[0035] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, like numbers in different figures represent like or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present invention, as detailed in the appended claims.

[0036] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 As shown, the present application provides an extruder, which includes a tool positioning part 1, a tool moving part 2, an extrusion part 3, and an extrusion drive part 4; the tool positioning part 1 is configured to receive the tool 28 to be processed at the material receiving station; the tool moving part 2 is connected to the tool positioning part 1, and the tool moving part 2 is configured to drive the tool positioning part 1 to move from the material receiving station to the extrusion station; the extrusion part 3 is arranged at the extrusion station, and the extrusion station is arranged above the moving path of the tool moving part 2, and the extrusion part 3 is used to radially extrude the copper ring 29 on the tool 28 transported by the tool positioning part 1, and the copper ring 29 is sleeved on the upper end of the pressure needle on the tool and limits the pressure needle up and down; the extrusion drive part 4 is connected to the extrusion part 3, and the extrusion drive part 4 is configured to drive the extrusion part 3 to radially extrude the copper ring.

[0037] like Figure 7As shown, the tooling 28 mentioned in this application includes a pressing needle and a copper ring 29 sleeved on the pressing needle.

[0038] The tooling positioning part 1 is used to connect the materials to the tooling, the tooling moving part 2 is used to move the tooling, the extrusion part 3 and the extrusion drive part 4 are used to radially extrude the copper ring on the tooling, and the cooperation of the tooling positioning part 1, the tooling moving part 2, the extrusion part 3 and the extrusion drive part 4 enables the rapid installation of the pressure pin on the tooling.

[0039] In one implementation, in order to achieve automatic positioning of the tooling, the tooling positioning part 1 includes a support plate 5, a first pushing plate 6, a second pushing plate 7 and a tightening cylinder 8; the support plate 5 is configured to carry the tooling, and the first pushing plate 6 is arranged on the first side of the support plate 5 to limit the first end of the tooling carried by the support plate 5; the second pushing plate 7 is arranged on the second side of the support plate 5 to limit the second end of the tooling carried by the support plate 5; the tightening cylinder 8 is installed on the first side of the support plate 5, and the first pushing plate 6 is connected to the driving end of the tightening cylinder 8, and the tightening cylinder 8 drives the first pushing plate 6 to push the tooling toward the second pushing plate 7 to achieve clamping and positioning of the tooling.

[0040] In one implementation, the first pushing plate 6 and the second pushing plate 7 are U-shaped blocks with openings facing each other and placed horizontally. The tooling is first placed between the first pushing plate 6 and the second pushing plate 7, and then the tightening cylinder 8 pushes the first pushing plate 6 toward the second pushing plate 7, thereby clamping the tooling from both sides. At the same time, the upper edge of the U-shaped block limits the vertical direction of the tooling to prevent the tooling from tilting or moving when being clamped.

[0041] In one implementation, in order to achieve further positioning of the tooling, positioning pits can be set on both sides of the tooling, and a limiting protrusion 9 is set correspondingly on the lower side of the U-shaped block. The positioning pit of the tooling is aligned with the limiting protrusion 9 on the U-shaped block, which can more accurately position the tooling.

[0042] In one implementation, in order to further position the tooling, the tooling positioning portion 1 also includes a card plate 10, which is installed on the support plate 5 and located between the first push plate 6 and the second push plate 7. The card plate 10 is provided with a positioning groove 11 for limiting the tooling.

[0043] The tool positioning groove 11 on the clamping plate 10 is provided to limit the tool perpendicular to the clamping direction, thereby ensuring the accurate position of the tool.

[0044] In one implementation, in order to realize automatic transportation of tooling, the tooling moving part 2 includes a mounting seat 12, a transverse movement device, a sliding plate 13, and a lifting device 14; the mounting seat 12 is used to install the transverse movement device, and the sliding plate 13 is installed on the mounting seat 12 through a slider and rail pair; the transverse movement device is configured to drive the sliding plate 13 to move along the slider and rail pair; the lifting device 14 is installed on the sliding plate 13, and the driving end of the lifting device 14 is connected to the pallet 5, and the lifting device 14 is configured to drive the pallet 5 to rise and fall.

