Description

Technical Field

[0001] The present application relates to the field of tube processing, and in particular to a punching device and a manufacturing process for a football goal tube. Background Art

[0002] The goal is mainly composed of metal rods welded together. It has a high structural strength and can withstand high-speed impact of the ball. However, due to its large size and fixed shape, it is difficult to store and move. It is usually placed at a fixed position on the sports field for athletes to practice or compete. It is difficult for athletes to set up the goal for practice outside the sports field.

[0003] In order to solve this problem, the goal in the related art can be assembled into a goal by using joints. The disassembled pipes and joints can not only greatly reduce the storage space, but also be more convenient for transportation, so that athletes can set up the goal by themselves outside the stadium for practice.

[0004] During the production process of pipes, it is usually necessary to grind the outer diameter of one end of the pipe so that the outer diameter of the spigot section at one end of the pipe is smaller than the outer diameter of the pipe; the end of the pipe that has not been ground is the socket section. Both the socket section and the spigot section are punched so that each end of the pipe can be bolted to the joint more smoothly.

[0005] However, when grinding and punching pipes, a chuck is usually used to clamp one end of the pipe, and a long grinding head is used to press against the outer wall of the other end of the pipe. Then the chuck drives the pipe to rotate, and the grinding head is controlled to feed along the length of the pipe to grind the outer wall of the pipe. After the grinding is completed, holes are punched at both ends of the pipe. Since the chuck only fixes one end of the pipe, the other end of the pipe may be offset during the punching process due to loose fixation. Summary of the invention

[0006] In order to improve the accuracy of the punching position, the present application provides a punching device and a manufacturing process for a football goal tube.

[0007] In the first aspect, the present application provides a punching device for a football goal tube adopting the following technical solution: A punching device for a football goal tube comprises a machine tool, wherein a fixed bracket and a movable bracket are installed on the machine tool, a driving mechanism for driving the movable bracket to move is installed on the machine tool, a chuck for clamping one end of the tube is installed on the side of the fixed bracket close to the movable bracket, a grinding knife assembly for grinding the outer diameter of the tube is installed on the side of the movable bracket close to the fixed bracket, the punching mechanism for punching the end of the tube is fixedly connected to the fixed bracket and the movable bracket, a reinforcement mechanism is also installed on the side of the movable bracket close to the fixed bracket, the reinforcement mechanism comprises a reinforcement support fixedly connected to the movable bracket, two through holes are provided on the bottom surface of the reinforcement support, a connecting rod is inserted in each through hole, a fixed rod is fixedly connected between the lower ends of the two connecting rods, a locking rod is hinged on the upper end of one of the connecting rods, the locking rod extends in the direction of the other connecting rod, a lifting assembly for driving the fixed rod to rise and fall is installed on the reinforcement support, and the reinforcement mechanism also comprises a limiting assembly for limiting the locking rod from rotating upward.

[0008] By adopting the above technical solution, during the working process, first clamp one end of the pipe through the chuck, so that the other end of the pipe contacts the grinding knife assembly and is inserted between the locking rod, two connecting rods and the reinforcement support. Next, the chuck is used to drive the pipe to rotate relative to the grinding knife assembly, and at the same time, the driving mechanism drives the movable bracket and the grinding knife assembly to move in the direction close to the chuck to achieve uniform grinding of the outer diameter of the pipe. Then, start the lifting assembly to drive the fixed rod, two connecting rods and the locking rod to descend. At this time, the limiting assembly comes into play to ensure that the locking rod can stably press the pipe downward to reduce the displacement of the pipe during the processing. Finally, the punching mechanism is adjusted to accurately punch holes at both ends of the pipe to improve the accuracy of the punching position. The entire process has a high degree of automation, which improves production efficiency and product quality.

[0009] Preferably, a pair of mounting blocks are fixedly connected to the upper end of one of the connecting rods, a mounting shaft is rotatably connected between the pair of mounting blocks, the mounting shaft passes through the locking rod and is fixedly connected to the locking rod, both ends of the mounting shaft are sleeved with torsion springs, one end of each torsion spring is fixedly connected to the locking rod, and the other end is fixedly connected to a corresponding mounting block, the limiting assembly includes a limiting rod hinged to the upper end of the other connecting rod, the lower surface of the limiting rod abuts against the upper surface wall of the locking rod, and the limiting assembly includes a locking member for locking the limiting rod and the corresponding connecting rod.

