Description

Technical Field

[0001] This utility model relates to the field of punching equipment technology, specifically to a punching equipment for refrigerator sheet metal parts. Background Technology

[0002] Refrigerators are common appliances in our lives, and there are various types and sizes of refrigerators. The shell of a refrigerator is mostly made of stainless steel. In the sheet metal processing of the shell, one step is to punch holes in the sheet. Under the current technology, sheet metal punching usually involves placing the sheet on a lower stamping die, and the upper die applies pressure perpendicular to the sheet to achieve the purpose of punching.

[0003] Currently, existing refrigerator sheet metal punching equipment typically requires manual placement of sheet metal pieces one by one onto the lower template of the punch press. The clamps are then manually adjusted to the appropriate positions before being used to clamp and secure the edges of the sheet metal. After punching, the clamps must be removed before the sheet metal can be taken out. However, existing refrigerator sheet metal punching equipment directly punches holes in the sheet metal, causing bending around the holes and reducing the punching effect. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a punching device for refrigerator sheet metal parts, which can conveniently punch holes in refrigerator sheet metal parts and improve the punching effect of refrigerator sheet metal parts.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a refrigerator sheet metal punching device, comprising a base, a top plate mounted above the base via a vertical rod, and a punching mechanism mounted on the base for punching refrigerator sheet metal parts. The punching mechanism includes a second positioning post slidably mounted on the base, a fixed rod mounted on the bottom end face of the top plate and located directly above the second positioning post, a moving component mounted on the bottom end face of the top plate and controlling the movement of the fixed rod on the bottom end face of the top plate, a stamping post fixedly mounted on the bottom end of the fixed rod, a first positioning post movably sleeved on the fixed rod body through a first positioning hole at its end, a limiting spring movably sleeved on the fixed rod body and fixedly connected at both ends to the top end of the fixed rod and the top of the first positioning post, a linkage component mounted between the fixed rod and the second positioning post, and a stamping component mounted on the top plate and controlling the movement of the fixed rod towards the second positioning post. When the limiting spring is in its normal extended state, the bottom end of the first positioning post is located below the stamping post; a second positioning hole is provided on the end face of the second positioning post.

[0006] Preferably, a limiting block with a limiting groove on the top end face of the base is fixedly provided, and a through groove communicating with the inside of the limiting groove is provided on the symmetrical side of the limiting block, and the bottom end of the second positioning column is slidably provided on the bottom wall of the limiting groove.

[0007] Preferably, the linkage component includes a first connecting rod that is horizontally arranged and passes through the through groove and is fixedly connected at one end to the bottom of the side of the second positioning post; a second connecting rod that is parallel to the first connecting rod and is fixed at one end to the top of the fixing rod; and a sliding rod that is vertically fixed at one end of the first connecting rod away from the top of the second positioning post. A limiting rod is fixedly arranged on the side of the sliding rod, and the sliding rod and the limiting rod are movably inserted through the end of the second connecting rod away from the fixing rod.

[0008] Preferably, the stamping assembly includes a lifting block disposed on the bottom end face of the top plate and a stamping cylinder fixedly disposed on the top end face of the top plate in a vertical direction. The output end of the stamping cylinder passes through the top plate and is connected to the top end face of the lifting block. The bottom end of the lifting block is connected to a second connecting rod through a moving assembly.

[0009] Preferably, the moving component includes a transverse lead screw disposed in a transverse moving groove on the bottom end face of the lifting block, a transverse block threadedly connected to the body of the transverse lead screw, a longitudinal rod disposed longitudinally and fixedly connected to the bottom end of the transverse block on its top side, a longitudinal lead screw passing through a longitudinal groove on the bottom side of the longitudinal rod, a longitudinal block threadedly connected to the body of the longitudinal lead screw, and a motor for driving the transverse lead screw and the longitudinal lead screw to rotate.

[0010] Preferably, the drilling mechanism further includes two first telescopic rods that are symmetrically and vertically arranged on the top end face of the base about the limiting block, a second telescopic rod that is arranged vertically on the top of the first telescopic rod, two clamping rods arranged on both sides of the top of the limiting block, and two electromagnets arranged on the ends of the first telescopic rod. The first telescopic rod is movably fitted with a first spring that is connected to the two electromagnets at its two ends; the second telescopic rod is movably fitted with a second spring that is connected to the ends of the second telescopic rod at its two ends.

