Description

Technical Field

[0001] The invention relates to the technical field of U-bolt production, in particular to a punching machine for producing U-bolts. Background Art

[0002] The stamping machine for U-bolt production is a stamping machine specially used for producing U-bolts. This type of machine generally needs to have high precision and efficiency, and can quickly and efficiently stamp metal sheets or steel pipes into precise U-bolts.

[0003] In the process of using the existing technology, it is difficult to simulate the pressure distribution in the stamping process and simulate different types of stamping loads without damaging the mechanical equipment, which makes it difficult for the staff to have a more comprehensive understanding of the performance of the machine under actual working conditions; when the existing technology uses the airbag for stamping simulation, it is difficult to accurately control the size and shape of the airbag, resulting in the failure to verify and optimize the stamping parameters in the simulation stage, increasing the problems in actual production and reducing production efficiency; when some equipment is simulating, it is difficult to pre-treat the mold at the same time, resulting in greater friction between the mold and the punch, causing excessive wear of the punch, and increasing the adhesion phenomenon on the mold surface, reducing the life of the punch;

[0004] Finally: During the use of stamping machinery for the production of U-bolts, it is difficult to ensure that the punch always remains on the predetermined trajectory during movement, which increases the probability of invalid stroke due to inaccurate path and downtime caused by abnormal reasons. At the same time, it causes workers to frequently replace or repair molds, reducing overall production efficiency, and some equipment uses gears for detection, which makes it difficult to more accurately reflect the tension state; During the use of stamping machinery for the production of U-bolts, it is difficult to adapt to U-bolts of different diameters, resulting in poor flexibility and a smaller scope of application of the stamping machinery, and some equipment achieves replacement by disassembling the punch, which increases the generation of waste and replacement time.

When the swing rod 5 drives the moving block 39 to move downward through the rotation connection with the second connecting seat 6, the moving block 39 drives the pull rope 38 to move downward, so that the length of the pull rope 38 gradually becomes longer. When the length of the pull rope 38 becomes longer, the pull rope 38 drives the winding roller 36 to rotate, and the winding roller 36 drives the ratchet 35 to rotate. During the rotation process, the ratchet 35 contacts the pawl 34 and drives it to swing. The one-way locking of the ratchet 35 provides stability under the tension of the pull rope 38. The torque output is determined to more accurately reflect the tension state of the pull rope 38, and the winding roller 36 indirectly determines the moving length of the pull rope 38 through the torque sensor 37 during the rotation process. Then the torque sensor 37 transmits the detection data to the external control system in real time, and the actual tension of the pull rope 38 is calculated through the external control system to ensure that the moving block 39 moves along a precise trajectory, reducing the probability of invalid stroke due to inaccurate path and downtime caused by abnormal reasons, while reducing the time for staff to frequently replace or trim the mold 8, thereby improving overall production efficiency.
