Referring to fig. 2 and 4, a shape correction heat treatment tool structure for a sheet metal part according to an embodiment includes a lower die 1, an upper die 3 disposed on the lower die 1, and a clamping unit capable of detachably connecting the upper die 3 and the lower die 1 into a whole; the upper and lower opposite surfaces of the upper die 3 and the lower die 1 are planes for clamping the sheet part and keeping the flatness of the sheet part, and a groove 4 for giving way to the convex shape on the sheet part is processed on any one plane of the upper and lower opposite surfaces of the upper die 3 and the lower die 1.
Referring to fig. 5, when the structure of the sheet metal part sizing heat treatment tool of the embodiment is used, a sheet metal part 100 subjected to sheet metal bending is placed between an upper die 3 and a lower die 1, the number of the sheet metal part can be a plurality (the grooves 4 are correspondingly arranged), the sheet metal part is generally placed on the upper surface of the lower die 1, the convex shape formed by bending on the sheet metal part 100 falls into the receding groove 4, two opposite planes of the upper die 3 and the lower die 1 are clung to and clamping a sheet part with flatness requirement on the metal sheet part 100, at the moment, the tool is in a shape correction working state, after the clamping unit clamps and keeps the integrated shape correction working state, the whole body can be put into a vacuum furnace for heat treatment of twice circular heating, after the furnace is opened and the part is taken out, the tool is opened to take out the metal sheet part 100, and the flatness of the sheet part with flatness requirement reaches the form and position tolerance requirement (can be effectively controlled within 0.04 mm). The quantity of clamping parts between the upper die 3 and the lower die 1 is increased adaptively, and the qualification rate and the production efficiency of products in batch production can be effectively improved.
It should be noted that the two "planes" of the upper die 3 and the lower die 1 which are opposite to each other are not necessarily one plane, but may be two or more planes having an included angle depending on the bent shape of the part, that is, it is understood that the upper and lower opposite faces of the upper die 3 and the lower die 1 have planes corresponding to the sheet portions of the sheet part and are used for holding the sheet part to maintain the flatness thereof.
With reference to fig. 4-6, the groove 4 is opened on the upper surface of the lower mold 1 to play a positioning role when a thin sheet part is placed on the upper surface of the lower mold 1, so as to facilitate the fastening of the upper mold 3, and there is no requirement for alignment when the upper mold 3 is fastened.
When the method is implemented, the upper die 3 and the lower die 1 are both square plate-shaped structures and are convenient to process, the material can be selected from No. 45, the materials are used after hardening and tempering, the upper surface and the lower surface are both subjected to flat grinding by adopting a surface grinding machine to ensure the flatness (within 0.02 mm), and then a groove 4 is processed on the upper surface of the lower die 1; other suitable materials can be selected for design and use on the principle that deformation is not easy to occur during the subsequent shaping heat treatment.
The lower surface of the upper die 3 is provided with a convex part 5 corresponding to the concave shape of the sheet part, and the convex part 5 and the groove 4 are arranged up and down oppositely.
In this way, the topography of the location of the bent bead on the sheet metal part 100 may be better maintained during the heat treatment process.
Because the lower surface of the upper die 3 is provided with the convex part 5, the alignment requirement is met when the assembly is buckled, and the convex part 5 is required to accurately fall into the concave shape on the sheet part and cannot crush the sheet part of the part. Therefore, two guide posts 11 are vertically and convexly arranged on the upper surface of the lower die 1, and the two guide posts 11 freely penetrate through two corresponding guide holes 21 arranged on the upper die 3. Generally, the two guide posts 11 are located at two pairs of angular positions on the upper surface of the lower die 1. Thus, the accurate buckling of the upper die 3 can be ensured. The material of the guide post 11 can be selected from T8A, and after HRC30-35 is tempered, the guide post is fixedly connected to the lower die 1 for use.
