Description

Technical Field

[0001] The utility model relates to the technical field of bending devices, and particularly relates to an efficient bending device for hardware locks. Background Technique

[0002] Hardware locks refer to devices made of hardware materials (such as copper, stainless steel, zinc alloy, etc.) and used to protect the safety of doors, windows, cabinets and other items. Lock bending is an important process in the manufacturing of hardware locks. Generally, it is a process of bending hardware parts according to predetermined angles and shapes through a bending device. In lock manufacturing, the bending process is often used to manufacture components such as lock tongues, lock plates, and lock bodies to meet the structural and functional requirements of the locks.

[0003] During the stamping and bending process of the parts of hardware locks, due to the action of external forces on the materials, plastic deformation occurs, and the formed parts may be tightly wrapped in the forming grooves of the molds, forming a large clamping force. This clamping force makes it difficult to take out the hardware locks after stamping is completed, affecting the bending efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to provide an efficient bending device for hardware locks to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: An efficient bending device for hardware locks, including a bending device main body, a mold, a hardware part main body, and a bending head. At the bottom end inside the bending device main body, there is a mold, and at the top end inside the bending device main body, there is a bending head. A cylinder is fixed at the top of the bending device main body, and the output end of the cylinder is connected to the bending head through a telescopic column. An forming groove is formed between the bending head and the mold, and the hardware part main body is placed inside the forming groove. At the central position inside the mold, there is a driving chamber, and a screw is arranged inside the driving chamber. A lifting sleeve is sleeved outside the screw, and a lifting plate is arranged at the top of the lifting sleeve. Ejecting rods are evenly distributed at the top end of the lifting plate. A driven gear is arranged at the bottom end of the screw, and a micro motor is arranged at the bottom end inside the driving chamber. The output end of the micro motor is provided with a driving gear meshing with the driven gear through a roller.

[0006] Preferably, guide rods are arranged on both sides at the top of the bending device main body, and both sides of the bending head are slidably sleeved with the guide rods through guide sleeves.
