Description

Technical Field

[0001] The utility model belongs to the field of mechanical equipment, in particular to a numerically controlled steel pipe slotting machine. Background Art

[0002] The expansion tube needs to be slotted and cut before use. The traditional method is to manually clamp the expansion tube with a tool and then use a special grinding wheel or saw blade to cut 4 or more longitudinal grooves on the expansion tube.

[0049] The preferred embodiment of the utility model is described below in conjunction with the accompanying drawings. It should be understood that the CNC steel pipe slotting machine described here is a preferred embodiment, which is only used to illustrate and explain the utility model and does not constitute a limitation of the utility model.

[0050] The directional terms or positional relationships such as "upper", "lower", "left", "right", "front", and "back" described in the embodiments are based on the figures in the specification of the utility model. Figure 2 , Figure 3 The orientation relationship is only for the convenience of describing the present invention and simplifying the description. It does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the content protected by the present invention.

[0051] like Figures 2 to 19 As shown, this embodiment includes a box body 1 and a feeding mechanism 3, a feeding mechanism 4, a dividing mechanism 2 and a cutting mechanism 5 arranged on the upper surface of the box body 1; the feeding mechanism 3 is arranged between the feeding mechanism 4 and the dividing mechanism 2, and the feeding mechanism 4 can push the steel pipe 10 in the feeding mechanism 3 into the dividing mechanism 2, and then use the cutting mechanism 5 to cut and groove the steel pipe 10.

[0052] 1. Indexing mechanism 2;

[0053] like Figure 6-8 As shown, the dividing mechanism 2 includes a pneumatic clamp 21. The pneumatic clamp 21 adopts the spindle rotating pneumatic clamp in the prior art. The center of the pneumatic clamp 21 has a through hole for the steel pipe 10 to pass through. The pneumatic clamp 21 is provided with a cylinder, which can control the clamp to clamp or loosen the steel pipe 10. Since this part is the prior art, the structure and working principle of the pneumatic clamp 21 will not be described in detail.

[0054] A support 22 is provided between the pneumatic clamping seat 21 and the box body 1 . The support 22 is fixedly arranged on the upper surface of the box body 1 . The pneumatic clamping seat 21 is fixedly arranged on the support 22 . The support 22 plays a supporting role for the pneumatic clamping seat 21 .

[0055] The indexing mechanism 2 also includes a driving component for driving the pneumatic clamping seat 21 to rotate, such as Figure 7 As shown, the driving assembly includes a motor, a synchronous pulley and a synchronous belt. The motor here adopts a servo motor 8 in the prior art. The synchronous pulley includes a driving wheel 23 fixed to the output end of the servo motor 8 and a driven wheel 24 fixedly sleeved on the pneumatic clamp seat 21. The synchronous belt is sleeved on the driving wheel 23 and the driven wheel 24. Figure 7 The synchronous belt is not shown. An electrical control box is provided in the housing 1, and the servo motor 8 is electrically connected to the electrical control box. The servo motor 8 drives the driving wheel 23 and the synchronous belt to rotate, and the synchronous belt drives the driven wheel 24 to rotate, thereby rotating the clamp and the rotating shaft in the pneumatic clamp seat 21, and the steel pipe 10 rotates accordingly, realizing the automatic change of the slot position of the steel pipe 10.

[0056] like Figure 6 , 7 As shown, in this embodiment, the driving assembly is arranged above the pneumatic clamp seat 21, and a bottom plate 25 is arranged between the driving assembly and the pneumatic clamp seat 21. The bottom plate 25 is fixedly arranged on the pneumatic clamp seat 21, and the synchronous belt passes through the bottom plate 25 and is sleeved on the driven wheel 24. A waterproof cover 26 for covering the driving assembly is fixedly arranged above the bottom plate 25, and the servo motor 8 is fixedly arranged on the waterproof cover 26. The output end of the servo motor 8, the driving wheel 23 and the synchronous belt are all located in the waterproof cover 26. In order to ensure that the servo motor 8 is fixed firmly, a support plate for supporting the servo motor 8 is also fixedly arranged on the bottom plate 25, and the support plate is located in the waterproof cover 26. Figure 6 , 7 The middle support plate is not shown.

