Description

Technical Field

[0001] The utility model belongs to the field of processing of products, and particularly relates to a cutting device for reducing tail materials. Background Art

[0002] In industrial production, cutting devices are usually used to cut materials such as pipe materials to meet the production requirements of different lengths of pipe materials. The most prominent problem with existing cutting devices is that there is a lot of tail material residue. Since a cutting mechanism and a positioning mechanism for stabilizing the cutting of the pipe material need to be provided on the production equipment, and a clamping and fixing mechanism is also required for the feeding mechanism to convey the pipe material, these mechanisms are arranged in sequence on the machine frame, resulting in too long a distance between the tail material of the pipe material and the cutting tool all the time, and the remaining length of the tail material is too long, which can only be treated as waste. This leads to serious waste and high production costs, causing material waste and increased treatment costs. Therefore, there is an urgent need in this field for a cutting device for reducing tail materials. Summary of the Utility Model

The plane heights of the first roller and the second roller in contact with the pipe material are both slightly higher than the height of the upper surface of the mounting base.

[0009] Preferably, the Y-axis pressing member includes a Y-axis driving cylinder, a connecting plate fixed to the output end of the Y-axis driving cylinder, and a side pressing plate mounted on the connecting plate.

[0010] Preferably, the side pressing plate is detachably mounted on the connecting plate.

[0011] Preferably, the material supporting mechanism includes a bottom plate and a supporting plate. A Y-axis slide rail is provided on the bottom plate. A material supporting slider is slidably arranged on the Y-axis slide rail. A material supporting inclined rail is installed on the top of the material supporting slider.

When the reference plate descends to the lowest point, the height of its top end is lower than the height of the lower surface of the mounting base.

[0014] (3) Beneficial effects

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] In the state where the cutting device is not started, the feeding mechanism is located at the feeding end of the frame. The pipe material enters above the frame along the X-axis from the feeding end and passes through the feeding mechanism. When the cutting device is started, the feeding mechanism clamps the pipe material and moves it in the direction close to the cutting mechanism. When one end of the pipe material moves through the cutting gap and reaches the position of the predetermined cutting length, the feeding mechanism stops moving. The first limiting component and the second limiting component simultaneously press down on the pipe material. Subsequently, the cutting mechanism is started and moves along the Y-axis direction to cut the pipe material. After the cutting is completed, the first limiting component and the second limiting component are lifted and reset, and the feeding mechanism continues to move repeatedly until the feeding mechanism moves near the material supporting mechanism. The first limiting component rises and the material supporting mechanism descends to avoid the feeding mechanism. At this time, the feeding mechanism can move near the cutting mechanism to cut the tail material, thereby reducing the remaining length of the tail material, increasing the yield, and avoiding the waste of cost caused by too long tail material.

[0024] It should be noted that all directional indications such as up, down, left, right, front, back... in the embodiments of this application are only used to explain the relative position relationship and movement conditions between components in a specific posture as shown in the accompanying drawings. If this specific posture changes, then the directional indications will also change accordingly.

[0025] In addition, in this application, descriptions such as "first" and "second" are only for descriptive purposes, and do not particularly refer to the order or sequence. Nor are they used to limit this application. They are only used to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those skilled in the art can implement them. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by this application.

[0026] To further understand the inventive content, features and effects of the present application, the following embodiments are exemplified and described in detail with reference to the accompanying drawings as follows.

[0027] Please refer to Figures 1-4 , the utility model provides a cutting device for reducing tail stock, which includes a frame 1, a pinch feeding mechanism 2, a cutting mechanism 3 and a supporting mechanism 4. The clamping mechanism clamps and transfers materials between the feeding end 11 and the cutting gap 12 of the frame 1 along the X-axis direction. The cutting mechanism 3 is installed in the cutting gap 12 of the frame 1 and moves along the Y-axis direction for cutting. On both sides of the cutting mechanism 3, there are a first limiting component 51 and a second limiting component 52 for pressing and limiting materials. A supporting mechanism 4 is arranged in a lifting manner directly below the first limiting component 51. When the clamping mechanism moves to a position adjacent to the supporting mechanism 4, the first limiting component 51 rises and the supporting mechanism 4 descends.

[0028] In the state where the cutting device is not started, the pinch feeding mechanism 2 is located at the feeding end 11 of the frame 1. The pipe material enters above the frame 1 along the X-axis from the feeding end 11 and passes through the pinch feeding mechanism 2. When the cutting device is started, the pinch feeding mechanism 2 clamps the pipe material and moves it towards the cutting mechanism 3. When one end of the pipe material moves through the cutting gap 12 and reaches the position of the predetermined cutting length, the pinch feeding mechanism 2 stops moving. The first limiting component 51 and the second limiting component 52 simultaneously press down on the pipe material. Subsequently, the cutting mechanism 3 is started and moves along the Y-axis direction to cut the pipe material. After cutting, the first limiting component 51 and the second limiting component 52 are lifted and reset. The pinch feeding mechanism 2 continues to move in this way repeatedly until the pinch feeding mechanism 2 moves near the supporting mechanism 4. The first limiting component 51 rises and the supporting mechanism 4 descends to avoid the pinch feeding mechanism 2. At this time, the pinch feeding mechanism 2 can move near the cutting mechanism 3 to cut the tail stock, thereby reducing the remaining length of the tail stock, increasing the yield rate, and avoiding the waste of cost caused by too long tail stock.

