Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of copper pipe manufacturing, in particular to a copper pipe thinning production equipment. BACKGROUND

[0002] Copper pipes usually need to be thinned by drawing process, and thicker copper pipes are drawn into thinner copper pipes. The copper pipe industry for air conditioners and refrigeration shows a trend of high precision and thinness. High precision and thinness lead to an increase in the number of drawing, which affects production efficiency. Therefore, it is a trend to reduce the number of drawing without affecting production efficiency while ensuring high-precision production.

[0003] Because the copper pipe is subjected to multiple drawing processes during the drawing work, the copper pipe is gradually thinned, but this will cause the equipment for processing the pipeline to be usually longer, requiring a larger floor area, and the subsequent maintenance work is very cumbersome, so optimization and improvement are needed. SUMMARY

[0004] In view of the deficiencies of the prior art, the technical scheme adopted by the application to solve the technical problems is: a copper pipe thinning production equipment, comprising:

[0005] a shaping component;

[0006] three drawn copper pipes are uniformly threaded through the shaping component for thinning and drawing process, and the device can process three drawn copper pipes at a time;

[0007] a traction component is symmetrically arranged on the left and right sides of the shaping component and can pull the end of the drawn copper pipe through the shaping component;

[0008] the shaping component comprises:

[0009] a guide shell, an inner cavity of the guide shell is provided with a guide slide rail, and an inner wall of the guide shell is provided with a perforating component through the guide slide rail;

[0011] two outer slide covers are symmetrically arranged on the upper and lower sides of the outer surface of the guide shell, the external adjuster pulls the outer slide covers on the upper and lower sides to slide by the vertical slide rod, the inner wall of the outer slide cover is fixedly connected with the outer surface of the perforating component through the penetrating connecting rod, and the external adjuster controls the sliding movement of the internal perforating component by pulling the sliding movement of the outer slide cover;

[0012] the perforating component comprises:

[0013] The inner cavity of the first guide block is uniformly provided with a large expansion opening;

[0023] The top end of the pressure push rod is fixedly connected with the inner cavity of the gas pressure outer box, and the outer surface of the pressure push rod is slidably connected with the inner wall of the container plate through the limiting sliding groove. After the gas pressure outer box pressurizes the inside of the pressure push rod, the pressure push rod will be elongated along the limiting sliding groove, thereby realizing the pushing function;

[0024] The back of the connecting counterweight block is slidably connected with the inner wall of the limiting sliding groove, and the bottom end of the pressure push rod is fixedly connected with the back of the outer surface of the connecting counterweight block;

[0025] The lower surface of the connecting counterweight block is fixedly connected with the upper surface of the clamping bottom plate, and the inside of the clamping bottom plate is slidably connected with the outer surface of the gas pressure outer box through the cutout. The connecting counterweight block drives the clamping bottom plate to slide, and since the clamping bottom plate always slides in the vertical direction along the outer surface of the container plate through the back recess, the clamping bottom plate will not deviate.

[0026] Further, the drawn copper pipe comprises:

[0027] The both ends of the ductile copper body are symmetrically provided with traction end heads, the traction end heads are welded at the end head positions of the ductile copper body, and the traction end heads are rollingly connected with embedded balls away from one end of the ductile copper body; when the ductile copper body passes through the guide block from top to bottom, the ductile copper body will pass through three expansion openings and be sequentially reduced in outer diameter under the extrusion to realize the thinning processing work.

[0028] The lower surfaces of the connecting counterweights are uniformly provided with adaptive grooves, and the inner walls of the adaptive grooves are complementary to the outer surfaces of the traction end heads.

[0029] Further, the copper pipe thinning production equipment further comprises:

[0030] The outer frame is symmetrically provided with buffer limiting plates on the upper and lower sides of the middle part of the inner wall.

[0031] The auxiliary components are symmetrically arranged on the left and right sides of the inner wall of the outer frame.

[0032] The outer surface of the fixed traction cylinder is fixedly connected with the inner wall of the outer frame, and the outer surface of the outer adjustment device is fixedly connected with a stable connecting frame, and the bottom end of the stable connecting frame is fixedly connected with the bottom of the inner wall of the outer frame.

[0033] Further, the auxiliary components comprise:

[0034] The outer surface of the fixed box shell is fixedly connected with the inner wall of the outer frame.

[0035] The bottom of the inner cavity of the drainage plate is uniformly provided with a plug-in inner plate, and the inner part of the drainage plate is added with cooling liquid, so that the drainage plate can play a drainage role on the cooling liquid and accelerate heat dissipation of the cooling liquid.

