Abstract
The invention discloses a temperature-controlled cooling method of an splitting connecting rod, which comprises the following steps of: (A) putting the forged connecting rod with the temperature of above 850 DEG C to a cooling device provided with an axial flow fan, for rapid cooling; and (B) when the connecting rod is cooled to 600+/-50 DEG C, putting the connecting rod into an iron box for cooing in pile, so that the connecting rod is cooled to room temperature. According to the temperature-controlled cooling method of the splitting connecting rod, the production cost can be reduced at the same time of meeting technical requirements.
Description
Technical field
The present invention relates to the forging field, relate in particular to a kind of temperature control cooling means of fractured connecting rod.
Background technology
The material behavior of fractured connecting rod has determined product needing after the forging from being quickly cooled to 600 ℃ more than 850 ℃; Be incubated processing subsequently; In the prior art, the temperature control cooling means that people usually adopt is that leading portion adopts blower fan to the workpiece cooling of drying, and back segment use heating wire adds heat-preservation cotton and is incubated processing; But the defective of this kind temperature control cooling means is: production cost is higher.
Summary of the invention
Technical problem to be solved by this invention is: the temperature control cooling means that a kind of fractured connecting rod that can reduce production costs is provided.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of temperature control cooling means of fractured connecting rod the steps include: A) temperature that will forge puts into the cooling device that has axial flow blower at the connecting rod more than 850 ℃ and carries out fast cooling; B) when connecting rod is cooled to 600 ± 50 ℃, connecting rod is put into the iron case carry out cooling in heap, thereby make connecting rod be cooled to normal temperature.
The invention has the beneficial effects as follows:, when satisfying specification requirement, can reduce production costs through adopting above-mentioned temperature control cooling means.
The specific embodiment
A kind of temperature control cooling means of fractured connecting rod the steps include: A) temperature that will forge puts into the cooling device that has axial flow blower at the connecting rod more than 850 ℃ and carries out fast cooling; B) when connecting rod is cooled to 600 ± 50 ℃, connecting rod is put into the iron case carry out cooling in heap, thereby make connecting rod be cooled to normal temperature.Through adopting above-mentioned temperature control cooling means, when satisfying specification requirement, can reduce production costs.
Said cooling device comprises: frame, be installed on the frame two ends sprocket wheel, be used for drive sprocket buncher, be installed on frame top axial flow blower, be installed on switch board on the frame, be installed on frame one end the inlet temperature measurer, be installed on the outlet temperature measurer of the frame other end; Be arranged with conveyer belt on the said sprocket wheel; Said conveyer belt is horizontally through frame; Said inlet temperature measurer and outlet temperature measurer all are arranged at the top of conveyer belt, and said switch board is provided with inlet temperature display list, outlet temperature display list and control button.Said control button comprises first control button of Control Shaft flow fan switch, second control button of control buncher switch and the 3rd control button of control buncher rotating speed.During cooling device work, at first start second control button, thereby the control buncher starts; Buncher starts the drive sprocket rotation, thereby makes the conveyer belt operation, is positioned on the conveyer belt forging good connecting rod; By way of frame, the axial flow blower of said frame top is lowered the temperature to the connecting rod on the conveyer belt, and said inlet temperature measurer can record the temperature of conveyer belt porch; This inlet temperature shows through the inlet temperature display list, thereby is convenient for people to observe; Said outlet temperature measurer can record the temperature in conveyer belt exit; This outlet temperature shows through the outlet temperature display list; Thereby be convenient for people to observe, when it is found that outlet temperature is too high or too low, can regulate the rotating speed of buncher through regulating the 3rd control button; And then the cool time of control workpiece, finally reach the purpose of controlling outlet temperature.
