Description

Technical Field

[0001] The invention belongs to the field of steel plate stamping application equipment, and in particular relates to a steel plate stamping subsequent plate turning and stacking device. Background Art

[0002] Press forming refers to a processing method in which a press and a die are used to apply external force to plates, strips, tubes and profiles to cause them to undergo plastic deformation or separation, thereby obtaining a workpiece (stamping part) of the desired shape and size.

[0003] Among the existing automobile or motorcycle accessories, there are many that require circular stamping parts. In order to obtain the relevant circular stamping parts, people place the steel plate on a press and use the action of the press to continuously separate the circular stamping parts from the steel plate, thereby obtaining the required stamping parts.

[0004] The steel plates after being stamped cannot be used anymore because they contain a large number of round holes. Therefore, they are often treated as scrap steel. In order to ensure the cleanliness of the factory, after the steel plates are stamped, they are transported to an empty position through a roller conveyor rack. Then, the steel plates are flipped from the roller conveyor rack to the ground using the flipping mechanism set on the roller conveyor rack. After a certain number of them are piled up, they are bundled and packaged for sale.

[0005] Although the above method can complete the stacking of scrap steel plates to a certain extent, it is affected by gravity, the flap mechanism, etc., resulting in very irregular stacked scrap steel plates. In order to reduce costs as much as possible, the steel plates are generally stamped close to the edges during the stamping process, which may result in gaps at the ends of the steel plates. These gaps are easy to scratch and injure the staff due to the irregular stacking, which poses a certain safety hazard. If a frame is used for collection, there is a problem of affecting packaging. Although the use of a multi-degree-of-freedom manipulator can achieve precise stacking, the cost of use is high. Summary of the invention

DETAILED DESCRIPTION

[0030] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0032] Embodiment 1, as Figure 1 to Figure 11 As shown, the present embodiment aims to provide a palletizing device which can realize regular palletizing of steel plates after stamping and is simple to operate, and has low use cost and manufacturing cost. Therefore, in order to achieve the above-mentioned purpose, the steel plate stamping subsequent flipping palletizing device provided in the present embodiment comprises a roller conveyor frame 1 and a flipping mechanism 2 arranged on the roller conveyor frame 1 for flipping one side of the steel plate. The roller conveyor frame 1 is an existing equipment, so it is not described in detail in the present embodiment.

[0033] Considering that there are two reasons why the scrap steel plates fall irregularly from the flap mechanism 2, one is that the sliding speeds of the two ends of the scrap steel plates are inconsistent, resulting in a certain angle when the scrap steel plates fall, and the other is that the scrap steel plates are not restrained in the process of falling, resulting in an increasing change in their angles, thereby causing the scrap steel plates to be stacked unevenly. Therefore, in order to restrain the scrap steel plates to a certain extent, in this embodiment, a plate connecting mechanism 3 is provided on one side of the roller conveyor frame 1. The plate connecting mechanism 3 is provided for two purposes, one is to avoid the existence of a falling angle, and the other is to prevent the scrap steel plates from falling. The first is to ensure the inconvenience of the angle when falling. For this reason, the plate receiving mechanism 3 provided in this embodiment is arranged on the side of the overturning mechanism 2 that overturns the steel plate. The plate receiving mechanism 3 includes a frame 31 and a plate receiving frame 32 slidably arranged on the frame 31. In this embodiment, the frame 31 is a square frame, and the plate receiving frame 32 is a door-shaped frame as a whole. A slider is arranged at the bottom of the plate receiving frame 32, and a track matching the slider is arranged on the frame 31. At the same time, a sliding cylinder 33 is arranged on the frame 31 for pushing the plate receiving frame 32 to slide back and forth in the direction of the roller conveyor frame 1.

[0034] In order to achieve the purpose of receiving and dropping the plates, in the present embodiment, a 90-degree flip cylinder 34 is provided on the side of the plate receiving frame 32 facing the roller conveyor frame 1. The 90-degree flip cylinder 34 is a cylinder that can realize a 90-degree flip at the output end. Since it needs to be flipped downward, the 90-degree flip cylinder 34 is horizontally arranged, and the flipping end of the 90-degree flip cylinder 34 is connected to a plate receiving seat 35. The plate receiving seat 35 includes a vertical portion 351 connected to the flipping end of the 90-degree flip cylinder 34 and a horizontal portion 352 perpendicularly arranged to the vertical portion 351. The cross-section of the plate receiving seat 35 is L-shaped. In the present embodiment, the vertical portion 351 refers to the portion of the plate receiving seat 35 that is in a vertical state when the 90-degree flip cylinder 34 is in a non-working reset state, and the horizontal portion 352 is located on the side close to the roller conveyor frame 1.

