The invention provides a stamping die capable of keeping pressing leftover material parts of plates. The stamping die comprises an upper die seat and a lower die seat. A convex die is arranged at thelower end of the upper die seat, and a concave die is arranged at the upper end of the lower die seat. Multiple pressing devices are evenly distributed on the upper die seat with the convex die as thecenter. Each pressing device comprises a base, a press plate below the base and multiple pressing mechanisms between the base and the press plate. A press pad is arranged on the lower end face of each press plate. A concave cavity is arranged at the lower end of the upper die seat, and a base body of the convex die is mounted in the concave cavity and is fixed by a locating pin mounted on the upper die seat. The structural design of the stamping die is reasonable; and through the arranged pressing devices, in the stamping process, the leftover material parts of the plates are kept being pressed, leftover materials are prevented from rebounding, and the effect is remarkable. The convex die is fixed to the upper die seat through the locating pin, demounting and replacement can be facilitated, universality is good, the locating pin only achieves a locating function and does not achieve the function of mainly bearing stamping loads, the structure stability is good, and the service life islong.

The embodiment of the invention provides a vacuum superconducting electric heater and a manufacturing method thereof. The vacuum superconducting electric heater comprises a heating rod and radiating fins, wherein each radiating fin is in a flaky shape; each radiating fin comprises two cover plates which are buckled together and in welding connection; and grooves on the two cover plates form heat conducting cavities after the two cover plates are buckled together. The manufacturing method comprises: making the cover plates by using a stamping process, and forming a plurality of grooves on the cover plates; buckling the two cover plates and welding the edges of the two cover plates to form a flaky radiating fin, wherein the plurality of grooves on the two cover plates form a plurality of heat conducting cavities after the two cover plates are buckled, and the plurality of heat conducting cavities in one radiating fin are communicated through a gap between the cover plates; and welding the interfaces of the radiating fins to connect the adjacent radiating fins. The radiating fins are arranged in a flaky shape, so that the heat dissipating areas of the radiating fins are increased and the heat dissipating efficiency is improved.

The invention discloses a working method of a mobile phone lens support frame continuous punching die. Step 1), firstly punching equidistant side holes after metal sheet materials enter into a stamp die; Step 2), conducting outer shape die cutting after the metal sheet materials move forward one position; Step 3), conducting pre-molding stamping after the metal sheet materials move forward one position; Step 4), conducting middle hole thick die cutting after the metal sheet materials move forward one position; Step 5), conducting scrap chopper die cutting after the metal sheet materials move forward one position; Step 6), conducting fine molding stamping after the metal sheet materials move forward one position; Step 7), conducting half-cutting die cutting after the metal sheet materials move forward one position; Step 8), conducting finished product discharge die cutting after the metal sheet materials move forward one position. Accordingly, the working method of the mobile phone lens support frame continuous punching die is simple and practical in structural design, convenient to install and adjust, and continuous stamping process is conducted effectively and rapidly to a mobile phone lens support frame by using the mobile phone lens support frame continuous punching die, and thus the motion speed of a whole mechanism and the production efficiency of a machine are improved.

The invention discloses a backboard quality control method, which relates to computer, display, TV, mobile phone, copier and other optoelectronic product components and accessories, and is used to solve the problem of how to control the key quality characteristics of the backboard and avoid any drying remaining at the drilled hole. The problem of impurities. It includes step 1, incoming material inspection; step 2, receiving materials; in the second step, receiving materials is divided into two links, S1, stamping process self-inspection; S2, IPQC random inspection; step 3, cleaning; step 4, packaging ; In the step 4, the packaging is divided into two links, Y1, packaging process; Y2, IPQC random inspection; step 5, warehousing inspection; step 6, shipment. Improve the pass rate of products by improving the intermediate links of quality control.

The invention discloses a fully parametric drawing mould design method, which enables the design of a mould structure to be more reasonable and realizes the parameterization, the high speed and the intellectualization of the drawing mould design process. The invention has the technical scheme that the method comprises the following steps of stamping process pretreatment: processing process data, and directly obtaining a mould structure design element by combining with a mould design standard; mould structure design: aiming at the design of the non molded surface part of a model to carry out associated design to a mould structure parameter during solid modeling so as to bring convenience for the model to automatically change when a corresponding parameter is changed.

The invention relates to a stamping process for a large-table-board stamping device of metal sheet stamping and cutting automation equipment. The large-table-board stamping device of the metal sheet stamping and cutting automation equipment consists of a servo motor, a speed reducer, a drive wheel, a synchronous belt, a driving wheel, an upper fixing plate, a beating plate and a beating seat; a power guide box is arranged on the beating plate; the beating seat is correspondingly arranged in the power guide box; the inner side of the power guide box and the outer side of the beating seat are correspondingly arranged; the servo motor drives the speed reducer; the speed reducer drives the synchronous belt by the drive wheel by reducing the rotating speed and magnifying the power and is in linkage with the driving wheel; the driving wheel drives a beating mechanism between the beating seat and the beating plate, so as to further drive the beating plate to carry out downward stamping for realizing stamping of 500/min, 300 K.N; the efficiency is improved, the energy consumption is reduced, the human and equipment input is reduced, the automation of the production process is realized, the processing stability is achieved, the consistency is good, and energy consumption and emission reduction are achieved; the stamping process can be used for batch processing of sheet metal parts like steel furniture, steel cabinets and electric appliance cabinets.
