Description

Technical Field

[0001] The present invention relates to the technical field of straightening, and particularly relates to a straightening device for copper rod processing. Background Art

[0002] A copper rod is a kind of non-ferrous metal processing rod. Copper rod straightening is an operation process of restoring a bent copper rod to a straight state through certain processes and equipment.

[0003] In related technologies, the straightening methods include mechanical straightening and stretching straightening. Among them, mechanical straightening is to repeatedly roll-press the copper rod with straightening rollers to gradually eliminate the bending deformation. Stretching straightening is to apply an axial tensile force to the copper rod through stretching equipment, so that the copper rod undergoes plastic deformation under the action of the tensile force, thereby achieving the purpose of straightening.

[0004] The Chinese patent document with the authorization announcement number CN104399783B discloses a stretching straightening machine and a stretching straightening method. The stretching straightening machine includes a main stretching device and a secondary stretching device. The main stretching device includes a main machine base and a guide rail support slide seat arranged on the main machine base. A main stretching chuck that slides with a single degree of freedom and a stretching oil cylinder for driving the main stretching chuck to slide are arranged on the guide rail support slide seat. A sliding rail that cooperates with each other is arranged between the guide rail support slide seat and the main stretching chuck. The secondary stretching device includes a secondary machine base. A secondary stretching chuck for clamping the profile is installed on the secondary machine base. First jaws and second jaws for fixing the profile are respectively correspondingly arranged on the opposite side surfaces of the main stretching chuck and the secondary stretching chuck. The main stretching chuck further includes a straightening channel, and the straightening channel includes a straightening chuck opening.

[0005] Before straightening, the above patent clamps and fixes one end of the profile through the second jaws, adjusts the size of the straightening chuck opening to be suitable for the diameter of the profile, starts the stretching oil cylinder to move the main stretching chuck, and pre-straightens the profile. When one end of the profile arranged on the profile support frame moves into the straightening channel, adjusts the size of the first jaws to fix the profile, and then continues to move the main stretching chuck to perform stretching straightening on the profile.

[0006] However, when straightening a longer rod, the stroke of the main stretching device in the above patent is required, which requires increasing the overall floor area of the equipment. Therefore, it is not suitable for workshops where the equipment is relatively compact. Therefore, it is necessary to design a new straightening device that can be suitable for straightening longer rods. Summary of the Invention

[0007] The present invention provides a straightening device for copper rod processing, aiming to solve the problem that it is difficult to straighten longer rods in related technologies.

[0008] The straightening device for copper rod processing of the present invention includes: a frame body, a die system, and a clamping system;

[0009] The mold system is provided on the frame body;

[0010] The clamping system includes a first clamping assembly and a second clamping assembly, and both the first clamping assembly and the second clamping assembly are slidably engaged with the frame body;

[0011] The first clamping assembly includes a first sliding seat, a first clamping block, a second clamping block, a first locking mechanism and a reset plate. The first sliding seat is slidably engaged with the frame body. The first clamping block and the second clamping block are slidably engaged within the sliding seat. The reset plate is slidably engaged within the first sliding seat. The reset plate is connected to the first sliding seat through a first elastic member. The reset plate can push the first clamping block and the second clamping block to extend out of the first sliding seat. The locking mechanism is provided between the first clamping block and the second clamping block and is used to drive the two to approach or move away from each other. The second clamping assembly includes a second sliding seat, a third clamping block, a fourth clamping block and a second locking mechanism. The second sliding seat is slidably engaged with the frame body. The third clamping block and the fourth clamping block are slidably engaged within the second sliding seat. The second locking mechanism is provided between the third clamping block and the fourth clamping block and is used to control the two to approach or move away from each other.

[0012] Beneficial effects: One end of the workpiece extends out of the mold system. The first sliding seat and the second sliding seat reciprocate towards or away from each other during the straightening process. Thus, when they approach each other, the first locking mechanism controls the first clamping block and the second clamping block to clamp the workpiece, and the first clamping mechanism pulls the workpiece through the mold system to perform the straightening operation. At this time, the first clamping block and the second clamping block extend out of the first sliding seat. When the first clamping block and the second clamping block abut against the third clamping block and the fourth clamping block, the first locking mechanism controls the first clamping block and the second clamping block to release the workpiece. Subsequently, the third clamping block and the fourth clamping block push the first clamping block and the second clamping block into the first sliding seat until the third clamping block and the fourth clamping block move to the original positions of the first clamping block and the second clamping block. At this time, the second locking mechanism drives the third clamping block and the fourth clamping block to lock the workpiece, so as to ensure that the clamping position remains unchanged and prevent the workpiece from being unevenly stressed during the alternation of the first clamping assembly and the second clamping assembly. Subsequently, the first sliding seat and the second sliding seat move away from each other, and the second clamping mechanism pulls the workpiece to perform the straightening operation, thereby realizing continuous straightening of the copper rod without interruption.