[0035] It should be noted that the height of the plate receiving seat 35 is lower than the height setting of the flip mechanism 2. This is because the scrap steel plate will only slide down after the flip mechanism 2 is flipped up to a certain height, and the plate receiving seat 35 is mainly used to support the other end of the sliding scrap steel plate. For this reason, the height of the plate receiving seat 35 is lower than the height setting of the flip mechanism 2.

[0036] In order to provide a space for placing the scrap steel plate, the roller conveyor frame 1 and the plate receiving mechanism 3 are spaced apart. At the same time, in order to ensure the accuracy during the falling process, in this embodiment, a positioning column 4 is further arranged between the roller conveyor frame 1 and the plate receiving mechanism 3. At least three positioning columns 4 are arranged, and the positioning columns 4 are staggered. The three positioning columns 4 are distributed in a triangular shape, so that the consistency of the scrap steel plate falling can be ensured.

[0037] Through the above-mentioned arrangement, when the scrap steel plate is transported to the top of the flip mechanism 2 through the roller conveyor frame 1, the sliding cylinder 33 works to push the plate receiving seat 35 toward the roller conveyor frame 1, so that it is close to the roller conveyor frame 1, ensuring that the scrap steel plate can effectively resist the plate receiving seat 35, and then the flip mechanism 2 starts to work. During the flipping process of the flip mechanism 2, the scrap steel plate continues to tilt and fall. When its side moves to the plate receiving seat 35, the sliding cylinder 33 starts to slowly reset. At the same time, the 90-degree flip cylinder 34 starts to work. The scrap steel plate continues to fall and adjust its position under the tilting action of both sides. Until the hole of the scrap steel plate is above the positioning column 4, the flip mechanism 2 and the plate receiving seat 35 are both flipped 90 degrees to ensure that the scrap steel plate falls vertically to complete the stacking.

[0038] In order to ensure the slow control of the flap mechanism 2, in this embodiment, in addition to the cylinder used being a controllable forming cylinder, the structure of the flap mechanism 2 is also improved. Specifically, the flap mechanism 2 includes a flip shaft 21 rotatably arranged on one side of the roller conveyor frame 1 and a connecting plate 22 spaced apart on the flip shaft 21, and a flip rod 23 is arranged at one end of the connecting plate 22 away from the flip shaft 21. In addition to the part in the roller conveyor frame 1, the flip rod 23 also has a certain extension in the direction of the connecting plate mechanism 3 to ensure tilting. In this embodiment, a gear 25 is arranged on the flip shaft 21, and a driving cylinder 26 is arranged on the frame of the roller conveyor frame 1, and the power end of the driving cylinder 26 is connected to a rack, so as to reduce the rotation speed of the flip shaft 21 and ensure slow falling.

[0039] Considering that one side of the steel plate often has a notch in order to save raw materials, in order to prevent the overturning rod 23 from losing control due to the notch during the sliding process of the scrap steel plate, a overturning plate 24 is provided on the side of the overturning rod 23 away from the roller conveyor frame 1. The overturning plate 24, like the overturning shaft 21, covers all the overturning rods 23, so that, by using the arrangement of the overturning plate 24, there is no possibility of leakage even if there is a notch, thereby avoiding the possibility of leakage of the plate.

[0040] Considering that the scrap steel plate falls vertically, in order to avoid the scrap steel plate from generating a large noise, in this embodiment, a drop buffer mechanism is provided on the positioning column 4. The main purpose of the drop buffer mechanism is to reduce the speed of vertical falling. To this end, in this embodiment, the drop buffer mechanism includes a high-pressure tube cavity 41 arranged in the positioning column 4 and a buffer rod 43 arranged outside the positioning column 4. In this embodiment, in order to facilitate the placement of the buffer rod, the diameter of the positioning column 4 is as close as possible to the diameter of the punching hole of the scrap steel plate. A placement groove 42 for placing the buffer rod 43 is provided on the side wall of the positioning column. The high-pressure tube cavity 41 is provided in the positioning column 4. 1 is arranged along the axis of the positioning column 4, and a pressure regulating piston 44 is arranged in the high-pressure tube cavity 41. The pressure regulating piston 44 is arranged in the high-pressure tube cavity 41 for lifting and lowering. The pressure regulating piston 44 controls the change of the gas pressure in the high-pressure tube cavity 41 by lifting and lowering. In order to enable the pressure regulating piston 44 to effectively control the pressure of the gas in the high-pressure tube cavity 41, in this embodiment, the high-pressure tube cavity 41 is divided into three parts according to the upper and lower settings. The lowermost part is the regulating cavity, in which the pressure regulating piston 44 is mounted, and the uppermost part is the buffer cavity, whose diameter is at most one-third of the regulating cavity, and the middle part is the transition cavity, whose cross section is set in a trapezoidal shape. In this way, the up and down movement of the pressure regulating piston 44 can drive the entire high-pressure tube cavity 41 to achieve a large pressure change. The high-pressure tube cavity 41 is filled with nitrogen or an oil-gas mixture.

