Abstract
The invention discloses a high-consistency honeycomb structure body die drilling method, which comprises the steps of dividing a mud inlet hole to be drilled into two parts according to the depth direction of the mud inlet hole, drilling twice, and adopting a random drilling mode to replace the prior sequential drilling for drilling. Under the prior art, according to a sequential drilling mode, the drilled holes generate larger errors on the premise of abrasion of a drill bit and difference of the drill bit, and according to the design scheme of the invention, the errors between two adjacent hole channels are reduced as much as possible through a random drilling mode, and part of the errors are distributed into the second part of the hole channels along the depth direction through a secondary drilling mode, so that the errors between the hole channels are reduced.
Description
Technical Field
The invention relates to a drilling method of a honeycomb structural body die, in particular to a drilling method of a high-consistency honeycomb structural body die.
Background
In 7/1.2019, more than 14 provinces and cities in China implement the national six-emission regulations of gasoline vehicles in advance, the national six-regulation of gasoline vehicles is divided into two versions, namely national six a and national six b, most of the current automobile factories in China select to directly develop an after-treatment system meeting the national six b standard in the vehicle emission upgrading development process, and the mainstream national six b technical route adopts GPF (gasoline engine particle filter) to meet the technical requirements.
The existing honeycomb structure body die drilling method is a general sequential drilling method, but the method has the defects that because the die is generally made of die steel or stainless steel, a drill bit is certainly abraded after drilling holes in tens of thousands of channels, and the size error of a first hole and a last hole is about 5-8%, so that the channel-to-channel comparison is obvious.
Disclosure of Invention
The purpose of the invention is as follows: the invention aims to solve the problem that the difference among pore passages is easy to be overlarge by the traditional punching method.
The technical scheme is as follows: the invention provides the following technical scheme:
a method for drilling a high-consistency honeycomb structural body mold comprises the steps of dividing a mud inlet hole to be drilled into two parts according to the depth direction of the mud inlet hole, drilling twice, and drilling holes in a mode of randomly selecting a hole channel.
The division into two is only one idea, and the actual operation can be divided into three and four, but the operation needs a long time and is not generally adopted, and if a die with high precision or a die with high consistency is needed, the operation can be carried out in a mode of dividing into three or four.
Further, firstly, the hole channels are randomly selected according to the depth direction of the hole channels for primary punching, after all the hole channels are punched for the primary punching, the hole channels are randomly selected according to the depth direction of the hole channels for secondary punching, and after all the hole channels are punched for the secondary punching, all the punching operations are completed.
If two times of punching are randomly arranged, the difference among the pore passages can be caused, and after one time of punching is finished, the secondary punching is carried out, theoretically, only half of errors can be generated, because only half of the holes are punched, the abrasion of the drill bit is also only half, the other half of errors are in the second part of the pore passages and cannot be seen, and due to the fact that the errors are matched with the errors of the first part, the error range among the pore passages is further reduced.
Further, the employed drilling bits may be arranged side by side.
Multiple drill bits may be used in parallel to perforate multiple orifices at a time.
Furthermore, the material of the die required to be drilled is die steel or stainless steel.
Further, the depth of the first perforation is at least 5 cm.
The validity of the first punch is guaranteed.
Further, the depth of the first punch is the same as the depth of the second punch.
Has the advantages that: compared with the prior art, the invention has the advantages that:
under the prior art, according to a sequential drilling mode, the drilled holes generate larger errors on the premise of abrasion of a drill bit and difference of the drill bit, and according to the design scheme of the invention, the errors between two adjacent hole channels are reduced as much as possible through a random drilling mode, and part of the errors are distributed into the second part of the hole channels along the depth direction through a secondary drilling mode, so that the errors between the hole channels are reduced.

FIG. 1 is a schematic view of a mud inlet hole according to the present invention divided into two parts in the depth direction;
FIG. 2 is a schematic representation of a comparison of a product made according to the present invention and a product made according to the prior art.
Detailed Description
The present invention is further illustrated by the following examples, which are intended to be purely exemplary and are not intended to limit the scope of the invention, as various equivalent modifications of the invention will occur to those skilled in the art after reading the present invention and fall within the scope of the appended claims.
Examples
As shown in the attached drawings 1 and 2, the method for drilling the honeycomb structural body mold with high consistency comprises the steps of dividing a mud inlet hole to be drilled into two parts according to the depth direction of the mud inlet hole, drilling twice, and drilling in a way of randomly selecting a pore channel.
Firstly, performing primary punching by adopting a method of randomly selecting the pore channels according to the depth direction of the pore channels, performing secondary punching by adopting a method of randomly selecting the pore channels according to the depth direction of the pore channels after all the pore channels have completed the primary punching, and completing all the punching operations after all the pore channels have completed the secondary punching.
The division into two is only one idea, and the actual operation can be divided into three and four, but the operation needs a long time and is not generally adopted, and if a die with high precision or a die with high consistency is needed, the operation can be carried out in a mode of dividing into three or four.
If two times of punching are randomly arranged, the difference among the pore passages can be caused, and after one time of punching is finished, the secondary punching is carried out, theoretically, only half of errors can be generated, because only half of the holes are punched, the abrasion of the drill bit is also only half, the other half of errors are in the second part of the pore passages and cannot be seen, and due to the fact that the errors are matched with the errors of the first part, the error range among the pore passages is further reduced.
The adopted drilling bits can be arranged in parallel.
Multiple drill bits may be used in parallel to perforate multiple orifices at a time.
The material of the die required to be drilled is die steel or stainless steel.
The depth of the first perforation is at least 5 cm.
The validity of the first punch is guaranteed.
The depth of the first punch is the same as the depth of the second punch.
