Description

Technical Field

[0001] This utility model relates to the field of copper tube processing technology, and in particular to a copper tube drawing machine. Background Technology

[0002] Copper tube drawing is a plastic forming process that applies tension to a copper tube using a drawing die, forcing it through the die's orifice to reduce its cross-section and extend its length. This process is widely used in refrigeration and air conditioning, building piping, and machinery manufacturing, and can produce high-precision copper tubes with high surface quality. Depending on the drawing method, die structure, and the state of the copper tube, it is mainly divided into two types: drawing without a mandrel, where the outer diameter of the copper tube is reduced only by the die while the wall thickness remains essentially unchanged; and drawing with a slight reduction in wall thickness, where the mandrel is fixed to a tie rod and the copper tube passes through the annular gap between the die and the mandrel, simultaneously reducing both the outer diameter and wall thickness. There is also a floating mandrel drawing process, where the mandrel has no fixed tie rod and relies on the friction between the die's conical surface and the inner wall of the copper tube to maintain its position; this is suitable for long-length, high-volume production. Additionally, it is used for expanding the inner diameter of copper tubes using a die, often for processing special-specification pipes.

[0003] A search revealed Chinese Patent Publication No. CN217095050U, which discloses a copper tube drawing machine, comprising a support plate, a fixed frame, a mold, a heating tube, a moving device, a housing, an auxiliary block, a piston, an anti-slip plate, and a hydraulic device. The top of the support plate is fixedly connected to the bottom of the fixed frame, the inner wall of the fixed frame is fixedly connected to the surface of the mold, the surface of the mold is fixedly connected to the inner wall of the heating tube, the right side of the support plate is fixedly connected to the left side of the moving device, the top of the slider of the moving device is fixedly connected to the bottom of the housing, the left side of the housing is fixedly connected to the right side of the auxiliary block, and the interior of the auxiliary block is sealed to the surface of the piston. This invention processes copper tubes by using a hydraulic device, piston, anti-slip plate, moving device, and mold, and uses a heating tube to heat the copper tube passing through the mold, softening it and facilitating the drawing device to pull it, thus improving the practicality of the drawing device. It can heat the copper tube, thereby facilitating drawing. However, when its internal structure wears down and requires maintenance, special tools are needed to disassemble the entire machine, leading to reduced maintenance efficiency and increased maintenance costs. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a copper tube drawing machine, which aims to improve the problem that when the structure of the copper tube drawing machine is worn and needs maintenance, it is necessary to use special tools to disassemble the whole machine, which leads to reduced maintenance efficiency and increased maintenance costs.

The protective mechanism provides reliable protection for the internal precision structure, preventing interference and damage from external factors. Since the limit plate three is threadedly connected to the moving component, the limit plate three can move precisely in the guide groove, thereby driving the entire rotating plate one and the components connected to it to adjust their positions.

[0012] The fuel injection assembly includes a fuel pump, the bottom of which is connected to the inner wall of the fuel collection tank, the top of which is connected to a liquid storage tank, and the bottom of the liquid storage tank is connected to an arc-shaped pipe with multiple spray holes at the bottom of the arc-shaped pipe.

[0013] Through the above technical solution, the oil pump can draw liquid from the oil tank, let it enter the arc-shaped pipe, and finally spray it from the nozzle onto the outer wall of the copper pipe to lubricate it.

[0014] As a further description of the above technical solution:

[0026] As a further description of the above technical solution:

[0027] The moving component includes a double-ended lead screw, which is threadedly connected to the inner wall of the limiting plate three, and a gear one is fixedly connected to the left end of the double-ended lead screw.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, by pulling the second limiting plate, the locking rod is pulled to compress the spring through the first limiting plate and leave the inner wall of the slot. Then, the pin is pulled outward, and the slider is pulled upward to separate it from the inner wall of the rotating plate and the slide groove. Then, the first rotating plate is rotated along the third limiting plate to keep it horizontal with the guide groove, thereby removing the guide groove and the structure connected to it from the guide groove.

