Abstract

The utility model relates to a machining device for the screw threads of reinforcing steel, which mainly comprises a cutting part and an automatic feed part, wherein the cutting part is composed of components, such as a die head 4, etc., and the automatic feed part is composed of a screw rod 11 and opening and closing nuts 12. The cutting part is used for cutting and machining reinforcing steel, and the automatic feed part is used for controlling the screw pitch to ensure the machining quality of the screw threads. The connecting screw threads of the reinforcing steel can be conveniently and quickly machined out by using the device, and the machining quality of the screw threads can be ensured. The machining device has the advantages of convenient assembly and debugging, low gravity center, good stability, flexible and convenient operation, and low technique and experience request of the operator, and can be widely used for the sites of building construction.

Description

A kind of steel bar joint screw process equipment

The utility model relates to a kind of with the end reinforced equipment that processes connecting thread.

At building field, the connection of reinforcing bar is the problem that people extremely are concerned about, being threaded is one of main method of attachment of reinforcing bar.Present steel bar joint screw process equipment requires the operator that certain technology and experience are arranged, the steel bar joint screw difficult quality guarantee that processes, but also can not process long connecting thread.

The purpose of this utility model is: a kind of steel bar joint screw process equipment is provided.This equipment assembling and setting is convenient; Center of gravity is hanged down good stability; Flexible and convenient operation, less demanding to operator's technology and experience, the connecting thread quality that processes guarantees easily; Can process long connecting thread.

The technical solution of the utility model is: reinforcing bar is gripped by jaw, and the rotation of motor is arrived main shaft through decelerator and gear transmission.Rotate by the die-head that is fixed on spindle end and to process end reinforced connecting thread.Structurally by two lead rail axis that are fixed on the main spindle box jaw, sheath are linked together, to guarantee the axiality between jaw, sheath and the die-head, make assembling and setting convenient, component movement is flexible.By motor and decelerator being installed in below the main spindle box, improve stability to lower the center of gravity.By installing the self-acting feed mechanism that forms by screw mandrel and clasp nut additional, to guarantee the crudy of steel bar joint screw.By processing the hole of diameter, make this equipment can process long connecting thread greater than processing steel bar joint screw external diameter at main shaft left end center.

The utility model is compared with background technology, and the beneficial effect that has is: this equipment assembles, debugging is convenient, flexible operation; Center of gravity is low, good stability when transportation and work; Technology and experience to the operator are less demanding, and the steel bar joint screw quality of being processed guarantees easily; Can process long connecting thread.

Below in conjunction with accompanying drawing the utility model is described in detail:

Accompanying drawing, operation principle of the present utility model and structure diagram

As shown in drawings: the right is mounted with main spindle box 7 on frame 1, and two lead rail axis 20 parallel with main shaft 8 are housed on the main spindle box 7, and the jaw 3 of clamping reinforcing bar 2 is located by two lead rail axis 20, is fastened on lead rail axis 20 left ends and the frame 1.Sheath 5 is installed on two lead rail axis 20, can be as required along lead rail axis 20 move left and right.Decelerator 17 is fixed on main spindle box 7 bottoms, and motor 14 is fixed on the decelerator 17, and the gear 18 of the rotation of motor 14 through being fixed on decelerator 17 output shafts is delivered to third wheel 19, and then is delivered to gear 6.Gear 6 is installed on the main spindle box 7, and the rotation of gear 6 transmits motion to by spline on the main shaft 8 that is positioned at its center, and main shaft 8 transmits motion to the die-head 4 that is fixed together with its left end.Die-head 4 is installed in the macropore of sheath 5.

Cover 10 is fixed in the hole on main spindle box 7 the right, and its top is fixed with a stop pin 9.Cover 13 and the cylindrical on main shaft 8 the right movingly, with the endoporus of cover 10 movingly.Stop pin 9 places cover 13 is not rotated with main shaft 8.Gear 16 has a groove below the cover 10 so that can mesh with the stripe shape tooth below the cover 13.Gear 16 is fixed on the Handle axis 15.The screw mandrel 11 that is fixed on main shaft 8 right-hand members can mesh or open when needed with the clasp nut 12 that is installed in main spindle box 7 right-hand members.During engagement: die-head 4 can produce a feed motion left when rotating under main shaft 8 drives, so that the steel bar joint screw pitch that processes is accurate, thus the crudy of assurance connecting thread.When opening: by the handle (not shown) that is installed on the Handle axis 15 gear 16 is rotated, and then can make cover 13 drive main shaft 8 motion to the left or to the right fast with gear 16 engagements.

Because the connecting thread length that will process is sometimes also held the effective length that processes connecting thread greater than die-head 4 inside greater than the impulse stroke of this connecting thread process equipment.This equipment just can process the connecting thread of Len req by get sufficiently long hole greater than the connecting thread external diameter at main shaft 8 left end centers to hold the longer connecting thread that processes, to re-use the method that connects cutter.
