Description

Technical Field

[0001] The utility model relates to the technical field of loudspeakers, and particularly relates to a stamping machine for a loudspeaker chassis. Background Art

[0002] A loudspeaker is a device that converts an electrical signal into a sound signal, and is an essential component in an audio system for amplifying and playing audio signals. Its working principle is based on electromagnetic induction or piezoelectric effect. In an electromagnetic induction loudspeaker, an electric current passes through a coil to generate a magnetic field, and the magnetic field interacts with a magnet, causing the coil and the connected diaphragm to vibrate, thereby generating sound. In a piezoelectric loudspeaker, a piezoelectric material deforms under the action of an electric field, thereby generating sound.

[0003] Currently, existing loudspeaker chassis are usually formed by stamping with a stamping machine. The stamping process is as follows: The raw material is manually placed by a worker at the stamping part of the stamping machine, and the stamping machine is started to stamp the raw material into a loudspeaker chassis. Then, the worker takes out the stamped loudspeaker chassis, so that the raw material can be stamped again.

[0004] In the above solution, the stamped loudspeaker chassis needs to be taken out by a worker, but the stamped loudspeaker chassis is usually adhered to the mold, resulting in difficulty for the worker to remove it. Content of the Utility Model

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a stamping machine for a loudspeaker chassis. By providing a jacking mechanism, the loudspeaker chassis can be separated from the lower die head, solving the problem that it is inconvenient for workers to remove the loudspeaker chassis in the prior art, thereby improving work efficiency.

[0006] The solution of the utility model to solve the above technical problem is:

[0007] A stamping machine for a loudspeaker chassis includes a machine body. A plurality of guide rods are fixed to the upper end of the machine body. The upper ends of the plurality of guide rods are provided with the same set of driving components. The side walls of the plurality of guide rods are sleeved with the same pressing block. The lower end of the pressing block is fixed with an upper die head. The lower die head is fixed to the upper end of the machine body. A jacking mechanism is provided above the machine body. The jacking mechanism includes a lifting frame, a clamping component and a jacking component.

[0008] When making a speaker chassis, place the raw material at the upper end of the lifting frame, start the driving component, drive the pressing block to move downward. The downward movement of the pressing block drives the upper die head to move downward, making the upper die head abut against the upper end of the lifting frame, and driving the raw material and the lifting frame to move downward to the required position together. Thus, under the action of the upper die head and the lower die head, the raw material is stamped into a speaker chassis. After stamping is completed, control the pressing block to reset, and under the action of the clamping component, clamp and fix the lifting frame that has moved to the required position. Start the jacking component, drive the lifting frame to move upward to the required position, so that the made speaker chassis is separated from the lower die head, facilitating the staff to remove the made speaker chassis.

[0009] By providing a jacking mechanism, the speaker chassis can be separated from the lower die head, solving the problem that it is inconvenient for the staff to remove the speaker chassis in the prior art, thus improving work efficiency.

[0010] The utility model is further set as: The driving component includes a support plate fixed at the upper ends of multiple guide rods at the same time. A hydraulic cylinder is fixed at the upper end of the support plate, and the hydraulic rod of the hydraulic cylinder is fixed at the upper end of the pressing block.

[0011] Through the above technical solution, when it is necessary to drive the pressing block to move, start the hydraulic cylinder, and thus the pressing block can be driven to move.

[0012] The utility model is further set as: The lifting frame includes a first circular plate arranged above the machine body. Multiple sliding rods are fixed at the lower end of the first circular plate. The multiple sliding rods are inserted into the upper end of the machine body, and the extended ends of the multiple sliding rods passing through the machine body are fixed with the same second circular plate.

[0013] Through the above technical solution, when making a speaker chassis, place the raw material at the upper end of the first circular plate, start the driving component, drive the pressing block to move downward. The downward movement of the pressing block drives the upper die head to move downward, making the upper die head abut against the upper end of the first circular plate, and driving the raw material and the first circular plate to move downward to the required position together. Thus, the raw material can be stamped into a speaker chassis, and the second circular plate is driven to move downward to the required position by the multiple sliding rods. After stamping is completed, control the pressing block to reset, and under the action of the clamping component, clamp and fix the second circular plate. Start the jacking component, drive the second circular plate to move upward to the required position, and drive the first circular plate to move upward to the required position by the multiple sliding rods, so that the made speaker chassis can be separated from the lower die head.

[0014] The utility model is further arranged as follows: The clamping component includes a first compression spring sleeved on the side wall of the sliding rod. The lower end of the first compression spring is fixed to the upper end of the second circular plate, and the upper end of the first compression spring is fixed to the inner wall of the machine body. Two connecting plates are symmetrically fixed in the machine body. A round rod is sleeved on the side wall of the connecting plate. A clamping plate is fixed to the end of the round rod. A second compression spring is sleeved on the side wall of the round rod. One end of the second compression spring is fixed to the side wall of the clamping plate, and the other end of the second compression spring is fixed to the side wall of the connecting plate.

