Abstract

The utility model provides a manual U-shaped pipe bending device, which is characterized by comprising a bottom plate, a fork-shaped handle, an upper clamping block and a lower clamping block, wherein a concave fork of the fork-shaped handle is internally provided with a fixed wheel and a rotating wheel; a fixed pin shaft penetrates through the fork-shaped handle and the fixed wheel to be fixed on the bottom plate; the fork-shaped handle can drive the rotting wheel to rotate by taking the fixed pin shaft as an axle; annular grooves are arranged at the excircle parts of the fixed wheel and the rotating wheel and are corresponding to each other; and the upper clamping block and the lower clamping block are also provided with grooves matched with the annular grooves on the fixed wheel and the rotating wheel for use and are vertical to each other in direction. The manual U-shaped pipe bending device well solves the problems that in the pipe bending process, a bent part often collapses inwards, and the appearance size of the bent part is not accurate.

Description

Technical field

The utility model relates to a kind of manual bend pipe frock, the manual pipe bender of particularly a kind of U type pipe.

Background technology

In the manufacturing process of the small-sized pipe fitting bend pipe of curtain wall industry, because workpiece is thin and external diameter is less, frequent turn of bilge inwardly subsides in the bend pipe process, and appearance and size is inaccurate, causes workpiece to scrap, and working (machining) efficiency is low, and quality is unstable.

Summary of the invention

The utility model purpose: the utility model provides a kind of U type pipe manual pipe bender, its objective is the problem that the turn of bilge that often occurs in the solution bend pipe process in the past inwardly subsides and appearance and size is inaccurate.

Technical scheme: the utility model is realized through following technical scheme:

The manual pipe bender of a kind of U type pipe is characterized in that: this pipe bender comprises base plate, forked type handle, upper clamping block and following clamp; Be provided with fast pulley and moving runner in the recessed fork of forked type handle; Fixed pin shaft passes the forked type handle and fast pulley is fixed on the base plate; It is the axle rotation with the fixed pin shaft that the forked type handle can drive moving runner; The cylindrical portion of fast pulley and moving runner is provided with annular groove, and fast pulley is corresponding with the annular groove on the moving runner; Also be provided with on upper clamping block and the following clamp with fast pulley and moving runner on the groove that is used of annular groove, upper clamping block is vertical each other with the groove direction on the following clamp.

Upper clamping block is arranged on the clamping seats through the adjustment screw, and following clamp is arranged on down on the clamping seats through the adjustment screw.

Groove on the following clamp is corresponding with last clamping seats.

Advantage and effect: the utility model provides a kind of U type pipe manual pipe bender, and this pipe bender comprises base plate, forked type handle, upper clamping block and following clamp; Be provided with fast pulley and moving runner in the recessed fork of forked type handle; Fixed pin shaft passes the forked type handle and fast pulley is fixed on the base plate; It is the axle rotation with the fixed pin shaft that the forked type handle can drive moving runner; The cylindrical portion of fast pulley and moving runner is provided with annular groove, and fast pulley is corresponding with the annular groove on the moving runner; Also be provided with on upper clamping block and the following clamp with fast pulley and moving runner on the groove that is used of annular groove, upper clamping block is vertical each other with the groove direction on the following clamp.

Advantage and the good effect that the utlity model has are:

Owing to adopt technique scheme, the utlity model has following beneficial effect:

It has solved, and frequent turn of bilge inwardly subsides in the bend pipe process, and appearance and size is inaccurate, and it is simple in structure, and loading and unloading are easy, easy to adjust flexibly, speed is fast, and handling safety reliably, significantly improves operating efficiency, steady quality.

Sequence number explanation among the figure:

1 forked type handle, 2 rotating pins, 3 fixed pin shafts, 4 moving runners, 5 fast pulleys, 6 upper clamping blocks, clamping seats on 7,8 adjustment screws, 9 base plates, 10 times clamping seats, 11 times clamps.

The specific embodiment:Below in conjunction with accompanying drawing the utility model is done further explanation:

As shown in Figure 1, the utility model relates to the manual pipe bender of a kind of U type pipe, and this pipe bender comprises base plate 9, forked type handle 1, upper clamping block 6 and following clamp 11; Be provided with fast pulley 5 and moving runner 4 in the recessed fork of forked type handle 1; Fixed pin shaft 3 passes forked type handle 1 and fast pulley 5 is fixed on the base plate 9; It serves as the axle rotation with fixed pin shaft 3 that forked type handle 1 can drive moving runner 4; The cylindrical portion of fast pulley 5 and moving runner 4 is provided with annular groove, and fast pulley 5 is corresponding with the annular groove on the moving runner 4; Also be provided with on upper clamping block 6 and the following clamp 11 with fast pulley 5 and moving runner 4 on the groove that is used of annular groove, the direction of the groove 12 on upper clamping block 6 and the following clamp 11 is vertical each other.Moving runner 4 is arranged on the forked type handle 1 through rotating pin 2.

Upper clamping block 6 is arranged on the clamping seats 7 through the adjustment screw; That is to say that upper clamping block 6 is screwed in an end of an adjustment screw 8; This adjustment screw 8 passes clamping seats 7; Threaded engagement between this adjustment screw 8 and the last clamping seats 7 through screwing adjustment screw 8, is adjusted the position of upper clamping block 6; Following clamp 11 is arranged on down on the clamping seats 10 through another root adjustment screw; In like manner; Following clamp 11 is screwed in an end of this adjustment screw, and this adjustment screw passes down clamping seats 10, threaded engagement between this adjustment screw and the following clamping seats 10; Through screwing the adjustment screw, adjust down the position of clamp 11.

Groove on the following clamp 11 is corresponding with last clamping seats 7, that is to say that the groove on the following clamp 11 cooperates with last clamping seats 7 clamps the pipe that is bent.

Earlier forked type handle 1 is revolved by the direction of C arrow among Fig. 1 during the utility model work and turn 90 degrees as original position; Then pipe to be processed is penetrated in the annular groove between fast pulley 5 and the moving runner 4, the other end is pressed the direction rotation forked type handle 1 of the D arrow among Fig. 1 and is accomplished first curved processing with clamp 11 clampings down; Take out pipe to be processed then; With forked type handle 1 cycle original position, with the curved good end of pipe to be processed, clamp again again with upper clamping block 6; The pipe other end to be processed is penetrated in the annular groove between fast pulley 5 and the moving runner 4, be rotated counterclockwise forked type handle 1 by the D direction of arrow direction among Fig. 1 and accomplish second curved processing.

This utility model has well solved the problem that often turn of bilge inwardly subsides and appearance and size is inaccurate in the bend pipe process.
