Description

Technical Field

[0001] This utility model relates to the field of alloy sheet production technology, specifically to an alloy sheet stretching and forming device. Background Technology

[0002] Alloy plates refer to metal plates made from two or more metallic elements through processes such as smelting, casting, and rolling. Alloy plate stretching and forming equipment is a type of mechanical equipment specifically used to process metal alloy plates into parts of specific shapes and sizes through stretching processes.

[0003] A search revealed CN219805210U, which discloses a stretching device for heat-treated aluminum alloy sheets. This device involves setting a limiting block at the lower end of a boss and sliding it inside a slide rail. A rotating bidirectional transmission screw, through its internal helical structure, moves the limiting block inward to form a clamp, with a rubber convex pad providing anti-slip protection. However, this device still relies on manual operation for loading the alloy sheet. As working time increases, the operator's physical strength gradually decreases, leading to a slowdown in loading speed and ultimately reducing the stretching efficiency of the alloy sheet. Therefore, we propose a stretching and forming device for alloy sheets. Utility Model Content

[0004] The purpose of this invention is to provide an alloy sheet stretching and forming device.

[0005] To address the problems mentioned in the background art, this utility model provides the following technical solution: an alloy sheet stretching and forming device, comprising a base, a control box fixed to one end of the base, fixed columns fixed to the four corners of the upper end of the base, a top plate fixed to the upper end of each fixed column, a lifting plate slidably mounted on the upper side of each fixed column, stretching cylinders provided on both sides of the lifting plate, a punch mounted on the lower end of the lifting plate, first connecting blocks fixed to the four corners of the upper end of the punch, second connecting blocks fixed to both ends of the upper end of the lifting plate, and a concave die fixed to the center of the upper end of the base. Bolts are provided on one side of the first connecting block and the upper end of the die. A mounting seat is fixed to the other end of the base. A conveyor belt is provided on the inner side of the mounting seat. Multiple sets of transmission columns are installed on the inner side of the conveyor belt. A first motor is provided at one end of one of the transmission columns. An electric push rod is fixed at one end of the mounting seat near the other side. A push plate is installed at one end of the electric push rod. First slide rods are fixed on both sides of one end of the push plate. A second slide rod and a first spiral column are respectively provided on one side of the upper end of the mounting seat. A limiting plate is installed on one side inside the mounting seat. Multiple sets of limiting plates are fixed to one end of the conveyor belt.

[0006] Preferably, there are four transmission columns, each of which passes through the mounting base and is rotatably connected to the mounting base.

[0007] Preferably, the mounting base is slidably connected to the push plate, the first slide rod passes through the mounting base, and the first slide rod is slidably connected to the mounting base.

[0008] Preferably, both the second slide bar and the first spiral column pass through the limiting plate, and the second slide bar is slidably connected to the limiting plate.

[0009] Preferably, a rotating groove is provided on one side of the top inside the base, and a second spiral column is rotatably arranged inside the rotating groove. Multiple sets of sliding columns are fixed on one side of the bottom inside the base, and a second motor is provided on the other side of the bottom inside the base. A sliding plate is slidably installed on one side of the inside of the base, and a top block is fixed at the center of the upper end of the sliding plate.

[0010] Preferably, there are two sliding pillars, and the sliding pillars are located at both ends of the bottom inside the base.

[0011] Preferably, both the sliding column and the second spiral column pass through the sliding plate, and the sliding column is slidably connected to the sliding plate.

[0012] Using the above technical solution, the alloy sheet is placed on the conveyor belt, and then the first motor is started. The first motor drives the conveyor belt to rotate through the transmission column, and the conveyor belt pushes the alloy sheet to move through the limiting plate. When the alloy sheet is in contact with one end of the push plate, it stops. Then, the electric push rod is started, and the electric push rod pushes the alloy sheet to slide out from the bottom of the limiting plate through the push plate. When the alloy sheet is in contact with the die, it stops. At this time, the push plate and the die limit the alloy sheet around its perimeter. Then, the stretching cylinder is started, and the punch stretches and forms the alloy sheet. By rotating the first spiral column in the forward direction, the first spiral column drives the limiting plate to rise, increasing the distance between the limiting plate and the conveyor belt. Conversely, it lowers the limiting plate to accommodate alloy sheets of different thicknesses. This allows the alloy sheet stretching and forming device to quickly feed alloy sheets of different thicknesses, thereby improving the working efficiency of the alloy sheet stretching and forming device.

[0013] Using the above technical solution, after the alloy sheet is stretched and formed, the second motor is started in the forward direction. The second motor drives the slide plate to slide upward inside the base through the second helical column. At the same time, the slide plate slides on the sliding column, making the lifting and lowering of the slide plate more stable. Then, when the slide plate rises, it slides through the top block in the base and the die, thereby lifting the stretched alloy sheet and separating it from the die. Then, the stretched alloy sheet is taken out. Then, the second motor is started in the reverse direction, and the second motor drives the slide plate to pull the top block down through the second helical column, so that the top block returns to its original position. This allows the alloy sheet stretching and forming device to lift the formed alloy sheet after stretching and forming, so that the alloy sheet separates from the die and facilitates the subsequent removal of the alloy sheet.

