Description

Technical Field

[0001] The invention specifically relates to the technical field of water divider crimping, in particular to an automatic crimping machine for a water divider. Background Art

[0002] In many fields such as water heating, air conditioning and refrigeration, the connection quality between the manifold and the pipeline is crucial. Traditional connection methods often rely on manual operation, such as using a wrench to tighten the nut. This method is not only inefficient, but also difficult to ensure the tightness and consistency of the connection, which is prone to water leakage, air leakage and other problems, affecting the normal operation of the entire system. With the development of industrial automation, the demand for efficient and accurate manifold and pipeline connection equipment is becoming increasingly urgent.

[0003] At present, when a traditional crimping machine extrude the end of a square tube, it extrudes a crimping die inward, thereby extruding the end of the square tube into a round shape. However, when the traditional crimping machine extrude, the gap between two adjacent crimping dies may cause extrusion marks to be left when the square tube is extruded. This may cause inappropriate dimensions when assembling the pipeline. Moreover, when a traditional crimping machine extrude a steel pipe, there is no supporting structure inside the steel pipe. This may cause serious deformation inside the pipe during crimping. When the pipe is severely deformed, it may affect the working efficiency of the water distributor.

[0004] After searching, Chinese patent application number CN202410646531.1 discloses a crimping machine; including a fixed seat; a piston module, including a first sleeve and a plurality of pressing blocks, wherein one end of the first sleeve along its axial direction is fixedly connected to the fixed seat, and the plurality of pressing blocks are all slidably connected to the other end of the first sleeve along its axial direction along the radial direction of the first sleeve, and the plurality of pressing blocks are evenly arranged around the axis of the first sleeve, and the plurality of pressing blocks have a first working position for enclosing and wrapping the pipe fittings, and a second working position for dispersing and releasing the pipe fittings; a second sleeve, which is sleeved on the outer periphery of the first sleeve and can reciprocate along its axial direction, and the second sleeve can apply a thrust to the plurality of pressing blocks during the forward movement process, so that the plurality of pressing blocks slide from the second working position to the first working position, and the thrust is cancelled when the second sleeve moves in the reverse direction; and a reset member, which can restore the plurality of pressing blocks from the first working position to the second working position after the thrust is cancelled;

[0005] When the crimping machine in the above patent is crimping the steel pipe, the second blocks are driven by the multiple first blocks to shrink inward, so that the end of the square pipe located in the center is squeezed into a circle. However, when the crimping machine in the above patent is crimping, the gap between the two adjacent second blocks cannot effectively ensure that the end of the steel pipe is squeezed into a complete circle, and there may be sharp edges. In this way, when the crimped steel pipes are assembled, leakage may occur between the pipes. When the device in the above patent is crimping, the inside of the pipe cannot be effectively supported, which will cause serious deformation inside the pipe and even affect the working efficiency of the pipe. Summary of the invention

In this structure, a clamping assembly is arranged on the top of the crimping assembly, and the clamping assembly is fixedly mounted on a swivel support plate. The swivel support plate is cooperatively connected with the swivel drive assembly. In this way, when crimping is performed, after one crimping is completed, the crimping die loosens the opening of the steel pipe, drives the swivel support plate through the active gear, and realizes the rotation of the clamping assembly through the swivel support plate, so as to effectively ensure that the edge of the pipe is crimped evenly during the crimping, and no sharp edges or corners will appear. At the same time, a crimping inner support assembly is arranged at the bottom of the crimping assembly. When the clamping cylinder moves downward and a plurality of crimping dies are retracted inward to crimp the pipe, the clamping cylinder presses the first connecting rod downward; the bottom of the first connecting rod pushes one end of the second connecting rod to move, and under the action of the support seat, the other end of the second connecting rod drives the third connecting rod to tilt upward, so as to realize the cooperation between the conical sleeve and the inner support block, thereby effectively realizing the effect of inner support on the end of the steel pipe, thereby ensuring the quality of the crimping of the steel pipe; so as to solve the problems of the above-mentioned background technology.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. When the present invention is used, the square tube is placed between the second clamp and the first clamp. At this time, the bottom of the square tube contacts the placement plate, and the corresponding first clamp frame and the second clamp frame are driven by the oil cylinder to slide toward the center along the guide column, so that the second clamp and the first clamp inside the first clamp frame and the second clamp frame clamp and fix the square tube, and the shrinkage and extrusion molding of the end of the square tube by the pressing mold is realized by the clamping oil cylinder;

[0020] 2. In the present invention, when the clamping cylinder moves downward during the buckling, on the one hand, multiple buckling molds inside are moved toward the edge of the square tube, so that the end of the square tube is squeezed into a round shape. On the other hand, when the clamping cylinder moves downward, the semicircular block at the bottom of the clamping cylinder presses down the first connecting rod through the rotating shaft, and the end of the first connecting rod away from the semicircular block is connected to one end of the second connecting rod through the rotating shaft. When the clamping cylinder is pressed down, the support seat provided at the bottom of the second connecting rod makes the end of the second connecting rod connected to the first connecting rod rotate downward. During the rotation, the rectangular groove provided on the support plate effectively realizes the penetration effect, avoiding interference.

