Forging machinery press temperature control accuracy improvement device

Abstract

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.

Description

Technical field: [0001] The invention relates to a device for improving the temperature control precision of a forging mechanical press. Background technique: [0002] With the rapid development of major engineering projects in my country's key industries such as automobiles, high-speed rail, military industry, machinery, and home appliances, the current forging industry market is increasing with the improvement of forging materials and mold quality, and the demand and output of precision forging parts are increasing. The unprecedented development opportunities for forging machinery and equipment have come, and at the same time, the precision requirements for forging machinery presses are also getting higher and higher. [0003] well known, such as Figure 1-2 As shown, the forging mechanical press can generally be divided into several parts from the structure, including the body 1, the crankshaft and the bearing bush 2, the ball screw 3, the ball seat 4, the transmission, th...

Problems solved by technology

[0007] In order to make up for the deficiencies in the prior art, the present invention provides a temperature control precision improving device for a forging mechanical press, which solves the problem that the temperature rise between the slider and the guide rail of the forging mechanical press causes the gap to become smaller and restricts the improvement of the precision of the press, and solves the problem of The temperature rise between the ball screw and the ball seat leads to a smaller gap, which restricts the improvement of the precision of the press, and improves the overall precision and product quality of the forging machinery press.
