Description

Technical Field

[0001] This utility model relates to the technical field of pneumatic shearing equipment in shearing devices, specifically a pneumatic shearing mechanism that facilitates material unloading. Background Technology

[0002] In existing technologies, pneumatic shearing mechanisms achieve shearing of workpieces through pneumatic means. The workpieces typically sheared in existing technologies include metal materials such as steel wire, copper wire, aluminum wire, and cables, as well as non-metallic materials such as cardboard, rubber strips, plastic sheets, and plastic strips. Most pneumatic shearing mechanisms have relatively simple structural designs, typically featuring a single shearing blade with a shearing groove, or a double shearing blade design to complete the shearing. However, for some industrial shearing equipment, a design with shearing blades and shearing grooves is more common and the structural design is more rational.

[0003] For example, the technical solution disclosed in Publication No. CN112453282A, entitled "A Shearing Mechanism," includes a support base, a fixed blade, a shearing arm, a movable blade, and a hydraulic cylinder. The fixed blade is fixedly mounted on the support base, the shearing arm is rotatably mounted on the support base, the movable blade is fixedly mounted at one end of the shearing arm, the cylinder body of the hydraulic cylinder is rotatably connected to the support base, and the output end of the hydraulic cylinder is rotatably connected to the other end of the shearing arm. In this invention, the hydraulic cylinder drives the movable blade to shear the stirrups via the shearing arm. The overall structure is simple and compact, the transmission process is safe and reliable, the manufacturing and maintenance costs are low, and the hydraulic cylinder has a fast extension and retraction speed, resulting in high processing efficiency when shearing stirrups.

[0004] For example, the "Automatic Cutting Mechanism" disclosed in Publication No. CN102836935A includes a cutting cylinder that drives a cutting plate to move, and a cutting blade is provided on one side of the cutting plate. This automatic cutting mechanism can independently complete the cutting action during coil manufacturing, making coil manufacturing more convenient and saving considerable time for the production of the next coil. Because this action can complete the cutting of four wires at once, the winding time is shortened, achieving a time-saving and labor-saving effect.

[0005] The above-mentioned technical solutions all have good structural design and good shearing effect, especially the ability to save labor or have high processing efficiency. However, the shearing device in the above-mentioned technical solutions usually does not involve the unloading of the workpiece after shearing. In the existing technology, the machine usually needs to be stopped to collect the workpiece after shearing, or the sheared workpiece is placed very randomly, and manual collection of the workpiece is required afterward. In practice, it is very troublesome and wasteful of manpower and resources. The workpiece cannot be recycled well and quickly after shearing.

[0006] In addition, existing technologies typically require sheared workpieces of a certain length as specified by the manufacturer. For example, some steel wires and copper wires require shearing to a certain length. However, existing technologies cannot achieve shearing of workpieces of a fixed length, nor can they combine the shearing of workpieces of a fixed length with the blanking process. Even if a fixed-length shearing mechanism and a subsequent blanking mechanism are set up separately, they are just two different mechanisms and cannot achieve a linkage design between the two. This increases costs and makes subsequent use more difficult, which is not worthwhile.

[0007] Therefore, in order to solve the above problems, it is necessary to develop a pneumatic shearing mechanism with a reasonable structure that can effectively improve work efficiency and quality and facilitate material feeding. Utility Model Content

[0008] The purpose of this invention is to address the shortcomings of existing technologies by providing a pneumatic shearing mechanism that facilitates material feeding; the technical solution is as follows:

[0009] A pneumatic shearing mechanism for easy material unloading includes two vertically placed fixed vertical plates on both sides, a horizontally arranged fixed horizontal plate installed at the upper end of the two fixed vertical plates, and a horizontal base plate installed between the bottom left sides of the two fixed vertical plates. The middle and right sides are both blank areas without plates. A shearing groove is correspondingly provided on the horizontal base plate, and a pneumatic device is installed at the upper end of the fixed horizontal plate. The main shaft of the pneumatic device passes downward through the fixed horizontal plate, and a shearing blade is installed at the shaft end. The position of the shearing blade corresponds to the position of the shearing groove.

