[0029] The following further elaborates on the present utility model in conjunction with the attached drawings and specific embodiments.

[0030] In the description of the present utility model, it should be noted that the orientation or positional relationships indicated by the terms "upper", "lower", "left", "right", "inner", "outer", etc. are based on the orientation or positional relationships shown in the attached drawings, or the orientation or positional relationships in which the product of this utility model is habitually placed during use. It is only for the convenience of simplified description, rather than indicating or implying that this orientation is a specific orientation that must be possessed, as well as a specific orientation structure and operation. Therefore, it cannot be understood as a limitation to the present utility model.

[0031] Such as Figures 1 to 4 And Figure 7 And Figure 8As shown in the figure, the utility model relates to a stamping device for metal product letter seals with adjustable height, which includes a frame 1, a height adjustment mechanism 2, a stamping mechanism 3 and a conveyor line 4. The height adjustment mechanism 2 and the conveyor line 4 are both arranged on the frame 1, and the height adjustment mechanism 2 is located above the conveyor line 4. The stamping mechanism 3 is connected to the height adjustment mechanism 2, that is to say, the stamping mechanism 3 is also located above the conveyor line 4. The height adjustment mechanism 2 is used to control the up and down movement of the stamping mechanism 3, so as to change the distance between it and the lower conveyor line 4, so that it can adapt to metal products of different heights. Specifically, the height adjustment mechanism 2 includes a lower baffle 201, an upper baffle 202, a front baffle 203, a motor 204, a transmission component 205, a trapezoidal lead screw 206, a trapezoidal nut 207, a front L-shaped connecting piece 208 and a first guiding component 209. Among them, the lower baffle 201 and the upper baffle 202 are both connected to the frame 1 by screws, so as to be fixed to the frame 1. The motor 204 is arranged at the bottom of the upper baffle 202. There are two mounting holes on the upper baffle 202. The output end of the motor 204 passes through one of the mounting holes and penetrates upward through the upper baffle 202. The trapezoidal lead screw 206 is located on one side of the motor 204 and passes through the other mounting hole of the upper baffle 202. The transmission component 205 connects the output end of the motor 204 and the trapezoidal lead screw 206, so that the motor 204 can transmit power to the trapezoidal lead screw 206 through the transmission component 205 to drive the trapezoidal lead screw 206 to rotate. The trapezoidal nut 207 is threadedly connected to the trapezoidal lead screw 206. The trapezoidal nut 207 will move up and down reciprocally along the trapezoidal lead screw 206 when the lead screw is driven to rotate. The front L-shaped connecting piece 208 is connected to the trapezoidal nut 207 and the front baffle 203. In this way, the front baffle 203 can be driven to move up and down synchronously through the front L-shaped connecting piece 208 during the movement of the trapezoidal nut 207. The first guiding component 209 is arranged between the lower baffle 201 and the upper baffle 202 and is connected to the front baffle 203. The stamping mechanism 3 is arranged on the front baffle 203. The front baffle 203 will move up and down in a straight line under the action of the first guiding component 209 to prevent deviation, ensuring the precise movement of the connected stamping mechanism 3. The stamping device of the utility model uses the conveyor line 4 to convey the metal products to be processed with letter seals and the processed metal products. The metal products to be processed are continuously conveyed by the conveyor line 4 to the lower part of the stamping mechanism 3, and then automatically conveyed away by the conveyor line 4 after processing, which simplifies the steps of manual placement and removal. At the same time, the distance between the stamping mechanism 3 and the conveyor line 4 can be automatically adjusted by driving the height adjustment mechanism 2, so as to meet the stamping requirements of various metal products with different heights, and realize automatic continuous stamping in cooperation with the conveyor line 4. Therefore, it has high production efficiency and low production cost.

[0032] As Figure 4As shown, the transmission assembly 205 includes a front synchronous pulley 205a, a rear synchronous pulley 205b, a synchronous belt 205c, a front expansion sleeve 205d, a front expansion nut 205e, a rear expansion sleeve 205f, and a rear expansion nut 205g. The front expansion sleeve 205d is connected to the front expansion nut 205e. The front synchronous pulley 205a is installed on the trapezoidal lead screw 206 through the front expansion sleeve 205d. The rear expansion sleeve 205f is connected to the rear expansion nut 205g. The rear synchronous pulley 205b is installed on the output end of the motor 204 through the rear expansion sleeve 205f. When the motor 204 operates, its output end first drives the rear synchronous pulley 205b to rotate. The rear synchronous pulley 205b drives the front synchronous pulley 205a to rotate through the synchronous belt 205c. Finally, the power of the motor 204 is transmitted from the front synchronous pulley 205a to the trapezoidal lead screw 206 to make it rotate continuously.

