Description

Technical Field

[0001] This utility model relates to the field of cold heading mold technology, and in particular to an in-mold cutting forming mechanism for cold heading of pole plate caps. Background Technology

[0002] The processing technology for the battery terminal cover plate is as shown in the instruction manual. Figure 1 and Figure 2 As shown, the process includes a sheet metal 10 and a finished product 20. The process consists of four steps: cutting the square profile on a saw, shot blasting, cold extrusion by a hydraulic press, and edge trimming by a punch. After selecting the sheet metal, the sheet metal 10 is placed on a saw and its shape is cut to obtain the finished product 20. Then, the burrs of the finished product 20 are removed by shot blasting. The finished product 20 is then extruded and shaped by a hydraulic press. Finally, the finished product 20 is edge trimmed by a punch to obtain the finished product.

[0003] In the cutting process, the workpiece is usually cut from the inside of the sheet material by mold closing and stamping. The existing die-cutting mechanism is not convenient for cutting the workpiece during the cutting process, and it needs to be manually collected after the cutting is completed, so the forming efficiency is low.

[0004] Based on this, in order to further optimize the processing efficiency of existing die-cutting mechanisms, we propose an in-die cutting forming mechanism for cold heading of pole plate. Utility Model Content

[0005] The purpose of this invention is to solve the shortcomings of existing technologies, such as inconvenience in feeding processed products, the need for manual collection after cutting, and low forming efficiency, and to propose an in-mold cutting forming mechanism for cold heading of pole plate.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design an in-mold cutting forming mechanism for cold heading of pole plate, including:

[0008] The lower mold base and the lower mold assembly mounted on the lower mold base;

[0009] A plurality of guide pillars are fixedly installed at the upper end of the lower mold base, and an upper mold base is slidably connected between the plurality of guide pillars. An upper mold is installed at the lower end of the upper mold base.

[0010] The lower die assembly includes a mounting bracket and a lower die. The lower die has a plurality of forming holes on its end face, and the bottom of the upper die has a punch that matches the forming holes.

[0011] The upper side of the mounting bracket has a lifting assembly that inserts into the lower mold.

[0012] Furthermore, the mounting bracket is fixed to the upper end of the lower mold base, and a clearance opening is provided at the upper end of the mounting bracket to avoid the forming hole.

[0013] Furthermore, the lifting assembly includes a sleeve fixedly mounted on the mounting bracket, a push rod movably inserted into the inner side of the sleeve, and a spring fixedly connected between the bottom of the push rod and the sleeve;

[0014] The top end of the push rod extends to the upper side of the lower mold.

[0015] Furthermore, air holes are provided at the bottom of several of the punches, and an air passage structure is provided inside the upper die.

[0016] Furthermore, the air passage structure includes an air channel formed in the upper mold, one end of which extends through to the outside of the upper mold and is connected to a connector;

[0017] The airway is connected by several branch air passages and several air holes.

[0018] Furthermore, the lower mold base has a feed port in the middle;

[0019] The upper mold base and the upper mold are detachably connected; the mounting bracket and the lower mold are detachably connected.

[0020] The present invention proposes an in-mold cutting forming mechanism for cold heading of pole post cover plates. The advantages are as follows: In this invention, a punch at the bottom of the upper mold is pressed into the forming hole to complete the stamping and cutting of the processed material inside the sheet metal. The design of multiple punches and forming holes allows for the simultaneous forming of multiple pole post cover plates. The processed material automatically falls downwards for easy collection. Furthermore, a lifting component is provided in the lower mold to lift the entire sheet metal. During mold closing and cutting, the ejector rod retracts inside the sleeve. During mold separation, the scrap material is lifted upwards by the spring, thus facilitating the easy removal of the scrap material and greatly improving the ease of unloading the processed material.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Reference Figure 3-7 As an embodiment of the present utility model, it discloses an in-mold cutting forming mechanism for cold heading of pole post cover plate. Specifically, the forming mechanism includes a lower mold base 1 and a lower mold assembly 2 installed on the lower mold base 1.

[0031] A plurality of guide pillars 11 are fixedly installed on the upper end of the lower mold base 1, and an upper mold base 3 is slidably connected between the plurality of guide pillars 11. Preferably, in this embodiment, four guide pillars 11 are provided, and the four guide pillars 11 are distributed in a matrix on the lower mold base 1. An upper mold 4 is installed on the lower end of the upper mold base 3.

