Detailed description of the invention
Core of the present utility model is to provide a kind of trimming die producing middle waste material, to simplify the discharging operations of middle waste material, improves stock utilization simultaneously, reduces the frock cost of parts.
In order to make those skilled in the art understand the technical solution of the utility model better, below in conjunction with accompanying drawing, the utility model is further detailed.
As Figure 1-4, the utility model embodiment provides a kind of trimming die producing middle waste material, this trimming die comprises upper bolster 11, edge iron block 12, material pressing core 13, die shoe 21, deburring punch 22 and shedding mechanism, edge iron block 12 and material pressing core 13 are all installed on upper bolster 11, deburring punch 22 and shedding mechanism are all installed on die shoe 21, and deburring punch 22 matches with edge iron block 12 and can realize deburring and operate.The middle part of deburring punch 22 has the installing space of accommodating shedding mechanism, shedding mechanism comprises discharging core 23 and elastomeric element 24, discharging core 23 can move along the upper bolster direction of motion relative to deburring punch 22, elastomeric element 24 is arranged between discharging core 23 and die shoe 21, it can be spring, discharging core 23 has waste material support portion, this waste material support portion is for supporting the middle waste material of parts.
During above-mentioned trimming die work, first parts to be processed are positioned on discharging core 23, make middle waste material be supported on the waste material support portion of discharging core 23, when upper bolster 11 is descending, upper bolster 11 contacts parts gradually, after discharging core 23 is under pressure by force transmission to elastomeric element 24, elastomeric element 24 is out of shape, and after parts contact with deburring punch 22, material pressing core 13 carries out binder operation, edge iron block 12 and the effect of deburring punch 22 phase, can carry out deburring operation.After deburring completes, middle waste material is separated with the finishing section of parts, middle waste material is still supported by discharging core 23, along with upper bolster 11 is up, the pressure that discharging core 23 is subject to is cancelled, and elastomeric element 24 recovers deformation, and then drives discharging core 23 up, middle waste material is made to protrude from the deburring finishing section of parts, so that operating personnel carry out feeding operation.
Known by foregoing description, the trimming die that the utility model embodiment provides supports middle waste material by discharging core 23, and making middle waste material can protrude from the deburring finishing section of parts by elastomeric element 24, middle waste material can easily take out by operating personnel; Meanwhile, without the need to cutting middle waste material, make the structure that middle waste material keeps complete, so that secondary utilizes, and without the need to additionally arranging cutting part in trimming die.Obviously, compared to the content introduced in background technology, the trimming die that the utility model embodiment provides can either simplify the discharging operations of middle waste material, can improve stock utilization simultaneously, reduces the frock cost of parts.
Further, above-mentioned shedding mechanism also comprises the lifting portion be arranged in the middle part of discharging core 23, and this lifting portion comprises the jacking part with waste material jacking face and the power part 25 driving this jacking part, and this power part can be preferably lifting jack.Jacking part has two positions under the effect of power part 25, wherein a position, and middle waste material is supported by discharging core 23, and jacking part then can not contact with middle waste material, also can contact with middle waste material; In another position, jacking part protrudes from the waste material support portion on discharging core 23, and middle waste material is only supported by jacking part.The height of waste material in the middle of lifting portion in this structure can increase further after deburring terminates, so that operating personnel carry out feeding operation.
During concrete enforcement, the structure of above-mentioned jacking part can be arranged arbitrarily, in order to alleviate the weight of trimming die, the jacking part that the utility model embodiment provides comprises jacking frame 26 and multiple jacking block 27, jacking frame 26 is connected with power part 25, each jacking block 27 is fixed on the edge of jacking frame 26, and waste material jacking face is arranged on jacking block 27.Power part 25 drives jacking block 27 to rise or decline by jacking frame 26, with waste material in the middle of this jack-up.
Further in technical scheme, above-mentioned jacking block 27 can be rigid structure, and also can be elastic component, the utility model is preferably elastic component, is scratched by jacking block 27 to avoid middle waste material.
In aforementioned each technical scheme, the lower surface of upper bolster 11 can Direct driver discharging core 23 descending, but under this kind of mode, when upper bolster 11 is up and after being separated with parts, discharging core 23 is subject to the active force from elastomeric element 24 in the short period of time, cause the motion state change that discharging core 23 occurs rapidly, make discharging core 23 and the motion conditions of instability appears in the parts that are connected with discharging core 23.Accordingly, the utility model embodiment arranges and plays ejector pin 14 on upper bolster 11, and one end of this bullet ejector pin 14 is free end, this free end has the pressure portion that can abut against with discharging core 23.Play ejector pin 14 to slide relative to upper bolster 11, himself has flexible member, upper bolster 11 applies pressure by playing ejector pin 14 to discharging core 23, when upper bolster 11 is up, even if upper bolster 11 is separated with parts, play ejector pin 14 still to contact with discharging core 23 within a period of time, and then cushioning effect is played to the motion of discharging core 23, to alleviate foregoing problems.
In order to control the movement travel of discharging core 23, locating part 28 can be set firmly on die shoe 21, discharging core 23 has the spacing hole extended along the upper bolster direction of motion, locating part 28 is snug fit in spacing hole, locating part 28 have the first limiting section and the second limiting section, first limiting section and the second limiting section lay respectively at the both sides of spacing hole, and both can abut against with two apparent surfaces of discharging core 23 respectively.After so arranging, when discharging core 23 is up and descending, when its surface contacts with the first limiting section or the second limiting section, namely discharging core 23 cannot move relative to die shoe 21, controls the movement travel of discharging core 23 with this.
Preferably, die shoe 21 also can fix guide pillar 29, discharging core 23 has the pilot hole extended along the upper bolster direction of motion, guide pillar 29 is snug fit in this pilot hole.By coordinating of guide pillar 29 and pilot hole, the motion that namely can be discharging core 23 provides guide effect, makes the motion of discharging core 23 more stable.Based on this, in order to alleviate the wearing and tearing between guide pillar 29 and discharging core 23, also can arrange sliding sleeve 30 further, guide pillar 29 is slidably matched by sliding sleeve 30 and pilot hole, by optimizing the material of sliding sleeve 30, the wearing and tearing of guide pillar 29 and discharging core 23 can be made all to decrease.
In view of discharging core 23 weight of trimming die is comparatively large, for the ease of transport and assembling, can adopt the above-mentioned discharging core 23 of suspender handling, therefore can set firmly hanging part 31 on discharging core 23, this plays lifting screw thread hanging part 31 having and can be connected with suspender.After being threaded with a hanging part 31 by suspender, lifting appliance moving discharging core 23 can be adopted.
Mode above only by illustrating describes some one exemplary embodiment of the present utility model, undoubtedly, for those of ordinary skill in the art, when not departing from spirit and scope of the present utility model, can revise described embodiment by various different mode.Therefore, above-mentioned accompanying drawing is illustrative with being described in essence, should not be construed as the restriction to the utility model claims.
