Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for heating furnaces, and in particular to a feeding device for heating furnaces. Background Technology

[0002] The end-feeding mechanism of the heating furnace feeding platform is driven by two hydraulic cylinders. During field use, it was found that the two hydraulic cylinders often extend asynchronously. In severe cases, this causes one end of the platform to tilt, affecting the sensor position detection and thus interrupting the automatic feeding process or continuing the next operation when the billet position is incorrect, which can easily cause equipment damage. Therefore, a feeding device for heating furnace is provided. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a feeding device for a heating furnace. By controlling the synchronous movement of two first hydraulic push rods through a diversion and collection valve, the tilting of the platform caused by asynchronous extension of the hydraulic cylinders is avoided. When the pallet is raised or lowered, the support tube slides in the guide hole of the support plate. At the same time, the distance sensor detects the position in real time and feeds it back to the controller, ensuring that the pallet is raised and lowered smoothly, preventing equipment damage and interruption of the feeding process, thus overcoming the shortcomings of existing technologies.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A feeding device for a heating furnace includes a roller conveyor belt. A base plate is fixed to the bottom of one end of the roller conveyor belt. Two first hydraulic push rods are fixed to the middle of the upper surface of the base plate. The upper ends of the two first hydraulic push rods are connected to a support plate. The hydraulic lines of the two first hydraulic push rods are centrally connected to a flow divider valve. The flow divider valve is externally connected to a hydraulic station through hydraulic lines. An L-shaped support plate is fixed to the top edge of the base plate. A pushing assembly is installed above the middle of the vertical section of the L-shaped support plate. A controller is installed on the top of one side of the vertical section of the L-shaped support plate.

[0006] As a further embodiment of this utility model: a support plate is installed at the middle of one end of the roller conveyor belt, a guide hole is opened in the middle of the support plate, a support tube is slidably inserted into the guide hole, and the upper end of the support tube is welded to the lower end face of the pallet.

[0007] As a further improvement of this utility model: the end of the support plate is provided with a connecting ear, which is connected to the roller conveyor belt by bolts.

[0008] As a further embodiment of this utility model: a detection plate is fixed to the end of the pallet away from the roller conveyor belt, and a distance sensor is installed on the lower end face of the horizontal section of the L-shaped support plate above the detection plate. The hydraulic stations of the two first hydraulic push rods and the distance sensor are electrically connected to the controller.

[0009] As a further embodiment of this utility model: the pushing assembly includes a second hydraulic push rod fixed on the vertical section of the L-shaped support plate facing the roller conveyor belt. One end of the second hydraulic push rod is connected to a pushing rod, and both ends of the pushing rod facing the L-shaped support plate are fixed with support rods. Both support rods are slidably inserted into the vertical section of the L-shaped support plate.

[0010] As a further improvement of this utility model, a stop block is fixed at the end of each of the two support rods away from the push rod.

[0011] As a further improvement of this utility model, the controller is electrically connected to the hydraulic station of the second hydraulic push rod.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The two first hydraulic push rods are controlled to move synchronously by the diversion and combination valve to avoid the tilting of the platform due to the asynchronous extension of the hydraulic cylinders; when the pallet is raised and lowered, the support tube slides in the guide hole of the support plate. At the same time, the distance sensor detects the position in real time and feeds it back to the controller to ensure that the pallet is raised and lowered smoothly and to prevent equipment damage and interruption of the feeding process.

[0014] 2. The controller can control the extension and retraction of the second hydraulic push rod of the feeding assembly, which drives the push rod to smoothly push the workpiece to the roller conveyor belt, and then the roller conveyor belt transports it to the heating furnace. After completion, each component can automatically reset, improving the automation level and efficiency of feeding. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1, referring to Figure 1-4 A feeding device for a heating furnace includes a roller conveyor belt 1. A base plate 5 is fixed to the bottom of one end of the roller conveyor belt 1. Two first hydraulic push rods 14 are fixed to the middle of the upper surface of the base plate 5. The upper ends of the two first hydraulic push rods 14 are connected to a support plate 3. The hydraulic lines of the two first hydraulic push rods 14 are centrally connected to a diversion and collection valve 8. The diversion and collection valve 8 is externally connected to a hydraulic station through hydraulic lines. An L-shaped support plate 6 is fixed to the top side of the base plate 5. A pushing assembly is installed above the middle of the vertical section of the L-shaped support plate 6. A controller 13 is installed on the top of one side of the vertical section of the L-shaped support plate 6.

[0022] A support plate 2 is installed at the middle of one end of the roller conveyor belt 1. A guide hole 12 is opened in the middle of the support plate 2. A support tube 4 is slidably inserted into the guide hole 12. The upper end of the support tube 4 is welded to the lower end face of the support plate 3.

[0023] The end of the support plate 2 is provided with a connecting ear 15, which is connected to the roller conveyor belt 1 by bolts.

[0024] A detection plate 11 is fixed to one end of the pallet 3 away from the roller conveyor belt 1. A distance sensor 17 is installed on the lower end of the horizontal section of the L-shaped support plate 6 above the detection plate 11. The hydraulic stations of the two first hydraulic push rods 14 and the distance sensor 17 are all electrically connected to the controller 13.

[0025] The workpiece is placed on the pallet 3, and the controller 13 controls the two first hydraulic push rods 14 to push the pallet 3 upward. The distance sensor 17 detects the distance between the pallet 3 and the detection plate 11 and transmits the distance information to the controller 13. When the distance value reaches the preset value, the controller 13 controls the two first hydraulic push rods 14 to stop. At this time, the workpiece is located on one side of the roller conveyor belt 1. The flow diversion and collection valve 8 facilitates the synchronous operation of the two first hydraulic push rods 14. When the pallet 3 is raised and lowered, it drives the support tube 4 to slide at the guide hole 12, ensuring the stability of the pallet 3.

Both support rods 7 are slidably inserted into the vertical section of the L-shaped support plate 6. The ends of the two support rods 7 away from the push rod 9 are fixed with a stop block 16. The controller 13 is electrically connected to the hydraulic station of the second hydraulic push rod 10.

[0028] The controller 13 controls the extension of the second hydraulic push rod 10 so that the push rod 9 pushes the workpiece onto the roller conveyor belt 1, and the roller conveyor belt 1 transports the workpiece to the heating furnace. Then the controller 13 controls the two first hydraulic push rods 14 and the second hydraulic push rod 10 to reset.
