Description

Technical Field

[0001] The utility model relates to the field of stamping equipment, in particular to a hardware stamping and shaping device. Background Art

[0002] Hardware refers to tools made of gold, silver, copper, iron, tin and other metals through processing and casting, which are used to fix things, process things, and decorate. During the processing of hardware, stamping equipment is used for stamping. Stamping is a forming processing method that relies on presses and dies to apply external force to plates, strips, pipes and profiles to cause them to produce plastic deformation or separation, thereby obtaining workpieces (stamping parts) of the required shape and size. Stamping and forging are both plastic processing (or pressure processing), collectively known as forging. The blanks for stamping are mainly hot-rolled and cold-rolled steel plates and steel strips.

[0003] During the stamping process of hardware parts, it is necessary to use a shaping die to shape the hardware parts to prevent them from deforming and rebounding after stamping. Since the hardware parts fit closely with the shaping die, they can easily get stuck in the die and cannot be removed. Existing hardware stamping methods often use an ejector structure to eject the hardware parts. However, this method will reduce the fit between the hardware and the shaping die, and it is easy to leave scratches or indentations on the hardware during ejection, affecting the processing quality.

[0004] Patent publication number CN114393117A discloses a stamping die for automotive hardware parts that facilitates die head replacement. The die comprises a base with mounting blocks fixedly connected to both sides of the top of the base. The mounting blocks have mounting slots on their front faces, into which a lower die is inserted. The bottom of the lower die has a latching hole. A clamping device is mounted on the top of the lower die, which latches into the latching hole. A shrinking ejection device is mounted on the bottom of the clamping device, and a top plate is hingedly connected to the top of the inner wall of the latching hole. However, this stamping die utilizes a shrinking ejection device to shrink or eject the hardware, which can easily leave scratches or indentations on the hardware during ejection, affecting processing quality. Utility Model Content

[0005] The purpose of this utility model is to overcome the defects of the above-mentioned prior art and provide a hardware stamping and shaping device, which facilitates the demoulding of hardware through a shaping mold with a small deformation, does not require an additional ejection mechanism, and prevents the hardware from being damaged by demoulding.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A hardware stamping and shaping device, comprising:

[0008] A lower die base, wherein a lower die plate is provided on the lower die base;

[0009] A deformable forming die for shaping the hardware provided on the lower template;

[0010] An upper die base is correspondingly arranged above the lower die base, comprising an upper die plate installed on the upper die base and movable up and down;

[0011] and a stamping die which is arranged on the upper template and is used for stamping the hardware.

[0012] Furthermore, the deformable molding die comprises:

[0013] A first deformable mold plate close to the hardware;

[0014] a second deformable mold plate located outside the first deformable mold plate;

[0015] a slot located between the first deformable mold plate and the second deformable mold plate;

[0016] and an inserting plate detachably arranged in the slot.

[0017] Furthermore, the deformation of the first deformable mold plate 21 is 0.1-0.5 mm, and the deformation of the second deformable mold plate 22 is 0.05-0.3 mm.

[0018] Furthermore, the deformation direction of the first deformable mold plate 21 is toward the hardware, and the deformation direction of the second deformable mold plate 22 is away from the hardware.

[0019] Furthermore, the thickness of the inserting plate 24 is greater than the thickness of the slot 23 by 0.1-0.3 mm, and the height of the inserting plate 24 is greater than the height of the slot 23 by 0.2-0.5 mm.

[0020] Furthermore, the shape of the space enclosed by the first deformable mold plate 21 for placing the hardware is consistent with the shape of the hardware, and its size is larger than the size of the hardware, by 0.1-0.3 mm.

[0021] Furthermore, the thickness of the first deformable mold plate 21 is 3-5 mm and the height is 10-15 mm;

[0022] The second deformable mold plate 22 has a thickness of 2-4 mm and a height of 10-15 mm.

[0023] Furthermore, a limit plate for limiting the downward pressure of the stamping die is connected to the inserting plate, and the thickness of the limit plate and the height of the inserting plate are adjusted according to the hardware processing requirements.

