Abstract
The utility model discloses a forging and pressing die for a spline hub in a horizontal forging machine, which comprises a convex die and a concave die; the left side of the concave die is provided with an inner round surface; an inwardly recessed step is disposed corresponding to the left end of the convex die on the inner round surface of the concave die; and an arc chamfer is disposed at connection transition position of the inner round surface and the step. The left side of the concave die is provided with the step, so the forging and pressing die is easily separated after the spline hub is forged. By such improvement, production efficiency is improved, production quantity is increased and enterprise benefit is improved.
Description
Technical field
The utility model relates to horizontal forging and upsetting machine and uses mould, especially relates to a kind of splined hub forge die.
Background technology
Horizontal forging and upsetting machine refers to the metal forming machinery of the long bar of horizontal direction upsetting and the end of pipe material.Horizontal forging and upsetting machine comprises 3 groups of motions: 1. punch (drift): reciprocating in the horizontal direction, 4～6 impressions generally can be set, be used to gather, the builder of upsetting operation such as heading, punching, flange, also be main force application mechanism.2. movable matrix: can be upper and lower to or laterally folding, in order to the long bar of clamping, and bear the end upset force.3. shut-off mechanism: in order to forging is separated from long bar.Horizontal forging and upsetting machine adopts the slider-crank mechanism transmission usually, because processing work is big, upset force and clamping force are big, and machinery requirement has enough rigidity, to guarantee the precision of flat forging.According to the die joint position of die, horizontal forging and upsetting machine can be divided into two types of vertical minute mould and horizontal partings.Horizontal forging and upsetting machine commonly used is the vertical mould that divides.The horizontal forging and upsetting machine operating condition of horizontal parting is better, easily be automated, but structure is complicated.
As shown in Figure 5, splined hub 3 left end cylindricals are the face of cylinder.Because it is bad with the external diameter size identical property of central siphon that present splined hub 3 is made, the clamping die is inoperative under the little situation of central siphon external diameter, causes splined hub 3 to be bonded on the punch, is bonded on the punch pretty troublesomely, even scraps splined hub and punch.
The utility model content
The purpose of the utility model is to provide a kind of splined hub forge die of when making splined hub, being convenient to throw off.
The technical scheme of the utility model is:
Horizontal forging and upsetting machine splined hub forge die comprises punch and die, and said die left side is provided with inner headed face, is provided with the step that concaves with punch left end corresponding position on the inner headed face of said die.
Said inner headed face is provided with circular arc chamfering with the transition position that is connected of step.
The utility model is provided with the step that concaves in the die left side, forges the back that finishes in splined hub and throws off easily.Improvement through such has improved production efficiency, has increased output, has improved the benefit of enterprise.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the partial enlarged drawing of Fig. 2;
Fig. 4 is the shape sketch map of the splined hub of employing the utility model processing;
Fig. 5 is the shape sketch map of existing splined hub.
The specific embodiment
Like Fig. 1, shown in 2, the utility model comprises die 1 and punch 2, and the shape of die 1 and punch 2 is set according to the shape of splined hub to be processed 3.Die 1 is installed on the pedestal 5.Die 1 left end is provided with inner headed face.
As shown in Figure 3, for the smooth demoulding, between the φ 1 of die 1 and φ 2, added step 4, φ 1 is connected transition position with φ 2 circular arc chamfering is set, and through after such improvement, even clamp recessed inoperatively, forging is the demoulding smoothly also.As shown in Figure 4, splined hub 3 left ends after the processing have a step surface.Simultaneously, through repetition test, the wall thickness between φ 2 and the φ 3 should be consistent with the wall thickness of central siphon basically, the too small not easy-formation of the wall thickness between φ 2 and the φ 3.
Below be the superiority such as the following table of producing contrast in production splined hub on the horizontal forging and upsetting machine with in loose tooling forging:
Is 8 times of production efficiency in loose tooling forging through last table contrast splined hub in production efficiency on the horizontal forging and upsetting machine; Can push up the production quantity of whole teams and groups (8 people) in loose tooling forging in average production quantity for each person every day on the horizontal forging and upsetting machine; And production stability is very high on horizontal forging and upsetting machine, and owing to the bad control of the heat amount of rising, a mould needs frequent wet water-cooled but on loose tool, and the size maximum of the forging of beating before the firm forging of beating in cooling back and the water that will wet differs several millimeters.
From the economic angle analysis: under production efficiency and the guaranteed prerequisite of quality, produce than produce and to economize out many extraneous expenses for company,, therefore can reduce hundreds thousand of wage expenditures owing to reduced number in loose tooling forging at horizontal forging and upsetting machine.
The material savings situation:
In production splined hub on the horizontal forging and upsetting machine than production economical with materials situation on loose tool: average each forging material-saving 0.03kg, 18 tons of 600,000 forging material-savings, can be saved 106200 yuan by average 5900 yuan per ton.
Mould is saved situation:
4000 yuan of horizontal forging and upsetting machine one molds can be produced 12000 of forging; 600 forging of 2000 yuan of each production of loose tool one mold, average every cover die prodigiosin is overhauled 6 times, can produce 3600 of forging altogether.600,000 forging productions on horizontal forging and upsetting machine need 200000 yuan of costs, and production needs 333333 yuan of costs on loose tool, can save 130000 yuan.
