Description

Technical Field

[0001] The utility model relates to the technical field of ferrous metal casting, in particular to a forming punching device for ferrous metal casting. Background Art

[0002] Ferrous metals mainly refer to iron and its alloys, such as steel, pig iron, iron alloys, cast iron, etc. Casting is a method of pouring liquid metal into a casting cavity that is adapted to the shape of the part, and waiting for it to cool and solidify to obtain parts or blanks. After casting, the parts are still in the blank stage, so secondary processing operations such as grinding, polishing, stamping, and deburring are required.

[0003] The existing stamping technology does not have a centering function. Therefore, when performing the center stamping operation on a part, an additional centering tool is required to find the center of the part before stamping. At the same time, in the stamping project, due to the large impact force, if the parts are not fixed, it is very easy for the parts to loosen and deviate, which in turn leads to insufficient stamping accuracy during the stamping process.

[0004] For example, Chinese patent CN220049629U discloses a forming stamping device for ferrous metal casting. By setting the cooperation between the centering clamping block and the positioning rod, when the positioning rod is lowered, the driving groove of the centering clamping block is driven by the folding rod segment thereon, so that the centering clamping block moves in opposite directions, which can not only clamp and fix the parts, but also center the parts, thereby realizing the simultaneous stamping, centering and clamping, and integrating multiple functions, reducing the use of equipment and reducing the space occupied.

[0005] However, the outer end of the punching device is not provided with a protective structure, so that it is impossible to protect the debris that may be splashed during the punching process, which endangers the safety of surrounding workers.

[0006] For this reason, we urgently need to provide a kind of black metal casting forming punching device with protective function. Utility Model Content

[0007] The purpose of the utility model is to provide a forming stamping device for ferrous metal casting, so as to solve the problem that the outer end of the stamping device proposed in the above background technology is not provided with a protective structure, so that it is impossible to protect the debris that may fly out during the stamping process, which endangers the safety of surrounding workers.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a forming stamping device for ferrous metal casting, comprising a base plate and a support cover, wherein the support cover is fixedly connected to the upper side of the base plate, and the upper end of the base plate is connected to a stamping mechanism, wherein the stamping mechanism comprises a stamping unit and a clamping unit, wherein the stamping unit is arranged at the upper end of the base plate, and the clamping unit is arranged above the base plate.

[0009] The stamping unit includes a telescopic member, an upper template, a lower template, a guard door, a handle, a rectangular frame, a first spring, a sliding plate and a sleeve frame. The telescopic member is fixedly connected to the upper middle position of the support cover, the upper template is fixedly connected to the lower end of the output shaft of the telescopic member, the lower template is fixedly connected to the upper middle position of the bottom plate, the guard door is hinged to the front side of the support cover, the handle is fixedly connected to the lower middle position of the front side of the guard door, the rectangular frame is fixedly connected to the lower middle position of the front side of the guard door, the first spring is fixedly connected to the inner top end of the rectangular frame, the sliding plate is fixedly connected to the lower end of the first spring, and the sleeve frame is fixedly connected to the front middle position of the bottom plate.

[0010] A further improvement is that the outer side of the sliding plate is slidably connected to the inner side of the rectangular frame, so that when the first spring is activated, the sliding plate can be driven to slide along the inner side of the rectangular frame, thereby limiting the movement of the sliding plate.

[0011] A further improvement is that the outer side of the lower end of the sliding plate is slidably connected to the inner side of the sleeve frame, so that after the guard door is rotated to the front end of the support cover, the first spring rebounds to push the sliding plate down, driving the lower end of the sliding plate to move down to the inner side of the sleeve frame, the guard door can be fixed to the front end of the support cover, and the front end of the support cover is closed, thereby preventing debris generated during the stamping process from splashing around.

[0012] A further improvement is that the clamping unit includes a top plate, a second spring, a pressure plate, a third spring and a push rod, the top plate is fixedly connected to the upper ends of the left and right sides of the upper template, the second spring is fixedly connected to the lower side of the top plate, the pressure plate is fixedly connected to the lower end of the second spring, the third spring is connected to the left and right ends inside the lower template, and the push rod is fixedly connected to the upper end of the third spring.

[0013] A further improvement is that the lower side of the pressing plate abuts against the upper side of the metal plate on the upper side of the lower template, so that when the upper template moves downward to punch the metal plate, the pressing plate will first contact the metal plate, and the second spring will be compressed to press the metal plate tightly onto the lower template, ensuring that it is fixed to the lower template without deviation when punching it.

[0014] A further improvement is that a circular groove is provided in the middle of the left and right ends of the lower template, the lower end of the third spring is fixedly connected to the inner bottom end of the circular groove, and the outer side of the push rod is slidably connected to the inner side of the circular groove. Therefore, after the metal plate is stamped and the upper template is lifted, the third spring will rebound and push the push rod upward, and at the same time, the push rod will push up the metal plate attached to the upper side of the lower template, preventing the metal plate from being adsorbed on the lower template after stamping and being difficult to remove.

[0015] A further improvement is that a rubber pad is fixedly connected to the lower side of the pressing plate and the upper side of the push rod, so that when the pressing plate and the push rod contact the metal plate, they both contact the outer side of the metal plate through the rubber pad on their outer sides, which can prevent the pressing plate and the push rod from scratching the outer surface of the metal plate.

[0016] In summary, the present application discloses a forming stamping device for ferrous metal casting.

[0017] The technical solution rotates the guard door to the front side of the support cover, and then pushes down the sliding plate through the rebound of the first spring, driving the lower end of the sliding plate to move down to the inner side of the sleeve frame, so that the guard door can be fixed to the front end of the support cover, closing the front end of the support cover, thereby preventing debris generated during the stamping process from splashing around.

[0018] Furthermore, when the upper template moves downward to stamp the metal plate, the pressure plate will first contact the metal plate, and the second spring will be compressed to press the metal plate tightly onto the lower template, ensuring that it is fixed to the lower template without deviation when stamping it.

The sleeve frame 309 is fixedly connected to the front middle position of the bottom plate 1. The outer side of the sliding plate 308 is slidably connected to the inner side of the rectangular frame 306. Therefore, when the first spring 307 bounces, it can drive the sliding plate 308 to slide along the inner side of the rectangular frame 306, thereby limiting the movement of the sliding plate 308.

[0029] The outer side of the lower end of the sliding plate 308 is slidably connected to the inner side of the sleeve frame 309. Therefore, after the guard door 304 is rotated to the front end of the support cover 2, the first spring 307 rebounds and pushes the sliding plate 308 downward, driving the lower end of the sliding plate 308 to move downward to the inner side of the sleeve frame 309, and the guard door 304 can be fixed to the front end of the support cover 2, and the front end of the support cover 2 is closed, thereby preventing the debris generated during the stamping process from splashing around.
