Description

TECHNICAL FIELD

[0001] The present application relates to the field of pipe cutting, in particular to a spring pipe cutting device. BACKGROUND

[0002] A spring pipe (such as a spring air pipe, a spring water pipe, etc.) is formed by winding an elongated plastic pipe or rubber pipe, and its structure is similar to a spring. The spring pipe can be self-adaptively elongated when being pulled, and its delivery stroke for fluid is much greater than its length along the axial direction, and these advantages make the spring pipe be widely used in the field of fluid delivery.

[0003] In actual use, it is often necessary to cut the spring pipe into a spring segment of a predetermined length according to actual needs, and then install the spring segment into a fluid delivery device. There is no special spring pipe cutting device to cut the spring pipe in the prior art, so the cutting of the spring pipe is generally implemented manually. The manual cutting method is low in efficiency and difficult to meet the production needs. CONTENT OF THE INVENTION

[0004] In view of the above technical problems, the present application provides a spring pipe cutting device, and the detailed technical scheme is as follows:

[0005] A spring pipe cutting device includes a mounting seat, a mounting shaft, a first pressing mechanism, a second pressing mechanism, and a cutting mechanism, wherein:

[0006] The first end of the mounting shaft is fixedly connected to the mounting seat, and the mounting shaft is arranged in a horizontal direction. The spring pipe to be cut is sleeved onto the mounting shaft through the second end of the mounting shaft;

[0007] The first pressing mechanism is arranged close to the first end of the mounting shaft and is configured to be movable towards the second pressing mechanism to press the spring pipe from the first end to the second pressing mechanism;

[0008] The second pressing mechanism is arranged close to the second end of the mounting shaft and is configured to be movable towards the first pressing mechanism to abut against the second end of the mounting shaft to press the spring pipe from the second end to the first pressing mechanism;

[0009] The cutting mechanism is configured to cut off the spring pipe pressed by the first pressing mechanism and the second pressing mechanism to obtain a spring pipe segment of a predetermined length close to the second end of the mounting shaft;

[0010] The second pressing mechanism is further configured to move away from the first pressing mechanism to release the spring pipe segment on the mounting shaft, and the first pressing mechanism is further configured to continue to move towards the second pressing mechanism to push the spring pipe segment out of the second end of the mounting shaft.

[0011] After the spring tube to be cut is mounted on the mounting shaft, the first pressing mechanism and the second pressing mechanism press against the two ends of the spring tube to fix the spring tube, so as to ensure that the cutting mechanism can cut off the spring tube to obtain a spring tube segment with a predetermined length near the second end of the mounting shaft. Subsequently, the second pressing mechanism releases the spring tube segment, and the second pressing mechanism pushes the spring tube segment out of the second end of the mounting shaft to implement automatic unloading of the current obtained spring tube segment. The above cutting process is repeated until the spring tube on the mounting shaft is cut into a predetermined number of spring tube segments.

[0022] The second pressing assembly is provided, so that the second pressing assembly can elastically press the second end of the spring tube, preventing the spring tube from being pressed too much and causing the pipeline to be cut and the adjacent pipelines on both sides to be clamped, and finally causing the cutting mechanism to fail to cut the pipeline at the cutting position.

Detailed Implementation

[0062] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, this application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0063] like Figures 1 to 3 As shown, the spring cutting device in this embodiment includes a mounting base 1, a mounting shaft 2, a first pressing mechanism 3, a second pressing mechanism 4, and a cutting mechanism 5, wherein:

[0064] The first end (e.g., the right end) of the mounting shaft 2 is fixedly connected to the mounting base 1. The mounting shaft 2 is set in a horizontal direction. The spring tube 100 to be cut is fitted onto the mounting shaft 2 via the second end (e.g., the left end).

[0065] The first pressing mechanism 3 is disposed near the first end of the mounting shaft 2 and is configured to move toward the second pressing mechanism 4 to press the spring tube 100 from the first end of the spring tube 100 toward the second pressing mechanism 4.

[0066] The second pressing mechanism 4 is disposed near the second end of the mounting shaft 2 and is configured to move toward the first pressing mechanism 3 and abut against the second end of the mounting shaft 2 to press the spring tube 100 from the second end of the spring tube 100 toward the first pressing mechanism 3.

[0067] The cutting mechanism 5 is configured to cut off the spring tube 100 pressed by the first pressing mechanism 3 and the second pressing mechanism 4 to obtain a spring tube segment with a predetermined length close to the second end of the mounting shaft 2.

