Description

Technical Field

[0001] The utility model relates to the technical field of pressing devices, in particular to a pressing device for the production of long-distance engineering plastic drag chains. Background Technique

[0002] A drag chain, also known as a cable protection drag chain, is a device that binds cables or wires or pneumatic hoses and hydraulic hoses to facilitate their rotation and movement. The drag chain is applied to occasions with reciprocating motion. When producing a drag chain, a pressing device for the production of long-distance engineering plastic drag chains is required.

[0003] According to the description in a pressing device for drag chain production (authorization announcement number: CN 220946808U) disclosed on the patent network, "The utility model relates to a pressing device for drag chain production, including a support base. A fixed rod is fixedly connected to the inner side of the support base. Two sliding blocks are movably connected to the outer side of the fixed rod. Annular springs are fixedly connected to the outer sides of the two sliding blocks. Movable support blocks are fixedly connected to the tops of the two sliding blocks. Buffer support blocks are movably connected to the tops of the two movable support blocks. Movable square plates are fixedly connected to the tops of the two buffer support blocks. A pressing die is movably connected to the top of the movable square plate. Telescopic springs are fixedly connected to the tops of the two buffer support blocks. A support column is fixedly connected to the top of the support base. A fixed top plate is fixedly connected to the top end of the support column. This pressing device for drag chain production is convenient to use, achieves the purpose of buffering and shock absorption of the pressing device, avoids damage to the pressing device due to excessive impact when pressing the drag chain for a long time, and improves the service life of the pressing device."

However, in actual use, after the drag chain is processed, it needs to be taken out of the pressing die manually. And the temperature of the die just after pressing is relatively high, which is easy to cause burns when taking it. Taking it after cooling is less efficient. Therefore, it is necessary to improve a pressing device for the production of long-distance engineering plastic drag chains to solve the above problems. Content of the Utility Model

The external thread of the threaded rod 713 is installed with a threaded sleeve 714, and the bottom of the threaded sleeve 714 is fixedly installed with a lifting plate 715. The top of the lifting plate 715 is fixedly installed with a fixing column 716, and a fixing bolt A6 is threadedly installed inside the platform 1. A sliding column 717 is slidably installed inside the fixed column 716, which slides inside the fixed column 716 to limit the movement of the lifting plate 715.

[0031] Furthermore, the top of the sliding column 717 is fixedly installed on the fixing frame 711 , and the threaded rod 713 is rotatably installed inside the fixing frame 711 to drive the threaded sleeve 714 to move up and down.

[0032] Furthermore, the unloading component 72 includes a motor B721, which is fixedly installed on the back of the platform 1. A gear A722 is fixedly installed on the output end of the motor B721, and a rotating shaft A723 is fixedly installed on the front of the gear A722. There are two rotating shafts A723, and a rotating plate 724 is fixedly installed on the outside of the two rotating shafts A723.
