Description

Technical Field

[0001] The utility model relates to the field of piston rod processing, in particular to a piston rod heating device. Background Art

[0002] The piston rod of the hydraulic cylinder is a key component of the cylinder and also a vulnerable component. During the construction process, the piston rod is exposed to the outside and is prone to bruises. Bumps on the piston rod can cause scratches on the seal and oil leakage. Severe oil leakage can cause the machine to stop working, seriously affecting the service life and performance of the cylinder.

[0003] The shortcomings of general quenching devices are: the existing traditional piston rod heat treatment devices generally clamp the top of the piston plate, and the heating device slides on the outside of the piston rod for heating and then quenching. Due to the high temperature, the piston rod is easily squeezed and deformed. In addition, local heating is likely to cause uneven heating, affecting the treatment effect. Application No.: CN202320636045.2 proposes a rapid quenching device for piston rod heat treatment. By providing a clamping device on the heating unit, the piston rod can be easily placed between the corresponding two fixed columns without squeezing the piston rod, effectively avoiding the piston rod from being deformed by heat. The clamping device can meet the heating of several piston rods at the same time, and the heater can heat them evenly. The quenching unit provided in addition can not only evenly quench the heated piston rod, but the quenched water can also be recycled through the water pipe to save resources.

[0004] However, the rapid quenching device does not disclose the heating method and heating speed of its heater, and its heating unit occupies a large space and requires a rotating mechanism, resulting in a complex structure. Summary of the invention

[0005] In order to make the heating process of the piston rod faster, occupy less space, and reduce the complexity of the device, the utility model designs a piston rod heating device, whose structure includes: a heating barrel with two ends passed through, and a plurality of turns of induction coils are fixed to the inner wall of the heating barrel; a pipe mouth with an inner wall that is a conical surface that is smaller at the bottom and larger at the top is provided on the top of the heating barrel, and is covered with a barrel cover that matches the inner wall of the pipe mouth; a lifting ear is provided on the top of the barrel cover, and a plurality of hooks are provided on the bottom; the wiring harnesses at both ends of the induction coil are led out from one side of the heating barrel and connected to a control box; the heating barrel is placed on a base, and an exhaust pipe is provided on one side of the base, and the exhaust pipe is connected to the inner cavity of the heating barrel through a channel in the base.

[0006] Preferably, the heating barrel is made of ceramic or stone.

[0007] Preferably, a plurality of protrusions are fixed on the bottom of the heating barrel, and a limiting groove is provided on the base for placing the heating barrel and limiting the position. The inner diameter of the limiting groove is equal to the outer diameter of the bottom of the heating barrel, and the side wall of the limiting groove is also provided with a groove matching the protrusion to prevent the heating barrel from rotating.

[0008] Preferably, the barrel cover is also made of ceramic or stone.

[0009] The utility model adopts high-frequency induction heating. When in use, the piston rod is hung on the hook, and then the barrel cover is lowered to cover the heating barrel. The piston rod hung on the hook can be heated in the shortest time, and a vacuum heating environment can be provided at the same time. After the heating is completed, the barrel cover is lifted to carry out subsequent processing operations. The utility model occupies a small space, heats quickly, and has a simple structure.
