Embodiment 1

[0030] see Figure 1 to Figure 3 , the figure shows a stamping die with an adaptive cooling mechanism provided by Embodiment 1 of the present invention, which includes:

[0031] 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 gap 124 is provided with an elastic step surface 125 for adjusting the positioning of the material belt and the downward pressur...

Embodiment 2

[0043] see Figure 1 to Figure 3 , the figure shows a stamping die with an adaptive cooling mechanism provided by Embodiment 2 of the present invention. On the basis of the above embodiment, this embodiment further makes the following technical solutions as improvements: Tapping head 51 is provided with a floating nut 4 at the connection position with the tapping machine, and the floating nut 4 is eccentrically sleeved on the connecting shaft of the tapping machine through a spring, and the floating nut 4 is connected to the driving wheel by transmission, and the driving wheel is connected to the micro motor; When performing deviation correction, the micro motor starts and drives the floating nut to rotate, and the floating nut drives the tapping head 51 to return to the vertical position or to the concentric position with the tapping groove 27, during which the tapping tap in-position sensor continuously detects the tapping head 51 position, until the tapping head 51 is adjus...

Embodiment 3

[0045] see Figure 1 to Figure 3 , the figure shows a stamping die with an adaptive cooling mechanism provided by Embodiment 3 of the present invention. On the basis of the above embodiment, this embodiment further makes the following technical solutions as improvements: strip positioning And the 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.

Abstract

The invention provides a stamping die with an adaptive cooling mechanism. The stamping die with the adaptive cooling mechanism comprises an upper die mechanism and a lower die mechanism, wherein bothopposite sides of a lower die seat are provided with two first oil gas pipeline mounting frame, and the first oil gas pipeline mounting frames are internally and fixedly provided with an oil path inlet pipe and a gas path inlet pipe in a penetrating mode. The oil path inlet pipe is connected with an oil pipe, the gas path inlet pipe is connected with a gas pipe, and the outlet of the oil pipe andthe gas pipe converge on an oil-gas outlet pipe. The oil-gas outlet pipe obliquely penetrates through second oil gas pipeline mounting frames, wherein the second oil gas pipeline mounting frames are elastically connected to a lower plate, the outlet of the oil-gas outlet pipe extends obliquely towards the direction of a tapping head, and the oil-gas outlet pipe and a horizontal plane form an included angle of 48 degree-68 degree. The invention further provides a cooling method. Compared with the prior art, the problems of incomplete cooling and uniform cooling in an operation area when die tapping is carried out inside the stamping die can be solved, and accordingly the cooling effect is effectively improved.

Description

technical field [0001] The invention relates to the field of stamping dies, in particular to a stamping die with an adaptive cooling mechanism and a cooling method. Background technique [0002] At present, in the entire stamping industry, the in-mold tapping cooling system has been troubled by manufacturers, especially in auto parts manufacturers. Now all auto parts are made of high-strength steel plates or even ultra-high-strength steel plates. There are some tapping products in the lock system. In order to improve production efficiency, most of the products now change the traditional single-process mold to progressive die production. Progressive die production adds in-mold tapping equipment to realize product turning and tapping. The teeth are completed together in the mold, but when the product enters the tapping process after turning the hole, it often occurs that the teeth are burnt in the hole, and the temperature of the tap is too high and the wear is accelerated, wh...
