Description

Technical Field

[0001] This utility model relates to the field of sheet metal cutting technology, specifically to an aluminum sheet cutting device. Background Technology

[0002] Aluminum sheets, as an important metallic material, are widely used in construction decoration, transportation, electronics, and other fields. In practical applications, it is often necessary to cut long aluminum sheets into shorter sheets of specific lengths to meet different needs. Traditional aluminum sheet cutting methods mainly include shearing, sawing, and laser cutting. Among these, mechanical shearing is more commonly used in batch cutting due to its high efficiency and relatively low cost.

[0003] Existing aluminum sheet cutting equipment typically includes a lifting cutter and a platform to hold the aluminum sheet. This platform has a horizontal support surface for placing the aluminum sheet and an inclined feed ramp connected to one end of the support surface to facilitate the sliding of the sheet after cutting. To ensure a consistent length of the short aluminum sheet obtained with each cut, the sheet needs to be pushed out a predetermined distance along its length before each cut. However, when the required length of the short aluminum sheet to be cut is long, the downward-sloping feed ramp at one end of the platform prevents the overhanging portion of the sheet from receiving effective support from the platform. This insufficient support easily leads to bending and deformation of the aluminum sheet, affecting cutting quality and hindering subsequent production processes. Furthermore, current aluminum sheet feeding operations largely rely on manual positioning (such as manually pushing it under the cutter after marking lines), resulting in errors in the feeding distance and poor cutting length accuracy. Although devices capable of precisely feeding aluminum sheets exist, their complex structure and high purchase cost significantly increase equipment investment. Utility Model Content

[0004] The purpose of this utility model is to provide an aluminum plate cutting device that can effectively support the aluminum plate during cutting, prevent the overhanging part from bending, facilitate subsequent production, and effectively position the aluminum plate to improve the cutting length accuracy.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: an aluminum plate cutting device, comprising:

[0006] The base includes a bearing surface and a feeding ramp connected to one end of the bearing surface. A cutting groove extending in the width direction is provided on the bearing surface.

[0007] A lifting and cutting assembly is provided above the base and includes a cutting blade corresponding to the position of the blade groove;

[0008] The spacing assembly includes two support rods positioned above the feeding ramp and extending along the length of the bearing surface. The end of the support rod away from the bearing surface is provided with a support member. A spacing rod is slidably connected between the two support rods and fixed by a locking member. A support block is provided at the lower end of the spacing rod. The upper end surface of the support block is at the same level as the bearing surface to jointly support the aluminum plate.

[0009] A further improvement of this utility model is that a nylon groove is provided on the bearing surface, a nylon strip is provided in the nylon groove, and the knife groove is formed on the nylon strip.

[0010] A further improvement of this utility model is that the lifting and cutting assembly includes a bracket fixedly mounted on the base. The bracket includes symmetrically arranged columns and a crossbeam connecting the two columns. A hydraulic cylinder is provided on the crossbeam, and the telescopic end of the hydraulic cylinder is vertically downward and connected to the cutting blade.

[0011] A further improvement of this utility model is that the support block is slidably connected to the lower end of the spacer rod along the length direction of the spacer rod, the distance between the two support rods is greater than the sum of the width of the aluminum plate and the width of the support block, and an adjustment handle is connected to the end of the support block away from the bearing surface.

[0012] A further improvement of this utility model is that a mounting plate is fixedly connected to the telescopic end of the hydraulic cylinder, and the cutting blade is detachably mounted on the mounting plate.

[0013] A further improvement of this utility model is that vertical sliding grooves are symmetrically provided on the opposite surfaces of the two columns, and the two ends of the mounting plate are slidably connected in the vertical sliding grooves.

[0014] A further improvement of this utility model is that a vertical rod is provided on one side of the upper end of the mounting plate, and a sliding hole is provided on the crossbeam to slide with the vertical rod. Two limit switches are provided at intervals on one of the columns, and two stop blocks corresponding to the limit switches are provided at intervals on the vertical rod. The two limit switches correspond to the upper limit and lower limit of the mounting plate, respectively.

[0015] A further improvement of this utility model is that two limit switches are located on both sides of the vertical rod's movement direction, and two impact blocks are fixedly installed on both sides of the vertical rod and cooperate with the limit switches on their respective sides.

[0016] A further improvement of this utility model is that the support rod is provided with a sliding groove along its length direction, a slider is slidably connected in the sliding groove, a through hole is provided on the slider and the end of the spacer rod, and a waist hole is provided at the bottom of the sliding groove along its length direction. The locking member is a bolt that passes through the through hole and the waist hole, and the bolt is fixed by the cooperation of the nut and its head.

[0017] A further improvement of this utility model is that a hydraulic station is provided on one side of the base, and the hydraulic station is driven and connected to the oil cylinder.

