Description

Technical Field

[0001] This application relates to the technical field of nut manufacturing, and in particular to a production equipment for a cold-forged ball screw drive actuator nut. Background Technology

[0002] Cold heading forming equipment is a specialized processing equipment based on the cold heading process (a processing technology that applies external force to metal materials at room temperature to cause plastic deformation and form the required shape). It is used to form metal billets (such as wire and bar stock) into various metal parts (such as nuts, bolts, rivets, and irregular hardware parts) in one step or in stages through die stamping, upsetting and other methods.

[0003] Cold heading equipment is a "high-efficiency tool" for the mass production of metal parts. Leveraging the advantages of the cold heading process (high efficiency, material saving, and high quality), it is widely used in standard parts manufacturing, the automotive industry, and building hardware. Its core value lies in producing high-strength, high-precision metal parts at the lowest cost and fastest speed.

[0004] In cold pressing, the blanks need to be shaped and punched in sequence. However, manual feeding is mostly used between each step. Workers take out the workpieces that have been processed in the previous process and place them in the next process. During production, people must not be left alone. Someone must be there to pick up the materials. This makes the labor intensity of workers high, the production efficiency low and the degree of automation low. Summary of the Invention

[0005] To improve the production efficiency and automation level of the equipment, this application provides a production equipment for cold heading ball screw driven actuator nuts.

[0006] The technical solution of the production equipment for cold-headed ball screw drive actuator nuts provided in this application is as follows: A production equipment for cold heading ball screw driven actuator nuts includes a frame, a feeding mechanism, and a rotating mechanism. The frame is used to place the workpiece to be processed. The feeding mechanism is connected to the frame and is used to transport the workpiece to be processed to the required process. The rotating mechanism is connected to the frame and is used to rotate the workpiece to be processed by 60°.

[0007] By adopting the above technical solutions, the frame can hold the workpiece to be processed, the feeding mechanism can transport the workpiece to be processed to the required process, and the rotating mechanism can rotate the workpiece to be processed by 60°, thereby improving the production efficiency and automation level of the equipment.

[0008] Preferably, the feeding mechanism includes a sliding seat, a rotating clamp, and a driving assembly. The sliding seat is slidably connected to the frame, and the rotating clamp is connected to the sliding seat. The rotating clamp is provided in several groups, which are evenly distributed along the sliding direction of the sliding seat. There are two rotating clamps in the same group, and the two rotating clamps in the same group are symmetrically distributed along the sliding direction of the sliding seat. The rotating clamp is used to press against the outer wall of the workpiece to be processed.

[0009] By adopting the above technical solution and setting up multiple sets of operating clamps, the workpieces to be processed in multiple processes can be transported simultaneously, thereby improving production efficiency.

[0010] Preferably, the drive assembly includes a first drive cylinder connected to the frame, and the first drive cylinder is used to drive the sliding seat to slide.

[0011] By adopting the above technical solution, the sliding seat is driven to slide by the first drive cylinder, thereby improving the stability of the sliding seat and making the maximum stroke of the piston rod equal to the distance between two adjacent processes, thus improving the reliability of the equipment.

[0012] Preferably, the feeding mechanism further includes a clamping seat and a second drive cylinder. The clamping seat is slidably connected to a sliding seat, and the sliding direction of the clamping seat is perpendicular to the sliding direction of the sliding seat. The second drive cylinder is connected to the sliding seat and is used to drive the clamping seat to slide. The rotating clamp is rotatably connected to the clamping seat, and the rotation axis of the rotating clamp is parallel to the sliding direction of the clamping seat and the sliding seat. The rotating clamp is connected to a guide post, and the sliding seat is provided with a guide groove. The number of guide grooves is the same as the number of guide posts and they correspond one-to-one. The guide posts are slidably embedded in the guide grooves. When the clamping seat is slidably connected to the workpiece to be processed, the two rotating clamps in the same group move closer to each other.

[0013] By adopting the above technical solution, the second drive cylinder drives the clamping seat to slide, which in turn drives the rotating clamp to slide. The guide column slides within the guide column, driving the two rotating clamps in the same group to move closer or further apart, thereby realizing the clamping and placement of the workpiece to be processed, and improving the production efficiency and automation level of the equipment.

[0014] Preferably, the feeding mechanism further includes a first reset member, the number of which is the same as the number of operating clamp groups and corresponds one-to-one. The first reset member is connected between two operating clamps in the same group, and the first reset member causes the operating clamps to tend to move closer to each other.

[0015] By adopting the above technical solution and setting a first reset component, the possibility of the two operating clamps in the same group separating during the process of clamping the workpiece to be processed and conveying it is reduced, thereby improving the reliability of the equipment.

[0016] Preferably, the feeding mechanism further includes a positioning block and a second resetting member. The positioning block is slidably connected to the sliding seat, and the sliding direction of the positioning block is parallel to the rotation axis of the operating clamp. The clamping seat is provided with a positioning groove, which is divided into two groups. The two groups of positioning grooves are distributed at intervals along the sliding direction of the clamping seat. The positioning groove is used for the positioning block to be embedded to achieve a fixed connection between the clamping seat and the sliding seat. The frame is connected with an abutment block. The abutment block has a first chamfer at both ends along the sliding direction of the sliding seat. The first chamfer is used to abut against the positioning block. The second resetting member is connected between the positioning block and the sliding seat. The second resetting member makes the positioning block tend to disengage from the positioning groove.

[0017] By adopting the above technical solution, when the sliding seat slides, the positioning block abuts against the first chamfer and slides along the first chamfer to the upper end of the abutment block, so that the positioning block is embedded in the positioning groove, realizing the fixed connection between the sliding seat and the clamping seat, reducing the possibility that the second drive cylinder will be accidentally driven during the sliding of the sliding seat, causing the operating clamp to contract or open, which will affect the workpiece to be processed in each process, and improving the reliability of the equipment.