[0033] As Figure 3 shown, the first guiding assembly 209 includes a left sliding bearing 209a, a left guiding shaft 209b, a right sliding bearing 209c, and a right guiding shaft 209d. The left guiding shaft 209b and the right guiding shaft 209d are located on the left and right sides of the front baffle 203. The left sliding bearing 209a and the right sliding bearing 209c are respectively slidably fitted on the left guiding shaft 209b and the right guiding shaft 209d, and both the left sliding bearing 209a and the right sliding bearing 209c are connected to the front baffle 203. When the front baffle 203 moves, the left sliding bearing 209a and the right sliding bearing 209c will respectively move up and down synchronously along the left guiding shaft 209b and the right guiding shaft 209d. Through the guiding action provided by the left guiding shaft 209b and the right guiding shaft 209d, the precise movement of the connected stamping mechanism 3 is ensured. At the same time, the two groups of left sliding bearings 209a, left guiding shafts 209b, right sliding bearings 209c, and right guiding shafts 209d can share the load and improve the smoothness of the movement of the stamping mechanism 3.

[0034] As Figure 5 and Figure 6As shown in the figure, the stamping mechanism 3 includes an upper stamping baffle 301, a lower stamping baffle 302, an upper stamping cross plate 303, a lower stamping cross plate 304, a front stamping baffle 305, a cylinder 306, a rear L-shaped connecting piece 307, a second guiding component 308 and a stamping component 309. Among them, the upper stamping baffle 301 is connected to the upper stamping cross plate 303 by screws, the lower stamping baffle 302 is connected to the lower stamping cross plate 304 by screws, and the upper stamping cross plate 303 and the lower stamping cross plate 304 are connected to the front baffle 203 by screws. In this way, the upper stamping baffle 301 and the lower stamping baffle 302 are respectively placed at the upper and lower ends of the front baffle 203, with a gap between them. The cylinder 306 is arranged at the top of the upper stamping baffle 301. The output end of the cylinder 306 penetrates the upper stamping baffle 301 downward and is simultaneously connected to the rear L-shaped connecting piece 307. The rear L-shaped connecting piece 307 is also connected to the front stamping baffle 305 by screws. The second guiding component 308 is arranged between the upper stamping baffle 301 and the lower stamping baffle 302 and is connected to the front stamping baffle 305. When the cylinder 306 operates, its output end directly controls the high-speed reciprocating up and down movement of the rear L-shaped connecting piece 307. The front stamping baffle is driven by the rear L-shaped connecting piece 307 to move synchronously. The stamping component 309 is arranged on the front stamping baffle 305. The front stamping baffle 305 will move linearly up and down under the action of the second guiding component 308 to prevent deviation, ensuring the precise movement of the connected stamping component 309, so as to successfully stamp out letter steel imprints on the metal products to be processed.

[0035] As Figure 6 shown in the figure, the second guiding component 308 includes a left stamping sliding bearing 308a, a left stamping guiding shaft 308b, a right stamping sliding bearing 308c and a right stamping guiding shaft 308d. The left stamping guiding shaft 308b and the right stamping guiding shaft 308d are located on the left and right sides of the front stamping baffle 305. The left stamping sliding bearing 308a and the right stamping sliding bearing 308c are respectively slidably fitted on the left stamping guiding shaft 308b and the right stamping guiding shaft 308d and are both connected to the front stamping baffle 305. The function of the second guiding component 308 is similar to that of the first guiding component 209. When the front stamping baffle 305 moves, the left stamping bearing and the right stamping bearing will respectively move up and down synchronously along the left stamping guiding shaft 308b and the right stamping guiding shaft 308d. Through the guiding action provided by the left stamping guiding shaft 308b and the right stamping guiding shaft 308d, the precise movement of the connected stamping component 309 is ensured. At the same time, the two groups of left stamping sliding bearings 308a, left stamping guiding shafts 308b, right stamping sliding bearings 308c and right stamping guiding shafts 308d can share the load and improve the smoothness of the movement of the stamping component 309.

