Technical Field

[0001] The utility model relates to the technical field of steel casting manufacturing, in particular to a steel casting punching device. Background Art

[0002] Steel castings refer to steel parts manufactured through a casting process. Steel castings usually have high strength, wear resistance and corrosion resistance. Steel castings include cast steel plates. Cast steel plates can be used in various engineering fields, such as machinery manufacturing, construction engineering, shipbuilding, etc. They are widely used in industrial production and daily life. In the manufacturing process of cast steel plates, punching devices are often used to drill holes in the cast steel plates to facilitate the subsequent assembly of other parts.

[0003] The patent announcement number is CN220093859U, which is a punching device for steel castings. The device includes a workbench, a plurality of limit clamps, and the plurality of limit clamps are arranged on the upper part of the workbench; a hydraulic device, and the hydraulic device is arranged on the workbench; a punching device, and the punching device is connected to the hydraulic device.

[0004] The steel casting punching device with the above-mentioned and similar working principles is prone to the situation that the punching position deviates from the marked position during the punching process. In the actual punching process, in order to improve the quality of punching, it is often necessary to mark the punching position of the steel casting, and then use the punching device to punch the steel casting according to the mark on the steel casting. The steel casting punching device with the above-mentioned and similar working principles does not have the function of auxiliary positioning, which makes it inconvenient for the staff to understand whether the mark and the puncher are in a state of overlap, so that the actual punching position is prone to deviate from the marked position, resulting in an error. Due to the error in opening the hole, the subsequent use of the steel casting may be affected. For this reason, we provide a steel casting punching device. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In the manufacturing process of cast steel plates, a punching device is required. The punching device provided by the utility model is specially used for performing precise punching operations according to the markings on the cast steel plates. When using this device for punching, it is necessary to connect the equipment that needs to be powered in the device to the distribution box in advance, and mark the center point of the marked part without a center point, so as to ensure the normal operation of the equipment's precise punching operation.

[0026] like Figure 1-Figure 6 As shown, the utility model provides a technical solution: a steel casting punching device, comprising a workbench 1, a punching mechanism 5 for punching a cast steel plate is installed on the top of the workbench 1, the punching mechanism 5 comprises a punching head 502, a positioning mechanism 9 for assisting a worker to judge whether the punching head 502 and a marked punching position coincide with each other is installed on the punching head 502, a limiting mechanism 2 for fixing the position of the cast steel plate is installed on the workbench 1, and a through groove 6 adapted to the punching head 502 is opened on the top outer wall of the workbench 1;

[0027] The positioning mechanism 9 includes a mounting hole 901 opened at the end of the punch head 502, and an infrared laser emitter 902 is arranged in the mounting hole 901. The outer wall of the infrared laser emitter 902 is fixedly connected to a hexagonal block 904, and a battery 906 is installed inside the hexagonal block 904. The battery 906 is electrically connected to the infrared laser emitter 902. A threaded rod 905 is fixedly connected to the outer wall of one end of the battery 906. The threaded rod 905 is rotatably inserted into the hexagonal block 904, and multiple outer walls of the hexagonal block 904 are embedded with magnetic sheets 903.

[0028] It should be noted that the infrared laser emitter 902 is located at the center of the mounting hole 901, and the mounting hole 901 is located at the center of the punching head 502. When the cast steel plate needs to be punched, the staff will place the cast steel plate on the table top of the workbench 1, start the infrared laser emitter 902, and the laser emitted by the infrared laser emitter 902 will hit the cast steel plate. According to the laser point emitted by the infrared laser emitter 902, the position of the cast steel plate is adjusted. When the center point of the punching mark on the cast steel plate is adjusted to align with the laser point, the punching operation can be performed. After alignment, the position of the cast steel plate is fixed by starting the limit mechanism 2 to avoid the cast steel plate moving during punching and causing errors in punching. After fixing, the cast steel plate can be punched according to the marked position through the punching mechanism 5. By setting The infrared laser emitter 902 emits a laser, which makes it easy for the staff to intuitively see the relative position relationship between the punch mark and the punch head 502, thereby helping to improve the accuracy and efficiency of punching. Through the hexagonal block 904, in the subsequent maintenance process, by selecting a socket screwdriver compatible with the hexagonal block 904, the socket screwdriver is inserted into the mounting hole 901, and the socket screwdriver is rotated until the threaded rod 905 is removed from the punch head 502, the positioning mechanism 9 can be removed, conversely, the positioning mechanism 9 can be reset, and the positioning mechanism 9 can be installed or removed using the socket screwdriver, which is convenient for the staff to maintain or replace the infrared laser emitter 902. Through the magnetic sheet 903, when installing or removing the positioning mechanism 9, the inner wall of the socket screwdriver sleeve can be adsorbed, so that the positioning mechanism 9 is not easy to slip off.

