Description

Technical Field

[0001] The utility model relates to the technical field of molds, and particularly relates to a punching structure for changing the direction of acting force. Background Art

[0002] The mold punching structure is an indispensable technology in industrial production, which involves multiple aspects such as the design and manufacturing of molds, and the planning and implementation of punching processes. The main objective of the mold punching structure is to efficiently and precisely cut materials into predetermined shapes and sizes through precise mold structures and reasonable punching processes. This technology is widely used in fields such as automobiles, electronics, household appliances, and hardware, and is of great significance for improving product accuracy, reducing production costs, and enhancing production efficiency; during the production punching process of molds, general punching presses perform punching vertically downward, and for some special parts, the punching press needs to perform upward punching, and most upward punching operations are achieved by using oil cylinders.

[0003] The existing methods for the oil cylinder to provide upward punching force have problems such as large volume of the oil cylinder structure, the need for an additional power source, and high costs. When there are these special factors or in special scenarios, it is impossible to use the oil cylinder to achieve upward punching. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a punching structure for changing the direction of acting force. When the punching press closes the mold downward, it presses the transmission rod, the transmission rod presses the rocker, and the rocker pushes the movable plate, so that the cutting edge connected to the movable plate moves upward to complete cutting, converting the downward force into an upward force, changing the direction of the acting force, optimizing the use of the oil cylinder to provide additional acting force, and reducing the production cost.

[0005] The utility model is realized through the following technical solutions:

[0006] A punching structure for changing the direction of acting force includes a template, a bracket, a cutting edge. The bracket is fixedly connected to the punching press base, the template is fixedly connected to the bracket, the cutting edge passes through the through hole provided in the template and is movably connected to the template. A guide seat is fixedly connected to the template, the guide seat and the through hole provided in the template are movably connected with a transmission rod. A rocker base is fixedly connected to the bottom of the template, a fulcrum member is fixedly connected to the bottom of the rocker base, the fulcrum member is rotatably connected with a rocker, the rocker is movably connected with a movable plate, and the cutting edge is fixedly connected to the top surface of the movable plate.

[0007] Further, the guide seat is fixedly connected to the top surface of the template near both ends.

[0008] Further, a U-shaped groove is formed in the transmission rod, and a bolt fixedly connected to the guide seat passes through the U-shaped groove.

[0009] Further, the seesaw base is fixedly connected to the bottom surface of the template on the inner side closer to the transmission rod.

[0010] Further, the fulcrum member is rotatably connected to the seesaw through a pin.

[0011] Further, one end top of the seesaw abuts against the bottom of the transmission rod, and the other end top abuts against the buffer members connected to both ends of the bottom of the movable plate.

[0012] Further, guide posts are fixedly connected to the top surface of the movable plate between the cutting edges, and the guide posts are slidably fitted with the sliding sleeves connected to the bottom surface of the template.

[0013] Further, grooves are provided on the top surfaces of both ends of the movable plate and the opposite bottom surface of the template, and springs are movably connected to the grooves.

[0014] Compared with the prior art, the utility model has the following obvious advantages:

[0015] 1. When the punching press closes the die downward, the transmission rod is pressed, the transmission rod presses the seesaw, and the seesaw pushes the movable plate, so that the cutting edges connected to the movable plate move upward to complete cutting, converting the downward force into an upward force, changing the direction of the acting force, optimizing the use of an oil cylinder to provide an additional acting force, and reducing the production cost.

[0016] 2. Since a spring is connected between the movable plate and the template in the utility model, when the punching press opens the die upward, the spring compressed during die closing releases pressure to push the movable plate to reset, the movable plate pushes the seesaw, and the seesaw pushes the transmission rod to reset, waiting for the next action, and the punching structure automatically resets without the need to provide an additional acting force and a power source.

[0017] 3. Since guide posts are movably connected between the movable plate and the template in the utility model, the relative position between the template and the movable plate in the vertical direction can be further limited, ensuring the stability and accuracy during punching.

[0022] The present utility model will be introduced in detail below in conjunction with the accompanying drawings.

[0023] As Figure 1 and Figure 2 shown, the present utility model provides a punching structure for changing the direction of the acting force, including a template 3, a bracket 4, a guide seat 2, a transmission rod 1, a rocker 6, a rocker base 10, a movable plate 7, and a cutting edge 13; in this embodiment, the bracket 4 is fixedly connected to the punching machine base, the template 3 is fixedly connected to the bracket 4, the guide seat 2 is fixedly connected to the top surface of the template 3 near both ends, the transmission rod 1 passes through the through hole provided in the guide seat 2 and the template 3 below it, a U-shaped groove 11 is formed in the transmission rod 1, and a bolt fixedly connected to the guide seat 2 passes through the U-shaped groove 11 and is movably connected to the transmission rod 1; the rocker base 10 is fixedly connected to the bottom surface of the template 3 near the transmission rod 1, a fulcrum member 5 is fixedly connected to the bottom of the rocker base 10, the rocker 6 is rotatably connected to the fulcrum member 5 through a pin, one end of the rocker 6 abuts against the bottom of the transmission rod 1, and the other end abuts against a buffer member 9 connected to both ends of the bottom of the movable plate 7, the cutting edge 13 is fixedly connected to the top surface of the movable plate 7, the cutting edge 13 passes through the through hole provided in the template 3 and is movably connected to the template 3, a guide post 8 is fixedly connected to the top surface of the movable plate 7 between the cutting edges 13, the guide post 8 is slidably fitted with a sliding sleeve connected to the bottom surface of the template 3, grooves are provided on the top surfaces of both ends of the movable plate 7 and on the bottom surface of the opposite template 3, and a spring 12 is movably connected to the grooves.

[0024] When the present utility model is in use, the punching machine closes the mold downward, pressing the transmission rod 1 protruding from the guide seat 2 on the top surface of the template 3 near both ends. The transmission rod 1 moves downward and presses one end of the rocker 6. Supported by the rocker base 10 and the fulcrum member 5 fixedly connected to the bottom of the rocker base, the other end of the rocker 6 tilts upward. The two rockers 6 push the movable plate 7 to move upward. The guide post 8 fixedly connected to the top surface of the movable plate 7 and slidably connected to the template 3 guides the upward movement of the movable plate 7 to prevent the movement of the movable plate 7 from deviating. At the same time, the spring 12 movably connected to the groove between the top surface of the movable plate 7 and the bottom surface of the template 3 is compressed. The upward movement of the movable plate 7 pushes the cutting edge 13 fixedly connected to the top surface of the movable plate 7 to move upward to complete the cutting of the product.

[0025] When the punching machine opens the mold upward, the acting force pressing the transmission rod 1 disappears. The spring 12 movably connected to the groove between the top surface of the movable plate 7 and the bottom surface of the template 3 releases the pressure and rebounds from the compressed state, pushing the movable plate 7 to move downward and reset. The movable plate 7 pushes one end of the rocker 6, and the other end movably connected to the transmission rod 1 tilts upward, pushing the transmission rod 1 to reset. The bolt fixedly connected to the guide seat 2 passes through the U-shaped groove 11 on the transmission rod 1 to limit the transmission rod 1, so that the transmission rod 1 can slide in the through hole but cannot escape. After the transmission rod 1 is reset, the punching structure waits for the next action.
