Description

Trolley tempering furnace for reducing spring Technical Field The application relates to the field of tempering furnaces, in particular to a tempering furnace trolley for a reducing spring. Background The diameter-variable spring is a spring with the diameter changing along the axial direction, belongs to a special-shaped spring, has the characteristics of excellent bearing capacity, good buffering effect, strong space applicability and the like, and the production process of the diameter-variable spring follows the same flow as that of a common spring and sequentially comprises pretreatment, coiling, annealing, quenching, tempering, surface treatment and inspection. At present, the Chinese patent with the publication number of CN206089744U discloses a trolley tempering furnace, which comprises a furnace body, a trolley and a control box, wherein an opening is formed in one side of the furnace body, symmetrical grooves are formed in the inner side of the opening, a furnace door is arranged on the outer side of the opening, a lifting device is connected above the furnace door, a track is arranged below the furnace door, a furnace lining is arranged on the inner wall of the furnace body, a ventilator is arranged above the furnace body, a trolley is arranged on the track, a carrying box is arranged on the outer side of the trolley, the carrying box is connected with a cam mechanism, electric heating pieces are arranged on the trolley and the furnace lining, a heat-resistant steel plate is arranged above the trolley, bumps matched with the grooves are arranged on two sides of the trolley, a spring is arranged on the side surface of the furnace door, a limiting wheel is connected below the spring, an inclined limiting plate is arranged on the outer side of the opening, and the control box is arranged on the outer side of the furnace body. Because the diameter of the reducing spring changes along the axial direction, the reducing spring rolls along the smaller end of the diameter of the reducing spring as the circle center due to the inertia effect in the process that the trolley enters the tempering furnace, even the condition that the trolley is separated from the smaller end of the diameter of the reducing spring occurs, and the personal safety of surrounding staff is threatened. Disclosure of utility model In order to reduce the separation of the reducing spring from the trolley in the trolley movement process and further ensure the safety of surrounding workers, the application provides a tempering furnace trolley for the reducing spring. The application provides a tempering furnace trolley for a reducing spring, which adopts the following technical scheme: The utility model provides a tempering furnace shallow for reducing spring, includes furnace body, track and platform truck, the track set up in on the furnace body, the platform truck includes base, mounting panel, gyro wheel and a plurality of installation pole, the gyro wheel rotates to be connected on the base, the gyro wheel is along being close to or keep away from the direction roll connection of fire door on the track, the mounting panel set up in on the up end of base, a plurality of installation poles are parallel to each other and rotate connect in on the mounting panel, the reducing spring wears to locate on the installation pole. Through adopting above-mentioned technical scheme, when the platform truck needs installation reducing spring, the staff can rotate the installation pole earlier, locate the reducing spring cover on the installation pole, later rotate the installation pole, reduce the height of reducing spring, later the staff promotes the base again, slide through the gyro wheel in the track enters into the furnace body, the furnace body carries out tempering operation to the reducing spring, after the reducing spring wears to locate the installation pole, reduce in the platform truck removal in-process, rotate because of inertial reason, reduced the condition emergence that the reducing spring breaks away from the platform truck, thereby ensure surrounding staff's safety. Optionally, still be provided with the butt board on the base, the butt board is used for the butt the installation pole is kept away from the one end of installation pole axis of rotation, works as the installation pole butt in when the butt board, the height of installation pole is followed mounting panel to the direction of butt board and is risen gradually. Through adopting above-mentioned technical scheme, the butt board is used for the butt installation pole to keep away from the removal of installation pole axis of rotation, when the reducing spring cover was located in the installation pole, because the height of installation pole risees gradually along the direction of mounting panel to butt board, and the reducing spring can be close to the axis of rotation of installation pole under the effect of gravity, and the reducing spring can't break away from th
