An automotive parts processing equipment and method

Abstract

This invention discloses an automotive parts processing equipment and method, belonging to the field of automotive parts processing. The equipment includes a frame with two symmetrically arranged material-receiving rollers rotatably connected to it. The rotation of these rollers enables the loading and unloading of a tubular front crossbeam. Each roller is connected to a transmission assembly and slidably connected to a fixed mold core corresponding to a material-receiving slot. During rotation, the transmission assembly drives the fixed mold cores to reciprocate axially. During loading, the fixed mold cores gradually insert into the tubular front crossbeam as the rollers rotate, until the punching hole aligns with the punch position of the moving die. As the rollers continue to rotate, the fixed mold cores gradually withdraw from the tubular front crossbeam, completing the unloading process. Simultaneously, because the movement of the fixed mold cores is synchronized with the loading and unloading of the rollers, the waiting time for the fixed mold cores to insert and withdraw from the tubular front crossbeam is effectively reduced, thereby significantly improving overall production efficiency.

Description

Technical Field

[0001] This invention relates to the field of automotive parts processing, and in particular to an automotive parts processing equipment and method. Background Technology

[0002] Automotive parts are the various units that make up the whole of automotive parts processing and the products that serve automotive parts processing. As an important part of automobiles, automotive parts often require punching during processing.

[0003] For example, Chinese Patent CN120619164B discloses a punching device for a tubular front crossbeam of an automobile. The fixed mold consists of two movable half-molds, with a lifting mechanism in the middle of the movable half-molds. On both sides of the fixed mold, there are feeding mechanisms that deliver the crossbeams to the lifting mechanism one by one, and receiving mechanisms that collect the crossbeams released by the lifting mechanism one by one. A linkage control mechanism is also provided to realize the linkage between the horizontal relative approach or distance of the movable half-molds and the vertical lifting of the lifting mechanism. While performing the punching operation of the tubular front crossbeam of an automobile, the device can automatically deliver the temporarily stored crossbeams one by one to the mold core and realize the positioning and installation with the mold core. It can also realize the automatic detachment of the crossbeams from the mold core and the transfer and temporary storage after detachment. The device has a high degree of automation, which can significantly reduce manpower and improve the continuity and efficiency of the operation.

[0004] However, in the aforementioned prior art, the movement of the two movable half-die requires pulling by the first pull rope, which results in poor reliability over long-term use. Furthermore, before punching and before unloading, it is necessary to wait for the cylinder on the movable half-die to move into place before proceeding to the next step, leading to a long waiting time for the equipment and thus affecting the overall production efficiency. Summary of the Invention

[0005] This invention provides an automotive parts processing equipment that can solve the problem in the prior art where the waiting time for the half-mold to move into place during the loading and unloading process is too long, affecting the overall production efficiency.

[0006] An automotive parts processing equipment includes: a moving mold and a material handling mechanism. The material handling mechanism includes a frame, two symmetrically arranged material handling rollers rotatably connected to the frame, and a drive mechanism for driving the two material handling rollers to rotate synchronously. The circumferential surfaces of the material handling rollers are evenly distributed with a plurality of material handling slots. By placing both ends of a tubular front crossbeam into the material handling slots of the two material handling rollers respectively, the rotation of the material handling rollers enables the loading and unloading of the tubular front crossbeam. A discharge hole is provided at the center of rotation of the material handling rollers, and the bottom surface of the material handling slots... A chip removal hole communicating with the discharge hole is provided; the material picker wheel is connected to a transmission component and a fixed mold core corresponding to the material picker groove is slidably connected, and the fixed mold core has a stamping hole; during the rotation of the material picker wheel, the transmission component drives the fixed mold core to move axially back and forth. During the feeding process, the fixed mold core gradually inserts into the tubular front crossbeam as the material picker wheel rotates, until the stamping hole corresponds to the position of the punch of the moving mold. As the material picker wheel continues to rotate, the fixed mold core gradually rotates out of the tubular front crossbeam, realizing the unloading.