[0068] The second pressing mechanism 4 is further configured to move away from the first pressing mechanism 3 to release the spring tube segment on the mounting shaft 2. The first pressing mechanism 4 is further configured to continue to move towards the second pressing mechanism 4 to push the spring tube segment out of the second end of the mounting shaft 2.

[0069] The optional working process of the spring cutting device in the embodiment of the present application is as follows:

[0070] The spring tube 100 to be cut is sleeved on the mounting shaft 2 through the second end of the mounting shaft 2.

[0071] The first pressing mechanism 3 and the second pressing mechanism 4 are controlled to move relatively close to each other, so that the first pressing mechanism 3 and the second pressing mechanism 4 cooperate to press the two ends of the spring tube 100 to fix the spring tube 100.

[0072] Then, the cutting mechanism 5 cuts off the spring tube 100 pressed by the first pressing mechanism 3 and the second pressing mechanism 4 to obtain a spring tube segment with a predetermined length close to the second end of the mounting shaft 2.

[0073] Then, the second pressing mechanism 4 moves away from the first pressing mechanism 3 to release the spring tube segment, and the second pressing mechanism 4 pushes the spring tube segment out of the second end of the mounting shaft 2 to implement automatic unloading of the currently obtained spring tube segment.

[0074] The first pressing mechanism 3 and the second pressing mechanism 4 are controlled to move relatively close to each other again, and the above cutting operation is repeated until the spring tube 100 is cut into a predetermined number of spring tube segments.

[0075] It can be seen that the spring tube cutting device provided by the present application realizes automatic cutting of the spring tube, thereby improving the cutting efficiency of the spring tube.

[0076] As shown in Figure 2 Optionally, the first pressing mechanism 3 includes a first translation driving assembly 31 and a first pressing assembly 32, wherein the first pressing assembly 32 is slidingly sleeved on the mounting shaft 2 and is in transmission connection with the first translation driving assembly 31, and the first translation driving assembly 31 drives the first pressing assembly 32 to slide along the mounting shaft 2.

[0077] When it is needed to control the cutting mechanism 5 to implement cutting of the spring tube 100, the first translation driving assembly 31 is configured to drive the first pressing assembly 32 to slide along the mounting shaft 2 towards the second pressing mechanism 4, so that the first pressing assembly 32 presses the first end of the spring tube 100.

[0078] When it is required to automatically unload the spring tube segment from the mounting shaft 2, the first translation driving assembly 31 is configured to drive the first pressing assembly 32 to continuously move along the mounting shaft 2 towards the second pressing mechanism 4, so as to push the spring tube segment out of the second end of the mounting shaft 2.

[0079] As the spring tube 100 is continuously cut, the spring tube 100 on the mounting shaft 2 is continuously shortened. By sleeving the first pressing assembly 32 on the mounting shaft 2, it can be ensured that when the first translation driving assembly 31 drives the first pressing assembly 32 to slide towards the second pressing mechanism 4, the first pressing assembly 32 can press against the first end of the spring tube 100 and push the spring tube segment out of the second end of the mounting shaft 2.

[0080] As shown in Figure 2 Optionally, the first translation driving assembly 31 comprises a first translation driving member 311 and a first moving frame 312, wherein the first moving frame 312 is connected to the driving end of the first translation driving member 311, the first pressing assembly 32 is arranged on the first moving frame 312, and the first translation driving member 31 drives the first moving frame 312 to translate towards or away from the second pressing mechanism 4, so as to drive the first pressing assembly 32 to slide along the mounting shaft 2. The first translation driving member 311 may, for example, be an electric cylinder, a motor cooperating with a screw nut mechanism, or the like.

[0081] Optionally, the first pressing assembly 32 comprises a first mounting plate 321, a first pressing plate 322, and a plurality of (for example, four) first elastic connecting members 323, wherein: the first mounting plate 321 is connected to the movable part of the first translation driving assembly 31, for example, to the first moving frame 312 in the foregoing embodiment. The first pressing plate 322 is connected to the first mounting plate 321 through the plurality of first elastic connecting members 323, and the first pressing plate 322 and the first mounting plate 321 are both provided with first avoiding holes, and the first end of the mounting shaft 2 passes through the first avoiding holes on the first pressing plate 322 and the first mounting plate 321 and is then connected to the mounting seat 1.

