Description

Technical Field

[0001] The utility model relates to an inclination detection tool, in particular to an inclination detection tool used for forging, sawing or shearing a blank end face. Background Art

[0002] Forging blanking is a machining process with high output requirements and high labor intensity in mechanical processing. The forging workshop mainly uses band sawing and shearing methods. In the process of sawing and shearing, due to the wear and tension of the saw blade, or due to the inappropriate gap between the shear blades, the wear of the blades, the wear of the stopper block, etc., the end face of the cut blank will be tilted, and the inclination angle is uncertain; too large an inclination angle will cause forging defects. The industry process regulations stipulate that the inclination of the end face of the cut blank must be measured within a certain range, ≤X°, that is, 0~X°. In the forging process, a universal angle ruler is usually used to measure the end face inclination to measure the accurate angle value. However, the universal angle ruler is mostly used for fine detection of flat surfaces. It has a high cost, high operating requirements, and is easy to be damaged by bumps. The detection is time-consuming due to the difficulty in operation. Forging blanking is a rough machining process. The dynamic change of the billet inclination in large-scale blanking production needs to be measured at any time. In view of the limitations of the use of universal angle rulers, a new detection tool is urgently needed. Utility Model Content

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A tool for detecting the inclination of the end face of a forging sawing or shearing blank is special in that it comprises at least two clamping plates;

[0006] Each of the card plates is provided with a reference surface and a comparison surface connected to each other;

[0007] The detection angle between the reference surface and the comparison surface is 91° to 91.5°, and the detection angles on at least two card boards are different;

[0008] The reference surface is used to be in close contact with the side wall of the cut blank to serve as a detection reference; the comparison surface is used to be in close contact with the cut end surface of the cut blank to determine the inclination angle of the cut end surface.

[0011] The upper end surface of the vertical plate is connected to the bottom surface of the horizontal plate to form an L-shaped ruler;

[0013] Furthermore, the card board also includes a handle;

[0014] One end of the handle is connected to the outer side of the corner of the L-shaped ruler, and the upper side of the handle is flush with the upper side of the horizontal plate.

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] After the round bar material is sawed or sheared, the cut end surface has a certain inclination, and the size of the inclination is controlled by the inclination angle, inclination angle α = measurement angle a-90°. This inclination angle is not fixed in production, it changes dynamically, and must be effectively controlled. The prior art usually uses a universal angle ruler, which is fixed on one side and movable on the other side, which is cumbersome to use and inefficient. For this reason, a two-speed detection tool is designed in this embodiment. Compared with the conventional universal angle ruler, this detection tool can make a judgment by visual comparison, which is convenient for finding problems and making adjustments, and can be used quickly in mass production.

[0034] like Figure 1 , Figure 2 As shown, an inclination detection tool for forging sawing or shearing the end face of a blank provided by an embodiment of the utility model includes a pallet; the pallet includes a horizontal plate 11, a vertical plate 12 and a handle 13, all of which are made of 2 cm thick manganese steel sheet by wire cutting; the bottom surface of the horizontal plate 11 is a reference surface 1; the reference surface 1 is used to be in close contact with the side wall of the blank 3 to be cut, so as to serve as a detection reference; the side surface of the vertical plate 12 close to the bottom surface of the horizontal plate 11 is a comparison surface 2; the comparison surface 2 is used to be in close contact with the high point of the cut end face of the blank 3 to judge the inclination angle of the cut end face. The upper end surface of the vertical plate 12 is connected to the bottom surface of the horizontal plate 11, so that the horizontal plate 11 and the vertical plate 12 form an L-shaped ruler; the regular data of the inclination angle obtained according to actual measurement in this embodiment is 1°, and its limit data is 1.5°, therefore, the detection angles between the reference surface 1 and the comparison surface 2 of the two detection tools in this embodiment are 91° and 91.5° respectively; as shown Figure 2 As shown in (a), 91.5° corresponds to the section with an inclination angle of less than 1.5°, which is a first-level card used to measure whether the inclination angle is greater than 1.5°; Figure 2 As shown in (b), 91° corresponds to a detection angle of 1°, which is a 2-stage card plate used to detect whether the inclination angle is less than 1°. One end of the handle 13 is connected to the outer side of the corner of the L-shaped ruler. The handle 13 is provided with a through hole 14 for hanging. The diameter of the through hole 14 is 5 mm. An angle value mark 15 is provided on the horizontal plate 11, the vertical plate 12 or the handle 13; in this embodiment, it is arranged on the horizontal plate 11, and the angle between the reference surface 1 and the comparison surface 2 is printed on the angle value mark 15.

[0035] When in use, the reference edge 1 fits an axial line on the outer circle of the cut blank 3, and the comparison edge 2 fits the highest point through the center of the cut end face (the length of the comparison edge is designed to be greater than the diameter of the cut blank), and is compared with the measured angle of the cut blank. For visually smaller angles, use the 2nd level pallet to compare and measure whether the inclination angle is appropriate; if the angle is larger, use the 1st level pallet to compare and measure whether the inclination angle is out of tolerance. Ensure that the smaller the inclination angle, the better and meet the requirements.

[0036] When sawing or shearing in production:

[0037] 1. Identify the up and down direction of sawn material (perpendicular to the saw grain direction) or the up and down direction of sheared material;

[0038] 2. Since the inclination angle of the cut end face of the cut blank cannot be 0° (or this situation is very rare), the detection angle a is specified to be an obtuse angle, and the detection angle a is identified during production.

[0039] 3. Use a universal angle ruler to check and record the first and last pieces and self-inspection;

[0040] 4. If the saw blade (blade) has been used for a certain period of time or has been replaced, or if the angle of the blank has changed visually, use the detection tool provided in this embodiment to detect it, and make adjustments if it is abnormal; for visually smaller angles, use the 2nd gear card to compare and measure whether it is appropriate; if the angle is large, use the 1st gear card to compare whether it is out of tolerance, which is convenient for normal control and abnormal detection. In actual production, it is used about 4 to 10 times (two gears are used in total) for sawing 1,000 pieces per shift, and about 2 to 6 times for shearing 6,000 pieces per shift;

[0041] 5. End face inclination angle α = measurement angle a-90°

[0042] The detection tool designed in this embodiment is durable, easy to use and operate, and has low cost, and can play a great role in quality control of mass production.

[0043] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or replacements within the technical scope disclosed in the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
