[0001] The utility model relates to the technical field of hot forming part processing, in particular to a correction tool for quickly correcting the local size of a hot forming part. Background Art

[0002] In 1977, hot stamping technology was invented in Sweden. Hot stamping is referred to as hot forming. The hot forming steel plate (tensile strength of about 550MPa) is heated to above 900℃ in a heating furnace. The metallographic structure of the steel plate is transformed into austenite under high temperature. After the steel plate is heated and taken out of the furnace, it is stamped into shape at high temperature through a hot forming mold with a water cooling system. After forming, the mold is quickly cooled to below 100℃. The high-temperature austenite structure is transformed into martensite, which increases the tensile strength of the parts to more than 1300MPa. This process is the hot forming process.

[0003] When performing matching analysis on vehicle body assemblies, it is necessary to manually correct the dimensions of the hot-formed parts for dimensional analysis and verification of the assembly. Due to the high strength of hot-formed parts, it is difficult to achieve the expected results when using general conventional tools to correct the dimensions of the hot-formed parts. Currently, the tools for correcting the dimensions of the main matching areas (edge ​​parts) of hot-formed parts are basically conventional tools such as pliers and wrenches, and there are no special tools.

[0048] The fixed wrench 11 and the adjusting wrench 12 respectively have an integrally formed handle 13 and a mounting seat 14;

[0049] The mounting seat 14 is formed with a clamping groove 15 along its length direction for clamping parts;

[0050] The adjusting wrench 12 rotates along the connecting shaft 2 to deform the edge of the part located in the clamping groove 15 so as to correct the size of the part;

[0051] The adjusting wrench 12 is moved along the length direction of the connecting shaft 2 to clamp different correction positions of the parts.

[0052] Specifically, a correction tool for quickly correcting the local size of a hot-formed part, the correction tool comprises a fixed wrench 11 and an adjusting wrench 12, the fixed wrench 11 and the adjusting wrench 12 have the same structure (different sizes), the fixed wrench 11 and the adjusting wrench 12 both have a handle 13 and a mounting seat 14, the handle 13 is used for grasping during manual correction, and the mounting seat 14 is used for mounting the part to be processed, wherein a clamping groove 15 is formed on the mounting seat 14, the edge of the part is located in the clamping groove 15, and the part to be corrected is located in the clamping groove 15 on the adjusting wrench 12, the edge of the part is deformed by turning the adjusting wrench 12, thereby correcting the part, the adjusting wrench 12 is movably connected to the connecting shaft 2, the adjusting wrench 12 can rotate on the connecting shaft 2, and can also move along the connecting shaft 2, the adjusting wrench 12 can clamp different positions of the part during the movement, thereby correcting different parts of the part;

[0053] When in use, the fixed wrench 11 of the tool and the clamping groove 15 of the adjusting wrench 12 are put on the edge of the part to be corrected. The edge of the part is the overlapping area with other parts (stamping parts). This area is the key control area for matching. After the clamping groove 15 is put on the edge of the part, the adjusting wrench 12 is twisted up and down to deform the part to correct the size of the area. The adjusting wrench 12 can move along the length direction of the connecting shaft 2. The distance between the fixed wrench 11 and the adjusting wrench 12 is adjusted to adjust different positions. During actual adjustment, the position of the broken piece will be appropriately adjusted according to the deviation of the size.

[0054] The mounting seat 14 forms a U-shaped mounting groove 141;

[0055] A clip 142 is installed in the U-shaped clip groove 141;

[0056] A clamping groove 15 is formed between the two groups of clamping pieces 142 .

[0057] Threaded holes 143 are provided on both side walls of the mounting base 14;

[0058] The mounting bolt is placed in the threaded hole 143 and against the clip 142;

[0059] A gasket 3 is installed at the bottom between the two sets of clips 142;

[0060] The clip 142 is clamped and fixed by bolts and gaskets 3 , and the width of the clip groove 15 can be adjusted by screwing the bolts and replacing the thickness of the gaskets 3 .

[0061] Specifically, a U-shaped mounting groove 141 is formed above the mounting seat 14, and two groups of clips 142 are installed in the U-shaped mounting groove 141. The space between the two groups of clips 142 is the clip groove 15, wherein the size of the clip groove 15 is adjustable, that is, the position of the clip 142 is adjustable, specifically, threaded holes 143 are opened on the two side walls of the mounting seat 14, that is, the two side walls of the U-shaped clip groove 141, the clip 142 is located inside the U-shaped clip groove 141, and bolts are screwed into the U-shaped clip groove 141 from the outside of the threaded holes 143. The more the bolts enter the U-shaped clip groove 141, the more the two groups of clips are pushed. The plates 142 move towards each other, making the groove 15 between the two groups of clips 142 smaller, and the size of the installed parts becomes smaller. Conversely, the bolts are screwed outward so that the clips 142 can move toward the side wall of the U-shaped groove 141, and the two groups of clips 142 move away from each other, making the groove 15 between the two groups of clips 142 larger, and the size of the installed parts also becomes larger. At the same time, gaskets 3 are installed between the grooves 15, and the gaskets 3 are supported between the two groups of clips 142, which can not only stabilize the position of the clips 142, but also cooperate with the adjustment of the size of the groove 15 to adapt to the installation of stamping parts with different material thicknesses.

[0062] The connecting shaft 2 is inserted and installed on the mounting seat 14 and is located below the U-shaped mounting groove 141 .

[0063] Specifically, a U-shaped installation groove 141 is provided above the installation seat 14 , and a certain thickness is provided below the installation seat 14 to facilitate insertion and installation of the connecting shaft 2 .

[0064] The length of the mounting base 14 for fixing the wrench 11 is a;

[0065] The length of the mounting base 14 of the adjustment wrench 12 is b;

[0066] a≥2b.

[0067] Specifically, according to the shape of the parts, the lengths of the fixed wrench 11 and the adjusting wrench 12 vary (the lengths of their mounting bases 14), but the length of the fixed wrench 11 must be more than twice that of the adjusting wrench 12, so as to ensure that when the adjusting wrench 12 moves the parts, the part clamped by the adjusting wrench 12 can be deformed.

[0068] A jackscrew is installed on the connecting shaft 2 extending to both ends of the fixed wrench 11 to fix the position of the fixed wrench 11.

[0069] Specifically, the fixed wrench 11 and the adjusting wrench 12 are connected through the same connecting shaft 2. The difference is that the adjusting wrench 12 is movably connected to the connecting shaft 2, and the adjusting wrench 12 can rotate on the connecting shaft 2. The fixed wrench 11 is fixedly connected to the connecting shaft 2, and the connecting port of the fixed wrench 11 and the connecting shaft 2 is fixed by a top screw. The position of the fixed wrench 11 is fixed, which is convenient for the adjusting wrench 12 to forcefully pry parts, thereby avoiding random movement of parts and causing correction errors.

[0070] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