[0013] Preferably, the first locking mechanism includes a first driving member, a first locking plate, a first slider, and a second slider. The first driving member is provided on the first sliding seat. The first locking plate is connected to the output end of the first driving member. First chutes are provided at the tops of the first clamping block and the second clamping block. The first slider and the second slider are respectively slidably engaged in the corresponding first chutes. Two first fitting holes are provided on the first locking plate at intervals. The first slider and the second slider are respectively slidably engaged in the corresponding first fitting holes. Two first inclined chutes are provided on the first sliding seat in opposite directions. The first slider and the second slider are respectively slidably engaged with the corresponding first inclined chutes.

[0014] The effect is that by driving the first locking plate to move by the first driving member, it is possible to drive the first slider and the second slider to move along the first inclined chute, thereby realizing pushing the first clamping block and the second clamping block to approach or move away from each other. And when the first clamping block and the second clamping block are retracted into or extended out of the first sliding seat, the first slider and the second slider slide in the corresponding first chutes, preventing the first slider and the second slider from affecting the retraction or extension of the first clamping block and the second clamping block into or out of the first sliding seat.

[0015] Preferably, the second locking mechanism includes a second driving member, a second locking plate, a third slider, and a fourth slider. The second driving member is provided on the second sliding seat. The second locking plate is connected to the output end of the second driving member. Two second inclined chutes are provided at the tops of the third clamping block and the fourth clamping block in opposite directions. The third slider and the fourth slider are spaced apart on the second locking plate. The third slider and the fourth slider are both slidably engaged in the corresponding second inclined chutes.

[0016] Preferably, a limiting mechanism is further provided in the first sliding seat. The limiting mechanism is used to prevent the first clamping block and the second clamping block from rebounding.

[0017] The effect is that the limiting plate can fix the first clamping block and the second clamping block, preventing the first clamping block and the second clamping block from moving during the process of clamping the workpiece and affecting the straightening quality.

[0018] Preferably, the limiting mechanism includes a limiting plate and a second elastic member. The limiting plate is located between the first clamping block and the second clamping block and the bottom surface of the first sliding seat. The bottom end of the limiting plate is connected to the bottom surface of the first sliding seat through the second elastic member. One-way tooth grooves are provided on the limiting plate. One-way teeth are provided on the bottom surfaces of the first clamping block and the second clamping block. The one-way teeth can be engaged with the one-way tooth grooves. The limiting plate can limit the first clamping block and the second clamping block unidirectionally.

[0019] The effect is that during the process of the first clamping block and the second clamping block clamping the workpiece, due to the extrusion of the workpiece by the die system, the workpiece exerts a pulling force towards the die on the first clamping block and the second clamping block. Therefore, only one-way limiting of the first clamping block and the second clamping block is required to fix the first clamping block and the second clamping block.

[0020] Preferably, the first sliding seat can extend out of the reset plate, and the upper surface of the reset plate can abut against the workpiece, so as to be able to lift the workpiece.

[0021] The effect is that the reset plate can lift the workpiece, thereby preventing the workpiece from bending under its own gravity.

[0022] Preferably, the die system includes a fixed seat and a straightening plate. The fixed seat is fixedly connected to the frame body, the straightening plate is fixedly connected to the fixed seat, and the straightening plate is provided with a straightening hole.

[0023] Preferably, a guide rail is provided on the frame body. Both the first sliding seat and the second sliding seat are slidably matched with the guide rail, and both the first sliding seat and the second sliding seat can slide along the guide rail.

[0024] Preferably, a pre-straightening system is provided on the frame body, and the straightening system is used for pre-straightening the copper rod.

[0025] The effect is that pre-straightening the workpiece can first straighten the workpiece with a larger bending degree into a column with a smaller bending degree, thus facilitating subsequent straightening treatment.

[0026] Preferably, the pre-straightening system includes a transverse straightening system and a longitudinal straightening system. The transverse straightening system includes a first straightening plate and a plurality of first straightening wheels. The first straightening plate is horizontally arranged on the frame body, and the plurality of first straightening wheels are spaced apart on the first straightening plate and are all rotatably matched with the first straightening plate. The longitudinal straightening system includes a second straightening plate and a plurality of second straightening wheels. The second straightening plate is vertically arranged on the frame body, and the plurality of second straightening wheels are spaced apart on the second straightening plate and are all rotatably matched with the second straightening plate.

