Description

Technical Field

[0001] The invention relates to the technical field of corrugated pipe processing equipment, in particular to a variable fixed-length cutting machine for corrugated pipes. Background Art

[0002] As a flexible product, bellows are widely used in various industrial fields, including automobile, construction, electronics and other industries. However, the existing bellows cutting technology has many shortcomings, which seriously affect the production efficiency and product quality.

[0003] First, the existing corrugated tube cutting machine mainly uses a visual camera as a single positioning device. Since the corrugated tube is a flexible material, it is easy to stretch and deform during the transmission process, which makes it difficult for the visual camera to accurately locate the position of the corrugated tube, making it difficult to achieve fixed-length cutting. This inaccurate positioning problem will lead to inconsistent cutting lengths, affecting the quality and consistency of the product.

[0004] Secondly, the loading and unloading systems of existing corrugated pipe cutting machines are usually located on the same side. After cutting, the cut corrugated pipe needs to be removed from the machine manually or mechanically before the next cutting operation can be performed. This design leads to discontinuity and inefficiency in the production process and cannot meet the needs of mass production.

[0005] In addition, the existing corrugated pipe cutting machine lacks the classification and storage function, and the corrugated pipes cut into different lengths are usually mixed and stacked together. When they are subsequently processed or used, they need to be manually sorted, which not only increases the labor intensity of the workers, but also seriously affects the processing efficiency of the corrugated pipes.

DETAILED DESCRIPTION

[0059] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0060] Example 1

[0061] See also Figure 1-3A variable fixed-length cutting machine for corrugated pipes includes a feeding component 1, a positioning and cutting component 2, a blanking component 3, and a visual camera 4. The feeding component 1 and the blanking component 3 are arranged on both sides of the positioning and cutting component 2. The feeding component 1 is used for feeding the corrugated pipe and transmitting it to the positioning and cutting component 2. The visual camera 4 is arranged above the positioning and cutting component 2. The visual camera 4 cooperates with the positioning and cutting component 2 to position and cut the corrugated pipe. The blanking component 3 is used to receive the cut corrugated pipe and blank it.

[0062] The positioning and cutting assembly 2 includes a main slide 21, an auxiliary slide 22, a retractable assembly, a positioning module, and a cutter assembly 25. The main slide 21 and the auxiliary slide 22 are slidably mounted, the retractable assembly is dynamically connected to the main slide 21 and the auxiliary slide 22, the sliding directions of the main slide 21 and the auxiliary slide 22 are perpendicular to the transmission direction of the bellows, the positioning module is mounted on the main slide 21, the main slide 21 and the auxiliary slide 22 are both equipped with a main clamp 26 and an auxiliary clamp 27, the positioning module is linked to the auxiliary clamp 27, and the main clamp 26 and the auxiliary clamp 27 are both equipped with a cutter assembly 25.

[0063] When the corrugated tube is cut to a fixed length, the corrugated tube is input from one side of the feeding component 1, and the feeding component 1 drives the corrugated tube to be stably transmitted to the positioning and cutting component 2. After the corrugated tube is sent to the fixed length position of the positioning and cutting component 2 as required, since the corrugated tube is a flexible product, the corrugated tube is stretched to a certain extent during the feeding process driven by the feeding component 1, and the accuracy standard cannot be met. At this time, the visual camera 4 is started to take pictures, and the characteristic plane coordinates of the cutting position are sent to the controller (mostly a PLC controller) by communication. After receiving the coordinates, the controller converts them into actual distance deviations and sends instructions to the positioning module, which drives the sub-clamp 27 to run to the actual cutting position.

[0064] Afterwards, the main slide 21 and the auxiliary slide 22 are driven by the retracting and extending assembly to move toward each other, so that the main clamp 26 and the auxiliary clamp 27 on them are brought together to clamp and fix the corrugated tube therein, and the cutter assembly 25 in the auxiliary clamp 27 is started to cut the actual cutting position on the corrugated tube. The cut corrugated tube is received by the unloading assembly 3 and the unloading operation is completed.

[0065] The visual camera 4, the feeding assembly 1, the main clamp 26 and the cutter assembly 25 assembled therein can also cooperate to complete the rapid cutting of the corrugated pipe. At this time, the feeding assembly 1 transports the corrugated pipe to the positioning and cutting assembly 2, and the visual camera 4 takes pictures and positions the corrugated pipe directly below it, including the coordinates of the characteristic points of the corrugated pipe joint obtained by static and dynamic photography, and uses the coordinates of the characteristic points as the initial point for length measurement. During the continuous feeding process of the feeding assembly 1, the length distance from the position of the corrugated pipe joint to the position of the main clamp 26 is calculated, and the position of the main clamp 26 is used as the cutting position of the corrugated pipe. The retractable assembly is controlled to drive the main clamp 26 and the auxiliary clamp 27 to close to fix the corrugated pipe, and the cutter assembly 25 in the main clamp 26 is started to cut the corrugated pipe to a fixed length.

[0066] The cutter assembly 25 in the main clamp 26 and the auxiliary clamp 27 can also be controlled to operate simultaneously to cut the edge distance of the corrugated tube. The auxiliary clamp 27 can operate with the positioning module to adjust the distance between it and the main clamp 26, thereby adjusting the length of the cut portion.

[0067] In order to ensure that the above-mentioned components can be assembled and operated stably, and to ensure that the feeding component 1, the positioning and cutting component 2, the unloading component 3, and the visual camera 4 cooperate to complete the fixed-length cutting of the corrugated pipe, the following technical solution is provided.

