[0002] Thermosetting polyurethane elastomer, abbreviated as PU, is a new type of synthetic material that is between plastic and rubber. It is formed by the reaction of polymer polyol and isocyanate, through chain extension and cross-linking. According to the different main chain structures of polyurethane elastomer, it is divided into two types: polyether type and polyester type.

[0003] For small-diameter urethane round rods that need to be cut, traditional processing techniques are difficult to use. Most of the time, utility blades are used, and cutting is done by hand. As a result, due to the limitations of traditional processing methods, the height of the cuts is inconsistent, the cut surface is uneven, and the blades can easily cut the hands during processing.

By using a bar fixing mechanism, the workpiece can be quickly clamped, saving clamping and processing time and improving processing quality. Furthermore, by adjusting according to the end of the bar, the smallest end of the bar can be cut. The use of the cutting mechanism can make the end face of the processed bar relatively flat and of equal height, improving the yield of the workpiece. During processing, the cutting blade is far from the operator's hand, avoiding hand injuries.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a mechanism for rapidly cutting urethane round bars, comprising:

[0025] A base 1 with mounting bolts 2 is provided at each of the four corners of the top;

[0026] The positioning mechanism has two sets, both of which are located on the top of the base 1;

[0027] A glue rod fixing mechanism, mounted on one of the positioning mechanisms, is used for positioning the glue rod during the cutting process. The glue rod fixing mechanism includes a top component, a glue rod fixing block 12, and a glue rod hole 6. The glue rod fixing block 12 is mounted on one of the positioning mechanisms, the glue rod hole 6 is formed within the glue rod fixing block 12, and the top component is mounted on the glue rod fixing block 12.

[0028] The cutting mechanism is mounted on another set of positioning mechanisms and is used to cut the glue stick. The cutting mechanism includes a mounting component, a rotating component, a cutting blade 14 and a cutting groove 11. The mounting component is mounted on another set of positioning mechanisms, the rotating component is mounted on the mounting component, the cutting groove 11 is opened on the glue stick fixing block 12, the cutting blade 14 is mounted on the rotating component, and the cutting blade 14 is connected to the cutting groove 11.

[0029] In this implementation scheme: the overall weight of the device is relatively small, and it can be fixed to the workbench with four mounting bolts 2 on the base 1 for easy use. The size of the glue rod hole 6 is slightly larger than that of the urethane glue rod, making it easy to insert the glue rod. The cutting blade 14 and the cutting groove 11 are aligned one by one, so that the cutting blade 14 can complete the cutting of the glue rod and ensure its use. The cutting blade 14 and the cutting groove 11 are positioned opposite each other, so that the cutting blade 14 enters the cutting groove 11 to cut the glue rod. The cutting blade 14 needs to be replaced according to the degree of wear.

[0030] Specifically, each positioning mechanism includes a fixing bolt 5 and two limiting rods 4. The two limiting rods 4 are installed on the base 1 and are connected to the bottom of the glue rod fixing block 12. The fixing bolt 5 is located on the base 1 and is threaded to the center of the bottom of the glue rod fixing block 12.

[0031] In this embodiment, the fixing bolt 5 and the two limiting rods 4 facilitate the installation of the glue rod fixing block 12 and the cutting mechanism on the base 1, enabling their use and ensuring their positions to avoid displacement.

[0032] Specifically, the top position component includes a telescopic assembly and a top position block 8. One end of the rubber rod fixing block 12 is threadedly connected to a top position positioning bolt 3. The top position block 8 is rotatably connected to the top position positioning bolt 3, and the telescopic assembly is located on the top position block 8.

[0033] In this embodiment: the top block 8 controls the sealing of the glue rod hole 6 to achieve length adjustment control of the urethane cutting, and the top positioning bolt 3 controls the rotation of the top block 8 to facilitate the removal of the cut glue rod.

[0034] Specifically, the telescopic component is a top bolt 10, which is threaded to the top center of one side of the outer surface of the top block 8, and one end of the top bolt 10 extends into the glue rod hole 6.

[0035] In this embodiment, the top bolt 10 can extend into the glue rod hole 6 to complete the cutting of a shorter glue rod.

[0036] Specifically, the mounting components include a rotating fixing block 9 and a rotating mounting groove 7. The rotating mounting groove 7 is located on one side of the top of the base 1 and is opened inside one side of the rotating fixing block 9.

[0037] In this embodiment, the rotating fixing block 9 and the rotating mounting groove 7 are used to install the rotating component.

[0038] Specifically, the rotating component includes a rotating shaft 16, a blade mounting block 15, and a pressing handle 13. The rotating shaft 16 is rotatably connected to the top of the rotating mounting groove 7, one end of the blade mounting block 15 is rotatably connected to the rotating shaft 16, and the pressing handle 13 is fixedly connected to one end of the blade mounting block 15.

[0039] In this embodiment: the rotating shaft 16 facilitates the installation and removal of the blade mounting block 15 in the rotating mounting groove 7, and the long pressing handle 13 enables cutting with a small force. The cutting blade 14 is installed in the blade mounting block 15 and can be replaced. The position of the blade mounting block 15 and the rotating fixing block 9 needs to be precisely machined to ensure the size of the processed urethane.

[0040] In use, place the glue rod to be cut into the glue rod hole 6. Adjust the relative position of the top positioning bolt 10 in the top positioning block 8 according to the required cutting length of the glue rod end to position the glue rod. Rotate the pressing handle 13 to make the blade mounting block 15 rotate in the rotating mounting groove 7, and control the cutting blade 14 to press down into the cutting groove 11 to complete the cutting of the glue rod. After cutting, lift the pressing handle 13 to make the cutting blade 14 disengage from the cutting groove 11. Rotate the top positioning block 8 through the top positioning bolt 3 to push the glue rod and control the cut glue rod to exit the glue rod hole 6. Then, pull out the remaining glue rod.

[0041] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.
