Description

Technical Field

[0001] This utility model belongs to the field of press technology, and specifically relates to a forging press. Background Technology

[0002] The working principle of a forging press is to use high pressure to deform metal materials, thereby achieving forging.

[0003] Chinese Patent No. CN118700621A discloses a mechanical press with adjustable stroke, including a frame, a drive device on the frame, a reciprocating component connected to the drive device, the drive device being used to drive the reciprocating component to move; a stroke adjustment component, the stroke adjustment component being used to adjust the stroke of the reciprocating component; and a belt adjustment component.

[0004] The above technical solution has the following defects: The press starts by controlling the first motor, which drives the drive pulley to rotate. The drive pulley drives the driven pulley to rotate via a synchronous belt, thereby driving the first transmission shaft to rotate. The first transmission shaft drives the input gear to rotate, which in turn drives the reduction gear to rotate. When the reduction gear rotates, it drives the crankshaft to rotate. The crankshaft drives the pressure slider to reciprocate up and down via a connecting rod, thereby stamping the material. However, during the reciprocating motion of the pressure slider, the balance is easily affected by errors caused by excessive load or long-term wear, which in turn has an adverse effect on stability and stamping accuracy.

Detailed Implementation

[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0021] Example 1:

[0022] A forging press, such as Figures 1 to 2 As shown, the device includes a frame 1, a drive assembly 2 mounted on the frame 1, a crankshaft 3 rotatably mounted on the frame 1, a pressure block 4 slidably mounted on the frame 1, and a slide rail that slides with the pressure block 4 on the frame 1. The slide rail is arranged vertically. The crankshaft 3 and the pressure block 4 are connected by a connecting rod 5. The drive assembly 2 is used to drive the crankshaft 3 to rotate, so that the crankshaft 3 drives the pressure block 4 to reciprocate in the vertical direction through the connecting rod 5.

[0023] The drive assembly 2 includes a rotary drive source 21, a rotating shaft 22, a first gear 23, and a second gear 24. The rotary drive source 21 is mounted on the frame 1. The rotary drive source 21 is preferably a motor. Alternatively, other drive sources with rotational functions can be used. The rotating shaft 22 is rotatably mounted on the frame 1. The output end of the rotary drive source 21 is connected to the rotating shaft 22 via a transmission belt. Specifically, in this embodiment, a drive pulley is coaxially mounted on the output end of the rotary drive source 21, and a driven pulley is coaxially mounted on the rotating shaft 22. The drive pulley and the driven pulley are connected via a transmission belt. The first gear 23 is coaxially mounted with the rotating shaft 22, and the second gear 24 is coaxially mounted with the crankshaft 3. The first gear 23 and the second gear 24 mesh with each other.

[0024] It should be noted that the rotary drive source 21 drives the active pulley to rotate, the active pulley drives the driven pulley to rotate through the transmission belt, the driven pulley drives the rotating shaft 22 to rotate, the rotating shaft 22 drives the gear 1 23 to rotate, the gear 1 23 drives the gear 2 24 to rotate, the gear 2 24 drives the crankshaft 3 to rotate, and the crankshaft 3 drives the pressure block 4 to reciprocate in the vertical direction through the connecting rod 5.

[0025] The frame 1 is equipped with a balancing device 6 for keeping the pressure block 4 balanced. The balancing device 6 includes at least two balancing cylinders 61 and at least two connecting rods 62. The output ends of the two balancing cylinders 61 are respectively connected to the corresponding connecting rods 62. The two connecting rods 62 are respectively connected to both sides of the pressure block 4. The two balancing cylinders 61 can generate different magnitudes of force. The force is transmitted to the pressure block 4 through the corresponding connecting rods 62 by the two balancing cylinders 61, ensuring that the pressure block 4 always remains balanced and stable, and avoiding the impact on stamping accuracy due to the imbalance of the pressure block 4.

[0026] A controller 7 is installed on the frame 1. The controller 7 is used to control the drive assembly 2. The controller 7 is electrically connected to the rotary drive source 21. The controller 7 is used to control the balancing device 6. The controller 7 is electrically connected to the balancing cylinder 61.

[0027] The pressure block 4 is provided with a limit rod 8, and the frame 1 is provided with mounting rods 12 on both sides. Each mounting rod 12 is equipped with a balance limiter. The two balance limiters are used to limit the two ends of the limit rod 8. The balance limiter includes a bolt 9, which is threaded to the mounting rod 12. The end of the bolt 9 can abut against the upper surface of the balance limiter 8. By limiting the balance limiter 8 with the bolt 9, the pressure block 4 is limited. It should be noted that by rotating the bolt 9 to adjust its position, the distance between the bolt 9 and the balance limiter 8 can be changed, thereby limiting the pressure block 4 at different positions.

[0028] It should be noted that different molds are required for different forgings. The bottom of the pressure block 4 is provided with a guide groove 10. The structure of the mold is adapted to the guide groove 10. The mold is guided by the guide groove 10, making the mold assembly and disassembly more convenient and quick.

[0029] Furthermore, the cross-section of the guide groove 10 is inverted T-shaped, which can effectively support the mold to slide along the groove, making the mold assembly and disassembly more convenient and quick.

[0030] The bottom of the frame 1 has several receiving slots 11 for accommodating counterweights, which are located at the bottom corners of the frame 1. By installing the counterweights in the receiving slots 11, the stability of the press is further enhanced.

[0031] Example 2:

[0032] The difference between Example 2 and Example 1 is that, as Figure 3As shown, the balance limiting component includes a bushing 13 and a spring 15. The bushing 13 is disposed on the lower surface of the mounting rod 12, and the spring 15 is disposed inside the bushing 13 and connected to the mounting rod 12. A shaft 14 is disposed on the limiting rod 8, and the shaft 14 is slidably disposed inside the bushing 13. The sliding of the shaft 14 can cooperate with the mounting rod 12 to compress the spring 15. The bushing 13 and the shaft 14 cooperate to guide the movement, further improving the stability of the pressure block 4 during movement. The elastic force of the spring 15 also reduces vibration.

[0033] The specific embodiments described herein are merely illustrative examples of the spirit of this utility model; those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or adopt similar methods to replace them, but without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
