Description

Technical Field

[0001] The present invention relates to the technical field of metal processing, and particularly relates to a metal cutting device that is convenient to adjust. Background Art

[0002] In modern industrial production, metal cutting is an extremely important link, widely used in many fields such as machinery manufacturing, construction, automobiles, aerospace, etc. With the continuous progress of technology and the increasingly diverse demands of industrial production, higher requirements are put forward for the performance and functions of metal cutting devices.

[0003] During the metal cutting process, accurate positioning is crucial for ensuring cutting quality and product precision. Generally speaking, in the metal processing process, the cutting process is just one link in the processing process. For example, a long strip of metal plate is cut into small metal pieces, and then the small metal pieces are further processed through subsequent processing techniques such as stamping, bending, drilling, and other processes to complete the processing of metal parts.

[0004] The existing metal cutting devices have a relatively simple structure, insufficiently rich functions, and limited ability to adjust parameters such as cutting length and spacing. When performing metal cutting of different sizes and specifications, it is often necessary to perform complex adjustments to the device or replace the fixture, which is cumbersome to operate and difficult to achieve fast and accurate adjustment. Some devices can only perform ordinary cutting and cannot meet special processing requirements such as equidistant cutting, and cannot adapt to diverse production needs. Summary of the Invention

[0005] The purpose of the present invention is to provide a metal cutting device that is convenient to adjust, and solve the problems that the existing metal cutting devices have a relatively simple structure, insufficiently rich functions, limited ability to adjust parameters such as cutting length and spacing, and often need to perform complex adjustments to the device or replace the fixture, which is cumbersome to operate.

[0006] To solve the above technical problems, the present invention adopts the following technical solutions: A metal cutting device that is convenient to adjust, including a device body. There is a processing platform arranged on the upper side of the device body. There is a cutting hole penetrating through the upper and lower sides arranged on the upper side of the processing platform. A cutting blade is arranged to move up and down above the cutting hole. One side of the edge of the processing platform perpendicular to the cutting blade is set as a feed inlet. There is a feed fixing plate arranged to move up and down at the position of the feed inlet of the processing platform. There is an end fixing plate arranged on the side of the cutting hole away from the feed inlet of the cutting blade. A clamping assembly is arranged on the side of the end fixing plate facing the cutting blade. There is a driving assembly arranged on the lower side of the processing platform for controlling the front and back adjustment of the end fixing plate along the direction perpendicular to the cutting blade.

[0007] A further technical solution is that the driving component includes a driving block, a driving rod, and a push rod motor. The driving block is installed on the lower side of the processing platform on the side of the end fixing plate away from the cutting blade. A first guiding hole penetrating both sides is provided on the driving block, and the axial direction of the first guiding hole is perpendicular to the end fixing plate. The driving rod is slidably arranged in the first guiding hole. One end of the driving rod is connected to the end fixing plate, and the other end is coaxially connected to the push rod motor.

[0008] A further technical solution is that a guiding block is also provided on the lower side of the processing platform. A second guiding hole with the same hole direction as the first guiding hole is provided on the guiding block. A guiding rod is slidably arranged in the second guiding hole, and one end of the guiding rod is connected to the end fixing plate.

[0009] A further technical solution is that a fixed strip and a movable strip are horizontally arranged on the side of the end fixing plate facing the cutting blade. An adjusting strip hole penetrating both sides is vertically arranged on the side of the end fixing plate facing the cutting blade. A slider is slidably arranged up and down in the adjusting strip hole, and one end of the slider is connected to the movable strip. A first cylinder is vertically arranged on the side of the end fixing plate away from the movable strip, and the output shaft of the first cylinder is connected to the slider; the movable strip is arranged above the fixed strip, and the upper side of the fixed strip is flush with the upper side of the processing platform.

[0010] A further technical solution is that a second cylinder is vertically arranged above the feeding fixing plate. The output shaft of the second cylinder faces downward and is connected to the upper side of the feeding fixing plate. A first rubber layer is arranged on the lower side of the feeding fixing plate, and a second rubber layer is arranged on the lower side of the movable strip.

[0011] A further technical solution is that a distance sensor is arranged above the feeding port and is aligned with the feeding port.

[0012] A further technical solution is that an installation hole penetrating the upper and lower sides is provided on the processing platform on the side of the cutting hole away from the feeding port. A mounting plate is movably arranged in the installation hole. One end of the mounting plate is rotatably connected to the hole wall of the installation hole through a horizontally arranged rotating shaft. A third cylinder is arranged on the lower side of the processing platform, and the output shaft of the third cylinder is connected to the lower side of the mounting plate. A motor is installed on the upper side of the mounting plate, and the output shaft of the motor is drivingly connected to the cutting blade.

