Abstract

The invention relates to a counterbalance which is applied to an automotive cover panel and is arranged between an upper die and a lower die for preventing the movement of profiles of the upper die and the lower die. The automotive cover panel comprises a concave V-shaped counterbalance, a convex V-shaped counterbalance and a V-shaped counterbalance gasket. The angle between two inclined planes of the vertical section of the convex V-shaped counterbalance is 120 minus or plus 5 degrees. The V shape of concave and convex parts is in an open-typed contact. The gasket is fixed with the concave V-shaped counterbalance. With the counterbalance adopted, the profiles of the upper die and the lower die can be prevented from moving, and the production cost is lowered.

Description

The V-arrangement balance weight

Technical field:

The present invention relates to a kind of automobile panel, definite saying so is installed in and guarantees the balance weight that the upper and lower mould profile is not gone here and there between the upper and lower mould.

Background technology:

In the existing automobile die structure, because the automobile panel particularly mould of outer covering piece is very high to the requirement of profile, usually guaranteeing that the upper and lower mould profile all can not install the taper balance weight under the situation of play, the taper balance weight is made of recessed balance weight, protruding balance weight, recessed balance weight tips upside down on the protruding balance weight, concavo-convex contact-making surface is conical in the taper balance weight, and angle is 90 °, so taper balance weight concave portions must adopt special mill processing method, form processing request to circular cone is also very high, technology difficulty is bigger, and production cost is too high.

Based on above reason, the taper balance weight exists under the form of circular cone processing request very high, the problem that manufacture difficulty is big.

Summary of the invention:

The present invention is intended to solve above-mentioned taper balance weight processing request height, and the drawback that manufacture difficulty is big provides a kind of V-arrangement balance weight, has solved the problem of its existence, reaches to be easy to the purpose making, reduce cost.

For achieving the above object, the technical solution used in the present invention is as follows:

The V-arrangement balance weight comprises the recessed balance weight of V-arrangement, the protruding balance weight of V-arrangement, it is characterized in that: the recessed balance weight of described V-arrangement is that open type contacts with the contact-making surface of the protruding balance weight of V-arrangement.

Protruding balance weight of described V-arrangement and the recessed balance weight sunk part of V-arrangement contact-making surface are flat roof shape, promptly

Shape, the length direction two ends open wide.

Angle between two inclined-planes, the protruding balance weight of described V-arrangement longitudinal section is 120 ° ± 5 °.

The protruding balance weight of described V-arrangement bottom is equipped with pad.

The invention has the advantages that:

One, the concave-convex part has then adopted the open type contact, has reduced difficulty of processing and manufacturing cost;

Two, the angle of concavo-convex contact changes, and has made things convenient for processing technology;

Three, the present invention is equipped with pad in the recessed balance weight of V-arrangement bottom, can compensate adjusting;

Four, V-arrangement (trapezoidal) contact-making surface lifting surface area is bigger more stable.

The specific embodiment:

What the present invention proposed is a kind of V-arrangement balance weight of fixedly upper and lower mould profile.

The V-arrangement balance weight comprises the recessed balance weight 5 of V-arrangement, the protruding balance weight 3 of V-arrangement, V-arrangement balance weight pad 4.

The V-arrangement balance weight is installed in and prevents upper and lower mould profile play between the upper and lower mould, particularly to the mould of the demanding outer covering piece of profile.Punching is installed in situation on the eccentric swage that the taper balance weight also is installed usually is convenient to drift and guarantee not play of profile for lewisson.

V-arrangement balance block structure such as Fig. 5, wherein the V-arrangement re-entrant angle degree of the recessed balance weight 5 of V-arrangement is 120 ° ± 5 °, with 2 M10 and 2

Pin fastening.The protruding V-arrangement angle of the protruding balance weight 6 of V-arrangement is 120 ° ± 5 °, with 2 M10 and 2

Pin fastening, guarantee to fit tightly with the recessed balance weight 8 of V-arrangement.It is raw material that the V-arrangement balance weight can be used T10A (carbon tool steel), and hardness is good, and price is low.V-arrangement balance weight pad 4 materials can be used the 45# steel, and V-arrangement balance weight pad 4 is fixed as an integral body with recessed V-arrangement balance weight 5 usefulness counter-sunk screws, and when the V-arrangement balance weight need be regulated, mill V-arrangement balance weight pad 4 was regulated the thickness of pad, general regulated quantity＜0.5mm.

The inclined-plane of V-arrangement balance weight is the open type contact, and open type contact described here is meant that transversely two ends are two contact inclined-planes, promptly

Shape, the length direction two ends open wide.Be compared to the conical contact face of taper balance weight, the complexity of manufacturing process and manufacturing cost all have significantly reduction.In processing V-arrangement recessed balance weight 5, so adopt 120 ° of whiles of wide-angle also to satisfy concavo-convex working portion to another damage of to be processed to have certain angle to prevent toward the problem of the play of a direction in order to hide emery wheel.On manufacturing process, for the taper balance weight of approximate size, the recessed balance weight 5 of V-arrangement is bigger than the area of the protruding balance weight 1 of taper, recessed balance weight 2 engagements of taper with the field of conjugate action of the protruding balance weight 3 of V-arrangement.When if the joint place width is identical, the area of contact of V-arrangement balance weight is more protruding than taper balance weight, concave portion area of contact ratio is big, and in other words the lifting surface area of V-arrangement balance weight is more stable greatly.

For bigger part, when arranging the V-arrangement balance weight, need four, the mode of arranging such as Fig. 4, just passable for 3 of smaller arrangement of parts.

Claims (4)

1, V-arrangement balance weight comprises the recessed balance weight of V-arrangement, the protruding balance weight of V-arrangement, it is characterized in that: the recessed balance weight of described V-arrangement is that open type contacts with the contact-making surface of the protruding balance weight of V-arrangement.
