Technical Field

[0001] The utility model relates to the technical field of steel ball forging, in particular to a forging device for wear-resistant steel balls. Background Art

[0002] Steel balls are divided into grinding steel balls, forging steel balls, and casting steel balls according to the production and processing technology. They are divided into bearing steel balls, stainless steel balls, carbon steel balls, copper bearing steel balls, alloy balls, etc. according to the processing materials. Forging refers to the process of forging metal in a red-hot state through equipment such as air hammers or presses to produce objects. This operation is usually achieved through a forging device for wear-resistant steel balls. The heavy hammer body is combined with a forging mold with an arc-shaped groove to hammer the softened wear-resistant steel ball, thereby hammering the steel block into a spherical shape.

[0003] When a wear-resistant steel ball forging device is used to forge a steel ball, the steel ball is usually in a calcined state. When a heavy hammer acts on the steel ball, sparks or debris usually fly, which may hurt people around. Therefore, a wear-resistant steel ball forging device is proposed to solve the above problem. Utility Model Content

[0004] The purpose of the utility model is to provide a forging device for wear-resistant steel balls to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A forging device for wear-resistant steel balls includes a heavy press, a forging hammer, a workbench and bolts, wherein the upper end surface of the workbench is provided with a forging model, the outer side of the forging model is fixedly connected to a mounting block with an arc-shaped side, the inner side of which is provided with a first screw hole, the upper end surface of the workbench is provided with a second screw hole with the same aperture size, the aperture size of the first screw hole is equal to the aperture size of the second screw hole, the upper end surface of the workbench is provided with a slide groove, the inner side of the slide groove is provided with a guide rod, the two ends of the guide rod are fixedly connected to the inner wall of the slide groove, the outer side of the guide rod is slidably connected to a protrusion, the top of the protrusion is fixedly connected to a baffle with an L-shaped longitudinal section, and the baffles are arranged at equal angles with the same center of the circle on the outside of the forging model.

[0007] Preferably, a first spring is sleeved on the outer side of the guide rod, and the two ends of the first spring are fixedly connected to the inner wall of the slide groove and one side of the protrusion respectively. A second spring is fixedly connected to the side of the protrusion away from the first spring, and the other end of the second spring is fixedly connected to the inner wall on the other side of the slide groove. The second spring is sleeved on the outer side of the guide rod.

[0008] Preferably, a plurality of positioning rods of equal size are fixedly connected to the bottom of the forging mold, and a positioning groove is provided on the upper end surface of the workbench, and the positioning rods are engaged with the inner side of the positioning groove.

[0010] Preferably, the baffle is arranged on the top of the workbench, and the baffle and the workbench are arranged to slide relative to each other.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. In the present invention, a structure consisting of a chute, a guide rod, a protrusion, and a baffle is provided on the outside of the forging model. When the baffle is pushed, the baffle can move along with the protrusion. The protrusion slides inside the chute under the guidance of the guide rod, thereby changing the position of the baffle, so that it can be sleeved on the outside of forging models of different sizes. When the heavy press drives the forging hammer to forge the steel piece placed on the forging model, the baffle can block some debris or sparks, thereby minimizing the splash of debris or sparks and providing some protection for people around.

[0013] 2. In the utility model, a structure consisting of a positioning groove, a positioning rod and a mounting block is provided. The positioning rod is first engaged with the inner side of the positioning groove, and then a bolt is passed through the first screw hole on the inner side of the mounting block and the second screw hole of the workbench, so as to position and install the forging model. The engagement of the positioning groove and the positioning rod can make the forging model less likely to move after being subjected to the force of the forging hammer, thereby solving the problem that the movement of the forging model may affect the production of wear-resistant steel balls.

