Description

Technical Field

[0001] This invention belongs to the field of industrial automation technology, and more specifically, relates to a material feeding device for a blanking line. Background Technology

[0002] Before industrial automation, each process, equipment, and personnel in a production workshop were independently configured. The task at each node was: receive materials from the previous process, process them, and then transfer them to the next process. This process was cumbersome, involved a lot of auxiliary time, and resulted in a long production cycle. At that time, the materials purchased were mostly pre-cut sheets and plates, which were compatible with the existing processes.

[0003] After industrial automation, each piece of equipment is arranged according to the process sequence, and there are dedicated conveying mechanisms for the transfer of materials between each process. These conveying mechanisms extend into the inner cavity of the press, greatly improving production efficiency. Purchasing sheet or sheet materials as raw materials would slow down the entire production rhythm. Therefore, large-scale production enterprises directly purchase coil materials for production.

[0004] To improve production efficiency, the presses in automated blanking lines have the shortest possible stroke, resulting in a very small internal cavity height. The clamping mechanism needs to extend into the press cavity, so the overall height of the clamping mechanism must also be small.

[0005] Existing sheet metal clamping mechanisms generally use a pair of rollers for clamping, such as Figure 1 As shown, the upper roller 22 is hinged at both ends to the slider 101, which is driven by the vertically arranged cylinder 14. The overall height of the clamping mechanism is large, and it is difficult to design a structure with a small overall height, which is sometimes impossible. The sheet metal clamping device can only be arranged outside the press, which occupies a large area and has low efficiency. Therefore, in the existing sheet metal clamping mechanism, the upper roller is hinged at both ends to the slider, and the slider itself is also a very bulky component. When the upper roller is raised and lowered, the vertical cylinder has to overcome the weight of the upper roller plus the two sliders, which results in a large load. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides a material clamping and conveying device for a blanking line, which solves the technical problems of existing clamping and conveying devices occupying a large vertical space and having a large lifting load on the cylinder.

[0007] The purpose and effect of the material feeding device for a blanking line of the present invention are achieved by the following specific technical means:

[0008] A blanking line plate clamping and feeding device includes a base, a clamping roller assembly on the top of the base, the clamping roller assembly including a lower roller and an upper roller, two sets of lower roller hinge supports on the top of the base, and the two ends of the lower roller are rotatably connected to the two sets of lower roller hinge supports respectively; an upper beam is provided above the base, and two sets of downward pressing assemblies are provided on one side of the upper beam, the two ends of the upper roller are rotatably connected to the two sets of downward pressing assemblies respectively, and a cylinder is provided on each of the two sets of downward pressing assemblies, and the two sets of cylinders are horizontally arranged.

[0009] In a preferred embodiment, the pressing assembly includes an upper roller bracket, which is fixedly mounted on one side of the upper beam.

[0010] In a preferred embodiment, the upper roller support is provided with a first fixed hinge interface and a second fixed hinge interface, and the two sets of cylinders are respectively fixedly hinged to the two sets of the second fixed hinge interfaces.

[0011] In a preferred embodiment, the pressing assembly further includes a rotating frame, which is rotatably hinged to the first fixed hinge interface.

[0012] In a preferred embodiment, the rotating frame is provided with a first movable hinge point, and one end of the upper roller is rotatably connected to the first movable hinge point; the upper roller is a non-powered roller.

[0013] In a preferred embodiment, a cylinder connector is connected to the pneumatic rod of the cylinder, and a second movable hinge point is also provided on the rotating frame. The cylinder connector and the second movable hinge point are rotatably hinged.

[0014] In a preferred embodiment, the base is provided with two sets of fixed supports at its top. On the corresponding side of each of the two sets of fixed supports, two sets of columns are connected. The adjacent side of each of the two sets of columns is connected to the upper beam.

[0015] In a preferred embodiment, a speed reducer base is provided on the top of the base, and a speed reducer motor is provided on one side of the speed reducer base.

[0016] In a preferred embodiment, a coupling is provided on the other side of the reducer base, and the main shaft of the geared motor passes through the reducer base and is connected to the coupling.

[0017] In a preferred embodiment, one end of the lower roller passes through one set of lower roller hinge supports and is connected to the coupling; the lower roller is a power roller.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. By using a cylinder, the clamping device is hinged to the upper roller support and arranged horizontally, which reduces the installation height of the device. The structure is compact and occupies less space, allowing it to easily extend into the inner cavity of the press. It is better adapted to narrow working spaces, solves the problem of large space occupation of traditional clamping devices, shortens the stroke of the clamping roller assembly, improves the working efficiency of the unloading line, and better meets the needs of narrow working spaces.

