Description

Technical Field

[0001] The invention relates to the field of automobile parts processing, in particular to a punching machine tool for automobile parts processing. Background Art

[0002] Due to the processing problems of the engine, there will be holes of different sizes on the cylinder block. Some smaller water plugging holes are processing channels during mechanical processing. They are blocked with water plugs after processing, especially the sealing water plugs of the water channels. Some larger water plugging holes are designed to protect the engine body or cylinder head. If the engine is filled with water in winter and the water is forgotten to be drained, the water will swell out first after it freezes, thereby protecting the engine body or cylinder head to a certain extent.

[0003] Usually, the water plug of the engine is punched into a disc or bowl shape with ordinary carbon steel plate, and directly embedded in the process hole to prevent the coolant from leaking out. Although the stamping equipment on the market can complete the stamping of water plugs, due to the lack of protection measures, direct stamping can easily cause damage to the water plug, thereby reducing the qualified rate of the product, and manual loading and unloading will also have many safety hazards.

[0004] Therefore, it is necessary to design a stamping machine tool for automobile parts processing that can effectively protect the stamped parts during the water plugging stamping process, thereby improving the product qualification rate and reducing safety hazards during the stamping process.

DETAILED DESCRIPTION

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] Example 1

[0028] A stamping machine tool for processing automobile parts, such as Figure 1 As shown, it includes: a base frame 1, a support rod 101, a support rod 102, a support platform 104, a support plate 105, an arc-shaped bracket 106, an arc-shaped bracket 107, a stamping mechanism and a buffer rebound component. The support rod 101, the support rod 102, the support platform 104, the arc-shaped bracket 106, the arc-shaped bracket 107 and the buffer rebound component are installed on the upper side of the base frame 1, wherein the support rod 101 is fixedly connected to the middle and upper part of the base frame 1, the support rod 102 is fixedly connected to the upper side of the base frame 1, the support platform 104 is fixedly connected to the right side of the upper end of the base frame 1, the rear side of the support plate 105 is fixedly connected to the front side of the support platform 104, the arc-shaped bracket 106 and the arc-shaped bracket 107 are respectively fixedly connected to both sides of the upper middle part of the base frame 1, the buffer rebound component is arranged between the arc-shaped bracket 106 and the arc-shaped bracket 107, and the stamping mechanism is fixedly connected to the upper end of the support rod 101.

[0029] Before stamping, the staff first places the raw material on top of the buffer rebound component, and then starts the hydraulic cylinder 2. At this time, the downward pressure of the hydraulic cylinder 2 will cooperate with the downward pressure of the buffer rebound component to stamp the raw material into shape. After the stamping is completed, the stamping mechanism will reset, and the buffer rebound component will bounce the stamped finished part up to separate it from the pressure of the buffer rebound component. In this way, the stamped parts can be protected while the stamping is completed, thereby improving the qualified rate of the stamped parts.

[0030] Example 2

[0031] On the basis of Example 1, Figure 2-5As shown, the stamping mechanism includes a hydraulic cylinder 2, a spring 201 and a stamping head 202. The hydraulic cylinder 2 is fixedly connected to the upper end of the support rod 101, and the stamping head 202 is fixedly connected to the lower end of the push rod of the hydraulic cylinder 2. The lower end of the push rod of the hydraulic cylinder 2 can be collapsed. The spring 201 is sleeved on the push rod of the hydraulic cylinder 2, and the spring 201 is in contact with the stamping head 202.

[0032] After the preparation work is completed, the staff will start the hydraulic cylinder 2, which will drive the punch head 202 to press down. When the punch head 202 contacts the original part, it will press down to cause it to deform. After pressing down a certain distance so that the workpiece contacts the internal parts of the buffer rebound component, the punch head 202 will be restricted from pressing down. At this time, the push rod of the hydraulic cylinder 2 will collapse. After the raw material is stamped and formed, the spring 201 will drive the punch head 202 to reset. The hydraulic cylinder 2 resets the raw material and the processing is completed.

[0033] The buffer rebound component includes a forming mold 3, a forming template 301, a round pin 302 and a spring 2 303. The forming mold 3 is fixedly connected to the middle part of the base frame 1. The inside of the forming mold 3 is hollow. The forming mold 3 is located directly below the stamping mechanism. The forming template 301 is located on the forming mold 3. The bottom sides of both ends of the forming template 301 are fixedly connected to the upper side of the base frame 1 through an arc bracket 1 106 and an arc bracket 2 107. The round pin 302 is slidably connected in the forming mold 3, and the spring 2 303 is sleeved on the round pin 302.

[0034] When the punch head 202 drives the raw material downward, the squeezed round pin 302 will slide and shrink into the inside of the forming mold 3. After reaching the limit distance, the punch head 202 will cooperate with the forming template 301 and the forming mold 3 to extrude the raw material into shape. After processing, the punch head 202 is driven to reset by the hydraulic cylinder 2. At this time, the round pin 302 will be rebounded by the spring 2 303, and the finished product will also be lifted up by the round pin 302 and placed at the uppermost end of the forming template 301, thereby protecting the stamped parts.

