Description

Technical Field

[0001] The present application relates to the field of stamping technology, and in particular to a clamp stamping tool. Background Art

[0002] Stamping is a production technology that uses the power of conventional or special stamping equipment to directly subject the sheet metal to deformation force in the die and deform it, thereby obtaining product parts with certain shapes, sizes and performances. Hoops are generally produced by stamping, that is, the steel bars are placed on the stamping device, and then the upper die moves to squeeze the lower die to stamp into a circular curved shape.

[0003] When producing clamps, the steel bars are usually placed directly on the lower die. In this way, when the upper die is pressed and formed, the clamps are prone to move or even fly out, which may lead to stamping failure and waste of materials. The flying materials to be punched may cause harm to workers, which is very dangerous. Therefore, a clamp stamping tool with strong stability, good safety and high production efficiency is proposed.

[0018] Next, in combination with the specific embodiments, the present application will be further described. It should be noted that on the premise of non-conflict, the following-described embodiments or technical features can be arbitrarily combined with each other to form new embodiments.

[0019] In the description of the present application, it should be noted that for the orientation terms, if there are terms such as "center", "transverse", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation and position relationship are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific protection scope of the present application.

[0020] It should be noted that the terms "first", "second", etc. in the specification and claims of this application are used to distinguish similar objects and do not necessarily describe a specific order or sequence.

[0021] The terms "comprising" and "having" in the specification and claims of this application, and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that comprises a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products, or devices.

[0022] One preferred embodiment of this application is, for example, Figures 1 to 4 As shown, a hoop stamping tooling includes a mounting base 1; at both ends of the mounting base 1, die brackets 11 for mounting dies 2 are symmetrically arranged. Forming grooves 12 for forming and limiting the hoop body are provided on the adjacent opposite side parts of the two die brackets 11. A stamping part 13 is arranged at the upper end of the mounting base 1, and a punch 3 for stamping and forming is arranged at the output end of the stamping part 13; when stamping, the workpiece can be placed on the two dies 2 at this time. When the stamping part 13 operates, it can drive the punch 3 to move downward to contact and extrude the workpiece. During extrusion, the workpiece will stably move downward and be stamped into the two die brackets 11 under the relative rotation of the two dies 2. Then the punch 3 continues to move downward to extrude the workpiece, and the bent workpiece is limited and extruded in the forming grooves 12 on the opposite side parts of the two die brackets 11 to form a finished hoop body, thereby making the overall device have strong stability, good safety, and high production efficiency.

[0023] In this embodiment, for example, Figures 1 to 4 As shown, it should be known that in order to better bend and form the workpiece and carry out production and processing more safely, the die bracket 11 is provided with a triangular section and a vertical section. The bottom of the triangular section is installed at the top of the mounting base 1, the bottom of the vertical section is installed at the upper end of the triangular section, a vertical groove is provided on the side of the vertical section, and an inclined groove is provided on the side of the triangular section. The vertical groove and the inclined groove are connected to form the forming groove 12; when stamping and forming, the workpiece first moves into the vertical groove of the vertical section under the extrusion of the punch 3, and then the vertical groove can limit the workpiece to prevent the workpiece from moving or flying out during extrusion and causing harm to personnel. Subsequently, the punch 3 continues to move downward to extrude, so that the bent workpiece enters the inclined groove from the vertical groove for forming, thereby facilitating better ensuring the safety of the workpiece from the original part to the formed part.

[0024] It can be understood that, for example, Figure 3 and Figure 4As shown in the figure, in order to make the processing of workpieces more secure and stable, a groove is provided at the middle end of the female die 2, so that the workpiece is placed in the groove of the female die 2. During stamping, the workpiece can be more stably moved downward with the male die 3 under the limitation of the grooves of the two female dies 2 to form a shape.

[0025] In this embodiment, as Figures 1 to 3 shown, it can be understood that in order to produce hoop products of different sizes, a plurality of mounting holes 111 are provided on the side of the female die support 11, and the female die 2 can be installed in the mounting holes 111 at different positions to stamp and form hoops of different sizes, which has strong practicability.

[0026] In this embodiment, as Figures 1 to 4 shown, it can be understood that the stamping side of the male die 3 is arc-shaped, so that the workpiece can be bent and extruded. At the same time, in order to make the workpiece move downward more stably without deflection, an arc-shaped groove is provided in the arc section of the male die 3, and the arc-shaped groove matches the workpiece; during stamping, the male die 3 moves downward to contact the workpiece, and then the workpiece enters the arc-shaped groove, which is convenient for the workpiece to have a certain stability and safety during bending stamping.

[0027] It can be understood that, as Figures 2 to 4 shown, the side of the female die 2 can protrude from or be lower than the forming groove 12 of the female die support 11. When the workpiece is placed on the protruding female die 2, when the male die 3 moves downward to drive the workpiece to bend and form, the workpiece can be limited and fixed by the arc-shaped groove on the male die 3, and the groove on the female die 2 can also limit the workpiece; when the side of the female die 2 does not protrude from the forming groove 12, the workpiece is limited and bent and extruded by the forming groove 12 and the arc-shaped groove on the male die 3 together when moving downward and bending.

[0028] In this embodiment, as Figure 1 and Figure 2 shown, the other side of the male die 3 for stamping is horizontally arranged, and a pair of fixing plates are symmetrically arranged at the upper end of the horizontal section of the male die 3, and a plurality of fixing grooves are provided on the side of the fixing plates, so as to better install the stamping part 13 and improve the practicability of the device.

[0029] It can be understood that the stamping part 13 is a common driving device such as a hydraulic press, a hydraulic cylinder, an electric telescopic rod, etc. Those skilled in the art can select a suitable driving device for driving according to the actual situation. The stamping part 13 in this application is a hydraulic press, and the punch of the hydraulic press is connected to the top end of the male die 3.

[0030] In this embodiment, as Figure 1 、 Figure 3 and Figure 4As shown, it should be noted that in order to better form the hoop and make the quality and accuracy of the hoop better after production, an avoidance groove is provided on the side of the mounting seat 1, and the avoidance groove is directly below the punch 3. Therefore, when the stamping part 13 moves downward with the punch 3, the workpiece extends into the arc groove at the bottom arc section of the punch 3. Then, both ends of the workpiece move downward between the two die holders 11 under the relative rotation of the two dies 2. When the punch 3 moves downward for stamping, the two ends of the workpiece can slide into the forming groove 12 of the die holder 11 until the punch 3 bends the workpiece to the limit, that is, the punch 3 moves downward into the avoidance groove, causing the workpiece to be bent into a formed hoop.

[0031] In this embodiment, as Figures 1 to 3 shown, it should be noted that in order to make the two ends of the hoop consistent after bending, a fixed-length plate 4 is provided on the side of at least one die holder 11. A baffle is provided at one end of the fixed-length plate 4. One end of the workpiece can be placed on the tops of the two dies 2, and one end of the workpiece abuts against the baffle on the fixed-length plate 4. At this time, the middle end of the workpiece just matches the middle end of the punch 3, thereby improving the quality of the formed hoop.

[0032] The above describes the basic principles, main features, and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present application. Without departing from the spirit and scope of the present application, the present application will have various changes and improvements, and these changes and improvements all fall within the scope of the present application claimed.
