Description

Technical Field

[0001] The utility model relates to the technical field of mechanical parts processing, in particular to a punching device for mechanical parts processing. Background Art

[0002] Stamping is a commonly used and efficient processing technology in mechanical parts processing. The following is a detailed introduction to it. The basic principle of stamping process: Stamping process is a processing method that uses the strong pressure provided by stamping equipment (usually a stamping machine) and a special stamping die to apply external force to raw materials such as metal or non-metallic sheets, causing them to undergo plastic deformation under the constraint of the die, thereby obtaining mechanical parts with the required shape, size and precision. During the stamping process, the sheet is placed on the lower die of the stamping die, and the slider of the stamping machine drives the punch installed on the upper die to move downward, and cooperates with the lower die to perform operations such as blanking, bending, and stretching on the sheet. After one stamping action is completed, the slider resets and prepares for the next stamping, and this process is repeated to achieve batch processing of parts.

[0003] The existing technical solution has the following defects: after the stamping operation of the mechanical parts is completed, the mechanical parts often appear to be nested on the upper mold. Due to this nesting relationship between the two, the mechanical parts are not easy to fall off, which greatly affects the efficiency of the mechanical parts stamping, making it impossible to reach the ideal state, thereby reducing the overall stamping effect. Utility Model Content

[0004] In order to solve the problems raised in the above-mentioned background technology, the purpose of the present utility model is to provide a stamping device for processing mechanical parts, which has the advantage of easy demoulding and solves the problem that after the stamping operation of the mechanical parts is completed, the mechanical parts are often socketed on the upper mold. Due to this socketing relationship between the two, the mechanical parts are not easy to fall off, which greatly affects the efficiency of the stamping of the mechanical parts and makes it impossible to reach the ideal state, thereby reducing the overall stamping effect.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a stamping device for processing mechanical parts, comprising a base plate, the top of the base plate is fixedly connected to a support frame, the front side of the support frame is fixedly connected to a reinforcing plate, a stamping groove is provided inside the reinforcing plate, a circular hole is provided on the top of the support frame, and a stamping mechanism is provided on the top of the base plate.

[0006] As a preferred embodiment of the present invention, the stamping mechanism includes a hydraulic cylinder, the bottom of the hydraulic cylinder is fixedly connected to the top of the support frame, the output end of the hydraulic cylinder is fixedly connected to a driving plate, the bottom of the driving plate is fixedly connected to a punching head, the interior of the punching head is slidingly connected to an ejection block, and a spring is provided at the bottom of the driving plate, one end of the spring is fixedly connected to the interior of the punching head, and the other end of the spring is fixedly connected to the top of the ejection block.

[0007] As a preferred embodiment of the present invention, a guide frame is fixedly connected to the top of the reinforcing plate, and the guide frame is located on the top of the bottom plate.

[0008] As a preferred embodiment of the present invention, the bottom of the reinforcing plate is fixedly connected to a reinforcing frame, and the rear side of the reinforcing frame is fixedly connected to the surface of the supporting frame.

[0009] As a preferred embodiment of the present invention, a collection frame is fixedly connected to the top of the bottom plate, and the collection frame is located at the bottom of the reinforcing plate.

[0010] As a preferred embodiment of the present invention, the surface of the ejector block is flush with the bottom of the punching head, and the ejector block is located on the top of the reinforcing plate.

[0011] As a preferred embodiment of the present invention, the four corners of the top of the driving plate are fixedly connected with sliding rods, and the outer sides of the sliding rods are slidably connected to the inside of the circular hole.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] 1. The utility model can punch the mechanical parts after the stamping is completed by using the stamping mechanism. At the same time, the use of the ejector block and the spring can prevent the mechanical parts from being sleeved on the surface of the punching head, thereby solving the problem that the mechanical parts are often sleeved on the upper mold after the stamping operation of the mechanical parts is completed. Due to the sleeve connection between the two, the mechanical parts are not easy to fall off, which greatly affects the efficiency of the mechanical parts stamping and makes it impossible to reach the ideal state, thereby reducing the overall stamping effect. The utility model has the advantage of easy demoulding.

