Detailed Description
The following description of the embodiments of the present utility model will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to fall within the scope of the utility model.
As shown in fig. 1, 2, 3, 4 and 6, a copper needle board trimming machine comprises a base, a clamp table 1 arranged on the base and a feeding trimming structure for trimming copper pins on the copper needle board;
The fixture table 1 is provided with workpiece holes 1a, a porous screen plate 101 is fixed in the workpiece holes 1a, meshes 101a of the porous screen plate 101 correspond to copper pins one by one, and the copper pins are matched with the corresponding meshes 101 a;
The feeding trimming structure comprises a transverse trimming blade 201 capable of moving back and forth, and the height of the highest point of the transverse trimming blade 201 is lower than that of the lowest point of the workpiece hole 1 a;
The fixture is characterized in that a lifter 3 is arranged above the fixture table 1, a workpiece pressing block 301 for pressing the back surface of the copper needle plate is arranged on the lifter 3, the vertical projection of any copper needle is in the vertical projection range of the workpiece pressing block 301, and a waste bin 4 is arranged below the fixture table 1 by the workpiece pressing block 301.
In the prior art, one of the two plate surfaces of the copper needle plate, which is provided with copper pins, is a front surface, and the other surface is a back surface.
When the copper needle plate after cold forging is needed to be trimmed, the copper needle plate is placed into the workpiece hole 1a on the fixture table 1 in a front downward mode, copper pins penetrate through corresponding meshes 101a (the aperture of the meshes 101a is consistent with the outer diameter of the copper pins, the copper pins are extruded into the meshes 101a, so that the copper pins and the meshes 101a can relatively move up and down, but a certain external force needs to be applied), the meshes 101a can assist in fixing and limiting the copper pins, and the lower ends of the copper pins extend out to the lower side of the fixture table 1 after the copper needle plate is placed in place.
In practice, copper plates of copper needle plates produced by cold forging are not perfectly flat (copper plates have a limited thickness and copper itself is "soft", which is equivalent to a metal plate that is not leveled, with some bending). In view of this, after the copper needle plate is put in place, the lifter 3 is lowered to press the workpiece pressing block 301 against the back surface of the copper needle plate, and since "the vertical projection of any copper stitch falls within the vertical projection range of the workpiece pressing block 301", it can be ensured that the upper ends of the copper stitches are just flush with the upper ends of the mesh 101a, that is, that the middle portion of the front surface of the copper plate is stuck on the upper surface of the porous screen plate 101 (the "middle portion of the front surface of the copper plate" referred to herein covers all the upper ends of the copper stitches). And then, transversely moving the transverse trimming blade 201 to feed, trimming all copper pins, transversely moving the transverse trimming blade 201 to retract, and taking away the copper needle plate by a worker. During the transverse cutting feeding process of the transverse trimming blade 201, the trimmed copper stitch lower section waste falls into the waste bin 4.
As shown in fig. 1, 2, 4 and 6, the fixture table 1 is provided with a large workpiece groove 1b, the large workpiece groove 1b is opened on the top surface of the fixture table 1, the lower end of the workpiece hole 1a is opened on the bottom surface of the fixture table 1, the upper end of the workpiece hole 1a is opened on the bottom surface of the large workpiece groove 1b, at least one pair of protection rubber mats 5 are arranged in the large workpiece groove 1b, and one pair of protection rubber mats 5 are arranged in the protection rubber mats 5: the protection rubber pad 5 includes a contact protection portion 501 for contacting the front edge of the copper needle plate and a fixing protection portion 502 fixed with the large workpiece groove 1 b.
