Abstract
The utility model relates to an optimized drawing die of a fuel injector part of an automobile engine, in particular to a stamping and drawing die device arranged between a punch-die positioned above the device and a blanking female die positioned below the device, wherein the blanking female die is provided with a blank holder and an ejector pin for the blank holder. The stamping and drawing die device is characterized in that the punch-die is provided with an upper die compression bar; a hole is formed in the position of the blanking female die corresponding to the upper die compression bar; the hole is matched with a pressure relief regulating rod in a sliding manner; a spring sleeve is mounted in the die center of the bottom of the blanking female die; a blank holder spring is arranged in the center of the spring sleeve; a backing plate is mounted at the bottom of the blank holder spring; and an air spring support plate and an air spring are fixed in the center of a worktable below a stamping device. The utility model mainly solves the technical problems that an elastic blank holder of the traditional drawing die commonly adopts a spring, rubber and an air spring, the blank holder force is increased along with the increase of the drawing depth, and a drawing piece is easy to break or become partially thinning out at the later period of drawing because of overlarge blank holder force; and furthermore, the stamping and drawing die device can optimize the drawing process and improve the part quality.
Description
Affiliated technical field
The utility model relates to a kind of optimization cupping tool of oil nozzle of car engine part, particularly a kind of punching press cupping tool device.
Background technology
The oil nozzle of car engine part is a stainless sheet steel drawing and forming part, surface quality and dimensional requirement height, and need repeatedly pull and stretch.The elastic blank holding coil apparatus of tradition cupping tool generally adopts spring, rubber and air spring, pressure-pad-force all strengthens along with the increase of drawing depth, this is very unfavorable to pull and stretch, produce fracture or local attenuation because pressure-pad-force is excessive at pull and stretch later stage drawing part easily, need to increase operation and could satisfy product requirement.
The utility model content
The purpose of this utility model is to provide a kind of punching press cupping tool device, the elastic blank holding coil apparatus that mainly solves traditional cupping tool generally adopts spring, rubber and air spring, pressure-pad-force all strengthens along with the increase of drawing depth, produce the technical problem of fracture or local attenuation easily because pressure-pad-force is excessive at pull and stretch later stage drawing part, it can optimize deep-drawing technique, improves part quality.
For achieving the above object, the utility model is achieved in that
A kind of punching press cupping tool device, it be set in place in the concavo-convex mould of top and below the blanking die with blank holder and blank holder push rod between; It is characterized in that: described male and female mold has the patrix depression bar, blanking die is provided with the hole in the position of corresponding patrix depression bar, hole and release adjusting rod cunning are joined, spring housing is installed in the mold center of blanking die bottom, the flanging spring places the spring housing center, backing plate is installed in flanging spring bottom, and air spring supporting plate and air spring are fixed in pressing equipment lower table center.
Described punching press cupping tool device, it is characterized in that: the air spring supporting plate is buckled in above the air spring stick harness.
Described punching press cupping tool device is characterized in that: air spring load is greater than more than 1.3 times of flanging spring load.
The beneficial effects of the utility model are, improve the wall unevenness of pull and stretch part product, optimize deep-drawing technique, and have characteristics such as simple in structure, practical, easy to operate.
Description of drawings
Fig. 1 is a cross-sectional view of the present utility model;
Among the figure, 1 punch-die, 2 patrix depression bars, 3 blank holders, 4 blanking dies, 5 blank holder push rods, 6 release adjusting rods, 7 spring housings, 8 flanging springs, 9 backing plates, 10 air spring supporting plates, 11 air springs.
The specific embodiment
As shown in Figure 1, the utility model provides a kind of punching press cupping tool device, it be set in place in the concavo-convex mould 1 of top and below the blanking die 4 with blank holder 3 and blank holder push rod 5 between.Described concavo-convex mould 1 has patrix depression bar 2 (being generally four), blanking die 4 is provided with the hole in the position of corresponding patrix depression bar 2, hole and 6 sliding joining of release adjusting rod, spring housing 7 is installed in the mold center of blanking die 4 bottoms, flanging spring 8 places spring housing 7 centers, backing plate 9 is installed in flanging spring 8 bottoms, and air spring supporting plate 11 and air spring 10 are fixed in pressing equipment lower table center, but the height free adjustment.Described air spring supporting plate 11 is buckled in above air spring 10 stick harnesses.
Flanging spring 8 can be changed the rectangle spring of reasonable load according to the pressure-pad-force of different product, the release adjusting rod can be adjusted its length according to wrinkling critical point, air spring 10 also can be according to the enterprise practical situation, adopt spring, rubber, the gas-pressure adjustable cushion pad, nitrogen spring etc., principle is greater than more than 1.3 times of flanging spring load.
During work, along with forcing press is descending, finish blanking earlier, forcing press continues descending, the blanking sheet the pressure of punch-die 1 and blank holder 3 by the active force of flanging spring 8 in the middle of the beginning pull and stretch, along with forcing press continues descending, plate is clamp-oned die by punch, finish material deformation, wrinkling process, this moment, patrix depression bar 2 was also by pushing down release adjusting rod 6, reach the purpose of flanging spring 8 unloadings, therefore the descending transition pull and stretch that becomes no pressure-pad-force that just develops has solved the unfavorable factor that common cupping tool pressure-pad-force strengthens along with the increase of drawing depth after the forcing press.
Being preferred embodiment of the present utility model only in sum, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should be technology category of the present utility model.