[0014] 2. The utility model sets a stamping mechanism. When it is necessary to perform stamping processing on mechanical parts, the raw material to be stamped is first placed in the stamping groove opened by the reinforcing plate to ensure that the raw material is in a suitable processing position. Then the hydraulic cylinder is started, and the output end of the hydraulic cylinder moves downward, thereby driving the driving plate, stamping head, spring, ejector block and sliding rod connected thereto to move downward. In this process, the stamping head gradually approaches the raw material and begins to continuously apply pressure to the raw material, so that the raw material undergoes plastic deformation under the joint action of the stamping head and the stamping groove on the reinforcing plate, completing the stamping action. As the stamping head continues to press downward, when the ejector block contacts the raw material, the ejector block is subjected to the reverse force exerted by the raw material. The ejection block will slide upward along the inside of the punch head, squeezing the spring connected to it at the same time, causing the spring to gradually contract and store elastic potential energy. When the punch head is pressed down to the preset punching stroke, the hydraulic cylinder begins to return under its own control logic, driving the drive plate and the punch head to reset upward together. At the same time, the spring begins to reset with the help of the elastic potential energy stored previously, gradually recovering from the contracted state to the initial state, and in this process generates a downward thrust on the ejection block, pushing the ejection block to move downward. When the ejection block moves downward, it will apply a downward ejecting force to the mechanical parts that have been stamped, so that the mechanical parts remain on the top of the reinforcement plate, avoiding the mechanical parts from being trapped on the surface of the punch head.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figures 1 to 5 As shown, the utility model provides a stamping device for machining mechanical parts, comprising a base plate 1, a support frame 2 fixedly connected to the top of the base plate 1, a reinforcing plate 3 fixedly connected to the front side of the support frame 2, a stamping groove 4 is provided inside the reinforcing plate 3, a circular hole 5 is provided on the top of the support frame 2, and a stamping mechanism 6 is provided on the top of the base plate 1.

[0023] refer to Figure 4 The stamping mechanism 6 includes a hydraulic cylinder 61, the bottom of the hydraulic cylinder 61 is fixedly connected to the top of the support frame 2, the output end of the hydraulic cylinder 61 is fixedly connected to the driving plate 62, the bottom of the driving plate 62 is fixedly connected to the punching head 63, the inside of the punching head 63 is slidably connected to the ejection block 64, and a spring 65 is provided at the bottom of the driving plate 62, one end of the spring 65 is fixedly connected to the inside of the punching head 63, and the other end of the spring 65 is fixedly connected to the top of the ejection block 64.

[0024] As a technical optimization solution of the present invention, by setting a stamping mechanism 6, when it is necessary to perform stamping processing on mechanical parts, the raw material to be stamped is first placed in the stamping groove 4 opened on the reinforcing plate 3 to ensure that the raw material is in a suitable processing position, and then the hydraulic cylinder 61 is started, and the output end of the hydraulic cylinder 61 moves downward, thereby driving the driving plate 62, the stamping head 63, the spring 65, the ejection block 64 and the sliding rod 10 connected thereto to move downward. In this process, the stamping head 63 gradually approaches the raw material and begins to continuously apply pressure to the raw material, so that the raw material undergoes plastic deformation under the joint action of the stamping head 63 and the stamping groove 4 on the reinforcing plate 3, completing the stamping action. As the stamping head 63 continues to press downward, when the ejection block 64 contacts the raw material, due to the reverse force applied by the raw material Under the action of force, the ejector block 64 will slide upward along the inside of the punch head 63, and at the same time squeeze the spring 65 connected to it, causing the spring 65 to gradually shrink and store elastic potential energy. When the punch head 63 is pressed down to the preset punching stroke, the hydraulic cylinder 61 starts the return movement under the action of its own control logic, driving the drive plate 62 and the punch head 63 to reset upward together. At the same time, the spring 65 begins to reset with the help of the elastic potential energy stored previously, gradually recovering from the contracted state to the initial state, and in this process generates a downward thrust on the ejector block 64, pushing the ejector block 64 to move downward. When the ejector block 64 moves downward, it will apply a downward ejecting force to the mechanical parts that have been stamped, so that the mechanical parts remain on the top of the reinforcing plate 3, avoiding the mechanical parts from being sheathed on the surface of the punch head 63.

[0025] refer to Figure 3 The top of the reinforcing plate 3 is fixedly connected with a guide frame 7, and the guide frame 7 is located on the top of the bottom plate 1.

[0026] As a technical optimization solution of the present invention, by setting a guide frame 7, when the operator places the raw material to be stamped, the guide frame 7 can play a precise guiding role, guiding the placement position of the raw material, and effectively avoiding the positional displacement of the raw material during the placement process, thereby ensuring that the raw material can be accurately placed in the preset processing position, laying a good foundation for the subsequent smooth stamping operation.

[0027] refer to Figure 2 The bottom of the reinforcing plate 3 is fixedly connected to a reinforcing frame 8 , and the rear side of the reinforcing frame 8 is fixedly connected to the surface of the supporting frame 2 .

