Description
Technical Field
The invention relates to the field of laser cutting, in particular to a waste breaking method suitable for a laser cutting trepanning.
Background
The current method of disposing of the scrap is to generate a scrap split line in a grid form around the part according to the set interval of the scrap lines at the time of nesting, and then insert the front or rear of the G-code. However, this solution is too ideal, and the actual production situation is often complex. Because the scrap lines are generated in advance, the general scrap generation rule is that the scrap lines are cut together, and the parts are easily cut once the plates are deformed or misplaced, whether before or after the parts. This is particularly true for sheet materials having a thickness in excess of 10 mm. The cutting of thick plates requires a more powerful laser, the heat generated can cause the local area to generate obvious thermal deformation, and the deformation of the surrounding area after cutting can cause the waste wires cut in advance or finally to be staggered, so that the part is cut. In addition, the four-side frames cannot be processed by the original waste line scheme, and the problem of difficult sorting still exists. And because the bending state of the steel plate and the stress release generated by the separation of the parts and the plates in the cutting process are very easy to occur that the small waste sticks up and strikes the cutting head, the nozzle is light, the protective mirror is scrapped, and the cutting head is damaged if heavy. This can lead to cut-off, affecting production efficiency.
There is also a visual scheme. Based on the photos taken by the vision system, the cutting track is temporarily increased by a software algorithm to realize scrap segmentation. This solution is firstly expensive in the vision system and the medium-low end cutting machine cannot be equipped. And secondly, only the breaking between two parts needs repeated photographing calculation by a visual system, a track is generated after verification and is inserted into a cutting program, the time consumption of one set of process is not less than 2 minutes, the production process is prolonged, and the production efficiency is reduced.

Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
In order to solve the problems in the prior art, the embodiment of the invention provides a waste breaking method and a waste breaking system suitable for laser cutting of a sleeve material.
Example 1
The embodiment discloses a waste breaking method suitable for laser cutting of a trepanning, as shown in fig. 1 and 2, comprising:
S100, determining the type of enabling a waste line according to the sizes of the parts forming the plate; wherein, in particular, the waste line, which we call a waste cut line, one sheet of steel removes part, and the remainder is the waste, and the waste line is a cutting line cutting this waste region. The scrap wire is an independent wire segment, the length is generally smaller than 300mm according to a set value, the cutting of the scrap wire does not lead to the thermal deformation of the plate, then the part is cut, the thermal effect or stress state of the plate is approximately similar to that of the scrap wire cutting, and the actual cutting coordinates of the part are within an allowable range.
In S100 of the present embodiment, determining the type of the start-up waste line according to the size of the constituent plate material parts specifically includes: when the size of the plate part is larger than a preset threshold value, the type of starting the waste material line is a fixed-length waste material line; the fixed-length waste material line is a waste material line which penetrates through the whole plate at fixed intervals on the plate.
For example, the sheet in picture 3, it can be seen that the sheet is made up of a reasonable distribution of large and medium parts. The fixed length scrap line is more suitable for larger sized parts because the number of large part ends is smaller and it is not guaranteed that a sufficient number of scrap lines can be distributed over the full size. It is very suitable to add a length of scrap line to make up the quantity at this time.
In S100 of some preferred embodiments, determining the type of the start-up waste line according to the size of the component sheet material parts, specifically further includes: when the size of the plate part is not larger than a preset threshold value, enabling the type of the waste material line to be an endpoint waste material line; the end point waste material line is a waste material line which is formed by diverging from the end point of the part to the surrounding. For example, the sheet of fig. 4, it can be seen that the sheet is formed of closely packed small and medium pieces with embedded and gap filling, so that the sheet can be used with very good results using end point waste lines.
S200, respectively carrying out parameter setting according to different preset rules according to the type of the started waste material line to generate a target waste material line;
Specifically, as shown in S100, when the type of the waste material line is a fixed-length waste material line, parameter setting is performed according to a preset rule, which specifically includes: setting a fixed interval of a horizontal and vertical waste material line, setting a distance between the waste material line and a part, and setting an overdriving length of a plate; wherein, the fixed interval of the horizontal and vertical direction waste material lines is one tenth of the size of the plate; setting a gap between the waste line and the part to represent a gap between the waste line and the edge of the part; the plate over-cut length represents the length of a theoretical plate cut out by a scrap line knife path at the edge of the plate.
