Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a pipe clamp processing mold. Background Technology

[0002] Pipe clamps are a common component in construction, frequently used for fixing and securing perimeter fencing. Existing pipe clamp manufacturing dies include a stamping punch and a matching stamping die. A steel plate is placed between the punch and die, and the punch presses and shapes the plate as it moves downwards. Currently, most existing pipe clamp dies can only produce single-pipe clamps, not double-pipe clamps, limiting their functionality. Traditional methods for manufacturing double-pipe clamps involve welding or rolling single-pipe clamps, but these methods are costly and inefficient.

[0003] Existing patent CN107297419A discloses a pipe clamp processing mold, including an upper mold assembly and a lower mold assembly. The upper mold assembly includes a top seat, a connecting rod, and a connecting plate. The connecting plate is fixedly connected to a press. One end of the connecting rod is welded perpendicularly to the connecting plate, and the other end is welded perpendicularly to the top seat. The top seat is equipped with a left upper column, a left upper arc-shaped punch, a middle upper column, a right upper arc-shaped punch, and a right upper column, which are welded side by side from one end to the other. The left upper column and the right upper column are symmetrically located on both sides of the middle upper column, and the left upper arc-shaped punch and the right upper arc-shaped punch are also symmetrically located on both sides of the middle upper column. Although the above-mentioned mold can produce double-tube clamps in one step, it still has some problems in use: the upper left column, upper left arc-shaped punch, upper middle column, upper right arc-shaped punch, and upper right column of the mold are all connected to the top seat by welding; the lower column, lower left arc-shaped die, lower middle column, lower right arc-shaped die, and lower right column are all connected to the base plate by welding. The length of the connecting section between the double-tube clamps formed by stamping is fixed. If the double-tube clamp clamp with a connecting section of other length is to be produced, the entire upper mold assembly and lower mold assembly need to be disassembled and new upper mold assembly and lower mold assembly need to be remade according to the requirements, which is a complicated and cumbersome process.

[0029] The present invention will be further described below with reference to specific embodiments. The purpose of this description is only to better understand the content of the present invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0030] A pipe clamp processing mold consists of a pressure assembly 1, an upper mold assembly 2, and a lower mold assembly 3. The pressure assembly 1 consists of a mounting plate 101 and hydraulic rods 102. The mounting plate 101 is fixed at a corresponding position on the production site. Four hydraulic rods 102 are respectively installed on the lower surface of the mounting plate 101. The telescopic ends of the hydraulic rods 102 are connected to the upper mold assembly 2.

[0031] In this embodiment, the upper mold assembly 2 consists of a top seat 201, a first punch 202, and a second punch 203. Several pads 204 are installed between the first punch 202 and the second punch 203. Fixing plates 4 are respectively provided on the front and rear sides of the first punch 202, the second punch 203, and the pads 204. After the pads 204 are placed between the first punch 202 and the second punch 203, they are fixed and locked by bolt assemblies that pass through the fixing plates 4.

[0032] The lower surface of the top seat 201 is provided with a dovetail groove 205 in the middle. The top of the punch 202, punch 203 and pad 204 are respectively provided with dovetail blocks 206 that are adapted to the dovetail groove 205. The punch 202, punch 203 and pad 204 are slidably connected to the top seat 201 through the insertion and engagement of the dovetail blocks 206 and the dovetail groove 205.

[0033] The lower mold assembly 3 consists of a base 301, a first die 302, and a second die 303. The first die 302 is adapted to the first punch 202, and the second die 303 is adapted to the second punch 203. Several second pads 304 are installed between the first die 302 and the second die 303. Fixing plates 4 are respectively provided on the front and rear sides of the first die 302, the second die 303, and the second pads 304. After the second pads 304 are placed between the first die 302 and the second die 303, they are also fixed and locked by bolt assemblies that pass through the fixing plates 4.

[0034] In this embodiment, the arc-shaped punch head 207 adapted to the pipe clamp on punch one 202 and punch two 203 is placed on the front side of their respective punches, and the front side of the upper surface of die one 302 and die two 303 is respectively provided with a groove 307 adapted to the punch head 207.

[0035] A dovetail groove 305 is provided in the middle of the upper surface of the base 301. The lower ends of the die 1 302, die 2 303 and pad 2 304 are respectively provided with dovetail blocks 306 that are adapted to the dovetail groove 305. The die 1 302, die 2 303 and pad 2 304 are slidably connected to the base 301 through the insertion and engagement of the dovetail blocks 306 and the dovetail groove 305.

