A forming equipment for aluminum profiles

Abstract

This invention relates to the field of aluminum profile processing and discloses a forming device for aluminum profiles, including a frame, side wing plates, and a bending die. The top of the frame is fitted with a side wing plate, and a rotating shaft passes between two side wing plates. The bending die is fitted onto the rotating shaft. A protective structure is installed on the frame, and an automatic bending structure is provided on the frame. When a first hydraulic cylinder is activated, the aluminum profile is moved upwards. When one end of the support plate is pressed against the lower inner wall of the opening, the compression of a first spring allows the lifting plate to continue moving upwards. The sliding of the driving rod in the first guide groove and the sliding of the insertion rod in the second guide groove cause the clamping blocks to move horizontally while simultaneously moving towards each other. This clamping action onto the aluminum profile allows the aluminum profile to be automatically pushed below the bending die for automatic bending, making the operation more labor-saving, convenient, and improving work efficiency.

Description

Technical Field

[0001] This invention relates to the field of aluminum profile processing, and in particular to a forming device for aluminum profiles. Background Technology

[0002] Aluminum profiles are increasingly used in daily life due to their many advantages, such as low density, light weight, strong corrosion resistance, good processing performance, good radiation resistance, low elastic modulus, no sparks generated upon impact, and good thermal and electrical conductivity. When forming aluminum profiles, forming equipment is required to perform bending and forming work. The current forming equipment places the aluminum profile in the groove of the pallet, then starts the power unit to raise the aluminum profile to fit with the bending groove of the bending die. The clamping mechanism is used to clamp the positioned aluminum profile at one end of the bending die. Then, the slider is moved on the carriage, and the first through hole of the slider passes through the aluminum profile. Finally, the drive mechanism is started to drive the rotating block to rotate. Since one end of the aluminum profile is fixed on the bending die and supported by the pallet below, it will bend along the bending groove on the bending die to perform the bending forming work. However, in the actual processing, the aluminum profile after it has been moved up needs to be pushed manually to the bottom of the bending die, and the sliding block on the carriage needs to be put onto the aluminum profile before the bending work can be carried out. This operation is time-consuming and labor-intensive, reducing work efficiency. Summary of the Invention

[0013] In summary, the present invention has the following beneficial technical effects: 1. This invention comprises a frame with side wing plates, a rotating shaft, a bending die, an opening, a fixed plate, a first hydraulic cylinder, a support plate, a horizontal plate, a lifting plate, a first fixed rod, a first spring, a first sleeve, a driving rod, a vertical plate, a first guide groove, a U-shaped strip, a second fixed rod, a second spring, a second sleeve, an insert rod, a second guide groove, and clamping blocks. The aluminum profile to be bent is placed on the support plate. The first hydraulic cylinder is activated to move the aluminum profile upwards. When one end of the support plate is pressed against the lower inner wall of the opening, the compression of the first spring allows the lifting plate to continue moving upwards. The sliding of the driving rod in the first guide groove and the sliding of the insert rod in the second guide groove cause the clamping blocks to move horizontally while simultaneously moving towards each other. By clamping the aluminum profile with the clamping blocks, the aluminum profile can be automatically pushed to the bottom of the bending die for automatic bending. This operation is more labor-saving and convenient, improving work efficiency. 2. This invention features a groove, adjusting strip, stop block, first guide rod, fourth spring, screw, turntable, and limiting block on a pallet. Under the elastic force of the fourth spring, the stop block can be pushed out of the groove, limiting the position of the aluminum profile on the pallet. When the clamping block moves the aluminum profile a fixed distance, the position to be bent on the aluminum profile can be moved to the bending die for bending, improving the bending quality. Furthermore, the rotation of the screw drives the rotation of the plate, allowing the position of the stop block to be adjusted according to the position to be bent on the aluminum profile. Simultaneously, when the pallet moves the aluminum profile to the horizontal plate, the pressure of the horizontal plate on the stop block pushes the stop block into the groove, releasing the limiting on the aluminum profile on the pallet. This allows the clamping block to smoothly clamp the aluminum profile and move it to the bending die for processing. The invention has a simple structure and strong functionality. 3. This invention features a high-pressure gas source, a gas delivery pipe, and a gas delivery head on the frame, and an L-shaped rod, an end block, a sleeve block, a third spring, and a movable sleeve on the bending die. The gas delivery head is installed in the movable sleeve. When the aluminum profile is sent to the bottom of the bending die, one end of the aluminum profile can be automatically inserted into the gas delivery head. The high-pressure source delivers inert gas into the aluminum profile during bending, which reduces the problems of collapse and internal wrinkling of the aluminum profile, improves the processing quality, and the deformation of the third spring allows the position of the gas delivery head to be flexibly adjusted according to the bending position on the aluminum profile. 4. This invention, by setting a first connecting rod, a storage frame, a feeding plate, and a pushing bar on the frame, allows aluminum profiles to be bent to be stored in the storage frame. The pushing bar, moving within the storage frame, sequentially pushes the aluminum profiles onto the feeding plate and the pallet for feeding. The frame is equipped with a driving plate, a sliding strip, a protrusion, a telescopic rod, and a fifth spring. The driving plate is connected to one end of the pushing bar via a second connecting rod. A roller is fitted onto a fixed shaft on one of the driving rods. One end of the feeding plate is connected to a limiting strip that adheres to the bottom of the pallet. When the first hydraulic cylinder moves the pallet down onto the limiting strip, the stretching of the first spring causes the lifting plate to continue moving down, causing the roller to roll on the driving plate. This pushes the lifting plate along the frame, automatically moving the pushing bar within the storage frame, thus achieving automatic feeding and further improving work efficiency.