[0027] See also Figure 1-6 , the utility model provides a technical solution:

[0028] A forging device for wear-resistant steel balls includes a heavy press 1, a forging hammer 2, a workbench 3 and bolts. A forging model 6 is provided on the upper end surface of the workbench 3. A mounting block 7 with an arc-shaped side is fixedly connected to the outer side of the forging model 6. A first screw hole 8 is provided on the inner side of the mounting block 7. A second screw hole 9 with an equal aperture is provided on the upper end surface of the workbench 3. The aperture size of the first screw hole 8 is equal to the aperture size of the second screw hole 9. A slide groove 10 is provided on the upper end surface of the workbench 3. A guide rod 11 is provided on the inner side of the slide groove 10. Both ends of the guide rod 11 are fixedly connected to the inner wall of the slide groove 10. A protrusion 12 is slidably connected to the outer side of the guide rod 11. The top of the protrusion 12 is fixedly connected to a baffle 13 with an L-shaped longitudinal section. The baffles 13 are arranged at equal angles on the outer side of the forging model 6 with the same center.

[0029] The outer side of the guide rod 11 is sleeved with a first spring 14, and the two ends of the first spring 14 are fixedly connected to the inner wall of the slide 10 and one side of the protrusion 12 respectively. The side of the protrusion 12 away from the first spring 14 is fixedly connected with a second spring 15, and the other end of the second spring 15 is fixedly connected to the inner wall of the other side of the slide 10. The second spring 15 is sleeved on the outer side of the guide rod 11. This arrangement enables the installation of the first spring 14 and the second spring 15 to be realized, and the protrusion 12 is protected to a certain extent; the bottom of the forging model 6 is fixedly connected with a plurality of positioning rods 5 of equal size, and the workbench 3 is fixedly connected to the bottom of the forging model 6. A positioning groove 4 is provided on the upper end surface, and a positioning rod 5 is engaged with the inner side of the positioning groove 4. This arrangement makes it difficult for the forging model 6 to move after being subjected to the force of the forging hammer 2 due to the engagement of the positioning groove 4 and the positioning rod 5; the mounting blocks 7 are arranged in an equiangular array with the same center, and there are three mounting blocks 7. This arrangement makes it possible to install the forging model 6 through the mounting blocks 7; a baffle 13 is arranged on the top of the workbench 3, and the baffle 13 and the workbench 3 are arranged to slide relative to each other. This arrangement allows the baffle 13 to block some debris or sparks, thereby minimizing the splashing of debris or sparks.

[0030] Working process: All electrical appliances in the present invention are provided with an external power supply. When the forging device for wear-resistant steel balls is used to forge the steel balls, the steel balls to be processed after calcination are placed on the forging model 6, and the heavy press 1 is started. The heavy press 1 drives the forging hammer 2 connected thereto to move toward the workbench 3. The forging hammer 2 acts on the steel parts on the forging model 6, and then the steel parts are manually rotated so that the steel parts are continuously acted upon by the forging hammer 2 and the forging model 6, and finally wear-resistant steel balls are formed. In this process, the steel balls after calcination are acted upon by the forging hammer 2 with a large amount of force, and debris or sparks may be generated. The baffle 13 can block part of the debris or sparks, minimize the splashing of debris or sparks, and provide some protection for people around. When the forging model 6 needs to be replaced, Disengage one side of the bolt from the second screw hole 9 and the first screw hole 8 opened on the inner side of the mounting block 7, and then drag the forging model 6 upward to disengage the positioning rod 5 from the positioning groove 4, thus completing the disassembly of the forging model 6. The reverse operation can be used to install the forging model 6. The engagement of the positioning groove 4 and the positioning rod 5 can make the forging model 6 less likely to move after being subjected to the force of the forging hammer 2, and push the baffle 13. The baffle 13 can move with the protrusion 12. The protrusion 12 slides inside the slide groove 10 under the guidance of the guide rod 11, thereby changing the position of the baffle 13, so that the baffle 13 can be sleeved on the outside of forging models 6 of different sizes. In this process, the first spring 14 and the second spring 15 will be stretched or compressed, thereby providing certain protection for the protrusion 12.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
