Technical Field

[0001] The utility model relates to the technical field of polytetrafluoroethylene shaping devices, and specifically relates to a polytetrafluoroethylene shaping device that is convenient to use. Background Art

[0002] At present, polytetrafluoroethylene is a high molecular polymer prepared by polymerizing tetrafluoroethylene as a monomer, with the chemical formula (C2F4)n. It has excellent heat resistance and cold resistance and can be used for a long time at -180 to 260 °C. This material has the characteristics of being resistant to acids, alkalis, and various organic solvents and is almost insoluble in all solvents. At the same time, polytetrafluoroethylene has the characteristic of high temperature resistance, and its friction coefficient is extremely low. Therefore, in addition to being used as a lubricant, it has also become an ideal coating for the inner layer of easily cleanable water pipes. It is used in the electrical industry and is used as an insulating layer for power and signal lines, corrosion-resistant and wear-resistant materials in industries such as aerospace, aviation, electronics, instrumentation, and computers. It can be made into films, tube plates, rods, bearings, gaskets, valves, and lining for chemical pipelines, pipe fittings, and equipment containers.

The two sides of the operating platform 1 are symmetrically and penetratingly provided with sliding grooves 2. A sliding rod with both ends fixedly connected to the inner side walls of the sliding grooves 2 is arranged in the sliding grooves 2. Through the setting of the sliding rod, the stability of the driving cylinder driving the clamping plate 3 and the extended clamping plate 4 to displace is ensured. A driving cylinder is arranged on the bottom end surface of the operating platform 1. Connecting plates slidably connected to the sliding rod are arranged on the output ends on both sides of the driving cylinder. The top of the connecting plates extends to the outside of the sliding grooves 2 and is provided with a clamping plate 3 with a bottom end surface parallel to the operating platform 1. Guiding connection grooves 10 are symmetrically opened on both sides of the clamping plate 3. A guiding connection plate 15 is slidably connected in the guiding connection grooves 10. An extended clamping plate 4 integrally formed with the guiding connection plate 15 is arranged on one side of the guiding connection plate 15. A plurality of uniformly distributed reinforcing plates 6 are arranged between the extended clamping plate 4 and the clamping plate 3. Through the setting of the reinforcing plates 6, the connection strength and stability between the clamping plate 3 and the extended clamping plate 4 are further improved.

[0027] The working principle of the present utility model is as follows:

[0028] During use, the shaping die is placed between the two clamping plates 3 on the operating table 1. The staff measures the size of the shaping die and adjusts the extended clamping plates 4 on both sides of the clamping plate 3 until the sum of the lengths of the clamping plate 3 and the two extended clamping plates 4 is greater than the size of the shaping die. After adjustment, the connection bolt 7 is inserted into the communicated first connection holes 14 and second connection holes 12 for fixation, limiting and fixing the adjusted extended clamping plate 4. Finally, the driving cylinder is started to drive the two clamping plates 3 to move towards each other to clamp the shaping die. The structure of the present utility model is simple and convenient to use, which can ensure stable clamping and fixation of the shaping die, and can also fix and clamp shaping dies of various sizes, avoiding unstable clamping caused by too large a size of the shaping die, and greatly improving the applicability.