[0011] The beneficial effects of this utility model are as follows: The sheet metal parts of the refrigerator that need to be drilled are placed on the second positioning post on the base. The stamping assembly drives the fixing rod to move downward, which can punch and drill holes in the sheet metal parts located on the second positioning post. Before the stamping post on the fixing rod contacts the sheet metal parts, when the bottom end of the first positioning post, which is movably sleeved on the fixing rod, is in contact with the surface of the sheet metal parts, the holes in the sheet metal parts are clamped and fixed by the first and second positioning posts. When the stamping assembly continues to move downward, the limit spring is compressed, which clamps and fixes the sheet metal parts by the first and second positioning posts before punching and drilling. This avoids bending of the sheet metal parts at the drilling positions during punching and drilling, making it convenient to drill holes in refrigerator sheet metal parts and improving the drilling effect.

[0017] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are only preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the embodiments without creative effort are all within the protection scope of this utility model.

[0018] Please see Figure 1-3 A refrigerator sheet metal punching device includes a base 1, a top plate 2 mounted above the base 1 via a vertical rod 3, and a punching mechanism mounted on the base 1 for punching refrigerator sheet metal parts. The punching mechanism includes a second positioning post 12 slidably mounted on the base 1, a fixing rod 8 mounted on the bottom end face of the top plate 2 and located directly above the second positioning post 12, a moving component mounted on the bottom end face of the top plate 2 and controlling the movement of the fixing rod 8 on the bottom end face of the top plate 2, a punching post 22 fixedly mounted on the bottom end of the fixing rod 8, and a first positioning post with a first positioning post at the end. The first positioning post 10 is movably sleeved on the body of the fixed rod 8; the limiting spring 9 is movably sleeved on the body of the fixed rod 8 and its two ends are respectively fixedly connected to the top end of the fixed rod 8 and the top of the first positioning post 10; the linkage assembly is set between the fixed rod 8 and the second positioning post 12; and the stamping assembly is set on the top plate 2 and controls the fixed rod 8 to move towards the second positioning post 12. When the limiting spring 9 is in the normal extended state, the bottom end of the first positioning post 10 is located below the stamping post 22; a second positioning hole 13 is opened on the end face of the second positioning post 12.

[0019] like Figure 1-3 As shown, the location where the refrigerator sheet metal needs to be drilled is placed directly on the top end face of the second positioning post 12. The stamping assembly drives the fixing rod 8 to move downwards, and the bottom end of the first positioning post 10, which is movably sleeved on the body of the fixing rod 8, is in contact with the surface of the sheet metal. During the downward movement of the fixing rod 8, the limiting spring 9 is gradually compressed, which facilitates the clamping and fixing of the sheet metal by the first positioning post 10 and the second positioning post 12. The stamping post 22 set at the end of the fixing rod 8 drills holes in the surface of the sheet metal. The drilling location on the surface of the sheet metal is positioned and clamped by the first positioning post 10 and the second positioning post 12, which avoids bending of the drilling location on the surface of the sheet metal. This allows for convenient drilling of the refrigerator sheet metal and improves the drilling effect of the refrigerator sheet metal.

[0020] A limiting block 4 with a limiting groove 5 on its top end face is fixedly provided on the top end face of the base 1. A through groove 6 that communicates with the inside of the limiting groove 5 is provided on the symmetrical side of the limiting block 4. The bottom end of the second positioning post 12 is slidably provided on the bottom wall of the limiting groove 5.

[0021] The linkage component includes a first connecting rod 14 that is horizontally arranged and passes through the through groove 6 and is fixedly connected at one end to the bottom of the side of the second positioning post 12; a second connecting rod 20 that is parallel to the first connecting rod 14 and is fixed at one end to the top end of the fixing rod 8; and a sliding rod 15 that is vertically fixed at one end of the first connecting rod 14 away from the top of the second positioning post 12. A limiting rod 16 is fixedly arranged on the side of the sliding rod 15, and the sliding rod 15 and the limiting rod 16 are movably inserted through the end of the second connecting rod 20 away from the fixing rod 8.

