Description

Technical Field

[0001] This utility model relates to the field of metal casting processing technology, and specifically to a punching device for metal casting processing. Background Technology

[0002] Castings are metal shaped objects obtained by various casting methods. That is, smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods. After cooling, it is processed by subsequent means such as grinding to obtain an object with a certain shape, size and performance. After the metal casting is formed, it is often necessary to punch holes on its surface according to different uses.

[0003] Application No. CN202320603914.1 discloses a punching device for metal casting processing, including a frame, a hydraulic cylinder, and a pressure ring. Support plates are fixedly provided on both sides of the bottom end of the frame, and a first baffle is fixedly provided on one side of the bottom end of the frame. A guide plate is fixedly provided at the bottom end of the first baffle. A hydraulic cylinder is fixedly provided in the middle of the top end of the frame, and a lifting plate is fixedly connected to the hydraulic rod of the hydraulic cylinder. This utility model controls the retraction of the hydraulic rod of the hydraulic cylinder, and the hydraulic rod of the hydraulic cylinder can lift the pressure ring through the lifting plate, so that the operator can place the metal casting to be punched at the bottom end of the pressure ring. By controlling the extension of the hydraulic rod of the hydraulic cylinder, the pressure ring can press the metal casting under the pressure of the compression spring.

[0004] However, the device lacks a positioning device during use, which means that when punching multiple castings of the same model, the uncertainty of manually placing the castings makes it impossible to guarantee that the punching of each casting is in the same position. Therefore, a punching device for metal casting processing is proposed. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides a punching device for metal casting processing.

[0006] The technical solution adopted by this utility model to solve its technical problem is a punching device for metal casting processing, including a mounting box and a push plate. The mounting box has an operating cavity inside, and the push plate is movably installed inside the operating cavity. The bottom of the operating cavity has a first sliding groove. There are two first sliding grooves, and the two first sliding grooves are used for sliding installation of a second slider. The second slider is fixedly connected to the bottom end of the push plate.

[0007] A positive abutment plate is fixedly connected to the lower part of one side of the push plate. A second sliding groove is provided inside the positive abutment plate, and the interior of the second sliding groove is used for the sliding installation of the side abutment plate.

[0008] By adopting the above technical solution, the combination of the front abutment plate and the side abutment plate can provide a positioning effect for the placement of metal castings. Castings of the same model only need to be close to the front abutment plate and the side abutment plate to achieve punching positioning, which can make the punching position of metal castings of the same model consistent.

[0009] Specifically, an electric cylinder is fixedly installed on one side of the mounting box, and the output end of the electric cylinder is fixedly connected to the center of one side of the push plate.

[0010] By adopting the above technical solution, the electric cylinder applies a horizontal thrust to the center point of the push plate through the output end. The force applied through the center ensures that the push plate is subjected to uniform force. This design prevents the push plate from deflecting torque during its movement, ensuring that the positive abutment plate can abut against the long side of the metal casting to form a stable reference positioning surface.

[0011] Specifically, one end of the side abutment plate is fixedly connected to the lower part of one side of the first slider, the first slider is movably sleeved on the outside of the lead screw, and the lead screw is located inside the third slide groove.

[0012] By adopting the above technical solution, the first slider generates a precise linear displacement under the drive of the lead screw. The side abutment plate converts the linear motion of the first slider into a lateral positioning action through a rigid connection. When the side abutment plate contacts the left wide edge of the metal casting, the self-locking characteristic of the lead screw can effectively maintain the positioning pressure and prevent displacement during processing.

[0013] Specifically, the third slide groove is formed inside the push plate, and the third slide groove is connected to the interior of the second slide groove.

[0014] By adopting the above technical solution, the through design of the third slide groove and the second slide groove facilitates the movement of the first slider and the side abutment plate.

[0015] Specifically, a motor is fixedly installed inside the push plate, and the output end of the motor is fixedly connected to one end of the lead screw.

[0016] By adopting the above technical solution, the motor drives the lead screw to rotate at a preset speed. By controlling the number of rotations, the moving distance of the side stop plate can be precisely adjusted to meet the positioning requirements of castings of different sizes.

[0017] Specifically, the mounting box is equipped with a punching mechanism inside, and a die is provided at the bottom of the mounting box, with the die located directly below the punching mechanism.

[0018] By adopting the above technical solution, the punching mechanism can perform punching operations on metal castings by moving downwards.

[0019] The beneficial effects of this utility model are:

[0020] The punching device for metal casting processing described in this utility model can provide a positioning effect for the placement of metal castings through the cooperation of a front abutment plate and a side abutment plate. Castings of the same model only need to be pressed against the front abutment plate and the side abutment plate to achieve punching positioning, which can keep the punching position of metal castings of the same model consistent.

