Description

Technical Field

[0001] This application relates to the field of punching processing, and in particular to a pipe fitting punching device. Background Art

[0002] In the prior art, the punching technology for pipe fittings has been widely applied in various pipe fitting processing, especially the simultaneous punching of multi-hole pipe fittings. However, in practical applications, this technology has exposed some deficiencies, affecting the processing efficiency and product quality. Although the existing pipe fitting punching devices can complete the basic punching tasks, when dealing with the simultaneous punching of multiple holes, the problem of waste material jamming often occurs.

[0003] The occurrence of this jamming phenomenon is mainly due to the fact that a large amount of waste material generated during the punching process is difficult to be discharged smoothly. When the waste material accumulates in the punching area, especially in the case of simultaneous punching of multiple holes, the waste material is more likely to jam in the punching device, resulting in the blockage of the punching part. This blockage will not only affect the subsequent punching operation, making the equipment unable to work properly, but also cause damage to the pipe fittings themselves, such as surface scratches or hole deformation. The emergence of these problems has greatly reduced the production efficiency and increased the production cost.

[0004] In addition, due to the failure to handle the waste material jamming in a timely manner, the device will generate additional friction and pressure during continuous operation, which may lead to the wear and damage of the equipment, and even pose a safety hazard. The punching devices in the prior art usually lack an effective waste material handling mechanism and cannot quickly remove the jammed waste material, thus further exacerbating the above problems. These deficiencies in the prior art have significantly limited the reliability and efficiency of the multi-hole pipe fitting punching process.

[0005] In view of this, it is of great significance and value to develop a punching device that can effectively solve the problem of waste material jamming. Summary of the Utility Model

[0006] The purpose of this application is to at least overcome one deficiency existing in the prior art, and provide a pipe fitting punching device. This device uses a core-pulling device to achieve punching processing and take out the waste material for treatment, and at the same time conducts detection to ensure the safe and stable operation of the punching work.

[0007] To achieve the above object, the present application discloses a pipe fitting punching device, which includes a base, a movable seat disposed opposite to the base, a core-pulling component and a material discharging component installed on the base, and a punching component installed on the movable seat. Among them, a fixture with a semi-circular working slot is installed on the base, and the fixture is used to install the pipe fittings to be punched; the punching component is relatively matched with the fixture; at least one core-pulling component is installed beside the fixture, and the core-pulling component has at least one core-pulling rod that can be horizontally inserted / extracted into / from the pipe fitting on the fixture along the axial direction of the pipe fitting, and several waste through slots are vertically provided on the core-pulling rod; the punching component includes a floating pressure plate opposite to the fixture and at least one punch for punching through the floating pressure plate. When the punch works, it is opposite to the waste through slot and moves downward to punch the pipe fitting, and the waste after punching is located in the waste through slot; the material discharging component is opposite to the core-pulling component, and the material discharging component includes at least one waste push rod that is pushed by a cylinder to expand and contract relative to the core-pulling rod, and the core-pulling rod pushes the waste in the waste through slot out.

[0008] Further, the material discharging component further includes at least one photoelectric sensor for detecting whether there is waste in the waste through slot.

[0009] Further, the base and the movable seat are connected by a guide rod and a return spring for a resetable guiding fit; the movable seat is driven by an external mechanism to approach the base.

[0010] Further, the core-pulling component is installed beside the fixture through a bracket and avoids the punching component.

[0011] Further, the material discharging component is installed directly above the core-pulling component through a bracket and avoids the punching component.

[0012] Further, the lower section of the waste through slot is a flared slot.

[0013] Compared with the prior art, the waste through slot on the core-pulling rod of the present application can smoothly take the waste out of the pipe fitting, reducing the risk of waste jamming, and then discharging it by the waste push rod. The material discharging component pushes the waste push rod through the cylinder to achieve the rapid discharge of the waste. At the same time, the photoelectric sensor monitors the waste condition in real time and starts the discharging process in time, further improving the working efficiency and intelligent level of the equipment.

[0021] As Figure 1 shown, this embodiment discloses a pipe fitting punching device, which includes a base 1, a movable seat 3 arranged opposite to the base 1, a core-pulling assembly 5 and a discharging assembly 7 installed on the base 1, and a punching assembly installed on the movable seat 3. A jig 2 with a semi-circular working slot is installed on the base 1, and the jig 2 is used to stably install the pipe fitting to be punched. The movable seat 3 is driven by an external punching press and can move horizontally along the guiding device, approaching or departing from the base 1.

[0022] The punching assembly includes a floating pressure plate opposite to the jig 2 and at least one punch 4. The punch 4 descends through the floating pressure plate during work to punch the pipe fitting. The punching assembly cooperates with the jig 2 relatively to ensure accuracy and stability during the punching process.

