Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of punching equipment, in particular to a large forging punching centering auxiliary device. Background Art
[0002] Punching forgings requires heating to the punching temperature to reduce the material's strength and hardness, making them easier to process. For large forgings, the temperature during punching ranges from 1000-1200°C, making it difficult for operators to approach closely. Operators can only observe from a distance to determine whether the punch is aligned with the center of the blank. This long-distance alignment prevents the operator from clearly observing the punch's position relative to the blank, and their line of sight is easily disturbed, affecting punching accuracy. If the punching error is large, the punch center deviates from the center of the blank, known as offset. This results in uneven wall thickness after punching, impacting subsequent production and potentially even causing the blank to become scrapped.
[0003] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute prior art known to ordinary technicians in the field. Utility Model Content
[0004] In view of the above shortcomings of the prior art, the purpose of the present invention is to provide a large forging punching centering auxiliary device to assist operators in centering the forging when punching.
[0005] The technical solution of the utility model is as follows:
[0006] A large forging punching centering auxiliary device includes: a sleeve part, which is sleeved on a punch; a benchmark rod, which is connected to the sleeve part; a calibration part, which is arranged on the benchmark rod, and the calibration part is perpendicular to the benchmark rod; wherein, when the sleeve part is arranged on the punch, the benchmark rod is perpendicular to the axis of the punch; at least three benchmark rods are provided, and each of the benchmark rods is provided with a calibration part, and the calibration part is vertically downward close to the outer circumference of the workpiece.
[0007] Furthermore, a calibration seat is further included, which is slidably arranged on the benchmark rod, and the calibration member is vertically connected to the calibration seat and slides along the benchmark rod.
[0008] Furthermore, a screw is provided on the calibration seat; when the screw is tightened, the calibration seat is restricted on the benchmark rod.
[0009] Furthermore, the pole is provided with a scale.
[0010] Furthermore, the calibration member is a chain.
[0011] Furthermore, during punching, the lower end of the calibration piece passes over the upper surface of the workpiece before the lower surface of the punch.
[0012] Furthermore, a threaded hole is formed on the sleeve, and the marking rod includes a threaded section, and the threaded section is screwed into the threaded hole.
[0013] Furthermore, the calibration piece is made of high temperature resistant material.
[0014] The beneficial technical effects of the present utility model are as follows:
[0015] (1) The large forging punching centering auxiliary device in the present invention is provided with a benchmark and a calibration piece. When the forging is ready for punching, the sleeve is fixed on the punch to mark the position of the benchmark and the calibration piece. The calibration piece is adjusted to the position of the punch equal to the radius of the workpiece. When punching, the operator only needs to observe the relative position of the calibration piece and the workpiece to ensure that the three calibration pieces are all on the outer circumference of the workpiece to determine whether the punch is aligned with the center of the workpiece. Compared with observing the relative position of the punch and the workpiece, directly judging whether the three calibration pieces are all on the circumference of the workpiece is clearer and the operator can make a judgment at a certain distance, thereby reducing the error of punching deviation during punching.
[0016] (2) Furthermore, a calibration seat is provided, which is slidably mounted on the reference rod and connected to the calibration piece. By sliding the calibration seat along the reference rod, the distance between the calibration piece and the sleeve piece can be quickly adjusted to accommodate forging holes of different sizes.
[0017] (3) Furthermore, when punching, the calibration piece passes over the punching surface, which more intuitively shows the relative position of the calibration piece and the workpiece, making it easier for the operator to judge whether the punch is aligned with the center position of the workpiece.

[0023] Example 1
[0024] Figure 1 The schematic diagram of the partial cross-section of the large forging punching centering auxiliary device of the utility model is shown. Figure 1 , a large forging punching centering auxiliary device, including a sleeve 1, a benchmark 2 and a calibration piece 4. The sleeve 1 is set on the punch 5. The benchmark 2 is connected to the sleeve 1. The calibration piece 4 is set on the benchmark 2, and the calibration piece 4 is perpendicular to the benchmark 2. The calibration piece 4 is a chain, and the chain is a flexible part. During actual use, it is only necessary to adjust the position of the calibration seat 3 on the benchmark 2, and there is no need to adjust the rotation angle of the calibration seat 3 around the benchmark 2. When the calibration seat 3 is at any angle around the benchmark 2, the calibration piece 4 of the flexible part will be vertically downward, that is, towards the direction of the workpiece 6 under the action of gravity, allowing the operator to observe the positional relationship between the calibration piece 4 and the workpiece 6. The calibration piece 4 is a chain, which is also convenient for folding and storage. Among them, when the sleeve 1 is set on the punch 5, the benchmark 2 is perpendicular to the axis of the punch 5, so that each benchmark 2 is located in the same plane. The calibration piece 4 is set on the benchmark 2, and the calibration piece 4 is perpendicular to the benchmark 2 due to its own weight. This allows the calibration pieces 4 on each marker 2 to be adjusted to the same distance, making it easier to find the center position of the workpiece 6 .
