Description

Technical Field

[0001] This invention relates to a bolt production equipment. Background Technology

[0002] Bolt: A mechanical part, a cylindrical threaded fastener used with a nut. It is a type of fastener consisting of a head and a shank (a cylinder with external threads), which needs to be used with a nut to fasten two parts with through holes.

[0003] During the bolt production process, the bolts need to be heat-treated, and after the heat treatment is completed, the bolts need to be cooled.

[0004] Bolts are generally mass-produced, and the produced bolts are usually distributed in multiple pallets. Then, the multiple pallets are placed into an openable, sealed box for unified heat treatment and cooling.

[0005] To more efficiently heat-treat and cool the bolts in the tray, an electric heating module and a refrigerant channel are built into the tray, and a refrigerant circulation supply module is configured for the refrigerant channel. The bolts in the tray are directly heated by the built-in electric heating module for heat treatment. After heat treatment, circulating refrigerant is supplied to the refrigerant channel in the tray through the refrigerant circulation supply module to directly cool the bolts in the tray.

[0006] Generally, all pallets use the same heating power and the same refrigerant supply flow rate. However, since the number of screws in each pallet is not uniform, there may be more or less, or even a significant difference. This can cause the bolts in some pallets to not be heated or cooled sufficiently, while the bolts in other pallets are overheated or overcooled. Therefore, it is necessary to coordinate and control the heat treatment and cooling of different pallets to avoid the above problems and save energy. Summary of the Invention

[0007] The purpose of this invention is to provide a bolt production equipment, including an openable sealed box; the box is provided with multiple trays for carrying bolts; each tray is equipped with an electric heating module; each tray is also independently equipped with a weighing module, the tray is supported by the corresponding weighing module, and the weighing module weighs the corresponding tray; the electric heating module of each tray and each weighing module are respectively connected to a main control device.

[0008] When heat-treating the bolts on the pallet, the main control device controls the heating power of the electric heating modules according to the weight of the pallet, so that the ratio of the heating power of each electric heating module is equal to the ratio of the weight of the pallet to which each electric heating module is located.

[0009] Preferably, each tray also has a built-in refrigerant channel, and each tray's refrigerant channel is independently equipped with a refrigerant circulation supply module. The refrigerant channel of the tray is supplied with circulating refrigerant by the corresponding refrigerant circulation supply module; each refrigerant circulation supply module is connected to the main control device.

[0010] When cooling the bolts on the tray, the main control device controls the refrigerant supply flow rate of the refrigerant circulation supply module according to the weight of the tray, so that the ratio of the refrigerant supply flow rate of each refrigerant circulation supply module is equal to the ratio of the weight of each electric heating module on the tray.

[0011] Preferably, each tray is a heat-conducting tray.

[0012] Preferably, each pallet has the same weight.

[0013] Preferably, all trays have the same structure.

[0014] Preferably, the refrigerant channels in each tray have the same structure.

[0015] The advantages and beneficial effects of the present invention are as follows: It provides a bolt production equipment that can coordinate and control the heat treatment and cooling of bolts in different trays, avoiding the situation where bolts in some trays are not sufficiently heated or cooled, while bolts in other trays are overheated or overcooled; thereby improving the efficiency of bolt heat treatment and cooling, saving energy consumption, and increasing production capacity.