[0007] As a preferred embodiment of the present invention, the transmission assembly includes a lead screw rotatably connected to the material take-up wheel, with a gear fixedly connected to one end of the lead screw; the fixed mold core is connected to a nut that mates with the lead screw; the frame is fixedly connected to an arc-shaped external gear ring and an arc-shaped internal gear ring, which are arranged sequentially along the rotation direction of the material take-up wheel. By rotating the material take-up wheel, the gear meshes sequentially with the arc-shaped external gear ring and the arc-shaped internal gear ring, causing the lead screw to rotate forward and reverse, thereby driving the fixed mold core to move axially back and forth.

[0008] As a preferred embodiment of the present invention, the circumferential surface of the fixed mold core is provided with an axially formed groove, a slide bar is slidably connected in the groove, and a protrusion and a stop block are fixedly connected therein; the slide bar is provided with a stepped hole, and a top pin is movably inserted through the stepped hole, the top pin is arranged parallel to the axial direction of the stamping hole, and a spring is sleeved on the top pin for pushing the top pin into the groove by the spring; a stop block is fixedly connected to the slide bar, and an elastic element is connected between the stop block and the stop block. During the process of the fixed mold core being inserted into the tubular front crossbeam, the stop block abuts against the end face of the tubular front crossbeam, causing the slide bar and the fixed mold core to move axially relative to each other, and the protrusion pushes the top pin outward of the groove, and the top pin abuts against the inner wall of the tubular front crossbeam to fix the position of the tubular front crossbeam.

[0009] As a preferred embodiment of the present invention, the material receiving trough is provided with a settling trough, and a support block is installed in the settling trough. The upper surface of the support block is a curved surface structure adapted to the outer wall of the tubular front crossbeam, and the support block is provided with a downward punching hole corresponding to the position of the chip discharge hole.

[0010] As a preferred embodiment of the present invention, the chip removal hole has a stepped hole structure, and the support block is fixedly connected to a discharge guide that moves through the chip removal hole. The discharge guide is fitted with a return spring and a limit ring is fixedly connected. One end of the return spring abuts against the limit ring, and the other end abuts against the stepped surface of the chip removal hole, so as to keep the support block in the sink.

[0011] As a preferred embodiment of the present invention, the material receiving groove is provided with a T-shaped groove communicating with the settling trough. A T-shaped block and two push rods are slidably connected in the T-shaped groove. One end of the push rod near the support block has a wedge-shaped structure, and the other end is fixedly connected to a guide rod that moves through the T-shaped block. The guide rod is fitted with a compression spring. The lower surface of the support block has an inclined surface that matches the wedge-shaped structure at the end of the push rod. The fixed mold core is fixedly connected to a top block. During the process of inserting the fixed mold core into the tubular front crossbeam, the top block pushes the T-shaped block, so that the end of the push rod cooperates with the inclined surface of the support block, thereby pushing the support block towards the outside of the settling trough, so that the upper surface of the support block abuts against the outer wall of the tubular front crossbeam.

[0012] As a preferred embodiment of the present invention, the spring has an elastic coefficient of K1, the elastic element has an elastic coefficient of K2, and K2 > K1; the reset spring has an elastic coefficient of K3, the compression spring has an elastic coefficient of K4, and K4 > K3, wherein K2 > K4.

[0013] As a preferred embodiment of the present invention, the discharge hole has a conical hole structure, and a discharge pipe is fixedly connected to the end face of the material taking wheel. The discharge pipe is located at the enlarged end of the discharge hole, and a spiral blade is fixedly connected to the inner wall of the discharge pipe.

[0014] As a preferred embodiment of the present invention, the frame includes two symmetrically arranged mounting brackets, and two material handling wheels are rotatably connected to the two mounting brackets respectively; the material handling wheels are fixedly connected to a gear ring; the drive mechanism includes a spline shaft and a spline sleeve that cooperate with each other, the spline shaft and the spline sleeve are rotatably connected to the two mounting brackets respectively, and both the spline shaft and the spline sleeve are fixedly connected to a drive gear that meshes with the gear ring, and the spline shaft or the spline sleeve is driven by a drive motor.

