Description

Technical Field

[0001] This utility model relates to the field of cooler housing production technology, and in particular to a punching device for producing engine cooler housings. Background Technology

[0002] The engine radiator, also known as the engine water tank, is a key component of the cooling system of a water-cooled engine. The engine water tank consists of a shell, a water inlet, and cooling pipes. Punching is a common process step in manufacturing these components. During the machining of the water tank shell, holes need to be punched, such as connection holes for assembling and securing components.

[0003] When punching existing water tank shell workpieces, the workpiece is first clamped and fixed by a clamping and positioning mechanism, and then the punch is moved by a power mechanism to punch the workpiece. After punching is completed, the punch moves up and away from the workpiece.

[0004] However, there may be risks when punching thin-walled water tank shells. When the punch completes the punching and moves upward away from the workpiece, there will be frictional resistance between the workpiece and the punch. This will cause the part of the workpiece near the punch to tend to be lifted upward, while the part of the workpiece away from the punch is clamped and fixed by the clamping and positioning mechanism, which will make the workpiece prone to tensile deformation and damage. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where thin-walled water tank shells are easily lifted upwards and deformed due to the frictional resistance of the punch. Therefore, this invention proposes a punching device for the production of engine cooler shells.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: Design a punching device for producing engine cooler housings, including a base, a support column fixedly mounted on the upper surface of the base, a top plate fixedly mounted on the upper end of the support column, a first telescopic member fixedly mounted inside the top plate, a lifting frame fixedly mounted on the lower end of the first telescopic member, a guide rod slidably mounted inside the lifting frame, a pressure plate fixedly mounted on the lower end of the guide rod, a sleeve block fixedly mounted on the upper surface of the pressure plate, a spring fixedly connected to the inner side of the sleeve block, the upper end of the spring fixedly connected to the lifting frame, a punch fixedly mounted on the lower surface of the lifting frame, and a bearing mechanism fixedly mounted on the top of the base.

[0007] Preferably, the supporting mechanism includes a platform, which is fixedly installed on the upper surface of the base. The platform has a through hole inside, and a pair of second telescopic members are fixedly installed in the bottom of the base. A sliding frame is fixedly installed at the end of the second telescopic member.

[0008] Preferably, a miniature push rod is fixedly installed inside the platform, and an ejector frame is fixedly installed at the end of the miniature push rod, with the through hole penetrating the ejector frame.

[0009] Preferably, the second telescopic component is an electric telescopic rod.

[0010] Preferably, a flexible sleeve is bonded to the outer side of the upper end of the sliding frame, and the interior of the flexible sleeve is made of rubber.

[0011] Preferably, the pressure plate has two positional states: first, both the pressure plate and the sleeve block are far away from the lifting frame, the spring is in an extended state, and the lower end of the punch is located above the pressure plate; second, the pressure plate is close to the lifting frame, the upper end of the sleeve block is in contact with the lower surface of the lifting frame, the spring is in a compressed state, and the lower end of the punch extends to below the pressure plate.

[0012] Preferably, a buffer pad is fixedly installed on the lower surface of the pressure plate, and the buffer pad is made of rubber.

[0013] Preferably, the first telescopic component is an electric telescopic rod.

[0014] The present invention discloses a punching device for producing engine cooler housings, which has the following advantages: When the punching device is in operation, by setting springs and structures, it can ensure that after punching is completed, the pressure plate moves behind the punch 10. During the process of the punch moving up and separating from the workpiece, the pressure plate always abuts against the workpiece surface, which can prevent the workpiece from being lifted up and damaged due to the friction between it and the punch, and can play a protective role for thin-walled workpieces.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Example 1: Refer to Figure 1-4 A punching device for producing engine cooler housings includes a base 1, a support column 2 fixedly mounted on the upper surface of the base 1, a top plate 3 fixedly mounted on the upper end of the support column 2, a first telescopic member 4 fixedly mounted inside the top plate 3, the first telescopic member 4 being an electric telescopic rod, and a lifting frame 5 fixedly mounted on the lower end of the first telescopic member 4, which can drive the lifting frame 5 to move up and down. A guide rod 6 is slidably mounted inside the lifting frame 5, a pressure plate 7 is fixedly mounted on the lower end of the guide rod 6, a sleeve block 8 is fixedly mounted on the upper surface of the pressure plate 7, and a spring 9 is fixedly connected to the inner side of the sleeve block 8. The upper end of the spring 9 is fixedly connected to the lifting frame 5, and under the elastic force of the spring 9, the pressure plate 7 always has an elastic tendency to move away from the lifting frame 5.

