Description

Technical Field

[0001] The utility model belongs to the technical field of bending machines, in particular to a bending machine blade assembly. Background Art

[0002] A bending machine is a machine specially used for bending thin plates. It uses the strong pressure provided by the power system to cause the upper and lower molds to move relative to each other, thereby exerting a strong force on the metal sheet placed between the two, causing it to be precisely bent and deformed according to the pre-set angle and shape; bending machines are widely used in the field of metal processing, such as manufacturing, construction and other industries, and are mainly used to produce metal parts of various shapes and sizes. Its notable features include easy operation, high precision, outstanding efficiency, etc., and it can flexibly adjust key parameters such as bending angle, depth and speed according to different production needs, so as to fully meet diverse production requirements. For example, bending machines play a vital role in many aspects such as furniture manufacturing, electrical housing production, and automotive parts processing;

[0003] However, when the bending machine performs the bending operation, the upper pressing knife needs to be reasonably arranged according to the bending length of the workpiece to avoid defects such as warping and poor bending accuracy of the workpiece due to the workpiece not being pressed by the full length during the bending process. In the prior art, for example, the mold knife device and method of the fully automatic bending equipment proposed by the Chinese patent with the announcement number "CN112275851B" are intended to solve the problem of the upper pressing knife corresponding to the bending length of the workpiece, but the solution is to evenly distribute the changed gap between each upper pressing knife. This adjustment mode is relatively complicated, requiring the operator to perform cumbersome calculations and adjustments, and there is a gap between the parallel upper pressing knives. Under the huge pressure generated by the bending, the upper pressing knife installed on the guide rail is prone to twisting or swinging due to the assembly gap. On the whole, this not only requires improving the production and assembly accuracy of the upper pressing knife, but also increases the production cost invisibly, and also adds the factor of unstable quality to a certain extent.

[0023] refer to Figure 1-Figure 3 The transverse drive assembly 5 includes a fixed seat 51 and a slide rail 52. The slide rail 52 is fixedly installed on the side of the front of the mounting plate 2 away from the blade 36. A second motor 53 is fixedly installed on the inner side of the fixed seat 51. The output end of the second motor 53 passes through the fixed seat 51 and is fixedly installed with a second active pulley 54. A second transmission pulley 55 is fixedly installed on the side of the fixed seat 51 away from the second motor 53. The end of the second transmission pulley 55 close to the fixed seat 51 is rotatably connected with a screw rod 57. The end of the screw rod 57 passes through the fixed seat 51. The outer surface of the slide rail 52 is slidably connected with a slide frame 56. The slide seat 31 is fixedly installed on the front of the slide frame 56. The screw rod 57 and the slide seat 31 are threadedly connected. The overall cross-sectional shape of the inner side of the slide frame 56 is a convex shape. The overall cross-sectional shape of the slide rail 52 is an I-shaped setting. The slide rail 52 is fixedly installed on the front of the mounting plate 2. The sliding of the slide frame 56 provides a stable track to ensure smooth and accurate sliding. The second motor 53 on the inner side of the fixed seat 51 provides power.

[0024] Principle and advantages of use: By setting the transverse driving component 5, the device can start the second motor 53 to operate when adjusting. When the second motor 53 works, it drives the second active pulley 54 to rotate, and the rotation of the second active pulley 54 can assist in driving the second transmission pulley 55 to rotate accordingly. With the rotation of the second transmission pulley 55, the screw rod 57 can be further driven to rotate. Since the slide seat 31 and the screw rod 57 are threadedly connected, during the rotation of the screw rod 57, the slide frame 56 at the bottom of the slide seat 31 can be driven to slide smoothly on the slide rail 52. By adjusting the transverse sliding of the slide frame 56, the entire angle adjustment component 3 and the blade 36 inside it can be assisted to achieve transverse displacement. In this way, the device as a whole is more convenient when the blade 36 is adjusted transversely, which greatly improves the overall adjustment adaptability and ease of use of the device.

[0025] By setting the transverse drive component 5, during the use of the device, after the position adjustment is completed by the transverse drive component 5, the first motor 32 can be started to run, and the first motor 32 starts to drive the first driving wheel to rotate, and with the help of the transmission effect of the transmission belt, the first driven wheel can be driven to rotate synchronously. Through the rotation of the first driven wheel, the shaft body 35 can be driven to rotate. A blade 36 is installed on the shaft body 35. As the shaft body 35 rotates, the blade 36 can be driven to rotate synchronously. The rotation of the blade 36 can change its own angle. By adjusting the lateral position of the blade 36 and changing the longitudinal angle of the blade 36, it can flexibly adapt to the processing requirements of the bending machine. In addition, the entire adjustment structure only uses the motor and the pulley to cooperate with each other to achieve adjustment. The overall adjustment structure is relatively simple and the operation is stable and reliable.
