Rail spike production process
Processing process
Prepare raw materials
Select suitable metal materials as raw materials, such as high-quality steel, to ensure the strength and durability of the spike.
Conduct preliminary inspection of raw materials to ensure material quality meets production requirements.
Blanking
A shear or punch is used to cut the raw material into a predetermined length of blank, the preliminary shape of the spike.
Heating
The billet is heated to the appropriate temperature to improve its plasticity and reduce deformation resistance to prepare for subsequent forging.
The heating temperature and time should be strictly controlled to avoid the degradation of material properties caused by overheating or overburning.
Pre-forging and Forming
The heated blank is put into the pre-forging die for preliminary forging and forming.
The shape and size of the preforging die are designed according to the final shape of the spike to ensure that the blank can gradually approach the final shape during the forging process.
Final-forging and Forming
The pre-forged blank is put into the final forging die for final forging and forming.
Under the action of a press or punch, the blank is forged into spikes of a specific shape and size. In this step, the head and rod of the spike are precisely shaped.
Follow-up treatment
The forged spike is cooled to stabilize its structure and properties.
Carry out the necessary surface treatment, such as removing burrs, polishing, etc., to improve the appearance quality and corrosion resistance of the spike.
Quality inspection of spikes, including dimensional inspection, hardness testing, etc., to ensure that they comply with relevant standards and requirements.