[0041] At the same time, a control hole 45 is also provided on the positioning column 4, and the control hole 45 is connected to the high-pressure tube cavity 41, and the control hole 45 and the high-pressure tube cavity 41 are set at a vertical angle, a buffer piston 46 is installed in the control hole 45, and the buffer piston 46 is provided with an air hole to ensure the gas flow in the chamber on the left and right of the buffer piston 46, and a buffer piston rod 47 is installed on the buffer piston 46, and the buffer piston rod 47 is extended out of the control hole 45, and the buffer piston 46 is used to push the buffer piston rod 47 to extend, and the end of the buffer piston rod 47 extending out of the control hole 45 is hinged to the buffer rod 43, in order to ensure that the force of the scrap steel plate can reset the buffer piston rod 47, an upper hinge seat 431 and a lower hinge seat 432 are arranged up and down on the buffer rod 43, wherein the lower hinge seat 432 and the buffer rod 43 are ball-connected, and the upper hinge seat 431 and the lower hinge as a whole are U-shaped hinge seats, just to adapt to the inclination of the buffer rod 43, and the lower hinge seat 432 and the buffer rod 43 are ball-connected. The buffer rod 43 is hinged to the buffer piston rod 47 through an upper hinge seat 431 and a lower hinge seat 432 respectively. The buffer rod 43 is set at an inclined angle under the action of the buffer piston rod 47 connected up and down.

[0042] In this way, the falling scrap steel plate falls on the buffer rod 43, squeezes the buffer rod 43, and causes the nitrogen or oil-gas mixture to enter the control hole 45, so as to change the angle of the buffer rod 43 and complete the falling. The function of the pressure regulating piston 44 is to reduce the pressure in the high-pressure tube cavity 41, so that the pressure in the control hole 45 is consistent with the pressure in the high-pressure tube cavity 41, so that the buffer piston rod 47 cannot automatically extend, which is convenient for the subsequent removal of the scrap steel plates from the positioning tube after bundling and packaging.

[0043] In order to realize the control of the pressure regulating piston 44, the pressure regulating piston 44 is hinged with a pressure regulating connecting rod 51, and a base 5 is provided at the bottom of the positioning column 4. An eccentric flywheel 52 axially connected to the pressure regulating connecting rod 51 is provided in the base 5, and a driving shaft 53 is provided on the eccentric flywheel 52. The driving shaft 53 extends out of the base 5, and a driving mechanism 6 for controlling the reciprocating rotation of the driving shaft 53 is provided on the base 5. In this embodiment, the driving mechanism 6 is also a structure in which a cylinder controls a rod connected to the driving shaft 53, thereby realizing the reciprocating motion of the pressure regulating piston 44.

[0044] In order to effectively achieve buffering, in this embodiment, the buffer rods 43 are evenly distributed in a ring shape on the side wall of the positioning column 4. Specifically, four buffer rods 43 are arranged on the same layer, and the angle between each buffer rod 43 is 90 degrees. At the same time, at least three groups of buffer rods 43 arranged up and down are arranged on the positioning column 4. In this way, the purpose of slowing down the falling speed is achieved by continuous buffering, thereby reducing noise. In this embodiment, in order to facilitate the bundling of scrap steel plates, a baffle 48 is arranged above the base 5, and the baffle 48 is mounted below the positioning column 4. In this way, the scrap steel rod falls on the baffle 48, which is convenient for subsequent bundling and also convenient for the installation of the cylinder in the driving mechanism.

[0045] Considering that both ends of the upper side of the buffer rod 43 need to be extended, when the scrap steel plate falls, it may get stuck on the top of the buffer rod 43 and affect the falling, so a guide round platform 7 is provided on the top of the positioning column 4. The guide round platform 7 covers the top of the uppermost buffer rod 43, thereby ensuring the accurate falling of the scrap steel plate.

[0046] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