[0018] The beneficial effects of this utility model are as follows:

[0019] This invention effectively solves the problem of overhang support when pushing out long aluminum plates by setting two support rods and a sliding spacer rod above the inclined surface of the material cutting plane, and installing a support block flush with the bearing surface at the lower end of the spacer rod. The support block provides rigid support for the overhanging part of the aluminum plate, preventing it from bending and deforming due to its own weight, ensuring the flatness of the cut surface and the quality of subsequent processing; at the same time, the spacer rod is fixed in position by locking parts, which can accurately control the pushing distance of the aluminum plate, replacing manual positioning, significantly improving the cutting length accuracy, and at a lower cost.

[0020] The support block of this invention slides along the fixed-distance rod, and the distance between the support rods is greater than the sum of the widths of the aluminum plate and the support block. This allows the support block to move laterally out of the aluminum plate conveying path, avoiding interference with the cutting of the aluminum plate. Furthermore, the lateral position of the support block can be quickly adjusted by adjusting the handle to adapt to the needs of cutting aluminum plates of different widths and the need for support block avoidance, thus improving the versatility of the device.

[0021] This invention achieves automatic limit control of the hydraulic cylinder's lifting stroke by using a vertical rod and a horizontal beam with sliding holes, combined with the linkage of impact blocks and limit switches. Two impact blocks are positioned on either side of the vertical rod and correspond to limit switches on the same side, allowing the lifting and lowering limit signals to be triggered independently. This prevents malfunctions, ensures the hydraulic cylinder operates within its safe stroke, prevents mechanical interference, and prevents damage to the platform from excessive downward pressure or damage to components from excessive upward pressure.

[0022] This invention features a nylon groove on the bearing surface and a nylon strip with a blade groove. The nylon strip buffers the cutting impact, reduces blade wear, and extends the service life of the cutting blade. Attached Figure Description

Detailed Implementation

[0029] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0030] Example 1: Combination Figures 1-5 It is known that an aluminum sheet cutting device includes:

[0031] The base 1 includes a bearing surface 2 and a feeding slope 3 inclined to one end of the bearing surface 2. A knife groove 4 extending in the width direction is provided on the bearing surface 2.

[0032] The lifting and cutting assembly is located above the base 1 and includes a cutting blade 5 corresponding to the position of the blade groove 4;

[0033] The spacing assembly includes two support rods 6 positioned above the unloading ramp 3 and extending along the length of the bearing surface 2. A spacing rod 7, secured by a locking device, is slidably connected between the two support rods 6. A support block 8 is provided at the lower end of the spacing rod 7, and the upper surface of the support block 8 is at the same level as the bearing surface 2 to jointly support the aluminum plate. The extension direction of the spacing rod 7 is parallel to the width direction of the bearing surface 2. Preferably, a support element, such as a pad or vertical support rod, is provided at the end of the support rod 6 away from the bearing surface.

[0034] The bearing surface 2 has a nylon groove, within which a nylon strip 9 is installed. A cutting groove 4 is formed on the nylon strip 9. The top surface of the nylon strip 9 is flush with the bearing surface 2. The cutting groove 4 extends through the entire width of the nylon strip 9. The nylon strip 9 can be designed as a segmented or integral piece, and can be replaced individually after wear.

[0035] The lifting and cutting assembly includes a bracket fixedly mounted on the base 1. The bracket includes symmetrically arranged columns 10 and a crossbeam 11 connecting the two columns 10. A hydraulic cylinder 12 is mounted on the crossbeam 11. The telescopic end of the hydraulic cylinder 12 is vertically downward and connected to a cutting blade 5.

[0036] A mounting plate 14 is fixedly connected to the telescopic end of the hydraulic cylinder 12, and the cutting blade 5 is detachably mounted on the mounting plate 14. The cutting blade 5 is detachably mounted below the mounting plate 14 by means of bolts or quick-change chucks, which facilitates replacement or sharpening. The cutting edge of the cutting blade 5 faces the blade groove 4 below.

[0037] In this invention, the support block 8 can be directly welded or bolted to the bottom of the spacer rod 7. After cutting, the front end of the cut aluminum plate is still supported by the support block 8, and the rear end is supported by the bearing surface 2. At this time, the operator needs to manually remove the cut aluminum plate from the support block 8 and the bearing surface 2.

[0038] In this invention, the support block 8 can be slidably connected to the lower end of the spacer rod 7 along its length. After cutting, the support block 8 can be moved away from the area directly above the cutting slope 3, clearing a path and avoiding interference with the cutting of the aluminum plate. At this time, the distance between the two support rods 6 is greater than the sum of the width of the aluminum plate and the width of the support block 8. Preferably, this distance is 50-100mm larger than the sum of the width of the aluminum plate and the width of the support block 8, leaving sufficient space for the movement of the support block 8, ensuring that the support block 8 can be completely moved away without hindering the falling of the aluminum plate.

[0039] Preferably, the end of the support block 8 away from the bearing surface 2 is connected to an adjustment handle for easy movement.