As described in the background art, the edge portion of the copper needle board just produced is quite irregular, so that the edge portion of the copper needle board may scratch the fixture table 1, in this embodiment, at least one pair of protection rubber pads 5 is provided to pad the edge of the copper needle board, so that the edge of the copper needle board is "lifted", and the middle portion of the back of the copper needle board is pressed by the workpiece pressing block 301, or the middle portion of the front of the copper board is guaranteed to be attached to the upper surface of the porous screen 101 (as described above, the "middle portion of the front of the copper board" referred to herein covers all the upper ends of copper pins). In addition, after trimming is completed, a worker is required to manually take away the copper needle plate, originally, the worker needs to separate the copper plate of the copper needle plate from the fixture table 1 (to scratch the edge of the copper plate) by fingers, and then pull the copper plate upwards to take away the copper needle plate, and after the protective rubber cushion 5 is arranged, the worker is relatively easier to scratch the edge of the copper needle plate from the elastic protective rubber cushion 5. This is because both the copper plate and the jig table 1 are hard, while the protective rubber pad 5 is elastic and soft, and the fingers are squeezed between two hard things to perform the picking action, and naturally no fingers are squeezed between one hard thing and one soft thing to perform the picking action (the soft things can deform, and more space can be naturally reserved for the fingers, so that the picking action is facilitated).
As shown in fig. 2, 3 and 8, the feeding trimming structure further includes a driving mechanism for driving the transverse trimming blade 201 to reciprocate, the transverse trimming blade 201 is connected with the driving mechanism through two trimming blade connecting rods 202, the feeding trimming structure further includes a polishing roller 203 and a polishing motor for driving the polishing roller 203 to rotate, and the polishing roller 203 is located between the two trimming blade connecting rods 202, before trimming copper pins: the transverse trimming 201 is located between the grinding roller 203 and either copper stitch.
In the process of trimming copper pins by the transverse trimming blade 201, after trimming a row of copper pins by the front transverse trimming blade 201, the trimmed copper pins are polished by the polishing roller 203 at the rear, so that the problem that the lower ends of the copper pins are too sharp can be solved.
The driving mechanism is an electric cylinder or an electric sliding block or an oil cylinder or an electric push rod or an air cylinder.
The drive mechanism may be any conventional mechanism that can be reciprocally driven and moved.
As shown in fig. 2, 5 and 7, two symmetrically arranged auxiliary through holes 1c are provided on the fixture table 1, any copper pin is located between the two auxiliary through holes 1c, two piece discharging devices 6 corresponding to the auxiliary through holes 1c one by one are provided in the waste bin 4, and in the corresponding auxiliary through holes 1c and piece discharging devices 6: the piece outlet device 6 comprises a piece outlet head 601 which can pass through the auxiliary through hole 1c and a piece outlet cylinder 602 for driving the piece outlet head 601 to move up and down, wherein the piece outlet head 601 comprises a roller frame 601.1 driven by the piece outlet cylinder 602 and a transverse roller 601.2 rotationally connected with the roller frame 601.1, and the highest point of the transverse roller 601.2, the highest point of the roller frame 601.1 and the lowest point of the transverse roller 601.2 are sequentially arranged from top to bottom.
After trimming, the piece outlet cylinder 602 drives the piece outlet head 601 to pass through the auxiliary through hole 1c, so that both sides of the front side of the copper plate of the copper needle plate are jacked up, and therefore, a worker does not need to use fingers to pick up the copper plate, but directly grabs the copper plate to be jacked up, and pulls the copper plate upwards, and the whole copper needle plate is taken out. In addition, the cross roller 601.2 is provided in the stripper 6 as a contact member, so that the copper pin lower section scraps falling during the previous trimming cannot stay on the cross roller 601.2, and the contact member (the cross roller 601.2) can be ensured to smoothly contact with the copper plate of the copper needle plate.
The foregoing has outlined rather broadly the more detailed description of embodiments of the utility model, wherein the principles and embodiments of the utility model are explained in detail using specific examples, the above examples being provided solely to facilitate the understanding of the method and core concepts of the utility model; meanwhile, as those skilled in the art will have variations in the specific embodiments and application scope in light of the ideas of the present utility model, the present description should not be construed as limiting the present utility model.
