Relatively thin, which solve conventional pumps Stator forces, heat dissipations and the non-uniform problems such as temperature is swollen.Compared with single-head screw pumps, bull is big
Discharge capacity iso-wall thickness progressive cavity pump discharge capacity is significantly increased, and since the wall thickness structures such as use, eccentricity reduce, avoids conventional screw pump
The case where stator rubber became uneven, substantially prolongs stator service life.
The Chinese patent that publication No. is CN101865129A disclose a kind of screw pump stator with equal wall thickness processing method and
Special push-pull device, key step include manufacture internal model, the coaxial welding mandrel in internal model；External mold is manufactured, into raw material steel pipe
It fills and applies lubricant and be sleeved on mandrel, mandrel and external mold are loaded on push-pull device；Internally, external mold heats；Startup pushes away
It draws equipment to push steel pipe Forward, squeezes out stator pump barrel；Alignment, sandblasting, injecting glue vulcanization.There are one branch for its special push-pull device
Plate is equipped with linear reciprocating mechanism in support plate side and connects track base by guide rail, clamping is connected in the support plate other side
Device is equipped with sliding rack and cylinder bracket on track base and is equipped with drawing oil cylinder between, is equipped on sliding rack outer
Mould.
But due to above-mentioned technics comparing complexity, in actual production, processing efficiency is relatively low, needs matching for interior outer mold
Conjunction could complete stator tube forming, and interior outer mold is not easy to fabricate, and will produce certain error, pass through interior external mold
Tool processing screw pump stator can so that mismachining tolerance is further bigger than normal, and the helical pitch and cavity error of metal stator cannot be controlled effectively
System, precision be not high.
Invention content
The first object of the present invention is to provide bull huge discharge screw pump stator with equal wall thickness and is manufactured equipment, can be compared with
Shorten the processing technology of stator well, and improves the machining accuracy of stator.
The present invention above-mentioned technical purpose technical scheme is that：
Bull huge discharge screw pump stator with equal wall thickness is manufactured equipment, including main feed mechanism, is located at the main feeding
The shaping mechanism of mechanism one end, and the auxiliary feed mechanism between the main feed mechanism and the shaping mechanism, it is described
Main feed mechanism includes hydraulic clamp feed clamp, and the driving relatively described shaping mechanism of hydraulic clamp feed clamp is reciprocal
The driving portion of movement, the shaping mechanism include hydraulic forming machine, the hydraulic forming machine and the hydraulic clamp feed clamp
And the driving portion is controlled by numerical control combined adjuster, the numerical control combined adjuster is a PLC control system.
By using above-mentioned technical proposal, numerical control combined adjuster controls main feed mechanism and stator shell is delivered to molding
Mechanism, when mechanism to be formed clamps processing to stator shell, numerical control combined adjuster controls the releasing pair of hydraulic clamp feed clamp
The clamping of stator shell makes stator shell one end at free state；When shaping mechanism completion of processing, numerical control combined adjuster
Limitation of the shaping mechanism releasing to stator shell is controlled, meanwhile, hydraulic clamp feed clamp clamps stator shell, goes forward side by side
Row feeding.In this way, when stator blank length of tube is longer, its molding stator shell stress in the process that is squeezed can be prevented
Bending, ensures the straightness of the stator tube of machine-shaping；Auxiliary feed mechanism can be in main feed mechanism by the tail of stator shell
It when end is delivered to close to shaping mechanism, takes over main feed mechanism and continues feeding, it is next stator hair to enable main feed mechanism