[0022] like Figure 1-2 As shown, when the sheet metal part is placed on the second positioning post 12, the moving component and the stamping component drive the fixing rod 8 to move on the bottom end of the top plate 2. At this time, the first connecting rod 14 and the second connecting rod 20 drive the second positioning post 12 to move synchronously with the fixing rod 8, ensuring that the second positioning post 12 is located directly below the fixing rod 8. This ensures that when the fixing rod 8 is moved downward by the stamping component, the stamping post 22 set on the bottom end of the fixing rod 8 passes through the sheet metal part into the second positioning hole 13. This facilitates ensuring that when drilling holes at various positions on the surface of the sheet metal part, the drilling position of the sheet metal part is fixedly clamped by the first positioning post 10 and the second positioning post 12, avoiding bending around the drilling position of the sheet metal part.

[0023] The stamping assembly includes a lifting block 7 disposed on the bottom end face of the top plate 2, and a stamping cylinder 11 fixedly disposed on the top end face of the top plate 2 in a vertical direction. The output end of the stamping cylinder 11 passes through the top plate 2 and is connected to the top end face of the lifting block 7. The bottom end of the lifting block 7 is connected to the second connecting rod 20 through a moving assembly.

[0024] like Figure 1-2 As shown, the lifting block 7 is moved downward by the stamping cylinder 11, which in turn moves the fixed rod 8 set on the lifting block 7 downward, thereby punching and drilling holes on the surface of the sheet metal part through the stamping column 22 set on the end of the fixed rod 8.

[0025] The moving assembly includes a transverse lead screw 24 disposed in a transverse moving groove 23 on the bottom end face of the lifting block 7, a transverse block 25 threadedly connected to the body of the transverse lead screw 24, a longitudinal rod 26 disposed longitudinally and fixedly connected to the bottom end of the transverse block 25 on its top side, a longitudinal lead screw 28 passing through a longitudinal groove 27 on the bottom side of the longitudinal rod 26, a longitudinal block 29 threadedly connected to the body of the longitudinal lead screw 28, and a motor for driving the transverse lead screw 24 and the longitudinal lead screw 28 to rotate.

[0026] like Figure 2-3As shown, when drilling holes at different positions on the surface of a sheet metal part, the motor drives the horizontal lead screw 24 to rotate, causing the horizontal block 25, which is threaded onto the body of the horizontal lead screw 24, to slide stably within the horizontal moving groove 23. This, in conjunction with the motor driving the vertical lead screw 28 to rotate, causes the vertical block 29 to move the fixed rod 8 on the bottom end face of the lifting block 7. This facilitates stable drilling at various positions on the surface of the sheet metal part through the stamping column 22 at the bottom end of the fixed rod 8, making it convenient to drill holes in the refrigerator sheet metal part and improving the drilling effect.

[0027] The drilling mechanism also includes two first telescopic rods 17 that are symmetrically and vertically arranged about the left and right sides of the limiting block 4 on the top end face of the base 1, a second telescopic rod 18 that is arranged vertically on the top of the first telescopic rod 17, two clamping rods 19 that are arranged on both sides of the top of the limiting block 4, and two electromagnets that are arranged on both ends of the first telescopic rod 17. The first telescopic rod 17 is movably fitted with a first spring that is connected to the two electromagnets at both ends; the second telescopic rod 18 is movably fitted with a second spring that is connected to the two ends of the second telescopic rod 18.

[0028] like Figure 1-2 As shown, the sheet metal part is placed on the top end face of the limiting block 4. Then, by controlling the magnetic poles of the two electromagnets to be opposite at their adjacent ends, the two electromagnets are brought closer to each other, compressing the first spring on the first telescopic rod 17, which drives the second telescopic rod 18 and the clamping rod 19 to move downward. This facilitates the clamping and fixing of the sheet metal part located on the end face of the limiting block 4 by the two clamping rods 19, thus facilitating the initial fixing of the sheet metal part located on the top end face of the limiting block 4 and ensuring the stability of the sheet metal part's position on the top of the limiting block 4.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
