The invention discloses a
temperature control precision improving device of a
forging mechanical press. The device comprises a
crankshaft bearing bush and eccentric body bush
temperature control device, and further comprises a sliding block guide rail
temperature control device and a ball head temperature control device; the sliding block guide rail temperature control device comprises temperaturecontrol channels arranged at the front left side, the front right side, the rear left side and the rear right side of a sliding block, the temperature control channels are arranged at the position, provided with a guide rail plate, in the sliding block, and each temperature
control channel is provided with an air inlet and an air outlet; and the ball head temperature control device comprises a wear-resistant
copper pad arranged in a ball head seat, a ball head screw rod doses relative movement in the wear-resistant
copper pad, the wear-resistant
copper pad is connected with the ball head seatthrough a screw, a seal ring is arranged between the wear-resistant copper pad and the ball head seat, and a spiral temperature
control channel is arranged on the fitting surface of the ball head seat and the interior of wear-resistant copper pad. According to the device, the temperature of the guide rail plate is controlled to be stable, the guide rail plate can not be expanded due to
heating temperature rise, the precision of a sliding block guide rail is kept stable, the stability of the ball head screw rod and the ball head seat is guaranteed, and the overall precision, production efficiency and machined product quality of the
forging mechanical press are improved.
