Referring to fig. 1, the negative angle forming mechanism of the present embodiment is composed of a conventional upper die holder 1 and a conventional lower die holder 2, a female die 21 is disposed at a central position of a top of the lower die holder 2, protrusions 211 are disposed on left and right edges of a top surface of the female die 21, so as to recess a middle portion of the top surface of the female die 21, a male die 11 opposite to the female die 21 is disposed at a central position of a bottom of the upper die holder 1, and the male die 11 and the female die 21 are opposite to each other to punch and form the blank 5 in fig.
Since the negative angle forming mechanism of this embodiment is a two-mold die, the structures of the left and right sides are substantially the same, and there is only a slight difference in position, but the working process and principle are basically the same, and for simplifying the whole text, only the right side structure of the negative angle forming mechanism will be described below, and the left side structure of the negative angle forming mechanism can be referred to.
In order to synchronously form a negative angle during stamping of the blank 5, a horizontal lifting plate 3 is arranged on the right side of the female die 21 in the embodiment, the bottom of the lifting plate 3 is fixed on the lower die holder 2 through a first cylinder 31, wherein the first cylinder 31 is vertically arranged and locked on the top surface of the lower die holder 2 through threads, the end part of a piston of the first cylinder 31 is fixed on the bottom of the lifting plate 3 through a bolt, and the lifting plate 3 is driven by the first cylinder 31 to move up and down.
The top of the material lifting plate 3 is provided with a hinge block 32 on a side close to the die 21, a strip-shaped groove (not shown) is formed in the middle of the hinge block 32, and a lower clamping block 33 is placed in the strip-shaped groove in a state of being inclined toward the die 21 (i.e., a state shown by the lower clamping block in fig. 1) and is hinged to the strip-shaped groove by a rotation shaft 321. The bottom of the lower clamping block 33 protrudes laterally away from the die 21 to form a handle 34, the handle 34 is also in an inclined state and forms an angle of 90 ° with the lower clamping block 33, so that by pressing the handle 34 downward, the lower clamping block 33 can be rotated around the rotating shaft 321 to be rotated from the inclined state to the vertical state (i.e., the state shown by the lower clamping block in fig. 3), thereby realizing the lifting action of the lower clamping block 33. When the lower clamping block 33 rotates to the vertical state, the side wall of the lower clamping block is just in the same straight line with the side wall of the female die 21. Further, the top of the lower grip block 33 is a horizontal plane 331 in an inclined state, and when the lower grip block 33 rotates to become a vertical state, the horizontal plane 331 becomes an inclined state.
In order to enable the lower clamping block 33 to rotate and lift in the process of pressing down the upper die holder 1, a horizontal stripper plate 4 is arranged on the right side of the male die 11, the top of the stripper plate 4 is fixed on the upper die holder 1 through a second cylinder 41, the second cylinder 41 is vertically placed and locked on the bottom surface of the upper die holder 1 through threads, the end part of a piston of the second cylinder 41 is fixed to the top of the stripper plate 4 through a bolt, and the stripper plate 4 is driven by the second cylinder 41 to move up and down.
An upper clamping block 42 is fixedly arranged on one side of the bottom of the stripper plate 4 close to the male die 11, an inclined surface 421 inclined towards the direction close to the male die 11 is arranged at the bottom of the upper clamping block 42, and when the lower clamping block 33 is lifted to be in a vertical state, the inclined surface 421 is parallel to the rotated horizontal surface 331, so that the blank 5 is clamped between the upper clamping block and the lower clamping block. In order to lift the lower clamping block 33, the opposite ejection columns 43 are further fixed at the bottom of the stripper plate 4, the opposite ejection columns 43 are arranged right above the handle 34 to align with the handle 34, and the bottom of the opposite ejection columns 43 is lower than the bottom of the upper clamping block 42, so that during the process of pressing down the upper die base 1, the bottom of the opposite ejection columns 43 firstly presses the handle 34, so that the lower clamping block 33 is lifted to press the blank 5 originally placed on the horizontal plane 331 onto the inclined plane 421 of the upper clamping block 42, and clamping of the blank 5 is realized. In order to ensure that the blank 5 is not easy to slide when the blank 5 is clamped, the horizontal surface 331 is provided with teeth 332, and the inclined surface 421 is correspondingly provided with concave positions (not shown) for the teeth 332 to be embedded into, so as to ensure that the blank 5 is not easy to slide by the occlusion effect of the teeth 332 when the blank 5 is clamped.
When the negative angle molding of the blank 5 is performed, the operation of the negative angle molding mechanism of the present embodiment is as follows:
fig. 1 shows an initial mold opening state of the negative angle forming mechanism, in which the first cylinder 31 lifts the material lifting plate 3 until the top surface of the lower clamping block 33 is higher than the top protrusion 211 of the female mold 21, so that the space between the two lower clamping blocks 33 is higher than the female mold 21, which provides a space for the manipulator to feed the material, and the manipulator can feed the blank 5 shown in fig. 2 onto the horizontal surface 331 of the top surface of the lower clamping block 33 through the space, and at this time, the top surface of the lower clamping block 33 is kept horizontal because the lower clamping block 33 is not lifted yet, and the blank 5 can be flatly placed thereon.
After the feeding is completed, the upper die base 1 is pressed downwards, see the intermediate state of the negative angle forming mechanism in fig. 3, the ejection column 43 is firstly pressed to the handle 34 in the pressing process, so that the lower clamping block 33 is lifted to be in the vertical state, and the lower clamping block 33 presses the blank 5 on the horizontal plane 331 to the inclined plane 421 of the upper clamping block 42 after being lifted, so that the blank 5 is changed from the state in fig. 2 to the state in fig. 4.
After that, as shown in fig. 3, the upper die holder 1 continues to press down, the first cylinder 31 and the second cylinder 41 start to bear force, but the driving force of the second cylinder 41 is greater than that of the first cylinder 31, so that the first cylinder 31 starts to sink first, and the material lifting plate 3 is driven to sink.
The material lifting plate 3 sinks to the top surface of the lower die holder 2 and then is knocked to be dead, the top end of the lower material clamping block 33 is just flush with the protrusion 211 of the female die 21 at the moment, then the upper die holder 1 continues to press downwards to enable the second cylinder 41 to increase the stress, the material removing plate 4 moves upwards relative to the male die 11, the male die 11 extends out between the two upper material clamping blocks 42, the blank 5 is pressed downwards to the concave part embedded in the middle of the top surface of the female die 21, the die closing of the negative angle forming mechanism is completed at the moment, and the negative angle forming mechanism is in a die closing state shown in fig. 5. In the closed state, because the left and right edges of the top surface of the female die 21 have the protrusions 211, when the male die 11 presses the blank 5 to the concave part in the middle of the top surface of the female die 21, the blank 5 is shaped to change from the state shown in fig. 4 to the state shown in fig. 6, thereby completing the positive bending forming of the negative angle 51.
The negative angle forming mechanism of this embodiment bends the negative angle forming process of product through the rotation of lower clamp piece 33, by traditional slider side direction, becomes for positive bending to this reduces the required mould space of traditional slider side direction bending by a wide margin, thereby reduces mould material cost.
