Abstract
Description
Technical Field
[0001] This utility model relates to the field of refractory brick production technology, specifically to a blank forming device for refractory brick production. Background Technology
[0002] Refractory bricks are generally divided into two types: unshaped refractories and shaped refractories. Unshaped refractories, also called castables, are mixed powdery granules composed of various aggregates and one or more binders. They must be mixed with one or more liquids and stirred evenly before use, exhibiting strong fluidity. Shaped refractories generally refer to refractory bricks, which have standard shapes but can also be custom-cut as needed. Forming equipment is required during the processing of refractory brick blanks.
[0003] Existing refractory bricks require pressing during the manufacturing process. Most existing pressing methods involve adding the blank to a mold and hydraulically shaping it using a hydraulic device before firing. The blank needs to be kept flat when added to the mold, and existing methods mostly involve manually operating a scraper to smooth the surface, which is inefficient and cannot achieve high-efficiency production. Therefore, a blank forming device for refractory brick production is proposed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figure 1-4 This utility model provides a new technical solution: a blank forming device for refractory brick production, including a workbench 1, and a support frame 2 is fixedly installed on the upper surface of the workbench 1;
[0030] The workbench 1 is equipped with a pressing mechanism, which includes a hydraulic press 3, a hydraulic rod 4, a moving plate 5, a pressure plate 6, a collar 7, a first spring 8, a groove 9, a vertical plate 10, a lead screw 11, a scraper 12, a mold 13, a hopper 14, an electric push rod 15, an ejector block 16, a second spring 17, and a motor 18.
[0031] Furthermore, the hydraulic device 3 is fixedly installed on the upper surface of the cross plate of the support frame 2, and the hydraulic rod 4 is slidably sleeved on the inner surface of the hydraulic device 3, with the lower end of the hydraulic rod 4 sliding through the lower surface of the cross plate of the support frame 2.
[0032] Furthermore, the movable plate 5 is fixedly installed at the lower end of the hydraulic rod 4, and the pressure plate 6 is fixedly installed on the lower surface of the movable plate 5;
[0033] Two collars 7 are fixedly installed at both ends of the movable plate 5, and the two collars 7 are slidably sleeved on the outer surface of the support frame 2.
[0034] Furthermore, the mold 13 is fixedly installed on the upper surface of the worktable 1, and the groove 9 is formed on the upper surface of the worktable 1.
[0035] The hopper 14 is fixedly installed on the lower surface of the top plate of the workbench 1, and the output end of the hopper 14 is fixedly installed on the vertical plate of the workbench 1. The hopper 14 is installed in a corresponding manner with the groove 9.
[0036] Furthermore, four upright plates 10 are fixedly installed on the upper surface of the workbench 1, and two lead screws 11 are rotatably connected to the opposite surfaces of the four upright plates 10, with the left ends of the two lead screws 11 penetrating through the left surface of the upright plates 10.
[0037] Furthermore, two motors 18 are fixedly installed on the left surface of the upright plate 10, and the output ends of the two motors 18 are fixedly connected to the left ends of the two lead screws 11.
[0038] Among them, the two vertical plates of the scraper 12 are threaded onto the outer surfaces of the two lead screws 11.
[0039] Furthermore, the electric push rod 15 is fixedly installed on the upper surface of the workbench 1 base plate, and the T-shaped ejector block 16 is fixedly installed on the output end of the electric push rod 15.
[0040] Among them, two second springs 17 are fixedly installed on the upper surface of the T-shaped ejector block 16 horizontal plate, and the upper ends of the two second springs 17 are fixedly installed on the lower surface of the top plate of the workbench 1.
[0041] When using the blank forming device for refractory brick production, the blank is added to the mold 13. The motor 18 is started, and its operation drives the lead screw 11 to rotate. At this time, the scraper 12, threaded on the outer surface of the lead screw 11, scrapes away excess blank from the surface of the mold 13 through the threads. The excess blank falls into the discharge hopper 14, where waste is discharged. Then, the hydraulic actuator 3 is started, and its operation drives the hydraulic rod 4, which is slidably fitted on its inner surface, to move downward. The hydraulic rod 4 applies a downward thrust to the movable plate 5, which is fixedly installed at its lower end. The collar 7, which is fixedly installed at both ends, moves downward on the outer surface of the two uprights of the two support frames 2. At the same time, the collar 7 applies pressure to the first spring 8, which is fixedly installed on the lower surface, causing it to contract. The elastic potential energy of the first spring 8 itself forms a certain buffer. After the stamping is completed, the elastic restoring force of the spring 8 is used to pull the moving plate 5 and the pressure plate 6 back to the initial position, reducing the impact force generated during stamping and protecting the stamping mechanism. At this time, the electric push rod 15 is activated, and the electric push rod 15 applies an upward thrust to the ejector block 16, which is fixedly installed at the output end. The ejector block 16 can eject the formed refractory brick.
