Description

Technical Field

[0001] This utility model relates to a punch press, specifically a punch press with a multi-station structure. Background Technology

[0002] In the stamping production process of hardware parts, due to the complexity of the stamping process and the large variations in the product shape, time connection issues inevitably arise during the transfer of products from one mold to the next. In mass production, the time loss caused by each robotic arm handling connection increases with the increase in product output, thereby increasing the manufacturing cost of the product.

[0003] In the stamping production of metal parts, due to the mismatch between orders and production capacity, there may be situations where large-tonnage machines are idle while small-tonnage machines are running. A single small-tonnage machine can only be equipped with one set of molds for production, and one product requires multiple stamping presses and multiple sets of molds, resulting in low equipment efficiency. Conversely, a single large-tonnage machine can be equipped with multiple sets of molds, and the same number of molds can be produced using fewer machine tools. From an energy efficiency perspective, the production cost using large-tonnage, multi-station machine tools is lower than the production method using small-tonnage machines with one set of molds per machine. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-station structure for a punch press, which assembles multiple station structures on the same large-tonnage punch press. Multiple sets of molds can be processed simultaneously using a single large-tonnage punch press, thus improving processing efficiency. A simple robotic arm component is used to handle product handling, enabling the robotic arm component to transfer products between multiple sets of molds in a single operation, reducing product turnover times and turnover time, thereby helping to reduce defective products.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-station structure for a punch press, comprising a robotic arm assembly and multiple suction cup arm assemblies equally spaced on the robotic arm assembly. The robotic arm assembly includes a vertical motion module and a horizontal motion module disposed on the vertical motion module. The vertical motion module and the horizontal motion module are connected by a connecting block. A fixed slide rail is fixed on the upper surface of the horizontal motion module, and an arm connecting plate is disposed at the end of the horizontal motion module away from the vertical motion module. A reinforcing plate is disposed on the fixed slide rail, and the end of the reinforcing plate away from the fixed slide rail is fixedly connected to the arm connecting plate. The suction cup arm assembly includes a connecting corner block and an extension arm. The connecting corner block is fixed to the end of the arm connecting plate away from the horizontal motion module. A suction cup is installed below the extension arm. The mold fixing assembly includes a protrusion and multiple positioning corner posts disposed on the upper surface of the protrusion. Product stations are disposed between the multiple positioning corner posts.

[0006] Preferably, there are two vertical motion modules, which are parallel to each other and symmetrical about the two ends of the horizontal motion module.

[0007] Preferably, there are two reinforcing plates, and the two reinforcing plates are symmetrical about the two ends of the arm connecting plate.

[0008] Preferably, the horizontal motion module is provided with movable holes that extend through its upper and lower sides, and two U-shaped slides are provided between the horizontal motion module and the arm connecting plate. The slides are slidably disposed in the movable holes, and both ends of the slides are fixedly connected to the arm connecting plate.

[0009] Preferably, a strip hole is provided at the end of the arm connecting plate away from the horizontal motion module, and the connecting corner block is slidably disposed in the strip hole, so that the connecting corner block can slide in the strip hole to adjust its own position, so as to change the spacing value of the two sets of adjacent suction cup arm assemblies. In actual use, the same spacing value needs to be maintained between each two sets of adjacent suction cup arm assemblies.

[0010] Preferably, a groove is provided on the lower end face of the extended arm, and the suction cup is slidably disposed in the groove, so that the suction cup can slide in the groove, thereby changing the position of the product it adsorbs.

[0011] Preferably, the mold fixing assembly also includes a base plate, and multiple protrusions are provided, with the multiple protrusions being distributed at equal intervals along the horizontal direction, and all the multiple protrusions being fixed to the upper end surface of the base plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model assembles multiple workstation structures onto the same large-tonnage punch press, allowing multiple sets of molds to be processed simultaneously on a single large-tonnage punch press, thus improving processing efficiency. When there is no available large-tonnage punch press, a small-tonnage punch press can be used to install one set of molds for production. This only involves changing the mold installation method, not changing the mold structure itself. It is a flexible production process that can be determined according to the actual site conditions, which is conducive to reducing production costs.

[0014] 2. Use large-tonnage punch presses for stamping manufacturing of small and medium-sized products, and use simple robotic arm components for product handling. The robotic arm components can complete the transfer of products between multiple sets of molds in one operation, reducing the number of product turnovers and turnover time, thereby helping to reduce defective products.

Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0023] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. 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.

[0024] Please see Figure 1 This utility model provides an embodiment of a punch press with a multi-station structure, including a robot arm assembly 1 and multiple suction cup arm assemblies 2 arranged at equal intervals on the robot arm assembly 1. The number of suction cup arm assemblies 2 installed on the production site can be adjusted according to the number of mold sets. A mold fixing assembly 3 is provided below the suction cup arm assembly 2. The robot arm assembly 1 is a two-axis handling robot arm assembly. The robot arm assembly 1 can be directly installed on the punch press without the need for additional frame manufacturing. Through compact design, the space occupation can be reduced and the development and manufacturing costs of the equipment can be reduced.

[0025] Please see Figure 2The robotic arm assembly 1 includes a vertical motion module 11 and a horizontal motion module 12 mounted on the vertical motion module 11. Two vertical motion modules 11 are provided, and the two vertical motion modules 11 are parallel to each other and symmetrical about the two ends of the horizontal motion module 12. The vertical motion module 11 and the horizontal motion module 12 are connected by a connecting block 13. A fixed slide rail 14 is fixed to the upper end face of the horizontal motion module 12, and an arm connecting plate 16 is provided at the end of the horizontal motion module 12 away from the vertical motion module 11. A reinforcing plate 15 is provided on the fixed slide rail 14. The end of the reinforcing plate 15 away from the fixed slide rail 14 is fixedly connected to the arm connecting plate 16. There are two reinforcing plates 15, and the two reinforcing plates 15 are symmetrical about the two ends of the arm connecting plate 16. The suction cup arm assembly 2 includes a connecting corner block 21 and an extension arm 22. The connecting corner block 21 is fixed to the end of the arm connecting plate 16 away from the horizontal motion module 12. The mold fixing assembly 3 includes a base plate 31, a protruding platform 32, and multiple positioning corner posts 33 provided on the upper surface of the protruding platform 32. The protruding platform 32 has multiple positioning corner posts. Multiple protrusions 32 are evenly spaced along the horizontal direction and are fixed to the upper surface of the base plate 31. Product stations 34 are set between multiple positioning corner posts 33. In addition, the mold fixing component 3 is suitable for small and medium-sized product molds (product size within 500mm x 500mm). Small and medium-sized product molds produced using this process can use the original molds without modification. Only a two-axis handling robot can be installed on the large-tonnage punch press for product handling. In terms of mold installation, the product spacing between each set of small and medium-sized product molds needs to be consistent to facilitate product handling by the robot component 1. The number of product stations 34 represents the number of sets of small and medium-sized product molds to be processed. Each set of molds occupies one product station 34, and each product station 34 corresponds to one suction cup arm component 2. When the equipment is running, when the punch press is at its highest point, the suction cup arm component 2 begins to handle the product. After handling the product to the next corresponding process, the suction cup arm component 2 stops in the gap between itself and the product station 34, waiting for the punch press to finish one pass before handling the product again.

[0026] Please see Figures 3 to 4The horizontal motion module 12 has movable holes 121 that pass through its upper and lower sides. There are two U-shaped slides 17 between the horizontal motion module 12 and the arm connecting plate 16. The slides 17 are slidably disposed in the movable holes 121, and both ends of the slides 17 are fixedly connected to the arm connecting plate 16. A strip hole 161 is provided at the end of the arm connecting plate 16 away from the horizontal motion module 12. The connecting corner block 21 is slidably disposed in the strip hole 161, so that the connecting corner block 21 can slide in the strip hole 161 to adjust its own position, so as to change the spacing value of the two sets of adjacent suction cup arm assemblies 2. In actual use, the same spacing value needs to be maintained between each two sets of adjacent suction cup arm assemblies 2.

[0027] Please see Figure 5 A suction cup 23 is installed below the extension arm 22, and a groove 221 is provided on the lower end face of the extension arm 22. The suction cup 23 is slidably disposed in the groove 221, so that the suction cup 23 can slide in the groove 221, thereby changing the position of the product it adsorbs.

[0028] Please refer to the following: Figures 1 to 5 This utility model uses a simple robotic arm component 1 to transport products. By installing multiple sets of molds for small and medium-sized products on a large-tonnage punch press, multiple products can be formed in each punching. When used in conjunction with an automatic feeder to form a production line, the production cycle of small and medium-sized stamped products can be greatly improved, the input of manual labor can be reduced, and the safety risks can be reduced.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
