Abstract
Description
Technical Field
[0001] This application relates to the field of molds, and particularly to a round tube punching and cutting mold. Background Art
[0002] The round tube cutting mold is one of the common devices in industrial production, and its main function is to cut the round tube into a predetermined length. However, the existing round tube cutting molds usually have a relatively simple structure, mainly including a fixed seat or a fixed sleeve, and a cutting punch adapted thereto. This fixed structure can work effectively under specific conditions, but faces many challenges in the production process.
[0003] Firstly, the adaptability of the existing round tube cutting molds is poor. When production requires cutting round tubes of different sizes, the existing molds cannot be adjusted flexibly, and corresponding fixed seats or fixed sleeves must be replaced, or even the cutting punch needs to be replaced. This not only increases the downtime during the production process, but also greatly reduces the production efficiency. The process of replacing the mold is time-consuming and laborious, and requires the operator to make multiple adjustments and tests to ensure the cutting accuracy and quality. This method obviously does not meet the high requirements of modern industrial production for flexibility and rapid response.
[0004] Secondly, the existing fixed round tube cutting molds are prone to wear during the processing, resulting in a shortened service life of the mold. Since each replacement of the mold components requires shutdown operation, it not only affects the production progress, but also increases the production cost. In addition, the frequent replacement and adjustment process may lead to a decrease in the fitting accuracy of the mold components, thus affecting the cutting quality and increasing the rejection rate.
[0005] In addition, the current punching and cutting mold does not have the function of detecting the cut surface and the function of detecting the incoming round tube, which is not conducive to product quality supervision and automatic production control.
[0006] In summary, the existing round tube cutting molds have problems such as poor adaptability, complex operation, low efficiency, and easy wear. These problems not only limit the flexibility and rapid response ability of the production line, but also increase the production cost and affect the market competitiveness of the enterprise. Therefore, it is urgent to develop a new type of round tube cutting mold to solve the deficiencies in the existing technology and improve the production efficiency and cutting quality. Utility Model Content

[0008] To achieve the above object, the present application discloses a circular tube punching die, which includes a lower die base, a tube clamping assembly arranged on the lower die base, an upper die base relatively cooperating with the lower die base, and a punching and detecting assembly installed on the upper die base and opposite to the tube clamping assembly. Among them, the upper die base and the lower die base are in guiding cooperation through a guide pillar and guide sleeve structure; a lower backing plate is provided on the upper surface of the lower die base, the tube clamping assembly is installed on the lower backing plate, and a latch for driving the tube clamping assembly to clamp is installed on the upper die base and opposite to the tube clamping assembly; the tube clamping assembly includes a fixed block fixed on the lower backing plate, a slider slidably installed on the lower backing plate opposite to the fixed block, and a spring connected and cooperating with the slider for resetting the slider; semi-circular notches are formed on the opposite sides of the fixed block and the slider, and when the fixed block and the slider cooperate, the two semi-circular notches cooperate to clamp the circular tube; a slope is provided on the slider and relatively cooperates with the latch, and when the latch descends, it contacts the slope and pushes the slider close to the fixed block; the punching and detecting assembly includes a punch holder installed on the lower surface of the upper die base, a cutting punch installed on the punch holder, a photoelectric sensor installed on the punch holder, and a camera and a lighting source simultaneously installed on the punch holder.
[0009] In some embodiments, a stop block relatively cooperating with the slider is installed on the lower backing plate, and the slider has an initial position through the cooperation of the stop block and the spring.
[0010] In some embodiments, mounting grooves are concavely provided in the semi-circular notches of the fixed block and the slider, and elastic rubber blocks are installed in the mounting grooves, and the elastic rubber blocks protrude 1-2 mm above the groove surface.
[0011] In some embodiments, a rubber cushion block with a thickness of 0.5-1 mm for buffering is clamped between the punch holder and the upper die base.
[0012] Compared with the prior art, the present application has at least the following beneficial effects:
[0013] 1. The tube clamping assembly realizes the reset function of the slider through the spring. The cooperation of the semi-circular notches of the fixed block and the slider can effectively clamp the circular tube, improving the adaptability and reliability of clamping.
[0014] 2. The elastic rubber blocks installed in the notches achieve buffering during the clamping process, avoiding surface abrasion caused by the position deviation of the circular tube, and ensuring the stability and accuracy of the circular tube during the cutting process.

[0025] As Figure 1 、 2 shown, this embodiment discloses an exemplary structure of a circular tube punching die. Specifically, this die includes a lower die base 1, a tube clamping assembly 2, an upper die base 3, and a punching detection assembly 4.
[0026] The die realizes guiding and mating through the guide pillar and guide sleeve structure between the upper die base 1 and the lower die base 3, thereby ensuring the stability and accuracy of the upper die base 3 and the lower die base 1 during operation.
[0027] As a common sense, it can be understood that the separation and combination of the upper die base 3 and the lower die base 1 are realized by an external punching press or similar device / mechanism, which provides vertical pressure and movement to complete the cutting operation.
[0028] It should be understood that, in order to ensure the operation stability and accuracy of the die, the guide pillars and guide sleeves are made of high-strength steel and the surfaces are chrome-plated to improve wear resistance and corrosion resistance. During the installation and use of the die, the guide pillar and guide sleeve structure can provide accurate guiding, ensuring the synchronous movement of the upper die base and the lower die base during punching, and avoiding cutting errors caused by die offset.