[0010] By adopting the above technical solution, the fixed connection between the installation shaft and the locking rod and the design of the torsion spring 1 enable the locking rod to rotate freely between the installation blocks and maintain a certain initial position when not acted upon by external forces. The limiting rod abuts against the locking rod, which limits the locking rod from rotating upward. During operation, the pipe is abutted against the upper surface of the locking rod and pushed downward. At this time, the locking rod rotates downward, and the pipe can smoothly enter between the two connecting rods. When the pipe moves downward to disengage from the locking rod, the locking rod rotates upward and resets under the action of the torsion spring 1. At this time, the lifting assembly is started to drive the fixing rod, the two connecting rods and the locking rod to descend until the locking rod presses the pipe. The limiting rod limits the locking rod from rotating upward, so that the pipe can be pressed and fixed.

[0011] When the pipe processing is completed, the lifting assembly is started to drive the fixed rod, two connecting rods and the locking rod to rise, and then the locking piece is adjusted to unlock the limit rod. The limit rod is turned upward, and the upward movement of the pipe can push the locking rod to turn upward, making it easier for the pipe to escape from between the two connecting rods.

[0012] Preferably, a pair of limiting blocks are fixedly connected to the upper end of the connecting rod connecting the limiting rod, and a limiting shaft is rotatably connected between the pair of limiting blocks, the limiting shaft passes through the limiting rod and is fixedly connected to the limiting rod, two torsion springs are hinged at both ends of the limiting rod, each end of the two torsion springs is fixedly connected to the limiting rod, and the other end is fixedly connected to a corresponding limiting block, and a pair of locking blocks are fixedly connected to one side wall of the connecting rod connecting the limiting rod, and the locking member includes a first locking rod rotatably connected between the pair of locking blocks, a torsion spring three is installed between the first locking rod and each locking block, and a clamping block is fixedly connected to one end of the first locking rod away from the locking block, and a clamping groove is provided on one side wall of the limiting rod, and the clamping block is clamped with the clamping groove.

[0013] By adopting the above technical solution, during the working process, when it is necessary to unlock the limit rod, the first locking rod is rotated in a direction away from the limit rod, so that the clamping block is disengaged from the clamping groove, and the torsion spring 2 is in a force storage state. Both the locking rod and the limit rod can be rotated, and the method of locking and unlocking the limit rod is relatively simple and convenient.

[0014] Preferably, one end of the first locking rod close to the locking block is fixedly connected to the second locking rod, one end of the second locking rod away from the locking block is fixedly connected to magnet block 1, and one side wall of the connecting rod connected to the limiting rod is fixedly connected to magnet block 2, and when magnet block 1 and magnet block 2 are attracted to each other, the clamping block disengages from the clamping groove.

[0015] By adopting the above technical solution, when the locking state of the limiting rod needs to be released, it is only necessary to rotate the first locking rod and the second locking rod until the clamping block is separated from the clamping groove and the first magnet block and the second magnet block are mutually attracted. At this time, the limiting rod is contacted and locked, and the clamping block can remain separated from the clamping groove, thereby simplifying the unlocking operation and improving work efficiency.

[0016] Preferably, a lever is fixedly connected to the upper surface of the reinforcement support, which extends vertically upward and has an elastic block fixedly connected to the upper end. When the lifting assembly drives the fixed rod to rise, the elastic block drives the second locking rod to rotate downward. When the lifting assembly drives the fixed rod to descend, the elastic block drives the first locking rod to rotate upward.

[0017] By adopting the above technical solution, the design of the lever and the elastic block can effectively realize the automatic control of the second locking rod and the first locking rod. When the lifting assembly drives the fixed rod to rise, the elastic block will push the second locking rod to rotate downward, so that the clamping block will be separated from the clamping groove, and the magnet block 1 and the magnet block 2 will be attracted to each other, releasing the locking state between the limiting rod and the connecting rod; and when the lifting assembly drives the fixed rod to descend, the elastic block will push the first locking rod to rotate upward, and the magnet block 1 will be separated from the magnet block 2, and under the action of the torsion spring 2, the clamping block will be re-engaged in the clamping groove and restored to the locked state. In this way, the automatic locking and automatic unlocking of the limiting rod can be completed without manual operation of the locking member.

[0018] Preferably, the reinforcement support includes two reinforcement plates fixedly connected to the movable bracket, a base is provided between the two reinforcement plates, and vertically arranged long holes are opened on the side surfaces of the two reinforcement plates close to each other, a screw is inserted in each long hole, one end of each screw is threadedly connected to the base, and the other end of each bolt is provided with a nut, and the nut is used to tighten the side surface of the corresponding reinforcement plate away from the base.

[0019] By adopting the above technical solution, the design of the long hole allows the screw and the base to be adjusted up and down within a certain range so as to adapt to pipes of different lengths or diameters, thereby increasing the scope of application of the equipment.

[0020] Preferably, a mounting frame is fixedly connected to the upper surface of the movable bracket, and the grinding knife assembly includes a cutting tool fixedly connected to a side of the mounting frame close to the reinforcement mechanism, and a receiving groove is provided on a side of the cutting tool close to the reinforcement mechanism, the opening of the receiving groove is flared, and a grinding knife surface is provided at the opening of the receiving groove.

