DETAILED DESCRIPTION

[0015] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", "vertical", "horizontal", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] like Figures 1 to 3As shown, the embodiment of the utility model includes a preheating furnace 1, which has an opening at the front side, and is provided with a furnace door 2 and a door lock assembly 3 in front for closing the opening; a resistance wire is provided in the furnace wall lining of the preheating furnace 1, and is connected with a resistance wire heating device 4 arranged on the outside of the preheating furnace 1; an exhaust port 5 with a valve is provided on the top of the preheating furnace 1 and is connected with the interior thereof; two tracks 6 are provided at the bottom of the preheating furnace 1 for slidingly connecting a wheeled vehicle body 7 for placing a mold; a handle 8 is vertically provided at the front end of the wheeled vehicle body 7, and slide grooves are provided on the left and right sides of the handle, and a U-shaped rod 9 is slidably connected through a slider 901, and support rods 10 are provided at the bottom of both ends of the U-shaped rod 9, which are used to support the front end of the wheeled vehicle body 7 when it is moved out of the preheating furnace 1; a fixing assembly 12 is provided on the U-shaped rod 9, which is used to fix the U-shaped rod 9 in conjunction with the fixing sockets 801 provided on the upper and lower sides of the handle 8.

[0018] Preferably, the fixing assembly 12 is composed of a connecting rod 1203 as the main body, and both ends of the connecting rod 1203 are provided with pins 1201 that penetrate the U-shaped rod 9 and are used to be plugged into the fixed socket 801 on the handle 8; an elastic member 1202 is provided between the connecting rod 1203 and the U-shaped rod 9, and the elastic member 1202 is sleeved on the outside of the pin 1201.

[0019] When it is necessary to preheat the track core metal forming mold, first open the furnace door 2, and then pull the wheeled vehicle body 7 to move out of the preheating furnace 1 through the handle 8. When the front end of the wheeled vehicle body 7 moves out of the preheating furnace 1, pull the connecting rod 1203 to make the pin 1201 disengage from the fixed socket 801 on the upper side of the handle 8, and the U-shaped rod 9 slides downward through the slider 901, so that the bottom end of the support rod 10 contacts the ground. A roller 11 can also be provided at the bottom of the support rod 10 to facilitate the subsequent pulling of the wheeled vehicle body 7. When the roller 7 contacts the ground, the pin 1201 corresponds to the fixed socket 801 on the upper and lower sides of the handle 8. Under the action of the elastic member 1202, the pin 1201 is inserted into the fixed socket 801, so that the U-shaped rod 9 can be fixed, which plays a supporting role for the front end of the wheeled vehicle body 7.

[0020] Next, place the forming mold on the wheeled vehicle body 7, pull the connecting rod 1203 to disengage the pin 1201 from the lower fixed socket 801, pull the U-shaped rod 9 upward so that the pin 1201 is inserted into the upper fixed socket 801, fix the U-shaped rod 9 and the support rod 10, and then push the wheeled vehicle body 7 and the forming mold thereon into the preheating furnace 1.

[0021] Then the furnace door 2 is closed. An inner groove 101 is provided at the opening of the preheating furnace 1, and a boss 201 is provided on the inner side of the furnace door 2. When the furnace door 2 is closed, the boss 201 is embedded in the inner groove 101 to improve the sealing effect. Then the resistance wire heating device 4 is started, and the resistance wire arranged in the lining of the preheating furnace 1 is energized to increase the temperature in the preheating furnace 1, and the forming mold is preheated to 250°C~300°C, so that the forming mold has more toughness and is not easy to break during the subsequent forging processing.

[0022] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