This achieves the purpose of recovering excess lubricating oil, improves practicality, and reduces production losses. Attached Figure Description

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Please see the appendix Figure 1 - Appendix Figure 3 An embodiment of this utility model is provided: a copper tube drawing machine, including a mounting plate 1, a disassembly mechanism 2 provided on the inner wall of the mounting plate 1, the disassembly mechanism 2 is used to facilitate disassembly and maintenance, a circulation mechanism 3 is fixedly connected to the bottom of the mounting plate 1, the circulation mechanism 3 is used to collect and circulate lubricating oil, a protective mechanism 4 is fixedly connected to the rear side of the mounting plate 1, the protective mechanism 4 is used to protect the internal structure, and a mold 5 is fixedly connected to the top surface of the mounting plate 1 near the edge;

[0041] The disassembly mechanism 2 includes a guide groove 202, which is disposed on the inner wall of the mounting plate 1. Multiple sliding grooves 201 are formed near the edge of the top of the mounting plate 1. A limiting plate 203 is slidably connected to the inner wall of the guide groove 202. The guide groove 202 guides the limiting plate 203 to slide within it. A rotating plate 204 is rotatably connected to the top of the limiting plate 203. Sliding blocks 205 are slidably connected to the left and right sides of the inner wall of the rotating plate 204. A pin 206 is slidably connected to the inner wall of the sliding block 205. The rotating plate 204 is used to support and install the remaining structures. A limiting rod 207 is fixedly connected to the left end of the pin 206. A moving assembly 209 is threadedly connected to the inner wall of the limiting plate 203. A clamping assembly 210 is fixedly connected to the top of the rotating plate 204. The limiting rod 207 limits the position of the pin 206. The left side of the rotating plate 204... A self-locking assembly 208 is fixedly connected. The self-locking assembly 208 includes a hollow block 2085, which is used to support and install the structure related to the self-locking assembly 208. The outer wall of the hollow block 2085 is fixedly connected to the outer wall of the rotating plate 204. A locking rod 2082 is slidably connected to the inner wall of the hollow block 2085. The locking rod 2082 is used to engage with other structures. A limiting plate 2083 is fixedly connected to the outer wall of the locking rod 2082. A limiting plate 2086 is fixedly connected to the adjacent end of the locking rod 2082. The limiting plate 2086 is used to limit the position of the locking rod 2082. A spring 2084 is provided between the adjacent limiting plates 2083 and 2086. A slot 2081 is opened on the inner wall of the pin 206. The spring 2084 is used to push the limiting plate 2083 to reset, thereby driving the locking rod 2082 to slide to reset.

[0042] Specifically, during the sliding process of the pin 206, when it reaches a specific position, the locking lever 2082 automatically engages with the slot 2081 under the elastic force of the spring 2084, thereby locking the pin 206 and ensuring the stability of the clamping assembly 210 during operation. After maintenance or replacement, simply press the locking lever 2082 inward to disengage it from the slot 2081 to release the locking of the pin 206. The limiting plate 2083 limits the sliding stroke of the locking lever 2082, preventing it from sliding out of the hollow block 2085. The spring 2084 is always in a compressed state, providing outward elastic force to the locking lever 2082. The inner wall of the pin 206 has a slot 2081. When the pin 206 slides to a specific position, the locking lever 2082 engages with the slot 2081 under the action of the spring 2084, achieving automatic locking of the pin 206.

[0043] Please see the appendix Figure 2 - Appendix Figure 4The circulation mechanism 3 includes an oil collection tank 301, the top of which is fixedly connected to the bottom of the mounting plate 1. The oil collection tank 301 is used to collect excess liquid. Multiple guide grooves 302 are provided on the top right side of the mounting plate 1. Multiple return holes 303 are provided on the inner wall of the guide grooves 302. The return holes 303 can guide lubricating oil back into the oil collection tank 301. A filter plate 304 is fixedly connected to the inner wall of the return holes 303. An oil spraying assembly 305 communicates with the inner wall of the oil collection tank 301. Component 305 includes an oil pump 3054, which can draw liquid from the oil collection tank 301 and make it flow. The bottom end of the oil pump 3054 is connected to the inner wall of the oil collection tank 301, and the top end of the oil pump 3054 is connected to a liquid storage tank 3053. The liquid storage tank 3053 is used to store the filtered liquid. The bottom of the liquid storage tank 3053 is connected to an arc-shaped pipe 3052. The bottom of the arc-shaped pipe 3052 is provided with multiple spray holes 3051, which can guide lubricating oil to be sprayed on the outer wall of the copper pipe.

[0044] Specifically, as the equipment operates, excess lubricating oil flows down from the top of the mounting plate 1 and into the guide channel 302. Guided by the guide channel 302, the lubricating oil flows to the return hole 303, is filtered by the filter plate 304, and then flows into the oil collection tank 301. When the lubricating oil in the oil collection tank 301 accumulates to a certain amount, the oil pump 3054 starts to extract the lubricating oil from the oil collection tank 301. After being pressurized by the oil pump 3054, the lubricating oil is transported to the storage tank 3053 for further processing and storage. In the storage tank 3053, the lubricating oil undergoes sedimentation and filtration. The clean lubricating oil flows from the storage tank 3053 into the arc-shaped pipe 3052, and is sprayed again onto the outer wall of the copper tube through multiple spray holes 3051 at the bottom of the arc-shaped pipe 3052, providing continuous lubrication support for the copper tube drawing process. This cycle repeats continuously.

