Description

Technical Field

[0001] The present invention relates to a wire duct processing device, specifically to a side stamping die for low-smoke and halogen-free wire ducts. Background Art

[0002] The materials used in low-smoke and halogen-free wire ducts do not release toxic substances during production, use, and combustion, and have characteristics such as low smoke, halogen-free, fireproof, and temperature-resistant. Therefore, they are widely used in places with high material requirements, such as subways, nuclear power plants, semiconductor manufacturing, shipbuilding, oil platforms, etc. However, when processing punching holes with traditional wire duct processing equipment, problems such as deformation and burrs are likely to occur. For example, in the utility model patent "A wire duct through-hole punching tooling and a wire duct through-hole punching system (patent number: 202420159902.9)", its stamping side hole die is to make a corresponding groove die according to the shape and size of the wire duct, and then punch through holes through the side of the punch. However, due to a certain gap in the female die, problems such as deformation and burrs are likely to occur, which is not conducive to use. Moreover, the dies of this kind of equipment need to be customized for each product, that is, corresponding dies need to be customized for each specification of the product, resulting in high production costs. Summary of the Invention

[0003] The purpose of the present invention is to solve the above technical problems existing in the processing of low-smoke and halogen-free wire ducts by existing wire duct processing equipment, and to provide a side stamping die for low-smoke and halogen-free wire ducts with excellent performance.

[0004] The side stamping die for low-smoke and halogen-free wire ducts includes a hydraulic cylinder, a die base, a punch, and a die. An elastic side pressing mechanism is arranged between the punch and the die, and a downward pressing mechanism is arranged above the die. The elastic side pressing mechanism is elastically telescopically installed on one side of the punch. When the hydraulic cylinder pushes the punch to cooperate with the die for stamping and processing the product, the elastic side pressing mechanism first compresses the processed product, and the downward pressing mechanism compresses the processed product and fixes it on the die.

[0005] Further, the die base includes a base plate, a first fixing plate, a movable plate, and a second fixing plate. The first fixing plate, the movable plate, and the second fixing plate are sequentially installed on the base plate. The hydraulic cylinder is fixedly installed on the first fixing plate, the punch is installed on the movable plate, the die is fixedly installed at the front side of the lower position of the second fixing plate, and an avoidance hole is provided on the second fixing plate. The hydraulic cylinder pushes the movable plate to drive the punch and the elastic side pressing mechanism to pass through the avoidance hole and cooperate with the die for processing the product.

[0006] Further, the punch includes a bottom plate and one or more punching needles on the bottom plate. The punching needles are fixed on the movable plate through the bottom plate; the die is a fixed block provided with a punching hole, and the punching hole corresponds to the shape, size, and quantity of the punching needles.

[0007] Furthermore, two or more upper guide pillars are provided at the high position of the bottom plate of the punch, and two or more lower guide pillars are provided at the low position of the bottom plate. The elastic side pressing mechanism is slidably installed on the upper and lower guide pillars of the bottom plate and is in corresponding limit fit with the punch. When the die is fixedly installed on the base, it is positioned on the lower guide pillars of the bottom plate to form an accurate fitting and fixing position with the punch.

[0008] Furthermore, the elastic side pressing mechanism is a movable pressing plate installed on the bottom plate. The movable pressing plate is smaller than the clearance hole. A through hole through which the punching needle on the punch passes is provided on the movable pressing plate, and a compression spring is provided between the movable pressing plate and the bottom plate of the punch.

[0009] Furthermore, the shape, size and number of the through hole correspond to those of the punching needle on the punch.

[0010] Furthermore, the lower blank pressing mechanism is composed of an adjusting plate and two or more pressing wheels of the adjusting plate. The lower blank pressing mechanism is installed on the second fixing plate through the adjusting plate.