[0021] By adopting the above technical solution, the mounting frame fixedly connected to the upper surface of the mobile bracket can stably support the grinding knife assembly to ensure stability during the grinding process. A receiving groove is provided on the side of the tool close to the reinforcement mechanism. The opening of the receiving groove is flared, which can effectively guide the pipe into the grinding area and improve the processing accuracy. A grinding knife surface is provided at the opening of the receiving groove, which can grind the pipe efficiently and evenly during the grinding process, thereby improving product quality and production efficiency.

[0022] Preferably, a side surface of the fixed bracket close to the chuck is provided with a placement groove for inserting one end of the pipe material, each of the punching mechanisms includes a punching knife and a control component for driving the punching knife to rise and fall, the upper surface of the fixed bracket is provided with a perforation 1 connected to the placement groove, the upper surface of the tool is provided with a perforation 2 connected to the receiving groove, one of the punching knives is slidably inserted into the punching hole 1, and the other punching knife is slidably inserted into the punching hole 2.

[0023] By adopting the above technical solution, during the working process, first use the chuck to clamp one end of the pipe to ensure the stability of the pipe. Then, the other end of the pipe is placed in the placement groove and gradually contacts the grinding knife surface. When the driving mechanism drives the movable bracket and the grinding knife assembly on it to move toward the fixed bracket, the chuck drives the pipe to rotate at the same time. At this time, the grinding knife surface accurately grinds the outer diameter of the pipe until the outer diameter of the ground end of the pipe becomes smaller and is inserted into the receiving groove. When the grinding work is completed, the punching knife on the fixed bracket punches one end of the pipe through perforation pair one, and the punching knife on the tool punches the other end of the pipe through perforation pair two. The whole process not only improves the work efficiency, but also punches one end of the pipe under the fixation of the chuck, and the other end of the pipe is punched under the support of the inner wall of the receiving groove. At the same time, the reinforcement mechanism fixes the pipe, which improves the accuracy of the punching position.

[0024] In the second aspect, the manufacturing process of a punching device for a football goal tube provided by the present application adopts the following technical solution: A manufacturing process of a punching device for a football goal tube comprises the following steps: S1. Clamp one end of the pipe by a chuck, and the other end of the pipe contacts the grinding knife assembly. At the same time, the pipe is inserted between the locking rod, two connecting rods and the reinforcement support; S2, the chuck drives the pipe to rotate relative to the grinding knife assembly, and the driving mechanism drives the movable bracket and the grinding knife assembly to move toward the chuck until one end of the pipe is ground; S3, start the lifting assembly to drive the fixing rod, two connecting rods and the locking rod to descend until the locking rod presses the pipe downward, and at the same time adjust the limiting assembly to lock the locking rod; S4. Adjust the punching mechanism to punch holes at both ends of the pipe.

[0025] By adopting the above technical solution, one end of the pipe is firmly clamped by the chuck to ensure the stability of the pipe in the subsequent processing; at the same time, the other end of the pipe contacts the grinding knife assembly and is inserted between the locking rod, two connecting rods and the reinforcement support, further enhancing the fixing effect of the pipe. The chuck drives the pipe to rotate relative to the grinding knife assembly, so that the grinding is carried out evenly, and the grinding surface quality of the pipe is improved.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. The locking rod can stably press the pipe downward to reduce the deviation of the pipe during processing. Then, the punching mechanism is adjusted to accurately punch holes at both ends of the pipe to improve the accuracy of the punching position. 2. The limit rod can be automatically locked and unlocked without manual operation of the locking piece; 3. Grind the pipes efficiently and evenly to improve product quality and production efficiency.

The opening of the receiving groove 311 is expanded, and the side wall of the expanded portion of the receiving groove 311 is set as a grinding tool surface 312.

[0040] When one end of the pipe is inserted into the expanded opening of the receiving groove 311, the pipe rotates relative to the tool 31. At this time, the grinding blade 312 grinds the outer wall of the pipe until the outer diameter of the pipe is reduced and inserted into the bottom wall of the receiving groove 311, thus completing the grinding of the pipe.

[0045] Reference Figure 1 and Figure 4The reinforcement mechanism 5 includes a reinforcement support 51 fixedly connected to the mobile bracket 12. The reinforcement support 51 includes two reinforcement plates 511 fixedly connected to the upper surface of the mobile bracket 12, and the two reinforcement plates 511 are vertically arranged upward with a base 512 arranged between the two reinforcement plates 511. The two reinforcement plates 511 are provided with vertically arranged long holes 5111 on the side close to each other, and two screws are inserted in each long hole 5111, and one end of each screw is threadedly connected to the corresponding base 512, and the other end of each bolt is provided with a nut, which is used to tighten the side of the corresponding reinforcement plate 511 away from the base 512.

