Description

A kind of balance weight assembly of car panel die

Technical field

The utility model relates to a kind of balance weight assembly, relates in particular to a kind of balance weight assembly of car panel die, belongs to the car panel die field in the machining impact technology.

Background technology

Along with high development of social economy, the continuous development of automobile industry, its quality and specification requirement to the mould of automobile metal plate work of people is also increasingly high.Especially for the employed drawing die of automobile metal plate work moulding, the sheet metal component surface quality required precision after its stationarity to car panel die, precision and the moulding is increasingly high.

In order to solve the stationarity of full-sized car cladding member mold, car panel die has all designed balance weight basically.But mostly the balance weight that uses at present is the flat circle bench-type, and it can adjust the stationarity of car panel die, but can't guarantee the car panel die high accuracy of die face up and down.

In the prior art, produce balance and the dimensional accuracy of keeping profile in the sheet metal component process, generally adopt balance weight and guide pillar guide pin bushing to use simultaneously in order to realize car panel die.Just increase the manufacturing cost of car panel die so virtually, also increased the workload of pincers worker simultaneously.And, also can produce certain wearing and tearing between its guide pillar guide pin bushing along with the continuous use of car panel die, cause positioning accuracy not high.

In view of this, be necessary the balance weight assembly of existing car panel die is improved, to address the above problem.

The utility model content

The purpose of the utility model is to provide a kind of balance weight assembly of car panel die, and it can reduce the manufacturing cost of car panel die, improves the positioning accuracy of car panel die, reduces artificial use amount.

For realizing above-mentioned utility model purpose, the utility model provides a kind of balance weight assembly of car panel die, and said balance weight assembly comprises:

First balance weight, one of which end are provided with a conical convex extension part;

Second balance weight, one of which end are provided with a conical portion that is arranged with, in order to accommodate the convex extension part of said first balance weight.

As the further improvement of the utility model, the cone angle that the cone angle of the conical convex extension part of first balance weight and second balance weight conical is arranged with portion is identical.

Compared with prior art; The beneficial effect of the utility model is: through first balance weight being arranged to have a conical convex extension part; And utilize the taper shape portion of being arranged with of second balance weight to position guiding; The effect that has the balance car panel die when simultaneously, first balance weight contacts with second balance weight fully.Thereby reduce the manufacturing cost of car panel die, improve the positioning accuracy of car panel die, reduce artificial use amount.

The specific embodiment

Below in conjunction with each embodiment shown in the drawings the utility model is elaborated; But should be noted that; These embodiments are not the restriction to the utility model; The function that those of ordinary skills do according to these embodiments, method, or structural equivalent transformation or substitute all belong within the protection domain of the utility model.

Ginseng Fig. 1 is to balance weight assembly one specific embodiment of a kind of car panel die of the utility model shown in Figure 3.In this embodiment,

A kind of balance weight assembly 100 of car panel die, the balance weight assembly 100 of said a kind of car panel die comprises: first balance weight 10, one of which end are provided with a conical convex extension part 101; Second balance weight 20, one of which end are provided with a conical portion 201 that is arranged with, in order to the convex extension part 101 of accommodating said first balance weight.

Ginseng Fig. 4 to Fig. 6, in this embodiment, the cone angle beta that the cone angle of the conical convex extension part 101 of first balance weight 10 and second balance weight 20 conical is arranged with portion 201 is identical.

In this embodiment; A kind of balance weight assembly 100 of car panel die is produced in the course of work in the sheet metal component at car panel die; Patrix (not shown) is when constantly moving down; First balance weight 10 moves down with holding pad (not shown), contacts with the second balance weight assembly 20.In both contact processes, the portion that is arranged with 201 shapes of the convex extension part 101 of first balance weight 10 capable of using and second balance weight 20 are led, and prevent that the punch-die profile of car panel die from squinting, and make the plate of going out defective.The effect that has the balance car panel die when simultaneously, first balance weight 10 contacts with second balance weight 20 fully.

First balance weight 10 also is provided with two screw mounting holes 11 and two dowel holes 12, and it locks in the upper bolster (not shown) of drawing die through screw (not shown).Second balance weight 20 also is provided with two screw mounting holes 21 and two dowel holes 22, and it locks in the die shoe (not shown) of car panel die through screw (not shown).In this embodiment, this second balance weight 20 comprises that also a processing dodges hole 23.

The listed a series of detailed description of preceding text only is specifying to the feasibility embodiment of the utility model; They are not the protection domain in order to restriction the utility model, allly do not break away from equivalent embodiment or the change that the utility model skill spirit done and all should be included within the protection domain of the utility model.