[0011] Furthermore, the adjusting plate is formed by bending and pressing the two sides of a flat plate in the reverse 90° direction, so that the adjusting plate forms an adjusting and fixing part, a connecting part and a lower pressing part. The adjusting plate is installed on the second fixing plate in an up-and-down adjustable manner through the adjusting and fixing part, and the pressing wheel is installed at the lower pressing part position to form a downward pressing state.

[0012] Furthermore, two parallel horizontal sliding tracks are provided above the base, and two parallel longitudinal sliding grooves are provided below the base. The first fixing plate, the movable plate, the second fixing plate and the lower part of the die are respectively provided with horizontal interfaces corresponding to the horizontal sliding tracks, and the bracket is provided with a longitudinal guide rail corresponding to the longitudinal sliding grooves.

[0013] Furthermore, a detachable lifting and guiding convex block is provided at the upper part of the die.

[0014] Advantages of the present invention:

[0015] 1. An elastic side pressing mechanism is provided between the punch and the die of the present invention, and a lower blank pressing mechanism is provided above the die. Therefore, when processing a product (low-smoke and halogen-free wire trough), the low-smoke and halogen-free wire trough is pressed tightly on the die through the elastic side pressing mechanism and the lower blank pressing mechanism, and then punching is performed through the punch. Therefore, problems such as easy deformation and multiple burrs during punching of the low-smoke and halogen-free wire trough are effectively avoided.

[0016] 2. The present invention is provided with a detachable and replaceable lifting and guiding convex block at the upper part of the female die. When stamping through holes, the force-bearing area between the low-smoke and halogen-free wire groove and the female die is increased through the lifting and guiding convex block, or the contact area pressed by the downward blanking mechanism is increased at the same time, thereby better avoiding large jitter of the product during processing, further improving the processing quality of the product, better avoiding problems such as deformation and multiple burrs, and at the same time, the corresponding lifting and guiding convex block can be replaced according to different low-smoke and halogen-free wire grooves.

[0017] 3. The elastic side pressing mechanism and the female die of the present invention are fixed through the cooperation of the upper guide post and the lower guide post, which better realizes the precise cooperation with the male die and improves the processing quality of the product.

[0018] 4. The female die of the present invention is a fixed block, and the downward blanking mechanism can be adjusted up and down to compress the position, so it can be used to process low-smoke and halogen-free wire grooves of various models without affecting the processing quality, such as processing low-smoke and halogen-free wire grooves with different groove widths.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Referring to Figures 1 to 6 The side stamping die for the low-smoke and halogen-free wire groove shown, the side stamping die 3 includes a hydraulic cylinder 31, a die base 32, a male die 33 and a female die 34. An elastic side pressing mechanism 35 is provided between the male die 33 and the female die 34, and a downward blanking mechanism 5 is provided above the female die 34; the elastic side pressing mechanism 35 is elastically and telescopically installed on one side of the male die 33, and when the hydraulic cylinder 31 pushes the male die 33 to cooperate with the female die 34 to stamp and process the product, the elastic side pressing mechanism 35 first compresses the processed product, and at the same time, the downward blanking mechanism 5 compresses the processed product and fixes it on the female die 34.

[0027] In the embodiment, the die holder 32 includes a base 321, a first fixing plate 322, a movable plate 323 and a second fixing plate 324. The first fixing plate 322, the movable plate 323 and the second fixing plate 324 are sequentially installed on the base 321 and are positioned and connected to each other by a plurality of guide posts 325. The hydraulic cylinder 31 is fixedly installed on the first fixing plate 322, and the telescopic rod of the hydraulic cylinder 31 passes through the through hole provided in the first fixing plate 322 and is connected to the movable plate 323. The punch 33 is installed on the movable plate 323, and the die 34 is fixedly installed at the front side of the lower position of the second fixing plate 324. The second fixing plate 324 is provided with a clearance hole 3241, and the clearance hole is a square hole. The hydraulic cylinder 31 pushes the movable plate 323 to drive the punch 33 and the elastic side pressing mechanism 35 to pass through the clearance hole 3241 and cooperate with the die 34 to process (punch through holes) the product.

