Description

Technical Field

[0001] The invention belongs to the technical field of automobile parts processing, and in particular relates to a forging processing device for automobile parts. Background Art

[0002] Auto parts are the components that make up a car and the products that serve it. There are many different types of auto parts, and processing engine cylinder heads, among them, requires forging. This is a forming process whereby the forging machine's hammer, anvil, punch, or die applies pressure to the blank, causing it to plastically deform, ultimately achieving the desired shape and size.

[0003] The existing forging processing equipment has the following problems:

[0004] Existing forging equipment generates a lot of noise when forging a blank, and workers who are closer to the blank suffer greater damage. It does not have the ability to reduce the noise generated by forging the blank, which causes serious damage to the workers' hearing system. Therefore, it cannot meet the existing demand for the use of forging equipment. Summary of the Invention

[0005] In view of the above situation, in order to overcome the defects of the existing technology, the present invention provides a forging device for automotive parts that can reduce the noise generated by forging blanks and reduce the chance of noise damaging the hearing system of operators.

[0006] The technical solution adopted in this scheme is as follows: This scheme proposes a forging processing device for automotive accessories, including a base, a sliding frame, a positioning hammer mechanism and a pressure-energy sound-damping mechanism.

The positioning hammer mechanism includes a guide mechanism, a sliding mechanism, a limiting mechanism and a punching mechanism. The guide mechanism is arranged in the middle position of the upper wall of the base, the sliding mechanism is arranged on the outside of the sliding frame, the limiting mechanism is arranged on the side wall of the sliding mechanism, and the punching mechanism is arranged at the end of the sliding frame away from the base. The pressure-energy sound-damping mechanism includes a charging mechanism and an ejection mechanism. The charging mechanism is arranged on the side wall of the guide mechanism, and the ejection mechanism is arranged at the end of the charging mechanism away from the guide mechanism.

[0007] As a further preferred embodiment of the present invention, the guide mechanism includes a guide sleeve, a guide column and a rebound spring, the guide sleeve is arranged on the upper wall of the base, the guide column is slidably arranged on the inner wall of the guide sleeve, the rebound spring is arranged between the guide column and the bottom wall of the guide sleeve, and the rebound spring is extended; the sliding mechanism includes a sliding block and a forged concave platform, the sliding block is slidably arranged on the outside of the sliding frame, the forged concave platform is arranged on the side of the sliding block away from the sliding frame, and the forged concave platform is arranged on the upper wall of the guide column; the limiting mechanism includes a limiting column, a limiting plate, a limiting spring and an arc plate, multiple groups of limiting columns are arranged through the side wall of the forged concave platform, and the limiting plate is arranged The limiting column is away from the side of the forging recess, the limiting spring is arranged between the limiting plate on the outside of the limiting column and the forging recess, and the arc plate is arranged on the side wall of the limiting column inside the forging recess; the punching mechanism includes a punching sleeve, a punching column, a reset spring, a downward pressure magnet and a driving electromagnet, the punching sleeve is arranged on the side wall of the sliding frame above the forging recess, the punching column is slidably arranged on the inner wall of the punching sleeve, the reset spring is arranged between the upper wall of the punching column and the upper wall of the punching sleeve, the reset spring is extended, the downward pressure magnet is arranged on the upper wall of the punching column, the driving electromagnet is arranged through the inner wall of the top of the punching sleeve, and the downward pressure magnet and the driving electromagnet are arranged opposite to each other.

[0008] When in use, the driving electromagnet is energized to generate magnetism, and the driving electromagnet uses the deformation of the reset spring to drive the punching column to retract into the inside of the punching sleeve, pulling the limit plate. The limit plate uses the deformation of the limit spring to drive the limit column to slide along the inner wall of the forging recess. The limit column drives the arc plates to move back to each other, and the distance between the arc plates increases. The automobile part blank to be forged is placed on the bottom wall of the forging recess, and the limit plate is released. The limit column drives the arc plate to fit with the automobile part blank through the elastic reset of the limit spring. The automobile part blank is fixed in the middle position of the bottom wall of the forging recess, reducing the chance of the automobile part blank shifting during the forging process.

[0009] Preferably, the charging mechanism includes a pipe clamp, a charging tube, a charging box, a one-way air intake valve and an annular block. The pipe clamp is symmetrically arranged on the upper wall of the base away from the sliding frame. The charging tube passes through the pipe clamp and is arranged on the bottom side wall of the guide sleeve. The charging tube is connected to the guide sleeve. The charging box is connected on the side of the charging tube away from the guide sleeve. The annular block is arranged on the bottom wall of the guide sleeve. The one-way air intake valve passes through the base and the guide sleeve and is arranged on the inner wall of the annular block; the ejection mechanism includes an ejection sleeve, an ejection plate, a sound insulation column and a sound insulation cotton layer. Multiple groups of the ejection sleeves are connected and arranged on the upper wall of the charging box. The ejection plate is slidably arranged inside the ejection sleeve. The sound insulation column is arranged on the upper wall of the ejection plate, and the sound insulation cotton layer is arranged on the outside of the ejection sleeve.

[0010] During use, when the automotive parts blank is being forged, the forging concave table is impacted and then descends by deformation of the rebound spring. The forging concave table squeezes the gas inside the guide sleeve into the pipe clamp through the guide column. The charging tube disperses the impact gas into the ejection sleeve through the charging box. The ejection sleeve ejects the sound insulation column through the ejection plate. The sound insulation column extends from the inside of the ejection plate to the outside of the forging concave table. The sound insulation column can block the noise generated by forging the automotive parts blank. The operator stands on one side of the sound insulation column to reduce the chance of noise damaging the operator's hearing system.