[0057] 2. Discharging mechanism 3;

[0058] like Figure 3 , 9 As shown, the material discharging mechanism 3 is arranged behind the indexing mechanism 2, and the material discharging mechanism 3 includes a material channel 31 and a material discharging platform 32. A first bracket 33 is arranged between the material discharging platform 32 and the box body 1, and the first bracket 33 is fixedly arranged on the upper surface of the box body 1. The material discharging platform 32 is detachably provided with a first adjustment plate 34 and a second adjustment plate 35. A gap for clamping the steel pipe 10 is formed between the first adjustment plate 34 and the second adjustment plate 35, and the gap size is adapted to the size of the steel pipe 10. Adaptation here means that the width of the gap is equal to or slightly larger than the diameter of the steel pipe 10, so that the steel pipe 10 can be clamped in the gap, but will not be clamped so as to be able to move forward and backward. The width mentioned in this embodiment refers to the distance in the left and right directions.

[0059] The first adjustment plate 34 is detachably connected to the material discharging platform 32 in the following manner: a long hole extending in the left and right directions is provided on the first adjustment plate 34, and an internal threaded hole is provided on the material discharging platform 32. A bolt passes through the long hole and is screwed into the internal threaded hole. The second adjustment plate 35 is detachably connected to the material discharging platform 32 in the same manner as above. If the diameters of the steel pipes 10 to be slotted are different, the bolts can be loosened at this time, and the first adjustment plate 34 and the second adjustment plate 35 can be moved toward or away from each other, so as to adjust the gap size between the first adjustment plate 34 and the second adjustment plate 35 so that they can clamp steel pipes 10 of different sizes.

[0060] like Figure 2 , 9 As shown, a second bracket 36 is provided between the material channel 31 and the box body 1 for supporting the material channel 31. The material channel 31 is inclined and the end close to the material discharge platform 32 is lower. The end of the material channel 31 close to the material discharge platform 32 is the discharge end, which extends to the gap so that the steel pipe 10 can slide down from the material channel 31. Fig.10 , 11 As shown, the longitudinal section of the material channel 31 is U-shaped, and the steel pipe 10 is stuck in the material channel 31. The size of the material channel 31 is matched with the size of the steel pipe 10. The matching here means that the length of the material channel 31 is equal to or slightly larger than the length of the steel pipe 10, so that a number of steel pipes 10 can be placed side by side on the material channel 31 in an orderly manner, and can slide into the gap along the material channel 31. When sliding into the gap, the axial direction of the steel pipe 10 is just along the front and rear directions, so as to avoid the steel pipe 10 being in a disorderly state on the material channel 31 due to the excessive size of the material channel 31, and ultimately failing to slide smoothly into the gap.

[0061] In order to make the material channel 31 adapt to steel pipes 10 of more sizes, in this embodiment, a moving component is provided on the material channel 31, such as Fig.10 , 11 As shown, the moving assembly includes a limit plate 37, which is placed on the material channel 31. An adjusting bolt is arranged between the limit plate 37 and the rear side wall of the material channel 31. A through slot is provided on the limit plate 37, which passes through the top of the limit plate 37. One end of the adjusting bolt is fixed on the rear side wall of the material channel 31, and the other end is fastened with a nut after passing through the through slot of the limit plate 37. If the steel pipe 10 is larger in size, loosen the nut, move the limit plate 37 backward, and then tighten the nut, so that the steel pipe 10 can be placed side by side in an orderly manner between the front side wall of the material channel 31 and the limit plate 37. In this embodiment, multiple adjusting bolts are arranged along the left and right directions; Fig.10 The center adjustment bolt is not shown.

[0062] It should be additionally explained that the dimension between the adjusting bolt and the material channel 31 is larger than the diameter of the steel pipe 10 to prevent the screw from affecting the placement of the steel pipe 10 into the material channel 31 .

