Description

Technical Field

[0001] This utility model relates to the field of cold stamping die processing technology, and in particular to a positioning device for cold stamping die processing. Background Technology

[0002] A cold stamping die is a type of mold that applies deformation force to sheet metal placed inside at room temperature. It is a special tool used to obtain product parts with a certain shape, size, and performance by applying deformation force at room temperature on a press. Cold stamping dies are a major tool in modern industrial production and a prerequisite for ensuring the quality of industrial production. In the process of using cold stamping dies, it is necessary to adopt the correct usage methods and carry out effective maintenance.

[0003] Existing patent CN221248547U discloses a positioning device for cold stamping die processing. This utility model describes a device where the upper surface of a placement plate has a moving groove, a fixed plate is positioned at the center of the moving groove, cylinders are symmetrically arranged on both sides of the fixed plate, a sliding plate is slidably disposed inside the moving groove, a connecting block is mounted on the upper surface of the sliding plate, two positioning plates are disposed on the upper surface of the placement plate, and an installation mechanism is disposed on the upper surface of the sliding plate outside the positioning plates. The installation mechanism includes a fixed rod disposed on the upper surface of the sliding plate, and a clamping rod is disposed at the upper end of the fixed rod. By operating the cylinders inside the moving groove, the sliding plate moves within the moving groove, thereby causing the positioning plates on the upper surface of the connecting blocks to move on the placement plate, achieving positioning and clamping of the cold stamping die placed on the placement plate, preventing it from moving and affecting processing.

[0004] However, although the existing patent CN221248547U achieves the positioning and clamping of the cold stamping die placed on the placement plate to prevent it from moving and affecting the processing, the force generated by the extrusion when the device positions and clamps the cold stamping die on the placement plate may damage the surface of the die.

[0005] Therefore, we propose a positioning device for cold stamping die processing. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a positioning device for cold stamping die processing.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A positioning device for cold stamping die processing includes a base, a mounting bracket fixedly disposed on the top of one side of the base, a clamping assembly disposed on one side of the mounting bracket, and a first extrusion cylinder fixedly disposed on one side of the mounting bracket.

[0008] As a further improvement of this utility model: a first hydraulic push rod is provided on one side of the first extrusion cylinder, and a rubber pad is fixedly provided on one side of the first hydraulic push rod. After confirming that the cold stamping equipment is in standby mode, check that the air pressure and hydraulic system pressure of the first extrusion cylinder, the second extrusion cylinder, and the third stamping cylinder are normal (in line with the rated parameters of the equipment), and that there are no foreign objects in the clamping area at the upper end of the base and the mold positioning reference surface is clean and undamaged.

[0009] As a further embodiment of this utility model: a second extrusion cylinder is fixedly installed on one side of the mounting frame, and a second hydraulic push rod is installed on one side of the second extrusion cylinder. The mold to be cold stamped is placed stably on the upper end of the equipment base, ensuring that the clamping side of the mold is aligned with the action surfaces of the first and second hydraulic push rods (to avoid misalignment that could lead to unstable clamping). At the same time, the stamping station of the mold is directly opposite the stamping head below the third stamping cylinder.

[0010] As a further embodiment of this utility model: a rubber pad is fixedly provided on one side of the second hydraulic push rod, and a fixing frame is fixedly provided on the top of the base. The first extrusion cylinder and the second extrusion cylinder are started to drive the corresponding first hydraulic push rod and second hydraulic push rod to move towards each other in the horizontal direction until the end faces of the two push rods are in contact with the outer clamping surface of the mold, thus completing the clamping of the mold.

[0011] As a further embodiment of this utility model: a third stamping cylinder is fixedly installed on one side of the fixing frame, and a stamping head is installed at the bottom of the third stamping cylinder. After confirming that the mold is firmly clamped, the third stamping cylinder is started, and the cylinder drives the stamping head to move downward in the vertical direction, applying pressure to the preset stamping position of the mold to complete the cold stamping forming process.

[0012] As a further embodiment of this utility model: the stamping head is positioned above the base and above the mounting bracket. The clamping ends of the first hydraulic push rod and the second hydraulic push rod are respectively equipped with rubber pad one and rubber pad two. Their function is to buffer the clamping force through their own elasticity, avoid the metal push rod from directly contacting the outside of the mold, and prevent damage such as indentations and scratches from appearing on the mold surface.

[0013] Compared with the prior art, the present invention provides a positioning device for cold stamping die processing, which has the following advantages: This invention, by installing a clamping assembly, allows the mold requiring cold stamping to be placed on the upper end of the base. The first and second extrusion cylinders are activated, driving the first and second hydraulic push rods to move towards each other, clamping the cold stamping mold. The setting of rubber pad one and rubber pad two can prevent the first and second hydraulic push rods from damaging the outer side of the mold. The third stamping cylinder is activated, driving the stamping head downward to stamp the mold on the upper end of the base, effectively improving the safety and practicality of the device.

[0014] This invention involves confirming that the cold stamping equipment is in standby mode, checking that the air and hydraulic system pressures of the first, second, and third extrusion cylinders are normal (meeting the equipment's rated parameters), and ensuring that the clamping area at the top of the base is free of debris and the mold positioning reference surface is clean and undamaged. The mold to be cold-stamped is then placed stably on the top of the equipment base, ensuring that the clamping side of the mold is aligned with the action surfaces of the first and second hydraulic push rods (to avoid misalignment leading to unstable clamping). Simultaneously, the stamping station of the mold is directly opposite the stamping head below the third stamping cylinder. The first and second extrusion cylinders are then activated. The first and second hydraulic push rods are driven to move in opposite directions in the horizontal direction until the end faces of the two push rods are in contact with the outer clamping surface of the mold, thus completing the clamping of the mold. After confirming that the mold is firmly clamped, the third stamping cylinder is activated. The cylinder drives the stamping head to move downward in the vertical direction and apply pressure to the preset stamping position of the mold to complete the cold stamping forming process. The clamping ends of the first and second hydraulic push rods are respectively equipped with rubber pad one and rubber pad two. Their function is to buffer the clamping force through their own elasticity, avoid the metal push rods from directly contacting the outer side of the mold, and prevent damage such as indentations and scratches on the mold surface.