[0015] A method for processing automotive parts includes the following steps: Step S100: By setting a chute, the tubular front crossbeam rolls towards the material pick-up wheel position until both ends are engaged in the material pick-up groove; by rotating the two material pick-up wheels synchronously, the tubular front crossbeam is transferred to the stamping position to realize material loading, and during the rotation of the material pick-up wheel, the transmission component drives the fixed mold core to gradually insert into the tubular front crossbeam. Step S200: When the tubular front crossbeam is directly below the punch of the moving die, the take-up roller stops and the punch is used to punch holes in the tubular front crossbeam. Step S300: After punching is completed, the two material take-up rollers rotate synchronously, and when the material take-up rollers rotate to the point where the opening of the material take-up groove faces downward, the tubular front crossbeam after punching rolls out of the material take-up groove by itself to realize material unloading.

[0016] The present invention has the following beneficial effects: This invention utilizes a transmission assembly to drive the fixed mold core to reciprocate axially during the rotation of the pick-up wheel. This allows the fixed mold core to gradually insert into the tubular front crossbeam as the pick-up wheel rotates, and to gradually withdraw from the tubular front crossbeam as the pick-up wheel continues to rotate, thus achieving unloading. This synchronizes the movement of the fixed mold core with the loading and unloading of the pick-up wheel, effectively reducing the time the equipment spends waiting for the fixed mold core to insert and withdraw from the tubular front crossbeam, thereby significantly improving overall production efficiency.

Detailed Implementation

[0019] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0020] Example 1 like Figures 1 to 3 As shown in the figure, an automotive parts processing equipment provided by an embodiment of the present invention includes a moving mold 10 and a material handling mechanism. The specific structure of the moving mold 10 can be implemented with reference to the prior art. The material handling mechanism includes a frame 1, which is rotatably connected to two symmetrically arranged material handling rollers 2, and a drive mechanism connected to drive the two material handling rollers 2 to rotate synchronously.

[0021] Specifically, the frame 1 includes two symmetrically arranged mounting brackets 11, and two material-collecting rollers 2 are rotatably connected to the two mounting brackets 11 respectively. A gear ring 214 is fixedly connected to each material-collecting roller 2. The drive mechanism includes a splined shaft 12 and a splined sleeve 13 that cooperate with each other. The splined shaft 12 and the splined sleeve 13 are rotatably connected to the two mounting brackets 11 respectively, and both the splined shaft 12 and the splined sleeve 13 are fixedly connected to a drive gear 14 that meshes with the gear ring 214. A drive motor 15 is driven by either the splined shaft 12 or the splined sleeve 13. The drive motor 15 is mounted on one of the mounting brackets 11 via a motor bracket. The drive motor 15 drives the splined shaft 12 and the splined sleeve 13, thereby utilizing the meshing of the drive gear 14 and the gear ring 214 to synchronously drive the two material-collecting rollers 2 to rotate.

[0022] Two mounting brackets 11 can be slidably mounted on the base so that the distance between the two mounting brackets 11 can be adjusted according to the length of the workpiece to be processed. The spline shaft 12 and spline sleeve 13 are used in a matching manner, which will not affect the adjustment process of the distance between the two mounting brackets 11, thus facilitating adaptive adjustment according to the length of the tubular front crossbeam being processed.

[0023] like Figures 3-6 As shown, four material picking grooves 201 are evenly distributed on the circumferential surface of the material picking wheel 2. The cross-section of the material picking groove 201 is U-shaped. The depth of the material picking groove 201 is equal to or slightly greater than the diameter of the tubular front crossbeam, so that the material picking groove 201 can only accommodate one tubular front crossbeam 5.

[0024] Two chutes are set between two mounting brackets 11, one of which is used for feeding. The tubular front crossbeams 5 are arranged side by side on this chute. Due to the inclined setting of the chutes, the tubular front crossbeams 5 can roll towards the material pick-up wheel 2 on their own. When the material pick-up wheel 2 rotates to the position where the material pick-up groove 201 is opposite to the position of the tubular front crossbeams 5, the two ends of the tubular front crossbeams 5 are respectively placed in the material pick-up grooves 201 of the two material pick-up wheels 2. As the material pick-up wheel 2 rotates, the tubular front crossbeams 5 are rotated to the stamping processing position to complete the feeding.