[0010] Both fixed vertical plates are equipped with horizontally arranged flip motors at the lower right end. The motor shaft of the flip motor extends between the two fixed vertical plates, and several evenly spaced flip plates are installed on the motor shaft. The size of the flip plate is adapted to the size of the blank area. When the flip plate rotates with the motor shaft, it is embedded into the blank area.

[0011] Furthermore, the motor shaft has four evenly spaced flip plates arranged in a cross shape.

[0012] Furthermore, the flipping motor is configured as a stepper servo motor, and the angle of each flip is set to 90°.

[0013] Furthermore, the height of the flip plate is adapted to the height of the fixed vertical plate, and the length of the corresponding blank area is greater than the height of the fixed vertical plate.

[0014] Furthermore, the shearing groove on the transverse base plate is located at the right end, and the position of the shearing groove is close to the end of the flip plate.

[0015] Furthermore, when the flip plate flips with the motor shaft, when one flip plate is horizontally embedded into the blank area, the other flip plate is vertically placed on the right side of the two fixed vertical plates, while the other two flip plates are located on the outside.

[0016] The workpiece to be cut enters from the left side of the two fixed vertical plates. The workpiece stops after touching the vertically placed fixed vertical plate, so that the workpiece is placed on the flip plate of the horizontal base plate and the blank area respectively.

[0017] Furthermore, a receiving frame is provided below the blank area. After the workpiece is cut by the shearing blade, the flipping motor rotates counterclockwise, causing the flipping plate to rotate counterclockwise, so that the workpiece cut on the flipping plate falls into the receiving frame below.

[0018] Furthermore, there are two pneumatic devices on the fixed horizontal plate; the strokes of the two pneumatic devices are the same.

[0019] Beneficial effects: This utility model has the following beneficial effects:

[0020] 1) This device can perform fixed-length cutting of workpieces. After the workpiece enters the device, feeding can be stopped as long as the workpiece touches the vertical flip plate. After that, the length of the cut workpiece is fixed, thus achieving fixed-length cutting of workpieces.

[0021] 2) After the workpiece is cut, the unloading of the workpiece is very convenient. After the workpiece is cut, the flipping motor drives the flipping plate to flip accordingly, so that the workpiece will follow the flipping and the cut workpiece will fall into the receiving box below. The structure is clever and reasonable.

[0022] 3) In this device, a flipping plate is installed corresponding to a flipping motor, which drives the flipping plate to flip. First, the flipping plate can limit the feeding length of the workpiece to achieve fixed-length cutting. Second, the flipping plate can be used to unload the workpiece after cutting, achieving two goals at once.

[0023] 4) This device is ingeniously designed with a horizontal base plate and a blank area. A shearing groove can be set on the horizontal base plate, and a flipping plate can be placed in the blank area. This allows the workpiece to be sheared through the shearing groove on the horizontal base plate and placed on the flipping plate after shearing. The structure is reasonably designed.

[0024] 5) A receiving frame is also installed below the blank area in this device. After the workpiece is cut, it falls into the receiving frame as the flipping plate flips accordingly, thus realizing the unloading of the workpiece. The structure is reasonably designed.

[0025] 6) In this device, the flipping motor is set as a stepper motor structure, and the flipping plate is set with four cross-shaped sections, which can achieve both material blocking and material feeding purposes, and can realize stepping flipping. The structure is very reasonable. Attached Figure Description

[0032] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. These embodiments are implemented under the premise of the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0033] like Figure 1 , Figure 4 and Figure 5 As shown, a pneumatic shearing mechanism for easy material unloading includes two vertically placed fixed vertical plates 1, a horizontally arranged fixed horizontal plate 2 installed at the upper end of the two fixed vertical plates 1, and a horizontal base plate 3 installed between the bottom left sides of the two fixed vertical plates 1. The middle area and the right side area are both set as blank areas 4 without plates. A shearing groove 5 is correspondingly provided on the horizontal base plate 3, and a pneumatic device 6 is installed at the upper end of the fixed horizontal plate 2. The main shaft of the pneumatic device 6 passes downward through the fixed horizontal plate 2 and a shearing blade 7 is installed at the shaft end. The position of the shearing blade 7 corresponds to the position of the shearing groove 5.