[0036] The sliding outer plate is a vertical plate shell with an inner cavity, the inner wall of the sliding outer plate is slidingly connected with the outer surface of the plug-in inner plate, the outer surface of the sliding outer plate is slidingly connected with the inner wall of the fixed box shell, both sides of the outer surface of the sliding outer plate are symmetrically provided with wall-attached roller shafts through cutout openings, and both ends of the wall-attached roller shafts are provided with control motors, the outer surface of the control motor is fixedly connected with the inner cavity of the sliding outer plate, and the outer surface of the wall-attached roller shaft is rollingly connected with the inner wall of the fixed box shell.

[0037] The outer surface of the arc-shaped pressing plate is fixedly connected with the bottom end of the sliding outer plate.

[0038] The beneficial effects of the present application are as follows:

[0039] 1. The device can drive the drawn copper pipe through the expansion opening of the guide block through the traction components on both sides, so that the drawn copper body is extruded and deformed, thereby realizing the fine drawing of the copper pipe. Since the moving track of the drawn copper pipe is always located at the axial position of the device, and the drawn copper pipe moves back and forth during processing, the overall moving track of the drawn copper pipe is greatly shortened, the device occupies a small area, and the perforating component through which the pipe passes is always located inside the shaping component, so that concentrated detection work can be carried out on the internal perforating component during maintenance and detection work, ensuring that the outer diameter of the drawn copper pipe after fine drawing meets the size, and optimizing the detection work.

[0040] 2. The perforating component is composed of three groups of guide blocks from top to bottom. Since the drawn copper pipe cannot be processed to meet the required size in one step during fine drawing, the drawn copper pipe needs to pass through three different expansion openings from top to bottom, so as to gradually realize the effect of fine drawing of the drawn copper pipe, thereby avoiding the problem that the drawn copper pipe is severely extruded and deformed when passing through a smaller expansion opening, thereby causing the end part to be pulled too hard and broken.

[0041] 3. The device is modified for the drawn copper pipe, and traction end heads are welded at both ends of the drawn copper pipe that needs to be fine drawn. Since the traction end head is thin and has high hardness, it will not be obviously deformed due to excessive extrusion force, so it can provide a stable clamping point for the traction component, thereby avoiding the problem that the end part of the drawn copper body is clamped and deformed when the traction component directly clamps the drawn copper body, causing the drawn copper body to fail to pass through the expansion opening smoothly. The traction end head and the combined adaptive groove are complementary, ensuring that the drawn copper pipe will not slip during the clamping and fine drawing process.

[0042] 4. Since a large amount of heat is generated during the extrusion and deformation of the drawn copper body passing through the expansion opening, the drainage plate at the top will inject cooling liquid into the internal position of the sliding outer plate through the plug-in inner plate when the arc-shaped pressing plate contacts the drawn copper body, so that the arc-shaped pressing plate absorbs the heat of the drawn copper body, achieving cooling effect, and avoiding the problem of thermal fusion deformation of the arc-shaped pressing plate due to contact with the high-temperature drawn copper body.

[0053] Embodiment 1, please refer to Figures 1-5 The present application provides a technical solution: a copper pipe thinning production equipment, comprising:

[0054] The shaping component 2;

[0055] The drawing copper pipe 3 is three in number, and is uniformly passed through the shaping component 2 for thinning drawing processing. The device can process three drawing copper pipes 3 at a time;

[0060] An outer slide cover 23, the number of the outer slide cover 23 is two, which are symmetrically arranged on the upper and lower sides of the outer surface of the guide shell 21, and the outer slide cover 23 is moved by the vertical slide rod dragging the outer slide cover 23 on the upper and lower sides, the inner wall of the outer slide cover 23 is fixedly connected with the outer surface of the perforated part 6 through the penetrating connecting rod 25, and the external adjuster 22 controls the sliding movement of the internal perforated part 6 by sliding the outer slide cover 23;

[0061] The perforated part 6 comprises:

[0062] A first guide block 61, the inner cavity of the first guide block 61 is uniformly provided with a large expansion opening;

[0063] A second guide block 62, the inner cavity of the second guide block 62 is uniformly provided with a medium expansion opening;

[0064] A third guide block 63, the inner cavity of the third guide block 63 is uniformly provided with a small expansion opening;

[0065] The three guide blocks are sequentially stacked from top to bottom to form an integral plate, and can slide up and down along the guide rail of the inner wall of the guide shell 21 under the dragging action of the penetrating connecting rod 25 on the upper and lower sides.

