Description

Technical Field

[0001] This utility model relates to the technical field of heat treatment and shaping equipment, and in particular to a syringe heat treatment and shaping equipment. Background Technology

[0002] The cylinder of a circular knitting machine is the core component of a circular weft knitting machine. As the base of the knitting needles, its diameter, machine size, and number of rows directly affect the fabric quality and production efficiency.

[0003] The heat treatment and shaping equipment for large circular knitting machine syringes includes quenching equipment, low-temperature tempering equipment, and vacuum heat treatment equipment. Among them, the low-temperature tempering equipment for large circular knitting machine syringes is mainly used to eliminate quenching stress through precise temperature control, while maintaining the high hardness and wear resistance of the syringes and ensuring their long-term stable operation.

[0004] There are three methods for cooling in low-temperature tempering equipment: natural cooling, wind power, and heat exchange with oil or water. The first two methods have poor cooling efficiency and can easily cause residues in the low-temperature tempering equipment to adhere to the large circular knitting machine syringe. Heat exchange with oil or water involves inputting oil or water through a straight pipe, which absorbs heat after passing through the large circular knitting machine syringe. However, this method cannot provide rapid cooling from all directions for the annular large circular knitting machine syringe. Utility Model Content

The inner wall of the low-temperature tempering chamber 11 is provided with at least one syringe-specific annular cooling component 12, which exchanges heat with oil or water in a serpentine circulation to achieve cooling. A cooling impeller 13 is rotatably provided on the top surface of the low-temperature tempering chamber 11.

[0022] The furnace cover 2 is connected to the low-temperature tempering furnace 1 by a hinge.

[0023] In one embodiment, in order to achieve efficient cooling for the syringe, the syringe-specific annular cooling assembly 12 includes a positioning ring 121 fixedly disposed on the inner wall of the low-temperature tempering chamber 11, a plurality of positioning shafts 122 arranged in a serpentine pattern on the inner circle of the positioning ring 121, and cooling pipes 123 wrapped around the plurality of positioning shafts 122.

[0024] In one embodiment, in order to perform heat exchange, the syringe-specific annular cooling assembly 12 further includes an oil pump located on the outer wall of the low-temperature tempering furnace 1 and connected to the output end of the cooling pipe 123, and an oil cooler located on the outer wall of the low-temperature tempering furnace 1 and connected to the input end of the cooling pipe 123. The output end of the oil pump is connected to the input end of the oil cooler through a pipe.

[0025] During operation, the hot oil or hot water that absorbs the heat from the syringe in the cooling pipe 123 is extracted by the oil pump and then fed into the oil cooler for cooling. The oil cooler then feeds the cooled oil or water back into the cooling pipe 123, and the cooling is carried out in a cycle.

[0026] In one embodiment, in order to connect and position the cooling pipe 123, the outer wall of the positioning shaft 122 is provided with an annular groove that is adapted to the cooling pipe 123.

[0027] In one embodiment, in order to drive the cooling impeller 13 to rotate for wind-powered cooling, the cooling impeller 13 is connected to the output terminal of the cooling motor 21.

[0028] In one embodiment, for ease of disassembly and maintenance, the cooling pipe 123 includes several arc-shaped pipes 1231 and several straight pipes 1232.