[0015] Through the above technical solution, when it is necessary to clamp and fix the second circular plate, when the second circular plate moves downward to squeeze the clamping plate, the clamping plate moves outward, the second compression spring contracts, and at the same time, multiple first compression springs are stretched. When the second circular plate continues to move downward and disengages from the clamping plate, the clamping plate is reset under the action of the second compression spring, so that the clamping plate abuts against the upper end of the second circular plate, controlling the reset of the pressing block. Under the action of multiple first compression springs, the second circular plate is pressed against the lower end of the clamping plate, so that the second circular plate can be clamped and fixed.

[0016] The utility model is further arranged as follows: The jacking component includes a cylinder fixed to the bottom of the machine body, and the push rod of the cylinder abuts against the lower end of the second circular plate.

[0017] Through the above technical solution, when it is necessary to drive the second circular plate to move upward to the required position, start the cylinder to drive the second circular plate to move upward, so that the second circular plate squeezes the clamping plate and then disengages from the clamping plate, and under the action of multiple first compression springs, the second circular plate can be driven to move upward to the required position.

[0018] The utility model is further arranged as follows: A third compression spring is sleeved on the side wall of the guide rod, and the lower end of the third compression spring is fixed to the upper end of the machine body.

[0019] Through the above technical solution, when the hydraulic cylinder drives the pressing block to move downward, by providing the third compression spring, the pressing block can move downward gently and stably.

[0020] The utility model is further arranged as follows: An auxiliary rod is arranged at the upper end of the machine body, and one end of the auxiliary rod is bent.

[0021] Through the above technical solution, after the manufactured speaker frame is separated from the lower die head, by the staff holding the auxiliary rod, the bent end of the auxiliary rod hooks the speaker frame, which further facilitates the staff to remove the speaker frame.

[0022] The beneficial effects of the present utility model are:

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The following will further describe in detail the specific embodiments of the present utility model in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0031] The following is a reference Figures 1 to 3 for the description of the present utility model.

[0032] A speaker frame stamping machine includes a body 1. A plurality of guide rods 2 are fixed to the upper end of the body 1. The upper ends of the plurality of guide rods 2 are provided with the same set of driving components. The side walls of the plurality of guide rods 2 are sleeved with the same pressing block 3. The lower end of the pressing block 3 is fixed with an upper die head 4. A lower die head 5 is fixed to the upper end of the body 1. A jacking mechanism is provided above the body 1. The jacking mechanism includes a lifting frame, a clamping component and a jacking component.

[0033] When the speaker frame 6 needs to be manufactured, place the raw material at the upper end of the lifting frame, start the driving component, drive the pressing block 3 to move downward. The downward movement of the pressing block 3 drives the upper die head 4 to move downward, making the upper die head 4 abut against the upper end of the lifting frame, and driving the raw material and the lifting frame to move downward to the required position together. Thus, under the action of the upper die head 4 and the lower die head 5, the raw material is stamped into the speaker frame 6. After stamping is completed, control the pressing block 3 to reset, and under the action of the clamping component, clamp and fix the lifting frame that has moved to the required position. Start the jacking component, drive the lifting frame to move upward to the required position, so that the manufactured speaker frame 6 is separated from the lower die head 5, thus facilitating the staff to remove the manufactured speaker frame 6.

[0034] By providing a jacking mechanism, the speaker frame 6 can be separated from the lower die head 5, solving the problem that it is inconvenient for the staff to remove the speaker frame 6 in the prior art, thereby improving work efficiency.

[0035] The driving component includes a support plate 7 fixedly arranged at the upper ends of multiple guide rods 2 at the same time. A hydraulic cylinder 8 is fixedly arranged at the upper end of the support plate 7, and a hydraulic rod 801 of the hydraulic cylinder 8 is fixedly arranged at the upper end of the pressing block 3.

[0036] When it is necessary to drive the pressing block 3 to move, start the hydraulic cylinder 8, and thus the pressing block 3 can be driven to move.

[0037] The lifting frame includes a first circular plate 9 arranged above the machine body 1. Multiple sliding rods 10 are fixedly arranged at the lower end of the first circular plate 9. The multiple sliding rods 10 are inserted into the upper end of the machine body 1, and the extended ends of the multiple sliding rods 10 passing through the machine body 1 are fixedly provided with the same second circular plate 11.

[0038] When the speaker frame 6 needs to be manufactured, place the raw material at the upper end of the first circular plate 9, start the driving component, drive the pressing block 3 to move downward. The downward movement of the pressing block 3 drives the upper die head 4 to move downward, making the upper die head 4 abut against the upper end of the first circular plate 9, and driving the raw material and the first circular plate 9 to move downward to the required position together. Thus, the raw material can be stamped into the speaker frame 6, and the second circular plate 11 is driven to move downward to the required position through the multiple sliding rods 10. After stamping is completed, control the pressing block 3 to reset, and under the action of the clamping component, clamp and fix the second circular plate 11. Start the jacking component, drive the second circular plate 11 to move upward to the required position, and drive the first circular plate 9 to move upward to the required position through the multiple sliding rods 10, so that the manufactured speaker frame 6 can be separated from the lower die head 5.