[0082] When the first translation driving assembly 31 drives the first mounting plate 321 to translate towards the second pressing mechanism 4, the first pressing plate 322 elastically presses against the first end of the spring tube 100, and the plurality of first elastic connecting members 323 are compressed under pressure.

[0083] Through the above arrangement of the first pressing assembly 32, the first pressing assembly 32 can elastically press against the first end of the spring tube 100, so that the spring tube 100 can be prevented from being pressed too hard, causing the pipeline to be cut in the spring tube 100 and the adjacent pipelines on both sides to be pressed together, resulting in the adjacent pipelines being mistakenly cut when the cutting mechanism 5 cuts the pipeline to be cut.

[0084] As shown in Figure 2As shown, the first elastic connecting member 323 comprises a first connecting bolt and a first spring. The first end of the first connecting bolt is fixedly connected to the first mounting plate 321, and the second end of the first connecting bolt is slidably connected to the first pressing plate 322. The first spring is sleeved on the first connecting bolt, and the two ends of the first spring are respectively abutted against the first mounting plate 321 and the first pressing plate 322.

[0085] When the first translation driving assembly 31 drives the first mounting plate 321 to translate towards the second pressing mechanism 4, the first pressing plate 322 is pressed to abut against the first end of the spring tube 100, and the first pressing plate 322 is retracted along the first connecting bolt towards the first mounting plate 321, and the first spring is compressed, so that the first pressing plate 322 is elastically pressed to abut against the first end of the spring tube 100.

[0086] In order to prevent the first connecting bolt from being stuck when sliding relative to the first pressing plate 322, the first connecting bolt is slidably connected to the first pressing plate 322 through a first linear bearing 324.

[0087] Optionally, the first pressing assembly 32 further comprises a sensing sheet 325 arranged on the first pressing plate 322 and a sensor arranged on the first mounting plate 321. When the first pressing plate 322 is retracted towards the first mounting plate 321 to a predetermined distance, the sensor senses the sensing sheet 325. At this time, the first translation driving assembly 31 stops driving the first mounting plate 321 to translate towards the second pressing mechanism 4, or drives the first mounting plate 321 to move away from the second pressing mechanism 4 by a predetermined distance, or drives the first mounting plate 321 to move away from the second pressing mechanism 4 until the sensing sheet 325 is away from the sensor so that the sensor loses the sensing signal. In this way, the first pressing plate 322 can be pressed to abut against the first end of the spring tube 100 with a predetermined pressure, so that the contraction degree of the spring tube 100 can meet the cutting requirement of the cutting mechanism 5 on the pipeline to be cut. The sensor can be an optical sensor.

[0088] In another embodiment, the first end of the first connecting bolt is fixedly connected to the first pressing plate 322, the second end of the first connecting bolt is slidably connected to the first mounting plate 321, the first spring is sleeved on the first connecting bolt, and the two ends of the first spring are respectively abutted against the first mounting plate 321 and the first pressing plate 322. In this way, when the first translation driving assembly 31 drives the first mounting plate 321 to translate towards the second pressing mechanism 4, the first pressing plate 322 can also elastically abut against the first end of the spring tube 100.

[0089] As shown, Figures 3 to 4As shown, optionally, the second pressing mechanism 4 comprises a second translational driving assembly 41 and a second pressing assembly 42, wherein: the second pressing assembly 42 is connected to the movable part of the second translational driving assembly 41 and is located outside the second end of the mounting shaft 2.

[0090] When it is required to control the cutting mechanism 5 to perform cutting on the spring tube 100, the second translational driving assembly 41 is configured to drive the second pressing assembly 42 to move towards the first pressing mechanism 3, so that the second pressing assembly 42 presses against the second end of the spring tube.

[0091] When it is required to automatically unload the spring tube segment from the mounting shaft 2, the second translational driving assembly 41 is configured to drive the second pressing assembly 42 to move away from the first pressing mechanism 3, so that the second pressing assembly 42 releases the cut spring tube segment.

[0092] The second translational driving assembly 41 comprises a second translational driving member 411 and a second moving frame 412, wherein: the second moving frame 412 is connected to the driving end of the second translational driving assembly 41, the second pressing assembly 42 is arranged on the second moving frame 412, and the second translational driving member 411 drives the second moving frame 412 to translate towards or away from the first pressing mechanism 3, thereby driving the second pressing assembly 42 to translate synchronously. The second translational driving member 411 may, for example, be a pneumatic cylinder, an electric cylinder, a motor cooperating with a screw nut mechanism, or the like translational driving member.