[0016] The following is in conjunction with the appendix Figures 1-9 The present invention will be described in further detail below.

[0017] Reference Figure 1 , Figure 3 and Figure 5This invention discloses a forming device for aluminum profiles, including a frame 1, side wing plates 2, and a bending die 4. The top of the frame 1 is bolted to the side wing plates 2. A rotating shaft 3 passes between the two side wing plates 2, and the bending die 4 is fixedly mounted on the rotating shaft 3. A protective structure and an automatic bending structure are installed on the frame 1. A horizontal plate 9 is fixedly connected between the two side wing plates 2 below the bending die 4, extending beyond the two side wing plates 2. An opening 5 is provided at the top of the frame 1. A fixing plate 6 is fixedly connected inside the frame 1 below the horizontal plate 9. A first hydraulic cylinder 7 is fixedly mounted on the fixing plate 6. A lifting plate 10 is connected to the top of the output shaft of the first hydraulic cylinder 7. A support plate 8 is provided above the lifting plate 10. First sleeves 13 are fixedly connected to both sides of the lower part of the support plate 8. First fixing rods 11 are fixedly connected to both sides of the upper part of the lifting plate 10. The first sleeves 13 are movably sleeved on the first fixing rods 11. A first spring 12 is connected between the bottom end of the first sleeve 13 and the lifting plate 10. The first spring 12 is sleeved on the first fixing rod 11. First sliding grooves are provided on both the front and rear sides of the lower part of the horizontal plate 9. Sliding blocks (not shown in the figure) are slidably installed in the first sliding grooves. The end faces of the sliding blocks and the first sliding grooves are both "T" shaped. Vertical plates 15 are connected to the bottom ends of both sliding blocks. First guide grooves 16 are provided on both vertical plates 15 (the shape of the first guide groove 16 is as follows...). Figure 3 As shown), driving rods 14 are connected to both the front and rear sides of the lifting plate 10. The two driving rods 14 movably pass through the corresponding first guide grooves 16. U-shaped strips 17 are fixedly connected to the upper positions of the two vertical plates 15 on opposite sides. A second fixing rod 18 is fixedly connected to one end of the U-shaped strip 17 extending onto the horizontal plate 9. A second sleeve 20 is movably sleeved on the second fixing rod 18. A second spring 19 is connected between one end of the second sleeve 20 and the end of the U-shaped strip 17. The second spring 19 is sleeved on the second fixing rod 18. Clamping blocks 23 are fixedly installed at the ends of the two second sleeves 20 that are close to each other. Insertion rods 21 are fixedly connected to the second sleeves 20, and the insertion rods 21 are set perpendicular to the second sleeves 20. Second guide grooves 22 are opened on the horizontal plate 9 at positions corresponding to the insertion rods 21 (the shape of the second guide grooves 22 is as shown in the image). Figure 3 and Figure 5As shown), the bottom end of the insertion rod 21 is inserted into the second guide groove 22. When the first hydraulic cylinder 7 is activated, it moves the support plate 8 upward into the opening 5. One end of the support plate 8 presses against the bottom of the horizontal plate 9. At this time, the first hydraulic cylinder 7 continues to move the lifting plate 10 upward, the support plate 8 stops moving, and the first spring 12 is compressed. In this way, the lifting plate 10 drives the driving rod 14 to slide in the first guide groove 16, thereby pulling the vertical plate 15 on the horizontal plate 9 to move the clamping block 23. The vertical plate 15 moves... At the same time, the bottom end of the insertion rod 21 slides in the second guide groove 22. Under the guidance of the inclined groove wall at the end of the second guide groove 22, the second sleeve 20 moves by stretching the second spring 19 on the second fixed rod 18, so that the two clamping blocks 23 move towards each other to clamp onto the aluminum profile. The aluminum profile is also automatically moved on the horizontal plate 9 to the bottom of the bending die 4, realizing automatic feeding, improving the processing efficiency of aluminum profiles, and making the operation more labor-saving and convenient. The automatic bending structure includes a second hydraulic cylinder 63 rotatably mounted inside the frame 1. A rotating shaft 3 extends through both ends of the side wing plate 2 and is fixedly fitted with a rotating handle 24. The top end of the output shaft of the second hydraulic cylinder 63 is rotatably connected to the connecting shaft between the two rotating handles 24. When the second hydraulic cylinder 63 is started, it can drive the rotating shaft 3 and the bending die 4 to rotate as a whole to perform bending work on the pushed aluminum profile.

