Abstract
The invention belongs to a stamping die, in particular to a boss stamping die for an automobile plate spring. The boss stamping die comprises a die handle, an upper die part, a lower die part, a guide post and a guide sleeve, wherein a material pressing plate is arranged on the lower end surface of an upper fixed plate of the upper die part, and arc-shaped ports are arranged on the two sides of the material pressing plate; a concave groove of a female die of the lower die part is matched with the arc-shaped ports on the material pressure plate for forming a space for forming a boss by stamping; and a cushioning device is further arranged at the lower end of the lower die part. According to the stamping die disclosed by the invention, the boss can be stamped for the automobile plate spring, and when the stamping die is stuck, discharge can be fast and conveniently performed.
Description
Technical field
The invention belongs to diel, be specifically related to the diel of a kind of leaf springs of car boss.
Background technology
Mostly the flexible member of automobile suspension system is leaf spring, is lined with rubber between common two leaf springs, in the automobile traveling process; Rubber comes off between leaf spring easily; Increased the friction between leaf spring, shortened the service life of leaf spring, the side of leaf spring has been stamped out boss for this reason rubber is fixed on the leaf spring; But also there is not such diel at present; And present diel is in punching course, the phenomenon that can occur getting stuck.
Summary of the invention
The technical problem that the present invention will solve provides and a kind ofly can leaf springs of car have been struck out boss, and the leaf springs of car boss diel of easy-unloading.
In order to solve the problems of the technologies described above, the present invention provides the diel of a kind of leaf springs of car boss, comprises die shank, upper mould part, lower mould part, guide pillars and bushes, and the upper mounted plate lower surface of said upper mould part is provided with holding pad, and the holding pad both sides are provided with arc port; The Baltimore groove of the die of lower mould part cooperates with arc port on the holding pad and forms the space that strikes out boss; The lower end of lower mould part also is provided with buffer unit, and said buffer unit comprises mounting plate, bottom plate, leaf spring and the nut that connects through screw rod, and buffer unit is connected the lower surface of the lower bolster of lower mould part through push rod and screw rod.
Adopt the leaf springs of car boss diel of technique scheme to have following advantage: 1 with respect to mould of the prior art; Can realize the processing to the leaf springs of car boss, it promptly is the boss shape of leaf spring punching press that the arc port of holding pad and the Baltimore groove of die form closed figure; 2, when occurring getting stuck accident, can carry out discharging easily and fast; Because the setting of buffer unit; When occurring getting stuck,, accomplish the spring unloading that is got stuck because the effect of spring with the bottom plate place of load transfer to lower mould part, can be accomplished the decline of lower bolster through loading and unloading bottom plate; 3, easy to operate, because the parts in the buffer unit all connect through screw rod, when dismounting, turn on nut and can counterdie be dismantled.
As further technological improvement of the present invention, the side of said die is provided with the lateral register plate on the bottom plate that is fixed on lower mould part, and the setting of location-plate can make the leaf spring that is stamped fall to being positioned at stamping position accurately.
As further technological improvement more of the present invention, be provided with spring between the upper mounted plate of said holding pad and upper mould part, utilize the expansion performance of spring can realize carrying out effectively fixing to the leaf spring steel plate of different-thickness.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further detailed explanation:
Fig. 1 is the structural representation of leaf springs of car boss of the present invention diel.
The specific embodiment
As shown in Figure 1, the present invention provides the diel of a kind of leaf springs of car boss, comprises die shank 6, upper mould part, lower mould part, guide pillars and bushes, and upper mounted plate 2 lower surfaces of said upper mould part are provided with holding pad 21, and holding pad 21 both sides are provided with arc port; The Baltimore groove of the die 8 of lower mould part cooperates with arc port on the holding pad 21 and forms the space that strikes out boss; The lower end of lower mould part also is provided with buffer unit, and said buffer unit comprises mounting plate 14, bottom plate 15, leaf spring 16 and the nut 18 that connects through screw rod, and buffer unit is connected the lower surface of the lower bolster 12 of lower mould part through push rod 13 and screw rod 17.
Embodiment one: at first confirm the stamping position of leaf spring, make the punching press position be positioned at the scope of holding pad 21 arc ports and die Baltimore groove, start punch press and accomplish the punching press to leaf spring.
Embodiment two: the stamping position of at first confirming leaf spring; Make the punching press position be positioned at the scope of holding pad 21 arc ports and die Baltimore groove; Start punch press and accomplish punching press leaf spring; When occurring getting stuck, can accomplish the decline of lower bolster 12 through loading and unloading bottom plate 15, accomplish the spring unloading that is got stuck.
Above-described only is preferred implementation of the present invention; Should be understood that for a person skilled in the art; Under the prerequisite that does not break away from structure of the present invention, can also make some distortion and improvement, these can not influence effect and practical applicability that the present invention implements.
