Abstract
The utility model discloses a transmission shaft middle flange forging die which comprises an upper die block and a lower die block. A die mold cavity is arranged in the lower die block. A boss is arranged on the top of the lower die block. A groove matched with the boss in a clamped and sleeved mode is arranged at the bottom of the upper die block. A forging head which faces downward and extends into the die mold cavity is arranged at the bottom of the groove. The lower die block and the upper die block are matched through the boss and the groove in a top-and-bottom mode. Through adoption of the technical scheme, the die mold cavity is fully arranged in the lower die block, and the lower die block is matched with the upper die block through the boss and the groove in a top-and-bottom mode, so deviation of forge pieces in the forging process can be avoided. Due to the fact that the die mold cavity is fully arranged in the lower die block, forging flash does not need forging, raw materials are saved, cost of machining of the upper die block is saved, and naturally, the machining cost of the whole die is reduced.
Description
Technical field
The utility model belongs to the auto industry technical field, relates in particular to a kind of power transmission shaft intermediate bead forging mold.
Background technology
At present, the mold cavity structure that the power transmission shaft intermediate bead is traditional is, the upper and lower module of mould has the distribution of die cavity, the forging of under this mold cavity, producing, can produce overlap, and the forging defect such as offsetting appears easily, upper and lower module all distributes, and the center of module is entirely on the center up and down when just needing Mould Machining for die cavity, this has just increased the difficulty of Mould Machining, corresponding die cost, the mould production cycle all needs to increase accordingly, has only just significantly improved production cost in one of mould production.In the subsequent production process, mould centering problem can be wasted man hour of labour, has reduced labor productivity, has increased labour cost.In a word, under this mould, produce middle lug forging, not only increased production cost and also reduced production efficiency, do not meet with the theory of saving energy and reduce the cost.The structure of this mold cavity has following defective and deficiency:
1, mold cavity is having distribution in the module up and down, produces easily offsetting and waits forging defect;
2, there is the forging overlap, the waste raw material, and need the side cut operation, naturally increased production cost;
3, mold cavity is distributed in up and down module, and the subsequent treatment that is produced by mould upper and lower mould centering has increased the Mould Machining cost;
4, because the generation of overlap is arranged, the utilization rate of material is on the low side, the waste raw material, and the forging cost is high.
The utility model content
The utility model provides a kind of good stability, forges the low power transmission shaft intermediate bead forging mold of product non-trimming, processing cost out in order to solve weak point of the prior art.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: power transmission shaft intermediate bead forging mold, comprise upper module and lower module, be provided with mold cavity in the described lower module, the lower module top is provided with boss, the upper module bottom is provided with the groove that cooperates with the boss cutting ferrule, and bottom portion of groove is towards having the forging and pressing head that extend in the mold cavity, and lower module and upper module cooperate up and down by boss and groove.
Described lower module bottom upwards is provided with the vertical slotted hole that is communicated with mold cavity, vertical slotted hole is made of the thinner section on top and the wider section of bottom, be provided with circular push rod in the vertical slotted hole, circular push rod is made of with the head that is positioned at vertical slotted hole wider section the bar section that extend into vertical slotted hole thinner section.
The sidepiece of described upper module and lower module is equipped with hole for hoist.
Adopt technique scheme, by mold cavity all be arranged in the lower module and lower module and upper module by the cooperation of boss and groove, can prevent like this offsetting of forging in forging process.Because mold cavity all is arranged in the lower module, so just do not have the problem of forging overlap, thereby save material, and mold cavity is arranged in the lower module, saved the cost of processing upper module, naturally reduced the processing cost of whole mould.Circular push rod is used for the forging in the mold cavity is ejected.Hole for hoist is used for installing and fixing upper module and lower module.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, power transmission shaft intermediate bead forging mold of the present utility model, comprise upper module 1 and lower module 2, be provided with mold cavity 3 in the lower module 2, lower module 2 tops are provided with boss 4, upper module 1 bottom is provided with the groove 5 that cooperates with boss 4 cutting ferrules, groove 5 bottoms are towards having the forging and pressing that extend in the mold cavity 39, forging and pressing 9 are structure as a whole with upper module, form the shape of power transmission shaft intermediate bead between forging and pressing 9 lower surface and the mold cavity 3, lower module 2 and upper module 1 cooperate up and down by boss 4 and groove 5.
By mold cavity 3 all be arranged in the lower module 2 and lower module 2 and upper module 1 by the up and down cooperation of boss 4 and groove 5, can prevent like this offsetting of forging in forging process.Because mold cavity 3 all is arranged in the lower module 2, so just do not have the problem of forging overlap, thereby save material, and mold cavity 3 is arranged in the lower module 2, saved the cost of processing upper module 1, naturally reduced the processing cost of whole mould.Circular push rod 7 is used for the forging in the mold cavity 3 is ejected.Hole for hoist 8 is used for installing and fixing upper module 1 and lower module 2.
Adopt the technical solution of the utility model, aspect consumption reduction: the stock utilization of bead is on average about 90% in the middle of under the former FMT, the utility model adopts the non-trimming FMT, can bring up to about 98% through the test material utilization rate, average energy improves 8% percentage point, presses every average weight 5Kg of middle lug forging and calculates 200,000 of intermediate bead annual productions, steel per ton are by 3800 yuan/tons, and raw material can be saved 5Kg * 8% * 200,000 * 3800 yuan/tons=30.4 ten thousand yuan every year.Aspect energy-conservation: calculate from the energy consumption of heating blank, adopt Frequency Induction Heating, through test per kilogram blank heating energy consumption about 0.5Kw.h(0.5 degree), but every saves energy 5 * 8% * 0.5=0.16 degree, but every year power cost saving: 0.4 spends * 20 ten thousand * 0.65 yuan=5.2 ten thousand yuan.
