Description

Technical Field

[0001] This utility model relates to the field of profile cutting technology, and in particular to a cutting mechanism for a blanking machine. Background Technology

[0002] A cutting machine is a device that cuts profiles into blocks according to set dimensions. It typically includes a feeding mechanism, a cutting mechanism, and a discharging mechanism. The feeding mechanism feeds the profiles to the cutting mechanism, which cuts the profiles into the desired products according to the set dimensions. The discharging mechanism transports the desired products to a designated location.

[0003] In actual production and processing, a single profile can typically be cut into multiple desired products. After one cut, the cutting mechanism can convey the profile for further cutting. However, if the remaining portion after multiple cuts is insufficient to form another desired product, this remaining portion needs to be removed. Existing blanking machines lack the ability to autonomously determine whether the remaining profile is suitable for cutting, requiring manual judgment, which leads to low automation and production efficiency.

[0004] Therefore, a structure needs to be developed to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a cutting mechanism for a blanking machine to solve the problems existing in the prior art. It can detect whether there is profile in the first clamping area, and combined with the displacement monitoring mechanism, it can detect the length of the remaining profile. This can improve the accuracy of judging the length of the remaining profile, and eliminate the need for other mechanisms or manual removal of the remaining profile, which is conducive to improving the continuity of the processing and production efficiency.

[0006] This utility model provides a cutting mechanism for a blanking machine, including a frame and a cutting machine and a clamping assembly mounted on the frame. The clamping assembly includes a first clamping seat, a first clamping plate, and a second clamping plate. The first clamping seat is fixedly connected to the output end of a first horizontal drive mechanism, and the moving direction of the first clamping seat is parallel to the rotation axis of the saw blade in the cutting machine. In a horizontal direction perpendicular to the moving direction of the first clamping seat, the first clamping plate is vertically fixed to one end of the first clamping seat near the cutting machine. The second clamping plate is positioned opposite the first clamping plate and is fixedly connected to the output end of a second horizontal drive mechanism, allowing the second clamping plate to move closer to or further away from the first clamping plate. A first clamping area for clamping profiles is provided between the first clamping plate and the second clamping plate. The second clamping plate is also provided with a profile detection component for determining whether there are profiles in the clamping area. The cutting mechanism also includes a displacement monitoring mechanism for monitoring the displacement of the first clamping seat.

[0007] In one embodiment, the profile detection assembly includes a rotating rod and an abutting post. The rotating rod is rotatably mounted on the top of the second clamping plate via a vertically arranged rotating shaft. The abutting post is vertically connected to the end of the rotating rod near the cutting machine. The rotating shaft is connected to an elastic element, which is used to impede the rotation of the rotating shaft. If there is no profile in the first clamping area, the abutting post extends into the first clamping area under the action of the elastic element. If there is a profile in the first clamping area, the end face of the second clamping plate and the side wall of the abutting post are both in close contact with the wall of the profile.

[0008] As one embodiment, a plurality of bearings are rotatably mounted on the abutting post from top to bottom, and the bearings are used to abut against the wall surface of the profile.

[0009] As one embodiment, it also includes a support plate and a second clamping seat disposed on the frame. The support plate and the second clamping seat are both located on the radial side of the upper saw blade of the cutting machine. The second clamping seat is provided with a lifting drive mechanism and a lower pressure plate fixed to the lifting end of the lifting drive mechanism. The lower pressure plate is located above the support plate and is used to press the profile onto the support plate.

[0010] As one embodiment, a third clamping plate is vertically arranged on the side of the support plate near the saw blade. The frame is also provided with a third horizontal drive mechanism and a fourth clamping plate disposed at the moving end of the third horizontal drive mechanism. The fourth clamping plate is directly opposite the third clamping plate, and a second clamping area is formed between the fourth clamping plate and the third clamping plate. The third clamping plate and the lower pressure plate are used to clamp the profile in the second clamping area.

[0011] As one embodiment, the third clamping plate is provided with a slit for the saw blade to pass through.

[0012] In one embodiment, the base of the cutting machine is fixedly connected to the output end of the fourth horizontal drive mechanism, which is used to drive the cutting machine closer to or further away from the second clamping area.

[0013] As one embodiment, the first horizontal drive mechanism is a ball screw mechanism, and the first clamping seat is fixedly connected to the balls in the ball screw mechanism; the second horizontal drive mechanism, the third horizontal drive mechanism, the fourth horizontal drive mechanism, and the lifting drive mechanism are hydraulic cylinders or pneumatic cylinders.

[0014] As one embodiment, the frame is also provided with a head end detector for detecting the head end position of the profile.