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] As one embodiment of this utility model, such as Figures 1-4 As shown, the punching device for metal casting processing of this utility model includes a mounting box 2 and a push plate 1. The mounting box 2 has an operating cavity 3 inside. The push plate 1 is movably installed inside the operating cavity 3. The bottom of the operating cavity 3 has a first sliding groove 8. There are two first sliding grooves 8. The two first sliding grooves 8 are used for sliding installation of a second slider 15. The second slider 15 is fixedly connected to the bottom end of the push plate 1.

[0029] A positive abutment plate 5 is fixedly connected to the lower part of one side of the push plate 1. A second sliding groove 9 is provided inside the positive abutment plate 5, and the interior of the second sliding groove 9 is used for the sliding installation of the side abutment plate 4.

[0030] In use, the cooperation between the first slide groove 8 and the second slider 15 provides precise guidance for the translation of the push plate 1. When the electric cylinder 14 pushes the push plate 1, the second slider 15 slides synchronously along the double first slide grooves 8 to ensure that the push plate 1 maintains a horizontal movement trajectory in the operating cavity 3, avoiding deviation that causes positioning errors. The positive abutment plate 5 forms a dynamic positioning combination with the side abutment plate 4 through the second slide groove 9 to realize the position calibration in the two-dimensional direction, which facilitates the positioning of the drilling position of the metal casting.

[0031] The present invention also includes an electric cylinder 14 fixedly installed on one side of the mounting box 2, and the output end of the electric cylinder 14 is fixedly connected to the center of one side of the push plate 1.

[0032] In use, the electric cylinder 14 applies a horizontal thrust to the center point of the push plate 1 through its output end. The force applied through the center ensures that the push plate 1 is subjected to uniform force. This design prevents the push plate 1 from deflecting torque during its movement, ensuring that the positive abutment plate 5 can abut against the long side of the metal casting to form a stable reference positioning surface.

[0033] The present invention also includes that one end of the side abutment plate 4 is fixedly connected to the lower part of one side of the first slider 13, the first slider 13 is movably sleeved on the outside of the lead screw 11, and the lead screw 11 is disposed inside the third slide groove 12.

[0034] In use, the first slider 13 generates a precise linear displacement under the drive of the lead screw 11. The side abutment plate 4 converts the linear motion of the first slider 13 into a lateral positioning action through a rigid connection. When the side abutment plate 4 contacts the left wide edge of the metal casting, the self-locking characteristic of the lead screw 11 can effectively maintain the positioning pressure and prevent displacement during processing.

[0035] It should be noted that both ends of the lead screw 11 are fixedly installed inside the push plate 1 via bearing seats.

[0036] The present invention also includes that the third slide groove 12 is formed inside the push plate 1, and the third slide groove 12 is connected to the interior of the second slide groove 9.

[0037] In use, the through design of the third slide groove 12 and the second slide groove 9 facilitates the movement of the first slider 13 and the side abutment plate 4.

[0038] The present invention also includes a motor 10 fixedly installed inside the push plate 1, and the output end of the motor 10 is fixedly connected to one end of the lead screw 11.

[0039] In use, the motor 10 drives the lead screw 11 to rotate at a preset speed. By controlling the number of rotations, the moving distance of the side plate 4 can be precisely adjusted to meet the positioning requirements of castings of different sizes.

[0040] This utility model also includes a punching mechanism 6 inside the mounting box 2, and a concave mold 7 is provided at the bottom of the inner side of the mounting box 2, with the concave mold 7 located directly below the punching mechanism 6.

[0041] When in use, the punching mechanism 6 moves downward to perform punching operations on metal castings. For the specific working principle, please refer to the application number mentioned in the background art.

[0042] In use, the metal casting is first placed in the operating cavity 3, covering the die 7. Then, the electric cylinder 14 and motor 10 are started by an external power source. The electric cylinder 14 pushes the push plate 1 closer to the metal casting until the front abutment 5 abuts against the upper long side of the metal casting. The motor 10 drives the lead screw 11 to rotate, which in turn drives the first slider 13 to move linearly in the third slide groove 12. This causes the side abutment 4 to move linearly in the second slide groove 9 until it abuts against the left wide side of the metal casting. The front abutment 5 and the side abutment 4 then record the punching position of the metal casting of this type. When subsequent metal castings of the same type are placed in the operating cavity 3, the orientation and facing of the metal casting must be the same as the previous one. Simply place the upper long side of the metal casting against the front abutment 5 and the left wide side of the metal casting against the side abutment 4 to perform punching operations at the same position on the same type of metal casting.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
