Description

Technical Field

[0001] This utility model relates to the field of mechanical parts processing technology, specifically to an extrusion device for processing mechanical parts. Background Technology

[0002] A mechanical parts processing extrusion device is a pressure processing equipment that uses a punch or die to apply pressure to a blank, causing it to plastically flow and be shaped. It typically includes core components such as a machine base, a clamping mechanism, and an extrusion mechanism.

[0003] Traditional extrusion devices lack a structure for limiting and guiding the material during extrusion. This makes them prone to friction with the die exit during extrusion, resulting in a higher risk of scratches or roughening. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides an extrusion device for processing mechanical parts. The device has a structure that can limit and guide the material during extrusion, making it less likely to rub against the die outlet during extrusion, thus effectively reducing the risk of scratches or roughening.

[0005] The technical solution adopted by this utility model to solve its technical problem is an extrusion device for processing mechanical parts, including a base, an electric hydraulic cylinder, a clamp, an extrusion die and a conveyor belt mechanism. The conveyor belt mechanism is provided at one end of the top of the base. The extrusion die is installed on the top of the conveyor belt mechanism near the center through a first mounting frame. The electric hydraulic cylinder is provided on the top of the base away from the conveyor belt mechanism through a second mounting frame. The power output end of the electric hydraulic cylinder is connected to the clamp.

[0006] A support leg is provided at the top of the base near the first mounting frame and the conveyor belt mechanism. A U-shaped frame plate is connected to the top of the support leg. A material guiding mechanism is provided on the inner wall of the U-shaped frame plate near all four sides. The material guiding mechanism includes a fixed plate, a guide sleeve, a guide rod, a U-shaped plate and a rubber contact wheel. A lead rod is provided on the top of the fixed plate through a threaded hole. A handle is provided at the end of the lead rod. A bushing is provided on the outer periphery of the other end of the lead rod, and a U-shaped plate is connected to the end of the bushing. A rubber contact wheel is provided on the inner wall of the U-shaped plate through a rotating shaft. A guide sleeve is provided at the bottom of the fixed plate near both ends. A guide rod is sleeved inside the guide sleeve. The bottom of the guide rod is connected to the top of the U-shaped plate.

[0007] By adopting the above technical solution, the metal bar material to be extruded is clamped by the clamper. The metal bar material moves horizontally under the drive of the electric hydraulic cylinder, enters the feeding end of the extrusion die, and is formed into the required shape by the extrusion force, and is discharged through the discharge port of the extrusion die.

[0008] Specifically, an extension plate is connected to one end of the U-shaped plate near the top, and a camera is mounted on the bottom of the extension plate via a fixing seat.

[0009] By adopting the above technical solution, the camera is fixedly installed through the explosion-proof lighting of the extension plate. The camera can be used to conveniently record the defects on the outer wall of the extruded metal parts. Personnel can view the surface defects of the parts by watching the monitoring screen connected to its signal.

[0010] Specifically, the inner wall of the U-shaped frame plate is provided with reinforcing ribs near the corners.

[0011] Specifically, the feed port of the extrusion die is aligned with the center height of the clamp.

[0012] Specifically, the conveyor belt mechanism consists of a mounting frame, guide rollers, and a conveyor belt body. Two sets of guide rollers are respectively arranged inside the mounting frame near both ends. The conveyor belt body is arranged around the guide rollers. A drive motor is arranged at one end of the conveyor belt mechanism near the top through a mounting plate.

[0013] By adopting the above technical solution, a conveyor belt mechanism can be easily assembled using a mounting frame, guide rollers, and conveyor belt body. The conveyor belt mechanism can receive and further transport metal parts after they have passed through the material guiding mechanism, making it convenient to transport them to the next process.

[0014] Specifically, the power output end of the drive motor is connected to one of the sets of guide rollers.

[0015] Specifically, a cylindrical spring is connected to the outer wall of the guide rod, and one end of the cylindrical spring is connected to the bottom of the guide sleeve.

[0016] By adopting the above technical solution, through the cylindrical spring, guide sleeve and guide rod, the rubber contact wheel has the degree of freedom in the axial direction of the guide sleeve when subjected to force, which can achieve tight clamping when the rubber contact wheel contacts the outer surface of the metal part without crushing the part.

[0017] Specifically, the handle is covered with an anti-slip sleeve made of EVA material.

[0018] The beneficial effects of this utility model are:

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] To ensure that this extrusion device has a limiting and guiding structure during extrusion, reducing the risk of scratches or burrs caused by friction with the die exit during extrusion, such as... Figure 1-5 As shown, the extrusion device for processing mechanical parts according to the present invention includes a base 1, an electric hydraulic cylinder 6, a clamp 7, an extrusion die 3, and a conveyor belt mechanism 4. The conveyor belt mechanism 4 is provided at one end of the top of the base 1. The extrusion die 3 is installed on the top of the conveyor belt mechanism 4 near the center via a first mounting bracket 2. The electric hydraulic cylinder 6 is provided on the top of the base 1 away from the conveyor belt mechanism 4 via a second mounting bracket 5. The power output end of the electric hydraulic cylinder 6 is connected to the clamp 7.