[0015] This utility model also provides a cutting method for a blanking machine. Based on the above-mentioned cutting mechanism, the cutting method includes the following steps: The feeding mechanism of the unloading machine transports the profile to the first clamping area, and the second horizontal drive mechanism pushes out the second clamping plate, and the first clamping plate and the second clamping plate clamp the profile. The first horizontal drive mechanism pushes the first clamping seat and the profile toward the cutting machine. After the head end detector detects the head end of the profile, it records the current position of the head end of the profile. The first horizontal drive mechanism continues to work and conveys the profile forward. When the profile reaches the cutting position, the third horizontal drive mechanism pushes the fourth clamping plate to extend and clamp the profile horizontally. The lifting drive mechanism works and the lower pressure plate descends to vertically press the profile. The fourth level drive mechanism operates, pushing the cutting machine to move and cut the profile; after cutting is completed, the cutting machine retracts. The second clamping plate loosens the profile, the first clamping seat retracts a set distance, re-clamps the profile, and then the profile is conveyed forward again for cutting. Repeat this process; When the first clamping seat retracts a set distance, during the clamping process of the second clamping plate, if the profile detection component detects that there is no profile in the first clamping area, the first clamping seat moves forward under the action of the second horizontal drive mechanism until the profile detection component detects the profile. At this time, the displacement monitoring mechanism can determine the remaining length of the profile based on the moving distance of the second clamping plate. If the remaining length of the profile is sufficient for one cut, the second clamping plate re-clamps the profile and uses the first horizontal drive mechanism to drive the profile forward for cutting. If the remaining length of the profile is insufficient for one cut, the material is reloaded, and the first horizontal drive mechanism pushes out the remaining part of the previous profile when conveying the next profile.

[0016] Beneficial effects: This invention, by setting a profile detection component on the second clamping plate, can detect whether there is a profile in the first clamping area. Combined with a displacement monitoring mechanism, it can detect the length of the remaining profile, thereby determining whether the remaining profile can be cut again for subsequent instructions. This not only improves the accuracy of judging the length of the remaining profile, but also allows the remaining profile to be pushed out by the conveying of the next profile using the first horizontal drive mechanism, without the need for other mechanisms or manual removal of the remaining profile, which is beneficial to improving the continuity of the processing and production efficiency.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] The purpose of this utility model is to provide a cutting mechanism and cutting method for a blanking machine to solve the problems existing in the prior art. It can detect whether there is profile in the first clamping area, and combined with the displacement monitoring mechanism, it can detect the length of the remaining profile. It can improve the accuracy of judging the length of the remaining profile, without the need to use other mechanisms or manual removal of the remaining profile, which is conducive to improving the continuity of the processing process and production efficiency.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1: like Figures 1-5 As shown, this embodiment provides a cutting mechanism for a feeder, including a frame 1 and a cutter 2 and a clamping assembly mounted on the frame 1. The clamping assembly includes a first clamping seat 3, a first clamping plate 4, and a second clamping plate 5. The first clamping seat 3 is fixedly connected to the output end of a first horizontal drive mechanism 7. Under the driving action of the first horizontal drive mechanism 7, the first clamping seat 3 can move in a direction parallel to the rotation axis 603 of the saw blade 201 in the cutter 2. In the horizontal direction perpendicular to the movement of the first clamping seat 3, the first clamping plate 4 is vertically fixed on the first clamping seat 3 at one end near the cutter 2. The second clamping plate 5 is arranged opposite to the first clamping plate 4 and is fixedly connected to the output end of a second horizontal drive mechanism 17, so that the second clamping plate 5 can move closer to or away from the first clamping plate 4. There is a first clamping area between the first clamping plate 4 and the second clamping plate 5 for clamping the profile 8. When the second clamping plate 5 moves closer to the first clamping plate 4, it can clamp the profile 8; otherwise, it can release the profile 8. The second clamping plate 5 is also provided with a profile detection component 6 for determining whether there is a profile 8 in the clamping area; the cutting mechanism also includes a displacement monitoring mechanism (not shown in the figure), which is used to monitor the displacement of the first clamping seat 3.

