Description

Technical Field

[0001] The invention relates to the technical field of film sleeve stripping, in particular to an isostatic film sleeve stripping device. Background Art

[0002] Silver-based electrical contact materials used in the low-voltage electrical appliance industry are typically formed through extrusion and isostatic pressing. For isostatic pressing, the powder is initially packed into a rubber sleeve before being placed in an isostatic cylinder for high-pressure forming. Due to variations in the properties and state of the powder, the formed spindle will adhere to the inner wall of the rubber sleeve to varying degrees, requiring the sleeve to be peeled off during discharge.

[0003] The current industry generally uses manual peeling and demoulding. However, in cases where the adhesion is relatively tight, manual peeling can easily damage the film sleeve. In minor cases, it can cause micropores and cracks in the film sleeve, causing oil leakage and material contamination during the next powder filling. At the same time, such manual operation increases employee labor intensity and reduces production efficiency. Summary of the Invention

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0026] The following combination Figures 1 to 4An isostatic film sleeve stripping device according to an embodiment of the present invention is described, which includes a frame 1, a bracket 2, a clamping mechanism 3, an air-filled stripping mechanism 4 and a sealing mechanism 5; the bracket 2 is arranged on the frame 1, the clamping mechanism 3 is arranged at one end of the bracket 2, and the sealing mechanism 5 is arranged at the other end of the bracket 2; the air-filled stripping mechanism 4 includes a sealing plug 41 and an air pipe 42 arranged in the sealing plug 41, the air pipe 42 connects the inner and outer sides of the sealing plug 41, and the outer side of the air pipe 42 is connected to an external control box; the sealing plug 41 is connected to the output end of the sealing mechanism 5, and under the drive of the sealing mechanism 5, the sealing plug 41 performs a linear sliding motion on the frame 1.

[0027] Specifically, in the specific operation of this embodiment, the workpiece wrapped by the film sleeve is placed on the bracket 2, the bottom of the mold sleeve is placed on the clamping mechanism 3, and the end of the film sleeve is facing the direction of the sealing plug 41. Then, the sealing mechanism 5 is driven to push the sealing plug 41 toward the film sleeve, so that the sealing plug 41 is close to the film sleeve. At the same time, the air pipe 42 is inserted from the outside of the sealing plug 41 and communicates with the inside of the film sleeve. As the sealing mechanism 5 is driven, the sealing plug 41 clamps the workpiece wrapped by the film sleeve between the inner wall of the bracket 2 and the sealing plug 41. After the film sleeve is sealed, the air pipe 42 is controlled by an external control box to fill the film sleeve with compressed air, and the pressure is maintained for 5 minutes to peel the film sleeve from the workpiece. Then, the sealing mechanism 5 is started to drive the sealing plug 41 away from the film sleeve, and the clamping mechanism 3 clamps the bottom of the film sleeve, and the workpiece is taken out of the film sleeve to complete the peeling process of the workpiece and the mold sleeve, thereby solving the problem of manual peeling, which is easy to cause micropores and cracks in the film sleeve, and even cause damage to the film sleeve, resulting in oil leakage and contamination of materials when the film sleeve is filled with powder next time.

[0028] Furthermore, it also includes a bracket swing mechanism 6, the upper end surface of the frame 1 is provided with a feeding hole, one end of the bracket 2 is hingedly connected to the frame 1, and the bracket swing mechanism 6 is arranged on the frame 1. Under the drive of the bracket swing mechanism 6, the bracket 2 rotates around the hinge axis hinged to the frame 1 and enters the interior of the frame 1 through the feeding hole.

[0029] Specifically, in this embodiment, one end of the bracket 2 is hingedly connected to the frame 1, so that the bracket 2 is rotatably connected to the frame 1. When the air-inflating stripping mechanism 4 fills the film sleeve with compressed air to complete the stripping, the sealing mechanism 5 controls the sealing plug 41 to leave the film sleeve. After the clamping mechanism 3 clamps the bottom of the film sleeve, the bracket swinging mechanism 6 is started to drive the bracket 2 to rotate and tilt downward from the discharge hole. Due to the action of gravity, the workpiece in the film sleeve will slide down along the bracket 2 to the inside of the frame 1, thereby realizing automatic unloading of the workpiece, reducing the labor intensity of workers and improving work efficiency.

[0030] Furthermore, the bracket swing mechanism 6 is a swing cylinder, which is arranged inside the frame 1. The bracket 2 is arranged at the upper end of the frame 1 and is hingedly connected to the frame 1. The piston rod of the swing cylinder is hingedly connected to the bracket 2.

