Abstract
The invention discloses a bending mold and relates to the technical field of mold manufacturing. The bending mold comprises an upper mold base and a lower mold base, wherein the lower end of the upper mold base is sequentially provided with a fixed plate and a concave mold; the concave mold is provided with two opposite press mold boards which extend downwards; a push plate is arranged between the press mold boards and is provided with a bolt which passes through the concave mold and is hung on the fixed plate; the bolt is movably connected with the fixed plate; a movable convex mold with an upper end extending out of a boss to two sides is inserted into the lower mold base; a spring is arranged between the lower end of the movable convex mold and the lower mold base; two swing blocks which are arranged in a mirror way are articulated with the lower part of the boss of the movable convex mold; the free ends of the swing blocks are provided with bent parts which incline outwards; the two sides of the concave mold are provided with two opposite positioning baffles. Compared with the prior art, the bending mold is capable of finishing protecting sheet processing once, and is high in production efficiency, accurate in processing positioning and high in product qualification rate.
Description
Technical field
The present invention relates to technology of die manufacturing field, especially a kind of mould for bent plate.
Background technology
Backplate as shown in Figure 1, include flat board 101 and the riser 102 being attached at described dull and stereotyped 101 two ends downward bendings, support plate 103 is stretched out in the outside bending in lower end of described riser 102.Existing bending mold first by curved for blanket go out riser, and then with another set of mould curved go out support plate, just need can complete the processing of backplate with two molds, production efficiency is low; Locating and machining is inaccurate, and product percent of pass is low.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of bending mold, to solve the low problem of existing bending mold processing backplate production efficiency.
In order to solve the problem, the technical solution used in the present invention is: this bending mold, include upper bolster and die shoe, the lower end of described upper bolster is equipped with fixed head and die successively, described die is provided with stretch out the two pieces of pressuring templates arranged in opposite directions downwards, between two pieces of described pressuring templates, push pedal is housed, described push pedal is equipped with the bolt being mounted on described fixed head through described die, described bolt is flexibly connected with described fixed head; Described die shoe is fitted with boss is stretched out in movable punch from upper end to both sides, between the lower end of described movable punch and described die shoe, spring is housed, two mirrors are hinged with to the swinging block arranged below the boss of described movable punch, the free end of described swinging block is provided with outward-dipping bending part, and the both sides of described die are provided with the two pieces of positioning baffles arranged in opposite directions.
In above-mentioned bending mold technical scheme, technical scheme can also be more specifically: the distance between outside the boss of described pressuring template and described movable punch is greater than the distance between blanket upper and lower end face.
Further, the two ends of described swinging block are equipped with arc surface.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, die of the present invention is provided with stretch out the two pieces of pressuring templates arranged in opposite directions downwards, and between two pieces of pressuring templates, push pedal is housed, push pedal is equipped with the bolt being mounted on fixed head through die, bolt is flexibly connected with fixed head; Die shoe is fitted with boss is stretched out in movable punch from upper end to both sides, between the lower end of movable punch and die shoe, spring is housed, below the boss of movable punch, be hinged with two mirrors to the swinging block arranged, the free end of swinging block is provided with outward-dipping bending part; During work, upper bolster drives die to pressing down push pedal, movable punch upwards pushes up, the two ends of blanket are pressed down bending by two pieces of pressuring templates, and upper bolster continues to press down, and push pedal promotes the downward Compress Spring of movable punch, two swinging blocks outwards swing outside for blanket bending, complete the processing of backplate, use this bending mold to process backplate, production efficiency is high.
2, the both sides of die are provided with the two pieces of positioning baffles arranged in opposite directions, and locating and machining is accurate, and product percent of pass is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of backplate.
Fig. 2 is the structural representation of the embodiment of the present invention.
Fig. 3 is the structural representation that bending mold of the present invention is in bent plate state.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
A kind of bending mold as shown in Figure 2, include upper bolster 1 and die shoe 12, the lower end of upper bolster 1 is equipped with fixed head 2 and die 4 successively, die 4 has stretch out the two pieces of pressuring templates 3 arranged in opposite directions downwards, push pedal 6 is housed between two pieces of pressuring templates 3, push pedal 6 is equipped with the bolt 5 being mounted on fixed head 2 through die 4, bolt 5 is flexibly connected with fixed head 2; Die shoe 12 is fitted with boss is stretched out in movable punch 9 from upper end to both sides, and the distance between outside the boss of pressuring template 3 and movable punch 9 is greater than the distance between blanket upper and lower end face; Between the lower end of movable punch 9 and die shoe 12, spring 10 is housed, two mirrors are hinged with to the swinging block 8 arranged by jointed shaft below the boss of movable punch 9, the free ending tool of swinging block 8 has outward-dipping bending part, the two ends of swinging block 8 are equipped with arc surface, the backing plate 11 be fixed on die shoe 12 is housed between swinging block 8 and die shoe 12, the two pieces of positioning baffles 7 arranged in opposite directions are equipped with in the both sides of die 4, two guide pillars are equipped with in the upper end of die shoe 12, and the guide pin bushing be sleeved on guide pillar is equipped with in the lower end of upper bolster 1.
During work, upper bolster 1 drives die 4 to pressing down push pedal 6, movable punch 9 upwards pushes up, the two ends of blanket are pressed down bending by two pieces of pressuring templates 3, upper bolster 1 continues to press down, and push pedal 6 promotes the movable punch 9 outside swing of Compress Spring 10, two swinging blocks 8 downwards by outside for blanket bending, complete the processing of backplate, as shown in Figure 3; Use this bending mold to process backplate, production efficiency is high; The both sides of die 4 are provided with the two pieces of positioning baffles 7 arranged in opposite directions, and locating and machining is accurate, and product percent of pass is high.