[0042] The blank forming device for refractory brick production can use a motor 18 to drive a scraper 12 to scrape off excess blank material on the surface of the mold 13, ensuring the cleanliness of the working area around the mold 13, or to evenly distribute the blank material in the mold 13, improving the forming quality of the product. The blank material is discharged through the hopper 14 and can be recycled. The blank forming device for refractory brick production uses the elastic potential energy of the first spring 8 to form a certain buffer. After the stamping is completed, the elastic restoring force is used to pull the moving plate 5 and the pressure plate 6 back to the initial position, reducing the impact force generated during stamping and protecting the stamping mechanism.
[0043] Structural Description:
[0044] Workbench 1: As the basic support structure of the entire device, it bears all other components of the device and provides a stable platform for the installation and operation of other components.
[0045] Support frame 2: It is fixedly installed on the upper surface of the workbench 1 to provide installation positions for components such as hydraulic unit 3, ensuring the stability and height of these components during operation, thereby providing sufficient space for pressing operations.
[0046] Hydraulic unit 3: It is the power source for the pressing operation. Through the pressure transmission principle of the internal liquid, it converts electrical energy or other forms of energy into hydraulic energy, which drives the extension and retraction of the hydraulic rod 4. In this device, hydraulic unit 3 provides the required pressure for the entire pressing process, enabling it to press the refractory brick blank into shape.
[0047] Hydraulic rod 4: It is the actuator of hydraulic device 3. Under the hydraulic pressure generated by hydraulic device 3, it performs telescopic movements. It transmits the pressure of hydraulic device 3 to moving plate 5, thereby driving pressure plate 6 to move up and down, so as to press the blank in mold 13.
[0048] Movable plate 5: As an intermediate connecting component, it transmits the movement of hydraulic rod 4 to pressure plate 6. Its movement directly affects the position of pressure plate 6, ensuring that pressure plate 6 can perform pressing operations stably.
[0049] Pressure plate 6: It is in direct contact with the refractory brick blank. When the hydraulic rod 4 pushes the moving plate 5 down, the pressure plate 6 applies pressure to the blank in the mold 13, pressing it into the required shape and density. It is a key component for blank forming.
[0050] The collar 7 is slidably sleeved on the outer surface of the support frame 2 and installed at both ends of the movable plate 5. Its main function is to provide guidance and limit for the up and down movement of the movable plate 5, to ensure that the movable plate 5 will not deviate during the up and down movement, to ensure the accuracy and stability of the pressing action, and to enable the pressure plate 6 to accurately press the blank in the mold 13.
[0051] First spring 8: Fixed on the upper surface of workbench 1, it is a container and shape template for blank forming. It specifies the shape and size of the refractory brick and shapes the blank placed in it into the shape of the final product through a pressing operation.
[0052] Groove 9: Located on the upper surface of the workbench 1, it provides a channel and space for the hopper 14 to transport the blank, ensuring that the blank can accurately enter the mold 13, avoiding the blank from scattering or overflowing, and improving the accuracy of blanking.
[0053] Vertical plate 10: As a support structure for lead screw 11, it is fixedly installed on the upper surface of workbench 1 to ensure the position and stability of lead screw 11 and provide basic support for the rotation of lead screw 11.
[0054] Lead screw 11: Rotatably connected between the vertical plates 10, providing power transmission for the left and right movement of the scraper 12. By rotating, the lead screw 11 can drive the scraper 12 to move along its axial direction, realizing the scraping or cleaning operation on the upper surface of the worktable 1.
[0055] Scraper 12: Its vertical plate is threaded onto the outer surface of the lead screw 11. It can move left and right by rotating the lead screw 11. It can be used to scrape off excess blank material to keep the working area around the mold 13 clean, or to distribute the blank material evenly in the mold 13 to improve the molding quality of the product.
[0056] Mold 13: Fixed on the upper surface of workbench 1, it is a container and shape template for blank forming. It specifies the shape and size of the refractory brick and shapes the blank into the final product through a pressing operation.
[0057] The feeding hopper 14 is fixedly installed on the lower surface of the top plate of the workbench 1. Its output end is connected to the vertical plate of the workbench 1. Its main function is to discharge the blank waste.
[0058] Electric push rod 15: Fixedly installed on the upper surface of the workbench 1 base plate, it provides power to the ejector block 16. After the refractory brick is formed, the electric push rod 15 pushes the ejector block 16 upward to eject the formed refractory brick from the mold 13, making it easy to remove the finished product.
[0059] Ejector block 16: Ejects the formed refractory brick from the mold 13 to ensure that the formed refractory brick can be demolded smoothly and to avoid damage to the product during the brick removal process.
[0060] The second spring 17 plays a role in buffering and resetting during the up-and-down movement of the ejector block 16. After the ejector block 16 pushes the refractory brick upward, the second spring 17 can help the ejector block 16 return to its initial position after completing the ejection operation, while reducing the impact of the ejector block 16 during movement and extending the service life of the component.
[0061] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
