Description

Technical Field

[0001] This utility model relates to the field of stamping feeding technology, specifically a high-speed sheet metal feeding device. Background Technology

[0002] Stamping refers to a processing method that uses a press and dies to apply external force to sheet metal, strip, tube, and profile, causing plastic deformation or separation to obtain stamped parts of the required shape and size. The blanks for stamping are mainly hot-rolled and cold-rolled steel plates and strips. When hot stamping and bending steel strips, they need to be continuously fed through steel strip coils. During processing, they need to be placed in steps on the stamping mechanism and bending mechanism, stamped first and then bent. The transmission of steel strips needs to be stopped during both stamping and bending. Therefore, automatic stamping and bending forming machines need to use sheet metal feeding devices.

[0003] However, most common sheet metal feeding devices use continuous feeding, which cannot meet the working requirements of automatic stamping and bending forming machines. Continuous feeding can easily cause steel strip accumulation, which in turn affects the forming quality of the product. In addition, the traditional manual feeding stamping method requires a lot of labor, which is not only time-consuming and laborious, but also makes it difficult to guarantee the accuracy and efficiency of feeding. Utility Model Content

A rotating connecting seat is rotatably connected to the connecting plate near the second motor.

A pressing wheel is rotatably connected to the side of the swing rod near the eccentric wheel, and the pressing wheel is in contact with the eccentric wheel. An abutment block is rotatably connected to the lower part of the side of the swing rod away from the pressing wheel.

[0007] As a further embodiment of this utility model: a connecting seat is fixedly connected to the middle edge of one side of the connecting plate; a pressing rod is slidably connected through the middle of the connecting seat; a contact rod is fixedly connected to the top of the pressing rod and contacts the abutment block; an L-shaped connecting rod is fixedly connected to one side of the top of the pressing rod, and the side of the L-shaped connecting rod away from the connecting seat passes through the connecting seat and is slidably connected; a mounting block is fixedly connected to the lower part of the side of the connecting seat away from the connecting plate; a spring is provided through the bottom of the inner cavity of the L-shaped connecting rod; a limiting slide rod is fixedly connected to the other end of the spring, and the outer wall of the limiting slide rod passes through the mounting block.

[0008] As a further embodiment of this utility model: a connecting seat two is fixedly connected to one side of the connecting plate at the upper center of the base; a lowering rod two is slidably connected through the middle of the connecting seat two; a pressing wheel three is rotatably connected through the top center of the lowering rod two, and the pressing wheel three is in contact with the eccentric wheel; an L-shaped connecting rod two is fixedly connected to one side of the top of the lowering rod two, and the side of the L-shaped connecting rod two away from the lowering rod two passes through the connecting seat two and is slidably connected; a limiting slide rod two is fixedly connected to the lower part of the side of the connecting seat two away from the connecting plate; a spring two is provided through the bottom of the inner cavity of the L-shaped connecting rod two; the other end of the spring two is fixedly connected to the limiting slide rod two, and the outer wall of the limiting slide rod two passes through the mounting block two.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, when the motor starts running, the output end drives the transmission gear to rotate. Because the transmission gear meshes with the rack, the rack slides along the inner cavity of the connecting plate and is fixed with the slide block, thereby driving the slide block and the top clamping feeding block to make reciprocating linear motion along the slide rail, realizing the basic action of intermittent feeding. With the help of the CNC program, the feeding length can be precisely adjusted, providing power for the step-by-step conveying of the steel strip, ensuring that the feeding rhythm matches the stamping and bending processes, and improving the coordination and accuracy of the overall processing. At the same time, the feeding motor determines the feeding length. In the past, the motor was mounted on the rack, and it would move with the material when feeding, which increased inertia. When running at high speed, the inertia affected the feeding accuracy.

[0015] 2. In this utility model, when motor 2 is running, the output end drives the eccentric wheel to rotate continuously. During rotation, it interacts with pressing wheel 3, and sequentially links components such as pressing rod 2 and L-connecting rod 2. The rotating connecting seat 2 stably supports the swing rod 2, allowing it to smoothly drive the extrusion plate to move. Spring 3 cooperates with the abutment rod to provide appropriate pressure buffering and flexible adjustment for the extrusion plate. These components work together to effectively assist in clamping the steel strip and can also flexibly adjust the force. Combined with other structures, it makes the feeding more accurate and stable. Compared with the prior art, it avoids the accumulation of steel strip during continuous feeding, eliminates the need for manual feeding, saves labor, improves feeding accuracy and efficiency, and ensures the product forming quality. At the same time, at any moment during feeding, one of the two clamps needs to clamp the material while the other is in a relaxed state to ensure that material squeezing does not occur.

The contact rod 22 drives the pressing rod 21 to slide along the connecting seat 20. The L-connecting rod 23, the spring 25 and the limit slide rod 26 cooperate to buffer the downward pressure. At the same time, the limit slide rod 26 pushes the pressing wheel 11 to control the clamping action of the pressing block 10.

[0028] A connecting seat 27 is fixedly connected to the middle of the upper part of the base 3 on one side of the connecting plate 2. A pressing rod 28 is slidably connected through the middle of the connecting seat 27. A pressing wheel 39 is rotatably connected through the middle of the top of the pressing rod 28 and is in contact with the eccentric wheel 15.

The top two sides of the base 3 are fixedly connected with limit rods 40, and the limit rods 40 and the buffer pads 39 abut against each other. The buffer pads 39 on both sides of the slide 5 cooperate with the limit rods 40 on the base 3 to limit the movement range of the slide 5 and reduce collision impact.

[0030] The working principle of this utility model is as follows: When the motor 6 runs, its output end drives the transmission gear 7 to rotate. Because the transmission gear 7 meshes with the rack 8, the rack 8 slides along the inner cavity of the connecting plate 2. Because the rack 8 is fixed with the slide block 5, the slide block 5 and the top clamping feeding block 9 are driven to make reciprocating linear motion along the slide rail 4 to realize the basic action of intermittent feeding. With the help of the CNC program, the feeding length can be precisely adjusted.

[0031] When motor 14 operates, its output causes eccentric wheel 15 to rotate. Eccentric wheel 15 pushes pressing wheel 18, which in turn drives swing rod 17 to swing around rotating connecting seat 16, causing contact block 19 to move. Contact block 19 touches contact rod 22, and pressing rod 21 slides down connecting seat 20. Through L-connecting rod 23, spring 25, and limit slide rod 26, pressure is applied to pressing wheel 11, causing pressing block 10 and pressing block 12 to move. This, in conjunction with pressing table 13, enables the clamping and releasing of steel strip, adapting to the material stop requirements of stamping and bending processes.

[0032] While the second motor 14 is running, the eccentric wheel 15 will also work with the third pressing wheel 29 to drive the second pressing rod 28, the second connecting rod 30 and other components. Together with the rotating connecting seat 34, the swing rod 35, the extrusion plate 36, the third spring 37 and the abutment rod 38, they will further coordinate and adjust the clamping state of the steel strip. The buffer pad 39 and the limit rod 40 play a buffering and limiting protection role in the movement of the slide 5, ensuring the stable operation of the device and ensuring accurate feeding and adaptability to the stamping and bending process.
