Description

The pipe rib machine
Technical field
The technical program relates to a kind of pipe rib machine, belongs to field of machining.。
Technical background
The specialized machine tool of machining screw (comprising worm screw, hobboing cutter etc.) profile.Be mainly used in manufacturing industry such as machine, cutter, measurer, standard component and household utensils.The application of screw thread principle can be traced back to the spiral water lift of Greece Archimedes creation in B.C. 220 years.About 1500, in the screw thread processing unit (plant) sketch that Italian Leonardo da Vinci draws, existingly use the imagination that master screw and change gear are processed different pitch screws.1760, Britain F. Huai Yate brother obtained the patent of cutting wood screw with special arrangement.1778, U.S.'s J. Lumsden was made the screw-cutting machine with the worm gear transmission.1797, Britain's H. maudslay was made the thread chasing machine that utilizes master screw and the different screw threads of change gear turning.The twenties in 19th century, maudslay produces the tap and die that machining screw is used.After 20th century, various thread cutting machines are come out one after another.
Thread cutting machine can be divided into according to the method for machining screw: 1. screw-cutting machine.As thread chasing machine, screw-thread miller, screw grinder, tapping machine, die head threading machine etc., wherein thread chasing machine, screw-thread miller and screw grinder are processed whorl work piece, screw tool and the screw measuring tool of various precision with screwing tool or emery wheel, and tapping machine and die head threading machine are then processed mass-produced in batch nut and screw etc. with the screw tap and the wrench of particular design respectively; 2. rolling screw-threads lathe.Make workpiece produce plastic deformation to obtain screw thread with the shaping roll die, as thread rolling machine, screw-rolling machine etc., productivity ratio is higher, is applicable to the external screw thread of large quantities of, a large amount of production standard securing members and other thread connectors.
The pipe rib machine belongs to screw-cutting machine, and existing machine tool has many limitations at aspects such as the range of work and machining accuracies, demands urgently improving.
Summary of the invention
A kind of pipe rib machine of the utility model aims to provide a kind of reasonable in designly, easy and simple to handle, and working stability has satisfied the pipe body threading machine of all size.
The overall architecture of this rib machine is by upper spider, lower bearing bracket, and four backbones combine; Upper spider is square, in the center of upper spider roll assembly and cutter holder assembly is set; Four backbones of upper spider and lower bearing bracket are to support entire mechanism;
The described roll assembly of going up comprises the adjustment handwheel, adjusts screw rod, little of top roll, top roll rotating shaft, annular knurl top roll; Above assembly is installed on the upper spider by upper support frame;
Described cutter holder assembly can be realized descending cutter automatically, comprises the adjustment screw rod, screwer rotating shaft, screwer; Above assembly is installed on the upper spider by bracing frame;
Described roll assembly down has two, and is similar with the top roll modular construction, is installed on the lower bearing bracket by the lower support frame;
Last roll assembly and two following roll assemblies are positioned on the same vertical plane, and it is spaced apart to be 120 degree; Cutter holder assembly is positioned at the rear end certain distance of this vertical plane;
Rotating mechanism is as described below: be delivered to gearbox by buncher, pass to gear-box by belt pulley and belt again, gear-box is equipped with an idle gear and 3 passive action gears, by the universal drive shaft of adorning on 3 passive working gear axles, be connected to three roll steel pipes on the main frame in three rolls, rotation by roll travels forward, in the front of roll blade connecting rod and snub pulley are housed, when steel pipe moved to roll threading, by the solenoid control cylinder, cylinder promoted the stripped thread planker, on the filigree supporting plate tooth bar is housed, being seesawed by tooth bar drives the blade connecting rod and cogs, and it is moved up and down, and finishes the work of roll threading.When the screw thread of steel pipe finishes, there is electromagnetic wire to control pneumatic filigree supporting plate, lift blade, at this moment second steel pipe followed first pipe and entered roll and travel forward, first steel pipe pushed ahead, make the baffle plate on its level line bin, the magnetic valve on the baffle plate is controlled pneumatic filigree supporting plate once more, make its cutter down, advance the screw thread production of second pipe of silk, first pipe continues to move ahead simultaneously, bumps next baffle plate, solenoid control cylinder on the baffle plate is turned down the steel pipe on the bin and is fallen under the bin.
The advantage and the effect of a kind of pipe rib machine of the utility model are: cover system screw thread scope is big, and processing length is long, third gear rotating speed working (machining) efficiency height, and cover system screw thread is meticulous well-balanced, and machine shape is attractive in appearance, and is reasonable in design.Have ease for operation and high efficiency, general workman need only be familiar with very short process and just can skillfully operate this equipment, and operating efficiency is 4-6 a times of engine lathe, need not finishing tool and car centre bore.The range of work is wide, and the screw thread processing length is big: little of M8, and greatly to M42x4.5 (pitch) metric thread, a mantle fiber moulding, the screw thread processing length is to 235mm.The convenient reach scale of adjusting is consistent every screw flight length of processing.