[0020] 2. By using a rotating frame, the upper roller is driven by the rotating frame when using this clamping device. The cylinders at both ends are synchronized by the rigidity of the rotating frame. This synchronization method is more effective than synchronous gear synchronization and improves stability. At the same time, the upper roller rotates with the rotating frame, and the cylinders only need to overcome the torque of the rotating frame and the upper roller, instead of directly bearing their own weight. This reduces the load on the cylinders and solves the problem of large cylinder lifting load in traditional clamping devices. This makes the device lighter during operation, reduces energy consumption, and improves operating efficiency. Moreover, the smaller load also reduces the risk of wear and damage to components such as cylinders, extending the service life of the device. In long-term production, this can save enterprises a lot of energy and maintenance costs, improving their economic benefits. Attached Figure Description

[0030] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solutions of the present invention, but should not be used to limit the scope of protection of the present invention.

[0031] Example:

[0032] As attached Figures 1 to 7 As shown:

[0033] This invention provides a sheet metal clamping and feeding device for a blanking line, comprising a base 11, a clamping roller assembly on the top of the base 11, the clamping roller assembly including a lower roller 21 and an upper roller 22, two sets of lower roller hinge supports 12 on the top of the base 11, and the two ends of the lower roller 21 being rotatably connected to the two sets of lower roller hinge supports 12 respectively; an upper beam 13 is provided above the base 11, and two sets of downward pressing components are installed on one side of the upper beam 13, with the two ends of the upper roller 22 being connected to the two sets of downward pressing components respectively; this structural arrangement ensures that the lower roller 21 can rotate stably on the one hand, and that the upper roller 22 can move with the downward pressing components on the other hand, shortening the distance between the lower roller 21 and the upper roller 22, thereby realizing the clamping and feeding of the sheet metal 26; it not only fully utilizes the clamping and feeding effect of the lower roller 21 and the upper roller 22 working together, but also provides a reliable support foundation for the operating mechanism of the entire clamping and feeding device.

[0034] The downward pressure drive of the lower roller 21 adopts a horizontally arranged cylinder 14, which improves the spatial layout of the entire device. Compared with the traditional vertical cylinder drive, the horizontally arranged cylinder 14 reduces the installation height of the entire device, making its structure more compact and greatly reducing the space occupied. This allows the clamping device to easily extend into the inner cavity of the press, better adapting to the narrow working space environment. Thanks to this low and compact structure, the actual working stroke of the clamping roller assembly is reduced, thereby improving the operating efficiency of the entire blanking line. At the same time, this spatial layout also better meets the usage requirements of narrow working environments and avoids the problem of excessive height occupation by traditional clamping devices.

[0035] Please see as follows Figure 2 , Figure 3 and Figure 4As shown, the pressing assembly includes an upper roller bracket 31, which is fixedly installed on one side of the upper beam 13. The upper roller bracket 31 is provided with two sets of hinge interfaces, namely a first fixed hinge interface 32 and a second fixed hinge interface 33. The horizontally arranged cylinder 14 is hinged to the second fixed hinge interface 33. The cooperation of the first fixed hinge interface 32 and the second fixed hinge interface 33 lays the foundation for the upper roller 22 to move with the action of the pressing assembly. At the same time, the hinged connection between the cylinder 14 and the second fixed hinge interface 33 further optimizes the load transmission path during the pressing process, ensuring the stable and reliable operation of the entire clamping system.

[0036] Please see as follows Figure 4 and Figure 5 As shown, the pressing assembly also includes a rotating frame 34. Specifically, a rotatable rotating frame 34 is mounted on the first fixed hinge interface 32. This rotating frame 34 is provided with a first movable hinge point 35, and one end of the upper roller 22 is rotatably connected to this first movable hinge point 35. Utilizing the rotational characteristics of the rotating frame 34, the upper roller 22 is driven to rotate in coordination, thereby achieving the clamping of the sheet material 26. It is worth mentioning that the upper roller 22 mentioned above is a non-powered roller, meaning that it does not directly drive the movement of the sheet material 26, but relies on the power transmission of the lower roller 21 to complete the clamping action. This transmission method avoids the additional power system investment for the upper roller 22, thus making the structure simpler and more compact. On the other hand, it can also ensure the coordinated cooperation between the upper roller 22 and the lower roller 21, improving the stability of the clamping process.

