Description

Technical Field

[0001] This utility model relates to the field of cold heading machines, and in particular to a flange nut cold heading machine that is safe to operate. Background Technology

[0002] A cold heading machine is a mechanical device that uses the principle of plastic deformation of metal at room temperature to apply pressure to a metal blank through a mold, causing it to flow plastically within the mold cavity, thereby shaping it into the required shape and size. It is widely used in manufacturing industries with many products such as fasteners, automotive parts, and hardware tools.

[0003] When cold heading machines produce flange nuts, they need to extrude and forge the raw materials. The flange nuts that have been extruded and forged will have a high temperature. If workers directly handle the flange nuts, they may be burned. At the same time, cold heading machines will produce a large amount of high-temperature fumes when in use. When the fumes are released, they will affect the visibility of the surrounding workers. If workers inhale them for a long time, they may also cause harm to their health.

[0004] Therefore, those skilled in the art have provided a flange and nut cold heading machine that is safe to operate, in order to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a safe flange and nut cold heading machine. The cooling module can cool down the flanges and nuts after production, and the purification module can absorb and purify the fumes generated by the cold heading process.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a safe flange nut cold heading machine, comprising a cold heading body, protective plates bolted to the middle of both sides of the cold heading body, a rotating cover hinged to the middle of the upper end of the cold heading body, a purification module fixedly mounted on the front of the upper end of the cold heading body, a cooling module fixedly mounted on one side of the cold heading body, the cooling module including a water tank and a drain plate, a protective box fixedly mounted on the upper surface of the water tank, two electric push rods fixedly mounted on the bottom surface of the protective box, connecting plates fixedly mounted on the output ends of the two electric push rods, moving columns fixedly mounted on both sides of the lower end surfaces of the two connecting plates, and rotating shafts rotatably mounted on the lower end surfaces of the four moving columns;

[0007] The purification module includes a fixed box, a fixed platform is fixedly installed on one side of the bottom surface of the fixed box, an air pump is fixedly installed on the upper surface of the fixed platform, a first electrically controlled valve is fixedly installed at the output end of the air pump, a second electrically controlled valve is installed on the other side of the bottom surface of the fixed box, two activated carbon filter elements are bolted to the side of the first electrically controlled valve near the second electrically controlled valve, and a PP cotton filter element is bolted to the side of the second electrically controlled valve near the first electrically controlled valve.

[0008] Furthermore, the purification module is hinged to two cabinet doors at its front end, and each of the two cabinet doors has a handle fixedly installed on its front end.

[0009] Furthermore, a control box is bolted to the front end of the cold heading body, and a control button is fixedly installed on the upper part of the front surface of the cooling module.

[0010] Furthermore, each of the four rotating shafts has a rotatable drain plate rotatably connected to its lower end face, and a rotating block is fixedly installed at each of the four corners of the upper end face of the drain plate. A water inlet pipe is fixedly installed through the inner wall of the rear end of the protective box.

[0011] Furthermore, a water outlet pipe is fixedly installed at the lower front end of the cooling module, and a material outlet is fixedly installed on one side of the cooling module.

[0012] Furthermore, an exhaust pipe is fixedly installed on one side of the purification module.

[0013] Furthermore, an exhaust pipe is fixedly installed at the upper end of the second electronically controlled valve.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model proposes a safe flange nut cold heading machine. When making flange nuts, the cold heading machine requires extruding and forging the raw materials, resulting in high heat levels in the flange nuts immediately after production. After the flange nuts are produced, the cold heading mechanism transfers them to a cooling module. The cooling module cools the flange nuts before discharging them through the outlet. The cooling module's main structure includes a water tank for storing cold water. The upper end of a perforated plate inside the water tank is connected to an electric actuator via a rotating shaft. When the flange nut enters the upper end of the perforated plate, the electric actuator moves the perforated plate downwards into the cold water. After the flange nut is cooled, the electric actuator raises the perforated plate. When the perforated plate reaches the outlet, the electric actuator near the outlet stops working, while the electric actuator further away continues to operate, allowing the perforated plate to pour the flange nut out of the outlet.

[0016] 2. This utility model proposes a safe flange nut cold heading machine. When making flange nuts, the cold heading machine may cause raw materials to splash. Installing a protective plate and rotating cover at the cold heading body can prevent raw materials from splashing and injuring workers. At the same time, the cold heading body will generate a lot of smoke when running for a long time. The purification module can purify the smoke through the internal activated carbon filter and PP cotton filter. The purification module is equipped with two sets of activated carbon filter and PP cotton filter. If one set is damaged, the other set can be replaced to continue working. The replacement of filter will not affect the operation of the equipment. Attached Figure Description
