Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology, specifically a flap wheel shaping device. Background Technology

[0002] When making a flap wheel with a movable handle using production equipment, the grinding disc is in a moving state and cannot be rotated into a neat circle. Therefore, manual intervention is required: first, use a soft belt or rope to rotate back and forth around the outer ring of the flap wheel to make its outer ring form a relatively regular circle (as shown in Figure 1). Finally, put on a sleeve to complete the final shaping for subsequent processing.

[0003] However, this process has the problem of being inconvenient to operate: when using a soft strap or rope, you need to first pinch both ends with your hands and bring them close together, and then switch to using one hand to pinch and operate. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a flap wheel shaping device that can be operated with one hand.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A flap wheel shaping device, comprising:

[0007] The body has a ring body, in which a working area is enclosed. The ring body has a break, and two handles are connected to the two ends of the break. The ring body can switch between a first state and a second state, in which the working area is larger than the working area in the second state.

[0008] A wear-resistant belt, which is fixed to the inner ring of the ring body;

[0009] In the first state, the ring body forms a break and there is a gap between the two handles; in the second state, the two ends of the ring body contact each other and form a complete circle, and the two ends of the wear-resistant belt are spliced ​​together, and the two handles contact each other.

[0010] In the above-mentioned flap wheel shaping device, the main body is made of plastic material.

[0011] In the above-mentioned flap wheel shaping device, the ring body is elastic.

[0012] In the above-mentioned flap wheel shaping device, the wear-resistant belt is made of steel belt.

[0013] In the above-mentioned flap wheel shaping device, a receiving groove is provided along the inner ring of the ring body, and the steel strip is fixed in the receiving groove.

[0014] In the above-mentioned flap wheel shaping device, the handle has a wave-shaped gripping part.

[0015] In the above-mentioned flap wheel shaping device, magnetic blocks are fixed on the side of the two handles that are close to each other, and the magnetic blocks on the two handles repel each other.

[0016] In the above-mentioned flap wheel shaping device, both the upper and lower ends of the inner ring of the ring body have inclined guide surfaces.

[0017] Compared with the prior art, this application has the following advantages:

[0018] There is no need to use both hands to hold the ends of the soft strap or rope separately. You can control the state switching of the ring by holding the two handles with one hand. The shaping action can be completed with one hand. After switching to the second state, the handles are in contact, and you can hold it with one hand to maintain the shape. This greatly simplifies the operation process, reduces the intensity of manual labor, and improves work efficiency. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0029] like Figures 2 to 5 As shown, a louver wheel 100 shaping device includes: a body 2 and a wear-resistant belt 3. The body 2 has a ring 21, with a working area 211 enclosed in the middle of the ring 21. The ring 21 has a break 212, and two handles 22 are connected to both ends of the break 212. The ring 21 can switch between a first state and a second state. The working area 211 in the first state is larger than the working area 211 in the second state. The wear-resistant belt 3 is fixed to the inner ring of the ring 21. In the first state, the ring 21 forms the break 212, and there is a gap between the two handles 22. In the second state, the two ends of the ring 21 contact each other and form a complete circle, and the two ends of the wear-resistant belt 3 are spliced ​​together, and the two handles 22 contact each other.

[0030] In this application, when in use, the device is first adjusted to the first state: at this time, the ring 21 is in a non-closed state due to the presence of the break 212, the two handles 22 are kept apart, and the working area 211 is in a larger size, which makes it easy to fit the working area 211 of the inner ring of the ring 21 onto the flap wheel 100 to be shaped. After the flap wheel 100 is placed in the working area 211, the operator holds the two handles 22 with one hand and applies force to switch the ring 21 from the first state to the second state: the two ends of the ring 21 gradually approach and contact each other to form a complete circle; at the same time, the two ends of the wear-resistant belt 3 fixed to the inner ring of the ring 21 are also spliced ​​together and tightly fit the outer ring of the flap wheel 100. With the help of the structural tension of the ring 21 and the wrapping force of the wear-resistant belt 3, the body 2 is then rotated back and forth to shape the flap wheel 100 into a regular circle.

[0031] There is no need to use both hands to hold the ends of the soft strap or rope separately. You can control the state switching of the ring body 21 by holding the two handles 22 with one hand. The shaping action can be completed with one hand. After switching to the second state, the handles 22 are in contact, and you can hold it with one hand to maintain the shaping. This greatly simplifies the operation process, reduces the intensity of manual labor, and improves work efficiency.

[0032] Specifically, the main body 2 is made of plastic material.

[0033] Specifically, the ring 21 is elastic. In the second state, the applied external force can be released, thereby allowing it to automatically return to the first state.

[0034] Specifically, the wear-resistant belt 3 is made of steel. Steel belts have good wear resistance, which increases their service life.

[0035] Specifically, a receiving groove is provided along the inner ring of the ring body 21, and the steel strip is fixed in the receiving groove.

[0036] Specifically, the handle 22 has a wave-shaped grip portion 221.

[0037] The ergonomic wave design distributes hand pressure, making it more comfortable to hold.

[0038] Specifically, magnetic blocks 23 are fixed on the sides of the two handles 22 that are close to each other, and the magnetic blocks 23 on the two handles 22 repel each other.

[0039] When the operator completes the shaping operation of the flap wheel 100 and releases the grip on the two handles 22, the two handles 22 can be automatically pushed to separate to both sides due to the thrust generated by the mutual repulsion of the magnetic blocks 23, so that the ring body 21 can quickly switch from the second state (closed circle) back to the first state (break 212 state).

[0040] Furthermore, the presence of two repulsive magnetic blocks 23 ensures that the two handles 22 remain at a preset distance, preventing the distance between them from decreasing over time, which would shrink the working area 211 and make it difficult to fit onto the flap wheel 100. The direction of repulsion between the magnetic blocks 23 is the same as the elastic return direction of the ring 21.

[0041] Specifically, the inner ring of the ring 21 has inclined guide surfaces 213 at both the upper and lower ends.

[0042] When the unshaped flap wheel 100 is placed into the working area 211 of the ring body 21, the inclined guide surface 213 plays a guiding role. The edge of the flap wheel 100 does not need to be precisely aligned with the inner ring entrance of the ring body 21. It only needs to be roughly close to it to slide into the interior of the ring body 21 along the inclined surface.

[0043] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationship and movement of the components in a specific posture, as shown in the attached figure. If the specific posture changes, the directional indication will also change accordingly.

[0044] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Meanwhile, the word "and / or" throughout the text means including three solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0045] All of the above components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0046] The specific embodiments described herein are merely illustrative examples of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from this utility model or exceeding the scope defined by the appended claims.
