Description

Technical Field

[0001] The utility model relates to the technical field of pipe cutting and processing, in particular to automatic coil cutting equipment. Background Art

[0002] In the process of coil processing, the so-called cutting is to cut the coil with a certain length according to the actual needs of the product by manual or mechanical means according to the required specification length, so that the copper tubes after cutting are of the same size, which is convenient for subsequent processing operations.

[0003] For example, Chinese patent CN116213510A discloses a single-tube straightening and chipless cutting machine, which specifically discloses that a feeding device and a cutting device can be set on the machine, the feeding device is used to transport the copper tube, and then the cutting device is used to fix the copper tube, and the cutting head of the cutting device is used to cut the copper tube to meet the needs of cutting copper tubes of different lengths and specifications. However, after the copper tube is cut, under the action of residual stress, a certain deformation will occur at its incision, which is specifically manifested as a certain degree of contraction (i.e. shrinkage) of the tube mouth of the copper tube; therefore, generally speaking, the copper tube will be expanded after cutting to facilitate the subsequent connection between the copper tubes. However, at present, the process of expanding the copper tube is either done manually after cutting, which will lead to low overall work efficiency, and if the worker does not control the strength well, the expansion of the tube mouth may be too large or too small, which may require rework; or the process is done by expanding the tube alone using a expanding machine; this results in a cumbersome process, that is, two sets of equipment are needed to complete the cutting and expanding of the copper tube respectively, which also leads to reduced production efficiency.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art. The terms used in the specification herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0041] refer to Figure 1-10 The utility model provides a coil automatic cutting device, comprising a frame 1, and a feeding device 2, a cutting device 3 and a flaring device 4 which are sequentially arranged on the frame 1;

[0045] The specific working process of the pipe cutting equipment provided by the utility model is as follows:

[0046] First, the pipe is sent to the working area of ​​the cutting device 3 by the feeding device 2 for cutting; specifically, the clamping die assembly 22 first clamps the pipe to be cut, and at this time, the first driving member 20 (such as a cylinder) drives the conveying seat 21 to move toward the cutting device 3. As the conveying seat 21 moves, the pipe enters the other end (that is, the pipe groove 3010) from one end. Fig.10 The pipe groove 3010 moves from the right end to the left end), and the conveying seat 21 stops moving when the desired cutting length is reached; the second driving member 310 drives the cutting knife 311 to move in the direction of the pipe groove 3010 until the cutting knife 311 contacts the surface of the pipe fitting, and then cuts the pipe fitting. Since the pipe fitting after cutting will form a shrinkage at its cut end (that is, the pipe fitting will be deformed under the action of residual stress as mentioned in the background technology), the third driving member drives the punch 41 to move in the direction of the cutting device 3, so that the punch 41 can punch into the pipe fitting, thereby expanding the pipe fitting.

That is, the pipe enters the cutting device 3 from one end of the pipe groove 3010, and then continuously exits from the through hole 3120 of the rotating disk 312; after reaching the required length, the cutting blade 311 moves toward the through hole 3120 until it contacts the surface of the pipe, and then starts cutting.

[0050] refer to Figure 3 and 4 In a preferred embodiment, the cutting assembly 31 further includes a sleeve 316 and a fourth driving member 315.

Figure 4In this embodiment, the sleeve 316 is connected to the support tube 301 through a bearing, so that when the fourth driving member 315 (which can be a motor) drives the sleeve 316 to rotate, the support tube 301 will not rotate. Further, the output end of the fourth driving member 315 is connected with a rotating wheel, and the rotating wheel and the sleeve 316 are connected by a belt transmission; therefore, when the fourth driving member 315 is working, it can drive the sleeve 316 to rotate; and one end of the sleeve 316 is also connected to a rotating disk 312; and the cutting knife 311 is connected to the rotating disk 312, so when the sleeve 316 rotates, it will also drive the rotating disk 312 and the cutting knife 311 to rotate together; therefore, when the second driving member 310 drives the cutting knife 311 to move to contact the surface of the pipe fitting, the fourth driving member 315 drives the cutting knife 311 to rotate, so that the cutting work of the pipe fitting is completed during the rotation process.

