The invention discloses an equal-temperature hot drawing forming device and method for controlling wall thickness uniformity of a component, and relates to the field of equal-temperature hot drawing forming devices and methods by controlling the wall thickness uniformity of the component, which solves the technical problem that in an existing hot drawing technology method, bottom part reduction issevere, and thus blank deformation is nonuniform. The equal-temperature hot drawing forming device includes a hot forming press machine, a die and a gas cooler, wherein the die includes a template, afixing plate, an air inlet pipe, an air outlet pipe, a male die and a female die. The method includes the steps that 1, the die is mounted on the hot forming press machine; 2, heating is conducted, sheet materials are put into, heat insulation is conducted, cooling gas is introduced, drawing forming is conducted, and pressure maintaining is conducted; and 3, the die is opened and is cooled to a room temperature, and inspection and acceptance are conducted. According to the equal-temperature hot drawing forming device and method, circulating helium is introduced into a male die hollow structural cavity through an air passage of an upper male die to lower the temperature of the upper die, the degree of deformation of the contact part of the sheet materials and the upper male die is reduced,the thicknesses of the arc positions of the bottom parts of the sheet materials are increased, and uniform deformation of a formed part is achieved. The equal-temperature hot drawing forming device and method are used for preparing sheet material parts.
