Abstract
The utility model relates to an ejector rod hydraulic balance device of an automobile external covering part drawing molding die, comprising at least four hydraulic devices which are communicated with each other by oil pipes; the hydraulic pressure consists of a base, a cylinder body, a piston, a sealing ring and a connecting rod; the lower end of the connecting rod is connected with the upper surface of the piston and the upper end thereof extends out of the cylinder body. The ejector rod hydraulic balance device is characterized in that the cylinder body below the piston is internally filled with hydraulic oil; the side wall of the cylinder body below the piston is provided with four oil pipe joints. The ejector rod hydraulic balance device of the utility model has the advantages of solving the problems of non-uniform force-bearing of the die pressing edge and large site debugging difficulty, saving the die debugging and die replacing time at the same time, effectively reducing the rework rate and the reject rate of the parts, and improving the production stability and working efficiency. Furthermore, the precision of the pressing machine is effectively ensured, and the die and the pressing machine are protected.
Description
Technical field
The utility model relates to the draw forming die annex, is specifically related to the post rod hydraulic pressure balancing device of exterior cladding element draw forming die of vehicle.
Background technology
The production of the large-scale outer covering piece of automobile generally needs the 3-5 procedure, and among these operations, first procedure is the drawing and moulding operation, and the drawing and moulding operation plays the effect of wanting to the pass to the product surface state.The reason that influences the formed product poor effect is more, one of them chief reason is a mould unbalance stress in the course of the work, causes material to flow and fluctuation occurs, has therefore influenced molding effect to a great extent, the relatively poor product needed of molding effect is reprocessed, even scraps.This has not only brought huge cost loss, also becomes the bottleneck that the restriction product quality improves.Simultaneously, owing to be subjected to the restriction of aspects such as press equipment precision, cause the debugging difficulty of draw forming die greatly especially, this type of problem also becomes the bigger difficult problem of technical staff's resistance.
The utility model content
The purpose of this utility model provides a kind of post rod hydraulic pressure balancing device of exterior cladding element draw forming die of vehicle, and it can improve the stressed unbalanced situation of draw forming die, reduces the field adjustable difficulty, improves the formed product quality.
The post rod hydraulic pressure balancing device of exterior cladding element draw forming die of vehicle described in the utility model comprises at least 4 hydraulic means that are communicated with by oil pipe; Described hydraulic means by pedestal, be located by connecting on cylinder body on the pedestal, the piston that cooperates with inboard wall of cylinder block, be located at sealing ring, the lower end below the piston and be connected above the piston, connecting rod that cylinder body is stretched out in the upper end forms, it is characterized in that: in the cylinder body below piston hydraulic oil is housed, the sidewall of the cylinder body below piston is provided with 4 oil connections, can cooperate with oil pipe during connection, can seal when not needing to connect.
The post rod hydraulic pressure balancing device of described exterior cladding element draw forming die of vehicle, the pedestal of each hydraulic means is connected with the supporting plate of draw forming die by screw, and the upper end of the connecting rod of each hydraulic means contacts with the push rod of draw forming die.
Effect of the present utility model is: solved mould flanging unbalance stress, problem that the field adjustable difficulty is big, simultaneously, saved die debugging and mould replacing time, effectively reduced that part is reprocessed and scrappage, improved production stability and operating efficiency.In addition, the forcing press precision is effectively guaranteed, and mould and forcing press also are protected.

Fig. 4 is the structural representation of existing exterior cladding element draw forming die of vehicle.
Fig. 5 is the schematic diagram that the utility model cooperates with exterior cladding element draw forming die of vehicle.
The specific embodiment
Referring to Fig. 1 and Fig. 2, described hydraulic means 8 by pedestal 16, be located by connecting on cylinder body 17 on the pedestal, the piston 11 that cooperates with inboard wall of cylinder block, be located at sealing ring 12, the lower end below the piston and be connected above the piston, connecting rod 10 that cylinder body is stretched out in the upper end forms, hydraulic oil 13 is housed in the cylinder body below piston, and the sidewall of the cylinder body below piston is provided with 4 oil connections 14.
Referring to Fig. 3, the post rod hydraulic pressure balancing device of exterior cladding element draw forming die of vehicle described in the utility model comprises 6 hydraulic means 8 that are communicated with by oil pipe 9.
Referring to Fig. 4, exterior cladding element draw forming die of vehicle is made up of patrix 1, blank holder 2 and counterdie 3, and the lifting of air cushion 5 drives the lifting of supporting plate 6 and push rod 7, then is passed to blank holder 2 after push rod 7 is stressed.Material flows in shaping mould under pressure.If there are aspect reasons such as deviation, push rod height be inconsistent in the machine tool precision, then can cause part push rod upper end to fail to touch with the blank holder bottom connection, cause the blank holder discontinuity equalization.Have a strong impact on the Forming Quality of product.
Referring to Fig. 5, solve the problem of blank holder stress equalization, best scheme is that bascule is arranged at each push rod position above supporting plate.The pedestal 16 of each hydraulic means 8 of the post rod hydraulic pressure balancing device of exterior cladding element draw forming die of vehicle is connected with the supporting plate 6 of draw forming die by screw 15, and 6 hydraulic means 8 that are communicated with oil pipe 9, the upper end of the connecting rod 10 of each hydraulic means contacts with the push rod 7 of draw forming die.Under the forcing press effect, power is passed to piston 11, in order to prevent overflowing of hydraulic oil 13.Because the hydraulic oil below the piston of each hydraulic means communicates, and makes push rod regulate its adjustable height automatically with stressed size, under the effect of hydraulic balance device, can make that blank holder is stressed to reach balanced.
