Below the side part and on the left side of the left raised stopper, the demolding support bar assembly on the right side is arranged below the right part of the stripping beam and on the right side of the right raised stopper; (2)、启动冲压模具的压力机,冲压模具的压力机活塞杆带动上模座上移,上模座开始带动着上模垂直向上运动,绑在两个吊环上的钢丝绳开始分别牵引相应左右两侧的脱模支撑棒组件向上移动,由于左侧钢丝绳施加给左侧脱模支撑棒组件的牵引力是沿着左侧钢丝绳的长度方向向上的,且左侧钢丝绳施加给左侧脱模支撑棒组件的牵引力作用点位于左侧脱模支撑棒组件和脱模横梁接触点(A点)的右侧,因此左侧钢丝绳的拉力对左侧脱模支撑棒组件的作用力相当于施加了一个相对于左侧脱模支撑棒组件和脱模横梁接触点(A点)向右转动的转矩,左侧脱模支撑棒组件的两个摩擦环筒在左侧钢丝绳的牵引下有向右转动的趋势,由于左侧脱模支撑棒组件会受到脱模横梁和左侧挡块的约束,所以左侧脱模支撑棒组件只能在左侧钢丝绳的牵引下带动着位于左侧脱模支撑棒组件上侧的脱模横梁的左侧部向上移动,同理,右侧脱模支撑棒组件在右侧钢丝绳的牵引下带动着位于右侧脱模支撑棒组件上侧的脱模横梁的右侧部向上移动,如此,在两个脱模支撑棒组件的承载作用下,脱模横梁随上模座一起向上移动,各根顶模立柱的顶端便会向上穿过相应各个脱模孔顶压嵌在下模中的冲压件,使冲压件缓慢向上顶起,如此进行脱模;(2) Start the press of the stamping die, the piston rod of the press of the stamping die drives the upper die base to move up, the upper die base starts to drive the upper die to move vertically upward, and the wire ropes tied to the two rings begin to pull the corresponding left and right respectively. The stripping support rod assemblies on both sides move upward, because the traction force applied by the left steel wire rope to the left stripping support rod assembly is upward along the length of the left steel wire rope, and the left steel wire rope is applied to the left stripping support rod. The traction force acting point of the assembly is located on the right side of the contact point (point A) between the left demoulding support rod assembly and the demoulding beam, so the pulling force of the left wire rope on the left demoulding support rod assembly is equivalent to exerting a relative force. Due to the torque of the left demoulding support rod assembly and the contact point (point A) of the demoulding beam rotating to the right, the two friction ring cylinders of the left demoulding support rod assembly turn to the right under the traction of the left steel wire rope. Since the left demoulding support rod assembly is constrained by the demoulding beam and the left stopper, the left demoulding support rod assembly can only drive the demoulding support located on the left side under the traction of the left wire rope. The left side of the stripping beam on the upper side of the rod assembly moves upwards. Similarly, the right stripping support rod assembly drives the right side of the stripping beam located on the upper side of the right stripping support rod assembly under the traction of the right wire rope. The side part moves upward, so that under the bearing of the two stripping support rod assemblies, the stripping beam moves up together with the upper die base, and the top of each top die column will push upward through the corresponding stripping holes. The stamping part embedded in the lower die makes the stamping part slowly lift up, so that the mold is demolded; (3)、随着两个脱模支撑棒组件带动脱模横梁向上运动到一定高度,左侧脱模支撑棒组件的两个摩擦环筒上侧面开始与左侧两块竖直挡板的下侧边左侧部接触,而此时,左侧钢丝绳施加给左侧脱模支撑棒组件的牵引力仍是沿着左侧钢丝绳的长度方向向上的,且左侧钢丝绳施加给左侧脱模支撑棒组件的牵引力作用点位于左侧脱模支撑棒组件和左侧两块竖直挡板的下侧边左侧部接触点(B点)的左侧,因此左侧钢丝绳的拉力对左侧脱模支撑棒组件的作用力相当于施加了一个相对于左侧脱模支撑棒组件和左侧两块竖直挡板的下侧边左侧部接触点(B点)向左转动的转矩,由于左侧两块竖直挡板的下侧边左侧部左高右低倾斜设置,则左侧脱模支撑棒组件的两个摩擦环筒在左侧钢丝绳的牵引下会沿着左侧两块竖直挡板的下侧边左侧部向左上转动,因为此时左侧脱模支撑棒组件的两个摩擦环筒依旧与脱模横梁的底面左侧部进行接触(C点),所以在左侧脱模支撑棒组件向左上转动的同时依旧会带着脱模横梁的左侧部向上移动,同理,右侧脱模支撑棒组件的两个摩擦环筒在右侧钢丝绳的牵引下会沿着右侧两块竖直挡板的下侧边右侧部向右上转动,因为此时右侧脱模支撑棒组件的两个摩擦环筒依旧与脱模横梁的底面右侧部进行接触,所以在右侧脱模支撑棒组件向右上转动的同时依旧会带着脱模横梁的右侧部向上移动,在两个脱模支撑棒组件的承载作用下,脱模横梁继续随上模座一起向上移动,继续进行脱模;(3) As the two stripping support rod assemblies drive the stripping beam upward to a certain height, the upper sides of the two friction ring cylinders of the left stripping support rod assembly begin to align with the lower sides of the two vertical baffles on the left. The left side of the side is in contact, and at this time, the traction force applied by the left wire rope to the left demoulding