[0024] During processing, the feeding mechanism of the unloading machine sends the profile 8 to the first clamping area of ​​the clamping component in the cutting mechanism. The second horizontal drive mechanism 17 pushes out the second clamping plate 5, which, together with the first clamping plate 4, clamps the profile 8. Then, the first horizontal drive mechanism 7 pushes the first clamping seat 3 and the profile 8 toward the cutting machine 2. When the profile 8 reaches the cutting position, the cutting machine 2 cuts the profile 8 to obtain a desired product. The second clamping plate 5 releases the profile 8, and the first clamping seat 3 retreats a set distance under the action of the first horizontal drive mechanism 7. This set distance is usually the thickness of the saw blade 201 + the length of the desired product + the error compensation distance. The second clamping plate 5 re-clamps the profile 8 and again moves forward (in this embodiment, "forward" refers to the direction closer to the cutting machine 2) the above-mentioned set distance for cutting. This process is repeated to obtain multiple desired products. When the first clamping seat 3 retracts a set distance, during the clamping process of the second clamping plate 5, if the profile detection component 6 detects that there is no profile 8 in the first clamping area, the first clamping seat 3 moves forward under the action of the second horizontal drive mechanism 17 until the profile detection component 6 touches the profile 8 and detects the profile 8. At this time, the displacement monitoring mechanism can determine the remaining length of the profile 8 based on the moving distance of the second clamping plate 5. If the remaining length of the profile 8 is sufficient for one cut, the second clamping plate 5 re-clamps the profile 8 and uses the first horizontal drive mechanism 7 to drive the profile 8 forward for cutting. If the remaining length of the profile 8 is insufficient for one cut, the material is reloaded. When the first horizontal drive mechanism 7 is conveying the next profile 8, it pushes out the remaining part of the previous profile 8.

[0025] Since the cutting machine 2 remains stationary in the extension and retraction direction of the first horizontal drive mechanism 7 in this embodiment, and parameters such as the thickness of the saw blade 201 and the position of the cutting machine 2 are known, the length of the remaining profile 8 between the first clamping seat 3 and the saw blade 201 can be obtained by monitoring the position and moving distance of the first clamping seat 3. The displacement monitoring mechanism can be a position sensor or other displacement monitoring mechanism installed on the first clamping seat 3. The technology for monitoring the position of a certain mechanism is well known to those skilled in the art; therefore, its detailed structure and working principle will not be described in detail in this embodiment.

[0026] Therefore, by setting the profile detection component 6 on the second clamping plate 5, this embodiment can detect whether there is a profile 8 in the first clamping area, and combined with the displacement monitoring mechanism, it can detect the length of the remaining profile 8, thereby determining whether the remaining profile 8 can be cut again for subsequent instructions. This not only improves the accuracy of judging the length of the remaining profile 8, but also allows the remaining profile 8 to be pushed out by the first horizontal drive mechanism 7 conveying the next profile 8, without the need for other mechanisms or manual removal of the remaining profile 8, which is beneficial to improving the continuity of the processing process and production efficiency.

[0027] In this embodiment, the profile detection component 6 includes a rotating rod 601 and an abutment post 602. The rotating rod 601 is rotatably mounted on the top of the second clamping plate 5 via a vertically arranged rotating shaft 603. The end of the rotating rod 601 near the cutting machine 2 is vertically connected to the abutment post 602. The rotating shaft 603 is connected to an elastic element, which is used to resist the rotation of the rotating shaft 603. Specifically, the elastic element can be a torsion spring disposed inside the second clamping plate 5. If there is no profile 8 in the first clamping area, the abutment post 602 extends into the first clamping area under the action of the elastic element (the deflection angle of the rotating rod 601 is 5°~10° relative to the state in which there is a profile 8 in the first clamping area). Figure 5 As shown; if profile 8 is present in the first clamping area, profile 8 will press against the abutment post 602 extending into the first clamping area, so that the end face of the second clamping plate 5 and the side wall of the abutment post 602 are tightly against the wall of profile 8, such as Figure 4 As shown. Those skilled in the art should also understand that this embodiment also includes monitoring elements for monitoring the position of the rotating rod 601 or whether the side wall of the abutment post 602 is in contact with the profile 8. The element for monitoring the position of the rotating rod 601 can be a position sensor, and the element for monitoring whether there is a contact object on the side wall of the abutment post 602 can be a piezoelectric sensor. The principle of determining whether there is a profile 8 in the first clamping area based on the rotation state of the rotating rod 601 is something that those skilled in the art can achieve based on their own skills and existing technology, and this embodiment will not elaborate on this.

[0028] In this embodiment, multiple bearings 604 are rotatably mounted on the abutment post 602 from top to bottom. The bearings 604 are used to abut against the profile 8.

[0029] like Figure 2 , Figure 3 As shown, this embodiment also includes a support plate 9 and a second clamping seat 10 disposed on the frame 1. Both the support plate 9 and the second clamping seat 10 are located on the radial side of the upper saw blade 201 of the cutting machine 2. The second clamping seat 10 is provided with a lifting drive mechanism 11 and a lower pressure plate 12 fixed to the lifting end of the lifting drive mechanism 11. The lower pressure plate 12 is located above the support plate 9 and is used to press the profile 8 onto the support plate 9.

