Technical Field

[0001] The utility model relates to the technical field of cold heading machines, in particular to a material-rejecting casting for a cold heading machine. Background Art

[0002] Cold heading machine is a stamping machine widely used in mechanical manufacturing, mainly used for producing metal parts such as bolts, nuts, screws, etc. Cold heading machine needs to push the material during operation, so a pusher casting is used. Among them, the "a kind of return casting for cold heading machine" disclosed by the publication number "CN214720275U" has solved the technical disadvantage that the return mechanism in the machine is often fixed in structure, and it is very inconvenient to replace the new return mechanism. However, in actual use, there are still many defects in the return casting of similar structure. For example, only the parts of a single mold can be pushed out and returned during one operation. When encountering parts that need multiple cold heading processes, multiple groups need to be used in combination. The overall performance is poor when multiple groups are used in combination, and a larger working space is required when multiple groups are used in combination. The stability is poor when multiple groups are used in combination, and it is easy to fail during long-term operation. For this reason, we have designed a return casting for cold heading machine to solve the above problems. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a material stripping casting for a cold heading machine, which solves the problem that when stripping metal parts that have been subjected to multiple cold heading processes, multiple sets of castings need to be used in conjunction, resulting in large occupied space and high failure rate.

[0004] To achieve the above purpose, the utility model is implemented through the following technical solutions: a stripping casting for a cold heading machine, comprising a mounting mechanism and a pushing mechanism assembled inside the mounting mechanism, the mounting mechanism comprising an assembly plate, four sets of sliding sleeves are fixedly mounted inside the assembly plate, and a fixing frame is fixedly mounted at the bottom of the assembly plate;

[0005] The pushing mechanism includes a pushing cylinder and three groups of pushing auxiliary rods. The bottoms of the outer walls of the three groups of pushing auxiliary rods are fixedly installed with limiting rings, the bottoms of the three groups of pushing auxiliary rods are slidably installed with sliding rods, the bottoms of the three groups of sliding rods are fixedly installed with threaded tubes threadedly installed on the fixing frame, the tops of the three groups of threaded tubes are fixedly installed with pushing springs that abut against the bottom of the limiting rings, the output end of the pushing cylinder is fixedly installed with a pushing main rod, the tops of the pushing main rod and the three groups of pushing auxiliary rods are fixedly installed with pushing pins, the tops of the four groups of pushing pins are threadedly installed with strike plates, the tops of the four groups of strike plates are fixedly installed with rubber buffer pads, the outer wall of the pushing main rod is provided with a mounting ring plate, and a contact sensor is fixedly installed on one side of the mounting ring plate.

[0006] Preferably, an adjusting sleeve is fixedly mounted on the inner wall of the mounting ring plate, and a locking shaft is threadedly mounted on the front surface of the adjusting sleeve.

[0007] Preferably, three groups of threaded sleeves corresponding to the three groups of limiting rings are fixedly installed at the bottom of the installation mechanism, and threaded limiting rods are bolted inside the three groups of threaded sleeves.

[0008] Preferably, an operating disk is fixedly mounted on the bottom of the three groups of threaded tubes, and an operating panel is fixedly mounted on the bottom of the three groups of operating disks.

[0009] Preferably, fixing plates are fixedly installed on both sides of the assembly plate, and a shock-absorbing rubber pad is fixedly installed on the top of the assembly plate.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-6 The utility model provides a technical solution: a material stripping casting for a cold heading machine, comprising a mounting mechanism 1 and a pusher mechanism 2 assembled inside the mounting mechanism 1, the mounting mechanism 1 comprising an assembly plate 101, four sets of sliding sleeves 107 are fixedly mounted inside the assembly plate 101, a fixing frame 104 is fixedly mounted at the bottom of the assembly plate 101, the pusher mechanism 2 comprises a pusher cylinder 201 and three sets of pusher auxiliary rods 3, the bottoms of the outer walls of the three sets of pusher auxiliary rods 3 are all fixedly mounted with limiting rings 301, the bottoms of the three sets of pusher auxiliary rods 3 are all slidably mounted with slide rods 302, and the bottoms of the three sets of slide rods 302 are all fixedly mounted with threaded mountings On the threaded tube 304 on the fixed frame 104, the tops of the three groups of threaded tubes 304 are fixedly installed with pushing springs 303 that abut against the bottom of the limiting ring 301, the output end of the pushing cylinder 201 is fixedly installed with a pushing main rod 202, the tops of the pushing main rod 202 and the three groups of pushing auxiliary rods 3 are fixedly installed with pushing pins 4, the tops of the four groups of pushing pins 4 are threadedly installed with impact plates 401, the tops of the four groups of impact plates 401 are fixedly installed with rubber buffer pads 402, the outer wall of the pushing main rod 202 is provided with a mounting ring plate 203, and a contact sensor 206 is fixedly installed on one side of the mounting ring plate 203.

