TECHNICAL FIELD

[0001] The utility model relates to the technical field of letter pressing device, specifically relates to a multi-station integrated letter pressing device for fixed lever. BACKGROUND

[0002] The fixed lever is a key component of the air control system of railway freight cars, as shown in the accompanying drawing, the fixed lever is a thick die forging with arc structure at both ends and a thickness of 25mm. In view of the importance of the fixed lever in the air control system of railway freight cars, the traceability of the forging process is strictly required. Therefore, specific stamp marks need to be stamped on three different positions in the middle of the forging to accurately trace the information of the forging process. Figure 1 The traditional processing method is shown in the accompanying drawing, first, an operator places the workpiece 1 on the letter pressing machine 4 and adjusts the workpiece to ensure that the part to be pressed is accurately located below the pressing head 3. At the same time, another operator selects the corresponding letter head 2 and then places it on the workpiece 1. After preparation, start the letter pressing machine, and the pressing head presses the letter head into the workpiece to complete the pressing of the first position. After completion, the operator removes the used letter head, and another operator adjusts the workpiece to the next position to be pressed. Then, the operator selects and places the letter head again, and repeats the operation of starting the letter pressing machine, and so on until the letter pressing work is completed.

[0003] Figure 2 However, the above method for letter pressing operation has the following problems:

[0004] 1. Since the operator needs to place the workpiece continuously for multiple times, and only relies on visual positioning, the stability of the workpiece position is poor, which easily leads to workpiece letter head deviation.

[0005] 2. The operator needs to select and place the letter head for three times, which is not only cumbersome, but also easy to place the letter head incorrectly due to negligence. At the same time, when placing the letter head, it also relies on visual positioning, and due to the lack of accurate positioning means, the letter head is easy to be placed incorrectly or reversely, which eventually leads to letter head deviation and quality problems.

[0006] 3. When placing the letter head, the operator needs to stretch his hand directly below the pressing head, which has the safety hazard of being pressed.

[0007] 4. The processing method requires at least two operators to cooperate to complete the letter pressing operation, which has low processing efficiency, affects the production progress, and has high labor cost.

[0008] Therefore, in order to solve the problems of low efficiency, unstable quality, high labor intensity and safety hazards of the existing letter pressing method, it is necessary to provide a multi-station integrated letter pressing device for fixed lever.

[0009] Therefore, in order to solve the problems of low efficiency, unstable quality, high labor intensity and safety hazards of the existing letter pressing method, it is necessary to provide a multi-station integrated letter pressing device for fixed lever. ​Utility Model Content

Detailed Implementation

[0036] The following detailed description illustrates the specific implementation method:

[0037] Example 1

[0038] This embodiment is basically as shown in the appendix. Figure 3 As shown: A multi-station integrated lettering device for fixing levers. Positioning blocks are directly set on the main board to limit the workpiece, improving the stability of the lettering position. A letter head box positions and restricts the letter head, preventing misalignment and quality issues. Automatic letter head switching is achieved through a shift slider box, reducing repetitive operations, improving efficiency, and minimizing safety hazards. Specifically, the lettering device is installed inside the lettering machine 4, including a main board 5 with a rectangular structure. In this embodiment, the main board 5 is a 20mm thick steel plate to ensure it can withstand the pressure of the lettering machine without deformation, ensuring the stability and accuracy of the workpiece 1.

[0039] As attached Figure 4 As shown, waist-shaped grooves 25 are provided at both ends of the main board 5. The main board 5 is fixedly installed on the worktable of the printing machine by bolts through the waist-shaped grooves 25 to ensure the stability of the main board 5 during the printing process and to avoid displacement.

[0040] Multiple positioning blocks for positioning workpiece 1 are fixedly mounted on the motherboard 5. In this embodiment, the positioning blocks include a lower positioning block 21 at the lower part of the motherboard 5, an upper positioning block 20 and a second positioning block 22 at the middle part of the motherboard 5, and a left positioning block 19 and a right positioning block 23 at the upper part of the motherboard 5. The upper positioning block 20 and the lower positioning block 21 can quickly determine the first position of workpiece 1 and limit its placement; the upper positioning block 20 and the second positioning block 22 can quickly determine the second position of workpiece 1 and limit its placement; the left positioning block 19 and the right positioning block 23 can quickly determine the third position of workpiece 1 and limit its placement, thus ensuring the stability and accuracy of workpiece 1, avoiding offset or misalignment, improving the stability of workpiece 1, and guaranteeing processing quality.

