Abstract
The invention discloses a drawing die with an elastic pressing plate so as to solve the problem that the edge pressing force of an existing elastic pressing plate is small. The drawing die with the elastic pressing plate comprises a female die; a mold cavity is formed in the female die; a male die capable of moving vertically is arranged over the female die; the upper end of the male die is installed on a male die fixing plate; the lower portion of the male die fixing plate is provided with the elastic pressing plate used for pressing edges. A vertical positioning hole is formed in the elastic pressing plate. A vertical positioning bolt is arranged on the upper portion of the male die. When the male die moves downwards, the positioning bolt can penetrate the positioning hole, and the elastic pressing plate is locked and positioned through a nut.
Description
Technical field
The present invention relates to a kind of Drawing Die with spring bearer plate.
Background technology
Drawing is widely used in the production of the product of the various industrial departments such as automobile, electronics, commodity, instrument, and drawing not only can process rotating body parts, also can process and close shape part and other complex-shaped thin-walled parts.Drawing utilizes Drawing Die under the effect of forcing press, plate blank or hollow object made the processing method of open hollow part.The punch that the basic structure of Drawing Die comprises die, blank location-plate that die top is arranged and coordinates stamping strip shaping with die, in addition in order to when stretching, keep the rim charge level of periphery, also be provided with flange fixing installation, existing flange fixing installation adopts spring bearer plate usually, it relies on spring to produce elastic force, the deficiency existed is: due to the limited space between punch and pressing plate, therefore thicker spring cannot be installed, therefore to be applied to the elastic compression power of pressing plate less for spring, is only suitable for the drawing part that pressure-pad-force is less.
Summary of the invention
The invention is intended to provide a kind of Drawing Die with spring bearer plate, with the problem that the pressure-pad-force solving existing spring bearer plate is less.
The Drawing Die of the band spring bearer plate in this programme, comprise die, die is provided with die cavity, being provided with directly over die can the punch of vertical motion, and punch upper end is arranged on punch retainer, and the bottom of punch retainer is provided with the spring bearer plate for flanging, described spring bearer plate has vertical locating hole, be provided with vertical bolt on die top, when punch is descending, bolt can through locating hole and by nut by spring bearer plate locking positioning.
The invention has the advantages that: during working flat plate blank, first blank is placed on the top of die, then punch retainer drives punch descending, drives spring bearer plate descending simultaneously, spring bearer plate pushes down blank top after descending putting in place, simultaneously, bolt passes the locating hole on spring bearer plate, in order to lock spring bearer plate, by nut, spring bearer plate is locked, guarantee positioning stablity, punch continuation is descending carries out drawing and forming to blank, until mold the opening member of required form.This programme can guarantee that spring bearer plate has larger pressure-pad-force.
Further, punch retainer has vertical installing hole, installing hole inner sliding sleeve is provided with alignment pin, and lower end and the spring bearer plate of alignment pin are fixed, between spring bearer plate and punch retainer, be provided with spring.Alignment pin not only plays the effect connecting spring bearer plate, and play the guiding role to the motion of spring bearer plate, and spring provides the elastic force of spring bearer plate.
Further, being provided with in the below of die can the ejector beam of vertical motion, and the upper end of ejector beam is fixed with die pad, and die pad can extend in die cavity.Drive die pad that the opening member of forming is ejected die cavity by ejector beam, because the active area of die pad and opening member is large, makes opening member uniform force, can not cause it when going out part and scrape damage etc.
Further, have pilot hole at the middle part of spring bearer plate, by described pilot hole when punch is descending.The pilot hole of extra setting, when punch downward movement, has the effect of guiding to it, make its die-closed position more accurate, precision is higher.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: die shank 1, upper bolster 2, punch retainer 3, spring 4, spring bearer plate 5, location-plate 6, die 7, die shoe 8, alignment pin 9, punch 10, locating hole 11, bolt 12.
Embodiment is substantially as shown in Figure 1: the Drawing Die of the present embodiment band spring bearer plate, punch is fixed on punch retainer, punch retainer is fixed on upper bolster, and upper bolster top is provided with die shank, die shank, upper bolster, punch retainer and punch can under the drive of power vertical motion.
Punch retainer with upper bolster all have the vertical installing hole be communicated with, installing hole inner sliding sleeve is provided with alignment pin, lower end and the spring bearer plate of alignment pin are fixed, spring is provided with between spring bearer plate and punch retainer, the upper end of spring is fixed on the bottom of punch retainer, and the lower end of spring is fixed on the top of spring bearer plate.Pilot hole is had, by described pilot hole when punch is descending at the middle part of spring bearer plate.
The die of the present embodiment is positioned at immediately below punch, and die is provided with die cavity, and die cavity is stairstepping, and die is fixed on die shoe, and die is fixedly connected with by screw with die shoe.Being provided with in the below of die can the ejector beam of vertical motion, and the upper end of ejector beam is fixed with die pad, and die pad can extend in die cavity.Die top is provided with location-plate.
The lower surface of the spring bearer plate of the present embodiment has boss, and spring bearer plate has vertical locating hole, is provided with vertical bolt on die top, and when punch is descending, bolt can through locating hole and by nut by spring bearer plate locking positioning.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
