Description

Technical Field

[0001] The utility model relates to the technical field of cutting equipment, in particular to a metal bar cutting device. Background Art

[0002] At present, metal bars need to be cut during production and processing. Cutting is one of the most commonly used processing forms in metal processing. With the development of the economy, the demand for cutting machines is also increasing among some small and medium-sized enterprises. Therefore, it is necessary to optimize the metal bar cutting device.

[0003] For example, a metal bar cutting device is disclosed in the Chinese utility model patent with the publication number CN215966656U. In the above prior art, although the electric lead screw with reverse threads is used to drive two fixed blocks to move towards each other, the metal bar can be accurately centered and clamped. However, the cutting device needs to cut different metal bars. Due to the different metal materials, the wear degree of the cutting blade is also different. It is impossible to calculate and replace the cutting blade according to the wear degree of a single metal bar cutting. When the cutting tool is worn and not replaced in time, the accuracy during cutting will be insufficient, which will directly affect the product quality and processing efficiency. Therefore, it is necessary to design a metal bar cutting device that can detect the wear of the blade. Summary of the Utility Model

[0004] To solve the technical problem that the wear degree of the cutting tool cannot be judged due to cutting different metal bars, the utility model provides a metal bar cutting device.

[0005] The utility model is realized by the following technical solutions: A metal bar cutting device includes a cutting platform. A cutting tool for cutting metal bars is provided on the cutting platform. A detection component for detecting the wear degree of the cutting tool is provided on one side of the cutting tool. A clamping component for clamping and cutting the metal bar is provided on the other side of the cutting tool. The detection component includes a detection box provided on one side of the cutting tool and having a pressure hole, a liquid storage bag provided inside the detection box, and a pressure sensor installed on the top of the detection box through the pressure hole. A detection port adapted to the cutting tool is provided on one side of the detection box. An extrusion port adapted to the cutting tool is provided on one side of the liquid storage bag.

[0006] Through the above technical solutions, after the cutting tool is used for a period of time, the detection component can be used to detect the wear degree of the cutting tool, avoiding overuse of the worn cutting tool.

[0007] As a further improvement of the above solution, limit strips with limit openings are provided on both sides of the detection box. Both of the limit strips are fixedly installed on the cutting platform. Connecting blocks are fixedly installed on both sides of the detection box. One side of each of the two connecting blocks passes through the adjacent limit opening and a limit block is fixedly installed.

[0008] Through the above technical solution, when it is necessary to detect the cutting tool, only by sliding the detection box can it reach the specified position to detect the cutting tool.

[0009] As a further improvement of the above solution, a laser sensor for detecting whether the edge of the cutting tool is damaged is provided on one side of the cutting tool.

[0010] Through the above technical solution, the laser sensor can detect at any time whether there is damage to the cutting part of the cutting tool.

[0011] As a further improvement of the above solution, two sliding grooves are opened on one side of the cutting platform. The clamping assembly includes sliding blocks that are slidably fitted inside each sliding groove, first clamping plates fixedly installed on one side of each sliding block, and second clamping plates rotatably fitted on one side of each first clamping plate. The two first clamping plates and the two second clamping plates are both arranged in a semi-circular ring shape.

[0012] Through the above technical solution, the first clamping plate and the second clamping plate can cooperate to clamp and fix the metal bar.

[0013] As a further improvement of the above solution, replacement grooves are opened on the inner ring surfaces of the two first clamping plates and the two second clamping plates. A replacement block is slidably installed inside each replacement groove. An adapter plate is fixedly installed on one side of each replacement block.

[0014] Through the above technical solution, the adapter plate can be replaced according to the diameter of the metal bar, which is convenient for better clamping of the metal bar.

[0015] As a further improvement of the above solution, fixing plates are fixedly installed on one side of the two sliding blocks and one side of the two second clamping plates. Threaded columns are provided on one side of the two fixing plates that are far away from each other. One end of each of the two threaded columns penetrates through the adjacent fixing plate and is threadedly engaged with the other adjacent fixing plate.

[0016] Through the above technical solution, after the metal bar is clamped, the threaded column and the fixing plate can cooperate to fix the first clamping plate and the second clamping plate.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] The utility model fixes and clamps a metal bar by arranging a detection component and a clamping component. Before cutting the bar, the detection component is used to detect the wear degree of the cutting tool, so as to avoid the excessive wear of the cutting tool affecting the cutting quality. The laser sensor is turned on to detect the cutting part of the cutting tool, preventing the cutting tool from being broken during the cutting process without being discovered in time. Such a setting can not only clamp and fix the metal bar to assist cutting, but also detect the wear degree and fragmentation of the cutting tool, avoiding affecting the cutting quality.

[0024] Next, in combination with the drawings and specific embodiments, the present utility model will be further described. It should be noted that, on the premise of no conflict, any combination of the following-described embodiments or technical features can form a new embodiment.