[0029] like Figure 2 As shown, the stamping mechanism 5 includes a fixed frame 501 installed on the workbench 1, a stamping hydraulic cylinder 504 is installed on the top outer wall of the fixed frame 501, one end of the piston rod of the stamping hydraulic cylinder 504 is fixedly connected to a round block 503, a limiting groove 1001 is opened on the bottom outer wall of the round block 503, a limiting block 507 is inserted in the limiting groove 1001, the top outer wall of the punching head 502 is fixedly connected to the bottom outer wall of the limiting block 507, and a fixing mechanism 10 for locking the position of the limiting block 507 is installed on the round block 503.

[0030] It should be noted that when the stamping mechanism 5 is needed, the stamping hydraulic cylinder 504 is started to drive the round block 503 to move downward, thereby driving the stamping head 502 to move. The punching head 502 moves downward to pass through the cast steel plate to complete the punching. The waste generated by the stamping of the stamping head 502 can be collected through the provided through groove 6, which is conducive to the stamping process.

[0031] like Figure 4 and Figure 5 As shown, the fixing mechanism 10 includes a double-rod hydraulic cylinder 1004 installed on the outer wall of the bottom of the round block 503, one end of the two piston rods of the double-rod hydraulic cylinder 1004 is fixedly connected to a connecting plate 1003, and the connecting plate 1003 is fixedly connected to an insert block 1002, and the outer walls on both sides of the limit block 507 are provided with slots 506 that are compatible with the insert block 1002, and the insert block 1002 is inserted into the slots 506.

[0032] It should be noted that, by means of the limit groove 1001 and the limit block 507, the position of the punch head 502 can be initially fixed so that the punch head 502 will not shake, and by means of the plug block 1002 and the slot 506, the position of the punch head 502 can be further fixed so that the limit block 507 will not fall off from the limit groove 1001. When the punch head 502 needs to be removed, the double-rod hydraulic cylinder 1004 is started to drive the two connecting plates 1003 and the plug block 1002 to move, and the punch head 502 can be removed by moving the plug block 1002 until it leaves the slot 506. The setting of the limit groove 1001, the limit block 507, the double-rod hydraulic cylinder 1004, the connecting plate 1003, the plug block 1002 and the slot 506 can facilitate the staff to quickly disassemble and install the punch head 502, thereby improving the stamping efficiency.

[0033] like Figure 4 As shown in the figure, the limiting mechanism 2 includes two limiting clamps 203, and a screw slide assembly 201 is embedded and installed on the top of the outer wall on one side of the workbench 1 and the top of the outer wall on the other side. The screw slide assembly 201 is installed with a driving motor 202 for driving the screw in the screw slide assembly 201 to rotate. The limiting clamps 203 are installed on the slide part of the screw slide assembly 201, and the two limiting clamps 203 are respectively located at one end of the top of the workbench 1 and the other end of the top.

[0034] It should be noted that when the limiting mechanism 2 needs to be used, the two driving motors 202 are started, and the two limiting clamps 203 are moved through the screw slide assembly 201. When one of the limiting clamps 203 is in contact with the cast steel plate, the driving motor 202 corresponding to the limiting clamp 203 is turned off. When the other limiting clamp 203 is in contact with the cast steel plate, the driving motor 202 corresponding to the limiting clamp 203 is turned off. By having both limiting clamps 203 in contact with the cast steel plate, the position of the cast steel plate can be fixed to avoid errors in punching caused by the movement of the cast steel plate. The design of the two screw slide assemblies 201 is conducive to fixing and limiting the cast steel plate whose punching position is not in the center, which is convenient for use.

[0035] like Figure 1 and Figure 3 As shown, placement grooves 11 are provided at both ends of the top outer wall of the workbench 1, vertical rods 3 are fixedly connected in the placement grooves 11, and the top outer walls of the vertical rods 3 are fixedly connected to the fixing frame 501, and groove blocks 505 slidably sleeved on the vertical rods 3 are fixedly connected at both ends of the outer wall of the round block 503, and a buffer spring 4 is fixedly connected between the bottom outer wall of the groove block 505 and the top outer wall of the placement groove 11, and the buffer spring 4 surrounds the outer wall of the vertical rod 3.

[0036] It should be noted that, by providing the vertical rod 3, the lifting and lowering of the punch head 502 can be made more stable, and by providing the buffer spring 4, the impact force can be buffered and absorbed, which is beneficial to protecting the workpiece and the device.

[0038] It should be noted that the rubber pad 204 can play a buffering role when clamping the cast steel plate, which is beneficial to protecting the cast steel plate. The controller 7 can be used to control the opening or closing of the stamping hydraulic cylinder 504, the infrared laser emitter 902 and the driving motor 202.

[0039] like Figure 3 As shown, a plurality of storage slots are opened on one side outer wall of the workbench 1, and a plurality of detachable collection boxes 8 are inserted into each of the storage slots.

[0040] It should be noted that the collection box 8 can be used to store and place the cast steel plates, and at the same time, the stamping waste dropped from the through groove 6 can be collected, which is conducive to recycling resources.

[0041] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