[0025] Another chute is located below the material pick-up wheel 2. As the material pick-up wheel 2 rotates, the stamped tubular front crossbeam 5 rotates to the other side under the drive of the material pick-up wheel 2. When the opening of the material pick-up chute 201 faces downward, the tubular front crossbeam 5 rolls into the chute by itself, realizing automatic material unloading.

[0026] like Figure 4 , Figure 6 and Figure 8 As shown, the rotating center of the material take-up roller 2 is provided with a discharge hole 202, and the bottom surface of the material take-up groove 201 is provided with a chip removal hole 203 that communicates with the discharge hole 202. The material take-up roller 2 is connected to a transmission component, and is slidably connected to a fixed mold core 3 that corresponds one-to-one with the material take-up groove 201. The fixed mold core 3 is provided with a stamping hole 301.

[0027] The material-taking roller 2 has a stepped shaft structure on its circumference, with a mounting hole concentric with the material-taking groove 201 at the shoulder. The fixed mold core 3 slides within the mounting hole. The transmission assembly includes a lead screw 204 rotatably connected to the material-taking roller 2, with a gear 205 fixedly connected to one end of the lead screw 204. A mounting groove can be formed in the inner wall of the mounting hole, with the lead screw 204 located within the mounting groove and one end extending out of the groove, where the gear 205 is mounted. By mounting the lead screw 204 within the mounting groove, the overall volume can be effectively reduced. The fixed mold core 3 is welded with an ear plate, which is connected to a nut that mates with the lead screw 204. Thus, the rotation of the lead screw 204 drives the fixed mold core 3 to move axially.

[0028] The frame 1 is fixedly connected to the arc-shaped external gear ring 101 and the arc-shaped internal gear ring 102 by the bracket. The arc-shaped external gear ring 101 and the arc-shaped internal gear ring 102 are arranged sequentially along the rotation direction of the material pick-up wheel 2, and are both coaxial with the material pick-up wheel 2.

[0029] By rotating the material handling wheel 2, the gear 205 sequentially meshes with the arc-shaped external gear ring 101 and the arc-shaped internal gear ring 102, causing the lead screw 204 to rotate forward and reverse, thereby driving the fixed mold core 3 to move axially back and forth. During the rotation of the material take-up roller 2, the fixed mold core 3 is driven to move axially back and forth using the transmission component.

[0030] like Figure 4 , Figure 9 and Figure 10 As shown, during the feeding process, the material take-up wheel 2 rotates counterclockwise. When the gear 205 meshes with the arc-shaped external gear ring 101, the tubular front crossbeam 5 is inserted into the material take-up groove 201. As the material take-up wheel 2 rotates, the material take-up wheel 2 drives the gear 205 to roll along the arc-shaped external gear ring 101. By rotating the lead screw 204, the fixed mold core 3 is driven to move into the tubular front crossbeam 5, so that the fixed mold core 3 is gradually inserted into the tubular front crossbeam 5 as the material take-up wheel 2 rotates.

[0031] When the material take-up wheel 2 drives the tubular front crossbeam 5 to rotate until the punching hole 301 corresponds to the position of the punch of the moving die, the tubular front crossbeam 5 is in the stamping processing position, the opening of the material take-up groove 201 is vertically upward, the moving die moves down, and the punch is used to punch the tubular front crossbeam 5. The waste material after punching enters the discharge hole 202 through the chip discharge hole 203.

[0032] After the punching process is completed, as the material take-up wheel 2 continues to rotate, the gear 205 moves to mesh with the arc-shaped internal gear ring 102. At this time, during the rotation of the material take-up wheel 2, the gear 205 drives the lead screw 204 to rotate in the opposite direction, thereby driving the fixed mold core 3 to rotate and gradually pull out the tubular front crossbeam 5. When the opening of the material take-up groove 201 faces downward, the tubular front crossbeam 5 rolls down onto the chute under its own gravity, thereby realizing automatic material unloading.

