Description

Technical Field

[0001] The present application relates to the field of mold technology, and in particular to a mechanical auxiliary feeding mechanism. Background Art

[0002] Molds are common equipment used in industry to make molded products. They use external forces to make the blank into a workpiece with a specific shape and size.

[0003] The continuous die is one of the common dies. It generally includes an upper die and a lower die. The lower die is installed on the ground, and the upper die is placed above the lower die. The strip-shaped stamping raw material is placed between the upper and lower dies. In one stamping stroke, multiple stamping processes are completed simultaneously on the strip-shaped stamping raw material through several different stations on the upper and lower dies.

[0004] After each stamping of the mold is completed, the upper mold and the lower mold are separated, the lower mold lifts up the strip stamping raw material, and moves the strip stamping raw material along the processing sequence direction, so as to facilitate the effect of continuously processing the strip stamping raw material.

[0005] There is a strip stamping raw material after processing, refer to Figure 1 The processed strip-shaped stamping raw material 3 includes a workpiece 31 that has been processed and a waste material 32, and the workpiece 31 and the waste material 32 are integrally formed. When the processed workpiece 31 is separated from the strip-shaped stamping raw material 3, it is necessary to separate the processed workpiece 31 from the strip-shaped stamping raw material 3 in a certain order, and then separate the waste material 32 from the strip-shaped stamping raw material 3.

[0006] With respect to the above-mentioned related technologies, the inventor believes that when the processed workpieces and the waste materials are separated from the strip stamping raw materials in the order of first separating the processed workpieces from the strip stamping raw materials and then separating the waste materials from the strip stamping raw materials, the processed workpieces and the waste materials are easily mixed together, and the staff need to spend time to separate the processed workpieces from the waste materials, thereby having the defect of increasing the labor intensity of the staff. Utility Model Content

[0007] In order to reduce the possibility of mixing the processed workpiece and the waste material when separating the processed workpiece and the waste material from the strip-shaped stamping raw material, the present application provides a mechanical auxiliary feeding mechanism.

[0008] The mechanical auxiliary feeding mechanism provided in this application adopts the following technical solution:

[0009] A mechanical auxiliary feeding mechanism comprises an upper die, a lower die and a strip of stamping raw material, wherein the lower die is placed on the ground, the upper die is placed above the lower die, the strip of stamping raw material is placed between the upper die and the lower die, a stamping block is arranged at the bottom of the upper die, a waste trough is arranged at the top of the lower die near the discharge end of the lower die, the stamping block and the waste trough are plug-fitted, an auxiliary component is arranged at the top of the lower die near the waste trough, the auxiliary component comprises a supporting block arranged at the top of the lower die and a flipping part arranged at a side of the supporting block near the waste trough, the flipping part and the supporting block are rotatably matched, and the flipping part supports the strip of stamping raw material.

[0010] By adopting the above technical solution, when the strip-shaped stamping raw material moves above the lower die, the supporting block and the flipping part cooperate with each other to provide auxiliary support for the strip-shaped stamping raw material. Thus, when the strip-shaped stamping raw material moves along the processing sequence direction, the possibility of the end of the strip-shaped stamping raw material entering the waste trough under its own gravity is reduced, thereby improving the reliability of the movement of the strip-shaped stamping raw material. When it is necessary to separate the processed workpiece and the waste from the strip-shaped stamping raw material, the waste is placed above the waste trough, and the waste is stamped and sheared by the punching block to disconnect the processed workpiece and the waste, collect the processed workpiece, and disconnect the waste from the strip-shaped stamping raw material. The punching block pushes the flipping part to rotate through the waste, releases the limit of the flipping part on the waste, and causes the waste to fall from the waste trough. After the waste falls, the flipping part is reset to provide auxiliary support for the subsequent strip-shaped stamping raw material. The processed workpiece and the waste are diverted, reducing the possibility of the processed workpiece and the waste being mixed together, thereby reducing the work intensity of the staff.

[0011] Optionally, a support groove is provided on one side of the support block close to the waste groove, and the support groove passes through the top and bottom of the support block. The flipping part includes an auxiliary block placed inside the support groove, an auxiliary rod rotatably passing through the auxiliary block, and a reset member placed on the inner wall of the support groove for resetting the auxiliary block to an initial position. An auxiliary strip is provided on the bottom of one side of the auxiliary block close to the strip-shaped stamping raw material. When the auxiliary block is in the initial position, the auxiliary strip provides auxiliary support for the strip-shaped stamping raw material. The length direction of the auxiliary rod is consistent with the length direction of the lower mold, and both ends of the auxiliary rod are rotatably passed through adjacent inner walls of the support groove.

[0012] By adopting the above technical solution, the auxiliary rod rotates to penetrate the auxiliary block, and the auxiliary rod penetrates the inner wall of the support groove, thereby facilitating the auxiliary block to rotate around the auxiliary rod. During the movement of the strip-shaped stamping raw material, the auxiliary strip on the auxiliary block guides and supports the strip-shaped stamping raw material, thereby reducing the possibility that the end of the strip-shaped stamping raw material enters the waste trough under the action of its own gravity. When the stamping block stamps and shears the waste, the stamping block squeezes the auxiliary block through the waste, and the auxiliary block rotates around the auxiliary rod, thereby allowing the waste to enter the waste trough. After the waste falls into the waste trough, the auxiliary block is reset to the initial position under the action of the reset member, thereby facilitating the auxiliary support of the subsequent strip-shaped stamping raw material.

[0013] Optionally, a reset hole is opened on the inner wall of the support groove on a side away from the strip-shaped stamping raw material, and a cap is provided at a position of the reset hole away from the strip-shaped stamping raw material. The reset member includes a reset rod and a reset spring arranged inside the reset hole, and one end of the reset spring away from the reset rod abuts against the cap, and one end of the reset rod away from the reset spring abuts against the side wall of the auxiliary block.