[0018] Preferably, there are several positioning blocks, which are distributed at intervals along the sliding direction of the sliding seat. The number of positioning slots in a set is the same as the number of positioning blocks and corresponds one-to-one. The number of the second reset member and the abutment block is the same as the number of positioning blocks and corresponds one-to-one.

[0019] By adopting the above technical solution and setting multiple positioning blocks, the stability of the connection between the clamping seat and the sliding seat is improved, thereby enhancing the reliability of the equipment.

[0020] Preferably, the frame is provided with an abutment groove, one end of the positioning block is slidably embedded in the abutment groove, and the abutment block is located at the bottom of the abutment groove.

[0021] By adopting the above technical solution, the positioning block is slidably embedded in the abutment groove, which guides the sliding of the sliding seat, improves the stability of the sliding of the sliding seat, and improves the reliability of the equipment.

[0022] Preferably, the rotating mechanism includes a placement seat, a gear, a rack, a ratchet, a pawl, and a third reset member. The placement seat is rotatably connected to the frame, and the rotation axis of the placement seat is parallel to the rotation axis of the operating clamp. The upper end of the placement seat is provided with a groove for embedding the workpiece to be processed. The gear is rotatably connected to the frame, and the rotation axis of the gear coincides with the rotation axis of the placement seat. The rack is connected to a sliding seat and meshes with the gear. The ratchet is coaxially connected to the gear. The pawl is connected to the placement seat and is used to embed into the tooth groove on the outer circumference of the ratchet to achieve circumferential fixation between the ratchet and the placement seat. The third reset member is connected between the pawl and the placement seat, and the third reset member makes the pawl tend to embed into the tooth groove on the outer circumference of the ratchet.

[0023] By adopting the above technical solution, the sliding seat slides, which drives the rack to slide. The rack meshes with the gear, which drives the gear to rotate, which in turn drives the ratchet to rotate. The ratchet and pawl cooperate to achieve one-way locking. When the sliding seat slides in a fixed direction, the placement seat can rotate at a certain angle, thereby driving the workpiece to be processed to rotate and achieve the flipping of the workpiece, thus improving the automation level of the equipment.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. The frame can hold the workpiece to be processed, the feeding mechanism can transport the workpiece to be processed to the required process, and the rotating mechanism can rotate the workpiece to be processed by 60°, thereby improving the production efficiency and automation level of the equipment; 2. The second drive cylinder drives the clamping seat to slide, which in turn drives the rotating clamp to slide. The guide column slides within the guide column, driving the two rotating clamps in the same group to move closer or further apart, thereby achieving the clamping and placement of the workpiece to be processed, and improving the production efficiency and automation level of the equipment. 3. The sliding seat slides, driving the rack to slide. The rack meshes with the gear, driving the gear to rotate, which in turn drives the ratchet to rotate. The ratchet and pawl cooperate to achieve one-way locking. When the sliding seat slides in a fixed direction, the placement seat can rotate at a certain angle, thereby driving the workpiece to be processed to rotate and achieve the flipping of the workpiece, thus improving the automation level of the equipment.

[0044] The implementation principle of the production equipment for cold heading ball screw driven actuator nuts in this application embodiment is as follows: the raw material is clamped between two feeding rollers 21. The feeding rollers 21 rotate, driving the raw material to extend into the connecting cavity 12 along the feeding port 13. The cutting drive cylinder 23 drives the cutting blade 22 to slide, realizing the principle of cutting to form a single workpiece to be processed. The workpiece to be processed falls into the dropping port 14 and slides to the connecting groove 15. The piston rod of the first drive cylinder 321 extends out, pushing the drive block 322 to slide. The drive block 322 abuts against the sliding seat 31, pushing the sliding seat 31 to slide, so that the operating clamp 33 extends into the connecting groove 15. The piston rod of the second drive cylinder 35 extends out, pushing the clamping seat 34 to slide, driving the operating clamp 33 to slide. The guide column 332 slides along the guide groove 311, driving the two operating clamps 33 in the same group to approach each other and press against the outer wall of the workpiece to be processed. The piston rod of the first drive cylinder 321 retracts, and the sliding seat 31 slides under the action of the elastic force of the fourth reset member 323, moving the workpiece to be processed out of the connecting groove 15 and facing the first placement seat 41. The piston rod of the second drive cylinder 35 retracts, causing the clamping seat 34 to slide away from the processing cavity 11, and causing the two operating clamps 33 in the same group to move away from each other, so that the workpiece to be processed falls into the groove 411.

[0045] The piston rod of the first drive cylinder 321 extends, pushing the drive block 322 to slide. The drive block 322 abuts against the sliding seat 31, pushing the sliding seat 31 to slide. The rack 43 meshes with the gear 42, driving the gear 42 to rotate, which in turn drives the ratchet 44 to rotate. The piston rod of the second drive cylinder 35 extends, pushing the clamping seat 34 to slide, which in turn drives the operating clamp 33 to slide, simultaneously clamping the workpieces to be processed in the connecting groove 15 and above the first placement seat 41. The piston rod of the first drive cylinder 321 retracts, and the sliding seat 31 slides under the elastic force of the fourth reset member 323. The rack 43 meshes with the gear 42, driving the ratchet 44 to rotate. The pawl 45 is engaged in the tooth groove of the ratchet 44, driving the placement seat 41 to rotate, thus driving the placement seat 41 to rotate 60 degrees, so that the workpieces to be processed can be sequentially transported to each process.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