[0030] In this embodiment, a third clamping plate 13 is vertically arranged on the support plate 9 near the saw blade 201. The frame 1 is also provided with a third horizontal drive mechanism and a fourth clamping plate 14 disposed at the moving end of the third horizontal drive mechanism. The fourth clamping plate 14 is directly opposite the third clamping plate 13, and a second clamping area is formed between the fourth clamping plate 14 and the third clamping plate 13. The third clamping plate 13 and the lower pressure plate 12 are used to clamp the profile 8 in the second clamping area to prevent the profile 8 from moving when the saw blade 201 cuts the profile 8.

[0031] In this embodiment, the third clamping plate 13 is provided with a slit 1301 for the saw blade 201 to pass through.

[0032] In this embodiment, the base of the cutting machine 2 is fixedly connected to the output end of the fourth horizontal drive mechanism (not shown in the figure). The fourth horizontal drive mechanism is used to drive the cutting machine 2 to move closer to or away from the second clamping area in order to cut the profile 8.

[0033] In this embodiment, the first horizontal drive mechanism 7 is a ball screw mechanism, and the first clamping seat 3 is fixedly connected to the balls in the ball screw mechanism. The ball screw mechanism has a fast adjustment speed and high adjustment accuracy, which is beneficial for precise adjustment and detection of the position of the first clamping seat 3. The second horizontal drive mechanism 17, the third horizontal drive mechanism, the fourth horizontal drive mechanism, and the lifting drive mechanism 11 are hydraulic cylinders or pneumatic cylinders, which use the extension and retraction of the hydraulic cylinders or pneumatic cylinders to drive the corresponding components to move.

[0034] In this embodiment, the frame 1 is also equipped with a head end detector 15 for detecting the position of the head end of the profile 8. The head end detector 15 can be a laser sensor. When the first clamping seat 3 moves forward to feed the material, the laser sensor will issue a command after the front end of the profile 8 reaches the center position of the laser sensor. Based on the current position of the profile 8 and the position of the saw blade 201, the required forward feeding distance can be calculated to meet the cutting requirements of the desired product, thereby achieving precise positioning.

[0035] Example 2: This embodiment provides a cutting method for a blanking machine. Based on the cutting mechanism in Embodiment 1, the cutting method includes the following steps: The feeding mechanism 16 of the unloading machine transports the profile 8 to the first clamping area, and the second horizontal drive mechanism 17 pushes out the second clamping plate 5. The first clamping plate 4 and the second clamping plate 5 clamp the profile 8. The first horizontal drive mechanism 7 pushes the first clamping seat 3 and the profile 8 toward the cutting machine 2. After the head end detector 15 detects the head end of the profile 8, it records the current position of the head end of the profile 8. The first horizontal drive mechanism 7 continues to work and conveys the profile 8 forward. When the profile 8 reaches the cutting position, the third horizontal drive mechanism pushes the fourth clamping plate 14 to extend and clamp the profile 8 horizontally. The lifting drive mechanism 11 works and the lower pressure plate 12 descends to vertically press the profile 8. The fourth horizontal drive mechanism operates, pushing the cutting machine 2 to move and cut the profile 8; after cutting is completed, the cutting machine 2 retracts. The second clamping plate 5 loosens the profile 8, the first clamping seat 3 retracts a set distance, re-clamps the profile 8, and then feeds the profile 8 forward again for cutting. Repeat this process; When the first clamping seat 3 retracts a set distance, during the clamping process of the second clamping plate 5, the profile detection component 6 detects that there is no profile 8 in the first clamping area. Then, the first clamping seat 3 moves forward under the action of the second horizontal drive mechanism 17 until the profile detection component 6 touches the end of the profile 8, that is, the position of the profile 8 is detected. At this time, the displacement monitoring mechanism judges the remaining length of the profile 8 based on the moving distance of the second clamping plate 5. If the remaining length of the profile 8 is sufficient for one cut, the second clamping plate 5 re-clamps the profile 8 and uses the first horizontal drive mechanism 7 to drive the profile 8 forward for cutting. If the remaining length of the profile 8 is insufficient for one cut, the material is reloaded. When the first horizontal drive mechanism 7 is conveying the next profile 8, it pushes out the remaining part of the previous profile 8.

[0036] Any adaptive changes made according to actual needs are within the protection scope of this utility model.

[0037] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
