Description

Technical Field

[0001] This application relates to the field of embossing technology, and in particular to an embossing device for workpieces. Background Technology

[0002] Currently, embossing is a process for forming text or patterns on the surface of materials. It mainly involves using pressure to press the shape of text, patterns, etc., on a mold or tool onto the target material. This pressure can change the shape of the material surface. For example, on metal materials, pressure can cause the metal to undergo plastic deformation, thereby permanently leaving the pattern or text on the surface. On some softer materials such as leather and paper, embossing can also create indentations or protrusions on the surface through compression to display the desired text or pattern.

[0003] like Figure 1 The metal workpiece shown is cylindrical, with an opening at one end forming a cavity, and the other end requiring embossing. A notch is also provided on the side wall of the workpiece, connecting to the cavity.

[0004] Regarding the aforementioned technologies, traditional workpiece engraving equipment mainly includes stamping engraving equipment. These engraving devices have the problem of not being able to engrave around the workpiece. In addition, existing equipment requires removing each workpiece after engraving before engraving the next workpiece. This results in frequent loading and unloading operations, high labor intensity, and low processing efficiency, making it difficult to meet the requirements of engraving large batches of workpieces. Therefore, improvements are needed. Utility Model Content

[0005] To facilitate the embossing and engraving of workpieces and improve production efficiency, this application provides a workpiece engraving and embossing device.

[0006] The workpiece engraving and embossing device provided in this application adopts the following technical solution: A workpiece engraving and embossing device includes a base, a support platform, a mold base, positioning pins, a punch head, a letter plate, a driving component, and a pushing assembly. The support platform is horizontally arranged and rotatably connected to the base, with the rotation axis of the support platform along the vertical direction. The mold base is disposed on the support platform and arranged in an array along the circumferential direction. The positioning pins are provided on the mold base and are used to position the workpiece. The stamping head is raised and lowered and located above the mold base. The letter plate is disposed on the stamping head and is used to print letters on the workpiece. The driving component is connected to the stamping head and is used to control the up and down movement of the stamping head. The pusher assembly is located above the support platform and close to the stamping head. The pusher assembly is used to push the workpiece off the letter plate.

[0007] By adopting the above technical solution, during production, the worker first clamps the workpiece onto the positioning post, relying on static friction to position the workpiece. Next, the support platform is rotated, positioning the die holder containing the workpiece directly below the stamping head. Then, the driving mechanism controls the stamping head to press downwards, causing the lettering plate to contact and press against the workpiece, thus completing the embossing process.

[0008] After the engraving is completed, the drive unit controls the stamping head to move upward, using the interference fit of the lettering plate to temporarily pull the workpiece out, that is, to overcome static friction and detach the workpiece from the positioning post. At this time, the pusher assembly is used to push the workpiece off the lettering plate, thus completing the unloading process.

[0009] By setting up multiple sets of mold bases, the workers place the workpieces to be engraved on the positioning columns in sequence. The workpieces on each mold base pass under the stamping head at certain intervals to be imprinted, thus achieving continuous production and improving production efficiency.

[0010] Preferably, the driving component is a press or a hydraulic cylinder, and the support platform is rotated by a stepper motor.

[0011] By adopting the above technical solutions, the press (including punch press and hydraulic press) is a compact and versatile press. It has the characteristics of wide application and high production efficiency. The press can be widely used in processes such as cutting, punching, piercing, blanking, bending, riveting and forming.

[0012] Hydraulic cylinders use hydraulic oil as their working medium, transmitting power through fluid pressure energy. They can generate significant thrust, meeting the demands of stamping processes. Through a hydraulic control system, the cylinder's speed, stroke, and pressure can be precisely adjusted, exhibiting excellent speed regulation and force control performance.

[0013] A stepper motor is an electromagnetic analog-to-digital converter that transforms electrical pulse signals into angular or linear displacement. It has the following characteristics: Precise position control: With each input electrical pulse, the motor rotates by a fixed angle, called the step angle. By controlling the number and frequency of pulses, the rotation angle and speed of the motor can be precisely controlled, achieving rotation control at regular intervals. For example, stepper motors are widely used in positioning and transmission systems in automated equipment requiring precise position control, such as CNC machine tools, 3D printers, and robots.

[0014] Excellent stability: Without losing steps, the stepper motor can maintain precise position and speed, unaffected by load changes. Even at low speeds, it maintains smooth rotation without jitter or jamming.

[0015] Easy to control: The rotation direction, speed, and position of a stepper motor can be easily controlled by providing appropriate pulse signals. Pulse signals can be generated and controlled by computers, microcontrollers, or dedicated drivers to achieve various complex motion control tasks.

[0016] It has a self-locking capability: when the motor stops, it can remain in its current position even without an external braking device, and will not easily rotate due to external force.

[0017] Preferably, it also includes a limiting block, which is close to the positioning post and is used to limit the notch of the workpiece and restrict the rotation of the workpiece on the positioning post.