[0036] The top of the base 301 has telescopic rods 5 near its four corners. Each telescopic rod 5 consists of a fixed rod 501, a second spring 502, and a telescopic sleeve 503. The fixed rod 501 is fixedly connected to the base 301, and the second spring 502 is fitted onto the outside of the fixed rod 501. The lower end of the second spring 502 is fixed to the base 301, and the upper end of the second spring 502 is fixedly connected to the lower end of the telescopic sleeve 503. The bottom of the top seat 201 has corresponding limiting sleeves 6 at its four corners, which are slidably inserted into each other. During the stamping process, the limiting sleeves 6 are fitted onto the telescopic sleeves 503. During the downward pressing process, the second spring 502 contracts, causing the telescopic sleeves 503 to contract and store energy, preventing damage to the steel plate due to excessive pressure. Furthermore, during the upward movement of the hydraulic rod 102, energy is released to help it return to its original position.

[0037] In this embodiment, two adjusting through slots 209 are opened parallel to each other on the upper surface of the top seat 201 corresponding to the position of the dovetail groove 205. L-shaped fixing plates 208 are respectively provided on the outer side of the punch 202 and the punch 203. The fixing plates 208 are placed upside down and closely attached to the outer side of their corresponding punches. Then, the fixing plates 208 are locked and fixed to the top seat 201 by bolt assembly.

[0038] Two adjusting through slots 309 are opened parallel to each other on the lower surface of the base 301, corresponding to the position of the dovetail groove 305. L-shaped fixing plates 308 are respectively provided on the outer side of the die 1 302 and die 2 303. The fixing plates 308 are tightly attached to the outer side of their corresponding dies, and then the fixing plates 308 are locked and fixed to the base 301 by bolt assembly.

[0039] The bottom of die 1 (302) and die 2 (303) are respectively provided with mounting grooves 1 (9). The interior of mounting groove 1 (9) is fixed to the lower end of spring 10, and the upper end of spring 10 is fixed to ejector rod 11. Ejector rod 11 slides up and down along the inner wall of mounting groove 1 (9). When the punch applies pressure to the workpiece, ejector rod 11 moves downward to retract spring 10. After the pressure is applied, hydraulic rod 102 lifts the punch to reset, and spring 10 ejects ejector rod 11 to quickly lift the pipe clamp.

[0040] In this embodiment, the upper surfaces of die one 302 and die two 303 are provided with mounting grooves 12 near their respective outer edges. A screw 13 is rotatably connected inside the mounting groove 12, and a self-locking handwheel 14 (a conventional product) is provided at the outer end of the screw 13. A limiting plate 15 is threadedly connected to the screw 13, and the limiting plate 15 is placed inside the mounting groove 12. According to the length of the workpiece (before processing), the distance between the two limiting plates 15 is adjusted by rotating the screw 13 through the self-locking handwheel 14, so as to satisfy the limiting of the workpiece.

[0041] In this embodiment, guide rods 7 are installed on the rear side of the lower surface of punch 1 202 and punch 2 203 respectively, and insertion holes 8 adapted to guide rods 7 are opened on the upper surface of die 1 302 and die 2 303 respectively. The guide rods 7 and insertion holes 8 are positioned correspondingly, so that the workpiece can fit perfectly during the die closing process.

[0042] When using this mold, select the appropriate punch and die according to the curvature of the pipe clamp to be produced. Then, determine the required quantity of shims 1 (204) and shims 2 (304) based on the length of the connecting section between the two pipe clamps, and then assemble and fix them separately. After assembly and debugging, processing begins. During stamping, the workpiece is placed above shims 1 (302) and shims 2 (303). The hydraulic rod 102 drives the top seat 201 downward, causing punches 1 (202) and shims 2 (203) to descend. During the descent, the guide rod... 7. Insert the insert into the socket 8 and move downward along the socket 8. The limiting sleeve 6 is fitted outside the telescopic sleeve 503 and presses the second spring 502 to retract. After the first punch 202 and the second punch 203 contact the workpiece, they continue to move into the first die 302 and the second die 303. At the same time, the first punch 202 and the second punch 203 press the workpiece downward until the mold is closed. After the stamping is completed, the hydraulic rod 102 drives the top seat 201 to rise and reset. The push rod 11 springs upward under the action of the first spring 10, quickly lifting the formed pipe clamp.

[0043] This invention sets the upper and lower mold components as detachable slot structures, and sets the punch and die in separate blocks. Appropriate backing plates can be selected for assembly according to requirements. It can be used to process double tube clamps with connection sections of different sizes, which increases the frequency of use of the punch and die and simplifies the installation process.
