Description
Technical Field
[0001] This utility model relates to the technical field of die-casting product manufacturing process equipment, specifically a die-casting product shearing device that utilizes compressed air conversion and pressurization. Background Technology
[0002] Die-casting presses are a common type of equipment used in product manufacturing. After production, the venting channels and gates of the products removed from the die-casting machine are complexly connected and difficult to remove. It is necessary to cut off some of the connecting parts, reduce support, and then gradually separate them individually. This process is usually done manually, which is physically demanding and hinders production volume. With the advancement of intelligent manufacturing and the shift from manual to automated robotic production, the removal of venting channels and gates has become an essential step. Removing venting channels and gates reduces volume interference in the raw product, facilitating the robot's ability to perform subsequent tasks. Therefore, designing a new shearing structure is crucial to addressing these issues. Utility Model Content
[0003] This invention provides a die-casting product shearing device that utilizes compressed air conversion and pressurization, which can solve the problem that the existing shearing of the exhaust channel and gate of die-casting products requires manual operation and is not conducive to increasing production.

By setting the gas-hydraulic booster cylinder, the upper shearing blade can be driven to rise and fall, cutting off the exhaust channel and gate of the die-casting product together with the lower shearing blade. It can cooperate with a robot to automatically cut off the exhaust channel and gate of the die-casting product. The shearing gap of the blade can be adjusted by adjusting the connecting plate to adapt to different usage environments.
[0005] Preferably, self-lubricating copper plates are installed on both sides of the connecting slider, which reduces jamming and frictional resistance during the shearing process of the connecting slider and plays a role in stabilizing lubrication and guiding.

[0007] Preferably, the adjusting connecting plate includes an upper plate and movable adjusting blocks symmetrically arranged on the lower side of the upper plate. The movable adjusting blocks are engaged with the upper plate through inclined contact. At least two adjusting screws pass through one of the movable adjusting blocks and are connected to the other movable adjusting block. The distance between the two movable adjusting blocks can be adjusted by adjusting the screws, thereby adjusting the distance between the upper plate and the mounting plate, and thus adjusting the initial distance between the upper shearing blade and the lower shearing blade.
[0008] Preferably, the extension rod of the gas-liquid booster cylinder is connected to the connecting slider via a floating shaft, which effectively avoids the misalignment caused by the direct thread connection, reduces the risk of shaft breakage and oil leakage, and effectively reduces the direct transmission of vibration during the shearing process to the cylinder body.

Detailed Implementation
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] like Figure 1-6 As shown, this embodiment addresses the problem that manual operation is required for shearing the exhaust channels and gates of existing die-cast products, which is detrimental to increasing production. It provides a die-casting product shearing device utilizing compressed air for pressurization. The device includes a pneumatic-hydraulic booster cylinder 1, with an adjusting connecting plate 2 installed at one end. A mounting plate 3 is connected to one side of the adjusting connecting plate 2, and a hydraulic shear body 4 is installed on the lower side of the mounting plate 3. A movable connecting slider 11 is installed inside the hydraulic shear body 4. The upper end of the connecting slider 11 is connected to the extension rod of the pneumatic-hydraulic booster cylinder 1, and an upper shearing blade 6 is installed at the lower end of the connecting slider 11. A lower shearing blade 5 facing the upper shearing blade 6 is installed at the lower end of the hydraulic shear body 4. By setting the pneumatic-hydraulic booster cylinder 1, the upper shearing blade 6 can be driven to rise and fall, cutting off the exhaust channels and gates of the die-cast products together with the lower shearing blade 5. This device can cooperate with a robot to automatically cut off the exhaust channels and gates of die-cast products. The shearing gap can be adjusted by adjusting the connecting plate 2 to adapt to different operating environments.
[0022] Specifically, the pneumatic-hydraulic booster cylinder 1 can be powered by compressed air, providing a shearing force of over 5 tons to the upper shearing blade 6. A relatively large space is left between the upper shearing blade 6 and the lower shearing blade 5, allowing for the cutting of venting channels and gates for various die-cast products. The mounting plate 3 is L-shaped, facilitating the installation of the entire device onto an automated production line.
[0023] In this embodiment, self-lubricating copper plates 12 are installed on both sides of the connecting slider 11, which reduces the jamming and frictional resistance during the shearing process of the connecting slider 11 and plays a role in stabilizing lubrication and guiding. Graphite blocks with self-lubricating effect can be evenly distributed on the self-lubricating copper plates 12, which can reduce the sliding resistance of the connecting slider 11.
[0024] In this embodiment, a maintenance cover plate 7 is installed on one side of the hydraulic shear body 4, and a detection switch 9 is installed inside the maintenance cover plate 7. A detection block 10 corresponding to the detection switch 9 is installed on one side of the connecting slider 11. The maintenance cover plate 7 facilitates the installation of the detection switch 9. The detection block 10 and the detection switch 9 work together to detect the position of the upper shearing blade 6, and work with the robot to achieve automatic processing.
[0025] In this embodiment, the adjusting connecting plate 2 includes an upper plate 21 and movable adjusting blocks 22 symmetrically arranged on the lower side of the upper plate 21. The movable adjusting blocks 22 are engaged with the upper plate 21 through inclined contact. At least two adjusting screws 8 pass through one of the movable adjusting blocks 22 and are connected to the other movable adjusting block 22. The distance between the two movable adjusting blocks 22 can be adjusted by adjusting the adjusting screws 8, thereby adjusting the distance between the upper plate 21 and the mounting plate 3, and thus adjusting the initial distance between the upper shearing blade 6 and the lower shearing blade 5.
[0026] In this embodiment, the extension rod of the gas-liquid booster cylinder 1 is connected to the connecting slider 11 via a floating shaft 13, which effectively avoids the skewing caused by the direct thread connection, reduces the risk of shaft breakage and oil leakage, and effectively reduces the direct transmission of vibration during the shearing process to the cylinder body.
[0027] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.
[0028] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly and specifically defined.
[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0030] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