[0018] By adopting the above technical solution, the limiting block and the positioning column cooperate with each other to further restrict the position of the workpiece and ensure the uniformity of the workpiece position on each mold base.

[0019] Preferably, a guide rod is connected to the stamping head, and a guide groove is correspondingly provided on the die base. When the stamping head presses onto the die base, the guide rod is located in the guide groove.

[0020] By adopting the above technical solution, when the stamping head presses downward, the guide rod moves downward synchronously and gradually extends into the guide groove. The guide rod and the guide groove cooperate with each other to improve the stability of the stamping head's downward press.

[0021] Preferably, the pushing assembly includes a linear cylinder and a flexible block, the flexible block being connected to the piston rod of the linear cylinder, and the flexible block being used to push down the workpiece adhered to the letter plate.

[0022] By adopting the above technical solution, the linear cylinder can control the flexible block to move in the direction close to the letter plate, so that the flexible block contacts and generates a horizontal thrust on the workpiece, thereby pushing the workpiece stuck to the letter plate off and realizing unloading.

[0023] Preferably, the assembly further includes a screw, a mounting block, a first bolt, and a second bolt. The height of the pushing assembly is adjustable. The screw is vertically mounted on the machine base, and the mounting block is attached to the screw. The mounting block has a mounting groove for placing the linear cylinder. The first bolt is located on the mounting block and is used to lock the linear cylinder. The second bolt is located on the mounting block and is used to lock the mounting block onto the screw.

[0024] By adopting the above technical solution, the first bolt locks the linear cylinder onto the mounting block, making the linear cylinder detachable. The second bolt locks the mounting block onto the screw, fixing the linear cylinder by pressure. When the position of the linear cylinder needs to be adjusted, the second bolt can be loosened first, then the mounting block can be moved up and down along the screw to change the height of the linear cylinder. Finally, the second bolt is used to lock it again, allowing workers to easily adjust the height of the pusher assembly according to actual needs, thereby better pushing down the workpiece.

[0025] Preferably, the mold base is detachably connected to the support platform.

[0026] By adopting the above technical solution, the mold base can be replaced when it is damaged. Furthermore, when positioning workpieces of different specifications is required, a mold base with positioning pins of the corresponding specifications can be installed.

[0027] Preferably, the letter plate is detachably connected to the stamping head, the stamping head has a slot, the letter plate is embedded in the slot, and the letter plate is locked to the stamping head by fastening bolts.

[0028] By adopting the above technical solution, the letter plate can be replaced when it is necessary to change the engraving content on the workpiece. The letter plate is embedded in the slot, which can increase the contact area between the workpiece and the stamping head. Then, it is locked by fastening bolts to fix the letter plate.

[0029] In summary, this application includes at least one of the following beneficial technical effects: (1) By setting up multiple sets of mold bases, the workers place the workpieces to be engraved on the positioning columns in sequence for positioning. The workpieces on each mold base pass under the stamping head at certain intervals for stamping, thereby achieving continuous production and improving production efficiency. As for the workpieces that have been engraved, they are temporarily brought out by the rising of the stamping head so that the pusher assembly can push the workpieces off the letter plate, thus completing automatic unloading.

[0030] (2) By setting limit blocks, the limit blocks and positioning columns cooperate with each other to further restrict the position of the workpiece, improve the stability of the workpiece, and at the same time ensure the uniformity of the workpiece position on each mold base.

[0031] (3) By setting the letter plate to be detachable, the letter plate can be replaced when it is necessary to change the engraving content on the workpiece, thereby improving the practicality of production. Attached Figure Description

[0038] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Without conflict, those skilled in the art can combine and integrate the different embodiments or examples shown in this application, as well as the features of those embodiments or examples.

[0039] This application discloses a workpiece engraving and embossing device. (Refer to...) Figures 2 to 4 The lettering and embossing device includes a base 1, a support platform 2, a mold base 3, positioning posts 4, a punch head 5, a letter plate 6, a drive component 7, and a pusher assembly 8. The base 1 serves as a carrier and is fixedly installed on the ground. The support platform 2 is frustum-shaped, horizontally positioned, and rotatably connected to the base 1, with its rotation axis along the vertical direction. In this embodiment, the support platform 2 rotates via a stepper motor. A stepper motor is an electromagnetic analog-to-digital converter that converts electrical pulse signals into angular or linear displacement, featuring precise position control, self-locking capability, and stability. The mold base 3 is mounted on the support platform 2, with multiple mold bases arranged in a circular array. Positioning posts 4 are fixedly connected to the mold base 3, vertically positioned, and used for positioning the workpiece.

[0040] The stamping head 5 is vertically mounted on the machine base 1, positioned above the moving path of each die base 3. A letter plate 6 is mounted on the stamping head 5, facing downwards towards the die base 3; the letter plate 6 is used to print characters on the workpiece. A drive unit 7 is mounted on the machine base 1 and connected to the stamping head 5; the drive unit 7 controls the stamping head 5 to press downwards. In this embodiment, the drive unit 7 is a press or a hydraulic cylinder; both presses and hydraulic cylinders are existing devices that can be used to realize the stamping action of the stamping head 5.