[0033] By setting up a drive component, the movement of the fixed mold core 3 is synchronized with the loading and unloading of the material pick-up wheel 2, which effectively reduces the time the equipment waits for the fixed mold core 3 to be inserted into and withdrawn from the tubular front crossbeam 5, thereby effectively improving the overall production efficiency.

[0034] In this embodiment, a preferred implementation further includes a tapered discharge hole 202, allowing waste material falling into the discharge hole 202 to automatically move towards one end of the discharge hole 202 for automatic discharge. Furthermore, a discharge pipe 212 is fixedly connected to the end face of the material-receiving wheel 2 via screws. The discharge pipe 212 is located at the enlarged end of the discharge hole 202, and a spiral blade 213 is fixedly connected to the inner wall of the discharge pipe 212. This allows the spiral blade 213 to gradually discharge waste material as the material-receiving wheel 2 drives the discharge pipe 212 to rotate.

[0035] Adding a discharge pipe 212 not only improves the convenience of waste collection, but also avoids the situation where waste is directly discharged and falls, which could easily cause collisions with components such as the fixed mold core 3 and the lead screw 204, thus improving the reliability of use.

[0036] Example 2 like Figures 10-12 As shown, based on Embodiment 1, a groove 302 is axially formed on the circumferential surface of the fixed mold core 3. The groove 302 can be a dovetail groove. A slide bar 303 is slidably connected within the groove 302, and a protrusion 304 and a stop block 305 are fixedly connected within the groove 302 by screws. If an installation slot is formed within the groove 302, the protrusion 304 is installed within the installation slot. The surface of the protrusion 304 facing the slide bar 303 has a curved structure and gradually protrudes from the installation slot.

[0037] The slide bar 303 has a stepped hole through which a top pin 306 is movably inserted. The top pin 306 is parallel to the axial direction of the stamping hole 301, and both ends of the top pin 306 have curved surfaces. A spring 307 is fitted onto the top pin 306, with the lower end of the spring 307 abutting against the stepped surface of the stepped hole. The spring 307 pushes the top pin 306 into the slide groove 302, ensuring that the end of the top pin 306 does not protrude from the slide bar 303.

[0038] The slide bar 303 is screwed or welded to a stop block 308, and an elastic element 309 is connected between the stop block 308 and the stop block 305. For example, the stop block 308 is fixedly connected to two pins, which are movably inserted into the stop block 305. The elastic element 309 can be a cylindrical spring and is sleeved on the pins.

[0039] like Figure 7 As shown, during the process of inserting the fixed mold core 3 into the tubular front crossbeam 5, the stop block 308 abuts against the end face of the tubular front crossbeam 5. When the fixed mold core 3 moves into the tubular front crossbeam 5, the stop block 308 cannot move, causing the slide bar 303 and the fixed mold core 3 to move axially relative to each other. The slide bar 303 drives the ejector pin 306 to move, and pushes the ejector pin 306 towards the outside of the slide groove 302 through the protrusion 304. Thus, the ejector pin 306 abuts against the inner wall of the tubular front crossbeam 5, thereby fixing the position of the tubular front crossbeam 5. This effectively prevents the tubular front crossbeam 5 from jumping during punching and punch removal, which is beneficial to improving the stability of punching.

[0040] Example 3 like Figures 8-10As shown, based on Embodiment 2, a sink 206 is provided in the material receiving trough 201. The sink 206 has a rectangular structure and a support block 4 is installed in the sink 206. The upper surface of the support block 4 is a curved structure that is adapted to the outer wall of the tubular front crossbeam. The support block 4 is provided with a lower punching hole 401 corresponding to the position of the chip discharge hole 203. The support block 4 can be replaced when the position of the lower punching hole 401 is worn.

[0041] Meanwhile, the chip removal hole 203 has a stepped hole structure. The support block 4 is welded or screwed to a discharge guide 402 that moves through the chip removal hole 203. The discharge guide 402 is fitted with a return spring 403 and a limit ring 404 is fixedly connected. One end of the return spring 403 abuts against the limit ring 404, and the other end abuts against the stepped surface of the chip removal hole 203, so as to keep the support block 4 in the sink 206.

