Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is described in further detail.
The present invention draws the tool that repairs a die, and as shown in Figure 1, comprise counterdie 1, patrix 2 and upper edge iron block 12, lower edge iron block 11, wedge slide block 5 is located in patrix 2, and drive block 3 is located on counterdie 1, and drive block 3 is for having the drive block of the two-sided slide guide on two relative inclined-planes.Patrix 2 moves down and drives wedge slide block 5 to move, and fits and slides between two inclined-planes that wedge slide block 5 is placed in drive block 3 with two inclined-planes.Upper edge iron block 12 is located at one end of wedge slide block 5, relative with the plate of wanted deburring, and counterdie edge iron block 11 is fixed on counterdie 1 by counterdie insert 10.Wedge slide block 5 is synchronized with the movement at drive edge iron block 12, acts on, cut off plate, realize trimming function with lower edge iron block 11.
As shown in Figure 2, two inclined-planes on drive block 3 are respectively and drive slide guide face 31 and inclined-plane, slide guide face 32, two, anti-side to be parallel to each other.The drive block 3 of two-sided slide guide, wedge slide block 5 is moved between two back skating faces be parallel to each other, when the driving force that wedge slide block 5 motion is subject to back skating face, side produces torque, the back skating face on its opposite produces reciprocal power, moment of torsion is eliminated, ensures slide block stable motion, thus ensure that trimming edge gap is stablized, avoid deburring burr, improve the deburring quality of plate.
On wedge slide block 5, the side relative with driving slide guide face 3 and slide guide face, anti-side 32 is respectively equipped with slide plate 4.Slide plate 4 is and the ganoid straight plate driving slide guide face 31 and slide guide face, anti-side 32 to fit respectively.Ensure that wedge slide block 5 can smooth and easy stable slip between the driving slide guide face 31 of drive block 3 and slide guide face, anti-side 32 in motion process.
The upper of wedge slide block 5 is also provided with the nitrogen spring 6 that can be stored backhaul driving force by compression, and position relative with nitrogen spring 6 on patrix 2 is provided with cushion block 7.When wedge slide block 5 moves, nitrogen spring 6 pushes up on cushion block 7 and is realized backhaul function by compression.Nitrogen spring 6 stores backhaul driving force at matched moulds stage pressurized, and be convenient to assist wedge slide block 12 to reset in the die sinking stage, wedge slide block 12, under the reverberation matrix method of nitrogen spring 6 and the drive of patrix, resets to initial position.
Slide plate 8 is provided with between wedge slide block 5 and patrix 2.Upper guide plate 8 is provided with spaced apart two pieces.In the present invention, slide plate 4 and upper slide plate 8 are the straight plate that high-abrasive material is made, and protection wedge slide block 5 is worn, and strengthen its service life, and guarantee can more smooth and easy without hindrance motion.
Specific works principle of the present invention: in the matched moulds stage, patrix 2 drives wedge slide block 5 and material pressing core 9 to move downward, when reaching certain impulse stroke, material pressing core 9 starts to push down plate, patrix 2 continues to move downward, material pressing core 9 is motionless, simultaneously by flexible member to the certain pressure of plate, meet the requirement of deburring power.When patrix 2 continue to move downward reach certain stroke time, guide plate on wedge slide block 5 starts to contact with back skating face, anti-side 32 with the driving back skating face 31 of drive block 3, the drive part that is subject to of slide block imports in the back skating face of driving, wedge slide block 5 is moved along the direction of the b of arrow shown in figure, wedge slide block 5 has componental movement along arrow c direction simultaneously, nitrogen spring 6 is made to be stored backhaul driving force by compression, patrix 2 continues to move downward, upper edge iron block 11 is under the drive of wedge slide block 5, act on lower edge iron block 12 and cut off plate 9, matched moulds on earth, completes and draws trimming function.In the die sinking stage, patrix 2 moves upward, wedge slide block 5 is under the reverberation matrix method of nitrogen spring 6 and the drive of patrix 2, start to move along the opposite direction of b, until wedge slide block 5 departs from the back skating face of drive block 3 completely, wedge slide block resets to initial position, continues to move with the opposite direction of patrix along arrow a, patrix reaches top dead-centre, completes a stroke.Take plate away, put into process part processing and enter stroke next time.
Can be known by the discussion of above operation principle: what have anti-twisting function draws the stamping die of automotive covering part repaiied wedge and use mechanism, and be through technological innovation and research and develop the invention achievement designed, this kind of structure working principle is simple, novel; The compact in design of each parts, rational in infrastructure and attractive in appearance, and do not increase die space, significantly, this diel and anti-twisting are drawn and are repaiied wedge structure, under the prerequisite not increasing mould tricks, can realize compound working procedure, one set of die realizes more operation content, greatly reduce mould development cost, improving stamping production efficiency, is the once great innovation of Press Tools for Automobiles structural design.
The present invention draws the tool that repairs a die by being provided with the drive block 3 with two two-sided slide guides in inclined-plane, overcome wedge drive produce moment of torsion, make that wedge slide block 5 is parallel stably to move, ensure that trimming edge gap is stablized, ensure stamped part quality; Drive being arranged in parallel of slide guide face 31 and anti-32 two inclined-planes, slide guide face, side, ensure wedge slide block 5 working motion smoothly, thus reduce side force further, reduce distortion; In addition slide plate 4 is set on wedge slide block 5, improves its wearability, strengthen the service life of wedge slide block 5, and guarantee is slided smoothly further; Wedge slide block 5 moves downward, and imports the drive block 3 of two-sided slide guide by drive part, makes wedge slide block 5 along driving direction easy motion, ensures that upper and lower mould trimming edge gap is stablized; Patrix 2 continues descending, and upper edge iron block 12 and lower edge iron block 11 act on, and cuts off plate, reaches goal of the invention; The present invention draws the tool operation principle that repairs a die simple, the compact in design of each parts, rational in infrastructure, do not increase die space, wedge slide block 5 steady and smooth ground motion simultaneously, avoid deburring burr, ensure plate product quality, improve the mold use life-span, is the once lifting of Press Tools for Automobiles design level.
Above by reference to the accompanying drawings to invention has been exemplary description; but the present invention is not limited to aforesaid way; as long as adopt method of the present invention is conceived and technical scheme is carried out the improvement of various unsubstantialities or directly apply to other occasion, all drop in protection scope of the present invention.
