Description

Automatic pipe cutting machine for heating pipe

technical field

The utility model relates to a pipe cutting device, in particular to an automatic pipe cutting machine for heating pipes.

Background technique

In the processing of heating tubes, cutting of tubes is a basic step, mainly to cut long tubes into short tubes of required length for use. The existing processing methods generally have the following types:

1. Manually measure the length, mark equidistant distances on the steel pipe, and then use cutting tools to cut manually. The full name of this method is manual, and the processing accuracy and efficiency cannot be guaranteed;

2. Adopt automatic pipe cutting equipment. In order to automate the processing of pipe cutting, automatic pipe cutting equipment has appeared on the market. This type of equipment transports long pipes through the conveying mechanism and calculates the conveying length. After conveying to the predetermined length, through The cutter mechanism cuts, but due to the inertia of the existing conveying mechanism during operation, during the time interval between conveying to a predetermined length and stopping, the pipe actually still moves forward for a certain distance, which is difficult to calculate and control , so although the existing processing equipment can greatly improve the processing efficiency, there are still problems in accuracy.

Utility model content

In order to solve the above technical problems, the utility model provides an automatic pipe cutting machine for heating pipes that can not only ensure the cutting efficiency of the pipes, but also effectively improve the processing accuracy.

In order to achieve the above object, the utility model adopts the following technical solutions:

The pipe cutting machine includes a machine platform, a conveying mechanism that can clamp and loosen the pipe material and control the horizontal running of the pipe material is provided at the first end of the machine table, and a stopper for preventing the pipe material from running is provided at the second end of the machine table block, and a pipe cutting mechanism is arranged between the conveying mechanism and the block.

Preferably, the conveying mechanism includes a horizontal hollow roller, the two ends of the hollow roller are installed on the machine table through bearings, the hollow roller is equipped with a cylinder for clamping the pipe inside the hollow roller, and the hollow roller is connected with a clamping A motor that turns the tube to make the cut.

Preferably, a pipe material rack is provided on one side of the first end of the machine table, and the pipe material rack includes a discharge slope, and the lowest end of the discharge slope on the end of the pipe material rack far away from the machine table is There is a propelling device for propelling the lowermost pipe to the conveying mechanism.

Preferably, the conveying mechanism includes two sets of conveying wheels installed vertically, the one set of conveying wheels is connected with a driving motor, and the other set of conveying wheels is connected with a cylinder that drives the two sets of conveying wheels to approach and move away.

Due to the adoption of the above structure, the automatic pipe cutting machine for heating pipes of the present invention adjusts the distance between the stopper and the pipe cutting mechanism to a distance equal to the required pipe length before processing. After reaching the predetermined length, the pipe resists the stopper, avoiding the error caused by the inertia of the conveying mechanism on the length of the pipe, and improving the processing accuracy of the pipe while ensuring the processing efficiency.

Description of drawings

Fig. 1 is a schematic structural view of an embodiment of the utility model.

detailed description

As shown in Figure 1, the automatic pipe cutting machine for heating pipes and pipes according to the embodiment of the present invention includes a machine 1, and a conveyor that can clamp and loosen the pipes and control the horizontal operation of the pipes is provided at the first end of the machine 1. Mechanism 2, the second end of the machine 1 is provided with a stopper 3 that prevents the pipe from running, and a pipe cutting mechanism 4 is provided between the conveying mechanism 2 and the stopper 3 .

Before processing, first adjust the distance between the block 3 and the pipe cutting mechanism 4 to be equal to the required pipe cutting length. When working, the conveying mechanism drives the pipe raw materials to run in the direction of the pipe cutting mechanism 4 and the block 3. When the pipe material advances to the block 3, the running track of the pipe material is blocked and stops running. At this time, the pipe cutting mechanism 4 cuts the pipe material, and the resulting pipe material is a pipe material of predetermined length.

Since the traditional down-pressing cutter or saw needs to completely pass through the cross-section of the pipe when cutting the pipe, during this process, a large pressure is applied to the pipe, which often causes bending deformation in the cut. In order to solve this problem, this paper In the embodiment, the conveying mechanism 1 includes a horizontal hollow drum 21, the two ends of the hollow drum 21 are installed on the machine platform 1 through bearings 22, and the hollow drum 21 is equipped with a cylinder for clamping the pipe in the hollow drum 21 23. The hollow drum 21 is connected with a motor 24 for clamping and rotating the pipe material for cutting.

In order to further realize the automation of feeding, in this embodiment, the first end side of the machine 1 is provided with a tube material rack 5, and the tube material rack 5 includes a discharge slope 51, the On the pipe material rack 51, a propulsion device 52 is provided at the lowest point of the discharge slope 51 away from the end of the machine platform 1 to push the bottom pipe towards the conveying mechanism.

In the conveying part of the conveying mechanism 2, in the present embodiment, the conveying mechanism 2 includes two sets of conveying wheels 25 installed vertically, the conveying wheels 25 of one set are connected with a driving motor 26, and the other set of conveying wheels 25 The conveying wheels 25 are connected with cylinders 27 that drive the two groups of conveying wheels 25 to approach and move away.
