Description

An all-in-one machine for bending and collaring pipe fittings

technical field

The utility model relates to an integrated machine for bending pipe collars.

Background technique

Existing pipe bends and collars are completed by two separate equipments: the pipe bender and the collar machine, and after the pipe bender makes small elbows, they need to be deburred, cleaned and dried by the cleaning machine before they can pass through the collar machine. The welding ring is placed on the U-shaped elbow, so three pieces of equipment are required to complete the whole process of the elbow collar. Not only the production cost is high, but also the production efficiency is low and the floor area is large.

In addition, during the bending process, the U-shaped metal elbow is cut with a serrated blade. Due to the thickness of the blade itself during the cutting process, at least twice the material thickness of the serrated blade must be cut at the same time as each U-shaped metal elbow is cut. It is wasteful, and the cutting process with a serrated blade will produce a lot of metal shavings, which not only brings a lot of trouble to the cleaning of the work site, but also produces a large amount of metal shavings attached to the U-shaped metal elbow, which cannot be welded to the workpiece in the next step, so it must be added In the cleaning process, the cleaning fluid will be discharged, and more importantly, the chips generated may cause harm to the operator's body.

The bending device of the bent pipe generally includes a driving mechanism, a bending die and a metal pipe fitting pallet. The metal pipe fitting is placed on the metal pipe fitting pallet and clamped by the bending die, and the driving mechanism drives the bending die to rotate to bend the metal pipe fitting. Since the metal pipe fitting support plate is fixed, the metal pipe fittings will move on the metal pipe fitting support plate during the bending process and there will be friction between the two, and the metal pipe fittings will wear or even thin the pipe wall due to friction, which will affect the quality of the bent product , but also increase the energy consumption of the device due to friction.

The ball screw 907 is rolled and supported by a vertical plate 906, and a synchronous pulley 905 is installed at one end. The synchronous pulley 904 and the synchronous pulley 905 are connected by a synchronous belt. The ball screw 907 wears a screw nut 908. The nut 908 is connected with the follower plate 909 .

The material guide tubes 910 are installed on the follower plate 909 through the installation support 911 , and each material guide tube 910 has a groove 9011 corresponding to the installation position.

A slide seat 912 is installed below the follower plate, corresponding to the slide rail 806 of the floor frame 801 , and the slide seat 912 and the slide rail 806 form a guiding mechanism.

Driven by the motor 903 and driven by the synchronous pulleys 904 and 905, the ball screw 907 is driven to rotate, and then the screw nut 908 drives the follower plate and the supporting mold 901 and the retaining tube 910 to slide through the slide rail. The seat guide mechanism moves smoothly.

When the workpiece is bent, the mandrel 804 extends through the retaining tube 910 into a designated position of the workpiece to play a supporting role. At this time, one end of the workpiece is clamped by the bending die, and one end is located in the groove 9011 of the supporting die 901. As the bending die rotates to bend the workpiece, the supporting die 901 also advances along with the retaining pipe 910, so that the The frictional resistance during bending effectively prevents the thinning of the outer wall of the pipe.

As shown in FIG. 16 , a discharge member 10 is also provided, which includes a discharge needle 1001 , a discharge needle mounting plate 1002 , a cylinder 1003 , a guide rod 1004 , and a guide rod centralizing plate 1005 .

The cylinder 1003 is installed on the vertical plate 906, its piston rod is connected with the mounting plate 1002, one end of the discharge needle is installed on the discharge needle mounting plate 1002, one end of the guide rod 1004 is installed on the vertical plate 906, and Pass through the mounting plate 1002, and the other end passes through the centralizing plate 1005, which plays the role of centralizing the guide rod.

After the workpiece is bent, the expansion and contraction of the piston rod of the cylinder 1003 drives the discharge needle installation plate 1002 and the discharge needle 1001 installed on it to move smoothly through the guide rod. Fittings are pushed out for removal. After the workpiece is unloaded, the cylinder 1003 is returned to the discharge needle 1001 to reset, the mandrel 804 is reset, the supporting die 901 is reset, and the bending die assembly 702 is reset.

In this embodiment, at most eight pipe materials can be bent at the same time, which greatly improves the pipe bending speed.

The degreasing mechanism 11 includes a blower 1101 , a degreasing transfer box 1102 , a discharge pipe 1103 and a discharge oil mist filter 1104 .

The blower 1101 communicates with the degreasing transmission box 1102 and is respectively installed on the fuselage 1 . One end of the discharge pipe 1103 communicates with the degreasing transmission box 1102 , and the other end is connected with a discharge oil mist filter 1104 .

After the U-bend is pushed out by the discharge needle 1001, it falls into the hopper 14 and enters the degreasing and drying transfer box 1102 for degreasing and drying process. The grease on the surface of the U-bend is removed and dried by the blower 1101. Dry, the oil mist generated in the degreasing and drying transfer box 1102 is discharged through the drain pipe 1103 and the oil mist filter 1104.

The degreased U-shaped elbow enters the conveying channel 16 through the hopper 15, and is transported to the upper hopper 17 by the conveying channel 16, and then falls into the bending pipe vibrating plate 18, and the welding ring is put into it by manual or automatic equipment. In the welding ring vibrating plate 19, then the elbow and the welding ring enter the collar mechanism 12 through slideways 20 and 21 respectively, and the welding ring is placed on the elbow by the collar mechanism 12 installed on the fuselage 1, such a A pipe bend that has put the welding ring has just been processed, and is exported by blanking outlet 22.
