Description

Technical Field

[0001] The utility model relates to the technical field of fasteners, especially the technical field of a blank nut feeding device. Background Art

[0002] A nut is a part that tightly connects mechanical equipment. Through the internal thread, it can cooperate with a bolt of the same specification to achieve functions such as fixed connection, and it is used in many fields. For some nuts with larger sizes, the nut blanks are often produced by forging and punching, and then subsequent tapping processing is carried out. In the process of manufacturing nut blanks, the forging of nuts is divided into hot forging and cold forging. Cold forging is a forging process of pressure processing on metal materials in a room temperature state, while hot forging is a forging process in which metal materials are heated above the recrystallization temperature and then subjected to pressure processing. Hot-forged nuts have high strength and good toughness, but the temperature of the nuts after hot forging is relatively high, with greater danger and difficulty in operation. After hot forging, the nuts need a feeding device to hold them. The heat dissipation effect of the existing feeding device is average, and the time required for the nuts to cool is relatively long.

[0003] The existing patent CN108655329A discloses a feeding device for hot-forged nut blanks with good cooling effect, which cools the nut blanks by means of water cooling. However, since the water does not directly contact the nut blanks, the cooling effect is still not ideal. Summary of the Invention

[0004] The purpose of the utility model is to solve the problems in the existing technology and propose a blank nut feeding device that can quickly cool down, enabling the nut blanks to quickly cool down under the action of cold air.

[0005] To achieve the above purpose, the utility model provides a blank nut feeding device that can quickly cool down, including a material guiding groove, air blowing holes, an air guiding box, a chip storage box, and an air blowing pipe. The material guiding groove is composed of a material guiding plate and a baffle. The material guiding plate is a long strip-shaped plate body that slopes downward in the length direction. On both sides of the upper end surface of the material guiding plate, there are baffles. The lower end surface of the material guiding plate is provided with a long strip-shaped air guiding box. The length direction of the air guiding box is the same as that of the material guiding groove. The bottom wall of the air guiding box is a plate body parallel to the material guiding plate. There are several air blowing holes on the material guiding plate, and the air blowing holes communicate the inside of the material guiding groove and the inside of the air guiding box. An air blowing pipe is installed on the air guiding box, and the air blowing pipe is connected to the inside of the air guiding box. A chip storage box is installed on the bottom wall of the air guiding box, and the chip storage box is connected to the air guiding box. The chip storage box is located at the lowest position of the bottom wall of the air guiding box.

[0006] Preferably, several supporting feet are provided at the bottom of the air guiding box.

[0007] Preferably, a sealing gasket is provided between the air guiding box and the material guiding plate.

[0008] Preferably, the air blowing holes are strip-shaped, and the length direction of the air blowing holes is perpendicular to the length direction of the material guiding plate.

[0009] Preferably, the air blowing pipe is installed at the highest position of the air guiding box.

[0010] Preferably, the bottom wall of the chip storage box is provided with a sealed opening and closing door.

[0011] The beneficial effects of the present utility model are as follows: By installing the air blowing pipe on the air guiding box, the air guiding box is installed at the bottom of the material guiding groove, and the air blowing holes are arranged on the material guiding plate, the nut blanks can be effectively air-cooled when moving along the material guiding groove, and the nut blanks can be quickly cooled down; the setting of the chip storage box enables the dropped oxide scales to be effectively collected, which is convenient for the subsequent treatment of the oxide scales.

The material guiding groove 1 is composed of a material guiding plate 11 and a baffle 12. The material guiding plate 11 is a strip-shaped plate body that slopes downward in the length direction. Baffles 12 are provided on both sides of the upper end surface of the material guiding plate 11. The lower end surface of the material guiding plate 11 is provided with a strip-shaped air guiding box 2.

The bottom wall of the air guiding box 2 is a plate body parallel to the material guiding plate 11. A plurality of air blowing holes 10 are provided on the material guiding plate 11. The air blowing holes 10 communicate the inside of the material guiding groove 1 and the inside of the air guiding box 2. An air blowing pipe 20 is installed on the air guiding box 2. The air blowing pipe 20 is communicated with the inside of the air guiding box 2. The air blowing pipe 20 is connected to a gas supply device. The gas supply device can be a blower or a compressed air generator. A chip storage box 21 is installed on the bottom wall of the air guiding box 2. The chip storage box 21 is communicated with the air guiding box 2. The chip storage box 21 is located at the lowest position of the bottom wall of the air guiding box 2.

[0017] A plurality of support feet 25 are provided at the bottom of the air guide box 2.

[0018] In order to ensure the sealing between the air guide box 2 and the material guide plate 11, so that the air blown out by the air blowing pipe 21 leaves from the air blowing holes 10, a sealing gasket is provided between the air guide box 2 and the material guide plate 11.

During the sliding process, the air blowing pipe 20 continuously passes cold air into the air guide box 2. The cold air in the air guide box 2 leaves from the air blowing holes 10 and blows over the nut blanks, and the nut blanks are rapidly cooled. During this process, some of the scale on the nut blanks falls off under the action of cold shrinkage and collision. The scale falls into the air guide box 2 through the air blowing holes 10 and finally falls into the chip storage box 21 at the bottom of the air guide box 2. Opening the sealed opening and closing door 2 can clean the scale in the chip storage box 21.