[0018] See Figure 1 , Figure 3 and Figure 4 The protective structure includes a high-pressure air source 25 installed at the bottom of the frame 1. A gas supply pipe 26 is connected to the high-pressure air source 25. A gas supply head 27 is installed at one end of the gas supply pipe 26. During bending, inert gas can be introduced into the aluminum profile through the high-pressure air source 25. During the bending process, the problem of aluminum profile collapse and internal wrinkling is reduced, and the processing quality is improved. L-shaped rods 29 are connected to the lower positions of both sides of the bending die 4. One end of each L-shaped rod 29 is connected to an end block 30. Each L-shaped rod 29 is fitted with a movable sleeve block 31. A movable sleeve 28 is connected between the two sleeve blocks 31. The movable sleeve 28 is fixedly fitted onto the gas delivery head 27. A third spring 32 is fitted onto the L-shaped rod 29. The two ends of the third spring 32 are respectively connected to the end block 30 and the sleeve block 31. When the clamping block 23 clamps the aluminum profile and sends it to the lower position of the bending die 4, it can drive one end of the aluminum profile to automatically fit onto the gas delivery head 27 for inert gas delivery. Furthermore, by using the movement of the sleeve block 31 on the L-shaped rod 29, the third spring 32 is compressed. The position of the gas delivery head 27 can be automatically adjusted according to the actual bending position of the aluminum profile, making it more flexible to use. A groove 35 is provided at one end of the support plate 8. An adjusting strip 36 is movably inserted into the lower part of the groove 35, and a stop block 40 is movably inserted into the upper part of the groove 35. Both ends of the stop block 40 are connected to first guide rods 37. The bottom end of the first guide rod 37 is movably inserted into a hole on the stop block 40. A fourth spring 38 is fitted onto the first guide rod 37, and both ends of the fourth spring 38 are connected to the adjusting strip 36 and the stop block 40, respectively. A screw 41 rotatably passes through the support plate 8. A turntable 42 is fixedly fitted onto one end of the screw 41, and the other end of the screw 41 is inserted into a threaded groove on the stop block 40. A limit block 39 is provided on the support plate 8 below one end of the stop block 40. The stop block 40 can limit the aluminum profile on the support plate 8, so that after the clamping block 23 clamps the aluminum profile, it can transport the part of the aluminum profile to be bent to the lower part of the bending die 4 for bending, thereby improving the bending quality. In addition, the stop block 40 can be flexibly adjusted on the support plate 8 to limit the aluminum profile according to the part of the aluminum profile to be bent by rotating the screw 41 using the turntable 42, making it more flexible to use. At the same time, when the support plate 8 moves up into the opening 5, the horizontal plate 9 can push the stop block 40 down into the groove 35, releasing the limit on the aluminum profile on the support plate 8, so that the clamping block 23 can smoothly clamp the aluminum profile and send it to the lower part of the bending die 4 for bending.

