Description

[0002] Metal ingots are extruded into profiles. If defects occur during the profile processing, the profile extrusion die needs to be repaired. Among them, the material head that indicates the flow rate plays a vital role in guiding the repair of the profile extrusion die.

[0003] In actual production, when operating the extruder, on-site personnel are essentially manually required to calibrate the slug and confirm its shape. This is cumbersome and carries the risk of hand burns during manual marking. In particular, when using a multi-hole profile extrusion die, on the one hand, it is necessary to calibrate the number of holes to connect the slugs at the corresponding hole outlet. When there are too many holes, the slugs are mixed together, making manual calibration difficult.

[0072] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the following Figure 1-10 The specific embodiments of the present invention are described in detail.

[0073] For the convenience of description, refer to Figure 1 As shown, the front-to-back direction, the up-down direction, and the left-to-right direction perpendicular to the front-to-back direction and the up-down direction are defined, wherein the output direction of the profile is defined as the front.

[0074] See attached Figure 1 and 2 A first aspect of the present invention provides a profile head flow rate recording device 100, which is applied to an extruder. The extruder is used to extrude metal ingots into profiles, including a front beam base 110. The front beam base 110 is a hollow structure for outputting profiles. The front beam base 110 includes a first hole 111. A laser marking machine 120 is provided on the inner wall of the first hole 111. The laser marking machine 120 includes a laser marking head 121. The laser marking head 121 is used to mark information on the surface of the profile.

[0075] It should be noted that when an extruder stops working abnormally, it can be roughly divided into three situations: extrusion flow rate problems, unqualified profile dimensions, or profile surface defects. Among them, unqualified profile dimensions and profile surface defects are related to the extrusion flow rate. When the extrusion flow rate problem is serious, the profile may block the holes of the profile extrusion die, the profile may bend and deform, or the discharge lengths of the various holes of the profile extrusion die 300 may vary greatly, making subsequent traction operations impossible. The profile head can indicate the speed of the extrusion flow rate and can be used to guide the subsequent repair of the profile extrusion die 300.

[0076] For a single-hole profile extrusion die 300, the information marking includes the die model, die serial number, extruder serial number, metal ingot information, date, and team information. When single-hole profile extrusion dies 300 are batched onto the machine, the marked profiles are easily distinguished when they are piled together, and the marked information facilitates tracking of problematic profile extrusion dies 300.

When a batch of single-extrusion multi-hole profile extrusion dies 300 is loaded onto the machine, the marked profiles are easily distinguished and easily tracked based on the marked information. In addition, the serial number and number of holes in the profile extrusion die 300 can be effectively divided and marked, facilitating subsequent analysis of the profile extrusion die 300.

When the protective cover 125 blocks the laser marking head 121 , the first sensor 124 can detect whether the profile enters the area where the laser marking machine 120 is located through the first through hole 1253 .