[0029] In the specific structure, a lower backing plate 101 is provided on the upper surface of the lower die base 1, and the tube clamping assembly 2 is installed on the lower backing plate 101. A plug pin 301 is installed on the upper die base 3 for driving the tube clamping assembly 2 to clamp the circular tube.
[0030] Furthermore, the tube clamping assembly 2 includes a fixed block 201, a slider 202, and a spring 203. The fixed block 201 is fixed on the lower backing plate 101, the slider 202 is slidably installed on the lower backing plate 101 and is connected to the spring 203 to achieve reset. The spring 203 is made of high-elasticity steel and cooperates with a stop block 208 provided on the lower backing plate 101 to ensure that the slider 202 can quickly reset during the clamping and releasing processes. The fixed block 201 and the slider 202 in the tube clamping assembly 2 are made of high-quality alloy steel materials to ensure their strength and durability.
[0031] Specifically, the fixed block 201 is fixed on the lower backing plate 101 by bolts. A guide block protrudes from the lower surface of the slider 202, and this guide block can freely slide in the guide groove on the lower backing plate 101, thereby realizing the sliding fit between the slider 202 and the lower backing plate 101.
[0032] Further, the fixing block 201 and the sliding block 202 are provided with semi-circular notch-like openings 204 on their opposite sides. When the fixing block 201 and the sliding block 202 are engaged, the two semi-circular notch-like openings 204 can clamp the round tube. The sliding block 202 is provided with an inclined surface 205 that cooperates with the pin 301. When the pin 301 moves downward, it contacts the inclined surface 205 and pushes the sliding block 202 closer to the fixing block 201.
[0033] It should be understood that the inner wall of the semi-circular notch-like opening 204 is precisely machined and has a smooth surface, which can reduce the friction and damage to the surface of the round tube.
[0034] When the round tube needs to be cut, first place the round tube in the semi-circular notch-like opening 204 between the fixing block 201 and the sliding block 202. The pin 301 on the upper die base 3 moves downward, and the bottom of the pin contacts the inclined surface 205 on the sliding block 202, pushing the sliding block 202 towards the fixing block 201, thereby clamping the round tube. To further protect the surface of the round tube, an installation groove 206 is provided in the semi-circular notch-like opening 204, and an elastic rubber block 207 is installed in the installation groove 206. The elastic rubber block 207 is made of a high-elastic rubber material and protrudes 1-2 mm above the groove surface, which can provide buffering during the clamping process and avoid surface abrasion caused by the position deviation of the round tube.
[0035] In this embodiment, the punching and cutting detection assembly 4 includes a punch holder 401, a cutting punch 402, a photoelectric sensor 403, a camera 404, and a lighting source 405 installed on the lower surface of the upper die base 3.
[0036] The punching and cutting detection assembly 4 plays a key role during the cutting process.
[0037] Further, the photoelectric sensor 403 is installed at an appropriate position on the punch holder 401 to monitor the position and state of the round tube in real time. The photoelectric sensor 401 uses a high-precision sensor, which can accurately capture the position change of the round tube to ensure the accuracy of the cutting position.
[0038] Furthermore, the camera 404 and the lighting source 405 work together to provide a clear visual detection means. The camera 404 captures images during the cutting process, and the lighting source 405 ensures sufficient light in the cutting area, enabling the camera 404 to obtain clear photos.
[0039] It should be understood that the external data processing device, software programs, and algorithms relied on for visual detection are all well-known prior arts and not the protection objects of this application, so no detailed description will be given. Those skilled in the art can fully understand and implement these technologies and utilize existing programs or publicly known open-source programs to achieve them.
[0040] During the punching process, the cutting punch 402 moves downward under the guidance of the punch holder 401 to cut the round tube. To reduce the impact force, a rubber cushion block with a thickness of 0.5 - 1 mm for buffering is clamped between the punch holder 401 and the upper die base 3. The rubber cushion block is made of high-strength wear-resistant rubber material, which can effectively absorb the impact force, protect the die structure, and extend the service life of the die.
[0041] After cutting is completed, the cutting punch 402 returns to its initial position, and the spring 203 pushes the slider 202 to reset, releasing the round tube. The entire operation process is efficient and stable, adapting to the cutting requirements of round tubes of different sizes, and has high flexibility and adaptability.
[0042] Compared with traditional round tube cutting devices, the design of the tube clamping assembly 2 in this die can effectively improve the clamping stability of the round tube, and provide buffering through the elastic rubber block 207, avoiding damage to the surface of the round tube caused by uneven clamping force in traditional devices; the intelligent design of the punching and detection assembly 4 realizes real-time monitoring and adjustment of the cutting process, ensuring cutting accuracy and quality. In addition, the buffer rubber cushion block between the punch holder 401 and the upper die base 3 effectively reduces the impact force during the punching process, protects the die structure, and extends the service life of the die.
[0043] Through the above various designs and improvements, this round tube punching die realizes efficient, precise and stable round tube cutting operations, overcomes multiple deficiencies in traditional technologies, improves production efficiency and product quality, and has broad application prospects and market value.
[0044] 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 within 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.
