Abstract
The invention discloses a shaping mechanism for automobile rear sub-frame lower plate negative angle double edges. The shaping mechanism for the automobile rear sub-frame lower plate negative angle double edges comprises a lower mould base plate, a lower concave mould, an upper mould base plate and an upper concave mould. The upper mould base plate is installed on a sliding block of an oil pressure machine and driven to lift and move by the sliding block. An upper heel block is arranged under the upper mould base plate and the upper concave mould is arranged under the upper heel block. The lower concave mould is arranged on the lower mould base plate and a guiding column is arranged in the middle of the lower concave mould. A convex mould movable core is arranged on the guiding column of the lower concave mould and an elastic component is arranged under the convex mould movable core. The automobile rear sub-frame lower plate negative angle double edges are shaped by the mechanism which is provided with a frontal shaping mould, so that the effect is ideal, and the mould is simple in structure, the cost is low, the service life of the mould is long, the operation is easier and the stability is better.
Description
Technical field
The present invention relates to technical field of mold, particularly relate to a kind of mould of carrying out shaping bilateral to automobile rear sub-frame lower plate negative angle.
Background technology
Subframe can regard the skeleton of tandem axle as, it it is the ingredient of tandem axle, subframe incomplete vehicle frame, simply support tandem axle, the support hung, make vehicle bridge, hang and be connected with " positive vehicle frame " again by it, it is referred to as " subframe " traditionally, the effect of subframe is to intercept vibration and noise, reduce it and be directly entered compartment, so mostly occurring on luxurious car and offroad vehicle, some automobile also loads onto subframe for engine, monocoque body conventional without subframe, its suspension is directly to be connected with vehicle body steel plate, therefore the suspension rocker arm body of tandem axle is all loose mail, not assembly, after subframe is born, front and rear suspension can first be assembled on subframe, constitute an axle assembly, the most again this assembly is together installed on vehicle body,
Existing automobile rear sub-frame lower plate negative angle needs shaping, and typically in side, shaping completes, but side shaping mold has structure complicated, and high cost, the shortcomings such as die life is short, therefore, the problem solving this class is particularly important.
Summary of the invention
For the deficiencies in the prior art, the present invention provides a kind of front shaping mould mechanism to carry out front shaping to automobile rear sub-frame lower plate negative angle is bilateral, the problem bigger to solve existing shaping cost.
In order to solve the problems referred to above; the invention provides the reshaping device that a kind of automobile rear sub-frame lower plate negative angle is bilateral; include lower mold seat board, lower cavity die, upper clamping plate and upper cavity die; described upper clamping plate is arranged on the slide block of hydraulic press; upper clamping plate lifting moving is driven by slide block; described upper clamping plate is arranged with cushion block; upper cushion block is arranged with upper cavity die; it is provided with lower cavity die on described lower mold seat board; the middle part of described lower cavity die is provided with guide pillar; being provided with punch dnockout core on the guide pillar of described lower cavity die, described punch dnockout core is arranged with flexible member.
Further improvement is that: described upper clamping plate, upper cushion block and upper cavity die lift displacement with the lifting of slide block.
Further improvement is that: described guide pillar is connected in the pilot hole of upper cavity die, described guide pillar is reserved with gap with the bottom of pilot hole.
Further improvement is that: described punch dnockout core can carry out lifting displacement on guide pillar.
The invention has the beneficial effects as follows: the present invention is provided by front shaping mould mechanism and carries out shaping to automobile rear sub-frame lower plate negative angle is bilateral, satisfactory for result, and mould structure is simple, cost is relatively low, die life is longer, operation is the simplest, stability is higher.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Wherein: 1-lower mold seat board, 2-lower cavity die, 3-upper clamping plate, 4-upper cavity die, 5-guide pillar, 6-punch dnockout core, 7-punch dnockout core, 8-flexible member, 9-pilot hole.
Detailed description of the invention
In order to deepen the understanding of the present invention, being further described the present invention below in conjunction with embodiment, the present embodiment is only used for explaining the present invention, is not intended that limiting the scope of the present invention.
As shown in Figure 1, present embodiments provide the reshaping device that a kind of automobile rear sub-frame lower plate negative angle is bilateral, include lower mold seat board 1, lower cavity die 2, upper clamping plate 3 and upper cavity die 4, described upper clamping plate 1 is arranged on the slide block of hydraulic press, upper clamping plate 3 lifting moving is driven by slide block, described upper clamping plate 3 is arranged with cushion block 5, upper cushion block 5 is arranged with upper cavity die 4, it is provided with lower cavity die 2 on described lower mold seat board 1, the middle part of described lower cavity die 2 is provided with guide pillar 6, it is provided with punch dnockout core 7 on the guide pillar 6 of described lower cavity die, described punch dnockout core 7 is arranged with flexible member 8.Described upper clamping plate 3, upper cushion block 5 and upper cavity die 4 carry out lifting displacement with the lifting of slide block.Described guide pillar 6 is connected in the pilot hole 9 of upper cavity die 4, and described guide pillar is reserved with gap with the bottom of pilot hole.Described punch dnockout core 7 can carry out lifting displacement on guide pillar 6.
When press slide rises setting height; upper clamping plate 3, upper cushion block 5 and upper cavity die 4 separate with lower cavity die 2 with slide block; it is up that punch dnockout core 7 acts on downward guide pillar 6 at flexible member 8; operator is enclosed within the Rear secondary frame for vehicle lower plate treating integer on punch dnockout core 7; the product orientation mode of the application is profile location; slide block down; first during guide pillar 6 enters the pilot hole 9 of upper cavity die 4; the part of fovea superior 4 mould contact immediately; slide block continues traveling downwardly; reforming process starts, and when upper cavity die 4 and lower cavity die 2 are all fitted with punch dnockout core 7, integer process terminates；Slide block is up, and it is up that punch dnockout core 7 acts on downward guide pillar 6 at flexible member 8, and operator takes off the Rear secondary frame for vehicle lower plate of integer from integer punch dnockout core, and an integer jig frequency completes.
The present invention is provided by front shaping mould mechanism and carries out shaping to automobile rear sub-frame lower plate negative angle is bilateral, satisfactory for result, and mould structure is simple, cost is relatively low, die life is longer, operation is the simplest, stability is higher.
