Description

Material cutting processing process

The present invention relates to the field of material processing technology, and particularly to material cutting processing processes.

With the continuous development of modern industry, cutting methods for materials are continuously derived, such as cutter cutting methods or laser cutting methods, and the laser cutting processing method for materials has the advantages of high cutting efficiency and high cutting precision, so it is widely used in the mechanical processing field. It is used.

In the conventional cutting processing method, the material is first automatically fed and then the input material is cut, resulting in a relatively high overall integration. However, in the current material input process, when pipe materials are fed from a conveyor belt, a large amount of pipe materials are simultaneously fed due to the action of gravity. It flows into the material input area, and if the quantity of pipe materials is large, a cross occurs between each pipe material and a material jam phenomenon occurs, which affects the continuous input of pipe materials and reduces material input efficiency. Cutting machines on the market mainly use a chuck to cut materials, and the chuck can clamp only one part of the material. The cutter then cuts and processes the material, but in the case of materials that are relatively long in length, the material is clamped only to the chuck. Therefore, the area that is not fixed to the chuck continues to shake during the cutting process, and if the shaking amplitude is too large, the material is misaligned, ultimately affecting the cutting precision of the material, and the error in the workpiece after cutting is too large, deteriorating the quality of the product. .

The main purpose of the present invention is to provide a material cutting processing process, and to solve technical problems in the prior art in which material jams easily occur when inputting material during the material cutting process and the shaking amplitude of the material during cutting is so large that cutting precision is easily reduced. .

In order to achieve the above object, the present invention provides a material cutting processing technology comprising the following steps:

S1: n materials are transferred to one side of the material blocking unit and blocked by the material blocking unit, and judging the size relationship between the n materials and the specified material input quantity m, when n ≤ m, the material blocking unit blocks the material. passing the material, and when n > m, the material blocking unit returns the material, where n and m are both natural numbers;

S2: The passed material moves to the detection unit, the detection unit detects whether a cross material jam occurs in the material, and the alarm sounds when a cross material jam occurs in the material. Continue to drop ingredients;

S3: When the material falls into the limit unit, the limit unit controls n materials to be uniformly arranged and sequentially dropped along the material drop groove;

S4: The material in the material drop groove is conveyed forward by the material feeding unit, and clamped by the material clamping unit when the material is conveyed forward to the station where cutting is required;

S5: After the material is clamped, the cutting unit cuts it to obtain a plurality of workpieces, and the material input unit performs material input;

S6: When the sensing assembly on the material feeding unit detects that there is no material in the material feeding unit, the limit unit controls the next material to drop into the material drop groove and the material feeding unit conveys it forward, repeating steps S3 - S5. steps;

S7: After cutting of n materials is completed, steps S1 - S6 are repeated until cutting of all materials is completed.

The material is first blocked by the material blocking unit before being dropped, and the material can continue to be sent forward only when the drop quantity of the material maintains the specified material input quantity, otherwise the excess material is sent back, so the material is sent to the first stage. Prevents material jam phenomenon that occurs due to excessive amount of material input. After that, the material continues to be fed, and when the material is fed into the detection unit, some materials with material cross jam are identified by the detection unit and an alarm is issued, and the material with material cross jam continues to be returned downward, causing the material to drop. It prevents jamming in the groove and prevents the next step of the process from proceeding, and identifies whether material cross jams occur at this step to prevent them from affecting the operation of subsequent stations. n materials without material cross jam are dropped into the limit unit, the limit unit controls the materials to drop them evenly one by one, and one material is driven by the material feeding unit and continuously conveyed forward, and the preset When conveyed to the position, the material clamping unit clamps the material, the cutting unit continuously cuts the material, and the workpiece obtained by cutting falls into the material feeding unit to implement material feeding, and after completing the cutting for one material; Next one material is continuously conveyed forward by the material feeding unit until cutting of all materials is completed. The cutting process adopting this method ensures that the material is fed uniformly, and uses multiple steps to prevent material cross jam from occurring during the material feeding process.

Perpendicular to the material feeding direction, the horizontal height of the bearing assembly is lower than the horizontal height of the push flat assembly, where the width of the material cross section (W) < the height difference between the bearing assembly and the push flat assembly (H) < the length of the material cross section (L) Lim - further includes;

The straightening unit can prevent the material from being transported or cut and processed in two different states, and after the material is put in, it is first clamped by the material feeding unit to achieve alignment, and then dropped back into the bearing assembly, the bearing assembly and the push flat. The assembly is used to implement the push flat of the material, and after the material is bearing by the bearing assembly, it is checked whether the push flat assembly maintains the state of transverse distribution, and the material distributed in the transverse direction has a relatively high height. Although it is small and may not be blocked by the material when the push flat assembly moves forward, the material distributed in the longitudinal direction has a relatively high height at this time, so it may be blocked by the material when the push flat assembly moves forward, and the material distributed in the longitudinal direction may not be blocked by the material when the push flat assembly moves forward. When moving, the longitudinally distributed material is pushed over and changes into a transverse distribution, so the combined use of bearing assemblies and push flat assemblies ensures that the material maintains a uniform transverse state, so that the material moves forward in a longitudinal distribution. Prevents inconsistencies in the workpiece obtained by being transported or processed from being processed, thereby affecting processing efficiency.

S12: When n ≤ m, the first driver is retracted, the stopper rotates along the second rotation direction until its material blocking surface is inclined downward, and the material drops downward;

S13: When n > m, the first driver continues to extend, and the stopper continues to rotate along the first rotation direction until the material bearing on the material blocking surface is returned.

When doing so, a plurality of conductive members form a current circuit with the material, and the material continues to drop;

S21. A plurality of conductive members each contact a plurality of materials where material cross jam occurs; Or, when the conductive member is not in contact with the material where the material cross jam occurs, a current circuit cannot be formed between the conductive member and the material, and the alarm sounds an alarm and the input of the material is stopped.