[0034] Two fixed vertical plates 1 are each equipped with a horizontally arranged flipping motor 8 at the lower right end. The motor shaft 9 of the flipping motor 8 extends between the two fixed vertical plates 1. Several evenly spaced flipping plates 10 are installed on the motor shaft 9. The size of the flipping plate 10 is adapted to the size of the blank area 4. When the flipping plate 10 rotates with the motor shaft 9, it is embedded into the blank area 4.

[0035] The motor shaft 9 has four evenly spaced flip plates 10, which are arranged in a cross shape. The technical solution of this device is to achieve the flipping of the flip plates 10, and it is necessary to ensure that when one flip plate 10 is in a vertical position, another flip plate 10 is exactly in the horizontal blank area 4. One is placed vertically and the other needs to be placed horizontally. Therefore, setting four flip plates 10 is the most reasonable and can better cooperate to complete the shearing and feeding work.

[0036] The flip motor 8 is set as a stepper servo motor, and the flip angle of the flip motor 8 is set to 90° each time. The setting of the flip motor 8 in this device is very important. Setting it as a stepper motor is the most suitable. Since there are four flip plates 10, setting the flip angle of each flip to 90° can just achieve the effect that one flip plate 10 is located in the blank area 4 and one flip plate 10 is placed vertically.

[0037] The height of the flip plate 10 is adapted to the height of the fixed vertical plate 1, and the length of the blank area 4 is set to be greater than the height of the fixed vertical plate 1. This device needs to reasonably set the height and size of the flip plate 10. First, the width of the flip plate 10 is adapted to the size between the two fixed vertical plates 1, so that it can be flipped between the two fixed vertical plates 1. In addition, it is necessary to ensure that the flip plate 10 can be placed vertically between the two fixed vertical plates 1, so the height setting needs to be adapted to the height of the fixed vertical plate 1. In addition, the length of the blank area 4 should be set to be larger than the length of the flip plate 10 so that the flip plate 10 can be located within the blank area 4.

[0038] The shearing groove 5 on the horizontal base plate 3 is located on the right side, and the position of the shearing groove 5 is close to the end of the flip plate 10. In this device, the position of the shearing groove 5 needs to be designed to correspond to the position of the flip plate 10 so that the workpiece 11 can be placed on the flip plate 10 well after shearing is completed.

[0039] like Figure 2 As shown, when the flip plate 10 flips with the motor shaft 9, when one flip plate 10 is horizontally embedded into the blank area 4, the other flip plate 10 is vertically placed on the right side of the two fixed vertical plates 1, while the other two flip plates 10 are located on the outside.

[0040] The workpiece 11 to be cut enters from the left side of the two fixed vertical plates 1. The workpiece 11 stops after touching the vertically placed fixed vertical plate 1, so that the workpiece 11 is placed on the flip plate 10 of the horizontal base plate 3 and the blank area 4 respectively.

[0041] like Figure 3 As shown, a receiving frame 12 is also provided below the blank area 4. After the workpiece 11 is cut by the shearing blade 7, the flipping motor 8 rotates counterclockwise, driving the flipping plate 10 to rotate counterclockwise, so that the cut workpiece 11 on the flipping plate 10 falls into the receiving frame 12 below. There are two pneumatic devices 6 on the fixed horizontal plate 2. The strokes of the two pneumatic devices 6 are the same.