[0093] Optionally, the second pressing assembly 42 comprises a second mounting plate 421, a second pressing plate 422, and a plurality of (for example, four) second elastic connecting members 423, wherein: the second mounting plate 421 is connected to the movable part of the second translational driving assembly 41, for example, to the second moving frame 412 in the foregoing embodiment. The second pressing plate 422 is connected to the second mounting plate 421 via the plurality of second elastic connecting members 423, and the second pressing plate 422 is provided with a second avoiding hole 424.

[0094] When the second translational driving assembly 41 drives the second mounting plate 421 to translate towards the first pressing mechanism 3, the second end of the mounting shaft 2 abuts against the second mounting plate 421 after passing through the second avoiding hole 424, the second pressing plate 422 elastically presses against the second end of the spring tube 100, and the plurality of second elastic connecting members 423 are compressed under pressure.

[0095] By arranging the second pressing assembly 42, the second pressing assembly 42 can elastically press against the second end of the spring tube 100, preventing the spring tube 100 from being pressed too hard, causing the target tube line at the cutting position of the spring tube 100 and the adjacent tube lines on both sides to be pressed together, resulting in the cutting mechanism 5 cutting the target tube line at the cutting position and causing the adjacent tube lines to be cut by mistake.

[0096] As shown in the foregoing embodiments, the first pressing mechanism 3 and the second pressing mechanism 4 are arranged on the same side of the mounting shaft 2, and the second pressing mechanism 4 is arranged outside the second end of the mounting shaft 2. Figure 4As shown, optionally, the second elastic connecting piece 423 comprises a second connecting bolt 428 and a second spring 427, wherein the first end of the second connecting bolt 428 is fixedly connected to the second mounting plate 421, the second end of the second connecting bolt 428 is slidably connected to the second pressing plate 422, the second spring 427 is sleeved on the second connecting bolt 428, and the two ends of the second spring 427 are respectively abutted against the second mounting plate 421 and the second pressing plate 422.

[0097] When the second translation driving assembly 41 drives the second mounting plate 421 to translate towards the first pressing mechanism 3, driving the second pressing plate 422 to press against the second end of the spring tube 100, the second pressing plate 422 slides towards the second mounting plate 421 after being pressed, and the second spring 427 is compressed after being pressed, so that the second pressing plate 422 is elastically pressed against the second end of the spring tube 100.

[0098] In order to prevent the second connecting bolt 428 from being jammed when sliding relative to the second pressing plate 422, optionally, the second connecting bolt 428 is slidably connected to the second pressing plate 422 through the second linear bearing 426.

[0099] In another embodiment, the first end of the second connecting bolt 428 is fixedly connected to the second pressing plate 422, the second end of the second connecting bolt 428 is slidably connected to the second mounting plate 421, the second spring 427 is sleeved on the second connecting bolt 428, and the two ends of the second spring 427 are respectively abutted against the second mounting plate 421 and the second pressing plate 422. In this way, when the second translation driving assembly 41 drives the second mounting plate 421 to translate towards the first pressing mechanism 3, the second pressing plate 422 can also elastically press against the second end of the spring tube 100.

[0100] As shown, Figure 4 Optionally, the second mounting plate 421 is provided with a positioning pin 425 at a position corresponding to the second avoiding hole 424, the second end of the mounting shaft 2 has a positioning hole, or the mounting shaft 2 is a hollow shaft. When the second translation driving assembly 41 drives the second mounting plate 421 to translate towards the spring tube, the positioning pin 425 is inserted into the port of the positioning hole of the mounting shaft 2 or the hollow port.

[0101] In this way, when the first pressing mechanism 3 and the second pressing mechanism 4 press against the spring tube from both ends, the positioning pin 425 can position the second end of the mounting shaft 2, avoiding the second end of the mounting shaft 2 from shaking during the cutting process, thereby improving the cutting precision of the cutting mechanism 5 on the spring tube 100.

[0102] As shown in Figure 5, optionally, the cutting mechanism 5 includes a third translation drive assembly 51, a lifting drive assembly 52, a lifting frame 53, and a cutting assembly 54, wherein: the lifting drive assembly 52 is connected to the movable part of the third translation drive assembly 51, the lifting frame 53 is connected to the movable part of the lifting drive assembly 52, and the cutting assembly 54 is disposed on the lifting frame 53. The third translation drive assembly 51 is configured to drive the cutting assembly 54 to move above the spring tube 100, the lifting drive assembly 52 is configured to drive the cutting assembly 54 to descend toward the spring tube 100, and the cutting assembly 54 is configured to cut the spring tube 100 to obtain a spring tube segment.