[0041] The pusher assembly 8 is mounted on the machine base 1 and close to the punch head 5. The pusher assembly 8 is used to push down workpieces on the letter plate 6. The pusher assembly 8 consists of a linear cylinder 81 and a flexible block 82. The linear cylinder 81 is horizontally positioned above the support platform 2. The flexible block 82 is connected to the piston rod of the linear cylinder 81 and is used to push down workpieces adhered to the letter plate 6. The flexible block 82 is made of a flexible material, including but not limited to rubber and silicone.

[0042] During production, the worker first clamps the workpiece onto the positioning post 4, relying on static friction to position the workpiece. Next, the support platform 2 is rotated, positioning the die base 3 containing the workpiece directly below the stamping head 5. Then, the driving component 7 controls the stamping head 5 to press downwards, causing the lettering plate 6 to contact and press against the workpiece, thus completing the lettering process.

[0043] After the engraving is completed, the drive unit 7 controls the stamping head 5 to move upward. Using the interference fit of the letter plate 6, the workpiece is temporarily pulled out, that is, the static friction force is overcome to detach the workpiece from the positioning post 4. At this time, the linear cylinder 81 controls the flexible block 82 to push the workpiece off the letter plate 6, realizing the unloading.

[0044] Specifically, a limiting block 9 is fixedly connected to the mold base 3. The limiting block 9 is vertically positioned and close to the positioning post 4. The limiting block 9 is used to limit the notch of the workpiece, restricting the workpiece from circumferential rotation on the positioning post 4. The limiting block 9 and the positioning post 4 cooperate with each other to further restrict the position of the workpiece and ensure the uniformity of the workpiece position on each mold base 3. A guide rod 10 is fixedly connected to the punch head 5. The length direction of the guide rod 10 is parallel to the moving direction of the punch head 5. Two guide rods 10 are arranged in parallel, and two guide grooves 11 are opened at corresponding positions on the mold base 3. When the punch head 5 punches downwards to the mold base 3, the guide rods 10 move downwards synchronously and gradually extend into the guide grooves 11. The guide rods 10 and the guide grooves 11 cooperate with each other to improve the smoothness of the punch head 5's downward punching.

[0045] In this embodiment, the mold base 3 is detachably connected to the support platform 2. The mold base 3 is detachable by means of plug-in or bolt fastening. For example, by plug-in, several plug rods are fixedly connected to the support platform 2, and several plug holes are opened on the mold base 3, into which the plug rods are inserted. When the mold base 3 is damaged, it can be replaced. Furthermore, when it is necessary to position workpieces of different specifications, the mold base 3 can be replaced with a mold base 4 of the corresponding specification.

[0046] The letter plate 6 is also detachably connected to the stamping head 5. The lower end of the stamping head 5 has a slot 12, in which the letter plate 6 is embedded, with the letter face facing the mold base 3. The letter plate 6 is locked to the stamping head 5 by fastening bolts. When it is necessary to change the engraving content on the workpiece, the letter plate 6 can be replaced. The letter plate 6 being embedded in the slot 12 increases the contact area between the workpiece and the stamping head 5, and then is locked in place by fastening bolts, thus fixing the letter plate 6.

[0047] Combination Figure 5 In addition, the base 1 is also equipped with a screw 13, a mounting block 14, a first bolt 15, and a second bolt 16. The screw 13 is vertically fixed to the base 1, and the mounting block 14 is in contact with the screw 13. The mounting block 14 has a mounting groove 17 for placing the linear cylinder 81. The first bolt 15 is screwed onto the mounting block 14, and one end of the first bolt 15 is used to lock the linear cylinder 81 in the mounting groove 17, making the linear cylinder 81 detachable. The second bolt 16 is also screwed onto the mounting block 14. The second bolt 16 and the first bolt 15 are on the same straight line, and the linear cylinder 81 is located between the first bolt 15 and the second bolt 16. One end of the second bolt 16 is used to lock the mounting block 14 onto the screw 13, so that the position of the mounting block 14 relative to the screw 13 is adjustable.

[0048] When the position of the linear cylinder 81 needs to be adjusted, the second bolt 16 can be loosened first, and then the mounting block 14 can be controlled to move up and down along the screw 13 to change the height between the linear cylinder 81 and the support platform 2. After adjustment, the second bolt 16 can be tightened to allow the staff to adjust the height of the entire pusher assembly 8 according to actual needs, so as to push the workpiece down better.

[0049] The implementation principle of the workpiece engraving and stamping device in this application embodiment is as follows: During production, the operator places the workpieces to be engraved on the positioning posts 4 of each mold base 3 for positioning. The workpieces on each mold base 3 pass under the stamping head 5 at certain intervals for engraving, realizing continuous production and improving production efficiency. As for the workpieces after engraving, the rising of the stamping head 5 will temporarily bring the workpiece out so that the pusher assembly 8 can push the workpiece off the letter plate 6, completing automatic unloading.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