[0022] Based on the above-mentioned structural setting, the stripping casting for the cold heading machine is composed of a mounting mechanism 1 and a pushing mechanism 2, wherein the mounting mechanism 1 is a mounting and fixing mechanism for the stripping casting, with the aid of the mounting mechanism 1, the stripping casting can be lowered and installed in the cold heading machine, and the pushing mechanism 2 is a pushing and stripping mechanism for the cold heading machine when processing parts. Specifically, during the working process, the assembly plate 101 can be installed inside the cold heading machine, and three groups of pushing auxiliary rods 3 are respectively slidably installed inside the sliding sleeves 107 on the assembly plate 101, and the three groups of threaded tubes 304 can limit the path of the pushing auxiliary rod 3 when it slides up and down through the corresponding sliding rods 302, and the pushing mechanism 2 can be used to push the stripping auxiliary rod 3 to the inner sleeve 107 of the assembly plate 101. The material spring 303 is sleeved on the outside of the sliding rod 302, and the top and bottom of the pushing spring 303 are respectively in conflict with the threaded tube 304 and the limiting ring 301, so that the pushing spring 303 can elastically support the pushing auxiliary rod 3, and the tops of the three groups of pushing auxiliary rods 3 are fixedly installed with pushing strikers 4 extending into the cold heading machine mold, so that the pushing spring 303 can elastically support and reset the pushing auxiliary rod 3 so that the pushing striker 4 can perform mold opening on the parts in the mold, which is convenient for the cold heading machine's material moving mechanism to move the parts to the subsequent forming mold. At the same time, by rotating the threaded tube 304, the pushing auxiliary rod 3 and the pushing material can be moved. The striker 4 adjusts the moving distance of the parts in the mold, which is convenient for the staff to adjust and control according to the material moving mechanism of the cold heading machine. The push cylinder 201 can slide and lift the push main rod 202 in the sliding sleeve 107 by extending. The push striker 4 installed on the top of the push main rod 202 can completely push out the parts after processing and forming in the cold heading machine mold when the push main rod 202 is raised, thereby realizing the function of automatic pushing and withdrawing of the cold heading machine, avoiding the situation where the parts that need to be processed and formed in multiple processes cannot be withdrawn or the situation where the stability is poor and the failure rate is high due to the use of multiple groups of castings. The plate 401 and the rubber buffer pad 402 can provide flexible protection when the impact pin pushes out the parts, and the removal of the impact plate 401 makes it easy for the staff to replace it later, ensuring the stability of the push pin 4 during long-term use. The contact sensor 206 installed on the mounting ring plate 203 can detect the height of the push main rod 202 when it is raised. The extension length of the push cylinder 201 during operation can be adjusted by moving the contact sensor 206, so that the push main rod 202 and the push pin 4 can be controlled when the parts of the mold are completely pushed out, thereby improving the stability of the withdrawn casting during operation.

[0023] Furthermore, an adjustment sleeve 204 is fixedly mounted on the inner wall of the mounting ring plate 203, and a locking shaft 205 is threadedly mounted on the front surface of the adjustment sleeve 204. The adjustment sleeve 204 can slide and adjust the mounting ring plate 203 and the contact sensor 206, and the locking shaft 205 can lock the mounting ring plate 203 when it is moved and adjusted, thereby ensuring the stability of the contact sensor 206 when it is in operation.

[0024] Furthermore, three sets of threaded sleeves 5 corresponding to the three sets of limiting rings 301 are fixedly installed at the bottom of the mounting mechanism 1, and threaded limiting rods 501 are bolted inside the three sets of threaded sleeves 5. The threaded limiting rods 501 can interfere with the limiting rings 301 when the push rod 3 moves, so that the height of the push rod 3 when it is extended can be limited by the threaded limiting rods 501, and the threaded limiting rods 501 can be rotated in the threaded sleeves 5 to adjust the limiting height of the push rod 3.

[0025] Further, the bottom of the three groups of threaded tubes 304 are all fixedly installed with operating disks 305, and the bottom of the three groups of operating disks 305 are all fixedly installed with operating panels 306. Among them, the operating disks 305 and the operating panels 306 facilitate the rotation operation of the threaded tubes 304 when the staff adjusts them.

[0026] Furthermore, a fixing plate 102 is fixedly installed on both sides of the assembly plate 101, and a shock absorbing rubber pad 103 is fixedly installed on the top of the assembly plate 101. The fixing plate 102 can fix the assembly plate 101 by bolts, and the shock absorbing rubber pad 103 can buffer and reduce shock when the casting is installed, and improve the firmness of the casting during installation.

[0027] Furthermore, a closing plate 105 is fixedly mounted on the front and back of the fixing frame 104, and a pull ring 106 is fixedly mounted on the surface of the two sets of closing plates 105. The closing plates 105 can close and protect the front and back of the fixing frame 104, and the pull ring 106 facilitates the staff to disassemble and install the closing plates 105 later.