[0019] See Figure 1 , Figure 2 , Figure 8 and Figure 9 A storage frame 43 is provided on the frame 1 at the position of the tray 8 (the shape of the storage frame 43 is as follows). Figure 8 As shown), the storage frame 43 is connected to the frame 1 by two first connecting rods 44. The storage frame 43 has a feeding port 46 at the lower part of the side near the pallet 8. The side of the storage frame 43 is connected to the feeding port 46. The pusher bar 47 inserted into the feeding plate 45 moves through the storage frame 43. The end of the feeding plate 45 away from the storage frame 43 is connected to two limiting bars 62. The limiting bars 62 are "L" shaped and are close to the bottom of the pallet 8. The storage frame 43 can be used to store a large number of aluminum profiles to be bent. When the pusher bar 47 moves back and forth, the aluminum profile at the bottom of the storage frame 43 can be intermittently sent to the feeding plate 45 and the pallet 8. A drive plate 51 is provided on the rear side of the frame 1, and a slide bar 52 is provided on the front side of the drive plate 51. A second slide groove 54 is provided on the frame 1 for the slide bar 52 to slide. The end faces of the slide bar 52 and the second slide groove 54 are both "T" shaped. The upper part of the drive plate 51 is inclined. A fixed shaft 49 is fixedly connected to a drive rod 14 near the drive plate 51. A roller 50 is movably sleeved on the fixed shaft 49 and is rolled on the drive plate 51. A second connecting rod 48 is connected to the rear side of the drive plate 51. One end of the second connecting rod 48 is connected to the end of the push bar 47 away from the feed plate 45. A protrusion 53 is connected to one end of the slide bar 52. The protrusion 53 is connected to the frame 1. There is a telescopic rod 55, and a fifth spring 56 is sleeved on the telescopic rod 55. The two ends of the fifth spring 56 are respectively connected to the protrusion 53 and the frame 1. When the first hydraulic cylinder 7 drives the pallet 8 to move down to the limit bar 62, the first hydraulic cylinder 7 can continue to drive the lifting plate 10 to move down, stretch the first spring 12, so as to drive the roller 50 to roll on the upper inclined surface of the driving plate 51, and squeeze and push the driving plate 51 to move on the frame 1. The second connecting rod 48 pulls the push bar 47 to move, and automatically pushes out the aluminum profile at the bottom of the storage frame 43 for loading. When the lifting plate 10 moves up, the elastic force of the fifth spring 56 can be used to reset the driving plate 51 and the push bar 47 as a whole.

[0020] See Figure 1 , Figure 6 and Figure 7 Movable sleeves 61 are movably fitted on both sides of the bending mold 4 on the rotating shaft 3. Locking plates 57 extending to the bottom of the bending mold 4 are connected to the movable sleeves 61. Multiple second guide rods 58 are connected to the movable sleeves 61 and are movably inserted into the bending mold 4. A sixth spring 59 is fitted on each of the second guide rods 58, with both ends of the sixth spring 59 connected to the movable sleeves 61 and the bending mold 4, respectively. Fixed cylinders 34 are fixedly connected to the inner sides of the side wing plates 2 at the position of the rotating shaft 3. A third guide groove 33 is provided on the fixed cylinder 34 (the shape of the third guide groove 33 is as follows...). Figure 7 As shown), a through rod 60 is inserted into the third guide groove 33. One end of the through rod 60 is connected to the movable sleeve 61. When the second hydraulic cylinder 63 drives the rotating handle 24, the rotating shaft 3 and the bending die 4 to rotate as a whole, it drives one end of the through rod 60 to slide in the third guide groove 33. By using the push of the through rod 60 by the third guide groove 33, the movable sleeve 61 is driven to move on the rotating shaft 3 towards the side closer to the bending die 4, thereby driving the locking plate 57 to move to the bottom of the aluminum profile to firmly fix the aluminum profile, so that the aluminum profile can be bent smoothly.