[0045] In one implementation, the transverse movement device includes a motor 15 and a transmission belt 16. The motor 15 is installed on the mounting base 12. The transmission belt 16 is installed on the mounting base 12 through a driving wheel and a roller. The driving end of the motor 15 is connected to the driving wheel of the transmission belt 16. The sliding plate 13 is fixedly connected to the transmission belt 16. The motor 15 drives the sliding plate 13 to move by driving the rotation of the transmission belt 16.

[0046] The lifting device 14 may be a cylinder or a motor 15 . In one embodiment of the present application, a lifting cylinder is used to drive the support plate 5 to move up and down.

[0047] In one implementation, in order to improve the stability of the lifting of the pallet 5, a vertical slide rail 17 is also installed on the sliding plate 13, and a vertical slider that cooperates with the vertical slide rail 17 is installed under the pallet 5. The lifting cylinder drives the pallet 5 to slide along the vertical slide rail 17.

[0048] In one implementation, in order to increase the extrusion efficiency of the extruder, there are multiple extrusion parts 3, which are arranged side by side and spaced apart. The multiple extrusion parts 3 correspond one-to-one to the multiple copper rings 29 on a group of pressing needles on the tooling to be processed.

[0049] by Figure 7 For example, the tooling 28 in the figure has 11 groups of pressing pins arranged in parallel from left to right. Each pressing pin group contains 5 pressing pins, and each pressing pin is provided with a copper ring on its upper end, that is, there are 5 copper rings 29 in a group of pressing pins. Correspondingly, the number of extrusion parts 3 can be set to 5, and the 5 extrusion parts 3 are arranged side by side at intervals, so that the 5 copper rings on a group of pressing pins can be extruded at the same time, thereby improving the extrusion efficiency of the extruder. After a group of copper rings is extruded, the tooling is lowered, moved horizontally, and then raised to extrude the second group of copper rings. In this way, the extrusion of each group of copper rings is completed in sequence.

[0050] In one implementation, to achieve better extrusion of the copper ring, the extrusion unit 3 includes a first extrusion head 18 and a second extrusion head. The first extrusion head 18 is provided with a first protrusion 19, the second extrusion head is provided with a second protrusion 20, the first protrusion 19 is provided with a first extrusion groove 21, and the second protrusion 20 is provided with a second extrusion groove. The driving end of the extrusion drive unit 4 is connected to the first extrusion head 18 and / or the second extrusion head to complete the radial extrusion of the copper ring in the first extrusion groove 21 and the second extrusion groove. Both the first extrusion groove and the second extrusion groove can be configured in a V-shape.

[0051] The setting of the first protrusion 19 and the second protrusion 20 can achieve avoidance with the tooling, effectively avoiding interference between the first extrusion head 18 and the second extrusion head and the tooling frame when extruding the copper ring. At the same time, the setting of the protrusions can also reduce the weight of the first extrusion head 18 and the second extrusion head.

[0052] Correspondingly, such as Figure 5 As shown, in order to increase the extrusion efficiency of the extruder, there are multiple first protrusions 19, which are arranged side by side and spaced apart. The multiple first protrusions 19 correspond one-to-one with the multiple copper rings 29 on a group of press pins on the tooling to be processed. The second protrusions 20 correspond one-to-one with the first protrusions 19.

[0053] In one implementation, the extrusion drive unit 4 can be a cylinder, a motor 15, or a gas-liquid booster cylinder. The extrusion drive unit 4 can be connected only to the first extrusion head 18, with the second extrusion head fixed. The extrusion drive unit 4 drives all the first extrusion heads 18 to move toward the corresponding second extrusion heads to achieve the extrusion of the copper ring. Similarly, the extrusion drive unit 4 can also be connected only to the second extrusion head. Of course, the extrusion drive unit 4 can be connected to the first extrusion head 18 and the second extrusion head at the same time, driving the first extrusion head 18 and the second extrusion head to extrude or release the copper ring.

[0054] In one implementation, Figure 6 As shown, in order to increase the accuracy of extrusion of the extrusion part 3 and improve the extrusion quality, the extruder also includes a copper ring regularization part 22; the copper ring regularization part 22 is arranged between the material receiving station and the extrusion station, and the copper ring regularization part 22 is configured to regularize the copper rings to be extruded on the tooling.

