Description

Technical Field

[0001] The utility model relates to the technical field of continuous stamping, in particular to a manual self-locking device. Background Art

[0002] Continuous stamping is a highly efficient metalworking method. It involves continuously feeding sheet metal into a stamping die. Under the action of a press, the process sequentially completes various stamping steps, including blanking, bending, and stretching. This allows for the rapid production of large quantities of metal parts of the same shape and size. This continuous, uninterrupted stamping process offers extremely high production efficiency. Compared to single-step stamping, this significantly reduces production time and labor costs, while enabling high-speed stamping, capable of completing dozens or even hundreds of stamping operations per minute.

[0003] On a continuous stamping production line, metal sheets need to be continuously conveyed forward. The stopper can play a positioning role in the conveying direction of the sheet, ensuring that the sheet can be accurately delivered to the specific position of the stamping die every time. Through precise positioning, the position of each stamping is highly consistent, thereby ensuring the dimensional accuracy and shape accuracy of the stamped parts. If there is no positioning of the stopper, the sheet may be offset during the conveying process, resulting in large dimensional deviations of the stamped parts, affecting product quality.

[0004] The existing continuous stamping end device is in a free state under the action of the spring force. If it is a small or light product, it is easy for the block to be pushed back into place during the mold adjustment and trial mold or when producing tail materials, resulting in poor precision or mold explosion. Based on the above problems, this application proposes a manual self-locking device. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Reference Figure 1-5, a manual self-locking device includes a mounting seat 1, a mounting hole for mounting is provided on the top of the mounting seat 1, and the number of the mounting holes is four. The mounting hole is convenient for installing the mounting seat 1, and a connecting hole 2 is provided on the top of the mounting seat 1. A connecting groove 3 is provided at the bottom of the mounting seat 1. The connecting groove 3 is connected to the mounting seat 1, and a self-locking component 7 is provided inside the connecting hole 2. The self-locking component 7 includes a mounting sleeve 71 fixedly installed inside the connecting hole 2, a limiting nut 72 is fixedly provided on the surface of the mounting sleeve 71, a moving rod 73 is slidably provided inside the mounting sleeve 71, and a hand-held handle 74 is fixedly provided on the surface of the moving rod 73. A mounting circular hole 75 is provided at the bottom of the moving rod 73, and a threaded hole 76 is provided on the upper side wall of the mounting circular hole 75. The internal thread of hole 76 is provided with a screw rod 77, and the bottom of screw 77 is fixedly provided with a mounting rod 78. The mounting rod 78 is slidably arranged in the interior of the mounting circular hole 75. The bottom of the mounting rod 78 is fixedly provided with a movable circular plate 79. The movable circular plate 79 is slidably arranged in the interior of the connecting hole 2. The bottom of the movable circular plate 79 is fixedly provided with a locking block 710. The bottom of the locking block 710 is an arc surface. The radius of the locking block 710 is the same as the radius of the locking hole 5. The locking block 710 is made of metal material. The arc surface makes it easy for the locking block 710 to be inserted into the locking hole 5. The same radius ensures that the stopper 4 will not shake after being fixed, and the metal locking block 710 is not easy to deform, thereby avoiding the deformation of the locking block 710 and the inability to insert the locking hole 5. The mounting sleeve 71 is When the locking cam 710 is in the unlocked position, the locking cam 710 is in the unlocked position, and the locking cam 710 is in the unlocked position, so that the locking cam 710 can be unlocked. When the locking nut 710 is in the unlocked position, the locking nut 710 is locked and the locking nut 710 is locked.Thereby stabilizing the position of the hand-held handle 74.

[0022] When locking cam 711 is in the state of being grasped, locking cam 710 and locking cam 711 of locking cam 712 are locked, and locking cam 710 and locking cam 713 are in the state of being grasped. The locking block 710 is then removed from the locking hole 5 by the movable plate 79. At the same time, the movable plate 79 compresses the spring 711, which gives the movable plate 79 a downward thrust. The spring 711 gives the movable plate 79 a downward thrust. The mounting rod 78 gives the movable rod 73 a downward pulling force through the screw 77, so that the movable rod 73 gives the handle 74 a downward pulling force, thereby stabilizing the handle 74 on the top of the mounting sleeve 71.

[0023] In summary, the manual self-locking device locks the position of the block 4 through the self-locking component 7, so that the position of the block 4 is fixed, so that the self-locking component 7 will not push the product material belt 6 to move, and can be turned off at any time when the block 4 is not needed to work, avoiding the block pushing back the material belt event, improving production efficiency and yield rate, thereby avoiding the situation where the block is easily pushed back and misplaced during the mold adjustment and trial mold production process or when producing tail materials for small or lighter products, and avoiding the situation where poor precision or mold explosion due to the block pushing back and misplaced, thereby improving production efficiency and yield rate, and is used to solve the problems raised in the above background technology.