support rod assembly is still upward along the length of the left wire rope, and the left wire rope is applied to the left demoulding support rod. The traction force of the assembly is located on the left side of the contact point (point B) of the left side of the left side demoulding support rod assembly and the left side of the two vertical baffles, so the pulling force of the left steel wire rope will release the left side. The force of the support rod assembly is equivalent to applying a torque that rotates to the left relative to the contact point (point B) of the left side of the lower side of the left side demoulding support rod assembly and the left two vertical baffles, Since the left side of the lower side of the two vertical baffles on the left is inclined at a high left and a low right, the two friction rings of the left demoulding support rod assembly will be pulled along the left side by the left wire rope. The left side of the lower side of the vertical baffle plate is turned to the upper left, because the two friction ring cylinders of the left side stripping support rod assembly are still in contact with the left side of the bottom surface of the stripping beam (point C), so When the left demoulding support rod assembly rotates to the upper left, it will still move upward with the left part of the demoulding beam. Similarly, the two friction rings of the right demoulding support rod assembly will be pulled by the right wire rope. Rotate the right side along the lower side of the two vertical baffles on the right to the upper right, because at this time the two friction ring cylinders of the right stripping support rod assembly are still in contact with the right part of the bottom surface of the stripping beam. Therefore, when the right demoulding support rod assembly rotates upward to the right, it will still move upward with the right side of the demoulding beam. Under the load of the two demoulding supporting rod assemblies, the demoulding beam continues to move upwards with the upper die base. Move, continue demoulding; (4)、随着两个脱模支撑棒组件带动脱模横梁继续向上运动到一定高度,左侧脱模支撑棒组件的两个摩擦环筒在左侧钢丝绳的牵引下沿着左侧两块竖直挡板的下侧边左侧部继续向左上转动,当左侧脱模支撑棒组件运动到与左侧两块竖直挡板的下侧边左侧部接触点(D点)时,脱模横梁的底面左侧部与左侧脱模支撑棒组件分离,同理,脱模横梁的底面右侧部与右侧脱模支撑棒组件分离,如此,脱模横梁便会失去两个脱模支撑棒组件的支撑而下落,回到初始位置,此时,各根顶模立柱便将冲压件从下模中顶出,最终完成整个脱模过程;(4) As the two stripping support rod assemblies drive the stripping beam to continue to move upward to a certain height, the two friction ring cylinders of the left stripping support rod assembly move along the left two blocks under the traction of the left steel wire rope. The left side of the lower side of the vertical baffle continues to rotate to the upper left. When the left demoulding support rod assembly moves to the contact point (point D) with the left side of the lower side of the two left vertical baffles, The left part of the bottom surface of the stripping beam is separated from the left stripping support rod assembly. Similarly, the right part of the bottom surface of the stripping beam is separated from the right stripping support rod assembly. In this way, the stripping beam will lose two stripping rods. The die support rod assembly falls down and returns to the initial position. At this time, each top die column pushes the stamping part out of the lower die, and finally completes the entire demoulding process; (5)、在下次进行冲压加工之前只需要将两个脱模支撑棒组件放回初始位置,使两个脱模支撑棒组件对脱模横梁的底面左右两侧部分别进行支撑,重复上述步骤(1)-(4),便可再次实现如上所述的脱模过程。(5) Before the next stamping process, you only need to put the two stripping support rod assemblies back to the initial position, so that the two stripping support rod components support the left and right sides of the bottom surface of the stripping beam respectively, and repeat the above steps (1)-(4), the demoulding process as described above can be realized again.
