Description

Technical Field

[0001] This invention relates to the field of steel ball extrusion technology, and more specifically, to a steel ball extrusion device for ring bars. Background Technology

[0002] After the ring bar product is drilled by multiple axes, in order to ensure the consistency of its hole diameter and surface roughness, it is generally set up on a punch press to perform extrusion operation on each hole with tungsten carbide balls. This is also considered a relatively efficient processing method at present.

[0003] The ring bar product has a thin-walled, dendritic shape, and its outer surface is rough with poor uniformity, making it unsuitable for automated operations using robotic arms. Manual loading and unloading are generally required. Furthermore, each ring bar weighs 5-8 kg, and completing the extrusion process requires multiple simultaneous handling of the workpiece and tungsten carbide balls, resulting in extremely high labor intensity. Many employees cannot perform a normal 8-hour workday using these processing methods, leading to a rapid increase in labor costs. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a high-efficiency ring bar extrusion device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This invention discloses a steel ball extrusion device for ring bars, comprising a support platform, wherein the support platform is equipped with a clamping mechanism, an extrusion mechanism, and a steel ball conveying mechanism.

[0007] The clamping mechanism includes a first support plate mounted on a support platform and extending along the X direction, a second support plate extending along the Z direction connected to the first support plate, and movable first and second clamping members mounted on the second support plate.

[0008] The extrusion mechanism includes a first extrusion group mounted on a first support plate and a second extrusion group mounted on a support platform. The first extrusion group includes two first support members capable of moving along the X and Y directions. The second extrusion group includes two second support members capable of moving along the Y and Z directions. Both the first and second support members are equipped with a first telescopic rod capable of moving along the Y direction and a first power source for driving the first telescopic rod. Both the first and second support members are also equipped with a support block. The support block has a telescopic channel penetrating through it. The support block is provided with a clearance groove, which divides the telescopic channel into a first telescopic channel and a second telescopic channel arranged along the extension direction of the first telescopic rod. A waiting device is installed in the clearance groove. The waiting device includes a feeding channel concentrically arranged with the telescopic channel and a waiting channel communicating with the feeding channel. A receiving device is connected to the outlet of the second telescopic channel. The receiving device is connected to a discharge channel. The discharge channel and the waiting channel are connected to the steel ball conveying mechanism through a pipe.

[0009] Furthermore, the first support plate is connected to a bearing plate, and the bearing plate is connected to a bearing block extending to a position corresponding to the location of the relief groove. The bearing block is equipped with a retractable bearing rod extending toward the relief groove.

[0010] Furthermore, the clearance groove includes a first surface and a second surface arranged along the extension direction of the first telescopic rod, the telescopic channel forms a first opening on the second surface, and an insert is provided at the first opening that is partially embedded in the first opening.

[0011] Furthermore, a limiting ring is provided at the first opening to partially cover the end of the insert to restrict the movement of the insert. The limiting ring is connected to a fastening groove. The support block is provided with a limiting block. The limiting block is provided with a connecting hole that passes through the limiting block. A second fastener connected to the fastening groove passes through the connecting hole. A second stop block with a diameter larger than the second fastener is provided at the end of the second fastener away from the fastening groove. A second spring is sleeved on the second fastener and is placed between the limiting block and the second stop block.

[0012] Furthermore, both the first and second support members are slidably connected to the slide rail. The slide rail is detachably equipped with a clamping block. The clamping block is provided with a second telescopic hole. A third telescopic rod passes through the second telescopic hole. One end of the third telescopic rod is connected to the first power source, and the other end is provided with a third stop. The third telescopic rod is fitted with a third spring and a fourth spring. The third spring is placed between the clamping block and the third stop, and the fourth spring is placed between the clamping block and the first power source.

[0013] Furthermore, the clamping block includes a block-shaped body and a U-shaped hook-shaped body. The block-shaped body and the hook-shaped body form a clamping opening through which the slide rail passes. One end of the hook-shaped body is fixed to the block-shaped body, and the other end of the hook-shaped body is left with a gap and is fixed by a fourth fastener so that the tightness of the fourth fastener can adjust the size of the gap and thus adjust the friction between the clamping opening and the slide rail.

[0014] Furthermore, the first clamping member is connected to a first adjusting plate, and the second clamping member is connected to a second adjusting plate. Both the first and second adjusting plates are provided with a plurality of adjusting holes. The two ends of the transmission plate are respectively rotatably connected to the adjusting holes of the first and second adjusting plates. The support plate is equipped with a second telescopic rod and a second power source for driving the second telescopic rod to move. The first clamping member is equipped with an abutment corresponding to the position of the second telescopic rod. The second telescopic rod extends out and abuts against the abutment to restrict the movement of the first and second clamping members.

[0015] Furthermore, the transmission plate has grooves at both ends, and the first adjusting plate and the second adjusting plate are respectively embedded in the grooves at both ends. The sidewall of the groove is provided with a positioning hole, and the positioning hole and the adjusting hole are connected by a pin. The pin passes through the positioning hole and the adjusting hole. The transmission plate is equipped with a third fastener, and the end of the third fastener abuts against the end of the pin to restrict the movement of the pin.

