Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, specifically to an adjustable tube cutting device for plastic products. Background Technology

[0002] Pipe cutting is a common and crucial process in the production and processing of plastic products. Existing plastic pipe cutting equipment often suffers from limited functionality and poor adaptability. Traditional pipe cutting devices typically employ fixed support structures, which struggle to provide effective and stable support for pipes of varying diameters. This can easily lead to skewed cuts, pipe wall deformation, and even safety accidents due to pipe swaying or uneven stress during cutting. Furthermore, conventional devices often use rigid connections between the clamping and cutting components, lacking cushioning and easily damaging the surface of the plastic pipe. The cutting blades also experience wear over time, requiring maintenance and replacement, but these connections are typically secured with bolts and nuts, making disassembly cumbersome and impacting processing efficiency. Therefore, this paper proposes an adjustable pipe cutting device for plastic products. Summary of the Invention

[0003] The purpose of this invention is to provide an adjustable tube cutting device for plastic products to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an adjustable tube cutting device for plastic products, comprising: an operating table; a product support mechanism, the product support mechanism including a support base disposed on the operating table and at least one set of support platforms slidably disposed on the support base; and a fixed cutting mechanism, the fixed cutting mechanism including a U-shaped bracket disposed on the operating table, the U-shaped bracket being provided with a hydraulic cylinder and the telescopic rod of the hydraulic cylinder being provided with a fixing plate, and the fixing plate being provided with a pressing unit and a cutting unit, the pressing unit being disposed above the support platform and being disposed opposite to the support platform.

[0005] As a further preferred embodiment of this technical solution: the support base is provided with a sliding groove for the movement of the support platform.

[0006] As a further preferred embodiment of this technical solution: the support platform includes a slide, and a fixing bolt with an end that can abut against the support is threadedly connected to the side wall of the slide. The slide is also provided with a connecting ball head, and a ball socket is provided on the connecting ball head. A support plate is provided on the ball socket, and a locking bolt with an end that can abut against the connecting ball head is threadedly connected to the side wall of the ball socket.

[0007] As a further preferred embodiment of this technical solution: the clamping unit includes a connecting sleeve fixedly disposed on the bottom surface of the fixed plate, a lifting rod slidably disposed in the connecting sleeve, a clamping plate disposed at the bottom end of the lifting rod, and a spring sleeved on the lifting rod between the clamping plate and the end face of the connecting sleeve.

[0008] As a further preferred embodiment of this technical solution: the cutting unit includes a snap-fit ​​block fixedly mounted on the fixed plate, the snap-fit ​​block having a snap-fit ​​groove and a cutting tool being detachably mounted through the snap-fit ​​groove.

[0009] As a further preferred embodiment of this technical solution: both the support plate and the pressing plate are provided with flexible anti-slip pads with an arc-shaped structure.

[0010] As a further preferred embodiment of this technical solution: the operating table may also be detachably provided with an auxiliary support plate, the top surface of which is an arc-shaped structure.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model achieves flexible support for pipes of different diameters by setting a support platform that can move along the slide groove of the support seat and can be locked by fixing bolts. The support platform adopts a hinge structure that connects the ball head and the ball socket, so that the angle of the support plate can be adjusted in multiple directions, which can adapt to the curvature of the pipe and improve the support stability.

[0013] 2. In this utility model, the clamping unit uses a spring to provide buffer pressure. When the hydraulic cylinder drives the fixing plate to press down, the spring can avoid rigid impact on the pipe and achieve flexible clamping. This can not only firmly fix the pipe but also effectively prevent the pipe surface from deforming or being damaged due to excessive pressure, thus ensuring the integrity of the product. Moreover, the clamping unit and the cutting unit move down synchronously, and the clamping and fixing of the pipe is completed before the cutting action begins. This effectively avoids the rolling or vibration of the pipe during the cutting process, thereby ensuring a flat and vertical cut and significantly improving the cutting quality.

[0014] 3. In this utility model, the cutting unit adopts the cooperation of the snap-fit ​​block and the snap-fit ​​groove to realize the detachable installation of the cutting tool, which eliminates the cumbersome steps of traditional bolt fixing, making the replacement, sharpening or maintenance of the tool extremely convenient, greatly reducing downtime and improving production efficiency.