[0037] Please see as follows Figure 5 and Figure 6 As shown, a cylinder connector 15 is connected to the pneumatic rod of cylinder 14, and a second movable hinge point 36 is provided on the rotating frame 34. The cylinder connector 15 is rotatably hinged to this second movable hinge point 36. This structural arrangement allows the rotating frame 34 to rotate along the first fixed hinge interface 32 when the cylinder 14 pushes out the pneumatic rod. This transmission method, which relies on the cylinder 14 to directly drive the rotating frame 34, has a more stable and reliable advantage compared to the traditional synchronous gear mechanism. First, the rigid structure of the rotating frame 34 effectively ensures the synchronous cooperation between the lower roller 21 and the upper roller 22, avoiding the error accumulation problem that is prone to occur with synchronous gears. Second, this transmission method can also significantly reduce the load on the cylinder 14, because it only needs to overcome the torque of the rotating frame 34 and the upper roller 22, rather than bearing their own weight. This makes the operation of the cylinder 14 more energy-efficient and efficient, and makes the operation of the clamping device more stable and reliable.

[0038] The upper roller 22 rotates together with the rotating frame 34. This means that during operation, the cylinder 14 only needs to overcome the torque of the rotating frame 34 and the upper roller 22, rather than bearing their own weight, reducing the load on the cylinder 14 and making the clamping device more convenient and energy-efficient during operation. Compared with the traditional clamping device where the cylinder directly lifts the upper roller, the cylinder needs to overcome the load caused by the weight of the upper roller, which inevitably leads to higher energy consumption and lower operating efficiency. In this device, the load borne by the cylinder 14 is significantly reduced, which not only reduces energy consumption and improves overall operating efficiency, but also effectively extends the service life of the cylinder 14. It not only achieves a highly compact and synchronously stable structure, but also demonstrates excellent performance advantages in terms of usage efficiency and maintenance costs. In the long-term production process, it can save enterprises a lot of energy and maintenance costs and improve the economic benefits of enterprises.

[0039] Please see as follows Figure 2 As shown, two sets of fixed supports 16 are provided on the top of the base 11. Two sets of columns 17 are connected to the corresponding sides of the two sets of fixed supports 16. The adjacent sides of the two sets of columns 17 are connected to the upper beam 13. This support structure enables the columns 17 to bear the load and ensures that the upper beam 13 can be stably installed on the base 11. At the same time, the symmetrical arrangement of the two sets of fixed supports 16 further strengthens the overall rigidity of the entire device, enabling it to better resist various external impacts and vibrations.

[0040] Please see as follows Figure 2 As shown, a reducer base 23 is provided on the top of the base 11. A geared motor 24 is mounted on one side of the reducer base 23, and a coupling 25 is provided on the other side of the reducer base 23. The main shaft of the geared motor 24 passes through the reducer base 23 and is directly connected to the coupling 25. Through this cooperative structure of the geared motor 24 and the coupling 25, on the one hand, the introduction of the geared motor 24 can provide the required driving torque for the lower roller 21, ensuring that the clamping and feeding device can stably complete the pulling and feeding of the sheet 26; on the other hand, the connection method of the coupling 25 can effectively eliminate the adverse effects of vibration and eccentricity at the end of the geared motor 24 on the transmission system, thereby ensuring efficient power transmission.

[0041] Please see as follows Figure 2 As shown, one end of the lower roller 21 passes through one of the lower roller hinge supports 12 and is connected to the coupling 25; the lower roller 21 is a power roller.

[0042] The specific usage and function of this embodiment are as follows: When using this device, the cylinder 14 is activated to extend the cylinder connector 15, thereby driving the upper roller 22 on the rotating frame 34 to rotate, causing the upper roller 22 to swing downwards and press against the lower roller 21, thus achieving continuous feeding of the sheet metal 26; when the cylinder 14 retracts, the rotating frame 34 drives the upper roller 22 to swing upwards, causing the upper roller 22 to separate from the lower roller 21, at which point manual operation can be performed to feed the sheet metal 26; through the cooperation of the cylinder 14 and the rotating frame 34, the sheet metal 26 is continuously fed in. Compared to traditional clamping devices that use a vertical cylinder 14 mounted on top of the bed 104, which extends a pneumatic rod and then drives the slider 101 downward via gear 102 and rack 103 to press the lower roller 21 against the upper roller 22, this device eliminates the need to bear the weight of the upper roller 22 itself. This reduces the load on the cylinder 14, solves the problem of high cylinder lifting load in traditional clamping devices, and makes the device more convenient to operate, reduces energy consumption, and improves operating efficiency.
