Description

Technical Field

[0001] The present application relates to the technical field of sand core casting, and in particular to a cold iron feeding system for sand core production. Background Art

[0002] One-piece cylinder heads are usually cast in two parts (cylinder head and cylinder body) together. The production of sand cores (chassis core and upper cover core) of one-piece cylinder heads requires a series of steps and then assembly. Depending on the different castings, the production of each sand core can be divided into chilled iron process and non-chilled iron process. When it is the chilled iron process, it is necessary to assemble the chill in the cold core box of the core making machine to complete the molding of the sand core. At present, the production process of the chassis core and upper cover core of the one-piece cylinder head requires manual transportation of the chill to the core making machine and placing the chill in the cold core box of the core making machine, which will lead to low production efficiency and poor product consistency and product quality stability. Utility Model Content

[0010] In some embodiments of the present invention, the chilled iron feeding system for sand core production further includes: a storage hopper, which is arranged on the chilled iron storage area and is used to store the chilled iron.

[0011] In some embodiments of the present invention, an edge of the storage hopper gradually decreases from a side away from the cold iron posture correction zone to a side close to the cold iron posture correction zone.

[0012] In some embodiments of the present invention, the storage hopper is movably placed on the cold iron storage area.

[0013] In some embodiments of the present invention, the industrial robot is arranged close to the cold iron storage area and the cold iron posture correction area.

[0022] The present application embodiment discloses a cold iron feeding system for sand core production. Figure 1 As shown, the chill feeding system for sand core production includes a base 710, an industrial robot 706 and a 2D vision detector 702, wherein a chill storage area, a chill posture correction area and a chill output area are formed on the base 710; the industrial robot 706 includes an electromagnetic suction cup gripper 704 and a 3D vision detector 705, which are used for the transfer of the chill; the 2D vision detector 702 is installed in the chill posture correction area, which is used to correct the position of the chill on the electromagnetic suction cup gripper 704.

[0023] By using the cold iron feeding system in the present technical solution, when sand cores of the cold iron process need to be produced, the electromagnetic suction cup gripper 704 grabs the cold iron at the cold iron storage area under the guidance of the 3D vision detector 705, and then carries the cold iron to the 2D vision detector 702 to correct the offset of the cold iron on the electromagnetic suction cup gripper 704, and corrects the deviation between the position of the cold iron and the position of the industrial robot 706. The industrial robot 706 places the cold iron on the cold iron posture correction area according to the corrected trajectory of the industrial robot 706, and the cold iron is transferred from the posture correction area to the cold iron output area. Thereafter, the industrial robot 706 or other robots can accurately pick up the cold iron and transfer it to the core making machine, accurately place it in the cold core box, and finally realize the molding of the sand core. The cold iron feeding system calibrates the cold iron posture and automatically transports it, which can directly provide cold iron to the cold core box efficiently and accurately, thereby improving the production efficiency of the sand core and improving the consistency and quality stability of the product.

[0024] Specifically, in this embodiment, the cold iron storage area is formed by the upper top surface of the storage bracket 701 erected on one side of the base 710 to reduce the occupation of the top space of the base 710.

[0025] It should be noted that the 2D vision detector 702 and the 3D vision detector 705 are both known commercial products and will not be described in detail herein.

[0026] In some embodiments of the present invention, Figure 1 As shown, the cold iron feeding system also includes a shuttle platform 709, which is movably installed on a base 710. The shuttle platform 709 can be moved to a cold iron posture correction area or a cold iron output area.

[0027] In this embodiment, the shuttle platform 709 is first moved to the cold iron posture correction area, and then the industrial robot 706 places the cold iron directly on the shuttle platform 709 according to the corrected trajectory of the industrial robot 706. Thereafter, the shuttle platform 709 moves the cold iron to the cold iron output area to ensure the stability of the cold iron position.

[0028] It should be noted that a plurality of chills can be placed on the shuttle platform 709 at one time and then moved to the chill output area in a centralized manner.

[0029] In some embodiments of the present invention, Figure 1 As shown, the chill feeding system further includes a driving member 708, which connects the shuttle platform 709 and the base 710. The driving member 708 can drive the shuttle platform 709 to reciprocate between the chill posture correction area and the chill output area.

[0030] Specifically, in this embodiment, the driving member 708 is a telescopic cylinder, the cylinder barrel of the telescopic cylinder is connected to the base 710, and the piston rod of the telescopic cylinder is connected to the shuttle platform 709. When the telescopic cylinder is extended to a certain length, the shuttle platform 709 is located in the cold iron posture correction area. When the telescopic cylinder is shortened to a certain length, the shuttle platform 709 is located in the cold iron output area.

[0031] The position of the shuttle platform 709 between the cold iron posture correction area and the cold iron output area is driven to change by the extension and contraction of the telescopic cylinder, and the structure is simple and the control accuracy is high.

[0032] In some embodiments of the present invention, Figure 1 As shown, the chill feeding system further includes a linear guide 707, which connects the shuttle platform 709 and the base 710, and guides the shuttle platform 709 to perform linear motion between the chill posture correction area and the chill output area.

[0033] The linear guide 707 can improve the linearity of the shuttle platform 709 on the base 710, and improve the position accuracy of the shuttle platform 709 when it moves to the cold iron posture correction area or the cold iron output area.

[0034] Furthermore, two linear guides 707 are installed between the shuttle platform 709 and the base 710 in parallel and at intervals.

[0035] Specifically, the linear guide 707 can adopt a structure such as a telescopic rod or a slide rail and a slider.

[0036] In some embodiments of the present invention, Figure 1 As shown, the chilled iron feeding system further includes a storage hopper 703, which is disposed on the chilled iron storage area and is used to store the chilled iron.

[0037] The storage hopper 703 can increase the amount of temporary storage of chilled iron, reduce the frequency of transporting chilled iron to the chilled iron feeding system, and improve work efficiency.

[0038] It should be noted that the chills can be directly placed in the storage hopper 703 in an unordered manner, and then the chill feeding system can complete the posture correction of the chills.

[0039] Furthermore, the edge of the storage hopper 703 is gradually lowered from the side away from the cold iron posture correction area to the side close to the cold iron posture correction area to reduce obstacles and facilitate the industrial robot 706 to pick up the cold iron from the storage hopper 703.

[0040] Furthermore, the storage hopper 703 is movably placed on the cold iron storage area, and the cold iron can be quickly replaced by moving the storage hopper 703 by a forklift.

[0041] In some embodiments of the present invention, Figure 1 As shown, the industrial robot 706 is arranged close to the cold iron storage area and the cold iron posture correction area to reduce the activity radius of the industrial robot 706 and improve work efficiency.

[0042] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