[0063] 3. Ejection mechanism 4;

[0064] The ejection mechanism 4 can eject the steel pipe 10 stuck in the gap into the pneumatic clamp 21. Fig.12 , 13 As shown, the ejection mechanism 4 includes a push rod 41 for pushing the steel pipe 10 into the through hole of the pneumatic clamp 21, and a first power element 44 for driving the push rod 41 to perform reciprocating linear motion along the axial direction of the through hole. In this embodiment, the first power element 44 adopts a cylinder with a magnetic switch in the prior art, and the cylinder with a magnetic switch is electrically connected to the electrical control box. The cylinder with a magnetic switch can not only drive the push rod 41 to extend and retract in the forward and backward directions, but also control the push length of the push rod 41 by controlling the cylinder stroke to ensure that the steel pipe 10 is pushed into the pneumatic clamp 21. The fixing method of the cylinder with a magnetic switch is: a connecting plate 42 is fixed on the upper surface of the box body 1, and two cylinder brackets 43 are fixed on the connecting plate 42 at intervals, and the cylinder with a magnetic switch is fixed on the cylinder bracket 43. The diameter of the push rod 41 is matched with the inner diameter of the through hole of the pneumatic clamp seat 21. Matching here means that the diameter of the push rod 41 is equal to or slightly smaller than the inner diameter of the through hole, so that the push rod 41 can extend into the through hole to push the steel pipe 10 forward to a length suitable for grooving.

[0065] In this embodiment, the first power element 44 can also be replaced with any control element in the prior art as long as it can realize the extension and retraction of the push rod 41.

[0066] 4. Cutting mechanism 5;

[0067] The cutting mechanism 5 is used for slotting the steel pipe 10. The cutting mechanism 5 includes a rotary cutting unit for slotting the steel pipe 10, and a feeding unit for driving the rotary cutting unit to perform reciprocating linear motion in a direction close to or away from the steel pipe 10.

[0068] like Fig.14 , 15 As shown, the rotary cutting unit includes a motor 501, a power head 502, a saw blade shaft 503 and a saw blade 504; the motor 501 is electrically connected to the electrical control box, the power head 502 is fixedly arranged at the output end of the motor 501, the saw blade shaft 503 is fixedly arranged at one end of the power head 502 away from the motor 501, and the saw blade 504 is sleeved on the saw blade shaft 503. In this embodiment, a first spacer 505 and a second spacer 506 are fixedly sleeved on the saw blade shaft 503, and the saw blade 504 is located between the first spacer 505 and the second spacer 506. The first spacer 505 and the second spacer 506 not only play a role in clamping the saw blade 504, but also can adjust the position of the saw blade 504. The structures of the first spacer 505 and the second spacer 506 adopt the existing technology and will not be described in detail here.

[0069] like Figure 3 , 16As shown in Figures 1 and 17, the feeding unit includes a motor, a fixed frame 507, a guide rail 508 arranged on the fixed frame 507, and a lead screw 509 rotatably arranged on the fixed frame 507. The motor here adopts the servo motor 8 in the prior art, and the servo motor 8 is electrically connected to the electrical control box. The fixed frame 507 is fixedly mounted on the upper surface of the box body 1, and the servo motor 8 is fixedly mounted on the fixed frame 507. The output end of the servo motor 8 is connected to the lead screw 509, and the lead screw 509 is axially arranged in the front and rear directions. A sliding block adapted to the guide rail 508 and a lead screw nut sleeved on the lead screw 509 are arranged at the bottom of the rotary cutting unit. In this embodiment, a moving plate 510 is fixedly mounted at the bottom of the power head 502, see Fig.14 , a slider and a lead screw nut are provided at one end of the movable plate 510 facing the fixed frame 507. The feeding principle is as follows: the servo motor 8 works to drive the lead screw 509 to rotate, and the movable plate 510 and the rotary cutting unit have a tendency to rotate with the lead screw 509, but the slider cooperates with the guide rail 508 to limit the movable plate 510, so that it cannot rotate. Since the lead screw nut is threadedly connected to the lead screw 509, the movable plate 510 and the rotary cutting unit can only make linear reciprocating motion in the front and rear directions, that is, the feeding direction of the rotary cutting unit is parallel to the extension direction of the steel pipe 10, both along the front and rear directions, to ensure that the rotary cutting unit feeds and cuts the steel pipe 10 into grooves.

