Abstract

The invention relates to a round head bending device, which can bend a metal bar into a u-shaped (semicircular) and a round head (sheep eye ring) only by automatic bending and numerical control bending of large-scale enterprises in the bending equipment at present. One end of each of the upper bending arm and the lower bending arm is provided with a through hole with the same size, the two through holes are overlapped and then inserted into a main shaft, and the lower end of the main shaft is locked by a stop nail, so that the two bending arms form a hinged shape and can freely rotate; the two bending arms are provided with transverse shafts, metal bars are placed in gaps between the heads of the two transverse shafts and the main shaft, the upper bending arms are rotated, the metal bars are driven to rotate around the main shaft for nearly one circle, and the metal bars can be bent into a round head shape.

Description

Round head bending machine

Technical Field

The utility model relates to a metal bar equipment of bending, the accurate button head bending machine of saying so.

Background

In the metal bar bending equipment in the current market, only large enterprises can bend metal bars into U-shaped (semicircular) and round-head (sheep eye ring) shapes by automatic bending and numerical control bending, and the equipment is expensive, needs a lot of facilities such as fields and is not suitable for small and medium-sized processing enterprises and individual processing industries. My round head bender solves this practical problem.

Disclosure of Invention

The technical scheme of the round head bending device is as follows:

a round head bending device is characterized in that one ends of an upper bending arm (2) and a lower bending arm (1) are provided with through holes with the same size, the two through holes are overlapped and then inserted into a main shaft (5), and the lower end of the main shaft (5) is locked in the through hole of the lower bending arm (1) by a stop screw (8), so that the two bending arms form a hinged shape and can freely rotate; the upper surfaces of the upper bending arm (2) and the lower bending arm (1) are provided with transverse shaft seat frames (3), transverse shafts (4) are arranged in the 2 transverse shaft seat frames (3), and the 2 transverse shafts (4) are provided with positioning tightening caps (6).

The transverse shaft seat frame (3) is provided with inner threads, the transverse shaft (4) is provided with outer threads and is of a fine thread structure, fine adjustment of the distance of the main shaft (5) is achieved, and positioning and locking are carried out by the tightening cap (6) after the distance is adjusted.

The head of the transverse shaft (4) is cut into a symmetrical 30-degree flat tip, so that the bending machine is very suitable for bending small-diameter round heads.

The thickness of the main shaft (5) has various specifications and is selected according to requirements; the size of the inner diameter of the folded round head is determined by the thickness of the main shaft (5).

When the bending machine is used, the upper bending arm (2) is turned to the bottom anticlockwise, the flat heads of the 2 transverse shafts (4) are basically attached and closed, a gap is reserved between the upper bending arm and the main shaft (5), a metal rod (9) is placed in the gap, the upper bending arm (2) rotates clockwise, and under the combined action of the 2 transverse shafts (4) and the main shaft (5), the round head bending is achieved.

Drawings

FIG. 1 is a front view; FIG. 2 is a top view; FIG. 3 and FIG. 4 are schematic diagrams of embodiments;

FIG. 5, FIG. 6, FIG. 7 and FIG. 8 are diagrams of the effects of the embodiment;

in the figure: 1. a lower bending arm; 2. an upper bending arm; 3. a cross shaft mount; 4. a horizontal axis; 5. a main shaft; 6. tightening the cap; 7. fixing screw holes; 8. stopping the screw; 9. a metal rod;

Detailed Description

As can be seen from FIGS. 1 and 2, the transverse axis seat frame (3) and the transverse axis (4) have a thread structure, and the distance between the transverse axis seat frame and the main axis (5) can be freely adjusted according to the thickness of the metal rod (9), namely, the bending of the metal rod (9) with various specifications can be suitable.

As can also be seen from fig. 1 and 2, the head of the transverse shaft (4) is cut into a symmetrical 30-degree flat tip, which is a practice summarized by a plurality of practices, so that the design is very suitable for bending and manufacturing small-diameter round heads; because the head is cut into symmetrical angles and the transverse shaft (4) is screwed in or screwed out by rotating for half a turn (180 degrees), the angle of the corresponding main shaft (5) can be kept unchanged no matter the transverse shaft (4) is screwed in or screwed out.

It can be seen from the embodiment of fig. 3 and 4 that the round head bending device can be fixed on the workbench through the fixing screw hole (7) by screws, so that bending operation is more convenient, the upper bending arm (2) rotates to the bottom anticlockwise, the flat heads of the 2 transverse shafts (4) are basically attached and gathered together, a gap is formed between the flat heads and the main shaft (5), the gap is adjusted according to the thickness of the metal rod (9) in advance, the metal rod (9) is placed in the gap, the upper bending arm (2) rotates clockwise, the metal rod (9) is driven to rotate around the main shaft (5) for nearly one circle (360 degrees), and the metal rod (9) can be bent into a round head shape.

The upper bending arms (2) have different rotating angles and different bending sequences, so that various effects can be achieved, and U-shaped (semicircular) and round heads (sheep eye circles) in different forms can be bent. As shown in fig. 5, 6, 7, 8.

The transverse shaft (4) is formed by processing a 12.9-grade high-strength thin tooth bar.

The main shaft (5) is made of high-strength and high-hardness white steel, and is wear-resistant and durable.

The use practice proves that the device has simple structure, ingenious design, novelty, practicability and high cost performance, and is particularly suitable for small and medium-sized enterprises and the individual processing industry.
