Description

Technical Field

[0001] This utility model belongs to the field of transfer and conveying technology, and in particular relates to a multi-unit self-linking high-speed lifting and transfer device for a stamping production line. Background Technology

[0002] A stamping production line is a highly automated assembly line specifically designed for "metal molding". Its core task is to transform flat metal sheets into parts of the desired three-dimensional shape through a series of continuous stamping actions, such as car doors, seats, hoods, or other product parts in the field of integrated sheet metal structural frames.

[0003] In existing technologies, as the manufacturing industry continues to demand higher production efficiency, product quality, and automation levels, the traditional stamping production line operation mode has gradually exposed many problems that urgently need to be solved. Most small and medium-sized stamping production lines still rely on manual material transfer operations. That is, the raw materials to be molded are placed into the mold structure manually, and after a single molding is completed, the product is removed from the mold structure manually and transferred to the next process or subsequent processing equipment. This manual material transfer method not only requires a large investment of labor costs, but is also limited by the speed, energy, and standardization of manual operation, resulting in extremely low material transfer efficiency, which is difficult to meet the needs of large-scale, high-speed production. At the same time, during the process of grabbing and handling products, manual operation errors can easily lead to product collisions and scratches, or the placement deviation can affect the subsequent molding accuracy, which greatly increases the product damage rate and defect rate. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned technical problems by providing a multi-unit self-linking high-speed lifting and shifting transfer device for a stamping production line.

[0005] A multi-unit self-linking high-speed lifting and shifting transfer device for a stamping production line includes: a die structure, wherein a product transfer structure is provided on the outer periphery of the die structure; The product transfer structure includes a first gantry and a second gantry respectively set on both sides of the molding structure.

Two clamping arms are also provided between the first gantry and the second gantry. The two ends of the two clamping arms are respectively connected to the corresponding displacement sliders. The two clamping arms are provided with clamping finger rod devices for clamping the product and moving the product. A conveying device is provided on one side of the molding structure to move the product after molding to the next process.

[0019] Reference Figures 1-3 A multi-unit self-linking high-speed lifting and shifting transfer device for a stamping production line includes: a die structure 1, wherein a product transfer structure is provided on the outer periphery of the die structure 1; The product transfer structure includes a first gantry 2 and a second gantry 3 respectively arranged on both sides of the molding structure 1. The first gantry 2 and the second gantry 3 are each provided with two sets of clamping and releasing devices 4. The clamping and releasing devices 4 are each provided with two sets of vertical lifting and lowering devices 6. The driving end of the vertical lifting and lowering device 6 is provided with a lifting and lowering slider 7. The lifting and lowering slider 7 is provided with two sets of displacement sliders 8. Two clamping arms 10 are also provided between the first gantry 2 and the second gantry 3. The two ends of the two clamping arms 10 are respectively connected to the corresponding shifting sliders 8. The two clamping arms 10 are provided with clamping finger rod devices for clamping the product and moving the product. A transport device 9 is provided on one side of the molding structure 1, which is used to move the product after molding by the molding structure 1 to the next process.

[0020] In use, this device forms a stable material transfer support frame by symmetrically arranging the first gantry 2 and the second gantry 3. Two sets of clamping and releasing devices 4, together with multiple sets of vertical lifting and lowering devices 6 and shifting sliders 8, form a continuous action of clamping-lifting-shifting-lowering, solving the problems of fragmented action and delayed connection in traditional transfer devices. The connection design between the clamping long arm 10 and the shifting slider 8 improves the versatility of the device. The finger clamping device accurately clamps the product while avoiding product damage and low efficiency caused by manual transfer. The end transport device 9 directly connects to the next process, eliminating intermediate buffer links in product transfer, improving the continuous operation efficiency of the stamping production line, and reducing the cost of manual intervention.

[0021] In the example of this application, the clamping and releasing device 4, the vertical lifting and lowering device 6, and the clamping long arm 10 are all electric slide rails.

[0022] As a preferred example of this utility model, electric slide rails have the advantages of faster response speed and higher motion accuracy compared to traditional pneumatic or hydraulic drive methods, which can adapt the clamping, lifting, and shifting actions to the high-speed operation requirements of stamping production lines.

[0023] In use, the clamping and releasing device 4 drives the corresponding vertical lifting and lowering device 6 and the clamping long arm 10 to separate to both sides. Then, the vertical lifting and lowering device 6 drives the clamping long arm 10 to move down. Then, the clamping and releasing device 4 drives the corresponding vertical lifting and lowering device 6 and the clamping long arm 10 to move closer together, so that the finger clamping device is located below the product. Then, the vertical lifting and lowering device 6 drives the clamping long arm 10 to move up, lifting the product. Then, the clamping long arm 10 drives the product to move. When it moves to the correct position, the vertical lifting and lowering device 6 moves down to separate the finger clamping device from the product. Finally, the clamping and releasing device 4 moves the corresponding vertical lifting and lowering device 6 and the clamping long arm 10 to a position that will not interfere with the product molding.