[0015] 4. The arc-shaped flexible anti-slip pads provided on the support plate and the pressing plate in this utility model increase the friction with the surface of the pipe, further preventing the pipe from sliding during processing. At the same time, the detachable auxiliary support plate can provide additional stable support for the overhanging end of the pipe, preventing the cutting accuracy from being affected by its own weight, and improving the safety and stability of the entire operation process.

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Example 1

[0023] Please see Figures 1-3 This utility model provides a technical solution: an adjustable tube cutting device for plastic products, including an operating table 1, a product support mechanism and a fixed cutting mechanism.

[0024] The product support mechanism includes a support base 2 set on the operating table 1 and at least one set of support platforms that can be slidably set on the support base 2; the fixed cutting mechanism includes a U-shaped bracket 10 set on the operating table 1, a hydraulic cylinder 11 is provided on the U-shaped bracket, a fixed plate 12 is provided on the telescopic rod of the hydraulic cylinder 11, and a pressing unit and a cutting unit are provided on the fixed plate 12. The pressing unit is set above the support platform and can be set opposite to the support platform.

[0025] In this embodiment, specifically: combining Figure 1 As shown, the support base 2 has a sliding groove 4 for moving the support platform. Specifically, the sliding groove 4 is a T-shaped groove or a dovetail groove structure. Correspondingly, the bottom of the support platform is provided with a matching slider, which allows the support platform to slide smoothly along the length of the sliding groove 4 while preventing it from coming off, thus realizing the linear displacement adjustment function of the support platform on the support base 2.

[0026] In this embodiment, specifically: combining Figures 1-2 As shown, the support platform includes a slide 3. A fixing bolt 5, the end of which can abut against the support base 2, is threaded onto the side wall of the slide 3. The slide 3 also has a connecting ball head 6, a ball socket 7, and a support plate 9. A locking bolt 8, the end of which can abut against the connecting ball head 6, is threaded onto the side wall of the ball socket 7. Specifically, the slide 3 achieves a sliding connection by embedding its bottom slider into the sliding groove 4 of the support base 2. When the fixing bolt 5 is tightened, the friction generated at its end can firmly lock the slide 3 in any position on the support base 2. The connecting ball head 6 and the ball socket 7 together form a ball joint, allowing the ball socket 7, together with the support plate 9, to be adjusted in multiple degrees of freedom within a certain cone angle range. This adapts to plastic pipes with different curvatures, ensuring that the support plate 9 fully fits against the outer wall of the pipe. After adjusting to a suitable angle, tightening the locking bolt 8 presses its end against the connecting ball head 6, thus locking the entire support angle.

[0027] In this embodiment, specifically: combining Figure 2 As shown, the clamping unit includes a connecting sleeve 15 fixedly mounted on the bottom surface of the fixed plate 12. A lifting rod 16 is slidably mounted in the connecting sleeve 15, and a clamping plate 18 is mounted at the bottom end of the lifting rod 16. A spring 17 is sleeved on the lifting rod 16 between the clamping plate 18 and the end face of the connecting sleeve 15. Specifically, when the hydraulic cylinder 11 drives the fixed plate 12 to move downward, the clamping plate 18 first contacts the plastic pipe to be cut. Then, the connecting sleeve 15 continues to move downward, compressing the spring 17. The reaction force generated by the spring 17 is continuously applied to the pipe through the clamping plate 18, forming a flexible clamping force with a buffering effect. This effectively avoids rigid impact damage to the surface of the plastic pipe and ensures that the pipe is stably clamped during the cutting process.

[0028] In this embodiment, specifically: combining Figure 1 As shown, the cutting unit includes a snap-fit ​​block 13 fixedly mounted on the fixing plate 12. The snap-fit ​​block 13 has a snap-fit ​​groove through which a cutting blade 14 is detachably mounted. Specifically, the snap-fit ​​groove is slit-shaped, and its width is adapted to the thickness of the cutting blade 14 (such as a blade). During installation, the back of the cutting blade 14 can be directly inserted into the snap-fit ​​groove to achieve fixation; during disassembly, it can be directly pulled out, eliminating the trouble of using bolts or other fasteners, realizing quick replacement of the cutting blade 14, and greatly improving maintenance efficiency.

