Description

A kind of truck frame crossbeam longeron one-shot forming springback control device
Technical field
The utility model relates to technical field of mold, is specially a kind of truck frame crossbeam longeron one-shot forming springback control device.
Background technology
Brake forming is one of forming method the most general in Sheet Metal Forming Technology, applies quite extensive.In stamping parts of automobile, many parts are had mainly to be obtained by bending forming, as longeron, crossbeam inner and outer plates etc.Because the effect of elastic recovery and residual stress inevitably produces rebound phenomenon after sheet metal bending is shaped, directly affects the quality of stamping parts, comprise presentation quality assembly performance and dependability etc.And resilience defect is problem very rambunctious in sheet forming.Show in numerous scientific research; the main factor wherein affecting molding resilience is then the size of the radius of corner of die slide block and punch; and traditional springback control device all adjusts without to radius of corner; and; traditional springback control device input cost is high, is unfavorable for large-scale popularization.
Utility model content
The purpose of this utility model is to provide a kind of truck frame crossbeam longeron one-shot forming springback control device, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of truck frame crossbeam longeron one-shot forming springback control device, comprise cope match-plate pattern, the bottom of described cope match-plate pattern is fixed with punch retainer by first nut in left side and the alignment pin on right side, the bottom of described punch retainer is fixed with punch, the left and right sides of described punch retainer to be coordinated with bolt by location-plate and is fixed with die, the both sides of described punch retainer are fixed with guide pin bushing, and the top of guide pin bushing is fixed on the bottom of cope match-plate pattern, the bottom of described guide pin bushing is socketed with guide pillar, the bottom of described punch is provided with die slide block, the bottom of described die is fixed with die block, the bottom of described die slide block is connected with Compress Spring by the second nut, and Compress Spring is fixed on the bottom of lower bolster, the top of described lower bolster is fixed together by the bottom of bolt and die slide block.
Preferably, described Compress Spring is cylindrical helical, and Compress Spring to be coordinated with bolt by spring base and the bottom of lower bolster is fixed together.
Preferably, the bottom of described punch is fixed together by the dovetail groove of clamping or the mode be spirally connected and punch retainer bottom.
Compared with prior art, the beneficial effects of the utility model are: this truck frame crossbeam longeron one-shot forming springback control apparatus structure is simple, and die and punch are coordinated by oat tail groove structure, make more to be conducive to more mold exchange, meet popular different demands; Further, adopt this structure can easily with changing die slide block, by with the die slide block and the punch that change different radii; thus well reduce radius of corner to the impact of mould resilience, make end product quality better, and; this installation cost is low, is more convenient for promoting on a large scale.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1 cope match-plate pattern, 2 first nuts, 3 alignment pins, 4 punch retainers, 5 punch, 6 guide pin bushings, 7 guide pillars, 8 location-plates, 9 dies, 10 die slide blocks, 11 die blocks, 12 second nuts, 13 Compress Springs, 14 lower bolsters.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the utility model provides a kind of technical scheme: a kind of truck frame crossbeam longeron one-shot forming springback control device, comprise cope match-plate pattern 1, the bottom of cope match-plate pattern 1 is fixed with punch retainer 4 by first nut 2 in left side with the alignment pin 3 on right side, the bottom of punch retainer 4 is fixed with punch 5, the bottom of punch 5 is fixed together by the dovetail groove of clamping or the mode be spirally connected and punch retainer 4 bottom, the left and right sides of punch retainer 4 to be coordinated with bolt by location-plate 8 and is fixed with die 9, die 9 and punch 5 are coordinated by oat tail groove structure, make more to be conducive to more mold exchange, meet popular different demands, the both sides of punch retainer 4 are fixed with guide pin bushing 6, and the top of guide pin bushing 6 is fixed on the bottom of cope match-plate pattern 1, the bottom of guide pin bushing 6 is socketed with guide pillar 7, the bottom of punch 5 is provided with die slide block 10, the bottom of die 9 is fixed with die block 11, the bottom of die slide block 11 is connected with Compress Spring 13 by the second nut 12, and Compress Spring 13 is fixed on the bottom of lower bolster 14, Compress Spring 13 is in cylindrical helical, and Compress Spring 13 to be coordinated with bolt by spring base and the bottom of lower bolster 14 is fixed together, the top of lower bolster 14 is fixed together by the bottom of bolt and die slide block 11, adopt this structure can easily with changing die slide block 10, by with the die slide block 10 and the punch 5 that change different radii, thus well reduce radius of corner to the impact of mould resilience, make end product quality better, and, this installation cost is low, be more convenient for promoting on a large scale.