A strip hole penetrating the upper and lower sides is arranged on the upper side of the processing platform along the direction from the guiding plate to the movable guiding plate. The through hole and the strip hole are fixed by adjusting bolts.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When cutting, the strip-shaped metal plate to be cut moves from the position of the feed port to the position of the cutting hole and abuts against the feed fixing plate. In this way, when the cutting blade moves down, the part between the cutting blade and the feed fixing plate can be cut off to obtain a metal workpiece with a fixed size, which is convenient for subsequent processing; 2. By setting the driving component, the position of the feed fixing plate can be adjusted, so as to control the distance between the feed fixing plate and the cutting blade, and thus the size of the cut metal workpiece can be quickly adjusted; 3. By setting the feed fixing plate, the uncut part of the strip-shaped metal plate can be fixed; 4. By setting the clamping component, the metal workpiece to be cut off can be fixed. In this way, when the metal workpiece is about to fall off during cutting, the metal workpiece can still be kept flush with the strip-shaped metal plate, which is beneficial to improving the smoothness of the cut.

Detailed implementation mode

[0026] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0027] Figures 1 to 9 The following shows an embodiment of the present invention.

[0028] Embodiment 1: A metal cutting device that is easy to adjust, including a device body 1. A processing platform 2 is provided on the upper side of the device body 1. A cutting hole 3 that penetrates the upper and lower sides is provided on the upper side of the processing platform 2. A cutting blade 4 is movably arranged up and down above the cutting hole 3. One side of the edge of the processing platform 2 perpendicular to the cutting blade 4 is set as a feeding port 5. A feeding fixed plate 6 is movably arranged up and down at the position of the feeding port 5 on the processing platform 2. An end fixed plate 7 is provided on the side of the cutting hole 3 away from the feeding port 5 of the cutting blade 4. A clamping assembly is provided on the side of the end fixed plate 7 facing the cutting blade 4. A driving assembly for controlling the front and back adjustment of the end fixed plate 7 along the direction perpendicular to the cutting blade 4 is provided on the lower side of the processing platform 2. When cutting, the strip-shaped metal plate to be cut moves from the position of the feeding port 5 to the position of the cutting hole 3 and abuts against the feeding fixed plate 6. In this way, when the cutting blade 4 moves down, the part between the cutting blade 4 and the feeding fixed plate 6 can be cut off to obtain a metal workpiece with a fixed size, which is convenient for subsequent processing. By setting the driving assembly, the position of the feeding fixed plate 6 can be adjusted, so as to control the distance between the feeding fixed plate 6 and the cutting blade 4, and thus the size of the cut metal workpiece can be quickly adjusted. By setting the feeding fixed plate 6, the uncut part of the strip-shaped metal plate can be fixed. By setting the clamping assembly, the metal workpiece to be cut can be fixed. In this way, when the metal workpiece is about to fall off during cutting, the metal workpiece can still be kept flush with the strip-shaped metal plate, which is beneficial to improving the smoothness of the cut.

[0029] The driving assembly includes a driving block 8, a driving rod 9, and a push rod motor 2610. The driving block 8 is installed on the lower side of the processing platform 2 on the side of the end fixing plate 7 away from the cutting blade 4. A first guiding hole 11 penetrating both sides is provided on the driving block 8. The axial direction of the first guiding hole 11 is perpendicular to the end fixing plate 7. The driving rod 9 is slidably arranged in the first guiding hole 11. One end of the driving rod 9 is connected to the end fixing plate 7, and the other end is coaxially connected to the push rod motor 2610. With such a setting, when it is necessary to adjust the distance between the end fixing plate 7 and the cutting blade 4, the pneumatic push rod motor 2610 is used to drive the driving rod 9 to perform a linear motion in the first guiding hole 11, thereby driving the end fixing plate 7 to move, so as to control the distance between the end fixing plate 7 and the cutting blade 4.

[0030] A guiding block 13 is further provided on the lower side of the processing platform 2. A second guiding hole with the same hole direction as the first guiding hole 11 is provided on the guiding block 13. A guiding rod 14 is slidably arranged in the second guiding hole. One end of the guiding rod 14 is connected to the end fixing plate 7. By providing the guiding block 13 and the guiding rod 14, the guiding rod 14 can be used to slide along the second guiding hole to play an auxiliary guiding role for the end fixing plate 7, so as to cooperate with the driving rod 9 to make the end fixing plate 7 move more stably and smoothly when moving, and avoid the end fixing plate 7 tilting after moving, which affects the processing accuracy.

[0031] A fixing strip 15 and a movable strip 16 are horizontally arranged on the side of the end fixing plate 7 facing the cutting blade 4. An adjusting strip hole 3117 penetrating both sides is vertically provided on the side of the end fixing plate 7 facing the cutting blade 4. A slider 18 is slidably arranged up and down in the adjusting strip hole 3117. One end of the slider 18 is connected to the movable strip 16. A first cylinder 19 is vertically arranged on the side of the end fixing plate 7 away from the movable strip 16. The output shaft of the first cylinder 19 is connected to the slider 18; the movable strip 16 is arranged above the fixing strip 15, and the upper side of the fixing strip 15 is flush with the upper side of the processing platform 2. Before the end of the strip-shaped metal plate abuts against the end fixing plate 7, the movable strip 16 moves upward under the drive of the first cylinder 19, and the distance between the movable strip 16 and the fixing strip 15 is greater than the thickness of the strip-shaped metal plate. When the end of the strip-shaped metal plate abuts against the end fixing plate 7, the lower side of the end of the strip-shaped metal plate fits with the upper side of the fixing strip 15. At this time, the movable strip 16 moves downward under the drive of the first cylinder 19 and fits with the upper and lower sides of the end of the strip-shaped metal plate. In this way, the end of the strip-shaped metal plate is fixed. During cutting, the cut part can be kept stable. After cutting, only by moving the movable strip 16 upward can the cut metal workpiece be released, and the metal workpiece will fall naturally. By setting the slider 18 and the adjusting strip hole 3117 in cooperation, the movable strip can move up and down smoothly and keep the movable strip 16 in a horizontal state. At least two or more adjusting strip holes 3117 and sliders 18 are provided.

