If a certain amount of deformation is carried out during the heat treatment process, the surface of the product is prone to defects such as folding, pitting, and pits. In the subsequent surface treatment process, it is necessary to use flap wheels, grinding wheels, etc. to remove various defects on the surface of the product. Figure 4 The blank making process of the invention is as follows: blanking - chamfering - radial forging - heating and bending - finishing - spraying - final forging - trimming - annealing - sandblasting - finishing, etc., wherein heating and deformation are required in the third step of radial forging and the fourth step of heating and bending, and defects such as pitting, folding, and pits may occur on the surface of the product during this process. Due to the strict requirements of medical products, no defects on the surface are allowed, so it is necessary to polish and repair the product 100% of the entire surface after heating and bending in the fourth step. The current method is to polish and repair the product manually by holding it on a grinding machine. The disadvantages of this method are as follows: 1. Slow speed and low efficiency, with a workload of 100 to 150 pieces per person per day; 2. There are great safety hazards, and the operator's hand may be in close contact with the high-speed rotating flap wheel and cause injury; 3. It is not easy to use too much force during the operation, and too much force may cause improper force and cause the product to fly out, causing danger to personnel, but if the force is not applied, the defects of the product are difficult to polish and repair.

[0003] In view of the above problems, it is necessary to propose improvements. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "includes a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0025] See also Figure 1-6 , describe the embodiments of the present utility model in detail.

[0026] Example: Grinding tool for polishing and repairing the surface of special-shaped metal products, see Figure 1 As shown, it includes a grinding tool 1, which includes a grinding tool body 1-1. One end of the grinding tool body 1-1 is provided with a grinding top groove Ⅰ1-2 for adapting to the arc surface of the special-shaped metal product 2, and the other end of the grinding tool body 1-1 is provided with a grinding top groove Ⅱ1-3 for adapting to the arc surface of the special-shaped metal product 2.

[0027] When the special-shaped metal product 2 is ground by the above-mentioned structure, the grinding top groove at the end of the grinding tool is used to support the product so that the product is close to the grinding wheel for grinding and repair. This can effectively prevent people from approaching the grinding wheel, greatly reducing safety risks, ensuring the personal safety of the staff, and can improve work efficiency and reduce the work intensity of the operators.

[0028] In a specific implementation: see Figure 1-3 As shown, two opposite sides at one end of the grinding tool body 1-1 are provided with grinding top grooves Ⅰ1-2 for adapting to the arc surface of the special-shaped metal product 2, and two opposite sides at the other end of the grinding tool body 1-1 are provided with grinding top grooves Ⅱ1-3 for adapting to the arc surface of the special-shaped metal product 2.

[0029] By arranging grinding top grooves at both ends of the grinding tool body, it can be ensured that both ends of the grinding tool can be used, thereby increasing the service life.

[0030] In a specific embodiment: the grinding top groove Ⅰ1-2 and the grinding top groove Ⅱ1-3 are both 1 / 4 arc groove structures adapted to the arc surface of the special-shaped metal product 2. The grinding top groove Ⅰ1-2 and the grinding top groove Ⅱ1-3 are arranged to be arc grooves of different radius specifications according to the different diameters of the arc surface of the special-shaped metal product 2. The edges of the grinding top groove Ⅰ1-2 and the grinding top groove Ⅱ1-3 are rounded transitions.

[0031] Through the above structure, the multiple grinding top grooves on a grinding tool are made into various specifications, so that one tool can be used for pressing different diameters on special-shaped metal products, thereby improving the applicability of the tool. Figure 5 The state shown is that the grinding top groove Ⅰ1-2 is used to support the larger diameter part of the workpiece; refer to Figure 6 The state shown is that the grinding top groove II1-3 is used to support the smaller diameter part of the workpiece.

[0032] In this embodiment, with respect to the structure of the medical joint handle, preferably, the grinding top groove Ⅰ1-2 is The arc groove, the grinding top groove II1-3 is Arc groove. It can make the groove shape adapt to the outer surface structure of the joint disease, so as to better realize the polishing work. Of course, for the grinding of other heterogeneous metals, other sizes of grinding top grooves can also be made.

[0033] Preferably, in order to facilitate manual operation, the size of the grinding tool body 1-1 is set to 350mm*60mm*40mm, which is convenient for handholding and flexible in use.

[0034] Preferably, the grinding tool 1 is made of wood, which is light and soft, not only easy for operators to hold, but also will not cause crushing or bumping to the product where it contacts the product.

[0035] In a specific embodiment, a grip portion 1-4 is provided in the middle of the grinding tool body 1-1, and the grip portion 1-4 is a circular arc surface annular groove structure. This structure is convenient for human hand gripping and improves the comfort of operation.

[0036] The use of this grinding tool is as follows:

[0037] Take the grinding of the joint handle as an example, see Figure 5 and 6 As shown, during use, the grinding top groove of the grinding tool is used to support the product so that the product contacts the flap wheel 3, the left hand rotates the joint handle, the right hand holds the grinding tool, and the body force is used to support the joint handle so that it moves back and forth on the high-speed rotating flap wheel 3, thereby achieving the purpose of removing surface defects of the product. In addition, when using, the tool can also be leaned against the fulcrum of the equipment to reduce the strength of the operator through the principle of leverage.

[0038] The utility model changes the tooling so that the operator can increase the strength without worry and can complete the polishing and repair of various parts of the product more flexibly than hand-held, which greatly improves the work efficiency, reduces the work intensity of the operator, and increases the work efficiency from 100 to 150 pieces per day to 350 to 500 pieces.

[0039] The use of this tooling greatly reduces safety risks. The operator's body strength is applied to the product through the tooling. One hand does not need to touch the product, and the other hand only moves back and forth while the product rotates. It is sufficient to hold the farthest end of the product without touching the high-speed flap wheel, thereby improving operational safety.