[0029] On both sides of the frame 1 in the embodiment of the present utility model, two X-axis slide rails 13 are provided in parallel. The feeding mechanism 2 includes an X-axis slider 21 slidably mounted on the X-axis slide rail 13, a mounting seat 22 fixed on the X-axis slider 21, a Z-axis pressing member 23 and a Y-axis pressing member 24 mounted on the mounting seat 22. A support plate 221 is provided on one side of the mounting seat 22 corresponding to the X-axis slide rail 13. The upper end of the support plate 221 is fixedly connected to the Z-axis pressing member 23. The Z-axis pressing member 23 is located directly above the mounting seat 22. The Y-axis pressing member 24 is mounted on the upper surface of the mounting seat 22. By providing the support plate 221 and connecting the top end of the support plate 221 to the Z-axis pressing member 23, the Z-axis pressing member 23 is supported and lifted and suspended directly above the mounting seat 22. When the pipe material enters the feeding mechanism 2, the Z-axis pressing member 23 and the Y-axis pressing member 24 will push the pipe material from two directions until the lower surface of the pipe material is in close contact with the upper surface of the mounting seat 22 and the side of the pipe material is in close contact with the support plate 221. At this time, the clamping action of the feeding mechanism 2 on the pipe material is completed. Subsequently, when the feeding mechanism 2 moves along the X-axis direction, it drives the pipe material to move towards the cutting mechanism 3, thereby completing the feeding action of the pipe material.

[0030] During the process of the pipe material entering the feeding mechanism 2, in order to prevent the lower end of the pipe material from rubbing against the mounting seat 22 and causing wear on the surface of the material, which affects the product quality, a first roller 222 is provided on one side of the mounting seat 22 close to the feeding end 11 of the frame 1. A second roller 111 is provided on the feeding end 11 of the frame 1. A liftable movable roller 14 is provided in the middle of the frame 1. The height of the plane where the movable roller 14 contacts the pipe material when it is lifted to the highest point is slightly higher than the height of the upper surface of the mounting seat 22. The height of the movable roller 14 when it descends to the lowest point is lower than the height of the lower surface of the mounting seat 22. The height of the planes where the first roller 222 and the second roller 111 contact the pipe material is slightly higher than the upper surface of the mounting seat 22. When the feeding mechanism 2 is located at the feeding end 11 of the frame 1, the movable roller 14 remains in the upwardly lifted state. Therefore, when the pipe material moves onto the frame 1, it is carried by the first roller 222, the second roller 111 and the movable roller 14, and there will be no frictional contact with the upper surface of the mounting seat 22 during this process, ensuring the product quality.

[0031] It should be noted that while considering avoiding friction between the bottom surface of the pipe material and the upper surface of the mounting base 22 during movement, it is also necessary to consider that the pipe material needs to maintain a relatively parallel state during cutting by the cutting mechanism 3 to avoid oblique cutting. Therefore, when all the rollers in the embodiment of the present utility model lift the pipe material relative to the mounting base 22, the height spacing between the bottom surface of the pipe material and the upper surface of the mounting base 22 should not be too large. Therefore, the expression of its height limit is "slightly higher". This expression does not mean unclear. How much higher specifically is a small distance that those skilled in the art need to comprehensively consider according to factors such as the material and weight of the pipe material in actual production. Numerical limitations are not described here. Expressing it as "slightly higher" is for rigor to avoid affecting normal cutting due to too large a height difference and thus causing new production problems.

[0032] The Y-axis pressing member 24 in the embodiment of the present utility model includes a Y-axis driving cylinder 241, a connecting plate 242 fixed to the output end of the Y-axis driving cylinder 241, and a side pressing plate 243 mounted on the connecting plate 242. The Z-axis pressing member 23 includes a first lifting assembly 231 and a second lifting assembly 232 that are synchronously lifted and lowered on both sides of the Y-axis driving cylinder 241. The first lifting assembly 231 includes a first hanging plate 2311 fixedly connected to the upper end of the support plate 221, a first cylinder 2312 fixedly installed on the first floating plate, and a first pressing plate 2313 fixed to the output end of the first cylinder 2312. The second lifting assembly 232 includes a second hanging plate 2321 fixedly connected to the upper end of the support plate 221, a second cylinder 2322 fixedly installed on the second hanging plate 2321, and a second pressing plate 2323 fixed to the output end of the second cylinder 2322. The first pressing plate 2313 and the second pressing plate 2323 always remain at the same horizontal height. When the pipe material needs to be clamped and fed, the first cylinder 2312, the second cylinder 2322, and the Y-axis driving cylinder 241 drive the first pressing plate 2313, the second pressing plate 2323, and the side pressing plate 243 to move simultaneously, so as to realize the clamping and fixing of the pipe material.