[0070] An accordion protective cover is provided between the fixed frame 507 and the rotary cutting unit, which is used for waterproofing, dustproofing, and protecting the guide rail 508 and the lead screw 509. In this embodiment, the accordion protective cover is provided with two sections, wherein the front section is provided between the front end of the fixed frame 507 and the front end of the connecting plate 42, and the rear section is provided between the rear end of the fixed frame 507 and the rear end of the connecting plate 42, and the extension direction of the accordion protective cover is along the axial direction of the lead screw 509. When the rotary cutting unit is fed backward, the front section accordion protective cover is stretched, and the rear section accordion protective cover is contracted. When the rotary cutting unit moves forward, the front section accordion protective cover is contracted, and the rear section accordion protective cover is stretched. The accordion protective cover adopts the existing technology and is not shown in the drawings.

[0071] Since the saw blade 504 generates heat due to friction when cutting the steel pipe 10, in order to cool the saw blade 504 and extend its service life, it is necessary to continuously water it during cutting. However, the saw blade 504 rotates at a high speed during cutting. In order to prevent water from splashing outward, a waterproof baffle 511 is provided at the corresponding working position of the rotary cutting unit, see Fig.14 , 15 , 17, the working position here refers to the position of cutting the steel pipe 10, in other words, the waterproof baffle 511 covers the saw blade shaft 503 and the saw blade 504. Fig.18 As shown, the longitudinal section of the waterproof baffle 511 is an inverted L-shape, covering the saw blade shaft 503 and the upper and front positions of the saw blade 504 , and the splashing water will hit the waterproof baffle 511 .

[0072] 5. Water outlet mechanism;

[0073] Furthermore, the present embodiment is also provided with a water outlet mechanism, which includes a water tank and a water pump arranged inside the box body 1, and also includes a water outlet pipe 7 connected to the water tank, such as Figure 2 , 4 As shown, the water outlet end of the water outlet pipe 7 acts on the working position of the rotary cutting unit (i.e., the position of the saw blade shaft 503 and the saw blade 504). In this embodiment, the water outlet pipe 7 is fixed on the waterproof cover 26 in the indexing mechanism 2. This position is convenient for spraying water on the saw blade 504 when it cuts the steel pipe 10, and it also reasonably utilizes the longitudinal space and reduces the occupation of the lateral space of the device. Figure 2 When working, the water pump pumps out water, and the water flows out through the water outlet end of the water outlet pipe 7, where the water outlet end refers to the end close to the saw blade 504 and the steel pipe 10. During the cutting process of the saw blade 504, the water in the water outlet pipe 7 keeps flowing out to cool the saw blade 504. It should be noted that Figure 3 The middle water outlet pipe 7 is not shown.

[0074] 6. Limiting mechanism 6;

[0075] Although the first power element 44 (i.e., the cylinder with a magnetic switch) in the ejection mechanism 4 can control the stroke of the push rod 41, due to the existence of inertia, when the push rod 41 stops advancing, the steel pipe 10 cannot stop immediately. Therefore, this embodiment also includes a limit mechanism 6 for limiting the extension length of the steel pipe 10 in the pneumatic clamp 21. The limit mechanism 6 is arranged on the upper surface of the box body 1, see Figure 2 , 3 .

[0076] like Fig.19 As shown, the limiting mechanism 6 includes a guide column 62 and a second power element 61 for driving the guide column 62 to extend and retract. The second power element 61 also adopts a cylinder with a magnetic switch in the prior art, and the cylinder with a magnetic switch is electrically connected to the electrical control box. The extension direction of the guide column 62 is perpendicular to the extension direction of the steel pipe 10, that is, along the left and right directions. A floating joint 63 is provided between the cylinder with a magnetic switch and the guide column 62 to compensate for the installation error. The floating joint 63 is a prior art. Here, the cylinder with a magnetic switch can adjust the extension time and extension length of the guide column 62 according to actual application. This part is set as a prior art and will not be described in detail here. In this embodiment, the second power element 61 can also be replaced with any control element in the prior art, as long as the extension and retraction of the guide column 62 can be achieved.

[0077] In this embodiment, a support frame 64 is arranged between the second power element 61 and the upper surface of the box body 1, the support frame 64 is fixed on the box body 1, and the limiting mechanism 6 is fixed on the support frame 64. When the guide column 62 is extended, it is located in front of the steel pipe 10 to prevent the steel pipe 10 from continuing to slide forward due to inertia.

