Description

[Technical field]

[0001] The utility model relates to the technical field of pipe bending machine processing, in particular to the technical field of a feeding mechanism of a pipe bending machine. [Background technology]

[0002] Pipe bending machines can be roughly divided into CNC pipe bending machines, hydraulic pipe bending machines, etc. They are mainly used for laying and repairing pipes in power construction, road and railway construction, boilers, bridges, ships, furniture, decoration, etc. They have the advantages of multiple functions, reasonable structure, and simple operation. In addition to the pipe bending function, the pipe bending machine can also use the oil cylinder as a hydraulic jack. In the machinery industry, pipe bending machines are used to make metal pipes with various bending angles and curve shapes, and are used to manufacture parts for various mechanical equipment. For example, machine tools, industrial robots, conveying equipment and other mechanical equipment all require a large number of metal pipes for processing and installation. The emergence of pipe bending machines can facilitate the production of these pipes while ensuring the accuracy and strength requirements and improving production efficiency. At present, in the process of using pipe bending machines to process pipes, operators are required to constantly bend over and transfer the pipes from the ground to the pipe bending machine for processing, which not only greatly consumes the operator's physical strength and increases labor intensity, but also causes discomfort to the operator's waist, and has low practicality.

[0003] In order to solve the problems raised in the background technology, the publication number CN210702177U discloses an automatic feeding pipe bending machine. When the pipe needs to be processed, the opening and closing of the discharge port can be controlled by the electric telescopic rod and the baffle, and then the discharge of the pipe can be controlled. The vibration motor is used to facilitate the discharge of the pipe. The pipe falls onto the conveying mechanism. Under the action of the conveying mechanism, the pipe is transported to the pipe bending machine body. There is no need for the operator to bend down constantly to get the pipe from the ground to the pipe bending machine body for processing. It not only saves the operator's physical strength and reduces the labor intensity, but also avoids the discomfort caused to the operator's waist by bending for a long time. However, the structure still has the following shortcomings:

[0004] 1. This structure requires the use of a vibration motor to facilitate the discharge of pipes, but the vibration method can easily cause the pipes to be bumped and damaged, and the use of a vibration motor has a large power and high cost.

[0005] 2. The structure lacks a clamping mechanism, which causes the pipes to easily fall off during transportation. The fallen pipes need to be picked up by the staff, thus affecting the work progress. [Contents of the utility model]

[0006] The purpose of the utility model is to solve the problems in the prior art and propose a feeding mechanism for a pipe bending machine, which can make the pipe automatically slide to the discharge port to avoid collision due to vibration, and prevent the pipe from falling off during transportation through a clamping structure, thereby improving stability.

[0007] To achieve the above-mentioned purpose, the utility model proposes a feeding mechanism for a pipe bending machine, including a workbench, supporting feet, a discharge box, baffles, supporting columns, a cross bracket, a feeding structure, and a clamping structure. A plurality of supporting feet are arranged below the workbench, a discharge box is arranged on one side above the workbench, baffles with L-shaped structures are symmetrically arranged on both sides of the discharge port of the discharge box, a plurality of supporting columns are vertically arranged on the other side above the workbench, a plurality of cross brackets are installed above the supporting columns, a feeding structure is arranged inside the cross brackets, a clamping structure is arranged between the cross brackets, and the clamping structure is connected and coordinated with the feeding structure.

[0008] Preferably, the discharge box is divided into an upper box body and a lower box body, the upper box body is in a V-shaped structure, the width of the feed port of the upper box body gradually decreases from top to bottom, the lower box body is inclined, and the upper box body and the lower box body are connected to each other.

[0009] Preferably, the feeding structure includes a rotating rod, a rotating motor, and a sliding block. The rotating rod is rotatably arranged inside the cross bracket, the rotating motor is arranged on the outer wall of the cross bracket, the output end of the rotating motor passes through the cross bracket and is connected to the rotating rod, and a sliding block is movably arranged on the outer wall of the rotating rod.

[0010] Preferably, the clamping structure includes a horizontal plate, an electric telescopic rod, a connecting block, and an electric clamping block. Both ends of the horizontal plate are connected to the sliding block, the electric telescopic rod is connected to the bottom of the horizontal plate, the end of the electric telescopic rod is connected to the connecting block, and the electric clamping block is symmetrically arranged below the connecting block.

[0011] Preferably, the inner side wall of the electric clamping block is in an arc structure.

[0012] Preferably, a control panel is provided on the outer side wall of the workbench, and the control panel is electrically connected to the rotating motor, the electric telescopic rod and the electric clamping block respectively.

[0013] Beneficial effects of the utility model:

[0014] 1. The utility model can make the pipes automatically slide to the discharge port through the cooperation of the discharge box and the baffle. After a number of pipes to be processed are neatly placed horizontally in the discharge box, since the upper box body of the discharge box is a V-shaped structure, the pipes will enter the lower box body one by one, and the lower box body is inclined. The pipes will automatically slide to the discharge port, and the baffles will be used to block the two ends of the pipes to prevent rolling out and avoid bumps and damages caused by vibration. The operation is simple and convenient, no motor operation is required, the cost is low, and the problem that the pipes need to use a vibration motor to discharge and are easily damaged by bumps and damages is solved.

[0015] 2. The utility model can prevent the pipe from falling off during transportation through the coordinated action of the feeding structure and the clamping structure. The rotating motor is started through the control panel, and the rotating motor drives the rotating rod to rotate. The rotating rod drives the sliding block to move, and then drives the clamping structure to move. After moving to the top of the pipe, the electric telescopic rod is started to descend through the control panel, and the electric clamping block is used to clamp and fix the pipe. Then, the electric telescopic rod is raised to transport the pipe to the pipe bending machine for processing. It can prevent the pipe from falling off during transportation, improve stability, facilitate subsequent processing, and solve the problem that the lack of a clamping mechanism easily causes the pipe to fall off.

[0016] The features and advantages of the present invention will be described in detail through embodiments in conjunction with the accompanying drawings.