[0032] A second cylinder 20 is vertically arranged above the feed fixing plate 6. The output shaft of the second cylinder 20 faces downward and is connected to the upper side of the feed fixing plate 6. A first rubber layer 21 is arranged on the lower side of the feed fixing plate 6, and a second rubber layer is arranged on the lower side of the movable strip 16.

[0033] A distance sensor 22 is arranged above the feed inlet 5 and is aligned with the feed inlet 5. By arranging the distance sensor 22, the distance from the distance sensor 22 to the strip-shaped metal plate can be measured to calculate the thickness of the strip-shaped metal plate. In this way, when the feed fixing plate 6 moves downward to press the strip-shaped metal plate, the distance of the downward movement of the feed fixing plate 6 can be controlled by the second cylinder 20, avoiding excessive downward movement and causing too much burden on the second cylinder 20, and avoiding applying too much pressure to some strip-shaped metal plates with special shapes and causing deformation. Cooperating with the first rubber layer 21, it can serve as a buffer layer to play the role of pressing and fixing and protecting the strip-shaped metal plate. Similarly, the distance sensor 22 can be used to control the distance of the up and down movement of the movable strip 16 driven by the first cylinder 19, and the second rubber layer can be used to play the role of pressing and fixing and protecting the strip-shaped metal plate.

[0034] On the side of the processing platform 2 where the cutting hole 3 is far from the feed inlet 5, an installation hole 23 penetrating through the upper and lower sides is arranged. An installation plate 24 is movably arranged in the installation hole 23. One end of the installation plate 24 is rotationally connected to the hole wall of the installation hole 23 through a horizontally arranged rotating shaft. A third cylinder 25 is arranged on the lower side of the processing platform 2. The output shaft of the third cylinder 25 is connected to the lower side of the installation plate 24. A motor 26 is installed on the upper side of the installation plate 24, and the output shaft of the motor 26 is in transmission connection with the cutting blade 4. Through the cooperation of the third cylinder 25 and the installation plate 24, the motor 26 can be driven to swing up and down around the rotating shaft, thereby driving the cutting blade 4 to move up and down. When the cutting blade 4 moves up, the strip-shaped metal plate can be abutted against the end fixing plate 7, and then the installation plate 24 swings downward to complete the cutting of the strip-shaped metal plate.

[0035] The device body 1 is provided with a collection cart 27 on the lower side of the processing platform 2. The upper side of the collection cart 27 is provided with an opening, and the opening is aligned with the cutting hole 3. By arranging the collection cart 27, the cut metal workpiece can directly fall into the collection cart 27, which is convenient for transporting to the next process for processing.

[0036] On the upper side of the processing platform 2, a fixed guide plate 28 and a movable guide plate 29 are arranged at intervals at the position of the feeding port 5. On the side of the movable guide plate 29 away from the fixed guide plate 28, an adjusting fixed plate 30 is arranged. Through holes penetrating the upper and lower sides are arranged on the guide fixed plate. On the upper side of the processing platform 2, a slot 31 penetrating the upper and lower sides is arranged along the direction from the guide plate to the movable guide plate 29. The through hole and the slot 31 are fixed by an adjusting bolt 32. Through the cooperation of the fixed guide plate 28 and the movable guide plate 29, when conveying the strip-shaped metal plate, the strip-shaped metal plate can be guided to avoid tilting during the conveying process. With the cooperation of the slot 31, the adjusting fixed plate 30 and the adjusting bolt 32, the distance between the movable guide plate 29 and the fixed guide plate 28 can be controlled, so as to be applicable to strip-shaped metal plates of different widths. In order to improve the smoothness of conveying, rolling shafts can be arranged on the opposite sides of the fixed guide plate 28 and the movable guide plate 29 to reduce the friction with the strip-shaped metal plate.

[0037] Although the present invention has been described herein with reference to various illustrative embodiments of the invention, it should be understood that those skilled in the art can devise many other modifications and embodiments that will fall within the scope of the principles of this application and the spirit thereof. More particularly, within the scope of this application's disclosure, the drawings, and the claims, various variations and improvements can be made to the components and / or the layout of the subject combination layout. In addition to the variations and improvements made to the components and / or the layout, other uses will also be apparent to those skilled in the art.
