Abstract
A cold squeeze method for machining the regulating screw bolt with hot-rolled circular steel without cutting includes blanking, annealing, grinding external circumference, turning two end faces, immersing in water-base high-molecular lubricating liquid, die squeezing, cold rolling to thread it, and blackening. Its advantages are low production cost and high mechanical strength.
Description
The present invention relates to a kind of metal extruding method, particularly adjust the cold extrusion of screw rod and do not have cutting working method.
The existing adjustment screw rod that is used on the jack, generally adopt metal cutting to process then cold-rolled thread or forge its top shape and screw thread roll before technology cylindrical, the substep processing technology of cold-rolled thread again.There is following shortcoming in this technology: waste of material, and technology cost height, production efficiency is low.
The purpose of this invention is to provide a kind of adjustment screw machining method with hot rolled circular steel cold extrusion non-cutting shaping, it can reduce process procedure, reduces production costs and improves and adjust screw rod mechanism intensity and simplify shaping of the multiple shape in top.
The present invention is achieved like this: a kind of adjustment screw machining method with hot rolled circular steel cold extrusion non-cutting shaping, the processing of employing following steps: woollen fracture becomes blank, blank is annealed, cylindrical grinding, car biend become workpiece, workpiece immerses water base high molecular lubricant stoste, after the taking-up workpiece sent into press extrusion modling in mould, remove the water base high molecular lubricant masking liquid of surface of the work, workpiece cold-rolled thread on wire rolling mill becomes to adjust screw rod, adjusts the screw surface blackout and makes finished product.
After the present invention adopts said method, reduced process procedure, owing to be no machining, raw material have been saved, reduced production cost, workpiece has been carried out cold extrusion improved the mechanical strength of adjusting screw rod, and can shape adjusting the multiple shape in screw rod top.
Below in conjunction with accompanying drawing the present invention is further described below.
Fig. 1 is the sketch of workpiece 1 of the present invention.
Fig. 2 is the sketch of workpiece 2 of the present invention.
Fig. 3 adjusts the sketch of screw rod 3 for the present invention.
Fig. 4 is a mould sketch of the present invention.
According to designing requirement fracture on blank cutter, blank carries out conventional annealing behind the fracture hot rolled circular steel in the present invention elder generation, and the blank cylindrical grinding is to remove oxide layer.With the front and rear end of blank at the lathe biend of getting on the bus, reach production engineering specifications and form workpiece 1, workpiece 1 was immersed in 100 ℃ of boiling water 20 minutes, take out natural air drying, make workpiece 1 temperature about 30 ℃, this workpiece is placed water base high molecular lubricant stoste, it is the product of 85102380.0 preparations that the water base high molecular lubricant adopts the patent No. again.Extrusion modling becomes workpiece 2 in the press die with sending into after the workpiece taking-up.Remove the water base high molecular lubricant masking liquid method on workpiece 2 surfaces: workpiece 2 is immersed 0
#In the diesel oil and stir, until recovering surperficial original state.Workpiece 2 is carried out cold-rolled thread on wire rolling mill, carry out conventional blackening at last and become to adjust screw rod 3.
The present invention becomes workpiece 1 behind car biend and cylindrical grinding after woollen fracture becomes blank 1, workpiece 1 size reaches production engineering specifications, and workpiece 1 diameter is φ
1When the mould of on press workpiece being packed into carries out cold extrusion, workpiece 1 part of stretching out counterdie 5 becomes the top of adjusting screw rod owing to hot rolled circular steel has plasticity when patrix 4 cold extrusions, its top shape depends on the intrinsic shape of patrix 4 pressure heads, originally the adjustment screw rod of packing in the cavity of counterdie 5 expands and slightly becomes designing requirement, and its diameter is φ
2Workpiece 2 is carried out cold-rolled thread become to adjust screw rod 3 on wire rolling mill, the diameter of thread of adjusting screw rod 3 is φ