[0036] As Figure 5As shown in the figure, the stamping assembly 309 includes a left L-shaped connecting piece 309a, a left stamping head 309b, a right L-shaped connecting piece 309c and a right stamping head 309d. The left L-shaped connecting piece 309a and the right L-shaped connecting piece 309c are located on the left and right sides of the front stamping baffle 305, and are both connected to the front stamping baffle 305 by screws. The left stamping head 309b and the right stamping head 309d are respectively connected to the left L-shaped connecting piece 309a and the right L-shaped connecting piece 309c by screws. The left stamping head 309b and the right stamping head 309d, as the output elements of the stamping mechanism 3, are used to stamp steel seals on the metal products to be processed. The two groups of left stamping heads 309b and right stamping heads 309d have the advantage of parallel operation and can perform stamping operations simultaneously, enabling more metal products to be processed during a single stamping process and reducing the time for a single stamping.

[0037] As Figure 2 As shown in the figure, the frame 1 includes a left column 101, a right column 102, a left baffle 103 and a right baffle 104. The left column 101 and the right column 102 are respectively arranged on the left and right sides of the conveyor line 4. The left baffle 103 and the right baffle 104 are respectively installed on the left column 101 and the right column 102 by screws. The left and right sides of the lower baffle 201 and the upper baffle 202 of the height adjustment mechanism 2 are both connected to the left baffle 103 and the right baffle 104 by screws. Based on the above settings, the height adjustment mechanism 2 can be stably maintained above the conveyor line 4 under the support of the left column 101, the right column 102, the left baffle 103 and the right baffle 104.

[0038] As Figure 2 As shown in the figure, the frame 1 further includes a support base 105. The conveyor line 4 is arranged on the support base 105 and is supported by the support base 105. At the same time, support feet 106 are provided at the bottom of the support base 105. Preferably, the number of support feet 106 is multiple. Through the multiple support feet 106, the support base 105 obtains multiple support points to ensure the stable support of the conveyor line 4.

[0039] As Figure 2 As shown in the figure, the frame 1 further includes a left guard plate 107 and a right guard plate 108. The left guard plate 107 and the right guard plate 108 are both arranged on the support base 105, and the left guard plate 107 and the right guard plate 108 are located on the left and right sides of the conveyor line 4. The left guard plate 107 and the right guard plate 108 establish left and right barriers for the conveyor line 4, thereby preventing the problem that the metal products deviate from the conveyor line 4 due to accidental forces during the process of the conveyor line 4 transporting the metal products, and ensuring the realization of continuous stamping operations.

[0040] Combined with Figures 1 to 8, when the stamping device of the present utility model is operating, the metal product to be processed with a letter embossment is first conveyed to the lower part of the stamping mechanism 3 through the conveyor line 4. At this time, according to the actual height of the metal product, the height adjustment mechanism 2 automatically adjusts the height of the stamping mechanism 3, that is, the motor 204 of the height adjustment mechanism 2 operates to drive the rear synchronous pulley 205b of the transmission assembly 205 to rotate. The rear synchronous pulley 205b drives the front synchronous pulley 205a to rotate through the synchronous belt 205c. Finally, the power of the motor 204 is transmitted from the front synchronous pulley 205a to the trapezoidal lead screw 206 to make it continuously rotate. The trapezoidal nut 207 will move up and down along the trapezoidal lead screw 206, and drive the front baffle 203 to move up and down through the front L-shaped connecting piece 208. The front baffle 203 drives the upper stamping baffle 301, the lower stamping baffle 302, the upper stamping cross plate 303, and the lower stamping cross plate 304 of the stamping mechanism 3 to move. At this time, the cylinder 306 arranged on the upper stamping plate, the rear L-shaped connecting piece 307 connected to the output end of the cylinder 306, the front stamping baffle 305 connected to the rear L-shaped connecting piece 307, and the stamping assembly 309 connected to the front stamping baffle 305 will also move synchronously. After the height adjustment is completed, the cylinder 306 operates, drives the rear L-shaped connecting piece 307 to move up and down through the cylinder 306, and the rear L-shaped connecting piece 307 then drives the front stamping baffle 305 and the stamping assembly 309 to move up and down. The left stamping head 309b and the right stamping head 309d of the stamping assembly 309 will stamp the metal product below, and finally a letter embossment will be formed on the surface of the metal product.

[0041] The above embodiments and descriptions in the specification only illustrate the principle and the best embodiments of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
