Description

Technical Field

[0001] The utility model relates to the field of stamping and bending devices, in particular to an automatic stamping and bending device of mechanical design. Background Art

[0002] Stamping is a production technology that uses the power of conventional or special stamping equipment to directly subject sheet metal to deformation force in the die and deform it, thereby obtaining product parts of a certain shape, size and performance.

[0003] In the existing stamping and bending dies for stamping steel plates, workers are required to place thin steel plates cut to appropriate sizes between the stamping dies. After the stamping dies are closed to stamp the steel plates, workers generally need to manually remove the plates in the stamping dies before they can put new plates into the stamping dies.

[0004] With regard to the above-mentioned related technologies, when the existing stamping and bending equipment is performing stamping and bending work on the plate, it is necessary to manually lift up and take out the plate before the new plate can be placed in the stamping die. The process of removing the stamped plate in the die wastes a lot of time, which seriously reduces the automation level of the stamping and bending equipment and affects the working efficiency of the stamping and bending equipment. In summary, the existing stamping and bending equipment requires manual removal of the stamped plate, which affects the working efficiency of the stamping and bending equipment. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a mechanically designed automated stamping and bending device to solve the technical problem that the existing stamping and bending equipment requires manual removal of the stamped plates.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a mechanically designed automated stamping and bending device, comprising an upper mold and a lower mold, the top surface of the lower mold being rotatably connected to at least one push rod, the rotating shaft of the push rod being close to the edge of the lower mold, the bottom surface of the upper mold being provided with a slider groove facing the end of the push rod away from its rotating shaft, a slider being slidably connected in the slider groove, a slider spring being connected between the top end of the slider and the inner wall of the slider groove, a slot for accommodating the push rod being provided at the bottom end of the slider, two blocking blocks being oppositely connected to the bottom end of the slot, and the end of the push rod will slide out of the slot after the upper mold is reset.

[0007] By adopting the above technical solution, a push rod structure is rotatably arranged on the surface of the lower mold, so that the stamped sheet is automatically discharged during the process of opening the mold, which effectively improves the working efficiency of the sheet stamping and bending equipment and reduces the labor intensity of the staff.

[0008] The utility model is further configured that a plurality of top column grooves are arranged at intervals in the lower mold, each of the top column grooves is slidably connected with a top column, and a top column spring is arranged between the bottom end of the top column and the inner wall of the top column groove.

[0009] By adopting the above technical solution, the ejector in the ejector groove is used to lift the plate when the upper mold is separated from the lower mold, thereby avoiding the situation where the plate is stuck on the lower mold and cannot be removed smoothly.

[0010] The utility model is further configured such that when the upper mold and the lower mold are closed, the ejector post is completely retracted into the ejector post groove.

[0011] By adopting the above technical solution, it is prevented that the ejector pin squeezes the plate and deforms the plate when the upper mold and the lower mold are closed.

[0012] The utility model is further configured such that the width of the clamping slot is greater than the width of the push rod, and the height of the clamping slot is greater than the thickness of the push rod.

[0013] By adopting the above technical solution, the push rod can be smoothly inserted into the slot.

[0014] The utility model is further configured such that when the upper mold and the lower mold are closed, a gap for accommodating a card block is left between the bottom end of the push rod and the lower mold.

[0015] By adopting the above technical solution, the push rod is inserted into the slot when the upper mold and the lower mold are closed.

[0016] The utility model is further configured that bearing platforms are fixedly connected to both sides of the lower mold, and a bearing platform groove for accommodating the bearing platform is provided at the bottom of the upper mold in the direction toward the lower mold.

[0017] By adopting the above technical solution, the supporting platform is used to support the plate required for stamping and bending.

[0018] The utility model is further configured that the lower mold is provided with a slide on one side close to the push rod rotating shaft.

[0019] By adopting the above technical solution, the landslide can play a certain guiding role on the sliding plate.

[0020] In summary, the utility model mainly has the following beneficial effects:

[0021] 1. The utility model arranges a push rod structure by rotating on the surface of the lower mold, and utilizes the sliding block in the upper mold to clamp the front end of the push rod when the mold is closed. After the stamping and bending work of the plate is completed, the sliding block brings up the push rod during the rising process of the upper mold, and the push rod rotates with the rotating shaft at one end of itself as the axis, lifts up the plate stamped on the surface of the lower mold, and provides an inclined sliding track for the plate, so that the plate can slide along the push rod. When the upper mold rises to the right position, the push rod is separated from the bottom end of the slide block and rotated and reset by its own gravity, so that the stamped plate is automatically discharged during the opening process of the mold, which effectively improves the working efficiency of the plate stamping and bending equipment and reduces the labor intensity of the staff.

