Problems solved by technology

If the cracks are large, pressurization cannot save them, and they become waste products. After sintering, they will be selected and removed, but it is difficult to remove 100% saw blades containing cracks, which leaves hidden dangers to product quality.

Embodiment 1

[0022] A furnace-loading workbench for sintered saw blades comprises a workbench 1 for supporting saw blade moulds. The workbench 1 has a hole matched with a mandrel on the horizontal plane, and the diameter of the hole is slightly larger than the diameter of the mandrel. The mandrel passes through the hole in the horizontal plane of the workbench 1, and the mandrel can be lifted up and down freely in the hole. The saw blade positioning device is provided on the workbench 1, and the saw blade positioning device includes a vertical mandrel guide rail 2 for guiding the mandrel fixed on the workbench 1 and a step up from the bottom to the mandrel guide rail 2 close to the workbench 1. The rising mandrel ejector pin 3 is arranged on the mandrel bottom, and the diameter of the mandrel mandrel ejector pin 3 is preferably the same as that of the mandrel. The mandrel push rod 3 is connected with the stepping lifting device, and the stepping lifting device includes a ratchet bar 4, a d...

Embodiment 2

[0031] The main difference between Embodiment 2 and Embodiment 1 is that Embodiment 2 also includes a non-return mechanism and a travel baffle.

[0032] The workbench 1 is also provided with a non-return mechanism beside the ratchet bar 4, and the non-return mechanism is a horizontal positioning horizontal cylinder. One end of the positioning horizontal cylinder is provided with a friction block. The end of the friction block protrudes from the positioning horizontal cylinder and is in vertical contact with the side of the ratchet bar 4. The friction block prevents the ratchet bar 4 from falling by friction force. The other end of the friction block is provided with a spring and a screw connection. The screw plug in the positioning horizontal cylinder. The screw plug can change the elastic length of the spring to adjust the size of the static friction force of the friction block. One side of the lowering handle 5 corresponding to the ratchet rack 4 has a ratchet, the other si...

Abstract

The invention discloses a furnace loading workbench for sintered saw blades, which belongs to the technical field of auxiliary equipment for furnace loading of sintered saw blades. The device includes a vertical mandrel guide rail fixed on the workbench for guiding the mandrel and a mandrel ejector rod which is close to the mandrel guide rail and rises step by step from bottom to top, and the mandrel ejector rod is connected with the stepping lifting device , the present invention improves the life of the existing spacer, reduces the breakage of the sintered saw blade during pressurization, improves the quality of the sintered saw blade, reduces the labor intensity, reduces the working gap between the mandrel, the spacer and the matrix, and improves the production efficiency. efficiency.

Description

technical field [0001] The invention relates to furnace charging of sintered saw blades, in particular to a furnace charging workbench for sintered saw blades, which belongs to the technical field of auxiliary equipment for furnace charging of sintered saw blades. Background technique [0002] At present, the heat sources required in the production process of domestic diamond tools are resistance furnaces, pit furnaces, continuous furnaces, and bell furnaces. Use is more common. The sintering process is to install the pressed saw blades (commonly known as wool) in the spacer, and then stack them up along the axis of the saw blade. Every two pressed saw blades are separated by a spacer. The spacer is actually the final shape of the saw blade. The mold is generally made of graphite or heat-resistant steel and can be reused. The upper and lower pads are generally made of graphite. In order to make the positioning of saw blades and spacers in each stack accurate, positioning h...
