Description

Technical Field

[0001] This utility model relates to the technical field of fabric needle production, and in particular to a clamping device for blanking nonwoven needles. Background Technology

[0002] Heading and blanking is a key process in needle manufacturing, mainly referring to the shaping and processing of the head of the needle semi-finished product (usually a metal rod). Through processes such as stamping and grinding, the head of the needle semi-finished product is machined into a rounded structure. Before heading and blanking, the needle semi-finished product is first clamped and fixed using a clamping mechanism to ensure its stability during the heading and blanking process and prevent processing errors caused by shaking. In the prior art, the utility model patent with patent application number 202222994090.3 discloses a clamping device for non-woven fabric needle heading blank preparation, which mainly consists of an upper clamping block and a lower clamping block. When heading the needle semi-finished product, the upper clamping block and the lower clamping block clamp and fix the needle semi-finished product, and then the heading machine can be used to head the needle semi-finished product. However, the following problems exist in the use of this device: when heading the needle semi-finished product, because the head of the needle semi-finished product has high hardness and low plasticity, the needle semi-finished product is prone to breakage when shaping the head of the needle semi-finished product, which is inconvenient to use. Therefore, a clamping device that can improve the plasticity of the head of the needle semi-finished product is needed. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a clamping device for nonwoven fabric needle heading blank preparation that can heat the head of the needle semi-finished product before heading, improve the plasticity of the needle semi-finished product head, reduce the risk of breakage during heading, and is convenient to use, reliable and practical.

[0004] This utility model discloses a clamping device for nonwoven fabric needle heading blank preparation, comprising a base plate and a disc; it also includes a clamping mechanism, a rotating mechanism, and a heating mechanism. The disc is mounted on the rotating mechanism, which rotates the disc. The clamping mechanism is mounted on the disc and has a clamping and fixing function. The heating mechanism is mounted on the base plate and is located above the clamping mechanism. The working part of the heading machine is located above the disc. During the needle production process, when it is necessary to head the semi-finished needle, the semi-finished needle is first clamped and fixed by the clamping mechanism, and then the head of the semi-finished needle is headed by the heating mechanism. The device heats the head of the semi-finished needle, increasing its plasticity. Then, a rotating mechanism is activated, causing the disc to rotate the clamping mechanism below the heading machine. This rotates the heated semi-finished needle below the heading machine, where the heading machine heads the needle. The headed needle is then removed from the clamping mechanism. This method heats the head of the semi-finished needle before heading, increasing its plasticity and reducing the risk of breakage during heading. It is convenient to use and highly reliable and practical.

[0005] Preferably, the clamping mechanism includes a support block, a fixed block, a hydraulic cylinder, a push rod, and a clamping plate. The support block is fixedly installed on the upper end of the disc, and a groove is provided inside the support block. The fixed block is fixedly installed in the groove of the support block. The hydraulic cylinder is fixedly installed on the left end of the support block. The push rod is slidably installed on the support block, and the left end of the push rod is connected to the output end of the hydraulic cylinder. The clamping plate is fixedly installed on the right end of the push rod and slidably installed on the support block. When clamping and fixing the needle semi-finished product, the needle semi-finished product is placed in the groove of the support block, so that the needle semi-finished product is located between the fixed block and the clamping plate. Then, the hydraulic cylinder is opened, and the hydraulic cylinder moves the clamping plate to the right through the push rod, thereby pressing the needle semi-finished product onto the fixed block. The lower part of the needle semi-finished product is clamped and fixed by the fixed block and the clamping plate, improving the stability of the needle semi-finished product.

[0006] Preferably, the rotating mechanism includes an electric turntable, a support shaft, and a fixed frame. The electric turntable is fixedly installed on the upper end of the base plate, the support shaft is installed on the rotating end of the electric turntable, and a disc is fixedly installed on the upper end of the support shaft. The disc and the support shaft are coaxial. The fixed frame is fixedly installed on the base plate, and the support shaft is rotatably installed on the fixed frame. After the needle semi-finished product is heated on the clamping mechanism, the electric turntable is turned on. The electric turntable drives the support shaft to rotate, which in turn causes the disc to drive the clamping mechanism and the needle semi-finished product to rotate, so that the heated needle semi-finished product can be rotated to the bottom of the heading machine for heading. This facilitates the movement of the needle semi-finished product.

