Technical Field
[0001] This utility model relates to the field of refractory brick material production, specifically a tooling for checker bricks in the regenerator of a glass kiln. Background Technology
[0002] When manufacturing checker bricks for the regenerator chambers of glass kilns for clients, a small number of bottom checker bricks require a metal support frame nested within the brick for stronger support. During molding, the metal support frame needs to be pre-fixed before molding. The structure of the checker brick consists of... Figure 1 As shown, the brick body has a channel structure that is narrower at the top and wider at the bottom. To improve the supporting strength of the brick body, a metal support frame is installed on the outside of the channel structure. The structure of the metal support frame is as follows: Figure 2 As shown, it also has a structure that is narrower at the top and wider at the bottom, with fixing rings at both the top and bottom. In order to fix the support frame into the brick body at the same time during the forming of the duct, a special tooling was developed. Summary of the Invention
[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a tooling for checker bricks in the heat storage chamber of a glass kiln. This tooling consists of two parts. When forming the channel, the metal support frame is fixed, which makes it convenient to fix the metal support frame in it during molding. It is easy to operate and has a good positioning effect.
[0004] To address the existing technical problems, this utility model discloses a tooling for checker bricks in the heat storage chamber of a glass kiln, comprising a fixed cylinder and a fixed clamp. The fixed clamp is fitted inside the fixed cylinder, which is a hollow structure that is narrower at the top and wider at the bottom. Fixed holes are spaced apart at the bottom of the fixed cylinder. The fixed clamp includes a vertical clamping rod, with a horizontal clamping claw at the end of the clamping rod. The clamping claw has a downwardly recessed fixing groove, and the fixing grooves on each clamping claw are at the same circumferential position. The clamping claws of the fixed clamp extend outward and retract inward from the fixing holes of the fixed cylinder.
[0005] Preferably, four fixing holes are provided at the bottom of the fixing cylinder, with the spacing between two adjacent fixing holes being consistent.
[0006] Preferably, the fixing clamp is provided with 4 clamping rods, and the fixing clamp has a flared opening structure, and the distance between the ends is greater than the distance between the top ends.
[0007] Preferably, the diameter of the fixing hole is 3-6 mm.
[0008] Preferably, the diameter of the gripper is 2-3 mm.
[0009] Preferably, the depth of the fixing groove on the gripper is 2-4mm, and the width of the fixing groove is 3-8mm.
[0010] Preferably, a handle is provided on the fixing clamp.
[0011] Preferably, the fixed cylinder is provided with multiple outwardly protruding ribs.
[0012] Preferably, the fixing groove is located in the middle of the gripper.
[0013] The beneficial effects of this utility model are as follows: The outer wall shape of the fixture's fixing cylinder is consistent with the inner wall shape of the channel, thus forming the channel. A metal support frame is provided on the outside of the channel, and there is a certain distance between the metal support frame and the channel. The fixing cylinder part of the fixture is a hollow cylindrical structure that is narrower at the top and wider at the bottom, and its outer wall shape is completely consistent with the shape and structure of the inner wall of the channel. After it is placed in the mold and the raw material is placed on it, the channel structure is formed. The fixing clamp part of the fixture extends from the fixing hole at the bottom of the fixing cylinder. The fixing groove of the clamp part holds the lower fixing ring of the metal support frame, which plays a supporting role and facilitates fixing the metal support frame in the clay blank during the initial molding. Since the diameter of the clamping claw and the fixing hole is relatively small, which is not much larger than the diameter of the raw material particles, the raw material particles will not diffuse too much into the fixing cylinder from the fixing hole during molding, which does not hinder production. After molding, the fixing clamp is squeezed inward, so that the clamping claw retracts into the fixing cylinder from the fixing hole and is demolded along with the fixing cylinder. This tooling is easy to operate and can fix the metal support frame in the brickwork. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.
[0026] like Figure 1 and Figure 2 As shown, the channel 2 of the checker brick body 1 used at the bottom of the heat storage chamber has an inverted conical structure that is narrow at the top and wide at the bottom. A metal support frame 3 with the same inverted conical structure is provided on the outside of the channel 2. The metal support frame 3 can significantly improve the support force of the bottom checker brick and prevent the bottom checker brick from collapsing and being damaged due to the weight of the upper brick body 1.