When the type of the waste material line is an endpoint waste material line, parameter setting is performed according to a preset rule, and the method specifically comprises the following steps: setting the distance between the waste material line and the part and the over-cutting length of the plate; wherein, the fixed interval of the horizontal and vertical direction waste material lines is one tenth of the size of the plate; setting a gap between the waste line and the part to represent a gap between the waste line and the edge of the part; the plate over-cut length represents the length of a theoretical plate cut out by a scrap line knife path at the edge of the plate.
The present embodiment sets 500, for example, in the horizontal and vertical directions after the specified waste line generation interval. The algorithm automatically generates a horizontal or vertical scrap line based on this distance, which bypasses the parts of the pathway while maintaining a set spacing from the parts. This spacing is used to compensate for knife supplements to prevent cutting damage to the parts. Meanwhile, the method is different from the traditional algorithm, the method allows a customer to add an over-cut length, namely, a scrap line knife path on the edge of a plate can cut out a theoretical plate, because the size of the plate generated by the actual customer is always larger than that of the plate set in software, in addition, when the scrap line exceeding the plate is cut, the method is used for preventing the cutting head from sensing that the plate cannot fall out of the plate, and the exceeding part realizes the fixed-height cutting of the cutting head by enabling a following closing function.
In the embodiment, the distance between the waste material line and the part represents the distance that the waste material line cannot be attached to the edge of the part and the slit width is left, so that the laser is ensured to be in a position of just cutting off without damaging the part when the waste material line is cut off; preferably set to knife complement +0.6. In this embodiment, the over-cut length of the plate needs to be set, and because the size of the plate tends to be larger, if the frame waste wire cut is performed according to the set plate value, the plate cannot be completely cut, so that the over-cut wire needs to be added to ensure that the plate is completely cut. The parameters may be set as desired, preferably 5-10mm.
S300, deleting the generated target waste line, eliminating the waste line which does not meet the requirement, and obtaining the final waste line. Specifically, in S300 of this embodiment, the method for screening the generated target waste line includes at least: the line density of the waste material is filtered and the waste material is filtered beyond the upper limit of the length of the waste material line.
S400, inserting all waste material lines around the parts into the part cutting sequence according to the clockwise position relation on the basis of the preset part cutting sequence according to the position relation between the plate parts and the final waste material lines in S300, wherein each waste material line is only inserted once, and realizing the alternate cutting of the waste material lines and the plate parts.
In S400 of this embodiment, all scrap lines around the part are inserted in a clockwise positional relationship before the part cutting sequence. Each scrap line can be inserted only once. Thereby realizing the alternate cutting of the waste material line and the plate parts. The clockwise cutting mode is to reduce the space-time moving distance of the cutting head when frequently cutting waste materials as far as possible. In order to ensure that the cutting perforation of the waste material line does not affect the parts, a T-shaped cutting mode is adopted, wherein the adopted T-shaped cutting mode is perforation at the position of 5mm in the direction of the perpendicular bisector of the waste material line, cutting to the midpoint of the waste material line, turning back to the original starting point of the waste material line, cutting to the end point of the waste material line, and no knife repair is added. The T-shaped scrap wire cutting mode ensures that the cutting track is not contacted with the part, thereby reducing the possibility of cutting the part. The waste material lines around the preferential cutting parts avoid thermal deformation to a great extent, and the unique T-shaped waste material cutting mode of the invention further avoids cutting the parts.
The embodiment discloses a waste breaking method suitable for laser cutting of a trepanning, comprising the following steps: s100, determining the type of enabling a waste line according to the sizes of the parts forming the plate; s200, respectively carrying out parameter setting according to different preset rules according to the type of the started waste material line to generate a target waste material line; s300, deleting the generated target waste line, eliminating the waste line which does not meet the requirement, and obtaining the final waste line. S400, inserting all waste material lines around the parts into the part cutting sequence according to the clockwise position relation on the basis of the preset part cutting sequence according to the position relation between the plate parts and the final waste material lines in S300, wherein each waste material line is only inserted once, and realizing the alternate cutting of the waste material lines and the plate parts. The invention realizes the mutual separation of the parts and the waste, reasonably cuts up the waste frame, and simultaneously avoids the damage of the parts; the method can ensure that the parts are not cut, the parts are separated from the plates, the plates can be cut up integrally, and the follow-up sorting is not affected. The automatic sorting machine is suitable for the full-automatic production line, and can greatly improve the follow-up automatic sorting efficiency.