[0041] Meanwhile, a third screw hole 24 is provided at the upper end of the main board 5 for fixing the connecting block 8 with bolts. This allows one end of the connecting block 8 to be mounted on the main board 5 and the other end to be mounted on the letterbox 6.

[0042] Combined with appendix Figure 5 As shown, a letterpress box 6 is positioned above the mainboard 5. Four second screw holes 16 are provided at one end of the letterpress box 6 for fixed connection with the connecting block 8. Multiple letterpress slots 13 are provided in the middle of the letterpress box 6, and letterpresses 2 for embossing are placed within the slots 13. In this embodiment, three letterpress slots 13 are provided according to processing requirements, arranged side-by-side. Of course, the number of letterpress slots 13 can be adjusted according to requirements, such as four or six.

[0043] In this embodiment, the letterhead slot 13 is configured as a T-shaped structure, allowing the letterhead 2 placed inside the letterhead slot 13 to be secured within it without falling out. Simultaneously, in this embodiment, the letterhead 2 is configured with a T-shaped structure matching the letterhead slot 13, with its lower end extending beyond the bottom of the letterhead slot 13, allowing it to make contact with the surface of the workpiece 1 under pressure to complete the embossing operation. Multiple mounting holes 15 are provided on both sides of the letterhead slot 13, i.e., on the movable plates on both sides of the letterhead slot 13, in conjunction with the attached... Figure 3 As shown, multiple letterhead springs 12 are provided in the mounting hole 15 for resetting the letterhead 2. After the pressure is released, the letterhead springs 12 rebound, causing the movable plates on both sides of the letterhead groove 13 to rebound, so that the letterhead 2 can automatically return to the initial state under the restoring force of the letterhead springs 12, thus achieving automatic return.

[0044] On the letterpress box 6, at both ends of the outer side of the letterpress slot 13, there are also multiple first screw holes 14. The shift slider box 7 is installed on the first screw holes 14 by movable screws, so that the shift slider box 7 is located above the letterpress box 6. (See attached diagram)Figure 3 As shown, a slider spring 11 for resetting the shift slider box 7 is sleeved on the movable screw. When the pressure is removed, the shift slider box 7 returns to its initial state under the action of the slider spring 11, realizing automatic return.

[0045] As attached Figure 6 As shown, a T-shaped groove is provided inside the shift slider box 7, allowing the T-shaped groove to be positioned above the letter slot 13. A shift slider 9, capable of sliding along the T-shaped groove, is installed within the T-shaped groove. (See attached diagram.) Figure 7 As shown, the shift slider 9 has a T-shaped structure that matches the T-shaped groove, allowing its upper end to engage with the T-shaped groove and slide along it. The lower end of the shift slider 9 extends out of the T-shaped groove and can make contact with the lower letterhead 2, pressing the designated letterhead 2 onto the workpiece 1 to complete the imprinting operation. A handle 10 is fixedly installed at one end of the shift slider 9, allowing it to be pulled and slid within the T-shaped groove to move above the designated letterhead 2.

[0046] A through hole 17 is provided at the end of the shift slider box 7. The handle 10 extends through the through hole 17 to the outside of the shift slider box 7, making it easier to operate by hand. The operator only needs to pull the handle 10 to switch gears, ensuring operational safety. Multiple mounting countersunk holes 18 are also provided on both sides of the shift slider box 7. The movable screw is movably set in the mounting countersunk hole 18, limiting the movable screw. Under the force of the slider spring 11, the shift slider box 7 moves up and down along the movable screw, thereby achieving pressing down and resetting.

