Abstract
The utility model belongs to the mechanical die field, and specifically relates to an easily-detachable lower die fixing structure for cold forging dies. The easily-detachable lower die fixing structure comprises a lower die plate, below which a first lower backing plate, a second lower backing plate and a lower die holder are arranged in order. The lower die plate and the first lower backing plate are coupled and fixed via a lower die plate screw and a changeable positioning pin. The second lower backing plate is fixed on the lower die holder via a fastening screw and a changeable positioning pin. The lower die plate and one side of the first lower backing plate are coupled and fixed with the lower die holder via a lower-die-plate press block and a press block bolt. The surface of the other side of the lower die holder is provided with an inverted T-shaped groove in a milling manner. A T-shaped block with a thread hole is arranged in the groove. A T-shaped block bolt passes through through holes in the lower die plate, the first lower backing plate and the second lower backing plate so as to be screwed up and fixed with the T-shaped block. Since the easily-detachable lower die fixing structure of the utility model uses significantly less screws compared with a conventional structure and adopts the T-shaped block and an L press block mechanism, a lot of man hours are saved and the labor productivity is increased when lower die components are detached.
Description
[technical field]
The utility model belongs to the machine die field, more particularly, relates to a kind of cold punching forging die counterdie fixed structure that is easy to dismantle.
[background technology]
In commercial production; Sheet Metal Forming Technology has the economical with materials and the energy owing to compare traditional mechanical processing; Efficient is high, can make these advantages of product that machining is beyond one's reach to not high the reaching through various moulds application of operator's specification requirement, thereby its purposes more and more widely.Punch press presses to material, makes its plastic deformation, and obtains desired shape and precision, therefore must cooperate one group of mould (dividing counterdie and counterdie), and material is placed therebetween, is exerted pressure by machine, makes its distortion.Counterdie is the Lower Half of whole secondary punch die, promptly is installed on the punch die part on the press bench face.In actual production,, need dismounting lower bolster, lower bolster 1, lower bolster 2, die shoe usually usually because the fracture or the wearing and tearing (like the buoyance lift pin) of certain accessory of bigger cold punching forging die counterdie need the whole counterdie of dismounting.Also have between above-mentioned each plate that alignment pin, die edge are fast, buoyance lift pin, discharging spring and a large amount of screws.Cold punching forging die counterdie for bigger often removes and need spend time a couple of days, has had a strong impact on the production efficiency of enterprise.
[utility model content]
The utility model technical problem to be solved is to provide a kind of quick detaching structure that can in a few minutes, the punching press counterdie be disassembled, and saves man-hour, improves the production efficiency of enterprise.
The technical scheme of the utility model is: the cold punching forging die counterdie fixed structure that is easy to dismantle; Comprise lower bolster; Said lower bolster below is provided with first lower bolster, second lower bolster and die shoe successively; Be connected and fixed through lower bolster screw and interchangeable alignment pin between the wherein said lower bolster and first lower bolster, said second lower bolster is fixed on the die shoe through trip bolt and interchangeable alignment pin; Said lower bolster and first lower bolster, one side are connected and fixed through lower bolster briquetting and lower bolster briquetting and briquetting bolt and said die shoe; Said die shoe opposite side surface is milled with inverted T-slot, is provided with one in the said groove and is threaded the T shape piece in hole, and tighten fixing with through hole and said T shape piece that T shape piece bolt passes on said lower bolster, first lower bolster and second lower bolster.
As the further improvement of such scheme, the said said lower bolster of lower bolster briquetting aspect ratio and first lower bolster, the few 1mm of the second lower bolster thickness sum.
The advantage of the utility model is: because the screw number that the cold punching forging die counterdie of the utility model uses greatly reduces than traditional structure and uses T shape piece and L forming machanism; Saved and be used for the time of knockout screw in a large number and selectively dismantle different module; Significantly improve the speed of decomposing the punching press counterdie, can in a few minutes, cold punching forging die counterdie have been disassembled, solved the difficult technical problem of cold punching forging die counterdie dismounting effectively; Accelerated the installation rate of cold punching forging die counterdie simultaneously; Reduce the punching press counterdie recruitment quantity has been installed, reduced construction cost, improved labor productivity.
[description of drawings]
Combine embodiment that the utility model is done further to describe with reference to the accompanying drawings.
Fig. 1 is the utility model cold punching forging die counterdie fixed structure sketch map,
Among the figure: 1, lower bolster; 2, interchangeable alignment pin; 3, lower bolster briquetting; 4, briquetting screw; 5, screw; 6, interchangeable alignment pin; 7, die shoe; 8, T shape piece; 9, second lower bolster; 10, first lower bolster; 11, T shape piece bolt.
[specific embodiment]
Further specify the utility model through embodiment below, and the utility model is not restricted to said embodiment, all similar with the utility model structure, and only be that size, position are adjusted or change person to some extent, then all belong to the protection category of the utility model.
Participate in Fig. 1; The cold punching forging die fixed structure that is easy to dismantle; Comprise lower bolster 1; Lower bolster 1 below is provided with first lower bolster 10, second lower bolster 9 and die shoe 7 successively, wherein is connected and fixed through lower bolster screw 2 and interchangeable alignment pin 1 between the lower bolster 1 and first lower bolster 10, and second lower bolster 9 is fixed on the die shoe 7 through screw 5 and interchangeable alignment pin 6; Lower bolster 1 and first lower bolster, 10 1 sides are connected and fixed with die shoe 7 through lower bolster briquetting 3 and briquetting screw 4; Die shoe 7 opposite side surfaces are milled with inverted T-slot, be provided with in the groove one be threaded the hole T shape piece 8, and pass through hole and T shape piece 10 on lower bolster 1, first lower bolster 10 and second lower bolster 9 with T shape piece bolt 11 and tighten fixingly, reach the purpose of locking.
For lower bolster 1 and first lower bolster, 10 1 sides are compressed through lower bolster briquetting 3 and second lower bolster, 9 surfaces, the said lower bolster 1 of lower bolster briquetting 3 aspect ratios and first lower bolster 10, the few 1mm of second lower bolster, 9 thickness sums.When the dismounting counterdie,, just can retract lower bolster 1 as long as back out T shape piece bolt 11 and briquetting bolt 4.
Although illustrated and described the embodiment of the utility model; For those of ordinary skill in the art; Be appreciated that under the situation of principle that does not break away from the utility model and spirit and can carry out multiple variation, modification, replacement and modification to these embodiment, the scope of the utility model is limited accompanying claims and equivalent thereof.
