Description

Technical Field

[0001] This invention belongs to the field of forging and pressing machine tool technology. More specifically, it relates to a simple, non-powered auxiliary blanking mechanism for nickel plate shearing machines, which provides the best solution to the problem that the material support device and the blanking device cannot be used simultaneously when shearing narrow strips with a width of less than 40mm in nickel plate. Background Technology

[0002] With the increasing market demand for nickel and cobalt, manufacturers are also increasing their need for nickel-cobalt plate shearing machines. The sizes of the sheared strips are also becoming more varied. Each plate, regardless of width, requires a support device during shearing. The first few cuts require an anti-twisting device, and the final cut uses the support device. The support mechanism's function is to hold the rear end to prevent it from shifting the center of gravity and falling out before shearing, thus affecting the pace of subsequent processes. However, for good support, the support area needs to be large enough for stability. Furthermore, the weight distribution of nickel-cobalt electrolytic plates is extremely uneven, and the surface is rough. If a large support area is used, such as in CN119346969A (a pneumatic support and anti-twisting multi-functional device and method for shearing machines), the large support area results in a high probability that the strip will remain on the support platform after shearing and cannot be dropped into the next process. While a small support area can partially solve the dropping problem, it cannot simultaneously fulfill the support function. This situation is indeed the case in actual use, leading to a low automation rate for such production lines in China. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0004] A simple, non-powered auxiliary material feeding mechanism for a nickel plate shearing machine includes:

[0005] The carriage is vertically installed behind the shearing machine's worktable via a linear guide rail. The top of the carriage is equipped with multiple material support plates, and a material drop port is provided between two adjacent material support plates.

[0006] Welding electrodes are provided and installed on the shearing machine worktable below the material discharge port;

[0007] Mounting base, the mounting base is fixedly installed on the welding rod;

[0008] Gas spring, the gas spring is mounted on the mounting base;

[0009] The material support head is installed on top of the gas spring and is movably positioned inside the material drop port.

[0010] In the aforementioned simple, non-powered auxiliary blanking mechanism for nickel plate shearing machines, the mounting base is provided with a notch groove, and the notch groove corresponds to the position of the welding rod.

[0011] In the aforementioned simple, non-powered auxiliary material feeding mechanism for nickel plate shearing machines, the auxiliary material feeding mechanism also includes a guide member, which is mounted on a mounting base, and the top of the guide member is mounted on a material support head.

[0012] In the simple, non-powered auxiliary material feeding mechanism for nickel plate shearing machines, the guide component is a guide optical shaft, and a linear bearing is installed on the mounting base. The linear bearing and the guide optical shaft are installed together.

[0013] In the simple, non-powered auxiliary feeding mechanism for nickel plate shearing machines, a pressure cover is installed on the mounting base, and a dustproof ring is installed inside the pressure cover. The pressure cover and the dustproof ring are fitted onto the outside of the gas spring and the guide.

[0014] In the simple, non-powered auxiliary feeding mechanism for nickel plate shearing machine, the top of the material support plate is provided with a support plane, and the difference between the width of the support plane and the width of the material support head is ±5mm.

[0015] In the simple, non-powered auxiliary material feeding mechanism for nickel plate shearing machine, a sliding plate is installed obliquely downwards on the slide.

[0016] A simple, non-powered auxiliary material feeding method for nickel plate shearing machines, employing the aforementioned simple, non-powered auxiliary material feeding mechanism for nickel plate shearing machines, comprises the following steps:

[0017] Step 1, Preparation

[0018] The nickel plate is placed between the upper and lower cutting edges to await shearing. The latter half is supported by the material support plate and the material support head to ensure the shearing dimensions.

[0019] Step 2, Cutting Operation

[0020] As the upper blade moves downward, the nickel plate is cut off. The support plate and support head follow the upper blade downward to the bottom dead center. At this time, the gas spring compresses along with the upper blade and the nickel plate to the bottom dead center of the upper blade.

[0021] Step 3, return the upper blade.

