Abstract
The utility model discloses a side cut mould device on compound die that punches a hole, include last pressure head, double -end connecting screw rod, press the headrest board, go up stool and fastening bolt, press the headrest board to pass through fastening bolt fixed mounting on last stool, go up the pressure head and pass through double -end connecting screw rod and press headrest board fixed connection, and press the lower terminal surface of headrest board and the up end of last pressure head and closely laminate. The utility model discloses simple structure adopts double -end connecting screw rod will go up the pressure head fastening on pressing the headrest board, can make things convenient for during the pressure head change the outfit on and load and unload fast, and workman intensity of labour has been reduced to apparent landing, has improved the operating efficiency that changes the outfit.
Description
Technical field
The utility model relates to technical field of mold, more particularly, particularly relates to a kind of for the trimming of working plate-like gear die forging stock part, the upper mould device of punching composite die.
Background technology
Usually, need after blank die forging to do trimming and punching process, to reduce mechanical cold working process.In the upper mould device of the existing trimming for processing mould forging stock part, punching composite die, the seaming chuck playing trimming and punching effect wants prior bolted to be arranged on pressure head backing plate and to form sub-assembly, again this sub-assembly bolt and upper baffle plate are fastenedly connected, correct through adjustment, the processing process of trimming, punching can be carried out die forging blank.If the unsuitable punching of the draw ratio of forging stock part, then only do trimming process.
Seaming chuck is undertaken manufacturing and designing by the cylindrical of forging stock and hole size requirement, the seaming chuck of often kind of forging stock configure dedicated, when the forging stock of rotation production different cultivars need replace with pressure head, seaming chuck sub-assembly to be unloaded from upper baffle plate, change the outfit need seaming chuck after, again sub-assembly is reinstalled upper baffle plate, adjustment uses.
Handling sub-assembly needs multi-person synergy to carry out, owing to adopting bolted, there is accumulation alternate position spike in the through hole of upper baffle plate and the screw of pressure head backing plate, add the difference gap of bolt and through hole, during installation, need two people to lift assembly, a people commands and aims at screw and be screwed into bolt, this process time is long, and the personnel that lift comparatively require great effort; When unloading, need a people to unload bolt, two people lift, work compound, to ensure the safety of the person, unit.Such handling mode, effort, consuming time, a tax on one's mind, affect job scheduling, especially adapt to the tractor gear market demand and criticize volume feature little, wide in variety, every batch of output is little, and frequent rotation kind more feels very inconvenient, must operating type be improved, improve operating efficiency.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provides a kind of edge-cutting and hole-punching compound die upper mould device easy to loading and unloading, improves handling operation efficiency.
For achieving the above object, the technical solution adopted in the utility model is: a kind of edge-cutting and hole-punching compound die upper mould device, comprise seaming chuck, double end connecting screw rod, pressure head backing plate, upper baffle plate and fastening bolt, described pressure head backing plate is fixedly mounted on upper baffle plate by fastening bolt, described seaming chuck is fixedly connected with pressure head backing plate by double end connecting screw rod, and the lower surface of pressure head backing plate and the upper surface of seaming chuck fit tightly.
The utility model structure is simple, adopts double end connecting screw rod to be fastened on by seaming chuck on pressure head backing plate, can load and unload quickly and easily, significantly reducing labor strength, improve the operating efficiency that changes the outfit when installing pressure head.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-seaming chuck; 2-double end connecting screw rod; 3-pressure head backing plate; The upper baffle plate of 4-; 5-fastening bolt.
Detailed description of the invention
Below in conjunction with the embodiment in accompanying drawing, the utility model is described in further detail, but do not form any restriction of the present utility model.
As shown in Figure 1, a kind of edge-cutting and hole-punching compound die upper mould device that the utility model provides, comprise seaming chuck 1, double end connecting screw rod 2, pressure head backing plate 3, upper baffle plate 4 and fastening bolt 5, described pressure head backing plate 3 is fixedly mounted on upper baffle plate 4 by fastening bolt 5, described seaming chuck 1 is fixedly connected with pressure head backing plate 3 by double end connecting screw rod 2, and the upper surface of the lower surface of pressure head backing plate 3 and seaming chuck 1 fits tightly.
The utility model is easy to loading and unloading, during assembling, one end of double end connecting screw rod 2 is screwed in the center screw of seaming chuck 1, the shoulder of double end connecting screw rod 2 is made to be close to the end face of seaming chuck 1, composition seaming chuck assembly, fastening in the center screw then other end of double end connecting screw rod 2 being screwed into pressure head backing plate 3, so that seaming chuck 1 is packed on pressure head backing plate 3, complete the installation of upper mould device, do can produce after centering adjusts with lower mold apparatus; When pressure head 1 will be installed, seaming chuck component integration need be unloaded from pressure head backing plate 3, the seaming chuck changing needs again on double end connecting screw rod 2 forms new seaming chuck assembly, then new seaming chuck assembly is loaded pressure head backing plate 3, the lower surface of the upper surface of seaming chuck 1 and pressure head backing plate 3 is fitted tightly, to ensure the result of use of seaming chuck 1 and to reduce the rate of wear that end face located by pressure head backing plate 3, improve result of use and the service life of upper mould device on the whole.
Because pressure head backing plate 3 is fixedly mounted on upper baffle plate 4, only load and unload when mainteinance repair, play upper baffle plate 4 centering precision of protection and the effect in service life better, also mitigate the weight of seaming chuck assembly simultaneously, decrease the time of stubborn bolt significantly.Need when installing pressure head in the past that two people lift, a people twists bolt, handling once more than 30 minutes consuming time, now only need two people's operations, can complete in 10 minutes and change the outfit, reduce labor strength, improve the operating efficiency that changes the outfit, save labour, shorten man hour of labour, achieve good economic benefit.