[0023] The core pulling assembly 5 is installed next to the jig 2, and includes at least one core pulling rod 6 that can be horizontally inserted into or pulled out of the pipe on the jig 2 along the axial direction of the pipe. A number of waste grooves are vertically arranged on the core pulling rod 6 to accommodate waste during the punching process, and the lower section of the waste groove is a flared groove, so that waste is not easily stuck in the waste groove. When the core pulling rod 6 is inserted into the pipe, it acts as a fixed seat for punching to prevent the pipe from deforming during punching, and makes the waste groove cooperate with the punch 4, which is equivalent to the working seat of the punch 4. After the punching is completed, the waste remains in the waste groove, and when the core pulling rod 6 is pulled out, the waste is taken out of the pipe together.

[0024] The discharge assembly 7 is located on the side opposite to the core pulling assembly 5, and includes at least one discharge push rod 8 that is pushed and retracted by a cylinder. The discharge push rod 8 is aligned with the waste channel of the core pulling rod 6, and the waste is pushed out of the waste channel through the push rod action to ensure that the waste will not accumulate in the device and avoid jamming. The discharge assembly 7 does not work every time, and will only work when it detects that the waste channel is non-conductive (that is, when the waste is stuck in the waste channel). In addition, the discharge assembly 7 also includes at least one photoelectric sensor for real-time detection of the waste status in the waste channel to ensure that the waste can be cleaned in time.

[0025] The base 1 and the movable seat 3 are connected by a guide rod and a reset spring. The cooperation of the guide rod and the reset spring enables the movable seat 3 to approach the base 1 under the drive of the external punching machine and automatically reset after the punching is completed. The core pulling component 5 is installed next to the jig 2 through a bracket, and avoids the punching component, so that the core pulling and punching operations do not interfere with each other. The discharge component 7 is also installed directly above the core pulling component 5 through a bracket, and avoids the punching component to ensure the coordinated work between the components.

[0026] The working process is as follows:

[0027] The pipe to be processed is placed in the semicircular working groove of the fixture 2 to ensure that the pipe is stably placed. The design of the fixture 2 can adapt to pipes of different diameters and lengths, which increases the applicability of the device.

[0028] The external punch drives the movable seat 3 to move horizontally, so that the punching assembly is close to the fixture 2. The floating clamp applies appropriate pressure to the pipe during the punching process to fix the position of the pipe and prevent it from moving.

[0029] The core pulling assembly 5 is started, and the core pulling rod 6 is horizontally inserted into the pipe fitting to act as a fixed seat for punching to prevent the pipe fitting from deforming during punching. At this time, the waste slot and the punch 4 are matched, which is equivalent to the working female seat of the punch 4.

[0030] The punch 4 passes through the floating pressure plate to punch the pipe. The waste generated during the punching process enters the waste groove of the core pulling rod 6 through the action of the punch 4. The lower section of the waste groove is a flared groove, so that the waste is not easy to get stuck.

[0031] After the punching is completed, the core-pulling rod 6 is withdrawn from the pipe fitting, and at the same time, the waste material is taken out together. At this time, the photoelectric sensor of the material discharging assembly 7 detects the condition of the waste material to determine whether the waste material needs to be cleaned up.

[0032] The material discharging push rod 8 extends under the push of the cylinder, aligns with the waste material through groove of the core-pulling rod 6, and pushes the waste material out of the through groove. The design of the material discharging push rod 8 ensures the smooth discharge of the waste material and avoids the waste material getting stuck in the device. The material discharging assembly 7 will only be activated when it detects that the through groove for waste material is not conducting, further improving the working efficiency and reliability of the device.

[0033] With this design, the device solves the problem of waste material getting stuck in the traditional punching device. In the traditional punching device during the simultaneous punching of multiple holes, the waste material is prone to accumulate, causing instability in the punching process and affecting the production efficiency. However, through the cooperation of the waste material through groove of the core-pulling rod 6 and the material discharging push rod 8, this device can efficiently clean up the waste material and ensure the continuity and stability of the punching process.

[0034] It should be understood that the main components such as the base 1, the movable seat 3, and the punch 4 are made of high-strength steel and wear-resistant materials, ensuring the durability and stability of the equipment. The design of the guide rod and the return spring ensures that the movable seat 3 can quickly return to its original position, improving the operation convenience and production efficiency. The cooperation between the floating pressure plate and the punch 4 realizes high-precision punching operation. The design of the waste material through groove and the material discharging push rod 8 effectively solves the problem of waste material getting stuck and ensures the continuous and stable operation of the device.

[0035] This device is applicable to the punching processing of various pipe fittings, especially suitable for the simultaneous punching of multiple holes. Through this device, the efficiency and quality of the punching processing can be significantly improved, the risk of waste material getting stuck can be reduced, and the overall working efficiency and stability of the production line can be enhanced. In actual use, this device can adapt to the processing requirements of pipe fittings of different specifications and materials, and is widely used in the pipe fitting manufacturing and processing industries, with significant economic benefits and market value.

[0036] Although the exemplary embodiments of the present disclosure have been described, those skilled in the art should understand that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure in essence. Therefore, all changes and modifications are included in the protection scope of the present disclosure defined by the claims. The present disclosure is defined by the appended claims, and equivalents of these claims are also included.