[0033] When clamping and feeding pipe materials of different specifications, the moving distances of the first pressing plate 2313, the second pressing plate 2323, and the side pressing plate 243 need to be adjusted accordingly. Since the second pressing plate 2323 presses downward above the side pressing plate 243, when clamping and feeding a pipe material with a relatively small diameter, in order to avoid the second pressing plate 2323 pressing on the side pressing plate 243, it is necessary to make an adaptive adjustment to the specification size of the side pressing plate 243. Therefore, the side pressing plate 243 in the embodiment of the present utility model is detachably installed on the connecting plate 242, so as to replace and use side pressing plates 243 of different specifications according to the specifications of the pipe material.

[0034] In the embodiment of the present utility model, the material supporting mechanism 4 includes a bottom plate 41 and a supporting plate 43. A Y-axis slide rail 411 is provided on the bottom plate 41. A material supporting slide block 412 is slidably arranged on the Y-axis slide rail 411. A material supporting inclined rail 413 is installed on the top of the material supporting slide block 412. An inclined rail slide block 414 is slidably arranged on the material supporting inclined rail 413. The top of the inclined rail slide block 414 is connected to an inclined plate 415. The top of the inclined plate 415 is fixedly connected to the bottom of the supporting plate 43. Z-axis guiding sliding members 44 are provided at both ends of the supporting plate 43. A ball screw pair 45 and a material supporting driving motor 46 for driving the ball screw pair 45 to move are arranged on one side of the bottom plate 41. The moving end of the ball screw pair is connected to and fixed to one side of the material supporting slide block 412. When the material supporting driving motor 46 drives the moving end of the ball screw pair 45 to move, the material supporting slide block 412 fixedly connected to this moving end slides on the Y-axis slide rail 411, driving the material supporting inclined rail 413 on the material supporting slide block 412 to move synchronously. Furthermore, the relative position of the inclined rail slide block 414 on the material supporting inclined rail 413 changes accordingly, and its height in the Z-axis also changes. The inclined rail slide block 414 drives the height of the inclined plate 415 in the X-axis direction to change, and further drives the supporting plate 43 to move up and down. By setting the liftable and movable supporting plate 43, the avoidance action of the mounting seat 22 on the clamping and feeding mechanism 2 is realized.

[0035] In the embodiment of the present utility model, the first limiting component 51 and the second limiting component 52 both press down the pipe material synchronously when the supporting plate 43 of the material supporting mechanism 4 is in the lifted state. Thus, during the process of the cutting mechanism 3 cutting the pipe material, both ends of the cutting position are pressed and limited, avoiding the pipe material from shifting during cutting and causing cutting deviation, reducing the probability of defective products flowing out, and improving the quality of the product and the stability of production. The first limiting component 51 rises synchronously and then remains stationary when the supporting plate 43 descends. The second limiting component 52 normally lifts and presses the material. It should be noted that the driving and lifting principle and structure of the first limiting component 51 and the second limiting component 52 are the same as those of the Y-axis pressing member 24, and no detailed description will be given here.

[0036] In the embodiment of the utility model, a reference plate 15 is arranged in the middle of the frame 1 in a lifting manner. The reference plate 15 is located on the side of the movable roller 14 close to the cutting mechanism 3. A reference driving cylinder 151 for driving the lifting of the reference plate 15 is arranged in the frame 1. When the reference plate 15 is lifted to the highest point, the height of its top end is higher than the height of the upper surface of the mounting seat 22. When the reference plate 15 descends to the lowest point, the height of its top end is lower than the height of the lower surface of the mounting seat 22. When the clamping mechanism 2 is located at the feeding end 11 of the frame 1, the reference driving cylinder 151 drives the reference plate 15 to rise to a position higher than the height of the movable roller 14. The pipe material enters the frame 1, passes through the clamping mechanism 2 until one end of the pipe material abuts against the reference plate 15. At this time, the pipe material cannot move further. Subsequently, the clamping mechanism 2 clamps the pipe material. At the same time, the reference plate 15 descends to avoid interference. After the clamping mechanism 2 completes the clamping action and moves, the feeding action can be executed. By setting the liftable reference plate 15, the feeding depth of the pipe material is limited to avoid the pipe material rubbing against the cutting mechanism 3 due to too deep feeding, resulting in defective products.

[0037] The above description is only a preferred embodiment of the present application, and does not impose any form of limitation on the present application. Any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present application shall fall within the scope of the technical solution of the present application.
