Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, specifically to a sheet metal stamping device that facilitates loading and unloading. Background Technology

[0002] Sheet metal stamping is a process that uses molds to form metal sheets. The metal sheet is placed in the mold by a stamping press and stamped into the required shape and size using high pressure. Stamping can process various materials, including aluminum, copper, stainless steel, etc., and is widely used in automobile production.

[0003] For example, Chinese patent application CN111545619B discloses a sheet metal stamping forming equipment, including an outer frame, a horizontal stamping mechanism, a vertical stamping mechanism, and an angle-adjusting stamping mechanism. The vertical stamping mechanism is installed on the inner wall above the outer frame, the horizontal stamping mechanism is installed on the vertical stamping mechanism, and the angle-adjusting stamping mechanism is installed inside the left and right sides of the vertical stamping mechanism.

[0004] However, this sheet metal stamping equipment cannot directly stamp sheet metal parts with negative angles. It usually requires secondary processing, and the processed sheet metal parts need to be loaded and unloaded manually, resulting in high labor costs and low processing efficiency.

[0005] Based on this, the present invention designs a sheet metal stamping device that facilitates loading and unloading to solve the above problems. Utility Model Content

The lower die fixing seat is fixedly installed on the processing table of the stamping machine. The lower die base, the fixing block, and the limiting block are fixedly installed sequentially from left to right on the upper end of the lower die fixing seat. The inclined push block is slidably installed on the upper end of the fixing block. A supporting block is slidably arranged between the lower die base and the fixing block. A floating structure is arranged between the lower end of the supporting block and the lower die fixing seat. The floating structure is used for the supporting block to float up and down. The two positioning blocks are respectively fixedly installed on the upper ends of the lower die base and the inclined push block to cooperate with the limiting sheet metal parts. The tension spring is located inside the inclined push block. The two ends of the tension spring are respectively fixedly connected to the inclined push block and the limiting block. The inclined push block and the limiting block are in abutting connection. The upper end of the lower die fixing seat is connected to the upper die component.

[0012] Furthermore, the lower mold base is inclined towards the support block and is used to form sheet metal parts by cooperating with the upper mold component. The inclined push block is recessed towards the support block and is used to form negative angles of sheet metal parts by cooperating with the upper mold component. The inclined push block is inclined towards the limit block and is used to cooperate with the upper mold component. The two positioning blocks are symmetrically arranged on the left and right, and the positioning blocks are L-shaped.

[0013] Furthermore, the upper die component includes an upper die fixing seat, an upper die base, a lower pressure block, multiple limiting rods, and an ejector rod. The upper die fixing seat is fixedly installed at the lower end of the output end of the stamping machine. The upper die base and the lower pressure block are fixedly installed at the lower end of the upper die fixing seat. The lower end of the upper die base is irregularly shaped to match the lower die base and the inclined push block. The lower left side of the lower end of the lower pressure block is inclined to match the inclined push block. One end of the multiple limiting rods is fixedly installed at the lower end of the upper die fixing seat, and the other end of the limiting rods passes through the lower die fixing seat and is slidably connected to the lower die fixing seat. The ejector rod is fixedly installed at the top inside the stamping machine. The ejector rod does not move with the output end of the stamping machine. The ejector rod passes through the upper die fixing seat and the upper die base and is slidably connected. The ejector rod is a demolding component.

[0014] Furthermore, the automatic loading and unloading assembly includes a loading component and an unloading component, which are mounted on the processing table of the stamping machine.

[0017] Compared with the prior art, the advantages of this utility model are as follows: 1. By cooperating with the lower mold component and the upper mold component, the shape and negative angle of the sheet metal part are formed in one step, avoiding secondary processing and improving production efficiency. By setting the demolding component, the sheet metal part is prevented from being driven to move synchronously when the upper mold component rises due to the negative angle part, which would affect the subsequent loading and unloading of sheet metal parts.

[0018] 2. By setting the ejector block and ejector spring, the sheet metal parts with negative angles will not be driven up by the upper mold base, thus avoiding the impact on subsequent loading and unloading. Automatic loading is achieved by pushing the sheet metal parts inside the storage box through the push plate. With the setting of the positioning block, the positioning block only limits the unprocessed sheet metal parts, so that the processed sheet metal parts can be pushed off the box while loading. The simple structure realizes the automatic loading and unloading of sheet metal parts, resulting in high production efficiency. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the left view.