[0066] The traction part 4 comprises:

[0067] A container plate 41, limit slide grooves 42 are symmetrically arranged on the upper and lower sides of the inner cavity of the container plate 41;

[0068] A fixed traction cylinder 44, the inner wall of the fixed traction cylinder 44 is slidably connected with a thick connecting rod 43, and the end of the thick connecting rod 43 away from the fixed traction cylinder 44 is fixedly connected with the outer surface of the container plate 41;

[0069] A pressing part 45, which is symmetrically arranged on the upper and lower sides of the container plate 41, is used for clamping the end part of the drawn copper pipe 3.

[0070] The pressing part 45 comprises:

[0071] A gas pressure outer box 451, the outer surface of the gas pressure outer box 451 is fixedly connected with the outer surface of the container plate 41;

[0072] The pressure push rod 452 is fixedly connected with the inner cavity of the air pressure outer box 451 at the top end, and the outer surface of the pressure push rod 452 is slidably connected with the inner wall of the container plate 41 through the limiting sliding groove 42. After the air pressure outer box 451 pressurizes the inside of the pressure push rod 452, the pressure push rod 452 will be elongated along the limiting sliding groove 42, thereby realizing the pushing function.

[0073] The connecting counterweight 453 is slidably connected with the inner wall of the limiting sliding groove 42 at the back, and the bottom end of the pressure push rod 452 is fixedly connected with the back of the outer surface of the connecting counterweight 453.

[0074] The clamping bottom plate 454 is fixedly connected with the upper surface of the clamping bottom plate 454 at the lower surface of the connecting counterweight 453, and the inner part of the clamping bottom plate 454 is slidably connected with the outer surface of the air pressure outer box 451 through the cutting groove. The connecting counterweight 453 drives the clamping bottom plate 454 to slide, and since the clamping bottom plate 454 always slides in the vertical direction along the outer surface of the container plate 41 through the back groove, the clamping bottom plate 454 will not deviate.

[0075] First, the copper pipe to be processed is welded with a traction end head 32 at both ends, and the traction end head 32 is clamped to drive the extended copper body 31 to be thinned.

[0076] Before the first thinning work, the external adjuster 22 on both sides first moves the first guide block 61 to the middle position of the guide shell 21 by pulling the outer sliding cover 23, that is, the perforating part 6 shown in the figure is moved downward, and at this time, the first guide block 61 is located at the middle position of the guide shell 21. Figure 3

[0077] First, the left end of the extended copper body 31 is clamped by the left traction part 4, that is, the left traction end head 32 is fixed by the clamping bottom plate 454 clamped on both sides, and then the right end of the drawn copper pipe 3 is inserted into the large expansion opening of the first guide block 61 by the left fixed traction cylinder 44 through the pushing coarse connecting rod 43. Since the traction end head 32 is thin, the traction end head 32 at the right end can pass through the large expansion opening, and then the right traction part 4 clamps the traction end head 32 at the right end, and cooperates with the pushing action of the left traction part 4 to pull out the drawn copper pipe 3 from the left to the right of the large expansion opening. The extended copper body 31 is extruded during passing through the large expansion opening, thereby reducing the outer diameter, and completing the initial thinning process.

[0078] ​After the drawing copper pipe 3 passes through the large expansion opening, the traction part 4 on the left end releases the clamped traction end head 32, so that the drawing copper pipe 3 completely passes through the large expansion opening, and then the external adjuster 22 on the two sides moves the second guide block 62 to the middle part of the guide shell 21 by pulling the outer sliding cover 23 upwards, so that the traction end head 32 on the left end of the drawing copper pipe 3 can slide relative to the outer surface of the plate body of the perforating part 6, and then is inserted into the inside of the middle expansion opening from right to left, and then the drawing copper pipe 3 passes through the middle expansion opening by the above-mentioned mode and the traction part 4 on the left end, so that the secondary thinning processing is completed.

[0079] Finally, the external adjuster 22 on the two sides moves the third guide block 63 to the middle part of the guide shell 21 by traction, and the drawing copper pipe 3 passes through the small expansion opening by the similar thinning processing mode, so that the final thinning processing is completed, and the outer diameter of the drawn copper body 31 meets the production requirements.

[0080] After the thinning drawing copper pipe 3 is removed, the traction end head 32 at both ends is cut off, the drawn copper body 31 after the middle thinning is obtained, the traction end head 32 is welded to the drawn copper body 31 which needs to be thinned next time, and the effect of recycling is realized.

