Abstract
The utility model relates to a novel elbow device, which belongs to an elbow mechanical technology field. The elbow device comprises a base, a back-up block, a lever, a guide plate, a reset spring, a ratcheting and a pawl, the key is that a plurality of pipe chases which corresponds to pipe diameters are opened on the ratcheting, on which pipe button frames with pipe buttons which corresponds to the pipe chases are further arranged. The utility model has the advantages of reliable and simple structure, easy production and manufacturing, low cost, and convenient using and operation, thereby reducing the labor intensity, improving the elbow quality, and having an excellent popularizing application prospect.
Description
Technical field
The utility model relates to pipe bending machine, and particularly the apparatus for bending of thin-walled tube belongs to the bending field of mechanical technique.
Background technology
Existing swan neck system is made of pedestal, back-up block, lever, guide plate, back-moving spring, ratchet, ratchet etc., when bending tube, particularly during the bending light-wall pipe, usually can cause the curved flat of thin-walled tube.Thereby, carry out bending after in pipe, filling fine sand and tamping usually in order to prevent the curved flat of pipe.However, thin-walled tube is still often bent flat even is broken, and causes waste product.
Summary of the invention
The purpose of this utility model is exactly the deficiency that exists at existing swan neck system, provides a kind of pipe of avoiding when bend pipe to bend novel swan neck system flat and that break.
The purpose of this utility model is to realize by the improvement to existing swan neck system, novel swan neck system, comprise pedestal, back-up block, lever, guide plate, back-moving spring, ratchet, ratchet, it is characterized in that having on the ratchet some kinds and the corresponding tube seat of caliber, the pipe thread frame that has pipe thread with tube seat accordingly also is installed on the ratchet.On the said pipe thread frame a plurality of pipe threads are arranged, the pipe thread frame is connected on the ratchet with bolt.To need pipe one end of bending to be placed on the back-up block, the other end places in the pipe thread of the pipe thread frame that is fixed on the ratchet.During bending, pull lever back and forth, by the motion of lever drives ratchet, the ratchet driving pawl rotates.Along with the rotation of ratchet, pipe on the ratchet tube seat and by bending gradually, curved during to the angle that needs, unclamp lever, just can directly in tube seat, be taken out by the pipe of bending.Pull lever, ratchet and ratchet are thrown off, but ratchet homing then, for task is ready down.The effect of back-moving spring can be got back to original position after being to make ratchet action once, so that drive next ratchet.One protruding column is arranged on the ratchet, and under action of reset spring, this cylinder is close to guide plate, and moves along the curved surfaces of guide plate, and the guiding and the effect that prevents to beat are played in the motion of ratchet.In addition, this device can be selected corresponding pipe thread to the bending of different pipes, can also select suitable pipe thread for use by changing the pipe thread frame, thereby make it obtain corresponding bending fillet and tube seat, in the bending process, be close to tube seat by the tube outer wall of bending, the tube seat arc surface forms uniform pressure to pipe, has avoided pipe by curved flat; And corresponding bending fillet has avoided causing because of the bending fillet is too small the situation of breaking again.
The utility model is rational in infrastructure simple, manufactures easily, and cost is low.Use easy to operately, reduce labour intensity, improve bending quality, good popularization and application prospect is arranged.

Accompanying drawing 1 is a main TV structure schematic diagram of the present utility model.
Accompanying drawing 2 is a left TV structure schematic diagram of the present utility model.
Accompanying drawing 3 is a ratchet structure schematic diagram of the present utility model.
Accompanying drawing 4 is the sectional structure schematic diagram of ratchet of the present utility model.
1 pipe thread frame, 2 ratchets, 3 ratchets, 4 guide plates, 5 back-up blocks, 6 pedestals, 7 levers, 8 back-moving springs, 9 ratchets, 10 tube seats, 11 pipe threads among the figure.
The specific embodiment
Pipe thread frame 1 is installed on the ratchet 2 by bolt; Ratchet 3 is provided with cylinder, is connected with lever 7 by bolt.Back-moving spring 8 one ends are fixed on the lever 7, and the other end is fixed on the ratchet 3.Guide plate 4 links to each other with pedestal 6 by bolt.During work, will need pipe one end of bending to be placed on the back-up block, the other end places in the pipe thread of the pipe thread frame that is fixed on the ratchet.Pull lever 7, back-moving spring 8 drives ratchets 3 motions, and ratchet 3 is moved along guide plate 4 by cylinder control on the ratchet, drives ratchet 2 simultaneously and rotates, and is close on the ratchet 2 pipe in the tube seat by bending thereby make.
Claims (2)
1, a kind of novel swan neck system, comprise pedestal, back-up block, lever, guide plate, back-moving spring, ratchet, ratchet, it is characterized in that having on the ratchet (2) some kinds and the corresponding tube seat of caliber (10), the pipe thread frame (1) that has pipe thread (11) with tube seat (10) accordingly also is installed on the ratchet (2).