[0055] In one implementation, the copper ring regularization portion 22 includes a copper ring regularization plate 23 , and the copper ring regularization plate 23 is provided with a copper ring regularization groove 24 opening downward.

[0056] The tooling 28 moves to the bottom of the copper ring regularization plate 23, and the tooling moving part 2 drives the tooling 28 to rise, so that the copper rings on the tooling enter the copper ring regularization groove 24 for regularization. In order to achieve the simultaneous regularization of a group of copper rings, the number of copper ring regularization grooves 24 can be set to multiple, and correspond one-to-one to the multiple copper rings 29 on a group of pressure needles on the tooling to be processed.

[0057] In one implementation, the copper ring regularization groove 24 can be an elongated strip-shaped through groove, and the extension direction of the strip-shaped through groove is perpendicular to the arrangement direction of multiple copper rings on a group of pressure needles, so that the copper ring regularization groove 24 can regularize the copper rings on multiple groups of pressure needles at the same time.

[0058] In one implementation, in order to avoid damage to the tooling and the copper ring, the copper ring regularization part 22 also includes a main connecting plate 25 and a secondary connecting plate 26; the copper ring regularization plate 23 is installed on the secondary connecting plate 26, and the secondary connecting plate 26 is slidably installed on the main connecting plate 25; the copper ring regularization part 22 also includes a guide shaft and a spring 27, the first end of the guide shaft is fixed on the main connecting plate 25, and the second end of the guide shaft is fixed on the secondary connecting plate 26, and the spring 27 is sleeved on the guide shaft and located between the main connecting plate 25 and the secondary connecting plate 26.

[0059] The tooling rises and the copper ring is pushed into the copper ring regularization groove 24 for regularization. Under the lifting force applied by the tooling and the downward pressure applied by the spring 27, the copper ring regularization plate 23 performs dynamic elastic regularization on the copper ring to avoid rigid regularization damaging the tooling and the copper ring.

[0060] In one implementation, the extruded bottom surface of the extruded portion 3 and the regularized bottom surface of the regularized portion have the same height.

[0061] By setting the extrusion bottom surface of the extrusion part 3 and the regularization bottom surface of the regularization part at the same height, the copper rings on the tooling can be radially extruded while the remaining copper rings to be processed on the tooling can be regularized.

[0062] In one implementation, the action flow of the extruder is as follows: first, the tooling is placed on the tooling positioning part 1 to connect the tooling, and then the tightening cylinder 8 is used to drive the first push plate 6 to clamp the tooling in place; then the tooling moving part 2 is used to move the tooling to the copper ring regularization part 22. After moving to the bottom of the copper ring regularization part 22, the tooling moving part 2 drives the tooling to rise, and several groups of copper rings located at the front of the tooling enter the copper ring regularization part 22 for regularization. After the copper ring regularization is completed, the tooling moving part 2 drives the tooling to descend and move forward, and then It rises to the extrusion station, and the extrusion part 3 radially extrude the first group of copper rings that have been regularized. At the same time, several groups of copper rings located at the rear of the tooling enter the copper ring regularization part 22 for regularization. After the radial extrusion of the first group of copper rings is completed, the tooling moving part 2 drives the tooling to descend and move forward, and then rises to the extrusion station, and the extrusion part 3 radially extrude the second group of copper rings that have been regularized. At the same time, the regularization part 22 can still regularize several groups of copper rings located at the rear of the tooling, and so on. The cycle continues until the radial extrusion of all copper rings on the tooling is completed.

[0063] To sum up, the extruder provided in the present application realizes the material connection of the tooling through the setting of the tooling positioning part 1, realizes the movement of the tooling through the setting of the tooling moving part 2, realizes the radial extrusion processing of the copper ring on the tooling through the extrusion part 3 and the extrusion drive part 4, and realizes the rapid extrusion of the copper ring on the tooling through the cooperation of the tooling positioning part 1, the tooling moving part 2, the extrusion part 3, and the extrusion drive part 4, thereby realizing the rapid installation of the pressing needle, with stable and reliable quality and labor saving.
