Description

Technical Field

[0001] The utility model relates to a demoulding tool with an adjustable diameter of a center hole of a baffle for axially extracting a winding part, belonging to the technical field of demoulding tooling. Background Art

[0002] A type of tubular composite material is formed by winding fiber cloth layer by layer onto a roll and then impregnating and curing it. After curing, the roll needs to be removed (also known as core pulling in the industry). Traditional removal tooling consists of a fixed frame, a connecting shaft, and a baffle with a center hole. The roll is placed on the connecting shaft and fixed, and the baffle is removable and fixed to the fixed frame. The inner diameter of the center hole of the baffle is slightly larger than the diameter of the roll. During use, the baffle around the center hole blocks the end face of the tubular composite material, and the roll is removed by forcefully pulling on the connecting shaft to complete the demolding.

[0003] Because different types of cylindrical composite materials have different circular holes, the diameter of the rolls varies during production, requiring the center hole of the baffle to be changed accordingly. However, the center hole diameter of the baffle in traditional tooling is fixed, so only by replacing the baffle with a center hole of the corresponding diameter can the requirement be met. This not only increases the workload but also reduces processing efficiency. Utility Model Content

[0004] The technical problem to be solved by the utility model is: how to meet the processing requirements of cylindrical composite materials with different apertures without replacing the baffle.

[0005] In view of the above problems, the technical solutions proposed by the present invention are:

[0006] A demolding tool with an adjustable center hole diameter for the axial extraction of wound parts comprises a frame, a connecting shaft, and a baffle with a center hole. The connecting shaft is fitted and axially fixed within the axial hole of the winding drum. The baffle includes a fixed plate with a large circular hole (I) in its center. A plurality of sliders are provided on the fixed plate outside the large circular hole (I), capable of extending into the large circular hole (I) and sliding centrifugally and centrifugally. The center hole is formed by the inner ends of the multiple sliders enclosing the large circular hole. The inner diameter of the center hole is larger than the diameter of the winding drum. When demolding begins, the front end of the connecting shaft extends forward through the center hole.

[0007] A plurality of guide slots for accommodating the slider body and guiding the sliding movement of the slider body are arranged on the fixing plate.

[0008] The guide chute is an arc-shaped chute that starts in the tangential direction but turns centripetally in the middle section, and the slider body is an arc-shaped slider that adapts to the arc of the guide chute.

[0009] The above-mentioned demolding tooling also includes a guide adjustment disk, the center of which has a large circular hole 2 with the same aperture as the large circular hole 1. On the guide adjustment disk outside the large circular hole 2, there are radially arranged waist-shaped sliding holes corresponding to the number of the slider body, and a fixed push pin is provided on the slider body. The guide adjustment disk is pressed against the slider body, and the push pin is located in the waist-shaped sliding hole. By rotating the guide adjustment disk, the slider body is made to slide centripetally or centrifugally in the guide slide groove through the push pin. At the same time, the slider body that slides centripetally or centrifugally causes the push pin to slide radially in the waist-shaped sliding hole.

[0010] The bottom width of the guide slot is greater than the slot opening width, and correspondingly, the bottom surface width of the slider body is greater than the top surface width, so that the slider body is confined in the guide slot of the fixed plate; the top end of the push column fixed on the slider body has a column handle with a diameter greater than the width of the waist-shaped sliding hole, so that the guide adjustment disk is confined to the fixed plate.

[0011] A push-and-turn handle for rotating the guide adjustment disk is provided on the guide adjustment disk.

[0012] The guide adjustment disk is a circular disk. A plurality of rolling bearings pressed against the outer peripheral surface of the guide adjustment disk are provided on a fixed plate on the outer peripheral surface of the guide adjustment disk to limit the center of the guide adjustment disk to the axis line of the large circular hole.

[0013] A threaded through hole is provided on the guide adjustment disk, and a positioning screw is arranged in the threaded through hole. Beneficial effects

[0014] 1. As the slider body can slide centrifugally and centrifugally, the diameter of the center hole can adapt to the change of the reel diameter. In this way, winding parts of various specifications can be removed without replacing the baffle, thereby significantly improving work efficiency and reducing labor intensity.

