Description

Technical Field

[0001] This utility model relates to the field of sintered hollow brick technology, specifically to a pre-forming device for sintered hollow bricks. Background Technology

[0002] Hollow bricks are commonly used in non-load-bearing parts. They have a porosity of not less than 40% and are characterized by large but few hollow spaces. Hollow bricks are classified into cement hollow bricks, clay hollow bricks, and shale hollow bricks. Hollow bricks are a commonly used wall material in the construction industry. Due to their advantages such as being lightweight and consuming less raw materials, they have become the first product recommended by the national construction department.

[0003] In existing technologies, when shaping sintered hollow bricks, the materials need to be mixed and placed into a mold for pressing and shaping. However, most existing technologies use manual pressing, which can lead to uneven force distribution. This results in insufficient compression force in some parts of the sintered hollow bricks after shaping, affecting the quality of the sintered hollow bricks. In addition, after the sintered hollow bricks are shaped, they need to be poured out, which is time-consuming and labor-intensive, affecting work efficiency. Utility Model Content

[0010] Preferably, the lower edge of the push plate and the upper edge of the box are located on the same horizontal plane.

[0011] The pre-forming equipment for sintered hollow bricks provided by this utility model has the following advantages: It adopts a push rod in conjunction with a pressure plate, a box body and a fixing component to realize the automatic extrusion and shaping operation of sintered hollow bricks.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Example 1

[0017] Please see Figure 1-2 A pre-forming device for sintered hollow bricks includes a base 1, a gate-shaped support frame 2 installed in the middle of the top surface of the base 1, hydraulic push rods 3 on both the left and right sides of the front end of the support frame 2, pressure plates 4 connected to the output ends of the hydraulic push rods 3, and guide rods 15 on both sides of the front end of the support frame 2. The pressure plates 4 pass through the guide rods 15 and are slidably connected to the guide rods.

[0018] An assembly cavity 5 is provided in the middle part of the upper side of the base 1. A box 6 is provided inside the assembly cavity 5. A middle pressure plate is provided in the middle of the pressure plate 4 corresponding to the box 6. A hole forming rod is provided on the lower side of the middle pressure plate. A row of first electric push rods 7 is provided below the box 6 at the bottom of the assembly cavity 5. One end of the first electric push rod 7 passes through the bottom surface of the box 6 and extends into the box 6. The top end of the first electric push rod 7 is connected to an ejector plate 8. A second electric push rod 9 is provided on the top surface of the base 1 on one side of the support frame 2. The output end of the second electric push rod 9 is connected to a push plate 10. The lower edge of the push plate is on the same horizontal plane as the upper edge of the box.

[0019] Fixing components are provided on both the left and right sides of the box 6.

[0020] The fixing assembly includes a third electric push rod 11, a plug block 12, a strip groove 13, and a plug rod 14.

[0021] The third electric push rod 11 is installed on one side of the upper part of the housing 6 inside the assembly cavity 5. The insert block 12 is connected to the output end of the third electric push rod 11, with the output end of the third electric push rod 11 facing the housing 6. A strip groove 13 is formed on the upper side of the side wall of the housing 6. The insert rod 14 is installed on one side of the bottom of the pressure plate 4, corresponding to the position of the strip groove 13. The lower side of the insert rod is provided with a positioning hole corresponding to the insert block. The insert block can be inserted into the strip groove and the positioning hole.

[0022] During the pre-shaping operation of sintered hollow bricks, the first electric push rod 7 first drives the ejector plate 8 to retract into the box 6, and then the required material is fed into the box 6. Then, the hydraulic push rod 3 is controlled to run, and the pressure plate 4 is driven down, and the insertion rod 14 is inserted into the strip groove 13. At this time, the pressure plate 4 is subjected to vertical and uniform pressure from the hydraulic push rod 3. With the help of the box 6, the shaping operation of the sintered hollow bricks can be completed. At the same time, the third electric push rod 11 pushes the insertion block 12 through the strip groove 13 and connects with the positioning insertion hole, thereby limiting and maintaining the position of the pressure plate 4, thus increasing the shaping effect of the sintered hollow bricks.

[0023] After the shaping is completed, the hydraulic push rod 3 drives the pressure plate 4 to reset. At this time, the first electric push rod 7 runs and pushes the shaped sintered hollow brick out of the box 6 through the ejector plate 8. At this time, the upper edge of the ejector plate 8 will be flush with the upper edge of the box 6. Then the second electric push rod 9 runs and pushes the sintered hollow brick located at the top of the ejector plate 8 and the shaping is completed through the push plate 10, thereby completing the automatic unloading of the sintered hollow brick after shaping.

[0024] Guide rods 15 are set on both sides of the front end of the support frame 2. The two sides of the pressure plate 4 are slidably connected to the guide rods 15 to increase the stability of the pressure plate 4 during vertical movement.

[0025] 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.
