Embodiment 1

[0034] see Figure 1 to Figure 5 , the figure shows a stamping die with an in-mold tapping deviation correction structure provided by Embodiment 1 of the present invention, which includes:

[0035] The upper mold mechanism 1 includes an upper mold base 11 and a plurality of floating pressing mechanisms 12, and the floating pressing mechanism 12 includes an inverted nitrogen gas spring 121, an inverted ejector block 122, and a strip positioning and adjusting block 123, an inverted nitrogen gas spring 121 Fixedly installed on the upper mold base 11, the anti-jacking block 122 is connected with the anti-jacking nitrogen spring 121, the material belt positioning and adjusting block 123 is fixedly connected with the anti-jacking block 122, and the bottom of the material belt positioning and adjusting block 123 has a function to hold down the material belt 13. The positioning notch 124 is provided with an elastic step surface 125 for adjusting the positioning of the material belt an...

Embodiment 2

[0050] see Figure 1 to Figure 5 , the figure shows a stamping die with an in-mold tapping deviation correction structure provided by Embodiment 2 of the present invention. This embodiment further makes the following technical solutions as improvements on the basis of the above embodiments: The belt positioning and adjusting block 123 is a rectangular block, and the positioning notch 124 is a rectangular notch located on the bottom corner of the rectangular block, and the elastic step surface 125 is L-shaped in a plan view. Through the setting of the above structure, the shape of the corner of the material strip can be adapted to ensure the stability of positioning.

Embodiment 3

[0052] see Figure 1 to Figure 5 , the figure shows a stamping die with an in-mold tapping deviation correction structure provided by Embodiment 3 of the present invention. This embodiment further makes the following technical solutions as improvements on the basis of the above embodiments: L The L-shaped positioning adjustment block 222 is rotatably connected in the notch 221 through a pin 225 , and an elastic pad 226 is provided between the bottom of the L-shaped positioning adjustment block 222 and the notch 221 . Through the setting of the above structure, the effect of buffering and eliminating the vibration of the L-shaped positioning adjustment block on the tapping machine can be formed, and the stability of the installation of the L-shaped positioning adjustment block can be ensured. At the same time, the rotatable feature of the L-shaped positioning adjustment block can be easily removed. shape positioning adjustment block.

Abstract

The invention provides a stamping die with an in-die tapping deviation rectifying structure. The stamping die comprises: an upper die mechanism, wherein the bottom of a material belt positioning and adjusting block is provided with a positioning notch for pressing a material belt, the positioning notch is internally provided with an elastic step face used for adjusting the downward pressure of thematerial belt positioning and adjusting block, and a tapping head of a tapping machine is located between every two adjacent floating material pressing mechanisms; a lower die mechanism, wherein notches are further machined in the two opposite ends of a lower base plate, movable L-shaped positioning adjusting blocks are installed in the notches, a machine body of the tapping machine is positionedin the notches, comb tooth structures are machined in steps of the L-shaped positioning adjusting blocks, comb tooth inserts are arranged on the machine body, and the comb tooth inserts and the combtooth structures are meshed with each other. The invention further provides a deviation rectifying method. Compared with the prior art, the problems of missing tapping, tooth hole deviation, incomplete tapping and the like of tapping in an inner die of an existing stamping die can be effectively solved, and especially the phenomena of tooth hole deviation and tooth hole burning are avoided.

Description

technical field [0001] The invention relates to the field of stamping dies, in particular to a stamping die with an in-mold tapping deviation correction structure and a deviation correction method. Background technique [0002] At present, in the entire stamping industry, problems such as missed tapping in the mold, deviation of the tooth hole, unpunctured teeth, and incomplete tapping have always been a problem that has not been completely solved in the stamping industry, because in the entire automotive industry, troublesome The tapping parts involved are almost always installed in very important parts such as mechanism parts, safety parts, and door locks. If the quality of these tapping parts is abnormal, it will bring great losses to personal safety and property safety. For factories and automobile OEMs, it is directly related to model recalls and damage to corporate brand image. [0003] Therefore, at present, the stamping industry must solve problems such as missed ta...
