Description

Technical Field

[0001] The utility model relates to the field of cast steel part processing, in particular to a gate cutting device for cast steel part processing. Background Technique

[0002] The gate, also known as the feed inlet, refers to a section of the channel from the runner to the mold cavity. It is the part with the smallest cross-section and the shortest length in the gating system. In the processing of cast steel parts, it refers to the inlet and channel through which the molten metal enters the mold during pouring. Its function is to accelerate the feeding by constricting the flow surface. The high shear rate can make the feeding have good fluidity, and the temperature increase effect of viscous heating also has the effect of increasing the material temperature and reducing the viscosity.

[0003] After the production of cast steel parts is completed, it is often necessary to separate the sprue cup and the casting through a specific cutting device. Most of the existing gate cutting devices for cast steel part processing are mostly fixed by workers placing the workpiece to be cut on the end face of the workbench, and then starting the cutting equipment composed of a cutting tool and a driving source to cut the casting.

[0004] In this way of cutting the casting gate, workers need to firmly hold the casting with great force. The hands and face are extremely close to the high-speed rotating grinding wheel, with a high risk factor, and the personal safety of the cutting personnel cannot be guaranteed. Moreover, during the cutting process, the casting cup cannot be quickly collected. After cutting, workers need to manually release the fixation and then clean the end face of the workbench before the next cutting can be carried out, which affects the overall work efficiency and is rather inconvenient. Content of the Utility Model

[0005] Based on this, the purpose of the utility model is to provide a gate cutting device for cast steel part processing to solve the technical problems mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A gate cutting device for cast steel part processing, including a workbench, one end of the workbench is fixedly installed with a motor, and the output end of the motor is fixedly installed with a reciprocating lead screw. One end of the reciprocating lead screw is movably installed with a movable plate, and a cutting device is fixedly installed inside the movable plate. A connecting rod is movably installed inside the movable plate, and one end of the connecting rod is fixedly installed with a pressing plate. A spring is sleeved outside the connecting rod, and the movable plate and the pressing plate are connected by the spring. One end of the movable plate is fixedly installed with an extension plate. One end of the workbench is fixedly installed with a placing plate, and an activity groove for the extension plate to move is opened inside the placing plate. A cleaning component for cleaning the end face of the workbench is movably installed inside the workbench.

[0007] By adopting the above technical solution, by providing components such as a placement plate, a pressing plate, a spring, a rack, a rotating rod and a pushing plate, when a worker uses this equipment to cut the casting gate, the workpiece to be cut only needs to be placed in the fixing groove inside the placement plate, and starting the cutting equipment and the motor can automatically cut the workpiece. And during the downward movement of the overall position of the movable plate, through the cooperation of the placement plate and the pressing plate, it can effectively ensure that the overall position of the workpiece will not change during the cutting process, ensuring the cutting effect. And after the movable plate moves down to a certain position, it drives the overall rotation of the rotating rod, so that the pushing plate can push the sprue cup remaining on the end face of the workbench and the waste chips generated by cutting after the cutting is completed, so that they enter the sieve mesh, and the impurities and the sprue cup are separated through the sieve mesh, which is convenient for subsequent workers to clean and reuse them, greatly improving its overall work efficiency and ensuring the cleanliness of the end face of the workbench.

[0008] The present utility model is further configured such that the cleaning assembly includes a rack, a rotating rod, a gear, a guide groove, a pushing plate, a guide block and a shielding cover. The rotating rod is movably installed inside the workbench, and a gear is fixedly installed at one end of the rotating rod. A rack meshing with the gear is fixedly installed on one side end face of the movable plate, and a through hole for the movement of the rack is opened inside the workbench.

[0009] By adopting the above technical solution, the rotatably installed rotating rod enables it to rotate inside the workbench. The rack meshes with the gear, so that when the rack contacts the gear, it will drive the gear and the rotating rod to rotate together, providing drive for controlling the movement of the pushing plate. The through hole provides space for the rack to move inside the workbench, preventing it from being blocked by the workbench and unable to drive the gear.

[0010] The present utility model is further configured such that a pushing plate is movably installed inside the workbench, and a guide block is fixedly installed at one end of the pushing plate. A guide groove matching the guide block is opened inside the rotating rod.

[0011] By adopting the above technical solution, the movably installed pushing plate enables it to move inside the workbench. The guide block fixed at one end thereof cooperates with the guide groove, so that the position of the pushing plate can be changed during the rotation of the rotating rod, thereby achieving the purpose of cleaning the end face of the workbench.

[0012] The present utility model is further configured such that a shielding cover is fixedly installed at one end of the workbench, and a second limiting groove for restricting the pushing plate is opened inside the workbench.

[0013] By adopting the above technical solution, the shielding cover can effectively prevent the waste chips generated during the cutting of the workpiece by the cutting equipment from being blocked to a certain extent. The second limiting groove can restrict the pushing plate and control its moving direction to prevent it from shifting.

[0014] The present utility model is further configured such that a storage box is movably installed inside the workbench, and a screen is movably installed inside the storage box. One end of the workbench is fixedly installed with a limiting rod for restricting the movable plate.

[0015] By adopting the above technical solution, the movably installed storage box and the screen facilitate the worker to take out the storage box from inside the workbench for cleaning, and at the same time pour out the sprue cup inside it for collection and reuse. The screen can separate the sprue cup from the waste chips, improving the cleaning efficiency of the worker. The limiting rod can impose a certain restriction on the movable plate to prevent it from rotating together with the reciprocating lead screw during the rising process, ensuring the cutting effect.

[0016] The present utility model is further configured such that one end of the pressing plate is fixedly installed with a limiting block, and a first limiting groove for restricting the limiting block is provided inside the extension plate.

[0017] By adopting the above technical solution, the cooperation of the limiting block and the first limiting groove can effectively control the moving direction and distance of the pressing plate inside the extension plate, effectively preventing it from separating from the extension plate under the elastic force of the spring and ensuring its fixing effect.

[0018] In summary, the present utility model mainly has the following beneficial effects:

[0019] By providing components such as a placement plate, a pressing plate, a spring, a rack, a rotating rod, and a pushing plate, when the worker uses this equipment to cut the casting sprue, the workpiece to be cut only needs to be placed in the fixing groove inside the placement plate, and starting the cutting equipment and the motor can automatically cut the workpiece. And during the downward movement of the overall position of the movable plate, through the cooperation of the placement plate and the pressing plate, it can effectively ensure that the overall position of the workpiece does not change during the cutting process, ensuring the cutting effect. And after the movable plate moves down to a certain position, it drives the overall rotation of the rotating rod, so that the pushing plate can, after the cutting is completed, push the sprue cup remaining on the end face of the workbench and the waste chips generated by the cutting, making them enter the screen. The screen separates the impurities from the sprue cup, facilitating subsequent cleaning and reuse by the worker, greatly improving its overall work efficiency and ensuring the cleanliness of the end face of the workbench.