[0029] In this embodiment, specifically, both the support plate 9 and the clamping plate 18 are provided with flexible anti-slip pads with an arc-shaped structure. Specifically, the flexible anti-slip pads are made of materials with a high coefficient of friction and a certain degree of elasticity, such as rubber or polyurethane. Their top or bottom surfaces are concave arc-shaped surfaces, which can form good surface contact with the outer wall of the circular plastic pipe. On the one hand, this increases the friction force and prevents the pipe from rolling or sliding during cutting; on the other hand, its elasticity protects the outer surface of the pipe from scratches or pressure marks.

[0030] An adjustable tube cutting device for plastic products according to an embodiment of the present invention.

[0031] When using it, first, according to the diameter of the plastic pipe to be cut, loosen the fixing bolts 5 of the slide block 3 on the support platform, move at least two sets of support platforms along the slide groove 4 of the support base 2 to a suitable distance, then tighten the fixing bolts 5 to fix the slide block 3, loosen the locking bolts 8 of the ball socket seat 7, adjust the tilt angle of the support plate 9 so that its arc-shaped anti-slip pad fully fits the lower surface of the pipe, and then tighten the locking bolts 8.

[0032] Next, the plastic pipe is placed on the adjusted support plate 9, and the hydraulic cylinder 11 is activated, causing its telescopic rod to extend downwards. This causes the fixing plate 12, along with the clamping unit and cutting unit mounted on it, to descend together. The flexible anti-slip pad at the bottom of the clamping plate 18 first contacts the upper surface of the pipe. As the fixing plate 12 continues to move downwards, the spring 17 is compressed, and the pipe is flexibly and firmly pressed between the support plate 9 and the clamping plate 18. As the fixing plate 12 continues to descend, the cutting blade 14 mounted on it contacts and is pressed and fixed to the pipe, completing the cutting operation. Because the pipe is fully fixed before cutting, vibration and displacement during the cutting process are effectively avoided, ensuring the quality of the cut.

[0033] After cutting is completed, the hydraulic cylinder 11 retracts, driving the clamping unit and the cutting unit to rise and reset. The operator can then remove the cut pipe section. If the cutting blade 14 is worn, it can be directly pulled out of the clamping slot of the clamping block 13 to replace the new blade. The operation is simple and quick.

[0034] In summary, this utility model achieves flexible, stable, and non-destructive clamping of plastic pipes of various specifications and shapes through the coordinated action of a support platform with adjustable position and angle and a clamping unit with buffer; it enables quick tool replacement through a snap-fit ​​cutting unit; the overall device is flexible to adjust and easy to operate, effectively improving the adaptability, efficiency, and quality of cutting operations.

[0035] Example 2

[0036] Combined with appendix Figure 2 This embodiment is an optimization based on embodiment 1, with the addition of an auxiliary support plate 19.

[0037] In this embodiment, combined with Figure 4 As shown, an auxiliary support plate 19 can also be detachably installed on the operating table 1. The top surface of the auxiliary support plate 19 has an arc-shaped structure. Specifically, the auxiliary support plate 19 is detachably installed on the table surface of the operating table 1 by means of plug-in, snap-on or bolt connection. It is usually located on one or both sides of the support base 2. The arc-shaped structure of its top surface echoes the arc-shaped anti-slip pad on the support plate 9, together forming a longer arc-shaped support surface. The auxiliary support plate 19 itself can be made of rigid plastic or metal. A flexible pad can also be pasted on its arc-shaped top surface to protect the surface of the pipe while providing rigid support. Its main function is to provide effective auxiliary support for the pipe overhang that exceeds the range of the main support base 2, and to prevent sagging caused by the weight of the pipe and vibration during cutting.

[0038] The remaining structure and working principle of this embodiment are exactly the same as those of Embodiment 1. By introducing the auxiliary support plate 19, this utility model not only achieves effective support for the plastic pipe and overcomes the problems of inaccurate positioning and cutting wobbling caused by excessively long overhanging sections, but also improves the operational safety and final cut quality when cutting the pipe, further expanding the processing capacity range of the device.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