[0081] Embodiment 2, please refer to Figures 1-8 The present application provides a technical solution: on the basis of embodiment 1, the drawing copper pipe 3 comprises:

[0082] The drawn copper body 31 is provided with the traction end head 32 at both ends in a symmetrical manner, the traction end head 32 is welded at the end head position of the drawn copper body 31, the end of the traction end head 32 away from the drawn copper body 31 is connected with the embedded ball in a rolling manner, and when the drawn copper body 31 passes through the guide block from top to bottom, the drawn copper body 31 will pass through three expansion openings and be reduced in outer diameter under the extrusion to realize the thinning processing work;

[0083] The lower surface of the connecting counterweight block 453 is uniformly provided with the adaptive groove 455, and the inner wall of the adaptive groove 455 is complementary to the outer surface of the traction end head 32, so that the traction end head 32 is clamped by the adaptive groove 455.

[0084] The copper pipe thinning production equipment further comprises:

[0085] The external frame 1 is provided with the buffer limiting plate 26 on the inner wall of the external frame 1 in a symmetrical manner on the upper and lower sides of the middle part.

[0086] The auxiliary part 5 is provided on the left and right sides of the inner wall of the external frame 1 in a symmetrical manner.

[0087] The outer surface of the fixed traction cylinder 44 is fixedly connected with the inner wall of the external frame 1, and the outer surface of the external adjuster 22 is fixedly connected with the stable connecting frame 24, and the bottom end of the stable connecting frame 24 is fixedly connected with the bottom of the inner wall of the external frame 1.

[0088] The auxiliary component 5 comprises:

[0089] The fixed box shell 51 is fixedly connected with the inner wall of the external frame 1;

[0090] The drainage plate 52 is internally provided with the plug-in inner plate 53, and the inside of the drainage plate 52 is added with the cooling liquid, so that the drainage plate 52 can play a role in draining the cooling liquid and accelerating heat dissipation of the cooling liquid;

[0091] The sliding outer plate 54 is a vertical plate shell with an internal hollow, the inner wall of the sliding outer plate 54 is slidingly connected with the outer surface of the plug-in inner plate 53, the outer surface of the sliding outer plate 54 is slidingly connected with the inner wall of the fixed box shell 51, and the outer surface of the sliding outer plate 54 is symmetrically provided with the wall-attached roller shaft 56 through a cut slot on both sides, and the two ends of the wall-attached roller shaft 56 are provided with the control motor 57, the outer surface of the control motor 57 is fixedly connected with the inner cavity of the sliding outer plate 54, and the outer surface of the wall-attached roller shaft 56 is rollingly connected with the inner wall of the fixed box shell 51.

[0092] The arc-shaped pressing plate 55 is fixedly connected with the bottom end of the sliding outer plate 54.

[0093] When the clamping traction end head 32 is clamped, the air pressure outer box 451 on both sides will push the pressure push rod 452 to expand and elongate by pressurizing the pressure push rod 452, so that the connecting counterweight block 453 and the clamping bottom plate 454 are pushed to move to the middle area of the assembly plate 41, at this time, the upper and lower adaptive grooves 455 on both sides are combined to clamp the traction end head 32, and the effect of clamping the drawn copper pipe 3 is realized.

[0094] In the process of drawing the drawn copper pipe 3, as the drawn copper body 31 gradually thins, its length will become longer, and its anti-bending ability will also decrease, so when the drawn copper pipe 3 passes through the expansion opening and the lateral traction component 4 is loosened, the center of gravity of the drawn copper pipe 3 is unbalanced, and the unbalanced end will be bent towards the ground due to gravity, so the auxiliary component 5 is needed to avoid this situation.

[0095] In the process of the drawn copper pipe 3 passing through the expansion opening, corresponding to the auxiliary component 5 on one side, the wall-attached roller shaft 56 on both sides of the sliding outer plate 54 will slide outward along the inner wall of the fixed box shell 51, so as to push the arc-shaped pressing plate 55 to move to a position close to the outer surface of the drawn copper body 31, and the arc-shaped pressing plates 55 on the upper and lower sides support the unbalanced end of the drawn copper body 31, so as to ensure that the drawn copper pipe 3 can normally slide horizontally.

[0096] Since a large amount of heat is generated in the extrusion deformation of the copper body 31 through the expansion opening, the top drainage plate 52 injects cooling liquid into the inner position of the sliding outer plate 54 through the plug-in inner plate 53 in the process of the arc-shaped pressing plate 55 contacting the copper body 31, so that the arc-shaped pressing plate 55 absorbs the heat of the copper body 31 to achieve the cooling effect, and the problem of thermal melting deformation of the arc-shaped pressing plate 55 due to contact with the high-temperature copper body 31 is avoided.

[0097] Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art and related fields without creative labor should belong to the protection scope of the present application. The structures, devices and operation methods not specifically described and explained in the present application are implemented according to the conventional means in the art, unless otherwise specified and limited.
