Detailed Description
The invention is described in detail below with reference to the attached drawing figures:
the invention provides an automatic die upward-looking punching method, which is realized by fully considering process planning when designing a punching process scheme, not only ensuring that the punching process scheme can meet the molding requirement of a side wall product, but also providing an effective and reasonable design space for a side wall upward-looking punching die of a front windshield side wall of a side wall. Through the automatic die upward-looking punching method technology, the design intention of increasing holes on the side wall of the front windshield of the side wall outer plate is realized, the requirement of punching tolerance can be ensured, and the most important is that the additional investment cost is not required.
The technical scheme of the invention is as follows: the side wall position of a front windshield of an outer side plate of a side wall has a negative angle under an automobile coordinate system, so that the conventional wedge structure for punching the side wall of the front windshield cannot be realized, and the aim of punching is fulfilled by a three-action flowering wedge upward-looking punching process. The process characteristics of the method determine that the product stamping process needs to be completed in multiple working procedures: a first step of drawing; a second step of trimming; a third procedure, namely flanging by using a wedge; fourthly, trimming by using a wedge; fifthly, flanging by using the wedge; and a sixth procedure, namely, three-action flowering wedge upward-looking punching.
When designing the stamping process scheme, the reasonability of process planning needs to be paid attention to, and particularly, the design space of an automatic die and the convenience of taking and delivering workpieces need to be fully considered in the three-action flowering wedge upward-looking punching process. A working component of a three-action flower-forming wedge upward-looking punching component of an upward-looking punching die comprises an upper die wedge driving assembly 1, an upper die wedge driving assembly 2, a lower die driving wedge assembly 3, a lower die flower-forming wedge assembly 4 and a lower die upward-looking punching wedge assembly 5.
The three-action flowering wedge upward-looking punching process fully considers the upward-looking punching wedge working direction and the flowering wedge working direction during the punching process design.
Referring to fig. 1 and 2, since the aperture of the upward-looking hole of the side wall of the front windshield of the product is small, the working direction of the upward-looking punching wedge is necessarily required to be basically vertical to the side wall of the product, and the maximum punching angle cannot exceed 3 degrees; the upward-looking punching wedge needs to be driven to work on the flowering wedge, and also needs to have a condition that the flowering wedge cannot interfere with a product during a return stroke, so that the product cannot have a negative angle in the working direction of the flowering wedge; the working directions of the two wedges are key factors for realizing the three-action flowering wedge upward-looking punching structure and are also difficult points of the punching process design. During the structural design of the die, five main components, namely an upper die wedge driving assembly 1, an upper die wedge driving assembly 2, a lower die driving wedge assembly 3, a lower die blooming wedge assembly 4 and a lower die upward-looking punching wedge assembly 5, are used for embodying a punching process scheme and realizing a three-action blooming wedge upward-looking punching process.
When the die works, the upper die wedge driving assembly 1 and the upper die wedge driving assembly 2 move downwards, the upper die wedge driving assembly 1 drives the lower die flowering wedge assembly 4 to move downwards along the working direction of the flowering wedge until the lower die flowering wedge assembly 4 moves to a product punching working position; meanwhile, the upper die wedge driving assembly 2 drives the lower die driving wedge assembly 3 to move downwards until the lower die driving wedge assembly 3 is contacted with the lower die upward-looking punching wedge assembly 5; the upper die wedge driving assembly 2 continues to drive the lower die driving wedge assembly 3 to move downwards, at the moment, the lower die driving wedge assembly 3 drives the lower die upward-looking punching wedge assembly 5 to start working along the upward-looking punching wedge working direction until the lower die upward-looking punching wedge assembly 5 and the lower die blooming wedge assembly 4 complete punching together, and the side wall front windshield side wall upward-looking punching is completed.
