Description

Technical Field

[0001] The utility model relates to extrusion molding equipment, in particular to extrusion molding equipment for processing agricultural machine stamping parts, belonging to the technical field of stamping parts. Background Art

[0002] The plastic processing technology of using die pressure to deform the sheet material to obtain parts with certain shapes, sizes and properties is called stamping, and the parts obtained after stamping are called punching parts. The geometric shape, size and precision of punching parts have a great influence on the stamping process. The processability of punching parts refers to the adaptability of punching parts to stamping processability. Punching parts with good processability are conducive to saving materials, reducing forming processes, improving mold life and product quality, including stamping parts used in agricultural machinery. Extrusion molding equipment is needed when processing stamping parts;

[0004] When stamping parts into special-shaped parts, the parts cannot be directly taken out of the mold because their shapes have changed. The parts will be stuck in the mold. When the mold itself does not have the function of splicing and separation, the stuck mold will affect the normal stamping work of subsequent parts, making it impossible for the equipment to continue to process subsequent parts, which will lead to a decrease in the overall efficiency of the stamping work. For this reason, an extrusion molding equipment for processing agricultural machinery stamping parts is proposed. Utility Model Content

The stamping work of the equipment on different types of parts is improved, and the scope of use of the equipment is increased.

[0016] Second, the utility model can limit the thread block by setting the slide bar, so as to prevent the thread block from rotating synchronously with the bidirectional threaded rod, and then unable to drive the lower templates to be spliced ​​and separated with each other. By setting the moving groove, the installation rod can be limited to avoid the offset of the thread block when moving, resulting in the inability of the lower templates to fit each other, so that the shape of the parts changes during stamping, affecting the normal stamping of the parts.

DETAILED DESCRIPTION

[0024] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0025] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0026] Example 1

[0027] like Figure 1-4 As shown, the embodiment of the utility model provides an extrusion molding device for processing agricultural machine stamping parts, including a box body 1, support rods 4 are fixedly installed around the bottom of the box body 1, a mounting plate 5 is fixedly installed at the bottom of the outer surface of the support rod 4, a frame 6 is fixedly installed on the top of the box body 1, and a cylinder 7 is fixedly installed on the top of the frame 6;

[0028] A splicing mechanism 2 is provided at the bottom of the mounting plate 5, and the splicing mechanism 2 includes a motor 201, and the motor 201 is fixedly installed at the bottom of the mounting plate 5, and the output end of the motor 201 is fixedly connected with a bidirectional threaded rod 202, and the upper and lower sides of the outer surface of the bidirectional threaded rod 202 are both connected with thread blocks 203 through threads, and the inner sides around the thread blocks 203 are movably connected with connecting rods 204, and the outer side of the connecting rod 204 is movably connected with a clamping plate 205, and the outer side of the clamping plate 205 is fixedly installed with a fixing block 206, and the outer side of the fixing block 206 is fixedly installed with a mounting rod 207.

[0029] By setting up the splicing mechanism 2, the molds can be spliced ​​and separated with each other, avoiding the situation where the parts are stuck in the mold and cannot be removed due to changes in their appearance when being stamped into special-shaped parts, thereby affecting the normal processing of subsequent parts, improving the stamping work of the equipment on different types of parts, and increasing the scope of use of the equipment.

[0030] Example 2

[0031] In one embodiment, a slide bar 209 is fixedly installed at the bottom of the box body 1, and the slide bar 209 passes through the inner surface of the threaded block 203 and extends to the top of the mounting plate 5. Moving grooves 208 are opened around the bottom of the inner cavity of the box body 1. The mounting rod 207 passes through the inner cavity of the moving groove 208 and extends into the inner cavity of the box body 1. A mounting mechanism 3 is arranged at the bottom of the cylinder 7. The mounting mechanism 3 includes a first mounting block 301, which is fixedly installed at the bottom of the cylinder 7. An upper mold 303 is arranged at the bottom of the first mounting block 301. The left and right sides of the top of the first mounting block 301 are both threadedly connected with first screws 302. A second mounting block 304 is fixedly installed on the inner side of the mounting rod 207, and a second screw 305 is threadedly connected to the outer side of the second mounting block 304. A lower mold 306 is arranged on the inner side of the second mounting block 304.

[0032] By setting the sliding rod 209, the threaded block 203 can be limited, preventing the threaded block 203 from rotating synchronously with the bidirectional threaded rod 202, and then being unable to drive the lower template 306 to be spliced ​​and separated with each other. By setting the moving groove 208, the installation rod 207 can be limited, preventing the threaded block 203 from offset when moving, resulting in the lower templates 306 being unable to fit together, causing the shape of the parts to change during stamping, affecting the normal stamping of the parts. By setting the installation mechanism 3, molds of different shapes can be easily installed, thereby increasing the range of parts that can be stamped and formed by the equipment and improving the practicability of the equipment.

[0033] Example 3

[0034] In one embodiment, a screw groove 309 is provided on the top of the upper mold 303 and the outer side of the lower mold 306, the second screw 305 and the first screw 302 are threadedly connected to the inner cavity of the screw groove 309, a limiting groove 307 is provided at the bottom of the inner cavity of the box body 1, a limiting block 308 is fixedly installed at the bottom of the lower mold 306, the limiting block 308 is slidably connected to the inner cavity of the limiting groove 307, and an oblique opening 310 is provided on the outer side of the lower mold 306, and the angle of the oblique opening 310 is 45°.

[0035] By setting the screw groove 309, the assembly structure is relatively simple, which can save replacement time when replacing the upper mold 303 and the lower template 306. By setting the limit block 308 and the limit groove 307, the moving direction of the lower template 306 can be limited to avoid deviation during movement, which causes the lower templates 306 to be unable to fit tightly, causing the shape of the parts to change during stamping and affecting the normal stamping work. By setting the bevel 310, the fit of the lower templates 306 when spliced ​​together can be improved, thereby enhancing the tightness of the splicing between the lower templates 306.

[0036] When the utility model is working, the lower mold 306 and the upper mold 303 of the appropriate type are selected according to the shape of the required punching, and then the upper mold 303 is fixed to the bottom of the first mounting block 301 through the cooperation between the first screw 302, the second screw 305 and the screw groove 309, and the lower mold 306 is fixed to the inner side of the second mounting block 304, and then the output end of the motor 201 drives the bidirectional threaded rod 202 to rotate, at this time, the threaded block 203 moves outward, and the connecting rod 204 is turned outward, at this time, with the turning of the connecting rod 204, the clamping plate 205, the fixing block 206, and the mounting rod 207 are synchronously After moving inward, the lower template 306 is close to and fits each other, and the part is placed on the inner side of the lower template 306. The cylinder 7 extends downward and drives the first mounting block 301 and the upper mold 303 to move, thereby realizing the stamping work of the part. Subsequently, the output of the motor 201 drives the bidirectional threaded rod 202 to rotate in the opposite direction. At this time, the threaded block 203 moves inward, the connecting rod 204 flips inward, and pushes the fixed block 206, the mounting rod 207, the second mounting block 304 and the lower template 306 to move outward synchronously, and then the part with the changed shape can be taken out to complete the overall work of the equipment.

[0037] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