[0068] It also includes a machine table 5, on which a hood 51 is fixedly mounted. The feeding assembly 1, the positioning and cutting assembly 2, and the unloading assembly 3 are all assembled on the machine table 5 and arranged in the hood 51. The visual camera 4 is fixedly installed on the top of the hood 51 and arranged vertically downward.

[0069] The setting of the machine platform 5 can ensure the stable installation of all the components involved. The machine cover 51 can ensure the stable installation of the visual camera 4 while ensuring the stable operation of the feeding component 1, the positioning and cutting component 2, and the unloading component 3 therein, and prevent the debris generated during the corrugated tube cutting process from splashing outward.

[0070] A vertically arranged mounting partition 52 is provided on the machine cover 51, which can separate the driving part and the acting part of the feeding component 1 and the positioning and cutting component 2 to both sides of the mounting partition 52, so as to ensure that the acting part and the unloading component 3 on one side of the mounting partition 52 can perform operations such as feeding, positioning, cutting and unloading on the corrugated pipe, and ensure that the driving part of the feeding component 1 and the positioning and cutting component 2 on the other side of the mounting partition 52 can work stably to drive the operation of the acting part.

[0071] In order to ensure that the corrugated tube can be stably transported into the hood 51 and received and transmitted by the feeding assembly 1, and to ensure that the cut corrugated tube can be stably output to the outside of the hood 51 through the unloading assembly 3, the following technical solution is provided.

[0072] A feeding port 511 and a unloading port 512 are respectively provided on both sides of the machine hood 51. The feeding component 1 is arranged on the side close to the feeding port 511, and the unloading component 3 is arranged on the side close to the unloading port 512. A connecting seat A531 is fixedly installed in the machine hood 51, and a feed guide cylinder 53 arranged in the feeding port 511 is fixedly installed on the connecting seat A531.

[0073] The connecting seat A531 is fixedly mounted on the mounting partition 52, and the feed guide cylinder 53 is fixed to the connecting seat A531 by fastening bolts. The bellows is loaded with materials through the feed port 511, and is transported to the feed component 1 by the feed guide cylinder 53, and is received by the feed component 1 and transmitted to the positioning and cutting component 2.

[0074] The feed guide cylinder 53 is designed as a tapered through-cavity structure with a wide port and a narrow interior, which can ensure that the bellows can quickly pass through the feed guide cylinder 53 and be initially positioned so that it can be stably received by the feeding assembly 1 .

[0075] The corrugated tube cut by the positioning and cutting assembly 2 is received by the blanking assembly 3 and output to the outside of the hood 51 through the blanking opening 512, thus completing the blanking work.

[0076] Example 2

[0077] See also Figure 3-8 In order to ensure that the feeding assembly 1 can be stably installed on the machine table 5, ensure that the feeding assembly 1 can clamp the corrugated tube in place, and stably transfer the corrugated tube to the positioning and cutting assembly 2, the following technical solution is provided.

[0078] The feeding assembly 1 includes an assembly bracket 11, a lifting frame plate 12, an adjusting screw A13, a motor A14, a transmission assembly 15, and a motor B16.

When the motor A14 drives the adjusting screw A13 to rotate, it can drive the two sets of lifting frame plates 12 and the transmission components 15 assembled on the lifting frame plates 12 to maintain symmetrical movement, thereby making the two sets of transmission components 15 move closer to or away from each other, and the center line between the two sets of transmission components 15 overlaps with the axis of the feed guide tube 53, so as to ensure that the threaded pipe input by the feed guide tube 53 can be stably clamped by the two sets of transmission components 15.

[0082] When the two sets of transmission components 15 are driven by the motor B16 to run, the threaded pipe between them can be internally transmitted to the directional cutting component.

[0087] A positioning seat 124 is also fixedly mounted on the lifting frame plate 12, and a tensioning wheel 154 and part of the supporting wheel 153 are rotatably mounted on the positioning seat 124. The height position of the tensioning wheel 154 is adjustable to keep the transmission belt 155 arranged on the periphery in a taut state, and the height position of the tensioning wheel 154 is locked and positioned by a locking nut.

The transition guide tube 54 is fixedly mounted on the connecting seat B541, and the connecting seat B541 is fixedly mounted on the mounting partition 52. The transition guide tube 54 is arranged on the center line of the main clamp 26 and the auxiliary clamp 27. The corrugated tube transmitted from the feeding assembly 1 passes through the transition guide tube 54 and is stably transmitted to between the main clamp 26 and the auxiliary clamp 27.

[0098] In order to ensure that the main clamp 26 and the auxiliary clamp 27 can be stably assembled on the main slide 21 and the auxiliary slide 22, and to ensure that the positioning module can be stably installed on the main slide 21 and drive the auxiliary clamp 27 to move synchronously along the transmission direction of the corrugated tube, the following technical solution is provided.

[0103] The arrangement direction of the wedge-shaped guide rail 2711 and the wedge-shaped guide groove 2721 is perpendicular to the transmission direction of the corrugated tube, and can prevent the wedge-shaped guide groove 2721 and the wedge-shaped guide rail 2711 from derailing at an angle perpendicular to the arrangement direction. Therefore, when the auxiliary clamp seat A271 is driven by the sliding frame 243 to move forward, the wedge-shaped guide rail 2711 can drive the wedge-shaped guide groove 2721 and the auxiliary clamp seat B272 to move synchronously.

[0111] The guide frame 252 and the blade 253 can be driven by the telescopic cylinder B251 to telescope, so that the guide frame 252 and the blade 253 can be telescoped along the angle perpendicular to the transmission direction of the corrugated pipe. The setting of the guide groove A263 and the guide groove B274 can ensure that the corresponding guide frame 252 and the blade 253 can pass through the main clamp 26 and the auxiliary clamp 27 and effectively cut the corrugated pipe positioned therein.