[0028] As a technical optimization solution of the present invention, by setting up a reinforcement frame 8, it can firmly provide strong support for the bottom of the reinforcement plate 3, effectively share the pressure faced by the reinforcement plate 3 when undergoing stamping operations, and thus significantly improve the use strength of the reinforcement plate 3, ensuring that the reinforcement plate 3 can still maintain good structural stability under long-term, high-intensity stamping working environments, and provide reliable guarantees for the smooth progress of stamping operations.

[0029] refer to Figure 2 A collecting frame 9 is fixedly connected to the top of the bottom plate 1 , and the collecting frame 9 is located at the bottom of the reinforcing plate 3 .

[0030] As a technical optimization solution of the present invention, by setting up a collection frame 9, it can efficiently collect the metal debris generated after the stamping is completed, avoiding the metal debris from scattering everywhere and affecting the working environment. At the same time, it is also convenient for the subsequent centralized processing of these debris, ensuring the cleanliness and orderliness of the stamping work area, and improving the standardization and safety of the overall operation.

[0031] refer to Figure 4 The surface of the ejector block 64 is flush with the bottom of the punch head 63 , and the ejector block 64 is located on the top of the reinforcing plate 3 .

[0032] As a technical optimization solution of the present invention, the surface of the ejector block 64 is flush with the bottom of the punch head 63. During the stamping process, the ejector block 64 can cooperate with the punch head 63 to ensure that the mechanical parts are subjected to uniform and stable force during stamping, and effectively avoid defects such as uneven surface and broken edges of the mechanical parts after stamping due to local uneven force, thereby ensuring the stamping quality of the mechanical parts and enabling them to better meet subsequent use and assembly requirements.

[0033] refer to Figure 2 The four corners of the top of the driving plate 62 are fixedly connected with sliding rods 10, and the outer side of the sliding rod 10 is slidably connected with the inner side of the circular hole 5.

[0034] As a technical optimization solution of the present invention, by setting a sliding rod 10, when the driving plate 62 moves downward in the vertical direction under the drive of the hydraulic cylinder 61, the sliding rod 10 can slide accurately and smoothly along the circular hole 5 corresponding to the top of the support frame 2, so that it is firmly confined in a predetermined direction during the movement, thereby effectively maintaining stability, avoiding shaking, offset, etc., and thus ensuring that the stamping action can be carried out accurately and smoothly, laying a solid foundation for high-quality stamping processing of mechanical parts.

[0035] The working principle and use process of the present invention are as follows: when it is necessary to perform stamping processing on mechanical parts, first place the raw material to be stamped in the stamping groove 4 opened on the reinforcing plate 3 to ensure that the raw material is in a suitable processing position, then start the hydraulic cylinder 61, and the output end of the hydraulic cylinder 61 moves downward, thereby driving the driving plate 62, the punching head 63, the spring 65, the ejector block 64 and the sliding rod 10 connected thereto to move downward. In this process, the punching head 63 gradually approaches the raw material and begins to continuously apply pressure to the raw material, so that the raw material undergoes plastic deformation under the joint action of the punching head 63 and the stamping groove 4 on the reinforcing plate 3, completing the stamping action. As the punching head 63 continues to press downward, when the ejector block 64 contacts the raw material, it is ejected due to the reverse force applied by the raw material. The block 64 will slide upward along the inside of the punch head 63, squeezing the spring 65 connected to it, causing the spring 65 to gradually contract and store elastic potential energy. When the punch head 63 is pressed down to the preset punching stroke, the hydraulic cylinder 61 starts the return movement under the action of its own control logic, driving the drive plate 62 and the punch head 63 to reset upward together. At the same time, the spring 65 begins to reset with the help of the elastic potential energy stored previously, gradually returning to the initial state from the contracted state, and in this process generates a downward thrust on the ejection block 64, pushing the ejection block 64 to move downward. When the ejection block 64 moves downward, it will apply a downward ejecting force to the mechanical parts that have been stamped, so that the mechanical parts remain on the top of the reinforcing plate 3, avoiding the mechanical parts from being covered on the surface of the punch head 63.

[0036] To sum up: the stamping device for processing mechanical parts, through the coordinated use of the base plate 1, the support frame 2, the reinforcing plate 3, the stamping groove 4, the circular hole 5 and the stamping mechanism 6, solves the problem that after the stamping operation of the mechanical parts is completed, the mechanical parts often appear to be socketed on the upper mold. Due to this socketing relationship between the two, the mechanical parts are not easy to fall off, which greatly affects the efficiency of the stamping of the mechanical parts and makes it impossible to reach the ideal state, thereby reducing the overall stamping effect.
