Description

Technical Field

[0001] This utility model belongs to the technical field of pressing frame for forming ceramic fiber heaters, and specifically relates to a pressing frame for forming ceramic fiber heaters. Background Technology

[0002] The ceramic fiber heater is mainly formed using wet vacuum forming technology. The core of this process is to apply uniform pressure through a specially designed press while creating a vacuum environment to ensure that the ceramic fiber material can be tightly bonded and achieve precise forming. The advantage of wet vacuum forming technology is that it can effectively control the distribution and density of the material, thereby improving the overall performance and consistency of the finished product.

[0003] Currently, domestic manufacturers of metal resistance wires lack specialized tools during processing and shaping, leading to several problems in the production of ceramic fiber heaters. These problems include insufficient flatness, resulting in different coils of the resistance wire not being on the same horizontal plane when placed in the mold and integrated with the ceramic fiber. Furthermore, the depth of the resistance wire embedded in the ceramic fiber varies, causing uneven heat radiation within the furnace and affecting temperature uniformity. Additionally, uneven spacing between the two coils of the resistance wire also impacts the uniform temperature distribution within the resistance furnace. Utility Model Content

[0004] The purpose of this utility model is to provide a pressing frame for forming ceramic fiber heaters, in order to solve the problems mentioned in the background art. Currently, domestic manufacturers lack professional tools in the processing and shaping of metal resistance wires, resulting in some problems in the production of ceramic fiber heaters. These problems include insufficient flatness, different coils of the resistance wire not being on the same horizontal plane when placed in the mold and formed into a single unit with the ceramic fiber, uneven depth of the resistance wire when embedded in the ceramic fiber, uneven heat radiation in the furnace, affecting the uniformity of the furnace temperature, or uneven spacing between the two coils of the resistance wire, which also affects the uniform distribution of temperature in the resistance furnace.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pressing frame for forming a ceramic fiber heater, comprising a square slotted aluminum profile vertical section, a square slotted aluminum profile horizontal section installed at the rear end of the square slotted aluminum profile vertical section, corner brackets installed at the left and right ends of the square slotted aluminum profile horizontal section, a slot provided at the rear end of the square slotted aluminum profile vertical section, an L-shaped locking post fixed at the front end of the corner bracket being engaged in the slot, a plurality of V-shaped nylon blocks installed at the front end of the square slotted aluminum profile vertical section, a set screw provided at the front end of the V-shaped nylon blocks, and a bolt provided at the rear end of the square slotted aluminum profile vertical section.

[0006] Preferably, the square slotted aluminum profile vertical section is connected to another square slotted aluminum profile vertical section via a straight connector at one end.

[0007] Preferably, the vertical and horizontal sections of the square slotted aluminum profile are installed at a right angle.

[0008] Preferably, the corner bracket is installed by using T-nuts to connect the vertical and horizontal sections of the square slotted aluminum profile.

[0009] Preferably, multiple corner brackets are installed at both ends of the square slotted aluminum profile crossbar.

[0010] Preferably, multiple V-shaped nylon blocks are installed at the front end of the vertical section of the square slotted aluminum profile.

[0011] Preferably, when the corner bracket is installed with the horizontal and vertical sections of the square slotted aluminum profile, the L-shaped locking post is locked in the slot.

[0012] Preferably, the length at the upper end of the slot is greater than the length of the L-shaped locking post.

[0013] Compared with the prior art, the present invention provides a pressing frame for forming ceramic fiber heaters, which has the following advantages:

[0014] To reduce defects in heated workpieces and lower customer costs, a pressing frame for forming ceramic fiber heaters has been invented. This device is simple to manufacture, requiring only the tightening and loosening of screws for assembly, and can be completed in about forty minutes. It is low-cost, essentially a one-time investment, and can be reused and reassembled in any configuration. The cost is less than 10% of the original, almost negligible. It boasts high precision, with the flatness and column spacing of the pressing frame controlled within two millimeters. This ensures that the resistance wires are completely flattened and the column spacing is uniformly controlled, resulting in a uniform temperature distribution when the heater is installed in the furnace. This significantly reduces the defect rate of heat-treated workpieces, and the resistance wires dissipate heat well, extending the heater's lifespan. Ultimately, this reduces customer costs and increases customer satisfaction.

[0015] A slot is provided at the upper end of the vertical section of the square slotted aluminum profile. When the corner bracket is installed with the vertical section of the square slotted aluminum profile, the L-shaped locking post that is fixed to the corner bracket is inserted into the slot and then moved to the inner position of the slot. This increases the stability when it is locked with a T-nut. Attached Figure Description