[0103] As can be seen, through the coordinated drive of the third translation drive assembly 51 and the lifting drive assembly 52, the cutting assembly 54 can accurately move above the pipeline to be cut on the spring tube 100 and then descend towards the spring tube 100 to cut the spring tube 100. After cutting the spring tube 100, the cutting assembly 54 rises and avoids the spring tube 100, so that the second pressing mechanism 4 can push the spring tube segment out of the mounting shaft 2.

[0104] like Figure 5 As shown, optionally, the third translation drive assembly 51 includes a fixed plate 511, a third translation drive component 512, and a third movable frame 513. The third movable frame 513 is slidably connected to the fixed plate 511 via a slide rail pair and is drively connected to the third translation drive component 512 mounted on the fixed plate 511. The lifting drive assembly 52 is mounted on the third movable frame 513. The third translation drive component 512 drives the third movable frame 513 to translate relative to the fixed plate 511, thereby causing the lifting drive assembly 52, the lifting frame 53, and the cutting assembly 54 to translate.

[0105] The third translation drive component 512 can be, for example, a cylinder, an electric cylinder, a motor, or a lead screw and nut mechanism.

[0106] like Figures 5 to 7 As shown, optionally, the cutting assembly 54 includes a mounting block 541, a first push block 542, a second push block 543, a lifting drive 544, a blade holder 545, and a blade 546, wherein: the mounting block 541 is disposed on the lifting frame 53. The first push block 542 and the second push block 543 are both rotatably mounted on the mounting block 541, and a cutting channel is formed between the first push block 542 and the second push block 543.

[0107] The lifting drive component 544 is mounted on the lifting frame 53 and located above the mounting block 541. The blade holder 545 passes through the cutting channel. The upper end of the blade holder 545 is connected to the drive end of the lifting drive component 544, and the blade 546 is connected to the lower end of the blade holder 545.

[0108] When the cutting assembly 54 is driven to descend by the lifting driving assembly 52, the lower ends of the first push block 542 and the second push block 543 are inserted into the adjacent two tube gaps on the spring tube, and as the lower ends of the first push block 542 and the second push block 543 are continuously squeezed into the adjacent two tube gaps, the tube lines push back the first push block 542 and the second push block 543 under pressure, thereby driving the first push block 542 and the second push block 543 to rotate, and the lower ends of the first push block 542 and the second push block 543 are away from each other, thereby supporting the spring tube 100. The lifting driving member 544 is configured to drive the knife holder 545 to descend, and the blade 546 cuts the spring tube 100 between the first push block 542 and the second push block 543.

[0109] In order to enable the first push block 542 and the second push block 543 to be smoothly squeezed into the corresponding tube gap, as shown in Figure 6 Optionally, the outer side of the lower end of the first push block 542 and the second push block 543 is provided as an inwardly inclined inclined surface, and the lower end of the first push block 542 and the second push block 543 is pointed.

[0110] In combination with Figure 6 As shown in the optional cutting process of the cutting assembly 54 on the spring tube 100 is as follows:

[0111] Firstly, the blade 546 of the cutting assembly 54 is moved to the tube line 101 to be cut of the spring tube 100 by the translational driving of the third translational driving assembly 51.

[0112] Then, the cutting assembly 54 is driven to descend by the lifting driving assembly 52, so that the lower ends of the first push block 542 and the second push block 543 are inserted into the two tube gaps on both sides of the tube line 101 to be cut, and at the same time, the lower ends of the first push block 542 and the second push block 543 are away from each other under pressure, thereby pushing the two adjacent tube lines 102 on both sides of the tube line 101 to be cut away from the tube line 101 to be cut, so that the space is generated between the tube line 101 to be cut and the two adjacent tube lines 102, so as to prevent the blade 546 from cutting the two adjacent tube lines 102.

[0113] Finally, the knife holder 545 is driven to descend by the lifting driving member 544, and the blade 546 cuts the tube line 101 to be cut between the first push block 542 and the second push block 543.

[0114] It can be seen that by setting the cutting assembly 54, the blade 546 can implement precise cutting of the tube line 101 to be cut of the spring tube 100, and avoid cutting the adjacent tube lines 102.