[0025] Please combine Figures 1 - 3, A metal bar cutting device according to this embodiment includes a cutting platform 1. A cutting knife 2 for cutting metal bars is provided on the cutting platform 1. A detection component for detecting the wear degree of the cutting knife 2 is provided on one side of the cutting knife 2, and a clamping component for clamping and cutting the metal bar is provided on the other side of the cutting knife 2. The detection component includes a detection box 301 provided on one side of the cutting knife 2 and having a pressure hole, a liquid storage bag 302 provided inside the detection box 301, and a pressure sensor 303 installed on the top of the detection box 301 through the pressure hole. The inside of the liquid storage bag 302 can be a liquid that is not easily compressed, such as water or oil. A detection port adapted to the cutting knife 2 is provided on one side of the detection box 301, and an extrusion port adapted to the cutting knife 2 is provided on one side of the liquid storage bag 302. Limit strips 5 with limit ports are provided on both sides of the detection box 301. Both limit strips 5 are fixedly installed on the cutting platform 1. Connecting blocks 6 are fixedly installed on both sides of the detection box 301. On one side of each of the two connecting blocks 6, a limit block 7 is fixedly installed after passing through the adjacent limit port. After the cutting knife 2 is used for a period of time, the detection component can be used to detect the wear degree of the cutting knife 2 to avoid using the cutting knife 2 when it is overly worn. When it is necessary to detect the cutting knife 2, only by sliding the detection box 301 can it reach the specified position to detect the cutting knife 2.

[0026] Combined with Figure 1 , A laser sensor 8 for detecting whether the edge of the cutting knife 2 is damaged is provided on one side of the cutting knife 2. The laser sensor 8 can detect at any time whether there is damage to the cutting part of the cutting knife 2.

[0027] Combined with Figure 1 and Figure 2 , Two sliding grooves are provided on one side of the cutting platform 1. The clamping component includes sliding blocks 401 that are slidably engaged inside each sliding groove, first clamping plates 402 fixedly installed on one side of each sliding block 401, and second clamping plates 403 rotatably engaged on one side of each first clamping plate 402. The two first clamping plates 402 and the two second clamping plates 403 are both arranged in a semi-circular ring shape. Replacement grooves are provided on the inner ring surfaces of the two first clamping plates 402 and the two second clamping plates 403. Replacement blocks 9 are slidably installed inside each replacement groove. An adapter plate 10 is fixedly installed on one side of each replacement block 9. Fixing plates 11 are fixedly installed on one side of the two sliding blocks 401 and one side of the two second clamping plates 403. Threaded columns 12 are provided on one side of the two fixing plates 11 that are far away from each other. One end of each of the two threaded columns 12 passes through the adjacent fixing plate 11 and is threadedly engaged with the other adjacent fixing plate 11. The first clamping plate 402 and the second clamping plate 403 can cooperate to clamp and fix the metal bar. The adapter plate 10 is replaced according to the diameter of the metal bar to facilitate better clamping of the metal bar. After the metal bar is clamped, the threaded column 12 and the fixing plate 11 can cooperate to fix the first clamping plate 402 and the second clamping plate 403.

[0028] In the embodiment of the present application, the implementation principle of a metal bar cutting device is as follows: When cutting a metal bar, open the two second clamping plates 403, pull out the plurality of replacement blocks 9, and thus the adapter plate 10 is removed. Replace the adapter plate 10 that is adapted to the bar to be cut, then place the metal bar and close the second clamping plate 403, and use the threaded column 12 for limiting and fixing. Before starting the cutting, slide the detection box 301 to the end of the limit port, so that a part of the cutting knife 2 can be placed into the detection box 301, and the extrusion port of the liquid storage bag 302 will also wrap the cutting knife 2 to ensure that the degree of the cutting knife 2 entering the detection box 301 is the same each time. If the cutting knife 2 is worn out excessively, the force exerted on the liquid storage bag 302 by extrusion will be small, because the cutting knife 2 is worn and its volume becomes smaller than the original, and the more worn it is, the smaller the volume and the smaller the extrusion force on the liquid storage bag 302. In this way, the pressure sensor 303 will obtain the data of the extrusion, and compare it with the worn data that needs to be replaced. If it does not reach the standard, it can continue to be used; if it reaches the standard, it needs to be replaced. After the detection is completed, start the cutting knife 2, and start the laser sensor 8 to detect the cutting edge of the cutting knife 2 to prevent damage to the edge of the cutting knife 2. In this way, the metal bar can be cut. Such a setting can not only clamp and fix the metal bar to assist in cutting, but also detect the wear degree and fragmentation of the cutting knife 2 to avoid affecting the cutting quality.

[0029] The above-mentioned implementation manner is only the preferred implementation manner of the present utility model, and cannot be used to limit the scope of protection of the present utility model. Any non-substantial changes and substitutions made by those skilled in the art based on the present utility model fall within the scope of protection required by the present utility model.