[0027] Adopting the above technical solutions, the beneficial effects of the present invention are as follows:

[0028] According to the straightening device for copper rod processing of the present invention, one end of the workpiece extends out of the mold system. The first sliding seat and the second sliding seat reciprocate towards or away from each other during the straightening process. Thus, when they approach each other, the first locking mechanism controls the first clamping block and the second clamping block to clamp the workpiece, and the first clamping mechanism pulls the workpiece through the mold system to perform the straightening operation. At this time, the first clamping block and the second clamping block extend out of the first sliding seat. When the first clamping block and the second clamping block abut against the third clamping block and the fourth clamping block, the first locking mechanism controls the first clamping block and the second clamping block to release the workpiece. Subsequently, the third clamping block and the fourth clamping block push the first clamping block and the second clamping block into the first sliding seat until the third clamping block and the fourth clamping block move to the original positions of the first clamping block and the second clamping block. At this time, the second locking mechanism drives the third clamping block and the fourth clamping block to lock the workpiece, so as to ensure that the clamping position remains unchanged and prevent the workpiece from being unevenly stressed during the alternation of the first clamping assembly and the second clamping assembly. Subsequently, the first sliding seat and the second sliding seat move away from each other, and the second clamping mechanism pulls the workpiece to perform the straightening operation, thereby realizing continuous straightening of the copper rod without interruption.

The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0040] As Figures 1 to 8 shown, the straightening device for copper rod processing of the present invention includes: a frame 1, a die system, and a clamping system.

[0043] As Figures 1 to 6As shown in the figure, the clamping system includes a first clamping assembly 31 and a second clamping assembly 32. The first clamping assembly 31 includes a first sliding seat 311, a first clamping block 312, a second clamping block 313, a first locking mechanism 314 and a reset plate 315. The inside of the first sliding seat 311 is a hollow structure. There is a first circular hole at its right end and a first opening at its left end. The workpiece can extend into the first sliding seat 311 from the first circular hole. Guide grooves are provided at both the front end and the rear end of the first sliding seat 311. The guide grooves are slidably matched with the guide rails 104. Two limit posts 6 are provided at the bottom end of the first sliding seat 311. The annular outer edge 103 on the left driving seat 102 can extend between the two limit posts 6. When the driving seat 102 rotates, the first sliding seat 311 is driven to move left and right along the guide rail 104 through the annular outer edge 103. The first clamping block 312 and the second clamping block 313 are slidably matched inside the first sliding seat 311. The clamping centers of the first clamping block 312 and the second clamping block 313 are coaxially distributed with the center of the straightening hole. The first clamping block 312 and the second clamping block 313 can move left and right and back and forth inside the first sliding seat 311. The first locking mechanism 314 includes a first driving member 3141, a first locking plate 3142, a first slider 3143 and a second slider 3144. The first driving member 3141 is fixedly arranged at the top end of the first sliding seat 311. The first driving member 3141 is a hydraulic cylinder. The first locking plate 3142 is fixedly connected to the output end of the first driving member 3141. First sliding grooves 3145 are provided on both the first clamping block 312 and the second clamping block 313. The first slider 3143 is slidably matched in the first sliding groove 3145 on the first clamping block 312. The second slider 3144 is slidably matched in the first sliding groove 3145 on the second clamping block 313. Two spaced-apart first mating holes are provided on the first locking plate 3142. The first slider 3143 and the second slider 3144 respectively pass through the corresponding first mating holes, and the first slider 3143 and the second slider 3144 are respectively slidably matched with the corresponding first mating holes. The first slider 3143 and the second slider 3144 can move back and forth relative to the first locking plate 3142. Two oppositely distributed first inclined grooves 3146 are provided on the top surface of the first sliding seat 311. The tops of the first slider 3143 and the second slider 3144 are respectively slidably matched in the corresponding first inclined grooves 3146. The reset plate 315 is slidably matched inside the first sliding seat 311, and the reset plate 315 is elastically connected to the left side wall of the first sliding seat 311 through a first elastic member 316. The first elastic member 316 is a spring. The right end of the reset plate 315 can abut against the first clamping block 312 and the second clamping block 313. The left end of the reset plate 315 can extend out of the first sliding seat 311. The reset plate 315 can abut against the workpiece on the left side of the first sliding seat 311, so as to be able to lift the workpiece.