[0016] The beneficial effects of this invention are:

[0017] 1. By using four extrusion stations corresponding to the four holes of the ring bar, extrusion operations can be performed on all four holes simultaneously, which improves efficiency, ensures the accuracy of extrusion, and reduces the labor intensity of workers.

[0018] 2. The ring bar is clamped by a clamping mechanism, and the ring bar is supported by a bearing rod, which enables the ring bar to adaptively adjust its position so that the hole of the ring bar corresponds to the telescopic channel, thereby ensuring the extrusion accuracy.

[0019] 3. The insert can evenly distribute the pressure on the ring bar during extrusion, thereby preventing the ring bar from shifting during extrusion and ensuring extrusion accuracy. Attached Figure Description

Detailed Implementation

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] See Figures 1 to 14 A punching device for a circular ring bar 700 includes a support platform 100, on which are mounted a clamping mechanism for supporting the circular ring bar 700, a punching mechanism for punching holes in the circular ring bar 700, and a steel ball conveying mechanism for conveying steel balls for punching. The circular ring bar 700 includes a connecting pipe 710 and rocker arms 720 mounted at both ends of the connecting pipe 710. Each rocker arm 720 includes connecting ends 721 extending in two directions, and connecting holes 273 are provided on the connecting ends 721. Therefore, a single circular ring bar 700 has four holes requiring punching operations.

[0037] The clamping mechanism includes a first support plate 400 and a second support plate 410. The first support plate 400 extends along the X direction, and the second support plate 410 is fixed to the first support plate 400 and extends along the Z direction. A first clamping member and a second clamping member are mounted on the second support plate 410. The first clamping member includes a first movable plate 500, which is slidably connected to the second support plate 410. A first clamping plate 501 extending along the X direction is fixed to the first movable plate 500. The second clamping plate 511 includes a second movable plate 510 slidably connected to the second support plate 410, and a second clamping plate 511 moving along the X direction is fixed to the second movable plate 410. The first movable plate 500 and the second movable plate 510 are arranged vertically. The first clamping plate 501 is fixed to the left side of the first movable plate 500, and the second clamping plate 511 is fixed to the right side of the second movable plate 510. The annular plate is clamped between the first clamping plate 501 and the second clamping plate 511. The distance between the first clamping plate 501 and the second clamping plate 511 can be adjusted by moving the first movable plate 500 and the second movable plate 510, thereby accommodating annular bars 700 of different sizes.

[0038] A first adjusting plate 502 is connected to a first clamping member, and a second adjusting plate 512 is connected to a second clamping member. Both the first adjusting plate 502 and the second adjusting plate 512 have multiple adjusting holes 503. A rotatable transmission rod is mounted on a second support plate 410. The two ends of the transmission rod are rotatably connected to the adjusting holes 503 of the first adjusting plate 502 and the second adjusting plate 512, respectively, so that the movement of the first moving plate 500 can drive the second moving plate 510 to move in the opposite direction. By connecting the transmission plate 520 to the adjusting holes 503 at different positions, the maximum relative movement distance between the first moving plate 500 and the second moving plate 510 can be adjusted, thus accommodating ring bars 700 of different lengths.

[0039] An abutment 411 is installed on the top of the first support plate 400, and a second telescopic rod 413 and a second power source 412 for driving the second telescopic rod 413 are installed on the top of the second support plate 410. Specifically, the second power source 412 is a cylinder, and the second telescopic rod 413 is the output rod of the cylinder. The second telescopic rod 413 can abut against the abutment 411 to restrict the movement of the first and second moving plates 510, thereby keeping the first clamping plate 501 and the second clamping plate 511 clamping the corresponding ring rod 700. When the ring rod 700 needs to be loaded or unloaded, the second telescopic rod 413 retracts, the abutment against the abutment 411 disappears, and the first moving plate 500 and the second moving plate 510 can move relative to each other. The distance between the first clamping plate 501 and the second clamping plate 511 can be appropriately increased, so that the first clamping plate 501 and the second clamping plate 511 can release the ring rod 700, facilitating the picking and placing of the ring rod 700.

[0040] A support assembly is also installed on the support platform 100. The support includes a third support plate placed between the first clamping plate 501 and the second support plate. Two placement plates are fixed on the third support plate. The placement plates are provided with V-shaped grooves, and the ring rod 700 is placed in the V-shaped grooves.

[0041] The extrusion mechanism includes a first extrusion group 101 and a second extrusion group 102. The first extrusion group 101 includes two first support members 200, and the second extrusion group 102 includes two second support members 201. Each first support member 200 and each second support member 201 is equipped with a first telescopic rod 210 and a first power source 211 for driving the first telescopic rod 210. Specifically, the first power source 211 is a hydraulic cylinder, which is powered by a hydraulic station 103. The first telescopic rod 210 is a rod connected to the output end of the hydraulic cylinder. The first telescopic rods 210 of the two first support members 200 are arranged opposite each other, and the first telescopic rods 210 of the two second support members 201 are arranged opposite each other, thus forming four extrusion stations, which correspond to the positions of the four holes in the ring bar 700. Meanwhile, each of the first support member 200 and the second support member 201 is provided with a support block 220. The support block 220 is provided with a telescopic channel through which the first telescopic rod 210 passes. At the same time, the support block 220 is also provided with a clearance groove 221. The clearance groove 221 cuts off the telescopic channel, dividing the telescopic channel into a first telescopic channel 222 and a second telescopic channel 223. The first telescopic channel 222 and the second telescopic channel 223 are arranged along the extension direction of the first telescopic rod 210.