[0014] By adopting the above technical solution, one end of the reset spring contacts the cap, and the other end of the reset spring contacts the reset rod. When the punching block passes through the waste material to flip the auxiliary block, the auxiliary block squeezes the reset spring through the auxiliary rod. After the waste material falls into the waste material slot, the reset spring pushes the auxiliary block to reset through the reset rod, thereby facilitating the auxiliary support of the subsequent strip-shaped stamping raw materials.

[0015] Optionally, a limit ring is provided on the inner wall of the reset hole near the auxiliary block, and a limit disk is provided on one end of the reset rod near the reset spring, and the diameter of the limit disk is greater than the inner diameter of the limit ring.

[0016] By adopting the above technical solution, the reset spring and the limit plate are in conflict, and the diameter of the limit plate is larger than the inner diameter of the limit ring. When the reset spring pushes the reset rod to move through the limit plate, the limit ring limits the limit plate, thereby reducing the possibility of the reset rod escaping from the reset hole.

[0017] Optionally, the end of the reset rod away from the reset spring gradually becomes smaller in a direction from close to the reset spring to away from the reset spring.

[0018] By adopting the above technical solution, since the end of the reset rod away from the reset spring gradually becomes smaller in the direction from close to the reset spring to away from the reset spring, the reset rod and the auxiliary block have a smaller contact surface. During the rotation of the auxiliary block, the smaller contact surface between the reset rod and the auxiliary block reduces the contact resistance of the auxiliary block and improves the convenience of rotation of the auxiliary block.

[0019] Optionally, a positioning block is provided on a side of the inner wall of the support groove away from the strip-shaped stamping raw material, and when the positioning block abuts against the auxiliary block, the reset rod abuts against the auxiliary block.

[0020] By adopting the above technical solution, during the rotation of the auxiliary block, the auxiliary block is limited by the positioning block, thereby reducing the possibility that the auxiliary block rotates too much, making it difficult for the reset rod to push the auxiliary block to reset.

[0021] Optionally, a support bar is horizontally arranged at a bottom position on one side of the support block close to the strip-shaped stamping raw material.

[0022] By adopting the above technical solution, a support bar is arranged at the bottom of one side of the support block close to the strip stamping raw material. During the movement of the strip stamping raw material, the support bar guides and supports the strip stamping raw material, so that the strip stamping raw material is placed above the auxiliary bar.

[0023] Optionally, a push rod is vertically arranged at the bottom of the upper mold, and when the upper mold and the lower mold are closed, the bottom end of the push rod pushes the auxiliary block to rotate.

[0024] By adopting the above technical solution, when the upper die and the lower die are closed, the lower pressure rod at the bottom of the upper die pushes the auxiliary block to rotate. Therefore, when the punching block punches and shears the waste, the possibility of the waste being unable to push the auxiliary block to rotate due to its own deformation is reduced, and the possibility of the waste falling into the waste trough is further increased.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. When the strip-shaped stamping raw material moves above the lower die, the supporting block and the flipping part cooperate with each other to provide auxiliary support for the strip-shaped stamping raw material. Therefore, when the strip-shaped stamping raw material moves along the processing sequence direction, the possibility of the end of the strip-shaped stamping raw material entering the waste trough under its own gravity is reduced, thereby improving the reliability of the movement of the strip-shaped stamping raw material. When it is necessary to separate the processed workpiece and the waste from the strip-shaped stamping raw material, the waste is placed above the waste trough, and the waste is stamped and sheared by the punching block to disconnect the processed workpiece and the waste, collect the processed workpiece, and disconnect the waste from the strip-shaped stamping raw material. The punching block pushes the flipping part to rotate through the waste, releases the limit of the flipping part on the waste, and causes the waste to fall from the waste trough. After the waste falls, the flipping part is reset to provide auxiliary support for the subsequent strip-shaped stamping raw material. The processed workpiece and the waste are diverted, which reduces the possibility of the processed workpiece and the waste being mixed together, thereby reducing the work intensity of the staff.

[0027] 2. The auxiliary rod rotates to penetrate the auxiliary block, and the auxiliary rod penetrates the inner wall of the support groove, so that the auxiliary block can rotate around the auxiliary rod. During the movement of the strip-shaped stamping raw material, the auxiliary strip on the auxiliary block guides and supports the strip-shaped stamping raw material, thereby reducing the possibility that the end of the strip-shaped stamping raw material enters the waste trough under its own gravity. When the stamping block stamps and shears the waste, the stamping block squeezes the auxiliary block through the waste, and the auxiliary block rotates around the auxiliary rod, so that the waste falls into the waste trough. After the waste falls into the waste trough, the auxiliary block is reset to the initial position under the action of the reset member, so as to facilitate the auxiliary support of the subsequent strip-shaped stamping raw material.

When the upper mold 1 and the lower mold 2 are closed, the lower pressure rod 12 pushes the auxiliary block 421 to rotate clockwise around the auxiliary rod 422, so as to release the auxiliary strip 4211 from limiting the waste 32, so that the waste 32 falls into the waste trough 21. The finished workpiece 31 and the waste material 32 are separated when they are disconnected from the strip-shaped stamping raw material 3, which reduces the possibility of mixing the finished workpiece 31 and the waste material 32. When the upper mold 1 and the lower mold 2 are separated, the reset spring 4232 pushes the auxiliary block 421 to reset through the reset rod 4231, so that the auxiliary strip 4211 can assist in supporting the strip-shaped stamping raw material 3 again.