[0032] During installation, the lower mold base 1 is first fixed above the machine base, and the upper mold 4 is connected to the output end of the hydraulic push assembly. The hydraulic push assembly drives the upper mold 4 to move toward the lower mold assembly 2 to achieve mold closing and cutting.

[0033] The lower mold assembly 2 includes a mounting bracket 21 and a lower mold 22. The lower mold 22 has a groove on its end face that fits the entire plate. The lower mold 22 has a plurality of forming holes 23 on its end face. The bottom of the upper mold 4 has a punch 41 that fits the forming holes 23.

[0034] During processing, the plate to be formed is first placed in the groove of the lower mold 22. Then the upper mold 4 moves down to close the mold. The punch 41 at the bottom of the upper mold 4 is pressed into the interior of the forming hole 23 to complete the stamping and cutting of the plate. Since this embodiment uses multiple punches 41 and the forming hole 23, it can adapt to the forming operation of multiple pole cover plates at one time.

[0035] The upper side of the mounting bracket 21 has a lifting assembly 5 that is inserted into the lower mold 22.

[0036] In some embodiments, the mounting bracket 21 of this utility model is fixed to the upper end of the lower mold base 1. An avoidance opening 211 is provided at the upper end of the mounting bracket 21 to avoid the forming hole 23. The avoidance opening 211 is designed to allow the processed product to fall off after forming. Of course, the forming hole 23 should be designed as a through hole, and its hole shape should be adapted to the shape of the processed product to be cut. In addition, the mounting bracket 21 in this embodiment is a U-shaped bracket, and its two ends are fixed to the lower mold base 1 by bolts. The upper end is used to support and connect the lower mold 22.

[0037] Furthermore, in this embodiment, the lifting assembly 5 includes a sleeve 51 fixedly installed on the mounting bracket 21, a push rod 52 is movably inserted into the inner side of the sleeve 51, and a spring 53 is fixedly connected between the bottom of the push rod 52 and the sleeve 51.

[0038] The top end of the push rod 52 extends to the upper side of the lower mold 22. The purpose of the designed lifting component 5 is to lift the entire plate. During mold closing and cutting, the push rod 52 retracts inside the sleeve 51. After cutting, the plate scrap is lifted upward by the resistance of the spring 53, thus realizing convenient removal of the plate scrap.

[0039] It should be noted that, in this embodiment, air holes 42 are provided at the bottom of several of the punches 41, and an air passage structure is provided inside the upper mold 4. The air passage structure is connected to the air holes 42. When positive pressure gas is introduced into the air passage structure, the gas can be discharged through the air holes 42. Thus, when the punches 41 are cutting in the mold, air can be blown onto the cut workpiece so that the workpiece falls down along the forming hole 23, so as to facilitate collection.

[0040] Preferably, the air passage structure in this embodiment includes an air channel 43 formed in the upper mold 4, one end of which extends through to the outside of the upper mold 4 and is connected to a connector 44;

[0041] The air passage 43 is connected to several branch air passages 45 and several air holes 42. In this embodiment, the air passage 43 is the main input air passage, which is connected to the punch 41 through several branch air passages 45. In this way, when the mold is closed and stamped, the cut workpiece is blown downward by positive pressure gas, avoiding the problem of the workpiece getting stuck inside the forming hole 23.

[0042] It should be noted that the lower mold base 1 has a discharge port 12 in the middle, which is used to discharge the processed products. Of course, a collection box can also be placed at the discharge port 12 so that the dropped processed products can be collected in a concentrated manner to improve the convenience of collection.

[0043] The upper mold base 3 and the upper mold 4 are detachably connected; the mounting bracket 21 and the lower mold 22 are detachably connected. Preferably, in this embodiment, the upper mold base 3 and the upper mold 4 can be fixedly connected by bolts. Of course, the mounting bracket 21 and the lower mold 22 can also be connected by bolts. This method is a conventional method for those skilled in the art and will not be elaborated here.

[0044] In summary, in this utility model, the punch 41 at the bottom of the upper mold 4 is pressed into the forming hole 23 to complete the stamping and cutting of the processed product inside the sheet metal. The design of multiple punches 41 and forming holes 23 allows for the simultaneous forming of multiple pole post cover plates. In addition, a lifting component 5 is provided in the lower mold 22 to lift the entire sheet metal. During mold closing and cutting, the ejector rod 52 retracts into the sleeve 51. During mold separation, the scrap sheet is lifted upward by the spring 53, thus facilitating the easy removal of the scrap sheet and greatly improving the ease of unloading the processed product.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
