Abstract
The utility model discloses a bending forming die, which comprises an upper die and a lower die. The bending forming die is characterized in that a core pulling mechanism is arranged inside the lower die and comprises a sliding chute and two sliding blocks, and the sliding chute and the sliding blocks are positioned on the lower die; the bottom part of the sliding chute is provided with an elastic device; the sliding blocks are positioned on the elastic device; and a cavity is formed between the two sliding blocks. The bending forming die has a simple structure and is convenient to use; and the surface of a formed workpiece does not have impression and scratch.
Description
Technical field
The utility model relates to a kind of mould, especially a kind of bending and forming mould.
Background technology
Switch board door-plate and side plate need form stiffened edge with bending usually, and existing bending and forming step is as follows: with common Bending Mould workpiece is converted into 30 ° earlier, as shown in Figure 1; Again with shaping dies with the stiffened edge press forming, as shown in Figure 2.By present existing process method and mould scheme following shortcoming is arranged in process: 1. when existing common shaping dies was shaped, because of there not being automatic discharge unit, workpiece can be stuck in mould, and as shown in Figure 2, and surface of the work has scratch and distortion easily; 2. this type of mould can only be processed the part of identical forming dimension, and flexible adjustable is poor, and shared property is poor, so lost its extensive use in the industry.
Summary of the invention
The utility model purpose is: provide a kind of simple in structure, easy to use, a kind of bending and forming mould of high efficiency.
The technical solution of the utility model is: a kind of bending and forming mould, comprise upper die and lower die, it is characterized in that, be provided with core-pulling mechanism in the described counterdie, described core-pulling mechanism comprises chute and two slide blocks that are positioned on the counterdie, described chute bottom is provided with elastic device, and described slide block is positioned on the described elastic device, forms die cavity between the described slide block.
Further, described chute bottom is provided with guide pillar, and described slide block is positioned at described guide pillar both sides.
Further, described elastic device is for regulating the spring of height and coefficient of elasticity.
Further, the taper pin angle of described slide block is 100 degree-140 degree.
Further, there is guiding rib on the inclined-plane of described slide block, and there is the gathering sill with described guiding rib coupling on the inclined-plane of described chute.
The utility model has the advantages that:
1. can require counterdie is carried out different settings according to different product sizes, so not only save the die sinking cost greatly, also shorten entire die simultaneously and designed and developed the process-cycle;
2. the back surface of the work that is shaped does not have impression and scratches, and outward appearance is beautiful, has improved client's satisfaction.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is for carrying out the 30 bending schematic diagrames of spending to switch board door-plate and side plate.

Wherein: 1 patrix; 2 counterdies; 3 workpiece; 4 elastic devices; 5 slide blocks; 6 guide pillars; 7 die cavities.
The specific embodiment
Embodiment: bending and forming mould as shown in Figure 3, comprise patrix 1 and counterdie 2, be provided with core-pulling mechanism in the counterdie 3, core-pulling mechanism comprises and is positioned on the counterdie chute and two slide blocks 5 of 2, the chute bottom is provided with guide pillar 6 and elastic device 4, elastic device 4 is positioned at the both sides of guide pillar 6, and slide block 5 is positioned on the elastic device 4, forms die cavity 7 between the slide block 5.In the present embodiment, elastic device has adopted the spring that can regulate height and coefficient of elasticity.The angle on the inclined-plane of slide block 5 is 100 degree-140 degree, and the too little then mold thickness of angle increases, and angle too greatly then slide block is stressed too big, lowers the slide block life-span; In the present embodiment, the angle on the inclined-plane of slide block 5 is 100 degree.In order to make slide block movement on fixing track, the inclined-plane of slide block can also be provided with guiding rib, and there is the gathering sill with this guiding rib coupling on the inclined-plane of chute.
During duty: the first step is converted into 30 ° with common Bending Mould with workpiece; In second step, on first step basis, workpiece 3 enters in the die cavity 7 of counterdie 2 under the guide effect of patrix 1 pressure and counterdie 2; In the 3rd step, because the extruding of 1 pair of counterdie of patrix, the die cavity 7 between slide block will narrow down, thereby finishes the further shaping to workpiece 3, has reached the forming effect of expection, as shown in Figure 4; In the 4th step, bending finishes, and when patrix moved upward, elastic device promoted slide block and moves upward, and die cavity 7 broadens, thereby finishes automatic discharging, and workpiece can not block, as shown in Figure 5.
Above embodiment only is the utility model a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
