Description

Technical Field

[0001] The utility model relates to the technical field of material transfer forks, in particular to a material transfer fork for a rotary heat treatment furnace. Background Art

[0002] The rotary heat treatment furnace adopts the form of a manipulator equipped with a transfer fork to carry out material feeding and taking out of the furnace and transfer of workpieces outside the furnace.

[0003] The robot has many movements and a tight rhythm. The workpiece needs to be precisely positioned on the transfer fork, and workpiece offset or dropout is not allowed. Therefore, the stability of the structure and function of the transfer fork is a key factor in ensuring the normal operation of the heat treatment process. The design of the fork is different for different workpiece sizes, but the anti-slip property must be considered.

[0004] In the past, material forks were mostly welded as a whole. If damaged, they needed to be replaced as a whole. The anti-skid structure was mostly processed into a serrated shape on the fork tines, or an anti-skid net was welded on the fork tines. The anti-skid effect was not ideal and the wear was irreversible.

[0005] For this reason, we urgently need to provide a kind of transfer material fork for rotary heat treatment furnace. Utility Model Content

[0006] The purpose of the utility model is to provide a material transfer fork for a rotary heat treatment furnace, so as to solve the problem proposed in the above background technology that material forks in the past are mostly of one-piece welded type, and if damaged, they need to be replaced as a whole, and the anti-skid structure is mostly processed in a serrated shape on the fork teeth, or an anti-skid net is welded on the fork teeth, etc., and the anti-skid effect is not ideal, and there is an irreversible problem after wear.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a material transfer fork for a rotary heat treatment furnace, comprising a robot connecting plate, a transfer device is arranged on the left side of the robot connecting plate, and the transfer device comprises a mounting unit and an anti-slip unit.

[0008] The mounting unit is arranged on the left side of the robot connecting plate, and the anti-slip unit is arranged inside the mounting unit.

[0009] The installation unit includes a vertical connecting plate, a reinforcing cover plate, a fixing part, a fork tine and a processing furnace. The vertical connecting plate is fixedly installed on the left side of the robot connecting plate by a hexagonal bolt, the reinforcing cover plate is fixedly installed on the top of the vertical connecting plate by a hexagonal bolt, the fixing part is fixedly installed on the left side of the vertical connecting plate by a hexagonal bolt, the fork tine is fixedly installed on the left side of the fixing part by a hexagonal bolt, and the processing furnace is installed on the top of the fork tine.

[0010] Preferably, the anti-slip unit comprises a saw blade and a pressure plate, wherein the saw blades are two in number and are installed at the front and rear sides of the fork tine, and the pressure plate is installed inside the fork tine and located between the front and rear fork tine.

[0011] Preferably, there are multiple fork tines, and all are fixed on the left side of the fixing member by hexagonal bolts. Each fork tine is independent of each other. If a fork tine is deformed, the deformed fork tine can be replaced without having to remake the entire material fork.

[0012] Preferably, the robot connecting plate is connected to the robot via hexagonal bolts, and the various components of the material fork are connected via hexagonal bolts. Bolt connection is more convenient for component replacement and simplifies manufacturing than welding.

[0013] Preferably, a mounting groove is opened inside the fork tine, and the saw blade and the pressure plate are installed inside the mounting groove. The pressure plate squeezes the sides of the front and rear saw blades so that the saw blades are always in contact with the inner wall of the mounting groove, thereby avoiding shaking of the saw blades and improving the stability of the transfer of the processing furnace.

[0014] Preferably, mounting holes are provided on the front and rear sides of the fork tine, and bolts are passed through the mounting holes to fix the saw blade and the pressure plate in the fork tine, so as to facilitate the fastening of the saw blade and the pressure plate to the fork tine and the replacement of the saw blade.

[0015] Preferably, the front and rear saw blades are installed with inverse serrations, which has a good anti-slip effect on the transfer of the processing furnace.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The transfer material fork for the rotary heat treatment furnace is provided with a mounting unit. Since each fork tine is connected to a fixing member by a hexagonal bolt, each fork tine is independent of each other. If the fork tine is deformed, the deformed fork tine can be replaced without having to remake the entire material fork, thereby simplifying the production and facilitating replacement, saving materials, and solving the problem in the background technology that most material forks are welded in one piece and need to be replaced as a whole if damaged.

[0018] 2. The material transfer fork for the rotary heat treatment furnace is provided with an anti-skid unit, and in the process of transferring the rotary heat treatment furnace, the two saw blades are used in a unique installation method with reverse sawteeth to prevent the treatment furnace from skidding. At the same time, since the saw blade and the pressure plate are fastened to the fork teeth by bolts, when the saw blade is damaged, it is convenient to replace the saw blade by removing the bolts, thereby solving the problem of unsatisfactory anti-skid effect and irreversible wear mentioned in the background technology.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0026] Embodiment 1: A material transfer fork for a rotary heat treatment furnace includes a robot connecting plate 1, which is connected to the robot by hexagonal bolts, and the various components of the material fork are connected by hexagonal bolts. The bolt connection method is more convenient for component replacement than welding, and simplifies production.

[0029] Embodiment 2: On the basis of embodiment 1: the anti-skid unit includes a saw blade 301 and a pressure plate 302. There are two saw blades 301 and they are installed on the front and rear sides of the fork tine 204. The saw blade 301 has an anti-skid effect on the transfer of the rotary heat treatment furnace. The pressure plate 302 is installed inside the fork tine 204 and is located between the front and rear fork tine 204. The fork tine 204 has a mounting groove. The saw blade 301 and the pressure plate 302 are installed inside the mounting groove. The pressure plate 302 squeezes the sides of the front and rear saw blades 301 so that the saw blade 301 is always in contact with the inner wall of the mounting groove, thereby preventing the saw blade 301 from shaking and improving the stability of the transfer of the treatment furnace 205. The fork tine 204 has mounting holes on the front and rear sides. Bolts penetrate the mounting holes to fix the saw blade 301 and the pressure plate 302 in the fork tine 204, which is convenient for fastening the saw blade 301 and the pressure plate 302 to the fork tine 204 and convenient for replacing the saw blade 301.

[0031] When in use, the robot connecting plate 1 is connected to the robot through the hexagonal bolts, and then the processing furnace 205 is placed on the top of the fork teeth 204 to transfer the processing furnace 205. During the transfer process, the unique installation method of the two saw blades 301 with reverse teeth has an anti-slip effect on the processing furnace 205, thereby improving the stability of the transfer. Since each fork tooth 204 is connected to the fixing part 203 through a hexagonal bolt, each fork tooth 204 is independent of each other. If the fork tooth 204 is deformed, the deformed fork tooth 204 can be replaced without remaking the entire material fork. Since the saw blade 301 and the pressure plate 302 are fastened to the fork tooth 204 by bolts, when the saw blade 301 is damaged, it is also convenient to replace the saw blade 301 by removing the bolts.