[0031] Specifically, in this embodiment, the movement of the bracket 2 is driven by the swing cylinder. When the bracket 2 is in a horizontal state, the piston rod of the swing cylinder is extended, so that the bracket 2 is in a horizontal state. When the workpiece needs to be unloaded, the swing cylinder drives its piston rod to retract, so that the bracket 2 rotates around the hinge axis with the frame 1. As the angle of the bracket 2 changes, the swing cylinder rotates accordingly around the hinge axis with the frame 1, so that the bracket 2 completes the tilt, and the workpiece slides naturally due to gravity. The swing cylinder can not only drive the movement of the bracket 2, but also support the bottom of the bracket 2, to ensure the smooth movement of the bracket 2 and improve the stability of the overall structure.

[0032] Furthermore, a buffer platform 11 is provided inside the frame 1 , and the buffer platform 11 is provided with a sloped surface. The buffer platform 11 is arranged below the discharge hole.

[0033] Specifically, in this embodiment, after the workpiece and the film sleeve are peeled off, the bracket 2 is tilted, and the workpiece will slide down to the buffer table 11 due to gravity, and slide down along the slope of the buffer table 11 to the bottom of the frame 1, thereby protecting the workpiece and preventing the workpiece from falling directly to the bottom of the frame 1 and causing damage to the workpiece.

[0034] Furthermore, the frame 1 is provided with a protective cover mechanism 7, which includes a protective cover body 71 and a protective cover driving mechanism 72. The protective cover body 71 is arranged above the bracket 2, and one end of the protective cover body 71 is hingedly connected to the frame 1. Under the drive of the protective cover driving mechanism 72, the protective cover body 71 rotates to cover the bracket 2.

[0035] Specifically, in this embodiment, the protective cover mechanism 7 is used to protect the workpiece peeled off from the bracket 2. One end of the protective cover body 71 is hinged to the frame 1. When the workpiece needs to be placed, the protective cover driving mechanism 72 drives the protective cover body 71 to rotate and open. After the workpiece is placed, the protective cover driving mechanism 72 drives the protective cover body 71 to rotate and seal again. Then, the workpiece and the film sleeve are peeled off, etc., to protect the workpiece and the film sleeve. Accidents may occur during the peeling process of the film sleeve and the workpiece, causing harm to people.

[0036] Furthermore, the protective cover driving mechanism 72 is a protective cover cylinder, which is arranged on the frame 1 , and a piston rod of the protective cover cylinder is hingedly connected to the protective cover body 71 .

[0037] Specifically, in this embodiment, the protective cover cylinder is installed on the frame 1, one end of the protective cover body 71 is hingedly connected to the frame 1, and the piston rod of the protective cover cylinder is hingedly connected to the other end of the protective cover body 71. When the protective cover body 71 is in a closed state, the piston rod of the protective cover cylinder is in an extended state. When the protective cover body 71 needs to be opened, the protective cover cylinder drives the piston rod to retract, and pulls up the other end of the protective cover body 71 through the piston rod, so that the protective cover body 71 rotates around the hinge axis between it and the frame 1, thereby opening the protective cover body 71.

[0038] Furthermore, the sealing mechanism 5 is a sealing cylinder, which is arranged on the frame 1 and located on one side of the bracket 2, and the sealing plug 41 is arranged on the piston rod of the sealing cylinder.

[0039] Specifically, in this embodiment, after the workpiece covered with the film sleeve is placed on the bracket 2, the sealing cylinder is started, and the piston rod of the sealing cylinder moves with the sealing plug 41 to clamp the workpiece between the bracket 2 and the sealing plug 41. The workpiece can be fixed while the open end of the film sleeve is sealed by the sealing plug 41, so that the film sleeve is in a closed state, and compressed air is injected into the film sleeve through the air pipe 42 to peel the film sleeve off from the workpiece.

[0040] Furthermore, the clamping mechanism 3 is a finger cylinder, which is arranged at one end inside the bracket 2 .

[0041] Specifically, in this embodiment, the clamping mechanism 3 adopts a finger cylinder, which has the advantages of fast response speed, simple installation and convenient operation. When the workpiece and the film sleeve are peeled off, the workpiece and the film sleeve need to be separated and the film sleeve needs to be clamped. At this time, the finger cylinder is driven, and the pneumatic clamp of the finger cylinder will clamp the bottom of the film sleeve, thereby facilitating the workpiece to be pulled out.

[0042] Furthermore, the frame 1 is provided with four pulleys 12 .

[0043] Specifically, in this embodiment, a pulley 12 is provided at each of the four corners of the bottom surface of the frame 1. When the peeling device needs to be moved, the four pulleys 12 can be lowered to move the device. The pulley 12 is easy to move, which can reduce the labor intensity of transportation.
