Description

Technical Field

[0001] The utility model relates to the field of heat treatment and forging, in particular to heat treatment equipment. Background Art

[0002] In the field of forging, heat treatment is a necessary process for every forging. When the heating furnace heats the forging, after putting it into the heating furnace for heating, when it needs to be taken out, the furnace door of the heating furnace is generally opened, and the staff takes the forging out of the heating furnace. There are two ways to take it out from the heating furnace: the first is that the bracket at the bottom of the heating furnace moves on the ground. After the heating furnace is opened, the bracket drives the forging out of the heating furnace, and then the staff uses the lifting equipment to lift the forging out. The second is that after the heating furnace is opened, a forklift or a forging manipulator is used to reach into the heating furnace and take out the forging.

[0003] For small forgings, the size of the heating furnace will be smaller, and forklifts and forging operators are not very convenient. Generally, operators use long pliers to take the forgings out of the heating furnace. However, after the furnace door is opened, the high temperature of the heating furnace will be emitted. During the process of material removal, if the material removal is smooth (the operator uses pliers to clamp the forging smoothly), the operator can take out the forging in a very short time, and the operator can tolerate the high temperature of the heating furnace during this period. If the material removal is not smooth (the pliers do not hold the forging smoothly), the operator needs to temporarily leave the heating furnace and wait for the time when the high temperature of the heating furnace can be briefly accepted again before taking the material again. Or replace another operator to take the material. It is very inconvenient and will also cause energy loss. Summary of the invention

[0025] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0026] Example 1: See Figures 1 to 3 As shown, a heat treatment device comprises a heating furnace 2 having a heating chamber 1 therein, a furnace door 3 for opening and closing the heating chamber 1 of the heating furnace 2 is provided at the right end of the heating furnace 2, a feeding rack 4 is also provided at the right end of the heating furnace 2, the top surface of the feeding rack 4 is tilted downward from left to right, and a clearance 5 is provided between the feeding rack 4 and the furnace door 3;

[0027] The middle part of the furnace door 3 is provided with a discharge port 6 with two ends passing through, and a connecting support frame 7 is also provided on the furnace door 3 below the right end of the discharge port 6, and the top surface of the connecting support frame 7 is arranged parallel to the top surface of the feeding frame 4;

[0028] When the furnace door 3 moves upward so that the discharge port 6 faces the heating chamber 1, the heating furnace 2 is opened by the furnace door 3, the top surface of the connecting support frame 7 is flush with the top surface of the feeding frame 4, and the top surface of the right end of the connecting support frame 7 is arranged close to the top surface of the left end of the feeding frame 4;

[0029] When the furnace door 3 moves downward so that the discharge port 6 is disposed at the lower right side of the heating chamber 1 , the heating furnace 2 is closed by the furnace door 3 , and the top surface of the connecting support frame 7 is disposed at the lower left side of the top of the feeding frame 4 .

[0030] In this embodiment, in actual use, the heating furnace is used to heat forgings, wherein a columnar part or a pipe is taken as an example, the pipe is placed in the heating chamber of the heating furnace, the furnace door is closed, and the pipe is heated in the heating chamber of the heating furnace. After heating to a predetermined temperature and a predetermined time, the furnace door is moved upward so that the heating chamber of the heating furnace is opened. After opening, the discharge port is directly opposite to the heating chamber, and the bottom of the discharge port is directly opposite to the bottom of the heating furnace. Then, the operator reaches into the heating chamber through a tool and applies some external force, so that the pipe is subjected to a rightward pulling force and rolls to the right, and it rolls to the right from the discharge port to the connecting support frame. Since the top surface of the connecting support frame is parallel to the top surface of the feeding frame, both are inclined downward from left to right, therefore, the pipe rolls to the right, and rolls to the feeding frame through the support of the connecting support frame, and rolls to the right through the feeding frame. Among them, a platform can be set at the right end of the feeding frame, or the equipment of the subsequent process can be used to process the pipe, or other heat treatments. In this way, it is convenient for operators to take materials from the heating furnace with low labor intensity, and the time they stay at the heating furnace is shorter, the difficulty of taking materials is lower, and the safety of taking materials is better.

[0031] The top surface of the left end of the connecting support frame is flush with the bottom surface of the discharge port. In this way, when the operator pulls the pipe from the heating chamber to the discharge port, a little external force is applied, or the pipe rolls to the connection support frame smoothly by its own inertia, and is sent out by rolling to the right through the top slope.

[0032] Furthermore, the feeding frame and the connecting support frame are both hollow structures, which can reduce weight and materials, and at the same time, the forgings sent out from the heating furnace are high-temperature forgings, which is also convenient for heat dissipation, thereby extending its service life.

[0033] See also Figures 1 to 3As shown, a reinforcement frame 8 is respectively provided at the front and rear sides of the bottom of the connecting support frame 7 , and the left side of the reinforcement frame 8 is connected to the right side wall of the furnace door 3 .

[0034] The reinforcement frame is provided to prevent the right end of the connecting support frame from being deformed by the weight of the forging frequently due to being far away from the furnace door. The reinforcement frame can increase the strength of the connecting support frame and extend its service life.

[0035] See also Figures 1 to 3 As shown, the top front side and the rear side of the feeding frame 4 are respectively provided with a first limiting frame 9, and the top front side and the rear side of the connecting support frame 7 are respectively provided with a second limiting frame 10.

[0036] By setting the first limit frame and the second limit frame, the high-temperature forgings can be placed above the connecting support frame and the feeding frame to prevent them from falling from the front and back of the connecting support frame and the feeding frame, so that the forgings can only move to the right, ensuring the safety of discharging.

[0037] Example 2: See Figure 4 As shown, a heat treatment equipment, the structure of which is basically the same as that of the first embodiment, except that: a plurality of feeding drive rollers 11 are installed in the feeding rack 4 so as to rotate from left to right at intervals, the top outer surface of the feeding drive roller 11 is arranged above the top surface of the feeding rack 4, and each of the feeding drive rollers protrudes from the corresponding position of the feeding rack at the same height;

[0038] A plurality of discharge drive rollers 12 are installed in the connection support frame 7 so as to rotate from left to right at intervals. The top outer surfaces of the discharge drive rollers 12 are arranged above the top surface of the connection support frame 7, and each of the discharge drive rollers protrudes from the corresponding position of the connection support frame at an equal height.

[0039] The top outer surface of the leftmost discharge driving roller is arranged flush with the bottom surface of the discharge port.

[0040] Through the arrangement of the feeding drive roller and the discharging drive roller, for non-columnar and tubular forgings, after the forgings are pulled out of the heating furnace, they are against the discharging drive roller, and the forgings can smoothly move to the right onto the feeding drive roller through the rolling support of the discharging drive roller, and quickly move to the right and fall through the rolling support of the feeding drive roller. In this way, the forgings can be guaranteed to move stably to the right, and the discharging stability can be guaranteed.

[0041] Furthermore, a support roller 13 is rotatably mounted at the bottom of the discharge port, and the top outer surface of the leftmost discharge drive roller is flush with the top outer surface of the support roller.

[0042] In this way, when the forging is pulled out of the heating furnace and passes through the discharge port, the support roller also plays a rolling support and guiding role to ensure that the forging moves smoothly to the discharge transmission roller. Among them, the top surface of the support roller will be set flush with the bottom surface of the heating chamber to ensure that the forging can be pulled out of the heating furnace smoothly.