DETAILED DESCRIPTION

[0022] The present invention will be further described below with reference to the accompanying drawings:

[0023] like Figure 1 、 2 As shown in Figures 5 and 6, a demolding tool with an adjustable center hole diameter of a baffle plate 2 for axially extracting a wound article comprises a frame 1, a connecting shaft 3, and a baffle plate 2 having a center hole 200. The connecting shaft 3 is fitted and axially fixed in the axial center hole of the reel 4. The baffle plate 2 comprises a fixed plate 201 having a large circular hole 2011 in the center. A plurality of slider bodies 202 are provided on the fixed plate 201 outside the large circular hole 2011, capable of centripetal and centrifugal sliding within the range of the large circular hole 2011. The center hole 200 is formed by the inner ends of the plurality of slider bodies 202 enclosing within the range of the large circular hole. The inner diameter of the center hole 200 is slightly larger than the diameter of the reel 4. When demolding begins, the front end of the connecting shaft 3 extends forward through the center hole 200, and the wound article 5 is blocked by the baffle plate 2 on the outer periphery of the center hole 200. The front end of the connecting shaft 3 is pulled forward, so that the connecting shaft 3 is extracted together with the reel 4, thereby achieving demolding. Since the slider body 202 can slide centrifugally and centrifugally, the diameter of the center hole 200 can adapt to the changes in the diameter of the reel 4. In this way, winding parts of various specifications can be removed without replacing the baffle 2, thereby significantly improving work efficiency and reducing labor intensity.

[0024] like Figure 2 、 3 As shown, the fixed plate 201 is further provided with a plurality of guide slots 2012 that accommodate the slider body 202 and guide its sliding movement. The guide slots 2012 are arc-shaped slots that initially extend tangentially but then make a centripetal arc turn in the middle. The slider body 202 is an arc-shaped slider adapted to the arc shape of the guide slots 2012. During use, the slider body 202 slides along the guide slots in an oblique, centripetal, or centrifugal manner, rather than directly in a radial direction.

[0025] like Figure 2As shown in FIG. 4 , the baffle 2 further includes a guide adjustment disk 203 having a second large circular hole 2031 at its center having the same diameter as the first large circular hole 2011. Outside the second large circular hole 2031, the guide adjustment disk 203 has a number of waist-shaped sliding holes 2032 radially arranged thereon, corresponding to the number of the slider body 202. A push pin 204 is fixedly mounted on the slider body 202. The guide adjustment disk 203 is pressed against the slider body 202, and the push pin 204 is located within the waist-shaped sliding hole 2032. Rotating the guide adjustment disk 203 causes the push pin 204 to cause the slider body 202 to slide centrifugally or centrifugally within the guide slot 2012. Simultaneously, the centrifugal or centrifugal sliding of the slider body 202 causes the push pin 204 to slide radially within the waist-shaped sliding hole 2032. Thus, the size of the center hole 200 can be adjusted simply by rotating the guide adjustment disk 203.

[0026] The bottom width of the guide groove 2012 is greater than the slot width, and correspondingly, the bottom width of the slider body 202 is greater than the top width, so that the slider body 202 is restricted in the guide groove 2012 of the fixed plate 201; the top of the push column 204 fixedly set on the slider body 202 has a column handle 2041 with a diameter greater than the width of the waist-shaped sliding hole 2032, so that the guide adjustment disk 203 is restricted on the fixed plate 201, and then the baffle becomes an integral component that can adjust the size of the center hole 200.

[0027] A push handle 205 for rotating the guide adjustment disk 203 is provided on the guide adjustment disk 203, making the adjustment operation very simple.

[0028] The guide adjustment disk 203 is a circular disk. On the fixed plate 201 on the outer periphery of the guide adjustment disk 203, there are multiple rolling bearings 207 pressed against the outer periphery of the guide adjustment disk 203, which are used to limit the center of the guide adjustment disk 203 to the axis line of the large circular hole 2011.

[0029] A threaded through hole 2033 is provided on the guide adjustment disk 203 , a positioning screw 206 is provided in the threaded through hole 2033 , and a rotating handle is provided at the end of the positioning screw 206 .

[0030] The above embodiments are only used to more clearly describe the present invention and cannot be regarded as limiting the scope of protection covered by the present invention. Any modifications in equivalent forms should be regarded as falling within the scope of protection covered by the present invention.