[0042] The bottom of the first support plate 400 is connected to a fixed plate 401 via a slider and slide rail 420. The first support plate 400 is also fixedly connected to the support platform 100 via a fixed rod 402, allowing the fixed plate 401 to move in the X direction. The end of the fixed plate 401 is connected to the slide rail 420. The first support member 200 of the first extrusion assembly 101 is connected to the slide rail 420 at the end of the fixed plate 401 via a slider, allowing the first extrusion assembly 101 to move in both the X and Y directions. This ensures that the clearance groove 221 aligns with the hole on the ring bar 700, guaranteeing the accuracy of the extrusion.

[0043] The second support member 201 of the second extrusion group 102 is connected to the support platform 100 through a structure in which the slider and the slide rail 420 cooperate, so that the second extrusion group 102 can move along the Z and Y directions, and the relief groove 221 of the second extrusion group 102 can be aligned with the hole on the ring bar 700 to ensure the accuracy of extrusion.

[0044] A waiting device 230 is installed in the clearance groove 221. The waiting device 230 includes a feeding channel 231 concentrically arranged with the telescopic channel and a waiting channel 232 communicating with the feeding channel 231. The steel ball conveying mechanism is connected to the opening of the waiting channel 232 through the pipe 610, so that the steel ball can enter the conveying channel through the waiting channel 232. A recess 233 corresponding to the position of the waiting channel 232 is provided on the side wall of the conveying channel. The recess 233 can limit the steel ball in the conveying channel, thereby preventing the steel ball from moving under the pressure of the steel ball in the waiting channel 232 when it is not pushed by the first telescopic rod 210.

[0045] A first support plate 400 is connected to a bearing plate 300. The bearing plate 300 is connected to a bearing block 310 extending to a position corresponding to the location of the relief groove 221.

[0046] The clearance groove 221 includes a first surface 2211 and a second surface 2212 arranged along the extension direction of the first telescopic rod 210. The telescopic channel forms a first opening 2213 on the second surface 2212. An insert 250 is provided at the first opening 2213, which is partially embedded in the first opening 2213. A limiting ring 260 is provided at the first opening 2213 to partially cover the end of the insert 250 to restrict the movement of the insert 250. The limiting ring 260 is connected to a fastening groove 261. The support block 220 is provided with a limiting block 270. The limiting block 270 is provided with a connecting hole 273 that passes through the limiting block 270. A second fastener 271 connected to the fastening groove 261 passes through the connecting hole 273. A second stop block 274 with a diameter larger than the fastener is provided at the end of the second fastener 271 away from the fastening groove 261. A second spring 272 is sleeved on the second fastener 271 and placed in the connecting hole 273. The second spring 272 is placed between the limiting block 270 and the second stop block 274.

[0047] Clamping elements 430 are installed on the slide rails 420 connected to the first support member 200 and the second support member 201. The clamping block is provided with a second telescopic hole 444. A third telescopic rod 440 passes through the second telescopic hole 444. One end of the third telescopic rod 440 is connected to the first power source 211, and the other end is provided with a third stop 443. A third spring 441 and a fourth spring 442 are sleeved on the third telescopic rod 440. The third spring 441 is placed between the clamping block and the third stop 443, and the fourth spring 442 is placed between the clamping block and the first power source 211. The clamping block includes a block-shaped body 431 and a U-shaped hook-shaped body 432. The block-shaped body 431 and the hook-shaped body 432 form a clamping opening 434 through which the slide rail 420 passes. One end of the hook-shaped body 432 is fixed to the block-shaped body 431, and the other end of the hook-shaped body 432 is left with a gap 433 between it and the block-shaped body 431 and is fixed by fasteners so that the tightness of the fasteners can adjust the size of the gap 433, thereby adjusting the friction between the clamping opening 434 and the slide rail 420.

[0048] The first clamping member is connected to the first adjusting plate 502, and the second clamping member is connected to the second adjusting plate 512. Both the first adjusting plate 502 and the second adjusting plate 512 are provided with a plurality of adjusting holes 503.

The second telescopic rod 413 extends out and abuts against the abutment member 411 to restrict the movement of the first clamping member and the second clamping member.

[0049] The transmission plate 520 has grooves 523 at both ends. The first adjusting plate 502 and the second adjusting plate 512 are respectively embedded in the grooves 523 at both ends. The side wall of the groove 523 is provided with positioning holes 524. The positioning holes 524 and the adjusting holes 503 are connected by pins 521. The pins 521 pass through the positioning holes 524 and the adjusting holes 503. The transmission plate 520 is equipped with a third fastener 522.
