Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wire drawing die processing technology, specifically relating to a grinding head for wire drawing dies. Background Technology
[0002] A wire drawing die is a mold specifically used for metal wire drawing production. The inside of the wire drawing die has small holes with specific diameters and shapes. The wire is pulled through the wire drawing die by external force, thereby drawing the wire into a wire of a specific shape and thickness. The inner hole of the wire drawing die core needs to be ground to a specific diameter during the processing. The grinding process uses a grinding head to drive the grinding needle to mill and grind the wire drawing die.
[0003] The existing wire drawing die head is rigidly installed and uniformly connected. Since the wire drawing die itself is made of high-hardness and high-wear-resistant material, the rigidly installed processing head is prone to breaking the grinding needle during the grinding process. Therefore, it is necessary to design a new type of wire drawing die grinding head. Summary of the Invention
[0004] The purpose of this invention is to provide a grinding head for wire drawing dies to solve the problems mentioned in the background art regarding the use of existing wire drawing die processing.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a grinding head for wire drawing dies, comprising a metal fixing plate, two sets of fixedly installed metal connecting plates are provided on the front side of the metal fixing plate, a head bracket is provided at the center of the two sets of metal connecting plates, the head bracket and the metal connecting plate are fixedly connected by four sets of first flexible shafts, and a grinding head is connected to the bottom side of the head bracket by a second flexible shaft.
[0006] Preferably, the machine head support has two sets of grooves, one upper and one lower, and the four sets of first flexible shafts are arranged in pairs on both sides of the two sets of grooves.
[0007] Preferably, the two sets of first flexible shafts on the upper side extend into the interior of the groove, and the ends of the two sets of first flexible shafts are connected by a ring sleeve, which is fixedly installed on the metal fixing plate by bolts.
[0008] Preferably, a fixing block is provided in the lower groove, the second flexible shaft is fixedly installed on the fixing block, and a grinding needle is provided on the grinding head.
[0009] Preferably, the first flexible shaft and the second flexible shaft are made of hard rubber.
[0010] Preferably, a shock-absorbing spring is installed on the top of the metal fixing plate, and an elastic connecting plate is connected to the rear side of the top of the metal fixing plate.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] Both the first and second flexible shafts are made of hard rubber with a certain strength. Under normal use, the first and second flexible shafts can provide a support connection to ensure the normal operation of the grinding head. When the grinding needle is subjected to stress, the first and second flexible shafts can undergo elastic deformation to absorb energy. By absorbing the stress transmitted by the grinding needle through deformation, the first and second flexible shafts can effectively protect the grinding needle, prevent it from breaking under stress, and thus extend the service life of the grinding needle.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Reference Figure 1 A grinding head for wire drawing dies includes a metal fixing plate 1. Two sets of fixedly installed metal connecting plates 2 are provided on the front side of the metal fixing plate 1. A head bracket 3 is provided at the center of the two sets of metal connecting plates 2. The head bracket 3 and the metal connecting plate 2 are fixedly connected by four sets of first flexible shafts 4. A grinding head 9 is connected to the bottom side of the head bracket 3 by a second flexible shaft 8.
[0017] To address the problem that the existing grinding head 9 is rigidly connected, making the grinding needle 10 prone to breakage during processing, this technical solution proposes a novel grinding head. Specifically, the grinding head 9 is mounted on the head support 3 via a second flexible shaft 8. The head support 3 is mounted on a metal connecting plate 2 via four sets of first flexible shafts 4. During grinding, the grinding needle 10 is subjected to significant stress, which can be transferred to the first flexible shafts 4 and the second flexible shafts 8. The first flexible shafts 4 and the second flexible shafts 8 absorb the stress transferred by the grinding needle 10 through deformation, effectively protecting the grinding needle 10 and preventing it from breaking under stress.