[0115] Optionally, the second push block 543 is installed in the same way as the first push block 542. As shown in Figures 8 to 9As shown, taking the first push block 542 as an example, at least two mounting holes 547 are arranged on the first push block 542 in a vertical direction, the first push block 542 is screwed to the mounting block 541 through a third bolt 548 penetrating the mounting hole 547, the diameter of the mounting hole 547 is greater than the diameter of the screw rod of the third bolt 548, and the first push block 542 is configured to rotate around the third bolt 548 in the highest mounting hole 547. In order to prevent the first push block 542 from moving along the axis of the third bolt 548 in the highest mounting hole 547, a spring can be sleeved on the third bolt 548 in the highest mounting hole 547.

[0116] When the lifting driving member 544 drives the tool holder 545 to descend and the first push block 542 and the second push block 543 are inserted into the pipe gap on both sides of the pipeline 101, the first push block 542 and the second push block 543 are synchronously rotated outward around the third bolt 548 in the corresponding mounting hole 547 under pressure, so as to push the two adjacent pipelines 102 on both sides of the pipeline 101 away from the pipeline 101 to be cut off.

[0117] As shown in the figure, Figures 7 to 9 Optionally, the first push block 542 and the second push block 543 are respectively provided with first guide grooves 5411 and second guide grooves 5412 extending in a vertical direction on the side walls of the tool holder 545. The first guide grooves 5411 and the second guide grooves 5412 are respectively matched with first guide strips 549 and second guide strips 5410 arranged on the two side walls of the tool holder 545. When the lifting driving member 544 drives the tool holder 545 to descend, the first guide strips 549 slide downward along the first guide grooves 5411, and the second guide strips 5410 slide downward along the second guide grooves 5412, so as to guide the tool holder 545 and the blade 546, prevent the blade 546 from deviating during the descending process, and improve the cutting effect of the blade 546 on the spring pipe 100.

[0118] As shown in the figure, Figure 9 Optionally, the lower ends of the first push block 542 and the second push block 543 are respectively provided with avoiding grooves 5413 for avoiding the blade 546. In this way, when the blade 546 is driven by the lifting driving member 544 to descend, the blade 546 can sufficiently extend downward from the first push block 542 and the second push block 543 to cut the spring pipe 100.

[0119] In order to improve the cutting efficiency of the spring pipe, a plurality of (for example, two in the figure) Figures 1 to 3 correspondingly, the first pressing mechanism 3 and the second pressing mechanism 4 can simultaneously press the plurality of spring pipes 100 on the plurality of mounting shafts 2 from both ends. The cutting mechanism 5 can simultaneously cut the plurality of spring pipes 100 on the plurality of mounting shafts 2.

[0120] For the case of two installation shafts 2, as shown in Figure 2 The first pressing mechanism 3 includes two first pressing assemblies 32 corresponding to the installation shafts 2 respectively, the two first pressing assemblies 32 are connected on the driving end of the first translation driving assembly 31 side by side, the first translation driving assembly 31 drives the two first pressing assemblies 32 to slide along the corresponding installation shaft 2 synchronously, so that the two first pressing assemblies 32 press the spring tube 100 on the corresponding installation shaft 2 synchronously.

[0121] As shown in Figure 3 The second pressing mechanism 4 includes two second pressing assemblies 42 corresponding to the installation shafts 2 respectively, the two second pressing assemblies 42 have a common second mounting plate 421, the two second pressing assemblies 42 are connected on the driving end of the second translation driving assembly 41 through the common second mounting plate 421, the second translation driving assembly 41 drives the two second pressing assemblies 42 to slide along the corresponding installation shaft 2 synchronously, so that the two second pressing assemblies 42 press the spring tube 100 on the corresponding installation shaft 2 synchronously. Of course, the two second pressing assemblies 42 can also have the second mounting plate 421 respectively.

[0122] As shown in Figure 5 The cutting mechanism 5 includes two cutting assemblies 54 corresponding to the installation shafts 2 respectively, the two cutting assemblies 54 are arranged on the lifting frame 53 side by side, the lifting driving assembly 52 drives the two cutting assemblies 54 to descend towards the spring tube 100 on the corresponding installation shaft 2 synchronously, so that the two cutting assemblies 54 cut the spring tube 100 on the corresponding installation shaft 2 synchronously.

It should be understood by those skilled in the art that the description in the embodiments is only exemplary, and all changes made without departing from the true spirit and scope of the present application should belong to the protection scope of the present application.