[0007] Preferably, the heating mechanism includes a support frame, an electric slide rail, a lifting block, and an electromagnetic heater. The support frame is fixedly installed on the base plate, the electric slide rail is fixedly installed on the upper end of the support frame, the lifting block is installed on the electric slide rail, and the electric slide rail is used to move the lifting block up and down. The electromagnetic heater is fixedly installed on the lifting block, and an electromagnetic heating coil is provided on the electromagnetic heater, which is located above the clamping mechanism. When heating the needle semi-finished product, the needle semi-finished product is first clamped and fixed by the clamping mechanism. Then, the needle semi-finished product is rotated to the underside of the electromagnetic heating coil. Then, the electric slide rail is opened, and the electric slide rail drives the lifting block and the electromagnetic heater to descend, thereby causing the electromagnetic heating coil to descend so that the head of the needle semi-finished product is located in the electromagnetic heating coil. Then, the electromagnetic heater is opened, and the electromagnetic heating coil heats the head of the needle semi-finished product through electromagnetic induction, improving the plasticity of the head of the needle semi-finished product and reducing the risk of breakage during heading. Then, the electromagnetic heating coil is raised, and the needle semi-finished product is moved to the underside of the heading machine for heading. Heating the head of the needle semi-finished product facilitates heading.

[0008] Preferably, it also includes a fixing plate, a fan, and a blower pipe. The fixing plate is fixedly installed on the upper part of the base plate, and the fan is fixedly installed on the upper part of the fixing plate. The output end of the fan is provided with a blower pipe, with the output end of the blower pipe facing downwards and the blower pipe located above the disc. After the needle semi-finished product is headed below the heading machine, the disc is rotated by the rotating mechanism, which in turn rotates the clamping mechanism and the headed needle semi-finished product to the lower part of the blower pipe. Then, the fan is turned on, and cold air is blown onto the needle semi-finished product through the blower pipe to dissipate heat and cool the needle semi-finished product, which facilitates the disassembly of the needle semi-finished product.

[0009] Preferably, both the fixing block and the clamping plate are provided with a high-temperature resistant coating; the high-temperature resistance of the fixing block and the clamping plate is improved by the above-mentioned arrangement.

[0010] Preferably, the hydraulic cylinder is equipped with a dust cover.

[0011] Compared with the prior art, the advantages of this utility model are: the head of the needle semi-finished product can be heated before the needle semi-finished product is headed, which improves the plasticity of the head of the needle semi-finished product, reduces the risk of breakage when the needle semi-finished product is headed, and is convenient to use, reliable and practical.

[0019] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example 1

[0020] like Figures 1 to 6 The present invention relates to a clamping device for nonwoven fabric needle heading and blanking, comprising a base plate 1, a disc 2, a clamping mechanism, a rotating mechanism, and a heating mechanism. The disc 2 is mounted on the rotating mechanism, which rotates the disc 2. The clamping mechanism is mounted on the disc 2 and has a clamping and fixing function. The heating mechanism is mounted on the base plate 1 and is located above the clamping mechanism. The working part of the heading machine 19 is located above the disc 2. During the needle production process, when it is necessary to head the needle semi-finished product 20, the needle semi-finished product 20 is first clamped and fixed by the clamping mechanism, and then the head of the needle semi-finished product 20 is heated by the heating mechanism to make the needle head... The head of the semi-finished product 20 is heated to improve its plasticity. Then, the rotating mechanism is opened, causing the disc 2 to drive the clamping mechanism to rotate below the heading machine 19. This causes the heated semi-finished product 20 to rotate below the heading machine 19. The heading machine 19 then heads the semi-finished product 20. After that, the headed semi-finished product 20 can be removed from the clamping mechanism. The head of the semi-finished product 20 can be heated before heading, which improves its plasticity and reduces the risk of breakage during heading. It is convenient to use and has high reliability and practicality.

[0021] like Figure 1 , Figure 5 and Figure 6 The clamping mechanism includes a support block 3, a fixing block 4, a hydraulic cylinder 5, a push rod 6, and a clamping plate 7. The support block 3 is fixedly installed on the upper end of the disc 2. A sliding groove is provided inside the support block 3. The fixing block 4 is fixedly installed in the sliding groove of the support block 3. The hydraulic cylinder 5 is fixedly installed on the left end of the support block 3. The push rod 6 is slidably installed on the support block 3. The left end of the push rod 6 is connected to the output end of the hydraulic cylinder 5. The clamping plate 7 is fixedly installed on the right end of the push rod 6. The clamping plate 7 is slidably installed on the support block 3.

