Description

Technical Field

[0001] This utility model relates to the technical field of cable sleeve processing equipment, and in particular to a CPVC cable sleeve punching and blanking device. Background Technology

[0002] Cable protection conduits play a crucial role in power systems and communication networks, protecting cables from physical damage and environmental factors. CPVC (chlorinated polyvinyl chloride) pipes are widely used in cable protection due to their corrosion resistance and high-temperature resistance. However, perforations need to be machined at predetermined locations on the wall of the CPVC cable conduit to facilitate connection and installation with other components during on-site construction. During the punching process, the CPVC cable conduit is placed on the punching machine, punched, and then removed from the machine. This process lacks automatic unloading after punching, making the punching operation cumbersome, discontinuous, time-consuming, and labor-intensive. Furthermore, the CPVC cable conduit needs to be positioned and fixed on the punching machine to prevent displacement during punching. Therefore, a CPVC cable conduit punching and unloading device is designed to achieve automatic positioning, fixing, and unloading of the CPVC cable conduit, thus meeting the requirements of CPVC cable conduit punching operations. Utility Model Content

[0003] To address the aforementioned technical problems, the purpose of this utility model is to propose a CPVC cable sleeve punching and feeding device that can automatically position and fix CPVC cable sleeves and automatically feed them. The punching operation is simple and continuous, saving time and effort, effectively meeting the punching operation requirements of CPVC cable sleeves, and is highly practical.

[0004] The technical solution of this utility model is achieved as follows: a CPVC cable sleeve punching and blanking device, including a table, a support block, a drive mechanism, and a pushing component;

[0005] The platform is provided with a material discharge port; the material discharge port is provided with material guide grooves at intervals; the upper end of the material guide groove is exposed above the platform; the width of the material guide groove is adapted to the outer diameter of the cable sleeve.

[0006] The two sets of support blocks are arranged at a distance from each other between the two material guide grooves, forming a support space between them that corresponds to the upper and lower parts of the material discharge port.

[0007] The drive assembly is used to drive the two side blocks to move closer or further apart in the left-right direction;

[0008] The pushing assembly is located at one end of the support block and includes a slider that slides back and forth, a push plate on the slider, and a spring between the slider and the platform. The push plate is located above the feeding guide groove and has an abutment surface facing the support block. The abutment surface is provided with an insertion boss. The insertion boss has an outer peripheral surface for close contact with the inner peripheral surface of the cable sleeve. The support block is provided with a wedge-shaped surface facing the slider. The slider is provided with a wedge-shaped mating surface that mates with the wedge-shaped surface.

[0009] Furthermore, the material feeding guide groove includes a vertical extension section and a horizontal extension section formed by bending and extending from the lower end of the vertical extension section; the vertical extension section is disposed inside the material feeding port.

[0010] Furthermore, the punching and feeding device includes a punching assembly; the punching assembly is disposed on one or both sides of the support block in the left-right direction, and has a punching end that faces the support space and moves left and right; an avoidance channel is provided on the moving path of the support block corresponding to the punching end.

[0011] Furthermore, an arc-shaped notch is provided on one side of the top surface of the support block; when the two support blocks on both sides come close to each other and close together, the two arc-shaped notches combine to form an arc-shaped groove; the supporting space is formed inside the arc-shaped groove.

[0012] Furthermore, the bottom of the supporting space is lower than the top of the unloading guide groove.

[0013] Furthermore, the outer circumferential surface of the insertion boss is an arc surface larger than half the circumference.

[0014] Furthermore, the outer circumferential surface of the insertion boss is provided with concave and convex structures spaced apart along the circumferential direction.

[0015] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0016] 1. This utility model utilizes the cooperative use of the pushing components. When the two side supports approach each other, driven by the spring, the push plate abuts against one end of the CPVC cable sleeve in the support space, pushing the CPVC cable sleeve to move within the support space and abut against the feeding guide groove on the other side, thus limiting the axial movement of the CPVC cable sleeve. Simultaneously, the insertion boss can be inserted into one end of the CPVC cable sleeve to further position it and restrict its rotation. Furthermore, the CPVC cable sleeve enters the feeding guide groove, which limits its radial movement. When the two side supports move away from each other, the wedge-shaped surface and wedge-shaped mating surface cause the push plate and insertion boss to disengage from the CPVC cable sleeve, allowing the CPVC cable sleeve to fall between the two supports and be discharged through the feeding port. The combination of the above methods enables automatic positioning and fixing of CPVC cable sleeves and automatic feeding. The punching operation is simple and continuous, saving time and labor, effectively meeting the punching operation requirements of CPVC cable sleeves, and is highly practical.