[0028] The punch 33 includes a bottom plate 331 and one or more punching needles 332 on the bottom plate 331. The punching needles 332 are fixed on the movable plate 323 through the bottom plate 331. The die 34 is a fixed block provided with a punching hole 341, and the punching hole 341 corresponds to the shape, size and number of the punching needles 332. Two or more upper guide posts 333 are provided at the high position of the bottom plate 331 of the punch 33, and two or more lower guide posts 334 are provided at the low position of the bottom plate 331.

[0029] The elastic side pressing mechanism 35 is slidably installed on the upper guide posts 333 and the lower guide posts 334 of the bottom plate 331 and is in corresponding limit cooperation with the punch 33. As shown in the figure, the elastic side pressing mechanism 35 is cooperatively installed on the upper guide posts 333 and the lower guide posts 334, so that the elastic side pressing mechanism 35 can move back and forth on the upper guide posts 333 and the lower guide posts 334. When the die 34 is fixedly installed on the base 321, a certain distance is reserved from one side of the second fixing plate 324, and it is in cooperation with the lower guide posts 334 of the bottom plate 331 to be positioned at the corresponding position of the punching stroke of the punch 33. As shown in the figure, the bottom of the die 34 is fixed to the base 321, and the die 34 is provided with through holes for cooperative installation with the lower guide posts 334, so that the relative movement between the punch 33, the elastic side pressing mechanism 35 and the die 34 is restricted in the same straight line position, better ensuring the processing accuracy of the product. That is, the punch 334, the elastic side pressing mechanism 35 and the die 3 are cooperatively connected through a plurality of lower guide posts 334 to be restricted in the same straight line during the working movement, and the elastic side pressing mechanism 35 is also cooperatively connected with the upper guide posts 333 at the same time, so that the elastic side pressing mechanism 35 is evenly stressed when pushed by the hydraulic cylinder 31 and moves more smoothly. The length of the upper guide posts 333 is less than that of the lower guide posts 334, so that after the punch 33, the elastic side pressing mechanism 35 and the die 34 are installed, a low-smoke and halogen-free wire groove feeding channel is reserved between the punch 33 and the die 34.

[0030] The elastic side pressing mechanism 35 is a movable pressing plate installed on the bottom plate 331. The movable pressing plate is square and smaller than the clearance hole 3241. A through hole 3111 through which the punching needle 332 on the punch 33 passes is provided on the movable pressing plate. The thickness of the movable pressing plate is smaller than the length of the punching needle 332 on the punch 33, so that the punching needle 332 can pass through the movable pressing plate into the die 34. A compression spring 3112 is provided between the movable pressing plate and the bottom plate 331 of the punch 33, enabling the movable pressing plate to elastically expand and contract on the bottom plate 331 of the punch 33. A plurality of positioning blind holes 335 are provided on the bottom plate 331, and the compression spring 3112 is installed between the bottom plate 331 and the movable pressing plate (elastic side pressing mechanism 35) through the positioning blind holes 335. When in use, the elastic side pressing mechanism 35 passes through the clearance hole 3241 under the push of the hydraulic cylinder 31, and presses the processed product against the die 34 through the compression spring 3112. Then, the hydraulic cylinder 31 continues to push the punch 33 to the die 34 to process the product, preventing the processed product from shifting during stamping on the die 34 and improving the quality of the stamped product.

[0031] The shape, size and quantity of the through hole 3111 on the elastic side pressing mechanism 35 correspond to those of the punching needle 332 on the punch 33.

