Description

Technical Field

[0001] This utility model belongs to the field of material handling technology in mold processing, and particularly relates to a material handling mechanism for adjusting the position of the in-mold transfer station in a multi-station transfer process. Background Technology

[0002] Traditional stamping die equipment can only process one workpiece at a time. When processing multiple workpieces, repeated manual clamping and unloading are necessary, which is time-consuming and inefficient. Multi-station transfer stamping dies, by integrating multiple stations into a closed-loop system, enable continuous processing of multiple workpieces in a single clamping, significantly saving time and labor costs. Furthermore, this equipment ensures high precision and consistency for each workpiece across different processing steps, thereby improving product quality. Multi-station transfer stamping dies are widely used in the metal processing field, capable of simultaneously stamping multiple workpieces. Specifically, this equipment consists of a precisely moving carrier and a series of orderly arranged workstations, each equipped with specialized stamping tools or equipment capable of processing multiple workpieces sequentially. During operation, through automatic carrier transfer, workpieces move sequentially from one workstation to another, achieving a series of continuous processing steps, improving production efficiency and reducing the need for manual operation. When a traditional multi-station transfer mold produces two symmetrical parts, a certain gap must be left between the two products to meet the structural space requirements of processes such as forming, side cutting, and punching. The traditional solution is to widen the width between the two materials in the stamping process to match the width of the subsequent process, but this method leads to material waste. Utility Model Content

[0003] The purpose of this utility model is to provide a material handling mechanism for adjusting the position of the workstation in a multi-station transfer mold. It aims to solve the problem that in the traditional multi-station transfer mold, when producing two symmetrical parts, a certain gap must be left between the two products to meet the structural space requirements of processes such as forming, side cutting, and punching. The traditional solution is to widen the width between the two materials in the stamping process to match the width of the subsequent process, but this method will lead to material waste.

[0004] To achieve the above objectives, this utility model provides a material handling mechanism for adjusting the position of a multi-station transfer mold, comprising an upper mold base, a lower mold base, a punch cutter block, a die cutter block, a drive block, a material pulling slider, and a nitrogen spring. The upper and lower mold bases are arranged vertically opposite each other. The punch cutter block is located at the lower end of the upper mold base, and the die cutter block is located at the upper end of the lower mold base, with the die cutter block positioned below the punch cutter block. The punch and die cutter blocks cooperate to cut the material sheet. The material pulling slider is slidably disposed at the upper end of the lower mold base, and is located on one side of the die cutter block. The nitrogen spring is disposed at the upper end of the lower mold base, with one end abutting against the lower mold base and the other end abutting against the material pulling slider. The nitrogen spring is used to reset and drive the material pulling slider to move outwards towards the lower mold base. The drive block is disposed at the lower end of the upper mold base, and is located above the material pulling slider. The side of the material pulling slider near the drive block has a guide slope that slopes downwards towards the outer side of the mold base.

[0005] Furthermore, the punch cutter block includes two convex die blocks, and the die cutter block includes two concave die blocks. The concave die blocks are positioned below the convex die blocks, and the concave die blocks and convex die blocks cooperate with each other to cut the material sheet.

[0006] Furthermore, it also includes a stripper plate and an elastic reset member. The stripper plate is disposed between the two convex dies, and one end of the elastic reset member is connected to the upper die base, while the other end is connected to the stripper plate.

[0007] Furthermore, the lower die base is provided with a mounting groove for slidingly mounting the material pulling slider, and the mounting groove is located on one side of the die block.

[0008] Furthermore, the top surface of the material pulling slider is flush with the top surface of the die block.

[0009] The material handling mechanism for adjusting the position of a multi-station conveying mold provided in this utility model embodiment has at least one of the following technical effects: When the sheet material is transported between the upper and lower mold bases, the punch press drives the upper mold base to move towards the lower mold base. The drive block begins to contact the material pulling slider and compresses the nitrogen spring, causing the material pulling slider to reach the designated receiving position. Subsequently, the punch press continues to descend, and the sheet material separates under the action of the punch and die blocks and falls onto the material pulling slider. At this time, one punching action is completed, and the sheet material has been separated, with one end of the sheet material falling onto the material pulling slider. The nitrogen spring is in a compressed state. Then, the punch press moves upward, driving the upper mold base upward, and the drive block moves upward accordingly, beginning to separate from the material pulling slider. The nitrogen spring is no longer under force and begins to return to a free state, driving the material pulling slider to slide outward, pulling the sheet material to the designated position. Subsequently, the automatic clamping clamp conveys the sheet material to the next process. The material handling mechanism for adjusting the position of the workstation in a multi-station conveying mold provided by this utility model mainly uses a drive block to drive the material pulling slider to pull the material sheet apart by a specified distance, thereby increasing the distance between the material sheets and providing sufficient operating space for subsequent processes. Compared with the traditional multi-station conveying mold that performs mirror punching on both ends of the material sheet, this avoids material waste between the two punched material sheets.

Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0018] In one embodiment of this utility model, reference is made to Figures 1-2As shown, a material handling mechanism for adjusting the position of a multi-station transfer mold is provided, including an upper mold base 100, a lower mold base 200, a punch cutter block 300, a die cutter block 400, a drive block 500, a material pulling slider 600, and a nitrogen spring 700. The upper mold base 100 and the lower mold base 200 are arranged vertically opposite each other. The punch cutter block 300 is located at the lower end of the upper mold base 100, and the die cutter block 400 is located at the upper end of the lower mold base 200, with the die cutter block 400 located at the lower end of the punch cutter block 300. The punch cutter block 300 and the die cutter block 400 cooperate to cut the material sheet. The material pulling slider 600 is slidably disposed at the upper end of the lower mold base 200, and the material pulling slider 600 is located on one side of the die cutter block 400. The nitrogen spring 700 is disposed at the upper end of the lower mold base 200, and one end of the nitrogen spring 700 abuts against the lower mold base 200, and the other end abuts against the material pulling slider 600. The nitrogen spring 700 is used to reset and drive the material pulling slider 600 to move to the outside of the lower mold base 200. The drive block 500 is disposed at the lower end of the upper mold base 100, and the drive block 500 is located at the upper end of the material pulling slider 600. The side of the material pulling slider 600 near the drive block 500 is provided with a guide slope 610 that slopes from top to bottom to the outside of the lower mold base 200. In this embodiment, when the sheet material is transported between the upper die holder 100 and the lower die holder 200, the punch press drives the upper die holder 100 to move towards the lower die holder 200. The drive block 500 begins to contact the material pull slider 600 and compresses the nitrogen spring 700, causing the material pull slider 600 to reach the designated position for receiving the sheet material. Subsequently, the punch press continues to descend, and the sheet material separates under the action of the punch block 300 and the die block 400, falling onto the material pull slider 600. At this point, one punching action is completed, and the sheet material has been separated, with one end of the sheet material falling onto the material pull slider 600. The nitrogen spring 700 is in a compressed state. Then, the punch press moves upward, driving the upper die holder 100 upward, and the drive block 500 moves upward accordingly, beginning to separate from the material pull slider 600. The nitrogen spring 700 is no longer under force and begins to return to a free state, driving the material pull slider 600 to slide outward, pulling the sheet material to the designated position. Subsequently, the automatic clamp transfers the sheet material to the next process. The material handling mechanism for adjusting the position of the workstation in a multi-station conveying mold provided by this utility model mainly uses the drive block 500 to drive the material pulling slider 600 to pull the material sheet apart by a specified distance, thereby increasing the distance between the material sheets and providing sufficient operating space for subsequent processes. Compared with the traditional multi-station conveying mold that performs mirror punching on both ends of the material sheet, this avoids material waste between the two punched material sheets.

[0019] Specifically, see reference Figures 1-2As shown, the punch die block 300 includes two punch dies 310, and the die die block 400 includes two die dies 410. The die dies 410 are disposed below the punch dies 310, and the die dies 410 and punch dies 310 cooperate with each other to cut the material sheet. In this embodiment, the die dies 410 and punch dies 310 cooperate with each other to cut the material sheet into two symmetrical products.

[0020] Specifically, see reference Figures 1-2 As shown, it also includes a stripper plate 800 and an elastic reset member 900. The stripper plate 800 is disposed between the two punches 310. One end of the elastic reset member 900 is connected to the upper die base 100, and the other end is connected to the stripper plate 800. In this embodiment, when the punch starts to descend, the stripper plate 800 first contacts the sheet material, and then the elastic reset member 900 begins to be compressed. The stripper plate 800 provides a separating pressing force to the sheet material. As the punch continues to descend, the punch blocks 300 and the die blocks 400 punch the sheet material. One end of the sheet material is pressed by the stripper plate 800, and the other end falls onto the pull-out slider 600, preventing the position of the sheet material from changing during the punching process.

[0021] Specifically, see reference Figures 1-2 As shown, the lower mold base 200 is provided with a mounting groove 210 for slidingly mounting the material pulling slider 600. The mounting groove 210 is located on one side of the die cutter block 400. In this embodiment, the material pulling slider 600 slides within the mounting groove 210. The nitrogen spring 700 is also disposed within the mounting groove 210, with one end abutting against the lower mold base 200 and the other end abutting against the material pulling slider 600. The length of the mounting groove 210 is used to control the distance between the two products.

[0022] Specifically, see reference Figures 1-2 As shown, the top surface of the material pulling slider 600 is flush with the top surface of the die block 400. In this embodiment, the top surface of the material pulling slider 600 is flush with the top surface of the die block 400 to prevent the product position from shifting during the process of the blank being punched and falling onto the material pulling slider 600.

[0023] The rest of this embodiment is the same as that in Embodiment 1. Features not explained in this embodiment are explained using the methods in Embodiment 1, and will not be repeated here.

[0024] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