[0018] In this technical solution, the first flexible shaft 4 and the second flexible shaft 8 are distinguished from rigid connecting shafts. It does not mean that the first flexible shaft 4 and the second flexible shaft 8 are soft and malleable. Essentially, the first flexible shaft 4 and the second flexible shaft 8 are rubber rollers that can deform under force. Under normal conditions, they have a certain degree of hardness and strength. The deformation of the first flexible shaft 4 and the second flexible shaft 8 is small, thereby maintaining the installation stability of the grinding head 9 and the head support 3. The slight deformation of the first flexible shaft 4 and the second flexible shaft 8 can prevent the grinding needle 10 from directly and rigidly colliding with the wire drawing die, thereby effectively protecting the grinding needle 10 and extending its service life.
[0019] Furthermore, the head support 3 is provided with two sets of grooves 5, one above the other, and four sets of first flexible shafts 4 are arranged in pairs on both sides of the two sets of grooves 5.
[0020] With this technical solution, the head support 3 is set on the center line of the two sets of metal connecting plates 2. One end of the first flexible shaft 4 is fixed on the metal connecting plate 2, and the other end is fixed to the head support 3. Through the four sets of first flexible shafts 4, the head support 3 can be fixedly installed. The first flexible shaft 4 can deform when the head support 3 is subjected to force, thereby absorbing stress and preventing the grinding needle 10 from breaking under force.
[0021] Furthermore, the two sets of first flexible shafts 4 on the upper side extend into the interior of the groove 5, and the ends of the two sets of first flexible shafts 4 are connected by a ring sleeve 6, which is fixedly installed on the metal fixing plate 1 by bolts.
[0022] Through this technical solution, the two sets of first flexible shafts 4 on the upper side penetrate into the interior of the tank 5, and are connected by a ring 6. The ring 6 is fixed to the metal fixing plate 1 by bolts, thus providing central support, so that the head support 3 will not shift significantly due to force. The ring 6 fixation to a certain extent limits the head support 3, preventing the grinding head 9 from shifting excessively, thereby ensuring the stability of the grinding head 9.
[0023] Furthermore, a fixing block 7 is provided in the lower groove 5, the second flexible shaft 8 is fixedly installed on the fixing block 7, and a grinding needle 10 is provided on the grinding head 9.
[0024] In this design, the second flexible shaft 8 is vertically mounted on the fixed block 7, the grinding head 9 is mounted on the second flexible shaft 8, the grinding needle 10 is fixedly mounted on the grinding head 9, and the grinding head 9 is also equipped with a drive device that drives the grinding needle 10 to move at high speed. The drive device drives the grinding needle 10 to move, thereby grinding the wire drawing die.
[0025] Furthermore, the first flexible shaft 4 and the second flexible shaft 8 are made of hard rubber.
[0026] The first flexible shaft 4 and the second flexible shaft 8 are made of hard rubber, which ensures the strength of the first flexible shaft 4 and the second flexible shaft 8. At the same time, the materials of the first flexible shaft 4 and the second flexible shaft 8 can deform and absorb energy, thereby protecting the grinding needle 10.
[0027] Furthermore, a shock-absorbing spring 11 is installed on the top of the metal fixing plate 1, and an elastic connecting plate 12 is connected to the rear side of the top of the metal fixing plate 1.
[0028] Through this technical solution, both the shock-absorbing spring 11 and the elastic connecting plate 12 are used to absorb the vibration of the metal fixing plate 1, keep the shape of the metal fixing plate 1 stable and undeformed, and thus ensure the stability of the entire grinding head 9.
[0029] Working principle: Compared with the traditional rigid connection installation of the grinding head 9, the grinding head 9 of this solution is mounted on the head support 3 using a second flexible shaft 8. The head support 3 is mounted on the metal connecting plate 2 using multiple first flexible shafts 4. Both the first flexible shafts 4 and the second flexible shafts 8 are made of hard rubber with a certain strength. Under normal use, the first flexible shafts 4 and the second flexible shafts 8 can provide a support connection to ensure the normal operation of the grinding head 9. When the grinding needle 10 is subjected to stress, the first flexible shafts 4 and the second flexible shafts 8 can undergo elastic deformation to absorb energy. The first flexible shafts 4 and the second flexible shafts 8 can absorb the stress transmitted by the grinding needle 10 through deformation, which can effectively protect the grinding needle 10, prevent the grinding needle 10 from breaking under stress, and thus improve the service life of the grinding needle 10.
