurling assembly 3 includes a driving shell 301 fixedly connected to the surface of the base plate 1, the surface of the driving shell 301 is fixedly connected to the motor 303, the output end of the motor 303 passes through the inner cavity of the driving shell 301 and is fixedly connected to the first transmission wheel 304, the surface of the first transmission wheel 304 is provided with a transmission belt 305, one side of the inner cavity of the transmission belt 305 is movably connected to the second transmission wheel 306, the inner cavity of the second transmission wheel 306 is movably connected to the cold-rolled knurling wheel 307 through a rotating shaft; three cold-rolled knurling wheels 307 are arranged in an annular array, among which the cold-rolled knurling wheel 307 near the top is inclined, and its angle is twenty degrees; the inner cavity of the driving shell 301 is fixedly connected to the guide rail 302, and the inner cavity of the guide rail 302 is slidably connected to the surface of the second transmission wheel 306; the surface of the cold-rolled knurling wheel 307 is fixedly connected to the push rod 308, and one end of the push rod 308 close to the inner wall of the second transmission wheel 306 is fixedly connected to the inner wall of the second transmission wheel 306;

[0028] First, the motor 303 is turned on, and the output end of the motor 303 rotates the second transmission wheel 306 through the first transmission wheel 304 in cooperation with the transmission belt 305. At this time, the three cold-rolled knurling wheels 307 inside the second transmission wheel 306 will rotate along with the second transmission wheel 306. During rotation, since one of the cold-rolled knurling wheels 307 is tilted and the tilt angle is outward, it can knurl the steel pipe body 4 while also driving the steel pipe body 4 to move outward on its own, achieving the effect of self-feeding and knurling;

[0029] There are three cold-rolled knurling wheels 307, and the effects of the three rolling pulleys 7 are different. The first cold-rolled knurling wheel 307 is generally responsible for applying the basic texture to give the surface of the steel pipe body 4 a preliminary embossing effect. The second cold-rolled knurling wheel 307 is usually used to deepen or refine the texture that has been formed, increase its depth and clarity, and the third cold-rolled knurling wheel 307 is generally used for detail processing and smooth surface to ensure texture consistency and appearance quality. The first cold-rolled knurling wheel 307, that is, the original top cold-rolled knurling wheel 307, will use the friction between its surface and the steel pipe body 4 when rotating around the steel pipe body 4 to promote the self-displacement and rolling of the steel pipe body 4, thereby achieving the effect of continuous feeding and synchronous knurling.

[0030] The inner cavity of the supporting shell 2 is provided with an auxiliary frame 8, and a pulley 7 is provided at the end of the auxiliary frame 8, and the surface of the pulley 7 is in contact with the steel pipe body 4; the inner cavity of the auxiliary frame 8 is fixedly connected to the cylinder 9, and the end of the cylinder 9 close to the supporting shell 2 is fixedly connected to the supporting shell 2; the left side of the base plate 1 is movably connected to the vertical rod 5 through the rotating shaft, and the end of the vertical rod 5 is fixedly connected to the infrared emitter 6;

[0031] It should be noted that the motor 303, the first transmission wheel 304, the transmission belt 305, the second transmission wheel 306, the cold-rolled knurled wheel 307, the push rod 308, the infrared emitter 6 and the cylinder 9 in the above description are all relatively mature devices in the existing technology. The specific models can be selected according to actual needs. At the same time, the power supply of the motor 303, the push rod 308, the infrared emitter 6 and the cylinder 9 can be powered by a built-in power supply or by mains power. The specific power supply method is selected according to the situation and will not be described in detail here.

[0032] When the present invention is in use, when the staff needs to perform knurling on the steel pipe body 4, first the vertical rod 5 is toggled to a vertical position, and then the infrared emitter 6 is turned on to make the infrared emitter 6 emit infrared rays. The emission position of the infrared rays is exactly opposite to the center point of the drive shell 301, that is, the correct placement position of the steel pipe body 4. Then the staff can place the steel pipe body 4 inside the supporting shell 2. At this time, the steel pipe body 4 will be supported on the surface of the two pulleys 7 of the auxiliary frame 8. Then the staff can observe whether the emission point of the infrared rays corresponds to the axis of the steel pipe body 4 to adjust the height of the auxiliary frame 8 through the cylinder 9. When the steel pipe body 4 is aligned, the steel pipe body 4 is inserted into the drive shell 301. Inside the shell 301, the three push rods 308 are opened at the same time, and the three cold-rolled knurling wheels 307 are moved closer to the steel pipe body 4 until they contact the surface of the steel pipe body 4. Then the motor 303 is turned on, and the output end of the motor 303 rotates the second transmission wheel 306 through the first transmission wheel 304 and the transmission belt 305. At this time, the three cold-rolled knurling wheels 307 inside the second transmission wheel 306 will rotate with the second transmission wheel 306. During rotation, since one of the cold-rolled knurling wheels 307 is tilted and the tilt angle is outward, it can knurl the steel pipe body 4 while also driving the steel pipe body 4 to move outward by itself, thereby achieving the effect of self-knurling.

[0033] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