With continuing reference to fig. 3-5, the clamping unit includes two opposite door-shaped buckles 7, the two door-shaped buckles 7 are respectively located on two sides of the upper die 3 and the lower die 1, the door-shaped buckle 7 comprises a vertical web plate 71, an upper flange 72 and a lower flange 73 which are respectively vertically connected with the upper edge and the lower edge of the web plate 71 and have the same orientation are in a shape similar to a channel steel, i.e., gate type, the lower surface of the upper flange 72 and the upper surface of the lower flange 73 are opposed to each other and are two inclined surfaces 74 gradually distant from each other in a direction toward the free ends, the upper die 3 and the lower die 1 are located between the upper flange 72 and the lower flange 73, the web 71 is provided with a through hole 75, a bolt 10 penetrates through the through hole 75, and a screw section of the bolt 10 penetrates through the through hole 75 and is in threaded connection with an internal thread formed on the side surface of the upper die 3 or the lower die 1 so as to enable the upper die 3 and the lower die 1 to be wedged between the upper flange 72 and the lower flange 73 by screwing the bolt 10, thereby realizing detachable clamping connection.
Thus, the upper die 3 and the lower die 1 can be reliably attached and clamped to the sheet part with flatness requirement on the sheet part 100 by wedge acting force, and the final form and position tolerance requirement is ensured to be met.
Wherein, the upper surface of the upper die 3 and the lower surface of the lower die 1 are respectively provided with a wedging inclined surface 8 corresponding to the two inclined surfaces 74.
Like this, the wedging effort can be acted on and mould 3 and lower mould 1 better, also avoids going up the border of mould 3 and lower mould 1 and is damaged by the wedge, door type buckle 7 and last mould 3 and lower mould 1's separation when also convenient to detach simultaneously.

Thus, the situation that the lower flange 73 protrudes out of the lower surface of the lower die 1 to cause uneven placement or difficult and stable placement is avoided.
Because the notch 12 that gives way needs to be set up and the holding bottom flange 73, the thickness increase of lower mould 1 probably influences the heat treatment effect of centre gripping foil part 100, so recessed heat conduction groove 13 is seted up to the lower surface of lower mould 1, heat conduction groove 13 is located the notch 12 that gives way of lower mould 1 both sides, heat conduction groove 13 is parallel to two notches 12 that give way and both ends run through lower mould 1 and set up. Thus, the heating and cooling uniformity in the heat treatment process can be ensured as much as possible.
Since the inclined surfaces 74 of the upper and lower flanges 72, 73 require a certain overlap travel (laterally) in cooperation with the corresponding wedging inclined surfaces 8, screwing in and out the bolt 10 is time consuming and laborious if each assembly and disassembly relies entirely on screwing in and out the bolt 10. Therefore, an opening washer 9 is clamped between the head of the bolt 10 and the outer side surface of the web 71, the opening washer 9 is provided with a through hole which is sleeved on the corresponding screw section of the bolt 10, the opening washer 9 is also provided with a through opening 91 along the radial direction, namely, the opening 91 penetrates from the through hole to the outer circumferential surface of the opening washer 9, the width of the opening 91 corresponds to the inner diameter of the through hole, so that the gasket can be conveniently inserted and taken out, correspondingly, when the die is disassembled, only the bolt 10 needs to be unscrewed, the opening washer 9 is withdrawn along the radial direction through the opening 91, and the door-shaped buckle 7 can be withdrawn and kept away from the upper die 3 and the lower die 1, so that the die; the assembly is performed reversely, and is not described in detail.

Furthermore, a plurality of layer-adding structures 2 are clamped between the upper die 3 and the lower die 1, the layer-adding structures 2 are also plate-shaped with upper and lower surfaces parallel, the upper surfaces of the layer-adding structures 2 correspond to the upper surface of the lower die 1, namely, grooves 4 are also formed, and the lower surfaces of the layer-adding structures 2 correspond to the lower surface of the upper die 3, namely, protrusions 5 are also formed; the two guide posts 11 also freely pass through the two corresponding guide holes 21 formed in the layer-adding structure 2, in this embodiment, three layer-adding structures 2 are illustrated, so that a total of 5 × 6 × 4 pieces of sheet metal parts 100 can be clamped into the furnace at each time, and the production efficiency is further improved on the basis of improving the yield.
Due to the addition of the layer-adding structure 2, the screw section of the bolt 10 is connected to the side face of the layer-adding structure 2 in the middle after passing through the through hole 75, so that the upper and lower stress is more balanced.
During actual processing, the upper die 3 and the layer adding structure 2 are the same piece so as to facilitate processing and circulation, only one layer adding structure 2 is selected randomly after processing is finished to be used as the upper die 3 on the top layer, and correspondingly, a process of processing the wedging inclined plane 8 on the upper die 3 is added.