[0017] 2. With the cooperation of the feeding guide groove, when the CPVC cable sleeve is fed, it can move in the feeding guide groove on both sides to achieve orderly feeding, which facilitates the subsequent movement and handling of the CPVC cable sleeve and other operations. It is highly practical. Attached Figure Description

[0028] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0029] like Figures 1-8 The image shows a CPVC cable conduit punching and blanking device according to this embodiment, applied to punching holes in the wall of a fixed-length CPVC cable conduit. The punching and blanking device includes a platform 1, a support block 3, a drive mechanism, and a pushing assembly. The platform 1 has a discharge port 11. This discharge port 11 is adapted to the length and outer diameter of the CPVC cable conduit, allowing the CPVC cable conduit to fall laterally through the discharge port 11. Discharge guide grooves 2 are installed at intervals between the front and rear ends of the discharge port 11. The cross-section of the discharge guide grooves 2 is a "U" shape, with both ends and the opposing surfaces of the two grooves open. The width of the discharge guide grooves 2 is adapted to the outer diameter of the cable conduit, allowing the CPVC cable conduit to be inserted into the discharge guide grooves 2 and radially limited. The distance between the bottom surfaces of the two feeding guide grooves 2 is slightly greater than the length of the CPVC cable sleeve, allowing the CPVC cable sleeve to be placed horizontally between the two feeding guide grooves 2, with both ends of the CPVC cable sleeve able to enter the corresponding feeding guide groove 2. The upper ends of both feeding guide grooves 2 are exposed above the platform 1. In the specific structural design, the upper end of the first feeding guide groove 2 is higher than the upper end of the second feeding guide groove 2. When the CPVC cable sleeve has a preset height relative to the platform 1, the first end of the CPVC cable sleeve is completely inserted into the first feeding guide groove 2, while the second end of the CPVC cable sleeve partially enters the second feeding guide groove 2, partially exposed above the second feeding guide groove 2.

[0030] The aforementioned unloading guide trough 2 has a designed length, including a vertical extension section 21 and a horizontal extension section 22 formed by bending and extending from the lower end of the vertical extension section 21. The vertical extension section 21 is arranged inside the unloading port 11. The CPVC cable sleeve can slide from the vertical extension section 21 to the horizontal extension section 22 and move out from one end of the horizontal extension section 22.

[0031] In this embodiment, the aforementioned two sets of support blocks 3 are arranged at intervals between the two feeding guide grooves 2. The two sets of support blocks 3 have a length extending in the front-back direction and are slidably mounted on the platform 1 via sliding grooves. A supporting space 31 corresponding to the material discharge port 11 is formed between the two sets of support blocks 3. When the two sets of support blocks 3 are driven away from each other, the bottom of the supporting space 31 is opened to communicate with the material discharge port 11. When the two sets of support blocks 3 are driven closer together, the CPVC cable sleeve can be arranged horizontally in the supporting space 31. Specifically, an arc-shaped notch 311 is processed on the top surface of the support block 3 on the side closest to each other, and the arc-shaped notch 311 extends in the front-back direction. When the two support blocks 3 on both sides approach and close together, the two arc-shaped notches 311 combine to form an arc-shaped groove; the arc-shaped groove is adapted to the outer diameter of the CPVC cable sleeve, and the supporting space 31 is formed inside the arc-shaped groove.

[0032] In the specific structural design, the bottom of the support space 31 is lower than the top of the unloading guide groove 2, so that when the CPVC cable sleeve is placed in the support space 31, the CPVC cable sleeve can enter the unloading guide grooves 2 on both sides.

[0033] The aforementioned drive assembly 4 is fixed on the platform 1 and is used to drive the two side blocks 3 to move closer or further apart in the left-right direction. The drive assembly 4 is preferably a prior art device such as an oil pipe, cylinder, or electric push rod.

[0034] It should be noted that, driven by the drive component 4, the two support blocks 3 have a first position where they are close to each other, a feeding position where they are far apart from each other, and a dropping position where they are far apart from each other. In the feeding position, the distance between the two support blocks 3 is less than the width of the dropping opening 11, preventing the CPVC cable sleeve from falling when placed into the supporting space 31. In the dropping position, the distance between the two support blocks 3 is greater than the width of the dropping opening 11, allowing the CPVC cable sleeve in the supporting space 31 to fall from between the two support blocks 3 into the dropping opening 11.