[0047] The specific implementation process is as follows:

[0048] As attached Figure 8 As shown, when the pressing process of position 1 is required, workpiece 1 is pushed into the main board 5, so that the lower end of workpiece 1 is placed above the lower positioning block 21 of position 1 and the upper end of workpiece 1 is placed below the upper positioning block 20 of position 1, so as to realize the rapid positioning and placement of workpiece 1 in position 1 and ensure the accuracy and stability of the placement.

[0049] Pull the handle 10 outward so that the shift slider 9 is in the position shown in the attached diagram. Figure 8 The first position shown is the first gear position.

[0050] Press the button on the typesetting machine to operate it, causing the pressure head 3 to move downwards and press down. At this time, the pressure of the typesetting machine is transmitted sequentially through the pressure head, the shift slider 9, and the typeface 2 to the surface of the workpiece 1, thus completing the imprinting operation of position 1. After imprinting is completed, the pressure head 3 retracts, and the shift slider box 7 moves upwards to reset under the restoring force of the slider spring 11. The typeface 2 corresponding to position 1 automatically resets under the restoring force of the typeface spring 12.

[0051] As attachedFigure 9 As shown, the second position will be imprinted at this time. The workpiece 1 is moved to the main board 5 so that the two ends of the workpiece 1 are close to the positioning block 20 at the first position and the positioning block 22 at the second position, so as to achieve precise positioning and fixation of the workpiece 1.

[0052] At this time, push the handle 10 inward so that the handle 10 is in the position shown. Figure 9 In position two, press the typesetting machine button to operate the typesetting machine, causing the pressure head 3 to move downwards and press down. At this time, the pressure of the typesetting machine is transmitted sequentially through the pressure head, the shift slider 9, and the typeface 2 to the surface of the workpiece 1, thus completing the typesetting operation in position two. After the typesetting is completed, the pressure head 3 retracts, and the shift slider box 7 moves upwards to reset under the restoring force of the slider spring 11. The typeface 2 corresponding to position two automatically resets under the restoring force of the typeface spring 12.

[0053] As attached Figure 10 As shown, the imprinting of position 3 will be performed at this time. Workpiece 1 will be moved onto the main board 5, so that both ends of workpiece 1 will be close to the left positioning block 19 and the right positioning block 23 of position 3 respectively, so as to achieve precise positioning and fixation of workpiece 1.

[0054] At this point, push the handle 10 inward again, so that the handle 10 is in the position shown. Figure 10 As shown in position three, press the typesetting machine button to operate the typesetting machine, causing the pressure head 3 to move downwards and press down. At this time, the pressure of the typesetting machine is transmitted sequentially through the pressure head, the shift slider 9, and the typeface 2 to the surface of the workpiece 1, thus completing the typesetting operation at position three. After the typesetting is completed, the pressure head 3 retracts, and the shift slider box 7 moves upwards to reset under the restoring force of the slider spring 11. The typeface 2 corresponding to position three automatically resets under the restoring force of the typeface spring 12, completing the typesetting process. This achieves a rapid typesetting operation with multiple positions in one operation.

[0055] In this embodiment, positioning blocks are directly set on the mainboard 5, with each station corresponding to a specific positioning block position. When workpiece 1 is placed, the positioning block can accurately hold the workpiece, effectively restricting its position and ensuring more precise placement, greatly improving the stability of the pressing position and thus enhancing the pressing quality. Simultaneously, the design of the letterhead box 6 features a reasonable internal space layout, allowing for the neat placement of multiple different letterheads. Each letterhead has a corresponding locking position, ensuring accurate positioning and preventing quality accidents caused by misaligned or incorrectly placed letterheads. Furthermore, the shift slider box, with its intuitive markings and convenient operating handle, allows operators to quickly and accurately select and position the required letterhead with simple operation. This not only saves time in selecting and placing letterheads but also significantly reduces the physical exertion from repeated operations, greatly improving work efficiency and reducing worker labor intensity. Moreover, the integrated multi-station letterhead pressing operation can be achieved through simple external operation, avoiding potential safety risks and providing reliable safety guarantees for operators.

[0056] The above descriptions are merely embodiments of this utility model. Commonly known technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