[0035] Example 3

[0036] On the basis of Example 2, Figure 6-7As shown, the one-way transmission mechanism includes a curved rod 4, a slide rod 401, a support rod 3 402, a rotating shaft 1 403, a ratchet 404, a rotating shaft 2 405, a belt 406 and a pulley 407. The left rear end of the curved rod 4 is fixedly connected to the upper end of the push rod of the hydraulic cylinder 2, and the right front end of the curved rod 4 is provided with a straight rack. The lower end of the slide rod 401 is fixedly connected to the base frame 1, the curved rod 4 slides in the slide rod 401, and the lower end of the support rod 3 402 is fixedly connected to the bottom frame 1. On the base frame 1, the support rod three 402 is close to the slide rod 401, and the upper end of the support rod three 402 is rotatably connected to the rotating shaft one 403, and the rotating shaft one 403 is fixedly connected to the ratchet 404. There are two pulleys 407, and the outer ring of the ratchet 404 is fixedly connected to one of the pulleys 407. The rotating shaft two 405 rotates through the support plate 105 and the support platform 104. The front end of the rotating shaft two 405 is fixedly connected to the pulley 407, and the belt 406 is wrapped around the two pulleys 407.

[0037] When the stamping mechanism is running, the curved rod 4 connected to the push rod of the hydraulic cylinder 2 will also be driven to move. At this time, the curved rod 4 will slide up and down along the slide rod 401. When the curved rod 4 moves upward, it will touch the ratchet 404, and the rack on the curved rod 4 will drive the ratchet 404 to rotate. At this time, the pulley 407 connected to the ratchet 404 will transmit the power to another pulley 407 through the belt 406, and the other pulley 407 will drive the second rotating shaft 405 to rotate. When the curved rod 4 moves downward, the ratchet 404 will idle and will not drive the pulley 407 to rotate, thereby achieving the purpose of one-way power transmission.

[0038] The feeding mechanism includes a rotating wheel 6, a rotating pin 601, a lever 602, a square slider 603, a connecting block 604, an arc-shaped push rod 6041 and a material barrel 605. The rotating wheel 6 is fixedly connected to the rear end of the rotating shaft 2 405. The square slider 603 is fixedly connected to the position of the rotating wheel 6 away from the center of the circle. The rotating pin 601 is fixedly connected to the lower end of the rear side of the support 104. The lever 602 is rotatably connected to the rotating pin 601. A straight groove is opened in the middle of the lever 602. The square slider 603 slides in the straight groove. The upper end of the lever 602 is slidably connected to the connecting block 604. The upper side of the support 104 is slidably connected to the arc-shaped push rod 6041. The right end of the arc-shaped push rod 6041 is fixedly connected to the bottom side of the connecting block 604. The material barrel 605 is fixedly connected to the upper right side of the forming template 301, and the arc-shaped push rod 6041 is slidably connected to the material barrel 605.

[0039] When power is transmitted to the second rotating shaft 405, the second rotating shaft 405 will drive the rotating wheel 6 at the other end to rotate, and the square slider 603 will also be driven by the rotating wheel 6 to move. When the square slider 603 moves along the circumference of the rotating wheel 6, it will drive the lever 602 to rotate along the rotating pin 601, and the connecting block 604 connected to the other end of the lever 602 will drive the arc push rod 6041 to slide along the upper side of the support 104. When the arc push rod 6041 moves toward the barrel 605, the raw materials in the barrel 605 will be pushed forward, so that the raw materials are pushed to the forming template 301 in the stamping area. When the stamping action is carried out, the arc push rod 6041 will return to the initial position, thus completing a loading action.

[0040] When the ratchet wheel 404 rotates one circle, the rotating wheel 6 will also rotate one circle. One circle of the rotating wheel 6 can just make the arc-shaped push rod 6041 do a complete reciprocating motion.

[0041] When the ratchet wheel 404 outputs power, the number of revolutions it makes is the same as the number of revolutions the rotating wheel 6 makes, thus ensuring that material feeding can be performed before each stamping without interfering with the operation of the stamping mechanism.

[0042] It also includes an annular baffle 8 , the right end of which is fixedly connected to the lower left side of the barrel 605 , and the punch head 202 passes through the annular baffle 8 .

[0043] After the punching action is completed, the finished workpiece may be stuck to the punching head 202. At this time, when the punching head 202 is driven to reset by the hydraulic cylinder 2, it will slide along the annular baffle 8. When a workpiece is stuck to the punching head 202, the annular baffle 8 will scrape it off, thus preventing the workpiece from sticking to the punching head 202.

[0044] It also includes a material return mechanism, a gear lever 501, a gear lever 502 and a material receiving box 7. The right end of the Y-shaped rod 5 is fixedly connected to the front side of the arc-shaped push rod 6041. The gear lever 501 and the gear lever 502 are symmetrically arranged on the base frame 1 along the stamping mechanism. The Y-shaped rod 5 slides through the gear lever 501. The Y-shaped rod 5 is slidably connected to the forming template 301, and the material receiving box 7 is placed on the upper left end of the base frame 1.

[0045] When the arc push rod 6041 moves, the Y-shaped rod 5 connected to the side of the arc push rod 6041 will be driven to move, and the Y-shaped rod 5 will slide along the gear rod 501. When the processing is completed, the Y-shaped rod 5 will push the processed finished parts from the forming template 301 to the material receiving box 7, thereby replacing manual work to return the finished parts and reducing safety hazards during the processing.

[0046] The above embodiments are provided for persons familiar with the art to implement or use the present invention. Personnel familiar with the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope of the innovative features mentioned in the claims.