[0021] 3. In the present invention, when the end connected to the first connecting rod rotates downward, the support seat causes the end connected to the third connecting rod to tilt upward, and the end of the third connecting rod away from the second connecting rod is movably connected to the bottom of the conical sleeve. When the third connecting rod moves upward, the conical sleeve slides upward along the support column. During the sliding process, the conical sleeve passes through the circular hole provided on the placement plate, thereby achieving the cooperation between the conical sleeve and the end of the inner support block provided with an inclined surface;

[0022] 4. In the present invention, when the conical sleeve cooperates with the inclined surface at the end of the inner support block, the conical sleeve squeezes the inner support block, so that the inner support block slides forward along the slide rail provided on the placement plate through the slide groove. In the process of the inner support block sliding forward, the arc-shaped surface of the inner support block contacts the inner wall of the square tube, thereby effectively achieving the inner support effect when the square tube is buckled;

[0023] 5. In the present invention, after the crimping die is crimped, the clamping cylinder drives the crimping die to reset, and the clamping cylinder moves upward. At this time, the semicircular block pulls the first connecting rod, so that the lowered end of the second connecting rod moves upward again, so that the upward end moves downward, thereby realizing the separation between the tapered sleeve and the inner support block through the third connecting rod. In order to ensure that the arc surface of the inner support block is completely separated from the inner wall of the square tube, springs are arranged on both sides of the inner support block to ensure the reset of the inner support block after the inner support is completed;

[0024] 6. According to the present invention, after a crimping is completed, the clamping cylinder drives the crimping mold to separate from the square tube, and then the driving motor drives the active gear to realize the rotation of the swivel support plate along the slip ring on the top of the box body. When the swivel support plate rotates, the clamping assembly installed on the swivel support plate rotates synchronously as a whole, so as to effectively adjust the crimping angle of the square tube. After multiple adjustments and crimping, the processing quality and efficiency of the square tube are effectively guaranteed. After the crimping is completed, the first clamping frame and the second clamping frame drive the corresponding second clamp and the first clamp to separate from the square tube through the cylinder.

[0043] Mounting blocks 615 are fixedly installed on both sides of the inner support block 611; mounting blocks 615 are also arranged on both side walls of the through slots 63; springs 614 are arranged between the mounting blocks 615 on the inner support block 611 and the mounting blocks 615 on the side walls of the through slots 63;

[0044] The fixing sleeve 60 is fixedly mounted on the supporting plate 62 via the supporting column 69 ; a circular hole 616 is provided between the placing plate 61 at the bottom of the fixing sleeve 60 and the supporting column 69 for the conical sleeve 610 to pass through; the conical sleeve 610 is slidably mounted on the supporting column 69 .

[0045] By adopting the above technical solution, when in use, the square tube is placed between the second clamp 35 and the first clamp 36, at which time the bottom of the square tube contacts the placement plate 61, and the corresponding first clamp frame 33 and second clamp frame 34 are driven by the oil cylinder 31 to slide toward the center along the guide column 32, so that the second clamp 35 and the first clamp 36 inside the first clamp frame 33 and the second clamp frame 34 clamp and fix the square tube, and the clamping die 42 is squeezed and formed on the end of the square tube by the clamping oil cylinder 41;

[0046] See also Figure 5-14The inner support block 611 has one end close to the support column 69 and is provided with an inclined surface; the other end is provided with an arc surface; the inner support block 611 has one end with an inclined surface which passes through the through groove 63 and is located inside the fixed sleeve 60.