[0078] It should be noted that if Fig.19 As shown, in this embodiment, one end (i.e., the left end) of the guide column 62 used to abut the steel pipe 10 is a pointed structure, which increases the aesthetics. Of course, the guide column 62 as a whole can also be a cylindrical structure.

[0079] 7. Discharging chute 11;

[0080] like Figure 5 As shown, in order to facilitate the collection of the steel pipes 10 after slotting, a discharge chute 11 is further provided on the upper surface of the box body 1. The discharge chute is tilted and fixed on the box body 1. The feed end of the discharge chute 11 is higher than its discharge end. The feed end of the discharge chute 11 is located below the pneumatic clamp seat 21, and is used to receive the steel pipes 10 that fall from the pneumatic clamp seat 21 after slotting. The discharge end of the discharge chute 11 extends from the edge of the box body 1. In this embodiment, an extension chute 9 is connected to the discharge end of the discharge chute 11. The longitudinal sections of the extension chute 9 and the discharge chute 11 are both U-shaped, which can prevent the steel pipe 10 from sliding out from the sides of the extension chute 9 and the discharge chute 11. As shown Figure 2-5 As shown, the slotted steel pipe 10 falls from the pneumatic clamp 21, slides down the discharge chute 11 into the extension chute 9, and finally slides out of the extension chute 9. In actual applications, a collection bag or a collection box is placed on the extension chute 9, and the slotted steel pipe 10 finally slides into the collection bag or the collection box, avoiding the problem that the slotted steel pipe 10 falls directly on the upper surface of the box body 1 and needs to be picked up and collected manually.

[0081] 8. Display screen;

[0082] In order to improve this embodiment, the box body 1 is also provided with a display screen for easy operation, such as Figure 2 As shown, the display screen is electrically connected to the electrical control box, and buttons are set on the display screen to control the start of the motor 501 and the servo motor 8, and adjust the rotation speed of the motor 501 and the servo motor 8 to control the cutting speed and the feeding speed. The installation and operation of the display screen adopt the existing technology and will not be described in detail here. Figure 4 The middle display screen is not shown.

[0083] When using this embodiment, a plurality of steel pipes 10 are manually placed side by side on the material channel 31, and the steel pipe 10 at the bottom slides into the gap between the first adjustment plate 34 and the second adjustment plate 35. The push rod 41 in the material pushing mechanism 4 extends forward under the action of the first power element 44 (i.e., the cylinder with a magnetic switch), and pushes the steel pipe 10 into the pneumatic clamp seat 21. After the push rod 41 reaches the maximum stroke, the steel pipe 10 still has a certain inertia. At this time, the second power element 61 (i.e., the cylinder with a magnetic switch) in the limit mechanism 6 pushes the guide post 62 to the front of the steel pipe 10. After the steel pipe 10 hits the guide post 62, it no longer slides forward and stays at this position. The cylinder in the pneumatic clamp seat 21 works to make the clamp clamp the steel pipe 10, and the guide post 62 retreats after the steel pipe 10 is clamped. The motor 501 in the cutting mechanism 5 is started, driving the saw blade 504 to rotate for cutting and grooving. At the same time, the servo motor 8 in the cutting mechanism 5 drives the lead screw 509 to rotate, so that the rotary cutting unit is fed backward to complete the grooving work of the specified length.

[0084] When the slotting is completed at this position, the servo motor 8 in the indexing mechanism 2 is started, driving the driving wheel 23 to rotate, thereby causing the synchronous belt to drive the clamp and the rotating shaft in the pneumatic clamp seat 21 to rotate, and the steel pipe 10 to rotate. After the slotting position is changed, the cutting mechanism 5 is continued to cut the steel pipe 10, and finally 4 or more slots along the axial direction are opened on the steel pipe 10. This embodiment can automatically change the slotting position of the steel pipe 10 during the slotting process, and multiple mechanisms such as the indexing mechanism 2, the material discharge mechanism 3, the material ejection mechanism 4, and the cutting mechanism 5 are assembled on the box body 1, which reasonably utilizes the longitudinal space, reduces the floor space, and improves the working efficiency.

[0085] It should be noted that the above is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiment, those skilled in the art can still modify the technical solutions recorded in the above embodiment or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