[0022] 2. The utility model arranges a top column structure on the lower mold at intervals. When the upper and lower molds are closed, the top column retracts into the lower mold, and the spring at the bottom of the top column is compressed. When the upper and lower molds are separated, the top column can lift the plate to prevent the plate from being stuck on the lower mold due to bending and unable to be lifted up smoothly by the push rod.

The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0029] The following describes an embodiment of the utility model based on its overall structure.

[0030] Embodiment 1

[0031] A mechanically designed automated stamping and bending device, such as Figure 1-4As shown, it includes an upper mold 1 and a lower mold 2. The top surface of the lower mold 2 is rotatably connected to at least one push rod 4. Specifically, two push rods 4 are provided. The two push rods 4 can form a stable landslide for the plate after stamping and bending to slide down. The rotating shaft of the push rod 4 is close to the edge of the lower mold 2. The bottom surface of the upper mold 1 is provided with a slider groove 5 at the end facing the push rod 4 away from its rotating shaft. A slider 7 is slidably connected in the slider groove 5. A slider spring 6 is connected between the top of the slider 7 and the inner wall of the slider groove 5. A slot 8 for accommodating the push rod 4 is provided at the bottom end of the slider 7. Two clamping blocks 9 are oppositely connected to the bottom end of the slot 8. After the upper mold 1 is reset, the end of the push rod 4 will slide out of the slot 8.

[0032] See also Figure 1-2 The width of the slot 8 is greater than the width of the push rod 4, and the height of the slot 8 is greater than the thickness of the push rod 4, so that the push rod 4 can be smoothly inserted into the slot 8. When the upper mold 1 and the lower mold 2 are closed, a gap for accommodating the card block 9 is left between the bottom end of the push rod 4 and the lower mold 2, so that the push rod 4 is inserted into the slot 8 when the upper mold 1 and the lower mold 2 are closed. Specifically, the card block 9 is made of rubber, and the spacing between the two card blocks 9 connected oppositely at the bottom end of the slider 7 is smaller than the width of the push rod 4. When the slider 7 moves downward, the card block 9 contacts the push rod 4 and deforms until the card block 9 moves downward to the bottom of the push rod 4. After the card block 9 is reset, the push rod 4 is smoothly connected to the slot 8.

[0033] See also Figure 1-3 A bearing platform 13 is fixedly connected to both sides of the lower mold 2, and a bearing platform groove 14 for accommodating the bearing platform 13 is arranged at the bottom of the upper mold 1 towards the lower mold 2. When the upper mold 1 and the lower mold 2 are closed, the bearing platform groove 14 is used to accommodate the bearing platform 13, and the bearing platform 13 is used to carry the plate required for stamping and bending. A slide 15 is arranged on the side of the lower mold 2 close to the rotating shaft of the push rod 4. The slide 15 can play a certain guiding role for the sliding plate, so that it can slide down smoothly, which is convenient for collecting the stamped plate.

[0034] Embodiment 2

An ejector column spring 11 is arranged between the bottom end of the ejector column 12 and the inner wall of the ejector column groove 10. The ejector column 12 in the ejector column groove 10 is used to lift the plate when the upper mold 1 and the lower mold 2 are separated, so that the plate can be lifted more easily, avoiding the situation that the plate is stuck on the lower mold 2 and cannot be removed smoothly. When the upper mold 1 and the lower mold 2 are closed, the ejector column 12 is completely retracted into the ejector column groove 10, avoiding the ejector column 12 from squeezing the plate and deforming the plate when the upper mold 1 and the lower mold 2 are closed.

[0036] The working principle of the utility model is as follows: the plate to be stamped and bent is placed on the supporting platform 13, the upper mold 1 is pushed by the hydraulic rod to move toward the lower mold 2, the upper mold 1 and the lower mold 2 perform stamping and bending on the plate, when the upper mold 1 and the lower mold 2 are close to each other, the block 9 at the bottom of the slider 7 contacts the push rod 4 and deforms, as the slider 7 continues to move toward the lower mold 2, the slider spring 6 is compressed, and at the same time, when the lower end of the slider 7 contacts the lower mold 2, the block 9 is deformed and restored, at this time the push rod 4 is stuck in the slot 8, and as the upper mold 1 continues to move downward, the slider 7 gradually retracts to the slider The upper die 1 is moved upwards and the push rod 4 is lifted up, and the inclined track formed by the push rod 4 allows the plate to slide smoothly. When the upper die 1 is reset, the end of the push rod 4 leaves the card slot 8, and then the push rod 4 is rotated and reset by its own gravity.