[0047] In this embodiment, a plurality of third connecting rods 68 are movably mounted at the bottom of the tapered sleeve 610; a second connecting rod 66 is movably mounted at one end of the plurality of third connecting rods 68 away from the tapered sleeve 610 through a rotating shaft; a plurality of the middle bottoms of the second connecting rods 66 are movably connected to a support seat 67 through a rotating shaft; an end of the second connecting rod 66 away from the third connecting rod 68 is connected to the first connecting rod 65 through a rotating shaft; an end of the first connecting rod 65 away from the second connecting rod 66 is movably connected to the semicircular block 43 at the bottom of the clamping cylinder 41 through a rotating shaft;

[0048] By adopting the above technical solution, when the clamping cylinder 41 moves downward during the buckling, on the one hand, the multiple buckling molds 42 inside are moved toward the edge of the square tube, so that the end of the square tube is squeezed into a round shape. On the other hand, when the clamping cylinder 41 moves downward, the semicircular block 43 at the bottom of the clamping cylinder 41 presses down the first connecting rod 65 through the rotating shaft, and the end of the first connecting rod 65 away from the semicircular block 43 is connected to one end of the second connecting rod 66 through the rotating shaft. When the clamping cylinder 41 is pressed down, the support seat 67 provided at the bottom of the second connecting rod 66 makes the end of the second connecting rod 66 connected to the first connecting rod 65 rotate downward. During the rotation, the rectangular groove 64 provided on the support plate 62 effectively realizes the penetration effect, avoiding interference.

[0049] Furthermore, when the end connected to the second link 66 and the first link 65 rotates downward, the support seat 67 causes the end connected to the second link 66 and the third link 68 to tilt upward, and the end of the third link 68 away from the second link 66 is movably connected to the bottom of the tapered sleeve 610. When the third link 68 moves upward, the tapered sleeve 610 slides upward along the support column 69. During the sliding process, the tapered sleeve 610 passes through the circular hole 616 provided on the placement plate 61, so that the tapered sleeve 610 is matched with the end of the inner support block 611 which is set at an inclined surface.

[0050] See also Figure 1-12 In this embodiment, the bottom of the support seat 67 is fixedly mounted on the support plate 62; a rectangular groove 64 is provided on the support plate 62; the rectangular groove 64 is provided on the side of the support seat 67 away from the support column 69, and the length of the rectangular groove 64 is greater than the length from the support seat 67 to the end of the second connecting rod 66 connected to the first connecting rod 65;

[0051] The clamping assembly 3 is installed on the top of the crimping assembly 4; the clamping assembly 3 includes two symmetrical fixing blocks 30; the fixing blocks 30 are fixedly installed with oil cylinders 31; the two symmetrical oil cylinder 31 push rods are respectively fixedly installed with a first clamping frame 33 and a second clamping frame 34, wherein the first clamping frame 33 and the second clamping frame 34 are fixedly installed with a first clamp 36 and a second clamp 35; the first clamp 36 and the second clamp 35 are L-shaped; the first clamp 36 and the second clamp 35 are slot-shaped when matched; the slot groove formed by the first clamp 36 and the second clamp 35 is coaxially arranged with the crimping mold 42;

[0052] By adopting the above technical solution, when the conical sleeve 610 cooperates with the inclined surface at the end of the inner support block 611, the conical sleeve 610 squeezes the inner support block 611, so that the inner support block 611 slides forward along the slide rail 612 provided on the placement plate 61 through the slide groove 613. In the process of the inner support block 611 sliding forward, the arc-shaped surface of the inner support block 611 contacts the inner wall of the square tube, thereby effectively achieving the inner support effect when the square tube is buckled;

[0053] Furthermore, after the crimping die 42 is crimped, the clamping cylinder 41 drives the crimping die 42 to reset, and the clamping cylinder 41 moves upward. At this time, the semicircular block 43 pulls the first connecting rod 65, so that the lowered end of the second connecting rod 66 moves upward again, so that the upward end moves downward, thereby realizing the separation between the tapered sleeve 610 and the inner support block 611 through the third connecting rod 68. In order to ensure that the arc surface of the inner support block 611 is completely separated from the inner wall of the square tube, springs 614 are provided on both sides of the inner support block 611. After the inner support is completed, the reset of the inner support block 611 is ensured;

[0054] See also Figure 1-14 A guide column 32 is also fixedly installed between the two fixed blocks 30; the guide column 32 is located on both sides of the cylinder 31, and the first clamping frame 33 and the second clamping frame 34 are slidably connected to the guide column 32;

[0055] The bottom of the fixed block 30 is fixedly mounted on the slewing support plate 2 by bolts; the bottom of the slewing support plate 2 is slidably connected with the slip ring 7 provided on the housing 1; the edge of the slewing support plate 2 is cooperatively connected with the slewing drive assembly 5; the slewing drive assembly 5 includes a driving gear 50; the driving gear 50 is meshedly connected with the teeth at the edge of the slewing support plate 2; the driving gear 50 is fixedly mounted on the output shaft of the driving motor 51; the driving motor 51 is fixedly mounted inside the housing 1;