[0025] There are at least three reference rods 2, and each reference rod 2 is provided with a calibration piece 4, which is vertically downward and close to the outer circumference of the workpiece 6, and the distance between each calibration piece 4 and the sleeve piece 1 is the same. When the forging is ready for punching, the sleeve piece 1 is fixed on the punch 5 to determine the position of the reference rod 2 and the calibration piece 4. When punching, the operator only needs to observe the relative position of the calibration piece 4 and the workpiece 6 to determine whether the punch 5 is aligned with the center of the workpiece 6. When the workpiece 6 has a position deviation, adjust the position of the workpiece 6 to ensure that the three calibration pieces 4 are all on the outer circumference of the workpiece 6, and it can be determined that the center of the punch 5 and the center of the workpiece 6 are aligned. Compared with observing the relative position of the punch 5 and the workpiece 6, the present application directly observes whether the three calibration pieces 4 are all on the circumference of the workpiece 6. Since the observation position is close to the operator, the observation is clearer, thereby reducing the error of punching deviation during punching.
[0026] The specific structure of the calibration base 3 is described below:
[0027] The tool also includes a calibration seat 3, which is slidably mounted on the marking rod 2. A calibration member 4 is vertically connected to the calibration seat 3 and slides along the marking rod 2. By sliding the calibration seat 3 along the marking rod 2, the distance between the calibration member 4 and the sleeve member 1 can be quickly adjusted to accommodate forgings of different diameters.
[0028] Furthermore, a screw 31 is provided on the calibration seat 3. When the screw 31 on the calibration seat 3 is tightened, the screw 31 contacts and presses against the benchmark 2, thereby restricting the calibration seat 3 on the benchmark 2. The position of the calibration seat 3 on the benchmark 2 can be specified, thereby fixing the position of the calibration member 4 on the benchmark 2.
[0029] The specific structures of the set piece 1 and the calibration piece 4 are described below:
[0030] During punching, the lower end of the calibration piece 4 passes over the upper surface of the workpiece 6 before the lower surface of the punch 5. Specifically, the surface of the workpiece 6 close to the punch 5 is the punching surface, and the calibration piece 4 is adjusted to a predetermined position on the benchmark 2. When the punch 5 contacts the punching surface, the calibration piece 4 is close to the outer circumference of the workpiece 6. This makes it easier for the operator to judge whether the punch 5 is aligned with the center position of the workpiece 6. A threaded hole 11 is provided on the sleeve 1, and the benchmark 2 includes a threaded section 21. The threaded section 21 is screwed into the threaded hole 11, and the benchmark 2 and the sleeve 1 are threadedly connected. The threaded connection can provide a higher connection strength, is suitable for bearing larger loads, and is convenient for connection and disassembly, thereby simplifying the disassembly and assembly of the auxiliary device for punching and centering large forgings.
[0031] Furthermore, a scale 22 is provided on the rod 2, and the operator can use the scale 22 to easily determine the predetermined position of the calibration seat 3 and the calibration member 4 on the rod 2. The calibration member 4 is made of high-temperature resistant material, so that the calibration member 4 can withstand the temperature of the workpiece 6 when it is close to the high-temperature workpiece 6.
[0032] The specific workflow of this utility model is as follows:
[0033] Set the sleeve 1 on the punch 5, and connect the benchmark 2 and the sleeve 1 with threads. According to the outer radius of the workpiece 6, adjust the distance between the calibration seat 3 and the axis of the punch 5, and slide the calibration seat 3 to the predetermined position on the benchmark 2 through the scale 22. Then tighten the screw 31 to fix the position of the calibration seat 3 on the benchmark 2. When punching, the operator first observes the positional relationship between the outer circumference of the calibration piece 4 and the workpiece 6. If the positional relationship is the same, the punch 5 is aligned with the center point of the workpiece 6. At this time, the sleeve 1 is removed from the punch 5, the entire large forging punching centering auxiliary device is removed, and then the punching process can be carried out; if the positional relationship is inconsistent, adjust the horizontal position of the punch 5 and the workpiece 6 until the positional relationship between the calibration piece 4 and the outer circumference of the workpiece is consistent. At this time, the punch 5 is aligned with the center point of the workpiece 6, and then the sleeve 1 is removed from the punch 5, the entire large forging punching centering auxiliary device is removed, and then the punching process can be carried out.
[0034] Thus, with the aforementioned large forging punching centering aid, the operator only needs to observe the relative positions of the calibration pieces 4 and the workpiece 6 to ensure that all three calibration pieces 4 are on the outer circumference of the workpiece 6 to determine whether the punch 5 is aligned with the center of the workpiece 6. Compared to observing the relative positions of the punch 5 and the workpiece 6, directly determining whether all three calibration pieces 4 are on the circumference of the workpiece 6 is clearer and more straightforward. The operator can also make this judgment from a distance, thereby reducing the error caused by deviation during punching.
[0035] The technical features of the above embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0036] The above embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, and these variations and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
