Description

Technical Field

[0001] This utility model relates to the field of automobile production mold technology, and in particular to a mechanism for solving the problem of scrap sliding out of progressive stamping dies. Background Technology

[0002] Under the premise of ensuring product quality, the essence of competition among enterprises is the competition of efficiency and cost. How to continuously improve production efficiency is not only the key to the sustainable development of enterprises, but also the fundamental way to reduce manufacturing costs. Currently, how to more efficiently and quickly solve the problem restricting production efficiency is a perpetual challenge faced by every automotive parts manufacturer. Therefore, for most automotive stamping parts companies, the traditional multi-machine manual stamping production method can no longer absorb the increasingly high labor costs and low production efficiency, thus leading to the adoption of progressive die production as a replacement. However, the problem of scrap sliding off the machine in progressive die production is a challenge that must be faced during the production process. If it is not properly resolved, it will seriously affect the production cycle and bring huge economic losses to the company.

[0003] like Figure 1 As shown, the production of progressive dies for stamping often results in a significant difference between the die width and the machine tool width. Furthermore, due to limitations in the machine tool's closed height, the angle between the scrap chute 6 and the machine tool table 10 is only 8°. Scrap material, after falling freely from the die, cannot slide off the machine tool table and into the scrap collection box. During stamping production, to prevent scrap from clogging the die's discharge holes and causing die damage, operators must manually clean the scrap approximately every 200 pieces produced. Most component stamping suppliers require that no more than three scrap pieces accumulate, and automated stamping lines require that every scrap piece slides smoothly off the machine. These bottlenecks severely reduce the stamping cycle time, causing equipment downtime and increasing the workload for operators. For example, with a single-shift production plan of 3000 pieces for automated progressive dies, the production plan requires 14 downtimes for scrap cleaning, each lasting 5 minutes. Typically, the production cycle time for automated progressive dies is 15 times per minute. A single production run with a cumulative downtime of 70 minutes could result in an additional 1050 strokes produced, representing one-third of the rated production time, leading to significant economic losses for the company. Summary of the Invention

[0004] The purpose of this invention is to provide a mechanism to solve the problem of difficult material sliding out of progressive stamping dies, thereby addressing the aforementioned issues.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a mechanism for solving the difficulty of scrap sliding out of progressive stamping dies, comprising a fixed unit and a movable unit connected to each other, wherein,

[0006] The fixing unit includes two cylinders disposed on two machine tool columns and a first crossbar disposed between the two machine tool columns. The two ends of the first crossbar are respectively connected to the output shaft of the cylinders, and the two sides are kept at the same height. The cylinders are fixedly connected to the machine tool columns.

[0007] The movable unit includes a waste material chute, a slot, and a second crossbar. One end of the waste material chute is fixedly connected to the slot, and the other end is placed on the second crossbar and fixed to the mold with screws after height adjustment. The adjusted height ensures that the angle of the waste material chute after installation is greater than 3°, so that the waste material can slide out of the machine tool during production. The slot is slidably connected to the first crossbar, wherein the height of the slot exceeds the thickness of the first crossbar by 20-30mm to ensure that the slot and waste material chute assembly does not detach from the first crossbar during production. At the same time, a 3-5mm gap is left between the slot and both sides of the first crossbar to facilitate quick replacement of the waste material chute with the matching mold during production mold changes.

[0008] As a preferred technical solution, the cylinder and the machine tool column are fixedly connected by a fixed corner flange and screws.

[0009] As a preferred technical solution, the cylinder's piping system is connected to the machine tool's air circuit. The machine tool's own control system controls the opening and closing of the compressed air in the cylinder, thus eliminating the need for an additional air source and control system.

[0010] Compared with the prior art, the advantages of this utility model are as follows: by adopting this utility model, unnecessary shutdowns are eliminated in the single-shift production plan, and it is estimated that the annual downtime loss can be reduced by about 500,000 yuan; therefore, the investment in the mechanism of this utility model improves production efficiency and has broad application prospects.

[0015] The present invention will be further described below with reference to the embodiments.

[0016] Example:

[0017] See Figure 2 A mechanism to prevent scrap from slipping out of a progressive die for stamping includes a fixed unit and a movable unit connected to each other. The fixed unit includes two cylinders 1 mounted on two machine tool columns 9 and a first crossbar 4 positioned between the two machine tool columns 9. The two ends of the first crossbar 4 are connected to the output shafts of the cylinders 1, ensuring that both sides are at the same height. The cylinders 1 are fixedly connected to the machine tool columns 9, and the vertical and horizontal positions of the first crossbar 4 are consistent. In this embodiment, the cylinders 1 are fixedly connected to the machine tool columns 9 via fixed corner flanges 2 and screws 3. The piping system of the cylinders 1 is connected to the machine tool's air circuit, and the opening and closing of the compressed air in the cylinders is controlled by the machine tool's own control system. The first crossbar 4 is fixed to the front ends of the cylinders 1 mounted on both sides of the machine tool columns 9 with nuts 5 and leveled. Once the fixed unit is installed and put into use, it does not require disassembly or assembly during routine maintenance.

[0018] The movable unit includes a waste material chute 6, a slot 7, and a second crossbar 8. One end of the waste material chute 6 is fixedly connected to the slot 7, and the other end is placed on the second crossbar 8. After height adjustment, it is fixed to the mold with screws. The adjusted height ensures that the angle of the waste material chute after installation is >3°, allowing the waste material to slide out of the machine tool during production. The slot 7 is slidably connected to the first crossbar 8. The slot is slidably connected to the first crossbar, wherein, as... Figure 3 As shown, the height of the slot 7 exceeds the thickness of the first crossbar 4 by 30mm, ensuring that the combination of the slot 7 and the waste material chute 6 does not fall off the first crossbar 4 during production; at the same time, a 3-5mm gap is left between the inner side of the slot 7 and the two sides of the first crossbar 4, so as to quickly replace the waste material chute 6 with the matching mold during production mold change.

[0019] The operating principle of this utility model is as follows: the waste material chute 6 is made according to the width required for the mold to slide out waste material, and is welded to the slot 7. Numbering is made on the waste material chute 6 and the corresponding position of the mold.

[0020] When installing the mold, place the rear end of the waste material chute 6 on the second crossbar 8 installed on the mold according to the corresponding number, and fix the front end of the waste material chute 6 to the first crossbar 4 through the slot 7;

[0021] During production, the air circuit system of cylinder 1 is connected, and cylinder 1 realizes the reciprocating motion of the machine tool in the front and back directions, thereby driving the first crossbar 4 fixed at its front end and the waste material slide 6 to keep reciprocating motion in the front and back directions, so as to slide the waste material that falls into the waste material slide 6 from inside the mold out to the waste material collection box outside the machine tool.

[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