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] Example 1:

[0021] Please see Figure 1-4This utility model provides a technical solution: an alloy sheet stretching and forming device, including a base 1, a control box 2 fixed to one end of the base 1, four fixed columns 3 fixed to the upper end of the base 1, a top plate 4 fixed to the upper end of the fixed columns 3, a lifting plate 5 slidably installed near the upper side of the fixed columns 3, stretching cylinders 6 provided on both sides of the lifting plate 5, a punch 7 installed at the lower end of the lifting plate 5, first connecting blocks 8 fixed to the four corners of the upper end of the punch 7, second connecting blocks 9 fixed to both ends of the upper end of the lifting plate 5, a concave die 10 fixed to the center of the upper end of the base 1, bolts 11 provided on one side of the first connecting block 8 and the upper end of the concave die 10, a mounting base 12 fixed to the other end of the base 1, a conveyor belt 13 provided inside the mounting base 12, multiple sets of transmission columns 14 installed inside the conveyor belt 13, and one side of the transmission column 14... A first motor 15 is provided at one end. An electric push rod 17 is fixed at one end of the mounting base 12 near the other side. A push plate 19 is installed at one end of the electric push rod 17. A first slide rod 18 is fixed on both sides of one end of the push plate 19. A second slide rod 21 and a first spiral column 22 are respectively provided on one side of the upper end of the mounting base 12. A limiting plate 20 is installed on one side inside the mounting base 12. Multiple sets of limiting plates 16 are fixed at one end of the conveyor belt 13. There are four transmission columns 14. The transmission columns 14 pass through the mounting base 12 and are rotatably connected to the mounting base 12. The mounting base 12 is slidably connected to the push plate 19. The first slide rod 18 passes through the mounting base 12 and is slidably connected to the mounting base 12. The second slide rod 21 and the first spiral column 22 both pass through the limiting plate 20 and are slidably connected to the limiting plate 20.

[0022] Specifically, the alloy sheet is placed on the conveyor belt 13 and positioned between the two limiting plates 16. Then, the first motor 15 is started via the control box 2, causing the first motor 15 to drive the conveyor belt 13 to rotate via the transmission column 14. At this time, the conveyor belt 13 will move the alloy sheet to one side. When the alloy sheet is in contact with one end of the push plate 19, it stops. Then, the electric push rod 17 is started via the control box 2, causing the electric push rod 17 to push the push plate 19 to one side. At the same time, when the push plate 19 moves, it will pull the first slide rod 18 to slide in the mounting base 12. Then, the push plate 19 will push the alloy sheet through the bottom of the limiting plate 20 and move towards the die 10. When the alloy sheet is in contact with the inner side of the die 10, it stops. At this time, the push plate 19 and the die 10 will limit the alloy sheet around its perimeter. Then, by starting the stretching cylinder 6 in the forward direction through the control box 2, the stretching cylinder 6 stretches the lifting plate 5, causing the lifting plate 5 to slide on the fixed column 3 and push the punch 7 to stretch and form the alloy sheet. Then, by starting the electric push rod 17 in the reverse direction through the control box 2, the electric push rod 17 drives the push plate 19 back to its original position. When it is necessary to adjust the distance between the limiting plate 20 and the conveyor belt 13, the first spiral column 22 is rotated in the forward direction, causing the first spiral column 22 to drive the limiting plate 20 to rise. At the same time, the limiting plate 20 will slide in the second slide rod 21, increasing the distance between the limiting plate 20 and the conveyor belt 13 to the required position and then stopping. Conversely, it descends to accommodate alloy sheets of different thicknesses, so that the alloy sheet stretching and forming device can quickly feed alloy sheets of different thicknesses, thereby improving the working efficiency of the alloy sheet stretching and forming device.

[0023] Example 2:

[0024] Please see Figure 1-4 This utility model provides a technical solution: an alloy sheet stretching and forming device, wherein a rotating groove 25 is provided on one side of the top inside the base 1, a second spiral column 24 is rotatably arranged inside the rotating groove 25, multiple sets of sliding columns 28 are fixed on one side of the bottom inside the base 1, a second motor 23 is arranged on the other side of the bottom inside the base 1, a sliding plate 26 is slidably installed on one side of the bottom inside the base 1, and a top block 27 is fixed at the center of the upper end of the sliding plate 26; there are two sliding columns 28, and the sliding columns 28 are respectively located at both ends of the bottom inside the base 1; both the sliding column 28 and the second spiral column 24 pass through the sliding plate 26, and the sliding column 28 and the sliding plate 26 are slidably connected.

[0025] Specifically, after the alloy sheet is stretched and formed inside the die 10, the second motor 23 is started by the control box 2, which drives the second spiral column 24 to rotate inside the rotating groove 25. The second spiral column 24 then drives the slide plate 26 to slide on the slide column 28. When the second spiral column 24 rises, it pushes the top block 27 to rise as well, causing the top block 27 to slide between the base 1 and the die 10, thereby lifting the stretched alloy sheet. At this time, the stretched alloy sheet will separate from the die 10. Then, the stretched alloy sheet is taken out. Then, the second motor 23 is started in reverse, which drives the slide plate 26 to pull the top block 27 down through the second spiral column 24, so that the top block 27 returns to its original position. This allows the alloy sheet stretching and forming device to lift the formed alloy sheet after stretching and forming, so that the alloy sheet separates from the die 10, facilitating the subsequent removal of the alloy sheet.