[0011] Specifically, a controller is provided on the upper wall of the base.

[0012] Wherein, the controller is electrically connected to the driving electromagnet.

[0013] The beneficial effects achieved by adopting the above structure are as follows:

[0014] Compared with the existing technology, this scheme adopts the method of impact and extrusion to forge automobile parts blanks. Through the setting of the positioning hammer mechanism and the pressure-energy sound insulation mechanism, the guiding mechanism, the sliding mechanism, the limiting mechanism, the punching mechanism, the charging mechanism and the ejection mechanism cooperate with each other to reduce the noise intensity generated by the punching column when forging the automobile parts blank. By extending the distance that the punching column squeezes the automobile parts blank, the punching column is finally introduced into the guide sleeve during the forging process of the automobile parts blank, and the pushing ability of the guide column is utilized to transport the gas inside the guide sleeve to the charging box, thereby pushing the sound insulation column out of the ejection sleeve to block the noise generated during the forging operation of the automobile parts blank, thereby improving the forging efficiency of the automobile parts blank to a certain extent.

The pipe clamp 24 is symmetrically arranged on the upper wall of the base 1 away from the sliding frame 2. The charging pipe 25 passes through the pipe clamp 24 and is arranged on the bottom side wall of the guide sleeve 5. The charging pipe 25 is connected to the guide sleeve 5.

[0035] Specifically, a controller 32 is provided on the upper wall of the base 1 .

[0036] The controller 32 is electrically connected to the driving electromagnet 21 .

[0037] In specific use, in the initial state, the rebound spring 7 is in an extended setting, the guide column 6 slides along the inner wall of the guide sleeve 5 to inhale external air through the one-way air intake valve 27, the limit spring 14 is in a compressed setting, the distance between the arc plates 15 is at a minimum value, the return spring 19 is in an extended setting, the return spring 19 extends out of the inside of the punching sleeve 17, and the distance between the punching column 18 and the forging concave platform 10 is at a minimum value;

[0038] When it is necessary to forge the blank of the automobile parts, the controller 32 controls the driving electromagnet 21 to start, the driving electromagnet 21 is energized to generate magnetism, the driving electromagnet 21 and the pressing magnet 20 are arranged with opposite poles, the controller 32 controls the current passed into the driving electromagnet 21 to increase, the driving electromagnet 21 is fixed on the inner wall of the punching sleeve 17 and presses the magnet 20 by magnetic force, the driving electromagnet 21 uses the deformation of the reset spring 19 to drive the punching column 18 to retract into the inside of the punching sleeve 17, and manually pulls the limit plate 13, and the limit plate 13 is used to The deformation of the limit spring 14 drives the limit column 12 to slide along the inner wall of the forging concave platform 10, and the limit column 12 drives the curved plates 15 to move in opposite directions, and the distance between the curved plates 15 increases. The automobile part blank to be forged is placed on the bottom wall of the forging concave platform 10, and the limit plate 13 is released. The limit column 12 is elastically reset by the limit spring 14, driving the curved plate 15 to fit the automobile part blank. The automobile part blank is fixed in the middle position of the bottom wall of the forging concave platform 10, which can reduce the probability of the automobile part blank being offset during the forging process;

[0039] The controller 32 changes the magnetic pole of the driving electromagnet 21, so that the driving electromagnet 21 and the pressing magnet 20 are arranged with the same pole. The punching column 18 uses its own weight, the rebound force of the return spring 19, and the driving force of the driving electromagnet 21 to extend from the inside of the punching sleeve 17 to forge the automotive part blank fixed to the upper wall of the forging recess 10. During the forging process of the automotive part blank, the forging recess 10 is impacted and then descends due to the deformation of the rebound spring 7. The guide column 6 descends along the inner wall of the guide sleeve 5 and collides with the annular block 33, so that most of the forging noise enters the interior of the guide sleeve 5.

[0040] To prevent high temperatures from affecting the sound-absorbing performance of the sound-absorbing material, the forged concave platform 10 drives the hotter blank to extend away from the ejector sleeve 29 using the elasticity of the rebound spring 7. When the punched forged column 18 is in contact with the hot blank, the punched forged column 18 can block the radiation of part of the heat from the hot blank. As a result, when the sound insulation column 31 extends out of the ejector sleeve 29 and reaches the area of ​​the forged concave platform 10, the influence of the high temperature on the sound insulation column 31 can be reduced, thereby ensuring the sound absorption performance of the sound insulation cotton layer 34 and the ejector sleeve 29.

[0041] The forging concave table 10 squeezes the gas inside the guide sleeve 5 into the pipe clamp 24 through the guide column 6, and the charging tube 25 disperses the impactful gas into the ejection sleeve 29 through the charging box 26. The ejection sleeve 29 ejects the sound insulation column 31 through the ejection plate 30. The sound insulation column 31 extends from the inside of the ejection plate 30 to the outside of the forging concave table 10. The sound insulation column 31 can block the noise generated by forging the automotive parts blank. The operator stands on one side of the sound insulation column 31, thereby reducing the chance of noise damaging the operator's hearing system; the above operation can be repeated the next time it is used.

[0042] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0043] The above description of the present solution and its implementation methods is non-limiting. The drawings show only one implementation method of the present solution, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by this and, without departing from the purpose of the present solution, designs a similar structure and embodiment without creatively designing, they shall fall within the scope of protection of the present solution.