[0029] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-5 A sheet metal stamping device for easy loading and unloading, including a stamping assembly 1 and an automatic loading and unloading assembly 2;

[0030] The stamping assembly 1 includes a stamping machine 11, a lower die component 12 for cooperating with the oblique push to form a negative angle and the lower shape of the sheet metal part, and an upper die component 13 for pressing down to provide oblique pushing force and forming the upper shape of the sheet metal part. The lower die component 12, the upper die component 13 and the automatic loading and unloading assembly 2 are mounted on the stamping machine 11. The lower die component 12 and the upper die component 13 are connected. A demolding component is provided on the inner side of the upper die component 13.

[0031] When the sheet metal stamping device that facilitates loading and unloading is in normal use, the automatic loading and unloading assembly 2 loads the sheet metal parts, the stamping machine 11 is started, and the stamping machine 11 drives the lower die assembly 12 to press down. While the lower die assembly 12 presses down on the sheet metal parts, it also drives the upper die assembly 13 to push the sheet metal parts from the side, so that the inner side of the sheet metal parts forms a negative angle. When the stamping machine 11 drives the upper die assembly 13 to rise, the demolding component on the inner side of the upper die assembly 13 demolds the formed sheet metal parts, preventing the sheet metal parts from moving with the upper die assembly 13. Through the cooperative setting of the lower die assembly 12 and the upper die assembly 13, the shape and negative angle of the sheet metal parts are formed in one step, avoiding secondary processing and improving production efficiency. Through the setting of the demolding component, the sheet metal parts are prevented from being moved synchronously by the upper die assembly 13 when it rises due to the negative angle part, which would affect the subsequent loading and unloading of sheet metal parts.

[0032] The lower die component 12 and the automatic loading and unloading assembly 2 are installed on the processing table of the stamping machine 11, and the upper die component 13 is installed at the lower end of the output end of the stamping machine 11.

[0033] The lower die component 12 includes a lower die fixing seat 121, a lower die base 122, a fixing block 123, an inclined push block 124, a limiting block 125, a supporting block 126, a floating structure 127, two positioning blocks 128, and a tension spring 129. The lower die fixing seat 121 is fixedly installed on the processing table of the stamping machine 11. From left to right, the lower die base 122, the fixing block 123, and the limiting block 125 are fixedly installed on the upper end of the lower die fixing seat 121. The inclined push block 124 is slidably installed on the upper end of the fixing block 123. The lower die base 122 and the fixing block 123 are connected between them. A sliding support block 126 is provided. A floating structure 127 is provided between the lower end of the support block 126 and the lower mold fixing seat 121. The floating structure 127 is used for the support block 126 to float up and down. Two positioning blocks 128 are respectively fixedly installed on the lower mold base 122 and the upper end of the inclined push block 124 to cooperate with the limiting sheet metal parts. The tension spring 129 is located inside the inclined push block 124. The two ends of the tension spring 129 are fixedly connected to the inclined push block 124 and the limiting block 125 respectively. The inclined push block 124 and the limiting block 125 are in abutting connection. The upper end of the lower mold fixing seat 121 is connected to the upper mold component 13.

[0034] The lower mold base 122 is inclined towards the support block 126 and cooperates with the upper mold component 13 for sheet metal forming. The inclined push block 124 is recessed towards the support block 126 and cooperates with the upper mold component 13 for negative angle forming of sheet metal. The inclined push block 124 is inclined towards the limit block 125 and cooperates with the upper mold component 13. The two positioning blocks 128 are symmetrically arranged on the left and right sides. The positioning blocks 128 are L-shaped.

[0035] The floating structure 127 consists of two slide rods and two springs sleeved on the outside of the slide rods. One end of the slide rod is fixedly connected to the support block 126, and the other end of the slide rod is slidably connected to the lower mold fixing seat 121. Both ends of the springs are fixedly connected to the lower mold fixing seat 121 and the support block 126, respectively. The lower mold fixing seat 121 is provided with a groove for accommodating the springs.