[0045] Please see the appendix Figure 3 - Appendix Figure 5 The protective mechanism 4 includes a hollow protective shell 401. The outer wall of the hollow protective shell 401 is fixedly connected to the rear side of the mounting plate 1. The hollow protective shell 401 is used to protect the internal structure. A rotating plate 402 is rotatably connected to the front side of the hollow protective shell 401. A drive mechanism 403 is fixedly connected to the bottom of the inner wall of the hollow protective shell 401. The drive mechanism 403 includes an asynchronous motor 4032. The asynchronous motor 4032 can provide power to the entire drive mechanism 403. The asynchronous motor 4032 is fixedly connected to the bottom of the inner wall of the hollow protective shell 401. A gear 4031 is fixedly connected to the output end of the asynchronous motor 4032. The gear 4031 is used to transmit the power of the asynchronous motor 4032.

[0046] Specifically, the hollow protective shell 401 also has a certain sound insulation and noise reduction function, which can absorb and reflect some noise and reduce the impact of noise on the working environment. During the operation of the copper tube drawing machine, there may be various debris, dust and metal shavings that may be splashed around the equipment. The hollow protective shell 401 can block these potential hazards from entering the equipment and causing damage to the internal structure. The gear 4031, as a power transmission component, can transmit the rotational power generated by the asynchronous motor 4032.

[0047] Please see the appendix Figure 2 - Appendix Figure 4 The moving component 209 includes a double-ended lead screw 2091, which is threadedly connected to the inner wall of the limiting plate 203. The double-ended lead screw 2091 can rotate to drive the limiting plate 203 to move left and right. The left end of the double-ended lead screw 2091 is fixedly connected to a gear 2092. The clamping component 210 includes a hydraulic rod 2101, which can transmit the rotation of the other structures to drive the double-ended lead screw 2091 to rotate. The bottom end of the hydraulic rod 2101 is fixedly connected to the top of the rotating plate 204. The top end of the hydraulic rod 2101 is fixedly connected to a positioning block 2102. The hydraulic rod 2101 can push the positioning block 2102 to move, thereby positioning the copper tube. A limiting groove 2103 is opened in the middle of the top surface of the rotating plate 204. The limiting groove 2103 is used to place the copper tube to be processed.

[0048] Specifically, when positioning the copper tube is required, the power source first drives the gear meshing with gear 2092 to rotate. Gear 2092 transmits power to the double-ended lead screw 2091, causing it to rotate. The rotation of the double-ended lead screw 2091 causes the limiting plate 203 to move left and right, adjusting its position to accommodate the positioning and stretching requirements of copper tubes of different lengths. The hydraulic rod 2101 applies pressure, causing it to extend upwards and push the positioning block 2102 upwards. The positioning block 2102 gradually approaches the copper tube placed in the limiting groove 2103 and makes close contact with the surface of the copper tube, positioning the copper tube from multiple directions.

[0049] Working principle: When stretching the copper tube, it is first inserted into multiple limiting grooves 2103. Then, the hydraulic rod 2101 is activated to pull the positioning block 2102 to clamp the copper tube in the limiting groove 2103. Subsequently, the asynchronous motor 4032 is activated to drive the gear 4031 to rotate, which in turn drives the gear 2092 to drive the double-headed lead screw 2091 to rotate, driving multiple rotating plates 204 to move back and forth, thereby stretching the copper tube. When maintenance is required, the limiting plate 2094 is first pulled. 86 pulls the limiting plate 2083, thereby compressing the spring 2084 and causing the locking rod 2082 to disengage from the slot 2081. Then, the pin 206 is pulled towards the limiting rod 207, thereby removing the slider 205 from the rotating plate 204 and disengaging it from the inner wall of the slide groove 201. Then, the rotating plate 204 is rotated along the limiting plate 203, thereby making it fit against the inner wall of the guide groove 202. Then, the rotating plate 204 and the structure connected to it are removed from the guide groove 202 for maintenance.

[0050] When processing copper tubes, the lubricating oil in the storage tank 3053 is first drawn from the oil collection tank 301 and enters the storage tank 3053. Then, the lubricating oil in the storage tank 3053 flows into the arc-shaped tube 3052 due to gravity and is evenly coated on the outer wall of the copper tube through the spray hole 3051. The excess lubricating oil will flow into the guide groove 302 along the chamfer. After being filtered by the filter plate 304, it flows into the return hole 303 and finally flows back into the oil collection tank 301 for reuse.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing 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. 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.