[0035] The pushing assembly is installed at one end of the support block 3, located on one side of the lower-height unloading guide groove 2. This pushing assembly includes a slider 6, a push plate 61, and springs 7. The slider 6 is slidably mounted on the pedal via a sliding rod. The push plate 61 is fixed to the slider 6. Several springs 7 are installed between the platform 1 and the slider 6, providing elasticity to keep the slider 6 moving towards the support block 3. The push plate 61 is located above the unloading guide groove 2. When the push plate 61 moves towards the support block 3, it can pass over the unloading guide groove 2 and abut against the end of the CPVC cable sleeve on the support space 31. The push plate 61 has an abutment surface facing the support block 3. An insertion boss is installed on this abutment surface. When the abutment surface abuts against the end of the CPVC cable sleeve, the insertion boss 62 simultaneously inserts into the interior of the CPVC cable sleeve. The outer diameter of the insertion boss 62 is adapted to the inner diameter of the CPVC cable sleeve, giving the insertion boss 62 an outer circumferential surface for close contact with the inner circumferential surface of the cable sleeve. To avoid the material guide groove 2, the insertion boss 62 is not a complete cylindrical structure; its outer circumferential surface is an arc surface larger than half a circumference. The outer circumferential surface of the insertion boss 62 is machined with intermittent concave-convex structures 621 along the circumferential direction to increase friction when in contact with the CPVC cable sleeve. Through this structural design, when the insertion boss 62 is inserted into one end of the CPVC cable sleeve, it can restrict the radial movement of the CPVC cable sleeve and limit its rotation.

[0036] The slider 6 has wedge-shaped surfaces 33 on both support blocks 3 facing the slider 6. Both sides of the slider 6 are machined with wedge-shaped mating surfaces 63 that mate with the wedge-shaped surfaces 33. These wedge-shaped surfaces 33 and 63 slide together, so that when the two support blocks 3 move away from each other, the slider 6 moves away from the support blocks 3. When the two support blocks 3 move closer together, the slider 6 moves closer to the support blocks 3 under the action of the spring 7.

[0037] In this embodiment, a punching assembly 5 is arranged on one or both sides of the support block 3 in the left-right direction. The punching assembly 5 has a punching end 51 facing the support space 31 and movable left-right. An avoidance channel 32 is provided on the support block 3 along the movement path corresponding to the punching end 51. Through the movement of the punching end 51, the wall of the CPVC cable conduit placed on the support space 31 can be punched from the side. The punching assembly 5 includes a punch and a driver for driving the punch to move left and right. The driver is preferably a conventional device such as a cylinder or hydraulic cylinder.

[0038] In practical use, the drive assembly 4 drives the two side support blocks 3 to move apart by a certain distance, placing the CPVC cable sleeve into the support space 31 between the two side support blocks 3. Both ends of the CPVC cable sleeve enter the two side feeding guide grooves 2, thus radially limiting the CPVC cable sleeve. The drive assembly 4 drives the two side support blocks 3 to move closer together, initially limiting the CPVC cable sleeve within the support space 31. When the two side support blocks 3 move closer together, the push plate 61 moves under the drive of the spring 7, abutting against one end of the CPVC cable sleeve in the support space 31, pushing the CPVC cable sleeve to move within the support space 31 and abut against the feeding guide groove 2 on the other side, thus axially limiting the CPVC cable sleeve. Simultaneously, the insertion boss 62 is inserted into one end of the CPVC cable sleeve to further position the CPVC cable sleeve and restrict its rotation. The punching assembly 5 punches holes in the wall of the CPVC cable sleeve from the side. After processing, the two support blocks 3 are driven to move away from each other to a certain distance. Under the action of the wedge-shaped surface 33 and the wedge-shaped mating surface 63, the push plate 61 and the insertion boss 62 disengage from the CPVC cable sleeve. Blocked by the material guide groove 2 on one side, the CPVC cable sleeve will not move out of the support space 31. The CPVC cable sleeve can fall between the two support blocks 3 and be discharged through the discharge port 11. Then, guided by the material guide grooves 2 on both sides, the CPVC cable sleeve moves in the material guide grooves 2 on both sides and is output. Through the above method, the automatic positioning and fixing and automatic feeding of the CPVC cable sleeve can be realized. The punching operation is simple and continuous, saving time and labor. It realizes the orderly feeding of the CPVC cable sleeve, effectively meets the punching operation requirements of the CPVC cable sleeve, and has strong practicality.