[0042] The material receiving trough 201 has a T-shaped groove 207 that communicates with the settling trough 206. A T-shaped block 208 and two push rods 209 are slidably connected in the T-shaped groove 207. One end of the push rod 209 near the support block 4 has a wedge-shaped structure, and the other end is fixedly connected to a guide rod 210 that moves through the T-shaped block 208. A compression spring 211 is sleeved on the guide rod 210.

[0043] The lower surface of the support block 4 has an inclined surface 405 that matches the wedge-shaped structure at the end of the push rod 209. The inclined surface 405 is symmetrically arranged relative to the discharge guide 402. The fixed mold core 3 is fixedly connected to the top block 310 by screws. The top block 310 can also be installed in the slide groove 302.

[0044] like Figure 7 , Figure 10 and Figure 13 As shown, during the process of inserting the fixed mold core 3 into the tubular front crossbeam 5, the top block 310 pushes the T-block 208. The T-block 208 pushes the push rod 209 through the compression spring 211, so that the end of the push rod 209 cooperates with the inclined surface 405 of the support block 4, lifting the support block 4 and pushing the support block 4 towards the outside of the sink 206, so that the upper surface of the support block 4 abuts against the outer wall of the tubular front crossbeam 5. Thus, the support block 4 supports the lower side of the tubular front crossbeam 5, further improving the stability of the punching process.

[0045] The spring constant of spring 307 is K1, and the spring constant of elastic element 309 is K2, with K2 > K1, thus ensuring that the top pin 306 is smoothly pushed out by the protrusion 304. At the same time, the spring constant of return spring 403 is K3, and the spring constant of compression spring 211 is K4, with K4 > K3, so that push rod 209 can smoothly lift support block 4.

[0046] Furthermore, K2 > K4, making the compression spring 211 easier to compress than the elastic element 309. This ensures that when the support block 4 supports the lower side of the tubular front crossbeam 5, the top pin 306 will not retract, thus ensuring that the fixing effect of the top pin 306 on the tubular front crossbeam 5 is not affected, and guaranteeing the overall reliability of use.

[0047] The process of using the processing equipment described above in this application is a method for processing automotive parts, including the following steps: Step S100: By setting a chute, the tubular front crossbeam 5 rolls towards the material pick-up wheel 2. When the material pick-up trough 201 corresponds to the position of the tubular front crossbeam 5, both ends of the tubular front crossbeam 5 are inserted into the material pick-up trough 201.

[0048] By rotating the two pick-up rollers 2 synchronously, the tubular front crossbeam 5 is transferred to the stamping position to realize the feeding. During the rotation of the pick-up rollers 2, the gear 205 rolls along the arc-shaped external gear ring 101, and the screw 204 drives the fixed mold core 3 to move into the tubular front crossbeam 5, so that the fixed mold core 3 is gradually inserted into the tubular front crossbeam 5 as the pick-up rollers 2 rotate.

[0049] Step S200: When the tubular front crossbeam 5 is located directly below the punch of the moving die, the material take-up roller 2 stops rotating and uses the punch to punch holes in the tubular front crossbeam 5.

[0050] Step S300: After punching is completed, the two take-up rollers 2 rotate synchronously and mesh with the arc-shaped internal gear ring 102 through the gear 205. At this time, during the rotation of the take-up rollers 2, the gear 205 drives the lead screw 204 to rotate in the opposite direction, thereby driving the fixed mold core 3 to rotate and gradually pull out the tubular front crossbeam 5. When the take-up rollers 2 rotate to the point where the opening of the take-up groove 201 faces downward, the punched tubular front crossbeam rolls out of the take-up groove 201 by itself, realizing the unloading. Thus, the reciprocating motion of the fixed mold core 3 and the rotation of the take-up rollers 2 for loading and unloading are synchronized, thereby reducing the equipment waiting time and effectively improving the overall production efficiency.

[0051] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