[0044] When the first driving member 3141 drives the first locking plate 3142 to move rightward, the first locking plate 3142 drives the first slider 3143 and the second slider 3144 to move rightward. The first slider 3143 and the second slider 3144 move rightward along the corresponding first inclined slots 3146 and gradually approach each other, thereby pushing the first clamping block 312 and the second clamping block 313 to approach each other. When the first driving member 3141 drives the first locking plate 3142 to move leftward, similarly, the first clamping block 312 and the second clamping block 313 move away from each other.

[0045] As Figure 5 shown, a limiting plate 41 is further provided in the first sliding seat 311. The limiting plate 41 is located between the first clamping block 312 and the second clamping block 313 and the bottom surface of the first sliding seat 311. The bottom end of the limiting plate 41 is elastically connected to the bottom end of the first sliding seat 311 through a second elastic member 42. A one-way tooth groove is provided at the top end of the limiting plate 41, and one-way teeth are provided at the bottom ends of the first clamping block 312 and the second clamping block 313. The one-way teeth can be engaged with the one-way tooth groove.

[0046] As Figure 4 、 Figure 5 、 Figure 7 and Figure 8As shown in the figure, the second clamping assembly 32 includes a second sliding seat 321, a third clamping block 322, a fourth clamping block 323 and a second locking mechanism. The structure of the second sliding seat 321 is the same as that of the first sliding seat 311. A second circular hole is provided at the right end thereof, and the workpiece can extend out of the second sliding seat 321 through the second circular hole. A second opening is provided at the left end of the second sliding seat 321. Guide grooves are provided on the front and rear sides of the second sliding seat 321, and the guide grooves are slidably engaged with the guide rails 104. Two spaced-apart limit posts 6 are provided at the bottom of the second sliding seat 321. The annular outer edge 103 on the right driving seat 102 extends between the two limit posts 6. When the driving seat 102 rotates, the second sliding seat 321 is driven to move left and right along the guide rails 104 through the annular outer edge 103, so that the first sliding seat 311 and the second sliding seat 321 move towards or away from each other. The third clamping block 322 and the fourth clamping block 323 are slidably engaged within the second sliding seat 321, and they can approach or separate from each other. The clamping centers of the third clamping block 322 and the fourth clamping block 323 are coaxially distributed with the center of the straightening hole. The second locking mechanism includes a second driving member 3241, a second locking plate 3242, a third slider 3243 and a fourth slider 3244. The second driving member 3241 is fixedly provided at the top of the second sliding seat 321. The second driving member 3241 is a hydraulic cylinder. The second locking plate 3242 is fixedly connected to the output end of the second driving member 3241. Both the third slider 3243 and the fourth slider 3244 are fixedly connected to the bottom end of the second locking plate 3242 and are spaced apart from each other. Second inclined grooves 3245 are provided on the top surfaces of the third clamping block 322 and the fourth clamping block 323, and the two second inclined grooves 3245 are distributed oppositely. The third slider 3243 is slidably engaged in the second inclined groove 3245 on the third clamping block 322, and the fourth slider 3244 is slidably engaged in the second inclined groove 3245 on the fourth clamping block 323. A pressure rod is further provided on the second sliding seat 321, and the left end of the pressure rod extends outwards through the second opening. When the first sliding seat 311 and the second sliding seat 321 approach and abut against each other, the pressure rod can abut against the top end of the limiting plate 41 and push the limiting plate 41 to move downwards, and the second elastic member 42 is compressed, so that the limiting plate 41 is disengaged from contact with the first clamping block 312 and the second clamping block 313.

[0047] When the second driving member 3241 drives the second locking plate 3242 to move leftwards, the second locking plate 3242 drives the third slider 3243 and the fourth slider 3244 to move leftwards along the corresponding second inclined grooves 3245, so that the third slider 3243 and the fourth slider 3244 approach each other, and further push the third clamping block 322 and the fourth clamping block 323 to approach each other. Similarly, when the second driving member 3241 drives the second locking plate 3242 to move rightwards, the third clamping block 322 and the fourth clamping block 323 separate from each other.

