Description

Technical Field

[0001] This utility model relates to the field of positioning tooling technology, and in particular to an adjustable billet positioning device. Background Technology

[0002] With the continuous improvement of product quality standards, the reliability of blank positioning devices in stamping dies has become increasingly critical. However, the company's current production situation requires that the same die not only meet the production needs of one or two conventional products, but also be compatible with the dimensional requirements of various non-standard orders; therefore, fixed-position positioning devices cannot meet these needs. Although traditional adjustable positioning devices can be flexibly adjusted using bolts, shims, and oblong holes, in the mass production of conventional products, the frequent impact of the blank on the positioning device can easily cause it to loosen or shift. This not only increases the workload of inspection and calibration for each batch of products, consuming time and resources, but also affects the stability and consistency of product dimensions, reducing production efficiency.

[0003] To solve the above problems, an adjustable billet positioning device was designed. Utility Model Content

[0004] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, one objective of this invention is to propose an adjustable billet positioning device that enables rapid positioning, has strong applicability, and is easy to adjust.

[0005] The adjustable billet positioning device according to the present invention includes a mold body, wherein a positioning device mounting groove is provided on the surface of the mold body, and a billet positioning device is provided inside the positioning device mounting groove.

[0006] The mounting groove has fixing screw holes and multiple positioning pin holes arranged in a straight line inside.

[0007] The blank positioning device includes a positioning block body. The surface of the positioning block body is provided with a waist hole and a pin hole. A fixing screw is movably fitted inside the waist hole. A spring washer and a flat washer are sequentially fitted vertically downward on the surface of the fixing screw. A cylindrical pin is fitted inside the pin hole, and one end of the cylindrical pin extends out from the pin hole.

[0008] Preferably, the surface of the mold body is provided with a material-bearing surface, and a blank plate is placed on the surface of the material-bearing surface.

[0009] Preferably, the side of the positioning block body is provided with a positioning surface, which contacts the side wall of the blank plate.

[0010] Preferably, the length of the waist hole is greater than the distance between the outermost positioning pin holes.

[0011] Preferably, the fixing screw is threaded into the fixing screw hole, and the spring washer and flat washer are placed between the fixing screw and the positioning block body.

[0012] Preferably, the cylindrical pin and the plurality of positioning pin holes are located in the same vertical plane.

[0013] The beneficial effects of this utility model are:

[0014] 1. During the production of regular products, it can quickly switch between one or more gears and provide relatively stable rigid limits to ensure the stable and reliable positioning dimensions of the material stop device.

[0015] 2. When producing non-standard products, it can switch to the working mode of the traditional adjustable positioning device, and use the waist-shaped hole structure to adjust to any size within the range, resulting in high product compatibility.

[0016] 3. Whether switching between fixed gears of conventional products or adjusting to any size required for non-standard products, this device can achieve this by simply removing and installing a single bolt. There is no need to replace or add other components, nor is there a need to prepare other spare parts for switching. This results in high production changeover efficiency and low production management burden. Attached Figure Description

Detailed Implementation

[0023] Reference Figure 1-5 An adjustable blank positioning device includes a mold body 2, a positioning device mounting groove 201 is provided on the surface of the mold body 2, and a blank positioning device 3 is provided inside the positioning device mounting groove 201.

[0024] The mounting slot has a fixing screw hole 203 and a number of positioning pin holes 204 arranged in a straight line inside;

[0025] The blank positioning device 3 includes a positioning block body 31. The surface of the positioning block body 31 is provided with a waist hole 36 and a pin hole 311. A fixing screw 33 is movably installed inside the waist hole 36. A spring washer 34 and a flat washer 35 are installed vertically downward on the surface of the fixing screw 33. A cylindrical pin 32 is installed inside the pin hole 311, and one end of the cylindrical pin 32 extends out from the pin hole 311.

[0026] The surface of the mold body 2 is provided with a material-bearing surface 202, and a blank plate 1 is placed on the surface of the material-bearing surface 202.

[0027] The positioning block body 31 has a positioning surface 312 on its side, and the positioning surface 312 is in contact with the side wall of the blank plate 1.

[0028] The length of the waist hole 36 is greater than the distance between the outermost positioning pin holes 204. When positioning a regular product, it is necessary to adjust the cylindrical pin 32 to align with the positioning pin holes 204 at different positions according to the product specifications. It is necessary to ensure that the fixing screw 33 is still located inside the waist hole 36 when the extreme alignment position is reached, so as to ensure the stability of the two-point positioning.

[0029] The fixing screw 33 is threaded into the fixing screw hole 203. The spring washer 34 and the flat washer 35 are placed between the fixing screw 33 and the positioning block body 31. The spring washer 34 is installed to adapt to the pressing pressure and prevent the positioning block body 31 from putting too much pressure on the product surface and causing damage to the product surface.

[0030] The cylindrical pin 32 and multiple positioning pin holes 204 are in the same vertical plane. When positioning different conventional products, it is necessary to adjust the cylindrical pin 32 to the appropriate positioning pin hole 204 according to the size of the conventional product, and ensure that the docking position is aligned.

[0031] When using this device, there are two types of positioning: standard product positioning and non-standard product positioning.

[0032] Positioning of conventional products: See Figure 4In this embodiment, positioning pin holes 204A and 204B are provided. Taking two standard product sizes as examples, according to the type of product, the corresponding hole position is selected from positioning pin holes 204A or 204B. After inserting the cylindrical pin 32 into the pin hole 311, the positioning block body 31 is fixed in the positioning device mounting groove 201 with fixing screws 33, spring washers 34 and flat washers 35, thus completing the installation of this device. During product production, the blank plate 1 is placed on the material receiving surface 202 on the mold body 2 and pushed until it is aligned with the positioning surface 312 on the blank positioning device 3, thus completing the positioning of the blank plate 1.

[0033] Positioning of non-standard products: See Figure 5 When non-standard products need to be produced, first flip the positioning block body 31 so that the cylindrical pin 32 is embedded in the positioning block body 31 with one side facing the positioning device mounting groove 201. Then reinstall the fixing screws 33, spring washers 34, and flat washers 35. At this time, the positioning block body 31 can be adjusted arbitrarily within the range of the oblong hole. After adjusting the position of the positioning surface 312 with the help of calipers or tape measure, tighten the fasteners to ensure that the positioning block body 31 is fixed in the positioning device mounting groove 201. Finally, align the blank plate 1 with the positioning surface 312 on the blank positioning device 3, and the production of non-standard products can begin.