[0021] The implementation principle of a forming device for aluminum profiles according to an embodiment of the present invention is as follows: First, the aluminum profile to be bent is placed in the storage frame 43, and the screw 41 is rotated on the pallet 8 using the turntable 42. The position of the stop block 40 in the groove 35 is adjusted according to the actual needs. Then, the first hydraulic cylinder 7 is started to drive the lifting plate 10 to move downward. Under the limiting action of the limiting strip 62 on the pallet 8, the pallet 8 is in a stationary state. The downward movement of the lifting plate 10 drives the roller 50 on the fixed shaft 49 to roll on the inclined surface of the driving plate 51, pushing the driving plate 51 to drive the slide strip 52 to slide in the second slide groove 54, compressing the fifth spring 56, and driving the pusher strip 47 to slide in the storage frame 43 through the second connecting rod 48, thus pushing the material in the storage frame 43 to slide. The bottom aluminum profile is pushed onto the loading plate 45 and the pallet 8, with one end of the aluminum profile pressed against the stop block 40. Then, the first hydraulic cylinder 7 drives the lifting plate 10 to move upward, thereby moving the pallet 8 upward and lifting the aluminum profile on the loading plate 45. When the pallet 8 moves upward into the opening 5, the horizontal plate 9 presses the stop block 40 downward, pushing the stop block 40 into the groove 35, releasing the restriction on the aluminum profile on the pallet 8. When the stop block 40 moves downward onto the limiting block 39, it can limit the pallet 8 within the opening 5, and the pallet 8 stops moving upward. Then, the first hydraulic cylinder 7 drives the lifting plate 10 to continue moving upward, causing the first spring 12 to compress, thereby causing the driving rod 14 to slide in the first guide groove 16 on the vertical plate 15. The vertical plate 15 drives the second set of The insertion rod 21 on the tube 20 slides in the second guide groove 22, and in conjunction with the guiding action of the second guide groove 22 on the insertion rod 21, it can drive the clamping block 23 to move and clamp onto the aluminum profile, clamping and conveying the aluminum profile to the lower part of the bending die 4. One end of the aluminum profile is fitted onto the air supply head 27, and then inert gas is introduced into the aluminum profile through the high-pressure air source 25. The second hydraulic cylinder 63 is activated to drive the rotating shaft 3 and the bending die 4 to rotate. During the rotation, the through rod 60 slides in the third guide groove 33, pushing the locking plate 57 to the lower part of the aluminum profile to lock the aluminum profile, so that the bending die 4 can automatically perform bending work when rotating, making the operation more labor-saving and convenient, and improving work efficiency. At the end of the bending, it is pulled open from one end of the aluminum profile. The air supply head 27 and the second hydraulic cylinder 63 drive the bending die 4 to reset, thereby releasing the locking plate 57 from the aluminum profile. The first hydraulic cylinder 7 drives the lifting plate 10 to continue moving upward, causing the insertion rod 21 to slide to the end of the second guide groove 22. The second spring 19 pulls the second sleeve 20 and the clamping block 23 to reset as a whole, thus releasing the aluminum profile. Finally, when the first hydraulic cylinder 7 drives the lifting plate 10 to move downward, it drives the vertical plate 15 to move in the opposite direction. Under the guidance of the inclined surface at the end of the second guide groove 22, the clamping block 23 is always in a loose state on the aluminum profile when the insertion rod 21 moves in the opposite direction. In this way, the lifting plate 10 can smoothly drive the support plate 8 to move downward to unload the bent aluminum profile, thus realizing the bending work of the aluminum profile.

[0022] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
