Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of part processing, and in particular to a novel metal part protective sleeve. BACKGROUND

[0002] In the industry, metal parts usually need to go through the processes of processing, transportation and storage. In the processing process, the non-processing areas of the metal parts are easily damaged due to welding, knocking, high temperature, shot blasting, paint spraying and other process procedures. In the transportation and storage process, the metal parts are also easily damaged or scrapped due to physical collision, chemical contact and other problems. In particular, in the field of national defense and military industry, aerospace, etc., most metal parts have complex structures, high processing difficulty, high material price, high appearance and precision requirements, and even a small damage can cause the metal parts to be scrapped, resulting in great loss.

[0003] In the prior art, there are methods of using nylon pipe material, bar material and sheet material to make relatively simple protective tooling through cutting, turning, polishing and other processes. However, this method cannot process protective tooling with complex structures due to the shape and processing technology of nylon material. In addition, the hardness of nylon material is relatively high and lacks elasticity, which cannot effectively play a protective role, and the size of the product is difficult to control. There are also methods of using cast polyurethane material to process a mold that can effectively vent pressure according to the shape of the protective tooling and the characteristics of the liquid material casting process, to obtain a protective sleeve product with good quality. However, this method is affected by the filling method, pressure method and conventional vulcanizing machine structure of the liquid material mold, and it is difficult to manufacture products with a long size. In addition, the polyurethane material has poor aging resistance, oil resistance, water resistance and chemical solvent resistance. There are also methods of directly using an integrated rubber protective sleeve. The shape and size of the integrated rubber protective sleeve are determined according to the shape and size of the metal part, and the integrated rubber protective sleeve is molded and fitted on the metal part to prevent damage to the metal part. However, this method has the following technical problems: first, the integrated rubber protective sleeve needs to be removed from the mold core after molding, which can easily cause the rubber protective sleeve to tear, especially for the integrated rubber protective sleeve with large middle size and small size at both ends. Second, when the integrated rubber protective sleeve is fitted on the metal part, it is very difficult to fit when the size of the metal part is large, which greatly wastes manpower and slows down production efficiency. Finally, it is difficult to control the size of the rubber product, and due to the particularity of the military industry, there is no design drawing for some metal part rubber protective sleeves, so the size can only be determined by on-site observation and local mapping, resulting in a mismatch between the size of the integrated rubber protective sleeve and the corresponding metal part, which makes installation difficult or the protective effect invalid.

[0004] Therefore, it is necessary to provide a new technical solution to improve one or more problems in the above-mentioned solution. Utility Model Content

[0039] The present example embodiment first provides a new type of metal part protective sleeve. Referring to Figures 1 to 10 The new type of metal part protective sleeve includes a rubber protection mechanism 100 and a connecting mechanism 200. The rubber protection mechanism 100 has a side wall with an openable opening for wrapping around the non-processed area of the outer wall of the metal part 300. The connecting mechanism 200 is fixed to the position corresponding to the force point 310 of the metal part 300 on the outside of the rubber protection mechanism 100, and is used to gather and fix the two sides of the opening of the rubber protection mechanism 100 to the middle when the protective sleeve is used. The force point 310 is a plurality of position points selected in the length or circumference direction of the metal part 300.

[0040] Through the above-mentioned new type of metal part protective sleeve, the combination of the rubber protection mechanism 100 and the connecting mechanism 200 can adopt a rubber part body 110 with an opening, thereby avoiding the problems of difficult demolding and product tearing during the production of an integrated rubber protective sleeve. In this way, the design and production of the protective sleeve can be carried out without obtaining the size of the fine metal part, and the performance of the protective sleeve is ensured, such as aging resistance, oil resistance, water resistance, and chemical solvent resistance. At the same time, single person can realize sleeve installation, reduce labor cost, improve production efficiency, and avoid installation difficulties or protective failure caused by design or processing size deviation.

[0041] It should be noted that, as Figure 5 shown, it is a semi-finished metal part 300 diagram, wherein the processing area 320 needs to be processed by welding and polishing, and other parts need to be protected by soft elastomer material to ensure that the other parts of the metal part 300 are not damaged during processing. According to the length size of the part, the position of the processing area 320, and the three points in the length direction of the metal part 300 as the force points, the connecting mechanism 200 is fixed to the position corresponding to the three points on the side wall near the opening of the rubber protection mechanism 100, thereby effectively avoiding the processing area 320 and the protective sleeve can be tightly fixed on the part. The fixing position of the hook and loop fastener is different for different products, and the specific position of the product is determined by the specific product.