[0027] Example 1: As Figure 3-6 As shown, a tooling for checker bricks in the regenerator chamber of a glass kiln includes a fixing cylinder 4 and a fixing clamp 5. The fixing clamp 5 is fitted inside the fixing cylinder 4. The fixing cylinder 4 is a hollow structure that is narrow at the top and wide at the bottom. Fixing holes 6 are provided at intervals at the bottom of the fixing cylinder 4. The fixing clamp 5 includes a vertical clamping rod 51. A horizontal clamping claw 52 is provided at the end of the clamping rod 51. A downwardly recessed fixing groove 53 is provided on the clamping claw 52. The fixing grooves 53 on each clamping claw 52 are at the same circumferential position. The clamping claws 52 of the fixing clamp 5 extend outward and retract inward from the fixing holes 6 of the fixing cylinder 4.
[0028] like Figure 7 and Figure 8 As shown in this application, the fixed cylinder 4 forms the channel 2 structure, while the fixed clamp 5 supports the metal support frame 3. The two are movably connected. The fixed clamp 5 is placed inside the fixed cylinder 4. Since the fixed clamp 5 has its own telescopic clamping function, it can telescopically move inside the fixed cylinder 4. In its natural state, the jaws 52 of the fixed clamp 5 extend from the fixing hole 6 of the fixed cylinder 4 to support the metal support frame 3. When the clamping rod 51 is squeezed, the jaws 52 retract from the fixing hole 6 and retract into the fixed cylinder 4. By rotating the fixed clamp 5, the jaws 52 are misaligned with the fixing hole 6, and the jaws 52 press against the inner wall of the fixed cylinder 4, thus realizing the subsequent demolding operation.
[0029] In this embodiment, four fixing holes 6 are provided at the bottom of the fixing cylinder 4, with equal spacing between adjacent fixing holes 6. Four clamping rods 51 are provided on the fixing clamp 5, which has a flared opening structure, and the distance between the ends is greater than the distance between the tops. Obviously, the number and position of the fixing holes 6 and clamping rods 51 can be changed according to the actual situation. In order to enable the clamping rods 51 to extend and retract smoothly from the fixing holes 6, the positions of the fixing holes 6 and the clamping rods 51 correspond one-to-one and are adapted in size.
[0030] In actual production, the diameter of the fixing hole 6 is 3-6mm, the diameter of the gripper 52 is 2-3mm, the depth of the fixing groove 53 on the gripper 52 is 2-4mm, and the width of the fixing groove 53 is 3-8mm. While ensuring the gripper 52 can extend and retract smoothly, the diameter of the fixing hole 6 is minimized to avoid large pores formed by the gripper 52 penetrating deep into the brick 1, and also to prevent excessive material loss from the fixing hole 6 during molding, which would affect demolding. Practice has proven that this parameter setting does not cause the aforementioned problems, because the diameter of the raw material particles is about 1mm, and only a small amount of particles entering the fixing hole 6 will be blocked and compacted, preventing further particle entry. To facilitate demolding, the gripper 52 can also be designed to gradually taper outwards from the fixing cylinder 4, resulting in less resistance when the gripper 52 retracts.
[0031] To facilitate carrying the tooling, a handle 7 is provided on the fixing clamp 5; and according to the distance between the channel 2 and the metal support frame 3, the fixing groove 53 is set in the middle of the clamp 52, and the distance between the fixing groove 53 and the fixing cylinder 4 is the same as the distance between the metal support frame 3 and the channel 2.
[0032] The tooling involved in this application employs a secondary pressing method. First, the tooling is placed at the designated position in the mold. Then, the clamping rod 51 of the fixing clamp 5 extends from the fixing hole 6, and the metal support frame 3 is placed on the fixing groove 53. After assembly, raw material is poured into the mold for pre-forming. During pre-forming, the height of the raw material is slightly lower than the top of the fixing cylinder 4, firstly to securely fix the metal support frame 3 inside the brick body 1. After pre-forming, the fixing clamp 5 is tightened, and the clamping claw 52 is slowly extended from the fixing hole 6. More raw material is added to the surface of the pre-formed blank, avoiding the inside of the fixing cylinder 4, or a cylindrical brick blank is inserted into the fixing cylinder 4 to prevent raw material from entering the inside of the fixing cylinder 4. Pressure is continued for forming. During pre-forming, the gaps left by the retraction of the clamping claw 52 are compacted until forming is complete.
[0033] Example 2: Figure 9As shown, when there is a flow channel in the hole 2 of some brick body 1, multiple outward protruding strips 8 need to be set on the fixed cylinder 4. After the molding is completed, the part of the strip 8 forms a recessed flow channel corresponding to the position of the brick body 1, which can guide the airflow direction and achieve uniform air distribution.
[0034] Since the quantity of this type of brick is relatively small, the use of this tooling fully meets the production and usage requirements, greatly improving the precision of the brick and reducing the difficulty of subsequent processing.
[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
