Description
Technical field
The utility model relates to a kind of mould, especially a kind of auto parts mould, specifically hanger general assembly single-piece hollow circular-tube internal diameter shaping mould after a kind of leaf spring.
Background technology
At present, along with automobile industry is increasingly competitive, each auto vendor is for automobile product parts quality requirement also in raising, and the dimensional requirement as hanger general assembly single-piece hollow circular-tube after the leaf spring of Chang'an company is also promoting.
Because the existing hollow circular-tube internal diameter size tolerance standard commercially bought differs, cause the requirement that cannot reach Chang'an company part size by existing production technology; The hollow circular-tube tolerance that present market is purchased is generally about 50-60 silk, such tolerance cannot meet the quality standard of Chang'an company completely, need manually entirely to examine product, to prevent from occurring in total process of assembling the problem that dimensional discrepancy cannot be installed to meet the demands.In order to head it off, at present conventional method is entered and is carried out bore hole with lathe boring cutter, reaches product quality requirement, this method not only wastes time and energy, and efficiency is extremely low, the output of one day, at about 300-500, cannot reach the general assembly output demand of Chang'an company completely; Therefore in order to avoid above problems, employing mould extrusion not only precision can reach standard-required, and efficiency is higher, is badly in need of a kind of simple shaping mould of exploitation for this reason and improves product quality and production efficiency.
Summary of the invention
The purpose of this utility model is the problem that can not meet instructions for use for existing hollow circular-tube tolerance, designs hanger general assembly single-piece hollow circular-tube internal diameter shaping mould after a kind of leaf spring.
The technical solution of the utility model is:
Hanger general assembly single-piece hollow circular-tube internal diameter shaping mould after a kind of leaf spring, it comprises cope match-plate pattern 1 and lower bolster 2, cope match-plate pattern is provided with dowel hole 3 and die shank 4, it is characterized in that the one side that described cope match-plate pattern 1 is relative with lower bolster is provided with the round punch 5 that hanger general assembly single-piece hollow circular-tube internal diameter after diameter and leaf spring is consistent, described lower bolster 2 is provided with the guide pillar 6 matched with dowel hole 3 and the limiter 7 limiting round punch stroke, lower bolster between guide pillar is provided with hollow circular-tube location-plate 8, hollow circular-tube location-plate 8 is provided with stripper 9.
The locating slot of described hollow circular-tube location-plate 8 is semicircular arc.
Described lower bolster is provided with the groove or projection 10 of locating for hollow circular-tube 11.
Described limiter 7 is integral type Step Shaft structure with guide pillar 6.
The beneficial effects of the utility model:
1. the utility model can improve output (3000/ day) greatly and turned over several times than original output.
2. the utility model can guarantee product internal diameter size, and ensure the quality of products (original internal diameter 29.5mm, present internal diameter 30.1mm) meets cubing requirement.
3. greatly reducing human resources, do not need inspector entirely to examine completely, also do not need special lathe personnel to carry out bore hole.
4. mould structure is simple, manufactures easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the top view of hollow circular-tube location-plate of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in Figure 1-2.
Hanger general assembly single-piece hollow circular-tube internal diameter shaping mould after a kind of leaf spring, it comprises cope match-plate pattern 1 and lower bolster 2, cope match-plate pattern is provided with dowel hole 3 and die shank 4, the one side that described cope match-plate pattern 1 is relative with lower bolster is provided with the round punch 5 that hanger general assembly single-piece hollow circular-tube internal diameter after diameter and leaf spring is consistent, described lower bolster 2 is provided with the guide pillar 6 matched with dowel hole 3 and the limiter 7 limiting round punch stroke, limiter 7 and guide pillar 6 both can be the split-type structural shown in Fig. 1, also both can be designed to the Step Shaft structure of integral type, lower bolster between guide pillar is provided with semicircular arc hollow circular-tube location-plate 8, as shown in Figure 2, hollow circular-tube location-plate 8 is provided with stripper 9.For the ease of the operator placement of hollow circular-tube 11, the groove or projection 10 of locating for hollow circular-tube 11 can be set on lower bolster.
Using method of the present utility model is:
1. hollow circular-tube being placed on hollow circular-tube location-plate, locating to ensure that hollow circular-tube keeps concentric with round punching;
2. when punch press is started working, suppress from top to bottom, circle sweeps away pressure by the hollow circular-tube concentric with him, completes the expansion of hollow circular-tube;
3. last when punching machine presses is to work limit device place, by stripper, its hollow circular-tube is unloaded, last patrix backhaul;
Above operation principle repeatedly, just can carry out batch production and can reach product quality requirement.
The utility model does not relate to the part prior art that maybe can adopt all same as the prior art and is realized.
