Description

Working method of universal die for aluminum plate stamping

Technical Field

The invention relates to the technical field of metal processing equipment, in particular to a working method of a universal die for punching an aluminum plate.

Background

The aluminum plate is an aluminum plate or an aluminum sheet in which the aluminum material having a thickness of 0.2mm to 500mm inclusive, a width of 200mm to 16m inclusive is called an aluminum plate or an aluminum sheet, the aluminum material having a thickness of 0.2mm or less is an aluminum material, and the aluminum material having a width of 200mm or less is a row material or a strip material (of course, with the progress of large-scale equipment, there are many aluminum plates having a maximum width of 600 mm). Aluminum sheets have found a great deal of use in the aerospace, automotive, machinery, marine and chemical industries because of their superior properties.

However, in the use process of the existing aluminum plate, different use environments need to be punched to manufacture different shapes, however, after the aluminum plate is processed, the aluminum plate is mostly in a planar shape, and the planar structure cannot meet the requirements under special environments.

Chinese patent application No.: CN 201810236849.7; the publication date is as follows: 2018.09.04 discloses an aluminum alloy furniture section bar production is with bending device of adjustable angle of bending, has the low inconvenient problem of adjusting of angle of bending precision to current bending device for sheet metal processing, now proposes following scheme, including sheet metal body, support frame and motor cabinet, the low side of support frame is close to both sides welding and has the square pipe that is parallel to each other, and the intraductal equal sliding connection of two square has flexible pipe, two the top of flexible pipe is fixed with primary shaft bearing and secondary shaft bearing through the bolt respectively, equal joint has four circular cone roller bearings in primary shaft bearing and the secondary shaft bearing. The invention can support the punched thin plate to continuously bend for a certain angle, thereby improving the controllability of the bending angle, and the second telescopic rod can rise along with the movement of the thin plate and can be always contacted with the thin plate to carry out secondary bending on the thin plate.

Chinese patent application No.: CN 201810648293.2; the publication date is as follows: 2018.11.16 discloses a curved aluminum plate and a processing method thereof, which solves the problem of high difficulty in processing the whole curved aluminum plate, and comprises a plurality of splicing units, wherein each splicing unit comprises a bracket and a plurality of aluminum plates, the side walls of the adjacent aluminum plates are mutually abutted, and the aluminum plates are spliced into the curved aluminum plate; the processing difficulty of the aluminum plate is reduced.

The working principle of the invention is as follows: when carrying out aluminum plate's towards type during operation, at first put into the inside in blowing chamber with aluminum plate level through the manual work, then start major axis cylinder 401 through controller 3 to start its output, slider and spout sliding connection, slider again with public mould 1 fixed connection, and then guaranteed the steadiness that public mould 1 operated.

After aluminum plate is put into the discharging cavity horizontally, long shaft cylinder 401 is started through controller 3, thereby through its output end and drive ejector pad 403 to shrink, because the one end of ejector pad 403 far away from long shaft cylinder 401 passes through connecting rod fixed connection with the one end of ejector pad 402, ejector pad 402 is again with bottom plate 400 sliding connection, therefore drive ejector pad 402 to slide to the one end far away from ejector pad 403 in the top of bottom plate 400, the gliding stability of ejector pad 402 can be ensured in the design of spacing groove, prevent its collapse etc., when needing to punch the surface of aluminum plate into different shapes or structures, start shift knob, controller 3 receives shift knob's signal after, start two-way lead screw slip table 21, thereby adjust the position of every group jacking subassembly 41 in female mold 2 inside, therefore make things convenient for aluminum plate to punch different surface shapes or structures.

When punching is carried out, the push plate 402 slides towards one end close to the roller 411, when the outer wall of the push plate 402 contacts with the outer wall of the roller 411, the roller 411 rotates under the action of a collision force, the roller 411 is simultaneously contracted by the first spring 413, when the roller 411 rotates, because the roller 411 is fixedly connected with the arc plate 415, the arc plate 415 is fixedly connected with the flange 414, because the flange 414 is fixedly connected with the insert rod 410, the top of the insert rod 410 is inserted and connected with the inside of the ejector rod 42, the insert rod 410 is inserted and connected with the sleeve block 412, the bottom of the sleeve block 412 and the top of the flange 414 respectively abut against two ends of the first spring 413, so that the insert rod 410 is driven to ascend and abut against the insertion hole at the bottom of the ejector rod 42, the insert rod 410 is driven to ascend, the aluminum plate is punched in cooperation with the pressing block 10 at the bottom of the male die 1, the guide strip 416 is slidably connected with the guide groove to prevent the insert rod 410 from, the top of the insert rod 410 is designed to be a wedge-shaped structure, and the cooperation of the insert block 417 and the insert hole facilitates the more stable abutting of the insert rod 410 against the bottom of the ejector rod 42 without slipping, thereby ensuring the stability of the ejector rod 42 during upward ejection, the push plate 402 is non-rigidly connected with the roller 411, and the roller 411 is designed to rotate, compared with the technical characteristics of the traditional die in which an air cylinder is directly used as a stamping driving source, the stamping process is slow, and the stamping process is gradual, when any adverse condition occurs in the aluminum plate stamping, the die is convenient to stop suddenly, large product loss is avoided, the stamping efficiency is improved, the product quality is improved, the enterprise loss is reduced, the stamping cost is further reduced, when the aluminum plate is stamped, the four guide rods 500 and the plurality of insert pins 501 are inserted and connected with the four guide holes and the plurality of insert holes, thereby facilitating the better die assembly of the male die 1 and the female die 2, meanwhile, the smooth operation of the aluminum plate stamping work is ensured.

When pushing up at ejector pin 42 and punching type to aluminum plate, two interior poles 420 receive the shrink effect of two second springs 423, slide in the inside slow speed of two loop bars 421, and then drive two connecting block slow speed and slide, because two connecting blocks all with ejector pin 42 fixed connection, therefore drive ejector pin 42 and produce a buffer force when pushing up, be favorable to guaranteeing aluminum plate's processingquality, prevent that the punching press is too big and damage aluminum plate, two locating pins 424 play the effect of direction simultaneously, steadiness when guaranteeing ejector pin 42 and pushing up, aluminum plate's punching type quality has further been ensured to two interior poles 420 of cooperation.

When the punching of aluminum plate ends, long axis cylinder 401 is started through controller 3 to drive male die 1 to rise, four guide bars 500 and a plurality of contact pin 501 slide upwards in four guide holes and a plurality of contact pin holes on female die 2, two depression bars 510 receive the conflict effect of two third springs 511 to female die 2 uplift upwards simultaneously, vacate the space for the shipment in blowing chamber, and finally, aluminum plate after punching is ejecting by a plurality of ejector pin 42 in the blowing chamber, for the workman takes out.
