At present, the heat-pressing treatment of springs in China is generally carried out manually and with professional molds, and some spring heat-pressing machines also perform the heat-pressing process in the machine cavity. This will consume a lot of manpower and energy, and it will also make it difficult for operators to observe and control well, and it is also easy to cause burns during operation. Summary of the invention

[0003] In order to overcome the above-mentioned defects, the present invention provides a tailgate spring hot pressing machine, which can better observe and control the hot pressing process and also prevent burns to personnel during manual operation.

[0004] The technical solution adopted by the present invention to solve its technical problems is: a tailgate spring hot pressing machine, including a discharge port, a casing, a feed port and a conveyor belt (for placing and transmitting the spring to be processed), the inner cavity wall of the casing is covered with heating rods (for heating the cavity), the conveyor belt is arranged in the inner cavity of the casing, the feed port and the discharge port are located at both ends of the conveyor belt, the feed port and the discharge port are outside the casing, a blower is arranged above the casing, the blower is communicated with the inner cavity of the casing, a temperature detection device for detecting the temperature of the inner cavity of the casing is provided, and a first and a second cylinder are also provided, the first cylinder is arranged at At the discharge port, the second cylinder is arranged at the feed port. The second cylinder can press the spring on the conveyor belt. A pressing and holding device is arranged. The pressing and holding device can just press the spring pressed by the second cylinder. After the pressing and holding device presses the spring, the second cylinder retracts. The spring remains in the pressed state. The conveyor belt moves and enters the inner cavity of the casing for heating. The first cylinder can just open the pressing and holding device to press the spring. The spring is released from the compressed state. At this time, the spring on the conveyor belt moves to the discharge port with the conveyor belt. The manipulator at the discharge port takes out the hot-pressed spring. That is, in this case, the strong pressure state is maintained and then heated.

[0005] A further technical solution of the present invention is: the structure of the pressing and holding device is: a rotatable rotating rod is provided on the conveyor belt, and the spring can be pressed by rotating the rotating rod, and the pressing of the spring can be released by rotating the rotating rod. For example, the first cylinder first supports the rotating rod, and then rotates itself, driving the rotating rod to slowly release the pressing on the spring. At the same time, the first cylinder slowly retracts, and the spring slowly recovers its normal elasticity. The conveyor belt continues to move, and the spring reaches the discharge port, and the robot takes it away. Of course, there are many structures of the pressing and holding device, and this example will not give examples one by one.

[0006] A further technical solution of the present invention is that a groove for placing the spring is provided on the conveyor belt.

[0007] A further technical solution of the present invention is that the temperature detection device is arranged around the blower.

[0008] The benefits of the present invention are: since the feed port and the discharge port in this example are located at the two ends of the conveyor belt, a blower is provided above the casing, the blower is communicated with the inner cavity of the casing, a temperature detection device for detecting the temperature of the inner cavity of the casing is provided, and a first and a second cylinder are provided, the first cylinder is provided at the discharge port, and the second cylinder is provided at the feed port, the second cylinder can press the spring on the conveyor belt, the spring remains in a pressed state and enters the inner cavity of the casing for heating, the first cylinder can just open the pressing holding device to press the spring, that is, unlock the pressing, the spring moves with the conveyor belt to the discharge port, and the manipulator located at the discharge port takes out the hot-pressed spring. It can be seen that in this example, the material is automatically loaded, and the conveyor belt passes through the strong pressure device in sequence (after the second cylinder is pressed, the pressing and holding device can just press the spring pressed by the second cylinder and hold it, and the second cylinder retracts), the heating device and the unlocking device (the first cylinder is unlocked), and finally the robot takes the material. Therefore, the operator can effectively observe the hot pressing situation. At the same time, the spring is always in a strong pressure state during the heating process, which can better improve the mechanical properties of the spring. Finally, the material is automatically unloaded after the discharge port is unlocked, saving labor costs and reducing the risk of scalding. BRIEF DESCRIPTION OF THE DRAWINGS