[0056] By adopting the above technical solution, after one crimping is completed, the clamping cylinder 41 drives the crimping mold 42 to separate from the square tube, and the driving motor 51 drives the active gear 50 to realize the rotation of the swivel support plate 2 along the slip ring 7 on the top of the box body 1. When the swivel support plate 2 rotates, the clamping assembly 3 installed on the swivel support plate 2 rotates synchronously as a whole, so as to effectively adjust the crimping angle of the square tube. After multiple adjustments and crimping, the processing quality and efficiency of the square tube are effectively guaranteed. After the crimping is completed, the first clamping frame 33 and the second clamping frame 34 drive the corresponding second clamp 35 and the first clamp 36 to separate from the square tube through the cylinder 31.

[0057] The working principle of the present invention is as follows: when in use, the square tube is placed between the second clamp 35 and the first clamp 36, at which time the bottom of the square tube contacts the placement plate 61, and the corresponding first clamp frame 33 and second clamp frame 34 are driven by the oil cylinder 31 to slide toward the center along the guide column 32, so that the second clamp 35 and the first clamp 36 inside the first clamp frame 33 and the second clamp frame 34 clamp and fix the other tube, and the clamping die 42 is contracted and extruded to form the end of the other tube by the clamping oil cylinder 41;

[0058] During the crimping process, when the clamping cylinder 41 moves downward, on the one hand, the multiple crimping dies 42 inside are moved toward the edge of the square tube, so that the end of the square tube is squeezed into a round shape. On the other hand, when the clamping cylinder 41 moves downward, the semicircular block 43 at the bottom of the clamping cylinder 41 presses down the first connecting rod 65 through the rotating shaft. The end of the first connecting rod 65 away from the semicircular block 43 is connected to one end of the second connecting rod 66 through the rotating shaft. When the clamping cylinder 41 is pressed downward, the support seat 67 provided at the bottom of the second connecting rod 66 makes the end of the second connecting rod 66 connected to the first connecting rod 65 rotate downward. During the rotation, the rectangular groove 64 provided on the support plate 62 effectively realizes the penetration effect to avoid interference.

[0059] When the end connected to the second link 66 and the first link 65 rotates downward, the support seat 67 causes the end connected to the second link 66 and the third link 68 to tilt upward, and the end of the third link 68 away from the second link 66 is movably connected to the bottom of the conical sleeve 610. When the third link 68 moves upward, the conical sleeve 610 slides upward along the support column 69. During the sliding process, the conical sleeve 610 passes through the circular hole 616 opened on the placement plate 61, so that the conical sleeve 610 is matched with the end of the inner support block 611 set at an inclined surface;

[0060] When the tapered sleeve 610 cooperates with the inclined surface at the end of the inner support block 611, the tapered sleeve 610 squeezes the inner support block 611, so that the inner support block 611 slides forward along the slide rail 612 provided on the placement plate 61 through the slide groove 613. During the process of the inner support block 611 sliding forward, the arc-shaped surface of the inner support block 611 contacts the inner wall of the square tube, thereby effectively achieving the inner support effect when the square tube is buckled;

[0061] After the crimping die 42 is crimped, the clamping cylinder 41 drives the crimping die 42 to reset, and the clamping cylinder 41 moves upward. At this time, the semicircular block 43 pulls the first connecting rod 65, so that the lowered end of the second connecting rod 66 moves upward again, so that the upward end moves downward, thereby realizing the separation between the conical sleeve 610 and the inner support block 611 through the third connecting rod 68. In order to ensure that the arc surface of the inner support block 611 is completely separated from the inner wall of the square tube, springs 614 are arranged on both sides of the inner support block 611 to ensure the reset of the inner support block 611 after the inner support is completed.

[0062] After one crimping is completed, the clamping cylinder 41 drives the crimping mold 42 to separate from the square tube, and then drives the driving gear 50 through the driving motor 51 to realize the rotation of the swivel support plate 2 along the slip ring 7 on the top of the box body 1. When the swivel support plate 2 rotates, the clamping assembly 3 installed on the swivel support plate 2 rotates synchronously as a whole, so as to effectively adjust the crimping angle of the square tube. After multiple adjustments and crimping, the processing quality and efficiency of the square tube are effectively guaranteed. After the crimping is completed, the first clamping frame 33 and the second clamping frame 34 drive the corresponding second clamp 35 and the first clamp 36 to separate from the square tube through the cylinder 31.