[0022] The upper blade returns to the top dead center, at which point the carriage remains stationary for 1-3 seconds;

[0023] Step 4, nickel plate blanking

[0024] Once the gas spring loses the force of the upper blade, it automatically rebounds, lifting the nickel strip above and smoothly sliding it from the top of the support plate to the sliding plate, allowing it to smoothly enter the next process.

[0025] Compared with the prior art, the present invention has the following significant advantages:

[0026] 1. This invention utilizes an independent sliding frame and multiple spaced-apart support plates at the top, with a spring-driven support head movably positioned within the drop opening between adjacent support plates. During shearing preparation and the shearing process, the support plates and support heads together form a stable supporting plane, effectively solving the problems of center of gravity shift and instability in narrow-faced material support caused by uneven weight distribution and surface irregularities in nickel-cobalt electrolytic plates, ensuring precise shearing dimensions. After shearing, the support plates temporarily stop for 1-3 seconds, the springs automatically return to their original position, and the support heads rise relative to the support plates, actively lifting one end of the cut narrow strip, allowing it to slide smoothly down under gravity. This design completely resolves the technical contradiction in traditional devices where "large support areas prevent material drop, while small support areas cause instability," achieving reliable material drop without additional power or complex control, effectively preventing strip material stagnation, and significantly improving automated production cycle time and production line coverage.

[0027] 2. This device uses only a gas spring as the power element. It relies entirely on the mechanical downward compression of the gas spring during the shearing process to store energy, and then releases the energy using the gas spring's own elasticity after the upper blade returns to its original position, thus achieving the material dropping action. The entire mechanism does not require external power sources such as cylinders, hydraulic cylinders, or motors, nor does it require corresponding sensors or solenoid valve control systems. This not only significantly simplifies the equipment structure, reduces manufacturing costs and installation difficulty, but also saves energy consumption, meeting the industrial demands for green manufacturing and low-cost automation.

[0028] 3. This device ensures the verticality and positional accuracy of the material support head during frequent up-and-down movements by adding a guide component consisting of a guide shaft and linear bearings to the mounting base. This effectively prevents lateral deformation or jamming of the gas spring piston rod caused by the impact of the nickel plate descending or uneven loading, ensuring the long-term stability and reliability of the device. Simultaneously, the dust seal installed inside the pressure cap effectively isolates metal dust generated during shearing, preventing dust from entering the gas spring and linear bearings, significantly reducing wear on key moving parts and extending the service life of the entire mechanism.

[0029] 4. The material dropping method of this invention has a clear logic. After the upper blade returns to the top dead center, the slide is kept stationary for 1-3 seconds to give the gas spring sufficient time to rebound, ensuring that the strip is effectively lifted and smoothly slides down to the slide plate. The action sequence is highly matched with the working cycle of the shearing machine, without the need for additional adjustment or manual intervention, realizing the automatic and seamless connection of the entire process of shearing, material support and dropping, and greatly reducing the labor intensity of operators.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0038] like Figures 1 to 5 As shown, a simple, non-powered auxiliary blanking mechanism for a nickel plate shearing machine includes:

[0039] The slide 10 is vertically installed behind the shearing machine worktable via a linear guide 11. The top of the slide 10 is provided with three material support plates 12. The width of the middle material support plate 12 is greater than the width of the material support plates 12 on both sides. The gap between the material support plates 12 on both sides and the middle material support plate 12 is provided with a material drop port 13 for the material support head 50 to move up and down.

[0040] Welding rods 20 are installed on the shearing machine worktable below the discharge port 13. Two welding rods 20 are installed below each discharge port 13 for fixing the mounting base 30.

[0041] Mounting base 30 is fixedly mounted on welding rod 20. The mounting base 30 has notches on both sides for mounting welding rod 20.

[0042] Gas spring 40 is mounted on mounting base 30 and connected to material support head 50 through the top of gas spring 40;

[0043] The material support head 50 is installed on top of the gas spring 40 and is movably arranged inside the material drop port 13.