[0046] The screws are rotated so that each nut contacts and tightens against the corresponding reinforcing plate 511 , so that the base 512 can be vertically moved relative to each reinforcing plate 511 , thereby adjusting the height of the base 512 .

[0047] Reference Figure 4 and Figure 5 The upper surface of the base 512 is provided with an arc surface for overlapping the pipe material, and the bottom surface of the base 512 is provided with two through holes, each of which vertically penetrates the base 512, and a connecting rod 52 is inserted into each through hole. A fixing rod 53 is fixedly connected between the lower ends of the two connecting rods 52, and a locking rod 54 is hinged at the upper end of one of the connecting rods 52, and the locking rod 54 extends in the direction of the other connecting rod 52. A lifting assembly 55 for driving the fixing rod 53 to rise and fall is installed on the base 512, and the reinforcement mechanism 5 also includes a limiting assembly 56 for limiting the locking rod 54 from rotating upward.

[0048] A pair of mounting blocks 541 are fixedly connected to the upper end of one of the connecting rods 52, and a mounting shaft 542 is rotatably connected between the pair of mounting blocks 541. The mounting shaft 542 passes through one end of the locking rod 54, and the mounting shaft 542 is fixedly connected to the locking rod 54. Torsion springs 543 are sleeved at both ends of the mounting shaft 542, and one end of each torsion spring 543 is fixedly connected to the locking rod 54, and the other end is fixedly connected to a corresponding mounting block 541.

Torsion springs 564 are sleeved at both ends of the limiting shaft 563, and one end of each torsion spring 564 is fixedly connected to the limiting rod 561, and the other end is fixedly connected to a corresponding limiting block 562. The limiting assembly 56 includes a locking member 565 for locking the limiting rod 561 with the corresponding connecting rod 52.

[0050] Place the pipe above the locking rod 54 and press against the upper surface of the locking rod 54, and push the pipe downward. At this time, the pipe pushes the locking rod 54 to rotate downward until the pipe enters between the two connecting rods 52. The pipe continues to move downward until it contacts the upper surface of the base 512. During this process, the pipe is separated from the locking rod 54, and the locking rod 54 is rotated upward by the force of the torsion spring 543 until it contacts the limiting rod 561. Then, the fixing rod 53, the two connecting rods 52, and the locking rod 54 are driven down by the lifting assembly 55 until the locking rod 54 presses against the pipe on the base 512, thus completing the locking of the pipe. In order to better lock the pipe, a layer of rubber pad is fixedly connected to the lower surface of the locking rod 54.

[0051] When the pipe is processed, the locking piece 565 is adjusted to contact the limiting rod 561, and the limiting rod 561 is rotated upward. The limiting rod 561 is disengaged from the locking rod 54, and the pipe is pulled upward to push the locking rod 54 to rotate upward until the pipe is separated from the reinforcement mechanism 5.

A torsion spring 3 5652 is installed between the first locking rod 5651 and each locking block 566. When the torsion spring 3 5652 is not subjected to external force, the first locking rod 5651 remains in a vertically upward state.

When the first magnet block 5655 and the second magnet block 5656 are mutually adsorbed, the clamping block 5653 is separated from the clamping groove.

[0054] The upper surface of the reinforcement support 51 is fixedly connected with a lever 6 , which is arranged vertically upwards. The upper end of the lever 6 is fixedly connected with an elastic block 61 , and one end of the elastic block 61 close to the locking piece 565 is arranged in a pointed shape.

[0055] When the lifting assembly 55 drives the fixing rod 53 to rise, the elastic block 61 pushes the second locking rod 5654 to rotate downward. At this time, the magnet block 1 5655 is rotated toward the direction close to the magnet block 2 by the adsorption force of the magnet block 2, until the magnet block 1 and the magnet block 2 5656 are adsorbed on each other, the clamping block 5653 is separated from the clamping groove, and the limiting rod 561 is contacted and locked.

[0056] When the lifting assembly 55 drives the fixing rod 53 to descend, the elastic block 61 moves the first locking rod 5651 to rotate upward. At this time, the second magnet block 5656 is separated from the first magnet block 5655, and the clamping block 5653 is clamped with the clamping groove, and the limiting rod 561 is locked, thus realizing the automatic control of the locking rod 54, further improving the intelligence of the system.

[0057] Reference Figure 5 The lifting assembly 55 includes a lifting motor 551 fixedly connected to the bottom surface of the base 512. The output shaft of the lifting motor 551 is vertically arranged downward and coaxially fixed with a screw rod 552.