[0051] refer to Figure 3 and 4 In a preferred embodiment, the cutting assembly 31 also includes a driving sleeve 313 and a slider 314. The driving sleeve 313 is sleeved outside the sleeve 316. One end of the driving sleeve 313 is connected to the second driving member 310, and the other end is connected to the slider 314. The second driving member 310 can drive the slider 314 to move left and right through the driving sleeve 313; the end surface of the sleeve 316 close to the rotating disk 312 is provided with an inclined surface 3160 that cooperates with the oblique wedge of the slider 314; the slider 314 is also connected to the cutting knife 311; the rotating disk 312 is also provided with a slide groove 3121, and the slide groove 3121 is spaced apart from the through hole 3120; when the slider 314 moves left and right, it can drive the cutting knife 311 to move in the slide groove 3121 toward the direction of the through hole 3120.

Figure 4 Specifically, the output end of the second driving member 310 is connected to a driving block, the driving block is connected to the driving sleeve 313, and there is a space between the driving sleeve 313 and the sleeve 316 for the driving sleeve 313 to reciprocate left and right (i.e. Figure 4 Therefore, under the cooperation of the slider 314 and the inclined wedge of the inclined surface 3160, when the driving sleeve 313 moves left and right, the cutting knife 311 can be driven by the slider 314 to move toward the through hole 3120 or away from the through hole 3120.

[0053] In this embodiment, there are two sliders 314, which are respectively disposed at the upper and lower ends of the driving sleeve 313 (i.e. Figure 4Similarly, two slide slots 3121 are also provided on the rotating disk 312. The cutting assembly 31 further includes a positioning wheel 317. One end of the two sliders 314 is connected to the driving sleeve 313, and the other ends of the two sliders 314 are connected to the cutting knife 311 and the positioning wheel 317 respectively; specifically, Figure 4 As can be seen from the figure, the inclined surface 3160 of the sleeve 316 is inclined toward the direction of the through hole 3120. When the driving sleeve 313 moves to the left, it will bring the slider 314 to move along the slope of the inclined surface 3160. One of the sliders 314 (i.e. Figure 4 The slider 314 connected to the upper end of the driving sleeve 313 moves downward along the slope of the inclined surface 3160, and the other slider 314 (i.e. Figure 4 The slider 314 connected to the lower end of the driving sleeve 313 moves upward along the slope of the inclined surface 3160, thereby driving the cutting knife 311 and the positioning wheel 317 to move toward the through hole 3120 respectively until they contact the surface of the pipe and then perform the cutting work. When the pipe cutting is completed, the driving sleeve 313 moves to the right, and the movement direction of the two sliders 314 changes, thereby driving the cutting knife 311 and the positioning wheel 317 to move away from the through hole 3120. In this embodiment, "moving to the left, moving to the right, up and down" are only for illustration and do not represent a limitation.

[0054] refer to Figure 1 , 5 , 10, in a preferred embodiment, the frame 1 is further provided with a clamping device 5 and a breaking device 6, the clamping device 5 is located between the cutting device 3 and the feeding device 2, and the breaking device 6 is located between the cutting device 3 and the expanding device 4; Figure 6 The clamping device 5 and the breaking device 6 both include a fixed seat 50, and a cylinder 51 and a clamp 52 arranged on the fixed seat 50, the clamp 52 includes two first clamping blocks 520 arranged opposite to each other; the two first clamping blocks 520 are each provided with a groove, and the groove is arranged along the length direction of the first clamping block 520; the cylinder 51 can drive the two clamping blocks to connect or separate with each other; when the cylinder 51 drives the two first clamping blocks 520 to connect with each other, the grooves are connected to form a receiving groove 521, and the clamp 52 can clamp the pipe fitting in the receiving groove 521; when the cylinder 51 drives the two first clamping blocks 520 to separate, the clamp 52 can loosen the pipe fitting; the receiving groove 521 and the pipe groove 3010 are at the same horizontal height.

[0055] In this embodiment, the clamping device 5 can further fix the pipe during the pipe cutting process; and since the cutting knife 311 does not completely cut the pipe after cutting, when the cutting knife 311 cuts the pipe to a certain depth, the breaking device 6 will finally break the pipe, so as to achieve the purpose of chip-free cutting. When the clamping die assembly 22 of the feeding device 2 transports the pipe toward the cutting device 3, the two first clamping blocks 520 of the clamping device 5 and the breaking device 6 are in a state of separation from each other, so that the pipe can pass through the receiving groove 521 smoothly; and when preparing to cut, the cylinder 51 drives the two first clamping blocks 520 to connect with each other, so as to clamp the pipe and prevent the pipe from shaking during the cutting process.