[0024] Furthermore, a plurality of fixing rods are fixedly mounted on the lower template, and the upper template passes through the fixing rods and can slide up and down along the fixing rods.

[0025] Furthermore, the fixing rods are vertical and distributed at the four top corners of the lower template.

[0028] Furthermore, a driving mechanism is installed on the upper die base, and the driving mechanism is connected to the upper die plate and drives it to move up and down.

[0029] Furthermore, the driving mechanism is a conventional technology in this field. In order to improve the stability and accuracy of the upper template moving up and down, the driving mechanism can adopt a hydraulic drive method, such as a hydraulic cylinder.

[0030] Furthermore, the driving mechanism is connected to the upper template via a connecting member, which may be a connecting structural member commonly used in the art, such as a connecting plate or a flange, and its purpose is only to connect the driving mechanism to the upper template so that the driving mechanism drives the upper template to move up and down.

[0032] Furthermore, a plurality of connection holes for fixing are distributed on both sides of the connection frame, and bolts are screwed into the connection holes to fix the connection frame and the lower mold base.

[0033] Compared with the prior art, the utility model has the following advantages:

[0034] (1) The present invention sets the forming mold as a deformable forming mold, and provides a slot between the first deformable mold plate and the second deformable mold plate, and the insert plate is detachably installed in the slot. During the stamping and forming process of the hardware, the insert plate is inserted into the slot to enhance the structural strength of the deformable forming mold and prevent the deformable forming mold from deforming and causing the hardware stamping and shaping to fail. At this time, the deformable forming mold cannot be deformed, which is consistent with the structural strength of an ordinary forming mold. When the stamping of the hardware is completed again, the insert plate is pulled out of the slot. At this time, the structural strength of the deformable forming mold is weakened, and the first deformable mold plate and the second deformable mold plate are slightly deformed. The hardware can be smoothly removed from the deformable forming mold to achieve demolding without the need for an additional ejection structure, thereby preventing the hardware from being damaged during the demolding process. At the same time, the demolding operation is simplified and the demolding time is reduced.

[0035] (2) In the present invention, the movement trajectory of the upper template is limited by the fixed rod and the sliding sleeve, which can enhance the stability during the movement and prevent the stamping die from shifting during stamping and affecting the processing quality of the hardware.

[0050] Example 1

[0051] A hardware stamping and shaping device, such as Figures 1 to 3 Shown, including:

[0052] A lower die base, on which a lower die plate 1 is provided;

[0053] A deformable forming die 2 for shaping the hardware is provided on the lower template 1;

[0054] An upper die base is correspondingly arranged above the lower die base, including an upper die plate 3 installed on the upper die base and movable up and down;

[0055] And a stamping die 4 is arranged on the upper template 3 and used for stamping the hardware.

[0056] In this embodiment, the deformable molding die 2 includes:

[0057] A first deformable mold plate 21 close to the hardware;

[0058] a second deformable mold plate 22 located outside the first deformable mold plate 21;

[0059] a slot 23 located between the first deformable mold plate 21 and the second deformable mold plate 22;

[0060] And an inserting plate 24 detachably arranged in the slot 23 .

[0061] In this embodiment, the deformation of the first deformable mold plate 21 is 0.1-0.5 mm, and the deformation of the second deformable mold plate 22 is 0.05-0.3 mm.

[0062] In this embodiment, the first deformable die plate 21 is made of a steel alloy, model 45 steel; the second deformable die plate 22 is made of wear-resistant steel, model Cr12; the insert plate 24 is made of high-hardness alloy steel, model SKD11, and is non-deformable. When inserted into the slot 23, it reinforces the structure of the deformable die 2, preventing deformation of the deformable die 2 during the stamping process that could affect the quality of the hardware. The slot 23 is used to reduce the structural strength of the deformable die 2, allowing it to deform during the demolding process of the hardware to facilitate rapid demolding.

[0063] In this embodiment, the deformation direction of the first deformable mold plate 21 is toward the hardware component, and the deformation direction of the second deformable mold plate 22 is away from the hardware component.

[0064] In this embodiment, the thickness of the plug board 24 is 0.2 mm greater than the thickness of the slot 23 , and the height of the plug board 24 is 0.35 mm higher than the height of the slot 23 , so that the plug board can be pulled out smoothly.

