Description

A New Planetary Pipe Rolling Mill

technical field

The invention relates to a pipe processing equipment, in particular to a planetary pipe rolling machine, which belongs to the technical field of pipe processing equipment.

Background technique

The planetary pipe rolling mill in the prior art is usually provided with a row of side-by-side conveying rollers to convey the tube blank. When the bending degree of the tube blank is large, it is easy to make the wall thickness of the processed pipe uneven, and the quality of the product is poor.

At the same time, the above-mentioned planetary pipe rolling machine often produces a large amount of chips and a mixture of coolant during the tube removal process. If the chips fly out, it will threaten the safety of the staff, and the two types of waste cannot be separated and collected well, and will lead to the deterioration of the production environment. At the same time, the high temperature generated during the extubation process is likely to oxidize the surface of the pipeline, thereby affecting the quality of the product.

Therefore, in order to solve the above technical problems, it is indeed necessary to provide a planetary pipe rolling mill with an improved structure to overcome the defects in the prior art.

Contents of the invention

In order to solve the above problems, the object of the present invention is to provide a novel planetary pipe mill with simple structure, straightening function, chip collection function and anti-oxidation function.

In order to achieve the above object, the technical solution adopted by the present invention is: a new type of planetary pipe rolling mill, which includes an upper conveying roller set, a lower conveying roller set, a straightening mechanism, a pipe drawing die, a nitrogen protection device, a chip collection box, a cooling Liquid collection box and discharge roller; wherein, a tube blank channel is set between the upper conveyor roller set and the lower conveyor roller set; the straightening mechanism is set in the tube blank channel; the tube drawing die is set on the upper conveyor One side of the roller group and the lower conveying roller group is accommodated in the chip collection box, and the nitrogen protection device is provided on the top; the coolant collection box is arranged under the chip collection box; One side of the pipe mold.

The novel planetary pipe rolling mill of the present invention is further configured as follows: a filter screen layer is provided between the swarf collection box and the coolant collection box.

The novel planetary pipe rolling mill of the present invention is further configured as follows: a discharge port is provided at the bottom of the swarf collection box.

The novel planetary pipe rolling mill of the present invention can also be configured as follows: a gas pipe is connected to the nitrogen protection device.

Compared with the prior art, the present invention has the following beneficial effects:

1. The new type of planetary pipe rolling mill of the present invention can straighten the tube billet during the conveying process by setting two rows of conveying rollers and a straightening mechanism, so as to facilitate the processing of the subsequent process;

2. The new type of planetary pipe mill of the present invention can recover the chips and the coolant separately by adding the chip collection box and the coolant collection box, so as to prevent the chips from flying out and hurt people, and at the same time, it can also keep the production environment clean;

3. The new planetary pipe rolling mill of the present invention is equipped with a nitrogen protection device, thereby avoiding the oxidation of the pipe surface during the extubation process and improving the quality of the product; at the same time, the nitrogen can also reduce the extubation temperature.

Description of drawings

Fig. 1 is a schematic diagram of the planetary pipe rolling mill of the present invention.

Detailed ways

Please refer to the accompanying drawing 1 of the specification, the present invention is a novel planetary pipe rolling mill, which consists of an upper conveying roller set 11, a lower conveying roller set 12, a straightening mechanism 2, a pipe drawing die 3, a nitrogen protection device 4, and cutting chips The collection box 5, the coolant collection box 6 and the discharge roller 7 are composed of several parts.

Wherein, a tube blank channel 13 is provided between the upper conveying roller set 11 and the lower conveying roller set 12 . After the tube blank 9 passes through the tube blank channel 13, it enters the tube drawing process, and is prevented from vibrating up and down by the pressure of the upper conveying roller set 11 and the lower conveying roller set 12 .

The straightening mechanism 2 is arranged at the front end of the tube blank passage 13, and the tube blank 9 is straightened after passing through the straightening mechanism 2, so as to facilitate extruding and forming.

The extubation die 3 is arranged on one side of the upper conveying roller set 11 and the lower conveying roller set 12, and is housed in the chip collection box 5, and the nitrogen protection device 4 is provided on the top thereof.

The nitrogen protection device 4 is connected with a gas pipe 41 through which gas is supplied to the nitrogen protection device 4 so that the extubation process is protected under a nitrogen atmosphere.

The chip collection box 5 is used to collect the chips generated by the extubation die 3, so as to prevent the chips from flying out and hurting workers. A discharge opening 51 is provided at the bottom of the chip collection box 5 , through which the chips can be cleaned in a concentrated manner.

The coolant collection box 6 is located at the bottom of the chip collection box 5 . A filter layer 8 is provided between the chip collection box 5 and the coolant collection box 6, through which the chips and the coolant can be separated and recovered separately.

The discharge roller 7 is arranged on one side of the extruding die 3, and it is used for conveying the formed pipe out.

The specific implementation above is only a preferred embodiment of this creation, and is not intended to limit this creation. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of this creation should be included in this creation. within the scope of protection.