[0029] A support leg 8 is provided at the top of the base 1 near the first mounting frame 2 and the conveyor belt mechanism 4. A U-shaped frame plate 9 is connected to the top of the support leg 8. A material guiding mechanism 10 is provided on the inner wall of the U-shaped frame plate 9 near all four sides. The material guiding mechanism 10 includes a fixed plate 11, a guide sleeve 12, a guide rod 13, a U-shaped plate 19 and a rubber contact wheel 20. A lead rod 15 is provided at the top of the fixed plate 11 through a threaded hole. A handle 16 is provided at the end of the lead rod 15. A bushing is provided on the outer periphery of the other end of the lead rod 15 and the end of the bushing is connected to the U-shaped plate 19. A rubber contact wheel 20 is provided on the inner wall of the U-shaped plate 19 through a rotating shaft. A guide sleeve 12 is provided at the bottom of the fixed plate 11 near both ends. A guide rod 13 is sleeved on the inner side of the guide sleeve 12. The bottom of the guide rod 13 is connected to the top of the U-shaped plate 19.

[0030] In use, the metal bar material to be extruded is clamped by the clamp 7. The metal bar material moves horizontally under the drive of the electric hydraulic cylinder 6 and enters the feed end of the extrusion die 3. It is then formed into the required shape by the extrusion force and discharged through the discharge port of the extrusion die 3.

[0031] For example, such as Figure 3-4 As shown, the present invention also includes an extension plate 17 connected to one end of the U-shaped plate 19 near the top, and a camera 18 is mounted on the bottom of the extension plate 17 via a fixing seat.

[0032] In use, the camera 18 is fixedly installed by the explosion-proof lighting of the extension plate 17. The camera 18 is used to conveniently record the defects on the outer wall of the extruded metal parts. Personnel can view the surface defects of the parts by watching the monitoring screen connected to its signal.

[0033] For example, such as Figure 5 As shown, the present invention also includes reinforcing ribs 21 provided on the inner wall of the spiral frame plate 9 near the corners.

[0034] When in use, the overall strength of the spiral frame plate 9 can be effectively improved by reinforcing rib 21.

[0035] For example, such as Figure 1-2 As shown, the present invention also includes that the feed port of the extrusion die 3 is flush with the center height of the clamp 7.

[0036] When in use, since the center height of the clamp 7 is flush with the feed port of the extrusion die 3, the metal raw material clamped by the clamp 7 can be effectively fed.

[0037] For example, such as Figure 1-2As shown, the present invention also includes a conveyor belt mechanism 4 consisting of a mounting frame, guide rollers and a conveyor belt body. Two sets of guide rollers are respectively arranged inside the mounting frame near both ends. A conveyor belt body is arranged around the guide rollers. A drive motor 22 is arranged at one end of the conveyor belt mechanism 4 near the top through a mounting plate.

[0038] In use, the mounting frame, guide rollers and conveyor belt body can be easily assembled into a conveyor belt mechanism 4. The conveyor belt mechanism 4 can be used to receive and further transport the metal parts after they have passed through the material guiding mechanism 10, so as to facilitate their transport to the next process.

[0039] For example, such as Figure 1-2 As shown, the present invention also includes a power output end of the drive motor 22 connected to one of the guide rollers.

[0040] In use, the drive motor 22 can easily drive the guide roller to rotate, thereby driving the conveyor belt to rotate.

[0041] For example, such as Figure 3 As shown, the present invention also includes a cylindrical spring 14 connected to the outer wall of the guide rod 13, and one end of the cylindrical spring 14 is connected to the bottom of the guide sleeve 12.

[0042] In use, the cylindrical spring 14, guide sleeve 12 and guide rod 13 enable the rubber contact wheel 20 to have the axial direction of the guide sleeve 12 when subjected to force, so that it can achieve tight clamping when the rubber contact wheel 20 contacts the outer surface of the metal part without crushing the part.

[0043] For example, such as Figure 3 As shown, the present invention also includes an anti-slip sleeve on the outer side of the handle 16, the anti-slip sleeve being made of EVA material.

[0044] When in use, the anti-slip sleeve made of EVA material has a good anti-slip effect, which can effectively prevent slippage when the handle 16 is subjected to external force.

[0045] In use, the electric hydraulic cylinder 6, the gripper 7, the drive motor 22, and the camera 18 are all connected to an external power source. The electric hydraulic cylinder 6, as the actuator of the complete external hydraulic system, is installed in this device. The metal bar to be processed is fed to the gripping end of the gripper 7 by an external robotic arm.

[0046] The metal bar material to be extruded is held by the clamp 7. The metal bar moves horizontally under the drive of the electric hydraulic cylinder 6 and enters the feed end of the extrusion die 3. It is then shaped into the required shape by the extrusion force and discharged through the discharge port of the extrusion die 3.

[0047] By applying external force to the handle 16, the operator can easily rotate the lead screw 15, thereby causing the bushing and U-shaped plate 19 to move along the axial direction of the guide sleeve 12 and the guide rod 13. After discharge, the rubber contact wheel 20 set on the inner wall of the U-shaped plate 19 contacts the outer wall of the formed metal part, realizing the limiting and guiding function of the metal part during discharge. Through the columnar spring 14, the guide sleeve 12 and the guide rod 13, the rubber contact wheel 20 has the freedom in the axial direction of the guide sleeve 12 when subjected to force. It can achieve tight clamping when the rubber contact wheel 20 contacts the outer surface of the metal part without crushing the part. This extrusion device has a structure that can limit and guide the material during extrusion. It is not easy to generate friction with the mold outlet during extrusion, which can effectively reduce the risk of scratches or scratches.