[0019] A punch 10 is fixedly installed on the lower surface of the lifting frame 5. The punch 10 moves with the activation of the first telescopic member 4, and can punch holes in the workpiece. A buffer pad 18 is fixedly installed on the lower surface of the pressure plate 7. The buffer pad 18 is made of rubber. When the pressure plate 7 presses the workpiece, the buffer pad 18 can flexibly adapt to the uneven structure of the workpiece surface and prevent damage to the workpiece surface from hard contact.

[0020] The pressure plate 7 has two position states. First, both the pressure plate 7 and the sleeve block 8 are far away from the lifting frame 5, the spring 9 is in an extended state, and the lower end of the punch 10 is above the pressure plate 7. At this time, the punch 10 is hidden inside the sleeve block 8, which can protect the punch 10 and prevent it from being damaged by collision when it is not working. Second, the pressure plate 7 is close to the lifting frame 5, the upper end of the sleeve block 8 is in contact with the lower surface of the lifting frame 5, the spring 9 is in a compressed state, and the lower end of the punch 10 extends to the bottom of the pressure plate 7. At this time, the punch 10 punches downwards, and the pressure plate 7 presses against the upper surface of the workpiece. When the punch 10 moves upwards away from the workpiece for a short time, the pressure plate 7 will still press against the upper surface of the workpiece under the elastic force of the spring 9, which can press the workpiece as a whole and can prevent the punch 10 from being damaged by upward frictional resistance when it leaves the workpiece.

[0021] A support mechanism is fixedly installed on the top of the base 1. The support mechanism is used to support, position, and clamp the workpiece, maintaining its stable position. The function of the support mechanism can be achieved by existing structures; therefore, the specific structure of the support mechanism will not be described in detail here.

[0022] Working principle: When the punching device for producing engine cooler housings is in operation, the workpiece is placed on the base 1 and positioned by the bearing mechanism. The first telescopic component 4 is activated, causing the lifting frame 5 to move downwards. The downward movement of the lifting frame 5 causes the punch 10 and pressure plate 7 to move downwards synchronously. Once the lower surface of the pressure plate 7 contacts and abuts against the upper surface of the workpiece, the lifting frame 5 continues to move downwards. The pressure plate 7 and guide rod 6 can no longer move downwards, but the punch 10 continues to move downwards, compressing the spring 9 until the punch 10 contacts the workpiece and performs the punching process. The waste material punched out by the punch 10 is discharged into the base 1 through the through hole 14 for unified collection. The process involves the first telescopic component 4 driving the lifting frame 5 upward. During the short period of time that the punch 10 moves upward, the pressure plate 7 remains stationary and always presses against the workpiece. The spring 9 will gradually extend until the upper end of the guide rod 6 is in contact with the upper surface of the lifting frame 5. Only then will the pressure plate 7 move upward along with the lifting frame 5. The reason for making the pressure plate 7 move after the punch 10 moves upward is to ensure that the pressure plate 7 always presses against the surface of the workpiece during the process of the punch 10 moving upward and separating from the workpiece. This prevents the workpiece from being lifted upward and damaged due to the friction between it and the punch 10, thus protecting the thin-walled workpiece.

[0023] Example 2: Refer to Figure 1-2 In another preferred embodiment of this utility model, based on embodiment 1, the supporting mechanism includes a platform 11, which is fixedly installed on the upper surface of the base 1. A through hole 14 is provided inside the platform 11. A pair of second telescopic members 15 are fixedly installed inside the bottom of the base 1. The second telescopic members 15 are electric telescopic rods. A sliding frame 16 is fixedly installed at the end of the second telescopic members 15. When the second telescopic members 15 are activated, they can drive the sliding frame 16 to move left and right, and can clamp the workpiece through the sliding frame 16. Furthermore, a displacement sensor device is installed on the second telescopic members 15 to control the telescopic distance, so that the second telescopic members 15 at both ends can clamp the workpiece more accurately.

[0024] A flexible sleeve 17 is bonded to the outer side of the upper end of the sliding frame 16. The flexible sleeve 17 is made of rubber and can provide flexible protection, adapt to the irregular surface of the workpiece, and also play a role in preventing slippage.

[0025] A miniature push rod 13 is fixedly installed inside the platform 11. An ejector frame 12 is fixedly installed at the end of the miniature push rod 13. A through hole 14 is provided through the ejector frame 12. After the workpiece is punched and the punch 10 and the pressure plate 7 are both moved to a safe distance, the second telescopic component 15 is activated to drive the ejector frame 12 to move upward. The upward movement of the ejector frame 12 can adjust the height of the workpiece. The height of the ejector frame 12 can be adjusted according to the specific thickness of the workpiece so that the upper surface of the ejector frame 12 is flush with the upper surface of the platform 11.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