[0065] In this embodiment, the shape of the space enclosed by the first deformable mold plate 21 for placing the hardware is consistent with the shape of the hardware, and its size is larger than the size of the hardware by 0.2 mm.

[0066] In this embodiment, the thickness of the first deformable mold plate 21 is 4 mm and the height is 13 mm;

[0067] The second deformable mold plate 22 has a thickness of 3 mm and a height of 13 mm;

[0068] The slot 23 has a thickness of 2.5 mm and a height of 13 mm;

[0069] The inserting plate 24 has a thickness of 2.7 mm and a height of 13.2 mm.

[0070] In this embodiment, a limiting plate 25 is connected to the inserting plate 24 to limit the downward pressing degree of the stamping die 4. The thickness of the limiting plate 25 and the height of the inserting plate 24 are adjusted according to the hardware processing requirements.

[0071] In this embodiment, a plurality of fixing rods 5 are fixedly mounted on the lower template 1, and the upper template 3 passes through the fixing rods 5 and can slide up and down along the fixing rods 5. The fixing rods 5 are vertical and are distributed at the four corners of the lower template 1.

[0072] In this embodiment, four through holes are provided on the upper template 3 for the fixing rods 5 to pass through, and sliding sleeves 31 are installed at the through holes. The sliding sleeves 31 are slidably connected to the fixing rods 5 .

[0073] In this embodiment, the stamping die 4 corresponds to the position of the deformable forming die 2 , and the stamping die 4 is located directly above the deformable forming die 2 .

[0074] In this embodiment, a drive mechanism is mounted on the upper die base, which is connected to the upper die plate 3 and drives it to move up and down. The drive mechanism is conventional in the art. To improve the stability and accuracy of the upper die plate's movement, the drive mechanism can be hydraulically driven, such as by a hydraulic cylinder.

[0075] In this embodiment, the driving mechanism is connected to the upper template 3 via a connecting member 6. The connecting member 6 can be a connecting structural member commonly used in this field, such as a connecting plate. Its purpose is only to connect the driving mechanism to the upper template 3 so that the driving mechanism drives the upper template 3 to move up and down.

[0076] In this embodiment, the lower mold plate 1 and the lower mold base are connected via connecting frames 7, which are symmetrically mounted on both sides of the bottom of the lower mold plate 1. A plurality of connecting holes 71 for fixing are distributed on both sides of the connecting frames 7. Bolts are screwed into the connecting holes 71 to secure the connecting frames 7 to the lower mold base. The connecting holes 71 are evenly spaced.

[0077] The working process and working principle of the stamping shaping device are as follows:

[0078] Insert the insert plate 24 into the slot 23, and place the hardware in the deformable forming mold 2. The hardware is close to the first deformable mold plate 21, and the second deformable mold plate is located on the outside of the hardware and does not contact the hardware. The upper template 3 is driven downward along the fixed rod 5 by the driving mechanism, and then the stamping mold 4 is driven downward to contact the limit plate 25, so that the stamping mold 4 cooperates with the deformable forming mold 2 to stamp the hardware. After the stamping is completed, the upper template 3 is raised by the driving mechanism to raise the stamping mold 4. Remove the insert plate 24, so that the slot 23 in the deformable forming mold 1 is hollow, and the first deformable mold plate 21 and the second deformable mold plate 22 are slightly deformed to quickly remove the stamped and formed hardware. No additional ejection structure is required to prevent damage to the hardware during demolding. When stamping again, the insert plate 24 is inserted into the slot 23 again to ensure the structural strength of the deformable molding die 2 and prevent the deformable molding die 2 from being deformed during the molding process.

[0079] The above description of the embodiments is intended to facilitate understanding and use of the utility model by those skilled in the art. Those skilled in the art will readily be able to make various modifications to these embodiments and apply the general principles described herein to other embodiments without requiring inventive effort. Therefore, the utility model is not limited to the above-described embodiments. Improvements and modifications made by those skilled in the art based on the disclosure of this utility model without departing from the scope of this utility model should be within the scope of protection of this utility model.