[0040] Preferably, the support block 8 is fitted under the spacer rod 7 via a guide structure on its upper part (for example, the support block 8 has a hole or groove on its upper part that matches the cross-sectional shape of the spacer rod 7), and can slide manually along the spacer rod 7. At the sliding connection between the support block 8 and the spacer rod 7, a positioning pin, a set screw, or a friction pad can be provided so that the support block 8 can remain in a stable position when not operated manually, and can only be moved by applying a certain force by adjusting the handle when material discharge is required.

[0041] Two vertical grooves 15 are symmetrically provided on opposite surfaces of the two columns 10, and the two ends of the mounting plate 14 are slidably connected within the vertical grooves 15. Preferably, the two ends of the mounting plate 14 are slidably connected within the corresponding vertical grooves 15 by sliders or rollers, ensuring that the mounting plate 14 and the cutting blade 5 can only be raised and lowered smoothly in the vertical direction.

[0042] A vertical rod 16 is provided on one side of the upper end of the mounting plate 14. A sliding hole is provided on the crossbeam 11 to slide with the vertical rod 16. Two limit switches 17 are provided at intervals on one of the columns 10. Two stop blocks 18 corresponding to the limit switches 17 are provided at intervals on the vertical rod 16. The two limit switches 17 correspond to the upper limit and lower limit of the mounting plate 14, respectively. Preferably, the two stop blocks 18 (such as metal blocks) are firmly fixed to the vertical rod 16 with screws, and the two limit switches 17 are firmly fixed to the column 10 with mounting brackets. Their positions are precisely set according to the highest safe rising point of the cutting blade 5 (to avoid collision with the crossbeam) and the lowest cutting point (the blade tip is fully inserted into the blade groove 4 with a margin).

[0043] Two limit switches 17 are located on both sides of the vertical rod 16 in the direction of movement, and two stop blocks 18 are fixedly installed on both sides of the vertical rod 16 and cooperate with the limit switches 17 on their respective sides. Preferably, the limit switches are JLXK1-111 limit switches from Zhejiang Tianzheng Electric Co., Ltd.

[0044] Specifically, see Figure 5 When the mounting plate 14 drives the cutting blade 5 to its highest point, the upper stop block 18 on the vertical rod 16 contacts and triggers the left-side limit switch 17, sending a stop signal. When the mounting plate 14 drives the cutting blade 5 to its cutting completion position, the lower stop block 18 on the vertical rod 16 contacts and triggers the right-side limit switch 17, sending a stop signal. All limit switches 17 are electrically connected to the controller (a conventional controller in the prior art, which may be a PLC). When the descent limit switch is triggered, the controller sends a signal to the hydraulic system, controlling the cylinder 12 to stop descending and maintain or begin ascending. When the ascending limit switch is triggered, the controller controls the cylinder 12 to stop ascending.

[0045] The support rod 6 has a groove along its length, and a slider 19 is slidably connected in the groove. The slider 19 and the end of the spacer rod 7 have through holes. The bottom of the groove has a waist hole along its length. The locking element is a bolt 20 that passes through the through hole and the waist hole. The bolt 20 is fixed to the spacer rod by engaging with its head with a nut. After loosening the bolt 20 and the nut, the spacer rod 7 can be slid along the waist hole to adjust its distance from the cutting blade 5 (i.e., the cutting length of the aluminum plate). After adjustment, it can be locked.

[0046] A hydraulic station 21 is provided on one side of the base 1. The hydraulic station 21 is connected to the oil cylinder 12 for drive. The hydraulic station provides a stable power source for the oil cylinder to ensure that the cutting pressure is sufficient and controllable.

[0047] The working principle of Embodiment 1 of the aluminum plate cutting device provided by the utility model is as follows:

[0048] During operation, a long aluminum plate is placed on the bearing surface 2 of the device. According to the required cutting length, the spacer rod 7 is slid along the two support rods 6 to the preset position and then locked in place. At this time, the support block 8 at the lower end of the spacer rod 7 is located in front of the bearing surface 2, and its upper surface is flush with the bearing surface 2. The aluminum plate is pushed forward along the bearing surface 2 until its front end abuts against the side of the spacer rod 7, achieving precise positioning. Simultaneously, the portion of the aluminum plate extending beyond the bearing surface 2 is stably supported by the support block 8, effectively preventing bending and deformation. The hydraulic cylinder 12 is activated, driving the cutting blade 5 downwards to cut the aluminum plate. After cutting, the cutting blade 5 rises back to its original position. At this time, the operator slides the support block 8 laterally by adjusting the handle, moving it away from the area directly above the feeding ramp 3, opening a passage. The cut short aluminum plate, no longer obstructed by the support block 8, naturally slides smoothly down the feeding ramp 3 under gravity and is discharged. Then, the support block 8 is slid back to its original position, allowing for the next cycle of aluminum plate advancement, positioning, and cutting.