[0039] The clamping component includes a first compression spring 12 sleeved on the side wall of the sliding rod 10. The lower end of the first compression spring 12 is fixed to the upper end of the second circular plate 11, and the upper end of the first compression spring 12 is fixed to the inner wall of the body 1. Two connecting plates 13 are symmetrically fixed in the body 1. A round rod 14 is sleeved on the side wall of the connecting plate 13. A clamping plate 15 is fixed to the end of the round rod 14. A second compression spring 16 is sleeved on the side wall of the round rod 14. One end of the second compression spring 16 is fixed to the side wall of the clamping plate 15, and the other end of the second compression spring 16 is fixed to the side wall of the connecting plate 13.

[0040] When it is necessary to clamp and fix the second circular plate 11, when the second circular plate 11 moves downward to squeeze the clamping plate 15, the clamping plate 15 moves outward, the second compression spring 16 contracts, and at the same time, multiple first compression springs 12 are stretched. When the second circular plate 11 continues to move downward and disengages from the clamping plate 15, the clamping plate 15 is reset under the action of the second compression spring 16, so that the clamping plate 15 abuts against the upper end of the second circular plate 11, controlling the reset of the pressing block 3. Under the action of multiple first compression springs 12, the second circular plate 11 is pressed against the lower end of the clamping plate 15, so that the second circular plate 11 can be clamped and fixed.

[0041] The jacking component includes a cylinder 17 fixed to the bottom of the body 1. The push rod 1701 of the cylinder 17 abuts against the lower end of the second circular plate 11.

[0042] When it is necessary to drive the second circular plate 11 to move upward to the required position, start the cylinder 17 to drive the second circular plate 11 to move upward, so that the second circular plate 11 squeezes the clamping plate 15 and then disengages from the clamping plate 15. Under the action of multiple first compression springs 12, the second circular plate 11 can be driven to move upward to the required position.

[0043] A third compression spring 18 is sleeved on the side wall of the guide rod 2. The lower end of the third compression spring 18 is fixed to the upper end of the body 1.

[0044] When the hydraulic cylinder 8 drives the pressing block 3 to move downward, by providing the third compression spring 18, the pressing block 3 can move downward smoothly and stably.

[0045] An auxiliary rod 19 is provided at the upper end of the body 1. One end of the auxiliary rod 19 is bent.

[0046] After the manufactured speaker chassis 6 is disengaged from the lower die head 5, by the staff holding the auxiliary rod 19, the bent end of the auxiliary rod 19 hooks the speaker chassis 6, which further facilitates the staff to remove the speaker chassis 6.

[0047] Working principle:

[0048] When the speaker frame 6 needs to be manufactured, place the raw material on the upper end of the first circular plate 9, start the hydraulic cylinder 8, drive the pressing block 3 to move downward, the downward movement of the pressing block 3 drives the upper die head 4 to move downward, so that the upper die head 4 abuts against the upper end of the first circular plate 9, and drives the raw material and the first circular plate 9 to move downward to the required position together. Thus, under the action of the upper die head 4 and the lower die head 5, the raw material is stamped into the speaker frame 6, and at the same time, the second circular plate 11 is driven to move downward by multiple sliding rods 10 to squeeze the clamping plate 15, so that the clamping plate 15 moves outward, the second compression spring 16 contracts, and at the same time, multiple first compression springs 12 are stretched. When the second circular plate 11 continues to move downward and disengages from the clamping plate 15, the clamping plate 15 is reset under the action of the second compression spring 16, so that the clamping plate 15 abuts against the upper end of the second circular plate 11. After stamping is completed, control the pressing block 3 to reset. Under the action of multiple first compression springs 12, the second circular plate 11 is pressed against the lower end of the clamping plate 15, so as to clamp and fix the second circular plate 11. Start the cylinder 17, drive the second circular plate 11 to move upward, so that the second circular plate 11 squeezes the clamping plate 15 and then disengages from the clamping plate 15, and under the action of multiple first compression springs 12, drive the second circular plate 11 to move upward to the required position, and drive the first circular plate to move upward to the required position through multiple sliding rods 10, so that the manufactured speaker frame 6 disengages from the lower die head 5. By the staff holding the auxiliary rod 19, the bent end of the auxiliary rod 19 hooks the speaker frame 6, so that it is convenient for the staff to remove the speaker frame 6.

[0049] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art of this technology, without departing from the technical principle of the present invention, several improvements and modifications can be made. These improvements and modifications under the above assumptions should also be regarded as the protection scope of the present invention.