[0024] In the example of this application, the molding structure 1 includes a lower worktable 11, on which a plurality of lower molds 12 are provided. An upper worktable 13 is installed above the lower worktable 11 via a lifting drive structure. A plurality of upper molds 14 are provided below the upper worktable 13. The positions of the plurality of lower molds 12 and the plurality of upper molds 14 correspond to each other.

[0025] As a preferred example of this utility model, the corresponding arrangement of the lower worktable 11 and the upper worktable 13, along with the matching lower mold 12 and upper mold 14, ensures the precise alignment of the lower mold 12 and upper mold 14 during the molding process, effectively reducing the product scrap rate caused by mold misalignment. The design of the lifting drive structure driving the upper worktable 13 can adjust the mold closing pressure and stroke according to the molding requirements of different products, adapting to various stamping scenarios from thin plates to thick components, improving the versatility of the molding structure 1. The parallel arrangement design of multiple sets of molds can be linked with the multiple clamping units of the product transfer structure to realize the synchronous stamping and transfer of multiple products, greatly improving the production capacity of a single molding structure 1, making the device more suitable for large-scale batch production needs.

[0026] When using the clamping and releasing device 4, the vertical lifting and lowering device 6, and the clamping long arm 10 to transfer products on the lower mold 12, the single-step movement rule is followed: products can only be transferred from the previous lower mold 12 to the next adjacent lower mold 12, and the displacement distance is equal to the spacing of one lower mold 12.

[0027] The upper mold 14 and the lower mold 12 can be set in 3 to 7 sets depending on the product. When the upper mold 14 and the lower mold 12 are added, the clamping arm 10 of appropriate length should be replaced.

[0028] In the example of this application, the finger clamping device includes a plurality of finger clamping seats 15 disposed on a clamping long arm 10, a finger clamping rod 16 disposed on one side of each of the plurality of finger clamping seats 15, and a clamping head 17 disposed on one side of each finger clamping rod 16.

[0029] As a preferred example of this utility model, the fixed arrangement of the finger holder 15 on the clamping arm 10 provides a stable mounting base for the finger clamping rod 16, avoiding the shaking and displacement of the finger clamping components during transportation; the integrated design of the finger clamping rod 16 and the chuck 17 enables the clamping force to be accurately transmitted to the product, while the chuck 17 can be adapted to the product shape to increase the contact area with the product and reduce scratches on the product surface caused by excessive local pressure.

[0030] In the example of this application, every two clamps 17 constitute a set of clamping units, and the clamping units on the clamping arm 10 are in a one-to-one correspondence with the clamping units on the other side of the clamping arm 10.

[0031] As a preferred example of this utility model, the clamping unit formed by two chucks 17 can provide symmetrical clamping force, avoiding problems such as uneven force on the product and center of gravity shift caused by clamping with a single chuck 17, ensuring the stability of the product posture during transportation, especially suitable for irregularly shaped or center of gravity shifted stamping products. The one-to-one arrangement of clamping units on the clamping arms 10 on both sides makes the clamping force on both sides of the product completely symmetrical, further improving the transportation positioning accuracy.

[0032] In the example of this application, the finger clamp 16 and the clamp 17 may be type I, type L and type S, depending on the structure of the molded product. Here, we describe it as type I.

[0033] As a preferred example of this utility model, for different molded products (such as flat, bent, and irregularly shaped products), different shaped clamping fingers 16 and clamps 17, such as I-shaped, L-shaped, and S-shaped, can be replaced without modifying the main structure such as the clamping arm 10, thus shortening the product changeover time and adapting to the production needs of small batches and multiple varieties.

[0034] In the example of this application, the transport device 9 is a conveyor belt transport device 9.

[0035] As a preferred example of this utility model, the conveyor belt transportation has the advantages of continuous conveying and adjustable conveying speed, which can be precisely matched with the stamping rhythm of the die structure 1 and the transfer rhythm of the material transfer structure, thus avoiding the accumulation of products during the transfer process.

[0036] In the example of this application, the upper worktable 13 and the lower worktable 11, as well as the upper mold 14 and the lower mold 12, are all arranged between the clamping units composed of two sets of clamping long arms 10 and their components.

[0037] As a preferred example of this utility model, the clamping unit clamps the product inside the mold from both sides, shortening the extension and retraction stroke of the clamping finger rod 16, making the response speed of the clamping-lifting action faster and improving the overall transfer efficiency; the layout of clamping on both sides can make the clamping force closer to the center of gravity of the product, improving the clamping stability.

[0038] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
