Abstract
The utility model discloses a kind of have allow the mould of hollow structure, belong to technical field of mold, for solving the rebound phenomenon that existing mould produces in high-strength steel stamping parts forming process, problems such as the formed precision of high strength steel plate stamping parts and Quality Down and designing.This has allows the mould of hollow structure comprise patrix insert and counterdie insert, and the bending forming place of described counterdie insert is provided with the sky portion that allows, described in allow between sky portion and stamping parts and be formed with gap.The utility model effectively controls the rebound phenomenon in high-strength steel stamping parts forming process, improves formed precision and the quality of high strength steel plate stamping parts.
Description
Technical field
The utility model relate to a kind of have allow the mould of hollow structure, belong to technical field of mold.
Background technology
Along with the development of automobile industry, loss of weight consumption reduction and raising security become the Main Trends of The Development of auto manufacturing, in order to realize automotive energy-saving emission-reducing, security height waits multiple target, starts to use high strength steel in enormous quantities in auto industry, but this kind of high strength steel toughness is strong, in the process adopting mould punching body of a motor car part, high strength steel sheet material can produce rebound phenomenon, causes reaching predetermined angle, affect the formed precision of part, cause part quality significantly to decline.
Utility model content
The purpose of this utility model be propose a kind of have allow the mould of hollow structure, effectively can control the rebound phenomenon in high-strength steel stamping parts forming process, improve formed precision and the quality of high strength steel plate stamping parts.
For reaching this object, the utility model by the following technical solutions:
The utility model provide a kind of have allow the mould of hollow structure, comprise patrix insert and counterdie insert, the bending forming place of described counterdie insert is provided with the sky portion that allows, described in allow between sky portion and stamping parts and be formed with gap.
Further, the bending angle in sky portion is allowed to reserve 3-6 ° than the preset curve angle of described stamping parts described in.
Further, the bending angle in sky portion is allowed to reserve 5 ° than the preset curve angle of described stamping parts described in.
Further, the gap formed between described patrix insert and holding pad is 0.4-0.5mm.
Further, the gap formed between described patrix insert and holding pad is 0.45mm.
The beneficial effects of the utility model are:
(1) the utility model provide a kind of have allow the mould of hollow structure, the bending forming place of counterdie insert is provided with the sky portion that allows, sky portion is allowed to be the gap formed between stamping parts and counterdie insert, effectively control the rebound phenomenon in high-strength steel stamping parts forming process, improve formed precision and the quality of high strength steel plate stamping parts.
(2) bending angle in sky portion is allowed to reserve 3-6 ° than the preset curve angle of stamping parts, make high-strength steel sheet material can to lower mould direction along bending forming fillet surplus campaign, the design of this structure reduce the vertical flange of high-strength steel stamping parts shaping after flange resilience amount.
Accompanying drawing explanation
Fig. 1 is that having of providing of the utility model embodiment one allows the structural representation of mould of hollow structure;
Fig. 2 is the structural representation of the qualified stamping parts that the utility model embodiment one provides;
Fig. 3 is the structural representation of the stamping parts of the generation rebound phenomenon that the utility model embodiment one provides.
In figure, 1, patrix insert; 2, counterdie insert; 3, sky portion is allowed; 4, stamping parts; 5, holding pad.
Detailed description of the invention
The technical solution of the utility model is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
Embodiment one:
Present embodiments provide a kind of have allow the mould of hollow structure, as shown in Figure 1-Figure 3, it comprises patrix insert 1 and counterdie insert 2, the bending forming place of counterdie insert 2 is provided with the sky portion 3 that allows, allow between sky portion 3 and stamping parts 4 and be formed with gap, the bending angle that the setting in this gap can make stamping parts bending forming reach predetermined, effectively controls the rebound phenomenon in high-strength steel stamping parts forming process, improves formed precision and the quality of high strength steel plate stamping parts.
Allow the gap length in sky portion 3 can according to high-strength steel performance and stamping parts shape shaping to stamping parts after springback capacity design.
In the present embodiment, sky portion 3 is allowed to be designed to bending structure, its bending angle reserves 3-6 ° than the preset curve angle of stamping parts 4, the present embodiment is preferred, the bending angle in sky portion 3 is allowed to reserve 5 ° than the preset curve angle of stamping parts 4, make high-strength steel sheet material can to lower mould direction along bending forming fillet surplus campaign, the design of this structure reduce the vertical flange of high-strength steel stamping parts shaping after flange resilience amount.
In addition, in the present embodiment, after being heated to prevent mould die holder spalling or make insert be subject to squeeze distortion, therefore, be formed with gap between patrix insert 1 and holding pad 5, gap is 0.4-0.5mm.Preferably, the gap formed between patrix insert 1 and holding pad 5 is 0.45mm.
The sky portion that allows of the present utility model is not limited to above-mentioned bending structure, hollow structure can also be allowed for other, as long as make, between mould and stamping parts product, there is gap, effectively can control the rebound phenomenon that high-strength steel stamping parts produces in forming process, in addition, the gap length formed between patrix insert and holding pad can design according to the insert of different size, and for the insert of different size, this gap width is different.
Below know-why of the present utility model is described in conjunction with specific embodiments.These describe just in order to explain principle of the present utility model, and can not be interpreted as the restriction to the utility model protection domain by any way.Based on explanation herein, those skilled in the art does not need to pay performing creative labour can associate other detailed description of the invention of the present utility model, and these modes all will fall within protection domain of the present utility model.