[0048] As Figure 1 and Figure 2As shown in the figure, a straightening system is also provided on the left side of the frame body 1. The straightening system includes a horizontal straightening system and a vertical straightening system. The horizontal straightening system includes a first straightening plate 511 and a plurality of first straightening wheels 512. The first straightening plate 511 is horizontally arranged and fixedly connected to the frame body 1. The plurality of first straightening wheels 512 are spaced apart on the first straightening plate 511, and each first straightening wheel 512 is rotatably connected to the first straightening plate 511. The vertical straightening system includes a second straightening plate 521 and a plurality of second straightening wheels 522. The second straightening plate 521 is vertically arranged, and its bottom end is fixedly connected to the frame body 1. The plurality of second straightening wheels 522 are spaced apart on the second straightening plate 521, and each second straightening wheel 522 is rotatably connected to the second straightening plate 521.

[0049] The implementation principle of the straightening device for copper rod processing in the embodiment of the present invention is as follows: The workpiece gradually moves from the left end of the frame body 1 to the right. The workpiece first passes through the first straightening wheel 512 and the second straightening wheel 522. The first straightening wheel 512 and the second straightening wheel 522 can squeeze the bent part of the workpiece to pre-straighten the workpiece, thereby reducing the bending degree of the workpiece. The straightened workpiece passes through the straightening hole and extends into the straightening groove. At this time, the first clamping assembly 31 and the second clamping assembly 32 are respectively located on the left and right sides of the straightening groove, and at this time, the right ends of the first clamping block 312 and the second clamping block 313 both extend outward. The second elastic member 42 exerts an upward thrust on the limiting plate 41, so that the limiting plate 41 meshes with the first clamping block 312 and the second clamping block 313, thereby restricting the first clamping block 312 and the second clamping block 313 from moving to the left. When the workpiece extends into the first sliding seat 311, the first locking mechanism 314 drives the first clamping block 312 and the second clamping block 313 to approach each other, so as to clamp the workpiece. Subsequently, the driving motor drives the main shaft 101 to rotate, and the first sliding seat 311 and the second sliding seat 321 move towards each other and approach each other. During this process, since the first clamping block 312 and the second clamping block 313 tightly clamp the workpiece, the workpiece is pulled to move to the right. Since the clamping centers of the first clamping block 312 and the second clamping block 313 are coaxially distributed with the center of the straightening hole, the part of the workpiece extending out of the straightening hole can be kept straight while pulling the workpiece. At the same time, under the action of the first elastic member 316, the reset plate 315 gradually extends and moves to the left and the first sliding seat 311. The left end of the reset plate 315 always abuts against the left end of the straightening groove. The reset plate 315 always supports the workpiece on the left side of the first sliding seat 311, thereby preventing the workpiece from bending under its own gravity. After the reset plate 315 moves to the left, it disengages from contact with the first clamping block 312 and the second clamping block 313.

[0050] When the pressing plate 43 abuts against the limiting plate 41, the pressing plate 43 presses the limiting plate 41, causing the second elastic member 42 to be compressed. The limiting plate 41 is disengaged from the first clamping block 312 and the second clamping block 313, and the limiting of the first clamping block 312 and the second clamping block 313 by the limiting plate 41 is released. Subsequently, the third clamping block 322 and the fourth clamping block 323 abut against the first clamping block 312 and the second clamping block 313. At the same time, the first locking mechanism 314 drives the first clamping block 312 and the second clamping block 313 to loosen the workpiece. The third clamping block 322 and the fourth clamping block 323 push the first clamping block 312 and the second clamping block 313 into the first sliding seat 311. At this time, the third clamping block 322 and the fourth clamping block 323 are located at the positions of the original first clamping block 312 and the second clamping block 313. The second locking mechanism drives the third clamping block 322 and the fourth clamping block 323 to clamp the workpiece, so as to ensure that the clamping position remains unchanged. Subsequently, the first sliding seat 311 and the second sliding seat 321 move away from each other. During this process, the second sliding seat 321 moves to the right and pulls the workpiece, so that the workpiece continues the straightening operation. The first sliding seat 311 moves to the left. After the pressing plate 43 is separated from the limiting plate 41, the limiting plate 41 moves upward under the action of the second elastic member 42 and meshes with the first clamping block 312 and the second clamping block 313. The reset plate 315 is gradually received into the first sliding seat 311 and pushes the first clamping block 312 and the second clamping block 313 to move relative to the first sliding seat 311 to the right and extend out of the first sliding seat 311. When the first sliding seat 311 moves to the left end of the straightening groove and the second sliding seat 321 moves to the right end of the straightening groove, the first locking mechanism 314 drives the first clamping block 312 and the second clamping block 313 to clamp the workpiece, and the second locking mechanism drives the third clamping block 322 and the fourth clamping block 323 to loosen the workpiece. Then, the above process is repeated until the workpiece completes the straightening operation.