[0044] At the starting position, the nickel plate is placed on top of the support plate 12 and flush with the top of the support head 50, or the top of the support head 50 is slightly lower than the top of the support plate 12 to ensure the cutting size. The upper blade moves downward, the nickel plate is cut, and the support plate 12 and the support head 50 follow the upper blade downward to the lower dead center. At this time, the gas spring 40 follows the upper blade and the nickel plate and is compressed to the lower dead center of the upper blade. The upper blade returns to the upper dead center. At this time, the slide 10 remains stationary for 1-3 seconds. There is a drive component (pneumatic cylinder or hydraulic cylinder) on one side of the slide 10. The slide 10 is driven by the shearing machine's own drive system (including the drive component) following the movement of the upper blade. At the same time as the upper blade moves downward, the output end of the drive component is pressed and performs a synchronous retraction action. At the same time as the support head 50 moves downward, the output end of the gas spring 40 retracts. The gas spring 40 loses the force of the upper blade and automatically rebounds, lifting the nickel plate strip above and smoothly sliding it from the top of the support plate 12 to the slide plate 70, smoothly entering the next process.

[0045] In one of the implementations, such as Figure 2 As shown, in the simple, non-powered auxiliary material feeding mechanism for nickel plate shearing machine, the auxiliary material feeding mechanism also includes a guide 60, which is mounted on the mounting base 30. The top of the guide 60 is mounted on the material support head 50 to ensure the vertical guiding action of the material support head 50 and prevent the nickel plate from deviating while descending.

[0046] The guide member 60 is a guide optical shaft, and a linear bearing 61 is installed on the mounting base 30. The linear bearing 61 and the guide optical shaft are installed together. The sliding cooperation between the guide member 60 and the linear bearing 61 prevents damping from affecting the effective reset of the piston rod of the gas spring 40.

[0047] In one implementation, the simple, non-powered auxiliary feeding mechanism for the nickel plate shearing machine, such as Figure 2 As shown, a pressure cover 31 is installed on the mounting base 30, and a dustproof ring is installed inside the pressure cover 31. The pressure cover 31 and the dustproof ring are fitted on the outside of the gas spring 40 and the guide member 60, which can prevent metal powder generated by shearing from entering the gas spring and the linear bearing, thus preventing premature damage to the device.

[0048] In one implementation, the simple, non-powered auxiliary feeding mechanism for the nickel plate shearing machine, such as Figure 5As shown, the top of the material support plate 12 is provided with a support plane, and the difference between the width of the support plane and the width of the material support head 50 is ±5mm. The slide plate 70 is installed obliquely downward on the slide frame 10.

[0049] like Figures 1 to 5 As shown, a simple, non-powered auxiliary material feeding method for a nickel plate shearing machine is described above. The method employs the simple, non-powered auxiliary material feeding mechanism for a nickel plate shearing machine as described, and the steps are as follows:

[0050] Step 1, Preparation

[0051] The nickel plate is placed between the upper and lower cutting edges to await shearing. The latter half is supported by the material support plate 12 and the material support head 50 to ensure the shearing dimensions.

[0052] Step 2, Cutting Operation

[0053] As the upper blade moves downward, the nickel plate is cut off. The material support plate 12 and the material support head 50 follow the upper blade downward to the bottom dead center. At this time, the gas spring 40 is compressed along with the upper blade and the nickel plate to the bottom dead center of the upper blade.

[0054] Step 3, return the upper blade.

[0055] The upper blade returns to the top dead center, at which point the carriage 10 remains stationary for 1-3 seconds;

[0056] Step 4, nickel plate blanking

[0057] When the gas spring 40 loses the force of the upper blade, it automatically rebounds, lifting the nickel strip above it so that it can smoothly slide from the top of the support plate 12 onto the sliding plate and smoothly enter the next process.

[0058] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made to the technical solutions and inventive concepts of the present invention should all be covered within the scope of protection of the present invention.