[0042] The overall working process of this device is as follows: Figure 1 , Figure 2 and Figure 3 As shown, the workpiece 11 cut by this device can be made of metal materials such as cables, steel wires, and aluminum wires, or it can be made of non-metallic materials such as cardboard, rubber sheets, plastic sheets, kraft paper, and corrugated paper. However, it cannot be a soft workpiece 11, such as ropes or strips of cotton cloth. The workpiece 11 must have a certain degree of toughness. Figure 1 As shown, in this device, the workpiece 11 first enters from the left side, and after entering, the workpiece 11 will touch the vertically placed flip plate 10 on the right side. The flip plate 10 has a limiting function. At this time, the length from the right end of the workpiece 11 to the cutting groove is fixed, which can ensure that the cutting length is consistent and complete the purpose of equal length cutting. During the process of the workpiece 11 entering and touching the vertical flip plate 10, the position and size of the flip plate 10 are quite important. First, the flip plate 10 can be placed vertically on the right side, which can block the area between the two vertical plates. Then the entering workpiece 11 can directly touch the vertical flip plate 10, thereby stopping the feeding. The feeding length of the workpiece 11 is determined, and the length of the cut workpiece 11 is also fixed, so the cutting length of the workpiece 11 can be achieved.

[0043] At this time, the workpiece 11 is actually placed on the left horizontal base plate 3 and the right flip plate 10. The flip plate 10 is actually placed in the blank area 4. The setting of the horizontal base plate 3 and the blank area 4 in this device is quite ingenious and important. The horizontal base plate 3 on the left is used to place the workpiece 11 and can be used to set the shearing groove 5, while the right side needs to be set as the blank area 4. The blank area 4 is used to place the flip plate 10 and enable the flip plate 10 to rotate in the blank area 4. The vertical flip plate 10 needs to be located between the two vertical plates, and the horizontal flip plate 10 needs to be located in the blank area 4. The size of the blank area 4 needs to be set accordingly. In fact, the blank area 4 needs to be set to be longer than the length of the flip plate 10 so that the flip plate 10 can always follow the flip motor 8 to rotate, thereby realizing the shearing of the workpiece 11 and the unloading of the workpiece 11.

[0044] After the workpiece 11 is placed, the pneumatic device 6 on the fixed horizontal plate 2 drives the shearing blade 7 to move down and press into the shearing groove 5, thereby cutting the workpiece 11 and completing the shearing work. After the shearing work is completed, since the shearing groove 5 on the horizontal base plate 3 is located at the rightmost end, close to the flipping plate 10 in the blank area 4, the workpiece 11 is actually placed on the flipping plate 10 in the blank area 4 after being cut. At this time, it is only necessary to control the flipping plate 10 to rotate counterclockwise by the flipping motor 8. Figure 2 As shown, the flip plate 10 will cause the workpiece 11 to tilt accordingly, so that it falls into the receiving frame 12 below.

[0045] This device also requires a stepper motor mechanism for the flipping motor 8, which moves 90° with each flip. When the flipping motor 8 is activated, the sheared workpiece 11 falls into the receiving frame 12 below. Figure 3 As shown, the subsequent flip plate 10 will re-enter the blank area 4, and the other flip plate 10 will enter the right side of the two fixed vertical plates 1 and be placed vertically. After the workpiece 11 continues to enter, the next round of workpiece 11 cutting work will be carried out. It can complete the continuous cutting work and realize the overall material unloading process.

[0046] In the technical solution of this device, the structural arrangement of the flipping motor 8 and the flipping plate 10 is very important. The main purpose is to enable the flipping motor 8 to drive the flipping plate 10 to rotate accordingly, so that the workpiece 11 placed on the flipping plate 10 after shearing can be placed into the receiving frame 12 below through the flipping action to realize the overall unloading work, which makes unloading very convenient. In addition, the setting of the horizontal base plate 3 and the blank area 4 are also important. The horizontal base plate 3 is set on the left side of the two fixed vertical plates 1, which is used to connect the fixed vertical plates 1 on both sides and can be set with shearing grooves 5. The blank area 4 is mainly used to place the flipping plate 10. The flipping plate 10 can rotate in the blank area 4, and the flipping plate 10 is mainly used to place the incoming workpiece 11. In this way, the flipping unloading of the workpiece 11 can be realized. The overall structural arrangement is quite reasonable and ingenious.

All equivalent changes and modifications made in accordance with the scope of protection of this utility model patent application should be included within the scope of this utility model patent application.
