Description

Technical Field

[0001] The utility model relates to the technical field of industrial letter pressing structures, and particularly relates to a quick replacement structure for the letter head of letter pressing. Background Art

[0002] Industrial letter pressing mainly involves the use of various mechanical equipment and technologies to emboss characters or patterns on the surface of products during the industrial production process to achieve the purposes of identification, decoration, or enhancement of product functions. In practice, when information such as the furnace number of raw materials, production batch number, production date, etc. changes, it is necessary to replace the letter head.

[0003] Traditional letter pressing uses an up-and-down pressing method, and the letter head steel stamp uses a circular pressing cover for fixation. As shown in Figure 2 As shown, the letter head steel stamp is fixed with a cylindrical pressing cover, and the cylindrical pressing cover directly contacts the upper die seat surface of the trimming die. After each batch of products is forged, when replacing the new letter head steel stamp, it is necessary to remove the entire upper die seat, then remove the upper die fixing bolts, and then remove the cylindrical pressing cover to replace the letter head steel stamp. During the reinstallation of the die, it is necessary to repeat the above steps in reverse order to complete the replacement of the letter head steel stamp. This structure is too cumbersome during the process of replacing the letter head and is not conducive to improving the forging production capacity. Content of the Utility Model

[0004] To solve the above problems, the utility model provides a quick replacement structure for the letter head of letter pressing, and the specific technical solution is as follows:

[0005] It includes an upper die fixing plate, a correcting upper die, a fixing part, and a letter head;

[0006] The upper die fixing plate fixes the pressing cover above the correcting upper die. The letter head penetrates and is embedded in the correcting upper die, and one side for letter pressing protrudes below the correcting upper die;

[0007] A fixing groove that penetrates the correcting upper die is formed between the upper die fixing plate and the correcting upper die at the position of the letter head. The fixing part is placed in the fixing groove, and the upper die fixing plate presses on the top of the letter head.

[0008] Further, through holes are provided on the upper die fixing plate, and the upper die fixing plate is fixed and pressed on the correcting upper die by passing upper die fastening bolts through the through holes.

[0009] Further, a through notch is provided at the top of the correcting upper die, and the notch forms a fixing groove that penetrates the correcting upper die between the upper die fixing plate and the correcting upper die.

[0010] Further, the fixing groove penetrates the correcting upper die perpendicular to the axial direction of the letter head.

[0011] Further, when the fixing member is placed between the upper die fixing plate and the upper die for calibration, on the side of the character head for stamping, the main body of the character head is flush with the bottom of the upper die for calibration, and the embossed characters at the bottom of the character head protrude from the bottom of the upper die for calibration.

[0012] Further, the fixing member includes a first fixing pin and a second fixing pin. Both the first fixing pin and the second fixing pin are wedge-shaped structures. The structure formed by the opposite fitting of the wedge-shaped surfaces of the first fixing pin and the second fixing pin is adapted to fill the fixing groove at the top of the character head.

[0013] Further, the first fixing pin and the second fixing pin have the same wedge-shaped structure of a right trapezoidal cube. After the wedge-shaped surfaces of the first fixing pin and the second fixing pin are oppositely fitted, a rectangular cube structure is formed.

[0014] Further, the fixing groove includes a first through groove and a second through groove. The cross-sectional dimension of the second through groove is larger than that of the first through groove, and the character head is placed below the second through groove.

[0015] Further, the wedge-shaped surface formed by the first fixing pin and the second fixing pin is inclined downward from the inside to the outside along the fixing groove.

[0016] Further, for the fixing pin close to one side of the top of the character head, the end with the larger cross-sectional dimension has a height not lower than the height difference between the first through groove and the second through groove.

[0017] The beneficial effects of the present utility model are as follows:

[0018] By improving the fastening structure of the character head, the covering and replacement methods of the character head are improved. Through the through fixing groove formed between the upper die fixing plate and the upper die for calibration, two adapted fixing pins are pushed into the fixing groove to fill the space above the character head to achieve self-locking, and then the character head is embedded in the upper die for calibration. By knocking the upper fixing pin at the other end of the fixing groove, the two fixing pins are separated, and then the character head is taken out for replacement. Compared with the traditional structure, when replacing the new character head steel stamp after forging each batch of products, there is no need to remove the entire upper die seat, and the rapid replacement of the character head can be completed, improving the production efficiency.

[0047] As a preferred embodiment, a through notch is provided at the top of the correcting upper die 2, and the notch forms a fixing groove penetrating through the correcting upper die 2 between the upper die fixing plate 1 and the correcting upper die 2.

[0048] Based on this structure, when the upper die fixing plate 1 and the correcting upper die 2 are not fixedly assembled, the character head 5 can be placed into the correcting upper die 2 through the open notch at the top of the correcting upper die 2.