After the three-action flowering wedge upward-looking punching is completed, the upper die wedge driving assembly 1 and the upper die wedge driving assembly 2 move upwards, at the moment, the lower die flowering wedge assembly 4 is still, the lower die driving wedge assembly 3 starts to move in a return stroke, the lower die upward-looking punching wedge assembly 5 starts to move in the opposite direction along the upward-looking punching wedge work along with the return stroke of the lower die driving wedge assembly 3, until the lower die driving wedge assembly 3 and the lower die upward-looking punching wedge assembly 5 are completely separated, and the lower die upward-looking punching wedge assembly 5 finishes the return stroke work; the upper die wedge driving assembly 1 and the upper die wedge driving assembly 2 move upwards continuously, the lower die flowering wedge assembly 4 moves in the opposite direction of the working direction of the flowering wedge, the lower die driving wedge assembly 3 returns continuously until the upper die wedge driving assembly 1 and the upper die wedge driving assembly 2 are completely separated from the lower die flowering wedge assembly 4 and the lower die driving wedge assembly 3, the three-action flowering wedge upward-looking punching structure returns to the position completely, and the one-time three-action flowering wedge upward-looking punching working process is completed.
Referring to fig. 1, a schematic diagram of the position of the side wall upward-looking hole of the front windshield of the side wall outer plate is shown, and the position shown in the diagram relates to the product modeling which needs the three-action flower-opening inclined wedge upward-looking punching structure.
Referring to fig. 2, a schematic diagram of a three-action flower wedge elevation punching process scheme shows the side wall punching position of the front windshield of the side wall outer plate, the working direction of the flower wedge and the working direction of the elevation punching wedge.
Referring to fig. 3, a schematic diagram of a three-action cam drive mechanism for bottom-up punching is shown for upper cam drive assembly a1, upper cam drive assembly B2, lower cam drive assembly 3, lower cam drive assembly 4, and lower cam drive assembly 5.
Referring to FIG. 4, upper die cam drive assembly A1 is a schematic illustrating an upper die cam drive assembly A1 configuration.
Referring to FIG. 5, upper die cam drive assembly B2 is a schematic illustrating an upper die cam drive assembly B2 configuration.
Referring to FIG. 6, lower die drive cam assembly 3 is a schematic diagram illustrating the construction of lower die drive cam assembly 3.
Referring to fig. 7, the lower die flowering ramp assembly 4 is a schematic drawing illustrating the lower die flowering ramp assembly 4 configuration.
Referring to fig. 8, a lower die bottom view punch wedge assembly 5 is shown schematically illustrating the lower die bottom view punch wedge assembly 5 configuration.
Referring to fig. 9, a sectional view of a three-action flower wedge bottom punch structure is shown showing a distributor, a punch, a die insert, a scrap chute hole and a scrap pit. The waste materials punched by the three-action flowering wedge upward-looking punching structure cannot be automatically removed in a gravity mode, and the direction of the waste materials needs to be changed through the intervention of the distributor, so that the waste materials slide out of the waste material sliding holes in the die inserts and fall into a waste material pit, and the purpose of smoothly removing the waste materials is achieved.
The process planning must be fully considered when designing the stamping process scheme, so that the stamping process scheme is ensured to meet the molding requirement of the side wall product, and an effective and reasonable design space is provided for the side wall upward-looking punching die of the front windshield of the side wall. Through the upward-looking punching technology of the automatic die, the design intention of increasing holes in the side wall outer plate front windshield side wall is realized, the requirement of punching tolerance can be guaranteed, and the most important purpose is that the additional investment cost is not required.
Referring to fig. 3, 4, 5, 6, 7, 8 and 9, when the mold is in operation, upper mold cam driving assembly a1 and upper mold cam driving assembly B2 move downward, and upper mold cam driving assembly a1 drives lower mold flowering cam assembly 4 downward to move along the flowering cam working direction until lower mold flowering cam assembly 4 moves to the product punching working position;
meanwhile, the upper die wedge driving assembly B2 drives the lower die driving wedge assembly 3 to move downwards until the lower die driving wedge assembly 3 is contacted with the lower die downward-looking punching wedge assembly 5;