[0022] When clamping and fixing the needle semi-finished product 20, the needle semi-finished product 20 is placed in the slide groove of the support block 3, so that the needle semi-finished product 20 is located between the fixing block 4 and the clamping plate 7. Then, the hydraulic cylinder 5 is opened, and the hydraulic cylinder 5 moves the clamping plate 7 to the right through the push rod 6, thereby pressing the needle semi-finished product 20 onto the fixing block 4. The lower part of the needle semi-finished product 20 is clamped and fixed by the fixing block 4 and the clamping plate 7, thereby improving the stability of the needle semi-finished product 20.

[0023] like Figure 1 and Figure 4 The rotating mechanism includes an electric turntable 8, a support shaft 9, and a fixed frame 10. The electric turntable 8 is fixedly installed on the upper end of the base plate 1. The support shaft 9 is installed on the rotating end of the electric turntable 8. The disc 2 is fixedly installed on the upper end of the support shaft 9 and is coaxial with the support shaft 9. The fixed frame 10 is fixedly installed on the base plate 1, and the support shaft 9 is rotatably installed on the fixed frame 10. After the needle semi-finished product 20 is heated on the clamping mechanism, the electric turntable 8 is opened. The electric turntable 8 drives the support shaft 9 to rotate, which in turn causes the disc 2 to drive the clamping mechanism and the needle semi-finished product 20 to rotate, so that the heated needle semi-finished product 20 can be rotated to the bottom of the heading machine 19 for heading. This facilitates the movement of the needle semi-finished product 20.

[0024] like Figure 1 , Figure 2 and Figure 3The heating mechanism includes a support frame 11, an electric slide rail 12, a lifting block 13, and an electromagnetic heater 14. The support frame 11 is fixedly installed on the base plate 1. The electric slide rail 12 is fixedly installed on the upper end of the support frame 11. The lifting block 13 is installed on the electric slide rail 12, which is used to move the lifting block 13 up and down. The electromagnetic heater 14 is fixedly installed on the lifting block 13. An electromagnetic heating coil 15 is provided on the electromagnetic heater 14, and the electromagnetic heating coil 15 is located above the clamping mechanism. When heating the needle semi-finished product 20, the needle semi-finished product 20 is first clamped and fixed by the clamping mechanism, and then the needle semi-finished product 20 is rotated to a position below the electromagnetic heating coil 15. Then, the electric slide rail 12 is opened, which drives the lifting block 13 and the electromagnetic heater 14 to descend, thereby causing the electromagnetic heating coil 15 to descend, so that the head of the needle semi-finished product 20 is located in the electromagnetic heating coil 15. Then, the electromagnetic heater 14 is opened, so that the electromagnetic heating coil 15 heats the head of the needle semi-finished product 20 through electromagnetic induction, which improves the plasticity of the head of the needle semi-finished product 20 and reduces the risk of breakage of the needle semi-finished product 20 during heading. Then, the electromagnetic heating coil 15 is raised, and the needle semi-finished product 20 is moved to the bottom of the heading machine 19 for heading. By heating the head of the needle semi-finished product 20, the heading of the needle semi-finished product 20 is facilitated.

[0025] Both the fixing block 4 and the clamping plate 7 are coated with a high-temperature resistant coating; this coating improves the high-temperature resistance of the fixing block 4 and the clamping plate 7. The hydraulic cylinder 5 is equipped with a dust cover. Example 2

[0026] like Figure 1 and Figure 2 Based on Embodiment 1, it also includes a fixing plate 16, a fan 17, and a blower pipe 18. The fixing plate 16 is fixedly installed on the upper end of the base plate 1, and the fan 17 is fixedly installed on the upper end of the fixing plate 16. The output end of the fan 17 is provided with a blower pipe 18, with the output end of the blower pipe 18 pointing downwards and the blower pipe 18 located above the disc 2. After the needle semi-finished product 20 is headed under the heading machine 19, the disc 2 is rotated by the rotating mechanism, thereby rotating the clamping mechanism and the headed needle semi-finished product 20 to below the blower pipe 18. Then, the fan 17 is turned on, and cold air is blown onto the needle semi-finished product 20 through the blower pipe 18 to dissipate heat and cool the needle semi-finished product 20, which facilitates the disassembly of the needle semi-finished product 20.