[0042] In one embodiment, the rubber protection mechanism 100 includes a rubber part body 110 and a reserved area 120. The rubber part body 110 is an open structure, and the inner wall surrounded by the opening after merging has the same shape as the outer wall of the metal part 300. The force point 310 corresponds to one end of the opening of the rubber part body 110. The reserved area 120 is located on the rubber part body 110 and corresponds to the processing area 320 of the outer wall of the metal part 300.

[0043] Optionally, further, as Figures 6-10As shown, the shape of the rubber member body 110 includes a strip shape and a cylindrical shape with an opening.

[0045] In one embodiment, the connecting mechanism 200 includes a first fixing member 210 and a second fixing member 220.

[0046] The fixed end of the second fixing member 220 is fixed to a position corresponding to the force point 310 at one end of the opening of the rubber member body 110, and the connecting end is close to the other end of the opening of the rubber member body 110.

[0047] The fixed end of the first fixing member 210 is fixed to the other end of the opening of the rubber member body 110, and the fixed end of the second fixing member 220 is located on the same straight line in the width direction, and the connecting end is close to the second fixing member 220 and connected to the connecting end of the second fixing member 220.

[0048] Further, optionally, the first fixing member 210 includes a first fixing belt 211 and a first fixing part 212, and the first fixing belt 211 is fixedly connected to the rubber member body 110 through the first fixing part 212; the second fixing member 220 includes a second fixing belt 221 and a second fixing part 222, and the second fixing belt 221 is fixedly connected to the rubber member body 110 through the second fixing part 222.

[0049] The end of the first fixing belt 211 away from the first fixing part 212 has a corresponding bonding area 230 with the end of the second fixing belt 221 away from the second fixing part 222, which is used to bond the first fixing belt 211 and the second fixing belt 221.

[0050] It should be noted that the part of the first fixing belt 211 and the second fixing belt 221 in contact has an area that can be bonded to each other when in contact, such as bonding glue, magic tape, Velcro, protrusions and fixing grooves, etc. Any processing method that can detachably fix the two.

[0051] In one embodiment, the connecting mechanism 200 is a Velcro, the first fixing member 210 is the buckle surface of the Velcro, and the second fixing member 220 is the adhesive surface of the Velcro. The buckle surface of the Velcro and the adhesive surface of the Velcro are bonded when they touch.

[0052] It should be noted that, as Figure 4The schematic diagram shows that the fastening surface of the hook-and-loop fastener is adhered to the adhering surface of the hook-and-loop fastener. The tightness of the rubber part body 110 can be adjusted by adjusting the adhering position. In use, the rubber part body 110 is opened, and is sleeved on the metal part to be protected. Then, the fastening surface of the hook-and-loop fastener is adhered to the adhering surface of the hook-and-loop fastener.

[0053] In one embodiment, the first fixing part 212 and the second fixing part 222 are fixedly connected to the rubber part body 110 by sewing threads.

The fastening surface of the hook-and-loop fastener is cut into a long strip, and a fixed sewing area is marked. A surplus size can be left. The fixed sewing area of the fastening surface of the hook-and-loop fastener is fixedly sewn at the other end of the rubber part, and the corresponding positions of the two ends correspond to each other.

[0055] Further, the sewing thread has an X-shaped pattern in which four points are sequentially connected.

[0056] It should be noted that, as shown in Figures 1-4 By using the X-shaped sewing method in which four points are sequentially connected, the fixing effect can be enhanced, and the connection mechanism 200 can be tightly connected and not fall off.

The extruded rubber is formed into a required semi-finished product shape by the mouth tool. Then, the rubber is shaped and the molecules are cross-linked in a hot drying channel by a track type electric heating air drying box, so as to be vulcanized into a required semi-finished product.

[0059] Alternatively, the manufacturing method of the rubber part body 110 further includes a mold molding vulcanization method. Specifically, the rubber material is returned to a sheet by a rubber mill, is cut into a strip or a sheet by a cutting machine or manually, and is filled into a corresponding mold. The rubber is shaped and the molecules are cross-linked in the mold by high temperature and pressure of a flat vulcanizing machine, so as to be vulcanized into a required semi-finished product.