[0049] As a preferred embodiment, the fixing groove penetrates through the correcting upper die 2 perpendicular to the axial direction of the character head 5.

[0050] Specifically, the penetrating direction of the fixing groove is perpendicular to the adjacent surface of the contact surface between the correcting upper die 2 and the upper die fixing plate 1, that is, relative to the positive direction of the character head 5, it transversely penetrates through the correcting upper die 2.

[0051] As a preferred embodiment, when the fixing member is placed between the upper die fixing plate 1 and the correcting upper die 2, on the embossing side of the character head 5, the main body of the character head 5 is flush with the bottom of the correcting upper die 2, and the raised characters at the bottom of the character head 5 protrude from the bottom of the correcting upper die 2.

[0052] As a preferred embodiment, the fixing member includes a first fixing pin 6 and a second fixing pin 7. Both the first fixing pin 6 and the second fixing pin 7 are wedge-shaped structures. The structure formed by the opposite and fitting wedge surfaces of the first fixing pin 6 and the second fixing pin 7 is adapted to fill the fixing groove at the top of the character head 5.

[0053] In this embodiment, the fixing pin close to the top of the character head 5 is denoted as the second fixing pin 7, and the fixing pin close to the upper die fixing plate 1 is denoted as the first fixing pin 6.

[0054] By successively placing two fixing pins and utilizing the mutual force between the two fixing pins, the fixing groove is gradually filled, and then the character head 5 is fixed in the correcting upper die 2. At the same time, when the character head 5 is replaced, the two fixing pins are separated by using the wedge surfaces in contact with each other, and are successively withdrawn from the fixing groove to realize the removal of the character head 5.

[0055] As a preferred embodiment, the first fixing pin 6 and the second fixing pin 7 have the same wedge-shaped structure of a right trapezoidal cube. After the wedge surfaces of the first fixing pin 6 and the second fixing pin 7 are opposite and fitted, a rectangular cube structure is formed.

[0056] As a preferred embodiment, the fixing groove includes a first through groove 3 and a second through groove 4. The cross-sectional dimension of the second through groove 4 is larger than that of the first through groove 3, and the character head 5 is placed below the second through groove 4.

[0057] Specifically, the top groove surface of the first through groove 3 is flush-connected with the top groove surface of the second through groove 4.

[0058] Through the fixing grooves with two different cross-sectional dimensions, while the character head 5 is fixed and embedded by the fixing member, the communication range between the fixing groove and the outside is reduced, and the pollution of the inside of the groove by the actual environment is reduced.

[0059] Specifically, at the open end of the second through groove 4, the second fixing pin 7 has its wedge surface facing upward, that is, the wedge surface faces the side of the upper die fixing plate 1, and is pushed into the second through groove 4 until the bottom surface completely covers the top of the character head 5. Then, at the open end of the second through groove 4, the first fixing pin 6 has its wedge surface facing downward, that is, in a direction that can be adapted to the second fixing pin 7 to form a rectangular cube structure, and is pushed into the second through groove 4. By knocking the tail end, the longitudinal space of the fixing groove is gradually filled by the sliding of the wedge surfaces of the two fixing pins, so that the character head 5 is fastened within the correcting upper die 2 by the longitudinal pressure generated by the fixing pins, and at the same time, self-locking is realized by the mutual frictional force between the two fixing pins to ensure the stable embedding of the character head 5.

[0060] As a preferred embodiment, the wedge surface formed by the first fixing pin 6 and the second fixing pin 7 has a downwardly inclined structure along the fixing groove from inside to outside.

[0061] Due to the inclined structure of the wedge surface formed by the two fixing pins, when placing the fixing pins into the fixing groove to fasten the type head 5, it is convenient to push the first fixing pin 6 in. At the same time, when replacing the type head 5, by knocking on the first fixing pin 6 at the open end of the first through groove 3, the two fixing pins can be quickly separated, realizing the quick removal and replacement of the type head 5.

[0062] As a preferred embodiment, for the fixing pin close to one side of the top of the type head 5, the end with a larger cross-sectional dimension has a height not lower than the height difference between the first through groove 3 and the second through groove 4, that is, the end of the second fixing pin 7 extending into the second through groove 4 slightly protrudes to the bottom side of the first through groove 3, so that after separating the two fixing pins, it is convenient to push out the second fixing pin 7 remaining in the second through groove 4.

[0063] Based on the above structure, by applying an external force to the fixing pins at the open ends of the second through groove 4 and the first through groove 3, the self-locking fastening and separation withdrawal between the two fixing pins are realized, and the quick replacement of the type head 5 is completed. In a specific implementation, the whole process only takes 5 - 8 minutes to complete one replacement of the type head 5. Compared with the traditional circular gland fixing structure, the time consumption for replacing the type head 5 is reduced by 120 - 150 minutes, and the replacement efficiency of the type head 5 is significantly improved.

[0064] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