[0036] The upper die component 13 includes an upper die fixing seat 131, an upper die base 132, a lower pressure block 133, multiple limiting rods 134, and an ejector rod 135. The upper die fixing seat 131 is fixedly installed at the lower end of the output end of the stamping machine 11. The upper die base 132 and the lower pressure block 133 are fixedly installed at the lower end of the upper die fixing seat 131. The lower end of the upper die base 132 is irregularly shaped to match the lower die base 122 and the inclined push block 124. The lower left side of the lower end of the lower pressure block 133 is fitted with the inclined push block 124. 4. The device is inclined. One end of multiple limiting rods 134 is fixedly installed at the lower end of the upper mold fixing seat 131. The other end of the limiting rod 134 passes through the lower mold fixing seat 121 and is slidably connected to the lower mold fixing seat 121. The ejector rod 135 is fixedly installed at the top inside the stamping machine 11. The ejector rod 135 does not move with the output end of the stamping machine 11. The ejector rod 135 passes through the upper mold fixing seat 131 and the upper mold seat 132 and is slidably connected. The ejector rod 135 is a demolding component.

[0037] The automatic loading and unloading assembly 2 includes a loading component 21 and an unloading component 22. The loading component 21 and the unloading component 22 are installed on the processing table of the stamping machine 11. The unloading component 22 and the loading component 21 are located in front of and behind the lower die fixing seat 121, respectively.

[0038] The feeding component 21 includes a mounting frame 211, a storage box 212, a push plate 213, and a cylinder 214. The mounting frame 211 is fixedly mounted on the processing table of the stamping machine 11. The storage box 212 is fixedly mounted on the upper front side of the mounting frame 211. A gap is provided between the front and rear ends of the mounting frame 211 and the storage box 212. The gap can only allow one sheet metal part to pass through. The push plate 213 is slidably mounted on the upper end of the mounting frame 211. The push plate 213 is an L-shaped plate. The front end of the push plate 213 has the same thickness as a sheet metal part. The rear end of the push plate 213 is fixedly connected to the output end of the cylinder 214. The cylinder 214 is fixedly mounted on the upper end of the mounting frame 211.

[0039] The feeding component 22 includes a bracket 221 and a feeding trough plate 222. The bracket 221 is fixedly installed on the feeding trough plate 222, and the feeding trough plate 222 is fixedly installed on the processing table of the stamping machine 11. The bracket 221 is gradually inclined downward from back to front.

[0040] When the sheet metal stamping device, which facilitates loading and unloading, is in normal use, multiple sheet metal parts are placed inside the storage box 212. The cylinder 214 is activated, which drives the push plate 213 to move along the mounting bracket 211. The push plate 213 pushes the sheet metal part at the bottom inside the storage box 212 to be limited between the two positioning blocks 128. The stamping machine 11 is then activated, which drives the upper die fixing seat 131, the upper die seat 132, and the lower pressing block 133 to press down. The upper die seat 132 drives the sheet metal part... The sheet metal part contacts the support block 126. Under the clamping of the upper die base 132 and the support block 126, the sheet metal part continues to move downward. The lower pressing block 133 contacts the inclined push block 124 and gradually drives the inclined push block 124 to move to the left. The sheet metal part is formed under the action of the upper die base 132, the lower die base 122, the support block 126 and the inclined push block 124. The inclined push block 124 cooperates with the upper die base 132 to form the negative angle of the sheet metal part. The stamping is completed. The upper die fixing seat 131 drives the upper die base 132 and the lower pressing block 133 to move upward. The support block 126, under the action of the floating structure 127, drives the sheet metal part to rise. The ejector rod 135 pushes the negative angle part of the sheet metal part out of the upper mold base 132. The tension spring 129 drives the inclined push block 124 to reset. The start cylinder 214 continues to feed material. The new sheet metal part moves to the positioning block 128. Because the stamped sheet metal part is bent upward, it is not restricted by the positioning block 128 and is thus pushed by the new sheet metal part to fall into the unloading groove plate 222 for unloading. Through the ejector block 135 and the top... The spring 136 prevents the sheet metal parts with negative angles from being lifted by the upper mold base 132, thus avoiding any impact on subsequent loading and unloading. Automatic loading is achieved by pushing the sheet metal parts inside the storage box 212 through the push plate 213. With the positioning block 128, the positioning block 128 only limits the unprocessed sheet metal parts, allowing the finished sheet metal parts to be pushed off the ground while loading. The simple structure achieves automatic loading and unloading of sheet metal parts, resulting in high production efficiency.
