Description

Technical Field

[0002] Screws are a common type of fastener, widely used in machinery manufacturing, construction engineering, and other fields. Heat treatment is a key process in screw production, as it can improve the mechanical properties of screws, such as increasing hardness, strength, and wear resistance. Currently, existing screw heat treatment equipment has some shortcomings in use. First, the heating is uneven, as the screws are often stationary during the heating process, resulting in inconsistent heating of different parts and affecting the quality of heat treatment. Second, the operation is not safe enough, as feeding and discharging are mostly done manually, and operators are easily exposed to high-temperature components, posing safety hazards. Accordingly, this utility model proposes a heat treatment device for screw production. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a heat treatment device for screw production, which features uniform heating and safe operation.

An induction coil is provided between the outer material cylinder and the inner material cylinder and wound around the inner material cylinder. A baffle core cylinder extending vertically is provided inside the inner material cylinder. Ball heads are provided at the upper and lower ends of the baffle core cylinder. A spiral blade is provided between the baffle core cylinder and the inner material cylinder. The inner side of the spiral blade is connected to the baffle core cylinder and the outer side is connected to the inner material cylinder.

[0007] The present invention is further configured such that a temperature sensor is provided on the outer wall of the inner material cylinder.

[0008] The present invention is further configured such that: an elastic element is connected in series on the support leg, and a vibration motor is provided on the outer material cylinder.

[0009] The present invention is further configured such that the elastic element is a compression spring.

[0010] The present invention is further configured such that the upper end of the baffle core is lower than the feed inlet and the lower end is higher than the discharge outlet.

[0011] The present invention is further configured such that the cross-sectional shape of the coolant circulation pipe is trapezoidal.

[0012] The present invention is further configured such that: the feed inlet is flared; and the discharge outlet is constricted.

[0013] The present invention is further configured such that: the inner material cylinder and the outer material cylinder are arranged on the same axis; the baffle core cylinder and the inner material cylinder are arranged on the same axis.

[0014] In summary, this utility model has the following beneficial effects: 1.