[0056] refer to Figure 1 , 5 10. In a preferred embodiment, the breaking device 6 further comprises a first guide rod 60 and a fifth driving member 61.

The fifth driving member 61 can drive the fixing seat 50 of the breaking device 6 to move on the first guide rod 60 toward the direction of the cutting knife 311. Specifically, when the cutting knife 311 cuts the pipe to a certain depth, since the pipe is not completely cut off at this time, the fixing seat 50 is driven to move by the second driving member 310 (i.e. Figure 5 The pipe is completely broken by the left movement in the middle of the cutting tool, thereby achieving chip-free cutting.

[0057] refer to Figure 1 , 7 -8, 10, in the preferred embodiment, the flaring device 4 also includes a sliding seat 42; the third driving member and the die 41 are both arranged on the sliding seat 42, and the third driving member includes a first driving source 40 and a second driving source arranged at intervals, the first driving source 40 can drive the die head to rotate; the second driving source (not shown) can drive the die head to move in the direction of the tube groove 3010; the frame 1 is also provided with a third driving source 43 and a slide rail 44, and the slide rail 44 is arranged along the width direction of the frame 1; the sliding seat 42 is slidably connected to the slide rail 44; the sliding seat 42 is also provided with a blanking plate 45, and the blanking plate 45 is arranged at intervals on one side of the die 41; the third driving source 43 can drive the die 41 and the blanking plate 45 to move forward and backward on the frame 1 through the sliding seat 42; the blanking plate 45 is inclined from one end to the other end (specifically inclined toward the outside of the frame 1). The so-called forward and backward movement refers to movement in the direction of the central axis of the accommodating groove 521.

[0058] During the feeding process of the pipe fittings, the expansion device 4 is always in the initial position (i.e. Fig.10The state shown in the figure is to prevent the expansion device 4 from interfering with the normal feeding of the pipe fitting; after the pipe fitting is cut, the feeding device 2 continues to push the pipe fitting forward for a distance until the cut of the pipe fitting extends out of the receiving groove 521 of the breaking device 6. At this time, the clamp 52 maintains the clamping state of the pipe fitting, and then the third driving source 43 drives the punch 41 to move to the working position. At this time, the punch 41 is just on the same axis as the receiving groove 521 of the breaking device 6, and then the second driving source drives the punch 41 to move in the direction of the pipe groove 3010 until the punch 41 punches into the pipe mouth of the pipe fitting; then the first driving source 40 drives the punch 41 to rotate, thereby achieving the effect of expanding the shrinkage of the pipe fitting. After the expansion work is completed, the third driving source 43 drives the punch 41 back to the initial position again; and so on. The drop tray 45 is mainly used to receive the cut pipes, and the tilted arrangement of the drop tray 45 is conducive to the cut pipes to drop directly into the collection box (not shown) below through the drop tray 45.

The motor 201 can drive the conveying seat 21 to reciprocate on the second guide rod 203 through the screw rod 202; the clamping mold assembly 22 includes a fourth driving source 221 and two oppositely arranged second clamping blocks 222, the fourth driving source 221 is connected to one of the second clamping blocks 222, and the fourth driving source 221 can drive one of the second clamping blocks 222 to approach or move away from the other second clamping block 222; when the two second clamping blocks 222 are connected, a pipe hole 223 for the pipe fitting to pass through is formed; the pipe hole 223 and the pipe groove 3010 are at the same horizontal height.

[0060] In this embodiment, the motor 201 drives the screw rod 202 to make axial movement, thereby driving the conveying seat 21 to move in the direction of the cutting device 3; when the pipe starts to feed, the fourth driving source 221 can drive one of the second clamping blocks 222 to move against the other second clamping block 222, so that the pipe can move in the pipe hole 223; when the pipe needs to be conveyed, the fourth driving source 221 drives one of the second clamping blocks 222 to connect with the other second clamping block 222, so as to clamp the pipe. After clamping, the motor 201 drives the conveying seat 21 to move through the screw rod 202, so as to move the pipe in the direction of the cutting device 3; it should be noted that when the two second clamping blocks 222 clamp the pipe, the two first clamping blocks 520 of the clamping device 5 and the breaking device 6 are in a separated state so that the pipe can be conveyed normally.
