The application discloses a punching process for a Mylar sheet, which solves the edge quality problem caused by uneven stress in traditional single-sided punching. The process realizes high-precision processing through double-sided synchronous punching and composite clamping positioning: after the Mylar sheet is introduced into the punching area by a conveying mechanism, the adsorption clamping mechanism is adsorbed and clamped by a negative pressure cavity and tensioned by an elastic pressure head, forming double positioning of center fixing and edge tensioning; the punch mechanism drives the asymmetric synchronous movement of the upper and lower punch heads through rack and pinion transmission, the lower punch head is driven to go down by the upper punch head, and the two punch heads meet and punch at the knife groove, so that the shearing force is symmetrically distributed on both sides of the material, and the unilateral bending moment effect is eliminated. The equipment adopts modular design, and the punch head and the adsorption box can be quickly replaced to adapt to different hole types. Through force field balance control and precise transmission, the process significantly reduces edge flanging and burrs, improves hole consistency, is suitable for precise Mylar sheet processing in the fields of electronics and electrical appliances, and has the advantages of high efficiency, stability, convenient type changing and the like.

This invention discloses a multi-effect synthesis apparatus and method for hydrogen sulfide synthesis. The apparatus has a vertical columnar structure, and its interior is arranged from bottom to top as follows: a first-effect liquid sulfur synthesis zone, a second-effect gas-liquid two-phase sulfur synthesis zone, a third-effect compensation synthesis zone, and a condensation and sulfur replenishment zone. The first-effect liquid sulfur synthesis zone is used for the main reaction of molten sulfur and hydrogen. The second-effect gas-liquid two-phase sulfur synthesis zone is used for the deep reaction of residual sulfur vapor and hydrogen. The third-effect compensation synthesis zone is used for the compensation catalytic synthesis of unconverted hydrogen and utilizes temperature drop to condense and reflux gaseous sulfur. The condensation and sulfur replenishment zone is equipped with a condensation coil for gradient cooling of the rising gas, causing gaseous sulfur to condense into liquid and fall for reuse. The top of the apparatus corresponding to the condensation and sulfur replenishment zone is equipped with a hydrogen sulfide gas outlet. This invention has the advantages of low energy consumption, high raw material conversion rate, high utilization rate of sulfur and hydrogen, and high purity of the produced hydrogen sulfide product.