[0032] The lower material pressing mechanism 5 is composed of an adjusting plate 51 and two or more pressing wheels 52 of the adjusting plate 51. The lower material pressing mechanism 5 is installed on the second fixing plate 324 through the adjusting plate 51. Specifically, the adjusting plate 51 is formed by bending and pressing the two sides of a flat plate in opposite directions by 90°. As shown in the figure, one side part (upper part) of the adjusting plate 51 is bent upward by 90°, and the other part (lower part) is bent downward by 90°, so that the adjusting plate 51 forms an adjusting and fixing part 511, a connecting part 512 and a lower pressing part 513. An adjusting notch 514 is provided on the adjusting and fixing part 511 of the adjusting plate 51. The adjusting plate 51 is installed on the second fixing plate 324 through the adjusting notch 514 of the adjusting and fixing part 511 by screws, forming an up-and-down adjustable structure. The pressing wheel 52 is installed at the lower pressing part 513 to form a downward pressing state, and the pressing wheel is a rubber wheel.

[0033] To facilitate the adjustment of the working position of the side stamping die 3, two parallel horizontal sliding tracks 3211 are provided above the base 321, and two parallel longitudinal sliding grooves 3212 are provided below the base 321. A scale 12 is provided on the installation platform 11 of the frame 1 at the corresponding positions of the horizontal sliding tracks 3211 and the longitudinal sliding grooves 3212. The first fixing plate 322, the second fixing plate 324 and the lower part of the female die 34 are respectively provided with horizontal interfaces 6 corresponding to and cooperating with the horizontal sliding tracks 3211. A longitudinal guide rail 7 corresponding to and cooperating with the longitudinal sliding grooves 3212 is provided on the installation platform 11 of the bracket 1. Thus, the first fixing plate 322, the second fixing plate 324 and the female die 34 can be adjustably (movable) installed on the horizontal sliding tracks 3211 on the base 321 through the horizontal interfaces 6 to form the function of adjusting the horizontal position, and the horizontal position to be moved can be adjusted through the scale 12. At the same time, it can be adjustably installed on the longitudinal guide rail 7 on the bracket 1 through the longitudinal sliding grooves 3212 of the base 321 to form the function of adjusting the longitudinal position, and the longitudinal position to be moved can be adjusted through the scale 12.

[0034] A slide-out material guide groove 342 is provided outside the stamping hole 341, and this slide-out material guide groove 342 is used to smoothly discharge the waste materials punched out.

[0035] A detachable lifting guide protrusion 343 is provided on the upper part of the female die 34. When punching through holes, by means of the lifting guide protrusion, the stress area between the low-smoke and halogen-free wire groove and the female die is increased, or the contact area of the downward pressing mechanism pressing down is increased at the same time, thereby better avoiding large jitters of the product during processing and improving the processing quality of the product. The lifting guide protrusion 343 can be replaced with a corresponding lifting guide protrusion according to different low-smoke and halogen-free wire grooves.

[0036] When in use, the present invention is installed on a frame 1. A conveying device 2, a side stamping die 3 and a bottom stamping die 4 are provided on the frame 1. The conveying device 2 is used to convey the processed products, the side stamping die 3 is used to laterally stamp the processed products, and the bottom stamping die 4 is used to vertically stamp the processed products.

[0037] In the embodiment, the frame 1 includes an installation platform 11 for installing a conveying device 2, a side stamping die 3, and a bottom stamping die 4. The conveying device 2 includes a front traction conveying mechanism 21 and a rear traction conveying mechanism 22. The front traction conveying mechanism 21 and the rear traction conveying mechanism 22 are located at both ends of the installation platform 11 of the frame 1. A conveying path for processing products is formed between the front traction conveying mechanism 21 and the rear traction conveying mechanism 22. The side stamping die 3 can be one or more than two. Specifically, when there are more than two side stamping dies 3, the side stamping dies 3 are staggeredly distributed on one side or both sides of the conveying path between the front traction conveying mechanism 21 and the rear traction conveying mechanism 22, and are used for punching through holes on one side or both sides of the product (low-smoke and halogen-free wire trough), that is, the side stamping die 3 distributed on one side of the conveying path punches the through holes on the corresponding side of the processed product.
